Description
Technical field
The utility model is related to a kind of split type cavity of resorption Oil Guide mechanism for hydraulic steering gear housing.
Background technology
At present, the cavity of resorption oil guiding hole of hydraulic steering gear housing generally makes monoblock type with housing, directly in shell during processing
The Oil Guide circular hole of the length of processing one on body.
The monolithic construction has shortcomings.For example, oil guiding hole is long, machining period is long, and efficiency is low, need to be added using special
Long drill bit, drill bit is easily broken, and hole precision is low, easily bores oblique, to ensure wall thickness, and aperture is difficult to do big, produces greater back-pressure, hole depth is very
Deep, crudy is difficult detection in hole, blind hole easily occurs, hole root burr is not easily cleaned, and influences the cleannes of fluid.
Utility model content
It is long for the cavity of resorption oil guiding hole and oil guiding hole present in housing of the hydraulic steering gear housing that overcomes monoblock type, plus
Work man-hour is long, and efficiency is low, need to use special lengthening drill bit, and drill bit is easily broken, and hole precision is low, easily bores oblique, to ensure wall thickness, aperture is very
Difficulty is done greatly, produces greater back-pressure, and hole depth is very deep, and crudy is difficult detection in hole, blind hole easily occurs, hole root burr is difficult clearly
Reason, influences the cleannes shortcomings of fluid, and the utility model provides a kind of split type cavity of resorption for hydraulic steering gear housing
Oil Guide mechanism with eliminate at present use technology defect.
The utility model solves the technical scheme that its technical problem used：A kind of point for hydraulic steering gear housing
Body formula cavity of resorption Oil Guide mechanism, including the blocking of housing, taper thread, self sealss oil guide pipe and upper lid, housing afterbody are machined with oil guiding hole,
Communicated with housing cavity of resorption, taper thread is processed into oil guiding hole one end, blocked by taper thread and seal aperture, the other end is a diameter
Slightly larger than the stepped hole of oil guiding hole, for installing self sealss oil guide pipe, the upper lateral edges of lid one have a boss, and boss bottom surface is processed
Oil guide pipe fixed seat, center processes oil guiding hole, and self sealss oil guide pipe is a thin-wall steel tube, and at steel pipe two ends, end face is molded with
Rubber packing material, self sealss oil guide pipe one end is fitted into housing afterbody fixed seat, and the other end loads upper lid oil guiding hole fixed seat,
By the fastening between upper lid and housing, oil guide pipe is firmly fixed in two, and the rubber packing material at oil guide pipe two ends
Sealing function is played in the interference deformation of generation.
The beneficial effects of the utility model are to provide a kind of split type cavity of resorption Oil Guide machine for hydraulic steering gear housing
Structure, with eliminate at present use technology defect, have the following advantages that：
1st, using split-type structural, housing does not reprocess elongated hole, and is changed to process short and small fixed seat in afterbody, simplifies
Technique, high in machining efficiency, precision is easily controllable, and machined burrs are easy to repair；
The 2nd, self sealss oil guide pipe is installed, oil guiding hole aperture can be increased, the back pressure produced during oil was reduced, having for oil pressure is improved
Imitate utilization rate；
3rd, it is connected, then by the fastening between upper lid and housing, oil guide pipe is firmly fixed with fixed seat using oil guide pipe
In fixed seat, assembling is simple；
4th, the rubber packing material of oil guide pipe both ends of the surface can play good sealing effectiveness.
Brief description of the drawings
Fig. 1 is the split type cavity of resorption Oil Guide mechanism scheme of installation of hydraulic steering gear housing；
Fig. 2 is close-up schematic view at Fig. 1 A；
Fig. 3 is close-up schematic view at Fig. 1 B；
Fig. 4 is self sealss oil guide pipe schematic diagram；
Fig. 5 is the close-up schematic view at Fig. 4 C.
Part, position and numbering in figure：Housing 1, taper thread block 2, self sealss oil guide pipe 3, upper lid 4.
Embodiment
【Embodiment】
Steering gear first loads self sealss oil guide pipe 3 in the fixed seat of the afterbody of housing 1, then by upper lid 4 in assembling
Fixed seat on boss is aligned with the other end of self sealss oil guide pipe 3, and upper lid 4 loaded into housing 1, and blending bolt is by upper lid 4 and shell
Body 1 is locked, and finally blocking 2 with taper thread again blocks the other end of the afterbody fixed seat of housing 1.When steering gear work, cavity of resorption is
During high pressure chest, fluid flows into the cavity of resorption of housing 1 from the oil guiding hole of upper lid 4 through self sealss oil guide pipe 3, when epicoele is high pressure chest,
The cavity of resorption fluid of housing 1 flows into the oil guiding hole of upper lid 4 further through self sealss oil guide pipe 3.
