Abstract
The utility model discloses a sleeve structure of horizontal numeral control boring and milling machine, wherein a sleeve is arranged inside a fixed sleeve, the inner of the sleeve is a boring bar, a balancing sleeve is arranged between the sleeve and the fixed sleeve, the balancing sleeve is connected with the sleeve through double bonds, the double bonds are fixed on the sleeve through screws, both ends of the balancing sleeve are respectively provided with duplex bearings, and the duplex bearings are limited through bearing sleeves, and the bearing sleeves are sleeved on the external of the balancing sleeves. The sleeve structure has beneficial effects that the balancing sleeve is added, the function of finely tuning the shaft center is realized, the automatic center searching is realized during the operation process of the sleeve, simultaneously the vibration of a main shaft can be reduced, the moment inertia is increased, and the machining precision of boring and milling shaft is improved.
Description
Technical field
The utility model relates to a kind of sleeve barrel structure of horizontal type numerical control boring-milling machine, a kind of specifically tube-in-tube structure that is enclosed within on the horizontal digital-control boring-milling machine boring bar.
Background technology
At present, structure and design that the domestic boring and milling machine equipment of producing is adopted are still introduced from the Soviet Union decades ago.In this field, China does not have autonomous intellectual property fully.As a manufacturing powerhouse, need often to use boring and milling machine in fields such as machining, manufacturings.And the domestic employed high-end boring and milling machine equipment of present China generally all needs from external import.Because we can not produce the boring and milling machine equipment that satisfies domestic production processing needs ourselves, domestic relevant industry development often is limited by external technology like this.Particularly those and the closely bound up field of Defence business need to make high-precision product, have higher requirement for machining equipment.To this, grasp present state-of-the-art in the world technology in the present western developed country hand and having a large amount of intellectual properties, but in order to contain the development of rival and developing country, they are provided with numerous technology barriers for the outlet of these high-end devices.
Reform and open up to the outside world two during the last ten years, China constantly promotes the technical strength of oneself, has all obtained technological break-through and has obtained plentiful and substantial technological achievement in a lot of fields.But for the boring and milling machine apparatus field, by the end of so far, China patent total amount in disclosed this field is no more than 200, wherein at the patent quantity of horizontal boring and milling machine then still less.Simultaneously, we also can find through scrutinizing these disclosed patents, for these patent the insides, more are to carry out local improvement and design at existing boring and milling machine, can't break away from existing technological frame and carry out brand-new design.So up to now, China does not also have particularly horizontal boring and milling machine of boring and milling machine that ability produces complete independent intellectual property right.This is the common problem that the domestic boring and milling machine manufacturing enterprise of China is faced.
In sum, produce a kind of boring and milling machine of complete independent intellectual property right, not only can satisfy domestic production demand, break away from the technology barriers of western countries, also can promote technical research and the innovation of China simultaneously in this field to China.Designing the boring and milling machine of complete independent intellectual property right, is the development strategy needs that are based on whole country, also is the happiness of leaving we descendants for simultaneously.
The utility model is exactly the sleeve barrel structure of horizontal type numerical control boring-milling machine at complete autonomous Design, be enclosed within on the boring bar, with common tube-in-tube structure difference be on sleeve, to have supposed balance set.Adopt staircase structural model in the middle of the rack sleeve of traditional boring and milling machine equipment, bearing is installed at the two ends of step.This structure need be carried out twice processing for step in the process of processing can moulding, each first being processed all will be carried out rechuck with workpiece and be fixed, angle from operation, twice chucking installed the problem that is easy to occur axiality, very high to the required precision that adds man-hour, if the axle center difference of twice chucking installation all can produce very big influence so machining accuracy and the service life for whole equipment.
The utility model content
The purpose of this utility model provides a kind of sleeve barrel structure of horizontal type numerical control boring-milling machine, realizes the fine setting to the axle center, can make sleeve seek balance automatically in rotating process.
The purpose of this utility model is to be achieved through the following technical solutions:
Sleeve barrel structure of horizontal type numerical control boring-milling machine, sleeve are installed in fixed cover inside, and the inside of sleeve is boring bar, are provided with balance set between sleeve and fixed cover, and balance set is connected by two keys with sleeve, and two keys are screwed on sleeve; Two ends at balance set are respectively equipped with duplex bearing, and spacing by bearing holder (housing, cover) between the duplex bearing, described bearing holder (housing, cover) is enclosed within the outside of balance set.
The beneficial effects of the utility model are: set up balance set, have the effect that the axle center is finely tuned, make sleeve realize automatic searching center in the process of running, thereby reach balance and stable effect; Can reduce simultaneously the vibrations of main shaft, increase the rotary inertia of main shaft, improve the machining accuracy of boring and milling axle.
Description of drawings
With embodiment the utility model is described in further detail with reference to the accompanying drawings below.
Fig. 1 is slide block described in the utility model, boring bar figure;
Fig. 2 is an A place enlarged drawing among Fig. 1.
Among the figure
1, slide block; 2, boring bar; 3, tail pipe; 4, fixed cover; 5, sleeve; 6, balance set; 7, two keys; 8, bearing holder (housing, cover); 9, gear-box; 10, duplex bearing.
The specific embodiment
Horizontal digital-control boring-milling machine described in the utility model comprises lathe bed, big column, slide block 1, is installed in fixed cover 4 and gear-box 9 on the slide block 1.
With reference to figure 1, be the slide block 1 of horizontal digital-control boring-milling machine, the structure chart of boring bar 2, gear-box 9 is connected with motor, gear-box 9 is connected with tail pipe 3 simultaneously, the inside of fixed cover 4 is equipped with sleeve 5, inside at sleeve 5 and tail pipe 3 is equipped with boring bar 2, and motor drives boring bar 2 and sleeve 5 runnings simultaneously by the reduction gearing in the driven gear case 9.
With reference to figure 2, sleeve barrel structure of horizontal type numerical control boring-milling machine described in the utility model, sleeve 5 are installed in fixed cover 4 inside, the inside of sleeve 5 is boring bars 2, be provided with balance set between sleeve 5 and fixed cover 4, balance set 6 is connected by two keys 7 with sleeve 5, and two keys 7 are screwed on sleeve 5; Be respectively equipped with duplex bearing 10 at the two ends of balance set 6, spacing by bearing holder (housing, cover) 8 between the duplex bearing 10, described bearing holder (housing, cover) 8 is enclosed within the outside of balance set 6.
The rack sleeve structure of the above-mentioned design of process only needs once chucking to install and gets final product in the processing and manufacturing process, does not have the problem of axiality, can guarantee the precision of processing.
