[0056] Here’s how it works:

[0057] By sending the assembled high-voltage load switch onto the feeding platform 21, when the high-voltage load switch moves into the supporting plate 29, the motor 25 drives the lead screw 26 to rotate, and controls the lifting and moving of the cross plate 28.

[0058] After raising the height of the high-voltage load switch, use slide 1 3 to move the horizontal position of slide 2 31, so that the two ends of the rotating plate 33 are inserted into the open groove 20, and then use cylinder 1 334 to control the pressing plate 35 to move downward to clamp the base 1. In the process of clamping the base 1, the sliding block 36 is pushed to move toward another sliding block 36 through the bevel 39, and the upright frame 11 is clamped by the clamping rods 37 on the two sliding blocks 36, so as to clamp the base 1 and the upright frame 11 synchronously, and then the support plate 29 is moved downward to reset.

[0059] Then move the arc plate 691 on the fixed plate 62 to the transmission rod 13. When the arc plate 691 contacts the transmission rod 13, the protrusion 692 cooperates with the right-angle groove 14, so that when the arc plate 691 rotates, it can drive the transmission rod 13 to rotate, thereby realizing automatic testing of the operational smoothness of the high-voltage load switch. At the same time, the rectangular plate 66 moves toward the transmission rod 13 and is slidably connected to the transmission rod 13 through chamfer 2, so that the rectangular plate 66 slides smoothly onto the transmission rod 13. When the transmission rod 13 vibrates during the test process, the limit plate 652 connected to the rectangular plate 66 will produce an upward displacement, which is monitored by the displacement sensor 67.

[0060] And by controlling the rotation of the shaft 571, the cam 572 contacts the bevel groove 591 on the driven plate 59, so that the two cams 572 are alternately matched with the driven plate 59, and the two driven plates 59 are alternately close to the vertical plate 58, so that the detection rod 582 slides back and forth on the vertical plate 58, and the detection rod 582 intermittently moves toward the high-voltage load switch, and the high-voltage load switch is subjected to dynamic or static balance test to detect product quality.

[0061] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments, and the above embodiments and descriptions are only for explaining the principles of the present invention.
