[0019] As Figure 1 shown in a kind of transfer gripper mounting hole positioning mechanism, including transfer gripper 1, the gripper body 11 is installed on the transfer gripper 1, the mounting hole 12 is provided on the gripper body 11, positioning mechanism 3 is installed on the side of the transfer gripper 1;

[0020] The transfer gripper 1 is prior art, not much more detailed description here, the positioning mechanism 3 is to accurately position the mounting hole 12 on the gripper body 11 on the transfer gripper 1 when installing, so that the gripper body 11 is more accurate and quickly preliminary positioning on the transfer gripper 1, then the operator installs it with bolt;

[0021] As Figure 2 shown, positioning mechanism 3 includes base 31, the limit plate 32 is installed on the base 31, the center of the inner side of the limit plate 32 is installed with the middle plate 33, the spring 35 is provided on both sides of the middle plate 33, the threaded rod 34 is installed in the spring 35, the threaded rod 34 is rotatably connected with the middle plate 33, the threaded rod 34 is rotatably connected with the limit plate 32 at both ends, the connecting frame 37 is threadedly connected at both ends of the threaded rod 34, the connecting frame 37 is slidably connected with the limit plate 32, the moving frame 38 is rotatably connected at the top end of the connecting frame 37, the positioning frame 39 is installed at the center of the moving frame 38;

[0022] The limit plate 32 is fixedly connected with the base 31 and does not move, wherein a straight slot (not marked in the figure) is provided, the connecting frame 37 slides in the straight slot, when the mechanism moves, the rotation of the threaded rod 34 can drive the threaded connecting frame 37 to move linearly along the direction defined by the straight slot, the movement mode is to approach or move away from the middle plate 33, the positioning frame 39 rotatably connected with the connecting frame 37 can be adjusted and positioned according to the type of the transfer gripper 1 to be positioned, and the positioning frame 39 can be inserted into the bolt hole;

[0023] The threaded rod 34 is a double-end screw, the helical directions on both sides of the middle plate 33 are opposite, so that when the threaded rod 34 rotates, the connecting frames 37 installed at both ends relatively move, and the movement distances of the two connecting frames 37 are the same;

[0024] The threaded rod 34 is installed with a crank 36 at the tail end, the crank 36 is provided as a driving mode to control the movement of the whole mechanism, when in use, the operator drives the threaded rod 34 to rotate by rotating the crank 36, so as to drive the connecting frame 37 to approach or move away from the middle plate 33;
