[0021] The machine also includes a turntable 4 on which a rotating arm 41 is rotatably mounted. The rotating arm 41 is provided with three grabbing units 42 distributed in a circle around the center of the turntable 4. The grabbing units 42 grab the sealing gasket, the inspection port cover and the press-fitted finished product respectively.

[0022] The press-fitting assembly 3 includes a pressing plate 31, and a pressing portion 32 that conforms to the sealing gasket is provided on the circumference of the pressing plate 31. The pressing plate 31 is equipped with a No. 1 cylinder 33 fixed on the workbench 1; after the grabbing unit 42 assembles the sealing gasket and the inspection port cover, the No. 1 cylinder 33 drives the pressing plate 31 to press down, so that the colloid on the sealing gasket cooperates with the inspection port cover.

[0023] The positioning assembly 23 is slidably mounted in the support platform 21 to adapt to two groups of positioning pins 231 of different types of inspection port covers. The positioning pins 231 are all equipped with springs 232 that abut against the support platform 21. Each group of positioning pins 231 is connected to a mounting plate 233. The mounting plate 233 is connected to a lead-out portion 234 extending from the bottom of the support platform 21. The bottom of the support platform 21 is provided with a driving unit 24 that cooperates with the lead-out portion 234 to drive the corresponding positioning pin 231 to rise and fall; the driving unit 24 is provided with two in the horizontal direction to ensure that the positions of the two sides of the mounting plate 233 are the same, to prevent the positioning pin 231 from being inconsistent in height due to failure of the spring 232; the support platform 21 includes an upper layer and a lower layer, and the positioning pin 231 is slidably mounted on the upper layer. At the same time, the spring 232 abuts against the upper layer to drive the positioning pin 231 to return to its original position, and the lead-out portion 234 slidably cooperates with the lower layer to assist the mounting plate 233 in lifting and driving the positioning pin 231 to cooperate with the sealing gasket and the inspection port cover.

[0024] The drive unit 24 includes a handle 241 rotatably mounted on the support platform 21. The handle 241 is connected to a cam 242. The lead-out portion 234 is provided with an arc block 243 that cooperates with the cam 242. The handle 241 can slide in a circumferential direction so that the cam 242 and the corresponding arc block 243 respectively drive the two sets of positioning pins 231 to rise and fall to meet the needs of assembling different types of inspection cover. Rotating the handle 241 90 degrees causes the cam 242 to lift the arc block 243 to its highest height, allowing the positioning pins 231 to cooperate with the sealing gasket and inspection cover for positioning.

[0025] The support assembly 2 also includes a support frame 25 for supporting the inspection port cover, and a No. 2 cylinder 26 is provided on the workbench 1 to drive the support frame 25 to rise and lower to lift the inspection port cover; after the pressing is completed, the No. 2 cylinder 26 drives the support frame 25 to rise and lift the inspection port cover to facilitate the grasping unit 42 to grasp the finished product; the support frame 25 is provided with three groups of support blocks in the horizontal direction, and each group of support blocks is symmetrically distributed along the width direction of the support frame 25.

[0026] The grabbing units 42 all include a No. 3 cylinder 421 installed on the rotating arm 41, and the No. 3 cylinders 421 are connected to a grabbing platform 422. The grabbing platform 422 is provided with suction units 43 symmetrically distributed along the length direction of the grabbing platform 422, and the grabbing platform 422 is also provided with clamping units 44 symmetrically distributed along the width direction of the grabbing platform 422 for clamping the sucked parts; the No. 3 cylinder 421 drives the grabbing platform 422 to rise and fall, so that the suction unit 43 and the clamping unit 44 can grab or release the sealing gasket or the inspection cover.

[0027] The suction units 43 all include guide columns 431 symmetrically distributed along the width direction of the grasping platform 422 for inserting parts for positioning, and suction cups 432 for sucking parts are distributed between the guide columns 431. The guide columns 431 and the suction cups 432 are fixed by screws, and the positions can be quickly adjusted to adapt to different types of inspection covers. The sealing gasket and the inspection cover are positioned by the guide columns 431, and the bottom of the guide column 431 can be engaged with the corresponding positioning pin 231, which plays a guiding role during blanking to prevent deviation during blanking and failure of press-fitting; the sealing gasket or inspection cover is sucked and lifted by the suction cup 432, and then clamped by the clamping claw 441 to prevent it from falling off during the rotation of the rotating arm 41.

[0028] The clamping unit 44 includes two sets of clamping jaws 441 hingedly mounted on the grabbing platform 422 and symmetrically distributed along the width direction of the grabbing platform 422. The grabbing platform 422 is provided with a power unit 45 that drives the clamping jaws 441 to rotate to clamp the parts sucked by the suction unit 43. Figure 5 As shown, each group of clamping jaws 441 preferably has three.

[0029] The power unit 45 includes two No. 4 cylinders 451 hingedly mounted on the grabbing platform 422 and symmetrically distributed along the length direction of the grabbing platform 422. The No. 4 cylinder 451 is connected to a driving frame 452 distributed below the grabbing platform 422. A driving rod 453 is hingedly mounted on the driving frame 452. The end of the driving rod 453 away from the driving frame 452 is hingedly connected to the corresponding clamping claw 441; after the suction cup 432 sucks the sealing gasket or the inspection port cover, the No. 4 cylinder 451 drives the driving frame 452 to descend, so that the driving rod 453 drives the clamping claw 441 to rotate around the hinge point to clamp the sealing gasket or the inspection port cover.

[0030] Each of the clamping jaws 441 is provided with a V-shaped clamping block 442 .

[0031] In the present invention, when the sealing gasket and the inspection cover need to be assembled, the first step is to rotate the handle 241 90 degrees so that the cam 242 lifts the arc block 243 to the highest height, so that the positioning pin 231 extends out of the support platform 21;

[0032] Step 2: The No. 3 cylinder 421 drives the grabbing platform 422 to descend, and grabs the access cover through the suction cup 432 and the clamping claw 441. The rotating arm 41 rotates, driving the corresponding grabbing platform 422 to move to the support platform 21;

[0033] Step 3: Release the access cover so that it fits with the positioning pin 231, while the suction cup 432 and the clamping claw 441 of the second station grab the sealing gasket;

[0034] Step 4: The rotating arm 41 rotates, driving the corresponding grabbing platform 422 to move to the support platform 21, releasing the sealing gasket so that the sealing gasket is engaged with the positioning pin 231;

[0035] Step 5: The rotating arm 41 rotates, driving the corresponding grabbing platform 422 away from the support platform 21, and the No. 1 cylinder 33 drives the pressing plate 31 to press down, so that the colloid on the sealing gasket fits with the inspection cover;

[0036] Step 6: After the press-fitting is completed, the No. 2 cylinder 26 drives the support frame 25 to rise, lifts the inspection cover, and the rotating arm 41 rotates, driving the suction cup 432 and the clamping claw 441 of the third station to grab the finished product. At the same time, the suction cup 432 and the clamping claw 441 of the first station grab the inspection cover, and the cycle operation is carried out.
