である。Means for Solving the Problems〉 The structure of the thermal displacement prevention structure of the machine tool bed of the present invention that achieves the above object is designed to prevent the upper surface of the bed body from being exposed to chips, cutting fluid, or grinding fluid. By attaching a trough made of a thin plate such as an iron plate, creating a trough structure to provide a space between this trough and the top surface of the bed body, and constantly flowing liquid such as cutting fluid or grinding fluid into this space,
It is characterized by preventing the heat of chips, cutting fluid, and grinding fluid applied to the upper surface of the trough from being directly transmitted to the bed body.

This will cut off the transfer of heat to the bed and cool the bed itself. Therefore, the bed body maintains a stable temperature equal to or comparable to that of the liquid, and is not affected by temperature changes in the surrounding air.

、加工精度の低下も少なくなるものである。FIG. 1 shows an embodiment of the present invention. As shown in the figure,
A space is provided above the bed body 1, and a trough 11 made of a thin plate such as an iron plate is configured, and a coolant 1 is placed in the space.
3 is constantly being played. The coolant 13 is pumped up from the coolant tank 8 and used by a dedicated pump (not shown) that is separate from the pump 8. In this embodiment, the coolant 12 and the coolant 13 are stored together in the same coolant tank 8, but the present invention is not limited to this, and a separate dedicated coolant tank may be added and the coolant 13 may be constantly pumped from there. Also good. If the temperature of the coolant in this dedicated coolant tank is controlled and kept constant, the thermal displacement of the bed will be further reduced, and the deterioration of machining accuracy will be reduced.
