Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0054] Example 1

[0055] See also Figure 1-9 The present invention provides a technical solution: a computer mechanical parts processing device, comprising:

[0056] The workbench 1 is arranged horizontally, and the bottom of the four corners of the workbench 1 is fixedly installed with brackets 2, and the bottom end of the brackets 2 is fixedly installed with feet, and a cross frame 1 3 and a cross frame 2 4 are respectively fixedly installed between each two adjacent brackets 2. The brackets 2 and the feet can play a role in firmly supporting the entire workbench 1, and the installed cross frames 1 3 and cross frames 2 4 can play a role in stabilizing the adjacent brackets 2;

[0057] A side plate 5 is vertically fixed to the top surface of the left end of the workbench 1;

[0058] A grinding assembly 6 is disposed above the workbench 1 and is connected to the right side surface of the side plate 5;

[0059] An auxiliary component 7, connected to the grinding component 6;

[0060] The cleaning and blowing component 8 is connected to the polishing component 6 .

[0061] The grinding assembly 6 comprises:

[0062] The left end of the cylinder 61 is vertically fixed to the right side of the side plate 5, and a mounting plate 62 is fixedly installed on the right end of the cylinder 61. A clamp for clamping computer mechanical accessories is fixedly installed on the side of the mounting plate 62 away from the cylinder 61 (the clamp is not drawn in the figure);

[0063] The F-shaped plate 63, the lower end of which is connected to the auxiliary component 7;

[0064] There are multiple rebound components 64, which are divided into two groups. One group is connected to the upper plate in the F-shaped plate 63, and the other group is connected to the lower plate in the F-shaped plate 63. The connection method of the two groups is the same.

[0065] In the specific implementation process, the shell to be polished is first clamped with a clamp, and then the clamped shell is moved between the polishing balls 641 by using the cylinder 61, and the reciprocating extension and contraction of the cylinder 61 is controlled to achieve repeated friction contact between the shell and the polishing balls 641 to achieve the polishing work.

[0066] In this embodiment, the rebound component 61 includes:

[0067] The top and bottom surfaces of the hollow column 643 are all hollowed out, and the outer wall of the hollow column 643 is fixedly mounted to the inner wall of the circular opening on the surface of the F-shaped plate 63, and the inner wall of the hollow column 643 is provided with an inner annular groove;

[0068] The annular block 644 is disposed in the hollow column 643, and the outer wall of the annular block 644 is slidably disposed with the inner wall of the annular groove provided on the inner wall of the hollow column 643, and the annular block 644 can move up and down relative to the hollow column 653 along the annular groove;

The top of the spring 645 is fixedly installed on the bottom surface of the annular block 644, and the bottom end of the spring 645 is fixedly installed on the bottom of the inner wall of the hollow column 643. During the grinding process of computer accessories, the grinding ball 641 will be squeezed, and the spring 645 will be compressed. During the grinding process, part of the grinding ball 641 is sometimes subjected to force, so that the grinding ball 641 can be vibrated up and down under the action of the spring 645, and the debris on the surface of the grinding ball 641 can be shaken off to avoid affecting the grinding effect. The distance between each upper and lower adjacent grinding ball 641 is less than the thickness of the computer mechanical accessories, so that the computer accessories can be clamped, the contact force is increased, and the friction grinding process is convenient.

[0070] Example 2

[0071] On the basis of the above embodiment, the auxiliary component 7 comprises:

[0072] The auxiliary plate 71 has a top surface fixedly mounted to the bottom surface of the mounting plate 62, and the front and rear ends of the auxiliary plate 71 are provided with tooth openings;

[0073] The gear 73 is meshed with the teeth of the auxiliary plate 71, and a short shaft 74 is fixedly installed on the inner wall of the gear 73. The bottom end of the short shaft 74 is rotatably arranged with the top surface of the workbench 1 through a bearing;

[0074] The front side of the left end of the auxiliary rod 72 is provided with a toothed opening for meshing with the gear 73. The auxiliary rod 72 is slidably provided with a guide rail 75. The bottom surface of the guide rail 75 is fixedly mounted to the top surface of the workbench 1. The top surface of the auxiliary rod 72 is fixedly mounted to the bottom surface of the F-shaped plate 63.

[0075] In the specific implementation process, during the reciprocating movement of the mounting plate 62, the same movement trend of the auxiliary plate 71 can be achieved, so that the gear 73 can be rotated, and the auxiliary rod 72 can be moved under the rotation of the gear 73, and the F-type plate 63 can be moved under the movement of the auxiliary rod 72, and the moving direction of the F-type plate 63 is opposite to the moving direction of the clamped shell, and the moving trend of the grinding ball 641 is consistent with the moving trend of the F-type plate 63, which can increase the relative friction between the grinding ball 641 and the shell, and strengthen the grinding treatment intensity of the shell.

[0076] In this embodiment, the length of the auxiliary rod 72 is longer than the length of the guide rail 75 , which can prevent the auxiliary rod 72 from being separated from the guide rail 75 .

[0077] Example 3

[0078] On the basis of the above-mentioned embodiment, the cleaning and blowing component 8 comprises:

[0079] The long tube 81 is arranged parallel to the top of the F-shaped plate 63;

[0080] There are multiple connecting tubes 82, wherein the top ends of some connecting tubes 82 are connected to the lower surface of the long tube 81, and the connecting tubes 82 located at the left and right positions are connected to the left and right ends of the long tube 81 respectively, and the bottom ends of the connecting tubes 82 are connected to the top end of the hollow column 643;

[0081] The piston rod 85 has an upper end which is slidably disposed on the inner wall of the connecting pipe 82, and a lower end of the piston rod 85 which is fixedly mounted on the top surface of the annular block 644;

[0082] The auxiliary tube 83 has its top end connected to the lower surface of the long tube 81 , and its bottom end penetrates the upper surface of the F-shaped plate 63 and extends into the F-shaped plate 63 . The bottom end of the auxiliary tube 83 is connected to two nozzles 84 .

[0083] In the specific implementation process, during the up and down vibration of the grinding ball 641, the rebound column 642 and the annular block 644 have the same up and down reciprocating motion tendency. Since the annular block 644 is fixedly installed with the piston rod 85, the piston rod 85 will also form an up and down reciprocating motion tendency, so that there is airflow in the connecting pipe 82. The airflow enters the auxiliary pipe 83 and is finally blown toward the grinding ball 641 from the nozzle 84. The debris on the surface of the grinding ball 641 is blown away with the vibration effect, which is convenient for the grinding effect of the grinding ball 641.

[0084] In this embodiment, the nozzle 84 is tilted, and the air outlet of the nozzle 84 is inclined toward the grinding ball 641, so that the air can be effectively blown toward the grinding ball 641, thereby enhancing the force of blowing away debris.

[0085] Working principle: First, the housing to be polished is clamped with a clamp, and then the housing is polished between the polishing balls 641 by controlling the reciprocating motion of the air cylinder 61. During the polishing process, the polishing balls 641 adjacent to each other at the beginning will be squeezed by the housing, but during the reciprocating motion, the polishing balls 641 will be indirectly stressed, and under the stress, the rebound column 642 and the annular block 644 will also form an up and down reciprocating action, so that the piston rod 85 can be reciprocated up and down. During the up and down reciprocating motion of the piston rod 85, an airflow will be formed in the connecting pipe 82, and the airflow will enter through the long pipe 81. The air flows into the auxiliary pipe 83 and finally blows toward the grinding ball 641 from the nozzle 84. With the up and down vibration of the grinding ball 641, the debris on the surface of the grinding ball 641 can be better cleaned, thereby avoiding affecting the grinding process of the shell by the grinding ball 641. The reciprocating movement of the cylinder 61 can make the mounting plate 62 drive the auxiliary plate 71 to reciprocate, thereby making the gear 73 rotate. When the gear 73 rotates, the auxiliary rod 72 can drive the F-type plate 63 to move, and finally the grinding ball 641 and the shell form an opposite movement trend, thereby increasing the friction between the grinding ball 641 and the shell and enhancing the grinding effect.
