The utility model discloses a set up the recess and can get rid of the lapping rejects that grinds the production on the rinding body, make to keep when grinding whole plane being disturbed by free from admixture (or lapping rejects) between abrasive surface and frosting, more do benefit to the smooth finish and the plane degree of improvement abrasive surface.
Description
Technical field
This utility model relates to metal polishing machine mechanical field, particularly relates to a kind of grinder head.
Background technology
Existing this grinding wheel head structure is in the real work of mirror grinding machine, need on bistrique, be enclosed with sponge or wool felt, the sheet material being sent into is ground, during sheet material is ground by bistrique, if the pressure of bistrique is excessive, sponge or wool felt sintering can be caused, thus affect the quality of grinding, simultaneously during grinding, it is connected owing to bistrique and electric machine main shaft are fixing, bistrique is often unbalance stress during grinding, and then can cause sheet material that polishing scratch occurs, have a strong impact on the quality of product, it is threadably secured connection additionally, due to existing this grinding head motor main shaft and bistrique, the operation of replacing bistrique trouble extremely, require a great deal of time.
Further, the abrasive body of existing bistrique and the face of absorption surface are plane, and in process of lapping, easily between abrasive body and surface of the work, accumulated impurity or chip etc. cause grinding removal amount uneven, affect the Grinding Quality of surface of the work.
Summary of the invention
For defect present in prior art, the technical problems to be solved in the utility model is to provide a kind of grinder head, with solve in process of lapping easily between abrasive body and surface of the work accumulated impurity or chip etc. cause grinding removal amount uneven, the problem affecting the Grinding Quality of surface of the work.
In order to realize above-mentioned purpose, the technical scheme that this utility model offer is following:
Grinder head, including electric machine main shaft, bistrique and bistrique set, bistrique set upper side is fixing with electric machine main shaft to be connected, the lower end socket of bistrique set is installed in described bistrique, bistrique upper end is installed with baffle plate, and bistrique set upper side passes from described baffle plate, is provided with adjusting means between bistrique set and bistrique, bistrique lower end is provided with abrasive body, and abrasive body radially offers groove.
Further, described adjusting means is compression spring, and spring structure is simple, low cost.
Further, described baffle plate is secured by bolts in bistrique, when bistrique set with bistrique between compression spring elasticity the best time, can be by baffle plate dismounting and change compression spring, to guarantee bistrique uniform force.
Further, described electric machine main shaft is connected by screw is fixing with bistrique set, when bistrique needs mounting or dismounting, needs the most replaceable bistrique of knockout screw, complicated procedures of forming when changing threaded, saves the time.
Further, described channel section is square or semicircle, and the quantity of groove is six, and described groove is evenly distributed on abrasive body.
This utility model compared with prior art, has a following technical advantage:
1) this utility model is by increase adjusting means between overlapping at bistrique and bistrique, solves the technical problem causing Grinding Quality low in prior art because bistrique is stressed excessive, unbalance stress, it is ensured that the quality of product.
2) connected mode of screw taked by bistrique and bistrique set by this utility model, instead of the connected mode of conventional threads, decreases the replacing construction of bistrique, improves work efficiency.
3) this utility model can get rid of, by arranging groove on abrasive body, the lapping rejects that grinding produces, and makes to keep during the whole plane of grinding being ground free from admixture between face and frosting (or lapping rejects) interference, is more conducive to fineness and the flatness of raising abradant surface.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model grinder head；
Fig. 2 is the bottom surface structure schematic diagram of grinder head shown in Fig. 1.
Detailed description of the invention
Accompanying drawing being merely cited for property explanation, it is impossible to be interpreted as the restriction to this patent.
To those skilled in the art, in accompanying drawing, some known features and explanation thereof may will be understood by omission.
Below in conjunction with the accompanying drawings and embodiment, this utility model technical scheme in real is clearly and completely described.
It is illustrated in figure 1 the grinder bistrique of the new embodiment of this practicality, including electric machine main shaft 1, described electric machine main shaft 1 is connected by screw is fixing with the upper end of bistrique set 4, the lower end socket of bistrique set 4 is installed in bistrique 2, and bistrique set 4 is arranged above baffle plate 6, and baffle plate 6 is fixed on described bistrique 2 by bolt 7, the upper end of bistrique set 4 passes from baffle plate 6, bistrique set 4 and bistrique 2 between adjusting means 8 is installed, as of the present utility model preferably, adjusting means 8 is compression spring.
As shown in Figure 1, when not using grinder bistrique of the present utility model, owing to bistrique 2 and electric machine main shaft 1 one are connected by screw thread 3, when bistrique 2 is stressed excessive or unbalance stress, the quality of grinding can be severely impacted, and the mounting or dismounting operation of bistrique 2 is complex, after using grinder bistrique of the present utility model, compression spring is had by increasing between bistrique set 4 and bistrique 2, can effectively adjust the stress of bistrique 2, ensure bistrique 2 uniform force, and then improve the quality of grinding, decrease the replacing construction of bistrique simultaneously, improve work efficiency.
As in figure 2 it is shown, the lower end of bistrique 2 is abrasive body, on the lower surface that abrasive body contacts with surface of the work along the radial direction of bistrique 2 through be provided with groove 9, the cross sectional shape of groove 9 is square or semicircle, can be beneficial to the machine-shaping of groove 9；Due to the existence of groove 9, can get rid of during bistrique grinding and grind the lapping rejects produced, make to keep during the whole plane of grinding being ground free from admixture between face and frosting (or lapping rejects) interference, be more conducive to improve fineness and the flatness of abradant surface.As preferably, the quantity of groove 9 is six, and is evenly arranged along the circumferencial direction of bistrique 2, so can be more beneficial for the discharge of grinding impurity, improves fineness and the flatness of abradant surface further.
Above-described embodiment of the present utility model is only for clearly demonstrating this utility model example, and is not the restriction to embodiment of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in this utility model scope of the claims.
