Description
Technical Field
[0001] This utility model relates to the field of testing device technology, and in particular to a novel component surface precision testing device. Background Technology
[0002] Most mechanical equipment is assembled from various precision mechanical parts. The dimensional accuracy and quality requirements of these parts are high. After the parts are manufactured, they need to be inspected to ensure their quality and dimensional accuracy, and to prevent unqualified parts from entering the market and affecting the quality of the assembled mechanical equipment.
[0003] However, in practical use, the existing component surface inspection devices still have the following technical problems:
[0004] From a structural design perspective, some existing component inspection devices lack specialized structures that can achieve component rotation. They mostly adopt simple fixed inspection modes, which can only inspect the exposed top and side surfaces of components. During inspection, the components are fixed in a single position without any mechanical components that can drive them to rotate, resulting in the bottom always being in the inspection blind zone. This makes the inspection results severely biased and unable to fully reflect the overall surface accuracy of the components. There are significant loopholes in the quality control of components, making it difficult to meet the stringent requirements of modern manufacturing for high-precision, all-round inspection.
[0005] In response to this technical problem, this application proposes a novel component surface precision inspection device. Utility Model Content
[0006] The purpose of this invention is to address the shortcomings of existing technologies by proposing a novel component surface precision inspection device. This device utilizes a transmission assembly and circular gears to flip components from the right end of the conveyor belt to the left end for bottom inspection, greatly improving the comprehensiveness of the inspection and compensating for blind spots in traditional devices. Simultaneously, the motor drives a bevel gear in conjunction with a screw, the clamping plate can adapt to components of different sizes, and the inner protective pad ensures inspection accuracy.
[0007] To achieve the above objectives, the present invention provides the following technical solution:
[0008] A novel surface precision inspection device for parts includes a housing. A motor is fixedly connected to the top side of the inner wall of the housing. The motor is connected to a vision inspection device via a sliding assembly. An operating table is fixedly connected to the front side of the inner wall of the housing. The operating table is connected to a rack via a transmission assembly. A circular gear is meshed with the top of the rack. The circular gear is connected to the top of the operating table via a fixing plate. A connecting block is fixedly connected to the rear side of the circular gear. A limit rod is fixedly connected to the front right side of the connecting block. A screw is rotatably connected to the right end of the connecting block. The right end of the screw is rotatably connected to the right side of the inner wall of the limit rod. A clamping plate is threaded to the outer side of the screw. A second motor is fixedly connected to the top of the connecting block. The driving end of the second motor passes through the top of the connecting block and is fixedly connected to a bevel gear. The bevel gear meshes with the screw. The rear side of the connecting block is connected to the inner wall of the housing via a shaft. A conveyor belt is installed at the bottom inside the housing. The conveyor belt is connected to a mounting surface via a mounting assembly.
[0009] Furthermore, an observation window is provided on the front side of the outer wall of the housing.
[0010] Furthermore, the sliding assembly includes two fixed blocks, which are fixedly connected to the top of the inner wall of the housing. A lead screw is rotatably connected to the adjacent side of the two fixed blocks, and a slider is threadedly connected to the outer side of the lead screw. A visual inspection device is fixedly connected to the bottom of the slider.
[0011] Furthermore, the lead screw is fixedly connected to one drive end of the motor, and the top side of the inner wall of the housing is in contact with the top of the slider and limits its movement.
[0012] Furthermore, the transmission assembly includes a slide groove, which is located at the rear end of the top of the operating table. A telescopic rod is fixedly connected to the left side of the inner wall of the slide groove, and a rack is fixedly connected to the right end of the telescopic rod.

[0016] This utility model has the following beneficial effects:
[0017] This invention significantly improves the comprehensiveness of inspection: through the unique transmission component 7 and the circular gear 10, the parts clamped by the clamping plate 17 can be flipped from the right end to the left end of the conveyor belt 21, so that the bottom of the parts is facing upwards, thus enabling the inspection of the bottom of the parts. This effectively makes up for the blind spots of traditional devices and greatly improves the comprehensiveness of inspection.
[0018] In this invention, a motor drives a bevel gear and a screw to work together, allowing the clamping plate to flexibly adjust its opening and closing degree according to the size of the parts. This ensures stable clamping of both large and small precision components.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0027] Reference Figure 1 , Figure 2 and Figure 5This utility model provides an embodiment of a novel component surface precision inspection device, comprising a housing 1, which serves as the external frame of the entire device, protecting the internal components and providing a mounting base. A motor 2 is fixedly connected to the top side of the inner wall of the housing 1. The motor 2 is connected to a vision inspection device 4 via a sliding assembly 3. During operation, the motor 2 starts, driving the lead screw 302 to rotate. Due to the threaded connection between the lead screw 302 and the slider 303, and the limitation of the slider 303 by the housing 1, the slider 303 moves linearly along the lead screw 302, thereby moving the vision inspection device 4. This structure allows the vision inspection device 4 to flexibly adjust its position, enabling comprehensive and precise inspection of component surfaces at different locations. To improve the coverage and accuracy of the detection, an operating table 6 is fixedly connected to the front side of the inner wall of the housing 1. The operating table 6 is connected to the rack 8 through the transmission assembly 7. A circular gear 10 is meshed with the top of the rack 8. The circular gear 10 is connected to the top of the operating table 6 through the fixing plate 11. A connecting block 12 is fixedly connected to the rear side of the circular gear 10. When the rack 8 moves under the action of the telescopic rod 702, the circular gear 10 meshing with the rack 8 will rotate accordingly, thereby driving the connecting block 12 to rotate. The key function of the rotation of the circular gear 10 is that the screw 15 connected to the right end of the connecting block 12 is threaded with a clamping plate 17. The clamping plate 17 will clamp the parts conveyed from the right end of the conveyor belt 21. As the circular gear 10 drives the connecting block 12 to rotate, the connecting block 12 rotates. The component clamped by the clamping plate 17 can be flipped from the right end to the left end of the conveyor belt 21, so that the bottom of the component, which was originally facing upwards, is now facing upwards. This enables the detection of the bottom of the component, effectively solving the problem that traditional detection devices have difficulty detecting the bottom of components and greatly improving the comprehensiveness of the detection. The front right side of the connecting block 12 is fixedly connected to a limit rod 16, and the right end of the connecting block 12 is rotatably connected to a screw 15. The right end of the screw 15 is rotatably connected to the right side of the inner wall of the limit rod 16, and the outside of the screw 15 is threadedly connected to the clamping plate 17. The top of the connecting block 12 is fixedly connected to a second motor 13, and the driving end of the second motor 13 passes through the top of the connecting block 12 and is fixedly connected to a bevel gear 14. The bevel gear 14 meshes with the screw 15. When the second motor 13 starts, the driving end... The bevel gear 14 is driven to rotate. Due to the meshing of the bevel gear 14 and the screw 15, the screw 15 rotates under the limit of the limiting rod 16, which in turn causes the threaded clamping plate 17 to move linearly along the screw 15, realizing the clamping and loosening operation of the parts. This structure can accurately and stably clamp and fix parts of different sizes, ensuring that the parts will not be displaced during the inspection process, and ensuring the accuracy of the inspection results. The rear side of the connecting block 12 is connected to the inner wall of the housing 1 through the shaft 18. The shaft 18 provides a stable support point for the rotation of the connecting block 12, making the rotation of the connecting block 12 more stable. A conveyor belt 21 is installed at the bottom of the inside of the housing 1. The conveyor belt 21 is connected to the mounting surface through the mounting assembly 9. When the conveyor belt 21 is working...The rotation of roller 901 drives the conveyor belt 21, automatically transporting parts to the inspection area.
[0028] Reference Figures 2-4 An observation window 5 is provided on the front side of the outer wall of the housing 1. Operators can directly observe the inspection status of the internal components of the housing 1 through the observation window 5, reducing the interference of the external environment on the internal inspection. It also facilitates the timely detection of abnormalities during equipment operation, such as whether the components are correctly placed or whether the inspection equipment is working properly. The beneficial effect is to improve the convenience of operation and the monitorability of the inspection process, ensuring the smooth progress of the inspection work. The sliding component 3 includes two fixed blocks 301, which are fixedly connected to the top of the inner wall of the housing 1. A lead screw 302 is rotatably connected to the side of the two fixed blocks 301 that is close to each other. A slider 303 is threadedly connected to the outside of the lead screw 302. A vision inspection device 4 is fixedly connected to the bottom of the slider 303. The lead screw 302 is fixedly connected to the drive end of the motor 2. The top side of the inner wall of the housing 1 is in contact with the top of the slider 303 and limits its movement. The transmission component 7 includes a slide groove 701, which is opened at the rear end of the top of the operating table 6. A telescopic rod is fixedly connected to the left side of the inner wall of the slide groove 701. 702, a rack 8 is fixedly connected to the right end of the telescopic rod 702, providing variable power input for subsequent meshing transmission with the circular gear 10, facilitating adjustment of the rotation angle of the connecting block 12. The rack 8 is slidably connected inside the slide groove 701. A protective sleeve 19 is rotatably connected to the outside of the shaft 18. During the rotation of the connecting block 12 around the shaft 18, the protective sleeve 19 can reduce the friction and collision between the shaft 18 and the parts, preventing damage to the surface of the parts, while ensuring the stability of the rotation of the connecting block 12. A protective pad 20 is fixedly connected to the inner side of the clamping plate 17. When the clamping plate 17 clamps the parts, the protective pad 20 can increase the friction force, preventing the parts from slipping, while avoiding direct contact between the clamping plate 17 and the surface of the parts, causing scratches, damage, etc., ensuring the integrity and surface quality of the parts during the inspection process. The mounting component 9 includes a roller 901, which is installed on the left and right ends of the inner wall of the conveyor belt 21. Support columns 902 are fixedly connected to the front and rear sides of the roller 901, and the bottom of the support column 902 is fixedly connected to the mounting surface.
[0029] Working principle: After the device is started, the conveyor belt 21 at the bottom of the housing 1 rotates through the roller 901 of the mounting assembly 9, transporting the parts from the right end to the inspection area. In the initial state, the rack 8 is in the middle of the slide groove 701 at the rear end of the top of the operating table 6, and the screw 15 of the clamping plate 17 on the connecting block 12 is perpendicular to the conveyor belt 21. When the conveyor belt 21 transports the parts to the inspection area, the telescopic rod 702 on the left side of the inner wall of the slide groove 701 in the transmission assembly 7 retracts to the left, pushing the rack 8 to slide in the slide groove 701, driving the circular gear 10 meshing with it to rotate, thereby causing the connecting block 12 to rotate, allowing the clamping plate 17 to rotate to an angle parallel to the conveyor belt 21. At this time, the motor 13 at the top of the connecting block 12 starts, and the drive end drives the bevel gear 14 to rotate, causing the screw 15 to rotate, controlling the clamping plate 17 to clamp the parts after the top surface inspection is completed. Then... The telescopic rod 702 is pushed to the right to the right side of the inner wall of the slide groove 701, which drives the rack 8 to move again, causing the circular gear 10 to continue to rotate. The clamping plate 17 also rotates 180°, causing the parts to flip up to the bottom. At the same time, the motor 2 on the top side of the inner wall of the housing 1 drives the lead screw 302 to rotate, causing the slider 303 and the visual inspection device 4 fixedly connected to the bottom to move to the left to the top of the parts to inspect the bottom of the parts. During the entire inspection process, the operator can monitor through the observation window 5 on the front side of the outer wall of the housing 1. The protective sleeve 19 on the outside of the shaft 18 can reduce the friction and collision between the shaft 18 and the outside, ensuring the stability of the rotation of the connecting block 12. The protective pad 20 on the inside of the clamping plate 17 increases the friction to prevent the parts from slipping and avoids the clamping plate 17 from directly contacting the surface of the parts and causing damage, ensuring the integrity and surface quality of the parts during the inspection process.
[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
