Description

Technical Field

[0001] This utility model relates to the field of automotive parts grinding technology, specifically an automotive parts grinding device. Background Technology

[0002] Automotive parts refer to the various units that make up a car and the products that serve the car. Apart from large components such as the frame and body, everything else can be called automotive parts. An automotive parts grinding device is a piece of equipment used to grind automotive parts.

[0003] The patent document with authorization announcement number CN222537256U describes a grinding device for automotive parts. The described solution is to drive the driven pulley and the threaded rod to rotate simultaneously with the rotation of the active pulley, and to perform double-sided grinding of the tube by the rotation of the external grinding ring, without the need to change equipment for grinding.

[0004] The above-mentioned technology has the problem of not being able to grind square pipes of different diameters. If it is necessary to grind square pipes of various sizes, but the grinding device can only handle a portion of them, it is necessary to frequently change the grinding equipment or adjust the process flow, which leads to a decrease in production efficiency. If an unsuitable grinding device is used to forcibly grind pipes beyond its capacity, it may lead to a decrease in grinding quality, such as uneven surface or material damage due to over-grinding.

Another second bevel gear 509 and another first bevel gear 506 rotate, thereby driving the two grinding rollers 504 to rotate. Then, the third motor 702 is started, which drives the threaded rod 703 to rotate. Then, under the action of the two support bars 701, it drives the slide plate 300 and the grinding rollers 504 to rise and fall, thereby grinding the square tube. After grinding two sides, the fourth motor 902 can be started, which drives the first rotating gear 903 to rotate, thereby driving the second rotating gear 904 and the movable column to rotate, thereby driving the support frame 200 and the square tube to rotate on the top of the worktable 100, so that the other two sides of the square tube can be ground. Then, the second bidirectional lead screw 802 can be rotated, so that the square tube can be rotated 180 degrees. Then, the second bidirectional lead screw 802 is rotated again to fix the square tube, so that the areas that were not ground can be ground.
