The inner cooling grinding polishing device is simple in structure, ingenious in design, low in production cost, long in service life, and stable and reliable in performance.
Description
Technical field
The utility model relates to a kind of polishing grinding equipment, relates in particular to interior cooling grinding and polishing device.
Background technology
In the crisp fritter part processes such as grinding and polishing wafer, the local contact area of grinding and polishing dish and workpiece tends to occur high temperature, sometimes even can reach several Baidu.Not only can the burn surface of part of local high temperature, form affected layer, and can cause the local deformation of part, and then affect its surface figure accuracy.
Existing polisher lapper cooling fluid is by coolant pump sucking-off from tank for coolant, deliver to lathe front cooling fluid control handle through plastic tube, be divided into two-way, one route plastic tube enters the balance staff centre bore by the lathe bed inner chamber and wears axle and go out, be connected on the pipe joint of cylinder pressure head,, by the ejection of pressure head bulb endoporus, be upper interior spray; Another route plastic tube passes upper and lower lathe bed, and main shaft lower end pipe joint is sprayed for lower endoporus simultaneously by a plurality of apertures on inner hole of spindle and mill.On the free abrasive polisher lapper, in this up and down, the type of cooling of spray can't be applied.Therefore, the free abrasive polisher lapper that on market, ratio of precision is higher generally all requires to use in being furnished with the environment of air-conditioning system, but air-conditioning system can only guarantee extraneous temperature constant, and is helpless to the localized hyperthermia district on abrasive disk and workpiece contact-making surface.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of simple in structure, ingenious, long service life of design, and can improve the interior cooling grinding and polishing device of part processed finished products rate and production efficiency.
The technical scheme that its technical problem that solves the utility model adopts is:
Interior cooling grinding and polishing device, comprise the bearing block that is installed with bearing, described bearing is provided with main shaft, main shaft is connected with axle center, be fixed with the grinding collet in the upper end of described main shaft, grind on collet four the stainless steel thimbles that are used for increasing abrasive disk spin friction power that distributing, on described grinding collet, grinding head also is installed, the centre of described grinding head is provided with intake chute, offer inlet channel in described axle center, described intake chute and inlet channel and be located at the inlet opening mutual conduction of transfusion ring side.
It is the groove of 1 millimeter that the centre of described grinding collet is provided with the degree of depth, and described groove flies out when being used for fixedly grinding head and preventing the grinding head motion, and the described intake chute that is located at the grinding head centre is rectangle.
The described inlet channel that is located in axle center is the cross through hole, and described transfusion ring is fixed installation, and the inlet opening that is located at transfusion ring side is radially offering along axle center.
The beneficial effects of the utility model are: the utility model is simple in structure, design is ingenious rationally, its grinding and polishing dish is cooling through the abrasive disk surface, the cooling fluid grinding and polishing process of dissociating, the cooling fluid on grinding and polishing chassis of flowing through can in time be taken away the heat that each zone of abrasive disk is gathered, play good cooling effect, thereby improve part processed finished products rate and efficiency.
Description of drawings
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is perspective view of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
The specific embodiment
with reference to Fig. 1, Fig. 2, interior cooling grinding and polishing device, comprise the bearing block 1 that is installed with bearing, described bearing is provided with main shaft, main shaft is connected with axle center 2, be fixed with in the upper end of described main shaft and grind collet 3, grind on collet 3 four the stainless steel thimbles 4 that are used for increasing abrasive disk spin friction power that distributing, on described grinding collet 3, grinding head 5 also is installed, the centre of described grinding head 5 is provided with intake chute 51, offer inlet channel 21 in described axle center 2, described intake chute 51 and inlet channel 21 and be located at inlet opening 61 mutual conduction of transfusion ring 6 sides.
As the optimization of above-mentioned embodiment, it is the groove of 1 millimeter that the centre of described grinding collet 3 is provided with the degree of depth, and described groove flies out when being used for fixedly grinding head 5 and preventing grinding head 5 motion, and the described intake chute 51 that is located in the middle of grinding head 5 is rectangle.
As the further optimization of above-mentioned embodiment, the described inlet channel 21 that is located in axle center 2 is the cross through hole, and described transfusion ring 6 is fixed installation, and the inlet opening 61 that being located at transfusion ring 6 sides is 2 radially offer along axle center.
This product in use, first on the inlet opening 61 of transfusion ring 6, water pipe is installed, make cooling water enter the chamber section in axle center 2 from the inlet opening 61 of transfusion ring 6, enter and grind collet 3 by the cross through hole 21 in axle center 2 again, then cooling water enters the grinding head 5 of machining state, flow out by intake chute 51 finally, thereby take away a large amount of heats.
In addition, the utility model is not limited to above-mentioned embodiment,, as long as it reaches technique effect of the present utility model with essentially identical means, all should belong to protection domain of the present utility model.
