Technical Field

[0001] The utility model relates to the technical field of terminal welding, in particular to a terminal welding fixture inside a shell. Background Art

[0002] When currently welding a terminal inside a shell, it is necessary to place the terminal inside the shell for operation. Since the shell is semi-closed, the operating space inside the shell is small, and the terminal size is small and not easy to grasp. Therefore, it is difficult to align the welding points of the two, resulting in difficult welding of the terminal and the shell. Summary of the Utility Model

[0003] The purpose of the utility model is to provide a terminal welding fixture inside a shell, which overcomes the above defects, can position the terminal on the shell, align the welding points of the two, and reduces the difficulty of welding the terminal inside the shell.

[0004] To achieve the above object, the solution of the utility model is as follows:

[0005] A terminal welding fixture inside a shell is used to be placed inside a welding machine. The welding machine includes a welding workbench, on which a welding machine head is arranged. The welding machine head is provided with a floating electrode for lifting and adjusting. Below the floating electrode, a fixed electrode is arranged at intervals. Both the floating electrode and the fixed electrode have working centers. The shell has an inner cavity and an opening on one side. The welding fixture includes a shell positioning component and a terminal positioning block. The shell positioning component is arranged on the welding workbench and is provided with a positioning groove located between the floating electrode and the fixed electrode for the shell to be embedded. The lower end of the shell has a first welding point. When the shell is embedded in the positioning groove, its lower end is located between the fixed electrode and the floating electrode, and the working centers of the floating electrode and the fixed electrode coincide with the first welding point, and the fixed electrode abuts against the lower surface of the lower end of the shell. The terminal positioning block is used for horizontal positioning and embedding in the inner cavity, and is provided with a terminal fixing groove and a welding window. The terminal fixing groove is used for the horizontal positioning and embedding of one end of the terminal, and the other end of the terminal extends to the welding window. The welding window is used to expose the other end of the terminal below the floating electrode when the terminal positioning block is embedded in the inner cavity. The part of the terminal located in the welding window is provided with a second welding point. When the terminal positioning block is embedded in the inner cavity, the second welding point and the first welding point are aligned and fitted, and the floating electrode descends into the welding window and the fixed electrode jointly weld the first welding point and the second welding point.

[0006] Further, the shell positioning component includes a shell positioning block and a base. The positioning groove is opened on the shell positioning block, and the shell positioning block is fixed on the upper surface of the base, and the base is placed on the welding workbench.

[0007] Furthermore, a moving space is provided in the base. The moving space is located below the positioning groove and is communicated with the positioning groove. The moving space is for the fixed electrode to be placed below the positioning groove. When the housing is placed in the positioning groove, the fixed electrode abuts against the lower surface of the lower end of the housing.

[0008] Furthermore, there is a support platform between the positioning groove and the moving space. The support platform is used to support the lower end of the housing when the housing is embedded in the positioning groove.

[0009] Furthermore, the support platform has a relief notch. The positioning groove and the moving space are communicated through the relief notch. The fixed electrode passes through the relief notch and abuts against the lower surface of the lower end of the housing when the housing is placed in the positioning groove.

[0010] Furthermore, the opening of the housing faces the floating electrode side. The floating electrode is arranged in a vertical Z shape. Its upper end is arranged to be lifted and lowered on the welding machine head, and its lower end extends into the inner cavity of the housing and is located above the welding window.

[0011] Furthermore, the lower end of the floating electrode is in an inclined conical shape, and the area of the lower end surface of the floating electrode is smaller than the area of the upper end surface of the fixed electrode.

[0012] Furthermore, the housing is in a bowl shape. When the housing is embedded in the positioning groove, its opening faces to the right. The floating electrode enters the inner cavity from the opening. When the terminal positioning block is embedded in the inner cavity, its left side abuts against the left side wall of the inner cavity, and its front and rear sides respectively abut against the front side wall and the rear side wall of the inner cavity. The right side of the terminal positioning block extends out of the inner cavity from the opening.

[0013] After adopting the above scheme, the beneficial effects of the present utility model are as follows:

[0014] In this utility model, the housing is horizontally positioned and embedded in the housing positioning groove for positioning, so that the working centers of the floating electrode and the fixed electrode are aligned with the first welding point of the housing. Then the terminal is horizontally positioned and embedded on the terminal positioning block. The second welding point of the terminal is located within the welding window. When the terminal positioning block is embedded in the inner cavity of the housing, the first welding point and the second welding point are aligned and fitted. At this time, the second welding point is also aligned with the working centers of the floating electrode and the fixed electrode. The floating electrode descends and welds the first welding point and the second welding point together with the fixed electrode, thereby positioning and welding the terminal on the housing. The operation is simple, the structure is simple, and the difficulty of welding the terminal in the housing is reduced. Description of the Drawings

When the housing 30 is embedded in the positioning groove 112, its lower end is located between the fixed electrode 24 and the floating electrode 23, and the working centers of the floating electrode 23 and the fixed electrode 24 coincide with the first welding point 33, and the fixed electrode 24 abuts against the lower surface of the lower end of the housing 30; the terminal positioning block 12 is used for horizontal positioning and embedding in the inner cavity 31, and a terminal fixing groove 121 and a welding window 122 are formed therein. The terminal fixing groove 121 is used for one end of the terminal 40 to be horizontally positioned and embedded to limit the overall horizontal movement of the terminal 40. The other end of the terminal 40 extends to the welding window 122. The welding window 122 is used to expose the other end of the terminal 40 below the floating electrode 23 when the terminal positioning block 12 is embedded in the inner cavity 31.

[0026] Specifically, the housing 30 is in a bowl shape, and when the housing 30 is embedded in the positioning groove 112, its opening 32 faces rightward, the floating electrode 23 enters the inner cavity 31 from the opening 32. When the terminal positioning block 12 is embedded in the inner cavity 31, its left side abuts against the left side wall of the inner cavity 31, and its front and rear sides respectively abut against the front side wall and the rear side wall of the inner cavity 31 to limit the horizontal movement of the terminal positioning block 12. The right side of the terminal positioning block 12 extends out of the inner cavity 31 from the opening 32, so as to be convenient for the user to start and facilitate the user to embed or take out the terminal positioning block 12 from the inner cavity 31.

[0027] Preferably, the terminal 40 is L-shaped, the terminal fixing groove 121 is located on one side of the welding window 122.

When welding is required, the first arm is inserted into the terminal fixing groove 121, and the second arm horizontally extends from the bottom end of the first arm along the bottom of the terminal positioning block 12 to the bottom end of the welding window 122. The welding window 122 exposes the second arm of the component below the floating electrode 23, and the second welding point 41 is located on the part of the second arm in the welding window 122;

[0028] Specifically, the housing positioning member 11 includes a housing positioning block 111 and a base 113. The positioning groove 112 is formed in the housing positioning block 111. The housing positioning block 111 is fixed on the upper surface of the base 113, and the base 113 is placed on the welding workbench 21 to adjust the position of the housing positioning block 111 by moving the base 113;

[0029] Specifically, the base 113 is provided with a moving space 114. The moving space 114 is located below the positioning groove 112 and is communicated with the positioning groove 112. The moving space 114 is for the fixing electrode 24 to be placed below the positioning groove 112. When the housing 30 is placed in the positioning groove 112, the fixing electrode 24 abuts against the lower surface of the lower end of the housing 30;
