[0031] In the initial state, there is a gap between the locking block 47 and the pressure sensors 46 on both sides. A second transverse guide rail 441 is set on the vertical movable plate 44. The locking block 47 is movably set on the second transverse guide rail 441. A limiting screw 49 for limiting the upper position of the vertical movable plate 44 is set at the top of the transverse plate 43.

[0032] like Figure 9-11 As shown, the height detection position 50 includes a fourth vertical plate 51 arranged on the second movable plate 114, a lifting motor 52 is arranged on one side of the fourth vertical plate 51, and the output end of the lifting motor 52 is connected to a vertical screw through a synchronous belt and a synchronous wheel, and a lifting plate 53 is arranged on the screw, and the lifting plate 53 is located on the other side of the vertical plate, and a lifting guide rail 511 is arranged on the fourth vertical plate 51, and the 53 lifting plate is arranged on the lifting guide rail 511, and a second U-shaped plate 54 is arranged on the lifting plate 53, and two groups of detection rods 55 are arranged in parallel on the second U-shaped plate 54, and the detection rods 55 are connected to the second U-shaped plate through linear bearings 56 so that they can move up and down along the second U-shaped plate, and both ends of the detection rods 55 can pass through the second U-shaped plate.

[0033] A limiting boss 551 is provided on the portion of the detection rod 55 within the second U-shaped plate, and a spring 57 is sleeved on the detection rod below the limiting boss 551. The bottom end of the spring 57 abuts against the U-shaped plate. When the detection rod 55 rises and contacts the detection part, buffering can be achieved through the spring.

[0034] A moving cylinder 58 is also provided on the second moving plate 114 . A laser displacement sensor 59 is provided at the output end of the moving cylinder 58 via a mounting plate. The laser displacement sensor 59 can be moved to the bottom of the detection rod 55 .

The torque detection device drives the detection head to move to the torque detection point A, and the rotary motor drives the detection head to rotate, thereby driving the torque detection point A to rotate along the range of the arc groove, and the torque value is recorded by the torque sensor. At this time, the height detection point C moves downward a certain distance under the rotation of A, and then the lateral movement assembly drives the height detection device to move to the bottom of the part. In the initial state, the two detection rods are at the same horizontal height. After the top end of the detection rod contacts point C and point D, its bottom end extends downward, and then the laser displacement sensor moves to the detection point C. At the bottom end of the measuring rod, the height data of the bottom of the two detection rods are recorded by the laser displacement sensor, and then the pressure test is performed. First, the transverse movement motor rotates forward, and the locking block drives point B to rotate to the left to lock the part. The pressure sensor detects the locking pressure and records the locking pressure. At this time, the torque detection device drives the detection head to reset, and then the transverse movement motor reverses, and the locking block drives point B to reset to the right to unlock the part. The pressure sensor detects the unlocking pressure and records the locking pressure. At this time, point A and point C are reset at the same time. Finally, the laser displacement sensor detects the position of the detection rod after unlocking and records it, and then determines whether the height difference between point C and point D is within the qualified range.
