DETAILED DESCRIPTION OF THE EMBODIMENTS

[0020] The following will further elaborate on the present application in conjunction with the attached Figure 2-3 for a more detailed description of the present application.

[0021] An embodiment of the present application discloses a clamping fixture for box body processing. Refer to Figure 2-3, including a bottom plate 1, a radial clamping mechanism, an axial inner support mechanism and a support rod 2 arranged on the bottom plate 1. The radial clamping mechanism includes a clamping unit 31 and two radial limit blocks 32. The two radial limit blocks 32 are symmetrically fixed on the bottom plate 1, and the radial limit blocks 32 are arranged on different sides from the clamping unit 31;

[0022] The axial inner support mechanism includes a corresponding inner support unit 41 and an axial limit block 42, and the axial limit block 42 is fixed on the bottom plate 1;

[0023] Both the radial limit block 32 and the axial limit block 42 include a main body 421. A limit groove is opened on the side of the top end of the main body 421, and a limit pad 422 is detachably fixed in the limit groove. A height equalizing pad 5 is also fixed on the top end of the main body 421, and a height equalizing pad 5 is also fixed on the top of the support rod 2. The support rod 2, the axial limit block 42 and the two radial limit blocks 32 can support the box body;

[0024] In order to facilitate the hoisting and transfer of the fixture, lifting rings 6 are installed at the four corners of the bottom plate 1.

[0025] Refer to Figure 2-3 , on the side of the bottom plate 1 far from the radial limit block 32, two first guide blocks 11 are fixed. A guide notch is opened on the side of the first guide block 11 close to the radial limit block 32. On the side of the bottom plate 1 far from the axial limit block 42, a second guide block 12 is fixed. A guide notch is opened on the side of the second guide block 12 far from the axial limit block 42.

[0026] By providing the first guide block 11 and the second guide block 12, it can assist the staff to place the box body on the fixture and realize the placement of the approximate position of the box body, which is convenient for subsequent clamping, thereby improving production efficiency.

[0027] Refer to Figure 2 , both the clamping unit 31 and the inner support unit 41 include a bracket, a cylinder and a rotating arm 7. The bracket is fixed on the bottom plate 1, the cylinder is installed on the bracket, a connecting rod 8 is hinged on the rotating arm 7, one end of the connecting rod 8 is hinged on the bracket, and the bottom end of the rotating arm 7 is hinged to the piston rod of the cylinder. A clamping pad is detachably fixed on the side of the rotating arm 7 in the clamping unit 31 close to the radial limit block 32, and a clamping pad is detachably fixed on the side of the rotating arm 7 in the inner support unit 41 far from the axial limit block 42;

[0029] The implementation principle of a clamping fixture for box body processing in the embodiment of the present application is as follows:

[0030] The staff roughly place the box on the jig along the first guide block 11 and the second guide block 12 in advance, and it stays stably on the jig under its own gravity. After that, the cylinder in the clamping unit 31 extends to push the rotating arm 7 to rotate. The top of the rotating arm 7 abuts against the reinforcing rib at the bottom of the box and cooperates with the two radial limit blocks 32 to clamp the box. The cylinder in the inner support unit 41 shortens to drive the rotating arm 7 to rotate, and the top of the rotating arm 7 flips outwards, cooperating with the axial limit block 42 to support the box tightly from the inner walls of the reinforcing ribs on both sides of the bottom of the box. The clamping effect is good, leaving a large operating space for the surface processing of the box.

[0031] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape, and principle of this application shall be covered within the protection scope of this application.
