Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing device that can efficiently perform high-precision processing such as turning, grinding, or polishing of a product incorporating a rotating member.

Conventionally, for example, products incorporating rotating members such as floppy drive motors and VTR heads (hereinafter referred to as assembled members)
It was difficult to perform high-precision turning finishing. When the inner member and the outer member are processed separately using a general-purpose machine, a misalignment occurs between the respective machined surfaces due to gripping errors and the like, making it impossible to obtain high-precision quality. In addition, under the above-mentioned work system that requires re-gripping work, it is difficult to promote labor saving and automation, resulting in a decline in work efficiency.

In view of the above-mentioned prior art, it is an object of the present invention to provide a processing device capable of processing assembled members with high precision and high efficiency.

To achieve the above object, the present invention provides a processing device for a product incorporating a rotating member, in which an inner member and an outer member rotate on a concentric axis relative to the inner member, and an inner spindle and an outer spindle. are provided on a concentric axis, an engaging portion corresponding to the inner member is provided at the shaft end of the inner spindle, and an engaging portion corresponding to the outer member is provided at the shaft end of the outer spindle. This apparatus is characterized in that it is provided with a rotating means for sequentially rotating the inner spindle and the outer spindle.

Hereinafter, an example in which the present invention is applied to a turning machine will be described in detail.

The turning device for assembled members shown in the first eyelet body diagram is used to accurately machine assembled members that have been final assembled in order to perform high-precision C machining of floppy drive motors, VTR heads, etc. In Fig. 1, the assembled members are air chuck part 1.
The cutting tool is mounted on the carriage 3 and is turned by a cutting tool provided on the turret on the carriage 3. The rotation of the assembly members is as described below.
One spindle is driven by a drive motor 5.
The other spindle is driven via bells 1 to 7 by a drive source (not shown). The air device 9 is for driving the air chuck.

For turning machining of assembled parts (pulling control is performed by numerical control device 11')
C-Automatically, manual and other operations are performed by commanding the operating device 13 and the petal device 15'c.
- will be held.

FIG. 2 shows an enlarged sectional view of the spindle section.

The drive means for the inner spindle 17 is constituted by the drive motor 5 attached to the frame 19, and the drive means for the outer spindle 21 is illustrated as having a structure in which the pulley 23 is driven from a drive source (not shown) via the bells 1 to 7. An extended inner spindle 25 extends from the shaft tip of the inner spindle 17, and an engaging portion 27 is provided that corresponds to the inner portion UWi of the assembled portion tlAW 3-. The engaging portion 27 inserts the C pin 31 into the hole of the inner member Wi through the spring 29.
It is attached to the extended inner spindle 25 via 33 to the inner spindle 25. On the other hand, an engaging portion 3 is provided at the shaft end of the outer spindle 21.
5 and C. The engaging part 35 consists of an air chuck 37 and an engaging claw 39, and grips the reference surface 41 of the outer part (A) of the assembled member.

In the above configuration, the air chuck 37 is gripped with the reference surface 41 of the outer part +3 W o by the actuating ripple engaging claw 39, and the inner member W1 is engaged with the pin 31 of the engaging part 27 to perform turning processing. Fixing the inner spindle 17, i.e. pin 31
If the inner and outer members W1 are fixed and the outer spindle 21 is rotated, the outer member can be rotated. Machining surface 43 of this outer member
If turning is performed by applying a predetermined pie 1- to the surface, C-turning can be performed with the Z-axis, which is the axis of the spindle, as the axis. Next, when the outer spindle 21 is fixed and the inner spindle 17 is rotated, the inner member is rotated by the rotation of the pin 31. By applying a predetermined cutting tool to the machining surface 4-45 of the inner member Wi, precise turning machining centered around the Z-axis can be performed as described above. Of course, in the turning process, the rotation of the outer spindle, the rotation of the inner spindle, the movement of the carriage, etc. can all be performed automatically by a numerical control device.

FIG. 3 shows another embodiment of the inner engaging portion. Inner member W
The engaging surface of i is engaged with correls 1 to 47 having grooves. Cholera] ~ 47 has an inclined surface on its inner surface, so it can accommodate several types of inner menstruation, and together with the strain absorption ability of the grooves, the inner surface tJW
A slight axis rotation of i can be absorbed. Further, a spring 49 is connected between the collet 47 and the inner spindle 17.
Since a gap is formed between the joint bolt 51 and the joint bolt 51 to allow sliding in the Z-axis direction, installation errors and
Can absorb dimensional errors, vibrations during processing, etc.

FIG. 4 shows an embodiment in which the collet engaging portion shown in FIG. 3 is further improved. The engaging portion of the inner member in FIG. 4 is similar to the one shown in FIG.
~4F and spring 49 are unit (~1 to form spring unit 1-53. Spring unit 1-53 can move 1 to cholera 1 to 47 to middle part 55) The intermediate part assembly 55 is connected to the inner spindle 1 by connecting ports 1 to 57 so that
It is fixed at 7. Therefore, the user 1-53 incorporating the spring 49 can be easily attached and detached by operating the ports 1-57. By configuring the spring unit 53 to be compatible with various assembled members, it becomes possible to correspond to a wide range of assembled members and perform quick replacement work.

As understood from the description of the above embodiments, this invention
The inner spindle and outer spindle are arranged on a concentric axis (
C) an engaging part corresponding to the inner member is provided at the shaft end of the inner spindle, and an engaging part corresponding to and covering the outer member is provided at the shaft end of the outer spindle; Since the present invention is characterized by the provision of a rotating means for sequentially rotating the spindle, the assembled members can be applied with high precision and high efficiency. It's too much to do.
