Description

Technical Field

[0001] This utility model relates to the field of parts inspection racks, and in particular to a parallel inspection rack for multi-station equipment. Background Technology

[0002] The end faces of cylindrical metal parts such as bushings, bushings, and guide sleeves are typically used for axial positioning. Uneven end faces can lead to part skewing, uneven wear, or abnormal noise, thus requiring rigorous inspection for appearance defects such as flatness, dents, and scratches. However, during the manufacturing process, oil stains, cutting fluid residue, and other contaminants inevitably adhere to the end faces. These contaminants severely interfere with visual inspection of the end faces, affecting the accuracy of the inspection results.

[0003] In existing technologies, manual cleaning of the end faces of parts is typically performed during visual inspection. This approach has significant drawbacks: it greatly increases labor costs and has low manual cleaning efficiency. This inefficient manual cleaning step cannot meet the high-speed flow requirements of multi-station inspection racks, becoming a bottleneck in the entire inspection process and severely restricting the overall inspection efficiency of the racks. Utility Model Content

[0004] To overcome the shortcomings of existing technologies, the purpose of this utility model is to provide a multi-station parallel inspection rack that solves the problem that traditional inspection racks cannot clean the end faces of cylindrical metal parts.

[0005] To address the problems in the existing technology, the technical solution of this utility model is as follows:

[0006] A multi-station parallel inspection rack includes a machine base, on the top surface of which a station turntable is rotatably mounted. Multiple clamping components are fixed at equal angular intervals on the top surface of the station turntable for clamping the parts to be inspected. The rotation of the station turntable drives the clamping components to clamp the parts through a vision inspection device to complete the appearance inspection of the workpiece.

[0007] The machine tool is also equipped with a cleaning component. As the turntable rotates, the parts pass through the cleaning component and are cleaned before being inspected.

[0008] Optionally, the clamping assembly includes a first servo motor fixed on the workstation turntable. The output end of the first servo motor is fixed with a first rotating shaft, which is rotatably connected to the top surface of the workstation turntable through a bearing. A clamp is fixed at the end of the first servo motor away from the first servo motor, and the clamp is located on the periphery of the workstation turntable.

[0009] Optionally, the cleaning assembly includes a cleaning box fixed to the outer wall of one side of the machine for holding cleaning fluid. A conveyor device is slidably installed inside the box. A conveyor belt with a cleaning felt is sleeved on the outside of the conveyor device. The inner cavity of the conveyor belt faces the outer wall of the machine. The conveyor device drives the conveyor belt to circulate, so that the cleaning felt moves between the bottom and top of the cleaning box. An elastic element is provided between the conveyor device and the cleaning box so that the conveyor device always has an upward tendency. A push component on the workstation turntable presses down on the conveyor device when the clamping component approaches the conveyor device. When the workpiece moves above the cleaning felt, the push component is released, and the elastic element pushes the conveyor device upward so that the cleaning felt contacts the outer wall of the workpiece. Brush bristles are fixed at equal intervals on the bottom surface of the inner wall of the cleaning box, and the brush bristles abut against the outer wall of the cleaning felt.

[0010] Optionally, the conveying device includes a lifting frame that is slidably connected to the inner wall of the cleaning box. Each of the four corners of the lifting frame is rotatably connected to a drive roller via bearings. The conveyor belt is sleeved on the outer wall of the four drive rollers. A second servo motor is fixed to the upper end of the lifting frame on the side away from the machine platform. The end of a drive roller facing the second servo motor is fixed to the output end of the second servo motor. A squeegee is fixed to one side of the lifting frame, and one side of the squeegee abuts against the outer wall of the cleaning felt.

[0011] Optionally, slide rails are symmetrically fixed on the inner walls of opposite sides of the cleaning box, and slide bars are symmetrically fixed on the outer walls of opposite sides of the lifting frame. The slide bars are slidably connected to the outer wall of one of the slide rails, and a limit block is fixed at the top of the slide rail. The elastic element includes springs symmetrically fixed on the inner wall of the cleaning box. The upper end of the spring is fixed to the outer wall of the lifting frame. When the lifting frame is in the uppermost position, the slide bar abuts against the bottom surface of the limit block.

[0012] Optionally, the jacking assembly includes a jacking column fixed to the bottom surface of the workstation turntable. The jacking column has a circular cross-section. A drive plate is fixed to the top surface of the lifting frame near the workstation turntable. The drive plate is arc-shaped, with both ends of the drive plate bent downwards. When the slide bar touches the bottom surface of the limiting block, the jacking column rotates and approaches the outer wall of the bent portion of the drive plate directly opposite the end of the drive plate.

[0013] Compared with the prior art, the advantages of this utility model are as follows:

[0014] In the process of inspecting cylindrical metal parts, this utility model can automatically clean the end face of the parts by using a cleaning felt during the rotation of the station turntable to load, inspect, and unload the metal parts. This ensures the cleanliness of the end face of the parts during visual inspection, avoids the impact of stains on the inspection results, and the cleaning process is fully automated without human intervention, resulting in higher cleaning efficiency, more stable cleaning effect, and significant savings in labor costs.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] Please see Figures 1 to 6 This embodiment provides a multi-station parallel testing rack, including a machine base 1. A station turntable 2 is rotatably mounted on the top surface of the machine base 1. The station turntable 2 is driven to rotate by a rotating device installed in the machine base 1. This multi-station turntable 2 structure arrangement is a mature existing technology.

[0024] Four first servo motors 3 are fixed at equal angular intervals on the top surface of the workstation turntable 2. The output end of the first servo motor 3 is fixed with a first rotating shaft 4, which is rotatably connected to the top surface of the workstation turntable 2 through bearings. A clamp 5 is fixed at the end of the shaft that is away from the first servo motor 3. The clamp 5 is located on the periphery of the workstation turntable 2. The clamp 5 is a cylindrical clamp 5. The corresponding clamp 5 can be replaced according to the characteristics of the part to be tested. The clamp 5 is a mature existing technology, so it will not be described in detail. The four sides of the machine 1 are the loading station, cleaning station, inspection station and unloading station, respectively. The multi-station setting greatly improves the inspection efficiency.

[0025] The specific process of the multi-station workstation is as follows: First, at the loading station, the worker or robotic arm places the part to be tested on the fixture 5. The fixture 5 holds the workpiece, and it is necessary to ensure that the fixture 5 is held at the middle position of the height of the cylindrical fixture 5, that is, the part finally extends the same distance on both the top and bottom sides of the fixture 5. Then, the station turntable 2 is driven to rotate, so that the part passes through the cleaning station, the inspection station and finally the unloading station in sequence. If it is necessary to complete the inspection of two end faces at one time on one machine, the part is not unloaded when it reaches the unloading station. Instead, the first servo motor 3 drives the first rotating shaft 4 to rotate 180 degrees, so that the fixture 5 is rotated 180 degrees, so that the workpiece is flipped. Then, the visual inspection of the second end face is continued.

[0026] The visual inspection equipment is located on the outside of the machine tool 1, and usually includes a bracket and an industrial camera fixed on the bracket. The industrial camera is used to inspect the cross-section of the parts. This is a mature existing technology and will not be elaborated here.

[0027] The cleaning work at the cleaning station is accomplished through the following structural arrangement: a cleaning box 6 is fixed to the outer wall of one side of the machine 1, and the cleaning box 6 is filled with cleaning solution during use. A lifting frame 7 is slidably connected to the inner wall of the cleaning box 6. Slide rails 8 are symmetrically fixed to the inner walls of opposite sides of the cleaning box 6, and slide bars 9 are symmetrically fixed to the outer walls of opposite sides of the lifting frame 7. The slide bars 9 are slidably connected to the outer wall of the opposite slide rail 8, realizing the sliding connection between the lifting frame 7 and the cleaning box 6. A limit block 10 is fixed to the top of the slide rail 8 to limit the highest position of the lifting frame 7 inside the cleaning box 6. After the slide bar 9 touches the limit block 10, it cannot continue to slide upward.

[0028] Springs 11 are symmetrically fixed to the inner wall of the cleaning box 6. The upper end of the springs 11 is fixed to the outer wall of the lifting frame 7. When the lifting frame 7 is in the uppermost position, the slide bar 9 abuts against the bottom surface of the limiting block 10. The springs 11 provide the lifting frame 7 with a force that always has an upward sliding tendency.

[0029] The four corners of the lifting frame 7 are rotatably connected to drive rollers 12 via bearings. The conveyor belt 13 is sleeved on the outer wall of the four drive rollers 12. The outer wall of the conveyor belt 13 is sleeved and fixed with cleaning felt 14. The upper end of the lifting frame 7 on the side away from the machine base 1 is fixed with a second servo motor 15. The end of one drive roller 12 facing the second servo motor 15 is fixed to the output end of the second servo motor 15.

[0030] The lower part of the cleaning felt 14 is below the surface of the cleaning liquid in the cleaning tank 6. The cleaning felt 14 is cleaned by soaking it in the cleaning liquid. When the cleaned felt 14 needs to be conveyed to the top, the second servo motor 15 is driven to rotate the drive roller 12, which in turn causes the conveyor belt 13 to convey the felt 14. This ensures that the cleaned felt 14 is continuously conveyed to the top of the lifting frame 7. A squeegee 18 is fixed to one side of the lifting frame 7, and one side of the squeegee 18 abuts against the outer wall of the cleaning felt 14. Brush bristles 19 are fixed at equal intervals on the bottom surface of the inner wall of the cleaning tank 6, and the brush bristles 19 abut against the outer wall of the cleaning felt 14. During the conveyor belt 13, the cleaning felt 14 moves continuously and is automatically brushed by the brush bristles 19. It is effectively cleaned by the brush bristles 19 and then the water is scraped off by the squeegee 18, ensuring the dryness of the cleaning felt 14 that rises to the top of the lifting frame 7 and avoiding excessive water retention.

[0031] In the initial state, that is, the slider 9 is pressed against the bottom surface of the limit block 10 under the action of the spring 11. At this time, the station turntable 2 rotates, causing the clamped workpiece to move. However, the bottom surface of the workpiece is slightly lower than the top surface of the cleaning felt 14. Therefore, it is necessary to use the push structure to push the lifting frame 7 down until the workpiece moves above the cleaning felt 14 and then release the lifting frame 7, so that the cleaning felt 14 is pressed against the bottom surface of the workpiece. The push structure is set as follows:

[0032] A push column 16 is fixed on the bottom surface of the workstation turntable 2. The cross-section of the push column 16 is circular. A drive plate 17 is fixed on the top surface of the lifting frame 7 near the workstation turntable 2. The drive plate 17 is arc-shaped and its two ends bend downwards.

[0033] When the slider 9 contacts the bottom surface of the limiting block 10, the push column 16 rotates and approaches the outer wall of the bent portion of the drive plate 17 directly opposite the end of the drive plate 17. Thus, when the workpiece approaches the cleaning felt 14, the push column 16 pushes the drive plate 17, causing the drive plate 17 to slide the lifting frame 7 downwards. This continues until the workpiece reaches above the cleaning felt 14. Then, the push column 16 moves away from the drive plate 17, and the lifting plate rises, causing the cleaning felt 14 to contact the bottom surface of the workpiece. At this time, the slider also contacts the bottom surface of the limiting block 10. The cleaning felt 14 is only slightly deformed by the workpiece pressure. The workpiece continues to be rotated and slide past the cleaning felt 14 by the station turntable 2, effectively wiping and cleaning it, removing material from the workpiece end face, improving the accuracy of the test results, and eliminating the need for manual cleaning, saving manpower and significantly improving efficiency.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
