Abstract
The utility model discloses a kind of novel mill inner-hole frock, comprise axle, briquetting and nut, by using two ringfeder location, and spacer is set between two ringfeders, make ringfeder be positioned at suitable position, inner hole of workpiece two, thus realize substantially simulating axis, when lower road mill endoporus, ensure that endoporus grinds with grinding allowance minimum, ensure that grinding machine process requirements.
Description
Technical field
The utility model relates to a kind of machinery processing apparatus, is specifically related to a kind of frock being applicable to pick cylinder mill endoporus.
Background technology
Pick cylinder is core texture part in pneumatic pick, and connect pick rod under upper undertaking valve actuating mechanism, piston wherein.Inner at pick cylinder, by the conversion of air valve height low-flow, driven plunger, constantly moves back and forth, and hits bit shank, reciprocating impact rock, reaches broken object.In pick cylinder mill endoporus process, the location of pick cylinder directly affects the quality of pick cylinder processing, and pick cylinder location is realized by fixture usually, but current fixture location endoporus axial distance is too near, during grinding machine cylindrical grinding, fixture can not simulate interior axially bored line completely, causes follow-up mill endoporus to scrap in a large number.
Utility model content
For the deficiencies in the prior art, the utility model aims to provide a kind of novel mill inner-hole frock, by using two ringfeder location, and spacer is set between two ringfeders, make ringfeder be positioned at suitable position, inner hole of workpiece two, thus realize substantially simulating axis, when lower road mill endoporus, ensure that endoporus grinds with grinding allowance minimum, ensure that grinding machine process requirements.
To achieve these goals, the utility model adopts following technical scheme:
A kind of novel mill inner-hole frock, comprise axle, ringfeder, sphere cover, briquetting and nut, above-mentioned each parts connect successively; Described mill inner-hole frock is provided with at least two ringfeders and at least two spheres overlap and spacer, connects successively between one of them ringfeder, one of them sphere cover, spacer, another ringfeder and another sphere cover; The other end of one of them ringfeder described connects described axle, and the other end of described another sphere cover connects described briquetting.
It should be noted that, use two ringfeder location, and spacer is set between two ringfeders, object is to make two ringfeders be positioned at inner hole of workpiece two correct position, realize substantially simulating axis, when lower road mill endoporus, contribute to realizing that endoporus grinds with grinding allowance is minimum, ensure that grinding machine process requirements.
As a kind of preferred version, the two ends of described axle are provided with centre bore and Double Tops point.Described centre bore and for cylindrical grinder Double Tops point location, the object arranged is, cylindrical grinding and with cylindrical location mill size endoporus before, can first with Double Tops point apotting spindle centre bore and carry out pick cylinder endoporus two ringfeder location, can ensure that inner hole grinding amount is even like this, eliminate that to be out of shape the stock removal brought inadequate, reduce the workload of internal grinder, improve working (machining) efficiency, product percent of pass improves greatly.
The beneficial effects of the utility model are:
1, two ringfeders are adopted to locate and add spacer, two ringfeders can be positioned at endoporus two correct position, ensure substantially to simulate axis, avoid, because fixture can not simulate interior axially bored line completely when fixture positioning workpieces endoporus axial distance too closely makes grinding machine cylindrical grinding, causing follow-up mill endoporus to scrap in a large number;
2, when lower road mill endoporus, ensure that endoporus grinds with grinding allowance minimum, ensure that grinding machine process requirements;
3, before mill endoporus, first pick cylinder endoporus two ringfeder location can be carried out with Double Tops point apotting spindle centre bore, can ensure that inner hole grinding amount is even like this, eliminate that to be out of shape the stock removal brought inadequate, reduce the workload of internal grinder, improve working (machining) efficiency, product percent of pass improves greatly.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below with reference to accompanying drawing, the utility model will be further described, it should be noted that, the present embodiment, premised on the technical program, give detailed embodiment and concrete operating process, but protection domain of the present utility model is not limited to the present embodiment.
As shown in Figure 1, a kind of novel mill inner-hole frock, comprise axle 1, briquetting 2 and nut 3, in addition, described mill inner-hole frock is provided with two ringfeders and two spheres overlap and spacer 6, and one of them ringfeder 41, one of them sphere cover 51, spacer 6, another ringfeder 42 and another sphere connect between overlapping 52 successively; The other end of one of them ringfeder 41 described connects described axle 1, and the other end of described another sphere cover 52 connects described briquetting 2.
Wherein, the two ends of described axle 1 are provided with centre bore 11 and 12.Described centre bore 11 and 12 is for cylindrical grinder Double Tops point location.
During use, first unclamp nut, pick jacket casing is connected in described mill inner-hole frock, then fastening nut, now ringfeder and sphere to be enclosed within the effect of nut and briquetting macropore in stretching pick cylinder and to reach radial location, then by axle two ends centre bore be positioned at cylindrical grinder two top on, now can start working.
It should be noted that, use two ringfeder location, and spacer is set between two ringfeders, object is to make two ringfeders be positioned at pick cylinder endoporus two correct position, realize substantially simulating axis, when lower road mill endoporus, contribute to realizing that endoporus grinds with grinding allowance is minimum, ensure that grinding machine process requirements.The centre bore at axle two ends can make cylindrical grinding and with before cylindrical location mill size endoporus, first carry out pick cylinder endoporus two ringfeder location with Double Tops point apotting spindle centre bore, can ensure that inner hole grinding amount is even like this, the stock removal that elimination distortion brings is inadequate, reduce the workload of internal grinder, improve working (machining) efficiency, product percent of pass improves greatly.
For a person skilled in the art, according to above technical scheme and design, various corresponding change and distortion can be made, and all these change and distortion all should be included within the protection domain of the utility model claim.
Claims (2)
1. a novel mill inner-hole frock, comprises axle, ringfeder, sphere cover, briquetting and nut, and above-mentioned each parts connect successively; It is characterized in that, described mill inner-hole frock is provided with at least two ringfeders and at least two spheres overlap and spacer, connects successively between one of them ringfeder, one of them sphere cover, spacer, another ringfeder and another sphere cover; The other end of one of them ringfeder described connects described axle, and the other end of described another sphere cover connects described briquetting.
2. the novel mill inner-hole frock of one according to claim 1, it is characterized in that, the two ends of described axle are provided with centre bore.
