Abstract

The invention relates to a multipurpose conical surface locking clamp. The multipurpose conical surface locking clamp comprises a clamp body, a replaceable cushion block, a conical locking sleeve, a spring, a thrust bearing, a threaded locking block, a cylindrical positioning block and a special hinge lever, the clamp body is composed of a quartering clamping head and a clamping column, the replaceable cushion block is composed of four equal blocks, the four equal blocks can define a circular ring, the side wall of the upper portion of an inner hole of the conical locking sleeve is an inner conical face matched with the conical face of the outer side wall of the quartering clamping head of the clamp body, the threaded locking block is in a circular ring shape, the inner hole is provided with locking inner threads, and the outer side wall is provided with a reaming lever positioning hole; and the cylindrical positioning block is a step cylinder, a concave hole is formed in the center of the top end of the cylindrical positioning block, the wall of the concave hole is a conical positioning face, and a plane positioning face surrounds the concave hole. The multipurpose conical surface locking clamp has the advantages that positioning and clamping are convenient when a specific structural part is turned and milled, machining of a plurality of working procedures such as turning and milling can be completed through one clamp, and the production efficiency can be greatly improved while the machining precision can be guaranteed.

Description

technical field [0001] The invention relates to a multipurpose conical surface locking fixture, which belongs to the technical field of machining locking fixtures. Background technique [0002] In the machining process, special fixtures are often designed to improve the clamping efficiency, positioning efficiency and processing efficiency of parts. When processing square parts in large quantities, the four-jaw chuck is used for clamping and processing, which wastes more time on clamping and positioning, and limits the improvement of production efficiency. Especially for workpieces with specific shapes, it is not suitable to use a four-jaw chuck for clamping, positioning and locking. attached figure 1 , 2 A workpiece with a specific shape is given. The workpiece is composed of a cube block I with a square bottom surface, a cone II connected to a square face of the cube block I, and a spherical surface III at the top of the cone body II. There is a threaded hole IV in the ...
