[0036] As Figures 1-6 shown, a machining fixture with a straightening function includes: a base frame 100, a clamping assembly 200, and a straightening assembly 300.

[0037] Among them, the number of the clamping assemblies 200 is at least two. The clamping assemblies 200 are distributed around the base frame 100, and the clamping assemblies 200 form an enclosing structure and form a straightening space.

[0038] Specifically, the clamping assembly 200 can clamp the side of the workpiece.

[0039] Wherein, the straightening assembly 300 is located in the straightening space, the number of the straightening assemblies 300 is at least two, and the straightening assemblies 300 are arranged in sequence along the straightening direction. One straightening assembly 300 includes a straightening driving element and two straightening blocks 330. The straightening driving element is connected to the base frame 100, and both of the two straightening blocks 330 are connected to the straightening driving element. The straightening driving element can simultaneously drive the two straightening blocks 330 to approach or move away from each other, and the moving directions of the two straightening blocks 330 are perpendicular to the straightening direction.

[0040] Specifically, the straightening assembly 300 can clamp the middle part of the workpiece.

[0041] In this embodiment, the straightening assemblies 300 are arranged in sequence along the straightening direction, and the straightening driving element is used to simultaneously drive the two straightening blocks 330 to approach or move away from each other along the direction perpendicular to the straightening direction, so that the distribution direction of the middle part of the workpiece is as close as possible to the straightening direction, and the straightening of each part of the middle part of the workpiece is realized.

[0042] As Figures 1-6 shown, on the basis of the above embodiment, the straightening driving element includes a driving seat 310 and a driving block 320. The driving seat 310 is connected to the base frame 100. The straightening block 330 is movably connected to the driving seat 310, and the driving block 320 is liftably connected to the driving seat 310. The driving block 320 is provided with a linkage portion 321, and the straightening block 330 is provided with a linkage groove 331. The linkage portion 321 is located in the linkage groove 331 and can move along the linkage groove 331. When the driving block 320 moves up and down, it moves relative to the linkage groove 331 through the linkage portion 321 and drives the two straightening blocks 330 to approach or move away from each other.

[0043] In this embodiment, when the driving block 320 moves up and down, it moves relative to the linkage groove 331 through the linkage portion 321 and drives the two straightening blocks 330 to approach or move away from each other, so that the effect of "one driving two" can be easily realized.

[0044] As Figures 1-6 shown, on the basis of the above embodiment, the driving seat 310 is provided with a driving cavity. The driving block 320 passes through the driving seat 310 and forms a partition portion 322. The partition portion 322 is located in the driving cavity and divides the driving cavity into a first chamber 311 and a second chamber 312. The first chamber 311 is provided with a first external connection channel 3111, and the second chamber 312 is provided with a second external connection channel 3121.

[0045] When the medium in the first external channel 3111 moves towards the first chamber 311 and the medium in the second chamber 312 moves towards the second external channel 3121, the partition 322 drives the driving block 320 to move in the direction from the first chamber 311 towards the second chamber 312.

[0046] When the medium in the second external channel 3121 moves towards the second chamber 312 and the medium in the first chamber 311 moves towards the first external channel 3111, the partition 322 drives the driving block 320 to move in the direction from the second chamber 312 towards the first chamber 311.

[0047] It should be noted here that the medium is a fluid, which can be a gas or a liquid.

[0048] In this embodiment, when the partition 322 drives the driving block 320 to move in the direction from the first chamber 311 towards the second chamber 312, the linkage portion 321 moves relative to the linkage groove 331 and the two alignment blocks 330 approach each other. When the partition 322 drives the driving block 320 to move in the direction from the second chamber 312 towards the first chamber 311, the linkage portion 321 moves relative to the linkage groove 331 and the two alignment blocks 330 move away from each other.

The outer side of the first sealing ring 400 contacts the inner side of the driving cavity, and the inner side of the first sealing ring 400 contacts the partition 322.

[0050] In this embodiment, the partition 322 contacts the inner side of the driving cavity through the first sealing ring 400, thereby preventing the first chamber 311 and the second chamber 312 from exchanging media through the gap between the partition 322 and the inner side of the driving cavity, and improving the sealing performance.

[0051] As Figures 1-6 shown, on the basis of the above embodiment, a first receiving groove 3221 is provided on the outer side of the partition 322. The first sealing ring 400 is located in the first receiving groove 3221, and the inner side of the first sealing ring 400 contacts the bottom of the first receiving groove 3221.

[0052] In this embodiment, the first sealing ring 400 is located in the first receiving groove 3221, and the inner side of the first sealing ring 400 contacts the bottom of the first receiving groove 3221. Therefore, the position of the first sealing ring 400 can be restricted to prevent the first sealing ring 400 from falling out of the partition 322.

[0053] As Figures 1-6As shown, on the basis of the above-described embodiment, the straightening block 330 is provided with a contact block 332.
