Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of positioners, and specifically relates to a positioner for a switching tooling. Background Technique
[0002] The positioner for a switching tooling is a device used for quickly replacing and positioning different toolings in an automated production line. Its main function is to ensure that the tooling can be quickly and accurately installed on the machine or production line, reduce the replacement time, improve the production efficiency and flexibility. In the scenario of multi-variety and small-batch production, quickly switching the tooling is particularly important because it can significantly reduce the non-production time of the equipment and improve the utilization rate of the equipment.
[0003] Common positioners for a switching tooling include mechanical positioners, hydraulic or pneumatic positioners, etc. These positioners usually rely on precise mechanical fitting and adjustment to achieve positioning, while hydraulic or pneumatic positioners use fluid pressure to achieve quick locking and unlocking. These positioners can achieve quick alignment through a preset zero-point system, reducing the need for manual adjustment. However, this method will cause an offset between the tooling and the positioner before tensioning because the tooling needs to be first pushed into the corresponding position of the positioner and then tightened through a hydraulic or pneumatic mechanism, thus affecting the positioning accuracy and not meeting the working requirements of the positioner. Therefore, a positioner for a switching tooling is proposed. Summary of the Invention
