[0003] Although there are many fine grinding mechanisms on the market nowadays, these devices will become unstable after long-term use. At this time, the equipment needs to be shut down and disassembled, which reduces the working efficiency of the equipment, is time-consuming and labor-intensive, and is not convenient. At the same time, due to the high surface temperature of the fine grinding disc due to long-term work, it may affect the processed parts. In order to solve the above problems, an adjustable fine grinding mechanism is urgently needed to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to solve the problem that although there are many fine grinding mechanisms on the market nowadays, these devices will become unstable during fine grinding after long-term use, and the equipment needs to be stopped and disassembled, which reduces the working efficiency of the equipment, is time-consuming and labor-intensive, and is not convenient. At the same time, due to the high surface temperature of the fine grinding disc after long-term work, it may affect the problem of processed parts, and an adjustable fine grinding mechanism is proposed.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: an adjustable fine grinding mechanism, including a mounting base, a fixing rod is fixedly installed on the top of the mounting base, the top of the fixing rod is rotatably connected to a threaded rod, a driving ring is fixedly installed on the outer wall of the threaded rod, a limiting rod is fixedly installed on the top surface of the mounting base, a box is slidably connected to the outer wall of the limiting rod, a motor is fixedly installed on one side surface of the box, a driving adjustment component is arranged on the top of the box, and a fine grinding heat dissipation component is arranged inside the box.

[0006] As a further description of the above technical solution:

[0007] The driving and adjusting assembly comprises a second rotating wheel, one end of the output shaft of the motor is fixedly mounted with the second rotating wheel, a belt is slidably connected to the outer wall of the second rotating wheel, and the other end of the belt is slidably connected to the first rotating wheel.

[0008] As a further description of the above technical solution:

[0009] A limit frame is fixedly installed on the top surface of the box body, and the limit frame is threadedly connected to bolts through threaded holes set inside the limit frame. A sliding frame is slidably connected to the inner wall of the limit frame, and the sliding frame is threadedly connected to bolts through threaded holes set inside the limit frame. The top of the sliding frame is rotatably connected to a third rotating wheel.

[0010] As a further description of the above technical solution:

[0011] The fine grinding and heat dissipation assembly includes a mounting longitudinal rod, the bottom end of the first rotating wheel is fixedly mounted with the mounting longitudinal rod, the outer wall of the mounting longitudinal rod is fixedly mounted with a first gear, and the bottom end of the mounting longitudinal rod is fixedly mounted with a fine grinding disc.

[0012] As a further description of the above technical solution:

[0013] A rotating rod is rotatably connected to the inner wall of the top surface of the box body, a second gear is fixedly installed on the outer wall of the rotating rod, a fan is fixedly installed at the bottom end of the rotating rod, and a fan housing is fixedly installed on the bottom surface of the box body.

[0014] As a further description of the above technical solution:

[0015] A dust box is fixedly installed inside the box body, a protective cover is fixedly installed on the top of the dust box, a placement plate is fixedly installed on the bottom inner wall of the protective cover, and the first gear and the second gear are meshed and connected with each other.

[0016] In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

[0017] 1. In the utility model, a driving adjustment component and a fine grinding heat dissipation component are provided. When the device is used, the parts to be finely ground are placed on the placement plate, and then the driving ring is rotated. The rotation of the driving ring causes the threaded rod to start rotating. At this time, the box body and the fine grinding plate start to move downward until the fine grinding plate can finely grind the circular parts. The driving ring is stopped and the motor is started. The motor drives the second rotating wheel to rotate. The rotation of the second rotating wheel causes the belt to start moving. The movement of the belt causes the first rotating wheel to rotate. The rotation of the first rotating wheel drives the rotation of the installation longitudinal rod. The rotation of the installation longitudinal rod drives the rotation of the fine grinding plate and fine grinds the parts. Since the rotation of the installation longitudinal rod causes the first gear to start rotating, the second gear rotates accordingly. The rotation of the second gear causes the rotation of the rotating rod. The rotation of the rotating rod causes the fan to start rotating, and dissipates heat and cools down the fine grinding disc and parts. After the equipment has been operating for a long time, the belt will be loose. At this time, the sliding frame is moved to make the outer wall of the third rotating wheel stick to the belt to keep the belt taut. Then the bolt is rotated to keep the sliding frame fixed. Through this design, not only the function of adjusting the fine grinding mechanism is realized, but also the fine grinding disc and parts can be dissipated and cooled, avoiding the instability of the device for fine grinding after long-term use. At this time, it is necessary to shut down and disassemble the equipment, which reduces the working efficiency of the equipment and is time-consuming and labor-intensive. At the same time, it can also avoid the situation that the surface temperature of the fine grinding disc is high due to long-term work, which may affect the processed parts. It is simple and convenient to use and has strong practicality.

[0018] 2. In the utility model, by providing a dust box and a protective cover, when the device is in use, the vacuum cleaner in the dust box is turned on to absorb the waste dust generated during fine grinding, which protects the staff to a certain extent. At the same time, the provision of the protective cover enables the equipment to function continuously, improves work efficiency, and is simple and convenient to use, and has strong practicality.
