In this embodiment, the driving member 60 may be a linear cylinder.
The working process of the positioning fixture 100 is approximately:
first, a worker or a gripper may place the workpiece 200 on the carrier 20;
then, the driving element 60 drives the link element 50 to move toward the direction approaching the carrier element 20, so that the rotating element 40 is driven by the link element 50 to rotate toward the workpiece 200, such that one end of the rotating element 40 rotates toward the direction approaching the link element 50 relative to the supporting portion 11, and the other end of the rotating element 40 rotates toward the direction approaching the pushing element 30 relative to the carrier element 20;
finally, the pushing member 30 moves on the carrier 20 in a direction approaching the workpiece 200 under the pushing of the other end of the rotating member 40 and pushes against the workpiece 200 to position the workpiece 200 on the carrier 20.
Therefore, the link 50 drives the rotating member 40 to rotate towards the workpiece 200, so that one end of the rotating member 40 rotates towards the direction approaching the link 50 relative to the supporting portion 11, and the other end of the rotating member 40 rotates towards the direction approaching the pushing member 30 relative to the bearing member 20, so that the pushing member 30 moves towards the workpiece 200 and pushes against the workpiece 200 under the pushing of the other end of the rotating member 40, thereby realizing the quick positioning of the workpiece 200 on the bearing member 20, and improving the positioning efficiency.
In the present embodiment, referring to fig. 1, the workpiece 200 is a rectangular frame structure, and includes four frames opposite to each other in pairs, referring to fig. 2, the positioning fixture 100 includes four pushing members 30 and four rotating members 40, and four supporting portions 11 are disposed on the base 10.

The operation of the rotating member 40 is substantially:
firstly, the link member 50 is driven by the driving member 60 to move toward the carrier member 20, so that the link member 50 drives the rotating member 40 to rotate toward the workpiece 200 through the second rotating shaft 44;
then, the first rotating portion 41 drives the first rotating shaft 43 to move along the direction opposite to the pushing direction of the pushing member 30, so that the first rotating shaft 43 abuts against the supporting portion 11, and the first rotating portion 41 rotates toward the direction approaching the supporting member 20, and meanwhile, the second rotating portion 42 drives the third rotating shaft 45 to abut against the pushing member 30, and the second rotating portion 42 rotates toward the direction approaching the workpiece 200;
finally, the link 50 continues to move toward the direction approaching the carrier 20, so that the rotating member 40 rotates toward the workpiece 200 by the first rotating shaft 43 and the link 50, and the second rotating portion 42 pushes the pushing member 30 to move toward the workpiece 200 by the third rotating shaft 45, so that the pushing member 30 pushes the workpiece 200 by the second rotating portion 42, so as to position the workpiece 200 on the carrier 20.
Therefore, one end of the first rotating portion 41 is movably connected to the supporting portion 11 through the first rotating shaft 43, and the other end of the first rotating portion 41 is rotatably connected to the linking member 50 through the second rotating shaft 44, so that the rotating member 40 is abutted to the supporting portion 11 through the first rotating shaft 43 under the driving of the linking member 50, and the rotating member 40 rotates towards the workpiece 200 with the first rotating shaft 43 as a rotating shaft, so that the second rotating portion 42 stably pushes the abutting member 30 to move towards the workpiece 200 through the third rotating shaft 45, and further the abutting member 30 stably positions the workpiece 200 to the bearing member 20, thereby improving the positioning efficiency.
