Multipurpose quick-change positioning device with limiting function

Abstract

The invention belongs to the field of accurate positioning transmission mechanisms, and particularly relates to a multipurpose quick-change positioning device with a limiting function. The multipurpose quick-change positioning device comprises a tubular guide support and a conical mandrel sleeved with the guide support, wherein the diameter of one end of the conical mandrel is larger than that of the guide support, the other end of the conical mandrel extends out of the guide support, conical guide blocks are arranged on the outer side of the guide support, guide holes used for containing the conical guide blocks are formed in the guide support, the conical guide blocks and the conical mandrel are matched in a contact manner, the conical guide blocks are annularly and evenly distributed on the guide support, and an locking outer ring sleeves the periphery of the conical guide blocks. By the adoption of a multi-set combined structure, rapid locking and positioning can be achieved, modular assembling and disassembling can be achieved conveniently, the installation precision can be guaranteed, and interchangeable replacement can be conducted. The working efficiency is greatly improved, the multipurpose quick-change positioning device can be suitable for various working conditions, the shaft hole positioning precision is guaranteed, and meanwhile enough structural rigidity is achieved.

Description

technical field [0001] The invention belongs to the field of precise positioning transmission mechanisms, and in particular relates to a multipurpose quick-change positioning device with a limit position. Background technique [0002] In the fields of equipment and machinery, positioning and transmission are usually realized through pin shafts. Pin shafts are usually designed in various shapes and materials, and the working conditions can be divided into dynamic load and static load. It is known that the hole fit positioning device widely used is the pin shaft, which mainly controls the machining difference between the pin shaft and the shaft hole as a transition fit for hole fit positioning through machining, and is used in various industries. It belongs to the conventional device in the mechanical device and has the characteristics of reliability and stability. [0003] In the prior art, the pin shaft needs to be loaded and unloaded through auxiliary measures such as coo...
