Technical Field

The invention relates to a tool clamp, in particular to a tool clamp for electron beam welding of an ion cyclotron limiter.

Background

The ion cyclotron limiter is one of important parts in nuclear fusion, and is formed by welding copper alloy with excellent high-temperature strength by electron beams. When the special-shaped water channel and the special-shaped water channel cover plate are welded by the electron beam, the electron beam needs to be kept perpendicular to the tangential direction of the cambered surface of the welding seam of the special-shaped water channel for welding so as to ensure the welding continuity and the welding quality. However, the ion cyclotron limiter is irregular in shape, so that the ion cyclotron limiter needs to be clamped for many times, a special-shaped water channel needs to be welded for many times, and a large amount of assembly time and cost are consumed.

Disclosure of Invention

The invention aims to provide a tool clamp which can effectively reduce the assembly times and ensure that an electron beam is kept perpendicular to the arc surface of a special-shaped water channel welding line for welding in the electron beam welding process of a special-shaped water channel of an ion cyclotron limiter.

A tool clamp for electron beam welding of an ion cyclotron limiter comprises a Y-shaped support, wherein a rotating shaft penetrates through the center of the bottom of the Y-shaped support, rotating shaft flanges are sleeved at two ends of the rotating shaft, the Y-shaped support and the rotating shaft flanges are positioned and clamped through positioning pins and bolts, a three-jaw clamping groove is formed in the surface, extending out of the rotating shaft flanges, of the rotating shaft, and the three-jaw clamping groove is matched with a three-jaw chuck of an electron beam welding machine; a supporting table is erected at the top of the Y-shaped support, the special-shaped water channel cover plate and the special-shaped water channel are embedded in the supporting table, a positioning pin and a bolt are arranged on the side wall of the supporting table, the supporting table is fixed on the Y-shaped support through the positioning pin, and the special-shaped water channel cover plate are clamped in the supporting table through the bolt.

The special-shaped water channel welding device is simple in structure and convenient to use, can realize one-time welding of irregular annular welding seams of the special-shaped water channel and the special-shaped water channel cover plate in the ion cyclotron limiter, does not need repeated vacuum unloading and clamping, ensures the purity of the welding seams of the special-shaped water channel and the special-shaped water channel cover plate (made of copper alloy materials), and greatly improves the welding production efficiency and the product quality.

Detailed Description

Referring to fig. 1, the tool clamp for electron beam welding of the ion cyclotron limiter provided by the invention comprises a Y-shaped support 1, wherein a rotating shaft 2 penetrates through the center of the bottom of the Y-shaped support 1, rotating shaft flanges 3 are sleeved at two ends of the rotating shaft 2, the Y-shaped support 1 and the rotating shaft flanges 3 are positioned and clamped through positioning pins 4 and bolts 5, a three-jaw clamping groove 6 is formed in the surface of the rotating shaft 2, which extends out of the rotating shaft flanges 3, and the three-jaw clamping groove 6 is matched with a three-jaw chuck (not shown) of an electron beam welding machine; a supporting table 7 is erected at the top of the Y-shaped support 1, a special-shaped water channel cover plate 8 and a special-shaped water channel 9 are embedded in the supporting table 7, the special-shaped water channel 9 surrounds the special-shaped water channel cover plate 8, positioning pins 4 and bolts 5 are arranged on the side wall of the supporting table 7, the supporting table 7 is fixed on the Y-shaped support 1 through the positioning pins 4, and the special-shaped water channel 9 and the special-shaped water channel cover plate 8 are clamped in the supporting table 7 through the bolts 5.

The working process is as follows: the three-jaw chuck of the electron beam welding machine clamps the three-jaw clamping groove 6 of the rotating shaft 2, the rotation of the three-jaw chuck is adopted to drive the rotating shaft 2 to rotate, so that the Y-shaped support 1 and the supporting table 7 on the Y-shaped support are coaxially rotated, the axis of the rotating shaft 2 is concentric with the large arc section of the special-shaped water channel cover plate 8 and the special-shaped water channel 9 on the supporting table 7, the positions of the special-shaped water channel cover plate 8 and the special-shaped water channel 9 can be continuously changed in a rotary welding mode, meanwhile, the welding programming is matched, the irregular annular welding seam of the special-shaped water channel cover plate 8 and the special-shaped water channel 9 can be welded at one time, repeated clamping of the special-shaped water channel cover plate 8 and the special-shaped water channel 9 is not required to be repeatedly vacuumized, the welding seam purity of the special-shaped water channel cover plate 8 and the special-shaped water channel 9 is ensured, and the welding production efficiency and the product quality are greatly improved. In addition, the Y-shaped support 1 is connected with the support table 7 and the rotating shaft flange 3 through the positioning pins and the bolts, and the Y-shaped support has the advantages of being convenient to disassemble and assemble, saving production cost and the like during batch production.

Example 1

In this embodiment, a hollow bottom plate 10 for supporting the special-shaped water channel cover plate 8 and the special-shaped water channel 9 is disposed in the middle of the bottom surface of the support table 7 along the length direction. The purpose is that the hollow-out bottom plate 10 is utilized to facilitate the placement and support of the special-shaped water channel cover plate 8 and the special-shaped water channel 9, and the hollow-out design can reduce the weight of the tool.
