Abstract
The utility model discloses a main shaft driving mechanism of horizontal numeral control boring and milling machine, which comprises a slide block and a gear box arranged on the slide block, wherein the gear box is connected with the motor, simultaneously the gear box is connected with a tail cylinder, a sleeve is arranged inside a fixed sleeve, a boring bar is respectively arranged inside the sleeve and the tail cylinder, a gear sleeve is arranged on the boring bar, the gear sleeve is connected with a main driving gear, the main driving gear drives the boring bar to rotate through a bearing sleeve, the main driving gear is engaged with a driving gear of the gear box, the main driving gear is simultaneously connected with an inner gear and is fixed, and the inner gear realizes driving the sleeve through engaging with an external gear on the sleeve. The driving mechanism has beneficial effects that a simple structure is adopted to realize simultaneously driving the boring bar and the sleeve by the gear box, the whole mechanism adopts the boring bar to be as a common shaft, which does not need an external designed shaft to support the driving, thereby reducing the dimension of the driving mechanism and the occupied space, and enabling the structure layout to be more reasonable.
Description
Technical field
The utility model relates to a kind of horizontal digital-control boring-milling machine, specifically a kind of main shaft spindle drive of horizontal digital-control boring-milling machine.
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 spindle drive of the horizontal digital-control boring-milling machine of complete autonomous Design.
The utility model content
The purpose of this utility model provides a kind of main shaft transmission mechanism of horizontal type numerical control boring-milling machine, adopts relative simple mechanism to realize transmission boring bar and sleeve simultaneously.
The purpose of this utility model is to be achieved through the following technical solutions:

Fig. 2 is an A place partial enlarged drawing among Fig. 1.
Among the figure:
1, slide block; 2, gear-box; 3, motor; 4, tail pipe; 5, sleeve; 6, fixed cover; 7, boring bar; 8, main drive gear; 9, geared sleeve; 10, internal gear; 11, external gear.
The specific embodiment
As shown in Figure 1, main shaft transmission mechanism of horizontal type numerical control boring-milling machine described in the utility model, comprise slide block 1, be installed in the gear-box 2 on the slide block 1, gear-box 2 is connected with motor 3, gear-box 2 is connected with tail pipe 4 simultaneously, the inside of fixed cover 6 is equipped with sleeve 5, inside at sleeve 5 and tail pipe 4 is equipped with boring bar 7, geared sleeve 9 is installed on boring bar 7, geared sleeve 9 is connected with main drive gear 8, main drive gear 8 drives boring bar 7 by geared sleeve 9 and rotates, main drive gear 8 meshes with the travelling gear of gear-box 2, main drive gear 8 is connected with an internal gear 10 simultaneously and is fixing, and internal gear 10 meshes the transmission that realizes sleeve 5 with the external gear 11 that is fixed on the sleeve 5.
The beneficial effects of the utility model are: adopt a simple structure to realize that gear-box is simultaneously to boring bar With the transmission of sleeve, whole mechanism adopts boring bar as common axis, does not need the axle of additional designs to support biography Moving, reduced the size of transmission mechanism and shared space, make topology layout more reasonable.
