Description

Technical Field

[0001] The invention relates to the technical field of grinders, in particular to an abrasive belt grinding head used on a lathe. Background Art

[0002] Abrasive belt is a belt-shaped tool that can be used for grinding and polishing. It is made by bonding abrasives to flexible materials such as paper and cloth with a binder. It is a major form of coated abrasives. Its basic components are: substrate, abrasive and binder, collectively known as the three elements of abrasive belt. After nearly 30 years of development, abrasive belt grinding has become a relatively complete and self-contained new processing technology. It is deeply loved by users for its high processing efficiency, wide application range, strong adaptability, low cost of use, safe and convenient operation, etc.

[0003] At present, most of the grinding methods for many shaft parts on the market are still turning or grinding with a grinding wheel. The rigid impact during the grinding process is large, while the chip force is relatively small, which creates a large safety hazard during the grinding process. At the same time, it reduces the grinding utilization rate and consumes a lot of energy, which is not conducive to saving resources and protecting the environment. Summary of the invention

[0004] The purpose of the present invention is to provide a belt grinding head for use on a lathe to solve the problem that the rigid impact during the grinding process is large, while the chip force is relatively small, which creates a large safety hazard during the grinding process, while reducing the grinding utilization rate, consuming a lot of energy, and is not conducive to saving resources and environmental protection technology.

[0005] The purpose of the present invention can be achieved through the following technical solutions:

[0006] A belt grinding head used on a lathe, comprising:

[0007] A mounting seat, on which a driving motor is fixedly mounted;

[0008] The grinding mechanism comprises a transmission wheel, the transmission wheel and the output shaft of the driving motor are connected by a belt transmission, one end of the transmission wheel passes through the guide frame on the mounting seat and extends to the driving wheel, the driving wheel, the tensioning wheel and the transition wheel are arranged in a triangular shape and connected by a sanding belt transmission, and the transmission angle between the three is not less than 120°;

[0009] The tensioning adjustment component includes a rotating shaft placed on a mounting seat, one end of the rotating shaft is connected to a tensioning wheel through an adjustment component, and the other end is provided with a movable locking plate connected to the mounting seat, the bottom of the movable locking plate is provided with an interference portion placed on the rotating shaft, and the bottom edge of the rotating shaft is provided with a retaining ring placed on the mounting seat, and the retaining ring is provided with an arc groove adapted to the rotating shaft.

[0010] Furthermore, the deviation adjustment component includes a pushing cylinder placed between the tensioning wheel and the rotating shaft, the pushing cylinder is equipped with a frame placed on the tensioning wheel through a panel, the tensioning wheel is connected with a rotating groove near both ends of the frame, a pad connected to the panel is movably installed at the bottom of the frame, the panel and the frame are locked and fixed by an adjusting bolt, and the adjusting bolt is placed on both sides of the panel and passes through the panel to limit the contact with the frame.

[0011] Furthermore, it also includes a protective component connected to the mounting seat, the protective component includes a cover body placed outside the mounting seat, both ends of the outer wall of the cover body are provided with movable grooves placed on the driving wheel and the transition wheel, and one end of the cover body is provided with an annular opening connected to the transmission wheel, and the other end is connected to a door panel assembly.

[0012] Furthermore, the door panel assembly includes a first baffle placed at both ends of the outer wall of the cover body and hinged to the hinge, a second baffle is provided on the first baffle and hinged to the hinge, movable buckles are installed on the first baffle and the second baffle, one end of the movable buckle is connected to a fixing plate adapted thereto, and an arc-shaped bayonet is connected to one end of the fixing plate near the movable buckle.

[0013] Furthermore, the cover body is formed by welding steel plates.

[0014] Furthermore, a limiting plate connected to the mounting seat is provided at the bottom of the driving motor.

[0015] The beneficial effects of the present invention are as follows:

[0016] (1) The abrasive belt used in belt grinding is lighter than the grinding wheel used in wheel grinding, and the vibration caused by rotation is smaller. The grinding head can be installed on the lathe and used in combination with the turning tool, or it can be used alone. When used alone, it is similar to the external cylindrical grinding. By changing the mesh number of the abrasive belt, the required roughness can be achieved. The grinding head can be used for water grinding or dry grinding, which is more flexible to use.

[0017] (2) The linear speed of belt grinding is stable. The diameter of the grinding wheel becomes smaller after use, and the linear speed of the grinding wheel will change, which is easy to cause color difference. Belt grinding has stronger cutting force than grinding wheel, and the grinding ratio is much higher than that of grinding wheel grinding. Therefore, the utilization rate of belt grinding is more energy-saving than that of grinding wheel grinding.

[0018] (3) The belt transmission mechanism of the present invention has a tension adjustment component and a deviation adjustment component, which can effectively prevent the position deviation of the belt during the transmission process, and at the same time can adjust the tension of the belt to a certain extent, thereby ensuring the stability of the belt grinding operation.
