Description

Technical Field

[0001] The utility model relates to the field of processing equipment, in particular to a grinding device for producing high-precision rotating shafts. Background Art

[0002] In computer products, the hinge is usually used as the connection between the screen and the host of a laptop computer. This part allows the screen to be opened and closed at a certain angle. This hinge design not only provides support for the screen, but also ensures that the screen can rotate smoothly while maintaining structural stability and durability. In order to reduce friction and wear of the hinge during use, reduce noise, improve rotation accuracy and prevent impurity accumulation, the surface needs to be smoothed by grinding.

[0003] Existing grinding equipment adopts an open structure when grinding the rotating shaft and directly grinds the surface of the raw material. However, during transportation, impurities are easily attached to the surface of the raw material, which affects the surface roughness of the rotating shaft during grinding, making it easy for dust and impurities to accumulate, which may further aggravate the wear of the rotating shaft or cause failure, thereby reducing the service life of the rotating shaft.

[0018] The preferred embodiments of the present invention are described in detail below in conjunction with the accompanying drawings so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more precise definition of the protection scope of the present invention.

[0019] See also Figures 1 to 4A grinding device for producing high-precision rotating shafts includes a workbench 4 and a grinding structure, wherein the grinding structure is installed on the workbench 4, and the grinding structure includes a grinding roller 1, an auxiliary bracket 2 and a guide roller 3. The auxiliary bracket 2 is provided with an arc chamfer facing the guide roller 3, and the rotating shaft is placed between the auxiliary bracket 2 and the guide roller 3. The guide roller 3 is driven to rotate by an external motor, so that the rotating shaft can be transmitted. The grinding roller 1 rotates under the drive of the external motor to grind the rotating shaft.

[0020] The workbench 4 is also equipped with a cleaning structure that can remove impurities attached to the front and rear surfaces of the shaft after grinding, thereby avoiding uneven grinding and wear or failure during use caused by the rough front and rear surfaces of the shaft, thereby increasing the service life of the shaft.

[0021] The cleaning structure includes a protective structure for facilitating the processing of waste chips and a debris removal structure for processing the rotating shaft before and after processing.

[0022] The protective structure includes a protective cover 6 and a groove 5. The groove 5 is arranged on the workbench 4. The protective cover 6 covers the workbench 4 and completely covers the groove 5. The protective cover 6 is installed on the workbench 4 through an external lifting device to ensure that the waste chips after grinding will not fly around, thereby facilitating the collection of waste chips.

[0023] Two cleaning openings 7 are formed on both sides of the groove 5 and the protective cover 6. Since heavy waste chips will fall into the groove 5, the cleaning openings 7 are convenient for cleaning the waste chips.

[0024] The impurity removal structure includes a pre-processing cleaning structure and a post-processing cleaning structure, and the pre-processing cleaning structure and the post-processing cleaning structure are respectively arranged at the inlet 12 and the outlet 13 of the protective cover 6 in sequence along the conveying direction of the rotating shaft.

[0025] The pre-processing cleaning structure includes an air blower 8 and a first impurity removal brush 10. The air blower 8 is installed on the side wall of the protective cover 6 and is connected to the nozzle 9 through a conveying pipe. The nozzle 9 is tilted and arranged at the top of the inlet 12. Since the size of the rotating shaft entering the inlet 12 is irregular, the top is removed by means of the nozzle 9.

[0026] The first de-dusting brush 10 is arranged at the bottom of the inlet 12 . The first de-dusting brush 10 cooperates with the nozzle 9 at the top to remove de-dusting irregular rotating shafts entering the protective cover 6 from the inlet 12 .

[0027] The post-processing cleaning structure includes two second impurity removal brushes 11, which are symmetrically arranged at the upper and lower parts of the outlet 13, and are used to remove impurities from the regular rotating shaft of the protective cover 6 transmitted from the outlet 13 after grinding.

[0028] The first impurity removal brush 10 and the second impurity removal brush 11 both adopt a chamfered structure, and their heights increase successively from the inlet 12 to the outlet 13 , so as to gradually remove impurities on the outer wall of the shaft and avoid damaging the outer wall of the shaft.

[0029] Compared with the existing technology, the utility model provides a grinding device for producing high-precision rotating shafts. The device has a cleaning structure that can remove impurities attached to the surfaces of the rotating shaft before and after grinding, thereby avoiding uneven grinding and wear or failure during use caused by the rough surfaces of the rotating shaft before and after grinding, and increasing the service life of the rotating shaft.
