Problems solved by technology

[0002] As we all know, the tee is an auxiliary device used to change the direction of the fluid and is used at the main branch of the main pipeline. It has been widely used in the field of fluid direction change; the existing tee generally uses a saddle skirt The branch of the side structure is connected to the main pipe, and the existing branch structure is connected by manual welding. The positioning accuracy of the pipe is poor, that is, the discreteness is large, and it is difficult to meet the position accuracy requirements during welding, and the appearance after welding is also difficult to meet. Requirements, after welding, the relative position error between the welded pipes is large, there is a certain amount of scrap after welding, and automatic welding is also difficult to achieve due to low positioning accuracy. In short, the existing tee production process It is difficult to meet the increasing demand for product quality and appearance

Embodiment Construction

[0011] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0012] Such as Figure 1 to Figure 3 As shown, an internal and external double positioning tee of the present invention includes a main pipe 1 and two sets of branch pipes 2, and also includes a cylindrical pin 3 and a chamfered pin 4. The pin is placed on the side wall of the main pipe, and the main pipe and two sets of branch pipes limit five degrees of freedom; it can be completely positioned by a typical side with two pins, which determines the position of the tee in the welding fixture, and the three ports are connected with the outside world The fit of the joint adopts excessive fit, and the positioning tee can have several different forms. The angle between the thr...

Abstract

The invention relates to the technical field of mechanical manufacturing accessory devices, in particular to an inside and outside double-positioning tee. According to the double-positioning tee, theaccuracy of a position required to be welded is improved, so that the qualification rate of a forming pipe after welding is improved; the welding quality and the beautiful degree of a welded surface are improved; the double-positioning tee comprises a main pipe and two groups of branch pipes as well as cylindrical pins and side-eat pins; the cylindrical pins are installed at the intersection positions between the main pipe and the center lines of the two groups of the branch pipes, and the side-eat pins are arranged on the side wall of the main pipe; and five degrees of freedom are limited bythe main pipe and the two groups of the branch pipes.
