This traditional protection mode has all limitation.Because this telescopic protective cover is installed in down the front end of planker, between following planker and tail stock for machine tool body, and following planker and tailstock body have relative motion, and protective cover need be avoided tailstock body, so the installing space of protective cover is very little; Because of X is far longer than protective cover installing space size (2-3 being arranged usually doubly) to stroke, protective cover is forced to be designed to inside and outside stacked which floor structure well; Have in order to reduce stacked quantity, increase the protective cover installing space, specially mill off tailstock body and protective cover that some of interfering is a cost with weakening tailstock rigidity like this, this is an one.
Its two, stacked protective cover is limit because of structure, lacks retractility flexibly, influences X greatly to fast feed speed and response characteristic.
Its three, stacked protective cover stretching bonnet has reduced lathe this major parameter of " crossing the planker maximum turning diameter " above following planker.
How to improve X to the planker safeguard structure, overcome the limitation of traditional stacked protective cover, research and development starting point of the present utility model that Here it is.
Summary of the invention
The purpose of this utility model provides and a kind ofly can realize the protector of X to linear rolling track and ball-screw simply, reliably, easily, this device can not interfered with tailstock body, can not influence X to fast feed speed and response characteristic and this major parameter of lathe " planker maximum turning diameter excessively " yet.
This X comprises and scrapes bits plate, cover plate, big briquetting and side scraper plate to linear rolling track and ball-screw protector; Last planker front end is equipped with scrapes the bits plate; On the middle pit of following planker cover plate is housed; The line slideway sidepiece is equipped with big briquetting, and big briquetting is connected with following planker; The lower surface of scraping the bits plate becomes sliding-contact with the cross section of big briquetting end face, cover plate upper surface and line slideway; The side scraper plate is connected the planker both sides, and the medial surface of side scraper plate becomes sliding-contact with the lateral surface of large plate.
Operation principle of the present utility model is: in X planker cutting region up and down, by big briquetting and cover plate simple structure, regular planar, easily reach and scrape the bits purpose thereby make the side scraper plate and scrape the bits plate.
Beneficial effect: the utility model compared with prior art, its advantage is that the structure of protector is simplified greatly, make this device with simple, mode realizes scraping the bits protection reliably.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing.
The utility model comprises fixing planker 1 down, line slideway 2, slide block 3, goes up planker 4, little pressing plate 5, big briquetting 6, side scraper plate 7, end plate 8, scrapes bits plate 9, cover plate 10, bearing block 11, feed screw nut seat 12, ball-screw 13.
Two line slideways 2 are fixed on the fixing planker 1 down by screw, and four slide blocks 3 are in motion on line slideway 2 in twos respectively, and four slide blocks 3 are fixed on the planker 4 by screw, and last planker can move to the line slideway direction along X under leading screw drives; Two line slideway 2 outsides are pressed on down on the guide rail erecting bed terrace of planker by little pressing plate 5 and big briquetting 6 respectively.Side scraper plate 7 is fixed on fixing planker 4 both sides of going up by screw.Last planker 4 front ends are equipped with end plate 8, scrape bits plate 9 and are screwed on end plate 8.
