The following embodiments are used to illustrate the present invention but not to limit the scope of the present invention.
[0023] See the attached Figure 1-6 As shown in the figure, the welding fixture for the air conditioner outer casing in the first embodiment includes: an operating table 1; a tooling table rotatably provided on the operating table 1 for placing and positioning the air conditioner outer casing.
[0024] The tooling table includes: a placing plate 2; a plurality of positioning grooves 21 opened on the placing plate 2; and a through hole 22 penetrating through the middle of the placing plate 2, and the plurality of positioning grooves 21 are evenly spaced in a ring around the through hole 22; an adjustable bracket fixedly provided on the operating table 1 for mounting welding equipment; and a support mechanism mounted on the operating table 1 for supporting the tooling table and realizing its rotation.
[0025] The air conditioner outer casing can be placed on the placing plate 2, and then the positioning pins or locating pins are inserted into the positioning grooves 21 and the through hole 22 by passing through the holes on the air conditioner outer casing. When two positioning pins are inserted into the positioning grooves 21 and one positioning pin is inserted into the through hole 22, due to the annular interval distribution of the positioning grooves 21, triangular positioning of the air conditioner casing can be realized, which is simple and convenient to operate and improves work efficiency. Since the positioning grooves 21 have a certain length, the positioning pins can adjust their positions according to the length of the positioning grooves on the air conditioner outer casing to adapt to various sizes and shapes of air conditioner outer casings, improving practicability and reducing tooling costs.
[0026] The welding equipment can be fixed by the adjustable bracket, and the welding position can be adjusted by using the adjustable bracket. The support mechanism can support the tooling table and enable the rotation of the tooling table, facilitating the adjustment of the welding position.
[0027] Furthermore, the adjustable bracket includes: a vertical linear guide rail 3 vertically arranged on the operating table 1; a first driving member 31 that vertically reciprocates through the vertical linear rail; a transverse linear guide rail 32 transversely arranged on the first driving member 31; a second driving member 33 that transversely reciprocates through the transverse linear guide rail 32; and a fixing member 34 arranged on the second driving member 33 that can fix the welding equipment.
[0028] The vertical linear guide 3 and the horizontal linear guide 32 are composed of a screw assembly and a motor, which can realize the reciprocating motion of the first driving member 31 and the second driving member 33.

The connecting column 45 is used to fix the inner ring sleeve 44 and the placement plate 2. When the inner ring bearing rotates due to the shaft rod 41, the placement plate 2 can be driven to rotate through the connecting column 45 to realize the rotation of the air conditioner casing. The positioning rod 46 can pass through the through hole 22 to expose the positioning hole, which is convenient for triangular positioning.
[0033] Furthermore, a connecting piece 47 is fixedly connected to the top end of the shaft rod 41 , and the connecting piece 47 is fixedly connected to the positioning rod 46 and the inner ring sleeve 44 , respectively.
