Abstract
Disclosed is a combined rolling and sliding lead rail for a machine tool. The lower part of the lead rail is a steel plated guideway; rolling slide blocks, a rolling slide block seat and a support plate are arranged from left to right on the upside of the steel plated guideway; the steel plated guideway is fixed on the rolling slide block seat and the support plate respectively through hexagonal fastening socket head bolts; and a polytetrafluoroethylene lead rail soft belt is affixed on the face of the lead rail between the two rolling slide blocks. The combined rolling and sliding lead rail of the machine tool improves the precision and the machining efficiency of the machine tool and meanwhile improves the rigidity and the bearing capacity of the machine tool and prolongs the service life of the machine tool.
Description
Affiliated technical field
The utility model relates to a kind of track-type facilities, and especially lathe rolls, slides the composite guideway device.
Background technology
At present, in the track-type facilities of lathe, prior art is the track-type facilities that the track-type facilities combined of rail plate pair and linear rolling guide are combined, the secondary employing of rail plate stickup coefficient of friction on slide guide rail is little, the soft PTFE ribbon of long service life, thereby it is strong to make guide rail reach bearing capacity, frictional force is little, the track-type facilities of long service life; Linear rolling guide then adopts rolling slide block to move on rolling linear guide, and the rolling by ball in the rolling slide block changes sliding friction into rolling friction, greatly reduces the frictional force of guide rail, and then has improved the kinematic accuracy and the speed of guide rail.
No matter be that simple rail plate pair or simple linear rolling guide all obviously exists deficiency, the secondary translational speed of rail plate is slow, precision is low, occurs creeping phenomenon when low speed sometimes; The linear rolling guide loaded area is little, and rigidity is secondary strong not as rail plate.
Summary of the invention
In order to solve the problem that exists in the existing slideway auxiliary device, particularly horizontally mill in heavy type, in the boring machining center, should guarantee efficient and precision that lathe is higher, guarantee rigidity intensity and bearing capacity that lathe is enough again, so that can guarantee the machining accuracy and the efficient of lathe.The utility model provides a kind of lathe to roll, has slided the composite guideway device, and it has the advantage of sliding friction pair and two kinds of guideways of rolling friction pair concurrently, has both guaranteed that lathe had higher precision and efficient, has strengthened the rigidity and the bearing capacity of lathe again.
The technical scheme that its technical problem that solves the utility model adopts is: lathe rolls, sliding composite guideway device, its bottom is a steel guideway, be rolling slide block, rolling slide block seat, supporting plate successively about above the steel guideway, be fixed on rolling slide block seat and the supporting plate with interior hexagonal trip bolt respectively, on pallet guide face between two rolling slide blocks, be pasted with the polytetrafluoroethylene (PTFE) guide-soft-band.
Lathe rolls, sliding composite guideway device, the bottom is the steel guideway through high-frequency quenching, accurate grinding, steel guideway is installed on the lathe bed of various lathes, it on steel guideway the pallet guide faying face, the two ends of pallet guide faying face are equipped with high rigidity, high-accuracy rolling slide block, the centre is the rail plate that is pasted with the polytetrafluoroethylene (PTFE) guide-soft-band, by suitable processing technology and sufficient scraping to slide guide rail; The rolling slide block and the middle slide guide rail that guarantee two ends on the supporting plate all can organically engage with steel guideway, and lathe rolls, sliding composite guideway device thereby form.
The high-frequency quenching steel guideway, high rigidity, high-accuracy rolling slide block and be pasted with the rail plate of polytetrafluoroethylene (PTFE) guide-soft-band have guaranteed that lathe has higher precision and efficient, have strengthened the rigidity and the bearing capacity of lathe.
The beneficial effects of the utility model are, steel guideway by high-frequency quenching, high rigidity, high-accuracy rolling slide block and be pasted with the application of the rail plate of polytetrafluoroethylene (PTFE) guide rail band, the precision and the working (machining) efficiency of lathe had both been improved, strengthen simultaneously the rigidity and the bearing capacity of lathe again, prolonged the service life of lathe.
