Description
Technical field
This utility model relates to grinding machine field, particularly relates to a kind of grinding machine screw mandrel adjusting apparatus.
Background technology
Column Mobile plane grinding machine is the one of grinding machine.Main with emery wheel spin finishing workpiece so that it can reach wants
The flatness asked, can be divided into circular table two kinds according to workbench shape, and the principal parameter of rectangular table surface grinding machine is work
The principal parameter of station width and length is diameter of table surface.Difference according to axle class can be divided into horizontal axis and vertical shaft grinder point.
Wherein the leading screw of grinding machine is actuated element most-often used on machine tool and precision optical machinery, and its major function is by rotary motion
It is converted into linear movement, or torque axis is changed into axial repeated action power, have high accuracy, reversibility and high efficiency spy simultaneously concurrently
Point.Owing to having the least frictional resistance, ball-screw is widely used in various industrial equipment and precision instrument.Ball-screw
It is made up of screw rod, nut, steel ball, pre-tabletting, reverser, dust excluder.Its function is the motion that is in line by convert rotational motion,
This is extending further and development of Ai Kemu screw rod, and bearing is become rolling from sliding action by the significance of this development exactly
Dynamic action.Often there is pogo stick situation in existing grinding machine screw mandrel, nut or common round nut on grinding machine screw mandrel add round spiral shell
Female washer locking, or time two round nuts lockings, or use accurate locking nut locking.But all do not have directly to adjust
Whole screw rod jitter, screw rod jitter amplitude is relatively big, increases the abrasion of screw mandrel, reduces the service life of screw mandrel.
Based on above reason, a kind of grinding machine screw mandrel adjusting apparatus is needed to be devised, by the contact plane at nut
On process four uniform tapped through holes, put into four flush end holding screws the shortest than nut thickness.Assembler can
To adjust beating of screw mandrel by four flush end holding screws of regulation.The i.e. dextrorotation when measuring the high point of screw mandrel ending pulsation
Flush end holding screw above turning, and the flush end holding screw above rotating counterclockwise when measuring the low spot of screw mandrel ending pulsation,
Screw rod jitter is adjusted with this, simple and practical, i.e. a kind of grinding machine screw mandrel adjusting apparatus.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of grinding machine screw mandrel adjusting apparatus.
This utility model is to be achieved through the following technical solutions:
A kind of grinding machine screw mandrel adjusting apparatus, including screw mandrel, described screw mandrel is arranged on bearing block, described screw mandrel and bearing block
Linked by bearing；Described screw mandrel is positioned by gland；The middle part of described gland is provided with adjusting nut, described adjustment spiral shell
Female is evenly distributed in flush end holding screw；Adjustment packing ring, described gland and axle are installed between described adjusting nut and gland
Junction between bearing is provided with packing ring.
Further, the quantity of described flush end holding screw has four, and described flush end holding screw is uniformly distributed along the circumference and is adjusting
On the end face of whole nut.
Further, four ends of described adjusting nut all offer groove, it is simple to degree of tightness adjusting nut.
Compared with prior art, the beneficial effects of the utility model are: this utility model simple in construction, reasonable in design,
By processing four uniform tapped through holes on the contact plane of nut, put into four flush ends the shortest than nut thickness
Holding screw.Assembler can adjust beating of screw mandrel by four flush end holding screws of regulation.I.e. measuring screw mandrel end
Flush end holding screw above turning clockwise during the high point beated, and rotate counterclockwise when measuring the low spot of screw mandrel ending pulsation
The flush end holding screw of top, adjusts screw rod jitter with this, simple and practical.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing and enforcement
Example, is further elaborated to this utility model.Should be appreciated that specific embodiment described herein is only in order to explain
This utility model, is not used to limit this utility model.
Referring to Fig. 1-2, Fig. 1 is structural representation of the present utility model, and Fig. 2 is side view of the present utility model.
A kind of grinding machine screw mandrel adjusting apparatus, including screw mandrel 1, described screw mandrel 1 is arranged on bearing block 2, described screw mandrel 1 and axle
Bearing 2 is linked by bearing 3；Described screw mandrel 1 is positioned by gland 4；The middle part of described gland 4 is provided with adjusting nut 5,
Described adjusting nut 5 be evenly distributed in flush end holding screw 7；Between described adjusting nut 5 and gland 4, adjustment packing ring is installed
6, the junction between described gland 4 and bearing block 2 is provided with packing ring 8；The quantity of described flush end holding screw 7 has four, institute
State flush end holding screw 7 to be uniformly distributed along the circumference on the end face of adjusting nut 5；Four ends of described adjusting nut 5 all offer
Groove, it is simple to degree of tightness adjusting nut 5.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all at this
Any amendment, equivalent and the improvement etc. made within the spirit of utility model and principle, should be included in this utility model
