DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-Figure 5The utility model provides a technical solution: an automated gas self-closing valve bracket production device, including a base 1, a storage rack 2, a support frame 3, an electric telescopic rod 4, a grinding device 5, a fixing plate 6, a servo motor 7, a different-direction threaded rod 8, a threaded connector 9, a clamping plate 10, a limit rod 11, a sliding block 12, a water tank 13, a water outlet pipe 14, an atomizing nozzle 15, a latch 16, a gear 17, a traction rope 18, a telescopic spring 19 and a sealing plate 20.

[0024] A storage rack 2 is fixedly installed on the upper end of the base 1, and a support frame 3 is fixedly installed on the upper end of the base 1, an electric telescopic rod 4 is fixedly installed on the inner side of the support frame 3, and a grinding device 5 is fixedly installed on the output end of the electric telescopic rod 4, a fixing plate 6 is fixedly installed on the upper end of the base 1, and a servo motor 7 is fixedly installed on the outer side of the fixing plate 6, a different direction threaded rod 8 is fixedly installed on the output end of the servo motor 7, and a threaded connector 9 is connected to the outer side of the different direction threaded rod 8, and a splint 10 is fixedly installed on the outer side of the threaded connector 9, a limiting rod 11 passes through the inner side of the fixing plate 6, and a sliding block 12 is nested on the outer side of the limiting rod 11, and the sliding block 12 is fixedly installed on the outer side of the splint 10.

[0025] according to Figure 1-Figure 3 As shown, the threaded connector 9 is threadedly connected with the different-direction threaded rod 8 through the threaded hole opened on the inner side, and the different-direction threaded rod 8 and the fixed plate 6 form a rotating structure; the sliding block 12 and the limiting rod 11 form a sliding structure, and the limiting rod 11 and the different-direction threaded rod 8 are distributed in a front-to-back correspondence with respect to the midpoint of the clamping plate 10;

[0026] When it is necessary to grind the outer surface of the self-closing valve bracket of this structure, the self-closing valve bracket is first placed on the upper end of the storage rack 2, and then the servo motor 7 is operated. The output end of the servo motor 7 drives the counter-rotating threaded rod 8 to rotate, so that the two groups of threaded connectors 9 on the outer sides of the counter-rotating threaded rod 8 move toward each other (the outer sliding block 12 slides along the outer side of the limiting rod 11 to limit the angle of the threaded connector 9). As the distance between the two groups of threaded connectors 9 continues to get closer, the arc-shaped clamping plate 10 at the upper end will fit against the outer side of the self-closing valve bracket to clamp and limit the self-closing valve bracket to prevent the self-closing valve bracket from being displaced during grinding.

[0027] A water tank 13 is fixedly installed on the inner side of the support frame 3, and a water outlet pipe 14 is fixedly connected to the outer side of the water tank 13, and an atomizing nozzle 15 is fixedly connected to the tail end of the water outlet pipe 14, a latch 16 is fixedly installed on the outer side of the grinding device 5, and a gear 17 is connected to the outer side of the latch 16, the gear 17 is installed on the inner side of the support frame 3, and a traction rope 18 is wound around the central axis of the gear 17, and a sealing plate 20 is fixedly connected to the tail end of the traction rope 18, a telescopic spring 19 is fixedly installed on the inner side of the water outlet pipe 14, and a sealing plate 20 is fixedly connected to the tail end of the telescopic spring 19, and the sealing plate 20 is nested inside the water outlet pipe 14;

[0028] according to Figure 1 , Figure 4-Figure 5 As shown, the gear 17 and the support frame 3 form a rotating structure, and the gear 17 and the latch 16 are meshingly connected; the central axis of the gear 17 forms a traction structure with the sealing plate 20 through the traction rope 18, and the sealing plate 20 forms an elastic structure with the water outlet pipe 14 through the telescopic spring 19;

[0029] This structure drives the grinding device 5 to move downward through the output end of the electric telescopic rod 4 to grind the fixed self-closing valve bracket. When the grinding device 5 moves downward, the outer clamping teeth 16 drive the gear 17 to rotate, so that the central axis inside the gear 17 reels the traction rope 18, so that the traction rope 18 generates traction force on the sealing plate 20, squeezes the telescopic spring 19 to slide along the inside of the water outlet pipe 14, and the sealing plate 20 slides to open the water outlet pipe 14. The water inside the water tank 13 will be sprayed out from the inside of the atomizing nozzle 15 through the operation of the water pump to reduce the dust generated by grinding.
