Description

Drop height type plane slide rail

The utility model relates to lathe equipments, relates in particular to a kind of drop height type plane slide rail.

Consult Fig. 1, shown in Figure 3, the lathe ramp design of commonly using (referring to that especially CNC controls lathe automatically), mainly be to be provided with two types rail structure at lathe bed 40, be straight formula slide rail 30 and tilted back type slide rail 20, the chuck 60 of its both lathe beds 40 1 sides is widely used technology, so describe in detail no longer especially.

Consult shown in Figure 2, wherein straight formula slide rail 30 is the rail structure of early using, mainly with parallel contour projection of twice and the slide rail 30 that forms perpendicular to lathe bed 40 end faces, and on two parallel contour slide rails 30, be provided with a saddle 50 that cooperates with it, wherein saddle 50 belows offer the slideway 503 of inserting and supply slippage for straight formula slide rail 30, make saddle 50 can be on slide rail 30 slippage uniformly, its both sides all connect the dust cover 70 that ladder heap is built or put on display, utilize both sides dust cover 70 flexible slide rail 30 tops that cover, make that smear metal is unlikely drops on slide rail 30, and cause the stuck of 503 in slide rail 30 and slideway or damage, saddle on 50 by its set motor 52 drive cutter towers 51 and on saddle 50, vertically process moving of object route, to finish whole processing action.

But this straight formula slide rail 30 is during with saddle 50 actions, though the strength that imposes on slide rail 30 because of saddle 50 is evenly to drop on the parallel contact-making surface, so the overall wear amount is little, and the precision height, can also can produce following shortcoming: 1, dust cover easily blocks bits.Parallel design because of straight formula slide rail 30, make the saddle 50 on it also be parallel to lathe bed 40, this moment, the dust cover 70 of both sides also was a parastate, like this, the smear metal that adds the ejection in man-hour is just dropped on the ladder telescopic joint of dust cover 70, long-term accumulation very easily causes dust cover 70 Integrated Chips, causes the not state and the generation other problems of easy to clean.2, the saddle top surface area takes up space many.Because the parallel design of straight formula slide rail 30 also is parallel on the lathe bed 40 saddle 50, so the width of saddle 50 end faces must be provided with than large tracts of land, will occupy than large space like this.

Consult Fig. 3, shown in Figure 4, design shortcoming at straight formula slide rail 30, the practitioner of the sector develops tilted back type slide rail 20, mainly be to utilize twice slide rail 20 end faces in the height end faces design of same 30 degree on the parallaxs, make saddle 50 bottom surfaces be height end faces that 30 degree tilt and design that two slideways 502 are inserted slide rail 20 and form obliquity to be parallel to slide rail 20; And saddle 50 is identical with aforementioned means, the cutter tower 51 of cutting tool is installed and drives motor 52, and both sides connect the dust cover 70 of inclined design.The molar behavior stroke is to utilize the inclined design of saddle 50 by tilted back type slide rail 20, make saddle 50 with straight formula slide rail 30 in the size of same size, by the angle of inclination of tilted back type slide rail 20, be less than the effect of straight formula slide rail 30 areas occupied, finish identical cutting stroke; Because dust cover 70 also is an inclined design, when making smear metal fall thereon, can take advantage of a situation and drop lathe bed 40 times, can not produce card bits situation, the inclined design of saddle 50 makes the cutter tower 51 on it also be an inclination angle state, and at this moment its weight just derives two component, when one component acted on the processing object, proper and Tool in Cutting power was offset; And another component drops on the vertical direction of 50 of saddles, so the stability of cutter tower 51 cuttings also is better than the design of straight formula slide rail 30.

But, the inclined design of tilted back type slide rail 20 end faces, during actual the use also not as the ideal of expection, and the following critical defect of can deriving: such as the slide rail unbalance stress.Commonly use tilted back type slide rail 20 and be designed to a sloped top face body, so when the slideway 502 of saddle 50 during at slide rail 20 top offsets, the weight of whole saddle 50 and installing on it and frictional resistance all result from the upper end oblique angle place of slideway 502 against 20 conflicts of twice slide rail, cause two slide rails 20 narrow and small because of the lifting surface area of this position, place, and cause the pressure maximum of unit are, the wear extent that produces is also maximum, the position, following oblique angle that slide rail 20 contacts with slideway 502, then, asellate 50 weight do not have any burden because of compressing, overall structure is in long displacement, after the friction, upper end drift angle support place in its slideway 502 just produces serious gap because of wearing away for a long time with slide rail 20, makes saddle 50 produce the situation that moves down; But at this moment to calculate the numerical value of each be starting point with 0 still to computer, so the precision of processing object just produces the deviation of calculating with actual, add that both gaps constantly enlarge because of the wearing and tearing that continue, to adding required processing object and the saddle 50 of bearing very big torsion in man-hour, just can produce abnormal vibrations, like this, very big to the destructiveness of lathe body and processing object.

In view of this, the exploitation of this creator active research by means of the experience of lathe design for many years, through long-term endeavour, is finished design of the present utility model finally.

The purpose of this utility model is to provide a kind of drop height type plane slide rail, it is designed to the drop run-in index with the slide rail end face, make the saddle of carrying cutter on slide rail, carry out machining position when moving, stressed even, reduce wearing and tearing, and the precision height of processing object, the chip removal performance of dust cover is good, and prolong service life.
