Abstract
The utility model relates to an air-tightness test tool for an engine water pump. The air-tightness test tool comprises a frame, wherein the frame is provided with a plurality of hydraulic driving mechanisms, core plugs which are matched with each through hole on the engine water pump are respectively arranged in front of each hydraulic driving mechanism, and the core plugs are driven to do motion forwards to plug up each through hole. The air-tightness test tool can realize air-tight tests for the engine water pump and has properties of simple structure, high automation degree and good use effects.
Description
Technical field
The utility model relates to the airtight measurement jig of a kind of engine water pump.
Background technology
Engine water pump is the vitals in automobile cooling system, and its effect is that forced cooling water is circulated, to improve the engine cool effect.If leakage from water pump, will be directly connected to the task performance of engine, when serious, may cause starting machine burning cylinder pad even to damage.Therefore, when producing engine water pump, need to be tested the impermeability of workpiece, to guarantee the normal operation of engine.
Summary of the invention
The purpose of this utility model is to provide a kind of engine water pump airtight measurement jig, and this tool can carry out air tightness test to engine water pump, and simple in structure, and automaticity is high, and result of use is good.
For achieving the above object, the technical solution of the utility model is: the airtight measurement jig of a kind of engine water pump, comprise frame, described frame is provided with some hydraulic drive mechanisms, before each hydraulic drive mechanism, be respectively equipped with engine water pump on the plug that adapts of each through hole, block each through hole to drive described plug to travel forward.
Further, the quantity of described plug is identical with the quantity of through hole on engine water pump.
Further, the shape of described each plug respectively with described engine water pump on the shape of each through hole adapt.
Further, described frame is provided with the engine water pump detent mechanism.
Further, also comprise control circuit and the hydraulic oil feed system be connected with each hydraulic drive mechanism, described control circuit, after putting into engine water pump, is controlled the hydraulic oil feed system simultaneously to each hydraulic drive mechanism fuel feeding, to drive each plug feeding.
The beneficial effects of the utility model be by arrange with engine water pump on the plug that adapts of each through hole, and adopt hydraulic-driven, make each plug block each through hole on it after tool is put into engine water pump, with to the engine water pump air tightness test.Simultaneously, this jig structure is simple, and automaticity is high, and easy operating is practical.
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Embodiment
The airtight measurement jig of engine water pump of the present utility model, as shown in Figure 1, comprise frame 1, described frame 1 is provided with some hydraulic drive mechanisms 2, it is the oil hydraulic cylinder in the present embodiment, before each hydraulic drive mechanism 2, be respectively equipped with engine water pump 3 on the plug 4 that adapts of each through hole 5, block each through hole 5 to drive described plug 4 to travel forward.
The quantity of described plug 4 is identical with the quantity of through hole on engine water pump 5, the shape of described each plug 4 respectively with described engine water pump on the shape of each through hole 5 adapt.
For engine water pump is accurately located, also be provided with the engine water pump detent mechanism on described frame.
In order to improve automatization level, this tool also comprises control circuit 7 and the hydraulic oil feed system 6 be connected with each hydraulic drive mechanism 2, described control circuit 7 is after putting into engine water pump, control hydraulic oil feed system 6 simultaneously to each hydraulic drive mechanism 2 fuel feeding, to drive each plug 4 feedings.
During work, promote plug 4 with oil hydraulic cylinder and block 7 through holes of engine water pump, make the inside parts hollow parts form confined space.Implement airtight detection in conjunction with airtight detection instrument after filling certain atmospheric pressurized air.This tool can be according to the profile profile of part, the sealing property of simulation part under general assembly use state, and the accuracy of detection margin of error, in 2pa, is enough to detect high-precision product with this tool.
Be more than preferred embodiment of the present utility model, all changes of doing according to technical solutions of the utility model, when the function produced does not exceed the scope of technical solutions of the utility model, all belong to protection domain of the present utility model.
