Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicles, and particularly relates to a dismounting tool. BACKGROUND

[0002] In existing vehicles, the outer ring of a tapered roller bearing is usually installed on a related structural member with independent interference. When dismounting, a technician needs to use a special dismounting tool to dismount the outer ring from the related structural member.

[0003] The existing dismounting tool comprises two pull blocks used for fixedly clamping the outer ring and a pull rod used for applying a pulling force to the pull blocks. The two pull blocks enclose an inner cavity, the pull rod is a stepped shaft and is inserted between the two pull blocks, and the shaft shoulder of the pull rod abuts against the inner cavity enclosed by the pull blocks in the direction in which the outer ring is pulled out. When in use, a wrench or the like is used to apply a pulling force to the pull rod, so that the pull rod drives the fixed member to pull out the outer ring.

[0004] Due to the lack of effective limiting between the two pull blocks, the two pull blocks are prone to relative tilting between them when pulling. This easily causes the pull blocks to disengage from the clamping of the outer ring when pulling, thereby affecting the operation efficiency of the dismounting operation; meanwhile, it also aggravates the wear of the pull blocks when in use, so that the service life of the dismounting tool is significantly reduced. CONTENT OF THE UTILITY MODEL

[0005] In view of the above problems, the utility model is provided to provide a dismounting tool which overcomes the above problems or at least partially solves the above problems.

[0024] In this embodiment, the disassembly fixture specifically includes a rod, a limiting member, and two first fixing members. Each of the two first fixing members has a mounting groove, in which the rod is installed, allowing the first fixing member to move by lifting the rod. The locking structure of the first fixing member engages with the part to be disassembled, enabling the part to be disassembled to detach from its original structure. The limiting member connects the two first fixing members, ensuring the rod fits snugly against the mounting groove. During disassembly, the two first fixing members are less prone to relative tilting under the support of the rod. Therefore, the locking structure of the first fixing member maintains a stable engagement with the part to be disassembled, reducing the likelihood of connection failure. This prevents the disassembly fixture from slipping off the part during disassembly, effectively ensuring the efficiency of the disassembly operation. Simultaneously, this also avoids wear and tear on the disassembly fixture caused by slippage, effectively extending its service life.

[0037] In the description of the utility model, it needs to explain, unless another explicit provision and limitation, the term "installation", "connection", "connection" should do the broad sense understanding, for example, can be fixed connection, also can be detachable connection, or integrally connected, can be mechanical connection, also can be electrical connection, can be direct connection, also can be indirectly connected through the intermediate medium, can be the intercommunication of two elements.

[0038] The tapered roller bearing has higher load capacity, adjustable relative position of inner and outer rings, longer service life and other advantages, and is widely used in vehicles and related parts. The inner ring and the outer ring of the existing tapered roller bearing are separable. When installing, the outer ring of the tapered roller bearing is fixedly installed on the external structure, and the inner ring is pressed on the surface of the outer ring by other structures. This also means that when disassembling the tapered roller bearing, the outer ring must be disassembled from the external structure. Since the outer ring structure is small, it is not convenient to apply force. Therefore, the technician needs to use a disassembly tool to disassemble the outer ring of the tapered roller bearing.

[0039] The existing disassembly tool for disassembling the outer ring of the tapered roller bearing generally includes two pull blocks for fixing and clamping with the outer ring, and a pull rod for applying pulling force to the fixing member. The two pull blocks enclose an inner cavity, and the pull rod is a stepped shaft and is inserted between the two pull blocks. The shaft shoulder of the pull rod abuts the inner cavity enclosed by the pull blocks in the direction in which the outer ring is pulled out. When using, a wrench or other tool is used to apply pulling force to the pull rod to make the pull rod drive the fixing member to pull out the outer ring. Since there is no effective limiting between the two pull blocks, the two pull blocks are prone to relative tilting when pulling. This can easily cause the pull block to disengage from the clamping of the outer ring, thereby affecting the operation efficiency of the disassembly operation. At the same time, the slipping problem between the pull block and the outer ring can also aggravate the wear of the pull block, which significantly reduces the service life of the disassembly tool.

[0040] Therefore, the present application provides a new disassembly tool.

[0041] Referring to Figure 1 , Figure 2 and Figure 5 , a disassembly tool according to an embodiment of the present application is shown. The disassembly tool described in the present application comprises two first fixing members 1, and the two first fixing members 1 are arranged in a spaced manner along a first direction X. An installation slot 11 is formed on each of the two first fixing members 1, and the two installation slots 11 are opposite in the first direction X.

[0042] Referring to Figure 2 and Figure 3The dismounting tool further comprises a rod 2. The rod 2 is installed between the two installation grooves 11 so as to transmit the pulling force received by the rod 2 to the first fixing member 1. In the present application, the installation between the rod 2 and the installation groove 11 can be implemented in various ways. For example, the installation between the rod 2 and the installation groove 11 can be implemented by structural connection, such as setting a protrusion on the rod 2 and a pit on the installation groove 11, and installing the rod 2 between the two installation grooves 11 by clamping cooperation between the protrusion and the pit. For another example, the installation between the rod 2 and the installation groove 11 can also be implemented by connecting the rod 2 with a connecting member. Regardless of the implementation, the rod 2 and the installation groove 11 are in close contact with each other during the dismounting operation, so as to limit the movement of the two first fixing members 1 by cooperation between the rod 2 and the installation groove 11. When the two first fixing members 1 have a tendency to move away from each other or to tilt away from each other, the rod 2 can provide support and limit for the two first fixing members 1 to prevent the movement or tilting tendency of the first fixing members 1.

[0043] With reference to Figure 3 The dismounting tool further comprises a limiting member 3. The limiting member 3 is connected between the two first fixing members 1 to prevent the tendency of the two first fixing members 1 to move away from each other or to tilt away from each other. During the dismounting operation, the clamping structure 12 of the two first fixing members 1 is clamped and cooperated with the to-be-dismounted member, and the limiting member 3 keeps the two first fixing members 1 together, while the installation groove 11 on the two first fixing members 1 is in close contact with the rod 2. At this time, under the limitation of the limiting member 3 and the rod 2, the relative position and posture of the two first fixing members 1 will not change, so that the clamping structure 12 of the two first fixing members 1 is not easy to slip off the to-be-dismounted member. In this way, the work efficiency of the dismounting operation can be effectively ensured. At the same time, the problem of wear and tear of the dismounting tool caused by slipping can be avoided, and the service life of the dismounting tool can be effectively prolonged.

[0044] It should be noted that the installation groove 11 can be a rectangular groove with a rectangular cross section, and correspondingly, the rod 2 can be a square rod with a square cross section. The installation groove 11 can also be a semicircular groove with a semicircular cross section, and correspondingly, the rod 2 can be a circular rod with a circular cross section. In other words, the specific shape and size of the installation groove 11 and the rod 2 depend on the actual dismounting needs. The to-be-dismounted member can be specifically a cone roller bearing outer ring 200, or other similar structures, such as a self-lubricating copper sleeve installed in a hole with interference.

[0045] With reference to Figure 4In some embodiments of the present application, the rod member 2 specifically comprises a first rod body 2a and a second rod body 2b. The first end of the first rod body 2a extends out of the mounting groove 11 to serve as a force receiving end to bear the pulling force. The second end of the first rod body 2a is located in the mounting groove 11 and is fixedly connected with the first end of the second rod body 2b. The second rod body 2b has a first tapered surface 21, and the diameter of the first end of the second rod body 2b is smaller than the diameter of the second end of the second rod body 2b.

[0046] With reference to Figure 6 Correspondingly, the mounting groove 11 comprises a first portion 111 and a second portion 112. The groove type and cross-sectional size of the first portion 111 are adapted to the first rod body 2a to ensure that the first portion 111 can be in close contact with the first rod body 2a. The second portion 112 has a second tapered surface 1121 which is in close contact with the first tapered surface 21. When the first end of the rod member 2 bears the pulling force, the pulling force is transmitted to the position where the first tapered surface 21 and the second tapered surface 1121 are in close contact through the first rod body 2a and the second rod body 2b. The pulling force exerted by the first tapered surface 21 on the second tapered surface 1121 can be orthogonally decomposed into a component force perpendicular to the second tapered surface 1121. This component force can ensure that the first tapered surface 21 and the second tapered surface 1121 have a good close contact relationship, so as to further limit the relative position and attitude between the two first fixing members 1 through the close contact between the first tapered surface 21 and the second tapered surface 1121.

[0047] In addition, even if any one of the first tapered surface 21 and the second tapered surface 1121 is worn or deformed when the rod member 2 is pulled, the first tapered surface 21 and the second tapered surface 1121 can still maintain a good close contact relationship under the action of the pulling force. This can avoid the installation and cooperation relationship between the pull rod and the mounting groove 11 being invalid due to wear and deformation of the contact position, thereby being beneficial to guarantee the service life of the dismounting tool.

[0048] With reference to Figure 2 In some embodiments of the present application, the clamping structure 12 is located at the end of the first fixing member 1 away from the first end of the first rod body 2a. On this basis, the distance between the end with smaller diameter of the second tapered surface 1121 and the clamping structure 12 is a first size A along the axial direction of the rod member 2, and the size of the first fixing member 1 along the axial direction of the rod member 2 is a second size B. The ratio of the first size A to the second size B is not less than 1 / 4 and not greater than 1 / 3. In this way, the first tapered surface 21 and the second tapered surface 1121 can be as close to the clamping structure 12 as possible, thereby increasing the size and contact area of the first rod body 2a of the rod member 2 and the first portion 111 of the mounting groove 11. This can increase the close contact area between the rod member 2 and the mounting groove 11 to further improve the limiting effect between the rod member 2 and the mounting groove 11.

[0049] The ratio between the first size A and the second size B can be set according to actual needs. For example, the ratio between the first size A and the second size B can be 1 / 4, 1 / 3, 7 / 24, or any value between 1 / 4 and 1 / 3.

[0050] With reference to Figure 6 In some embodiments of the present application, the first fixing member 1 is provided with an avoiding groove 13. The avoiding groove 13 extends in the same direction as the mounting groove 11, and the size of the avoiding groove 13 is greater than or equal to the maximum rod diameter of the rod member 2. The avoiding groove 13 is in communication with the mounting groove 11. When assembling or disassembling the tool, the second rod body 2b of the rod member 2 can first pass into the avoiding groove 13 and then move to the mounting groove 11 through the avoiding groove 13. This is conducive to improving the convenience of disassembling the rod member 2, thereby effectively improving the assembly efficiency of the disassembly tool, and further improving the overall efficiency of the disassembly operation.

[0051] With reference to Figure 3 , Figure 4 In some embodiments of the present application, the disassembly tool further comprises a second fixing member 4 and a threaded member 5. The second fixing member 4 can be fixedly connected with the external structure 100, so as to serve as the mounting base and stress base of the entire disassembly tool. The second fixing member 4 and the external structure 100 can be fixedly connected by welding, fastener connection, adhesion, or other ways, which will not be described here. The threaded member 5 is mounted on the second fixing member 4 and has an internal thread structure 51. Corresponding to the internal thread structure 51 of the threaded member 5, the second fixing member 4 can be provided with an avoiding structure for avoiding the rod member 2. The rod member 2 is provided with an external thread structure 22, and the external thread structure 22 of the rod member 2 cooperates with the internal thread structure 51 of the threaded member 5 to realize the threaded connection between the rod member 2 and the threaded member 5.

[0052] When the dismounting operation is performed, the clamping structure 12 of the first fixing member 1 is clamped and matched with the to-be-dismounted member, the first conical surface 21 of the rod member 2 is attached to the second conical surface 1121 of the installation groove 11, and the external thread structure 22 of the rod member 2 is threadedly matched with the internal thread structure 51 of the threaded member 5. At this time, a torque around the axis of the rod member 2 is applied to the rod member 2, so that the rod member 2 is rotated relative to the threaded member 5. Under the matching of the external thread structure 22 and the internal thread structure 51, the rod member 2 is synchronously moved along the axial direction of the rod member 2 relative to the threaded member 5, and synchronously lifts the first fixing member 1. The first fixing member 1 transmits the pulling force to the to-be-dismounted member, so that the to-be-dismounted member is separated from the external structure 100. The threaded connection between the rod member 2 and the threaded member 5 can save the force applied to the dismounting tool during the dismounting operation, so that greater convenience can be provided for the dismounting operation, and the working efficiency of the dismounting operation can be improved. In the present application, the threaded member 5 can specifically adopt a nut. Correspondingly, the second fixing member 4 can be provided with a limiting groove 43 for accommodating the nut. The limiting groove 43 has the same shape as the outer shape of the nut, so as to prevent the nut from rotating synchronously with the rod member 2 under the action of the friction force between the threads.

[0053] With reference to Figure 4 In some embodiments of the present application, the second fixing member 4 has an accommodating cavity 41, and the first fixing member 1 is arranged in the accommodating cavity 41. In order to facilitate the dismounting of the rod member 2, the second fixing member 4 has an avoiding opening 42. The avoiding opening 42 is in communication with the accommodating cavity 41, and the opening size of the avoiding opening 42 is not less than the maximum rod diameter of the rod member 2. When the dismounting tool is assembled, the rod member 2 can enter the accommodating cavity 41 from the avoiding opening 42, then enter the avoiding groove 13 of the first fixing member 1 from the accommodating cavity 41, and finally move from the avoiding groove 13 to the installation groove 11. The avoiding opening 42 facilitates the installation of the rod member 2, improves the convenience and assembly efficiency during the assembly of the dismounting tool, and thus is beneficial to improving the working efficiency of the entire dismounting operation. When the threaded member 5 adopts a nut, the aforementioned limiting groove 43 can be arranged at the avoiding opening 42. After the nut is installed into the limiting groove 43, the threaded hole on the nut, the avoiding opening 42 and the accommodating cavity 41 are in communication with each other.

[0054] With reference to Figure 2 , Figure 3In some embodiments of the present application, the dismounting tool comprises a compression spring 6. The compression spring 6 is arranged between the two first fixing members 1, and the axis of the compression spring 6 is arranged along the first direction X to hinder the mutual approaching movement tendency of the two first fixing members 1. In the unforced state, the compression spring 6 is braced between the two first fixing members 1. At this time, under the action of the compression spring 6 and the limiting member 3, the relative position between the two first fixing members 1 is determined, that is, the two first fixing members 1 are not easy to approach or move away from each other. When the clamping structure 12 is clamped with the to-be-dismounted member, the two first fixing members 1 will not have a large positional shift. In this way, the clamping of the clamping structure 12 with the to-be-dismounted member is facilitated, and the working efficiency of the dismounting operation is improved. In order to facilitate the installation of the compression spring 6, compression spring holes 15 can be formed on the two first fixing members 1, and the two ends of the compression spring 6 are respectively installed in the corresponding compression spring holes 15.

[0055] With reference to Figure 3 In some embodiments of the present application, the limiting member 3 can specifically be a fastener. The limiting member 3 can specifically be a screw, a bolt, a rivet or the like fastener. Preferably, in the present embodiment, the limiting member 3 specifically adopts a bolt and a nut. The first fixing member 1 is provided with a connecting hole 14, and the connecting holes 14 of the two first fixing members 1 are arranged opposite to each other along the first direction X. During assembly, the bolt passes through the connecting holes 14 of the two first fixing members 1, and the end of the bolt is threadedly connected with the nut. The two first fixing members 1 are limited between the bolt head of the bolt and the nut, and can only move within a certain range along the axial direction of the bolt. By using a bolt, a screw or the like fastener as the limiting member 3, the interval between the two first fixing members 1 can be conveniently adjusted; at the same time, the structure of the limiting member 3 can be simplified, and the design and production and processing costs can be reduced.

[0056] With reference to Figure 3 In some embodiments of the present application, a handle 23 can be arranged at the part of the rod member 2 extending out of the first fixing member 1. The presence of the handle 23 can facilitate the manual dismounting operation of the operator. Whether a pulling force along the axial direction of the rod member 2 is applied to the rod member 2 or a torque around the axial direction of the rod member 2 is applied to the rod member 2, the handle 23 can provide a good force application site. In this way, the ease of use of the dismounting tool is improved, and the convenience of the dismounting operation is improved.

[0057] With reference to Figure 1 In some embodiments of the present application, the clamping structure 12 is specifically a convex edge protruding from the surface of the first fixing member 1. The convex edge structure is simple, easy to process, and has good structural strength and is not easy to deform and fail during dismounting.

[0058] In the embodiments of the present application, the extension direction of the convex edge depends on the actual scene needs. For example, with reference to Figure 5Any of the first fixing members 1 has an outer arc surface on the side thereof facing away from the other first fixing member 1. A protruding edge can be arranged at the outer arc surface of the first fixing member 1 and extends radially outwardly along the arc surface. Alternatively, the protruding edge can be arranged at the end surface of the first fixing member 1 arranged in the axial direction and extends beyond the outer arc surface of the first fixing member 1 in a direction inclined to the axial direction of the first fixing member 1. Alternatively, the protruding edge can also be arranged at the surface of the first fixing member 1 facing the other first fixing member 1 and extends towards the other first fixing member 1. When disassembling, the protruding edges of the two first fixing members 1 are close to each other and are clamped from the outside of the part to be disassembled.

[0059] The existing tapered roller bearing has a certain gap between the outer ring 200 and the external structure 100 after being installed in place. When installing, an external force can be applied to the two first fixing members 1 to make the two first fixing members 1 overcome the reaction force of the compression spring 6 and approach each other. At this time, the two first fixing members 1 are installed in the inner cavity of the outer ring 200. Remove the external force, and the protruding edge is clamped into the gap between the outer ring 200 and the external structure 100. At this time, the rod member 2 is installed in the installation groove 11 of the first fixing member 1 from the avoiding groove 13 of the first fixing member 1, the first part 111 of the installation groove 11 is attached to the part of the rod member 2 without the external thread structure 22, and the first taper surface 21 of the rod member 2 is attached to the second taper surface 1121 of the installation groove 11. At this time, the limiting member 3 can be adjusted to ensure that the rod member 2 and the installation groove 11 do not disengage. The second fixing member 4 is fixedly installed on the external structure 100, and the rod member 2 is screwed with the threaded member 5 installed on the second fixing member 4. Rotate the handle 23 of the rod member 2, so that the rod member 2 can move along its own axis, and drive the two first fixing members 1 to move synchronously through the cooperation of the first taper surface 21 and the second taper surface 1121. The protruding edges of the two first fixing members 1 drive the outer ring 200 to move synchronously, so that the outer ring 200 is disconnected from the external structure 100 and the disassembly is completed. In this process, the relative position and posture of the two first fixing members 1 do not change due to the limitation of the limiting member 3 and the rod member 2, so the protruding edges of the two first fixing members 1 are not easy to slip off the outer ring 200. This can effectively ensure the work efficiency of the disassembly work. At the same time, this can also avoid the problem of wear and tear of the disassembly tool caused by slipping, thereby effectively prolonging the service life of the disassembly tool.
