BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a processing machine for parts having a rotating configuration, and is useful for processing, for example, disks and flyfoils of cylinders in video motors and the like.

0002

[Prior Art] Conventionally, for example, a processing method for parts with a rotating configuration includes a processing machine that fixes the outer circumference holding the shaft with a three-jaw chuck and processes the shaft by rotating it with a one-way clutch. .

0003

[Problem to be solved by the invention] In a processing machine that uses a three-jaw chuck to fix the outer circumferential portion holding the shaft and rotates the shaft using a one-way clutch for cutting, the processing machine becomes large and has a complicated configuration. .

SUMMARY OF THE INVENTION An object of the present invention is to provide a processing machine that can fabricate a member fixed to one end of a shaft or a shaft with high precision and stable quality using an easy fixing method and rotating method.

[0005]

[Means for Solving the Problems] In order to solve the above problems, the parts processing machine having a rotating configuration of the present invention supports the outer circumferential portion holding the shaft with a V-shaped fixing member, and the shaft This is a processing machine that processes a member or shaft that is rotated by an O-ring and fixed to one end of a shaft, or a shaft, with the shaft as a reference.

[0006]

[Operation] According to the present invention, the outer peripheral portion holding the shaft is supported by a V-shaped fixing member, and the shaft can be rotated by the frictional force of the O-ring. This is an easy-to-manufacture, small, and lightweight processing machine that rotates the shaft using this frictional force and can easily process a member fixed to one end of the shaft or a shaft using the shaft as a reference.

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the processing machine of the present invention will be described below with reference to the drawings.

FIG. 1 is a diagram showing the shape of a cylinder unit to be processed by a processing machine according to an embodiment of the present invention.

FIG. 2 is a top view showing, in cross section, the main components of the processing machine of the same embodiment. FIG. 3 is a side view showing the setting of the cylinder unit in the processing machine of the same embodiment.

FIG. 4 is a front view showing a method of fixing the cylinder unit in the processing machine of the same embodiment.

Processing by the processing machine of this embodiment is carried out as follows. One end of the shaft 1 of the cylinder unit is inserted into the O-ring 10 of the joint 11 in which the O-ring 10 is installed in the processing machine.

The joint 11 is pulled rearward in order to bring the reference surface 5 of the cylinder into close contact with the reference base 12 of the processing machine. The reference surface 5 of the cylinder is the reference base 12 of the processing machine.
By lowering the lever 31 after coming into close contact with the V-shaped fixing member 18
moves left and right to fix the outer circumference of the cylinder 4.

[0013] Rotate the joint 11 and remove the O-ring 1.
The shaft 1 inserted into the shaft 1 and the disk 3 fixed to the other end of the shaft 1 are rotated, and the cutting tool 17 is moved in the axial direction and circumferential direction to process the outer periphery and side surface of the disk 3.

The rotational configuration of the joint 11 is based on the motor 20.
This rotation drives a support pulley 24 provided at the other end of the motor fixing plate 23 and a belt 35 hooked around the motor pulley 22 via a motor pulley 22 fixed to a motor shaft 21. At the center of the belt 35 is a pulley 16 fixed to one end of the rotating shaft 13. The rotating shaft 13 has a bearing 1
4 and a housing 15, and a joint 11 is fixed to the other end of the rotating shaft 13.

The structure in which the reference surface 5 of the cylinder is brought into close contact with the reference base 12 of the assembly machine is that the motor fixing plate 23 is fixed to the motor slide base 26, and the housing fixing plate 27 is also fixed to the housing slide base 28. There is. The motor slide base 26 and the housing slide base 28 are connected to each other by a connecting plate 29, and by rotating the handle 30, the connecting rod 25 connecting the handle 30 and the housing slide base 28 moves linearly, and the housing slide base By pulling 28, the joint 11 is pulled rearward.

[0016]

[Effects of the Invention] Since the present invention is constructed as described above, the processing machine has a simple construction and can be easily miniaturized. Moreover, it is possible to easily process products with stable quality and high precision.

When the cylinder unit processed according to the present invention was installed in an actual machine, good recording and reproducing results were obtained.

This means that by employing the method of the present invention, various parts with a rotating configuration that require high precision, such as cylinder disks and flyfoils in video motors, etc. can be easily machined. It means that it is possible.
