Technical Field

[0001] The utility model relates to the technical field of grinding equipment, in particular to a grinding equipment for processing automobile valve sleeves. Background Art

[0002] The automobile valve sleeve is a key component in the automobile hydraulic system. It works closely with the valve core to control the flow, pressure and direction of the fluid. The valve sleeve is usually made of high-strength, high-hardness wear-resistant materials to ensure that it can operate stably for a long time under complex working conditions.

[0003] The grinding device for automobile valve sleeve processing is a device specially used for grinding, deburring, improving the surface finish of automobile valve sleeves, etc. After long-term use, the grinding disc on the grinding device will have grooves, cracks, and gaps on its surface, which will reduce the performance of the grinding disc, so the grinding disc needs to be replaced regularly.

[0004] At present, the grinding devices for automobile valve sleeve processing on the market often fix the grinding disc by bolts. Such a fixing method makes the replacement of the grinding disc cumbersome and time-consuming, which is not conducive to the use of the staff. Therefore, there is an urgent need for a grinding device for automobile valve sleeve processing that is convenient for replacing the grinding disc. Utility Model Content

DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Reference Figure 1-5A grinding device for automobile valve sleeve processing includes a grinding device body 1, an output shaft 11 is arranged on the grinding device body 1, a detachable grinding sheet 2 is installed on the output shaft 11, a column 7 is fixed and vertically arranged on the top of the grinding sheet 2, and a cavity 71 is opened at the bottom of the output shaft 11 corresponding to the column 7. A first installation cavity 31 is opened horizontally through the output shaft 11, the first installation cavity 31 is adapted to the column 7, a second installation cavity 32 is opened on the column 7 corresponding to the installation column 3, and the grinding sheet 2 is assembled at the bottom of the output shaft 11 through the installation column 3. Among them, a motor is arranged on the grinding device body 1, which can drive the output shaft 11 to rotate, so that the automobile valve sleeve can be polished by the rotating grinding sheet 2. It is also worth noting that the specific structure of the grinding equipment body 1 and the grinding sheet 2 and their working methods are all existing technologies currently disclosed on the market. They are all main common knowledge known to technical personnel in this field, and are not the main technical problems to be solved in this technical solution. Therefore, they are not elaborated in this utility model.

[0022] When the column 7 is inserted into the cavity 71, the first installation cavity 31 and the second installation cavity 32 are adapted and aligned. Both ends of the column 7 extend from the output shaft 11, and the ends of the column 7 vertically penetrate to form a limiting cavity 41. The limiting column 4 is fixedly installed on the outer side of the clamp 5, and the limiting column 4 is adapted to the limiting cavity 41. The fixing of the column 7 can be achieved by the adaptation and clamping between the limiting column 4 and the limiting cavity 41.

[0023] A vertical clamping cavity 51 is provided on the outer wall of the output shaft 11 above both ends of the first mounting cavity 31, and a clamping member 5 is movably provided in the clamping cavity 51. By providing the clamping member 5 and the clamping cavity 51, the limiting column 4 can be located outside the output shaft 11 and move up and down.

[0024] Among them, magnetic blocks 6 are fixedly arranged on the outer wall of the output shaft 11 below the two ends of the first installation cavity 31, and the bottom of the limit column 4 is set to a magnetic material that is adapted to be attracted to the magnetic block 6. Through the magnetic attraction force between the limit column 4 and the magnetic block 6, it can be ensured that the limit column 4 is not easy to loosen during the grinding process.

[0025] In the present invention, when the user needs to install the grinding sheet 2, he only needs to insert the column 7 on the top of the grinding sheet 2 into the cavity 71 opened at the bottom of the output shaft 2. Then, the mounting column 3 is inserted into the first mounting cavity 31 on one side of the output shaft 11, and the mounting column 3 passes through the second mounting cavity 32 and extends from the first mounting cavity 31 on the other end, so that the output shaft 11 and the grinding sheet 2 can be clamped by the mounting column 3.

[0026] Furthermore, when the user inserts the installation column 3, the limiting columns 4 on both sides need to be moved upward. Since the limiting columns 4 and the clamping member 5 are fixedly connected, the movable length of the limiting columns 4 is limited. And since the clamping cavity 51 is not connected to the first installation cavity 31, the clamping member 5 and the limiting columns 4 will not fall off during the movement.

[0027] Furthermore, when the limiting column 4 moves upward, the user can insert the installation column 3 into the first installation cavity 31. After the installation column 3 is inserted, the user only needs to insert the limiting columns 4 on both sides into the limiting cavity 41 on the installation column 3, so as to realize the clamping of the installation column 3, thereby completing the installation of the grinding sheet 2. This assembly method is very convenient. When the user needs to disassemble the grinding sheet 2, he only needs to lift the limiting columns 4 on both sides, and then take out the installation column 3, so as to realize the disassembly of the grinding sheet 2.

[0028] Furthermore, when the limiting column 4 is assembled in the limiting cavity 41, due to the self-weight of the limiting column 4 and the magnetic attraction between the limiting column 4 and the magnetic attraction block 6, it is possible to prevent the limiting column 4 from loosening during the grinding process, thereby improving the stability of the grinding sheet 2 after installation.

[0029] In the utility model, the grinding processing of the automobile valve sleeve can be realized through the setting of the grinding device body 1 and the grinding sheet 2. The grinding sheet 2 can be quickly installed on the output shaft 11 through the setting of the limit column 4, the clamp 5, the magnetic block 6 and the column 7. This installation method is simple in steps and quick and convenient in operation, which is convenient for users to replace the grinding sheet 2.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
