Description
Technical field
The utility model relates to oil sealing process technology, is specifically related to a kind of depthkeeping processing oil sealing groove frock.
Background technology
Oil sealing is used to the circular element of sealing lubricating oil, and its principle is isolated with parts of exerting oneself by the parts needing in drive disk assembly to lubricate, and prevents oil seepage.Oil sealing is generally used for the positions such as engine crankshaft, gearbox, differential mechanism, shock absorber and vehicle bridge.
Usually there is the oil seal groove of a ring shape on the surface of oil sealing, generally have higher requirement to the working depth of oil seal groove.At present, the machined surface of usual oil sealing carrys out the working depth of positioning oil seal groove, and when the position limiting structure top namely on oil sealing countersink is to oil sealing machined surface, oil sealing countersink gets into and requires the degree of depth.Because position limiting structure directly contacts with machined surface, therefore Problems existing is, the position limiting structure on oil sealing countersink is very easy to the machined surface scratching oil sealing.
Utility model content
The utility model provides a kind of depthkeeping processing oil sealing groove frock, to solve the problem that in the processing of existing oil seal groove, oil sealing machined surface easily scratches.
This programme is as follows: depthkeeping processing oil sealing groove frock, comprise oil sealing countersink, spacing overcoat is socketed with at the cylindrical of oil sealing countersink, spacing overcoat by housing screw and oil sealing countersink fastening, be provided with the mounting groove of ring-type in the lower surface of spacing overcoat, be provided with spacing inner sleeve in mounting groove, mounting groove is stretched out in the outer end of spacing inner sleeve, be provided with location backing plate in the below of spacing inner sleeve, relatively with oil sealing countersink cutter head on the backing plate of location have through hole.
This programme operation principle is as follows: the spacing overcoat on oil sealing countersink and spacing inner sleeve form the position limiting structure on oil sealing countersink, and oil seal groove adds man-hour, and when the upper surface of location backing plate is pushed up in the lower end of spacing inner sleeve, oil sealing countersink gets into and requires the degree of depth, and cutter dallies.
The spacing overcoat of the utility model by housing screw and oil sealing countersink fastening, make the position more firm stable of spacing overcoat and spacing inner sleeve.By arranging location backing plate, during processing oil sealing groove, oil sealing countersink gets into and requires the degree of depth, and the position limiting structure on oil sealing countersink contacts with the upper surface of location backing plate, therefore can not impact the machined surface of oil sealing, can not scratch oil sealing machined surface.
Further, in order to the position making spacing inner sleeve is more firm, be also provided with back-up ring in spacing overcoat lower surface, medial surface and the spacing inner sleeve of back-up ring offset, back-up ring by screw and spacing overcoat fastening.
Further, being provided with in the both sides of through hole can the alignment pin of positioning oil seal.During processing oil sealing groove, by by the alignment pin on the backing plate of location, the dowel hole inserted on oil sealing positions location backing plate.
Further, the flange being connected to oil-seal outer of ring-type is had in the bottom surface of location backing plate.During processing oil sealing groove, flange is connected to the cylindrical place of oil sealing, location backing plate is played to the effect of location.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment;
Fig. 2 is the schematic top plan view of locating backing plate during Fig. 1 implements.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: oil sealing countersink 1, spacing overcoat 2, housing screw 3, spacing inner sleeve 4, back-up ring 5, screw 6, location backing plate 7, alignment pin 8, oil sealing workpiece 9, through hole 10.
Substantially as shown in figure 1 and 2, the present embodiment depthkeeping processing oil sealing groove frock, comprises the position limiting structure on oil sealing countersink 1, oil sealing countersink 1 and location backing plate to embodiment.Position limiting structure on oil sealing countersink 1 is specially: be socketed spacing overcoat 2 at the cylindrical of oil sealing countersink 1, spacing overcoat 2 is fastening with oil sealing countersink 1 by symmetrically arranged two housing screws 3, the mounting groove of ring-type is provided with in the lower surface of spacing overcoat 2, spacing inner sleeve 4 is installed in mounting groove, mounting groove is stretched out in the outer end of spacing inner sleeve 4, spacing overcoat 2 lower surface is provided with back-up ring 5, back-up ring 5 is fastening by screw 6 and spacing overcoat 2, spacing inner sleeve 4 upper end of the present embodiment has bending segment, medial surface and spacing inner sleeve 4 side of back-up ring 5 offset, the upper surface of back-up ring 5 and the bending segment of spacing inner sleeve 4 offset, to make the position of spacing inner sleeve 4 more firm.
In this enforcement, location backing plate 7 is provided with in the below of spacing inner sleeve 4, relatively with oil sealing countersink 1 cutter head on the backing plate 7 of location have through hole 10, when processing oil sealing groove, location backing plate 7 is placed on the machined surface of oil sealing workpiece 9, oil sealing countersink 1 gets into and requires the degree of depth, and the position limiting structure on oil sealing countersink 1 contacts with the upper surface of location backing plate 7, therefore can not scratch oil sealing machined surface.
In order to locate the position of backing plate 7, in the both sides of location backing plate 7 through hole, alignment pin 8 can be set, also can offer the flange of the be connected to oil-seal outer of ring-type in the bottom surface of location backing plate 7, as shown in Figure 2, the present embodiment preferably arranges alignment pin 8 respectively in the both sides of location backing plate 7 through hole.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; 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.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
