Abstract
The invention discloses a low-resistance compound type machine tool guide rail with high controllability. The low-resistance compound type machine tool guide rail comprises a track and a sliding block, wherein the track is of a long cylinder structure with the I-shaped cross section; a fixed bolt is arranged inside the track; ball bearings are arranged on the upper surface and side surfaces of the track; the sliding block is of a block structure with the T-shaped cross section; a groove is formed in the lower half of the sliding block; a part of the surface of the track, on which the ball bearings are arranged, is embedded in the groove; an assembly nut is arranged inside the sliding block; and a plastic sticking layer is arranged on the surface of the groove of the sliding block and is in tight contact with the ball bearings. The low-resistance compound type machine tool guide rail with high controllability has the beneficial effects that due to adoption of a ball and plastic sticking compound type structure, the controllability of accuracy of a relatively sliding position is also ensured while the low resistance is ensured, thereby ensuring the accuracy and stability of the machine tool in an operational process.
Description
Technical field
The present invention relates to machine tool guideway technical field, the compound machine tool guideway that particularly a kind of lower resistance controllability is high.
Background technology
Guide rail is a kind of structure member that supporting is moved along certain track with guided-moving component, and the movement locus of guide rail guiding can have straight line, circle or curve, and it is one of highly important parts in lathe.The machining accuracy of lathe and guide precision have and directly contact, and the precision machine tool of small lot batch manufacture, the labor content of guide rail accounts for about the 40% of whole machine tooling workload.Different level gauge face combinations, the friction constituted between rectangular guideway face is that sliding friction person is called rail plate, puts people's rolling element, make friction be changed into rolling friction person and be called rolling guide between guide pass.
Guide rail occupies important role in lathe work process, but machine tool guideway tends not to take into account in lower resistance and controllability two at present, affects the precision and stability of lathe work.
Summary of the invention
It is an object of the invention to as solving the problems of the prior art, it is provided that the compound machine tool guideway that a kind of lower resistance controllability is high.
For achieving the above object, the present invention proposes the compound machine tool guideway that a kind of lower resistance controllability is high, and including track and slide block, described track is the long column structure of i shaped cross section, portion is provided with gim peg in orbit, and upper surface and side surface at track are provided with ball bearing；Described slide block is the block structure in T font cross section, and the latter half of slide block is fluted, and raceway surface is provided with being partly embedded in groove of ball bearing；Slide block be internally provided with assembling nut, slip recess surface configuration has a laminating layer, described laminating layer and ball bearing close contact.
Wherein, described laminating layer material is politef.
Advantages of the present invention and having the benefit effect that
The present invention adopts ball and laminating composite structured, ensureing while lower resistance, it is ensured that the controllability of relative sliding position precision, it is ensured that lathe precision and stability in running.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is the cross section structure schematic diagram of the compound machine tool guideway that the present invention a kind of lower resistance controllability is high.
Fig. 2 is the top surface structure schematic diagram of the compound machine tool guideway that the present invention a kind of lower resistance controllability is high.
Fig. 3 is the side structure schematic diagram of the compound machine tool guideway that the present invention a kind of lower resistance controllability is high.
In figure: 1-track, 11-gim peg, 12-ball bearing, 2-slide block, 21-assemble nut, the laminating layer of 22-.
Detailed description of the invention
Consult Fig. 1,2,3, the compound machine tool guideway that the present invention a kind of lower resistance controllability is high, including track 1 and slide block 2, the described track 1 long column structure in i shaped cross section, being internally provided with gim peg 11 at track 1, upper surface and side surface at track 1 are provided with ball bearing 12；The described slide block 2 block structure in T font cross section, the latter half of slide block 2 is fluted, and track 1 surface is provided with being partly embedded in groove of ball bearing 12；Nut 21 is assembled in being internally provided with of slide block 2, and slide block 2 groove surfaces is provided with laminating layer 22, and laminating layer 22 material is politef, and described laminating layer 22 is in close contact with ball bearing 12.
When track 1 and slide block 2 relative sliding, owing to the existence of ball bearing 12 makes relative sliding resistance less, and the static and dynamic friction coefficient of laminating layer 22 is substantially close, it is ensured that slide and in static transformation process can control accuracy higher.
The above; it is only the present invention preferably detailed description of the invention; but protection scope of the present invention is not limited thereto; any those familiar with the art is in the technical scope that the invention discloses; it is equal to replacement according to technical scheme and inventive concept thereof or is changed, all should be encompassed within protection scope of the present invention.
