Device for correcting precision of rack installation surface of lathe body of lathe

Abstract

The invention relates to a device for correcting the precision of a rack installation surface of a lathe body of a lathe, which is arranged on a lathe saddle of the lathe in the assembling process for correcting the rack installation surface of the lathe body of the lathe. The invention is suitable for large and heavy numerical control lathes with high installation precision requirement and long length specification. The device comprises a cutter clamp, wherein the cutter clamp is distributed and arranged on the lathe saddle of the lathe, a wide edge plane cutter is arranged in the cutter clamp, the cutter is regulated to a proper position through a regulation screw bolt arranged on a regulation plate, and then, the cutter is tightly pressed, the cutter clamp moves synchronously along with an electric tail seat of the lathe for realizing the correction on the rack installation surface of the lathe body of the lathe, the position tolerance between the corrected rack installation surface of the lathe body and the reference surface can be easily ensured, the precision requirement of the product drawing can be ensured, the work intensity of workers can be reduced, and the production efficiency can be improved.

Description

technical field [0001] The invention relates to a device for correcting the accuracy of the rack mounting surface of the lathe bed, which is installed on the saddle of the lathe bed during the assembly process and corrects the mounting surface of the rack of the lathe bed. Longer large and heavy CNC lathes. Background technique [0002] At present, the longitudinal feed of long lathes (large and heavy lathes) in China generally adopts rack and pinion transmission, which has strong rigidity and good stability. However, due to the long mounting surface of the rack, the processing of it and the guide surface of the Z-direction feed rail is not completed in one clamping, and the structure of the bed is complex and easy to deform, which may easily cause the position tolerance of the two sides to be out of tolerance. Our company's product CKH61125 / 8000 heavy-duty CNC lathe has the most serious parallelism between the mounting surface of the primary tooth bar and the guiding surfa...

Problems solved by technology

[0003] The purpose of the present invention is to overcome the lack of capability of the original processing equipment and the out-of-tolerance problem of the position accuracy of the bed rack mounting surface and the reference guide rail surface caused by the deformation caused by the complex structure, so as to ensure that the machined lathe bed rack mounting surface and The position tolerance requirement of the guide surface of the guide rail is convenient for installation and debugging, saves assembly time, improves production efficiency, and solves the problem of insufficient processing equipment capacity and deformation of the bed to provide a device for correcting the accuracy of the rack mounting surface of the lathe bed. After repairing, the parallelism between the mounting surface of the bed rack and the guide surface of the guide rail reaches 0.01mm within a length of 8000mm, and the actual accuracy is much higher than the accuracy requirement of the product drawing
