Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing machine for processing a rotating shaft assembly that includes a built-in motor, and particularly to a processing machine that rotates the motor itself and processes using the rotational force.

Conventionally, in a rotary shaft assembly processing machine in which a rotary shaft assembly with a built-in motor is attached to the chuck of the rotating body and multiple processes are performed at multiple processing positions using an indexing means, the assembly is processed using a cutting means. The inner part of the machine is rotated to process the necessary parts, and there is no one that utilizes the rotational force of a built-in motor. However, due to manufacturing errors, the designed rotation center and the motor's own rotation center rarely match exactly. If so, the center axis may slightly deviate from the actual rotation center of the motor. For this reason, problems remain in machining rotating shaft assemblies that require strict centering accuracy.

This invention was made in view of such conventional problems, and a slip ring is provided on the rotating body, and the motor itself is connected to a power source and rotated at the required processing position to achieve strict centering accuracy. An object of the present invention is to provide a processing machine for rotating shaft assemblies that can be processed.

The embodiment shown in the figures will be explained in detail below. 1st
In the embodiment shown in FIG. 1 and FIG. 2, the index motor 1 rotates the rotating body 3 by 90 degrees to the first station (No. 1) and the second station (No. 1).
2) Position at four positions: the third station (No. 3) and the fourth station (No. 4). The rotating body 3 is provided with chucks 5 at four locations separated by 90 degrees, and the outer member 7a of the rotating shaft assembly 7 can be fixed to each chuck 5.

A slip ring 9 is provided on the front or back surface of the rotating body 3.
are provided concentrically and insulated, and a brush 11 is brought into elastic contact with a part of the slip ring 9. This brush 11 is connected to an external power source and conducts electricity to the slip ring 9. Further, a connector 13 serving as a connecting means is connected to a portion of the slip ring 9 close to each chuck 5.

A rough machining device 15, an end face finishing device 17, and an external shape machining device 19 are installed at positions corresponding to each station of the rotating body 3. In addition, the Kelley drive device 21 of the braid 7 is installed at the second station and the fourth station.
It is located at the station.

The operation of the rotating shaft assembly processing machine will now be described. This processing machine has an outer member 7 as shown in FIG.
It is used to process a rotating shaft assembly 7 such as a motor configured to support a rotating member 7b at point a.

Loading the Braid First, each chuck 5 is made to grip the outer member 7a of the braid 7 at the loading/unloading position of its first station (No. 1).

Rough machining Next, the index motor 1 is driven to rotate the braid 7 at the first station (No. 1) by 90 degrees to bring it to the second station (No. 2). At this second station (No. 2), the Keret drive device 21 is engaged with the rotating member 7b of the braid 7, and rough machining is performed by the rough machining device 15 while rotating the rotary member 7b.

Precision finishing Once rough machining is completed, index motor 1
As a result, the rotating body 3 is further rotated by 90 degrees, and the braid 7 that was at the second station (No. 2) comes to the third station (No. 3).

At this third station (No. 3), the connector 13 is connected to the motor lead wire 7c of the braid 7, electricity is passed to the motor via the brush 11 and the slip ring 9, and the rotating member 7b is connected to the outer member 7a. and start rotating.

In this manner, the rotary member 7b is rotated by itself, and the end face finishing device 17 performs precision finishing on the portion of the rotary member 7b where the precise center must be brought out.

External Diameter Machining After the finishing machining of the rotating member 7b is completed, the index motor 1 moves it to the third station (No.
Move the braid 7 in 3) to the 4th station (No. 4)
Rotate 90 degrees to the position.

At this fourth station (No. 4) as well, the outer diameter cutting is performed while rotating the rotary member 7b by a Kelley drive device (not shown).

Product unloading Once processing is complete, the product is transferred to the 4th station (No.
4) Kumimono 7 is placed in the first station (No.
It is further rotated 90 degrees to position 1). At this first station (No. 1), the processed products are carried out from each chuck 5, and unprocessed braids 7 are newly carried into the chuck 5.

In this way, the braid 7 set in each chuck 5 is rotated by 90 degrees by the index motor 1, and each processing device 15, 17, 1
9, they are processed one after another and shipped out as products. Then, when each braid 7 comes to the third station (No. 3), the connector 13 is connected to the motor lead wire 7c, and precision finishing of the rotating member 7b is performed using its own rotational force. It is.

In addition, in the above embodiment, an example was shown in which the rotating body is processed at four positions at 90 degrees each, but there is no particular limitation thereto, and the processing positions may be determined depending on the braid to be processed.

This invention relates to a processing machine that rotates a rotating body to position and process a rotary shaft assembly at a plurality of processing positions, and the present invention provides a slip ring on the rotating body and connects it to an external power source, and a means for connecting the slip ring to the slip ring. Since it is connected to the motor lead wire of the braid held in the chuck, electricity can be passed to the braid in each chuck even when the rotating body rotates, and each braid can rotate by itself. It has the advantage of being able to process the outer periphery around the actual axis of rotation and with precise center accuracy.
