[0030] Example 3: Structure and function of positioning plate 21

[0031] A receiving groove 19 is provided at the top of the workbench 1. The workbench 1 is located in the receiving groove 19 and a bidirectional screw 20 is rotatably installed. Positioning plates 21 are threadedly installed on both sides of the bidirectional screw 20. A No. 2 motor 22 is fixedly installed on one side of the workbench 1. The output end of the No. 2 motor 22 is fixedly connected to the bidirectional screw 20. By starting the No. 2 motor 22, the bidirectional screw 20 is driven to rotate, and the positioning plate 21 is moved to limit and clamp the sheet metal parts, thereby enhancing the detection stability.

[0032] Example 4: Design and function of rubber pad

[0033] Rubber pads are fixedly mounted on opposite sides of the two positioning plates 21 . By providing the rubber pads, damage to the surface of the sheet metal component can be avoided as much as possible.

[0034] The bottom of the workbench 1 is fixed with a fixed seat 23 on both sides, and the bottom of the fixed seat 23 is rotatably mounted with a roller 24. The setting of the roller 24 facilitates the movement of the device.

[0035] Example 5: Working principle of the detection fixture

[0036] The user starts the second motor 22 to drive the bidirectional screw 20 to rotate, so that the positioning plate 21 moves, and the sheet metal part is clamped in a limited position to enhance the detection stability.

[0037] Before installing the positioning block 11, the movable plate 16 is moved to extend the spring 15, and then the insert block 12 is inserted into the slot 13, and then the movable plate 16 is loosened to contract the spring 15, and the limiting rod 17 is inserted into the limiting hole 14 to lock and limit the insert block 12. When the positioning block 11 needs to be replaced, the movable plate 16 is pulled by the pull ring 18 to move the spring 15, and the limiting rod 17 falls off the limiting groove, making it easy to replace the positioning block 11 and reducing the labor intensity of the staff.

[0038] Technical Effects

[0039] The detailed description of the above embodiments demonstrates the significant advantages of the present invention in hole positioning detection applications. First, the arrangement of the first motor 8, rotating disk 9, mounting block 10, positioning block 11, insert block 12, and slot 13 facilitates the installation of multiple positioning blocks 11, making it suitable for detecting holes of varying sizes, extending the detection range, and enhancing practicality.

[0040] Secondly, the arrangement of the limiting hole 14, the spring 15, the movable plate 16, the limiting rod 17 and the pull ring 18 facilitates the disassembly and replacement of the positioning block 11, thereby improving the disassembly and assembly efficiency of the positioning block 11 and enhancing the convenience of use.
