The detection rods 6 can be fixed after the height is adjusted, and a supporting plate 19 is arranged below the moving plate 2, and the supporting plate 19 is fixedly connected to the moving plate 2 through two connecting plates 12, and the supporting plate 19 is arranged through and slidably connected to a plurality of contact rods 9, and the lower ends of the contact rods 9 are fixed with buffer pads, and the upper ends of the contact rods 9 are fixedly connected with lower contact heads 8, and the lower contact heads 8 are respectively communicated and connected with the upper contact heads 7 above them, and after the lower contact heads 8 and the upper contact heads 7 are in contact, instructions are sent to an external processor, and the lower contact heads 8 and the upper contact heads 7 are powered by an external power supply. The contact between the two to send instructions to the processor is an existing mature technology and will not be repeated here. An indicator light 18 is fixedly provided on the upper wall of the detection frame 1, and the upper contact heads 7 and the lower contact heads 8 are both in communication connection with the indicator light 18. When all the upper contact heads 7 and the lower contact heads 8 are in contact and send signals to the processor, the indicator light 18 lights up.

[0022] A fixed plate 3 is arranged above the movable plate 2, and a plurality of second screws 4 are arranged through the fixed plate 3 and threadedly connected. The second screws 4 are coaxially fixedly connected to the detection rods 6 therebelow, and a limiting plate 5 is fixedly connected above the second screws 4. The rotation of the second screws 4 can adjust the height of the detection rods 6.

A slide rod 16 is fixedly provided in the left slide groove 13, and the slide rod 16 is provided through the slider 14 and slidably connected thereto, and a first screw rod 15 is rotatably provided in the right slide groove 13. The first screw rod 15 is provided through the slider 14 and is threadedly connected thereto, and the upper end of the first screw rod 15 is provided through the upper wall of the detection frame 1 and is rotatably connected thereto, and a motor 17 for driving the first screw rod 15 to rotate is fixedly provided on the upper wall of the detection frame 1.

[0024] Two clamping plates 10 are arranged inside the detection frame 1 . The left clamping plate 10 is fixedly connected to the left inner wall of the detection frame 1 , and the right clamping plate 10 is connected to the right inner wall of the detection frame 1 via a telescopic rod 11 .

[0025] In the actual detection process, the left side of the workpiece is first pressed against the left clamping plate 10, and the telescopic rod 11 is started to drive the right clamping plate 10 to move so as to clamp the workpiece. Figure 2As shown, the corresponding second screw rod 4 is rotated according to the height difference of the upper wall of the workpiece, so that the height of the detection rod 6 changes, and then the position of each detection rod 6 is determined according to the height difference of the workpiece surface and the scale on the detection rod 6; at this time, the motor 17 is started, and the moving plate 2 and the supporting plate 19 move, as shown in FIG.
