[0002] A chain link is a ring-shaped connecting structure used to connect two adjacent chains. The structure is generally formed by locking and fastening two half-waist-shaped structures. Therefore, the two half-waist-shaped structures need to be surface processed at the connection position. The surface processing of the traditional connection position is clamped by multiple clamps, such as the front, back, left, and right sides. This form is inconvenient for surface processing. Based on this, the utility model proposes a chain link clamping tool. Utility Model Content

[0006] The bottom mold comprises a mold, a drilling hole is arranged at the center position of the front and rear end surfaces of the mold, a positioning bottom block is arranged at the bottom end of the mold; and a positioning hole matching with the positioning bottom block is opened on the tooling table.

[0007] Furthermore, the tooling table includes a workbench, on which a slide rail is provided for the sliding of the clamping block, and a slider is provided at the bottom of the clamping block; a plurality of threaded holes are provided on the workbench, and connecting bolts are provided in the threaded holes, and the connecting bolts fix the tooling table and the positioning column together.

[0008] Furthermore, the positioning column comprises a body, an inner staggered platform is provided downwardly at the center of the body, and an inner threaded hole matching with the threaded hole is provided at the center of the inner staggered platform.

[0009] Furthermore, the inner offset platform is connected to the connecting bolts.

[0010] Furthermore, the interior of the mold is a hollow structure.

[0011] Compared with the prior art, the beneficial technical effects of the utility model are:

[0012] The utility model realizes the clamping effect of the butt joint chain ring by mutually clamping the positioning column and the clamping block. Meanwhile, the bottom mold not only plays a certain positioning function in the butt joint chain ring during the precise processing, but also avoids the front and rear movement of the butt joint chain ring during the processing, thereby achieving the purpose of improving the processing accuracy and quality.

[0021] like Figure 1-3 As shown, a clamping tool for connecting a chain ring includes a tooling table 1, on which positioning columns 2 are symmetrically installed, and a bottom mold 4 is installed in the middle position of the positioning columns 2. The arc end of the connecting chain ring 7 is located at the outer periphery of the positioning columns 2, and the outer side wall of the arc end of the connecting chain ring 7 is in contact with a clamping block 5, and the clamping block 5 and the positioning column 2 together realize the clamping of the connecting chain ring 7. The other end of the clamping block 5 is connected to a cylinder 6, and is driven to move left and right by the cylinder 6. The front and rear end surfaces of the bottom mold 4 are against the inner side wall of the straight end of the connecting chain ring 7 to prevent the connecting chain ring 7 from moving in the front and rear directions.

[0022] The bottom mold 4 includes a mold 401, a drill hole 403 is installed at the center of the front and rear end surfaces of the mold 401, and a positioning bottom block 402 is installed at the bottom of the mold 401; the tooling table 1 is provided with a positioning hole 104 that matches the positioning bottom block 402. When drilling the side of the docking chain link 7, the drill bit can enter the drill hole 403 to ensure that the drilling operation is completed smoothly.

[0023] The tooling table 1 comprises a workbench 101, on which a slide rail 102 for the clamping block 5 to slide is provided, and a slider is installed at the bottom of the clamping block 5. The workbench 101 is provided with a plurality of threaded holes 103, in which connecting bolts 3 are installed, and the connecting bolts 3 fix the tooling table 1 and the positioning column 2 together.

[0024] The positioning column 2 includes a body 201 , and an inner staggered platform 202 is provided downwardly at the center of the body 201 . An inner threaded hole 203 matching with the threaded hole 103 is provided at the center of the inner staggered platform 202 .

[0025] The inner offset platform 202 is connected by the connecting bolts 3 .

[0026] The interior of the mold 401 is a hollow structure for waste chips to fall into, thereby preventing the waste chips from damaging the cutter head of the drilling tool.
