[0002] Automatic gas distribution devices for gas cylinders are widely used in the fields of medical treatment, fire protection, aviation, petrochemicals, metallurgy, and shipping for the storage and transportation of various gases. Through an automated control system, the automatic gas distribution device for gas cylinders can automatically complete the gas distribution work according to a preset gas distribution plan, greatly improving the efficiency and accuracy of gas distribution. The existing automatic gas distribution devices for gas cylinders have a low degree of automation. During the gas distribution process, after the gas cylinder is placed on the gas cylinder bracket, it is necessary to manually operate the clamping device to position and clamp the gas cylinder, and then transfer the gas cylinder bracket together with the gas cylinder to the gas distribution station for weighing and gas distribution. This not only wastes manpower, but also affects the full automation of the automatic gas distribution device for gas cylinders. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is to provide an automatic positioning and clamping device for gas cylinders which can automatically position and clamp gas cylinders.

[0006] Furthermore, the transmission component includes two transmission wheels fixedly mounted on two forward and reverse threaded screw rods, and a synchronous belt is connected between the two transmission wheels.

[0007] Furthermore, an overrunning clutch is installed on one of the forward and reverse threaded screw rods, and the clamping shaft is fixedly connected to the output shaft of the overrunning clutch.

[0008] Furthermore, a torque limiter is connected to the rotating shaft of the motor, and the clamping sleeve is fixedly connected to the output shaft of the torque limiter.

[0012] Working principle and process:

[0013] When in use, the cylinder extends and, under the guidance of the linear guide and the slider, pushes the mobile frame to the rightmost end. At this time, the clamping shaft is just clamped into the bayonet on the clamping sleeve. When the gas cylinder passes through the two splints and is placed on the gas cylinder bracket, the motor is driven to rotate the clamping sleeve, thereby driving the forward and reverse threaded screws to rotate through the clamping shaft. Under the cooperation of the two transmission wheels and the synchronous belt, the two forward and reverse threaded screws rotate synchronously, thereby driving the two sets of moving nuts to move relative to each other, and then driving the two splints to move relative to each other, positioning and clamping the gas cylinder, and then the cylinder retracts, driving the mobile frame to move to the left, thereby disengaging the clamping shaft from the bayonet on the clamping sleeve, so that the mobile frame can smoothly drive the gas cylinder to the gas weighing station.

[0019] The following is a further description of the embodiments of the present invention with reference to the accompanying drawings:

[0022] When in use, the displacement driving component is in action, and under the cooperative guiding action of the linear guide 4 and the slider 8, the movable frame 7 is pushed to the rightmost end. At this time, the card shaft 17 is just stuck in the bayonet 18 on the card sleeve 19. When the gas cylinder 5 passes through the two plywood 12 and is placed on the gas cylinder bracket 10, the motor 22 is actuated to drive the card sleeve 19 to rotate, thereby driving the positive and negative threaded screw rods 13 to rotate through the card shaft 17. Under the transmission action of the transmission component, the two positive and negative threaded screw rods 13 rotate synchronously, thereby driving the two sets of moving nuts 14 to move relative to each other, and then driving the two plywood 12 to move relative to each other, positioning and clamping the gas cylinder 5, and then the displacement driving component reverses and drives the movable frame 7 to move to the left, thereby disengaging the card shaft 17 from the bayonet 18 on the card sleeve 19, and enabling the movable frame 7 to smoothly drive the gas cylinder 5 to the gas distributing station.

[0027] Furthermore, an overrunning clutch 16 is installed on one of the forward and reverse threaded screws 13, and the clamping shaft 17 is fixedly connected to the output shaft of the overrunning clutch 16.

[0031] Furthermore, the automatic telescopic component 2 is a cylinder, which has a simple structure and is easy to control.

[0032] It is particularly noted that in the description of the present invention, the directions or positional relationships indicated by the terms "front", "rear", "left", "right", etc. are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than requiring the present invention to be constructed and operated in a specific direction.
