[0003] At present, the existing tooling fixtures on the market can usually only clamp one of the rectangular workpieces or cylindrical workpieces when in use. If a fixture for clamping rectangular workpieces is used to clamp a cylindrical workpiece, it is easy to cause skewness. Conversely, using a fixture for clamping cylindrical workpieces to clamp a rectangular workpiece will also cause skewness. Utility Model Content

[0004] The purpose of the present invention is to provide a position limiting fixture for machining that prevents deflection, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A base, a clamping platform is provided at the middle of the top of the base, a clamping plate is symmetrically provided on both sides of the top of the clamping platform, and a clamping mechanism is provided between the two clamping plates and the base and the clamping platform;

[0008] Side frames are provided on opposite sides of the two first clamping plates, and a second clamping mechanism is provided in the middle of the side frames.

[0009] Preferably, the clamping mechanism includes a guide groove, which is opened on both sides of the middle of the base and the clamping platform, and a bidirectional screw is provided between the inner and lower parts of the two guide grooves. A motor is provided on the right side of the base, and the output shaft of the motor is fixedly connected to the bidirectional screw.

[0013] Preferably, a chute is provided in the middle of the first clamping plate, and a slider slidably connected to the chute is provided on one side of the second clamping plate.

[0014] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0015] For the anti-skew mechanical processing limiting tooling fixture, through the cooperation of the first clamping plate, the second clamping plate and the clamping table, when the device is in use, a rectangular workpiece can be clamped by the first clamping plate and the second clamping plate, or a cylindrical workpiece can be clamped according to the V-shaped inner groove formed by the first clamping plate and the second clamping plate, thereby improving the application range of the fixture.

[0016] For the anti-skew mechanical processing limiting tooling fixture, the device is provided with a second clamping plate on one side of the first clamping plate, and the first clamping plate and the second clamping plate are set at a right angle to form a V-shaped inner groove therebetween. By clamping the cylindrical workpiece in the two V-shaped inner grooves, the contact points become the contact lines between the two sides and the cylindrical surface. Due to the increased contact area and more uniform distribution of contact stress, the clamping stability is higher. Description of the Drawings

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] Such as Figures 1-4As shown in the figure, a technical solution provided by the present utility model is as follows:

[0024] A limit fixture for mechanical processing to prevent skew, including a bottom table 1. In the middle of the top of the bottom table 1, there is a clamping table 2. On both sides of the top of the clamping table 2, there are symmetrically arranged first clamping plates 3. Between the two first clamping plates 3 and the bottom table 1 and the clamping table 2, there is a first clamping mechanism. The first clamping mechanism includes a guide groove 5. The guide groove 5 is opened on both sides of the middle parts of the bottom table 1 and the clamping table 2. Between the lower parts of the two guide grooves 5, there is a bidirectional screw 6. On the outside of the right side of the bottom table 1, there is a motor 7. The output shaft of the motor 7 is fixedly connected to the bidirectional screw 6. The two ends of the bidirectional screw 6 are respectively movably installed with movable blocks 8. On the top of the two movable blocks 8, there is further provided a second cylinder 9. The output shaft of the second cylinder 9 is fixedly connected to the first clamping plate 3 through a base 10. The base 10 is slidably connected to the guide groove 5. On the opposite sides of the two first clamping plates 3, there are side frames 4. In the middle of the side frames 4, there is a second clamping mechanism. The second clamping mechanism includes a first cylinder 11. The first cylinder 11 is arranged on the outside of the middle part of the side frame 4. The output shaft of the first cylinder 11 passes through the side frame 4 and is fixedly installed with a second clamping plate 12. The second clamping plate 12 is perpendicular to the first clamping plate 3. In the middle of the first clamping plate 3, there is a chute 13. On one side of the second clamping plate 12, there is a slider 14 slidably connected to the chute 13;

[0025] In this embodiment, when the device is in use, a rectangular workpiece can be clamped by the first clamping plate 3 and the second clamping plate 12, and the device can be adaptively adjusted according to the height and area of the workpiece, so as to improve the application range of the fixture. When adjusting, start the second cylinder 9. The second cylinder 9 drives the base 10 to lift the first clamping plate 3. When the first clamping plate 3 is lifted, the second clamping plate 12 on the same side moves synchronously, and thus the device can be adapted according to the thickness of the workpiece. Then, according to the area of the workpiece, the position of the second clamping plate 12 is adjusted. When adjusting, start the first cylinder 11. The first cylinder 11 drives the second clamping plate 12 on the front of the side frame 4 to move linearly;

[0026] At the same time, a cylindrical workpiece can also be clamped according to the V-shaped inner groove formed by the first clamping plate 3 and the second clamping plate 12. The device is provided with the second clamping plate 12 on one side of the first clamping plate 3, and the first clamping plate 3 and the second clamping plate 12 are set at a right angle, forming a V-shaped inner groove between them. By clamping the cylindrical workpiece in the two V-shaped inner grooves, the contact points become the contact lines between two sides and the cylindrical surface. Because the contact area increases and the contact stress distribution is more uniform, the clamping stability is higher.

[0027] Working principle: When clamping a rectangular workpiece, adjust the height of the first clamping plate 3 according to the thickness of the rectangular workpiece. When adjusting, start the second cylinder 9, and the second cylinder 9 drives the base 10 to lift the first clamping plate 3. When the first clamping plate 3 is lifted, it moves synchronously with the second clamping plate 12 on one side, so that it can be adapted according to the thickness of the workpiece. Then, adjust the position of the second clamping plate 12 according to the area of the workpiece. When adjusting, start the first cylinder 11, and the first cylinder 11 drives the second clamping plate 12 on the front of the side frame 4 to move linearly. After the adjustment is completed, start the motor 7, and the motor 7 drives the bidirectional screw 6 to rotate. When the bidirectional screw 6 rotates, it drives the two movable blocks 8 to move towards each other, and then clamps the rectangular workpiece through the first clamping plate 3 and the second clamping plate 12. A second clamping plate 12 is arranged on one side of the first clamping plate 3 of this device, and the first clamping plate 3 and the second clamping plate 12 are arranged at a right angle, forming a V-shaped inner groove between them. By clamping the cylindrical workpiece in the two V-shaped inner grooves, the contact points become the contact lines between the two sides and the cylindrical surface. Because the contact area increases and the contact stress distribution is more uniform, the clamping stability is higher.
