Description

Technical Field

[0001] This utility model relates to the field of gas cylinders, and in particular to an auxiliary device for correcting the coaxiality of automatic gas cylinder assembly. Background Technology

[0002] Gas cylinders are a type of pressure vessel with a bottle-shaped main structure, generally filled with gas (which can be compressed gas, liquefied gas, dissolved and adsorbed gas, etc.) and are portable. They are a type of pressure-bearing equipment with explosion hazards, and the medium they contain is generally flammable, explosive, toxic, and highly corrosive. According to the manufacturing method, they can be divided into welded gas cylinders, piped gas cylinders, stamped and drawn gas cylinders, and spiral wound gas cylinders.

[0003] In the current automatic assembly process of gas cylinders, the axis is easily offset due to workpiece positioning deviation, mechanical vibration, or assembly error. This is not conducive to the coaxiality of the cylinder body, valve, and seals, and can also cause seal deformation due to compression, which will affect the sealing performance. To address these issues, we propose an auxiliary device for coaxiality correction in automatic gas cylinder assembly. Utility Model Content

[0004] The purpose of this invention is to provide an auxiliary device for correcting the coaxiality of gas cylinders during automatic assembly, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An auxiliary device for coaxiality correction during automatic assembly of gas cylinders includes a housing. The front of the housing has two sliding openings. The inner wall of each sliding opening is slidably connected to two sliding rods. The sides of the two sets of sliding rods that are close to each other are connected to connecting blocks. The sides of the two sets of connecting blocks that are close to each other are connected to correction plates. The inner wall of the housing is provided with two pushing mechanisms. The inner side wall of the housing is connected to a moving part.

[0007] In a further embodiment, the movable component includes a fixed plate connected to the housing, a pressure bearing is embedded on the upper surface of the fixed plate, a threaded rod is connected to the inner ring of the pressure bearing, a motor is connected to the bottom end of the threaded rod, the bottom surface of the motor is connected to the inner bottom wall of the housing, and a threaded cylinder is threadedly connected to the outer surface of the threaded rod.

[0008] In a further embodiment, each of the pushing mechanisms includes a push plate, and a push rod is hinged to one side of each of the two push plates that are close to each other by a pin. One end of each push rod is hinged to the outer surface of the threaded cylinder by a pin, and the front of each push plate is connected to one end of a slide rod.

[0009] In a further embodiment, a process label is provided on the front of the box, and the back of the process label is connected to the front of the box.

[0010] In a further embodiment, a control switch is provided on the right side of the housing, and the left side of the control switch is connected to the right side of the housing.

[0011] In a further embodiment, mounting plates are connected to both the left and right sides of the housing, and each mounting plate has two through holes on its upper surface.

[0012] In a further embodiment, a rolling bearing is connected to the top end of the threaded rod, a connecting plate is connected to the outer surface of the rolling bearing, and the back of the connecting plate is connected to the inner side wall of the housing.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This device utilizes the cooperation of a motor and a threaded rod to facilitate the rotation of the threaded rod within the pressure bearing. Then, the connection between the threaded rod and the threaded cylinder allows the threaded cylinder to move the pin component. Subsequently, the hinged relationship between the pin component, push rod, and pin shaft facilitates the movement of the push plate when the push rod tilts. Following this, the cooperation between the push plate and the sliding rod allows the sliding rod to push the connecting block, bringing the correction plate closer to the gas cylinder and facilitating the correction of the gas cylinder. This solves the problem of sealing performance being affected by the compression deformation of the seals due to axial misalignment. Attached Figure Description

[0023] Please see Figure 1-4 In this utility model, an auxiliary device for coaxiality correction of automatic assembly of gas cylinders includes a housing 6. The front of the housing 6 has two sliding openings 1. The inner wall of each sliding opening 1 is slidably connected to two sliding rods 10. The sides of the two sets of sliding rods 10 that are close to each other are connected to connecting blocks 4. The sides of the two sets of connecting blocks 4 that are close to each other are connected to correction plates 3. The inner wall of the housing 6 is provided with two pushing mechanisms 8. The inner side wall of the housing 6 is connected to a moving part 7.

[0024] The movable component 7 includes a fixed plate 701 connected to the housing 6. A pressure bearing 703 is embedded on the upper surface of the fixed plate 701. A threaded rod 707 is connected to the inner ring of the pressure bearing 703. A motor 702 is connected to the bottom end of the threaded rod 707. The bottom surface of the motor 702 is connected to the inner bottom wall of the housing 6. A threaded cylinder 704 is threadedly connected to the outer surface of the threaded rod 707. The cooperation between the motor 702 and the threaded rod 707 facilitates the rotation of the threaded rod 707 inside the pressure bearing 703. Then, the connection between the threaded rod 707 and the threaded cylinder 704 facilitates the movement of the pin component 803 driven by the threaded cylinder 704.

[0025] Each pushing mechanism 8 includes a push plate 801. The two push plates 801 are close to each other on one side and a push rod 802 is hinged to them by a pin 804. One end of each push rod 802 is hinged to the outer surface of the threaded cylinder 704 by a pin 803. The front of each push plate 801 is connected to one end of the slide rod 10. The hinge relationship of the pin 803, push rod 802 and pin 804 makes it easy for the push rod 802 to move the push plate 801 when it tilts. Then, according to the cooperation between the push plate 801 and the slide rod 10, the slide rod 10 can push the connecting block 4 to move the correction plate 3 closer to the gas cylinder, and make it easy to correct the gas cylinder. This solves the problem of the sealing performance being affected by the compression deformation of the seal caused by the axial misalignment.

[0026] A process label 2 is provided on the front of the housing 6, and the back of the process label 2 is connected to the front of the housing 6. The process label 2 makes it easy to understand the operation process of the device. A control switch 5 is provided on the right side of the housing 6, and the left side of the control switch 5 is connected to the right side of the housing 6. The control switch 5 makes it easy to control the start of the device. Mounting plates 9 are connected to both sides of the housing 6. Each mounting plate 9 has two through holes 11 on its upper surface. The design of the mounting plates 9 and the through holes 11 makes it easy to install the device in the usage position. A rolling bearing 706 is connected to the top of the threaded rod 707. A connecting plate 705 is connected to the outer surface of the rolling bearing 706. The back of the connecting plate 705 is connected to the inner side wall of the housing 6. The design of the rolling bearing 706 and the connecting plate 705 makes it easier to increase the stability of the threaded rod 707.

[0027] The working principle of this utility model is as follows:

[0028] In use, the power provided by the motor 702 first drives the threaded rod 707 to rotate inside the pressure bearing 703. According to the cooperation between the threaded rod 707 and the threaded cylinder 704, when the threaded cylinder 704 moves on the surface of the threaded rod 707, it drives the pin 803 to move. At the same time, through the hinge relationship between the pin 803, the push rod 802 and the pin 804, the push plate 801 is pushed to drive the slide rod 10 to move. Then, by using the connection between the slide rod 10 and the connecting block 4, the correction plate 3 can be pushed to perform the correction work on the gas cylinder.
