Description

Technical Field

[0001] The utility model relates to the technical field of automobile repair tools, and particularly relates to a safe and labor-saving brake drum disassembly and assembly device. Background Technique

[0002] Long-term driving of an automobile will cause the tire lining to adhere to the wheel hub and the brake drum to adhere to the axle directly, affecting the normal driving of the automobile. During maintenance, it is necessary to disassemble and assemble the tire and the wheel hub, as well as the brake drum and the axle. In the prior art, most maintenance personnel use a multi-person cooperation method and rely on tools such as pry bars and sledgehammers to disassemble the brake drum. However, in this disassembly method, tools such as pry bars and sledgehammers will damage relevant parts such as the brake drum. Moreover, in actual operation, using the above tools to disassemble and assemble the tire brake drum is not only time-consuming and laborious, with low work efficiency, but also has obvious safety hazards of mechanical injury, which is not conducive to practical application. For this reason, we have proposed a safe and labor-saving brake drum disassembly and assembly device. Content of the Utility Model

Specific implementation mode

[0019] The following combines the drawings and embodiments to further describe the specific implementation mode of the present utility model. The following embodiments are only used to more clearly illustrate the technical solution of the present utility model, and cannot be used to limit the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , the present utility model provides a technical solution: a safe and labor-saving brake drum disassembly and assembly device, including a moving frame 1 with universal wheels 2 installed at the four corners of the bottom. The universal wheels 2 are universal wheels with brakes. A mounting frame 4 is fixed at the top of the moving frame 1. The mounting frame 4 is a C-shaped groove with an opening facing the inside of the moving frame 1. One end of the top of the mounting frame 4 is fixed with a push rod 3. A jack 5 is horizontally installed in the mounting frame 4. The stroke end of the jack 5 is connected with a limit plate 6. Buffer springs 7 are connected between both sides of the limit plate 6 and the mounting frame 4. The buffer springs 7 are used to buffer the pressure of the jack 5. Towing arms 8 are movably arranged on both sides of the mounting frame 4 close to the limit plate 6;

[0021] Furthermore, one end of the towing arm 8 is fixed with a first rotating shaft 9 connected to the mounting frame 4. The top of the first rotating shaft 9 is connected to the mounting frame 4 through a locking nut 10; by rotating the towing arm 8, the end of the towing arm 8 away from the moving frame 1 hooks the brake drum, and then by tightening the locking nut 10, the first rotating shaft 9 is locked with the top of the mounting frame 4, so that the towing arm 8 is locked with the mounting frame 4, preventing the towing arm 8 from moving during work and improving stability;

[0022] Specifically, by setting the jack 5, the limit plate 6 and the towing arm 8, using the jack 5 to push out the limit plate 6 so that it abuts against the end face of the brake drum, and then cooperating with the towing arm 8 to hook the brake drum, and then using an air gun to turn the brake drum, the brake drum can be disassembled. Compared with the prior art, there is no need to use a pry bar and a sledgehammer, which not only saves time and effort, improves work efficiency, but also effectively avoids damage to the brake drum by tools, which is beneficial to practical application.

[0023] A receiving plate 11 is slidably arranged at the inner bottom of the moving frame 1; both sides of the receiving plate 11 are provided with sliders, and sliding grooves matching the sliders are provided on the inner walls of both sides of the bottom of the moving frame 1 to facilitate the sliding of the receiving plate 11;

[0024] Furthermore, limiting blocks 12 are symmetrically and fixedly arranged at the top of the receiving tray 11; as Figure 1 shown, the limiting blocks 12 are arranged in a triangular structure so as to limit the cylindrical brake pot and prevent the brake pot from detaching from the receiving tray 11;

[0025] One end of the receiving tray 11 away from the moving frame 1 is connected with a detachable support mechanism at the bottom;

[0026] Furthermore, the support mechanism includes a horizontally arranged support frame 13, and a triangular support member 14 connected to the receiving tray 11 is arranged on the support frame 13;

[0027] Specifically, since only one end of the above-mentioned receiving tray 11 has support and the other end has no support, when the brake pot falls onto the receiving tray 11, a large pressure will be exerted on the receiving tray 11, which is likely to cause the receiving tray 11 to tip over. By using the support mechanism, the receiving tray 11 stands on the ground and the other end is effectively supported;

[0028] Furthermore, the support frame 13 includes a first assembly rod 131 and a second assembly rod 132. Magnetic attraction blocks 133 are fixed at both ends of the first assembly rod 131, and magnetic attraction seats 134 with magnetic properties opposite to those of the magnetic attraction blocks 133 are fixed at both ends of the second assembly rod 132; magnetic coating layers with opposite magnetic properties are respectively coated on the surfaces of the magnetic attraction blocks 133 and the inner walls of the magnetic attraction seats 134. By using the magnetic attraction force, the first assembly rod 131 and the second assembly rod 132 can be stably spliced with each other, so that the support frame 13 is formed;

[0029] Furthermore, the triangular support member 14 includes a support rod 141 whose top end is connected by a second rotating shaft 142. Limiting rings 143 are sleeved at both ends of the second rotating shaft 142, and magnetic attraction blocks 144 are fixed at both ends of the second rotating shaft 142. A fixing plate 15 is arranged at the bottom of the receiving tray 11, and a magnetic attraction seat 16 with magnetic properties opposite to those of the magnetic attraction blocks 144 is fixed on the fixing plate 15. Magnetic coating layers with opposite magnetic properties are respectively coated on the surfaces of the magnetic attraction blocks 144 and the inner walls of the magnetic attraction seats 16. By using the magnetic attraction force, the fixing plate 15 and the triangular support member 14 are stably assembled. A magnetic attraction block 145 is fixed at the bottom end of the support rod 141, and magnetic attraction seats 17 with magnetic properties opposite to those of the magnetic attraction blocks 145 are fixed at both ends of the bottom of the second assembly rod 132. Magnetic coating layers with opposite magnetic properties are respectively coated on the surfaces of the magnetic attraction blocks 145 and the inner walls of the magnetic attraction seats 17. By using the magnetic attraction force, the triangular support member 14 and the support frame 13 can be stably connected, which is convenient for both the assembly and disassembly of the support mechanism;

[0030] Specifically, by setting the receiving tray 11, the support frame 13 and the triangular support member 14, before disassembling the brake drum, the receiving tray 11 is pulled out from the moving frame 1 to receive the disassembled brake drum. In cooperation with the support frame 13 and the triangular support member 14, the bottom of the receiving tray 11 is supported to prevent the receiving tray 11 from being tilted due to force and affecting its stability, which is convenient to use.

[0031] Furthermore, a tool box 18 is provided at the bottom of the moving frame 1. Convex strips 19 are provided on both sides of the tool box 18, and a moving groove 20 cooperating with the convex strips 19 is fixed at the bottom of the moving frame 1.

[0032] Specifically, by setting the tool box 18 for storing maintenance tools, the support frame 13 and the triangular support member 14, not only space is saved, but also it is convenient for subsequent use.

[0033] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
