Description

Technical Field

[0001] The utility model relates to the technical field of polishing equipment, in particular to a polishing equipment for tool production. Background Art

[0002] Polishing refers to a processing method that uses mechanical, chemical or electrochemical effects to reduce the surface roughness of a workpiece to obtain a bright and smooth surface. It is a modification process of the workpiece surface using polishing tools and abrasive particles or other polishing media. Polishing equipment is particularly common in tool production.

[0003] The existing patent document with patent publication number CN212653135U discloses a document on a polishing device for tool production that is easy to fix. The utility model solves the problem that the existing polishing equipment has to be held by the user during grinding and polishing, and the user cannot free his hands and will be restricted, which brings unnecessary trouble to the user and is inconvenient for the user to use.

[0004] However, the above patent documents do not take into account the issues of sand belt utilization and operating efficiency of the polishing equipment. Since the sand belt will carry debris during the sand belt polishing process of the polishing equipment, the friction of the sand belt is reduced during polishing, which reduces the polishing efficiency. At the same time, the need for frequent replacement leads to low utilization. Therefore, it is necessary to propose a polishing equipment for tool production to solve the above problems.

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] The utility model provides Figures 1-4 The polishing equipment for tool production shown in the figure includes a workbench 1, a support base 15 is fixedly provided on the top of the workbench 1, and a driving wheel 17, a driven wheel 18 and a steering wheel 19 are rotatably provided on the same surface of the support base 15. A second motor 16 is fixedly provided on the other surface of the support base 15, and the driving shaft of the second motor 16 moves through the two side surfaces of the support base 15 and is fixedly connected to the driving wheel 17. The outer rings of the driving wheel 17, the driven wheel 18 and the steering wheel 19 are rotatably connected with an abrasive belt 20. When using this equipment, the second motor 16 is started to drive the driving wheel 17 to rotate. Through the cooperation of the driven wheel 18 and the steering wheel 19, the abrasive belt 20 can rotate stably to polish the tool.

[0025] Taking into account that the sanding belt 20 of the polishing equipment will carry debris during the polishing process, the friction of the sanding belt will be reduced during polishing, which reduces the polishing efficiency. At the same time, it needs to be replaced frequently, resulting in low utilization rate, which leads to the problem of low utilization rate and working efficiency of the sanding belt 20 of the existing polishing equipment. Therefore, a machine box 3 is provided in the utility model, and the machine box 3 is fixedly installed on the lower surface of the workbench 1. An electric push rod is provided in the machine box 3. The telescopic end of the electric push rod moves through the two side surfaces of the top of the machine box 3, and the top of the telescopic end is fixedly connected to a lifting rod 7. A support frame 8 is fixedly provided on the top of the lifting rod 7. The support frame 8 has a U-shaped structure. A brush rod 10 is rotatably provided between the two ends of the protrusion of the support frame 8. A first motor 9 is fixedly provided on the end of one end of the support frame 8. The driving shaft of the first motor 9 is fixedly connected to the end of the brush rod 10 through a convenient component.

[0026] Specifically, when the sanding belt 20 needs to be cleaned of debris attached thereto, the electric push rod is started to drive the support frame 8 to rise to a specified height, and then the first motor 9 is started to drive the brush rod 10 to rotate, thereby removing the debris from the sanding belt 20, and preventing the sanding belt from carrying debris, resulting in reduced friction of the sanding belt 20 during polishing, reducing polishing efficiency, and requiring frequent replacement, resulting in low utilization rate.

[0027] In order to better remove the debris on the sanding belt 20, the rotation direction of the brush rod 10 is opposite to that of the sanding belt 20. In this way, the first motor 9 can clean the sanding belt 20 with very little power.

[0028] In addition, in order to prevent the sanding belt 20 and the support frame 8 from touching each other, the distance between the two ends of the support frame 8 is greater than the width of the sanding belt 20, thereby avoiding contact between the two and improving the practicality of the equipment.

[0029] Since the brush rod 10 is a consumable item and needs to be replaced, in order to facilitate the replacement of the brush rod 10, the present invention solves this problem by installing a convenient component.

[0030] The screw threaded holes 13 on the top of the screw threaded holes 14 are connected to the support frame 8, and the screw threaded holes 13 on the top of the screw threaded holes 14 are connected to the support frame 8.

[0031] Taking into account that debris will be ejected when the brush rod 10 hangs out or the sanding belt 20 is processed, if it is not handled, it will pollute the working environment and endanger the health of the workers. Therefore, the utility model is provided with a rectangular opening on the workbench 1, and a collection box 2 fixedly connected to the workbench 1 is provided at the bottom of the rectangular opening. The rectangular opening and the interior of the collection box 2 are communicated with each other, and the collection box 2 and the chassis 3 are fixedly connected to each other.

[0032] Specifically, when debris flies, it can be shot into the collection box 2 through the rectangular opening for collection, thereby preventing the flying debris from polluting the working environment and endangering the health of the workers, thereby improving the practicality of the equipment.

[0033] In addition, when processing relatively corroded cutting tools, dust and rust smell are easily entrained in the debris. Therefore, a vacuum cleaner 4 is fixedly installed on the outer wall of the collection box 2, and a window is provided on the side where the collection box 2 and the vacuum cleaner 4 are close to each other. The window and the interior of the vacuum cleaner 4 are interconnected, and a filter 6 is provided in the window. After starting the vacuum cleaner 4, a negative pressure is formed inside the collection box 2, forcing the dust and rust smell to flow into the collection box 2 to avoid diffusion, thereby improving the applicability of the equipment.

[0034] The collected debris and dust need to be taken out and processed regularly. In order to facilitate removal, a drawer 5 is slidably provided at the bottom of the collection box 2. The top height of the drawer 5 is the same as the bottom height of the filter 6. The filter 6 blocks the debris and dust and makes them fall into the drawer 5. When the collected debris and dust need to be processed, just pull out the drawer 5 from the collection box 2.
