Description

Technical Field

[0001] This utility model relates to the field of machine tool technology, and in particular to a mounting base, a worktable and a machine tool. Background Technology

[0002] Machine tool operating accuracy is highly sensitive to temperature changes. Taking metal cutting machine tools as an example, the high operating accuracy of metal cutting machine tools is mainly reflected in the accuracy of the feed system. In the feed system, a leadscrew and nut typically drive the worktable. During the operation of a metal cutting machine tool, the leadscrew and nut are constantly subjected to cutting forces, causing their temperature to rise continuously. Thermal expansion of the leadscrew and nut leads to problems such as increased lead, thus affecting the positioning accuracy of the feed system. In related technologies, passive cooling of the leadscrew and nut is mostly achieved through air convection. However, the internal protection of the machine tool's feed system creates a near-sealed space around the leadscrew and nut. When airflow is poor, passive cooling is insufficient to address the rising temperature of the leadscrew and nut, thereby affecting the machine tool's operating accuracy. Utility Model Content

[0003] This application provides a mounting base, a workbench, and a machine tool to solve the problem in related technologies where passive heat dissipation of the nut via air convection is insufficient to cope with the temperature rise of the nut.

[0004] According to a first aspect of the embodiments of this application, a mounting base is provided for mounting a nut. The mounting base body is provided with a temperature control system. A heat exchange medium circulates in the temperature control system to absorb heat from the mounting base body. The temperature control system includes a first heat exchange channel and a second heat exchange channel formed inside the mounting base body. One end of the first heat exchange channel extends to the surface of the mounting base body and forms a liquid inlet. The other end of the first heat exchange channel communicates with the second heat exchange channel. At least one end of the second heat exchange channel extends to the surface of the mounting base body and forms a liquid outlet. The extension directions of the first heat exchange channel and the extension directions of the second heat exchange channel are inclined to each other.

[0005] Optionally, the temperature control system further includes a third heat exchange channel formed inside the base body, the third heat exchange channel being connected to the first heat exchange channel and / or the second heat exchange channel, the extension direction of the third heat exchange channel being inclined to the extension direction of the first heat exchange channel, and / or the extension direction of the third heat exchange channel being inclined to the extension direction of the second heat exchange channel.

[0006] Optionally, the diameter of the first heat exchange channel is smaller than the diameter of the second heat exchange channel.

[0007] Optionally, multiple first heat exchange channels are spaced apart inside the base body, and multiple second heat exchange channels are spaced apart inside the base body in the same number as the first heat exchange channels.

[0008] Optionally, the base body is further provided with a mounting hole for mounting a nut, wherein a notch is provided on the wall of the mounting hole, which extends through the axial and radial directions of the mounting hole respectively.

[0009] Optionally, an elastic contact element is also provided on the wall of the mounting hole.

[0010] Optionally, an insulation layer is also provided on the outer surface of the base body.

[0011] Optionally, the base body further includes a controller, a first temperature detection sensor, and a second temperature detection sensor. The first temperature detection sensor is used to detect the liquid temperature in the first heat exchange channel, and the second temperature detection sensor is used to detect the liquid temperature in the second heat exchange channel. The controller adjusts the temperature of the heat exchange medium according to the detection values ​​of the first temperature detection sensor and the second temperature detection sensor.

[0012] According to a second aspect of the embodiments of this application, a workbench is provided, the workbench including a workbench body, a lead screw, a lead screw, and a mounting base as described in any one of the above, the workbench body being slidably disposed, the base body being connected to the workbench body, the lead screw being connected to the lead screw mounting base and threadedly engaged with the lead screw.

[0013] According to a third aspect of the embodiments of this application, a machine tool is provided, the machine tool including the worktable described above.

[0014] The solution provided by this utility model has the following advantages compared with the prior art:

[0015] With the above technical solution, when the mounting base is applied inside a machine tool and a nut is installed, taking coolant as the heat exchange medium as an example, the coolant can enter the first and second heat exchange channels through the inlet. As the coolant flows, it absorbs heat to cool the base body. Since the nut is installed on the base body, when the base body temperature decreases, the air temperature near the base body also decreases. The cooled air can absorb heat from the nut to lower its temperature. Simultaneously, the part of the base body in contact with the nut during installation also absorbs heat to reduce the nut's temperature. Furthermore, the extension directions of the first and second heat exchange channels are inclined or perpendicular to each other. Thus, when the coolant flows from the first heat exchange channel into the second heat exchange channel, the change in flow direction reduces the coolant velocity, allowing the coolant to remain within the base body as much as possible, ensuring sufficient heat absorption. Meanwhile, this application, through the design of a temperature control system, enables the silk mother to be actively cooled, and the cooling effect on the silk mother is not affected by the external environment. Unlike related technologies that use air convection to passively dissipate heat from the silk mother, it is no longer necessary to deal with the problem of the silk mother's temperature rising when the air flow is poor.

For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to mechanical connections or electrical connections; they can refer to direct connections or indirect connections through an intermediate medium.

[0030] According to the first aspect of the embodiments of this application, such as Figures 1 to 5 As shown, a mounting base is provided for mounting a nut. The mounting base body 1 is provided with a temperature control system. The temperature control system has a circulating heat exchange medium for absorbing heat from the mounting base body 1. The temperature control system includes a first heat exchange channel 2 and a second heat exchange channel 3 opened inside the mounting base. One end of the first heat exchange channel 2 extends to the surface of the mounting base body 1 and forms a liquid inlet 21. The other end of the first heat exchange channel 2 is connected to the second heat exchange channel 3. At least one end of the second heat exchange channel 3 extends to the surface of the mounting base body 1 and forms a liquid outlet 31. The extension direction of the first heat exchange channel 2 and the extension direction of the second heat exchange channel 3 are inclined to each other.

[0031] With the above technical solution, when the mounting base is applied inside the machine tool and a nut is installed, taking coolant as the heat exchange medium as an example, the coolant can enter the first heat exchange channel 2 and the second heat exchange channel 3 through the inlet 21. As the coolant flows, it absorbs heat to cool the base body 1. Since the nut is installed on the base body 1, when the temperature of the base body 1 decreases, the temperature of the air near the base body 1 will also decrease. The cooled air can absorb heat from the nut to lower its temperature. Simultaneously, the part of the base body 1 that contacts the nut during installation also absorbs heat to reduce the temperature of the nut. Furthermore, the extension direction of the first heat exchange channel 2 and the extension direction of the second heat exchange channel 3 are inclined or perpendicular to each other. Thus, when the coolant flows from the first heat exchange channel 2 into the second heat exchange channel 3, the flow rate of the coolant decreases due to the change in flow direction, allowing the coolant to remain in the base body 1 as much as possible, ensuring sufficient heat absorption. Meanwhile, this application, through the design of a temperature control system, enables the silk mother to be actively cooled, and the cooling effect on the silk mother is not affected by the external environment. Unlike related technologies that use air convection to passively dissipate heat from the silk mother, it is no longer necessary to deal with the problem of the silk mother's temperature rising when the air flow is poor.

[0032] The temperature control system may further include a third heat exchange channel 4 formed inside the base body 1. The third heat exchange channel 4 is connected to the first heat exchange channel 2 and / or the second heat exchange channel 3. The extension direction of the third heat exchange channel 4 is inclined to the extension direction of the first heat exchange channel 2, and / or the extension direction of the third heat exchange channel 4 is inclined to the extension direction of the second heat exchange channel 3. In this way, the coolant entering the first heat exchange channel 2 can enter the third heat exchange channel 4, and the coolant entering the second heat exchange channel 3 can also enter the third heat exchange channel 4. Through the third heat exchange channel 4, the flow path of the coolant is increased, so that the coolant covers a wider area of ​​the base body 1. The coolant can stay in the base body 1 as much as possible and cover the base body 1 as much as possible, so that the coolant can fully stay in the base body 1 and absorb heat, ensuring the cooling effect of the coolant on the base body 1, and further ensuring the cooling effect on the nut.

[0033] In addition to absorbing heat from the base body 1 and cooling it down as mentioned above, the temperature control system can also release heat during actual use to insulate and heat the base body 1, thereby regulating its temperature. For example, when the mounting base of this application is used in a colder environment, the temperature control system can also release heat to ensure that the temperature of the base body 1 does not drop too low and affect its service life.

[0034] The diameter of the first heat exchange channel 2 can be smaller than the diameter of the second heat exchange channel 3. By adjusting the diameters of the first heat exchange channel 2 and the second heat exchange channel 3, the flow rate of the coolant can be adjusted. When the diameter of the first heat exchange channel 2 is smaller than the diameter of the second heat exchange channel 3, when the coolant flows from the first heat exchange channel 2 into the second heat exchange channel 3, the flow rate of the coolant in the second heat exchange channel 3 will decrease due to the increased diameter of the second heat exchange channel 3. This allows the coolant to remain sufficiently within the base body 1 and absorb heat, ensuring the cooling effect of the coolant on the base body 1, and further ensuring the cooling effect on the nut.

[0035] In some embodiments, multiple first heat exchange channels 2 can be spaced apart inside the base body 1, and multiple second heat exchange channels 3 can be spaced apart inside the base body 1 in the same number as the first heat exchange channels 2. This increases the flow path and range of the coolant through multiple first heat exchange channels 2 and multiple second heat exchange channels 3, allowing the coolant to remain within the base body 1 as much as possible and cover it as much as possible. This ensures the coolant can fully remain within the base body 1 and absorb heat, guaranteeing the cooling effect of the coolant on the base body 1, and further guaranteeing the cooling effect on the nut. The multiple first heat exchange channels 2 and multiple second heat exchange channels 3 can be interconnected. The second heat exchange channels 3 and first heat exchange channels 2 can be connected in a one-to-one correspondence, i.e., one first heat exchange channel 2 is connected to only one second heat exchange channel 3, or one first heat exchange channel 2 can be connected to multiple second heat exchange channels 3 simultaneously, and vice versa. As described above, a third heat exchange channel 4 can also be provided inside the base body 1. Multiple third heat exchange channels 4 can also be provided. The third heat exchange channel 4 can be connected to multiple first heat exchange channels 2 and multiple second heat exchange channels 3 at the same time.

[0036] In this application, the connection method of the multiple first heat exchange channels 2, multiple second heat exchange channels 3, and multiple third heat exchange channels 4 is not limited, as long as it can ensure that the coolant can enter the base body 1 and that the base body 1 can fully absorb heat and flow out of the base body 1 after heat absorption. When setting the first heat exchange channels 2, second heat exchange channels 3, and third heat exchange channels 4, while ensuring connectivity, they can be spatially staggered. Here, "space" refers to the internal space of the base body 1, so that the heat exchange channels cover the base body 1 as much as possible, thereby increasing the temperature regulation effect on the base body 1.

[0037] The base body 1 may also have mounting holes 5 for installing threaded nuts. The mounting holes 5 have notches 6 extending axially and radially along their walls. The mounting holes 5 can be interference-fitted with the threaded nuts to ensure their installation strength and prevent displacement or movement during use. Simultaneously, the notches 6 on the walls of the mounting holes 5, while ensuring installation strength, also facilitate the installation of the threaded nuts. During installation, the mounting holes 5 have more space to deform, thus aiding in the installation of the threaded nuts.

[0038] An elastic contact 7 can also be provided on the wall of the mounting hole 5. The elastic contact 7 ensures that the outer periphery of the nut will not collide with the wall of the mounting hole 5 during use and be damaged, thus further ensuring the service life of the nut. At the same time, the elastic contact 7 can also act as a buffer, reducing the vibration between the nut and the base body 1 and ensuring the stability of the nut's position.

[0039] An insulation layer can also be provided on the outer surface of the base body 1. In this way, when the base body 1 is cooled down by the coolant, the insulation layer can minimize the loss of internal temperature, allowing the base body 1 to maintain a lower temperature for a longer period, further ensuring the cooling effect on the nut. Furthermore, the temperature of the external air will not affect the base body 1, as the insulation layer prevents the base body 1 from rapidly heating up due to external environmental influences after cooling.

[0040] The base body 1 may also include a controller 9, a first temperature sensor 91, and a second temperature sensor 92. The first temperature sensor 91 is used to detect the liquid temperature in the first heat exchange channel 2, and the second temperature sensor 92 is used to detect the liquid temperature in the second heat exchange channel 3. The controller 9 adjusts the temperature of the heat exchange medium based on the detection values ​​of the first temperature sensor 91 and the second temperature sensor 92. See details for further information. Figure 6 ,exist Figure 6 In the diagram, solid lines represent the flow of the cooling medium, and dashed lines represent signal transmission. A first temperature sensor 91 can be installed at the inlet 21 of the first heat exchange channel 2, and a second temperature sensor 92 can be installed at the outlet 31 of the second heat exchange channel 3. Thus, by using the first and second temperature sensors 91 and 92, the temperature of the coolant in the first heat exchange channel 2 and the second heat exchange channel 3 can be obtained, allowing for the assessment of the coolant's cooling effect on the base body 1. Furthermore, based on the data detected by the first and second temperature sensors 91 and 92, operators can adjust the coolant temperature via the controller 9 to further ensure the effective cooling of the base body 1. For example, when the first temperature sensor 91 detects that the liquid temperature in the first heat exchange channel 2 is high, it indicates that the coolant temperature is high and the heat absorption capacity is poor. At this time, the controller 9 can reduce the temperature of the coolant entering the first heat exchange channel 2. At the same time, when the second temperature sensor 92 detects that the liquid temperature in the second heat exchange channel 3 is low, it indicates that the coolant has not absorbed enough heat in the base body 1. At this time, the controller 9 can reduce the flow rate of the coolant so that the coolant can absorb enough heat in the base body 1.
