Description

Technical Field

[0001] This application relates to the field of automotive technology, and in particular to a clutch motor compression spring assembly tool. Background Technology

[0002] In the assembly of clutch motors, the installation of the compression spring assembly is a critical and challenging step. This spring assembly has a significant preload in its free state, requiring considerable elastic resistance to overcome during installation. Traditional assembly methods rely entirely on manual stretching of the spring while simultaneously fastening the fasteners. This approach presents several problems: First, manual operation is extremely physically demanding, resulting in low assembly efficiency; second, performing precise tightening while forcefully stretching the spring easily leads to slippage or misalignment, causing damage to parts; third, the sudden release of the spring while stretched can cause safety accidents. Currently, the industry lacks specialized assembly tools, resulting in multiple problems in the production process, including high labor intensity, inconsistent assembly quality, and significant safety hazards. Utility Model Content

[0003] To address the aforementioned problems, this application provides a clutch motor compression spring assembly tool. Through the design of this specialized assembly tool, rapid, safe, and reliable assembly of the spring assembly is achieved, significantly improving assembly efficiency, reducing operational difficulty, and avoiding the risk of component damage. The tool possesses both installation and disassembly functions, exhibiting excellent practicality and economy. The technical solution is as follows: This application provides a clutch motor compression spring assembly tool, including an operating handle and an operating head. The operating head is disposed at one end of the operating handle. The operating head includes a positioning part and a clamping part. The positioning part has a blind hole for fitting onto a hexagonal bolt at the end of the spring assembly. The clamping part has an arc-shaped limiting structure for limiting the spring guide post at the end of the spring assembly. The clamping part is configured to complete the spring installation by counterclockwise rotation and to complete the spring removal by clockwise rotation.

[0004] For example, in one embodiment of the clutch motor compression spring assembly tool, the inner wall of the clamping part is provided with a left-hand guide groove and a right-hand guide groove; a bolt slot communicating with the blind hole is formed between the left-hand guide groove and the right-hand guide groove.

[0005] For example, in the clutch motor compression spring assembly tool provided in one embodiment, the left-hand guide groove includes a first arc-shaped groove surface and a second arc-shaped groove surface; the right-hand guide groove includes a third arc-shaped groove surface.

[0006] For example, in one embodiment of the clutch motor compression spring assembly tool, the axial length of the left-hand guide groove is greater than the axial length of the right-hand guide groove.

[0007] For example, in one embodiment of the clutch motor compression spring assembly tool, a stepped transition surface is provided at the connection between the right-hand guide groove and the bolt slot.

[0008] For example, in one embodiment of the clutch motor compression spring assembly tool, the operating handle and the operating head are integrally formed.

[0009] For example, in one embodiment of the clutch motor compression spring assembly tool, the operating handle and the operating head are detachably connected.

[0010] For example, in one embodiment of the clutch motor compression spring assembly tool, the curvature of the arc-shaped limiting structure is adapted to the outer peripheral surface of the spring guide post.

Obviously, the drawings described below are only some embodiments of this application. For those skilled in the art, other drawings can be obtained based on these drawings without creative effort.

Figure 4 This is a schematic diagram of the clutch motor compression spring assembly tool of this application from another angle in its usage state. Detailed Implementation

[0015] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0016] like Figure 1 As shown, in the clutch motor, one end of the spring assembly 300 is connected to the swing arm 600 through the pin assembly 500, and the other end is provided with a spring guide post 320. A hexagonal bolt 310 is inserted in the center of the spring guide post 320. The spring end is fixedly installed on the clutch motor mounting plate 400 by the hexagonal bolt 310. The rotation of the swing arm 600 drives the spring to stretch. When the swing arm swings to the farthest point, the spring is stretched to its longest point. The spring also has a large elastic force when it is in its longest state. It is difficult to manually install the spring assembly 300.

[0017] In view of this, this application provides a clutch motor compression spring assembly tool, such as Figure 2-3 As shown, the device includes an operating handle 100 and an operating head 200 for fixing one end of the spring assembly 300 to the clutch motor mounting plate 400. The operating head 200 is disposed at one end of the operating handle 100. The operating head 200 includes a positioning part 210 and a clamping part 220. The positioning part 210 has a blind hole 211 for fitting onto the hexagonal bolt 310 at the end of the spring assembly 300. The clamping part 220 has an arc-shaped limiting structure for limiting the spring guide post 320 at the end of the spring assembly 300. The clamping part 220 is configured to complete the spring installation by counterclockwise rotation and the spring removal by clockwise rotation.

[0018] The positioning part 210 is provided with a blind hole 211 and can be fitted onto the hexagonal bolt 310, which provides a basis for axial positioning and torque transmission of the fastener, ensuring the effective performance of the tightening operation.

[0019] Since the clamping part 220 is provided with an arc-shaped limiting structure and can limit the spring guide post 320, it provides radial clamping and positioning of the end of the spring assembly 300, preventing it from shaking or coming out during operation.

[0020] Since the clamping part 220 is configured to complete installation / removal by counterclockwise / clockwise rotation, it integrates the dual functions of installation and removal into a single tool. With a clear definition of rotation direction, the operation process is intuitive and reliable, solving the problem of difficult disassembly in traditional methods.

[0021] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 3As shown, the inner wall of the clamping part 220 is provided with a left-hand guide groove 221 and a right-hand guide groove 222; a bolt groove 223 communicating with the blind hole 211 is formed between the left-hand guide groove 221 and the right-hand guide groove 222.

[0022] According to the above embodiments, since the left-hand guide groove 221, the right-hand guide groove 222, and the bolt slot 223 are provided, optimized force transmission paths are provided for operations with different rotation directions. Furthermore, the bolt slot 223 can limit the hexagonal bolt 310 column body in the early stage of operation, assisting the bolt head to smoothly enter the blind hole 211, thereby improving the smoothness and fault tolerance of the operation.

[0023] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 3 As shown, the left-hand guide groove 221 includes a first arc-shaped groove surface S1 and a second arc-shaped groove surface S2; the right-hand guide groove 222 includes a third arc-shaped groove surface S3.

[0024] According to the above embodiments, since the left-hand guide groove 221 adopts the first and second arc-shaped groove surfaces and the right-hand guide groove 222 adopts the third arc-shaped groove surface, the contact area with the spring guide post 320 is increased by combining multiple arc surfaces, making the force more uniform and avoiding stress concentration. At the same time, it can provide more continuous and stable guidance and support during the twisting process.

[0025] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 3 As shown, the axial length of the left-hand guide groove 221 is greater than the axial length of the right-hand guide groove 222.

[0026] According to the above embodiment, since the axial length of the left-hand guide groove 221 is greater than that of the right-hand guide groove 222, it provides a longer guide and support surface for installation operations (which typically require greater stroke and more stable guidance), while for disassembly operations, the shorter guide groove is sufficient to meet its needs. This differentiated design optimizes the structure and function of the tool.

[0027] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 3 As shown, a stepped transition surface 224 is provided at the connection between the right-hand guide groove 222 and the bolt slot 223.

[0028] According to the above embodiment, since a stepped transition surface 224 is provided at the connection between the right-hand guide groove 222 and the bolt slot 223, when disassembling by turning clockwise, the stepped transition surface 224 can interact with the end of the spring guide post 320 to generate an upward pushing force. This component force helps to overcome the initial static friction of the thread and assists the hexagonal bolt 310 to be smoothly unscrewed from the mounting hole, greatly simplifying the disassembly process.

[0029] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 2-3 As shown, the operating handle 100 and the operating head 200 adopt an integral molding structure.

[0030] According to the above embodiments, the use of a one-piece molded structure eliminates the connection interface, improves the overall rigidity and strength of the tool, and enables it to withstand repeated torsional loads without being easily damaged or deformed.

[0031] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 2-3 As shown, the operating handle 100 and the operating head 200 adopt a detachable connection structure.

[0032] According to the above embodiments, due to the adoption of a detachable connection structure, the operating head or operating handle can be replaced individually according to different assembly scenarios or damage conditions, thereby improving the flexibility, economy and maintainability of the tool.

[0033] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 4 As shown, the arc of the arc-shaped limiting structure is adapted to the outer peripheral surface of the spring guide post 320.

[0034] According to the above embodiments, since the arc of the arc-shaped limiting structure is adapted to the outer peripheral surface of the spring guide post 320, surface contact or near-surface contact is achieved, which increases the friction and reduces the contact stress, effectively prevents slippage during operation, protects the surface of the parts, and ensures efficient torque transmission.

[0035] For example, in one embodiment of the clutch motor compression spring assembly tool, such as Figure 4 As shown, the dimensions of the blind hole 211 match the end dimensions of the hexagonal bolt 310.

[0036] According to the above embodiment, since the size of the blind hole 211 matches the end of the hexagonal bolt 310, it ensures that there is an appropriate fitting clearance between the bolt head and the inner wall of the blind hole, so that it can be smoothly inserted and provide sufficient contact surface to transmit torque when screwing, avoiding stripping or damage.

[0037] The clutch motor compression spring assembly tool of this application, when in use, involves inserting the end of the hexagonal bolt 310 into the blind hole 211; allowing the spring guide post 320 to be accommodated within the arc-shaped limiting structure; and then rotating the operating handle 100 counterclockwise to screw the hexagonal bolt 310 into the mounting hole on the motor mounting plate 400, thus completing the spring installation; or, rotating the operating handle 100 clockwise to unscrew the hexagonal bolt 310 from the mounting hole, thus completing the spring disassembly. By adopting the assembly tool of this application and clarifying the steps of inserting, accommodating, and rotating clockwise / counterclockwise, complex and laborious manual operations are transformed into a standardized and mechanized process, significantly reducing the physical strength and skill requirements for operators. Simultaneously, due to the tool's excellent positioning and clamping characteristics, the consistency and reliability of assembly quality are ensured, and work efficiency is improved.

[0038] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
