Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0017] like Figures 1 to 3As shown, an embodiment of the present application provides a square tube processing fixture, including a base 1, a fixed component is provided on the base 1, and two symmetrical inner clamping blocks 2 and two symmetrical outer clamping blocks 3 are slidingly connected to the fixed component along the X-axis direction.

[0018] During operation, the core part of the square tube is aligned with the inner clamping block 2, so that the two inner clamping blocks 2 are both located in the core of the square tube. At this time, the two outer clamping blocks 3 are both located on the outside of the square tube. Then the first driving component drives the two inner clamping blocks 2 away from each other, so that the two inner clamping blocks 2 are respectively against the two inner walls of the square tube. Then the second driving component drives the two outer clamping blocks 3 closer together, so that the outer clamping blocks 3 are against the outer wall of the square tube. At this time, each inner clamping block 2 corresponds to one of the outer clamping blocks 3 to clamp one side wall of the square tube.

[0019] The above structure is set up by arranging a fixing component on the base 1, and slidingly connecting two mutually symmetrical inner clamping blocks 2 and two mutually symmetrical outer clamping blocks 3 on the fixing component, and arranging a first driving component for driving the two inner clamping blocks 2 to move closer or farther away and a second driving component for driving the two outer clamping blocks 3 to move closer or farther away, so that the two inner clamping blocks 2 can respectively cooperate with the two outer clamping blocks 3 to clamp the side walls of the square tube, so that the forces exerted on the inner and outer walls of the square tube can be offset, making the square tube not easy to deform, and the inner clamping blocks 2 and the outer clamping blocks 3 can move within a certain range, so that square tubes of different specifications can also be applied.

The outer clamping block 3 is provided with a first outer slider 31 that is slidably connected to the first slide groove 111 and a second outer slider 32 that is slidably connected to the second slide groove.

[0021] The above structure is set up by setting the fixing component as the first fixing block 11 and the second fixing block 12, and setting the first sliding groove 111 and the second sliding groove on the first fixing block 11 and the second fixing block 12 respectively, so as to facilitate the sliding connection between the inner clamping block 2 and the outer clamping block 3 and the fixing component.

[0022] In this embodiment, the first driving assembly includes a first screw rod 4, one end of the first screw rod 4 is rotatably connected to one end of the first fixed block 11, and the other end of the first fixed block 11 is provided with a first communicating hole, and the end of the first screw rod 4 close to the first communicating hole passes through the first communicating hole along the X-axis direction and is fixedly connected to the first knob 41, the first screw 4 includes a first positive screw rod and a first reverse screw rod connected to one side of the first positive screw rod, the spiral directions of the first positive screw rod and the first reverse screw rod are opposite, and the two first inner sliding blocks 21 are respectively provided with a first positive threaded hole adapted to the first positive screw rod and a first reverse threaded hole adapted to the first reverse screw rod, the first positive screw rod is threadedly connected to the first positive threaded hole, and the first reverse screw rod is threadedly connected to the first reverse threaded hole, and the two first outer sliding blocks 31 are both provided with a first clearance hole for the first screw 4 to pass through.

[0023] During operation, the first knob 41 is rotated and the first screw 4 rotates. The first screw 4 is set to be composed of a first positive spiral rod and a first reverse spiral rod with different spiral directions, and the two first inner sliders 21 are respectively threadedly connected to the first positive spiral rod and the first reverse spiral rod, so that when the first screw 4 rotates, the two first inner sliders 21 are driven by the thread force to move in opposite directions, so that the two inner clamping blocks 2 can be closer or farther away, and first clearance holes are set on the two first outer sliders 31, so that the outer clamping block 3 is not affected when the inner clamping block 2 moves.

[0024] In this embodiment, the second driving assembly includes a second screw, one end of the second screw is rotatably connected to one end of the second fixed block 12, and the other end of the second fixed block 12 is provided with a second communicating hole, and the end of the second screw close to the second communicating hole passes through the second communicating hole along the X-axis direction and is fixedly connected to the second knob, the second screw includes a second positive screw rod and a second reverse screw rod connected to one side of the second positive screw rod, the second positive screw rod and the second screw rod have opposite spiral directions, and the two second outer sliding blocks 32 are respectively provided with a second positive threaded hole adapted for the second positive screw rod and a second reverse threaded hole adapted for the second reverse screw rod, the second positive screw rod is threadedly connected to the second positive threaded hole, and the second reverse screw rod is threadedly connected to the second reverse threaded hole, and the two second inner sliding blocks 22 are both provided with a second clearance hole for the second screw to pass through.

The two centering assemblies are symmetrical to each other, and the distances between the two centering assemblies and the inner clamping block 2 are equal.

[0027] The above structure is set up with centering components on both sides of the inner clamping block 2, so that the distance from the two side walls of the square tube that are not clamped to the inner clamping block 2 is the same, preventing the placement of multiple square tubes from being inconsistent when processing.

[0028] In this embodiment, the centering component located on the first inner slider 21 includes a connecting block 5 fixedly connected to the first inner slider 21, a third sliding groove 211 is provided on the first inner slider 21 along the Y-axis direction, a third slider is slidably connected in the third sliding groove 211, a pressure block 52 is fixedly connected to the third slider, and the pressure block 52 is connected to the connecting block 5 by a spring 51.

[0029] Specifically, the centering assembly on the second inner slider 22 is symmetrical to the centering assembly on the first inner slider 21 , that is, both centering assemblies include a connecting block 5 , a spring 51 and a pressing block 52 .

[0030] During operation, the two pressure blocks 52 are respectively pressed against the two outer walls of the square tube under the action of the spring 51. It should be noted that the elastic force of the two springs 51 is the same, so that the two pressure plates exert the same pressure on the square tube, so that the square tube is located between the two connecting plates.
