Abstract
The utility model provides an it is top to repair center lapping, includes and still includes the slot by the centre head. The utility model discloses an improve the standard is top, set up the slot on the apical centre head of standard, its ditch trough rim is the edge, and debris such as the adnexed smear metal of member centre bore inner wall, residue, grit, iron rust can automatic be scraped to this edge to overcome the not enough of prior art, make the member behind the abrasive machining meet the requirements.
Description
Technical field
The utility model belongs to machine tool auxiliary device technical field, and being specifically related to one, to repair center lapping top.
Background technology
Lathe is when processing rod member, meeting movement presss from both sides fixed beam, and drive it to rotate by lathe, in order to avoid in the process of processing rod member, rock because of the rotation of rod member, ensure precision and the axiality of rod member, capital is installed at lathe tail end and is toply withstood rod member, when processing rod member, toply not rotate, but along with the rotation of rod member, top past rod member centre bore inner end is stretched into, withstood until top, as shown in Figure 2, firm effect is reached to rod member, its stress point is made to keep same level line, uniform force, reach precision and axiality requirement, thus process shape, the rod member be of the required size.
Rod member is when heat-treating, and usually can cause sudden and violent skin phenomenon because the heat time is long, namely produce oxide skin, oxide skin can be attached to the center bore inner wall of part; Carrying out in the process of machining to part, the chip of generation probably enters the centre bore of part, and is attached to center bore inner wall; In addition, put and also can produce iron rust for a long time, also have other foreign material such as grit unavoidably and enter centre bore and be attached to its inwall, because of this type of reason, when carrying out grinding to rod member, because rod member center bore inner wall is attached with foreign material, cause centre bore and grinding machine standard top between can not fit tightly because there is gap, do not reach the effect of firm rod member, there is irregular beating and occur overproof in final part grinding position, and then precision and the axiality requirement of part can not be met, make the shape of the rod member after processing, size is undesirable and scrap.
Utility model content
The utility model, for the technical problem of above-mentioned existence, provides one to repair center lapping top, described top can automatic scraping except center bore inner wall attachment foreign material.
In order to solve the problems of the technologies described above, the utility model provides following technical scheme: it is top that one repaiies center lapping, comprises centre head, and described centre head is taper, is provided with groove on the surface of centre head, and the ditch trough rim of described groove is seamed edge.
Operation principle of the present utility model and beneficial effect are: when carrying out grinding to rod member, can be withstood with top, make it firm, rod member and top between relative motion, in this process, seamed edge on top carries out scraping to the inwall of rod member centre bore, wipe the foreign material of center bore inner wall attachment off, smoothing is carried out to center bore inner wall, ensure to fit tightly between top and centre bore, thus reach the effect of firm rod member, meet precision and the axiality requirement of rod member, make the shape of the rod member after processing, be of the required size.Fallen in groove by the foreign material scraped away and pile up.
Further, described groove is linear pattern, screw type or S type, and the seamed edge of the groove of these three kinds of shapes can reach the foreign material striking off center bore inner wall, center bore inner wall is carried out to the effect of smoothing.
Further, the starting point of described groove is the summit of centre head, and terminal is positioned at the end of centre head, and such design can solve when foreign material fill groove, the problem that foreign material can be discharged from the end of centre head automatically.
Further, the opening of described groove increases from the summit of centre head gradually to end, when foreign material are discharged automatically, increases the space of foreign material activities, reduces resistance, the cleaning after also easy to use.
Further, described groove has 1 ~ 3 road, under the prerequisite not affecting centre head internal structure stability, arranges 1 ~ 3 to groove, and the area of the centre bore making groove corresponding is large as far as possible, can shorten the smoothing time to centre bore like this, improve scraping efficiency.
Further, described linear type groove has twice, specular is kept between described twice groove, being designed with like this is beneficial to foreign material and center bore inner wall because of cancelling out each other between fricative active force, avoid adding man-hour to rod member, foreign material cause rod member unbalance stress and can not reach dimensional requirement.
Further, described centre head there is the semicircle conical surface that complete, during grinding rod member, complete half-conical faces up, meeting toply on gravity direction has a larger receiving area, bears the gravity of rod member, reduces because holding capacity is large, the little top breakage caused of lifting surface area, extends top service life.
Accompanying drawing explanation
Fig. 1 is that the utility model repaiies the top schematic diagram of center lapping;
Fig. 2 is the schematic diagram that the utility model repaiies the top firm rod member of center lapping;
Fig. 3 is the top schematic diagram of prior art standard.
Detailed description of the invention
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Reference numeral: rod member 1, centre bore 2, standard top 3, groove 4, seamed edge 5, repaiies center lapping top 6.
Embodiment:
As shown in Figures 1 and 3, by standard top 3, centre head surface along standard top 3 grinds twice linear type groove 4 from the summit of centre head to end, specular is kept between twice linear type groove 4, described centre head there is the semicircle conical surface that complete, during grinding rod member 1, complete half-conical faces up; The opening of linear type groove 4 increases from the summit of centre head gradually to end.
As shown in Figure 2, rod member 1 is when carrying out grinding, the centre bore 2 repairing the seamed edge 5 pairs of rod members 1 on center lapping top 6 carries out scraping, wipe the foreign material of centre bore 2 inwall attachment off, smoothing is carried out to the inwall of centre bore 2, make to repair between center lapping top 6 and the centre bore 2 of rod member 1 and fit tightly, fallen in groove 4 by the foreign material scraped away and pile up, avoid in grinding process because the position of the foreign material of center bore inner wall attachment changes, cause irregular the beating in rod member 1 grinding position and occur overproof, make the rod member 1 processed not meet standard and the technical problem such as to scrap and occur, thus make the rod member 1 processed meet shape and dimensional requirement.
Above-mentioned linear type groove also can be designed to screw type or S type, ditch trough rim is also seamed edge, and the starting point of groove and terminal are summit and the end of centre head respectively, the opening of groove is also increase gradually from the summit of centre head to end, but screw type and S type groove discharge the performance of foreign material automatically not as linear type groove.
For a person skilled in the art; under the prerequisite not departing from the utility model structure; can also make some distortion and improvement, these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.
