Description
Technical field
The utility model relates to a kind of clamping device, is in particular a kind of clamping device detecting for automobile oil nozzle.
Background technology
In automobile industry, often higher to the requirement of its parts, especially require especially strictly for the core component of its engine.And atomizer is as the fuel input port of engine, the fuel feeding of its each beat has strict demand, cross make at most to burn insufficient, final unnecessary fuel causes environmental pollution and energy waste by exhaust emissions, cross the power supply deficiency that makes at least engine, the performance of engine cannot fully demonstrate.Therefore in automobile industry, need to carry out strict detection to this atomizer, thereby the distributive value of its each beat accurately be measured and made it to reach standard.
Existing detection mode is manually atomizer clamping to be positioned in detection platform, and be electrically connected with the control system of detection platform, restart atomizer simulated automotive driving process by beat oil spout, finally by checkout equipment, distributive value is measured.Obviously, in this existing detection mode, its time spending on clamping location is far longer than the time that instrument detects, therefore make the inefficiency detecting, and by the fixing atomizer of this manual mode clamping, its uniformity is poor, this also remote-effects the accuracy of detection to atomizer, this is not also obviously to be inconsistent with the high standard high-precision requirement of automobile industry.In addition, fluid volume is different along with variations in temperature, therefore for the high accuracy that detects for the oil temperature of above-mentioned fluid be need to carry out strict thermostatically controlled, the fluid in fuel tank being carried out to temperature control makes it consistent with the engine temperature of running condition of automobile, and be that the heat exchange lasting with the external world changes when the fluid of constant temperature in fuel tank is circulated to its oil temperature while detecting on checkout equipment by atomizer, that is to say, constant temperature fluid this process from fuel tank to checkout equipment with extraneous time of contact longer its oil temperature change greatly, accuracy of detection is poorer.Be not difficult to find out thus, the precision that the manual mode clamping of prior art not only makes the efficiency uniformity difference low, that detect detecting cause is poor, thereby and because the long oil temperature that makes of its clamping process time interval changes the low precision that greatly finally makes detection.
Utility model content
The technical problems to be solved in the utility model is, thereby a kind of clamping device detecting for automobile oil nozzle that detection efficiency is high and accuracy of detection is high that makes that can realize automated exchanged cutter location is provided.
Technical solution of the present utility model is, provide a kind of clamping device detecting for automobile oil nozzle with following structure: it comprises bearing frame, be located at the support on described bearing frame and be installed on the clamping device for clamping atomizer on this support, it is characterized in that: it also comprises installing plate and is located at the cylinder for driving installing plate to move up and down along atomizer axis direction on bearing frame, described installing plate is fixedly connected with the piston rod of this cylinder, and on this installing plate, the position corresponding with described atomizer is provided with up connection atomizer and checkout equipment, the oil connection of descending disengagement atomizer and checkout equipment, between described oil connection and checkout equipment, be connected by detecting oil pipe.
Operation principle of the present utility model is: first, atomizer is put into clamping device, again by air cylinder driven piston rod movement, drive installing plate is up, the oil connection corresponding with described atomizer is communicated with successively with exercising atomizer, oil connection, detection oil pipe and checkout equipment on installing plate thus, thereby carry out the detection of atomizer, after detecting, piston rod resets under the driving of cylinder, installing plate is descending, oil connection and atomizer are thrown off thus, and the automatic clamping that completes by that analogy whole atomizers detects.
Adopt above structure, the utility model compared with prior art has the following advantages: first, operating personnel only need to put into clamping device by atomizer, therefore more manually grip and be communicated with institute's spended time still less, detection efficiency is improved thus, secondly atomizer drives the up compression of oil connection connection with being communicated with by cylinder of oil connection, compared with manual mode fix and the uniformity that is communicated with better, while is because the time interval of the upper and lower clamping in centre that front and back atomizer detects shortens, so the variations in temperature of the fluid in atomizer is less, detect more accurate.
As a kind of improvement of the present utility model, between described bearing frame and support, be provided with the guide pillar for the installing plate moving up and down is led, described installing plate is slidably matched by the first through hole and guide pillar provided thereon.Guide pillar is set and can makes the installing plate accurately location that moves up and down in process, make its oil connection can accurately aim at atomizer.
Preferred as one, described guide pillar, clamping device, oil connection be two identical compositions of each freedom all, and these two guide pillars, two clamping devices and two oil connections are all separately along cylinder piston rod place axial location symmetry.The two cover oil connections that left and right distributes and clamping device can be realized two atomizers and detect simultaneously, the detection efficiency doubling.
As another kind of improvement of the present utility model, described cylinder is fixed on a side contrary with installing plate on described bearing frame, and bearing frame is provided with the second through hole that runs through this bearing frame and be connected with installing plate for piston rod.Because testing staff all stands, therefore the space of bearing frame below is not well utilized, and is symmetrical arranged with miscellaneous part by cylinder being arranged on to bearing frame below, and not only layout is more reasonable, and effectively utilizes the space of bearing frame below.
Further, be also provided with demister on described installing plate, a side of described demister is fixed and is communicated with one end of oil connection, and the opposite side of this demister is connected with detection oil pipe.Due to atomizer ejection be a large amount of vaporific fluid, the vaporific fluid of understanding some that naturally condenses does not flow into checkout equipment, therefore all converts vaporific fluid to liquid by demister, improves the degree of accuracy of detection.
Preferred as one, between described demister and installing plate, be also provided with spring, one end and the demister of this spring are fixed, and its other end and installing plate are fixed.Can on installing plate, exercise by spring is set the instantaneous reduction impulsive force that oil connection is communicated with atomizer, compress described oil connection and atomizer by spring force, make sealing effectiveness better simultaneously.
