Description
Technical Field
[0001] This utility model relates to the field of automotive processing technology, and in particular to a rust removal device for machining axle shafts. Background Technology
[0002] The axle is a key component on a vehicle axle used to mount wheels, bear the weight of the vehicle, transmit power, and withstand various forces. Its performance is closely related to the vehicle's driving stability and safety. Rust removal is necessary during axle axle machining because rust not only impairs machining accuracy, leading to dimensional deviations and increased surface roughness, affecting the fit with other components, but also weakens the axle axle's mechanical properties, shortens its service life, and poses safety hazards. Furthermore, rust interferes with the cooling and lubrication functions of cutting fluid, accelerates tool wear, reduces machining efficiency and quality, and causes insufficient adhesion of subsequent surface treatment coatings, resulting in peeling and affecting appearance and protective performance. Therefore, rust removal equipment is used.
[0003] In existing technologies, some rust removal devices are often simply placed directly on the processing table to carry out rust removal operations. However, during the processing, due to the shape characteristics of the axle itself and the mechanical force generated by the rust removal operation, the material is prone to shaking and displacement. This instability seriously interferes with the accuracy of the rust removal process. Moreover, the grinding only targets the surface of the axle and does not grind and remove rust from the internal connecting holes, which will affect the overall use in the future. Utility Model Content
[0004] To overcome the above shortcomings, this utility model provides a rust removal device for axle machining, which aims to improve the situation in the prior art where materials are prone to shaking and displacement. This instability seriously interferes with the accuracy of the rust removal process, and the grinding only targets the surface of the axle without grinding and removing rust from the internal connecting holes, which will affect the overall use in the future.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] A rust removal device for machining axle shafts includes a worktable, a base fixedly connected inside the worktable, a motor fixedly connected to the inner wall of the bottom end of the base, a connecting shaft fixedly connected to the drive end of the motor, a turntable fixedly connected to the top of the connecting shaft, connecting rods rotatably connected to the left and right sides of the turntable, a connecting rod rotatably connected to the other end of the connecting rod, a clamping plate fixedly connected to the top of the connecting rod, a limit component provided inside the base, a protective component provided on the top of the worktable, a support frame fixedly connected to the outside of the worktable, a filter component provided inside the support frame, and a grinding component that can penetrate deep into the inner wall of the axle hole at the bottom of the support frame.
[0007] As a further description of the above technical solution:
[0008] The limiting component includes two limiting grooves, which are respectively opened on the left and right sides of the base, and square sliding grooves are opened on the top left and right sides of the worktable.
[0009] As a further description of the above technical solution:
[0010] The connecting rod is externally slidably connected to the inner wall of the limiting groove, the connecting rod is externally slidably connected to the inner wall of the square sliding groove, and a hydraulic cylinder is fixedly connected inside the support frame.
[0011] As a further description of the above technical solution:
[0012] The protective assembly includes a flexible protective cover, the top of which is fixedly connected to the drive end of a hydraulic cylinder. Multiple fixed posts are fixedly connected to the top of the flexible protective cover. Limit plates are fixedly connected to the top of the fixed posts. A connecting plate is slidably connected to the outside of the hydraulic cylinder. A spring is sleeved on the outside of the fixed posts.
[0013] As a further description of the above technical solution:
[0014] One end of the spring is fixedly connected to the bottom of the connecting plate, and the other end of the spring is fixedly connected to the top of the flexible protective cover;
[0015] As a further description of the above technical solution:
[0016] The grinding assembly includes a second motor, the top of which is fixedly connected to the inner wall of the top of the flexible protective cover, and a grinding head is fixedly connected to the drive end of the second motor.
[0017] As a further description of the above technical solution:
[0018] The filter assembly includes a fan, the bottom of which is fixedly connected to the top of the support frame, a connecting pipe is fixedly connected to the air inlet of the fan, a mounting base is fixedly connected to the bottom of the connecting pipe, and a filter plate is provided inside the mounting base.
[0019] As a further description of the above technical solution:
[0020] The support frame has a fixedly connected cargo box inside, and the bottom of the cargo box is detachably connected to a corrugated pipe. The other end of the corrugated pipe is fixedly connected to the inside of the flexible protective cover.
[0021] This utility model has the following beneficial effects:
[0022] 1. In this utility model, when the turntable rotates, the connecting rods fixedly connected to both sides of it make a circular motion. Under the precise restriction of the limiting groove, the connecting rod drives the connecting rod to slide in the square slide groove, ensuring that the clamping plate at the top of the connecting rod can move precisely in opposite directions or towards each other. When the two clamping plates gradually approach each other, the material with special anti-slip treatment on its surface is tightly attached to the surface of the axle shaft, generating strong friction, which firmly fixes the axle shaft in a suitable position, effectively avoiding the shaking and displacement of the axle shaft during processing, providing a stable foundation for subsequent grinding and rust removal operations, and greatly improving the precision and quality of rust removal processing.
[0023] 2. In this invention, after contacting the axle axle surface, the grinding head achieves a tight fit with the axle axle surface through the synergistic action of the connecting plate and spring. The grinding head penetrates deep into the inner wall of the connecting hole of the axle, effectively preventing debris from splashing during the grinding process and ensuring operator safety. Simultaneously, the fan, as the power core of the debris collection system, generates strong suction upon startup, causing debris within the flexible protective cover to be drawn into the storage box sequentially through the connecting pipe and corrugated pipe under the action of airflow. The flexible design of the connecting pipe and corrugated pipe adapts to positional changes caused by the movement of device components, ensuring a smooth collection process. The filter plate inside the mounting base precisely intercepts debris, preventing it from entering the fan and ensuring its normal operation. This not only optimizes the working environment and reduces damage to the equipment from debris but also extends the service life of the device and improves overall work efficiency.

[0031] 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.
[0032] Reference Figure 1 , Figure 2 and Figure 5 One embodiment of this utility model is a rust removal device for machining axle shafts, including a workbench 1, which is the foundation of the entire device. A base 2 is fixedly connected inside the workbench 1, and a motor 3 is fixedly connected to the inner wall of the bottom end of the base 2. During installation, the motor 3 is tightly fixed to the base 2 by bolts to ensure that the motor 3 will not shake during operation.
[0033] The drive end of motor 3 is fixedly connected to a connecting shaft 4. Motor 3 has a stable and powerful power output, which can provide continuous rotational power to the connecting shaft 4 according to the set speed and torque requirements. A turntable 5 is fixedly connected to the top of the connecting shaft 4. The connecting shaft 4 plays a key role in power transmission in the whole device, accurately transmitting the rotational power of motor 3 to the turntable 5. The turntable 5 can rotate smoothly and uniformly around the axis of the connecting shaft 4.
[0034] Connecting rods 6 are rotatably connected to the left and right sides of the turntable 5. When the turntable 5 rotates, the connecting rods 6 move in a circular motion with the turntable 5. The other end of the connecting rod 6 is rotatably connected to a connecting rod 7. A clamping plate 8 is fixedly connected to the top of the connecting rod 7. When the two clamping plates 8 move in opposite directions under the drive of the connecting rod 7, the distance between the two clamping plates 8 increases. At this time, the axle shaft can be easily placed on the worktable 1. When the two clamping plates 8 gradually approach each other, the two clamping plates 8 can tightly clamp the axle shaft and firmly fix the axle shaft in a suitable position, providing a stable foundation for subsequent rust removal operations.
[0035] The base 2 is equipped with a limiting component, which includes two limiting grooves 9. The two limiting grooves 9 are respectively opened on the left and right sides of the base 2. The external part of the connecting rod 6 is slidably connected to the inner wall of the limiting groove 9. The limiting groove 9 strictly limits the movement trajectory of the connecting rod 6, so that the connecting rod 6 can only move according to the preset curve, thereby ensuring that the clamping plate 8 can accurately move in opposite directions or towards each other, and realize the precise clamping and releasing operation of the axle shaft.
[0036] Square grooves 10 are provided on both the left and right sides of the top of the workbench 1. The square grooves 10 can ensure that the connecting rod 7 slides smoothly in them, while strictly restricting its direction of movement. The outer side of the connecting rod 7 is slidably connected to the inner wall of the square groove 10. The square groove 10 strictly restricts the direction of movement of the connecting rod 7, so that it can only move in a straight line in the horizontal direction.
[0037] Reference Figure 3 The workbench 1 is externally fixedly connected to a support frame 11, and a hydraulic cylinder 12 is internally fixedly connected to the support frame 11, providing a stable foundation for the installation of the hydraulic cylinder 12. A protective assembly is provided on the top of the workbench 1, including a flexible protective cover 13. The top of the flexible protective cover 13 is fixedly connected to the drive end of the hydraulic cylinder 12. The hydraulic cylinder 12 is the power source that drives the flexible protective cover 13 to move up and down, achieving precise lifting and lowering of the flexible protective cover 13.
[0038] The top of the flexible protective cover 13 is fixedly connected to multiple fixed posts 14. During the descent of the flexible protective cover 13 driven by the hydraulic cylinder 12, the fixed posts 14 serve as guides and limiters. The top of the fixed posts 14 is fixedly connected to a limit plate 15. A connecting plate 16 is slidably connected to the outside of the hydraulic cylinder 12. The connecting plate 16 serves as a connection and buffer in the protective assembly. A spring 17 is sleeved on the outside of the fixed posts 14. The flexible protective cover 13 can effectively prevent the flying of debris generated during the grinding process, and when in contact with the surface of the axle shaft, it can adapt to the shape changes of the axle shaft through the buffering effect of the spring 17 to achieve a tight fit.
[0039] One end of the spring 17 is fixedly connected to the bottom of the connecting plate 16. During the process of the hydraulic cylinder 12 driving the flexible protective cover 13 to descend, when the connecting plate 16 contacts the bottom of the limiting plate 15, the limiting plate 15 can prevent the connecting plate 16 from continuing to move downward. The other end of the spring 17 is fixedly connected to the top of the flexible protective cover 13. The spring 17 can absorb external force during compression and play a buffering role to avoid the flexible protective cover 13 causing excessive impact on the surface of the axle shaft.
[0040] Meanwhile, due to its own elastic restoring force, the spring 17 will generate an upward reaction force on the flexible protective cover 13, ensuring that the flexible protective cover 13 always maintains a tight fit with the surface of the axle, providing good protection and working conditions for the grinding and rust removal operation. The bottom of the support frame 11 is equipped with a grinding component that can penetrate deep into the inner wall of the axle hole. The grinding component includes a second motor 18, the top of which is fixedly connected to the inner wall of the top of the flexible protective cover 13. The drive end of the second motor 18 is fixedly connected to a grinding head 19. The second motor 18 is the power source that drives the grinding head 19 to perform rust removal. Driven by the second motor 18, the grinding head 19 rotates at high speed, entering the inner wall of the hole inside the axle, and grinding away the rust through friction, thus achieving the purpose of rust removal.
[0041] Reference Figure 4 The support frame 11 houses a filter assembly, including a fan 20. The bottom of the fan 20 is fixedly connected to the top of the support frame 11. The fan 20 has strong suction power, enabling it to quickly extract debris generated during grinding from inside the flexible protective cover 13. A connecting pipe 21 is fixedly connected to the air inlet of the fan 20. The connecting pipe 21 ensures that the fan 20 will not break or deform due to airflow impact during operation, and it can adapt to positional changes in different operating states. A mounting base 24 is fixedly connected to the bottom of the connecting pipe 21. A filter plate 25 is housed inside the mounting base 24. The internal space of the mounting base 24 precisely matches the filter plate 25, allowing the filter plate 25 to be tightly embedded within it.
[0042] The filter plate 25 effectively intercepts various debris generated during grinding while ensuring smooth airflow. A storage box 22 is fixedly connected inside the support frame 11, providing sufficient volume to store debris generated over a certain period. A corrugated pipe 23 is detachably connected to the bottom of the storage box 22, with its other end fixedly connected to the inside of the flexible protective cover 13. The corrugated pipe 23 adapts to positional changes caused by component movement during device operation, ensuring connection stability.
[0043] Working principle: First, place the material to be processed on the top of the workbench 1. Then, start the motor 3. Under the drive of the motor 3, the connecting shaft 4 drives the turntable 5 to rotate inside the base 2. As the turntable 5 rotates, it will drive the connecting rod 6 to rotate along the inner wall of the limiting groove 9, thereby enabling the connecting rod 6 to drive the connecting rod 7 to slide on the inner wall of the square slide groove 10. Under the restriction of the square slide groove 10, the clamping plate 8 can move. When the two clamping plates 8 move in opposite directions, they will not fix the material. When the two clamping plates 8 gradually approach each other, they can clamp and fix the material, thus fixing the material in a suitable position.
[0044] Then, the hydraulic cylinder 12 is activated. Driven by the hydraulic cylinder 12, the flexible protective cover 13 moves downward towards the material. The flexible protective cover 13 will first contact the surface of the material. As the hydraulic cylinder 12 moves downward, the connecting plate 16 will contact the bottom of the limiting plate 15 and continuously squeeze the spring 17. At this time, the spring 17 is compressed and absorbs the external force. Due to its own elasticity, it generates a reaction force on the flexible protective cover 13, making the flexible protective cover 13 contact the surface of the material more tightly, thereby preventing the debris generated by subsequent grinding from overflowing. At the same time, the grinding head 19 is inserted into the hole of the car axle under the action of the hydraulic cylinder 12.
[0045] Then, the second motor 18 is started, and the grinding head 19 operates under the drive of the second motor 18. When the grinding head 19 grinds the hole of the car axle, it will generate debris. As the fan 20 is started, the debris inside the flexible protective cover 13 is extracted through the connecting pipe 21 and the corrugated pipe 23 under the drive of the fan 20, so that the debris enters the interior of the cargo box 22. At the same time, the filter plate 25 inside the mounting base 24 can filter the debris, which can prevent the debris from entering the interior of the fan 20 and avoid affecting its normal use.
[0046] It is worth noting that the position of the grinding head 19 in the hole of the car axle can be adjusted by the hydraulic cylinder 12, thereby ensuring the thoroughness of the grinding, while the flexible protective cover 13 makes an adaptive contraction movement.
[0047] 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. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
