After such setting, only a group of air pumps 61 and air charging nozzles 62 are required to be arranged, the air receiving nozzles 72 are arranged on each detection base 2, and the air receiving nozzles 72 are enabled to point to the air charging nozzles 62 along the rotation direction of the detection base 2, so that when the detection base 2 rotates towards the first gland mechanism, namely moves towards the position of the air charging nozzles 62, the air charging nozzles 62 are firstly nested with the inclined outward expanding nozzles 73, and along with the continuous movement of the detection base 2, the air charging nozzles 62 are completely embedded into the outward expanding nozzles 73, the gasket 712 seals the joint of the two, and the second reset piece 76 is bent and compressed to deform. At this time, under the pushing action of the air charging nozzle 62, the expanding nozzle 73 drives the air receiving nozzle 72 to move upwards in the ball seat 71, the first reset piece 75 is stretched to deform, and the air hole 74 on the air receiving nozzle 72 is communicated with the closed cavity in the detection base 2, so that after the air pump 61 is controlled to be started, air can be supplied to the shaft hole of the side gear 91 added with the sealing cover 92.
After the air supply is completed, the lower disc 12 drives the detection base 2 to continue to rotate, the outer expansion nozzle 73 moves to the other side of the air charging nozzle 62 and gradually inclines, at this time, the air receiving nozzle 72 moves downwards under the action of the elastic deformation force of the first reset piece 75, the air hole 74 on the air receiving nozzle 72 is retracted into the ball seat 71, and a pressure maintaining state is formed in the detection base 2, so that airtight detection can be performed. When the expanding nozzle 73 is completely separated from the charging nozzle 62, the expanding nozzle 73 is not pushed by external force, and the receiving nozzle 72 is turned over and reset to the initial inclined state under the action of the elastic deformation force of the second reset piece 76 so as to meet the next butt joint with the charging nozzle 62. In this way, the single air charging nozzle 62 can realize the alternate automatic butt joint and air charging of the plurality of air receiving nozzles 72, greatly simplifies the structural arrangement of the air charging mechanism, and is easier to maintain.
Meanwhile, referring to fig. 1, the aforementioned feeding mechanism includes a rotary lifting cylinder 81 mounted on the workbench 11, the rotary lifting cylinder 81 can lift and rotate at a fixed angle a piston rod thereof, a material moving plate 82 is fixedly connected to an output end of the rotary lifting cylinder 81, a material moving member 83 for adsorbing a sealing cover 92 is mounted at one end of the material moving plate 82 far from the rotary lifting cylinder 81, and the material moving member 83 is a vacuum chuck.
In this way, when the feeding mechanism works, the rotary lifting cylinder 81 is used for driving the material moving plate 82 to rotate to an initial position, the material moving part 83 is positioned above the material rack 31 at the initial position, the precursor is used for driving the material moving part 83 to move downwards and adsorbing the cover 92 at the uppermost part of the material rack 31, then the material moving part 83 is lifted upwards, the rotary lifting cylinder 81 is used for driving the material moving plate 82 to rotate to the position above the detection base 2 corresponding to the first gland mechanism and move downwards, and the material moving part 83 is used for removing the adsorption of the cover 92, so that accurate feeding can be performed on the detection base 2; in this process, the linear driving member in the workbench 11 moves up to the bottom plate 32 in the material rack 31 by a distance equal to the thickness of the cover 92, so that the uppermost cover 92 can be lifted to the feeding position, and the material moving member 83 can directly suck and feed materials.
The implementation principle of the self-sealing differential side gear gland and the airtight detection device is as follows: when the gland and the air tightness of the half shaft gear 91 are detected and assembled, the feeding mechanism feeds the sealing cover 92 onto the half shaft gear 91 of the detection base 2 below the first-position gland mechanism, the gland member 5 is arranged on the taking and placing mechanism, and the gland member 5 can be pressed down to finish the gland operation; and then the taking and placing mechanism drives the gland member 5 to rotate and be clamped on the detection base 2, the detection base 2 is inflated through the inflation mechanism, the gland member 5 clamped on the detection base 2 can compress the side gear 91 to realize pressure maintaining, and then the leak detector detects the pressure difference and the air tightness of the side gear 91 after being pressed. Therefore, the semi-automatic capping operation and the airtightness detection operation of the single side gear 91 can be realized through the application, the integration level is higher, and the processing is more efficient.
After the two gland mechanisms are symmetrically arranged, the second gland mechanism which absorbs the gland members 5 moves to the first gland mechanism, so that the new detection base 2 can be subjected to gland operation, and the first gland mechanism moves to the second gland mechanism to absorb the gland members 5 on the new detection base 2; the two gland mechanisms can carry out assembly line gland operation and gland piece 5 sucking operation on the side gears 91 on the detection bases 2 in a circulating and reciprocating mode, the operation efficiency is higher, the setting quantity of the gland pieces 5 is also saved, and the gland operation and the air tightness detection operation are realized more conveniently and efficiently.
