Description

Technical Field

[0001] The utility model belongs to the technical field of gas meter accessory assembly, in particular to a gas meter vertical shaft sleeve and sealing sleeve grabbing mechanism. Background Art

[0002] With economic development and the accelerating pace of urbanization, the use of natural gas or coal gas is becoming increasingly widespread. In these applications, gas meters are inevitably used to calculate consumption. The vertical shaft sleeve and sealing sleeve in gas meters are essential components.

[0003] The vertical shaft sleeve and sealing sleeve in the gas meter are assembled manually, which is time-consuming and labor-intensive. Not only is the assembly efficiency low, but it is also difficult to ensure the assembly quality. The process is complicated, the cycle is long, and the cost is high. Utility Model Content

[0004] The present invention aims to solve the problems in the prior art and proposes the following technical solutions:

[0005] The gas meter vertical shaft sleeve and sealing sleeve grabbing mechanism includes a three-axis slide and a transmission part. The three-axis slide is equipped with a slide. The slide is fixedly connected to a first fixed seat, a second fixed seat and a third fixed seat on the side away from the three-axis slide. The second fixed seat is located below the first fixed seat. The inner ring fixed sleeve of the first fixed seat is provided with a cylinder. The output end of the cylinder is connected to a grabbing shaft through a coupling. The grabbing shaft passes through the second fixed seat, and the outer ring movable sleeve of the grabbing shaft is provided with a first stop sleeve. The first stop sleeve is detachably connected to the second fixed seat.

[0006] As a preferred embodiment of the above technical solution, the gripping mechanism also includes an air pump, which is connected to an air suction nozzle through an air suction pipe. The air suction nozzle passes through the third fixed seat, and the outer ring movable sleeve of the air suction nozzle is provided with a second stop sleeve, which is detachably connected to the third fixed seat.

[0007] As a preferred embodiment of the above technical solution, a transmission member is provided below the three-axis slide, a mounting plate is fixedly connected to one side of the transmission member, and a position sensor is provided on the inner ring fixed sleeve of the mounting plate.

[0008] As a preferred embodiment of the above technical solution, the conveying member is provided with a partition plate, and every two position sensors are respectively arranged on both sides of the partition plate.

[0009] The beneficial effects of the utility model are:

[0010] 1. After the three-axis slide of the utility model drives the coupling close to the transmission part, the cylinder can push the grab shaft to insert it into the inner ring of the sealing sleeve, and then put the sealing sleeve into the assembly hole of the gas meter. Finally, the grab shaft is pulled back through the first stop sleeve to automatically assemble the sealing sleeve with the gas meter.

[0011] The air pump will create negative pressure in the area between the air nozzle and the second stopper sleeve. When the air nozzle approaches the vertical shaft sleeve, it will be adsorbed on the air nozzle. When the air nozzle reaches the assembly position of the gas meter, turn off the air pump and the vertical shaft sleeve will fall from the air nozzle, thus completing the automatic assembly.

[0012] While improving the assembly efficiency of the vertical shaft sleeve and the sealing sleeve, the assembly quality can be ensured and the labor cost can be reduced. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0018] Example 1

[0019] like Figure 1 and Figure 2 As shown, the gas meter vertical shaft sleeve and sealing sleeve grabbing mechanism includes a three-axis slide 1 and a transmission part 13. The three-axis slide 1 is equipped with a slide 2. The slide 2 is fixedly connected to the first fixed seat 3, the second fixed seat 4 and the third fixed seat 5 on the side away from the three-axis slide 1. The second fixed seat 4 is located below the first fixed seat 3. The inner ring fixed sleeve of the first fixed seat 3 is provided with a cylinder 6. The output end of the cylinder 6 is connected to a grabbing shaft 8 through a coupling 7. The grabbing shaft 8 passes through the second fixed seat 4, and the outer ring movable sleeve of the grabbing shaft 8 is provided with a first stop sleeve 9. The first stop sleeve 9 is detachably connected to the second fixed seat 4.

[0020] Specifically, after the three-axis slide table 1 drives the coupling 7 close to the sealing sleeve, the grasping shaft 8 can be pushed by the cylinder 6 to insert into the inner ring of the sealing sleeve. The sealing sleeve can be grasped and moved to the assembly area of the gas meter through the friction force of the sealing sleeve, and then the sealing sleeve is placed into the assembly hole of the gas meter. Finally, the grasping shaft 8 is pulled back and抵住 the sealing sleeve through the first retaining sleeve 9, so as to assemble the sealing sleeve with the gas meter.

[0021] As Figure 1 shown, the grasping mechanism further includes an air pump. The air pump is connected with an air suction nozzle 11 through an air suction pipe 10. The air suction nozzle 11 penetrates through the third fixing seat 5, and a second retaining sleeve 12 is movably sleeved on the outer circle of the air suction nozzle 11. The second retaining sleeve 12 is detachably connected with the third fixing seat 5.

[0022] Specifically, the cross-section of the vertical shaft sleeve is in a "U" shape. When the air pump sucks air, a negative pressure will be formed in the area between the air suction nozzle 11 and the second retaining sleeve 12. After the air suction nozzle 11 approaches the vertical shaft sleeve, it will adsorb the vertical shaft sleeve on the air suction nozzle 11. When the air suction nozzle 11 reaches the assembly position of the gas meter, the air pump is turned off, and the vertical shaft sleeve will fall off from the air suction nozzle 11, thus completing the assembly.

[0023] Embodiment 2

[0024] As Figure 1 and Figure 2 shown, for the grasping mechanism of the vertical shaft sleeve and the sealing sleeve of the gas meter, compared with Embodiment 1, a conveyor 13 is arranged below the three-axis slide table 1 in this embodiment. One side of the conveyor 13 is fixedly connected with a mounting plate 15, and a position sensor 16 is fixedly sleeved on the inner circle of the mounting plate 15.

[0025] It should be noted that the conveyor 13 adopts a belt conveyor device, and at least two groups of conveyors 13 are arranged, respectively located directly below the coupling 7 and the air suction nozzle 11, and are respectively used for conveying the vertical shaft sleeve and the sealing sleeve. The model of the position sensor 16 is but not limited to: KSW-J18DKEO. After the conveyed vertical shaft sleeve and sealing sleeve move to directly below the coupling 7 and the air suction nozzle 11, the conveyor 13 can be controlled to stop by the position sensor 16. After the conveyed vertical shaft sleeve and sealing sleeve are grasped and removed, the conveyor 13 is controlled to start again.

[0026] As Figure 1 and Figure 2 shown, the conveyor 13 is provided with a partition plate 14, and every two position sensors 16 are respectively arranged on both sides of the partition plate 14.

[0027] It should be noted that the number of the partition plates 14 is set according to the number of the coupling 7 and the air suction nozzle 11, so that the number of the conveying channels of the conveyor 13 is the same as the number of the coupling 7 and the air suction nozzle 11.

[0028] Working principle: The three-axis slide 1 drives the slide 2 to move along the X, Y, and Z axes. When the three-axis slide 1 drives the coupling 7 close to the sealing sleeve, the cylinder 6 can be used to push the grabbing shaft 8 into the inner ring of the sealing sleeve, and the sealing sleeve can be grabbed by the friction force of the sealing sleeve. At the same time, the air pump will form a negative pressure in the area of ​​the vacuum nozzle 11 and the second stop sleeve 12. When the vacuum nozzle 11 approaches the vertical shaft sleeve, it will be adsorbed on the vacuum nozzle 11 and moved to the assembly area of ​​the gas meter. When the second fixed seat 4 and the third fixed seat 5 arrive at the assembly position of the gas meter, the sealing sleeve is placed in the assembly hole of the gas meter. Finally, the grabbing shaft 8 is pulled back to pass through the first stop sleeve 9 to press against the sealing sleeve. At the same time, the air pump is turned off, and the vertical shaft sleeve will fall from the vacuum nozzle 11, thereby assembling the vertical shaft sleeve, the sealing sleeve and the gas meter together.

[0029] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit the same.
