Description
Technical field
The invention patent relates to a kind of split type cavity of resorption Oil Guide mechanisms for hydraulic steering gear shell.
Background technology
Currently, the cavity of resorption oil guiding hole of hydraulic steering gear shell usually makes monoblock type with shell, directly in shell when processing
The Oil Guide circular hole of one length of processing on body.
The monolithic construction has shortcomings.For example, oil guiding hole is long, machining period is long, and efficiency is low, need to use special add
Long drill bit, drill bit is easily broken, and hole precision is low, easily bores tiltedly, to ensure that wall thickness, aperture are difficult to do greatly, generates greater back-pressure, hole depth is very
Deep, processing quality is not easy to detect in hole, blind hole easily occurs, hole root burr is not easily cleaned, and influences the cleannes of fluid.
Patent of invention content
In order to overcome monoblock type hydraulic steering gear shell cavity of resorption oil guiding hole and the oil guiding hole present in shell it is long, add
Work working 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 tiltedly, to ensure wall thickness, aperture is very
Difficulty is done greatly, generates greater back-pressure, hole depth is very deep, and processing quality is not easy to detect in hole, blind hole easily occurs, and hole root burr is not easy clearly
Reason, influences the cleannes shortcomings of fluid, patent of the present invention provides a kind of split type cavity of resorption for hydraulic steering gear shell
Oil Guide mechanism is to eliminate the defect of current used technology.
Technical solution is used by patent of the present invention solves its technical problem：A kind of point for hydraulic steering gear shell
Body formula cavity of resorption Oil Guide mechanism, including shell, taper thread block, self sealss oil guide pipe and upper cover, shell tail portion are machined with oil guiding hole,
It is communicated with shell cavity of resorption, taper thread is processed into oil guiding hole one end, is blocked by taper thread and seals aperture, and the other end is a diameter
Slightly larger than the stepped hole of oil guiding hole, for installing self sealss oil guide pipe, upper cover one side edge has a boss, boss bottom surface to process
Oil guide pipe fixed seat, center process oil guiding hole, and self sealss oil guide pipe is a thin-wall steel tube, is molded in steel pipe both ends end face
Rubber packing material, self sealss oil guide pipe one end are fitted into the fixed seat of shell tail portion, and the other end is packed into upper cover oil guiding hole fixed seat,
By the fastening between upper cover and shell, oil guide pipe is firmly fixed in two, and the rubber packing material at oil guide pipe both ends
Sealing function is played in the interference deformation of generation.
The advantageous effect of patent of the present invention is to provide a kind of split type cavity of resorption Oil Guide machine for hydraulic steering gear shell
Structure is had the following advantages that with eliminating the defect of used technology at present：
1, using split structure, shell does not reprocess elongated hole, and is changed to process short and small fixed seat in tail portion, simplifies
Technique, high in machining efficiency, precision is easily controllable, and machined burrs are easy to repair；
2, self sealss oil guide pipe is installed, oil guiding hole aperture can be increased, reduced the back pressure generated when oil, that improves oil pressure has
Imitate utilization rate；
3, it is connect with fixed seat using oil guide pipe, then by the fastening between upper cover and shell, oil guide pipe is firmly fixed
In fixed seat, assembly is simple；
4, the rubber packing material of oil guide pipe both ends of the surface can play good sealing effect.

Part, position and number in figure：Shell 1, taper thread block 2, self sealss oil guide pipe 3, upper cover 4.
Specific implementation mode
【Embodiment】
Self sealss oil guide pipe 3 is packed into the fixed seat of 1 tail portion of shell, in assembly then by upper cover 4 by steering gear first
Fixed seat on boss and 3 other end of self sealss oil guide pipe are packed into shell 1 to just, by upper cover 4, and blending bolt is by upper cover 4 and shell
Body 1 is locked, and finally blocking 2 with taper thread again blocks the other end of 1 tail portion fixed seat of shell.When steering gear works, cavity of resorption is
When high pressure chest, fluid flows into the cavity of resorption of shell 1 from the oil guiding hole of upper cover 4 through self sealss oil guide pipe 3, when epicoele is high pressure chest,
1 cavity of resorption fluid of shell flows into the oil guiding hole of upper cover 4 further through self sealss oil guide pipe 3.
