Description

Technical Field

[0001] The utility model relates to the technical field of pressure vessel cylinder processing, in particular to a tooling assembly capable of double clamping. Background Art

[0002] Pressure vessels are widely used in petrochemical, electric power, food and other industries. Their safety, stability and reliability are crucial to the industrial production process. In order to ensure the manufacturing quality and safety of pressure vessels, clamping fixtures are required to fix and support the pressure vessel cylinder to prevent deformation or damage during manufacturing and transportation. The pressure vessel cylinder clamping fixture is a fixture that can automatically clamp, position and fix, which can greatly improve manufacturing accuracy and efficiency.

[0003] The principle of the clamping fixture assembly of the pressure vessel cylinder is mainly based on the principle of mechanical transmission and positioning. The fixture assembly usually consists of a transmission device, a clamping device and a positioning device. The transmission device can transmit power to the clamping device and the positioning device so that they can work simultaneously. The clamping device can clamp the outer surface or inner surface of the pressure vessel cylinder to fix the cylinder. The positioning device can determine the position and direction of the cylinder to ensure manufacturing accuracy.

[0004] In the process of realizing the present utility model, the inventors found that the prior art had the following problems: 1. The clamping range of the existing pressure vessel cylinder clamping tool assembly is small, and it is unstable during the clamping operation, which can easily cause the pressure vessel cylinder to tilt, resulting in the inability to perform subsequent operations such as opening holes in the cylinder; 2. During the clamping operation, the general clamping tool assembly has a weak locking force of the clamping claws, so the pressure vessel cylinder is prone to shifting and slipping, resulting in a safety hazard of the pressure vessel cylinder falling off, which cannot meet people's needs.
