Description

Technical Field

[0001] The utility model relates to the technical field of brake discs, in particular to a brake disc structure of a grinding machine. Background Art

[0002] In modern society, grinding machines are commonly used. There are various grinding machines sold on the market, each with different design concepts, aiming to meet the usage requirements of different users. However, although these grinding machines can generally meet the usage requirements, their structural designs are not very ingenious and there is no braking device. That is, after stopping working, due to inertia, the grinding disc will continue to rotate for a certain period of time. However, after people finish using the grinding machine, they still need to hold the grinding machine for a certain period of time until the grinding disc stops rotating before they can put it down. Therefore, a brake disc is needed to quickly stop the rotation of the grinding disc.

[0003] In the existing brake disc, after the grinding machine finishes the grinding work, by pressing the brake disc against the upper part of the grinding disc, the friction of the grinding disc is increased, so as to realize quickly stopping the rotation of the brake disc. After long-term use, the bottom of the brake disc will be worn, which will affect the braking effect on the grinding disc. It is necessary to replace the rubber brake at the bottom of the brake disc to ensure the braking effect of the brake disc on the grinding disc. However, when replacing the rubber brake, the rubber brake is installed inside the brake disc, making the replacement of the rubber brake more troublesome.

[0004] Therefore, we propose a brake disc structure of a grinding machine. Content of the Utility Model

[0005] To solve the above-mentioned technical problems, the utility model provides a brake disc structure of a grinding machine.

[0006] The utility model is realized by the following technical solutions: A brake disc structure of a grinding machine includes a mounting ring. Two L-shaped mounting plates are installed on the top of the mounting ring. A threaded rod is rotatably connected to the top of the mounting ring. A threaded cylinder is threadedly connected to the outside of the threaded rod. The bottom of the threaded cylinder is fixedly connected to a connecting ring. The inside of the connecting ring is slidably connected to the inside of the mounting ring. An annular rubber brake is installed inside the connecting ring through a magic tape.

[0007] As a further improvement of the above solution, a groove is opened at the bottom of the mounting ring, and the connecting ring is installed inside the groove to ensure the normal operation of the connecting ring.

[0008] As a further improvement of the above solution, ventilation openings are equally spaced on the surface of the mounting ring to facilitate heat dissipation of the device.

[0009] As a further improvement of the above solution, mounting holes are opened on the surface of the L-shaped mounting plate, and bolts are installed in the mounting holes to facilitate the installation of the mounting ring.

[0010] As a further improvement of the above solution, two sliders are fixedly connected to the surface of the connecting ring, and sliding grooves adapted to the sliders are provided on both sides of the inner wall of the groove to ensure the normal movement of the connecting ring.

[0011] As a further improvement of the above solution, a limiting groove is provided at the bottom of the connecting ring, and the annular rubber brake is installed inside the limiting groove, which is convenient for installing the annular rubber brake.

[0012] As a further improvement of the above solution, a hand wheel is fixedly connected to the top of the threaded rod, which is convenient for rotating the threaded rod.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. By setting the mounting ring, the annular rubber brake is installed inside the connecting ring through the magic tape. When the threaded rod is rotated, under the action of the two sliders, the threaded cylinder moves upward, so that the connecting ring moves into the inside of the mounting ring, and the connecting ring moves into the inside of the mounting ring. At the same time, the annular rubber brake is located below the bottom of the mounting ring. After the annular rubber brake is installed, the mounting ring is installed on the grinding machine through two L-shaped mounting plates, which is convenient for the annular rubber brake to brake the grinding disc on the grinding machine, making the installation of the annular rubber brake very convenient.

[0015] 2. By setting the threaded rod, after long-term use, when the annular rubber brake is worn too much and needs to be replaced, rotate the threaded rod to make the threaded cylinder move downward. Under the action of the slider, the connecting ring moves downward, so that the connecting ring moves out of the inside of the mounting ring, and the annular rubber brake is exposed. Then pull the annular rubber brake downward to replace the annular rubber brake. After the replacement is completed, reverse the threaded rod to reset the connecting ring, making the replacement of the annular rubber brake very convenient. BRIEF DESCRIPTION OF THE DRAWINGS

It should be noted that, on the premise of no conflict, any combination can be formed among the following-described embodiments or technical features to form a new embodiment. Embodiment

[0022] Please refer to Figures 1-3 , the braking disc structure of a grinding machine in this embodiment includes a mounting ring 1. Vent holes are evenly spaced on the surface of the mounting ring 1 to facilitate heat dissipation of the device. Two L-shaped mounting plates 2 are installed on the top of the mounting ring 1. Mounting holes are provided on the surface of the L-shaped mounting plates 2, and bolts are installed in the mounting holes to facilitate the installation of the mounting ring 1. A threaded rod 3 is rotatably connected to the top of the mounting ring 1. A handwheel is fixedly connected to the top of the threaded rod 3 to facilitate the rotation of the threaded rod 3. A threaded barrel 4 is threadedly connected to the outside of the threaded rod 3. A connecting ring 5 is fixedly connected to the bottom of the threaded barrel 4. Two sliders are fixedly connected to the surface of the connecting ring 5. Sliding grooves adapted to the sliders are provided on both sides of the inner wall of the groove to ensure the normal movement of the connecting ring 5. A groove is provided at the bottom of the mounting ring 1, and the connecting ring 5 is installed inside the groove to ensure the normal operation of the connecting ring 5. The inside of the connecting ring 5 is slidably connected to the inside of the mounting ring 1. A limiting groove is provided at the bottom of the connecting ring 5, and an annular rubber brake 7 is installed inside the limiting groove to facilitate the installation of the annular rubber brake 7. The annular rubber brake 7 is installed inside the connecting ring 5 through a magic tape 6.

[0023] The implementation principle of the braking disc structure of a grinding machine in this application embodiment is as follows: The annular rubber brake 7 is installed inside the connecting ring 5 through the magic tape 6. When the threaded rod 3 is rotated, under the action of the two sliders, the threaded barrel 4 moves upward, so that the connecting ring 5 moves towards the inside of the mounting ring 1, making the connecting ring 5 move into the inside of the mounting ring 1. At the same time, the annular rubber brake 7 is located below the bottom of the mounting ring 1. After the annular rubber brake 7 is installed, the mounting ring 1 is installed on the grinding machine through the two L-shaped mounting plates 2, facilitating the annular rubber brake 7 to brake the grinding disc on the grinding machine, making the installation of the annular rubber brake 7 very convenient.

[0024] After long-term use, the annular rubber brake 7 wears too much and needs to be replaced. Rotate the threaded rod 3 to make the threaded barrel 4 move downward. Under the action of the slider, the connecting ring 5 moves downward, so that the connecting ring 5 moves out of the inside of the mounting ring 1, and the annular rubber brake 7 is exposed. Then pull the annular rubber brake 7 downward to replace the annular rubber brake 7. After the replacement is completed, reverse the threaded rod 3 to reset the connecting ring 5, making the replacement of the annular rubber brake 7 very convenient.
