Anti-vibration core expanding tool with locking function

Abstract

The invention discloses an anti-vibration core expanding tool with a locking function. The anti-vibration core expanding tool comprises a tool bottom plate, a guide rail mechanism and core expanding movable blocks. The guide rail mechanism is arranged on the tool bottom plate. The core expanding movable blocks are arranged in the guide rail mechanism. An expanding sleeve mechanism is arranged between the tool bottom plate and the core expanding movable blocks. An anti-vibration mechanism with the locking function is further arranged between every two adjacent core expanding movable blocks and the tool bottom plate. By the adoption of the anti-vibration core expanding tool, the problem that in the high-speed running process, due to uneven stress, vibration and deformation are generated, and consequently the deformation amounts of different positions are different can be effectively solved, expanding force applied to the inner side wall of a workpiece to be machined is even, and the anti-vibration core expanding tool has the beneficial effects of being simple in structure, low in production cost, convenient to operate, high in shaping speed, high in practicability and suitable for application and popularization.

Description

technical field [0001] The invention relates to the technical field of mechanical processing, in particular to an anti-seismic expansion core tooling with a locking function. Background technique [0002] As a machining industry, a variety of disc workpieces are often encountered. In the machining process of the workpiece, after the inner hole of the workpiece is processed, the outer circle of the workpiece often needs to be processed. When processing the outer circle of the workpiece, it is necessary to ensure that the outer circle to be processed is concentric with the inner hole of the workpiece. In order to improve processing efficiency, reduce the number of clamping times and clamping time, and because of the special requirements that some workpieces do not allow the end face to be pressed, the inner hole processing can only be completed after tightening and fixing. Therefore, we often design and manufacture a kind of expansion sleeve and core tooling that is position...

Problems solved by technology

[0004] The technical problem to be solved by the present invention is to provide a core-expanding tool with simple structure, convenient operation, and fast setting speed in view of the problems existing in the background technology. Using the core-expanding tool can effectively avoid the problem caused by insufficient force during high-speed operation. Even, vibration and deformation are generated, resulting in different deformations at different positions, thereby improving the processing quality. Specifically, it is an anti-seismic expansion core tooling with a locking function.
