Description

Technical Field

[0001] This utility model belongs to the field of automotive parts polishing technology, and relates to an automated polishing device for automotive parts using a lead screw. Background Technology

[0002] Polishing refers to the process of using mechanical, chemical, or electrochemical methods, through polishing tools and abrasive particles or other polishing media, to modify the surface of a workpiece, reducing its roughness and obtaining a bright, smooth surface. In automobile production, polishing is one of the key steps in improving the appearance quality of automotive parts. When threads are milled onto the outer surface of a lead screw, polishing is usually required to further improve its surface quality, gloss, and reduce surface resistance. Existing polishing equipment involves manual loading and polishing. The long waiting time during loading can cause production interruptions, affecting the consistency of polishing quality. Furthermore, to ensure processing efficiency, the loading process requires a large amount of manual labor, resulting in wasted manpower. Utility Model Content

[0003] The purpose of this invention is to provide an automated polishing device for lead screws used in automotive parts, which solves the problem of production interruptions caused by long material loading waiting times, thereby affecting the consistency of polishing quality.

[0004] The objective of this utility model can be achieved through the following technical solutions:

[0011] Furthermore, the feeding mechanism also includes a first electric slide rail disposed opposite to the first feeding tray and the second feeding tray, a first crossbeam slidably disposed on the first electric slide rail, a first telescopic cylinder disposed on the first crossbeam, first positioning guide rods arranged side by side on both sides of the first telescopic cylinder, and a first horizontal plate driven by the first telescopic cylinder. The first gripper is disposed at the bottom of the first horizontal plate; the output end of the first telescopic cylinder is connected to the first horizontal plate. The first positioning guide rods ensure that the first horizontal plate remains stable when moving up and down.

[0012] Furthermore, the polishing machines are arranged side by side, and each polishing machine includes a brush located on one side of the support platform and a drive motor for driving the brush to rotate.

The second positioning guide rods ensure that the second cross plate remains stable when moving up and down.

[0018] Furthermore, the first telescopic cylinder and the second telescopic cylinder are common types of cylinders available on the market.

[0019] Furthermore, the first and second grippers are common mechanical grippers.

Then, the lead screw 110 to be polished is placed in the first feeding tray 101. The first feeding tray 101 is pushed back to its original position, and the controller button electrically connected to the third telescopic cylinder is pressed. The third telescopic cylinder, located at the bottom of the first feeding tray, rises and passes through the limiting hole of the bracket of the first feeding tray 101 to lock the first feeding tray 101 and prevent it from shifting during equipment operation. Then, press the controller button electrically connected to the first gripper 108. The first gripper 108 picks up the lead screw 110 in the first loading tray 101 and places it onto the first conveyor belt 109. The first conveyor belt 109 then conveys the lead screw 110 to the polishing mechanism for polishing. While processing the lead screw 110 in the first loading tray 101, the second loading tray 102 is loaded in the same way. When the lead screw 110 in the first loading tray 101 is finished, the lead screw in the second loading tray can be processed immediately, ensuring the continuity of the processing operation.

[0052] The first telescopic cylinder 105 and the second telescopic cylinder 305 in the above embodiments are common types of cylinders on the market; the first gripper 108 and the second gripper 308 are common mechanical grippers.

[0053] The automated polishing device in the above embodiments effectively ensures the continuity of the lead screw polishing feeding process, thereby guaranteeing the continuity and efficiency of the entire processing. This design not only improves production efficiency but also optimizes the production process, reduces the need for manual intervention, and enhances the level of automation.
