[0018] See also Figure 1-5 The present embodiment is a double-station grinding fixture for a caliper body, comprising a support frame 1, a cross brace 5 is provided on the top of the support frame 1, the cross brace 5 is arranged in the horizontal direction, and a station for placing the caliper body is provided at each end of the cross brace 5, and the two stations are arranged symmetrically, and each station is provided with a group of limiting bosses 4, and a groove matching the cylinder of the caliper body is provided in the limiting boss 4; a locking screw 7 is provided in the middle of the cross brace 5, and a pressing plate 8 is provided on the top of the locking screw 7, and the pressing plate 8 is arranged in the horizontal direction and extends to the two stations, and the two ends of the bottom surface of the pressing plate 8 are provided with grooves matching the shape of the top of the caliper body.
[0019] Furthermore, the bottom end of the locking screw 7 passes through the through hole downward and is equipped with a locking nut, and the top end of the locking screw 7 passes through the pressure plate 8 upward and is equipped with a pressure cap.
[0020] Furthermore, the limiting boss 4 is connected to the cross brace 5 by screws, so the limiting boss 4 matching the size of the workpiece 9 can be replaced.
[0021] Furthermore, the limiting boss 4 is composed of two parts, a boss A41 and a boss B42, and the bottom ends of the boss A41 and the boss B42 are connected to the cross brace plate 5 by bolts.
[0022] Furthermore, both ends of the cross brace plate 5 are located on both sides of each work station and are each provided with an adjusting bolt 2 , and a lug boss 3 is provided on the top of the adjusting bolt 2 , and the lug boss 3 is used to support the lug 92 of the caliper body.
[0023] Furthermore, the locking screw 7 is covered with a sleeve 6, the bottom end of the sleeve 6 is fixedly connected to the cross brace 5, a circle of bosses is provided in the middle of the locking screw 7, a compression spring 10 is installed between the bosses and the cross brace 5, and the compression spring 10 is covered on the outside of the locking screw 7; when the locking nut at the bottom end of the locking screw 7 is loosened, the locking screw 7 is automatically lifted upward under the elastic force of the compression spring 10, so that the pressure plate 8 releases the workpiece 9 and automatically lifts a certain distance. After the workpiece 9 is installed, the locking nut is tightened to move the locking screw 7 downward, thereby driving the pressure plate 8 to press and fix the workpiece 9 through the pressure cap.
[0024] During grinding, the two caliper bodies are gradually placed vertically and symmetrically on two workstations, and then the two workpieces 9 are clamped by locking bolts, and then the robot is started for automatic grinding. The grinding robot grinds along the contour of the casting, and the burr can basically be kept at 0-0.5mm, with a good consistency in appearance. In one grinding cycle, two caliper body castings can be ground at one time, thereby improving the grinding efficiency.
