A positioning and clamping device for lng gas cylinder production line

Abstract

The invention discloses a positioning and clamping device for an LNG gas bottle production line. The positioning and clamping device comprises a moving base, at least one bottle clamping mechanism arranged on the moving base and used for clamping gas bottles in the radial direction, and a driving mechanism for driving the bottle clamping mechanism. A position adjusting mechanism is arranged at the clamping end of the bottle clamping mechanism and comprises a motor support. A bottle moving motor is arranged on the motor support. A driving gear is arranged on an output shaft of the bottle moving motor. Driven shafts parallel to the output shaft of the bottle moving motor are arranged on the portions, on the two sides of the output shaft of the bottle moving motor, of the motor support and provided with driven gears matched with the driving gear. Bottle moving rotating discs used for moving the gas bottles in the axial direction are arranged at the ends of the driven shafts.

Description

technical field [0001] The invention relates to a positioning and clamping device for an LNG cylinder production line. Background technique [0002] The positioning and clamping of LNG cylinders is generally used between two different conveying lines or processing stations. The existing clamping devices generally can only realize positioning and clamping in a single direction in the axial or radial direction. The Chinese patent application "A mechanical gripper based on a synchronous double-link centering movement mechanism" with the publication number CN103213122A discloses a mechanical gripper that uses a double-link mechanism to center and clamp a workpiece. It includes a set of synchronous double-link centering movement mechanism installed under the manipulator frame. When in use, the workpiece to be centered is placed between the V-shaped blocks at the ends of the two mechanisms, and the synchronous double-link centering is driven by the expansion and contraction of th...

AI Technical Summary

Problems solved by technology

However, the centering clamping device can only act radially on the cylindrical workpiece. When it is necessary to axially locate the LNG cylinder on the assembly line, the mechanism cannot meet the requirements.

Because when positioning and clamping the LNG cylinders on the assembly line in the material transfer link, the cylinders will not stop immediately with the stop of the assembly line due to their inertia, and the sliding stop positions of different quality cylinders are also different. Ordinary The clamping device cannot clamp the gas cylinder well, thus affecting the production efficiency of the entire assembly line
