Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an automated grinding system, and more particularly to an automated system suitable for grinding similar shaped workpieces.

[0002]

2. Description of the Related Art A conventional grinding system is shown in FIG.
As shown in FIG. 3, tooling information corresponding to the shape and size of the work W is input to the NC device 13 via the tape 21 (or floppy disk), and based on the tooling information, the NC device 13 causes the grindstone 1, the spindle center 3 to operate. , The tailstock center 6, the work rests 7, 8, 9 and the measuring portions 11, 12 of the direct sizing device 10, etc. are controlled.

[0003]

However, according to the conventional automation system, even if the workpiece W has a similar shape,
In order to automate the machining, it is necessary to change the initial setting value of the work engaging element according to the change of the shape dimension and input all the tooling information to create the machining program, which is very complicated. There was a problem that the program became complicated. Further, conventionally, it has been attempted to preliminarily input various tooling information to the NC device to automate the machining, but in this case, the machining sequence of the work may be limited, resulting in lack of flexibility. was there. Therefore, an object of the present invention is to provide a system capable of easily achieving automation of grinding without complicating a machining program or limiting a machining sequence.

[0004]

In order to solve the above-mentioned problems, an automatic grinding process system according to the present invention provides a tool such as a work itself or a member such as a dog attached to the work corresponding to the size and shape of the work. A storage medium storing information is mounted, a reading device for reading tooling information of the storage medium is installed in a part of the machine, and the NC device is configured to control the work engaging element based on the output of the reading device. It

[0005]

According to the automated system of the present invention, the tooling information peculiar to the work to be processed is stored in the storage medium, and the storage medium is attached to a part of the work by using the dog for the work drive. When the work is loaded, the tooling information of the storage medium is read by the reading device and set in the NC device. In this case, if the workpiece has a similar shape, it is necessary to input only the tooling information of the workpiece engaging element related to the change in the dimension and shape into the storage medium, which simplifies the machining program and facilitates its creation work. After reading the information, each work engaging element is controlled by the NC device based on the set tooling information, and the work is ground into a predetermined size and shape.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the present invention will be described below with reference to the drawings. In the grinder shown in FIG. 1, W is a work, 1 is a grindstone, 2 is a headstock, 3 is a headstock center, 4 is a dresser, 5 is a tailstock, and 6 is a tailstock center. 7,
8 and 9 are work rests, 10 is direct sizing device, 11 and 1
Reference numeral 2 is the measuring unit, and 13 is the NC device. Reference numeral 14 is a dog attached to one end of the work W. The dog 14 is connected to a main shaft (not shown) via a pin 15 and a drive plate 16 to transmit the rotation of the main shaft to the work W. There is. A storage medium 17 such as a tool ID card is attached to the dog 14, and the storage medium 17 stores tooling information corresponding to the size and shape of the work W to which the dog 14 is attached. This tooling information is the control amount of each work engaging element, that is, the cutting amount (XA) and traverse amount (ZA) of the grindstone 1, the rotational speed (C) of the spindle center 3, the thrust force and the longitudinal length of the tailstock center 6. Direction position (ZG), longitudinal position (ZB, ZC, ZD) and radial position (XB, XC, X) of the work rests 7, 8, 9
D), the longitudinal positions (ZE, ZF) and the radial positions (XE, X) of the measuring units 11 and 12 in the direct sizing device 10.
F) etc. are included. On the other hand, a reading device 18 having a writing function is arranged on the headstock 2 so as to face the storage medium 17 in a non-contact state, reads the tooling information of the storage medium 17 and transfers it to the NC device 13, and after processing. The dimension information of the work W can be written in the storage medium 17. In the grinding automation system of the present embodiment configured as described above, the tooling information unique to the workpiece W to be machined is stored in the storage medium 17, and the storage medium 17 is stored.
Is attached to a part of the work W by using the dog 14 for the work drive. Then, when the work W is loaded between the spindle center 3 and the tailstock center 6, the tooling information of the storage medium 17 is read by the reading device 18 and transferred to the NC device 13, and the tooling information of the NC device 13 is read. Rewriting is set. In this case, a workpiece W of similar shape
In that case, only the information on the work engaging element related to the change in the dimension and shape may be input to the storage medium 17. For example, in the “tooling information” shown in FIG. 1, only the sizing information, the rest information, and the tailstock information are input to the storage medium 17, and the grindstone information and the spindle information are omitted. Therefore, the machining program can be further simplified and the work of creating the program can be facilitated as compared with the conventional case.

Thus, when the tooling information is read, the grinder is operated, each work engaging element is controlled by the NC device 13 based on the set tooling information, and the work W is ground into a predetermined size and shape. After grinding is complete,
The dog 1 having the storage medium 17 mounted therein has the processing dimensions and the like in this process written in the storage medium 17 by the reading device 18.
4 is conveyed to the next process together with the work W, and the information of the storage medium 17 is used in the next process. In this way, the tooling information can always be managed integrally with the work W over a plurality of steps, and the information processing system can be simplified and made more efficient.

The present invention is not limited to the configuration of the above-described embodiment. For example, a read-only device may be used as the reading device 18, or the dog 14 and the reading device 18 may be used.
It is also possible to appropriately change the configuration of each part without departing from the gist of the present invention, such as arbitrarily changing the mounting position of, and including the dressing time or the dressing amount of the dresser 4 in the tooling information. It is possible.

[0009]

As described above in detail, according to the present invention, the work is attached to the storage medium via the work itself or a member attached to the work, and the tooling information of the storage medium is read by the reading device. Therefore, there is an excellent effect that the grinding process, in particular, the grinding process of the similarly shaped workpiece can be easily automated without complicating the machining program or limiting the machining order.
