Cylindrical grinder three-jaw poking fixture

Abstract

The invention relates to a cylindrical grinder three-jaw poking fixture, including a Mohs principle shaft, a rotating body sleeving the right end of the Mohs principle shaft and a self-centering chuck fixedly connected to the rotating body, wherein a plurality of conical roller bearings sleeving the Mohs principle shaft are arranged in the rotating body, inner check rings and outer check rings are arranged among the conical roller bearings, a check ring for limiting the conical roller bearings is fixedly arranged at the right end of the Mohs principle shaft, a dust cover is fixedly connected to the left end of the rotating body, the inner wall of the dust cover is provided with an oil seal, and a poking rod is arranged on the rotating body; by adopting the above structure, a workpiece can be driven to rotate by poking the poking rod, thus being convenient and simple to operate, reducing wearing of the cylindrical grinder due to the poking plate mechanism, and increasing the workpiece grinding precision of the three jaws.

Description

technical field [0001] The invention relates to a tooling, in particular to a three-jaw tooling for an external grinder. Background technique [0002] The top of the main shaft of the external energy circular grinder and the dial make two sets of mechanisms. Generally, the top does not rotate when grinding the outer circle, and the workpiece is rotated by the lever to rotate the workpiece. When grinding the inner hole of the workpiece with a self-centering chuck, it needs to be simultaneously Turning can only be processed. When producing cemented carbide tools, some workpieces need to be clamped by a self-centering chuck at one end, and the other end should be supported by the tip for processing. Contents of the invention [0003] The object of the present invention is to provide a three-claw toggle tool for a cylindrical grinder with simple and reasonable structure and convenient operation. [0004] The technical scheme that realizes the object of the present invention i...

[0002] The top of the main shaft and the dial of the external energy circular grinder use two sets of mechanisms. Generally, the top does not rotate when grinding the outer circle, and the workpiece is rotated by the lever to rotate the workpiece. When using a self-centering chuck to grind the inner hole of the workpiece, it needs to be Turning can only be processed. When producing cemented carbide tools, some workpieces need to be clamped by a self-centering chuck at one end, and the other end should be held by the tip for processing. When the tip is used to tighten the workpiece, the head is easy to lock.
