Description

The Digit Control Machine Tool longitudinal feeding device
Technical field
The utility model belongs to the Digit Control Machine Tool equipment technical field, especially relates to a kind of Digit Control Machine Tool longitudinal feeding device.
Background technology
In the prior art; The Digit Control Machine Tool vertically general end that adopts of device is fixed; One end play adopts the butterfly spring pre-pressing structure, and it in use still exists ball-screw that the problems such as service life and kinematic accuracy of linearity, rotary inertia, amount of deflection, antero posterior axis bearing are installed.Vertically installing assembling at Digit Control Machine Tool generally is to be benchmark with the ball-screw nut seat, carries out centering ball-screw Up Highway UHW and side bus, and adjusting pad is joined at the bearing block place; Guarantee the axiality of antero posterior axis bearing dead eye, there is following defective in the method: it adopts the adjusting pad centering, can have the not enough problem of rigidity; And when assembling, often adjust by assembling; Guarantee the axiality between leading screw diaxon bearing and the screw bracket holes in that an adjusting pad must be installed between bearing block and the lathe bed faying face, this vertical Unit Installation and precision debugging be trouble very, repeatedly centering; Set-up time is long, and assembler's amount of labour is big.
Summary of the invention
The purpose of the utility model is exactly for solving the efficiency of assembling of existing Digit Control Machine Tool longitudinal feeding device; It is long that the centering time is installed in assembling; The defective that working strength of workers is big and design a kind of Digit Control Machine Tool longitudinal feeding device, thus the problem that exists in the prior art solved.
For realizing above-mentioned purpose; The technical scheme that the utility model adopts is: described Digit Control Machine Tool longitudinal feeding device; Comprise ball screw assembly, and lathe bed; Its characteristics are: described ball screw assembly, is installed on the lathe bed through front-end bearing pedestal and rear bearing block, and the ball-screw of ball screw assembly, is provided with spacer in the rear bearing block inboard, and the nut of ball screw assembly, links to each other with saddle through the nut support; The nut support links to each other with saddle with fixing pin through attachment screw, is provided with left adjusting pad and right adjusting pad between the both sides of nut support and the saddle.
Described front-end bearing pedestal and rear bearing block are fixedly linked through hold-down screw and shop bolt and lathe bed.
The beneficial effect that technique scheme exists is described Digit Control Machine Tool longitudinal feeding device, the bearing block of its different inner diameters; Ball-screw, structure of driving unit is united, parts around having simplified; Be optimized design; Weight reduction, stress analysis realizes the vertically modularized design of device of Digit Control Machine Tool.Its assembling adjustment accurately, and is convenient, the service life of having improved ball-screw.It reduces cost greatly, shortens processing, and assembling helps the time, has improved the transmission accuracy and the rigidity of ball-screw, and is easy to adjust, reduces working strength of workers simultaneously, enhances productivity.
Description of drawings:
Shown in Figure 1 is the Digit Control Machine Tool longitudinal feeding device structural representation of the utility model.
Among the figure: 1-front-end bearing pedestal, 2-hold-down screw, 3-shop bolt, 4-lathe bed, 5-ball-screw, 6-left side adjusting pad, 7-attachment screw, 8-saddle, 9-nut, 10-nut support, the right adjusting pad of 11-, 12-spacer, 13-fixing pin, 14-rear bearing block.
The specific embodiment
From shown in Figure 1; Described Digit Control Machine Tool longitudinal feeding device; Comprise ball screw assembly, and lathe bed 4; Its characteristics are: described ball screw assembly, is installed on the lathe bed 4 through front-end bearing pedestal 1 and rear bearing block 14, and the ball-screw 5 of ball screw assembly, is provided with spacer 12 in rear bearing block 14 inboards, and the nut 9 of ball screw assembly, links to each other with saddle 8 through nut support 10; Nut support 10 links to each other with saddle 8 with fixing pin 13 through attachment screw 7, is provided with left adjusting pad 6 and right adjusting pad 11 between the both sides of nut support 10 and the saddle 8.
Described front-end bearing pedestal 1 is fixedly linked through hold-down screw 2 and shop bolt 3 and lathe bed 4 with rear bearing block 14.
Described Digit Control Machine Tool longitudinal feeding device, its when mounted, with installation base surface and the installing and locating face of front-end bearing pedestal 1, with hold-down screw 2 fastening front-end bearing pedestals 1 near lathe bed 4; Saddle 8 is placed on lathe bed 4 front ends, and nut support 10 is installed and is fastened on saddle 8 lower end faying faces with attachment screw 7, and middle left adjusting pad 6 and the right adjusting pad 11 placed imports ball-screw 5 into nut support 10; Swing roller leading screw 5 imports in the front-end bearing pedestal 1 ball-screw into, with round nut pretension front-end bearing pedestal 1; Continue swing roller leading screw 5, nut 9 and nut support 10 faying faces are suited, with screw that ball-screw 5 and nut support 10 is fastening; Import spacer 12, rear bearing block 14 into ball-screw, fastening with hold-down screw 2, unclamp attachment screw 7 a little; Remove left adjusting pad 6 and right adjusting pad 11, detect adjusting pad actual numerical value, swing roller leading screw 5 with gauge block; The nut support is moved to rear bearing block 13 places along bed ways, detect the adjusting pad actual numerical value, join actual adjusting pad with gauge block; Be fastenedly connected screw 7, the shop bolt 3 on fastening front-end bearing pedestal 1 and the rear bearing block 14, and the fixing pin on the nut support 10 13.
Described Digit Control Machine Tool longitudinal feeding device; Its antero posterior axis bearing adopts the boring technology of closing, the axiality of diaxon bearing before and after guaranteeing, and dead eye is to the uniformity of installation base surface with location basal plane dimensional tolerance; Lathe bed go forward rear bearing block installation base surface and locating surface coplane; Therefore, during installation with the antero posterior axis bearing near the lathe bed basal plane, so realize the vertically installation of device ball-screw very easily; Not be used in and detect the Up Highway UHW of ball-screw and beating of side bus, measure to detect and join adjusting pad.
