Abstract
Description
Technical Field
[0001] This utility model relates to the field of automotive parts inspection technology, specifically to an inspection and feeding mechanism for automotive outer tubes. Background Technology
[0002] Engine connecting rod bushings are fitted into the small end bore of the connecting rod. Typically, these bushings are rolled copper open bushings with a wall thickness of approximately [thickness missing], although machined open bushings are also possible. During assembly, they are compressed and inserted into the small end bore of the connecting rod, forming an interference fit. During operation, the assembled bushing forms a clearance fit with the piston pin. With lubrication, this reduces friction between workpieces at high speeds, improving engine lifespan. The use of bushings in connecting rod assemblies has become mainstream in this field. However, the outer diameter of the bushing is crucial to the fit between the bushing and the small end bore of the connecting rod. An excessively large outer diameter can damage both the bushing and the connecting rod during insertion, potentially leading to failure. An excessively small outer diameter will cause the bushing to rotate or fall out of the small end bore. Therefore, employing appropriate testing methods to determine if the connecting rod bushing's outer diameter meets technical requirements is essential. Bushing loading is necessary, and current technology typically uses manual loading. However, manual loading is inefficient, labor-intensive, and detrimental to production cost control.
[0003] Existing technology, such as publication number CN217167632U, provides a bushing production feeding machine, relating to the field of automotive parts production technology. It includes a hopper, with a roller conveyor connected to the upper end of one side of the hopper, and a detection mechanism connected to the lower end of the roller conveyor. A partition is installed inside the hopper, dividing it into an upper feeding bin and a lower conveying bin. Bushings are placed in the feeding bin, and a lifting mechanism is installed in the conveying bin. The lifting mechanism includes a first cylinder fixedly installed at the bottom of the hopper, with a piston rod extending through the bottom of the hopper into the conveying bin. A feeding plate is connected to the piston rod, and the top of the feeding plate is inclined. This invention, by setting up a lifting mechanism, achieves automatic bushing feeding without manual operation, saving time and effort and facilitating cost control. The feeding machine only requires workers to place the bushings into the hopper, and the first cylinder operates to transport the bushings one by one to the roller conveyor, where they enter the detection mechanism for inspection.
[0004] The existing solution achieves automatic bushing feeding through a lifting mechanism, eliminating the need for manual operation, saving time and labor, and facilitating cost control. The feeding machine only requires workers to place the bushings into the hopper; the first cylinder then transports the bushings one by one to the roller conveyor. After passing through the roller conveyor, they enter the inspection mechanism for testing. Qualified products are then picked up and used by a robotic arm. However, in actual use, due to insufficient lifting bushings, the roller conveyor becomes disorganized and inconsistently positioned, significantly increasing the difficulty of robotic arm handling. Furthermore, parts falling during the lifting process may be damaged by impacts. Therefore, we propose a new inspection and feeding mechanism for automotive outer tubes. Utility Model Content
[0005] The purpose of this utility model is to provide a detection and feeding mechanism for automotive outer tubes. This mechanism solves the problem that the lack of lifting bushings in actual use leads to disorder and inconsistent positions in the roller conveyor, which greatly increases the difficulty of positioning.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] A detection and feeding mechanism for automotive outer tubes includes a top material box, an inclined material hopper is provided on the inner wall of the top material box, a first top platform is slidably connected to the lowest point of the inclined material hopper, a second top platform is slidably connected to the inner wall of the inclined material hopper above the first top platform, and a third top platform is fixedly connected to the top of the top material box above the second top platform.
[0008] A storage platform is fixedly connected to the inner wall of the inclined material hopper at the position corresponding to the second top platform. The bottom of the second top platform and the first top platform are fixedly connected by a connecting plate. The inside of the top material box is equipped with a first cylinder for lifting the connecting plate.
[0009] Preferably, the first top platform, the second top platform, and the third top platform are arranged in a stepped manner, and the height intervals between them are consistent.
[0010] Preferably, the tops of the first top platform, the second top platform, the third top platform, and the storage platform are all sloped, and the angle of the slope is the same as the angle of the bottom slope of the sloping material silo.
[0011] Preferably, a conveyor belt is fixedly connected to the outside of the top material box via an mounting plate, and a discharge bin is fixedly connected to one side of the conveyor belt.
[0012] Preferably, the third top platform has a notch on the side near the discharge bin, and a straightening baffle is fixedly connected above the conveyor belt at the position corresponding to the notch.
[0013] Preferably, a positioning platform is provided on one side of the discharge bin for positioning the bushing for detection, and a discharge port is provided in the discharge bin corresponding to the position of the positioning platform.
[0014] Preferably, a linear guide rail is fixedly connected to the top of the positioning platform, a second cylinder is slidably connected to the top of the linear guide rail, a support plate is fixedly connected to the telescopic end of the second cylinder, and a plurality of claws are fixedly connected to the support plate, with consistent spacing between the claws.
[0015] By employing the above technical solution, this utility model provides a detection and feeding mechanism for automotive outer tubes. It possesses at least the following beneficial effects:
[0016] I. This utility model uses a storage platform to lift the bushing in multiple stages during the lifting process, reducing the height of each lift and preventing excessive drop during the lifting process, which could cause damage due to excessive impact.
[0017] II. When the bushing slides down to the top of the third top platform, it will slide along the inclined surface of the third top platform to the top of the conveyor belt. The conveyor belt will transport the bushings to the discharge bin for queuing. Since the diameter of the bushing is longer than its height, the gap below the straightening baffle is just enough to allow the straightened bushings to pass through. When the tilted bushings pass through the straightening baffle, some will be pushed down and straightened. The straightened bushings will pass through the gap below the straightening baffle, while some that fail to straighten will slide along the curved surface of the straightening baffle into the gap and fall back to the top of the second top platform and the storage platform, ensuring that each bushing is straight and arranged in the discharge bin.

[0024] 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.
[0025] A detection and feeding mechanism for automotive outer tubes, such as Figure 1 - Figure 4 As shown, the device includes a top material box 1, with an inclined fabric hopper 11 on its inner wall. A first top platform 12 is slidably connected to the lowest point of the inclined fabric hopper 11. A second top platform 13 is slidably connected to the inner wall of the inclined fabric hopper 11 above the first top platform 12. A third top platform 14 is fixedly connected to the top of the top material box 1 above the second top platform 13. A storage platform 131 is fixedly connected to the inner wall of the inclined fabric hopper 11 at a position corresponding to the second top platform 13. The bottom of the second top platform 13 is fixedly connected to the bottom of the first top platform 12 via a connecting plate 16. A first cylinder 15 for lifting the connecting plate 16 is provided inside the top material box 1. The first top platform 12, the second top platform 13, and the third top platform 14 are arranged in a stepped manner, and the height intervals between them are consistent. The tops of the first top platform 12, the second top platform 13, the third top platform 14, and the storage platform 131 are all inclined, and the angle of inclination of the inclined surface is consistent with the angle of the bottom inclined surface of the inclined fabric hopper 11.
[0026] In this embodiment, the bushing to be measured is poured into the inclined fabric hopper 11. After entering the inclined fabric hopper 11, the bushing slides down the inclined surface to the top of the first top platform 12 at the lowest point. At this time, the first cylinder 15 drives the connecting plate 16 to connect the first top platform 12 and the second top platform 13 for reciprocating lifting and lowering to push the material. When the first top platform 12 is raised to the position of the storage platform 131, the bushing slides down the inclined surface of the first top platform 12 onto the storage platform 131. When the second top platform 13 descends, the storage material... The bushing on platform 131 will slide down the slope to the second top platform 13. As the second top platform 13 rises again to the position of the third top platform 14, the bushing above the second top platform 13 will slide down the slope to the top of the third top platform 14. By setting up the storage platform 131, the bushing is lifted in a multi-stage lifting process, reducing the height of the bushing in a single lifting, so as to avoid excessive height difference when falling during the lifting process, which would cause excessive force and damage to the bushing when it hits the ground.
[0027] like Figure 2 , Figure 3 As shown, preferably, a conveyor belt 3 is fixedly connected to the outside of the top material box 1 via a mounting plate 31. A discharge bin 32 is fixedly connected to one side of the conveyor belt 3. A notch 141 is provided on the side of the third top platform 14 near the discharge bin 32. A straightening baffle 33 is fixedly connected above the conveyor belt 3 at the position corresponding to the notch 141. A positioning platform 2 is provided on one side of the discharge bin 32 for positioning the bushing for testing. A discharge port 34 is provided in the discharge bin 32 at the position corresponding to the positioning platform 2.
[0028] In this embodiment, when the bushing slides down to the top of the third top platform 14, the bushing will slide along the inclined surface of the third top platform 14 to the top of the conveyor belt 3. The conveyor belt 3 will transport the bushing above to the discharge bin 32 for queuing. Since the diameter of the bushing is longer than the height of the bushing, the gap below the straightening baffle 33 is just enough to allow the straightened bushing to pass through. When the bushing that has tilted passes through the straightening baffle 33, some will be pushed down and straightened. The straightened bushing will pass through the gap below the straightening baffle 33, while some that fail to be straightened will slide along the arc surface of the straightening baffle 33 into the position of the notch 141 and fall back to the top of the second top platform 13 and the storage platform 131, so as to ensure that each bushing is straight and arranged in the discharge bin 32.
[0029] like Figure 4 As shown, preferably, a linear guide rail 21 is fixedly connected to the top of the positioning platform 2, a second cylinder 22 is slidably connected to the top of the linear guide rail 21, a support plate 23 is fixedly connected to the telescopic end of the second cylinder 22, and a plurality of claws 24 are fixedly connected to the support plate 23, with the claws 24 spaced at the same interval.
[0030] In this embodiment, the second cylinder 22 extends the claw 24 on the support plate 23 to grip the bushing at the discharge port 34 on the discharge bin 32. Then, the linear guide rail 21 drives the bushing inside the claw 24 to move laterally towards the positioning table 2. The distance of each lateral movement is consistent with the distance between the claws 24. After each movement, the second cylinder 22 controls the claw 24 on the support plate 23 to leave the bushing. The linear guide rail 21 controls the initial gripping position of the claw 24 on the support plate 23, and so on, to perform reciprocating gripping, so as to facilitate the positioning of each bushing to be tested, so as to facilitate the testing with the testing equipment.
[0031] In use, the inspection and feeding mechanism for automotive outer tubes of this utility model involves pouring the bushing to be measured into the inclined material hopper 11. After entering the inclined material hopper 11, the bushing slides down the inclined surface to the top of the first top platform 12 at its lowest point. At this time, the first cylinder 15 drives the connecting plate 16 to connect the first top platform 12 and the second top platform 13 for reciprocating lifting and lowering. When the first top platform 12 is raised to the position of the storage platform 131, the bushing slides down the inclined surface of the first top platform 12 onto the storage platform 131. When the second top platform 13 descends, the bushing on the storage platform 131 slides down the inclined plane onto the second top platform 13. As the second top platform 13 rises again to the position of the third top platform 14, the bushing above the second top platform 13 slides down the inclined plane onto the third top platform 14. When the bushing slides down onto the third top platform 14, it slides down the inclined plane onto the conveyor belt 3. The conveyor belt 3 transports the bushing to the discharge bin 32 for queuing. Because the diameter of the bushing is greater than its height... The gap below the straightening baffle 33 is just large enough to allow the straightened bushings to pass through. When a bushing that has tilted over passes through the straightening baffle 33, some will be pushed over and straightened. The straightened bushings will pass through the gap below the straightening baffle 33, while some that fail to straighten will slide along the curved surface of the straightening baffle 33 into the notch 141 and fall back above the second top platform 13 and the storage platform 131. This ensures that each bushing is in a straightened state in the discharge bin 32. The second cylinder 22 extends... The claws 24 on the support plate 23 grip the bushing at the discharge port 34 on the discharge bin 32. Then, the linear guide rail 21 drives the bushing inside the claws 24 to move laterally towards the positioning table 2. The distance of each lateral movement is consistent with the distance between the claws 24. After each movement, the second cylinder 22 controls the claws 24 on the support plate 23 to leave the bushing. The linear guide rail 21 controls the initial gripping position of the claws 24 on the support plate 23. This is repeated to facilitate the positioning of each bushing to be inspected.
