Description

Technical field

[0001] The utility model relates to the technical field of disassembly tooling, in particular to a disassembly tooling. [Background Technology]

[0002] Spline connection is a common mechanical transmission connection method. It has the same function as flat keys, semicircular keys and oblique keys, which are all used to transmit mechanical torque. There are longitudinal keyways on the surface of the spline shaft, and the rotating parts on the shaft also have corresponding keyways, which can maintain synchronous rotation with the shaft. It is widely used in various mechanical equipment.

[0003] Initially, spline disassembly tools were mostly simple disassembly tools, such as crowbars and hammers, which relied on manpower and simple lever principles for operation. The disassembly efficiency was low and parts were easily damaged during the disassembly process. With the development of industry, more and more manufacturers began to design special spline disassembly tools, but the existing disassembly and assembly tools were complicated and inconvenient to operate, and some disassembly tools had short operating handles, which made disassembly laborious and time-consuming. Some disassembly and assembly tools required the cooperation of multiple people and the use of other auxiliary tools for operation, or some disassembly tools were prone to generating yaw torque during the disassembly process, doing useless work during the disassembly process. The coordinated operation of multiple people was required to prevent the spline shaft from being subjected to non-axial forces. [Utility Model Content]

[0004] In order to solve the technical problem that the existing disassembly tooling is inconvenient to operate, the utility model provides a disassembly tooling.

[0005] The solution to the technical problem of the present invention is to provide a disassembly tool including a support and a clamping head, wherein the support is provided with a receiving groove, the clamping head and the support are slidably connected in the receiving groove, and the clamping head is provided with a limiting groove for accommodating the spline shaft.

[0006] Preferably, the clamping head is provided with sliding grooves on both sides of the inner wall of the accommodating groove, and the disassembly tool also includes a guide pin arranged corresponding to the sliding groove, and a guide hole is provided on the support, and the guide pin passes through the guide hole and is connected to the sliding groove to realize the sliding connection between the clamping head and the support.

[0007] Preferably, a limiting protrusion engaged with the spline shaft is provided on one side of the limiting groove close to the spline shaft.

[0008] Preferably, the sliding groove is arranged along the length direction of the support and parallel to the axial direction of the spline shaft.

[0009] Preferably, the accommodating groove has an opening facing one side of the spline shaft.

[0010] Preferably, the disassembly tool further includes a disassembly portion with one end fixedly connected to the clamping head, and the disassembly portion drives the clamping head to slide along the length direction of the support.

[0011] Preferably, the disassembly portion is threadedly connected to the support.

[0012] Preferably, the disassembly portion includes a connecting rod, which is arranged along the sliding direction of the clamp and the support. A through hole is opened on the support corresponding to the connecting rod, and the connecting rod and the support are connected through the through hole.

[0013] Preferably, the disassembly portion further includes an operating handle, and one end of the connecting rod away from the support is fixedly connected to the operating handle.

[0014] Preferably, the connecting rod portion extends into the accommodating groove through the through hole and is fixedly connected to the clamp.

[0015] Compared with the prior art, the disassembly tool provided by the utility model has the following advantages:

[0016] 1. The disassembly tool provided in the embodiment of the present invention has a limit groove for clamping the spline shaft, and a receiving groove on the support so that the clamp head can slide freely in the support. The receiving groove provides a visual observation channel, which is convenient for observing and adjusting the position of the clamp head, simplifying the disassembly process. Through the sliding connection between the clamp head and the support, the spline shaft is guided to be uniformly stressed and maintained in the correct direction during disassembly, preventing it from shifting or tilting during the disassembly process, and greatly shortening the time required for disassembly. The sliding connection plays a guiding role in the disassembly of the spline shaft, allowing the spline shaft to maintain axial force during the disassembly process, avoiding useless work, reducing disassembly time, and improving work efficiency. During disassembly, the support has a main bearing surface that is in direct contact with the device to be disassembled. The bearing surface withstands a large extraction force, ensuring the stability of the entire disassembly process. The limit groove accurately accommodates the spline shaft, ensuring that the spline shaft remains stable along the axial direction during disassembly. Compared with a single fixed receiving space, the limit groove can adapt to spline shafts of different specifications, enhancing the versatility of the disassembly tool. The simple operating mechanism is suitable for all types of operators, improving the usability of the tool.

[0017] 2. In the disassembly tool provided in the embodiment of the present invention, the guide pin passes through the guide hole and is connected to the slide groove. The guide pin limits the movement of the clamping head inside the accommodating groove, so that the clamping head is always on the predetermined track, effectively reducing the vibration or swing of the clamping head during use; through the support of the guide pin, the force applied to the clamping head is dispersed to the support, thereby increasing the carrying capacity of the tool; the sliding connection between the support and the clamping head is simple and easy to operate, and the simplified structure enables inexperienced operators to get started, thereby improving work efficiency.

[0018] 3. The disassembly tool provided in the embodiment of the present invention has a limiting protrusion that fixes the spline shaft in a predetermined position, ensuring that the spline shaft always maintains a correct centering state during the disassembly process. The limiting protrusion limits the spline shaft and surrounds the spline shaft, evenly dispersing the resistance encountered during disassembly, and preventing the spline shaft from breaking during disassembly.

[0019] 4. The disassembly tool provided in the embodiment of the present invention has a clamping head that slides smoothly along the length direction of the support and applies force evenly, thereby maintaining the stability of the tooling and preventing the spline shaft from shifting during the disassembly process. The clamping head is parallel to the axial direction of the spline shaft so that the sliding direction of the clamping head is consistent with the installation direction of the spline shaft, reducing friction and enabling the support to be quickly connected to the spline shaft, thereby improving the smoothness of disassembly.

[0020] 5. The disassembly tool provided in the embodiment of the present invention has an opening that allows the clamping head to be screwed out of the accommodating space of the support accommodating groove. The spline shaft usually has a fixing portion that can be fixed. The clamping head is screwed out of the accommodating groove to facilitate the limiting protrusion to be clamped to the fixing portion of the spline shaft from the side, thereby avoiding pressure loss on the spline shaft itself.

[0021] 6. The disassembly tool provided in the embodiment of the present invention has a disassembly part that drives the clamping head to slide along the length direction of the support, providing a force application path for the user, simplifying the operation, and accelerating the disassembly process. The disassembly part can be designed as different disassembly devices according to different disassembly needs, and is suitable for a variety of disassembly environments.

[0022] 7. The disassembly tool provided in the embodiment of the present invention has a threaded connection that improves the rigidity and stability of the overall structure, ensures that the disassembly part is not easily deformed during the disassembly process, and can continuously apply force to speed up the disassembly.

[0023] 8. In the disassembly tool provided in the embodiment of the present invention, the connecting rod and the support are connected through a through hole in a fixed position. The connecting rod is not easy to fall off during the disassembly process, thereby increasing the overall stability; the connecting rod can rotate in the through hole to realize the driving effect of the disassembly part on the clamping head.

[0024] 9. The disassembly tool provided in the embodiment of the present invention has an operating handle that provides a comfortable gripping position. The operating handle helps to disperse the force application points, reduce the burden on the hands, and make it easier for the operator to apply force, thereby effectively controlling the disassembly process.

[0025] 10. The disassembly tool provided in the embodiment of the present invention has a connecting rod fixed to the clamping head through a receiving groove, which can effectively transfer the force applied during the operation directly to the clamping head. The connecting rod is tightly connected to the clamping head, which improves the disassembly efficiency and reduces errors during the disassembly process.

For example, they can refer to fixed connections, removable connections, or integral structures; mechanical connections or electrical connections; direct connections, indirect connections through an intermediary, or internal communication between two devices, elements, or components. Those skilled in the art will understand the specific meanings of these terms in this utility model based on the specific circumstances.

[0040] See also Figure 1-Figure 2 The first embodiment of the utility model provides a disassembly tool 100 for disassembling a spline shaft 200 installed on a device. The disassembly tool 100 includes a support 1 and a clamping head 2. The support 1 is provided with a receiving groove 11. The clamping head 2 is slidably connected to the support 1 in the receiving groove 11. The clamping head 2 is provided with a limiting groove 21 for accommodating the spline shaft 200.

[0041] It can be understood that the limiting groove 21 on the chuck 2 clamps the spline shaft 200, and the receiving groove 11 provides a visual observation channel, which is convenient for observing and adjusting the position of the chuck 2. The receiving groove 11 allows the chuck 2 to slide freely in the support 1, greatly shortening the time required for disassembly. The sliding connection serves as a guide for the disassembly of the spline shaft 200, allowing the spline shaft 200 to maintain axial force during the disassembly process, avoiding useless work and improving the work efficiency of the disassembly process.

[0042] The support 1 and the clamping head 2 can fit well with the end face of the device to be disassembled, and are made of low-strength steel to avoid crushing the spline shaft 200.

[0043] Specifically, the width and depth of the accommodating groove 11 on the support 1 match the size of the clamping head 2, ensuring that the clamping head 2 has enough space when sliding but will not become loose. The bottom of the support 1 has sufficient strength and stability to withstand the reaction force during the entire disassembly process.

[0044] A precise sliding fit is provided between the clamping head 2 and the receiving groove 11 to ensure that the clamping head 2 can move smoothly in the receiving groove 11 without generating an excessive gap.

[0045] Furthermore, the depth of the limit groove 21 should be deep enough and opened on one of the side surfaces of the chuck 2 to completely surround the spline shaft 200 and provide stable mechanical support. Its shape matches the cross-section of the spline shaft 200 to ensure that the shaft body can be firmly placed in the limit groove 21 to avoid sliding during the disassembly process. Compared with opening a single fixed accommodation space, the limit groove 21 can adapt to spline shafts 200 of different specifications, thereby enhancing the versatility of the disassembly tool 100.

[0046] Optionally, a guide structure and a stop structure may be provided in the receiving groove 11 to ensure that the chuck 2 always remains stable and centered during the sliding process and to prevent the chuck 2 from sliding out of the receiving groove 11 .

[0047] Furthermore, a sliding groove 22 is provided on both sides of the inner wall of the chuck 2 relative to the accommodating groove 11, and the disassembly tool 100 also includes a guide pin 3 arranged corresponding to the sliding groove 22. A guide hole 12 is provided on the support 1, and the guide pin 3 passes through the guide hole 12 and is connected to the sliding groove 22 to realize the sliding connection between the chuck 2 and the support 1.

[0048] Optionally, corresponding protrusions can be provided on the support 1 to cooperate with the slide groove 22 to achieve the same guiding function as the guide pin 3; raised slide rails can also be provided on both sides of the clamping head 2 facing the wall of the accommodating groove 11 to achieve the same sliding function as the slide groove 22.

[0049] It can be understood that the slide groove 22 allows the chuck 2 to slide smoothly in the support 1 while ensuring its stability during the disassembly process. The position of the guide hole 12 corresponds to the slide groove 22, ensuring that the guide pin 3 can smoothly pass through the guide hole 12 and abut against the slide groove 22, while preventing the chuck 2 from shaking laterally in the accommodating groove 11.

[0050] Specifically, both sides of the clamping head 2 are provided with sliding grooves 22 of appropriate shapes, usually with a U-shaped or rectangular cross-section, to adapt to the shape of the guide pin 3 and ensure the fitting accuracy during sliding.

[0051] The diameter of the guide pin 3 should match the diameter of the guide hole 12, and the end face shape of the guide pin 3 should be suitable for the shape of the slide groove 22, such as cylindrical, so that the guide pin 3 can slide freely in the slide groove 22. The length and movable range of the guide pin 3 should match the length and depth of the slide groove 22 to ensure that the chuck 2 can slide fully in the accommodating groove 11 without falling off.

[0052] Furthermore, the guide pin 3 and the slide groove 22 are clearance-fitted.

[0053] Furthermore, a limiting protrusion 23 that engages with the spline shaft 200 is provided on one side of the limiting groove 21 close to the spline shaft 200 .

[0054] Understandably, see Figure 3 - Figure 4 The spline shaft 200 usually has a fixing portion 300 for fixing, and the limiting protrusion 23 is snap-connected with the fixing portion 300. The limiting protrusion 23 cooperates with the limiting groove 21 as a simple locking mechanism on the clamping head 2, which can lock the spline groove when the clamping head 2 reaches the end face of the spline groove of the device to be disassembled. The limiting protrusion 23 surrounds the fixing portion 300 to achieve tight clamping of the spline shaft 200 and avoid the risk of the fixing portion 300 breaking during the disassembly process of the spline shaft 200.

[0055] Specifically, the fixing portion 300 of the spline shaft 200 is generally a recessed slot, and the size of the limiting protrusion 23 is slightly larger than the slot diameter of the fixing portion 300, ensuring that the limiting protrusion 23 can be smoothly inserted into the fixing portion 300 to form an effective snap connection.

[0056] Optionally, the chuck 2 may be provided with an adjustable clamping and locking mechanism to adapt to spline shafts 200 of different diameters or types and to ensure that the spline shaft 200 can be stably clamped during the disassembly process.

[0057] Furthermore, a spring device or a buffer structure may be provided between the limiting protrusion 23 and the fixing portion 300 to prevent excessive compressive force from directly acting on the spline shaft 200 .

[0058] Furthermore, the sliding groove 22 is arranged along the length direction of the support 1 and parallel to the axial direction of the spline shaft 200 .

[0059] It can be understood that the sliding direction of the chuck 2 is parallel to the axial direction of the spline shaft 200, so that the sliding direction of the chuck 2 is consistent with the installation direction of the spline shaft 200, ensuring that the spline shaft 200 is always subjected to axial pulling force during the disassembly process, and the disassembly tool 100 will not generate a yaw moment to subject the spline shaft 200 to non-axial force, thereby improving the stability of the disassembly process and enabling the support 1 to be quickly docked with the spline shaft 200, thereby improving the smoothness of disassembly.

[0060] For further information, see Figure 3 The spline shaft 200 is arranged along the axial direction in the device. Therefore, when the spline shaft 200 is disassembled, it is necessary to apply the same axial force to the spline shaft 200, and the disassembly tool 1 can be vertically abutted against the spline shaft 200.

[0061] Therefore, a mounting end surface 400 can be defined on a horizontal plane perpendicular to the mounting direction of the spline shaft 200 .

[0062] During disassembly, the disassembly tool 100 is vertically installed on the mounting end face 400, the support 1 fits tightly against the mounting end face 400, and the fitting surface abutting against the mounting end face 400 bears the main pull-out force during the disassembly process. The fitting surface has a large surface area to evenly distribute the force, ensuring that no slippage occurs under the force state, and ensuring that the spline shaft 200 is always subjected to axial pull-out force during the disassembly process.

[0063] Specifically, the disassembly tool 100 provided by the utility model is suitable for disassembling a spline shaft 200 installed in a hydraulic pump. At this time, the mounting end face 400 is the end face of the hydraulic pump mounting flange. The support 1 on the disassembly tool 100 is in close contact with the mounting end face 400 to ensure the stability of the clamping head 2 and the spline shaft 200 during the disassembly process and prevent tilting and offset.

[0064] Specifically, the length of the slide groove 22 is consistent with the length of the clamping head 2, ensuring that the clamping head 2 can be stably supported throughout the entire disassembly range.

[0065] Furthermore, an inner chamfer is provided on one side of the support 1 close to the end face of the spline shaft 200 to avoid contact with protruding bolts or other components on the device to be disassembled, thereby improving safety.

[0066] Furthermore, the accommodating groove 11 has an opening 13 facing one side of the spline shaft 200 .

[0067] It can be understood that the opening 13 allows the clamp 2 to be screwed out of the accommodating space of the support 1 accommodating groove 11. Screwing the clamp 2 out of the accommodating groove 11 makes it easier for the limiting protrusion 23 to be clamped to the fixing part 300 of the spline shaft 200 from the side, forming a snap connection, effectively avoiding pressure loss on the spline shaft 200 itself.

[0068] Specifically, the sliding groove 22 is aligned with the opening 13 , and the rotational movement of the chuck 2 can smoothly transition from the interior of the receiving groove 11 to the area of the opening 13 .

[0069] According to the flexible design of the disassembly requirements, the length of the accommodating groove 11 is adapted to the spline shafts 200 of different lengths and specifications, thereby improving the versatility of the disassembly tool 100.

[0070] See also Figure 1Furthermore, the opening 13 is provided on one side of the support 1 close to the end face of the spline shaft 200, and the opening 13 is provided with an inner chamfer to avoid touching the protruding bolts or other parts on the device to be disassembled, thereby improving safety.

[0071] Furthermore, the disassembly tool 100 further includes a disassembly portion 4 , one end of which is fixedly connected to the clamping head 2 , and the disassembly portion 4 drives the clamping head 2 to slide along the length direction of the support 1 .

[0072] It can be understood that the disassembly portion 4 is fixedly connected to the clamping head 2 by means of threads, snaps or plug-ins, ensuring that it will not loosen during the disassembly process.

[0073] Optionally, the disassembly portion 4 can be designed as different disassembly devices according to different disassembly needs, such as a manual disassembly portion 4 connected by threads, a hydraulic disassembly portion 4 guided by a hydraulic device, or a spring disassembly portion 4 using a spring drive mechanism, which is suitable for a variety of disassembly environments. In this embodiment, no specific limitation is made, as long as the driving effect on the chuck 2 can be achieved.

[0074] Furthermore, the disassembly portion 4 is threadedly connected to the support 1 .

[0075] Furthermore, the disassembly portion 4 includes a connecting rod 41 , which is arranged along the sliding direction of the clamping head 2 and the support 1 . A through hole 14 is opened on the support 1 corresponding to the connecting rod 41 , and the connecting rod 41 is connected to the support 1 through the through hole 14 .

[0076] It can be understood that the connecting rod 41 is connected to the support 1 through the through hole 14 at a fixed position. The connecting rod 41 is not easy to fall off during the disassembly process, which increases the overall stability and safety.

[0077] Specifically, the connecting rod 41 can rotate in the through hole 14 to realize the driving effect of the disassembly portion 4 on the chuck 2 .

[0078] Furthermore, the disassembly portion 4 further includes an operating handle 42 , and one end of the connecting rod 41 away from the support 1 is fixedly connected to the operating handle 42 .

[0079] It can be understood that the operating handle 42 is lengthened to provide a good grip without adding unnecessary weight.

[0080] Optionally, the operating handle 42 and the connecting rod 41 can be fixed with bolts or pins. To facilitate transportation and storage disassembly, they can also be fixed with a simple buckle or rotation locking mechanism.

[0081] Furthermore, a portion of the connecting rod 41 extends into the receiving groove 11 through the through hole 14 and is fixedly connected to the clamping head 2 .

[0082] It can be understood that the connecting rod 41 is fixed to the clamp 2 through the accommodating groove 11, which can effectively transfer the force applied during the operation directly to the clamp 2. The connecting rod 41 and the clamp 2 can adopt an integrated design to form a tight connection, or they can be fixed with bolts, clamped or other detachable fixing methods for easy maintenance.

[0083] The specific operation process of the disassembly tool 100 provided in this embodiment is as follows: first, rotate the connecting rod 41 through the operating handle 42 to screw the clamping head 2 out of the support 1 until it abuts against the end face of the spline shaft 200, so that the limiting groove 21 is clamped into the spline shaft 200 from the side, and the limiting protrusion 23 clamps the fixed part 300 of the spline shaft 200. Rotate the operating handle 42 in the opposite direction to drive the clamping head 2 to move to the side away from the end face of the spline shaft 200 until the spline shaft 200 is completely disengaged from the device to be disassembled, and the disassembly is completed.
