[0017] Referring to Figures 1-5 , this embodiment provides a horizontal grinding tooling for automotive caliper body castings, including a support frame 1. A horizontal support plate 6 is installed on the top of the support frame 1. In the middle of the front end of the top surface of the support plate 6, a positioning block A 3 is installed. The top of the positioning block A 3 is provided with a positioning surface matching the outer wall contour of the caliper cylinder. On both sides of the rear end of the top surface of the support plate 6, a positioning block B 4 is installed respectively. The top of the positioning block B 4 is provided with a positioning surface matching the back contour of the caliper head; On both sides of the support plate 6, a support rod 2 is installed respectively. The support rod 2 is used to support the lugs on both sides of the caliper cylinder; Through the positioning block A 3 and the positioning block B 4, the central axis of the cylinder body is along the horizontal direction when the caliper is placed, that is, the workpiece 5 is positioned and placed in a lying position, enabling the grinding robot to grind the upper surface of the workpiece 5.

[0018] Furthermore, a positioning block C 8 is also installed between the two positioning blocks B 4. The top of the positioning block C 8 is provided with an auxiliary support surface matching the back contour shape of the caliper.

[0019] Further, the support rod 2 includes a bolt and a nut. An installation hole is provided on the support plate 6 corresponding to the support rod 2. The bolt passes through the installation hole and nuts are installed on both sides. The support height of the bolt is adjusted by the nuts; by turning the nuts to adjust the support height of the bolt, the lugs on both sides of the workpiece 5 are supported, which can play a role in leveling the workpiece 5.

[0020] Further, the bottom surfaces of the positioning block A 3 and the positioning block B 4 are both connected to the support plate 6 by screws.

[0021] Further, a kidney-shaped hole 7 is provided on the support plate 6 corresponding to the positioning block A 3. The connecting screw of the positioning block A 3 is installed in the kidney-shaped hole 7. By adjusting the fixed position of the screw in the kidney-shaped hole 7, the positioning block A 3 can move a certain distance along the long axis of the kidney-shaped hole 7, so as to realize fine adjustment of the position of the positioning block A 3.

[0022] Further, the long axis of the kidney-shaped hole 7 is arranged parallel to the axis of the caliper cylinder block.

[0023] When the present utility model is working, the support frame 1 is fixedly installed at the working position of the grinding robot, and the workpiece 5 is placed in the tooling, so that the back surface of the workpiece 5 naturally fits against the positioning surfaces of the positioning block A 3 and the positioning block B 4, realizing the lying placement of the workpiece 5. Then, the grinding robot grinds the upper surface of the workpiece 5 according to the set program.

[0024] When the size of an individual workpiece 5 is out of tolerance and cannot be placed in the tooling, by finely adjusting the position of the positioning block A 3, the distance between the positioning block A 3 and the positioning block B 4 is increased, so as to increase the accommodating space of the tooling, enabling the out-of-tolerance workpiece 5 to be smoothly placed in the tooling.
