After the roller slider and the linear guide track are assembled, the roller sliders are accurately positioned relative to the linear guide track by virtue of the four-point contact between the rollers and the roller track bodies, and the roller sliders can perform high-speed low-noise motion in the axial direction of the guide track by virtue of the rolling motion of the rollers on the surface of the guide track.
Description
Technical field
The present invention relates to a kind of precision and move, be usually used in equipment manufacture, be particularly suitable for IT industry and industrial automation industry with adjustable clearance type quick roller guide rail.
Background technology
Mostly to be rolling element circulating for the line slideway of Shi Yonging in the market, because of its architectural characteristic decision, has following shortcoming:
1. rolling element can't seal, so often need filling lubricating oil to keep its wearability and low-friction coefficient;
2. in order to make a suitable movement clearance or pretightning force are arranged between slide block and the guide rail, can only in production technology, filter out a plurality of diameter grades to employed rolling element, determine the rolling element of a kind of diameter grade that each guide rail and slide block should use according to the real data of assembly, thereby increased the complexity of production management;
3. because the rolling element between slide block and the guide rail rolls along the guide rail direction, in order to reach the purpose of circulation, must be provided with backward channel, at the volley particularly in the high-speed motion, break-in place of continuous rolling element at the backward channel two ends can produce high-frequency percussion and make a noise and produce the reaction resistance, have a strong impact on service life simultaneously, therefore this guide rail is not suitable for high-speed motion.
Summary of the invention
The invention provides that the lighter aluminium alloy of a kind of operating weight and a small amount of special rolling-mill section be made, the quick roller guide rail of adjustable clearance.
Advantage of the present invention is:
1. used a large amount of light metals, overall weight has reduced 50～60% than generic linear guide rail, has reduced slide block inertia at the volley, helps high-speed motion.
2. the structure that adopts guide rail matrix and raceway body to separate makes processing technology quite simple.
3. the raceway body section is circular, contrasts other shape and has easy processing, output height, low cost and other advantages.
4. use roller to replace the circulating rolling body, the rolling element that is sealed in the roller is in the parcel of lubriation material all the time, can reach permanent lubricated effect.
5. rolling element moves in a circle, and has avoided motion to impact, and has alleviated motion noise, has improved service life.

Its specific embodiment:
A kind of adjustable clearance quick roller guide rail is made up of line slideway and roller slide block two large divisions.As shown in Figure 1, wherein the line slideway part is combined by guide rail matrix (112) and raceway body (113).Raceway body (113) directly is embedded in the groove (B101) of guide rail matrix (112) both sides, and after the location was correct, this featheredge of roll-in (B102) makes it distortion can hold raceway body (113) tightly.
As Fig. 1 b and shown in Figure 4, the roller Slipper is by slide body (121) and a plurality of roller (106), roller shaft (107), clearance adjusting screw (109) and straight pin (108), and end cap (115) and dust excluding plate (116) composition.In conjunction with Fig. 2 and Fig. 3, roller (106) is placed in the longitudinal fluting (B103) of slide body (121), roller shaft (107) along the vertical slotted hole (B104) of slide body (121) pack into vertical slotted hole (B104-1) and the interstitial hole (B107) that passes roller (106) roller (106) is fixing, pack into vertical slotted hole (B105) of slide body (121) of straight pin (108) blocks the clinoplain (B111) of roller shaft (107), makes it and can not withdraw from and rotate.A dust excluding plate (116) and end cap (115) are respectively installed in slide body (121) two ends, and straight pin (108) is blocked and is fixing.The clearance adjusting screw (109) of packing in the screwed hole (B106).
After roller slide block and the line slideway assembling, as Fig. 4, because roller shaft (107) has certain interval with vertical slotted hole (B104-1), rotary gap is adjusted screw (109), the taper seat (B109) of its lower end is contacted with the taper seat (B110) of roller shaft (107) upper end, promote roller shaft (107) to raceway body (113) near or leave, cooperate roller shaft (107) inclined-plane, lower end (B111) and different-diameter straight pin (108) effect, realize the setting of movement clearance or pretightning force.Screw (109) is loosening can use the fastening agent administration of fixed in order to prevent to adjust.So far, all rollers in the slide block and the guide pass of line slideway obtain even contact and do rolling, four arc surfaces (B108) of roller (106) that are positioned at the guide rail both sides with slide block four point locations in line slideway position accurately, and can bear from line slideway axis normal plane in the load force of all directions.
Because motion between roller and the guide rail and the motion between roller and the roller shaft are pure rolling friction; Rolling element in the roller can keep permanence lubricated because of sealed simultaneously; The movement locus of rolling element is a pure circle and can not produce any impulsive force and vibration; Overall weight has reduced 50～60% than generic linear guide rail in addition, and motional inertia is very little; The dust excluding plate (116) at slide body (121) two ends and end cap (115) can make each working face of line slideway clean all the time.
So the present invention has characteristics such as movement velocity height, motion noise are little, long service life.
