Abstract
The invention discloses a fixed-depth machining structure of an oil seal groove, and aims to solve the problem that the consistency of machining depth of each oil seal groove cannot be guaranteed in the prior art. The fixed-depth machining structure of the oil seal groove comprises an oil seal countersink, wherein a rotary bearing sleeve is arranged on the outer ring of the oil seal countersink; a ball bearing is arranged in the rotary bearing sleeve; a cover body is arranged on an end part of the rotary bearing sleeve; the rotary bearing sleeve is provided with external threads; a limiting outer sleeve is in threaded connection with the rotary bearing sleeve; a limiting sleeve adjusting wire ring is arranged on the outer ring of the rotary bearing sleeve; one side of the limiting sleeve adjusting wire ring is abutted against the end part of the limiting outer sleeve.
Description
Technical field
The present invention relates to oil sealing process technology, be specifically related to a kind of oil seal groove depthkeeping processing structure.
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 a circle oil seal groove on the surface of oil sealing, have higher requirement to the working depth of oil seal groove.At present, in the processing of oil seal groove, machined surface is usually adopted to carry out the working depth of positioning oil seal groove, namely after oil sealing countersink gets into oil sealing inside, using machined surface as benchmark, after oil sealing countersink exits, machined surface is the working depth of oil seal groove to the distance of oil sealing countersink termination.Above-mentioned localization method often cannot ensure the uniformity of each oil seal groove working depth, and machining accuracy is poor, affects quality.
Summary of the invention
The invention provides a kind of oil seal groove depthkeeping processing structure, cannot ensure to solve prior art the problem that each oil seal groove working depth is consistent.
This programme is as follows: oil seal groove depthkeeping processing structure, comprise oil sealing countersink, rotating shaft bearing sleeve is provided with in oil sealing countersink outer ring, rotating shaft bearing sleeve is built with ball bearing, be provided with lid in the end of rotating shaft bearing sleeve, swivel bearing is arranged with external screw thread, and a spacing overcoat is connected with swivel bearing external threading, be provided with stop collar adjustment wire ring in the outer ring of rotating shaft bearing sleeve, the stop collar adjustment side of wire ring and the end of spacing overcoat offset.
During oil sealing countersink processing oil sealing groove of the present invention, oil sealing countersink, ball bearing synchronous rotary, rotating shaft bearing sleeve, lid, spacing overcoat and stop collar adjustment wire ring maintain static.
Because spacing overcoat is connected with swivel bearing external threading, therefore regulate the axial location of spacing overcoat by rotary stopper overcoat, then by the locking of stop collar adjustment wire ring.Before processing oil sealing groove, limited the working depth of oil sealing countersink by the distance between spacing overcoat end face and oil sealing countersink termination, after each swivel feeding of oil sealing countersink to this designated depth, just stop processing, the uniformity of each oil seal groove working depth can be guaranteed, the accuracy of processing.
Further, in order to more stable support oil sealing countersink, arrange two ball bearings, be provided with bearing inner race spacer between two ball bearings, bearing inner race spacer is locked by the first lock-screw and oil sealing countersink.
Further, also comprise thrust bearing, side and the ball bearing of thrust bearing offset, and opposite side is provided with bearing location adjusting sleeve, and bearing location adjusting sleeve is locked by the second lock-screw and oil sealing countersink, and the bearing location cylindrical of adjusting sleeve and the inner ring of lid offset.By the axial gap of bearing location adjusting sleeve adjustable thrust bearing, locked by the second lock-screw after adjustment.
Further, what be connected with rotating shaft bearing sleeve to make lid is more firm, and lid is by the 3rd lock-screw and swivel bearing cover locking.
Accompanying drawing explanation
Fig. 1 is the structural representation of the embodiment of the present invention.
In figure, H represents the distance between spacing overcoat end face and oil sealing countersink termination.

Embodiment is substantially as shown in Figure 1: the oil seal groove depthkeeping processing structure of this enforcement, comprise oil sealing countersink 1, rotating shaft bearing sleeve 3 is provided with in oil sealing countersink 1 outer ring, rotating shaft bearing sleeve 3 is built with two ball bearings 4, between two ball bearings 4, be provided with bearing inner race spacer 5, bearing inner race spacer 5 is locked with oil sealing countersink by the first lock-screw 6.
Lid 8 is provided with in the end of rotating shaft bearing sleeve 3, lid 8 is locked with rotating shaft bearing sleeve 3 by the 3rd lock-screw 9, the longitudinal section of lid 8 is L-shaped, the end of lid 8 and thrust bearing 10 ball bearing that is common and outside offset, the opposite side of this thrust bearing 10 is provided with bearing location adjusting sleeve 11, bearing location adjusting sleeve 11 is locked with oil sealing countersink 1 by the second lock-screw 12, and the bearing location cylindrical of adjusting sleeve 11 and the inner ring of lid 8 offset.
In the present embodiment, rotating shaft bearing sleeve 3 is provided with external screw thread, and spacing overcoat 2 is threaded with rotating shaft bearing sleeve 3, and be provided with stop collar adjustment wire ring 7 in the outer ring of rotating shaft bearing sleeve 3, the stop collar adjustment side of wire ring 7 and the end of spacing overcoat 2 offset and lock spacing overcoat 2.
The feeding depth of the distance in the present embodiment between spacing overcoat 2 end face and oil sealing countersink 1 termination and oil sealing countersink processing oil sealing groove.
Above-described is only embodiments of the invention, 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 structure of the present invention, some distortion and improvement can also be made; these also should be considered as protection scope of the present invention, and these all can not affect effect of the invention process and practical applicability.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.
