Title:
COOLING MEDIUM INJECTION DEVICE
Document Type and Number:
WIPO Patent Application WO/2023/021754
Kind Code:
A1
Abstract:
[Problem] To provide a cooling medium injection device for raising the pressure of a cooling medium supplied from a main shaft of a machine tool. [Solution] In the present invention, a rotating part of a pump 200 is linked to a body member 110. In a state in which the body member 110 is attached to a main shaft 20 of a machine tool 10, a detent pin 310 of a detent device 300 is fitted into a fitting hole 41 in the machine tool 10 and is in contact with a wall surface 41a of the fitting hole 41. The detent pin 310 and a detent lever 340 move toward one axial-direction side against the elastic force of a spring 320, and the detent lever 340 and an engagement hole 113 provided to the body member 110 are disengaged from one another. This results in a support part (cover 150 and case 160) being secured to the machine tool 10 and impedes rotation of the support part about the body member 110. Rotation of the body member 110 relative to the support part is also enabled. A force detection sensor 50 outputs a force detection signal indicating the force with which the wall surface 41a is pressed by the pin 310.
