Abstract
The utility model discloses a hollow shaft positioning tool. The hollow shaft positioning tool comprises a central shaft provided with a positioning rod at one end, wherein two ends of the central shaft penetrate through a first positioning block and a second positioning block, a hollow shaft is sleeved on the central shaft and is fixed through the positioning blocks and a positioning nut, and then the central shaft is fixed on a machine tool through the positioning rod to be machined, and machining efficiency is improved.
Description
Technical field
The utility model relates to a kind of hollow shaft processing component, and concrete is a kind of hollow shaft positioning tool.
Background technology
Often need the hollow axial workpiece of processing in machine-building, the demanding hollow axial workpiece work in-process of dimensional accuracy and roughness need pass through milling, grinding and just can finish.Because the general wall thickness dimension of hollow axial workpiece is less, the clamping difficulty, and deform easily.In order to guarantee to process the part that adheres to specification, often to design and a kind of hollow axial workpiece is fixed on positioning tool on the grinding machine centre of location hole.
The utility model content
The utility model proposes a kind of hollow shaft positioning tool, make hollow shaft fixed-site in process.
The technical solution of the utility model is achieved in that a kind of hollow shaft positioning tool, comprises that an end is provided with the central shaft of backstay, and described central shaft two ends are passed first locating piece and second locating piece respectively.
Further, described first locating piece and second locating piece are hollow cylinder.
Further, described first locating piece and second locating piece are 30 ° of chamferings near the face at central shaft middle part.
Further, described first locating piece and second locating piece are the conical surface near the face at central shaft middle part.
Further, the described central shaft other end setscrew nut that has been threaded.
Further, described setscrew nut and second locating piece are connected.
The beneficial effects of the utility model are: hollow shaft sleeve on central shaft, is fixed by locating piece and setscrew nut, then central shaft is fixed on the lathe by backstay, process, working (machining) efficiency is provided.
