Abstract
The utility model provides a kind of main shaft left-hand thread seat effectively reducing maintenance, which is characterized in that including pedestal, the pedestal is cylindrical, and the pedestal is internally provided with axle sleeve platform, and set axis hole is equipped in the middle part of the axle sleeve platform, the pedestal wall is axially arranged with several screw holes, and the pedestal wall is equipped with oil extraction steam vent.Oil and steam can be discharged in the design in time, avoid lubricating oil and steam from mixing, dilution, lead to bearing damage.
Description
Technical field
The utility model is related to a kind of main shaft left-hand thread seats for lathe, and in particular to a kind of master effectively reducing maintenance
Axis left-hand thread seat.
Background technology
Mechanical main shaft refers to the axis that workpiece or cutter rotation are driven on lathe.Usually by main shaft, bearing and driving member（Tooth
Wheel or belt wheel）Deng composition spindle unit.It is mainly used to support driving parts such as gear, belt wheel in the machine, transmit movement and turns round
Square, such as machine tool chief axis；Some is used for clamping workpiece, such as mandrel.
Find that main shaft upper end oil cylinder has oil and steam leakage during spindle mounted and use, without suitable labyrinth
Oil and steam is discharged in structure and oil discharge outlet in time, causes oil and steam that can leak into inside main shaft, dilutes bearing grease, leads to bearing
Damage.Therefore a kind of main shaft protection structure that can effectively reduce maintenance is needed.
Utility model content
Above-mentioned to solve the problems, such as, the purpose of this utility model is to provide a kind of main shafts effectively reducing maintenance
Left-hand thread seat, it is simple in structure, oil and steam can effectively and be timely excluded, has avoided entering inside main shaft with steam, has led to axis
Damage is held, there is wide applicability.
In order to achieve the above objectives, the technical solution of the utility model is：
A kind of main shaft left-hand thread seat effectively reducing maintenance, which is characterized in that including pedestal, the pedestal is cylindrical,
The pedestal is internally provided with axle sleeve platform, and set axis hole is equipped in the middle part of the axle sleeve platform, and the pedestal wall is axially arranged with several screw holes, institute
It states pedestal wall and is equipped with oil extraction steam vent.Oil and steam can be discharged in the design in time, avoid lubricating oil and steam from mixing, dilution, lead
Cause bearing damage.
As being further improved for said program, the pedestal is arranged with two oil extraction steam vents.The design can make row
Oil draining is more quickly timely.
As being further improved for said program, the oil extraction steam vent is clear opening.Straight-through hole machined is simple, and oil extraction vapour
It is efficient.
As being further improved for said program, the inner opening of the oil extraction steam vent is set to axle sleeve platform close to main shaft one
The inner opening of side, the oil extraction steam vent is set to axle sleeve platform and pedestal wall junction.Main axis, oil and steam easily got rid of to
Axle sleeve platform and pedestal wall junction, the design of inner opening can effectively prevent oil extraction vapour process dead angle occur here.
As being further improved for said program, the inner wall of the pedestal is to being equipped with slope at the inner opening of oil extraction steam vent
Degree.The design can make oil gas due to centrifugal force internally harness motion, effectively improve the efficiency of oil extraction vapour.
Compared with prior art, the beneficial effects of the utility model are：
Its is simple in structure, can effectively and timely exclude oil and steam, avoid entering inside main shaft with steam, led to axis
Damage is held, there is wide applicability.
Description of the drawings
Fig. 1 is illustrated by a kind of main shaft left-hand thread holder structure effectively reducing maintenance that the utility model embodiment provides
Figure.
Wherein：

Specific implementation mode
Below with reference to the specific effect of design, concrete structure and generation that embodiment and attached drawing create the utility model
Fruit carries out clear, complete description, adequately to understand purpose, feature and the effect of the utility model creation.The utility model
Every technical characteristic of creation, can be with combination of interactions under the premise of not conflicting conflict.
Referring to Fig. 1, a kind of main shaft left-hand thread seat effectively reducing maintenance, which is characterized in that including pedestal, the pedestal is in
Cylindrical shape, the pedestal are internally provided with axle sleeve platform 1, and 1 middle part of the axle sleeve platform is equipped with set axis hole 2, and the pedestal wall is axially arranged with
Several screw holes 3, the pedestal wall are equipped with oil extraction steam vent 4.
As being further improved for said program, the pedestal is arranged with two oil extraction steam vents 4.
As being further improved for said program, the oil extraction steam vent 4 is clear opening.
As being further improved for said program, the inner opening of the oil extraction steam vent 4 is set to axle sleeve platform 1 close to main shaft
The inner opening of side, the oil extraction steam vent 4 is set to axle sleeve platform 1 and pedestal wall junction.
As being further improved for said program, the inner wall of the pedestal is to being equipped with slope at the inner opening of oil extraction steam vent 4
Degree.
It should be noted that above example is merely intended for describing the technical solutions of the present application, but not for limiting the present application.Although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those of ordinary skill in the art that, it can be to reality
It is modified or replaced equivalently with novel technical solution, it, should all without departing from the range of technical solutions of the utility model
Cover in the right of the utility model.
