Description

Technical Field

[0001] The present invention relates to the technical field of airtightness detection equipment, and in particular to an automatic airtightness detection equipment for pipe fittings. Background Art

[0002] The accurate detection of micro-leakage of pipe fittings by automated airtightness is a difficult task. Currently, it is mainly done manually, in which the pipe fittings are ventilated inside and sunk into water to observe whether bubbles appear around the pipe fittings over a period of time. However, it is easy to misjudge due to fatigue of personnel after long-term high-intensity work. Long-term contact with water (especially cold water) may easily lead to occupational diseases of employees. Most people are reluctant to do this job, so the automated airtightness detection equipment for pipe fittings came into being. It can automatically load the product, clamp and inflate in an orderly manner, transfer the workstation in a cycle, collect and detect the leaked gas at the detection station, accurately judge the large, small and micro leakage of the product pipe fittings, and finally dispose of good and inferior products separately. It can accurately identify the leakage of pipe fittings and sort them, improve the automation capability, and one person with more than one machine can improve production efficiency and reduce various costs.

[0003] When inspecting pipe fittings, the fixture brings the pipe fittings into the water tank for inspection through the rotation of the turntable. However, there are often a large number of impurities such as metal debris and sand and gravel in industrial water, and the pipe fittings are directly put into the water during inspection without any filtering measures. This means that when the pipe fittings are inspected in water, if impurities are stuck on the pipe fittings, even if the pipe fittings are unqualified, the test results will be abnormal due to the influence of impurities, which affects the inspection accuracy of the pipe fittings. When the pipe fittings are inspected in water, due to the buoyancy of the water or the failure of the fixture, the pipe fittings fall off, which will cause the pipe fittings to sink directly into the water. Due to the deep water level, it is not easy to salvage, and it is automated production, so it is not easy for workers to detect, which leads to the problem of pipe fittings being damaged due to long-term immersion.

At the same time, the installation shaft 710 rotates in the rotating groove 717 and drives the torsion spring 718 to be stressed. At the same time, the rotation of one bevel gear 711 drives another bevel gear 711 Rotate, so that the bevel gear 711 drives a synchronous gear 708 to rotate, and the rotation of one synchronous gear 708 drives the other synchronous gear 708 to rotate, so as to realize the synchronous rotation of the two synchronous gears 708, and the rotation of the two synchronous gears 708 drives the two synchronous rotating rods 705 to rotate, and the synchronous rotating rod 705 drives the push-pull rod 702 to move through the push-pull shaft 706, and the movement of the push-pull rod 702 drives the filter plate 701 to move, so that the two filter plates 701 can be automatically closed when entering the water tank, which can ensure that the impurities in the water tank 3 enter the fixture 5, affecting the detection of the pipe fitting 10 or damaging the fixture 5, and does not affect the water entering the installation box 6; Furthermore, when the installation box 6 enters the water tank 3, the friction wheel 805 is squeezed by the inner wall of the water tank 3, so that the friction wheel 805 rotates while moving in the water tank 3, and the rotation of the friction wheel 805 drives the connecting shaft 804 to rotate, and the connecting shaft 804 drives the driving column 806 to rotate. When the driving column 806 rotates, it drives the driving shaft 810 to rotate through the inclined driving groove 809, so that the driving shaft 810 moves, and the driving shaft 810 slides in the transverse sliding groove 807 through the transverse moving block 808, and when the driving column 806 rotates one circle, the driving shaft 810 reciprocates once, so that the transverse moving block 808 drives the cleaning rack 801 to reciprocate, and the cleaning rack 801 cleans the filter plate 701 through the cleaning brush 803 to prevent impurities from clogging the filter plate 701, resulting in insufficient water in the installation box 6; Furthermore, if the installation box 6 moves to the position where the opening faces downward during the rotation of the turntable 4, if the pipe 10 falls due to the failure of the clamp 5 or the pipe 10 is not clamped, the pipe 10 no longer squeezes the extrusion frame 903. At this time, under the return force of the reset spring 904, the extrusion frame 903 is pulled to move, and the extrusion frame 903 drives the locking rack frame 901 to move, so that the locking rack frame 901 locks the two synchronous gears 708, thereby locking the positions of the two filter plates 701 and closing the installation box 6, effectively avoiding the problem of the pipe 10 falling into the water tank 3.
