Machining clamp for work piece having taper hole and used in numerically-controlled machine tool

Abstract

The invention relates to a machining clamp for a work piece having taper holes and used in a numerically-controlled machine tool. The machining clamp includes a clamp body, a clamping shaft and a stripping device; one of the clamp body is provided with a connection section which is connected to a main shaft of the numerically-controlled machine tool, and the other end of the clamp body is provided with a connection hole which is coaxial with the main shaft; one end of the clamping shaft is fixedly arranged in the connection hole, and the other end of the clamping shaft is provided with a self-locking taper surface fitting the taper hole of the work piece; the stripping device includes an air cylinder, a stripping plate, a push rod, a stressed block, and a reset spring; a slide groove is formed in the clamp body, and the stressed block is slidingly arranged in the slide groove; an end surface provided with the clamping shaft, of the clamp body is provided with a slide hole which communicates with the slide groove, wherein the push rod can pass through the slide hole; the stripping device slidingly sleeves the clamping shaft and is connected to the stressed block through the push rod; a push shaft of the air cylinder acts on the stressed block; the push rod is sleeved with the reset spring; and the reset spring is positioned between the stressed block and the bottom of the slide groove. The machining clamp is high in positioning accuracy, can conveniently clamp and strip the work piece, and can effectively improve the production efficiency.

Description

technical field [0001] The invention relates to a tool for a numerically controlled machine tool, in particular to a processing fixture for a workpiece with a tapered hole on a numerically controlled machine tool. Background technique [0002] When processing the outer surface of some workpieces with tapered holes, in order to ensure the processing quality, it is often necessary to ensure the coaxiality of the clamping. If a traditional three-jaw or four-jaw chuck is used for clamping, it is not only inconvenient to clamp, but also very time-consuming and laborious to measure the coaxiality after clamping. Therefore, when processing such workpieces, the inner hole can be positioned and clamped, and the coaxiality can be well guaranteed. Although positioning and clamping the inner hole can ensure the clamping effect, it is inconvenient to clamp and unload parts, and it cannot effectively improve production efficiency.
