Description
Technical field
This utility model relates to the dynamical system of numerically controlled lathe, particularly a kind of ER axle power set.
Background technology
The power set of existing numerically controlled lathe, mainly the shell by main shaft (being commonly called as ER axle) with for supports main shaft forms, the bearing at two ends is only leaned on to support firm between its main shaft and fixing shell, this structure is in running, due to sub-power axle be from the side with main shaft engaged transmission, very big side can be caused impulse force to main shaft, when only having bearings at both ends and supporting, main shaft mid portion with in sub-power through-drive process, to under the effect to impulse force of the side of main shaft, the mid portion of main shaft is just easy to produce flexural deformation and abrasion, dynamical system is easily damaged aging.And the power set of existing numerically controlled lathe, the inside of its fixing shell is the cavity of complete hollow, although this structure is easily worked, but, because being hollow, the mid portion of main shaft can not get any support, also leads to main shaft and is easily bent by side force effect and damages.Therefore, carry out redesigning accordingly and improving to the power set of existing numerically controlled lathe, be highly desirable to.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model is in that to provide the mid portion of a kind of main shaft to be not easy to produce flexural deformation and abrasion, dynamical system are not easy to damage the ER axle power set that aging, longer service life, operation are more stable.
nullThis utility model solves the technical scheme is that ER axle power set of its technical problem，Including fixing housing、Run through the driving shaft of whole fixing housing from top to bottom、Intersected with each other and be respectively arranged at mutual vertically fixing housing two sides first、Two row transfer axles，Described first、In two row transfer axles, two transfer axles that are often adjacent and that be arranged in a mutually vertical manner constitute one group，Two transfer axle tops of every component moving axis are designed with transfer helical gear，And the transfer helical gear of every component moving axis is all corresponding to one group of active oblique gear engaged transmission on driving shaft，The helical teeth of two active oblique gears often organizing active oblique gear is in opposite direction，Described fixing housing upper、Lower both ends are respectively equipped with、Bottom end bearing，Described driving shaft is interspersed to be fixed on、Between bottom end bearing，Described driving shaft is positioned at、At least one intermediate bearing it is additionally provided with between bottom end bearing，Described intermediate bearing is between two groups of active oblique gears that the dynamic helical gear of every two components is corresponding，Described intermediate bearing is fixed on the inside of fixing housing.
Concrete, described intermediate bearing and upper and lower end coaxial bearing.
Concrete, described active oblique gear and transfer helical gear are 45 degree of helical gears.
Concrete, described intermediate bearing is fixedly mounted in the bearing cross hole in set casing body.
Concrete, described first and second row transfer the tip of the axis is equipped with tool holding device.
The beneficial effects of the utility model are: owing to being positioned on described driving shaft, at least one intermediate bearing it is additionally provided with between bottom end bearing, described intermediate bearing is between two groups of active oblique gears that the dynamic helical gear of every two components is corresponding, described intermediate bearing is fixed on the inside of fixing housing, so main shaft with in transfer through-drive process, on not only having, the support of lower bearings at both ends, and side impulse force can be supported by intermediate bearing of main shaft is offset by transfer axle, the mid portion of main shaft would not produce flexural deformation and abrasion, dynamical system is made to be not easy damage aging；Owing to described intermediate bearing is fixedly mounted in the bearing cross hole in set casing body, the inside of fixing housing is bearing cross hole, rather than the cavity of hollow, bearing cross hole supports intermediate bearing, thus the mid portion of supports main shaft, it is possible to offset the side force effect that main shaft is subject to, make main shaft be not easy bending and damage, ensure that the lathe dynamical system of high-quality, make lathe dynamical system longer service life.
Accompanying drawing explanation
Below in conjunction with drawings and embodiments, the utility model is described in further detail.
Fig. 1 is schematic appearance of the present utility model.

Detailed description of the invention
nullWith reference to Fig. 1、Fig. 2、Fig. 3，This utility model ER axle power set，Including fixing housing 1、Run through the driving shaft 2 of whole fixing housing from top to bottom、Intersected with each other and be respectively arranged at mutual vertically fixing housing two sides first、Two row transfer axles 3、4，Described first、In two row transfer axles, two transfer axles that are often adjacent and that be arranged in a mutually vertical manner constitute one group，Two transfer axle tops of every component moving axis are designed with transfer helical gear 5，And the transfer helical gear of every component moving axis is all corresponding to one group of active oblique gear 6 engaged transmission on driving shaft，The helical teeth of two active oblique gears often organizing active oblique gear 6 is in opposite direction，Namely one positive one anti-，So，Its helical teeth lines is orthogonal，Thus two transfer axles of every component moving axis are also arranged in a mutually vertical manner，Described fixing housing upper、Lower both ends are respectively equipped with、Bottom end bearing 7、8，Described driving shaft is interspersed to be fixed on、Between bottom end bearing，Described driving shaft is positioned at、At least one intermediate bearing 9 it is additionally provided with between bottom end bearing，Described intermediate bearing is between two groups of active oblique gears that the dynamic helical gear of every two components is corresponding，Described intermediate bearing is fixed on the inside of fixing housing.At least one intermediate bearing, for the mid portion of supports main shaft, is used for the counteracting transmission from side to impulse force.
Concrete, described intermediate bearing is with upper, bottom end bearing is coaxial, to ensure the stability of spindle drive, in the prior art, on only having, bottom end bearing, namely two bearings are only had, so accomplishing is coaxially easily, under normal circumstances, technical staff does not take into account that and to accomplish coaxially by three even more bearings, because such difficulty of processing is very big, also it is not easily accomplished, this utility model not only overcomes technology prejudice, it is additionally arranged intermediate bearing, accomplish the coaxial bearing of three or more, and create superior technique effect, make main shaft not easily flexural deformation or damage, run more stable, and the workpiece quality of processing is better.Described active oblique gear and transfer helical gear are 45 degree of helical gears, thus realizing vertical-transmission.Described intermediate bearing is fixedly mounted in the bearing cross hole 10 in set casing body, intermediate bearing is fixed by bearing cross hole 10, diagram is provided with three intermediate bearings 9, ensure that the stability of main shaft, the number of intermediate bearing is determined according to the group number of active oblique gear 6, one intermediate bearing is set between two groups of active oblique gears, two intermediate bearings are then set between three groups of active oblique gears, three intermediate bearings are then set between four groups of active oblique gears.Described first and second row transfer the tip of the axis is equipped with tool holding device 11, and tool holding device is used for clamping machining tool.
Additionally, this utility model is not limited to above-mentioned embodiment, as long as it reaches technique effect of the present utility model with essentially identical means, protection domain of the present utility model all should be belonged to.
