The utility model provides a simple structure, detection convenience, the machining precision is high, and in whole car use, two rotary valve pass through limit structure, can be accurate open and close, guarantee and improved accuracy and the uniformity of two rotary valve helping hand diversion performance.
Description
Technical Field
The utility model relates to a take two commentaries on classics valves of integral type of flat side.
Background
At present, when a steering gear steers, the circumferential directions of a screw rod and a valve core of a rotary valve are limited by four grooves in a screw rod hole and four teeth on the valve core, oil passage holes in six grooves in the screw rod and an outer circle are positioned by four grooves in the screw rod hole to ensure circumferential post-processing, the four grooves of the screw rod are in the screw rod hole and are processed by an inner groove slotting tool, the processing and the detection are very difficult, the processing consistency is difficult to guarantee, the position accuracy of the inner six grooves and the oil passage holes in the back is influenced, the four teeth and the outer six grooves of the valve core are processed separately, the six grooves are clamped twice, the accuracy of the six grooves is greatly influenced, and the performance of the steering gear is influenced. Some large-tonnage engineering trucks need to carry out multi-axle power steering, but the arrangement space is limited, and the single-rotary valve type power steering gear obviously cannot meet the requirements.
Disclosure of Invention
The utility model aims at overcoming the above not enough, provide a simple structure, detect conveniently, the machining precision is high, in whole car use, two commentaries on classics valves pass through limit structure, can be accurate open and close, guarantee and improved accuracy and the uniformity of two commentaries on classics valve helping hand diversion performances.
The purpose of the utility model is realized through the following technical scheme: the integrated double-rotary valve with the flat sides comprises a screw and a valve core, wherein a connecting rod is arranged in the screw, one end of the connecting rod is connected with the valve core, the valve core is sleeved on the connecting rod and is arranged in the screw, the flat sides are arranged at one end of the screw, and matched grooves are formed in the outer circumference of the valve core and the flat sides on the screw.
Compared with the prior art, the utility model the advantage that has do: the centering adjustment device has the advantages that the structure is simple, the detection is convenient, the machining precision is high, and the centering performance of the rotary valve can be better ensured by adopting the flat square of the screw rod and the groove of the valve core for centering adjustment in the assembly process of the double-rotary valve; in the whole car use, the double-rotary-valve passes through limit structure, can be accurate open and close, guarantee and improved the accuracy and the uniformity of double-rotary-valve helping hand turning performance.
Description of the drawings:
FIG. 1 is a schematic structural view of the present invention;
reference numbers in the figures: 1-screw, 2-valve core, 3-connecting rod, 4-flat square and 5-groove.
The specific implementation mode is as follows:
in order to deepen the understanding of the present invention, the present invention will be further described in detail with reference to the following embodiments and the attached drawings, and the embodiments are only used for explaining the present invention, and do not constitute the limitation to the protection scope of the present invention.
Fig. 1 shows an embodiment of the present invention, which is an integrated double rotary valve with flat square: the integrated double-rotary valve with the flat sides comprises a screw rod 1 and a valve core 2, wherein a connecting rod 3 is arranged in the screw rod 1, one end of the connecting rod 3 is connected with the valve core 2, the valve core 2 is sleeved on the connecting rod 3 and is arranged in the screw rod 1, the flat sides 4 are arranged at one end of the screw rod 1, and the outer circumference of the valve core 2 and the flat sides 4 on the screw rod 1 are provided with matched grooves 5.
The utility model provides a simple structure, detection convenience, the machining precision is high, and the spacing flat square structure that adopts of screw rod and case at two flat squares of screw rod terminal surface processing, carry out circumferencial direction spacing with two recesses on the case step face. The flat square on the screw rod is processed outside the hole, so that the processing is simple and the detection is convenient. The same sides of the two flat squares are milled, so that the machining precision is high, the consistency is good, and the position precision of machining of the six grooves and the oil passage holes is high. When the valve core is processed, the two grooves and the outer six grooves of the valve core are processed by one-time clamping in the same procedure, so that the processing precision is ensured, the positioning and the detection are easy, and the valve core can adapt to large-scale industrialized production and quality control.
In the assembly process of the double-rotary valve, the flat side of the screw rod and the groove of the valve core are adopted for centering adjustment, so that the centering performance of the rotary valve can be better ensured; in the whole car use, the double-rotary-valve passes through limit structure, can be accurate open and close, guarantee and improved the accuracy and the uniformity of double-rotary-valve helping hand turning performance.
The applicant further states that the present invention is described by the above embodiments, but the present invention is not limited to the above embodiments, i.e. the present invention is not limited to the above embodiments, and the present invention can be implemented only by relying on the above methods and structures. It should be clear to those skilled in the art that any improvement of the present invention is to the present invention, and the addition of the equivalent replacement of the implementation method and the steps, the selection of the specific mode, etc. all fall within the protection scope and the disclosure scope of the present invention.
The utility model discloses not limited to above-mentioned embodiment, all adopt and the utility model discloses similar structure and method realize the utility model discloses all modes of purpose all are within the protection scope of the utility model.
