Description

Technical Field

[0001] The utility model belongs to the technical field of centering devices, and particularly relates to a centering device for a welding die. Background Art

[0002] When welding dies by splicing, it is necessary to center the dies to be welded to prevent position deviation during welding. When centering existing circular dies, the clamping point positions are fixed. If the lengths of the dies are inconsistent, there is no way to adjust adaptively, and additional fixtures are required to fix the dies. The operation is not only cumbersome, and the fixation with additional fixtures cannot guarantee the centering accuracy. Therefore, we propose a centering device for a welding die to solve the above problems. Content of the Utility Model

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts belong to the scope of protection of the present invention.

[0025] Embodiment: As Figure 1 shown, a centering device for a welded blank die includes a workbench 10. A first workpiece 20 is also clamped inside the workbench 10. A through hole is correspondingly opened at the middle position of the workbench 10 corresponding to the first workpiece 20. The first workpiece 20 vertically falls on the ground or other stoppers through this through hole (for example, a clamping structure can also be provided on the ground to fix the bottom end of the first workpiece 20). Among them, the upper end of the first workpiece 20 also contacts a second workpiece 21; the periphery of the contact surface between the first workpiece 20 and the second workpiece 21 is the welding point; [[ID=eleven]]

[0026] As Figure 2 shown, a cylinder body 41 is also fixedly installed at the middle position of the upper end surface of the workbench 10. There are two groups of cylinder bodies 41. A clamping block 40 is fixedly connected to the opposite ends of the output shafts of the two groups of cylinder bodies 41. The clamping block 40 can clamp and fix the upper part of the first workpiece 20;

[0027] Among them, as Figure 2-4 shown, a rodless cylinder is also provided on the upper end surface of the workbench 10. The rodless cylinder includes a stator 31 fixedly installed on the workbench 10 and a rotor 31a that moves linearly along the stator 31. The rotor 31a is fixedly connected to a moving seat 30 for driving the moving seat 30 to move linearly along the workbench 10. Among them, there are two groups of moving seats 30. The two groups of moving seats 30 can move relatively away from or close to each other. Adjusting jigs 32 are also provided on the opposite side walls of the two moving seats 30 for fixing the second workpiece 21; by adjusting the distance between the two moving seats 30, the distance between the adjusting jig 32 and the second workpiece 21 can be adjusted, which is convenient for the adjusting jig 32 to fix the second workpiece 21;

[0028] Among them, as Figure 3-4 shown, the adjusting jig 32 includes a connecting seat 321 fixedly arranged on the side of the moving seat 30. An adjusting rod 322 is also movably sleeved inside the connecting seat 321. The adjusting rod 322 is connected to the connecting seat 321 through a rotating shaft. And a clamping member 323 is also movably arranged at the end of the adjusting rod 322 away from the moving seat 30. Similarly, the clamping member 323 is also movably connected to the adjusting rod 322 through a rotating shaft. As Figure 3As shown, a clamping opening 325 is provided on the contact surface between the clamping member 323 and the second workpiece 21; and the clamping opening 325 is V-shaped;

[0029] During use, for a mold with a consistent thickness, the position of the clamping member 323 can be adjusted by rotating the adjusting rod 322, so that the clamping member 323 leans on a point at the upper part and a point at the lower part of the second workpiece 21. Since at least two groups of adjusting rods 322 are provided, at least two points at the upper and lower parts of the second workpiece 21 are clamped and fixed. A bolt 50 is also provided between the two groups of clamping members 323. Fixing holes 324 are correspondingly provided on the inner sides of both ends of the clamping member 323 for the bolt 50 to pass through. After the bolt 50 passes through, both ends of the bolt 50 can be fixed by nuts, so as to fix two points at the upper and lower parts of the second workpiece 21;

[0030] If the thickness of the second workpiece 21 is inconsistent, because the adjusting rod 322 and the clamping member 323 are movably connected, the upper and lower parts of the second workpiece 21 can be fixed by adjusting a certain group of clamping members 323 alone;

[0031] Such as Figure 2 As shown, a V-shaped clamping opening is also provided on the contact surface between the clamping block 40 and the first workpiece 20, which is convenient for fixing the first workpiece 20;

[0032] Such as Figure 1 As shown, a hydraulic leg rod 11 is fixedly installed on the lower end surface of the workbench 10, which is used to drive the workbench 10 to move up and down, adjust the height of the workbench 10 according to the height of the first workpiece 20, and at the same time, the position of the adjusting fixture 32 can also be adjusted.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
