Centrifugal clamping device

Abstract

The invention discloses a centrifugal clamping device, which comprises a centrifugal device, wherein the centrifugal device comprises a rotary disk for generating a centrifugal force, a plurality of centrifugal blocks, a resetting device and a clamping device, wherein the centrifugal blocks are uniformly distributed on the same axial end surface of the rotary disk; one end of each centrifugal block is circumferentially fixed with a rotating shaft which is in sliding fit with the interior of an axial hole of the rotary disk; the other end of each centrifugal block is a free end and the centrifugal blocks are also connected with the resetting device; the clamping device comprises a supporting disk, a supporting rod and a centering and clamping part; a cavity for accommodating the rotary disk is arranged on one axial end surface of the supporting disk; the rotary disk can be rotatably matched with the interior of the cavity; the other end of the rotating shaft connected with the centrifugal blocks penetrates through the supporting disk, reaches the other axial end surface of the supporting disk and then is fixedly connected with one end of the supporting rod; and the centering and clamping part is fixedly arranged at the other end of the supporting rod. The centrifugal clamping device has the advantage of bringing convenience for clamping and positioning of bars.

Description

technical field [0001] The invention relates to a tooling in the technical field of machine tool processing, in particular to a centrifugal clamping device for clamping and positioning bars. Background technique [0002] In the field of mechanical processing, when the bar is turned or drilled, due to the poor clamping and positioning of the bar, the bar is easy to shake during the processing, which leads to the out-of-round processing surface or the concentricity of the drilled inner hole. Poor, visual inspection, there is no effective fixture to solve this ubiquitous problem. However, when the existing tooling fixture is used to process long bars with deep holes, the clamped part is often the end of the hole, which leads to excessive clamping pressure when the clamp is clamped, and excessive clamping pressure will often cause deep holes. The hole is deformed, resulting in waste products, and the clamping pressure is small and closes, causing the bar to fly out during the p...

[0002] In the field of mechanical processing, when the bar is turned or drilled, due to the poor clamping and positioning of the bar, the bar is easy to shake during the processing, which leads to the out-of-round processing surface or the concentricity of the drilled inner hole. Poor, visual inspection, there is no effective fixture to solve this common problem

However, when the existing tooling fixture is used to process long bars with deep holes, the clamped part is often the end of the hole, which leads to excessive clamping pressure when the clamp is clamped, and excessive clamping pressure will often cause deep holes. The hole is deformed, resulting in waste products, and the clamping pressure is small and closes, causing the bar to fly out during the processing, resulting in a safety accident
