Description
Technical field
The utility model is related to it is a kind of can machining high-precision eccentric shaft follow-up grinder structure type.
Background technology
Currently, the finishing to eccentric shaft, the follow-up grinder for being all made of traditional sense both at home and abroad carries out.Its principle is：With
The rotation of each circle of eccentric shaft, grinding wheel carries out primary regular advance and retreat, to complete the processing of its eccentric cylinder.
As stated above, one：Since the center height of the centre of gyration of the center height and workpiece of grinding wheel spindle is certain, and
But work in-process constantly changes at the center of ground eccentric cylinder part, this allows for grinding points cannot be in bias always
On the line at circle center and grinding wheel center, and have to solve the problems, such as rounding by the way of grinding wheel radial direction interpolation, it may
Cause the deviation from circular from of processing off-centre operation；Secondly；Due to the presence for the reversal point of grinding wheel diametrically reciprocated, the sound of commutation
Speed is answered to also contribute to the quality of workpiece off-centre operation.
Therefore, it is necessary to a kind of new follow-up grinder synchronous rotating devices to solve the above problems.
Utility model content
Purpose of utility model：In order to overcome problems of the prior art, a kind of follow-up grinder synchronous revolving dress is provided
It sets.
In order to solve the above technical problems, technical side used by a kind of follow-up grinder synchronous rotating device of the utility model
Case is：
A kind of follow-up grinder synchronous rotating device, for processing eccentric work piece, including processing grinding wheel, the processing grinding wheel is
Eccentric grinding wheel.
Further, the processing grinding wheel includes grinding wheel, eccentric overcoat, eccentric inner sleeve and grinding wheel spindle, and the bias is outer
Be provided with the first eccentric inner hole on the inside of set, be set in first eccentric inner hole in the bias and with described first partially
Intracardiac hole is connected；It is provided with the second eccentric inner hole on the inside of the bias inner sleeve, the grinding wheel spindle is arranged described second
It is connected in eccentric inner hole and with second eccentric inner hole, the grinding wheel is fixedly connected with the eccentric overcoat.
Further, the processing grinding wheel includes grinding wheel, eccentric shaft and grinding wheel spindle, is provided on the inside of the eccentric shaft
Through-hole, the grinding wheel spindle are arranged in the through-hole.Simple in structure, it is convenient to realize, utilizes the position tune of through-hole relative eccentric axis
Save the eccentricity of eccentric shaft.
Further, the through-hole is strip through-hole.By adjusting position of the grinding wheel spindle in strip through-hole, adjust inclined
The eccentricity of mandrel.
Further, the quantity of the through-hole is multiple and different from the axle center of eccentric shaft distance.Conveniently pass through
Grinding wheel spindle is arranged in different through-holes, the eccentricity of eccentric shaft is adjusted.
Inventive principle：
In grinding, the relative rotation of eccentric inner sleeve and eccentric overcoat is adjusted, makes grinding wheel spindle relative in housing outside cylinder
Eccentricity of mandrel line etc. is used for the eccentricity required by workpiece to be machined, and locks.
The rotating speed and workpiece rotational frequency constant speed of eccentric overcoat are set, and keeps the two eccentric direction consistent, while synchronous rotary, this
When, for grinding wheel spindle while rotation, it is circle that axis is formed by movement locus with housing rotation, inclined with being processed on workpiece
Heart circle center movement locus is completely the same, in this way, realizing the grinding of workpiece off-centre operation.
Advantageous effect：The follow-up grinder synchronous rotating device of the utility model, simple in structure, it is convenient to realize, has processing
Mode is simple, and precision is high, the low feature of error.
Description of the drawings
Fig. 1 is the principle schematic of the follow-up grinder synchronous rotating device of the utility model.
Specific implementation mode
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, art technology
Personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
Refering to Figure 1, the follow-up grinder synchronous rotating device of the utility model is wrapped for processing eccentric work piece (1)
Processing grinding wheel is included, processing grinding wheel is eccentric grinding wheel.
Embodiment 1：
Processing grinding wheel includes that grinding wheel 2, eccentric overcoat 3, eccentric inner sleeve 4 and grinding wheel spindle 5, the inside of eccentric overcoat 3 are provided with
First eccentric inner hole 6, eccentric inner sleeve 4 are arranged in the first eccentric inner hole 6 and are connected with the first eccentric inner hole 6；In bias
The inside of set 4 is provided with the second eccentric inner hole 7, and grinding wheel spindle 5 is arranged in the second eccentric inner hole 7 and matches with the second eccentric inner hole 7
Connection is closed, grinding wheel is fixedly connected with eccentric overcoat 3.
Inventive principle：
In grinding, the relative rotation of eccentric inner sleeve and eccentric overcoat is adjusted, makes grinding wheel spindle relative in housing outside cylinder
Eccentricity of mandrel line etc. is used for the eccentricity required by workpiece to be machined, and locks.
The rotating speed and workpiece rotational frequency constant speed of eccentric overcoat are set, and keeps the two eccentric direction consistent, while synchronous rotary, this
When, for grinding wheel spindle while rotation, it is circle that axis is formed by movement locus with housing rotation, inclined with being processed on workpiece
Heart circle center movement locus is completely the same, in this way, realizing the grinding of workpiece off-centre operation.
The special construction of this lathe is a shell type main axle structure, and eccentric inner sleeve and eccentric overcoat are eccentric bushing, eccentricity
It is equal.Grinding wheel spindle is eccentrically mounted in eccentric inner sleeve, and first that the outer circle of eccentric inner sleeve is coaxially installed on eccentric overcoat is eccentric
In endoporus.In this way, when rotating eccentric inner sleeve when eccentric overcoat is motionless, the central axis of grinding wheel spindle is relative to the outer of eccentric overcoat
Cylindrical center's axial line distance just changes；When eccentric inner sleeve and eccentric overcoat bias are conjugated, the central axis of grinding wheel spindle with
The outside cylinder central axis of eccentric overcoat overlaps；When non-conjugated, the central axis of grinding wheel spindle and the outside cylinder center of eccentric overcoat
Axis generates displacement, that is, generates eccentricity, which can be adjusted.
The outside cylinder center of eccentric overcoat is designed as work rotation center, work in-process rotation.
Embodiment 2：
Processing grinding wheel includes grinding wheel 2, eccentric shaft and grinding wheel spindle, and through-hole, the grinding wheel are provided on the inside of the eccentric shaft
Axis is arranged in the through-hole.Preferably, eccentric shaft is cylinder.Through-hole is strip through-hole and the axle center by eccentric shaft.Pass through
Position of the grinding wheel spindle relative to eccentric shaft is adjusted, the eccentricity of processing grinding wheel is adjusted.
The quantity of another realization method, through-hole is that multiple and axle center distances from eccentric shaft is different.It is convenient by by grinding wheel
Axis is arranged in different through-holes, adjusts the eccentricity of eccentric shaft.
The follow-up grinder synchronous rotating device of the utility model, simple in structure, it is convenient to realize, has processing method simple,
Precision is high, the low feature of error.
