Description
Technical field
The utility model is related to a kind of devices that grinding oscillation mark is mitigated or eliminated, and belong to mechanical processing ancillary equipment technology neck
Domain.
Background technology
Workpiece can be trembled in grinding process due to mechanical high-speed movement, and wheel face will appear uneven wear,
Make part and wheel face that can generate ripple mark, so as to limit further improving for grinding accuracy, surface quality and productivity.
When being ground slender rod piece on grinding machine, due to the workpiece, rigidity itself is relatively low, during rod piece is ground easily
Vibration is generated, workpiece surface is caused to generate oscillation mark, influences the quality of workpiece.
It has been investigated that machine vibration is the main reason for workpiece surface is made to generate oscillation mark.There are many factor of machine vibration,
Prevent machine vibration from needing to investigate determining vibration source, investigation motor, bistrique, belt pulley, grinding wheel, hydraulic system etc..It however should
The investigation period is long, and can not effectively avoid or weaken the generation of oscillation mark in practical operation.In addition, traditional raising grinding
The method of precision further includes：(1) consider from workpiece axial rigidity the weakest point, to choose workpiece rotational frequency Vw, length feed speed VfInto
Row constant speed is ground, while uses grinding depth as small as possible.Therefore, parameter Vw、VfAt those larger points of rigidity
Value would be impossible to become optimum point, necessarily bring grinding expense and waste of time in this way；(2) workpiece is improved using centre frame
The method of rigidity, processing efficiency is all very low, and adjustment is complicated, and more demanding to worker's technology, improves the effect of machining accuracy
It is very limited；(3) taking error compensation measure, there are two types of the technological compensa tion strategy of strategy, repair adjustment etc and apolegamys etc
Into group policy, the stock removal of each processing stand is calculated by formula, work in-process forces the practical grinding amount of workpiece to reach calculating
Value, to reduce the influence of flexible deformation.But calculating the stock removal at a certain moment and flexible deformation in Grinding Process is
Highly difficult.
Oscillation mark and the not flexible grinding of the device realization oscillation mark of disfiguring workpiece are ground therefore, it is necessary to a kind of, to improve workpiece
Machining accuracy, and then improve processing quality.
Utility model content
First purpose of the utility model is to provide a kind of device that grinding oscillation mark is mitigated or eliminated, and the disk is vertical
It is set on the base, and can be moved along the shaft rotation of disk；Two are disposed radially on the circumference of disk at a distance of 100~130 ° of spiral shell
Hole；One end of the round steel is threaded, and the end of thread of two round steel is separately fixed in the screw hole of disk, wherein a round steel
At least one weight that can be moved axially along round steel of upper setting.
In a kind of embodiment of the utility model, the disk fixes along axis and pedestal by shoulder screw
In a kind of embodiment of the utility model, the convex shoulder length of the shoulder screw is more than the axial thick of disk
Degree, makes disk that can be moved along shaft rotation.
In a kind of embodiment of the utility model, at a distance of 120 ° between screw hole.
In a kind of embodiment of the utility model, the weight is fixed on by thumbscrew on round steel.
In a kind of embodiment of the utility model, the pedestal is cube.
The equipment that the utility model also provides the device that grinding oscillation mark is mitigated or eliminated containing described in.
Advantageous effect：The utility model provides a kind of dress that grinding oscillation mark is mitigated or eliminated suitable for rod piece processing
Put, the vibration that occurs when which can weaken grinding workpiece by way of damping vibration, will grinding vibration reduce by 60~
70%, the grinding oscillation mark of workpiece is substantially reduced, improves the processing quality and efficiency of workpiece, it is cost-effective.

Specific embodiment
As shown in Figs. 1-2, a kind of device that grinding oscillation mark is mitigated or eliminated of the utility model include weight 1, round steel 3,
Disk 6 and pedestal 5；The pedestal 5 is cube；The disk 6 is vertically arranged, and disk 6 passes through horizontally disposed convex shoulder along axis
Screw 4 is fixed with pedestal 5, and the convex shoulder length of shoulder screw 4 is more than the axial width of disk 6, makes disk 6 that can be moved along shaft rotation；Circle
The screw hole that two angles are in 100~130 ° is disposed radially on the circumference of disk 6；One end of the round steel 3 is threaded, the other end
End face is smooth；The end being threaded of two round steel 3 is separately fixed in the screw hole of disk 6.It is set on a wherein round steel 3
It is at least one circle to be fixed on by thumbscrew 2 along the mobile weight 1 of round steel axial (i.e. the length direction of round steel), weight 1
On steel 3.
The working method of the utility model is：Pedestal 5 is fixed on work top, shoulder screw is passed through into disk 6
Disk 6 is simultaneously fixed on the side wall of pedestal 5 by axis vertically.Since convex shoulder length is more than the thickness of disk axial direction, disk can be along convex
Shoulder screw rotates.Weight 1 on long round steel 3 is adjusted to suitable position, weight 1 is fixed by thumbscrew 2, is turned by rotation
The smooth end of the round steel for being not provided with weight is resisted workpiece 7 by disk.When workpiece 7 is by grinding, the vibration of grinding passes through
Round steel 3 is transferred at weight 1, weakens the Oscillation Amplitude at processed workpiece by way of damping vibration.The utility model
Device grinding vibration can be reduced by 60~70%, substantially reduce the grinding oscillation mark of workpiece.
