Description

Technical Field

[0001] The invention relates to the field of processing end-wrapped pipe components, in particular to a welding tool for the end-wrapped pipe component and a cap. Background Art

[0002] The end cap is the core pressure-sensing element of a pressure gauge. It is typically C-shaped and has a hollow, circular structure. Pressure is generated by stamping the inner cavity of the end cap, causing deformation at the end of the end cap to drive a transmission mechanism to indicate pressure. The welding accuracy of the end cap cap directly affects the installation of the end cap assembly. Older versions of the end cap cap welding tooling were simple and subject to significant wear. The welding accuracy of the cap cap could not be guaranteed, and the cap cap could easily become skewed after welding, failing to meet the required dimensions for product installation and requiring secondary rework. Summary of the Invention

[0003] The purpose of the present invention is to provide a welding fixture for end-tube and end-cap, which can realize the combined welding of the end-tube assembly and the end-cap, improve the processing qualification rate and precision, avoid the skew defect after the end-cap is welded, and meet the use requirements.

[0006] The fixed seat 2 and the slider seat 4 are both fixed to the bottom plate by connecting members, and the slider seat 4 has a hollow slide groove with an upper opening, and the slider 3 is slidably arranged in the hollow slide groove. The spring 6 is arranged between the slider and the slider seat to provide an elastic pre-tightening force for the slider to move vertically upward. The slider seat has left and right through side windows, and the limit pin passes through the left and right through side windows. The limit pin can slide in the vertical direction in the side windows;

[0007] The limiting pin is fixed to the slider as a whole, and limits the slider through the side window;

[0008] The fixing seat is used to fix and install the end tube assembly, and the upper end surface of the slider forms a positioning groove, which is adapted to the shape of the headstock and is used to fix and install the headstock. When the end tube assembly and the headstock are respectively installed and fixed in the fixing seat and the positioning groove, the end tube assembly can be pressed on the headstock, forming elastic compression with the spring to assist in welding the end tube assembly and the headstock.

[0009] Furthermore, the connecting member is a bolt.

[0010] Furthermore, the side window is a vertical waist-shaped hole.

[0011] Optionally, the base plate (1) is a rectangular plate, and threaded holes are provided on the base plate for mounting the fixing seat (2) and the slider seat (4).

[0012] Optionally, the fixing seat has a U-shaped groove for installing and fixing the neck of the end tube assembly.

[0013] Optionally, the bottom plate is provided with a plurality of mounting holes or waist-shaped holes, which can adjust the mounting positions of the fixing seat and the slider seat to ensure that the relative position of the end tube assembly and the header meets the requirements;

[0014] Optionally, the slider (3) is a component, and the positioning groove of each slider in the component has a different size, which can better ensure that the size meets the requirements after welding.

[0015] The working principle is:

[0016] See also Figure 3 The utility model provides a welding fixture for end-tube headers, comprising a base plate (1), a component fixing seat (2), a slider seat (4), a slider (3), a screw (5), a spring (6) and a limiting rod (7);

[0017] In actual use, such as Figure 4 As shown, the header ( Figure 2 ) is placed snugly in the square groove at the upper end of the slider (3), and the end tube assembly ( Figure 1 ) Press snugly Figure 4 The position is installed on the component fixing seat (2) from top to bottom.

[0018] like Figure 5 As shown, the slider (3) at this time pushes the head and the end tube assembly to fit tightly together under the action of the spring (6), and then the soldering method of soldering iron can be used to solder the head and the end tube assembly. Figure 5 The welding is completed at the welding position shown; after the welding is completed, the assembly can be withdrawn upward along the vertical groove of the component fixing seat (2).

[0019] The end pipe and cap welding fixture can ensure that the relative position size of the end pipe assembly and the cap meets the requirements, effectively prevent the cap from being skewed after welding, improve the processing qualification rate and accuracy, and meet the size requirements required for product installation.

[0020] The advantages of the present invention are that the present invention can realize the combined welding of the end-tube assembly and the ferrule, improve the processing qualification rate and precision, avoid the skew defect after the ferrule is welded, and meet the use requirements.
