[0001] This utility model relates to the technical field of boring processing equipment, specifically to a boring processing equipment for vehicle modification. Background Technology

[0002] In the field of machining, lathes are machine tools that primarily use cutting tools to turn rotating workpieces; boring machines are mainly used to bore various holes and hole systems on workpieces, and are particularly suitable for machining multi-hole box-shaped parts. They are also a widely used type of machine tool in mechanical manufacturing and processing. However, both types of machine tools have limited functions. When production tasks are urgent, the number of boring machines may be insufficient, and purchasing additional boring machines will increase the company's production costs.

[0003] Based on this, this utility model designs a boring machine for car modification to solve the above problems. Utility Model Content

Then, the position of the movable base 4 is adjusted, and the fixing mechanism 5 is moved to the workpiece. After loosening the nut 5010, the second roller 506 can be lifted upward, thereby adjusting the height of the second roller 506 so that the second roller 506 abuts against the lower end of the workpiece. Then, by rotating the first lead screw 5042, the position of the first roller 5044 on the stand 504 is adjusted. Adjustments are made, and then the two uprights 504 are brought closer together by rotating the reciprocating screw 502, so that the two first rollers 5044 come into contact with the workpiece. The two first rollers 5044 and the second roller 506 clamp and limit the workpiece, so that the workpiece has good stability during boring. The rotation of the second screw 7 driven by the motor 8 can drive the moving frame 9 to move. The boring machine is performed on the workpiece by the cutting tool fixed in the tool holder 10, so that the original lathe can be used as a boring machine.
