Abstract

[0002] A fixture is a device used to fix the processing object in the mechanical manufacturing process so that it occupies the correct position for construction or inspection. Its main purpose is to ensure the stability and accuracy of the workpiece product during processing, inspection or assembly, thereby improving production efficiency and product quality.
[0003] However, current clamps have great limitations and can only fix specific products. When processing irregular products of different heights, the clamps cannot adapt well to the irregularities and height changes of the products, resulting in the clamps being unable to clamp the product at the appropriate position on the surface, which may cause the product to shake or tilt during processing, making it difficult to firmly clamp the product. When the clamps are clamping irregularly shaped products, the clamps cannot effectively contact certain irregular parts of the product, which will result in the clamps not being able to fully fit the shape of the product, causing excessive local pressure during the clamping process, which in turn causes indentations on the product surface.

[0023] In this embodiment, the screw rod 6 rotates and cooperates with the thread between the connecting block 7, and then drives the connecting block 7 to rise and fall and slide on the inner wall of the limiting groove 5. While sliding, the connecting block 7 will drive the support frame 8 to rise and fall synchronously. When the support frame 8 is adjusted to a suitable height, the telescopic cylinder 10 can be used to push the clamping plate 14 to clamp and fix the product. By adjusting the height of the support frame 8, the clamping plate 14 can be clamped at a suitable position of the product, so that the clamp can maintain the correct position during the clamping process of the product, thereby improving the scope of application of the clamp.
[0024] like Figure 3 and Figure 4 As shown, a plurality of extrusion strips 15 are provided on one side of the clamping plate 14, and two hinge seats 16 are symmetrically fixedly connected on the other side of the clamping plate 14, the inner walls of the two hinge seats 16 are hinged with hinge blocks 17, the ends of the hinge blocks 17 are fixedly connected with support springs 18, one ends of the support springs 18 are fixedly connected with hinge blocks 19, the ends of the hinge blocks 19 are hinged with hinge seats 20, and the outer sides of the hinge seats 20 are fixedly connected to the outer wall of the connecting plate 11.

When the angle of the clamping plate 14 changes, one of the support springs 18 will be compressed and the other support spring 18 will be stretched and expanded. When the clamping plate 14 loses contact with the product, the elasticity of the support spring 18 can drive the clamping plate 14 to quickly restore the initial angle.

The bottom end of the connecting frame 26 is slidably connected to the inner wall of one of the limit seats 23, and the top end of the connecting frame 26 is fixedly connected to the bottom end of the support block 4.
[0029] In this embodiment, when one of the racks 25 moves, it meshes with the rotating gear 24, causing the rotating gear 24 to rotate, and then drives the other rack 25 to move synchronously, so that the two racks 25 move in relative directions. While the two racks 25 move, they will drive the two support blocks 4 through the connecting frame 26 to move synchronously in relative directions, so that the distance between the two clamping plates 14 can be adjusted, so that products of different sizes can be clamped.
[0030] like Figure 5 As shown, a holder 27 is fixedly connected to the outer side of the base 1, a drive motor 28 is fixedly installed on the inner side of the holder 27, the end of the output shaft of the drive motor 28 passes through the interior of the mounting cavity 2 and is fixedly connected to a screw rod 29, and one end of the screw rod 29 is rotatably connected to the inner wall of the mounting cavity 2, the outer wall of the screw rod 29 is threadedly connected to a sleeve 30, and one side of the sleeve 30 is fixedly connected to the outer wall of one of the racks 25.

[0033] In this embodiment, the screw rod 6 can be driven to rotate by rotating the knob 31, and then the clamping height of the clamping plate 14 can be controlled and adjusted by the threaded engagement between the screw rod 6 and the connecting block 7 when the screw rod 6 rotates.
[0034] In summary, the working principle of the utility model is as follows:
[0035] When in use, first, when clamping products of different sizes, the lead screw 29 is driven to rotate by the driving motor 28, so that the lead screw 29 is threadedly matched with the sleeve 30 when rotating, so that the sleeve 30 moves, and while the sleeve 30 moves, one of the racks 25 can be moved, and then the moving rack 25 is meshed with the rotating gear 24, so that the rotating gear 24 rotates, and then drives the other rack 25 to move synchronously, so that the two racks 25 move in relative directions. While the two racks 25 move, they will drive the two support blocks 4 through the connecting frame 26 to move synchronously in relative directions, so that the distance between the two clamping plates 14 can be adjusted, so that products of different sizes or different heights can be clamped. When the clamp clamps products of different sizes or heights, the lead screw 6 can be driven to rotate by rotating the knob 31. When the lead screw 6 rotates, it is threadedly matched with the connecting block 7, and then the connecting block 7 is driven to lift and slide on the inner wall of the limiting groove 5. The connecting block 7 slides At the same time, it will drive the support frame 8 to rise and fall synchronously. When the support frame 8 is adjusted to a suitable height, the clamping plate 14 can be pushed by the telescopic cylinder 10 to clamp and fix the product. By adjusting the height of the support frame 8, the clamping plate 14 can be clamped at a suitable position of the product, so that the fixture can maintain the correct position during the clamping process of the product, thereby improving the application range of the fixture. The clamping plate 14 is hinged between the hinge 12 and the hinge 2 13, and then the clamping plate 14 changes its angle according to the inclined surface of the product, so as to adapt to workpieces of different shapes and provide a stable and uniform clamping force, thereby preventing the fixture from having excessive local pressure during the clamping process, resulting in indentations on the product surface. When the clamping plate 14 changes its angle, one of the support springs 18 will be compressed by force, while the other support spring 18 will be stretched and expanded by force. When the clamping plate 14 is out of contact with the product, the elasticity of the support spring 18 can drive the clamping plate 14 to quickly restore its initial angle.
