A fixture for turning high-pressure gas cylinders

Abstract

The invention provides a clamp for performing turning on a high pressure gas cylinder, and relates to the technical field of mechanical processing tools. The clamp comprises a rotating support and a telescopic chuck, wherein the rotating support comprises a base, a supporting bearing arranged in the base and a support body, the support body is connected with an inner ring of the supporting bearing, the outer ring of the supporting bearing is connected with the base, the telescopic chuck comprises a cylinder barrel, a telescopic rod and a claw, the claw is connected with the front end of the telescopic rod, the telescopic rod is arranged in the cylinder barrel, and rotating-prevention mechanisms matched with each other are arranged on the cylinder barrel and the telescopic rod. Large-scale reformation on a lathe is not needed when the clamp is used for performing turning on the high pressure gas cylinder, only the telescopic rod and the claw need to be pushed by a pushing device of the lathe, the weight of the telescopic rod and the claw is light, and the friction force between the telescopic rod and the cylinder barrel is small, so that the pushing device of the lathe can push the telescopic rod and the claw with a smaller push force, the clamp is small in abrasion during use, and the service life is long.

Description

technical field [0001] The invention relates to the technical field of machining tools, in particular to a fixture for turning high-pressure gas cylinders. Background technique [0002] The production process of high-pressure gas cylinders includes seamless steel pipe cutting and blanking, high-temperature bottle bottom collection, bottle bottom scraping, high-temperature bottle mouth closing, cylinder inner wall shot blasting, bottle mouth turning and other processes. [0003] In the actual production process, due to the large volume and special shape of the gas cylinder, the ordinary lathe cannot realize the turning process of the gas cylinder. The Chinese invention patent No. 01277981.4 discloses a lathe for turning the gas cylinder. The device pushes the sliding table, the spindle box and the chuck to move towards the support frame, so that the gas cylinder is clamped between the chuck and the support frame.

Problems solved by technology

[0003] In the actual production process, due to the large volume and special shape of the gas cylinder, the ordinary lathe cannot realize the turning process of the gas cylinder. The Chinese invention patent No. 01277981.4 discloses a lathe for turning the gas cylinder. The device pushes the sliding table, the spindle box and the chuck to move towards the support frame, so that the gas cylinder is clamped between the chuck and the support frame. Although the lathe has the function of turning the gas cylinder, it needs to The ordinary lathe undergoes large-scale transformation. Since the slide table, spindle box and chuck of the lathe are very heavy together, the propulsion device of the lathe needs to provide a large thrust to push the above components. In addition, due to the spindle box and The chucks are all set on the slide table, and the wear of the slide table and the guide rail is very large during the sliding process, resulting in a short service life of the slide table and guide rail
