[0003] At present, the commonly used vise fixtures on the market, although widely used, have a limited clamping stroke. When machining different features of a product, it is often necessary to reposition the vise, which not only reduces the machining efficiency but also may affect the machining accuracy. Therefore, how to improve the machining efficiency while ensuring the machining accuracy and reducing the number of times the fixture is repositioned has become a technical problem to be solved in this field.

[0004] In view of the above related technologies, the existing vise fixtures need to use additional measuring tools to confirm the clamping position during positioning, which increases the clamping preparation time, is not conducive to quickly and efficiently completing the machining task, and reduces the product machining efficiency. Therefore, developing a fixture that can quickly and accurately adjust the clamping position while reducing the use time of measuring tools has become the key to improving machining efficiency.

In addition, by providing the clamping plates 24, it is possible to adapt to clamping products of different heights, with a wide range of applications and ensuring the stability of product clamping. Flexible pads 241 are provided on the sides of the two clamping plates 24 close to each other, and the flexible pads 241 are fixedly bonded to the clamping plates 24.

[0045] Referring to Figure 2 and Figure 4 , a machining fixture further includes a fixing assembly 3, and the fixing assembly 3 is arranged on the clamping assembly 2.

[0046] Referring to Figure 4, the fixing component 3 includes two fixing members 31 and two inserting members 32. The clamping seats 21 correspond to the fixing members 31 one by one. An accommodating groove 211 for inserting the clamping plate 24 is formed at the top of the clamping seat 21. The fixing member 31 includes two fixing plates 311 and at least two first springs 312. The two fixing plates 311 are located in the accommodating groove 211, and the two fixing plates 311 are respectively close to two opposite groove walls of the accommodating groove 211. The fixing plates 311 are slidably connected to the clamping seat 21. The two fixing plates 311 can move towards or away from each other. The two fixing plates 311 can fix the clamping plate 24. In this embodiment, there are four first springs 312. One fixing plate 311 corresponds to two first springs 312. The two first springs 312 are both located on the side where the two fixing plates 311 are away from each other. The two first springs 312 are arranged in parallel and are arranged along the length direction of the sliding groove 1211. One end of the first spring 312 is welded to the fixing plate 311, and the other end is welded to the clamping seat 21. In this embodiment, the first spring 312 is a compression spring.

When the clamping plate 24 is inserted into the accommodating groove 211, the positioning hole 242 corresponds to the sliding hole 212. The second spring 322 is sleeved on one end of the pull rod 321 located outside the clamping seat 21. One end of the second spring 322 is welded to the clamping seat 21, and the other end is welded to the pull rod 321. In this embodiment, the second spring 322 is a tension spring. When it is necessary to insert the clamping plate 24 into the accommodating groove 211, a person pulls the pull rod 321. At this time, the second spring 322 is stretched and has elastic potential energy. After the clamping plate 24 is inserted into the accommodating groove 211, the person releases the pull rod 321, and the spring restores its deformation. The pull rod 321 passes through the sliding hole 212 and the positioning hole 242, and can fix the clamping seat 21 and the clamping plate 24.

[0048] The implementation principle of Embodiment 1 is as follows: When it is necessary to use a machining fixture to clamp a product, the machining fixture is placed on the operating table in advance and fixed to the operating table. Subsequently, according to the size of the product to be clamped, when the clamped product is relatively low, the operator takes out the screwing member in the clamping assembly 2, connects the screwing member to the driving member 22, starts the screwing member, the screwing member drives the screw 221 to rotate, and the screw 221 can drive the clamping seat 21 to move. According to the above steps, the movement of the other clamping seat 21 can be adjusted. When the clamping seat 21 is adjusted to the appropriate position, the operator connects the screwing member to the driving member 22 again, which can drive the screw 221 to rotate, and can make the two clamping seats 21 clamp the product.

[0049] When the clamped product is relatively high, the operator takes out the clamping plate 24, makes the clamping plate 24 correspond to the clamping seat 21, the operator pulls the pull rod 321, inserts one side of the clamping plate 24 into the receiving groove 211. At this time, the two fixing plates 311 can fix the clamping plate 24. Subsequently, the pull rod 321 is released. The pull rod 321 passes through the clamping seat 21 and the clamping plate 24 in sequence, and the pull rod 321 fixes the clamping seat 21 and the clamping plate 24. Then, according to the above steps, by connecting the screwing member to the driving member 22, the position of the clamping seat 21 can be adjusted, and the clamping plate 24 moves synchronously with the clamping seat 21, so as to clamp the product.

[0050] Embodiment 2

The rotating member 25 includes two screwing handles 251, and the screwing handles 251 correspond to the screws 221 one by one. The screwing handles 251 are welded to the end of the screw 221 away from the partition plate 122. When it is necessary to rotate the screw 221, the operator only needs to rotate the screwing handle 251. Since the screwing handle 251 is welded to the rotating seat 223, there is no need for multiple connections, which is convenient for improving the clamping efficiency.

[0052] The implementation principle of Embodiment 2 is as follows: When it is necessary to clamp a product, first, the position of the clamping seat 21 is adjusted according to the size of the product. The operator only needs to rotate the screwing handle 251, which is convenient for driving the screw 221 to rotate, so as to adjust the position of the clamping seat 21.

[0053] The above are all the preferred embodiments of this application. The protection scope of this application is not limited accordingly.
