Description

TECHNICAL FIELD

[0001] The utility model relates to the field of automation, especially a tool positioning device and transfer mechanism. BACKGROUND

[0002] In the automatic production, the workpiece is often transferred from the initial position fixed in one tray to the target position fixed in another tray by a tool such as a clamp. Since the cost of the automatic production line is high, and the products are updated, the same automatic production line is used for the production of different products, which leads to the change of the initial position and the target position after the change of the work content of the production line.

[0003] At present, the position adjustment and correction are often carried out by adjusting the stroke of the servo motor. However, the cost of the stroke-adjustable servo motor is obviously higher than that of the stroke-fixed motor and cylinder, and it is difficult to adjust the initial position and the target position by the motor control only, which needs to be corrected repeatedly and has poor practicability.
