Field of the Invention

The present invention relates to a position adjustment system that enables remote adjustment of the position of the sensing element that enables the workpiece to be sensed in a system where processing is performed on the workpiece.

In particular, the present invention relates to a position adjustment system that enables the position of a sensing element, such as a proximity sensor, to be detected by remote control in a system where operations are performed on the workpiece, such as a computer aided numerical control CNC lathe.

State of the Art

A lathe chuck, which ensures that the workpiece is held firmly during the process and thus helps in machining, is used in systems such as the CNC lathe, which provides the process of turning the workpiece by turning the same after cutting. There are usually two proximity sensors as sensing element in the chuck puller roller, which is connected with the chuck and helps to clamp the workpiece so as to keep the same stable. The main task of these sensors is to check the clamping state of the workpiece of the chuck and to determine that if the clamping is sufficient, there is no problem in the rotation of the chuck and starting the system. As long as the diameter value of the workpieces does not change during the operations, the position of these sensors is not required to change. However, if the workpiece to be processed has a different diameter value, the position setting of the relevant sensor must be re-adjusted due to the change in the final position of the chuck jaws. This adjustment process is performed manually by the user/operator by entering the lathe machine. Therefore, before each different diameter workpiece is processed, the user must enter the machine and re-adjust the sensor position by turning the nut on the proximity sensor with a wrench. This situation causes both the workload and the total processing time to increase and an unsafe operation for the user.

In a patent document numbered US 11117237B2, which is in the state of the art, a machine tool provided with spindle having measurement function is described. Said machine tool includes: a hollow spindle including a hollow portion along an axial direction; a plurality of chuck claws openably mounted at a distal end portion of the hollow spindle, and configured to hold a workpiece; an operation rod inserted into the hollow portion of the hollow spindle in a movable manner, and configured to close the plurality of chuck claws with movement of the operation rod toward one side in the axial direction and open the plurality of chuck claws with movement of the operation rod toward the other side in the axial direction; and a measuring apparatus that is configured to measure an opening dimension of the plurality of chuck claws based on a movement amount of the operation rod, can be a stroke sensor.

In the mentioned document, there is no mention of a solution for adjusting the position of the measuring device by remote control and preventing the user from entering the machine for position adjustment.

As a result, in a system where processing is applied on the workpiece, especially the CNC lathe, there is a need to develop a position adjustment system that allows the detection of the clamping state of the workpiece and allowing the system to operate, allowing the physical position of the sensing or measuring element to be adjusted by remote control, thus preventing the user from needing to enter the system before applying any different workpieces.

Aim of the Invention

In particular, the present invention relates to a position adjustment system that enables the position of a sensing element, such as a proximity sensor, to be detected by remote control in a system where operations are performed on the workpiece, such as a computer aided numerical control CNC lathe.

Another aim of the preseny invention is to obtain an efficient position adjustment system that reduces the workload and processing times during measurement with different workpieces.

Detailed Description of the Invention

In this detailed description, the preferred embodiments of the inventive position adjustment system is described only for clarifying the subject matter in a manner such that no limiting effect is created.

The exemplary view of which is given in Figure 1, developed with the present invention comprises; position adjustment system, which comprises at least one holding element (1), preferably a lathe chuck, which ensures that at least one work piece is clamped and fixed, at least one movement element (2), preferably a chuck puller roller, which enables the holding element (1) to be moved, at least one sensing element (3), preferably a proximity or distance sensor, that detects the movement of the movement element (2) and/or the gripping or releasing the workpiece of the holding element (1), which provides processing on the workpiece, is suitable for use with at least one processing system, preferably computer aided numerical control (CNC) lathe, allows the physical position of the sensing element (3) to be adjusted by remote control; at least one body element (4), which is positioned on the processing system, close to the movement element (2), with at least one open surface and in a structure suitable for placing the elements of the position adjustment system therein, is preferably in the form of a rectangular chamber, ensures the protection of the elements placed therein. Further, it comprises at least one movement bearing (5) most preferably in the form of a linear channel or slot, which is located in the body element (4) and allows at least one moving part to be shifted on a linear axis; at least one shifting element (6) preferably in the form of a flat plate containing at least one connection socket, which is in a structure suitable to be placed in said movement bearing (5), enables said sensing element (3) to be attached thereon and enables the position of the sensing element (3) to be changed on a linear axis, Further, it comprises at least one closing element (7), preferably in the form of a flat plate, comprising at least one opening (7a) on its surface that extends to allow the movement of the sensing element (3) on the linear axis and enables the linear movement of the sensing element (3) to be limited within a distance, connected to the body element (4), ensuring that the open surface of the body element (4) is closed and that the elements inside the body element (4) are protected from external effects; at least one drive element (8), preferably a motor, associated with the shifting element (6), which enables the electrical energy to be converted into motion energy and the shifting element (6) to be moved in a linearly different direction.

In an exemplary embodiment of the position adjustment system developed with the present invention, the position adjustment system is connected to the processing system by means of the body element (4). After the sensing element (3) is passed through the opening (7a), it is connected with the shifting element (6) and the open surface of the body element (4) is closed by the closing element (7). Afterwards, the shifting element (6) is linearly shifted in two different directions within the movement bearing (5) by means of the drive element (7). In this way, in order to detect the movement of the movement element (2) and/or the gripping or releasing the workpiece of the holding element (1), the sensing element (3) is brought to the appropriate position before changing the physical position of the sensing element (3) and processing on workpieces with different diameters.

In a processing system where processing is applied to the workpiece, the physical position of the sensing element (3), which enables the compression of the workpiece to be detected and the system to be allowed to operate, is adjusted by remote control with the help of the position adjustment system developed with the present invention. In this way, before the user is processed on each workpiece of different diameter, a safe, practical and effective position adjustment system is obtained, which does not need to be entered into the processing system, provides user safety and reduces both the processing time and workload at the same time.
