Problems solved by technology

Although the general fixture can move horizontally and vertically in the plane, it cannot pre-determine the position of the bottle body. Therefore, a centering mechanism is required to make the axial symmetry line of the bottle and the center line of the fixture pairing center line basically in the same plane. However, two devices are used respectively. To complete the centering and clamping of the bottle body, it not only reduces the working efficiency of the assembly line, but also increases the risk of the device impacting the gas cylinder, and because the clamp is axially clamping the gas cylinder, the impact on the surface of the gas cylinder is increased. force, affecting the quality of the gas cylinder

Embodiment 2

[0019] Embodiment 2 differs from Embodiment 1 in that the telescopic mechanism 35 includes an outer sleeve and an inner rod that are partly sheathed together, the outer sleeve is axially provided with several through holes, and the inner rod is provided with Matching bolt holes, connecting bolts pass through the through holes and bolt holes and are locked by nuts.

Embodiment 3

[0020] Embodiment 3 is different from Embodiment 1 in that the telescopic mechanism 35 is an air cylinder with adjustable stroke.

[0021] Mechanism principle: This structure adopts a nested structure, which mainly uses the taper of the head and tail of the gas cylinder to take the gas cylinder. When in use, move the clamping device to the gas cylinder, so that the two clamping mechanisms 3 are located at both ends of the gas cylinder, and then the motor drives the screw 41 to rotate, so that the clamping base 31 moves relative to the axial direction along the guide rail, from the gas cylinder The head and the tail of the bottle are inserted respectively. When the radio eyes 43 on the outer surfaces of the two clamping mechanisms 3 are completely blocked by the gas cylinder, a signal is sent to the motor 42 to stop the motor 42 and the clamping is completed. That is, the clamping device can be moved to move the cylinder to the desired position. When the cylinder needs to be u...

Abstract

The invention discloses a clamping device which can reduce surface stress deformation of gas cylinders and can be applied to various specifications of LNG cylinders on an assembly line. The clamping device comprises a rack, a sliding rail and two clamping mechanisms, wherein the length of the sliding rail is greater than those of the gas cylinders, and the two clamping mechanisms are arranged on the sliding rail side by side. The rack is provided with a power device driving clamping bases to slide. Each clamping mechanism comprises the corresponding clamping base which is movably arranged on the sliding rail, the lower portion of each clamping base is provided with an adjusting rail in the direction perpendicular to the sliding rail, two sliding bases are arranged on each adjusting rail in a clamped mode, an upper clamping block is arranged on the lower portion of each sliding base, a telescopic mechanism is arranged on the lower portion of each upper clamping block, a lower clamping block is arranged at the bottom end of each telescopic mechanism, each telescopic mechanism is arranged between the corresponding upper clamping block and the corresponding clamping block, and the clamping surface of each upper clamping block and the clamping surface of each lower clamping block are respectively in an arc shape.

Description

technical field [0001] The invention relates to a clamping device for an LNG gas cylinder, in particular to a gas cylinder positioning and clamping device suitable for an LNG gas cylinder production line. Background technique [0002] The transfer and transportation of the bottle body on the LNG gas cylinder production line is generally triggered by the bottle body to trigger the sensor to stop the assembly line, and then move to the corresponding position after being clamped by the clamp. However, due to the inertia of the bottle itself, the LNG bottle can continue to slide for a certain distance before stopping, and the sliding distance is uncontrollable for different objects, and the position of the bottle is also uncontrollable. Although the general fixture can move horizontally and vertically in the plane, it cannot pre-determine the position of the bottle body. Therefore, a centering mechanism is required to make the axial symmetry line of the bottle and the center lin...
