Machining rocker arm type clamp device

Abstract

The invention discloses a machining rocker arm type clamp device. The machining rocker arm type clamp device comprises a shell, a lock buckle, a self-locking mechanism with tap positions, a drive rod and bevel gears; a screw rod is connected to the lower end of the drive rod; the bevel gears comprise the first bevel gear and the second bevel gear, an internal thread matched with the screw rod is arranged inside the first bevel gear, the second bevel gear and the first bevel gear are matched with each other and form a certain angle, and a rocking handle is inserted into an inner hole of the second bevel gear. The machining stepping type clamp device has the dual self-locking function, the locking performance is good, the structural design is ingenious, operation is easy, the machining accuracy of work-pieces is guaranteed, the production quality of the work-pieces is improved, and the production safety is guaranteed.

Description

technical field [0001] The invention relates to the field of machining fixtures, in particular to a machining rocker-arm type fixture device. Background technique [0002] At present, in the field of mechanical processing of gems and crystals, it is necessary to lock the gems and crystals to be processed through the clamp locking device. Therefore, the clamping performance of the clamp locking device is very important. However, when the size of the workpiece to be processed changes, the insufficient clamping force of the fixture will cause the workpiece to be in a loose or semi-loose state, which will affect the machining accuracy of the workpiece and cause a series of production safety problems. [0003] In short, there are two main problems in the current workpiece fixture locking device: first, a single self-locking cannot guarantee the clamping performance of the fixture; second, when the size of the workpiece to be processed has a large difference, the clamping force of...
