Modern enterprises use the principles and methods of systems engineering to organize production and guide production, and regard the production process as a production system with inputs and outputs, which is called machining. Machining refers to the process of changing the shape, size or performance of a workpiece through a mechanical device. According to the differences in processing methods, it can be divided into cutting processing and pressure processing. When machining workpieces of various irregular shapes, it is necessary to first clamp and fix the workpiece, and at this time, a fixture is needed.

[0003] Patent Application No. CN219747089U discloses a fixture for machining that is convenient for adjusting dimensions, including a workbench. A chute is provided inside the workbench, and a first support frame is slidably connected to the inner wall of the chute. A motor is fixedly connected to the upper surface of the first support frame, and a threaded rod is fixedly connected to the output end of the motor. A fixed block is slidably connected to the outer wall of the threaded rod. In this utility model, first, by starting the motor, the threaded rod is driven by the output end of the motor to rotate inside the first support frame, so as to achieve the effect that the fixed block moves up and down on the outer wall of the threaded rod. Then, the output end of the hydraulic rod drives the clamping block to cooperate with the fixing plate, so as to achieve the effect of clamping the workpiece to be machined. Then, the output end of the cylinder pushes the first support frame, so that the slider fixed to the lower surface of the first support frame slides on the inner wall of the chute, so as to achieve the effect of further clamping the workpiece to be machined.

[0004] In the above patent, although the adjustment of the fixture can be completed, each fixture cannot be adjusted individually, only overall adjustment can be performed, and each individual clamping seat cannot be adjusted according to different mechanical parts, which has certain limitations. Those skilled in the art provide a fixture for machining that is convenient for adjustment to solve the problems raised in the above background art. Summary of the Utility Model

[0005] To solve the problems raised in the above background art, this application provides a fixture for machining that is convenient for adjustment.

[0006] The fixture for machining that is convenient for adjustment provided by this application adopts the following technical solutions:

[0007] A fixture for machining that is convenient for adjustment, including a workbench. Four clamping components are fixedly installed annularly at the upper end of the workbench. One clamping component includes a clamping seat. One end of the clamping seat is fixedly installed with a rubber contact plate. The lower end of the clamping seat is fixedly installed with a T-shaped plate. A number of balls are movably embedded near both sides at the lower end of the T-shaped plate. The lower end of the T-shaped plate is fixedly installed with a semi-circular arc plate, and a threaded groove is opened on the inner wall of the semi-circular arc plate. A threaded column is arranged inside the semi-circular arc plate.

[0008] Preferably, a circular hole is opened near the center at the upper end of the workbench. Four T-shaped grooves are opened at the upper end of the workbench, and a semi-circular groove is opened at the bottom end inside the T-shaped groove.

[0009] Preferably, sliding grooves are opened near both sides inside the T-shaped groove. The T-shaped plate is in snap-fit with the T-shaped groove, and the balls are in sliding fit with the sliding grooves.

[0010] Preferably, one end of the T-shaped groove and the semi-circular groove extends into the circular hole, and the other end of the T-shaped groove and the semi-circular groove extends to the outside of the workbench.

[0011] Preferably, a sleeve is fixedly installed inside the workbench. The sleeve is movably connected to one end of the threaded column, and a rotating head is fixedly installed at the other end of the threaded column. The rotating head is located outside the workbench.

[0012] Preferably, the threaded column is in threaded connection with the threaded groove, and the threaded column is located inside the semi-circular groove.

[0013] In summary, the present application includes the following beneficial technical effects: Through the four independent clamping components provided, the clamping components move towards the circular hole of the workbench to fix the workpiece by clamping. When the rotating head is rotated to make the threaded column rotate, since the position of the threaded column is fixed, the semi-circular arc plate is driven to move, so that the clamping seat moves towards the circular hole, and the rubber contact plate contacts the workpiece for clamping. The rubber contact plate increases the friction between the workpiece and the clamping seat, which is convenient for clamping the workpiece. And the four clamping seats are independently arranged, so that by rotating one rotating head alone and moving one clamping seat, the clamping is more flexible and the controllability is stronger.

Specific implementation mode

[0018] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific implementation modes.

[0019] As Figures 1-3 shown, a fixture for machining that is easy to adjust includes a workbench 1. Four clamping assemblies 3 are fixedly installed annularly at the upper end of the workbench 1. One clamping assembly 3 includes a clamping seat 7. One end of the clamping seat 7 is fixedly installed with a rubber contact plate 8. The lower end of the clamping seat 7 is fixedly installed with a T-shaped plate 9. A number of balls 10 are movably embedded near both sides at the lower end of the T-shaped plate 9. The lower end of the T-shaped plate 9 is fixedly installed with a semi-circular arc plate 11. A threaded groove 12 is provided on the inner wall of the semi-circular arc plate 11. A threaded column 14 is arranged inside the semi-circular arc plate 11.

[0020] First, place the workpiece on the workbench 1. Through the four independent clamping assemblies 3 provided, the clamping assemblies 3 move towards the round hole 2 of the workbench 1 to fix the workpiece by clamping. Rotate the rotating head 15 to make the threaded column 14 rotate. Since the position of the threaded column 14 is fixed, the semi-circular arc plate 11 is driven to move, so that the clamping seat 7 moves towards the round hole 2, and the rubber contact plate 8 contacts the workpiece to clamp it. The rubber contact plate 8 increases the friction between the workpiece and the clamping seat 7, which is convenient for clamping the workpiece. And the four clamping seats 7 are independently arranged, so that by rotating one rotating head 15 alone, one clamping seat 7 can be moved, making the clamping more flexible and the controllability stronger.

[0021] In this embodiment, a round hole 2 is opened near the center at the upper end of the workbench 1. Four T-shaped grooves 4 are opened at the upper end of the workbench 1. And a semi-circular groove 6 is opened at the inner bottom end of the T-shaped groove 4.

[0022] In this embodiment, sliding grooves 5 are opened near both sides inside the T-shaped groove 4. The T-shaped plate 9 is in snap-fit with the T-shaped groove 4, and the balls 10 are in sliding fit with the sliding grooves 5.

[0023] The balls 10 reduce the friction between the T-shaped plate 9 and the T-shaped groove 4, making the movement of the clamping seat 7 smoother.

[0024] In this embodiment, one end of the T-shaped groove 4 and the semi-circular groove 6 extends into the interior of the circular hole 2, and the other end of the T-shaped groove 4 and the semi-circular groove 6 extends to the outside of the workbench 1.

[0025] In this embodiment, a sleeve 13 is fixedly installed inside the workbench 1. The sleeve 13 is movably connected to one end of the threaded column 14, and a rotating head 15 is fixedly installed at the other end of the threaded column 14. The rotating head 15 is located outside the workbench 1.

[0026] In this embodiment, the threaded column 14 is in threaded connection with the threaded groove 12, and the threaded column 14 is located inside the semi-circular groove 6.

[0027] The implementation principle of a clamp for machining that is easy to adjust in the embodiment of the present application is as follows: First, place the workpiece on the workbench 1. Through the four independent clamping components 3 provided, the clamping components 3 move towards the circular hole 2 of the workbench 1 to fix the workpiece by clamping. Rotate the rotating head 15 to make the threaded column 14 rotate. Since the position of the threaded column 14 is fixed, the semi-circular arc plate 11 is driven to move, so that the clamping seat 7 moves towards the circular hole 2, and the rubber contact plate 8 contacts the workpiece for clamping. The rubber contact plate 8 increases the friction between the workpiece and the clamping seat 7, facilitating clamping of the workpiece. Moreover, the four clamping seats 7 are independently arranged, so that by rotating one rotating head 15 alone, one clamping seat 7 can be moved, making the clamping more flexible and the controllability stronger.
