Description

Technical Field

[0001] This utility model relates to the field of power transmission and transformation technology, and in particular to a wheel axle removal mechanism. Background Technology

[0002] In power transmission and transformation projects, the stringing pulley is the core equipment for tension stringing construction, used to support and guide the laying of conductors. Due to long-term exposure to tension, friction, and the complex outdoor environment, the pulley is prone to malfunctions such as pulley wear, bearing damage, structural deformation, and aging of electrical components. If pulley malfunctions are not repaired in time, it may lead to the stagnation of stringing construction, delays in the construction period, and increased safety risks, such as conductor jumping or breaking, and may even affect the progress and quality of the entire transmission line project.

[0003] The pulley has a complex structure, and maintenance requires disassembly, cleaning and inspection of each part. The process is very complicated and tedious. For example, when disassembling the pulley wheel and axle, it relies on manual removal. If the assembly is tight, it is even more inconvenient. If necessary, the bearing needs to be knocked off manually before the axle can be removed, which can easily damage the axle.

[0004] The information disclosed in this background section is intended only to enhance the understanding of the overall background of this utility model and should not be construed as an admission or in any way implying that the information constitutes prior art known to those skilled in the art. Utility Model Content

[0005] The technical problem to be solved by this utility model is to solve the problem of the difficulty in removing the wheel and axle.

[0006] This utility model solves the above-mentioned technical problems through the following technical means:

[0007] This utility model claims a wheel de-axle mechanism, including a worktable, a first clamping assembly, a tray assembly, a second clamping assembly, and a drive assembly. The worktable is provided with a placement hole, and a set of first clamping assemblies are symmetrically arranged at the opening of the hole. The tray assembly is arranged inside the placement hole, and the tray assembly has an insertion hole. The second clamping assembly is arranged at the lower opening of the insertion hole. The drive assembly is configured to drive the tray assembly to move linearly relative to the first clamping assembly along the depth direction of the insertion hole.

[0008] This invention uses a first clamping assembly and a second clamping assembly to fix the axle and the wheel piece to be processed, respectively. A drive assembly drives the axle and other wheel pieces to descend, thereby separating the axle, other wheel pieces, and the wheel piece to be processed. This allows the wheel pieces to be removed from the axle sequentially and quickly, replacing the inconvenience and complexity caused by manual operation. In addition, the second clamping assembly can align the wheel piece to be processed, ensuring that the wheel piece to be processed is always in the initial position, which is convenient for the robot to place and pick up, and facilitates the operation of the entire process.

[0009] Preferably, the tray assembly includes an upper tray with a through-hole in the center. A third gripper is provided on the lower surface of the upper tray, located on one side of the lower opening of the insertion hole. A second gripper is provided on the other side of the lower opening of the insertion hole. The second and third grippers are arranged opposite to each other. The third gripper is driven by a second power unit to move closer to or away from the second gripper, and the direction of movement is perpendicular to the depth of the insertion hole. The second power unit, the second gripper, and the third gripper together constitute the second clamping assembly.

[0010] The second clamping assembly is used to clamp the wheel axle.

[0011] Preferably, the tray assembly further includes a lower tray and a connecting plate. The lower tray is coaxially arranged below the upper tray and fixed to it by the connecting plate. The diameter of the lower tray is larger than that of the upper tray. The lower tray is provided with a fixed end of the third power unit, and the output end of the third power unit is connected to the bottom of the placement hole. A third guide unit is provided in the placement hole. The third guide unit and the lower tray form a guide fit along the depth direction of the insertion hole. The third guide unit and the third power unit together constitute a drive assembly.

[0012] The third guide unit is used for guidance, ensuring the movement direction and stability of the pallet assembly.

[0013] Preferably, it also includes a base, with a base provided at the bottom of the placement hole, and a guide shaft provided on the base. The axis of the guide shaft is parallel to the axis of the placement hole. The guide shaft is inserted into a sliding sleeve provided on the lower tray. The guide shaft is offset from the upper tray. The sliding sleeve and the guide shaft constitute a third guide unit.

[0014] There are four guide shafts arranged in a circular array along the axis of the placement hole to ensure uniform force distribution.

[0015] Preferably, the first clamping assembly includes an adjusting frame, an adjusting unit, a first guiding unit, and a first gripper. The adjusting frame is provided on the upper surface of the worktable and is located on one side of the placement hole opening. The first gripper is provided inside the adjusting frame and faces the placement hole. The first guiding unit is provided between the first gripper and the adjusting frame, and the guiding direction is perpendicular to the axis of the placement hole. The adjusting unit is configured to adjust the first gripper to move along the guiding direction.

[0016] A symmetrical arrangement of a set of first clamping components means that there are two first clamping components, which are arranged symmetrically along the axis of the placement hole. By having the clamping ends of the two first clamping components move closer or further away simultaneously, they clamp the wheel on both sides, thereby fixing the wheel and aligning its center.

[0017] Preferably, the adjustment frame has a U-shaped frame structure with the U-shaped opening facing the placement hole. The inner wall of the adjustment frame has recessed guide grooves or protruding guide blocks on both sides, which form a guide engagement with another protruding guide block or another recessed guide groove on both sides of the first gripper. The guide groove and the guide block form the first guide unit.

[0018] In fact, the guide groove and guide block mainly serve a guiding function.

[0019] Preferably, the end face of the adjustment bracket away from the placement hole passes through the screw hole, the screw hole engages with the screw rod, one end of the screw rod is adapted to the surface of the first jaw, and the other end of the screw rod is connected to the handle. The handle, the screw rod and the screw hole constitute the adjustment unit.

[0020] The screw adjustment is highly accurate and convenient, making it suitable for the adjustment and clamping required by this utility model.

[0021] Preferably, the surface of the first gripper facing the placement hole is a concave arc surface, and the corner of the concave arc surface is chamfered.

[0022] The curvature of the arc surface is preferably consistent with the curvature of the surface of the wheel piece to be treated. The arc surface is preferably chamfered, which on the one hand ensures that the first gripper fits the surface of the wheel piece to be treated to the greatest extent; on the other hand, it reduces obstruction when the first gripper is inserted into the side of the wheel piece to be treated.

[0023] Preferably, the insertion hole is a square hole structure, and the second clamping claw mounting seat is inserted into the square hole and fixed to each other by bolts.

[0024] To ensure that the second clamping assembly can stably clamp axles of different shapes and sizes, a second clamping jaw mounting base is inserted into the socket. The second clamping jaw is located on one side below the second clamping jaw mounting base. Therefore, the second clamping jaw is still located on one side of the socket. After insertion, the second clamping jaw mounting base and the socket are fixed to each other with bolts.

[0025] Preferably, both the third gripper and the second gripper are V-shaped block structures, and the V-shaped openings are opposite each other.

[0026] With the V-shaped openings facing each other, the two V-shaped blocks form a clamping space. Attached Figure Description

[0037] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below in conjunction with the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0038] See Figure 1 and Figure 2 This utility model claims a wheel axle removal mechanism for removing the axle from the wheel to be processed, and ensuring that the wheel to be processed is always in the initial position, so as to facilitate the robot to place and pick up, and to facilitate the operation of the whole process. The wheel axle removal mechanism includes a worktable 1, a first clamping assembly, a tray assembly, a second clamping assembly, a base 6, and a drive assembly.

[0039] The workbench 1 can be a single piece or a separate piece. Taking the separate piece as an example, the workbench 1 includes a support platform and an operating platform. The support platform is at the bottom, and a first placement hole 10 is opened on the support platform. The operating platform is fixed on the upper surface of the support platform, and a second placement hole 10 passes through the operating platform. The diameter of the second placement hole 10 and the diameter of the first placement hole 10 can be different, but preferably the diameter of the first placement hole 10 is larger than the diameter of the second placement hole 10. The diameter of the second placement hole 10 is larger than the diameter of the wheel piece to be processed. During installation, it is necessary to ensure that the first placement hole 10 and the second placement hole 10 are coaxial.

[0040] When the workbench 1 is an integral piece, the workbench 1 is provided with a placement hole 10, and a set of first clamping components are symmetrically arranged at the opening of the hole. The symmetrical arrangement of a set of first clamping components means that there are two first clamping components, which are arranged symmetrically along the axis of the placement hole 10. By the two first clamping components moving closer or further away at the clamping ends, they clamp the wheel on both sides, thereby fixing the wheel and aligning its center.

[0041] The first clamping assembly is used to clamp the wheel piece to be processed. Specifically, the first clamping assembly includes an adjustment frame 20, an adjustment unit, a first guide unit, and a first gripper 23. The adjustment frame 20 is provided on the upper surface of the worktable 1. The adjustment frame 20 is located on one side of the opening of the placement hole 10. The adjustment frame 20 is preferably a U-shaped frame structure, and the U-shaped opening faces the placement hole 10.

[0042] The U-shaped opening facing the placement hole 10 means that the U-shaped opening is directly opposite the placement hole 10, and the adjustment bracket 20 is arranged symmetrically along the axis of the placement hole 10.

[0043] A first gripper 23 is provided inside the adjusting frame 20, facing the placement hole 10. A first guide unit is provided between the first gripper 23 and the adjusting frame 20, and the guiding direction is perpendicular to the axis of the placement hole 10. Specifically, the first guide unit includes a guide groove 220 and a guide block 221. The guide groove 220 is recessed on both sides of the inner wall of the adjusting frame 20, forming a guiding engagement with the guide block 221 protruding on both sides of the first gripper 23. In fact, the guide groove 220 and the guide block 221 mainly serve a guiding function. Alternatively, depending on the actual processing difficulty and requirements, another guide block 221 can be provided on both sides of the inner wall of the adjusting frame 20, which guides and engages with the guide groove 220 recessed on both sides of the first gripper 23.

[0044] The adjustment unit is configured to adjust the first gripper 23 to move along the guide direction. Specifically, the adjustment unit includes a handle 210, a screw 211 and a screw hole 212. The end face of the adjustment bracket 20 away from the placement hole 10 passes through the screw hole 212. The screw hole 212 engages with the screw 211, and one end of the screw 211 is interchangeably engaged with the surface of the first gripper 23.

[0045] It is worth mentioning that the surface of the first gripper 23 facing the placement hole 10 is preferably a concave arc surface, and the curvature of the arc surface is preferably consistent with the curvature of the surface of the wheel piece to be processed. Since the side of the existing wheel piece to be processed is basically concave, forming a cross-sectional structure similar to an I-shape, the arc surface is preferably chamfered. On the one hand, this can ensure that the first gripper 23 fits the surface of the wheel piece to be processed to the greatest extent; on the other hand, it reduces obstruction when the first gripper 23 is inserted into the side of the wheel piece to be processed.

[0046] See Figure 3 A tray assembly is installed inside the placement hole 10. The tray assembly includes an upper tray 30, a lower tray 31 and a connecting plate 32. The lower tray 31 is coaxially arranged below the upper tray 30. The diameter of the lower tray 31 is larger than that of the upper tray 30, and they are fixed together by the connecting plate 32 to form a barrel-shaped structure. Considering the heat dissipation requirements, the connecting plate 32 is preferably two pieces, and a gap is reserved between them.

[0047] See Figure 4The upper tray 30 has a through-hole 301 in the middle. A second clamping assembly is provided at the lower opening of the through-hole 301. The second clamping assembly is used to clamp the wheel axle. Specifically, the second clamping assembly includes a second power unit 40, a second gripper 41, and a third gripper 42. Specifically, the third gripper 42 is provided on the lower surface of the upper tray 30 and is located on one side of the lower opening of the through-hole 301. The through-hole 301 has a square hole structure. The second gripper 41 is provided on the other side of the lower opening of the through-hole 301. The second gripper 41 and the third gripper 42 are arranged opposite to each other. The third gripper 42 and the second gripper 41 are preferably constructed of V-shaped blocks with their V-shaped openings facing each other, forming a clamping space. The third gripper 42 is driven by the second power unit 40 to move closer to or away from the second gripper 41, and the direction of movement is perpendicular to the depth of the through-hole 301. The second power unit 40 is preferably a cylinder.

[0048] To ensure that the second clamping assembly can stably clamp axles of different shapes and sizes, a second clamping claw 41 mounting base is inserted into the insertion hole 301. The second clamping claw 41 is located on one side below the second clamping claw 41 mounting base. Therefore, the second clamping claw 41 is still located on one side of the insertion hole 301. After insertion, the second clamping claw 41 mounting base and the insertion hole 301 are fixed to each other by bolts.

[0049] The adjustment process of the second gripper 41 is as follows: move the mounting base of the second gripper 41 along the insertion hole 301, adjust the position between the second gripper 41 and the wheel axle, and after adjustment, fix the mounting base of the second gripper 41 in the upper tray 30 with bolts.

[0050] The drive assembly is configured to drive the tray assembly to move linearly relative to the first clamping assembly along the depth direction of the insertion hole 301. Specifically, the drive assembly includes a third guide unit and a third power unit 51. The third power unit 51 is preferably an electric hydraulic cylinder. The lower tray 31 is provided with a fixed end of the third power unit 51, and the output end of the third power unit 51 is connected to the bottom of the placement hole 10.

[0051] A third guide unit is provided inside the placement hole 10. The third guide unit and the lower tray 31 form a guide engagement along the depth direction of the insertion hole 301. Specifically, a base 6 is provided at the bottom of the placement hole 10, and a guide shaft 502 is provided on the base 6. Preferably, there are four guide shafts 502, which are arranged in a circular array along the axis of the placement hole 10 to ensure uniform force distribution. The axis of the guide shaft 502 is parallel to the axis of the placement hole 10. The guide shaft 502 is engaged with the corresponding sliding sleeve 501 provided on the lower tray 31. The guide shaft 502 is offset from the upper tray 30.

[0052] The process of removing the axle from the wheel piece using this wheel piece removal mechanism is as follows:

[0053] S1. Place several wheel pieces on the upper tray 30;

[0054] S2. Adjust the first clamping assembly, twist the handle 210 so that the screw 211 engages with the screw hole 212, and drive the first gripper 23 to move until it is locked on both sides of the wheel piece to be processed.

[0055] S3. Start the second clamping assembly, drive the second power unit 40, and move the second gripper 41 to be close to the wheel axle. The second gripper 41 and the third gripper 42 are close to both sides of the wheel axle to fix the wheel axle.

[0056] S4. Start the drive assembly. The third power unit 51 drives the wheel at the bottom of the wheel to be processed and the wheel shaft to move downward until the wheel shaft is disengaged from the wheel to be processed. The wheel to be processed is in the starting position, which is convenient for the next step.

[0057] This invention uses a first clamping assembly and a second clamping assembly to fix the axle and the wheel piece to be processed, respectively. A drive assembly drives the axle and other wheel pieces to descend, thereby separating the axle, other wheel pieces, and the wheel piece to be processed. This allows the wheel pieces to be removed from the axle sequentially and quickly, replacing the inconvenience and complexity caused by manual operation. In addition, the second clamping assembly can align the wheel piece to be processed, ensuring that the wheel piece to be processed is always in the initial position, which is convenient for the robot to place and pick up, and facilitates the operation of the entire process.

[0058] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
