本発明は温度制御機能を有する加工装置に関す

て恒温室とほぼ同じ状態を経済的に作り出し加工
穴中心の位置誤差をなくし高精度の機械加工を達
成することである。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a processing device having a temperature control function.The purpose of the present invention is to economically create conditions almost the same as a constant temperature room in a factory without air conditioning equipment, eliminate positional errors in the center of a processed hole, and increase height. The goal is to achieve precision machining.

温の変化が激しく一日の内でも朝昼晩と変化し、
また四季の移り変りによつても変化し、その温度
差は極めて大きい。 In general, installing air conditioning equipment in a vast machining factory requires a huge amount of equipment cost and consumes a large amount of electricity, so the current situation is that it is rarely installed. In general factories without air-conditioning equipment, the temperature changes dramatically throughout the day, from morning to night.
It also changes with the changing seasons, and the temperature differences are extremely large.

作物の材質の相違による線膨張係数の違いも加工
精度低下の要因となつている。 As a result, relative thermal displacement between the workpiece and processing equipment causes a positional error in the center of the machined hole, making it difficult to maintain the accuracy of the workpiece.In addition, the coefficient of linear expansion is due to the difference in material between the shaft head of the processing equipment and the workpiece. The difference is also a factor in reducing machining accuracy.

たらす。 Figure 1 shows the relationship between the shaft head 1 of the processing device and the workpiece W, and shows the relationship between the thermal expansion of the center-to-center distance between the spindles 2 and 3 of the shaft head 1 and the center-to-center distance of the machined hole of the workpiece W. Thermal expansion also varies depending on the difference in linear expansion coefficient between the shaft head 1 and the workpiece W, and also due to the difference in heat capacity between the shaft head 1 and the workpiece W, the temperature difference due to atmospheric temperature changes and the heat generation source. There is also a considerable difference in thermal expansion between the two due to an increase in the temperature of the shaft head. Therefore, if there is a difference in thermal expansion between the two at the time of processing,
When the temperature returns to room temperature, a dimensional error will occur in the machined hole pitch, resulting in a decrease in workpiece processing accuracy.

発生は防止できる。 By the way, if the temperature of the shaft head 1 and the temperature of the workpiece W can be kept at the same constant temperature, it will be possible to create almost the same state as when machining was performed in a constant temperature room. As a convenient means for this purpose, lubricating oil kept at a constant temperature is circulated through the shaft head 1, and the workpiece W
One idea would be to supply a large amount of cutting fluid that is kept at a constant temperature and perform machining at the same temperature as the cutting fluid temperature. However, since the amount of cutting fluid supplied is large,
Controlling this to a constant temperature throughout the year not only requires a large-capacity temperature control device;
When the temperature difference with the atmospheric temperature is large, such as in summer or winter, energy consumption increases, which is not preferable. If the temperature of the cutting fluid is changed in stages according to seasonal temperature changes, the temperature difference with respect to the atmospheric temperature can be reduced. On the other hand, shaft head 1
By changing the temperature of the lubricating oil in conjunction with changing the setting of the cutting fluid temperature, it is possible to equalize the amount of thermal expansion of the shaft head 1 and the workpiece W at the time of machining, making it economically possible to maintain a constant temperature even in general factories. It is possible to create a machining environment that is almost the same as that in the chamber, thereby preventing deterioration in machining accuracy and reducing energy consumption. If there is a difference in the coefficient of linear expansion due to the difference in the constituent materials of the workpiece and the shaft head, it can be corrected to some extent by providing a difference in the set temperatures of the cutting fluid and the shaft head lubricating oil. In other words, if the ratio of the difference between the workpiece set temperature and the reference temperature (20 degrees Celsius) and the difference between the shaft head set temperature and the reference temperature is the inverse ratio of the linear expansion coefficients of the workpiece and the shaft head, then ,
The amount of thermal expansion of the workpiece and the amount of thermal expansion of the shaft head at the time of machining become equal, and positional errors in the center of the machined hole can be prevented from occurring.

Therefore, as a preferable example, when starting up the processing equipment, the average room temperature from several days to a week before to the previous day is set as the set temperature, and the lubricating oil and cutting fluid temperatures are maintained at that temperature throughout the day. As a result, even if the room temperature changes, the workpiece and shaft head are kept at the same temperature, which reduces the error between the machining hole pitches due to the difference in relative thermal expansion, and the center of the machining hole relative to the workpiece mounting surface. Position errors are prevented. or,
As the temperature difference between lubricating oil and cutting fluid can be minimized due to room temperature changes throughout the day, not only can the power consumption required to maintain the set temperature be extremely small, but also each temperature control device can 3
There is also the advantage that the heaters and coolers of 3 and 42 can be of small capacity. Furthermore, by updating the set temperature one after another according to the average temperature up to the previous day, the set temperature can be made to follow seasonal changes, and the temperature difference between lubricating oil and cutting fluid relative to room temperature can be kept to a minimum throughout the year. can.

係を保つようにする。 If the material of the workpiece and the shaft head are the same, the set temperature of the cutting fluid and the set temperature of the lubricant should be the same, but if the materials are different and there is a difference in linear expansion coefficient, this line It is necessary to provide an appropriate temperature difference between the respective set temperatures of the cutting fluid and the lubricating oil depending on the ratio of expansion coefficients. For example, with 20 degrees Celsius as the reference temperature, the ratio of the difference between the set temperature of the cutting fluid with respect to this reference temperature and the difference between each set temperature of the lubricating oil with respect to the reference temperature is the inverse of the linear expansion coefficient of the workpiece and the shaft head. Try to maintain a comparable relationship.

It is. In this case, the ratio of the temperature difference △t 1 of the cutting fluid set temperature t 1 with respect to the reference temperature and the temperature difference △t 2 of the lubricating oil set temperature t 2 with respect to the reference temperature is △t 1 /△t 2 = 1/2, If the average room temperature is 15℃, the cutting fluid temperature is set.

る利点を有する。 In such a configuration, the average room temperature during the operating hours of the processing equipment is detected every day and stored over a certain period of time, and the average room temperature for the next day is predicted by calculating the average. The preset temperatures for the cutting fluid and lubricating oil are set at startup and are maintained at a constant temperature throughout the day. Since both the workpiece and the shaft head are kept at a constant temperature throughout the day, it is possible to create conditions similar to a constant temperature room in a general factory, and to reduce errors between machined hole pitches due to thermal expansion and the workpiece mounting reference plane. Positional errors to the center of the machined hole are prevented. Furthermore, since the temperature difference between the cutting fluid and the lubricating oil relative to room temperature can be made extremely small, there is an advantage that the energy consumption required for temperature control can be reduced.

Especially at the change of seasons, it is preferable to further divide the seasonal temperature difference into several stages as shown by the two-dot chain line and select a set temperature according to the change of seasons.
