Description

Technical Field

[0001] The utility model relates to the technical field of detection devices, in particular to a high-precision mechanical part detection device. Background Technique

[0002] Mechanical parts, also known as mechanical elements, are the basic elements that make up a machine and are indivisible single components that make up a machine. Surface roughness is an important technical indicator that reflects the microscopic geometric shape error of a part's surface and is the main basis for inspecting the surface quality of a part; whether it is reasonably selected directly affects the quality, service life, and production cost of the product. High-precision mechanical parts are a type of mechanical parts with fine surface roughness. During the processing of high-precision mechanical parts, a polishing device is required to grind the surface of the mechanical parts to make it flat, thereby improving the precision of the mechanical parts. After being polished, the high-precision mechanical parts need to use a detection device to observe whether there are defects on the surface of the high-precision mechanical parts.

[0003] Currently, when detecting high-precision mechanical parts, they are usually placed at a high-precision mechanical part detection device for taking pictures to observe whether there are defects on the surface. Although this can detect high-precision mechanical parts, there will be some dust adhering to the surface of the polished high-precision mechanical parts. The dust adhering to the surface of the high-precision mechanical parts will make the surface of the high-precision mechanical parts of the detection device not flat and smooth enough, thus affecting the detection results of the high-precision mechanical parts.

[0004] Therefore, those skilled in the art have provided a high-precision mechanical part detection device to solve the problems raised in the above background technique. Content of the Utility Model

Specific implementation mode

[0021] Please refer to Figures 1 to 5 , in the embodiment of the present utility model, a high-precision mechanical component detection device includes a workbench 1 and a conveyor belt 2 fixedly arranged on the workbench 1. A guiding and clamping component is arranged on the workbench 1. A dust cleaning component is arranged on one side of the guiding and clamping component. A component detection component is arranged on one side of the dust cleaning component. The guiding and clamping component can center the mechanical components on the conveyor belt 2. The dust cleaning component can sweep the dust on the mechanical components to both sides of the mechanical components. The component detection component is used to detect whether there are defects on the surface of the mechanical components.

[0022] The dust cleaning component includes a first U-shaped frame 3 and a second U-shaped frame 4 fixedly arranged on the workbench 1. The positions of the first U-shaped frame 3 and the second U-shaped frame 4 correspond to each other. A connecting plate 5 is fixedly arranged between the first U-shaped frame 3 and the second U-shaped frame 4. A rotating disk 6 is rotatably connected to the connecting plate 5. A limiting rod 7 is fixedly arranged on the rotating disk 6. A swing plate 8 is rotatably connected to the second U-shaped frame 4. A limiting groove 9 is formed on the swing plate 8. The limiting rod 7 is slidably connected in the limiting groove 9. A connecting rod 10 is fixedly connected to the swing plate 8. A guiding opening 11 is formed on the first U-shaped frame 3. One end of the connecting rod 10 away from the swing plate 8 passes through the guiding opening 11, and a dust cleaning brush 12 is fixedly arranged at the end of the connecting rod 10 passing through the guiding opening 11. A driving motor 13 is fixedly arranged on the connecting plate 5. The output end of the driving motor 13 is docked with the rotating disk 6.

[0023] In this embodiment, when the mechanical parts on the conveyor belt 2 are conveyed to the dust cleaning component, the driving motor 13 is started. The start of the driving motor 13 drives the rotating disk 6 to rotate. The rotation of the rotating disk 6 drives the swing plate 8 to swing back and forth. The swing of the swing plate 8 drives the dust cleaning brush 12 to swing back and forth along the guiding opening 11 through the connecting rod 10. The swing of the dust cleaning brush 12 will sweep the dust on the mechanical parts, and the swept dust is located on both sides of the mechanical parts.

[0024] Through the setting of the dust cleaning component, not only can the dust on the surface of the mechanical parts to be detected be cleaned, so as to avoid affecting the detection result due to too much dust on the surface of the mechanical parts, but also by sweeping the dust on the surface of the mechanical parts to both sides, the dust on the surface of the mechanical parts can be cleaned in time, avoiding the problem that there is a large accumulation of dust on the dust cleaning brush 12 due to continuous dust treatment of the surface of the mechanical parts, resulting in insufficient cleaning of the dust on the surface of the mechanical parts.

[0025] The guiding and clamping assembly includes two fixed frames 14 fixedly connected to the workbench 1. The two fixed frames 14 are located on both sides of the conveyor belt 2. A gear 15 is rotatably connected inside the fixed frame 14. A pushing plate 16 is arranged on the fixed frame 14. The pushing plate 16 passes through the fixed frame 14. Transmission teeth 17 are formed on the pushing plate 16. The transmission teeth 17 mesh with the gear 15 inside the fixed frame 14. A connecting frame 18 is fixedly arranged on the two fixed frames 14. A servo motor 19 is fixedly arranged on the connecting frame 18. Two transmission members 20 are rotatably connected to the connecting frame 18. The output end of the servo motor 19 is docked with one transmission member 20. The two transmission members 20 are connected through a connection. Transmission rods 21 are arranged on the transmission members 20. One ends of the two transmission rods 21 far away from the transmission members 20 are respectively docked with the transmission teeth 17 inside the two fixed frames 14. Rotating rollers 24 are connected to opposite ends of the two pushing plates 16.

[0026] In this embodiment, first, the servo motor 19 is started according to the width of the mechanical component to be detected. The start of the servo motor 19 drives the transmission member 20 docked with its output end to rotate. The rotation of the transmission member 20 drives another transmission member 20 to rotate through a belt. The rotation of the transmission member 20 drives the gear 15 to rotate through the transmission rod 21. The rotation of the gear 15 drives the pushing plate 16 to move parallel to the conveyor belt 2. The movement of the pushing plate 16 drives the roller 24 to move. When the distance between the two rollers 24 is adapted to the width of the mechanical component to be detected, the servo motor 19 will be turned off. When the mechanical component to be detected passes through the guiding and clamping assembly, the two rollers 24 clamp the outer wall surface of the mechanical component to be detected.

[0027] Through the setting of the guiding and clamping assembly, not only can the distance for clamping the mechanical component to be detected be adjusted according to the width of the mechanical component to be detected, thereby improving the range of mechanical components applicable to the device, but also the mechanical components on the conveyor belt 2 can be centered, so that when the mechanical components are conveyed to the component detection assembly, they are just directly below the component detection assembly, thereby making the detection of the mechanical components more accurate.

[0028] The component detection assembly includes a support frame 22 fixedly connected to the workbench 1. A component detection head 23 is fixedly arranged on the support frame 22. The component detection head 23 is located on the center line of the conveyor belt 2. The support frame 22 plays a role in supporting the component detection head 23. The component detection head 23 is used to take pictures of the mechanical components on the conveyor belt 2. The taken pictures will be transmitted to a computer, and the taken pictures are analyzed by the computer or manually to determine whether there are defects in the mechanical components.

[0029] The working principle of the present utility model is:

[0030] First, start the servo motor 19 according to the width of the mechanical part to be detected. The start of the servo motor 19 drives the transmission part 20 connected to its output end to rotate. The rotation of the transmission part 20 drives another transmission part 20 to rotate through the belt. The rotation of the transmission part 20 drives the gear 15 to rotate through the transmission rod 21. The rotation of the gear 15 drives the pushing plate 16 to move parallel to the conveyor belt 2. The movement of the pushing plate 16 drives the roller 24 to move. When the distance between the two rollers 24 is adapted to the width of the mechanical part to be detected, the servo motor 19 will be started and then turned off. Then, place the mechanical part to be detected on the conveyor belt 2. When the mechanical part to be detected passes through the guiding and clamping assembly, the two rollers 24 clamp on the outer wall surface of the mechanical part to be detected, so as to center the mechanical part to be detected on the conveyor belt 2. When the mechanical part on the conveyor belt 2 is conveyed to the dust cleaning assembly, start the driving motor 13. The start of the driving motor 13 drives the rotating disk 6 to rotate. The rotation of the rotating disk 6 drives the swing plate 8 to swing back and forth. The swing of the swing plate 8 drives the dust cleaning brush 12 to swing back and forth along the guiding port 11 through the connecting rod 10. The swing of the dust cleaning brush 12 will clean the dust on the mechanical part, and the cleaned dust is located on both sides of the mechanical part. When the mechanical part is conveyed to the part detection assembly, the part detection head 23 takes a photo of the mechanical part on the conveyor belt 2. The taken photo will be conveyed to the computer, and the taken photo is analyzed by the computer or manually to judge whether there are defects in the mechanical part.

Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and should be covered within the protection scope of the present invention.
