Multi-station positioning locking mechanism

Abstract

The invention discloses a multi-station positioning locking mechanism, comprising a locking hole supporting seat, a positioning hole supporting seat, a rotating shaft, a locking bracket, a locking wrench, a rotating block, a spring and a steel ball, wherein the locking bracket is fixed at one end of the rotating shaft; the locking wrench is supported at the other end of the rotating shaft in a hinge manner; the rotating block is fixed on the rotating shaft; the spring and the steel ball are arranged on the rotating block. A threaded hole is formed in the rotating block, and is used for fixing other structures. The rotating block has two states; the first state is that the rotating block rotates along with the rotating shaft so as to perform multi-station change; the second state is that the rotating block is locked along with the rotating shaft. The alternation of the two states of the rotating block can be realized through the matching effect between the locking wrench and the locking bracket. The spring and the steel ball, which are arranged on the rotating block, are matched with the positioning groove in the positioning hole supporting seat, so that the positioning function is realized. The multi-station positioning locking mechanism has the advantages that the structure is relatively simple, the operation is convenient, and the operation of accurately positioning and locking multiple stations can be effectively and quickly performed.

Description

technical field [0001] The invention belongs to the field of mechanical structure and mechanical design, and in particular relates to a multi-station positioning and locking mechanism. Background technique [0002] Positioning and locking mechanisms are commonly used in robotics and other fields, and are used to achieve rapid positioning and locking. An existing fast positioning locking mechanism includes a lock sleeve with a bottom cover at one end, a pin shaft that can slide axially in the inner cavity of the lock sleeve, and is arranged at the bottom end of the inner cavity of the lock sleeve to conflict with the left end of the pin shaft. The compression spring; on the right side of the end where the pin shaft and the compression spring abut, there is a conical surface that shrinks to the right, and an axial guide groove that runs through its diameter is opened on the pin shaft on the right side of the conical surface. A position-limiting guide column that can slide axi...

Problems solved by technology

However, this device cannot realize the multi-position positioning and locking function. Since each structure is discrete and a single limit guide column is used, multiple operations are required in each positioning process. It is not as simple as the integrated one, and it is difficult to use. in highly automated equipment

Moreover, the device does not have a device connected to external equipment, so that its use range is narrow and its integration with other devices is poor.
