Self-adaption machining system and control method thereof and car body machining equipment

Abstract

The invention discloses a self-adaption machining system and a control method thereof and car body machining equipment. The self-adaption machining system is used for machining a workpiece and comprises an executing system, a motorized spindle, a milling tool head, a visual detecting device and a control device. The executing mechanism is in transmission connection with the motorized spindle and drives the motorized spindle to move. The motorized spindle drives the milling tool head to move. The executing mechanism and the motorized spindle are in communication connection with the control device, and the control device comprises a memorizer storing preliminary machining data and waste parameters of the workpiece. The control device carries out operation to obtain intermediate parameters, machining data is further obtained, the control device adjusts a first work parameter and a second work parameter according to post machining data and the waste parameters to control the motion of theexecuting mechanism and the motorized spindle correspondingly, and therefore it is guaranteed that the milling parameters of the milling tool head meet the requirement of the waste parameters. The self-adaption machining system and the control method thereof and the car body machining equipment have the advantages that the automation degree is high, production is safe and environment-friendly, theproduction and labor cost is greatly reduced, and the precision consistency is high.

Description

technical field [0001] The invention belongs to the technical field of mechanical processing, in particular, the invention relates to an adaptive processing system, a control method thereof, and a vehicle body processing equipment. Background technique [0002] At present, in the process of processing parts, especially metal parts, the processing part of the part will often destroy its surface flatness due to the processing force. The weld reinforcement produced by welding aluminum alloy materials by welding technology is one of the typical example. In recent years, with the promotion of lightweight vehicles in the automotive industry, more and more aluminum alloy materials are used on body-in-white.

Problems solved by technology

In recent years, with the promotion of lightweight vehicles in the automotive industry, more and more aluminum alloy materials are used on body-in-white. At present, MIG welding is commonly used for aluminum alloy connections in the industry. The problem of interference with parts assembly due to high seam reinforcement, although part of the welding can be avoided through 3D design and simultaneous engineering to reduce some interference, but some welds at key connections cannot be avoided. Therefore, in manufacturing During the body process, it is necessary to deal with the weld reinforcement that will cause interference, so as not to affect the assembly of the whole vehicle

[0003] At present, the treatment of weld reinforcement in the industry mainly uses pneumatic angle grinders to directly grind welds and solder joints. Because of its simple operation, it is widely used, but the disadvantages of this grinding method include: 1. Grinding During the process, the dust is flying, and the working environment is harsh, which is contrary to the occupational health requirements of the enterprise; 2. The aluminum dust after the pneumatic angle grinder has an explosion risk, and it needs to be equipped with explosion-proof dust removal equipment, and the investment cost of this equipment is high. Consumption is at least 37KWh; 3. Manual grinding requires high skills of employees and poor consistency; 4. Due to the accumulation of manufacturing tolerances in the weld reinforcement of some 3D space curves due to the accumulation of manufacturing tolerances in the body manufacturing process, its position accuracy fluctuates, and it is difficult to realize automatic operations , It also makes the industry accustomed to using manual grinding, but a large number of manual use will cause increased processing costs and management difficulties for enterprises
