Hole opening tooling for cryostat outer tube

Abstract

The invention discloses a hole-cutting fixture for an outer tube of a cryostat. The hole-cutting fixture comprises an upper component and a lower component which are connected with each other by a bolt, the upper component comprises two parallel arc plates a, both ends of each arc plate are provided with a connecting plate a, the lower component comprises a base plate a, two bottom plates b are arranged on the lower portion of the bottom plate a, two parallel support arc plates are arranged on the bottom plate a, two arc plates b are arranged between the two support arc plates, and both ends of each of the two arc plates b are provided with a connecting plate b. The support arc plates of the lower component are welded with the bottom plate a and the arc plates b, the outer tube can be supported totally, and the hole-cutting size on the same horizontal plane can be more precise. By the aid of the fixture, the outer tube can be stressed more evenly, the roundness of the outer tube is ensured, and the hole-cutting size of the outer tube can be controlled precisely. Besides, the fixture is simple in structure, time-saving and labor-saving.

Description

technical field [0001] The invention relates to a hole opening tool for a thin-walled tube, in particular to a hole opening tool for an outer tube of a cryostat. Background technique [0002] Cryostat, also known as cryogenic bath, is a device used to maintain a continuous low temperature below 0°C, and is widely used in biological experiments, medicine, and school scientific research institutions. In the process of making the outer tube of the cryostat, due to the long length of the outer tube and the large number of holes, the traditional method uses a tape measure to locate each hole to be cut, draws the cutting pattern, and then cuts with a cutting tool. This method is difficult to control the accuracy of the hole size, and it is time-consuming and labor-intensive, especially when the outer tube wall is thinner and the tube length is longer, the outer tube has larger holes and is difficult to control.
