Abstract
The utility model relates to a tailstock with adjustable height of the centre. A tailstock body with adjustable height and a pedestal are adopted; the working performance and the structure of a lathe are further perfected; contour height errors of two centers can be reliably and conveniently adjusted randomly; the machining quality of workpieces in each period of the entire service life of a lathe can be guaranteed. The utility model changes the time consuming and labour consuming processing form for repetitious correction and measurement caused by abrasion after the installation of the original lathe, reduces the cost of production and maintenance, shortens the period, and enhances the aggregate production rate.
Description
The utility model relates to the adjustable tail stock of a kind of pitch of centers.
At present, the domestic and international lathe of making, its tailstock centre centre-height is the fixed pattern structure, after new machine comes into operation, because the relative motion of tailstock floor rails and bed piece end face composite guideway face, promptly can produce wearing and tearing, along with the operating period increases, its wearing and tearing are expansion day by day also, because of wear extent increases the original precision of the relative complete machine of tailstock will be lost gradually, produced tailstock taper hole sleeve axis and head of a bed main-shaft axis etc. high level error, thereby processed product precision can not be guaranteed.
The purpose of this utility model is development a kind of top centre-height adjustable tail stock, can revise high level errors such as tailstock and the head of a bed two be top at any time.
Technical solution of the present utility model is: the adjustable tail stock of top centre-height comprises that inclined end face tailstock body, inclined-plane base, holding screw are paid, base, guide rail latch segment, adjusts screw, standard screws, waist shape fastener hole.It is characterized in that, inclined end face tailstock body bottom surface is manufactured to the tilt inclined-plane of a sinusoidal angle of head of a bed direction, keep intact in the bottom surface of inclined-plane base, it is identical with inclined end face tailstock body bottom surface gradient that end face manufactures, the inclined-plane that direction is relative, there is a boss at the inclined end face center of tailstock body, there is a recessed frame at the oblique top face center of base, when tailstock body and base assembling, locate in recessed frame with boss, in a side of inclined-plane base 2 screw holes in the recessed frame of break-through are arranged, pay a side tightening with 2 holding screws with tailstock body bottom surface boss, the bottom surface boss is installed in single face location in the recessed frame at the bottom of reaching tailstock, the recessed frame internal thread hole of one break-through is respectively arranged in vertical rear and front end of inclined-plane base, and promptly available holding screw tightening tailstock body boss is two sides longitudinally, can play corrective action to the front and back tense-lax again.On the relevant position in inclined-plane base two outsides, install and adjust screw, be used to adjust the lateral attitude of tailstock centre.Four waist shape fastener holes are arranged on the inclined end face tailstock body, this hole is promptly as tailstock body and the fastening hole of inclined-plane base, can be used as the hole of the displacement of adjusting the tailstock height again, the relative displacement on two inclined-planes by inclined-plane base and inclined end face tailstock body can realize the adjustment of tailstock taper hole sleeve axis in short transverse.Four screwed holes are arranged on the inclined-plane base, pay with four standard screws and to pass four waist shape fastener holes, tailstock body and base are fastened as one, its fastening force is greater than the coupling mechanism force of tailstock assembly and bed ways, remains unchanged with the parallel of bed ways during with the lift adjustment of assurance taper hole sleeve axis.
It is further perfect that the utility model obtains service behaviour, the structure of lathe, can be at any time in application, adjust and eliminate two high level errors such as top reliably, guaranteed the crudy of workpiece in lathe whole useful life period in each stage, also improve former lathe manufacturing and general overhaul and need revise, measure, consume worker's operation form consuming time when mounted repeatedly, reduced and made and the production cost of repairing, shorten the cycle, improved aggregate production rate.

Fig. 2 is the left pseudosection of the adjustable tail stock of a kind of top centre-height;
Fig. 3 is the vertical view of the adjustable tail stock of a kind of top centre-height;
Fig. 4 is that the bolt structure schematic diagram is adjusted in base both sides, inclined-plane.
Below in conjunction with accompanying drawing the utility model is described in further detail:
By accompanying drawing as can be known, the adjustable tail stock of a kind of top centre-height is made of inclined end face tailstock body 1, inclined-plane base 2, base 3, guide rail latch segment 4, waist shape fastener hole 5, adjustment screw 6, square toes screw rod 7, lock nut 10, holding screw 11.When making tailstock body 1, tailstock body 1 is processed into the inclined end face of bottom surface to a sinusoidal angle of head of a bed direction inclination, base 2 end faces are processed into identical with tailstock body 1 inclined end face gradient, the oblique top face that direction is relative, at boss of tailstock body 1 inclined end face center processing, the end face of inclined-plane base 2 adds a recessed frame, when inclined end face tailstock body 1 assembles with inclined-plane base 2, boss plays the role of positioning in recessed frame, on the relevant position, two outsides of inclined-plane base 2, be equipped with and adjust screw 6, in order to adjust the lateral attitude of tailstock centre, at two screwed holes of a side of inclined-plane base 2 processing, in the recessed frame of screwed hole break-through, pay 8 sides of ending tight inclined end face tailstock body 1 bottom surface boss with two holding screws, reach boss single face location in recessed frame, respectively process a screwed hole in the recessed frame of break-through in vertical rear and front end of inclined-plane base 2, pay in the recessed frame of 9 break-through tightening tailstock body inclined end face boss two sides longitudinally with holding screw, and can before and after the degree of tightness adjustment tailstock body is vertically moved.Four waist shape fastener holes 5 of processing on inclined end face tailstock body 1, four screwed holes of processing are connected as a single entity inclined-plane base 2 and inclined end face tailstock body 1 with four standard screws 11 on inclined-plane base 2, and waist shape fastener hole 5 also is the hole of adjusting the displacement of tailstock height.Pass guide rail latch segment 4, base 3, inclined-plane base 2 and inclined end face tailstock body 1 with square toes screw rod 7, use lock nut 10 its locking.
