[0014] Beneficial effects:

[0015] 1. This utility model features a side plate with a cylinder fixedly connected to one side. A first screw is movably connected to the inner side of each side plate via a U-shaped limiting hole. A base plate is threaded to the outer side of each first screw. Based on the workpiece size specifications during machining, the first screw is rotated counterclockwise to loosen it. Using the U-shaped limiting hole, the side plate and cylinder are moved to the desired position on the top of the base plate. Then, the first screw is rotated clockwise to fix the cylinder's position.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Please see Figure 1-6This utility model provides a technical solution: a machining auxiliary fixture, including a base plate 1, a driven clamping block 2 fixedly connected to one side of the top of the base plate 1, a first screw 3 threadedly connected to the inner side of the base plate 1, two first screws 3 symmetrically arranged, a side plate 5 movably connected to the outer side of each first screw 3 through a limiting hole 4, the limiting hole 4 being a U-shaped structure, a cylinder 6 fixedly connected to one side of each side plate 5, an active clamping block 10 fixedly connected to the output end of the cylinder 6, a slide bar 7 fixedly connected to the bottom of the cylinder 6, two slide bars 7 symmetrically arranged, a base plate 1 slidably connected to the outer side of each slide bar 7, a side frame 8 fixedly connected to one side of the base plate 1, a second screw 9 threadedly connected to the inner side of the side frame 8, two second screws 9 symmetrically arranged, which are rotated counterclockwise and released according to the size and specifications of the workpiece in machining. The first screw 3, in conjunction with the U-shaped limiting hole 4, moves the side plate 5 and the cylinder 6 to the desired position on the top of the base plate 1. Then, the first screw 3 is rotated clockwise to fix the position of the cylinder 6. Subsequently, the second screw 9 is rotated clockwise inside the side frame 8, causing the second screw 9 to move horizontally within the side frame 8 until one end of the second screw 9 fully abuts against the slide bar 7 to assist in fixing the cylinder 6. Finally, after the workpiece is placed between the driven clamping block 2 and the active clamping block 10, the cylinder 6 is opened for clamping. After processing is completed, the cylinder 6 is directly closed, causing the active clamping block 10 to move back, releasing the clamp and removing the workpiece. This effectively avoids the need for manual rotation of the screws in the fixture to clamp and release the workpiece, reducing the labor input during mass production.

[0029] In this utility model, preferably, a washer 13 is movably connected to the outer side of the top end of the first screw 3, and a base plate 1 is threadedly connected to the outer side of the first screw 3, which can effectively reduce the loosening range of the first screw 3 during long-term use. A bracket 15 is fixedly connected to one side of the side frame 8, and several brackets 15 are symmetrically arranged. Each bracket 15 has a triangular structure, and a base plate 1 is fixedly connected to one side of each bracket 15, which can effectively ensure the stability of the side frame 8. An adapter piece 11 is fixedly connected to the other side of the base plate 1, and several adapter pieces 11 are symmetrically arranged. Each adapter piece 11 has a screw hole on its inner side, which can be used to further fix the device with the screw added to the workbench.

[0030] In this utility model, preferably, a clamping pad 12 is fixedly connected to one side of both the driven clamping block 2 and the active clamping block 10. The clamping pad 12 is made of flexible material and has a serrated structure on one side, which can effectively reduce the wear of the workpiece during the clamping process. A scale 14 is fixedly connected to one side of the top of the base plate 1. Two scales 14 are symmetrically arranged and are located on one side of the side plate 5, which can effectively mark the position of the side plate 5 and the cylinder 6 and the sliding stroke. The slide bars 7 are all T-shaped structures, and the top of each slide bar 7 is fixedly connected to the cylinder 6, which can effectively reduce the swing amplitude. A spring 16 is movably connected to the outer side of one end of the second screw 9. The spring 16 is located on one side of the side frame 8, which can effectively ensure the stability of the second screw 9 during use.

[0031] The working principle and usage process of this utility model are as follows: During use, according to the workpiece size specifications in machining, the first screw 3 is rotated counterclockwise and loosened. Using the U-shaped limiting hole 4, the side plate 5 and cylinder 6 are moved to the desired position on the top of the base plate 1. Then, the first screw 3 is rotated clockwise to fix the position of the cylinder 6. Next, inside the side frame 8, the second screw 9 is rotated clockwise, causing it to move horizontally within the side frame 8 until one end of the second screw 9 fully abuts against the slide bar 7 to assist in fixing the cylinder 6. Finally, the workpiece is placed between the driven clamping block 2 and the active clamping block 10, and the cylinder 6 is opened for clamping. After machining is completed, the cylinder 6 is directly closed, causing the active clamping block 10 to move back, loosening the clamp, and removing the workpiece. This effectively avoids the need for manual rotation of the screws in the fixture to clamp and loosen the workpiece, reducing labor input during mass production.
