The machine frame 2 is provided with a vertical through hole, a screw rod 35 is slidably connected in the through hole, a mounting frame 8 is rotatably connected to the lower end face of the machine frame 2, and the mounting frame 8 is arranged right above the mounting hole 4 of the end cover 9. The lead screw 35 runs through the mounting frame 8 and is in threaded connection with the mounting frame 8, two symmetrically arranged first rods 12 are fixedly arranged on the side wall of the lead screw 35, the lower end of each first rod 12 is fixedly connected with a sucker 13, and the suckers 13 are used for adsorbing an end cover 9 of a fixed valve. The mounting frame 8 is arranged right above the mounting hole 4 of the end cover 9. The lower extreme of mounting bracket 8 is equipped with the sealant shower nozzle, the sealant shower nozzle with the edge alignment of mounting hole 4. A driving mechanism is fixedly arranged on the upper end surface of the frame 2 and is used for driving the screw rod 35 to move up and down.

The operator can screw the first screw 7 with the end cap 9 in advance, and the suction cup 13 is sucked on the upper end face of the end cap 9. For the screw rod 35, in the design process, the screw fit with the mounting frame 8 is required to have no condition of no self-locking, that is, the lead angle of the screw is larger than the static friction angle, and specifically, the design parameters can be calculated by a person skilled in the art through a mechanical principle, and the details are not repeated in the embodiment. When the assembly arrangement is completed, the operator can drive the screw 35 to slide downwards so that the first screw 7 and the end cap 9 move downwards with the screw 35. Meanwhile, the lead screw 35 slides to drive the mounting frame 8 to rotate, and the sealing glue spray head is started to work while the mounting frame 8 rotates, so that sealing glue is sprayed on the side wall of the mounting hole 4, and the tightness between the end cover 9 and the valve shell 3 is further improved. The screw 35 continues to move downwardly until the end cap 9 engages the mounting hole 4. Meanwhile, the lower end of the screw rod gradually penetrates into the first groove 5, so that the elastic protruding point is extruded, and when the elastic protruding point enters the clamping groove and slides into the clamping groove, the elastic protruding point is elastically restored, so that the elastic protruding point is clamped in the clamping groove. Thus, the screw rod can be synchronously clamped with the clamping groove at the lower end of the screw rod when the end cover 9 is pressed into the mounting hole 4. For the first recess 5, a valve housing 3 can be arranged, and for the constructions disclosed in the background art, the first recess 5 can be provided on the semicircular catch 31.

The position of the end of the sealant head needs to be protected from interference with the depressed end cap 9. Specifically, the end of the sealant nozzle and the inner edge of the mounting hole 4 have a gap. Of course, the gap does not cause the sealant to hardly reach the inner wall of the mounting hole 4, and the distance of the injection is appropriately increased to avoid the sealant. For example, for the specific structure of the elastic bump, the elastic bump may include a base plate 33, a rotating plate 32 and a spring 34, where the base plate 33 is attached to a side wall of the screw rod 35, and one end of the rotating plate 32 is hinged to the lower end of the base plate.

In this embodiment, a mechanism is provided to deliver the end cap 9 with the first screw 7. Specifically, the first screw 7 may be screwed onto the end cap 9 in advance. The lifting table 17 is driven on the base 1, and the lifting table 17 lifts the bottom surface of the end cover 9, so that the end cover 9 moves upwards to attach the upper end surface of the end cover 9 to the sucker 13. The lifting table 17 provides a lifting force to extrude air in the sucker 13, the sucker 13 is in a vacuum state and has no pressure, and the air can be naturally pressed by the pressure of the outside due to the pressure difference with the outside, so that the adsorption and fixation of the end cover 9 are completed. Meanwhile, since the end cover 9 is screwed with the first screw 7, the first screw 7 is lifted up in synchronization with the end cover 9 without falling down. When the main shaft 14 rotates to drive the frame 2 to move, the first screw 7 can also move along with the end cover 9. Here, the suction cup 13 is used to fix the end cap 9 during transfer, and is not always fixed to the end cap 9 by suction. Pulling up the lead screw 35 can disengage the suction cup 13 from the upper end surface of the end cap 9 when the sealant of the end cap 9 is effective, or when the end cap 9 is fixed to the valve housing 3 by fastening bolts. The suction force of the suction disc 13 is larger than the total weight of the assembly formed by the end cover 9 and the first screw rod 7, and smaller than the fastening force between the end cover 9 and the valve housing 3 after the assembly is completed.

The upper end face of the end cover 9 is provided with a second groove 6 for containing sealing filler, and the filler extends to the joint of the first screw 7 and the end cover 9.

The second screw 15 rotates and simultaneously drives the roller 18 to rotate, and the outer wall of the roller 18 is attached to the outer wall of the non-lifted end cover 9 and is in interference fit with the outer wall of the non-lifted end cover. The friction force of the rotation of the roller 18 can drive the end cover 9 to synchronously rotate, so that the end cover 9 can synchronously rotate while the lower second screw 15 presses down the filler, the filler falling from the ramp 19 can be uniformly sprinkled in the second groove 6, and the gland is only pressed and assembled on the second groove 6 in the follow-up process. In the drawing, the end cover is far away from the second screw rod, so that two rollers are arranged side by side for transmission. In fact, the number of rollers can be adjusted according to the requirement, and it cannot be understood that two rollers are necessary for the practical solution of the present application. It should be further noted that ramp 19 is hinged to connecting frame 26. Thus, in the operating state, ramp 19 extends over second recess 6 for transport. When the supply of filler is completed, end cap 9 can lift ramp 19 when end cap 9 is lifted, causing ramp 19 to rotate, thereby avoiding ramp 19 from interfering with the upward movement of end cap 9 adjacent screw 35.
