Description

[0002] Laser scanning inspection devices are equipment that use laser scanning technology to perform high-precision inspection of the shape, size, defects, etc. of objects. They are widely used in quality inspection in industrial manufacturing, 3D modeling in reverse engineering, structural monitoring in the construction field, and non-destructive testing in cultural relic protection.

[0003] Existing laser scanning detection devices for gear meshing clearance mainly suffer from poor versatility, insufficient adaptability to gears of different specifications, and the tendency to have scanning blind spots.

[0004] The meshing clearance in the blind zone cannot be effectively captured, which may lead to the omission of key dimensional data. As a result, the test results cannot fully reflect the actual meshing state of the gears, leading to deviations in the judgment of whether the clearance is qualified. The device is difficult to meet diverse test requirements. When dealing with gears of different specifications, the equipment needs to be frequently replaced or adjusted, or even cannot complete the test, which reduces the test efficiency and increases additional equipment investment or labor costs. Therefore, a laser scanning test device for gear meshing clearance is proposed to solve the above problems. Utility Model Content

A support rod 25 is fixedly connected to the bottom of the fixing ring 24. The support rod 25 is vertically connected to the bottom of the fixing ring 24 and mainly plays the role of connection and transmission. A fixing plate 26 is fixedly connected to the adjacent side of the two ends of the second drive shaft 23. The fixing plate 26 is connected to the adjacent end of the two drives shaft 23 and plays the role of limiting and fixing the second drive shaft 23.

The fixing disk 27 is installed between the two fixing plates 26 as an intermediate connecting component, connecting the two fixing plates 26 into a whole and enhancing the stability of the structure.

[0037] A connecting shaft 28 is fixedly connected to the outside of the fixed disk 27. The connecting shaft 28 extends from the outside of the fixed disk 27 to both sides. Its main function is to connect the fixed disk 27 with other transmission components and provide a support shaft for the installation of gear 20.

The bottom of the shift shaft 31 is fixedly connected to the abutment plate 33. The abutment plate 33 is installed at the bottom of the shift shaft 31. When the shift shaft 31 slides downward, the abutment plate 33 can contact the detection object or other components below, and can play a role in positioning and fixing the detection object.

[0038] A second motor 34 is fixedly connected to the bottom of the fixed disk 27. The second motor 34 is installed at the bottom of the fixed disk 27 and serves as an independent power source to provide rotational power to the third drive shaft 35.

[0039] Working principle: After the detection begins, the scanner 20 detects the size of the target object. When it finds that the current height cannot accurately detect the meshing clearance of the target gear, it sends the information to the dual-axis motor 6. The dual-axis motor 6 will drive the drive shaft 5 according to the received information. The drive shaft 5 will drive the gear 17 to rotate. The gear 17 will drive the gear shaft 15 that meshes with it to move. The gear shaft 15 will drive the shift block 18 to move. The shift block 18 will drive the roller 14 to move. The roller 14 will drive the support column 8 to move up and down, thereby driving the scanner 20 to move up and down.

[0040] When the target is placed in front of the fixed plate 26, the second motor 34 will drive the third drive shaft 35 to rotate. The third drive shaft 35 will drive the third gear 37 fixedly connected to it to rotate. The third gear 37 will drive the second gear 30 to rotate. When the second gear 30 rotates, its upper slide groove will drive the shift shaft 31 to move. The shift shaft 31 will drive the abutment plate 33 to move, which will play the role of inner circle clamping to prevent the target from falling off. The first motor 22 will drive the second drive shaft 23 to rotate, which will drive the fixed plate 27 fixedly connected to it to rotate, so that the scanner 20 can fully detect the meshing gap.
