Machining method for X-shaped sliding block guide rails

Abstract

The invention relates to a machining method for X-shaped sliding block guide rails. According to the method, firstly, rough machining and finish machining are performed on an X-shaped sliding block; then the bottom plane of the X-shaped sliding block is set as a reference surface, and two adjacent side surfaces of the X-shaped sliding block are set as process reference surfaces; secondarily, finish milling is performed on two guide rail surfaces opposite to the process reference surface A; the center of the bottom plane of the X-shaped sliding block is used as the reference, and four process holes with equal diameters are machined in the positions, corresponding to the four X-shaped sliding block guide rails, of the bottom plane of the X-shaped sliding block and are used as auxiliary process references; the process reference surface A and the process reference surface B are used as references, and angles of 45-degree guide rail surfaces are controlled by the aid of an angle template and an angle gauge; process hinge pins are mounted in the four process holes, the size and position symmetry degrees of the four 45-degree guide rail surfaces are guaranteed, and finally, the X-shaped sliding block is rotated, and finish milling machining is performed on the 45-degree guide rail surfaces of the four X-shaped sliding block guide rails. The method has the advantages of being simple, convenient, accurate in positioning, simple to operate, high in machining precision and the like.

Description

Technical field: [0001] The invention relates to the technical field of guide rail processing, in particular to a method for processing an X-shaped slider guide rail. Background technique: [0002] In modern mechanical equipment, especially in mechanical pressure, X-shaped guide rails are used more and more, such as the application on forging press sliders with large tonnage and small table tops. The X-shaped guide rail has the advantages of long guiding length, large guiding contact area, high guiding precision, strong ability to withstand eccentric loads, and small inclination, especially in terms of guiding accuracy. Since the X-shaped guide rail is less affected by thermal expansion, it can be used in high-temperature production environments. Under this condition, it can effectively guarantee the fit clearance of the guide rail, ensure the guiding accuracy, and keep the accuracy of the processed workpiece unaffected. Although the X-shaped guide rail has the above advant...

Problems solved by technology

Although the X-shaped guide rail has the above advantages, the premise is that the machining accuracy of the X-shaped guide rail itself must be high, especially to ensure the symmetry requirements of each guide rail surface of the X-shaped guide rail. The existing X-shaped guide rail processing method is not only cumbersome, but also Machining accuracy is difficult to guarantee
