The present invention relates to a multi-processing device that integrally performs processing using a machine tool such as a grinder or a machining center, and radar processing.

[Technical background of the invention and its problems] When processing metal materials into products, various processing steps are usually required. For example, when machining a workpiece such as an electric motor shaft that requires high machining dimensional accuracy and requires locally increasing hardness, the following machining steps are required. That is, after finishing the cutting process, it is necessary to locally harden the workpiece by induction hardening, and then perform grinding to correct deformation due to thermal strain caused during the hardening.

When processing workpieces such as those mentioned above, it is common to perform one type of processing using one device, and in particular, shape processing such as cutting or grinding and heat treatment are completely different. equipment was required.

Therefore, there are problems in that a large number of workers are required and work efficiency is poor.

It is an object of the present invention to provide a complex machining equipment 41j that can perform the machining operations of the present invention in an integrated manner, thereby reducing the number of workers and improving the work efficiency.

To achieve the above object, the present invention accomplishes the following (Q?). Namely, the present invention provides a lathe,
A laser oscillator is installed near the machining machine such as a grinding machine, a milling machine, etc., and the above-mentioned method is used to guide the laser beam from this laser oscillator to the processed part of the workpiece. A mirror is added to the machine tool, and a beam lens is attached to the machine i3:i to focus the laser beam reflected by the mirror onto the workpiece. A feature of tp is that the machining work and the machining work using the laser beam are performed integrally.

[Embodiments of the invention]

The first one is O showing an embodiment of the present invention in which the machine tool is an NC lathe. In the figure, 1 is the chuck of the NC lathe, a center 3 is attached to the tailstock 2 facing it, and several workpieces 4 are placed between the chuck 1 and the center 3. I get kicked. On top of the reciprocating table 6, which slides along the guide section 5 in the directions 11-1 and 11-1, there is a cross-feeding table 11-1 which moves downward in the -1 direction. 7 is disposed, and furthermore, a tool rest 8 that slides in the horizontal direction is disposed above the transverse feed table 7. A cutting tool 9 is attached to the tool rest 8.

A mirror 10 is disposed on the 1111 plane of the cross feed table of the NC lathe main body having such a structure so that the needle face forms an angle of 45 degrees. A laser beam oscillator 11 is disposed near the NC lathe body. Thus, the laser beam 12 emitted from the oscillator 11 takes an optical path parallel to the sliding direction of the carriage, and the mirror 10
The beam is reflected and irradiated onto the workpiece 4.

Further, a condenser lens 13 is disposed on the side surface of the tool post 8. The condensing lens 13 is disposed such that its lens surface faces the object to be measured 4 and is positioned on the optical path of the laser beam 12. In front of the oscillating section of the laser beam oscillator 11, a shutter 14 is provided to cut off the overload of the laser beam 12.

The tool rest 8 of the NC lathe main body has a black paint injection nozzle 15 and a hot air injection nozzle 16 with injection ports connected to the workpiece 4.
A few shots have been fired towards.

The nozzle 15 is connected to a black paint delivery pump 19 via a tube 17 and a valve 18. Similarly, the upper L nozzle 16 is also used for sending hot air through the tube 2° and the valve 2). Connected to Nzo22.

It should be noted that n1■ The vertical sliding of the marking table 6, the vertical sliding of the horizontal feed table 7, and the horizontal sliding of the tool rest 8.
,...: 1ilJ, the operation of the laser beam oscillator 11, the opening and closing of the shutter 14, and the opening and closing of the valves 18 and 21 are configured to be controlled by a numerical control device (not shown). .

The mounting of this embodiment having the above configuration operates as follows. FIG. 2 is a diagram for explaining the order in which the workpieces 4 are machined according to this embodiment. Here, for convenience of explanation of the operation, it is assumed that the workpiece 4 is machined into a multi-stage shaft, and furthermore, the portion between grooves A3 and A4 in the figure is hardened.

Several cutting tools 9 are placed in the turret 8 and are initially at the AO position. Note that the vertical position of the cutting edge portion of the cutting tool 9 is located at the central axis of the workpiece 4, and this vertical position does not change thereafter. After rotating the workpiece 4 with the chuck 1 of the NC lathe, the cutting edge of the cutting tool 9 is
Move to position 1. This movement is performed by automatically moving the numerically controlled carriage 6 and tool rest 8. From now on, the cutting edge of bite 9 is A1 → A2 → A3.
→A 4. The workpiece 4 is cut into a multi-stage JFIl+ shape through one pass of the machining thread of +A5.

By the way, in addition to the cutting process using the tool 9, black paint and warm air were injected through the valves 18 and 21.
The above black paint is applied to the hardened parts from size 3 to A4 and allowed to dry. This is to prevent reflection of the laser beam (ljj 12) during the 1/- laser hardening process to be performed later. That is, when the nozzle 15 attached to the tool rest 8 comes to a position facing A3, the valve 18 opens and the black paint sent from the pump 9 is transferred to the duplex 17?
i Street / Suru 15 yo Shi spout. Upper 11[; Valve 18υ remains open and closes when the nozzle 15 comes to the position opposite A4. Therefore, the black paint is deposited on the hardened portion between A3 and A4. Also,
When the nozzle 16 comes to the position facing the A3, the valve 21 opens and hot air sent from the bomb f22 passes through the tube 20 and is injected from the nozzle 16.

The above-mentioned lubricant 2) continues to open and closes when the nozzle 16 comes to the position facing A4Vc. therefore,
The above hot air is used to harden workpiece 4 from A3 to A4.
Dry the black paint attached to the lt. After performing the cutting process and applying and drying the black paint by the operations described above, laser hardening process is performed.

Before starting the laser hardening process, place 1A5
D Move the cutting edge of cutting tool 9 that has reached K to position A7 along the path A5 → A6 → A7.

When the cutting edge of the cutting tool 9 is at the position A7, the laser beam 12 oscillated from the laser beam oscillator 1 and passing through the mirror 10 and the condensing lens 13 strikes the workpiece 4.
A3, which is the 91'M part of the hardened part, is irradiated. Next, the tool post 8 is moved laterally so that the laser beam 12 is focused on the A3 portion. The focused position is assumed to be ff, where the cutting edge of the cutting tool 9 is at A8.

Then, at the same time as the workpiece 4 is rotated by the chuck 1, the shutter 14 is opened and the laser beam 12 is irradiated onto the A3 portion of the workpiece 4. Next, the tool rest 8'f is moved in the vertical direction, and the shutter 14 is closed when the cutting edge of the cutting tool 9 reaches the position 89. The cutting edge part of bite 9 is A above.
At position 9, the laser beam 12 irradiates the hardened portion A4 of the workpiece 4. Through the series of operations described above, the hardened portions A3 to A4 of the workpiece 4 are laser hardened.

In this way, this device applies and dries the paint along with the cutting process, and then performs the same process, V・f, ('
In this case, the workpiece 4 can be removed, and as a result, the number of workers can be reduced and the work efficiency can be improved. In addition, by concentrating the laser beam πho12I''i in the laser hardening process as in this practical example, the irradiation area can be significantly reduced, and the energy density can be easily increased. Hardening can be performed quickly and instantaneously, causing less thermal distortion to the workpiece, and as a result, there is no need to perform finishing work such as grinding after hardening, further increasing work efficiency. I can do it.

Note that the present invention is not limited to the above-mentioned actual h°C example. For example, a machine tool to which the present invention is applied is an NC
The machine is not limited to a family machine, and may be a manual lathe, a grinding machine, a machining center, or the like. In that case, as in the above embodiment, a laser beam oscillator is disposed near the machine tool, and the laser beam emitted from the laser beam oscillator irradiates the workpiece as the processing tool of the machine tool operates. It is easy to attach a mirror and a condensing lens to the lens, and the same effect as in the actual Mli example can be obtained. Further, in the above embodiment, the laser beam oscillator is used for hardening, but it can also be used for welding, cutting, etc.

〔Effect of the invention〕

The present invention has the advantage that processing work using a machine tool and a laser can be performed in an integrated manner, resulting in a reduction in the number of workers and an improvement in work efficiency.
