Abstract
The utility model is a kind of rotary center positioning device, and wherein locating core is pyramidal structure, can guide fast and positioning tube center.Belong to welding equipment auxiliary machine tool field.Essential characteristic is: automatic Tubesheet welding machine and welding gun connecting rod end cap are fixed, lock-screw is connected with bearing holder (housing, cover) by welding gun connecting rod end cap, centre is equipped with spring, can move up and down, a bearing is equipped with in bearing holder (housing, cover), locating core connecting rod is had, the taper locating core that the assembling of locating core connecting rod bottom and pipe diameter match in bearing.During operation, the taper locating core of rotary center positioning device is put in pipe, moved up and down by built-in spring overhead bearing holder (housing, cover), the guiding of taper locating core, guarantee that the taper locating core conical surface contacts completely with tube wall and just determine tube center, when weld job, taper locating core is static, and bearing holder (housing, cover) have been rotated a circle a complete operation process with automatic welder(welding machine) by bearing with upper-part.
Description
One, technical field
The utility model is that a kind of to be arranged on welding head can 360 degree of center positioning devices rotated, and wherein locating core is pyramidal structure, can guide fast and positioning tube center.Belong to welding equipment auxiliary machine tool field.
Two, background technology
In manufacturings such as boiler, pressure vessel and various heat transmission equipments, it is current topmost structure that tube sheet and heat exchanger tube carry out being welded to connect, because heat exchanger tube is all made up of the pipe of all size, adopt during automatic welding welding and need to rotate a circle along pipe to weld, in addition heat exchanger tube One's name is legion, the length that each pipe end stretches out tube sheet is different, and each pipe joint has a central point, if without rational parts come accurate positioning tube center not only welding quality cannot ensure, efficiency is also very low.
Three, summary of the invention
For above-mentioned shortcoming, the purpose of this utility model is to overcome the problems referred to above, adopt rotary center positioning device of the present utility model can be guided by the taper locating core of end, there is spring can regulate taper locating core length in positioner, the pipe end of various different extension elongation can be met, guarantee that locating core and pipe end closely cooperate, quick position tube center.
The utility model is realized by following technical solution: rotary center positioning device, its essential characteristic is: automatic Tubesheet welding machine and welding gun connecting rod end cap are fixed, lock-screw is connected with bearing holder (housing, cover) by welding gun connecting rod end cap, centre is equipped with spring, can move up and down, be equipped with a bearing in bearing holder (housing, cover), in bearing, have locating core connecting rod, the taper locating core that the assembling of locating core connecting rod bottom and pipe diameter match.During operation, the taper locating core of rotary center positioning device is put in pipe, moved up and down by built-in spring overhead bearing holder (housing, cover), the guiding of taper locating core, guarantee that the taper locating core conical surface contacts completely with tube wall and just determine tube center, when weld job, taper locating core is static, and bearing holder (housing, cover) one week has carried out a complete operation process by bearing with automatic welder(welding machine) with upper-part.
Four, accompanying drawing explanation
Illustrate the three-dimensional mobile self-locking crosshead block diagram of cantilevered described in the utility model: 1-taper locating core, 2-locating core connecting rod, 3-bearing, 4-bearing holder (housing, cover), 5-welding gun connecting rod end cap, 6-spring, 7-lock-screw.
