Description

Technical Field

[0001] This invention belongs to the field of disassembly tool technology, specifically relating to a special disassembly tool for abrasive rollers in automotive clutch steel sheet grinding equipment and its usage method. Background Technology

[0002] The statements in this section are merely background information related to the present invention and do not necessarily constitute prior art.

[0003] In the production process of automotive clutch steel sheets, sanding roller polishing is a crucial step to ensure surface flatness and friction performance. As a core consumable, sanding rollers need to be replaced during regular maintenance. However, the industry currently faces the dual dilemma of low maintenance efficiency and high operational risks. Traditional methods rely on general-purpose tools such as adjustable wrenches and pipe wrenches, which are difficult to effectively match the non-circular anti-rotation shaft head unique to the sanding roller's rotating shaft. When disassembling the locking nut, slippage frequently occurs, with the shaft rotating with the nut, making circumferential locking impossible. This forces operators to use inefficient methods such as multiple people working together and temporary jamming, which is not only time-consuming and labor-intensive but also easily causes irreversible damage to the shaft head edges and nut grooves, shortening the core lifespan of the equipment. In addition, the equipment has a compact structure, with one end of the sanding roller shaft often deeply embedded inside the back plate frame, resulting in extremely limited space. Conventional tools are simply unable to penetrate or rotate effectively due to size limitations. Summary of the Invention

[0004] To address the aforementioned problems, this invention provides a special disassembly tool and method for grinding rollers in automotive clutch steel sheet grinding equipment, which solves the problems of not being able to lock circumferentially when disassembling and installing the rotating shaft of the grinding roller, and the inability of commonly used tools to achieve effective rotation in narrow spaces.

[0005] To achieve the above objectives, the present invention is implemented through the following technical solution: In a first aspect, the present invention provides a special disassembly tool for a grinding roller in an automotive clutch steel sheet grinding equipment, comprising: a first fixing member mounted on the rotating shaft of the grinding roller, a first disassembly member mounted on a first fixing nut on the rotating shaft of the grinding roller, a second fixing member mounted on the back plate of the grinding equipment, and a second disassembly member sleeved on a second fixing nut on the rotating shaft of the grinding roller; both the first fixing member and the second fixing member are provided with contour holes, the contour holes cooperating with the rotating shaft of the grinding roller, the first fixing member manually restricts the rotation of the rotating shaft of the grinding roller, and the second fixing member restricts the rotation of the rotating shaft of the grinding roller by fixing it to the back plate and cooperating with the contour holes; both the first disassembly member and the second disassembly member are provided with disassembly teeth, and the first fixing nut and the second fixing nut can be disassembled by rotating the disassembly teeth.

[0006] As a further implementation, the first disassembly component includes a first drive cylinder, a handle disposed at one end of the first drive cylinder, and the disassembly teeth disposed at the other end of the first drive cylinder.

[0007] As a further implementation, the first fixing member includes a first fixing cylinder, and the end of the first fixing cylinder is provided with the contour hole.

[0008] As a further implementation, the second disassembly component includes a second drive cylinder, a transition cylinder disposed at the end of the second drive cylinder, a Z-shaped handle disposed at the end of the transition cylinder, and the disassembly teeth disposed at the other end of the second drive cylinder.

[0009] As a further implementation, the second fastener includes a fixing plate and a mounting plate. One end of the fixing plate is provided with the contour hole, and the other end is fixedly connected to the mounting plate. The shape of the mounting plate is adapted to the shape of the back plate of the grinding equipment, and both ends of the mounting plate are provided with mounting holes. Fasteners are provided in the mounting holes, and the mounting plate is fixedly connected to the back plate of the grinding equipment through the fasteners.

[0010] As a further implementation, the sanding roller is fixedly connected to the middle of the sanding roller rotating shaft by a second fixing nut, and a sliding seat is provided at one end of the sanding roller rotating shaft. The sliding seat is disposed in the mounting frame of the back plate of the grinding equipment, and the sanding roller rotating shaft is mounted on the sliding seat by a first fixing nut.

[0011] As a further implementation, the first fixing member, the first disassembly member, the second fixing member, the second disassembly member, and the disassembly teeth are all formed by stamping or cutting steel and welding.

[0012] As a further implementation, the number of slots on the first fixing nut is the same as the number of disassembly teeth on the first disassembly component, and their positions correspond; the number of slots on the second fixing nut is the same as the number of disassembly teeth on the second disassembly component, and their positions correspond.

[0013] Secondly, the present invention also provides a method for using a special disassembly tool for the grinding roller of an automotive clutch steel sheet grinding equipment, comprising the following steps: Step 1: Insert the contour hole of the first fixing part into one end of the sand roller rotating shaft, and hold the handle of the first fixing part tightly to prevent the sand roller rotating shaft from rotating during disassembly; align the disassembly teeth of the first disassembly part with the groove on the first fixing nut, fully insert the nut, and turn the handle counterclockwise until the nut is loose; if the resistance is large, the torque can be increased by using an extension rod. After completely unscrewing the nut, remove the first fixing part and the first disassembly part.

[0014] Step 2: Attach the mounting plate of the second fixing part to the corresponding position on the back plate of the grinding equipment, fix it with fasteners through the mounting holes, and align the contour hole with the other end of the sand roller rotating shaft, insert and clamp the shaft body; align the disassembly teeth of the second disassembly part with the slot on the second fixing nut, hold the Z-shaped handle and rotate it counterclockwise until the nut is loosened and unscrewed. Step 3: After both the first and second fixing nuts are removed, clean and replace the sanding roller; put the sanding roller back onto the rotating shaft, align it with the installation position, manually pre-tighten the second fixing nut until it fits, use the second disassembly tool, insert the disassembly teeth into the nut slot, align the second fixing tool with the other end of the sanding roller rotating shaft through the contour hole of the second fixing tool, and rotate the Z-shaped handle clockwise until the nut is tight; manually pre-tighten the first fixing nut, hold the handle of the first fixing tool, use the first disassembly tool, and rotate the handle clockwise to lock it.

[0015] As a further implementation, when the resistance is high during the rotation of the first and second disassembly components, an extension rod is used to increase the torque.

[0016] Compared with the prior art, the advantages and positive effects of this invention are: Both the first and second fixing members of this invention are provided with contour holes that mate with the rotating shaft of the sand roller. The first fixing member manually restricts the rotation of the sand roller shaft, and the second fixing member, fixed to the back plate and mates with the contour holes, also restricts the rotation of the sand roller shaft. Both the first and second disassembly members are provided with disassembly teeth, which allow the first and second fixing nuts to be disassembled by rotating the disassembly teeth. The first fixing member manually restricts the shaft rotation, and the first disassembly member simultaneously loosens / tightens the nuts, solving the problem of the shaft rotating with the nuts when operating at the suspended end. The second fixing member automatically locks the shaft by being rigidly fixed to the back plate. The contour holes on the first and second fixing members precisely match the cross-section of the sand roller shaft, achieving a gapless circumferential lock, preventing tool slippage or damage to the shaft end during high-torque disassembly, and freeing up one hand for the operator to operate the Z-shaped handle of the second disassembly member with both hands for more effective force application. The two actions of loosening the nuts and preventing rotation are seamlessly completed by the same person or tool group, avoiding the trouble of multiple people working together or repeatedly searching for the point of force, and significantly shortening the disassembly and installation time.

[0017] The second disassembly component of this invention has a Z-shaped handle at one end of the transition cylinder and the disassembly teeth at the other end of the first drive cylinder. Due to the limited space caused by the sand roller's rotating shaft being embedded inside the back plate, the design of the second disassembly component with the transition cylinder and Z-shaped handle effectively allows for access to narrow spaces and torque transmission, solving the problem of conventional tools being unable to operate. The second fixing component is firmly connected to the equipment back plate via a mounting plate, forming a stable reaction force fulcrum. This ensures that the reaction force when disassembling the second fixing nut is directly borne by the equipment body, rather than by the operator's muscles, thus ensuring the rigidity of the operation process.

[0021] It should be noted that the following detailed description is illustrative and intended to provide further explanation of the invention. Unless otherwise specified, all technical and scientific terms used in this invention have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains.

[0022] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the scope of exemplary embodiments according to the invention. As used herein, unless otherwise expressly indicated by the invention, the singular form is also intended to include the plural form. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof. Example 1 This embodiment provides a special disassembly tool for the grinding roller of an automotive clutch steel sheet grinding equipment, such as... Figures 1-6 As shown, the device includes: a first fixing member 1 mounted on the sanding roller rotating shaft 5; a first disassembly member 2 mounted on the first fixing nut 4 of the sanding roller rotating shaft 5; a second fixing member 8 mounted on the back plate of the grinding equipment; and a second disassembly member 9 sleeved on the second fixing nut 6 of the sanding roller rotating shaft 5. Both the first fixing member 1 and the second fixing member 8 are provided with contour holes 15, which cooperate with the sanding roller rotating shaft 5. The first fixing member 1 manually restricts the rotation of the sanding roller rotating shaft 5, and the second fixing member 8 restricts the rotation of the sanding roller rotating shaft 5 by fixing it to the back plate and cooperating with the contour holes 15. Both the first disassembly member 2 and the second disassembly member 9 are provided with disassembly teeth 12, which can be used to disassemble the first fixing nut 4 and the second fixing nut 6 by rotating the disassembly teeth 12. The first fixing member 1 manually restricts the shaft rotation, and the first disassembly member 2 simultaneously loosens / tightens the nut, solving the problem of the shaft rotating with the nut when operating at the suspended end. The second fixing component 8 automatically locks the shaft by being rigidly fixed to the back plate. The contour holes 15 on the first and second fixing components 8 precisely match the cross-section of the sand roller rotating shaft 5, achieving a gapless circumferential lock. This prevents tool slippage or damage to the shaft head during high-torque disassembly, while also freeing up one hand for the operator to operate the Z-shaped handle 13 of the second disassembly component 9 with both hands for more effective force application. The loosening of the nut and the anti-rotation action are seamlessly completed by the same person or tool group, avoiding the trouble of multiple people working together or repeatedly searching for the leverage point, and significantly shortening the disassembly and installation time.

[0023] As a further implementation, the first disassembly component 2 includes a first drive cylinder 17, a handle disposed at one end of the first drive cylinder 17, and the disassembly teeth 12 disposed at the other end of the first drive cylinder 17.

[0024] As a further implementation, the first fixing member 1 includes a first fixing cylinder 18, the end of which is provided with the contour hole 15. The contour hole 15 is precisely matched with the cross section of the sand roller rotating shaft 5 to achieve a gapless circumferential lock, thereby forming a stable reaction force fulcrum.

[0025] As a further implementation, the second disassembly component 9 includes a second drive cylinder 10, a transition cylinder 11 disposed at the end of the second drive cylinder 10, a Z-shaped handle 13 disposed at the end of the transition cylinder 11, and the disassembly teeth 12 disposed at the other end of the second drive cylinder 10. Due to the structural characteristics of the sand roller rotating shaft 5 being embedded inside the back plate and having limited space, the design of the second disassembly component 9 with the transition cylinder 11 and the Z-shaped handle 13 can effectively penetrate narrow spaces and transmit torque, solving the problem that conventional tools cannot perform the operation.

[0026] As a further implementation, the second fixing member 8 includes a fixing plate 14 and a mounting plate 16. One end of the fixing plate 14 is provided with the contour hole 15, and the other end is fixedly connected to the mounting plate 16. The shape of the mounting plate 16 is adapted to the shape of the back plate of the grinding equipment, and both ends of the mounting plate 16 are provided with mounting holes, in which fasteners are provided. The mounting plate 16 is fixedly connected to the back plate of the grinding equipment through the fasteners. The second fixing member 8 is firmly connected to the back plate of the equipment through the mounting plate 16, forming a stable reaction force fulcrum, so that the reaction force when disassembling the second fixing nut 6 is directly borne by the equipment body, rather than by the operator's muscles, ensuring the rigidity of the operation process.

[0027] As a further implementation, the sanding roller 7 is fixedly connected to the middle of the sanding roller rotating shaft 5 by the second fixing nut 6. A sliding seat 3 is provided at one end of the sanding roller rotating shaft 5. The sliding seat 3 is set in the mounting frame of the back plate of the grinding equipment. The sanding roller rotating shaft 5 is mounted on the sliding seat 3 by the first fixing nut 4.

[0028] As a further implementation, the first fixing member 1, the first disassembly member 2, the second fixing member 8, the second disassembly member 9, and the disassembly tooth 12 are all formed by stamping or cutting steel and welding.

[0029] As a further implementation, the number of slots on the first fixing nut 4 is the same as the number of disassembly teeth 12 on the first disassembly component 2, and their positions correspond; the number of slots on the second fixing nut 6 is the same as the number of disassembly teeth 12 on the second disassembly component 9, and their positions correspond. The number and position of the disassembly teeth 12 correspond to the number of slots on the first fixing nut 4 and the second fixing nut 6, respectively, ensuring maximum contact area and uniform and direct torque transmission, reducing the risk of wear on tools and nuts.

[0030] Example 2 This embodiment provides a method for using a special disassembly tool for the grinding roller 7 of an automotive clutch steel sheet grinding equipment, including the following steps: Step 1: Insert the contour hole 15 of the first fixing part 1 into one end of the sand roller rotating shaft 5, and hold the handle of the first fixing part 1 tightly to prevent the sand roller rotating shaft 5 from rotating during disassembly; align the disassembly teeth 12 of the first disassembly part 2 with the slot on the first fixing nut 4, fully insert the nut, and rotate the handle counterclockwise until the nut is loose; if the resistance is large, the torque can be increased by using an extension rod. After completely unscrewing the nut, remove the first fixing part 1 and the first disassembly part 2.

[0031] Step 2: Attach the mounting plate 16 of the second fixing part 8 to the corresponding position on the back plate of the grinding equipment, fix it with fasteners through the mounting holes, and align the contour hole 15 with the other end of the sand roller rotating shaft 5, insert and clamp the shaft body; align the disassembly teeth 12 of the second disassembly part 9 with the slot on the second fixing nut 6, hold the Z-shaped handle 13 and rotate it counterclockwise until the nut is loosened and unscrewed; Step 3: After the first fixing nut 4 and the second fixing nut 6 are removed, clean and replace the sanding roller 7; put the sanding roller 7 back onto the rotating shaft, align it with the installation position, manually pre-tighten the second fixing nut 6 until it fits, use the second disassembly piece 9 to engage the disassembly teeth 12 into the nut slot, align the contour hole 15 of the second fixing piece 8 with the other end of the sanding roller rotating shaft 5, and rotate the Z-shaped handle 13 clockwise until the nut is tight; manually pre-tighten the first fixing nut 4, hold the handle of the first fixing piece 1, and use the first disassembly piece 2 to lock it by rotating the handle clockwise.

[0032] As a further implementation, when the resistance is high during the rotation of the first disassembly component 2 and the second disassembly component 9, an extension rod is used to increase the torque. Both the handle of the first disassembly component 2 and the Z-shaped handle 13 of the second disassembly component 9 provide longer lever arms and more comfortable grip points, allowing the operator to apply torque in a safer and less strenuous posture. Using an extension rod further amplifies the torque, making it easier to remove stubborn nuts and reducing the risk of muscle strain or tool slippage due to excessive force.

[0033] While the specific embodiments of the present invention have been described above in conjunction with the accompanying drawings, this is not intended to limit the scope of protection of the present invention. Those skilled in the art should understand that various modifications or variations that can be made by those skilled in the art without creative effort based on the technical solutions of the present invention are still within the scope of protection of the present invention.
