Rotor core shaft milling tooth fixture

Abstract

The invention discloses a rotor core shaft milling tooth fixture. The rotor core shaft milling tooth fixture is characterized in that the rotor core shaft milling tooth fixture comprises a fixing sleeve and a clamping sleeve, wherein a through hole is formed in the fixing sleeve, and a bell mouth communicating with the through hole is formed in one side of the fixing sleeve in the length direction; a first step is arranged on an outer edge protrusion in the radial direction of the fixing sleeve close to the bell mouth, the shape of the bell mouth of the fixing sleeve is matched with one side of the clamping sleeve in the length direction, a long groove is formed in the side of the clamping sleeve along an outer edge, and a second step is arranged in the clamping sleeve on the side; and theside, in the length direction, of the clamping sleeve penetrates through the through hole in the fixing sleeve, and the end part of the other side, in the length direction, of the clamping sleeve islocated on the exterior of end surface of the other side, in the length direction, of the fixing sleeve. After the structure is adopted, before the rotor core shaft milling tooth fixture is used, theclamping sleeves with different specifications are prepared according to motor rotor shaft with different lengths. The fixture is installed on a milling machine, a fixing sleeve is installed on a mainshaft of the milling machine, a pull rod drives the clamping sleeve to be in rectilinear motion to clamping a workpiece, the clamping accuracy is ensured, and large quantities of products can be processed conveniently.

Description

technical field [0001] The invention relates to a gear milling fixture for a rotor core shaft. Background technique [0002] The slender rotor mandrel requires the use of fixtures during tooth milling and cutting. Existing fixtures such as figure 1 As shown: a clamping hole is set in the center, one end has a Morse taper, and the other end is radially set with a limit hole. When the existing rotor mandrel is processed by a jig, manually use a jackscrew to pass through the limit. Clamping is achieved behind the hole. This method is easy to slip, easily injures the operator and has low work efficiency. For the processing of relatively slender rotor mandrels, it is difficult to ensure the clamping accuracy, and it is difficult to maintain the stability and accuracy consistency of mass production.
