[0018] The following combines the drawings and embodiments to further illustrate the technical solutions of the present utility model:

[0019] Refer to Figure 1-6 As shown, the present utility model provides a positioning spot welding tooling for the conduction sheet of a heater, including: a cylinder 1, a plurality of positioning strips 2 are uniformly welded on the peripheral side of the cylinder 1, a positioning plate 3 is welded at the bottom end of the cylinder 1, a mounting seat 4 is arranged at the bottom end of the positioning plate 3, and a bottom plate 5 is welded at the bottom end of the mounting seat 4. The radius of the positioning plate 3 is greater than the sum of the radius of the cylinder 1 and the length of the positioning strip 2. The bottom end is positioned by the positioning plate 3 to ensure that the bottom of the conduction sheet 6 is flat.

[0020] As a preferred embodiment, the number of the positioning strips 2 is 25.

[0021] As a preferred embodiment, the height of the tooling is 242 mm, and the height of the mounting seat 4 is 56 mm.

[0022] The working process and principle of the present utility model are:

[0023] Vertically place the tooling on the workbench, evenly insert the conduction sheet 6 onto the positioning strips 2. The number of the positioning strips 2 is 25 to ensure that the quantity is correct. The height is positioned by the bottom plate 5 to ensure that the bottom is flat; then install the inner sleeve 7, and finally pick up the tooling and perform spot welding at the front for positioning. After all spot welding is completed, take out the tooling, and then perform spot welding on the rear end of the conduction sheet 6 to ensure that both ends are completely spot welded and positioned, and then enter the next process.

[0024] In the description of the present application, it should be noted that the orientation or positional relationship indicated by terms such as "upper" and "lower" is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present application. Unless otherwise clearly specified and defined, the terms "mounted", "connected" and "coupled" shall be construed in a broad sense. For example, it may be a fixed connection, a detachable connection or an integral connection; it may be a mechanical connection or an electrical connection; it may be directly connected or indirectly connected through an intermediate medium, and it may be the communication inside two elements.
