Abstract

The utility model relates to an adjusting device for a grinding wheel with dual grinding particles. The utility model is mainly characterized in that an outside grinding wheel which is integrally formed from outside blocks with rougher grinding particles is arranged on a machine body seat; the end surface of the bottom of each outside block is provided with two wedge blocks; one wedge block is connected with each outside block through a stop ring and a screw nail, and a rubber cushion ring and an inside block are arranged on the plane of the other wedge block; the inside block is provided with an inside grinding wheel which is integrally formed from finer grinding particles; the inside block, the rubber cushion ring, the two wedge blocks and the outside block are connected with the machine body seat through screw bolts. The height difference between the dual grinding particles of the utility model can be adjusted at will. The utility model has the advantages of long service life, high processed surface smoothness and precision, and good grinding dynamic characteristic.

Description

A kind of emery wheel adjusting device that has double abrasive particle

The utility model relates to a kind of emery wheel adjusting device that has double abrasive particle.

The known grinding wheel unit that has double abrasive particle, the emery wheel one that all can not regulate double abrasive particle arbitrarily is the height between outside emery wheel and the inboard emery wheel, come with some shortcomings like this, difference in height outside the first is worked as, between the inboard emery wheel is less or bigger, grinding wheel unit just can not be brought into play due function preferably, when outside, difference in height between the interior emery wheel hour, the surface smoothness and the precision of processing are relatively poor; When outside, when difference in height between the interior emery wheel is big, the cutting force that inboard emery wheel is subjected to is bigger, therefore easily stops up in the processing and wearing and tearing and cause grinding burn, so the life-span of grinding wheel unit is shorter.It two is that outer, inboard emery wheel is by rigidly connected, and the dynamic characteristic that then shows grinding sometimes is relatively poor.

The purpose of this utility model is to overcome the deficiency in the known technology and provides a kind of long service life, processed surface smoothness and precision dynamic characteristic higher and grinding also to have the emery wheel adjusting device of double abrasive particle preferably.

The purpose of this utility model is achieved in that

On the boss inwall of body seat of the present utility model, install 12～14 and all have outer lateral mass on it than coarse grit, 12～14 whole outside emery wheels that form of outer lateral mass, outside each, place two voussoirs that cooperatively interact on the bottom end face of lateral mass respectively, the one voussoir is connected outer lateral mass by screw with baffle ring, on the plane of another voussoir, place rubber washer and interior lateral mass successively, the total quantity of lateral mass equates with total outside number of blocks in described, 12～14 inboard emery wheels of the whole formation of interior lateral mass, in each, all have than fine grit interior lateral mass and rubber washer and two voussoirs on the lateral mass, outer lateral mass all is connected with the body seat by bolt.

The utility model has following accompanying drawing:

Fig. 1 is a front view of the present utility model;

Fig. 2 is the partial sectional view in A-A cross section among Fig. 1.

Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail:

On the boss inwall of body seat 1, be adjacent to 12～14 outer lateral mass 2 are installed, at each outside, all have than coarse grit emery wheel outside the whole formation on the lateral mass.Place voussoir 3 and the voussoir 7 that cooperatively interacts outside each on the bottom end face of lateral mass respectively, wherein voussoir 3 is to be connected to a fixed by the through hole on baffle ring 4 and screw 5 and the outer lateral mass.Place rubber washer 6 and interior lateral mass 8 on the plane of voussoir 7 successively, the final inboard number of blocks of placing is corresponding with above-mentioned outside number of blocks.In each, all have than fine grit the inboard emery wheel of whole formation on the lateral mass.Interior lateral mass and rubber washer and voussoir 3, voussoir 7, outer lateral mass all link together by bolt 9 and body seat.

Operation principle of the present utility model is: before processing or in the processing, if when finding that excessive or the too small or inboard plane of grinding wheel degree of difference in height is relatively poor between outside emery wheel and the inboard emery wheel, at first unclamp bolt 9, with instrument rotary screw 5, drive voussoir 3 move left and right by its screw thread, make the voussoir 7 that cooperates with it move up and down, reach inboard emery wheel and also move up and down, to be adjusted behind certain position, fastening bolt 9 again.

Advantage and the good effect that the utlity model has are: because inboard emery wheel and outside emery wheel The emery wheel of the double abrasive particle that forms can be regulated height between them by voussoir and screw Difference, so its difference in height can according to the requirement of working (machining) efficiency and precision, be regulated arbitrarily. So this It is longer that utility model had both reached service life, and it is also better to reach again processed surface smoothness and precision Purpose. In addition, again because the novel medial and lateral emery wheel of this usefulness adopts is the elasticity connection, Then the dynamic characteristic of the utility model grinding is also better.

Claims

1. emery wheel adjusting device that has double abrasive particle, mainly be by the body seat, outside emery wheel, inboard emery wheel, bolt is formed, it is characterized in that: on the boss inwall of body seat, install 12～14 and all have outer lateral mass on it than coarse grit, 12～14 whole outside emery wheels that form of outer lateral mass, outside each, place two voussoirs that cooperatively interact on the bottom end face of lateral mass respectively, the one voussoir is connected outer lateral mass by screw with baffle ring, on the plane of another voussoir, place rubber washer and interior lateral mass successively, the total quantity of lateral mass equates with total outside number of blocks in described, 12～14 inboard emery wheels of the whole formation of interior lateral mass, in each, all have than fine grit interior lateral mass and rubber washer and two voussoirs on the lateral mass, outer lateral mass all is connected with the body seat by bolt.
