Description

Tool change driving apparatus of synchronous cutting machine

The present invention relates to the field of synchronous cutting machine technology, and more particularly, the tool exchange of the synchronous cutting machine that can be applied to the cutting unit of various models by elastically responding to the size, as well as can be more easily manufactured and assembled It relates to a drive device.

A conventional synchronous cutting machine, as disclosed in the Taiwan Patent No. M541922 patent, first drives the spindle unit and raises it by a certain distance when changing the tool so that the cutting unit installed in the spindle unit is also raised accordingly. The clamping part is clamped into the clamping recess of the drive part of the tool change drive installed in the tool change unit. At this time, the drive motor of the tool change drive device rotates the cam box drive gear coupled to the shaft lever end in association with the shaft lever, and furthermore, in conjunction with the cam box to rotate the tool change arm to the bottom of the gripper set; At the same time, the shaft lever also rotates in conjunction with the tool release drive gear and the tool release gear, and then through the two intermeshing bevel gears to drive and rotate the drive component coupled to the tool release output shaft and the tool release output shaft, This causes the driven clamping part and the cam part to rotate, and finally, the tool release arm is pushed into the cam part to rotate, causing the machining tool to disengage from the gripper set by interlocking, furthermore, the tool changer arm changes the tool for the machining tool. Allow the task to run.

In order for the power of the drive motor to be smoothly transmitted to the cam part, the driven clamping part and the drive part must be clamped to each other exactly in the coaxial state, and there should be no deviation or eccentricity. However, there are minute differences in both dimensions and sizes of various types of cutting units, and these minute differences often cause problems in that the driving parts and the driven clamping parts are not exactly coaxially clamped to each other. In addition, fine tolerances exist during the manufacturing of each of the accessories of the tool change unit and the tool change unit, and these tolerances frequently cause the problem that the driving parts and the driven clamping parts are not accurately coaxially clamped after assembly is completed. Will result.

Since the tool change driving device of the conventional synchronous cutting machine transmits the rotational power of the shaft lever to the tool release output shaft by using the connection of the gear set, the structure of the gear set includes a shaft lever coaxially connected to the rotation shaft of the drive motor, The tool release drive gear coupled to the shaft lever, the tool release gear meshed with the tool release drive gear, the drive bevel gear coaxially coupled with the tool release gear, and the driven bevel gear engaged with the drive bevel gear and coupled to the tool release output shaft It is configured to include.

Accordingly, the distance between the shaft lever and the tool release output shaft and the height of the tool release output shaft are both fixed to be unadjustable. Therefore, not only can not be applied to various types of cutting units, but also due to manufacturing tolerances suffer a lot of trouble and difficulty during assembly.
