Description

Technical Field

[0001] The utility model relates to a disassembly tool, in particular to a tool for disassembling fan blades in a shoe-making grinding wheel machine. Background Art

[0002] The shoemaking grinding machine has the functions of grinding, raising, trimming and polishing. In actual shoemaking production, workers can complete different shoemaking production tasks by replacing grinding wheels, sanding belt wheels or brush wheels. It is widely used in shoemaking production lines due to its diverse functions, high degree of automation and high production efficiency.

[0003] An existing shoemaking grinding machine usually includes a grinding machine body, a driving mechanism fixedly mounted on the grinding machine body, a rotating shaft rotatably mounted on the grinding machine body and fixedly connected to the power output end of the driving mechanism, a grinding wheel fixedly mounted on the rotating shaft, and a dust suction fan fixedly mounted on the grinding machine body, wherein the dust suction fan can absorb a large amount of dust generated by the shoemaking grinding machine when grinding shoes, thereby effectively reducing dust pollution in the production workshop.

[0004] After the shoemaking grinder has been used for a long time, a large amount of dust and dirt will adhere to the blades in the dust suction fan, which will affect the dust suction effect of the dust suction fan. For this reason, in actual production, workers need to clean the blades regularly. When cleaning the blades, it is necessary to first remove the blades in the shoemaking grinder and then clean them. The blades in the current dust suction fan include a blade body and a sleeve fixed on the blade body and used to be plugged into the fan shaft in the dust suction fan, wherein the fan shaft and the sleeve in the dust suction fan are interference fit, which makes it difficult for workers to remove the blades. The process of removing the blades is laborious and time-consuming, which will result in high work intensity for workers and low efficiency of disassembly work. Summary of the invention

[0005] In order to solve the above deficiencies in the prior art, the utility model aims to provide a tool for disassembling fan blades in a shoemaking grinding machine, so as to reduce the work intensity of workers and improve the disassembly efficiency of workers.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is as follows: a tool for disassembling the fan blades in a shoemaking grinding machine, comprising a connecting mechanism for threaded connection with the shaft sleeve of the fan blades in the shoemaking grinding machine, a threaded rod threadedly connected to the connecting mechanism and extending to the outside of the connecting mechanism, and a rotating handle fixed to the top of the threaded rod.

[0007] As a definition of the present utility model, the connecting mechanism includes a first connecting block and a second connecting block fixed on the top of the first connecting block; a circular groove is provided at the bottom of the first connecting block, and an internal thread is provided on the circular groove that matches the external thread on the outer surface of the sleeve so that the first connecting block can be threadedly connected to the sleeve; the threaded rod is threadedly connected to the second connecting block and extends into the circular groove.

[0008] As a further limitation of the present invention, a clamping member for clamping a fan shaft in a shoemaking grinder is fixedly disposed on one end of the threaded rod away from the rotating handle.

[0009] As another limitation of the present invention, the rotating handle includes a mounting seat fixedly mounted on the top of the threaded rod and an operating rod horizontally slidably connected to the mounting seat.

[0010] As a further limitation of the present invention, a non-slip rubber layer is fixedly provided on the operating rod.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0012] (1) The utility model is provided with a connecting mechanism, a threaded rod and a rotating handle. When in use, the connecting mechanism is threadedly connected to the shaft sleeve of the fan blade in the shoemaking grinder. The rotating handle can be rotated to move the threaded rod in the direction of the fan shaft and press against the front end of the fan shaft. Then, the rotating handle is continuously rotated, and the front end of the fan shaft will generate an outward force on the shaft sleeve in the fan blade. At this time, the fan blade can be easily disassembled. The process of disassembling the fan blade is both time-saving and labor-saving, which can effectively reduce the work intensity of workers and improve the disassembly efficiency of workers.

[0013] (2) The utility model has a simple structure and low manufacturing cost. By providing a circular groove and an internal thread on the first connecting block, the first connecting block and the shaft sleeve can be easily fixedly connected together, which can effectively improve the convenience of operation of the utility model. In addition, the provision of the second connecting block in the utility model can increase the threaded connection length between the threaded rod and the connecting mechanism, so that the threaded rod can be more stably threadedly connected to the connecting mechanism, which can effectively improve the stability of the utility model when in use.

[0014] (3) The utility model is provided with a clamping member, which can more firmly clamp the fan shaft in the shoemaking grinder to ensure the stability of the use of the utility model.

[0015] (4) The rotating handle of the utility model adopts a structural form that combines a mounting base and an operating rod, wherein the operating rod is horizontally slidably connected to the mounting base. When in use, the length of one end of the handheld operating rod extending out of the mounting base can be adaptively adjusted as needed to adjust the size of the power arm. Even if the worker has less strength, the fan blades can be easily removed by using the utility model. The utility model is suitable for workers with different strengths, which effectively improves the convenience and practicality of operation of the utility model.

[0016] (5) The utility model is provided with an anti-skid rubber layer, which can enhance the friction between the human hand and the operating rod when in use, allowing the human hand to operate the rotating handle more stably. In addition, the material of the anti-skid rubber layer is relatively soft, which can also improve the comfort of using the utility model.

[0017] In summary, the utility model has a simple structure, low manufacturing cost and strong practicality. The fan blades in the shoemaking grinder can be easily disassembled by using the utility model. The process of disassembling the fan blades is both time-saving and labor-saving, which can effectively reduce the work intensity of workers and improve the disassembly efficiency of workers. The utility model is suitable for use when disassembling the fan blades in the shoemaking grinder. BRIEF DESCRIPTION OF THE DRAWINGS
