Description

Technical Field

[0001] This utility model relates to the field of machine tool equipment technology, specifically to a fixture for CNC machine tools. Background Technology

[0002] A machine tool fixture is a device used on a machine tool to clamp workpieces and guide cutting tools. Its main function is to determine the correct position of the workpiece in the fixture so as to ensure the correct relative position of the workpiece with respect to the cutting tool and the machining motion of the machine tool during processing.

[0003] The existing fixtures for CNC machine tools have a relatively fixed structure, which severely limits the angle of rotation they can rotate during use. This not only affects the flexibility of the fixtures but also limits their application potential when processing parts with complex shapes or requiring multi-angle machining. Utility Model Content

[0004] To address the aforementioned problems, this invention provides a fixture for CNC machine tools. It avoids the issue that existing CNC machine tool fixtures have relatively fixed structures, which severely limit their rotation angles during use. This not only affects the fixture's flexibility but also restricts its application potential when processing parts with complex shapes or requiring multi-angle machining.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is as follows: a fixture for CNC machine tools, including a platform, an adjustment device is provided inside the platform, an electric push rod one and an electric push rod two are respectively fixed on the upper part of the adjustment device, a fixed box is fixed on the upper end of the electric push rod one, a rotating device one is fixed on one side inside the fixed box, a rotating device two is fixed on the upper end of the electric push rod two, and a clamping device is provided inside both the rotating device one and the rotating device two;

[0006] The clamping device includes a bidirectional motor II fixed inside the rotating device I and the rotating device II. Both output ends of the bidirectional motor II are connected to screws II, and both screws II are connected through clamping plates.

[0007] As an improvement, the clamping plate is provided with a threaded hole on the side near the second screw, and the clamping plate is threadedly connected to the second screw.

[0008] As an improvement, the adjustment device includes a bidirectional motor fixed inside the platform, with a screw connected to each of the two output ends of the bidirectional motor, and a moving block connected through the screw.

[0009] As an improvement, the movable block is provided with a threaded hole inside, and the movable block is threadedly connected to the screw.

[0010] As an improvement, the rotating device includes a drive motor fixed inside a fixed box, the output end of the drive motor is connected to a rotating shaft, and a connecting box is fixed to the top of the rotating shaft.

[0011] As an improvement, the rotating device 2 includes a drive motor 2 fixed to the upper end of the electric push rod 2, the output end of the drive motor 2 is connected to a rotating shaft 2, and a connecting box 2 is fixed to the end of the rotating shaft 2.

[0012] The advantages of this utility model compared with the prior art are as follows: after the parts are fixed by the clamping device, the parts can be adjusted on the horizontal and vertical planes by the rotating device one and the rotating device two. This avoids the problem that the structure of the existing CNC machine tool fixtures is relatively fixed, which leads to a strict limitation on the angle of rotation during use. This not only affects the flexibility of the fixture, but also limits its application potential when dealing with complex shapes or parts that require multi-angle machining.
