Abstract
The present invention provides the control of grinding force mechanisms of the electro spindle of grinding machine, can ensure that grinding force is constant, it is ensured that workpiece grinding quality.It includes force snesor, and the sense base of force snesor is installed on electro spindle seat, its reference seat is installed on feed slide, and the servo motor of the output end and control grinding wheel of force snesor electricly connects；Electro spindle seat both ends are supported on feed slide by elastic component.
Description
Technical field
The present invention relates to technical fields of mechanical processing, and in particular to the control of grinding force mechanism of the electro spindle of grinding machine.
Background technique
It is installed on the feed slide of feed mechanism currently, the electro spindle of grinding machine generally passes through electro spindle seat, on electro spindle
Servo motor equipped with driving grinding wheel rotation.In grinding, generally feeding machine will be given apart from instruction feedback by displacement sensor
Structure controls grinding by driving grinding wheel to advance.But as workpiece is ground the variation of degree, grinding force suffered by workpiece, i.e. grinding wheel mentions
The grinding force of confession cannot keep constant, influence workpiece grinding quality.
Summary of the invention
In view of the above-mentioned problems, grinding force can be maintained the present invention provides the control of grinding force mechanism of the electro spindle of grinding machine
It is constant, it is ensured that workpiece grinding quality.
Its technical solution is such comprising force snesor, the sense base of the force snesor are installed on electro spindle seat
Upper, its reference seat is installed on feed slide, and the servo motor of the output end and control grinding wheel of the force snesor electricly connects；
Electro spindle seat both ends are supported on feed slide by elastic component.
Further, the elastic component is steel spring plate.
Further, one end of the steel spring plate is fixedly connected by pressing plate, bolt with the electro spindle seat, another
One end is fixedly connected by bolt, nut with the attachment base on feed slide.
Using control mechanism of the invention, since electro spindle seat both ends are supported on feed slide by elastic component, with
Workpiece is ground the variation of degree, and elastic deformation occurs for spring part, can generate relative displacement between electro spindle seat and feed slide,
Grinding force suffered by workpiece also changes therewith simultaneously, and the variation of this power feeds back to servo motor, Jin Ertong by force snesor
The adjusting of the revolving speed of servo motor is crossed, control grinding wheel provides constant grinding force, so that it is guaranteed that workpiece grinding quality.
Detailed description of the invention
Fig. 1 is the structural diagram of the present invention；
Fig. 2 is partially enlarged structural schematic diagram at A of the present invention.
Specific embodiment
As shown in Figure 1 and Figure 2 comprising force snesor, the sense base 42 of the force snesor is installed on electro spindle seat 2,
Its reference seat 41 is installed on feed slide 3, and the servo motor of the output end and control grinding wheel of the force snesor electricly connects,
Supporting element 43 is the component part of force snesor in Fig. 1, is used to support, connects sense base 42 and reference seat 41；The electro spindle
2 both ends of seat are supported on feed slide 3 by steel spring plate 5.Specifically, as shown in Fig. 2, one end of the steel spring plate 5 is logical
Cross pressing plate 7, bolt 6 is fixedly connected with the electro spindle seat 2, the other end passes through the company on bolt 6, nut 9 and feed slide 3
Joint chair 8 is fixedly connected.
The quantity of steel spring plate 5 can be set according to actual conditions, and also can be replaced other with elasticity and have certain branch
The elastic component of support ability.
