Description

Welding tool for upper head lifting lug

Technical Field

The utility model belongs to the technical field of upper end enclosure processing, and particularly relates to an upper end enclosure lifting lug welding tool.

Background

Polycrystalline silicon is a direct raw material for producing monocrystalline silicon, and is an electronic information base material of semiconductor devices of modern artificial intelligence, automatic control, information processing, photoelectric conversion and the like. The reactor for producing the polycrystalline silicon is mainly used for chips and solar energy, has high requirements on the dimensional accuracy of equipment, and has low efficiency and high cost if eight lower lifting lugs matched with the upper lifting lugs on an upper flange are welded on an upper end socket of the equipment, and each lower lifting lug needs to be precisely measured to determine the position and then welded.

Disclosure of Invention

In order to solve the problems of low welding efficiency and high cost of lifting lugs on the existing upper end enclosure, the utility model provides an upper end enclosure lifting lug welding tool which can effectively improve the welding efficiency of the lifting lugs and reduce the cost.

The technical scheme is as follows: the utility model provides an upper cover lug welding frock, its characterized in that, it includes the base, the base passes through the bolt fastening upper cover, fixed surface installs the center pin in the base center, the center pin top is fixed with the location lid, the location is covered and is fixed with the upper flange, the last lug on the upper flange outer peripheral face is provided with the cover through the connecting plate and is located the equipartition dish outside the upper flange, the equipartition dish bottom is through connecting block connection lug down, be provided with the internal stay structure on the center pin.

The inner supporting structure comprises a disk body fixed on the central shaft and an inner supporting ring fixed on the inner wall of the upper flange, wherein an inclined wedge block is arranged on the outer peripheral surface of the disk body, and the inclined wedge block is matched with an inclined wedge surface and an inclined wedge on the inner peripheral surface of the inner supporting ring.

After the welding tool is adopted, the base fixes the upper end enclosure through the bolts to realize positioning, the peripheral surface of the upper flange is fixed on the positioning cover to realize positioning, the inner supporting structure ensures that the upper flange is coaxial with the upper end enclosure, and the equi-index disc of the peripheral surface of the upper flange can realize accurate positioning of the position of the lifting lug, so that the lifting lug is welded at the accurate position on the upper end enclosure, the precision is ensured, the operation is simple and convenient, the welding efficiency of the lifting lug can be effectively improved, and the cost is reduced; furthermore, the concentricity can be further ensured through the wedge surfaces matched with the inner supporting ring and the disc body, and the structure is stable and reliable.
