Description

Technical Field

[0001] This invention relates to the field of deburring equipment technology, specifically to a deburring device for processing shock absorber guides. Background Technology

[0002] Automotive shock absorbers are typically installed on the vehicle's suspension system to rapidly dampen vibrations from the body and frame, improving ride smoothness and comfort. The guide assembly's primary function in a shock absorber is to reduce friction between the piston rod and the guide bushing, thereby extending the lifespan of the piston rod and oil seal. The guide assembly consists of guide components, bushings, sealing rings, and wave springs. The sealing ring, wave spring, and bushings are sequentially installed within the guide components, while the piston rod slides within the bushing's inner diameter.

[0003] Guide elements are generally manufactured using powder metallurgy. Due to the mold-forming process, burrs are present at the mold joints. Furthermore, the multi-step structure, significant height differences, and uneven density distribution make burrs more likely to form during production. The presence of burrs can lead to assembly problems and scratches on parts due to residual burrs. Therefore, burr removal during production is a requirement for high-end shock absorber components. However, burrs after sintering are strong and difficult to remove. Removing burrs during the green blank stage will improve efficiency and reduce costs.

[0004] Currently, the most common method for deburring green blanks is using a spray medium. This medium allows for better contact with the inner surfaces and corners of the guide components, resulting in a more refined deburring effect. However, this method is slower for larger flat surfaces, often requiring a longer processing time and resulting in low deburring efficiency. Furthermore, the processed medium contains a significant amount of burr waste, which cannot be cleaned simultaneously with the deburring process. Post-processing recycling is typically employed, which presents considerable challenges. Summary of the Invention

[0005] The purpose of this invention is to provide a burr removal device for processing shock absorber guides, so as to improve the deburring effect and make the post-processing of the medium easier, thereby solving the problems mentioned in the background art.

The inclined guide groove is connected to a circulation pipe structure with airflow boosting function, and the outlet of the circulation pipe structure is located above the processing space.

[0007] Preferably, the partition plate is horizontally arranged in the middle of the processing box, with a deburring chamber above the partition plate and a recycling chamber below it. The drive motor is installed at the bottom of the partition plate, and the rotating disk is rotatably arranged on the upper surface of the partition plate.

[0008] Preferably, the rotating disk is a disc, and an inner core cylinder is provided in the middle of the rotating disk. The limiting cylinder is fixedly installed on the partition plate, and the rotating disk forms the bottom surface of the limiting cylinder.

[0009] Preferably, four support rods are symmetrically arranged around the limiting cylinder, and the mounting base is located at the top of the support rod. The mounting base is provided with a slot, and a positioning pin is movably mounted on the mounting base by a positioning spring.

[0010] Preferably, the arc-shaped grinding structure includes a hanging base inserted into a slot, and the hanging base is provided with a limiting groove. The positioning pin is connected to the limiting groove. A central rod is vertically provided at the bottom of the hanging base, and an elastic base plate is provided on the central rod. The front surface of the elastic base plate is covered with a grinding layer.

[0011] Preferably, a guide rod is fixedly installed on the hanging base, and an adjusting block is slidably installed on the guide rod. A control rope is fixedly connected to the adjusting block, and the adjusting block is fixed to the guide rod by a positioning component.

[0012] Preferably, the control rope is installed through the guide rod, and there are at least four control ropes. One end of the control rope is connected to the bottom of the adjusting block, and the other end is connected to the side of the elastic base plate. The positioning component is a positioning screw.

[0013] Preferably, the inlet of the recovery pipe is connected to the recovery gap, and the recovery pipe is vertically arranged. The air separation structure includes a vibrating bottom membrane disposed on the bottom surface of the recovery pipe, and the vibrating bottom membrane is driven by a vibrating motor. A weak air inlet pipe is connected to the middle of the recovery pipe, and the processing tank and the weak air inlet pipe are located at the same height.

[0014] Preferably, the inclined guide trough is located at the top of the recovery pipe, and the circulation pipe structure includes a recovery trough communicating with the inclined guide trough. A guide pipe is connected to the bottom of the recovery trough, a filter pipe is provided in the middle of the guide pipe, and a side pipe is fixedly connected to the guide pipe. The side pipe is connected to a forced air intake pipe.

[0015] Preferably, the recycling tank is vertically arranged, and the inclined guide channel is connected to the top of the recycling tank. The guide pipe is a bent pipe, and the outlet of the guide pipe is set towards the processing space. The filter pipe is set downward, and a filter screen is provided at the connection between the filter pipe and the guide pipe.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. The burr removal device of the present invention can simultaneously perform medium collision and grinding to complete the deburring of guide components. The deburring process of guide components takes place at the top of the rotating disk and inside the limiting cylinder. The components are placed in the processing space formed by the two and mixed with the deburring medium. Then, the rotating disk rotates, driving the components and the medium to move. The collision between the two can achieve the deburring effect and avoid dead corners. At the same time, an arc-shaped grinding structure is set around the periphery of the limiting cylinder. The arc-shaped grinding structure is attached to the inner wall of the limiting cylinder. When the components pass through, they can also be impacted and ground to remove burrs on the components. The arc-shaped grinding structure has a large contact area with the components. Combined with the medium with a small contact area, it can achieve an all-round deburring effect.

[0018] 2. In this invention, the arc-shaped grinding structure can be quickly assembled around the limiting cylinder and can be disassembled when it is necessary to maintain the grinding surface or adjust the grinding surface area. The arc-shaped grinding structure has an elastic base plate with a grinding layer installed on the hanger. The deburring work is completed through the contact between the parts and the grinding layer. The two sides of the elastic base plate can be rolled up to adjust the curvature of the grinding layer, so that the grinding layer can have grinding surfaces with different areas, which can be adjusted according to the different sizes of the parts.

[0019] 3. In addition to the comprehensive deburring using the medium and grinding layer on the rotating disk, this invention also includes a medium cleaning and circulation mechanism. A recovery notch is provided on the limiting cylinder, the size of which is smaller than the component. The medium and burr debris can enter the recovery pipe through the recovery notch and inlet groove. Separation is achieved using an air separation structure. In this structure, a weak airflow is generated towards the middle of the recovery pipe through a weak air inlet pipe. As the medium and debris pass through the airflow, the weak airflow blows the debris into the processing tank, from where it falls into the recovery chamber. The medium, being heavier, cannot be blown away by the weak airflow and can move to the top of the recovery pipe, falling into the inclined guide groove. The medium then enters the circulation pipe structure from the inclined guide groove, where it can be further cleaned before finally returning to the processing space. Deburring is completed simultaneously with circulation cleaning, making subsequent recycling more convenient. Attached Figure Description

[0031] The present invention will now be further described with reference to the accompanying drawings and specific embodiments. It should be noted that, without conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments. It should be understood that the described embodiments are merely some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0032] Please see Figures 1 to 10 This invention provides a technical solution: a burr removal device for processing shock absorber guides, comprising a processing box 1, a partition plate 2 disposed in the processing box 1, and the space inside the processing box 1 divided into a deburring chamber 3 and a recovery chamber 4 by the partition plate 2; a drive motor 5 fixedly mounted on the partition plate 2, and a rotating disk 6 driven by the drive motor 5 disposed on the partition plate 2; a limiting cylinder 7 disposed outside the rotating disk 6, and a processing space formed between the rotating disk 6 and the limiting cylinder 7; the processing space is filled with a deburring medium; and the limiting cylinder is surrounded on the partition plate 2. 7 is provided with a support rod 8, and a mounting base 9 is slidably installed on the support rod 8. The mounting base 9 is equipped with an arc-shaped grinding structure with curvature adjustment function. The limiting cylinder 7 is provided with a recycling notch 22, and a recycling pipe 23 with an inlet groove 24 is fixedly installed in the recycling notch 22. An air separation structure is provided in the recycling pipe 23, and a processing tank 28 is connected to one side of the recycling pipe 23 and an inclined guide groove 29 is connected to the other side. The inclined guide groove 29 is connected to a circulation pipe structure with airflow boosting function, and the outlet of the circulation pipe structure is located above the processing space.

[0033] The partition plate 2 is horizontally set in the middle of the processing box 1, with the deburring chamber 3 above the partition plate 2 and the recycling chamber 4 below. The drive motor 5 is installed at the bottom of the partition plate 2, and the rotating disk 6 is rotatably set on the upper surface of the partition plate 2.

[0034] The burr removal device of the present invention has a box structure, the main body of which is a processing box 1. The space inside the processing box 1 is divided into upper and lower sides by a partition plate 2. The deburring of the guide parts is carried out in the upper deburring chamber 3, and the processed burr debris can enter the lower recycling chamber 4 for collection.

[0035] The rotating disk 6 is a disc, and an inner core cylinder is provided in the middle of the rotating disk 6. The limiting cylinder 7 is fixedly installed on the partition plate 2, and the rotating disk 6 forms the bottom surface of the limiting cylinder 7.

[0036] The deburring process of the guide components is carried out on the top of the rotating disk 6 and inside the limiting cylinder 7. The components are placed in the processing space formed by the two and mixed with the deburring medium. Then, the rotating disk 6 rotates, which drives the components and the medium to move. The collision between the two can achieve the deburring effect and it is not easy to have dead corners.

[0037] Four support rods 8 are symmetrically arranged around the limiting cylinder 7, and the mounting base 9 is located at the top of the support rod 8. The mounting base 9 is provided with a slot 10, and a positioning pin 12 is movably installed on the mounting base 9 through a positioning spring 11.

[0038] Meanwhile, the present invention features an arc-shaped grinding structure around the periphery of the limiting cylinder 7. This arc-shaped grinding structure is installed via a mounting base 9. When needed, it can be inserted into the limiting cylinder 7 from the mounting base 9. By sliding the mounting base 9 on the support rod 8, the arc-shaped grinding structure can be made to rest against the inner wall of the limiting cylinder 7. When the parts pass by, they can also be impacted and ground to remove burrs from the parts. The arc-shaped grinding structure has a large contact area with the parts, and when combined with a medium with a small contact area, it can achieve an all-round deburring effect.

[0039] The arc-shaped grinding structure includes a hanging base 13 inserted into the slot 10, and a limiting groove 14 is provided on the hanging base 13. The positioning pin 12 is connected in the limiting groove 14. A central rod 15 is vertically provided at the bottom of the hanging base 13, and an elastic base plate 16 is provided on the central rod 15. The front surface of the elastic base plate 16 is covered with a grinding layer 17.

[0040] When loading the arc-shaped grinding structure, connect its hanger 13 to the mounting base 9 and insert it into the slot 10. The hanger 13 can be quickly installed by connecting the positioning pin 12 to the limiting groove 14. It can be easily disassembled when it is necessary to maintain the grinding surface or adjust the grinding surface area.

[0041] A guide rod 18 is fixedly installed on the hanging base 13, and an adjusting block 19 is slidably installed on the guide rod 18. A control rope 20 is fixedly connected to the adjusting block 19, and the adjusting block 19 is fixed to the guide rod 18 by a positioning member 21.

[0042] An elastic base plate 16 with a polishing layer 17 is installed on the hanger 13. The deburring work is completed by the contact between the parts and the polishing layer 17. The two sides of the elastic base plate 16 can be rolled up to adjust the curvature of the polishing layer 17, so that the polishing layer 17 can have polishing surfaces with different areas, which can be adjusted according to the size of the parts.

[0043] A buffer layer is provided between the grinding layer 17 and the elastic base plate 16 to prevent the workpiece from being damaged by impacting the grinding layer 17 when it rotates.

[0044] The control rope 20 is installed through the guide rod 18, and there are at least four control ropes 20. One end of the control rope 20 is connected to the bottom of the adjusting block 19, and the other end is connected to the side of the elastic base plate 16. The positioning component 21 adopts a positioning screw.

[0045] The curvature of the polishing layer 17 is adjusted by adjusting block 19, which can move up and down on guide rod 18 to adjust the tension of control rope 20. When control rope 20 contracts, it can pull the two sides of elastic base plate 16, thereby causing polishing layer 17 to roll up. Conversely, it can cause polishing layer 17 to stretch out, achieving the effect of arbitrary adjustment.

[0046] The inlet 24 of the recovery pipe 23 is connected to the recovery notch 22, and the recovery pipe 23 is set vertically. The air separation structure includes a vibrating bottom membrane 26 set on the bottom surface of the recovery pipe 23, and the vibrating bottom membrane 26 is driven by a vibrating motor 25. A weak air inlet pipe 27 is connected to the middle of the recovery pipe 23, and the processing tank 28 and the weak air inlet pipe 27 are at the same height.

[0047] In addition to the omnidirectional deburring using the medium and polishing layer 17 on the rotating disk 6, this invention also includes a medium cleaning and circulation mechanism. The limiting cylinder 7 is provided with a recovery notch 22, the size of which is smaller than that of the component. The medium and burr debris can enter the recovery pipe 23 through the recovery notch and the inlet trough 24 and fall onto the vibrating bottom membrane 26 at the bottom of the recovery pipe 23. The vibration generated by the vibration motor 25 driving the vibrating bottom membrane 26 can lift the medium and debris together, thereby using the air separation structure to complete the separation. In the air separation structure, a weak airflow is generated to the middle of the recovery pipe 23 through the weak air inlet pipe 27. When the medium and debris pass through the airflow, the weak airflow can blow the debris into the processing trough 28 and then into the recovery chamber 4. The medium is heavier and cannot be blown away by the weak airflow. Under the elastic force generated by the vibrating bottom membrane 26, the medium can overcome the gravity and the wind force of the weak airflow and be pushed up to the top of the recovery pipe 23 and fall into the inclined guide trough 29.

[0048] The inclined guide trough 29 is located at the top of the recovery pipe 23, and the circulation pipe structure includes a recovery trough 30 that communicates with the inclined guide trough 29. The bottom of the recovery trough 30 is connected to a guide pipe 31, a filter pipe 32 is provided in the middle of the guide pipe 31, and a side pipe 33 is fixedly connected to the guide pipe 31. The side pipe 33 is connected to a forced air intake pipe 34.

[0049] The medium enters the circulation pipeline structure from the inclined guide trough 29, where it can be further cleaned before finally returning to the processing space, thus serving as a deburring agent.

[0050] The recycling tank 30 is set vertically, and the inclined guide trough 29 is connected to the top of the recycling tank 30. The guide pipe 31 is a bent pipe, and the outlet of the guide pipe 31 is set towards the processing space. The filter pipe 32 is set downward, and a filter screen is set at the connection between the filter pipe 32 and the guide pipe 31.

[0051] The medium falls from the inclined guide trough 29 into the recovery tank 30, and then enters the guide pipe 31. The strong air intake pipe 34 on the side of the guide pipe 31 generates an airflow that can propel the medium to move, and the medium is sent back to the processing space through the guide pipe 31, achieving the effect of recycling. During the movement of the medium, the burrs and debris adhering to it can be detached and fall from the filter pipe 32 into the recovery chamber 4.

[0052] In use, the present invention is as follows: First, the burr removal device of the present invention has a box structure, the main body of which is a processing box 1. The space inside the processing box 1 is divided into upper and lower sides by a partition plate 2. The deburring of the guide components is carried out in the upper deburring chamber 3, and the processed burr debris can enter the lower recycling chamber 4 for collection. The deburring process of the guide components takes place at the top of the rotating disk 6 and inside the limiting cylinder 7. The components are placed in the processing space formed by the two and mixed with the deburring medium. Then, the rotating disk 6 rotates, driving the components and the medium to move. The collision between the two can achieve the deburring effect and avoid dead corners. At the same time, the present invention has an arc-shaped grinding structure around the periphery of the limiting cylinder 7. This arc-shaped grinding structure is... The arc-shaped grinding structure is installed via mounting base 9. When needed, it can be inserted into the limiting cylinder 7 from the position of mounting base 9. By sliding mounting base 9 on support rod 8, the arc-shaped grinding structure can be made to rest against the inner wall of the limiting cylinder 7. When parts pass by, they can also be impacted and ground to remove burrs. The arc-shaped grinding structure has a large contact area with the parts, and when combined with a medium with a small contact area, it can achieve an all-round deburring effect. When loading the arc-shaped grinding structure, its hanger 13 is connected to mounting base 9 and inserted into slot 10. It is connected to the limiting groove 14 through positioning pin 12, which can quickly complete the installation of hanger 13. It can be easily disassembled when it is necessary to maintain the grinding surface or adjust the grinding surface area. The hanger 13 is equipped with a grinding mechanism. The installation of the elastic base plate 16 of the grinding layer 17 completes the deburring work through the contact between the component and the grinding layer 17. The two sides of the elastic base plate 16 can be rolled up, thereby adjusting the curvature of the grinding layer 17, allowing the grinding layer 17 to have grinding surfaces of different areas. This can be adjusted according to the size of the component. The curvature of the grinding layer 17 is adjusted by the adjusting block 19, which can move up and down on the guide rod 18, thereby adjusting the tension of the control rope 20. When the control rope 20 contracts, it pulls the two sides of the elastic base plate 16, causing the grinding layer 17 to roll up; conversely, it allows the grinding layer 17 to unfold, achieving a freely adjustable effect. This invention, when using the medium on the rotating disk 6 and the grinding layer 17 for all-around deburring, also includes... The system includes a media cleaning and circulation mechanism. A recovery notch 22 is provided on the limiting cylinder 7. The size of the recovery notch 22 is smaller than that of the components. Media and burr debris can enter the recovery pipe 23 through the recovery notch and inlet 24, falling onto the vibrating diaphragm 26 at the bottom of the recovery pipe 23. The vibration diaphragm 26 is driven by a vibration motor 25, and the resulting vibration lifts the media along with the debris, thus achieving separation using an air separation structure. In the air separation structure, a weak airflow is generated towards the middle of the recovery pipe 23 through a weak air inlet pipe 27. When the media and debris pass through the airflow, the weak airflow blows the debris into the processing tank 28, from where it falls into the recovery chamber 4. The media, being heavier, cannot be blown away by the weak airflow and can move to the top of the recovery pipe 23, falling into the inclined guide trough 29.The medium enters the circulation pipeline structure from the inclined guide trough 29, where it can be further cleaned before finally returning to the processing space, serving as a deburring agent. The medium falls from the inclined guide trough 29 into the recovery tank 30, and then into the guide pipe 31. The strong air intake pipe 34 on the side of the guide pipe 31 generates an airflow that propels the medium back to the processing space, achieving a recycling effect. During the medium's movement, any burrs and debris adhering to it can fall off and fall from the filter pipe 32 into the recovery chamber 4.

[0053] The above embodiments are merely preferred embodiments of the present invention and should not be construed as limiting the scope of protection of the present invention. Any modifications made by those skilled in the art based on the above concepts without creative effort shall fall within the scope of protection of the present invention.
