Assembling and scraping method of spindle box square hole assembling and scraping device

Abstract

The invention discloses an assembling and scraping method of a spindle box square hole assembling and scraping device. The process is as follows: a moving seat is pushed, so that a ram part moves stably on a precision linear guide track to a position near the front end of a spindle box; a handle on a ram support adjusting mechanism is rotated, and a center of the ram part and a square hole center of the spindle box are enabled to be equal in height by the aid of a lead screw nut adjusting mechanism; a traction cable is connected with two ends of the ram part, bypasses a fixed pulley on a traction pulley support, and is connected with a lifting hook of a travelling crane; the ram part is pushed into a square hole of the spindle box; and the ram part is pulled forward and backward through the movement of the lifting hook on the travelling crane, and assembling and scraping are performed. With the adoption of the technical scheme, the production efficiency is improved, a potential danger that the ram part collides into the spindle box, so that a workpiece is bumped or damaged is eliminated, the manufacturing accuracy of a product is improved, the product quality is greatly improved, and human power and material resources are saved.

Description

technical field [0001] The invention belongs to the technical field of machine tool manufacturing process equipment, and relates to the processing technology of a spindle box of a large machine tool, especially a heavy machine tool such as a heavy floor milling and boring machine. More specifically, the present invention relates to a scraping and grinding method for assembling a scraping and grinding device with a square hole in a headstock. Background technique [0002] Improving the accuracy and stability of machine tools has always been the development direction of machine tool manufacturing technology, and using and designing various novel and practical process equipment and process methods to achieve the high precision required by machine tool manufacturing and improve production efficiency is the key to machine tool manufacturing enterprises the goal that is pursued. [0003] CNC heavy-duty floor milling and boring machine is a technology-intensive product integrating...

AI Technical Summary

Problems solved by technology

[0005] In the prior art assembly scraping method described above, since the rigidity of the box support frame and the ram support frame is poor and not fixed, repeated adjustments are required to complete the scraping of the guide rail surface of the square hole of the spindle box, and there is a slight Inadvertently, the ram part may hit the spindle box and damage the workpiece, which is not safe, and the production efficiency is also very low, and it is difficult to ensure the required scraping precision
