Two limit rods 10 are movably penetrated on the horizontal section of the portal bracket 1. The lower ends of the two limit rods 10 are fixedly connected to the upper end of the support seat 2. The two limit rods 10 can provide limits for the lifting and lowering of the support seat 2 and the clamping mechanism, so that the support seat 2 cooperates with the clamping mechanism to steadily drive the parts to be processed to lift and lower. The two limit rods 10 are symmetrically distributed with the hydraulic cylinder 9 as the symmetry axis. The upper ends of the two limit rods 10 are fixedly connected to the limit blocks 11. The limit blocks 11 can prevent the limit rods 10 from being separated from the portal bracket 1, and the limit blocks 11 and the limit rods 10 are detachably threaded.

[0024] A bidirectional threaded rod 4 is horizontally rotated through the inner walls on the left and right sides of the cavity 3, and shift blocks 5 are threadedly sleeved on the threaded sections on both sides of the bidirectional threaded rod 4. A servo motor 6 is fixedly installed on the upper end of the right side of the support seat 2. The servo motor 6 is used to drive the first gear 12 to rotate, so that the first gear 12 drives the second gear 13 meshing with it to rotate, and the second gear 13 drives the coaxially connected bidirectional threaded rod 4 to rotate. The model of the servo motor 6 is: MSME-012S1. The servo motor 6 is transmission connected to the bidirectional threaded rod 4. The driving end of the servo motor 6 is provided with a first gear 12. The second gear 13 is coaxially fixedly connected to the end of the bidirectional threaded rod 4 located outside the cavity 3. The first gear 12 and the second gear 13 mesh with each other. The rotation of the bidirectional threaded rod 4 drives the two threaded sleeved shift blocks 5 to move along the strip opening The opening 7 moves horizontally relative to each other, so that the two shift blocks 5 can horizontally adjust the relative distance between the two second clamping blocks 23 and the two first clamping blocks 22. At the same time, the two shift blocks 5 can drive the two movable rods 18 to move relative to each other, so that the two movable rods 18 are in contact with the side edges of the parts to be processed, which is convenient for clamping and positioning the parts to be processed of different sizes. The side walls of the two shift blocks 5 are in sliding contact with the inner wall of the strip opening 7. A strip opening 7 is provided on the bottom of the cavity 3. The lower ends of the two shift blocks 5 are both arranged through the strip opening 7.

The clamping mechanism includes circular grooves 16 respectively arranged at the lower ends of the two fixed rods 8. The top surfaces of the two circular grooves 16 are fixedly connected with compression springs 17. The elastic performance of the compression spring 17 enables the movable rod 18 to drive the second clamping block 23 to move toward the first clamping block 22, so that the first clamping block 22 and the second clamping block 23 clamp and position the workpiece to be processed in the vertical direction. The two circular grooves 16 are each inserted with a movable rod 18. The upper ends of the two movable rods 18 are each fixedly connected with a circular limiting block 19. The lower ends of the circular grooves 16 are provided with an annular limiting groove 20. The circular limiting block 19 is movably inserted in the annular limiting groove 20 and is fixedly connected to the lower end of the compression spring 17. When the circular limiting block 19 moves in the annular limiting groove 20, The movable rod 18 moves in the circular groove 16 and stretches the compression spring 17, so that the compression spring 17 cooperates with the two first clamping blocks 22 and the second clamping blocks 23 to clamp and position the workpiece to be processed. The ends of the two movable rods 18 located outside the circular groove 16 are sleeved with a sealing ring 21, and the sealing ring 21 is fixedly connected to the lower end of the fixed rod 8. The annular side walls of the two fixed rods 8 near the lower ends are fixedly connected with the first clamping block 22, and the lower ends of the two movable rods 18 are fixedly connected with the second clamping block 23. The two first clamping blocks 22 and the second clamping blocks 23 are relatively distributed. The circular limit block 19 and the sealing ring 21 are both corrosion-resistant rubber products.

[0026] When the utility model is in use, the door-shaped bracket 1 is installed and fixed on the oxidation tank, the upper ends of the two fixing rods 8 are respectively connected to the two threaded holes 14, so that the external thread 15 is threadedly connected to the threaded hole 14, and the aluminum alloy part to be processed is placed between the adjacent first clamping block 22 and the second clamping block 23, and the servo motor 6 is started to drive the first gear 12 to rotate, so that the first gear 12 drives the second gear 13 meshing therewith to rotate, and the second gear 13 drives the coaxially connected bidirectional threaded rod 4 to rotate, so that the rotation of the bidirectional threaded rod 4 drives the two displacement blocks 5 threadedly sleeved to move horizontally relative to each other along the strip opening 7, so that the two displacement blocks 5 horizontally adjust the relative distance between the two second clamping blocks 23 and the relative distance between the two first clamping blocks 22, until the aluminum alloy part to be processed can be inserted between the two opposite ones. The second clamping block 23 is between the two movable rods 18, at this time, the two movable rods 18 are respectively in contact with the side edges of the part, and the part is pulled so that the two second clamping blocks 23 drive the movable rod 18 to stretch the compression spring 17 of the circular groove 16 under the limiting action of the circular limit block 19 and the annular limit groove 20, until the upper end of the part is in contact with the lower ends of the two first clamping blocks 22, so that the compression spring 17 cooperates with the two first clamping blocks 22 and the second clamping blocks 23 to clamp and position the part to be processed, which is convenient for clamping and positioning parts of different sizes. At this time, the hydraulic cylinder 9 is started to cooperate with the two limit rods 10 to drive the support seat 2 to descend vertically, so that the support seat 2 cooperates with the shift block 5 and the fixed rod 8 to drive the parts clamped and positioned between the two movable rods 18 to descend below the liquid level of the oxidation tank, replacing manual adjustment, reducing labor intensity, saving time and effort.
