Since there are four sets of pistons inside the automotive clamp, the existing testing method tests the starting pressure of each piston individually, which suffers from low testing efficiency. Therefore, it is necessary to develop a new testing device that can complete the testing of the starting pressure of all four sets of pistons simultaneously, thereby solving the above-mentioned problems of the existing automotive clamp piston starting pressure testing method.

[0021] The automotive clamp piston start pressure detection device includes a mounting bracket 4, a conveyor line 1, a sliding clamp 2, a lifting and fixing assembly 3, a sliding frame 7, a servo motor 5, a drive screw 6, a swing plate 9, a pressure sensor 13, and a return cylinder 12 (see the instruction manual appendix). Figure 1 , 2 and 3).

[0022] Multiple sliding clamps 2 are movably mounted on conveyor line 1. Conveyor line 1 is existing equipment, and it can drive the multiple sliding clamps 2 to move synchronously during operation. Workpieces 21 (automotive clamps) are mounted on the sliding clamps 2.

[0023] Conveyor line 1 is equipped with lifting and fixing assembly 3 (see instruction manual appendix). Figure 1 The lifting and fixing assembly 3 includes a limiting claw 14 and a lifting cylinder 15 (see the instruction manual appendix). Figure 1 Multiple limit claws 14 are installed above the conveyor line 1; a lifting plate 16 is installed below the limit claws 14 via a lifting cylinder 15.

[0024] When the conveyor line 1 drives the sliding clamp 2 to move to the position corresponding to the lifting and fixing component 3 during operation, the lifting cylinder 15 can lift the sliding clamp 2 with the cooperation of the lifting plate 16 so that it is separated from the conveyor line 1, and finally clamp and fix the sliding clamp 2 with the cooperation of the limiting claw 14.

[0025] A drive screw 6 is mounted on the top of the lifting and fixing assembly 3 via a mounting bracket 4 and a servo motor 5; a sliding bracket 7 is slidably mounted on the mounting bracket 4 via a guide rail; the sliding bracket 7 is connected to the drive screw 6 (see the appendix of the instruction manual). Figure 3 and 8 The servo motor 5 drives the lead screw 6 to rotate, which in turn drives the sliding frame 7 to move up and down along the guide rail.

[0026] Four sets of assembly plates 8 are symmetrically mounted on the lower end of the sliding frame 7; a swing plate 9 is hinged to the inner side of the assembly plate 8; a lower contact 10 is mounted on one side of the lower end of the swing plate 9; an upper contact 11 is mounted on one side of the upper end of the swing plate 9; a pressure sensor 13 is mounted on the assembly plate 8 on one side of the upper contact 11 via a return cylinder 12; the pressure sensor 13 is in contact with the upper contact 11.

[0027] A limiting column 19 is fixedly installed at the lower middle part of the sliding frame 7 (see the instruction manual appendix). Figure 7 The purpose of setting the limiting column 19 is to ensure that when the sliding frame 7 moves down and drives the assembly plate 8 to be inserted into the workpiece 21 (automobile clamp) during operation, when the limiting column 19 abuts against the bottom of the workpiece 21 (automobile clamp), it indicates that the sliding frame 7 has moved to the designated position and has a positioning function.

[0028] Two sets of clamping heads 18 are symmetrically mounted on the mounting bracket 4 via clamping cylinders 17 (see instruction manual appendix). Figure 2 During operation, the clamping cylinder 17 can clamp and fix the workpiece 21 (automobile clamp) onto the sliding clamp seat 2 through the clamping head 18.

[0029] A buffer cylinder 20 is mounted on the mounting plate 8 above the lower contact 10; the piston end of the buffer cylinder 20 is connected to the corresponding swing plate 9 (see the instruction manual appendix). Figure 7The purpose of setting up the buffer cylinder 20 is twofold: first, to provide a certain buffer during the swinging process of the swing plate 9 under force to avoid the problem of inaccurate measurement caused by the swing plate 9 rotating too fast; and second, to enable the buffer cylinder 20 to drive the swing plate 9 to reset after the swing plate 9 completes the detection.

[0030] When the piston start pressure detection device of the car clamp is working, when the conveyor line 1 drives the sliding clamp 2 and the workpiece 21 (car clamp) to move to the position corresponding to the lifting and fixing assembly 3, the lifting cylinder 15 can lift the sliding clamp 2 with the cooperation of the lifting plate 16 so that it is separated from the conveyor line 1, and finally clamp and fix the sliding clamp 2 with the cooperation of the limiting claw 14.

[0031] After the lifting and fixing assembly 3 fixes the sliding clamp 2, the clamping cylinder 17 clamps and fixes the workpiece 21 (automobile clamp) on the sliding clamp 2 through the clamping head 18.

[0032] After the above steps are completed, the servo motor 5 drives the sliding frame 7 to move down along the guide rail to the designated station via the drive screw 6. At this time, the assembly plate 8 and the swing plate 9 are inserted into the workpiece 21 (automobile clamp), and each set of pistons of the workpiece 21 (automobile clamp) abuts against the lower contact point 10 of the corresponding swing plate 9.

[0033] The piston of the car clamp is then activated, causing it to press the swing plate 9 through the lower contact 10. Under this pressure, the swing plate 9 swings and presses the pressure sensor 13 through the upper contact 11. The pressure detected by the pressure sensor 13 is the starting pressure of the car clamp piston. In this way, the car clamp piston starting pressure detection device can complete the detection of four sets of piston starting pressures at once. After the above detection is completed, the swing plate 9 will reset in the return cylinder 12 and the buffer cylinder 20; subsequently, the sliding frame 7 resets, the clamping cylinder 17 resets, and the lifting and fixing assembly 3 resets, allowing the car clamp piston starting pressure detection device to enter the next working cycle.

[0034] This automotive clamp piston starting pressure testing device is compact and ingeniously designed, capable of testing the starting pressure of four sets of pistons at once. This solves the problem of low testing efficiency in existing automotive clamp piston starting pressure testing methods, making it particularly suitable for the needs of automotive clamp production.
