Abstract
The utility model discloses a grinding wheel balancing device of a surface grinding machine, which comprises a grinding wheel sleeve used for fixing a grinding wheel and sleeved on a spindle. A ring-shaped groove is arranged on the back surface of the grinding wheel sleeve, three balancing components are disposed in the groove, each balancing component consists of a balancing block, a steel ball and a set screw, the balancing blocks are embedded in the groove, the sections of the balancing blocks along the axial direction of the spindle are fan-shaped, each balancing block is provided with an axial through hole and a radial through hole, and central axes of the axial through holes and those of the radial through holes are crossed, each steel ball is located in each balancing block, and each set screw is driven into each balancing block from each axial through hole. The grinding wheel balancing device is simpler in both structure and operation, and realizes balance of the grinding wheel by means of adjusting the positions of the balancing blocks in the ring-shaped groove.
Description
Technical field
The utility model relates to the machining equipment field, is meant a kind of wheel balancing device of surface grinding machine especially.
Background technology
Surface grinding machine is a kind of of grinding machine, it mainly the abrasion wheel grinding workpiece by at a high speed rotation so that it can meet the requirements of flatness.As the emery wheel of grinding important tool, because the non-uniform Distribution of quality and eccentric the installation all can cause vibration, thereby the grinding of workpiece is caused bigger negative effect, seriously restricting grinding quality and precision.
Usually the method for adjusting wheel balance is, put at emery wheel and to wear a single mandrel and be placed on the balancing stand that constitutes by two levels and parallel smooth iron staff, allow it freely roll and adjust the balancing weight of emery wheel cover, with the balancing weight of emery wheel cover towards the eminence adjustment, when emery wheel no longer freely rolls on balancing stand, just think to reach poised state.This method is called roller type wheel balance method, and this method exists balance quality poor, defective such as uses and the adjustment time is long not too convenient.
Summary of the invention
The utility model provides a kind of wheel balancing device of surface grinding machine, and its structure is comparatively simple, and degree of regulation is higher, and its purpose is to overcome the defective of the balance quality difference that has the bascule existence now.
The technical solution of the utility model is as follows:
The wheel balancing device of surface grinding machine, comprise and be used for fixing emery wheel and be sheathed on emery wheel cover on the main shaft, the back side of described emery wheel cover is provided with the groove of annular, be provided with three balanced components in the described groove, described balanced component is formed by balance weight, steel ball and holding screw, described balance weight is embedded in the groove, and it is fan-shaped along the axial cross section of main shaft, described balance weight has an axially extending bore and a radial direction through hole, and intersect the axis of described axially extending bore and radial direction through hole, and described steel ball is positioned at balance weight; Described holding screw is shot balance weight from axially extending bore.
As improvement of the present utility model, described balanced component is uniformly distributed in the groove of annular.
As further improvement of the utility model, described holding screw is fluting awl end holding screw.
Compared with prior art to description of the present utility model as can be known by above-mentioned, advantage of the present utility model is: structure of the present utility model and operation are all comparatively simple, and it realizes the balance of emery wheel by the position of adjustment piece in circular groove.When holding screw screwed, steel ball just can be pushed up to radial direction through hole, thus with the balance weight tensioner between the two side of groove, and then can prevent that the emery wheel cover that balanced component is rotated at a high speed from throwing away; When holding screw was unscrewed, the degree that holds out against between balance weight and recess sidewall just can reduce, and at this moment balance weight just can move in groove, thereby realized the balance of emery wheel.
Description of drawings
Fig. 1 is the structural representation of emery wheel, main shaft and motor.
Fig. 2 is the structural representation of emery wheel, emery wheel cover and balanced component.
Fig. 3 is the structural representation of emery wheel cover, groove and balanced component.
The specific embodiment
The specific embodiment of the present utility model is described with reference to the accompanying drawings.
Referring to figs. 1 through Fig. 3, surface grinding machine 1 main emery wheel 2 grinding work-pieces that rotate by high speed for the grinding that makes 2 pairs of workpiece of emery wheel reaches certain precision, often need install wheel balancing device 3 additional so that it can meet the requirements of flatness on surface grinding machine 1.As can be seen from Figure, emery wheel cover 4 is sheathed on the main shaft 5, and emery wheel 2 is fixed on the emery wheel cover 4, connects by flange-face coupling 52 between main shaft 5 and the motor shaft 51.
Simultaneously referring to figs. 1 through Fig. 3, the back side of emery wheel cover 4 offers the groove 41 of annular, be evenly distributed with three balanced components 6 in this groove 41, and balanced component 6 is generally fluting awl end holding screw by balance weight 61, steel ball 62 and holding screw 63() form.As can be seen from Figure, balance weight 61 is embedded in the groove 41, and it is fan-shaped along main shaft 5 axial cross sections, described balance weight 61 has an axially extending bore 611 and a radial direction through hole 612, and intersect the axis of axially extending bore 611 and radial direction through hole 612, steel ball 62 is positioned at balance weight 61, and holding screw 63 is shot balance weight 61 from axially extending bore 611.When holding screw 53 screwed, steel ball 62 just can be pushed up to radial direction through hole 612, thus with balance weight 61 tensioners between the two side of groove 41, and then can prevent that the emery wheel cover 4 that balanced component 6 rotated at a high speed from throwing away; When holding screw 63 was unscrewed, the degree that holds out against between balance weight 61 and groove 4 sidewalls just can reduce, and at this moment balance weight 61 just can move in groove 4, thereby realized the balance of emery wheel 2.
Above-mentioned only is the specific embodiment of the present utility model, but design concept of the present utility model is not limited thereto, and allly utilizes this design that the utility model is carried out the change of unsubstantiality, all should belong to the behavior of invading the utility model protection domain.
