Description
Technical field
The present invention relates to a kind of feed compensation mechanism of double-ended grinding machine.
Background technology
Double-ended grinding machine is used for the cross grinding of the inside and outside set of small size bearing, and its crudy can not have been fully met at present
High-precision product quality requirement,
Problems be present：(1) the feed compensation mechanism of bistrique is to drive a set of mechanical reduction gear again through cunning by cylinder
Nut in dynamic screw pair is spacing to realize compensation, and mechanism is complicated, and transmission link is more, influences transmitting accuracy；(2) bistrique
The amount of feeding and correcting compensation amount be by operator by rule of thumb depending on, the machining accuracy of product is had a direct impact, particularly
Processing to high-precision bearing, it is difficult to reliably ensure its technical requirements；(3) traditional Control is used, it is reliable
Property is poor, and maintenance load is big.
The content of the invention
The technical problem to be solved in the present invention is：Based on above mentioned problem, there is provided a kind of feed compensation machine of double-ended grinding machine
Structure.
The technical solution adopted for the present invention to solve the technical problems is：A kind of feed compensation mechanism of double-ended grinding machine,
Including emery wheel cylinder, emery wheel and the limited block being connected between emery wheel cylinder and emery wheel, limited block is connected with ball-screw, rolling
Ballscrew is connected with bearing, and bearing is connected with harmonic speed reducer, and harmonic speed reducer is connected with stepper motor.
The beneficial effects of the invention are as follows：It is to realize motion using the controllable elastic deformation of flexible member with harmonic speed reducer
Transmission or power transmission, compared with former reducing gear, there is the advantages that gearratio is big, and precision height is compact-sized, easy to use；
Clearance adjustable type ball screw assembly, original sliding friction is changed into rolling friction, friction loss is small, fixed through appropriate pre- next
Position precision is high, it is ensured that uses transmission accuracy.
Brief description of the drawings
The present invention is further described below in conjunction with the accompanying drawings.
Fig. 1 is the structural representation of the present invention.
Wherein：1. emery wheel cylinder, 2. emery wheels, 3. limited blocks, 4. ball-screws, 5. bearings, 6. harmonic speed reducers, 7. steppings

Embodiment
Presently in connection with accompanying drawing, the present invention is further illustrated.These accompanying drawings are simplified schematic diagram only with signal side
Formula illustrates the basic structure of the present invention, therefore it only shows the composition relevant with the present invention.
A kind of feed compensation mechanism of double-ended grinding machine as shown in Figure 1, including emery wheel cylinder 1, emery wheel 2 and be connected to
Limited block 3 between emery wheel cylinder 1 and emery wheel 2, limited block 3 are connected with ball-screw 4, and ball-screw 4 is connected with bearing 5, axle
Hold 5 and be connected with harmonic speed reducer 6, harmonic speed reducer 6 is connected with stepper motor 7.
NC machine tool feed system is to the position of feed motion and two aspects of speed of motion while realizes automatic control
System, compared with machine tool, in addition to higher positioning accuracy is required, should also have good dynamic response characteristic.This lathe is left and right
Symmetrical two bistriques are when making feed compensation motion, it is desirable to have higher transmitting accuracy, therefore, being to utilize with harmonic speed reducer
The controllable elastic deformation of flexible member realizes the transmission or power transmission of motion, big with gearratio compared with former reducing gear,
Precision is high, compact-sized, it is easy to use the advantages that.
Originally relative motion is to slide between the leading screw and nut of lathe, and abrasion is more serious, influences transmitting accuracy, here
Use clearance adjustable type ball screw assembly, instead, original sliding friction is changed into rolling friction, friction loss is small, through appropriate pretension
Afterwards, positioning precision is high, it is ensured that uses transmission accuracy.
Using micro-processor controlled stepper motor, stepper motor is that a kind of electromechanics that electric pulse is converted into mechanical angular displacement is held
Units, the accuracy of control feed compensation amount is improved using its this feature.
The bistrique is to use penetration type feeding continuous grinding technology mode, and the dimensional accuracy and form accuracy of workpiece depend on mill
The operating position of head and the processing amount of feeding, are originally by any time sampling observation of the operator to workpiece after processing, by mechanical handwheel control
The amount of feeding and correcting compensation amount of bistrique processed, workpiece processing quality is to a certain extent by the sense of responsibility and technical merit of operator
Influence.Present workpiece discharge outlet increases the automatic measuring instrument of a measurement workpiece size, will measure the workpiece chi after processing
Very little information carries out analog/digital conversion, original to replace so as to realize the closed-loop control that motion is compensated to left and right grinding head grinding wheel
Control feed compensation motion manually.
It is complete by above-mentioned description, relevant staff using the above-mentioned desirable embodiment according to the present invention as enlightenment
Various changes and amendments can be carried out without departing from the scope of the technological thought of the present invention' entirely.The technology of this invention
Property scope is not limited to the content on specification, it is necessary to determines its technical scope according to right.
