Description

Technical Field

[0001] This utility model relates to the field of component testing technology, specifically a precision component testing device. Background Technology

[0002] Automobile manufacturing requires a vast number of precision parts, and the quality of the connections between these parts directly impacts the overall quality of the vehicle. Therefore, the quality of these parts is paramount. Since automobile parts are not manufactured in a single factory, each part undergoes quality inspection before assembly. Controlling part quality is crucial to ensuring the overall quality of the car. As a foundation for industries like automobiles and 3C (computer, communication, and consumer electronics), parts processing must guarantee safety and reliability. Strictly adhering to production dimensions is key to successful production. Machine vision technology utilizes computer vision to simulate human vision, acquiring, processing, and calculating images of physical objects for final inspection, control, and application. Surface defect detection is a vital part of machine vision inspection, and its accuracy directly affects the final quality of the product.

[0003] Currently, due to limitations in science and technology, the main method for detecting defects on the surface of products is still manual inspection. This method is slow and inefficient due to limitations in manpower and outdated technology. It is also prone to errors during the inspection process, resulting in inaccurate inspection results. Furthermore, it is not possible to put a batch of materials in at the same time during inspection; they must be put in sequentially, which is relatively troublesome and affects the efficiency of component inspection. Utility Model Content

[0004] Based on this, the purpose of this utility model is to provide a precision parts inspection device to solve the technical problems of slow speed, low efficiency and high limitations in manual product inspection.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a precision parts testing device, comprising a main body, a sliding material bin inside the main body, and a screening mechanism outside the sliding material bin. The screening mechanism includes a sliding block, a sliding plate, a second electric push rod, a welding frame, a rotating shaft, and a movable rod. The sliding block is fixed to one end of the sliding plate, the sliding plate is movably connected to the outside of the sliding material bin, the second electric push rod is disposed inside the main body, the welding frame is fixed inside the main body, the rotating shaft is disposed outside the sliding material bin, and the movable rod is movably connected to the outside of the sliding material bin.

[0006] A material distribution mechanism is provided on the outside of the material hopper. The material distribution mechanism includes a fixed frame, a first electric push rod, a fixed rod, a gear, a limiting ring, a material distribution plate, and a rotating rod. The fixed frame is fixed inside the main body, the first electric push rod is fixed inside the fixed frame, the fixed rod is located inside the material distribution plate, the gear is located outside the rotating rod, the limiting ring is located inside the main body, the material distribution plate is fixed on the fixed rod, and the rotating rod is located inside the main body.

[0007] By adopting the above technical solution, when in use, the power is turned on, and the external staff manually pour the same batch of nuts that need to be tested into the main body through the feed port set at the top of the main body. Then, the external control device starts the second electric push rod inside the main body, which makes it move up and down. Then, it will drive the sliding plate at one end to slide up and down.

[0008] While the second electric push rod is moving, it will drive the sliding plate fixed on the other side to move in the opposite direction around the rotating shaft via the fixed movable rod on its output end. At this time, the internal nut will vibrate under the action of the two sets of sliding plates, and at the same time, it will flip along one direction to prevent the number of nuts from being too large, which would cause the material cavity of the material hopper to be blocked.

[0009] After the nuts pass through the screening mechanism for screening, they slide through the sliding chamber inside the sliding bin and reach the distribution mechanism. The descending nuts are held in place by the distribution plate to prevent too many nuts from falling at the same time, which would result in poor detection. Then, the first electric push rod is activated, which drives the fixed rod at its output end to rise. The fixed rod then drives the distribution plate to separate the nuts.

[0010] When one of the material distribution plates rises, the toothed plate fixed at one end of the material distribution plate will move, causing the gear set on the rotating rod between the two material distribution plates to rotate, driving the other material distribution plate meshing with it to drive the transmission. At this time, by switching between the lifting and lowering of the two material distribution plates, a nut is released into the bottom end of the detection mechanism.

[0011] After the multiple sets of detection probes and nuts at the bottom of the detection mechanism perform the detection, the two sets of material plates are reset again by the first electric push rod.

[0012] Furthermore, the main body has an inlet at its top and an outlet at one end.

[0013] By adopting the above technical solution, the material inlet at the top of the main body facilitates material feeding by external personnel, and the material outlet controls the material discharge.

[0014] Furthermore, the main body is equipped with a detection device that cooperates with the material hopper, and a stabilizing frame for fixing the detection device is welded inside the main body.

[0015] By adopting the above technical solution, the limitations of manual feeding are greatly reduced during use. There is no need to manually release and pile up materials. Then, the detection device checks the effect of one material at a time, which ensures the detection effect and improves the detection efficiency.

[0016] Furthermore, the detection device is equipped with multiple sets of detection probes at its bottom, and the material hopper has a cavity that cooperates with the detection probes.

[0017] By adopting the above technical solution, the first electric push rod pushes the material distribution plate to rise while the gear drives the other material distribution plate that cooperates with it to fall, so that the detection probe at the bottom of the detection device located between the two material distribution plates can only detect one nut at a time, ensuring the detection effect.

[0018] Furthermore, the bottom of the material hopper is provided with multiple sets of support frames, and the support frames are connected to the main body by welding.

[0019] By adopting the above technical solution, multiple sets of support frames are used to prevent the material hopper from shaking during operation, which would affect the efficiency of subsequent inspections.

[0020] Furthermore, the sliding hopper has a sliding groove inside that cooperates with the sliding block, and a cavity on one side of the sliding hopper that cooperates with the material distribution plate.

[0021] By adopting the above technical solution, the second electric push rod is activated to drive the movable rod at its output end to sway around the axis of rotation, which drives the sliding plates on both sides to slide along the cavity set inside the outer side of the material hopper, and plays a certain limiting role.

[0022] In summary, this utility model has the following beneficial effects: The present utility model allows workers to directly pour the same batch of nuts to be tested into the feed inlet. A second electric push rod is activated, causing its output rod to vibrate around a pivot axis. This causes the sliding plates on both sides to slide along the cavity inside the outer side of the material storage bin, providing a certain limiting effect. The nuts are then propelled longitudinally into the pre-reserved slide rails inside the material storage bin by the vibration of the two sets of sliding plates, allowing them to slide until they reach one end of the distribution plate, where they are blocked. Then, the first electric push rod pushes the distribution plate upwards, while simultaneously driving another set of distribution plates that cooperates with it downwards via gears. This ensures that the detection probe at the bottom of the detection device located between the two sets of distribution plates can only detect one nut at a time, guaranteeing the detection effect and preventing a decrease in detection efficiency due to an excessive number of nuts.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] The embodiments of this utility model will be described below based on its overall structure.

[0032] A precision component testing device, such as Figure 1-6 As shown, the device includes a main body 1, inside which is a sliding hopper 9, and outside the sliding hopper 9 is a screening mechanism 6. The screening mechanism 6 includes a sliding block 601, a sliding plate 602, a second electric push rod 603, a welding frame 604, a rotating shaft 605, and a movable rod 606. External personnel manually pour the same batch of nuts to be inspected into the main body 1 through the inlet 2 at the top of the main body 1. Then, the second electric push rod 603 inside the main body 1 is activated by an external control device to make it move up and down. This will drive the sliding plate 602 at one end to slide up and down.

[0033] For example, the sliding block 601 is fixed to one end of the sliding plate 602, the sliding plate 602 is movably connected to the outside of the sliding chamber 9, the second electric push rod 603 is set inside the main body 1, the welding frame 604 is fixed inside the main body 1, the rotating shaft 605 is set outside the sliding chamber 9, and the movable rod 606 is movably connected to the outside of the sliding chamber 9. When the second electric push rod 603 moves, it will drive the sliding plate 602 fixed on the other side to move in the opposite direction with the rotating shaft 605 as the center through the movable rod 606 fixed on its output end. At this time, the nut inside will vibrate under the action of the two sets of sliding plates 602, and at the same time, it will flip along one direction to prevent the number of nuts from being too large, which would cause the sliding chamber of the sliding chamber 9 to be blocked.

[0034] For example, a material distribution mechanism 5 is provided on the outside of the sliding hopper 9. The material distribution mechanism 5 includes a fixed frame 501, a first electric push rod 502, a fixed rod 503, a gear 504, a limit ring 505, a material distribution plate 506, and a rotating rod 507. When the nut passes through the screening mechanism 6 for screening, it slides through the sliding cavity inside the sliding hopper 9 and reaches the material distribution mechanism 5. The descending nut is held in place by the material distribution plate 506 to prevent too many nuts from falling at the same time, which would result in poor detection effect. Then, the first electric push rod 502 is activated, which drives the fixed rod 503 at its output end to rise. The fixed rod 503 drives the material distribution plate 506 to separate the nuts.

[0035] In some examples, the fixing frame 501 is fixed inside the main body 1, the first electric push rod 502 is fixed inside the fixing frame 501, the fixing rod 503 is set inside the material distribution plate 506, the gear 504 is set outside the rotating rod 507, the limiting ring 505 is set inside the main body 1, and the material distribution plate 506 is fixed on the fixing rod 503. When one set of material distribution plates 506 rises, the toothed plate fixed at one end of the material distribution plate 506 will move, causing the gear 504 set on the rotating rod 507 between the two sets of material distribution plates 506 to rotate, driving the other set of material distribution plates 506 that meshes with it to perform transmission. At this time, by switching between the lifting and lowering of the two sets of material distribution plates 506, a nut is released into the bottom end of the detection mechanism 8.

[0036] For example, the rotating rod 507 is installed inside the main body 1. The top of the main body 1 has an inlet 2, and one end of the main body 1 has an outlet 3. The main body 1 is equipped with a detection device 8 that cooperates with the sliding hopper 9. A stabilizing frame for fixing the detection device 8 is welded inside the main body 1. After multiple sets of detection probes 7 with multiple nuts are installed at the bottom of the rear detection mechanism 8, the two sets of material plates 506 are reset again by the first electric push rod 502. Through the above structure, the limitations of manual feeding are greatly reduced during use, and there is no need to manually feed and stack materials. Then, the detection device 8 checks one material at a time, which ensures the detection effect and improves the detection efficiency.

[0037] The working principle of this utility model is as follows: When in use, the power is turned on, and the external staff manually pour the same batch of nuts that need to be tested into the main body 1 through the feed port 2 set at the top of the main body 1. Then, the external control device starts the second electric push rod 603 inside the main body 1, so that it moves up and down back and forth. Then, it will drive the sliding plate 602 at one end to slide up and down back and forth.

[0038] While the second electric push rod 603 is moving, it will drive the sliding plate 602 fixed on the other side to move in the opposite direction around the rotating shaft 605 via the fixed movable rod 606 on its output end. At this time, the internal nut will vibrate under the action of the two sets of sliding plates 602, and at the same time, it will flip along one direction to prevent the number of nuts from being too large, which would cause the material cavity of the material hopper 9 to be blocked.

[0039] After the nuts pass through the screening mechanism 6 for screening, they slide through the sliding chamber inside the sliding bin 9 and reach the distribution mechanism 5. The descending nuts are held in place by the distribution plate 506 to prevent too many nuts from falling at the same time, which would result in poor detection. Then, the first electric push rod 502 is started, which drives the fixed rod 503 at its output end to rise. The fixed rod 503 drives the distribution plate 506 to separate the nuts.

[0040] When one of the material distribution plates 506 rises, the toothed plate fixed at one end of the material distribution plate 506 will move, causing the gear 504 set on the rotating rod 507 located between the two material distribution plates 506 to rotate, driving the other material distribution plate 506 meshing with it to transmit power. At this time, through the conversion of the lifting and lowering of the two material distribution plates 506, a nut is released into the bottom end of the detection mechanism 8.

[0041] After the multiple sets of detection probes 7 and multiple nuts at the bottom of the detection mechanism 8 perform the detection, the two sets of material plates 506 are reset again by the first electric push rod 502.

[0042] The above structure achieves a high degree of freedom in manual feeding during use, eliminating the need for manual material feeding and stacking. Then, the detection device 8 checks one material at a time, ensuring the effectiveness of the detection and improving detection efficiency.
