Embodiment Construction

[0015] The specific embodiments of the present invention will be further described below in conjunction with the drawings.

[0016] figure 1 The structure of the present invention is shown, and the thin-walled workpiece 3 in the figure is not a part of the present invention. Such as figure 1 As shown, the machining device for the outer circle of the thin-walled workpiece of the motor includes a three-jaw chuck 1. This embodiment uses a soft three-jaw chuck. The three-jaw chuck 1 is connected to one end of the mandrel 2. The other end of the mandrel 2 is provided with a positioning step 6. The thin-walled workpiece 3 to be processed is sleeved on the positioning step 6 of the mandrel 2. The outer radius of the mandrel 2 It is smaller than the outer radius of the thin-walled workpiece 3, which is smaller than 0.01 mm in this embodiment. The positioning cover 4 is machined with an annular end head 7 for supporting the thin-walled workpiece 3. The outer radius of the positioning cov...

Abstract

The invention relates to a machining device of an excircle of a thin-walled workpiece of a motor, which comprises a three-jaw chuck, wherein the three-jaw chuck is connected with one end of a central spindle, the other end of the central spindle is provided with a positioning step of a thin-walled workpiece to be machined, and the positioning step is connected with a positioning cover plate of the thin-walled workpiece to be machined through a locking bolt. By using the positioning step of the central spindle as a reference, the thin-walled workpiece is respectively positioned by the positioning step and the positioning cover plate of the central spindle and is locked by the locking bolt to enable the thin-walled workpiece to be positioned at the radial direction and the axial direction during the machining so as to ensure the machining concentricity. The invention has simple and compact structure; and the incircle and the excircle of the thin-walled workpiece are positioned and machined by adopting an auxiliary tool with the central spindle, thereby effectively avoiding the workpiece radial deformation caused by the chuck clamping force and causing no influence on the mechanical property of the thin-walled workpiece.

Description

Technical field [0001] The invention relates to a motor, in particular to a device for processing the outer circle of a thin-walled workpiece of the motor. Background technique [0002] In the machining of motor parts, thin-walled workpieces are one of the more difficult to machine. The most prone problem in the processing of thin-walled workpieces is deformation. The deformation is due to the dimensional deformation caused by the positioning of the chuck and the deformation caused by the heat and pressure caused by the excessive feed amount. At the same time, the precision and shape tolerance requirements of thin-walled workpieces are also higher than those of ordinary workpieces. In traditional motor design, the method to improve the external machining quality of thin-walled workpieces is to leave a larger turning margin. However, this method wastes materials, while machining accuracy is difficult to guarantee, and it is easy to deform thin-walled workpieces. Content of the i...
