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
The present invention relates to motor, be specifically related to be used to process the device of excircle of thin-walled workpiece of motor.
Background technology
In the machining of motor component, thin-wall workpiece is more unmanageable a kind of.The thin-wall workpiece work in-process problem of easy appearance is distortion, and distortion is size distortion and the excessive compressive deformation that is heated that causes of the depth of cut that causes because of the chuck location.Simultaneously, the precision of thin-wall workpiece and Geometrical Tolerance Principle are also higher than the processing request of general workpiece.In traditional design of electrical motor, the method that improves the excircle of thin-walled workpiece crudy is to stay bigger turning allowance, but this method is in waste material, and machining accuracy also is difficult to guarantee, and makes the thin-wall workpiece distortion easily.
The content of invention
At the problems referred to above in the existing excircle of thin-walled workpiece of motor processing, the applicant improves through research, and a kind of processing unit (plant) of excircle of thin-walled workpiece of motor is provided, and can guarantee the concentricity of thin-wall workpiece processing, and effectively avoids the radial deformation of thin-wall workpiece.
Technical scheme of the present invention is as follows:
A kind of processing unit (plant) of excircle of thin-walled workpiece of motor, comprise scroll chuck, scroll chuck is connected with an end of mandrel, and the other end of mandrel is provided with the positioning step of thin-wall workpiece to be processed, and described positioning step connects the location cover plate of thin-wall workpiece to be processed by lock-screw.
Its further technical scheme is: the exradius of described mandrel is less than the exradius of thin-wall workpiece.
Its further technical scheme is: the height of described positioning step is identical with the height of thin-wall workpiece.
Its further technical scheme is: a side of described location cover plate has the annular end head.
Its further technical scheme is: the exradius of described location cover plate is less than the exradius of thin-wall workpiece.
Useful technique effect of the present invention is:
As benchmark, thin-wall workpiece is respectively by the positioning step of mandrel and cover plate location, location with the positioning step of mandrel in the present invention, and with lock-screw locking, make thin-wall workpiece in the course of processing in the radial and axial location that all obtains, to guarantee the concentricity of processing.The present invention is simple in structure, compact, and the auxiliary mould of employing belt carcass axle is located the inside and outside circle thin-wall workpiece and processed, effectively avoid producing the workpiece radial deformation because of thin-wall workpiece is subjected to the chuck clamping force, and to the almost not influence of thin-wall workpiece mechanical property.
Description of drawings
Fig. 1 is a structural representation of the present invention.

Fig. 3 is the left view of Fig. 2.
Embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described further.
Fig. 1 shows structure of the present invention, and the thin-wall workpiece 3 among the figure does not belong to parts of the present invention.As shown in Figure 1, the processing unit (plant) of excircle of thin-walled workpiece of motor comprises scroll chuck 1, and present embodiment adopts soft scroll chuck.Scroll chuck 1 is connected with an end of mandrel 2, and the other end of mandrel 2 is provided with positioning step 6, and thin-wall workpiece 3 to be processed is set on the positioning step 6 of mandrel 2, and the exradius of mandrel 2 is less than the exradius of thin-wall workpiece 3, and present embodiment is little 0.01mm.Be processed with annular end head 7 on the cover plate 4 of location and be used to withstand thin-wall workpiece 3, the exradius of location cover plate 4 is less than the exradius of thin-wall workpiece 3, and present embodiment is little 0.25mm, and mandrel 2 is connected fastening with location cover plate 4 by lock-screw 5.
Fig. 2, Fig. 3 show the location structure of cover plate.As shown in Figure 2, location cover plate 4 is an annular end head 7 near a side of thin-wall workpiece 3, the height 2mm of annular end head 7; As shown in Figure 3, annular end head 7 exradius are than the big 1mm of its interior radius of circle, i.e. (φ A-φ B)/2=1mm.
Above-described only is preferred implementation of the present invention, the invention is not restricted to above embodiment.Be appreciated that other improvement and variation that those skilled in the art directly derive or associate under the prerequisite that does not break away from spirit of the present invention and design, all should think to be included within protection scope of the present invention.
