Abstract
The utility model discloses a rapid positioning device for a suspension type automatic argon arc welding machine for a tube sheet. The rapid positioning device comprises a welding machine, a tube sheet and a welded tube fitting, wherein the welding machine comprises a main shaft of the welding machine, a machine case of the welding machine and a welding gun; the positioning device also comprises a positioning shaft head, a tube expanding device and a power tube; the positioning shaft head is arranged in the orifice of the welded tube fitting; the tube expanding device and the positioning shaft head are fixedly connected and are arranged in the welded tube fitting; the power tube is sheathed in the main shaft of the welding machine and is penetrated through the machine case of the welding machine and the positioning shaft head to be communicated with the tube expanding device; and a high pressure fluid inlet which is communicated with the power tube is arranged on the machine case of the welding machine. According to the technical scheme, the system temperature of the positioning device can be reduced, and the positioning is ensured to be reliable and stable. The rapid positioning device can be used for rapidly positioning the welding machine and the welded tube fitting, can realize the accurately concentric positioning of the welding gun and the welded tube fitting, ensures the radial distance between the welding gun and the tube fitting to be unchanged when the welding gun is used for rotary welding around the welded tube fitting so as to ensure the welding quality.
Description
Technical field
Fast-positioning device when the utility model relates to a kind of welding machine and welded by welded tube spare refers to a kind of suspended automatic tube sheet argon arc welding machine fast-positioning device particularly.
Background technology
Suspended automatic tube sheet argon arc welding machine is the welding machine special of joint welding that is used for heat exchanger tube and the tube sheet of large heat exchanger.During welding, the welding gun of welding machine need be around being rotated by the weldering heat exchanger tube, to accomplish the welding of 360 ° of circular welds.And during welding, higher welding temperature can make by welded tube spare trickle deformation takes place, and influences welding quality.
Thereby welding machine needs a kind of rapid and reliable positioner, can realize welding gun accurately with heat exchanger tube concentric locating, it is constant to guarantee that welding gun rotate when welding welding gun and weld seam radial distance around heat exchanger tube, with the assurance welding quality.
Summary of the invention
The purpose of the utility model will overcome the existing in prior technology deficiency exactly, and a kind of suspended automatic tube sheet argon arc welding machine fast-positioning device is provided.
For realizing above-mentioned purpose; The suspended automatic tube sheet argon arc welding machine fast-positioning device that the utility model designed; Comprise welding machine, tube sheet and by welded tube spare, said welding machine comprises welding machine main shaft, welding machine cabinet and welding gun, said positioner also comprises location spindle nose, pipe-expander and power pipe; Said location spindle nose is arranged on by in the mouth of pipe of welded tube spare; Said pipe-expander is fixedly connected and is placed in by in the welded tube spare with the location spindle nose, and said power pipe box is in the welding machine main shaft and pass the welding machine cabinet and be connected with pipe-expander with the location spindle nose, and said welding machine cabinet is provided with the high-pressure fluid that is connected with the power pipe and enters the mouth.
Preferably, said pipe-expander, location spindle nose, power pipe, welding machine main shaft with by the equal concentric setting of welded tube spare.
The beneficial effect of the utility model is: adopt such scheme, can reduce the system temperature of positioner, guarantee to locate reliable and stable.The utility model can with welding machine with by the quick location of welded tube spare, can realize welding gun accurately with by the concentric locating of welded tube spare, guarantee welding gun when changing by welded tube spare rotating welding welding gun with constant, to guarantee welding quality by welded tube spare radial distance.
