[0036] Furthermore, the second fixing member includes a first pressing member and a second pressing member arranged at intervals. Each of the first pressing member and the second pressing member is equipped with a second driving device. Both second driving devices are electric cylinders. The cylinder rods of the two second driving devices can extend or retract in the second direction, so that the first pressing member and the second pressing member can rise or fall relative to the fixing plate 13, thereby pressing the workpiece or releasing the workpiece in the second direction.

[0037] Furthermore, this L-type positioner also includes a first fixing member 7, which can be a rod or a plate, and is fixed to the cabinet 1.

The second rotor has a second wire harness 12, which passes through the second turntable 4 and the fixing plate 13 and is connected to the second drive device. When the bearing fixture rotates with the second rotating mechanism, the second wire harness 12 used to supply power to the second drive device will not become tangled or twisted.

[0039] Furthermore, this L-type positioner also includes a base 16, and the cabinet 1 is disposed on the base 16. Preferably, the base 16 is provided with a plurality of foot connectors 19, and the plurality of foot connectors 19 are fixed to the designated position by bolts to ensure the stability of this L-type positioner.

[0040] Furthermore, this L-type positioner also includes a bracket 17, with at least two brackets 17 arranged in parallel at intervals. One end of each bracket 17 is connected to the side panel of the cabinet 1 opposite to the first rotating mechanism, and the other end of each bracket 17 is fixed to a designated position, further enhancing the stability of this L-type positioner.

[0041] In summary, the L-type positioner provided in this application allows for adjustment of the fixed state of the workpiece to be welded by adjusting the first and second drive devices, eliminating the need for simultaneous disassembly and assembly of the workpiece and tooling. This significantly improves the convenience of workpiece disassembly, assembly, posture adjustment, and replacement operations, and reduces operational difficulty. Furthermore, by setting the first slip ring 8 and the second slip ring 10, internal wiring of the first and second drive devices can be achieved. During the operation of this L-type positioner, it is possible to prevent the wiring harnesses of the first and second drive devices from becoming tangled or twisted, thus avoiding any impact on the normal operation of the L-type positioner.
