[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1-5 As shown, a trimming structure for a starter switch metal part includes an adjusting mechanism 1, with a pressing mechanism 2 above the adjusting mechanism 1. The adjusting mechanism 1 includes a motor 105 and a motor 108. The pressing mechanism 2 includes a lifting rod 201, with an extension rod 203 fixedly connected to one bottom end of the lifting rod 201. The upper end of the outer wall of the extension rod 203 is threaded, and symmetrical limit grooves 204 are formed at the lower end of the outer wall of the extension rod 203. A ball bearing 205 is movably installed in the middle of the bottom surface of the extension rod 203. A rotating ring 206 is also threaded onto the upper end of the outer wall of the extension rod 203. A pressure sleeve 207 is rotatably connected to the bottom of the rotating ring 206. A limit block 208 is fixedly connected to the inner side of the pressure sleeve 207, and the limit block 208 is slidably connected to each limit groove 204. A buffer pad 209 is fixedly connected to the bottom surface of the pressure sleeve 207. The lower end of the outer wall of the ball bearing 205 extends below the extension rod 203. Figure 2 As shown, the buffer pad 209 is made of rubber. The buffer pad 209 prevents the pressure sleeve 207 from pressing too tightly, which could damage the surface of the metal parts.

[0028] The adjustment mechanism 1 includes a base plate 101. A splash guard 107 is fixedly installed on the top of the base plate 101 and below the buffer pad 209. The interior of the splash guard 107 is fixedly installed with a second motor 108. The output shaft of the second motor 108 extends upward through the splash guard 107, and a support plate 109 is fixedly connected to the top of the output shaft of the second motor 108. Figure 1 As shown, motor 2 108 is a valve-type self-locking motor in the prior art. The output shaft of motor 2 108 self-locks after it stops rotating to prevent the support plate 109 from rotating.

[0029] A column 110 is fixedly connected to the top of the base plate 101. A lead screw 114 is rotatably connected to the upper end of the outer wall of the column 110. The top of the lead screw 114 protrudes from the column 110 and is fixedly connected to a knob 115. A lifting sleeve 202 is fixedly connected to the outer wall of the lifting rod 201 on the side away from the extension rod 203. The inner wall of the lifting sleeve 202 is threaded onto the lead screw 114. One side of the outer wall of the lifting sleeve 202 is also slidably connected along the outer wall of the column 110. Figure 1 As shown, the lifting sleeve 202 moves in a straight line along the side of the column 110;

[0030] A negative pressure fan 111 is fixedly installed on the inner wall of the column 110, below the lead screw 114. The input end of the negative pressure fan 111 faces the support plate 109. An outer support frame 112 is fixedly connected to the inner wall of the column 110 near the output end of the negative pressure fan 111. A dust collection bag 113 is fixedly connected to the inner side of the outer wall of the outer support frame 112. Figure 1 , Figure 4 As shown, the dust collection bag 113 is a cloth bag, and the gaps on its surface can ensure the normal output of the negative pressure fan 111;

[0031] A movable rail 102 is provided on the top surface of the base plate 101 on the side away from the column 110. A movable frame 103 is slidably connected to the inner side of the movable rail 102. The top side of the movable frame 103 is fixedly installed with a motor 105. A grinding wheel 106 is fixedly connected to the output shaft of the motor 105, and the rotating shaft of the grinding wheel 106 is rotatably connected to the inner side of the movable frame 103. A push rod 104 is fixedly connected to the middle of the outer wall of the movable frame 103. Both sides of the outer wall of the splash guard 107 extend upwards, such as... Figure 5 As shown, the sides of the splash guard 107 prevent grinding debris from splashing.

[0032] The working principle of this utility model:

[0033] Place the metal part to be polished on the support plate 109. Then, rotate the lead screw 114 by the knob 115. The thread on the surface of the lead screw 114 pushes the lifting rod 201 to slide along the side of the column 110. Thus, the pressure sleeve 207 under the lifting rod 201 presses down and fixes the metal part through the buffer pad 209. Start the motor 105 to drive the polishing wheel 106 to rotate. The push rod 104 makes the moving frame 103 slide along the inside of the moving rail 102. The polishing wheel 106 approaches and polishes the uneven side of the metal part. Next, when the negative pressure fan 111 is turned on, the debris generated by polishing is pushed into the dust collection bag 113 by the airflow.

[0034] In addition, when the metal part is being ground on different sides, the rotating ring 206 is rotated, and the upper thread of the extension rod 203 pushes the rotating ring 206 to move upward, which in turn drives the pressure sleeve 207 to move upward, and the buffer pad 209 separates from the metal part. At this time, the motor 108 is started to drive the support plate 109 to rotate, and the support plate 109 drives the metal part to adjust its angle. At this time, the upper part of the metal part is held in place by the ball bearing 205 to prevent the metal part from separating from the support plate 109.

[0035] The above description provides a detailed account of one embodiment of the present invention. However, this description is merely a preferred embodiment and should not be construed as limiting the scope of the present invention. All equivalent variations and improvements made within the scope of the claims of the present invention should still fall within the patent coverage of the present invention.
