[0003] The caliper generally adopts a casting production process, with various structural forms. There are some burrs on the surface of the caliper casting that need to be ground. Due to the high labor intensity of the grinding work, the harsh on-site environment, and the difficulty in recruiting workers, it is impossible to ensure timely supply to the market. Therefore, it is necessary to use an automated robot to replace manual grinding; when the robot grinds, the workpiece needs to be positioned and placed on a special tooling. Currently, the form and structure of the tooling are relatively complex, and there are certain errors in the casting size. Some workpieces with larger errors cannot be smoothly placed into the tooling. Summary of the Invention

A positioning sink A is provided on one side of each of the two support columns A facing the support column B, and a positioning sink B is provided on one side of each of the two support columns B facing the support column A. The positioning sink A matches the bottom contour shape of the back of the cylinder block of the caliper body, and the positioning sink B matches the bottom contour shape of the front of the cylinder block of the caliper body; the caliper body is placed vertically through the positioning sink A and the positioning sink B.

[0006] Further, an auxiliary support seat is also installed on the top of the support plate, and a positioning groove is provided on the top of the auxiliary support seat, and the positioning groove matches the contour of the bottom surface of the caliper body cylinder block.

[0007] Further, both the support column A and the support column B are connected to the support plate by bolts.

[0008] Further, kidney-shaped holes are provided on the support plate corresponding to the support column A and the support column B, and the position of the support column A or the support column B can be finely adjusted through the kidney-shaped holes.

[0009] Further, a connecting rod is installed at the upper outer sides of the two support columns A, and both ends of the connecting rod are connected to the two support columns A by bolts.

[0010] The utility model has the following advantages compared with the prior art: 1. Simple structure, low cost and easy to replace; 2. The position of the positioning support column can be finely adjusted to adapt to workpieces with large size errors and meet the grinding requirements. Description of the Drawings

[0019] Referring to Figures 1-7 , this embodiment provides a vertical grinding tooling for an automotive caliper body casting, including a support frame 1, a horizontal support plate 2 is installed on the top of the support frame 1, a support column A 3 is installed on each of the left and right sides of the front end of the top surface of the support plate 2, and two support columns B 4 are installed at the rear end of the top surface of the support plate 2. A positioning sink A 31 is provided on one side of each of the two support columns A 3 facing the support column B 4, and the positioning sink A 31 is provided with a horizontal support surface. A positioning sink B 41 is provided on one side of each of the two support columns B 4 facing the support column A 3, and the positioning sink B 41 is provided with an arc-shaped support surface. The positioning sink A 31 matches the bottom contour shape of the back of the cylinder block of the caliper body, and the positioning sink B 41 matches the bottom contour shape of the front of the cylinder block of the caliper body; the caliper body is placed vertically through the positioning sink A 31 and the positioning sink B 41, and the axis of the cylinder hole is kept in a vertical state.

[0020] Further, an auxiliary support base 7 is also installed on the top of the support plate 2. A positioning groove is provided on the top of the auxiliary support base 7, and the contour of the positioning groove matches the bottom surface of the caliper body cylinder.
