Obviously, the described embodiments are only part of the embodiments of this patent, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this patent.

[0018] See also Figure 1 , Figure 2 , Figure 3 and Figure 4This patent provides a technical solution: a high-precision metal parts detection workbench, including a detection table 1, a nut is provided on the top of the detection table 1, a bracket 2 is fixedly installed on the top of the detection table 1, an internal thread ring 3 is connected to the side wall of the bracket 2 through a connecting rod, a screw 8 is screwed to the inner side wall of the internal thread ring 3, a motor 4 is connected to the side wall of the bracket 2 through a connecting rod, a rotating column 5 is fixedly installed at the bottom end of the rotating shaft of the motor 4, a square groove 6 is provided at the bottom end of the rotating column 5, a square rod 7 is slidably installed on the inner side wall of the square groove 6, the bottom end of the square rod 7 is fixedly installed on the top of the screw 8, and a detection piece 9 is provided at the bottom end of the screw 8;

[0019] The detection member 9 includes a horizontal column 10, a bulb 11 and a battery 12 are installed on the top of the side wall of the horizontal column 10, a slide groove 13 is provided at the right end of the horizontal column 10, a fixed contact 14 is installed on the left wall of the slide groove 13, a horizontal bar 15 is slidably installed on the inner side wall of the slide groove 13, a moving contact 16 is installed on the left end of the horizontal bar 15, a circular plate 17 is installed on the right end of the horizontal bar 15, a pressure wheel 18 is installed on the right side of the circular plate 17, a spring 19 is sleeved on the side wall of the horizontal bar 15, and the two ends of the spring 19 are respectively installed on the horizontal column 10 and the circular plate 17;

[0020] Figure 1 , 2 The spring 19 shown is in a compressed state. The compression effect of the spring 19 can press the pressure wheel 18 onto the inner wall thread of the nut to be detected, and at the same time, the moving contact 16 is pressed onto the fixed contact 14. At this time, the series circuit is connected and the light bulb 11 is lit.

[0021] The light bulb 11 and the fixed contact 14 are electrically connected through a wire, the moving contact 16 and the battery 12 are electrically connected through a wire, and the light bulb 11 and the battery 12 are electrically connected through a wire.

[0022] Specifically, the circular plate 17 includes a left circular plate 20 and a right circular plate 22. The right side surface of the left circular plate 20 is provided with a T-shaped groove 21, and the left side surface of the right circular plate 22 is integrally formed with a T-shaped rod 23. The shape and size of the T-shaped rod 23 match the internal shape and size of the T-shaped groove 21, and the T-shaped rod 23 is rotatably installed in the T-shaped groove 21.

[0023] The T-shaped rod 23 can rotate in the T-shaped slot 21 .

[0024] Since the inner wall thread of the nut is inclined, the T-shaped rod 23 can be rotated in the T-shaped slot 21, thereby changing the orientation of the pressure wheel 18 to correspond to the direction of the inner wall thread of the nut.

[0025] Specifically, the left circular plate 20 includes a plate body 24 and a circular ring 25 , and the left side surface of the circular ring 25 is fixedly mounted on the right side surface of the plate body 24 .

[0026] like Figure 4As shown, by dividing the left circular plate 20 into the plate body 24 and the circular ring 25 , it is convenient to open the T-slot 21 in the early stage and to install the T-bar 23 in the T-slot 21 .

[0027] Specifically, a wire hole 26 is provided on the top wall of the inner side wall of the slide slot 13 .

[0028] The wire holes 26 are used to accommodate wires of the series circuit.

[0029] Specifically, a positioning groove 27 is provided on the top of the detection platform 1 .

[0030] The positioning groove 27 is provided to limit the position of the nut to be detected.

[0031] Working principle: The rotation of the rotating column 5 is controlled by the motor, and the rotating column 5 drives the square rod 7 and the screw 8 to rotate. The screw 8 rotates in the internal thread ring 3 and moves downward. The pressure wheel 18 moves in the inner wall thread of the precision nut. When the thread is recessed, the pressure wheel 18 will also move toward the recess, and the moving contact 16 will be separated from the fixed contact 14, and then the light bulb 11 will go out. The above detection method can make the detection result more intuitive and effective, and the detection efficiency is guaranteed.

In terms of the technology of this design principle, the settings of the device's power mechanism, power supply system and control system are not fully described. However, on the premise that technical personnel in this field understand the principles of the above patent, they can clearly know the details of its power mechanism, power supply system and control system.
