Support arm moving and grinding device based on overhead working truck manufacturing

Abstract

The invention provides a support arm moving and grinding device based on overhead working truck manufacturing, relates to the field of grinding, and aims to solve the problems that when different grinding requirements are met, a grinding mechanism is not convenient to mount and maintain, a multi-gear grinding force adjusting structure is lacked, and when slight grinding is needed, a heavy block is not convenient to add for stress grinding. The support arm moving and grinding device comprises a moving part, the bottom of the moving part is of an arc-shaped structure, a threaded hole is formed in the bottom of the moving part, a moving table comprises an adjusting plate, two round holes are formed in the adjusting plate, guide rods are inserted into the round holes, the bottom of the adjusting plate makes contact with the top ends of springs on the outer sides of the guide rods, and the adjusting plate is inserted into limiting grooves. When the grinding force needs to be adjusted, the inner end of the adjusting plate can be controlled to be inserted into the limiting grooves in different positions, so that the springs are compressed to different degrees, the moving table is pulled through different force, and thus the force of the moving table can be adjusted for grinding.

Description

technical field [0001] The invention belongs to the technical field of grinding, and more specifically relates to a mobile grinding device for a support arm manufactured on the basis of an aerial work vehicle. Background technique [0002] When the aerial work vehicle is manufactured, it is usually necessary to grind the support arm of the work vehicle, so that the protrusions or other attachments of the support arm can be removed by grinding, so that the surface of the support arm can be kept flat; [0003] Due to the long support arm, it is easy to shake or shift the support arm when grinding it, the fixing effect is not good, and the fixing force is weak. If the support arm rolls or collapses, it is easy to cause injury to the staff. When the grinding needs are required, the installation and maintenance of the grinding mechanism is relatively inconvenient, and there is a lack of multi-level structure to adjust the grinding force. When light grinding is required, it is inc...

AI Technical Summary

Problems solved by technology

[0004] In order to solve the above-mentioned technical problems, the present invention provides a mobile grinding device for a support arm based on an aerial work vehicle to solve the problem that due to the long support arm, it is easy to cause shaking or displacement of the support arm when grinding it. The effect is not good, and the fixing strength is weak. If the support arm rolls or collapses, it will easily cause injury to the staff. When facing different grinding needs, the installation and maintenance of the grinding mechanism is more inconvenient, and there is no structure for multi-level adjustment of the grinding strength. , when light grinding is required, it is inconvenient to add heavy blocks for forced grinding
