Description

Technical Field

[0001] This utility model belongs to the field of machine tool bed structure design, and specifically relates to a machine tool bed thermal compensation structure. Background Technology

[0002] In machining, heat generated by friction and cutting can cause localized temperature changes in the workpiece and machine tool, leading to localized thermal deformation and affecting machining accuracy. For example, large machine tools such as gantry planers and guideway grinders, due to their long beds, are prone to localized high temperatures during machining. Uneven temperature distribution across the lathe bed, especially with temperature differences between the guideway surface and the bottom surface, can cause significant bending deformation, thus affecting machining accuracy.

[0003] Based on this, this utility model designs a machine tool bed thermal compensation structure. Through a frame-type machine tool bed combined with baffles, it adjusts and designs the internal airflow channels of the machine tool bed to adapt to temperature differences, effectively reducing errors caused by thermal deformation and improving the precision and quality of machining. It can be widely used in machining and manufacturing in the automotive, aerospace, and precision machinery industries. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a machine tool bed thermal compensation structure to address the issues in the prior art. The technical solution adopted by this utility model is as follows:

[0005] A machine tool bed thermal compensation structure includes a machine tool bed, which is a cuboid structure. The machine tool bed has a first hollow section, a third chamber, and a fourth hollow section arranged longitudinally. There are two third chambers, which are located between the first hollow section and the fourth hollow section. A fan is installed on one of the third chambers.

[0006] The machine tool bed is provided with a plurality of transversely distributed transverse through holes, which penetrate the first hollow part, the third chamber and the fourth hollow part;

[0007] Wind b and wind b are alternately installed at the open ends of the plurality of transverse through holes. The wind b covers the transverse through holes, and the wind b is provided with a circular exhaust hole.

[0008] Furthermore, the machine tool bed is provided with two protruding bed guide rails, which are spaced apart. A second hollow portion is provided inside the bed guide rail, which is located in the longitudinal direction of the machine tool bed. The transverse through hole penetrates the second hollow portion.

[0009] Furthermore, both sides of the bed guide rail are provided with circular holes that connect to the second hollow part. The circular holes are located above the machine tool bed, and a baffle plate e is installed on the circular holes.

[0010] Furthermore, the wind deflector e is detachably connected to the circular hole by a snap-fit ​​mechanism, and both the wind deflector b and the wind deflector c are detachably connected to the transverse through hole by a snap-fit ​​mechanism.

[0011] Furthermore, multiple vertical through holes are distributed above the first hollow portion and the fourth hollow portion, and on the top of the machine tool bed.

[0021] The following will be based on the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Unless otherwise specified, the technical means used in the embodiments are conventional means well known to those skilled in the art.

[0022] A machine tool bed thermal compensation structure includes a machine tool bed 1, which is a cuboid structure. The machine tool bed 1 has a first hollow portion 101, a third chamber 103, and a fourth hollow portion 104 arranged longitudinally within it. Two third chambers 103 are provided, located between the first hollow portion 101 and the fourth hollow portion 104. A fan 8 is installed on one of the third chambers 103.

[0023] The machine tool bed 1 is provided with a plurality of transversely distributed transverse through holes, which penetrate the first hollow part 101, the third chamber 103 and the fourth hollow part 104.

[0024] Wind b4 and wind b4 are alternately installed at the open ends of the multiple transverse through holes. The wind b4 covers the transverse through holes, and the wind b4 is provided with a circular exhaust hole.

[0025] The machine tool bed 1, along its longitudinal direction (the length of the bed guide rail 9), has a first hollow portion 101, a third chamber 103, and a fourth hollow portion 104 spaced apart and arranged parallel to each other. The first hollow portion 101 and the fourth hollow portion 104 are through-hole structures, while the third chamber 103 is preferably open at one end and closed at the other. The fan 8 is installed at the open end of one of the third chambers 103. A transverse through-hole extends transversely from one end of the machine tool bed 1 to the other. A circular exhaust hole on the baffle plate c5 is used to discharge gas, while the side of the baffle plate b4 is used to cover the transverse through-hole.

[0026] In its specific implementation, this utility model introduces outside air through the fan 8. The air moves longitudinally within the third chamber 103, then diffuses through the transverse through-holes, and is discharged from the circular exhaust holes on the baffle plate c5. This helps to maintain a uniform and stable temperature in the machine tool bed 1, preventing high temperature differences from forming in various parts of the machine tool bed 1. Furthermore, by arranging the number and position of the baffle plates c5 and b4, the air output direction can be changed, thereby altering the gas flow path within the machine tool bed 1. The gas flow path can be designed according to the actual high-temperature and low-temperature areas of the machine tool bed 1, thereby improving the thermal compensation effect and ensuring the overall temperature uniformity of the machine tool bed 1.

[0027] Furthermore, the machine tool bed 1 is provided with two protruding bed guide rails 9, which are spaced apart. A second hollow portion 102 is provided within each bed guide rail 9, located longitudinally on the machine tool bed 1. The transverse through-hole penetrates the second hollow portion 102. The bed guide rails 9 are existing technology and are used to arrange related fixtures, cutting tools, and other components. The first hollow portion 101, the second hollow portion 102, the third chamber 103, and the fourth hollow portion 104 are arranged side-by-side and spaced apart, with the transverse through-hole penetrating all four.

[0028] Furthermore, both sides of the bed guide rail 9 are provided with circular holes that connect to the second hollow portion 102. The circular holes are located above the machine tool bed 1, and a baffle plate e7 is installed on the circular holes.

[0029] The number of baffles e7 can be adjusted according to the actual situation. If the temperature of the bed guide rail 9 is high, the number of baffles e7 can be set to be less than that of the round hole, so that the round hole forms an exhaust port, which improves the cooling effect on the bed guide rail 9 and reduces the temperature difference between the bed guide rail 9 and the machine tool bed 1.

[0030] Furthermore, the wind deflector e7 is detachably connected to the round hole by a snap-fit ​​mechanism, and both the wind deflector b4 and the wind deflector c5 are detachably connected to the transverse through hole by a snap-fit ​​mechanism.

[0031] Furthermore, multiple wind baffles a3 can be detachably connected to each of the two third chambers 103, and the wind baffles a3 are located in the direction of the transverse through hole.

[0032] Furthermore, multiple vertical through holes are distributed above the first hollow portion 101 and the fourth hollow portion 104, and on the top of the machine tool bed 1. The vertical through holes connect the corresponding first hollow portion 101 and fourth hollow portion 104. A baffle plate d6 or a cover plate is provided on the vertical through holes, and a square exhaust hole is provided on the baffle plate d6.

[0033] Furthermore, both the wind deflector d6 and the cover plate are detachably connected to the vertical through hole via a snap-fit ​​mechanism.

[0034] In this invention, wind deflectors b4, c5, d6, and e7 are all fixed by snap-fitting. A circumferential groove can be provided on their end faces for snap-fitting, facilitating installation and removal. Wind deflector a3 can be fixed by bolts or other means.

[0035] The function of baffle a3 is to create an obstruction in the transverse direction of the transverse through hole to change the air flow path; the function of baffle b4 and baffle c5 is to jointly form the transverse output position control of air, thereby changing the flow path; the function of baffle d6 is to control the vertical output position of air; the function of baffle e7 is to control the air output position on the bed guide rail 9.

[0036] This invention, through the coordination of the number and position of the various baffles, can form multiple airflow channels, thereby adapting to the temperature compensation requirements of different areas of the machine tool bed 1. It should be noted that the fan 8 can blow out cold or hot air, thereby cooling or heating the machine tool bed 1.

[0037] Furthermore, the machine tool bed 1 is equipped with multiple temperature sensors 2. The function of the temperature sensors 2 is to detect the temperature of the machine tool bed 1 during actual operation. Multiple high-precision temperature sensors 2 (such as thermocouples, thermistors, or infrared sensors) are arranged in key parts of the bed (such as the spindle, guide rails, base, etc.) to monitor the temperature changes of key parts of the machine tool bed in real time, ensuring that the heat distribution of the bed can be fully captured.

[0038] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Any modifications, alterations, alterations, or substitutions made by those skilled in the art to the technical solutions of the present utility model without departing from the spirit of the present utility model shall fall within the protection scope defined by the claims of the present utility model.
