Detailed Description of the Embodiment

[0018] Referring to Figure 1 and 2 , an automatic welding tooling for a hoist hopper of the present utility model includes a rotating seat I 1, a two-way rotating workbench 2, two tooling fixtures 3 and a baffle 4. The two-way rotating workbench 2 is provided on the rotating seat I 1, and the tooling fixture 3 and the baffle 4 located between the two tooling fixtures 3 are provided on the two-way rotating workbench 2.

[0019] The tooling fixture 3 includes a rotating tooling table 31, a movable end positioning assembly 32, a fixed end positioning assembly 33, and a plurality of fixed clamps 34. Both ends of the rotating tooling table 31 are rotatably connected to the bidirectional rotating worktable 2 through rotating seats II 35. The movable end positioning assembly 32 and the fixed end positioning assembly 33 are sequentially arranged on the rotating tooling table 31 in the front-rear direction. Fixed clamps 34 are arranged at both left and right edges of the rotating tooling table 31.

[0020] The fixed clamp 34 includes a fixed seat 341, a fixed cylinder 342, a rotating arm 343, a pressing seat 344, and a plurality of pressing bodies 345. The fixed seat 341 is provided with a fixed cylinder 342 and a rotating arm 343. The driving end of the fixed cylinder 342 is rotatably connected to one end of the rotating arm 343. The other end of the rotating arm 343 is provided with a pressing seat 344, and the pressing seat 344 is provided with pressing bodies 345.

[0021] The fixed seat 341 is provided with a bracket 346, and a plurality of supporting wheels 347 are arranged on the bracket 346.

[0024] The working process of the present utility model:

[0025] During the working process of the automatic welding tooling for the hopper of the elevator of the present utility model, according to the size of the hopper, first adjust the guide rod cylinder 322 to a suitable position, then place the two side plates 5 of the hopper on the positioning pins of the activity positioning plate 323 and the support I 331 respectively, then place the hopper enclosing plate 6 between the two side plates 5. The supporting wheels 347 support on the outer side of the hopper enclosing plate 6. Then, start the guide rod cylinder 322 to push the activity positioning plate 323 to move backward, clamp and fix the hopper enclosing plate 6 between the two side plates 5. Then start the fixed clamp 34 to press the corresponding end of the hopper enclosing plate 6.
