Abstract
The utility model relates to the novel structure of a machine guide track, formed by that a split guide track basal plane and a wear-resistant guide track corresponding to a sliding plane of a tool carriage are combined. The wear-resistant guide track comprises a machine body wear-resistant guide track and a tool carriage wear-resistant guide track; the machine body wear-resistant guide track presents a ladder structure; the tool carriage wear-resistant guide track is composed of the bottom surface of a dovetail groove and a dovetail block which are nutually fixed. The utility model improves the traditional integral guide track into the split combined guide track basal plane and the wear-resistant guide track; the wear-resistant guide track is made of specified material which can be conducted with quenching heat treatment so as to improve the wearability and the service life of the machine guide track and guarantee the machining precision of products.
Description
The utility model relates to the machine tool guideway structure.
Machine tool guideway comprises bed ways and carriage rail, it is the benchmark architecture of planker (comprising saddle, middle carriage, upper slide rest) sliding motion, traditional machine tool guideway all adopts the cast iron manufacturing, on metal-planing machine, be processed into the guide rail shape after the iron casting moulding, and then carrying out blademan's skill, the cast iron guide rail is not wear-resisting, the life-span short.In order to improve the service life of guide rail, change the cast iron guide rail of last ton weight into the cast steel guide rail, purpose is to handle in order to carry out surface heat to the cast steel guide rail, improve the wearability of guide rail with this, but adopt the cast steel guide rail will change expensive cost, the cost of material that at first is foundry goods improves greatly, because bulky heat treated difficulty is also very big, leaveing no choice but that large-scale high frequency heat treatment facility solves can not, so neither optimal behave, and in fact present cast steel guide rail especially dovetail guide be difficult for machined after because of heat treatment, therefore all do not do heat treatment, just wearing and tearing influence processing precision of products and service life after work a period of time.
The purpose of this utility model provides a kind of structure with the split combination to replace former overall structure, the machine tool guideway new construction that wearability is good to reach, the life-span prolongs with regard to being to avoid the defective of prior art.
According to above-mentioned purpose, embodiment of the present utility model is: this machine tool guideway new construction, comprise the guide rail basal plane, bed ways basal plane and carriage rail basal plane are arranged, it is characterized in that compound wear-resisting guide rail fixing with it, that match with the planker sliding surface on the described guide rail basal plane.
Described wear-resisting guide rail is the trapezoidal wear-resisting guide rail of lathe bed.
Described wear-resisting guide rail is the wear-resisting guide rail of swallow-tailed planker, is made up of dovetail groove bottom surface and dovetails fastened to each other.
The utility model is improved to the structural shape of split combination to traditional integrated guide rail, both can adopt wearability material making preferably, the Technology for Heating Processing that can carry out necessity again changes the mechanical performance of guide rail, the wearability and the service life of machine tool guideway are further improved, guarantee processing precision of products.
The utility model has following accompanying drawing.
Fig. 1 is the location drawing of the utility model in machine tool structure.
Fig. 2 is the A-A cutaway view (the wear-resisting guide rail structure of lathe bed) of Fig. 1.
Fig. 3 is the B-B cutaway view (the wear-resisting guide rail structure of planker) of Fig. 1.
Below will the utility model is described in further detail by above-mentioned accompanying drawing embodiment.
As Figure 1-3, the machine tool guideway new construction is by the guide rail basal plane of minute bluk recombination and fastened to each other the forming of wear-resisting guide rail that matches with the planker sliding surface.Described guide rail basal plane all adopts the plane structure of being convenient to process.
Guide rail basal plane in the lathe has bed ways basal plane (1), carriage rail basal plane (3), and the carriage rail basal plane comprises saddle guide rail basal plane, middle carriage guide rail basal plane.
Wear-resisting guide rail has wear-resisting guide rail of lathe bed (2) and the wear-resisting guide rail of planker, and the wear-resisting guide rail of planker comprises the wear-resisting guide rail of saddle, the wear-resisting guide rail of middle carriage and the wear-resisting guide rail of upper slide rest.The wear-resisting guide rail of lathe bed is trapezium structure, and the wear-resisting guide rail of planker is the dovetail shaped structure, and is made up of dovetail groove bottom surface (4) fastened to each other and dovetails (5).
Wear-resisting guide rail can adopt bearing steel or high-carbon steel or pinion steel or spheroidal graphite cast-iron to make.
Wear-resisting guide rail is during as the wear-resisting guide rail of lathe bed (2), and after general machineds such as boring, tapping, can heat-treat quenches improves hardness, with it and guide rail basal plane fixing after, can carry out grinding, the raising precision.
Wear-resisting guide rail needs can heat-treat quenching after machineds such as general boring, tapping to dovetail groove bottom surface (4) and dovetails (5) during as the wear-resisting guide rail of planker, and the dovetail groove bottom surface can embed in the planker groove, carries out grinding after fixing.Will be equally processing after quench, dovetails and dovetail groove bottom surface and the fastening one of carriage rail basal plane three after the grinding, generally needn't do to shovel and scrape processing, scrape processing and the dovetail groove of the planker that matches with them such as middle carriage and upper slide rest shoveled.Since compound after can carrying out the wear-resisting guide rail of quenching heat treatment on traditional cast iron machine tool guideway, the wearability of guide rail and service life are improved greatly, help improving the machining accuracy of product.
Claims (4)
1. a machine tool guideway new construction comprises the guide rail basal plane, and bed ways basal plane (1) and carriage rail basal plane (3) are arranged, and it is characterized in that being compounded with on the described guide rail basal plane wear-resisting guide rail fixing with it, that match with the planker sliding surface.
