Document Type and Number:
WIPO Patent Application WO/2018/039892
Kind Code:
A1
Abstract:
Disclosed is a movable centre dedicated for an engraving machine, comprising a movable shaft (2), a central movable shaft (10), an outer sleeve (3), a movable centre (5) and a hand wheel (12). The movable centre (5) is sleeved on an outer side of a shaft shoulder end of the movable shaft (2). An external thread end of the central movable shaft (10) is screwed in from the other end of the movable shaft (2), and the other end of the central movable shaft (10) is fixedly connected to an end surface of the hand wheel (12). The outer sleeve (3) is sleeved on an outer side of the movable shaft (2). A linear bearing (1) is provided between the outer sleeve (3) and the movable shaft (2). An end of the outer sleeve (3), which is close to the movable centre (5), is provided with a locking cover (9), and the other end thereof is provided with a locking nut (4). The locking cover (9) and the locking nut (4) are used for locking the movable centre dedicated for an engraving machine on the engraving machine. The device uses the linear bearing to connect the movable shaft and the outer sleeve, which eliminates a gap between the two; and a locking screw locks from the end surface of the hand wheel, so that the locking effect is firmer and safer.
