Description

Technical Field

[0001] This utility model relates to the field of automotive parts processing equipment technology, and in particular to a rust removal device for automotive axle processing. Background Technology

[0002] As the core load-bearing component of the chassis system, the axle is usually made of metal materials through casting or forging processes. During the production, processing, circulation, or long-term storage, its surface is very prone to rust due to oxidation. In order to ensure the adhesion of subsequent painting, assembly accuracy, and extend the service life of parts, the axle surface must be thoroughly derusted before finishing.

[0003] However, existing axle rust removal operations mostly use simple V-shaped brackets or static clamps for support when fixing the axle. Due to the large weight of the axle itself and its irregular long shaft structure, this traditional fixing method can only keep the axle stationary. During the rust removal process, whether using sandblasting or mechanical grinding, the operating tools cannot reach the bottom and back of the axle, resulting in obvious blind spots in the processing. To achieve all-round rust removal, workers often need to manually stop the work and rotate the axle frequently. This not only greatly increases the labor intensity and safety hazards, but also leads to discontinuous rust removal operations, making it difficult to ensure the uniformity of rust removal and production efficiency. In addition, if there is no convenient collection and cleaning mechanism for the large amount of rust slag generated during the rust removal process, it will also seriously affect the cleanliness of the processing environment.

[0004] Therefore, this utility model proposes a rust removal device for automobile axle processing to overcome the shortcomings of the prior art. Utility Model Content

[0005] In the existing technology, the rust removal process of automobile axles usually adopts a static support method, which cannot achieve uniform circumferential rotation of the axle, resulting in dead corners and low processing efficiency. In addition, the existing waste collection structure is cumbersome to disassemble and assemble, and inconvenient to clean and maintain. The present invention aims to provide a rust removal device for automobile axle processing with an improved structure that can automatically center, clamp and rotate the axle, and whose collection device is easy to disassemble and clean.

[0006] This utility model provides a rust removal device for automobile axle processing, including: a workbench, a connecting plate fixedly connected to the top of the workbench, a fixing frame fixedly installed on the top of the connecting plate, a positioning and clamping mechanism installed on the fixing frame, and a material collection box disposed at the bottom of the workbench.

[0007] The positioning and clamping mechanism adopts a structural design combining rotary drive and linkage opening and closing. Specifically, it includes a drive assembly fixedly installed on the outer wall of the fixed frame. The output end of the drive assembly passes through the fixed frame and is fixedly connected to a rotating plate. A connecting block is fixedly connected to the side of the rotating plate away from the drive assembly, and a fixed block is fixedly clamped between the connecting blocks. A connecting rod slides axially through the middle of the fixed block. One end of the connecting rod extends to the outside of the fixed block and is fixedly connected to an operating block. The other end of the connecting rod is fixedly connected to a movable rod. The positioning and clamping mechanism also includes a fixing assembly with a movable rod. The two ends of the movable rod are rotatably connected to one end of the movable rod, and the other end of the movable rod is slidably connected to clamping block one and clamping block two, respectively.

[0008] Furthermore, the collection box is suspended from the bottom of the workbench via a snap-fit ​​mechanism. The workbench, the fixed frame, and the positioning and clamping mechanism form a stable support system through hierarchical assembly. By pulling the connecting rod, the clamping block one and the clamping block two can move in opposite directions to achieve clamping. The drive assembly can drive the clamped axle to rotate as a whole.

[0009] Preferably, in order to realize the automatic reset and clamping function of the clamping mechanism, a reset spring is sleeved on the outer wall of the connecting rod, and the two ends of the reset spring abut against the fixed block and the operating block respectively; the first clamping block and the second clamping block are arranged opposite to each other, and under the action of the elastic restoring force provided by the reset spring, the first clamping block and the second clamping block tend to move closer to each other, thereby providing a continuous clamping force.

[0010] Preferably, to improve the ease of assembly and disassembly of the material collection device, a connecting groove is provided at the edge of the feed inlet on the top of the material collection box; the locking mechanism includes a fixing rod inserted into the connecting groove, a limiting rod being vertically fixedly connected to one end of the fixing rod extending into the feed inlet, and a lever being fixedly connected to one end of the fixing rod located outside the material collection box; by rotating the lever to drive the limiting rod to rotate, the material collection box and the worktable can be quickly locked or separated.

[0011] Preferably, in order to prevent the snap-fit ​​structure from loosening and to enhance stability, the connecting groove is constructed as an irregularly shaped through hole through which the limiting rod passes and is rotated and locked, and the limiting rod abuts against the inner wall of the feed inlet; at the same time, a fixing ring is fixedly sleeved on the outer circumference of the fixing rod, the fixing ring is located between the connecting groove and the lever, and the end face of the fixing ring abuts against the outer wall of the collection box.

[0012] Preferably, in order to ensure the stability and controllability of the drive, the drive assembly is selected as a rotary motor or rotary cylinder, and the drive assembly is used to drive the rotating plate, the fixed assembly and the clamped axle to rotate synchronously in the circumference.

[0013] Preferably, in order to facilitate the diversion and collection of waste materials, the bottom of the workbench is provided with a funnel-shaped discharge port, and the inlet of the collection box is connected to the funnel-shaped discharge port, so that the waste generated by rust removal can fall into the collection box.

[0014] Preferably, in order to adapt to the processing requirements of long-wheelbase axles and ensure support balance, the number of the fixing frames is set to two, and they are symmetrically distributed at both ends of the connecting plate. Each fixing frame is provided with the positioning and clamping mechanism to realize synchronous clamping and driving of both ends of the axle.

[0015] Preferably, in order to improve the smoothness of the mechanism's movement, the fixing component further includes guide brackets fixedly connected to both sides of the fixing block, the moving rod slidably passing through the guide brackets, and the moving rod and the movable rod being rotatably connected by a pin.

[0016] This utility model has the following beneficial effects:

[0017] 1. This utility model, by setting up a positioning and clamping mechanism, uses a connecting rod to drive the movable rod and the moving rod to control the opening and closing of the two clamping blocks, and cooperates with the return spring to achieve automatic clamping. At the same time, the drive component drives the entire clamping mechanism and the axle to rotate. This solves the problem in the prior art of lacking a stable clamping device that can adapt to different specifications of axles and the difficulty in achieving uniform circumferential rotation of the axle, which leads to dead corners in rust removal. It achieves the technical effect of being able to quickly adapt to axles of various specifications for centering and clamping, and drive the axle to rotate stably in the circumferential direction, ensuring that the rust removal operation is comprehensive and without dead corners, and significantly improving the processing quality and efficiency.

[0018] 2. This utility model, by setting up a snap-fit ​​mechanism, uses a fixed rod inserted into the connecting groove and then a twisting lever to drive the limiting rod at the end to rotate internally and snap into the inner wall, thus realizing the connection between the collection box and the workbench. This solves the problems of cumbersome disassembly and assembly and inconvenient cleaning and maintenance of rust removal waste collection devices in the prior art. It achieves the technical effect of quickly completing the disassembly and installation of the collection box without the aid of auxiliary tools, making waste cleaning work simpler and faster, and improving the convenience of equipment maintenance.

[0019] 3. This utility model solves the problem of long axles easily rotating and swaying due to cantilever bending moment caused by gravity when clamped at one end by symmetrically setting two fixed frames and positioning clamping mechanisms at both ends of the worktable. It achieves synchronous and stable support for both ends of the axle, ensuring that the axle remains horizontal and stable during rotation processing, and further guaranteeing the technical effect of rust removal accuracy.

[0030] Example:

[0031] Reference Figures 1 to 4 This utility model provides a rust removal device for automobile axle processing, which aims to solve the structural defects in the prior art where the axle cannot achieve uniform circumferential rotation during rust removal, resulting in dead corners for rust removal, and the cumbersome disassembly and assembly of the rust removal waste collection device, leading to inconvenient cleaning.

[0032] like Figure 1 and Figure 2As shown, a rust removal device for automobile axle processing includes a workbench 1 and a connecting plate 5 fixedly connected to the top of the workbench 1 by bolts. The connecting plate 5 serves as the main bearing plane, and two fixed frames 4 are symmetrically fixed at both ends of its top. The fixed frames 4 provide height support so that the axle can be suspended for processing. A positioning clamping mechanism 2 is installed on the fixed frame 4. The positioning clamping mechanism 2 functions to perform bidirectional centering clamping of axles of different specifications and can drive the clamped axle to rotate 360 ​​degrees in a circumferential direction, thereby cooperating with external rust removal tools to complete rust removal without dead angles. At the bottom of the workbench 1, a collection box 31 for collecting rust waste is provided. The collection box 31 can be quickly and easily detached and suspended by a snap-fit ​​mechanism 3.

[0033] like Figure 1 and Figure 3 As shown, the core execution component, the positioning and clamping mechanism 2 includes a drive assembly 21 fixedly installed on the outer wall of the fixed frame 4. The drive assembly 21 is preferably a low-speed, high-torque rotary cylinder. Its output shaft passes horizontally through the fixed frame 4 and is fixedly connected to the rotating plate 22 located on the inner side. The operation of the drive assembly 21 can drive the rotating plate 22 and all subsequent clamping components installed on the rotating plate 22 to rotate synchronously. A pair of connecting blocks 23 are welded or bolted to the side of the rotating plate 22 away from the drive assembly 21. A fixing block 24 is fixedly clamped between the two connecting blocks 23. The fixing block 24 serves as a guide base for the clamping action.

[0034] To enable the opening and closing action of the clamping claw, a through hole is opened in the middle of the fixed block 24 along the axial direction. A connecting rod 25 is slidably inserted through the through hole. One end of the connecting rod 25 extends to the outside of the fixed block 24 and is fixedly connected to an operating block 26. The operating block 26 is convenient for the operator to hold and pull. The other end of the connecting rod 25 is fixedly connected to a horizontally arranged movable rod 27. At the same time, a return spring is sleeved on the outer wall of the connecting rod 25. The two ends of the return spring abut against the end face of the fixed block 24 and the inner side of the operating block 26, respectively. The elastic force of the return spring always gives the connecting rod 25 an inward return tendency, thereby providing a continuous clamping force.

[0035] Furthermore, the positioning and clamping mechanism 2 also includes a fixed assembly 28 as the transmission execution end. The fixed assembly 28 is composed of a symmetrically arranged linkage mechanism, specifically including two moving rods 281. The two ends of the movable rod 27 are respectively rotatably connected to one end of the two moving rods 281 through pins, so that the other end of the moving rod 281 can perform opening and closing movements. The ends of the two moving rods 281 are respectively fixedly connected to clamping block one 282 and clamping block two 283. The inner surfaces of clamping block one 282 and clamping block two 283 are provided with anti-slip rubber pads for direct contact and engagement with the axle surface.

[0036] When the axle needs to be clamped, pull the operating block 26 outward to overcome the resistance of the return spring and drive the connecting rod 25 to move outward. The connecting rod 25 drives the movable rod 27 to move, and then, through the linkage transmission principle, it opens the two movable rods 281, so that the clamping block 1 282 and the clamping block 283 separate to both sides, leaving space for the axle to be placed. After the axle is placed, release the operating block 26, and the mechanism resets under the action of the return spring. The clamping block 1 282 and the clamping block 283 retract inward and clamp the axle tightly. Then, start the drive assembly 21 to drive the axle to rotate.

[0037] Reference Figure 4 The material collection box 31 is located directly below the workbench 1 and is used to collect the rust and dust that fall during the rust removal process above. The bottom of the workbench 1 is designed as a funnel-shaped structure. The bottom opening of the funnel-shaped structure is connected to the feed inlet 32 ​​at the top of the material collection box 31. In order to facilitate quick locking, a connecting groove 33 is provided on the side wall at the connection between the feed inlet 32 ​​and the funnel-shaped structure of the workbench 1. The connecting groove 33 is constructed as an irregular hole that allows a rod of a specific shape to be inserted and rotated to lock, such as a keyhole or a round hole with a notch.

[0038] The snap-fit ​​mechanism 3 is mainly composed of a plug-in component, specifically including a rigid fixing rod 34. The fixing rod 34 is a key force-bearing component connecting the collection box 31 and the worktable 1. At one end of the fixing rod 34 that can extend into the connecting groove 33, a short limiting rod 35 is vertically welded or integrally formed. The limiting rod 35 and the fixing rod 34 are distributed in a T-shape. When the fixing rod 34 is inserted into the connecting groove 33, the limiting rod 35 can pass through the notch of the connecting groove 33 and enter the internal space of the funnel structure. Then, by rotating the fixing rod 34, the limiting rod 35 will rotate to an angle outside the notch of the connecting groove 33, thereby abutting against the feed inlet 32 ​​or the inner wall of the funnel structure of the worktable 1, forming an axial limiting lock to prevent the collection box 31 from falling off under the action of gravity.

[0039] To facilitate manual application of rotational torque by the operator, a lever 37 is fixedly connected to one end of the fixed rod 34 located outside the collection box 31. The lever 37 is set perpendicular to the axis of the fixed rod 34, providing a lever arm for easy manual twisting. At the same time, to prevent excessive axial movement or accidental slippage of the fixed rod 34 in the locked state, a fixing ring 36 is fixedly fitted on the outer circumference of the fixed rod 34. The fixing ring 36 is positioned between the lever 37 and the outer wall of the connecting groove 33, and the end face of the fixing ring 36 is in close contact with the outer edge of the connecting groove 33, serving as a positioning and anti-reverse function as well as reinforcement and support.

[0040] This structural design, which uses a rotating lever 37 to drive the limiting lever 35 to rotate and lock in place, allows the collection box 31 to be installed without the need for tools such as screwdrivers or wrenches. It can be fixed simply by aligning it with the connecting slot 33, inserting it, and twisting it. When disassembling, the waste material can be removed and dumped by twisting it in the opposite direction, which greatly improves the efficiency of cleaning and maintenance.

[0041] As a preferred embodiment, in order to ensure that the driving force can be stably transmitted to the positioning and clamping mechanism 2 and realize the circumferential uniform rotation of the axle, the selected drive component 21 is preferably a servo motor with a reducer. The motor has a controllable speed and a large output torque. The drive component 21 is rigidly connected to the central shaft of the rotating plate 22 through a coupling connection, thereby ensuring that the entire clamping mechanism and the heavy axle can still be smoothly driven to rotate under heavy load, avoiding jamming or step loss.

[0042] As another preferred embodiment, in order to improve the smoothness and accuracy of the movement of the clamping block and prevent the moving rod 281 from deflecting when subjected to force, the part of the moving rod 281 in the fixed assembly 28 that passes through the fixed block 24 is equipped with a precision-machined guide hole or linear bearing, and the connection between the movable rod 27 and the moving rod 281 adopts a structure of rotating pin and oil-impregnated bushing to reduce frictional resistance, making the linkage mechanism transmission smoother and the operation feel better.

[0043] As another preferred embodiment, in order to enhance the grip on the axle surface and protect the axle from being pinched, a layer of high-strength industrial rubber pad is vulcanized and bonded to the inner clamping surfaces of clamping block 282 and clamping block 283. This design provides sufficient static friction to prevent the axle from slipping, while also providing a certain buffering and protection for the axle surface.

[0044] As another preferred embodiment, in order to adapt to the long structural characteristics of the axle and ensure the balance during processing, the number of fixing brackets 4 is set to two, and they are distributed in a mirror symmetrical manner at both ends of the top of the connecting plate 5. Each fixing bracket 4 is independently equipped with a complete set of positioning and clamping mechanisms 2. The two sets of positioning and clamping mechanisms 2 clamp the two ends of the axle synchronously on the same axis. This double-end clamping layout can effectively eliminate the gravitational bending moment at the cantilever end of the axle, ensure that the axle remains horizontal during the rotation and rust removal process, and avoid affecting the rust removal quality due to shaking.

[0045] The working principle is as follows:

[0046] When rust removal is required for automobile axles of different specifications, the operator first pulls the operating block 26 in the positioning clamping mechanism 2 outward. The operating block 26 drives the connecting rod 25 to overcome the resistance of the return spring and move outward to the fixed block 24. The connecting rod 25 further pulls the movable rod 27 fixedly connected to it to move backward.

[0047] As the movable rod 27 moves, the two movable rods 281 rotatably connected to its two ends are subjected to force and linkage. The movable rods 281 rotate around their fulcrum or slide along the guide trajectory, causing the clamping blocks 282 and 283 at their ends to open to both sides, thereby expanding the distance between them and forming an open space sufficient to accommodate the end of the axle.

[0048] At this point, the end of the axle to be processed is placed between clamping block 282 and clamping block 283. Then, the tension on the operating block 26 is released. Under the action of the elastic restoring force accumulated by the return spring, the connecting rod 25 and the movable rod 27 automatically retract and reset, driving the moving rod 281 to move in the opposite direction, so that clamping block 282 and clamping block 283 retract inward and tightly clamp the outer circumference of the axle, thus completing the centering and fixing of the axle.

[0049] After fixing, start the drive component 21 on the fixing frame 4. The drive component 21 drives the rotating plate 22 to rotate. Since the rotating plate 22 is connected to the entire clamping component through the connecting block 23 and the fixing block 24, and the clamping component has firmly clamped the axle, the axle will rotate circumferentially at a uniform speed. At this time, the external rust removal brush head or grinding tool can be used to contact and process the surface of the rotating axle to achieve all-round rust removal without dead angles.

[0050] During the rust removal process, rust debris will fall into the funnel structure below the workbench 1 and be collected into the collection box 31 through the feed inlet 32. When the collection box 31 is full and needs to be cleaned, the operator only needs to hold the lever 37 on the outside of the locking mechanism 3 and twist it in the opposite direction. The lever 37 drives the fixed rod 34 to rotate, so that the limiting rod 35 at the end of the fixed rod 34 rotates inside the connecting groove 33 to the position aligned with the notch, releasing the limiting lock on the inner wall of the funnel. Then, the fixed rod 34 is pulled out, and the collection box 31 can be separated from the workbench 1 for easy dumping of waste. After cleaning, the fixed rod 34 is inserted again and the lever 37 is twisted in the forward direction. The limiting rod 35 rotates and locks the inner wall, which can quickly complete the installation and reset of the collection box 31.
