Problems solved by technology

The reason why there is no quick and simple method to detect is that the position of the pressure feedback hole is relatively deep, and ordinary inspection tools cannot reach here, but the detection of this feedback hole is essential in the process of pump body processing A process that, especially for remanufactured pump bodies, creates many problems for production

Embodiment Construction

[0011] The structure of the remanufactured pump body pressure feedback hole penetration detection device of the present invention is as follows: figure 1 and figure 2 As shown, there is a groove 5 on the hollow base 2, and an air outlet 3 is provided at the groove 5, and an external thread 1 for connecting the air gun is provided on the upper part of the base 2, and the positions of the groove 5 and the air outlet 3 depend on the size Cooperate to achieve the purpose of airtight sealing; the air outlet hole 3 and the groove 5 around it form an air flow, so as to adapt to the pressure feedback hole in all directions.

[0012] The detection principle of the pressure feedback hole of the pump body is as follows: image 3 As shown, connect the air gun with the device and insert it into the bottom of the valve hole of the pump body 6. At this time, the air outlet hole 3 of the device is on the same level as the pressure feedback hole 4 of the pump body; turn on the switch of the ...

Abstract

The invention discloses a penetration inspection device of pressure feedback holes of a rebuilt pump body. A groove is formed in a hollow base body; an air outlet is formed in the groove; outer thread for connecting an air gun is formed in the upper part of the base body. The penetration inspection device of the pressure feedback holes of the rebuilt pump body is simple in structure, convenient to use, high in inspection efficiency and low in manufacturing cost; the position of the air outlet can be adjusted according to the positions of the pressure feedback holes, so that multiple inspection instruments are manufactured to inspect pressure feedback holes of rebuilt pump bodies of different types; if a feedback hole is blocked, high pressure air can be used for removing foreign matters.

Description

technical field [0001] The invention relates to the technical field of detection and troubleshooting of a pressure feedback hole of a vane-type hydraulic steering booster pump, in particular to the technical field of detection and troubleshooting of whether the pressure feedback hole is penetrated during the remanufacturing process of a vane-type hydraulic steering booster pump body. Background technique [0002] In order to reduce the failure probability of the entire steering pump, it is necessary to accurately detect this feedback hole, which not only improves the processing efficiency of the subsequent sequence, but also reduces the failure rate of the product due to this feedback hole. At present, there is no simple and fast method or device for whether the pressure feedback hole with an internal diameter of 1 mm in the hydraulic power steering pump is connected. The reason why there is no quick and simple method to detect is that the position of the pressure feedback h...
