All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 7, a valve having a sealing dustproof property and an assembling device thereof includes: a base 1 and a spindle 14; the valve that treats the equipment is last to have end cover 9, threaded connection has first screw rod 7 on the end cover 9, base 1 has the horizontally up end, 14 vertical arrangements of main shaft, main shaft 14 with base 1 rotates to be connected, fixedly connected with frame 2 of the bilateral symmetry of main shaft 14, fixedly connected with anchor clamps 25 on the base 1, anchor clamps 25 are used for the fixed valve of treating the equipment of centre gripping. Vertical through-hole has been seted up on frame 2, sliding connection has lead screw 35 in the through-hole, it is connected with mounting bracket 8 to rotate on the lower terminal surface of frame 2, mounting bracket 8 arranges the mounting hole 4 of end cover 9 directly over. The lead screw 35 runs through mounting bracket 8, and with 8 threaded connection of mounting bracket, fixed mounting has two symmetrical arrangement's first pole 12 on the lateral wall of lead screw 35, the lower extreme fixedly connected with sucking disc 13 of first pole 12, sucking disc 13 is used for adsorbing fixed valve's end cover 9. The mounting frame 8 is arranged right above the mounting hole 4 of the end cover 9. The lower end of the mounting frame 8 is provided with a sealant nozzle which is aligned with the edge of the mounting hole 4. And a driving mechanism is fixedly arranged on the upper end surface of the frame 2 and used for driving the screw rod 35 to move up and down. The bottom surface of the screw rod 35 is provided with a counter bore 20, the first screw rod 7 is matched in the counter bore 20, the side wall of the lower end of the screw rod is provided with a plurality of elastic bulges, a first groove 5 corresponding to the lower end of the first screw rod 7 is arranged in the mounting hole 4, and the bottom of the side wall of the first groove 5 is provided with a clamping groove corresponding to the elastic bulges.

In this embodiment, before assembly, the housing 3 of the valve is clamped and fixed on the clamp 25, the mounting hole 4 is upward, and the main shaft 14 is rotated, so that the screw rod 35 and the mounting frame 8 move to the position right above the mounting hole 4. The operator can screw-fit 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, it is necessary that the screw rod is not self-locked in the screw-thread fit with the mounting bracket 8, that is, the lead angle is larger than the static friction angle, specifically, the design parameters can be calculated by the skilled in the art according to the mechanical principle, and are not described in detail in this embodiment. When the assembly is arranged, the operator can drive the screw rod 35 to slide downwards, so that the first screw rod 7 and the end cover 9 move downwards along with the screw rod 35. Meanwhile, the screw rod 35 drives the mounting frame 8 to rotate in a sliding mode, the mounting frame 8 rotates, meanwhile, the sealant spray head is started to work, sealant is sprayed on the side wall of the mounting hole 4, and therefore the sealing performance between the end cover 9 and the shell 3 of the valve 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 extends into the first groove 5, so that the elastic salient point is extruded, and when the elastic salient point enters the clamping groove and slides into the clamping groove, the elastic salient point is elastically restored, so that the elastic salient point is clamped in the clamping groove. Thus, the lower end of the screw can be synchronously clamped with the clamping groove while the end cover 9 is pressed into the mounting hole 4. The first groove 5 may be disposed on the valve housing 3, and for the structure disclosed in the background art, the first groove 5 may be disposed on the semicircular clip piece 31.

The location of the end of the sealant spray head needs to avoid interference with the depressed end cap 9. Specifically, the end of the sealant sprayer and the inner edge of the mounting hole 4 have a gap. Of course, the above gap does not make it difficult for the sealant to reach the inner wall of the mounting hole 4, and can be avoided by increasing the spraying distance appropriately. For example, the specific structure of the elastic bump may include a base plate 33, a rotating plate 32 and a spring 34, the base plate 33 is attached to the sidewall of the screw 35, and one end of the rotating plate 32 is hinged to the lower end of the base plate. One end of the spring 34 is connected with the upper end of the rotor 32, and the other end of the spring 34 is fixedly connected with the substrate.

One side of the upper end surface of the base 1, which is far away from the clamp 25, is fixedly connected with a first lifting table 17, the first lifting table 17 is used for driving the first screw 7 to be assembled to move up and down, and the end cover 9 to be assembled is matched with the first screw 7 to be assembled.

The bottom surface of the counter bore 20 is provided with a magnet, and the first screw 7 is made of iron. In this embodiment, a mechanism is provided for delivering the end cap 9 with the first screw 7. Specifically, the first screw 7 may be screwed into the end cap 9 in advance. And driving a lifting platform 17 on the base 1, and lifting the bottom surface of the end cover 9 by the lifting platform 17, 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 platform 17 provides a jacking force to extrude the air in the sucker 13, the sucker 13 is in a vacuum state without pressure, and the pressure difference formed between the sucker 13 and the outside is certainly pressed by the outside pressure, so that the end cover 9 is adsorbed and fixed. Meanwhile, the end cover 9 is in threaded fit with the first screw 7, and the first screw 7 is synchronously lifted along with the end cover 9 and cannot fall off. 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. It should be noted that the suction cup 13 is used to fix the end cap 9 during transferring, and is not always fixed to the end cap 9 by suction. When the sealant of the end cap 9 is effective or the end cap 9 is fixed to the valve housing 3 by fastening bolts, the suction cup 13 can be separated from the upper end surface of the end cap 9 by pulling up the screw 35. The total suction force of the suction cup 13 is greater than the total weight of the assembly of the end cap 9 and the first screw 7, and less than the fastening force between the end cap 9 and the valve housing 3 after the assembly.

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 screw and the end cover 9. A support 16 is arranged between the first lifting platform 17 and the main shaft 14, a charging barrel 33 is fixedly mounted at the upper end of the support 16, a discharge hole is formed in the bottom surface of the charging barrel 33, a second screw 15 which is vertically arranged is arranged in the charging barrel 33, the second screw 15 penetrates through the discharge hole, and a gap for discharging is formed between the discharge hole and the second screw 15.

The lower end of the second screw 15 is rotatably connected with the upper end face of the support 16, a roller 18 is fixedly sleeved on the second screw 15, and the roller 18 is attached to the outer wall of the end cover 9 to be assembled. The roller 18 is positioned below the charging barrel 33, a connecting frame 26 is arranged between the charging barrel 33 and the roller 18, a bearing plate 27 is arranged between the connecting frame 26 and the charging barrel 33, a gap is arranged on the bearing plate 27, a ramp 19 is arranged on the connecting frame 26, and the middle part of the ramp 19 is rotatably connected with the connecting frame 26. The upper end of the ramp 19 is aligned with the gap and the lower end of the ramp 19 extends above the second groove 6.

Before the assembly of the end cover 9 and the first screw 7 is moved to the screw rod 35 and the mounting frame 8, the second screw 15 can be rotated to spirally press down the second screw 15, so as to extrude the filler material in the material barrel 33, so that the filler material is extruded from the discharge hole and falls onto the bearing plate 27, and then falls into the ramp 19 through the gap of the bearing plate 27 and is further conveyed to the second groove 6, thereby completing the supply of the sealing filler. The second screw 15 can also drive the roller 18 to rotate while rotating, the outer wall of the roller 18 is attached to the outer wall of the non-jacked end cover 9, and the two are in interference fit. The end cover 9 can be driven to synchronously rotate by the rotating friction force of the roller 18, so that the end cover 9 can synchronously rotate while the lower second screw 15 presses the filler, the filler falling from the ramp 19 can be uniformly sprinkled in the second groove 6, and the gland only needs to be pressed and assembled on the second groove 6 subsequently. In the attached drawings of the application, because the end cover is far away from the second screw rod, two rollers are arranged side by side for transmission. In fact, the number of the rollers can be adjusted according to requirements, and it cannot be understood that two rollers are required to be used in the practical scheme of the application. It should also be noted that the ramp 19 is hinged to the connecting frame 26. Thus, in the operating state, the ramp 19 extends over the second groove 6 for transport. After the filling material is supplied, when the end cover 9 is lifted, the end cover 9 can jack the ramp 19, so that the ramp 19 rotates, and the interference of the ramp 19 on the upward movement of the end cover 9 close to the screw rod 35 is avoided.

The upper end of the second screw 15 is fixedly sleeved with a second belt wheel 29, the upper end of the main shaft 14 is fixedly sleeved with a first belt wheel 28, and the second belt wheel 29 is in transmission connection with the first belt wheel 28 through a transmission belt 30. During assembly, the base 1 has a station for assembly on one side with the clamp 25, while the other side (having the side made) is used for delivery of the assembly. The main shaft 14 drives the frame 2 to switch between the two stations. Simultaneously with the rotation of the main shaft 14, the main shaft 14 drives the first belt pulley 28 to rotate, and then drives the second belt pulley 29 to rotate through the transmission belt 30, so as to drive the second screw 15 to rotate, and thus complete the delivery of the sealing filler.
