Next, we will discuss the effect.

In FIG. 1, the processing machine main body 8 of the machining center 1 processes the workpiece 4 while moving and displacing the tool 7 in three dimensions.
This processing is performed while selecting and exchanging a specific tool 7 from among the many tools 7 stored in the tool magazine 9.
The three-dimensional displacement of the tool 7 and the selection and replacement of the tool 7 are performed based on a machining procedure program by the control device 11. The workpiece 4 automatically machined in the machining center 1 in this manner is transferred to the constant temperature cleaning device 2 through the transfer port 7 5 or the like, and is set inside the cleaning chamber 22 of the main body 19 of the constant temperature cleaning device 2 . Next, the robot mechanism 15
6, the arm 14 of the robot mechanism 15 moves three-dimensionally along the surface of the work 4 according to a preset procedure while spouting pressurized liquid from the liquid jet nozzle 12, and adheres to the work 4. Chips, debris, etc. that are present are removed by the jetting pressure of pressurized fluid.

At this time, since the pressurized liquid is adjusted to a constant temperature by the liquid temperature adjusting means 28, the machining heat of the workpiece 4 is cooled and the temperature of the workpiece 4 is lowered.

When the ejection of the pressurized liquid is finished, compressed air is ejected from the ejection nozzle 13, and the arm 14 again performs three-dimensional movement and displacement to dry the workpiece 4 with the compressed air. Since this compressed air is also adjusted to a constant temperature by the air temperature adjusting means 32 and has the same temperature as the pressurized liquid, the workpiece 4 is quickly cooled to a predetermined temperature.

In the above, as described above, the robot mechanism 15 is driven by the drive control device 16 using the machining procedure program in the control device 11 of the machining center I, and the arm 14 is moved three-dimensionally to move and displace the machined part of the workpiece 4. However, since the pressurized liquid from the liquid jet nozzle 12 and the compressed air from the jet nozzle 13 are ejected intensively to the processing location, it is possible to efficiently remove chips and the like and cool processing heat.

The workpiece 4 that has been cleaned in the machining center 1 is sent to a post-processing step 3 by a transfer robot 6, for example. If the post-processing process 3 is an assembly process for the workpiece 4, the workpiece 4
Since chips and the like have been removed and the temperature has reached a predetermined temperature, assembly work can be performed immediately. Also, the post-processing process 3 is a measurement process in which, for example, the dimensions of the workpiece 4 are measured using a coordinate measuring machine. In some cases, the workpiece 4 has been cleaned and has a reference temperature suitable for carrying out the measurement operation, so that the measurement operation can be carried out immediately.

In this way, according to the constant temperature cleaning device 2, the workpiece 4 processed by the machining center 1 can be quickly cleaned and cooled, so that workpiece production can be performed without creating an excess stock of workpieces 4 between the machining center 1 and the post-processing process 3. The work 4 can be moved to the line, and the production efficiency of the entire production line can be improved. Further, the temperature of the pressurized liquid and compressed air is determined by the liquid temperature adjusting means 28 and the air temperature adjusting means 3.
2, and this temperature can be changed, so the temperature of the pressurized liquid and compressed air can be changed depending on the shape and size of the workpiece 4 to prevent thermal distortion from occurring in the workpiece 4. This makes it possible to improve the quality of the workpiece 4 and improve the yield.

Furthermore, when the post-processing process 3 is a measurement process, the measurement work can be performed quickly as described above, and the signal from the measurement result can be fed back to the machining center 1 before the next workpiece 4 is processed. This makes it possible to perform machining work by replacing the tool 7 with, for example, a tool 7 having a diameter that matches the target cutting value.

Furthermore, since the constant temperature cleaning device N2 is an online facility as described above, it can be used commonly for a plurality of machining centers 1, which is advantageous in terms of layout, and also has advantages in terms of work efficiency and economy.

Although the automatic production apparatus in this embodiment is a machining center, the constant temperature cleaning apparatus according to the present invention can also be applied to automatic production apparatuses other than machining centers. Furthermore, the constant temperature cleaning apparatus according to the present invention can be used not only as equipment for a workpiece production line, but also for cleaning workpieces that have been independently processed apart from the workpiece production line. Therefore, the constant temperature cleaning device can be used not only in common for a plurality of automatic production devices, but also for a single automatic production device.

[Effects of the Invention] According to the present invention, chips etc. from the workpiece can be quickly removed and machining heat can be cooled down, and there is no stagnation time for natural cooling, etc. Therefore, the assembly process, measurement process, etc. The workpiece can be quickly sent to the post-processing process, and the work efficiency of the workpiece production process as a whole can be improved.
