The motion testing machine is characterized by comprising a machine rack, a base plate disposed on the machine rack, a lower clamp disposed on the base plate, a supporting rack disposed on the machine rack, an upper clamp which is disposed on the supporting rack and which is opposite to the lower clamp, a main cylinder which is disposed on the supporting rack and which is used for driving the upper clamp, a gas storage tank which is disposed in the machine rack and which delivers gas to a device to be tested via a conduit, a pressure increasing valve connected with the gas storage tank, an electrical control cabinet which is disposed on the machine rack, which is connected with the storage tank and the main cylinder, and which controls the operation of the storage tank and the main cylinder, an operation panel which is connected with the electrical control cabinet and which inputs control commands, a display instrument which is connected with the electrical control cabinet and which outputs tested results, a flowmeter which is disposed on the supporting rack and at the oil return opening of the pressure limiting valve to be tested and which is used for testing the exhausted gas flow and outputting tested results to the display instrument to be displayed. Compared with a product in the prior art, the motion testing machine uses air as a testing medium and does not cause pollution on surrounding environment.
Description
Technical field
The utility model relates to a kind of engine oil pump pressure-limiting valve action test machine.
Background technology
Usually engine oil pump assembly has been assembled rear Performance Detection and adopted regularly sampling observation, i.e. the several products of every production extract a product performance test bed Performance Detection of advancing of packing into.Performance test bed floor area is large, and loading and unloading are inconvenient, tests a product time long, can not accomplish total detection.Because of with machine oil as tested media, test residual machine oil on rear engine oil pump assembly, be difficult to clean out, can cause certain pollution to surrounding environment, and easily cause when rear operation is coated with fluid sealant and come unstuck.
Summary of the invention
Fundamental purpose of the present utility model is to solve traditional shortcoming, does not adopt machine oil as tested media, avoids environmental pollution.
For realizing above purpose, the technical scheme that the utility model adopts is to provide a kind of engine oil pump pressure-limiting valve action test machine, it is characterized in that described engine oil pump pressure-limiting valve action test machine comprises: frame; Described frame is provided with base plate; Described base plate is provided with lower clamp; Bracing frame is located on described frame; Be provided with fixture on support frame as described above, described upper chucking position is with respect to described lower clamp; Master cylinder is located on support frame as described above, is used for driving upper clamp movement; Gas-holder is located in described frame, delivers the gas to equipment to be detected by conduit; Pressure charging valve connects described gas-holder; Electric control box is located at described frame, connects and controls described gas-holder, master cylinder work; Guidance panel connects described electronic control box, input of control commands; Displaying Meter connects described electronic control box, the output detections result; Flowmeter is located at the oil return opening place that is positioned at pressure limiting valve to be detected on support frame as described above, in order to the gas flow of detection discharge, and testing result is exported described Displaying Meter demonstration.
After having adopted technique scheme, the utility model compared with prior art adopts air to do tested media, can not pollute surrounding environment, tests also noresidue machine oil of rear engine oil pump assembly, causes in the time of can not being coated with fluid sealant to rear operation and comes unstuck.Reduce the production floor area, improve the output value of unit area.

Embodiment
Below in conjunction with the drawings and specific embodiments, to the engine oil pump pressure-limiting valve action test machine further description of proposition that the utility model adopts.
Please refer to Fig. 1, Fig. 2, the described engine oil pump pressure-limiting valve action test of the present embodiment machine comprises frame 1; Described frame 1 is provided with base plate 4; Described base plate 4 is provided with lower clamp 5; Bracing frame is located on described frame 1; Be provided with fixture 7 on support frame as described above, described upper fixture 7 positions are with respect to described lower clamp 5; Master cylinder 10 is located on support frame as described above, is used for driving upper fixture 7 motions; Gas-holder 2 is located in described frame 1, delivers the gas to equipment to be detected by conduit, and both the lubricating oil pump assembly 6; Pressure charging valve 3 connects described gas-holder 2; Electric control box 11 is located at described frame 1, connects and controls described gas-holder 2, master cylinder work 10; Guidance panel 8 connects described electronic control box 11, input of control commands; Displaying Meter 9 connects described electronic control box 11, the output detections result; Flowmeter is located at the oil return opening place that is positioned at pressure limiting valve to be detected on support frame as described above, in order to the gas flow of detection discharge, and testing result is exported described Displaying Meter demonstration.
In the present embodiment, the course of work of engine oil pump pressure-limiting valve action test machine is as follows, detects by the go-no go gauge principle.Pressure limiting valve opening pressure has the bound area requirement, at first with clamping product on fixture, then the pressure limiting valve assembly is applied low-pressure compressed air (opening pressure lower limit), air mass flow by flowmeter detectability pressure valve oil return opening place, again the pressure limiting valve assembly is applied high pressure air (opening pressure higher limit), by the air mass flow at flowmeter detectability pressure valve oil return opening place, whether the data equipment automatic analysis and judgment pressure limiting valve assembly that detects according to flowmeter at last is qualified.
Above in order to illustrate and to describe to the description of the utility model preferred embodiment, be not want the utility model limit or be confined to disclosed concrete form, obviously, may make many modifications and variations, these modifications and variations may be obvious to those skilled in the art, within should being included in the scope of the present utility model by the appended claims definition.
