Abstract

The invention discloses an internal clamping device which comprises a force application device arranged inside a shell body, a force transmission device and a holding device. The force application device is a sliding body of a jacking work piece. A transmission pin and a clamping pin are arranged in the sliding body and are vertical to each other and contacted with each other in an inclined mode. A compression spring is arranged at the bottom of the transmission pin. A reset spring is arranged at the bottom of the sliding body. The work piece is arranged on the sliding body, the sliding body moves downwards under action of self gravity of the work piece, the transmission pin tightly presses the clamping pin under action of the compression spring at the bottom, the clamping pin is jacked out of the clamping work piece, and therefore location through the sliding body and clamping through the clamping pin are achieved.

Description

technical field [0001] The invention relates to a machining fixture, in particular to an internal clamping device. Background technique [0002] During processing, the workpiece needs to be accurately positioned before clamping. After the processing is completed, first loosen the clamping device, and then loosen the clamping device. The current clamping device adopts a distributed clamping method for positioning and clamping. Two sets of systems are used for positioning and clamping. This design is more precise. But when efficiency is required for processing, such a device with complex structure and low clamping efficiency cannot meet the needs. Contents of the invention [0003] The purpose of the present invention is to provide an internal clamping tool with simple structure, which can realize positioning and clamping through a set of force transmission system. [0004] In order to achieve the above object, the technical solution of the present invention is: the intern...
