Abstract

The invention belongs to device detection equipment, and in particular relates to a dry leak testing machine. The dry leak testing machine mainly comprises a vertical bracket, a longitudinal cylinder, a transverse cylinder and an airtight leak detector, wherein the vertical bracket comprises an upper workbench and a lower workbench by a fixing column; the airtight leak detector is arranged on the upper part of the workbench, and the longitudinal cylinder is fixed on the lower part; the lower workbench is provided with a bottom plate; an air duct is arranged in the bottom plate and is connected with the air outlet of the airtight leak detector via an air tube; one side of the transverse cylinder, which is arranged on the bottom plate, is fixed on the lower workbench; and the transverse cylinder piston of the transverse cylinder is provided with a sealing plug. The dry leak testing machine has the beneficial effects that a workpiece is fixed by the longitudinal cylinder; a through hole of a heat dissipation device is plugged and sealed by the transverse cylinder, and a large electronic device radiator is pressurized in a sealed mode so as to observe the air pressure situation of the airtight leak detector to determine whether the radiator is leaked. A test result is intuitive, accurate and efficient, and the quality of the electronic device radiator is greatly guaranteed.

Description

The dry type leakage tester

Technical field

The invention belongs to the device checkout equipment, relate in particular to a kind of dry type leakage tester.

Background technology

Large-scale electronic-device radiator has some heat radiation wings and is installed in the communicator of base station, the dial plate of communicator or button leak outside heating radiator, make and when cast radiator, on its sidewall, leave several through holes, have O-ring seal on the through hole, O-ring seal and dial plate and button closely cooperate to guarantee the leakproofness of heating radiator inside, but because its long term exposure is out of doors in the air, weather in the face of various complexity, if the poor sealing of heating radiator can cause the short circuit of inner electron device, and cause the premature damage of communicator.Therefore, the gas leakage of leaking to heating radiator detects extremely important, also not having at present special checkout equipment is the heating radiator that has dial plate hole or button hole to be leaked to leak gas detect, large-scale electronic-device radiator impermeability is detected becomes blank, can't adapt to requirement high-quality to product under the intense market competition.

Summary of the invention

The objective of the invention is to overcome the deficiency of above-mentioned technology, and provide a kind of simple in structure, test result is accurate, high efficiency dry type leakage tester.

The present invention for achieving the above object, by the following technical solutions: a kind of dry type leakage tester, it is characterized in that: mainly comprise by last, lower table is by four fixing three-dimensional brackets of forming, vertical cylinder, lateral cylinder and airtight leak locator, described airtight leak locator is located at upper table top, the bottom is fixed with several vertical cylinders, the lower table corresponding with vertical cylinder piston is provided with base plate, described base plate interior is established breather line, the air intake opening of breather line is located at a side of base plate, described air intake opening is connected with the exhausr port of airtight leak locator by tracheae, described lateral cylinder is positioned at base plate one side and is fixed on the lower table, and the lateral cylinder piston of described lateral cylinder is provided with seal plug.

The gas outlet of described breather line is located at the base plate middle part.

Beneficial effect: workpiece is fixed by vertical cylinder, the lateral cylinder mode that the through hole shutoff of radiating element is airtight suppresses for large-scale electronic-device radiator inside, and then the barometric information of observing airtight leak locator determines whether heating radiator leaks gas, test result is directly perceived, accurate, efficient, has guaranteed the quality of electronic-device radiator greatly.

Description of drawings

Fig. 1 is a structural representation of the present invention.

Embodiment

Describe the specific embodiment of the present invention in detail below in conjunction with accompanying drawing and preferred embodiment.Mainly comprise upper table 1, lower table 2, vertical cylinder 3, lateral cylinder 4 and airtight leak locator 5, described upper table connects to form the solid type support by four fixed legs 6 and lower table, described airtight leak locator is located at upper table top, airtight leak locator is the airtight leak locator of FL-296 model that Nagano Feitian (Tianjin) instrument and meter company limited produces, it is 1 to the scope of 999Pa that test specification falls in suitable slight pressure, the air intake opening of airtight leak locator is connected with the exhausr port of air compressor by tracheae, the exhausr port of airtight leak locator is connected with air hole on the base plate by tracheae, tracheae is provided with valve, the bottom is fixed with several vertical cylinders, cylinder is vertically arranged, the quantity of cylinder is decided according to the size of workpiece for measurement, if device is bigger, then select 3 to 5 cylinders for use, if device is less, selects 2 and can compress device.Vertically the piston rod 3-1 of cylinder is provided with pad; be used for protecting workpiece not to be scratched the surface; the lower table corresponding with vertical cylinder piston is provided with base plate 7; base plate is shaped as square; if the workpiece bottom does not have O-ring seal; then on backplate surface, paste one deck rubber seal; the shape of O-ring seal is consistent with the shape of workpiece mouth; described base plate interior is established breather line 7-1; the diameter of breather line is less than the height of base plate; the gas outlet 7-11 of described breather line is located at the base plate middle part; make gas can flow into workpiece inside smoothly; the air intake opening 7-12 of breather line is located at a side of base plate, and the air intake opening of this leakage tester is located at the outer side of base plate, to make things convenient for the discharging of tracheae.Described air intake opening is connected with the exhausr port 5-1 of airtight leak locator by tracheae 8.Described lateral cylinder is positioned at base plate one side and is fixed on the lower table, and the quantity of lateral cylinder is decided according to the quantity of the through hole of radiating element side, and this device is five, is neck and neck on the base plate.For the through hole of energy shutoff radiating element side Different Rule, the lateral cylinder piston of described lateral cylinder is provided with seal plug 4-1, and the position assurance of seal plug and the position of radiating element side through hole are on same straight line.Above-mentioned all cylinders all are connected with air compressor by tracheae, by the to-and-fro movement of valve control cylinder piston.

During use, workpiece to be detected is placed on the base plate, guarantee the inside of the gas outlet of breather line at workpiece, open the valve of vertical cylinder, make the downward workpiece pressing of vertical cylinder piston rod, then open the valve of lateral cylinder, make the through hole of the seal plug shutoff of lateral cylinder piston rod in the radiating element side, open airtight leak locator at last, to the pressurization of workpiece internal ventilation, in workpiece, feed the gas of 0.023MPa, duration of ventilation is 104s, observe the reading on the airtight leak locator, if the pressure differential that shows is less than 100Pa, then this workpiece is specification product, if reading is greater than 100Pa, then workpiece has the place of gas leakage, is substandard product.

The above only is a preferred implementation of the present invention; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the principle of the invention; can also make some improvements and modifications, these improvements and modifications also should be considered as protection scope of the present invention.
