Preferably, a spring is installed on the bottom of the second support frame, and a pulley is installed on one end of the spring, and there are two pulleys in total.

Preferably, a second threaded rod is installed on one side of the first support frame, and a nut is welded to one end of the second threaded rod.

Compared with the prior art, the beneficial effects of the utility model are:

(1) The utility model is equipped with a rotating platform and a workpiece fixing platform. After the workpiece is clamped by the workpiece fixing platform during use, when the user needs to process a certain position of the workpiece during the user's processing, the user rotates The angle of the workpiece fixing table is changed by loosening the first threaded rod. The user does not need to remove the entire workpiece and then change the angle, which solves the problem that the workpiece clamping part of the workpiece fixing device for the machine tool cannot drive the workpiece on the machine tool for angular rotation. The problem is that it is convenient for the user to adjust the installation angle of the workpiece on the machine tool, which is beneficial to the angle adjustment of the processing surface of the workpiece.

(2) The utility model is provided with a spring and a pulley. During use, when the user installs the workpiece fixing device for the machine tool on the guide rail on the machine tool, the distance between the first support frame and the second support frame decreases. , the spring and the pulley are compressed into the inside of the support frame, and the workpiece fixture for the machine tool cannot move on the guide rail of the machine tool. The user loosens the nut, and the spring pushes the pulley out of the support frame. At this time, the pulley is in contact with the guide rail of the machine tool, and the machine tool The workpiece fixing device can move on the guide rail of the machine tool, which solves the problem of inconvenient adjustment of the installation position of the workpiece fixing device for the machine tool, facilitates the rapid movement of the workpiece fixing device for the machine tool on the machine tool guide rail, and increases the workpiece fixing device for the machine tool on the machine tool on the installation location.

Detailed ways

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example. Based on the embodiments of the present utility model, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of the present utility model.

Please refer to Fig. 1-3, the utility model provides the following technical scheme: a kind of workpiece fixing device for machine tools, including the first support frame 2 and the second support frame 6, the top of the first support frame 2 is installed through the first threaded rod 3 There is a rotating platform 11, and a telescopic rod 5 is installed on one side of the rotating platform 11, and one end of the telescopic rod 5 is connected with a workpiece fixing table 4, which solves the problem that the workpiece clamping part of the workpiece fixing device for the machine tool cannot drive the workpiece on the machine tool Angle rotation problem, and the second clamping block 14 is welded on one side of the workpiece fixing platform 4, and the threaded platform 15 is welded on the other side.

Further, a third threaded rod 12 is installed on one side of the threaded table 15, and the threaded table 15 is connected with the third threaded rod 12 by screwing, and one end of the third threaded rod 12 is connected with the first clamping block 13, and the threaded table 15 is provided with an internal thread to facilitate the movement of the third threaded rod 12 , thereby facilitating the first clamping block 13 to approach the second clamping block 14 .

Further, a connecting rod 8 is welded on one side of the second support frame 6 , and an internal thread is provided inside the connecting rod 8 .

Specifically, a spring 7 is installed on the bottom of the second support frame 6, and a pulley 10 is installed on one end of the spring 7. There are two pulleys 10, which solves the problem that it is inconvenient to adjust the installation position of the workpiece fixing device for machine tools.

It is worth noting that a second threaded rod 9 is installed on one side of the first support frame 2, and one end of the second threaded rod 9 is welded with a nut 1, and the second threaded rod 9 is threadedly matched with the connecting rod 8, which is convenient for increasing and shortening The distance between the first support frame 2 and the second support frame 6 .
