Abstract
The utility model discloses a hermetic testing device of rubber parts, which consists of a test bed, trough and air compression pump; the test bed is equipped in the trough and the air compression pump is connected with the pipeline of the test bed shelf; the described test bed shelf consists of a base, supporting rod, movable plate, fixed ring, straight-through pipe and rectangular through pipe; the supporting rod is connected and supported with the base, in the middle of which is equipped with the fixed ring for fixing the big end of the rubber part, the supporting rod is connected with the movable plate through nuts, the movable plate is equipped the straight-through pipe, and the gas pipe of the air compressing pump is connected with one end of the straight-through pipe, whose other end is connected with the small end of the rubber parts. The tester can provide a constant and suitable gas pressure and water sealed environment for rubber parts, determining the quality of the airtight rubber parts and the defect locations with micro-defect rubber parts in an objective manner, it has the advantages of compact design structure, easy operation and direct observation of results.
Description
Technical field
The utility model belongs to rubber component test, detection technique field, is specifically related to the test unit that a kind of rubber part carries out air-tight test, is particularly useful for motor turning rod assembly rubber part is tested.
Technical background
Rubber parts such as gear side dust cover, tooth bar side dust cover are the important components of motor turning rod assembly, be assemblied in gear one side and tooth bar one side of steering linkage, major function is to be used to protect steering linkage assembly kinematic train to resist road sandstone bump, muddy water spray and atmospheric environment corrosion, guarantees motor turning flexible function safety.
Be subjected to the restriction of the current elastomeric material and the part processing state of the art, the rubber part microdefect quality problems of motor turning rod assembly are comparatively outstanding, have a strong impact on the functions of use of the rubber part of motor turning rod assembly.Therefore, the rubber part microdefect that accurately detects the motor turning rod assembly is one of important measures of ensureing of the quality of rubber part.
The rubber part microdefect of motor turning rod assembly adopts the listening method to carry out qualitative detection mostly at present, and this method subjectivity is strong, can not accurately detect the position of microdefect and microdefect thereof.
Air-tight test is an emerging detection technique, and ultimate principle is under the test condition of quantitative pressurization and water-stop, by measuring the position of the variation of parts pressure, bubble and generation bubble, detects the impermeability at parts break-in position.This technology obtains to use in the metallic element driving fit performance detection, and for example: automobile and motorcycle valve parts air-tightness detect.But the air-tight test technology is not as yet at rubber part, and especially the microdefect of automobile rubber part is applied in detecting, and for the bubble-tight quality of objective judgement rubber part, also do not have the tightness test device of a sleeve forming at present.
Summary of the invention
The purpose of this utility model is at existing testing equipment above shortcomings, designs the test unit that a kind of rubber part impermeability detects, to reach the purpose of the microdefect that detects rubber part qualitatively.
The technical solution of the utility model is as follows:
The rubber part tightness test device is made up of test-bed, tank and air pressure pump three parts, and test-bed places tank, and air pressure pump connects the pipeline on the test-bed.Test-bed is made up of base, support bar, portable plate, retainer plate, straight pipe and right angle siphunculus, the support bar connection is supported on the base, be connected with portable plate by nut on the support bar, retainer plate is installed in the middle of the base, the big end that is used for fixing rubber parts, straight pipe is installed on the portable plate, and the gas circuit of air pressure pump connects of straight pipe, and the other end of straight pipe is used to connect the small end of rubber parts.
In addition, the right angle siphunculus is installed also on portable plate, passes through a three-way pipe on the gas circuit of air pressure pump, the air-flow of air pressure pump is divided into two-way, one the tunnel is connected in of straight pipe, and another road is connected in of right angle siphunculus, and siphunculus other end, right angle connects tensimeter.
Testing process:
(1) the clamping rubber part is installed: on the retainer plate of stand, the small end clamping of rubber part is used the dead ring clamping respectively on straight pipe, adjust the portable plate height and make rubber part in the raw with the big end clamping of rubber part.
(2) connect gas circuit: by three-way pipe the air-flow of air pressure pump is divided into two-way, the one tunnel is connected on the straight pipe, and another road is connected on the right angle siphunculus.
(3) detect: whole stand is placed in the tank, and the water surface and portable plate upper horizontal plane maintain an equal level best.Pump speed is set, makes pump provide suitable a, constant compression force to rubber part.Show that then rubber part has microdefect if parts have pressure to change, produce bubble, impermeability is bad; Otherwise show that then the rubber part impermeability is good.
This test unit can provide constant, suitable air pressure of rubber part and water-stop environment, position by gaging pressure variation, bubble and generation bubble, can confirm simultaneously that rubber part has or not the position of microdefect (pore, crackle) and microdefect, the bubble-tight quality of objective judgement rubber part and the defective locations of microdefect rubber part is arranged has that the structural design compactness is succinct, easy to operate, the result observes direct advantage.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
Referring to Fig. 1, this tightness test device is made up of test-bed 1, tank 2 and air pressure pump 3 three parts.Wherein the base 11 of test-bed has been the support fixation effect, and base 11 is connected and fixed with support bar 14 usefulness hold-down nuts 12.In the middle of the base 11 retainer plate 13 is arranged, be used for fixing the big end of rubber part.Support bar 14 its supporting roles, the first half is threaded, connects portable plate 15 by nut, portable plate 15 can arbitrarily adjust by nut and base between height.Straight pipe 16 and right angle siphunculus 17 are installed on the portable plate 15, air pressure pump 3 is divided into two-way by a three-way pipe with air-flow, one the tunnel is connected in the A mouth of straight pipe 16, another road is connected in the C mouth of right angle siphunculus 17, the B mouth of straight pipe 16 is rubber part fixedly, the D mouth of right angle siphunculus 17 connects air manometer, in time monitors the pressure condition of rubber part in process of the test.Tank 2 is the uncovered clear glass grooves of rectangular parallelepiped, and good rubber part immerses in the water fully to make clamping.
