[0023] As described in the background, when a coil spring clutch on a vehicle fails, the coil spring clutch assembly needs to be disassembled and reassembled. To prevent the coil spring from interfering with assembly and disassembly, the coil spring clutch assembly must be compressed before disassembly or installation.

[0024] The existing disassembly and assembly tool of the coil spring clutch assembly is a screw type. When in use, at least two people are required to hold the coil spring clutch assembly and at least two people are required to turn the nut to complete the disassembly of the coil spring clutch assembly. The process is time-consuming and labor-intensive. In addition, when reassembling the coil spring clutch assembly, it is difficult to adjust the coil spring to the specified standard value. Therefore, a coil spring clutch assembly disassembly and assembly tool is urgently needed to solve the problem of low disassembly and assembly efficiency of the coil spring clutch assembly.

[0025] The present application is described in detail below through one or more specific embodiments. A hydraulic coil spring clutch assembly disassembly tool, such as Figure 1 and Figure 2 Shown, including:

[0026] Support frame 10, including top beam 11 and middle beam 12;

[0027] Hydraulic structure 20, including connected output end 21 and input end 22, the input end 22 is located at the bottom of the side of the support frame 10, and the output end 21 is located on the top beam 11 of the support frame 10 and is arranged towards the middle beam 12;

[0028] The middle beam 12 is used to carry the spiral spring clutch assembly to be disassembled, and the output end 21 of the hydraulic structure 20 moves towards the spiral spring clutch assembly to be disassembled to press and fix the spiral spring clutch assembly to be disassembled.

[0029] Specifically, the hydraulic structure 20 is located on the support frame 10, wherein the input end 22 (i.e. hydraulic operating rod) of the hydraulic structure 20 is located at the bottom of the side of the support frame 10 so that the user operates the input end 22, and the output end 21 (i.e. hydraulic piston) of the hydraulic structure 20 is located on the top beam 11 so that the output end 21 is close to or away from the spiral spring clutch assembly to be disassembled located on the middle beam 12, thereby achieving the purpose of pressing and fixing or releasing the pressing and fixing of the spiral spring clutch assembly to be disassembled, so that the user disassembles or takes out the spiral spring clutch assembly to be disassembled which is pressed and fixed.

[0030] In addition, the top beam 11 includes two U-shaped beams of the same specification, the output end 21 of the hydraulic structure 20 is located between the two U-shaped beams and is arranged through the top beam 11, or the top beam 11 has a through hole located on the center line of the top beam 11, and the output end 21 of the hydraulic structure 20 is arranged through the through hole, and the top surface of the middle beam 12 is a planar structure to stably carry the spiral spring clutch assembly to be disassembled and is arranged corresponding to the center point of the top beam 11, so that when the output end 21 of the hydraulic structure 20 applies a pressing force to the spiral spring clutch assembly to be disassembled located on the middle beam 12, it acts on the center point of the spiral spring clutch assembly to be disassembled, which is beneficial to the uniformity of pressing the spiral spring clutch assembly to be disassembled, thereby improving the disassembling effect and practicability of the disassembling tool.

[0031] In the embodiment, the hydraulic structure 20 and the spiral spring clutch assembly to be disassembled are carried by the support frame 10, and the hydraulic structure 20 is abutted with the spiral clutch assembly to be disassembled, so as to fix the spiral clutch assembly to be disassembled, thereby facilitating the user to disassemble and assemble the spiral clutch assembly to be disassembled, and facilitating the disassembly and assembly process, improving the disassembly and assembly efficiency. The output end 21 of the hydraulic structure 20 can be adjusted in length to adapt to different types of spiral clutch assemblies to be disassembled, thereby improving the practicability of the disassembly and assembly tool.

[0032] In some embodiments, the hydraulic structure 20 further comprises a hydraulic oil cylinder 23, the input end 22 is connected with the hydraulic oil cylinder 23, the hydraulic oil cylinder 23 is connected with the output end 21 through a hydraulic oil pipe, and the output end 21 is connected with an oil pressure gauge 24.

[0033] Specifically, the input end 22 is used to control the oil input by the hydraulic oil cylinder 23 to the output end 21. After receiving the oil, the output end 21 will produce a corresponding displacement to balance the pressure balance in the hydraulic structure 20. The output end 21 is provided with the oil pressure gauge 24 to measure the pressure in the output end 21 (i.e. the pressure in the hydraulic structure 20) to determine the pressure in the hydraulic structure 20 when the output end 21 presses the spiral clutch assembly to be disassembled. Therefore, according to the value of the oil pressure gauge 24, the distance between the output end 21 of the hydraulic structure 20 and the spiral clutch assembly to be disassembled can be controlled when the spiral clutch assembly to be disassembled is assembled next time. This is beneficial to control the spiral spring in the spiral spring clutch assembly to be disassembled at the position of the spiral spring during the disassembly of the spiral spring clutch assembly to be disassembled (i.e. the specified standard value), thereby improving the assembly effect of the spiral spring clutch assembly to be disassembled.

[0034] It should be noted that when the spiral spring clutch assembly to be disassembled is disassembled, the value of the oil pressure gauge 24 is recorded. When the spiral spring clutch assembly to be disassembled is assembled subsequently, the hydraulic structure 20 is adjusted so that the value of the oil pressure gauge 24 is the same as that during disassembly. In this state, the assembly of the spiral spring clutch assembly to be disassembled is carried out. At this time, the pressing force of the output end 21 of the hydraulic structure 20 on the spiral spring clutch assembly to be disassembled is the same as that during disassembly.

[0035] In some embodiments, the disassembly and assembly tool further comprises a support disc 30 and a cover plate 40, the support disc 30 and the cover plate 40 are located at the bottom and the top of the spiral spring clutch assembly to be disassembled respectively.

[0036] Specifically, the support plate 30 is located on the middle crossbeam 12 to support the coil spring clutch assembly to be disassembled and ensure the stability of the disassembled coil spring clutch assembly on the middle crossbeam 12. The cover plate 40 is used to cover the coil spring clutch assembly to be disassembled. The support plate 30 is used to improve the stability of the coil spring clutch assembly to be disassembled. The cover plate 40 is used to press the coil spring clutch assembly to be disassembled to ensure that the output end 21 of the hydraulic structure 20 applies force evenly to the coil spring clutch assembly to be disassembled, thereby facilitating the disassembly and assembly of the coil spring clutch assembly to be disassembled.

[0037] It should be noted that when the disassembly and assembly tool is in a placed state (i.e., not in use), the support plate 30 and the cover plate 40 are separately arranged relative to the support frame 10 for easy storage. When the disassembly and assembly tool is in use, the support plate 30 is located on the middle crossbeam 12, the coil spring clutch assembly to be disassembled is located on the support plate 30, and the cover plate 40 is located on the side of the coil spring clutch assembly to be disassembled close to the output end 21.

[0038] In some embodiments, the support plate 30 and the cover plate 40 are both circular structures.

[0043] Specifically, the top crossbeam 11 and the middle crossbeam 12 are arranged up and down, the first vertical rod 13 is located on the left side of the top crossbeam 11 and the middle crossbeam 12, and is connected to the left ends of the top crossbeam 11 and the middle crossbeam 12, and the second vertical rod 14 is located on the right side of the top crossbeam 11 and the middle crossbeam 12, and is connected to the right ends of the top crossbeam 11 and the middle crossbeam 12. The first vertical rod 13 and the second vertical rod 14 play a role in supporting the top crossbeam 11 and the middle crossbeam 12.

[0044] The I-shaped base 15 includes a left support beam, a bottom cross beam and a right support beam connected in sequence, the bottom cross beam is located below the middle cross beam 12, the left support beam is located on the side of the first vertical rod 13 away from the middle cross beam 12, and is in contact with the first vertical rod 13, the right support beam is located on the side of the second vertical rod 14 away from the middle cross beam 12, and is in contact with the second vertical rod 14, the bottoms of the first vertical rod 13 and the second vertical rod 14 are both connected to the top surface of the bottom cross beam; the I-shaped base 15 is used to support the first vertical rod 13 and the second vertical rod 14, providing stable supporting force for the first vertical rod 13 and the second vertical rod 14, which is conducive to improving the stability of the support frame 10.

[0045] In some embodiments, wheels 16 are provided at the bottom of the I-shaped base 15 , and the wheels 16 have a brake structure.

[0047] In some embodiments, four wheels 16 are provided and are symmetrically arranged on the I-shaped base 15 .

[0048] Specifically, the wheels 16 are symmetrically arranged on the I-shaped base 15 so that the wheels 16 provide stable and uniform support to the support frame 10, thereby improving the practicality of the disassembly and assembly tool. The provision of four wheels 16 can enhance the supporting force of the wheels 16 in the disassembly and assembly tool, thereby ensuring the mobility of the disassembly and assembly tool while maintaining the supporting force of the disassembly and assembly tool, thereby improving the practicality of the disassembly and assembly tool.
