Description

Auxiliary device for providing temperature adjustment effect to machine tool components

This creation is related to the temperature control technology of the machine tool, and particularly refers to an auxiliary device that provides the effect of raising and lowering the temperature of the components of the machine tool.

The existing known technology for cooling the machine tool mainly uses a storage tank to contain the cooling liquid, and the storage tank is cooled by a cooling device, so that the cooled coolant flows to the machine tool to cool down .

The Republic of China Patent No. I593501 discloses a constant temperature control system for a machine tool and a flow path switching valve, which are mainly used to adjust the temperature of a machine tool during operation, thereby improving the machining accuracy and quality of the machine tool. The main technical means to achieve the above functions is to use its storage tank, pump, cooling device and flow path switching valve to provide cooling effect, and in terms of heating, it is additionally provided with a temperature sensor and heating device.

Although the aforementioned known technology uses a cooling device and a heating device to cool and heat the liquid in the storage tank, the coolant is pumped into the container of the machine tool by means of a pump to adjust the operation of the machine tool. The temperature, however, is not so easy to achieve temperature control in actual operation. Because, whether it is heating or cooling, it flows back to the storage tank after cooling or directly heats in the storage tank. However, the amount of liquid in the storage tank is much larger than the amount of liquid in the pipeline. Therefore, heating Or after the cooled liquid flows back into the storage tank, the impact on the temperature of the liquid in the entire storage tank is very limited. Further, whether it is heating or cooling, the liquid in the entire storage tank must be heated or cooled. It takes a lot of time and a lot of power. In this way, it cannot provide rapid heating or cooling requirements, and only slowly wait for the liquid in its storage tank to warm up or cool down before you can use the machine. Produces effective temperature adjustment effects. In addition, the aforementioned technology also needs to modify the cooling device originally matched with the machine tool in order to work effectively, and the modification changes the original structure, and this situation is also prone to failure.

It can be seen that the aforementioned known technology has a problem that the temperature adjustment speed is extremely slow, and it is less applicable when the temperature adjustment speed is required. Moreover, there is a problem that the original cooling device or storage tank needs to be modified.

Judging from the aforementioned known technology, it has a problem that the temperature adjustment speed is very slow, and such a technology cannot meet the occasions where rapid temperature adjustment is required. In addition, the aforementioned temperature adjustment device must be retrofitted to the original cooling device or storage tank, and there will also be problems of increased costs due to the retrofit and possible failure after the retrofit.

Based on the above description, this creation proposes an auxiliary device that provides the effect of adjusting the temperature of the components of the machine tool, which can provide a rapid heating effect when the temperature of the component of the machine tool is to be increased. The cooling device used.

In order to achieve the above effect, this creation proposes an auxiliary device that provides a temperature adjustment effect to a component of a machine tool, which is mainly used to connect the pipeline between a component of a machine tool and a cooling device. The auxiliary device includes: a return flow The liquid enters the channel, and one end of the liquid for returning from the component of the machine tool enters through the aforementioned pipe; an electric return valve is connected to the other end of the returning liquid entry channel, and is connected to the aforementioned pipe to allow the liquid to flow The cooling device; a hydrothermal circulation channel, one end of which is connected to the return liquid electric control valve; a source selection valve, which is connected to the other end of the hydrothermal circulation channel, and the liquid for the cooling device enters through the aforementioned pipeline; a One end of the liquid outlet channel is connected to the source selection valve, and the other end is for the liquid to flow out to the component of the machine tool through the aforementioned pipeline; and a pump is provided in the hot liquid circulation channel, the return liquid inlet channel and the liquid outlet One of the three channels is controlled by a control source to drive the liquid in the channel provided by the pump; wherein the control source controls the backflow The electric control valve and the source selection valve are used to switch the liquid flow direction. When the control source controls the return liquid electric control valve to switch to allow the liquid in the return liquid channel to flow to the cooling device, the control source also controls the source selection valve to switch. In order to allow the liquid of the cooling device to flow to the liquid outlet channel, at this time, the return liquid electric control valve system does not allow liquid to flow to the hot liquid circulation channel, and the source selection valve does not allow liquid in the hot liquid circulation channel. The inflow, the control source also controls the pump not to start; wherein, when the control source controls the return liquid electric control valve to switch to allow the liquid in the return liquid channel to flow to the hydrothermal circulation channel, the control source also controls the The source selection valve is switched so that the liquid in the hydrothermal circulation channel flows to the liquid discharge channel. At this time, the return liquid electric control valve system does not allow liquid to flow to the cooling device, and the source selection valve does not allow the cooling device. As the liquid flows in, the control source controls the pump to start.

With this, this creation can provide a rapid heating effect when the temperature of the components of the machine tool is to be raised. In addition, the first embodiment only needs to be installed between the component of the machine tool and the cooling device, and there is no need to modify the cooling device originally used by the machine tool.

In order to explain the technical characteristics of this creation in detail, the following preferred embodiments are illustrated in conjunction with the drawings as follows, where:

As shown in FIG. 1 and FIG. 2, an auxiliary device 10 for providing a temperature adjustment effect to a component of a machine tool, which is proposed in the first preferred embodiment of the present invention, is mainly used to connect a component of a machine tool and a cooling device. In the first embodiment, the component of the machine tool is a machine tool spindle 81, and the machine tool spindle 81 will be mainly described below. The auxiliary device 10 is mainly composed of a return liquid inlet channel 11, a return liquid electronic control valve 15, a hydrothermal circulation channel 21, a source selection valve 25, a liquid outlet channel 31, and a pump 35, of which:

The return liquid enters the channel 11, and one end of the liquid for returning from the machine tool main shaft 81 enters through the aforementioned pipeline.

The return liquid electric control valve 15 is connected to the other end of the return liquid inlet passage 11 and connected to the aforementioned pipeline so that liquid can flow to the cooling device 91. In the first embodiment, the return liquid electric control valve 15 is a three-way solenoid valve.

One end of the hydrothermal circulation channel 21 is connected to the return liquid electric control valve 15.

The source selection valve 25 is connected to the other end of the hydrothermal circulation channel 21, and the liquid for the cooling device 91 enters through the aforementioned pipeline. In the first embodiment, the source selection valve 25 is a three-way solenoid valve.

One end of the liquid outlet passage 31 is connected to the source selection valve 25, and the other end is for liquid to flow out to the machine tool main shaft 81 through the aforementioned pipeline.

The pump 35 is provided in the hydrothermal circulation channel 21 and is controlled by a control source 51 to drive the liquid in the hydrothermal circulation channel 21 to the source selection valve 25. In the first embodiment, the control source 51 is a microcomputer, and is electrically connected to the return liquid electric control valve 15, the source selection valve 25 and the pump 35.

The control source 51 controls the return liquid electric control valve 15 and the source selection valve 25 to switch the liquid flow direction. When the control source 51 controls the return liquid electric control valve 15 to switch to allow the liquid of the return liquid into the passage 11 to flow to the cooling device 91, the control source 51 also controls the source selection valve 25 to switch to let the cooling device 91 The liquid flows to the liquid outlet channel 31. At this time, the return liquid electric control valve 15 does not allow liquid to flow to the hydrothermal circulation channel 21, and the source selection valve 25 does not allow liquid to flow into the hydrothermal circulation channel 21. The control source 51 also controls the pump 35 not to start.

Wherein, when the control source 51 controls the return liquid electric control valve 15 to switch to allow the liquid of the return liquid into the channel 11 to flow to the hydrothermal circulation channel 21, the control source 51 also controls the source selection valve 25 to switch to the heat The liquid in the liquid circulation passage 21 flows to the liquid discharge passage 31. At this time, the return liquid electric control valve 15 does not allow liquid to flow to the cooling device 91, and the source selection valve 25 does not allow liquid to flow into the cooling device 91. The control source 51 controls the pump 35 to start.

In addition, in the first embodiment, there is also a liquid inlet channel 251 and a return liquid release channel 151. One end of the liquid inlet channel 251 is connected to the source selection valve 25, so that the liquid of the cooling device 91 enters first. After the liquid inlet passage 251, it enters the source selection valve 25 again. One end of the return liquid release channel 151 is connected to the return liquid electric control valve 15 for the liquid flowing out of the return liquid electronic control valve 15 to enter the return liquid release channel 151 before flowing to the cooling.装置 91。 Device 91.

In addition, in the first embodiment, there is also a heater 38 and a temperature sensor 39. The heater 38 is electrically connected to the control source 51, and the heater 38 is disposed in the liquid outlet channel 31. In addition, the temperature sensor 39 is disposed in the return liquid inlet channel 11 and is electrically connected to the control source 51.

The configuration of the first embodiment has been described above, and the operation of the first embodiment will be described next.

As shown in FIG. 3, before use, the auxiliary device 10 of this creation is first installed on a pipeline between a machine tool main shaft 81 and a cooling device 91. Between the main shaft 81 and the cooling device 91, a conveying pipe and a return pipe are usually used as a circulation path for the return and return of the cooling liquid (hereinafter referred to as a liquid), and the cooling device 91 itself has a water storage tank, a cooler, and The driving device for driving the liquid, so that it can be independently operated for cooling. When installing this creation, you can cut the delivery pipe and the return pipe, and connect this creation to the cut mouth of the two pipes, or directly replace the cut old pipe with a new pipe to connect. In the first embodiment, a new pipe installation is taken as an example. After installation, the liquid outlet 92 of the cooling device 91 is connected to the liquid inlet channel 251 through a pipe body 99, and the liquid outlet channel 31 is connected to the liquid inlet of the machine tool spindle 81 through a pipe body 99. In addition, the liquid outlet 83 of the machine tool spindle 81 is also connected to the return liquid inlet channel 11 through a pipe body 99, and the return liquid release channel 151 is connected to the cooling device through a pipe body 99 91 的 流 口 93。 The return port 91. The liquid inlet channel 251, the liquid outlet channel 31, the reflux liquid inlet channel 11, the reflux liquid release channel 151, the hydrothermal circulation channel 21, and the machine tool spindle 81 are all filled with liquid.

As shown in FIG. 4 and FIG. 5, during use, it is divided into heating and cooling operations. As shown in FIG. 4, during the cooling operation, the user can give an instruction to the control source 51 (ie, a microcomputer) to perform a cooling operation. At this time, the control source 51 controls the source selection valve 25 to switch to The liquid of the cooling device 91 flows to the liquid outlet channel 31, and the return valve liquid control valve 15 is controlled to switch the liquid of the return liquid into the channel 11 to the cooling device 91. In addition, the return liquid electric control valve 15 does not allow liquid to flow into the hydrothermal circulation passage 21, and the source selection valve 25 does not allow liquid in the hydrothermal circulation passage 21 to flow in. In this cooling operation, the control source 51 also controls the pump 35 not to start. In this way, the liquid of the cooling device 91 can enter through the liquid inlet channel 251, and then enter the machine tool spindle 81 through the source selection valve 25 and the liquid outlet channel 31 to cool down the temperature; and the liquid is in the tool After the machine spindle 81 absorbs heat, it flows out of the machine tool spindle 81 and enters the return liquid inlet channel 11, and then flows back to the cooling device 91 through the return liquid electronic control valve 15 and the return liquid release channel 151. in. From this, it can be known that during the cooling, the present invention only passes the liquid provided by the original cooling device 91 to form the same cooling circulation path as the conventional cooling device 91 to cool the machine tool spindle 81.

As shown in FIG. 5, during the temperature increasing operation, the user can give an instruction to the control source 51 to perform the temperature increasing operation. At this time, the control source 51 controls the return liquid electric control valve 15 to switch to allow the return The liquid entering the channel 11 flows to the hydrothermal circulation channel 21, and the control source 51 also controls the source selection valve 25 to switch to the liquid in the hydrothermal circulation channel 21 to flow to the liquid outlet channel 31. At the same time, the return liquid electric control valve 15 does not allow liquid to flow to the cooling device 91, and the source selection valve 25 does not allow liquid to flow into the cooling device 91. In this temperature increasing operation, the control source 51 controls the pump 35 to start. In this way, the liquid flowing out of the liquid outlet 92 of the cooling device 91 after entering the liquid inlet passage 251 will be blocked by the source selection valve 25 and will not enter the source selection valve 25 Moreover, the liquid of the return liquid entering the channel 11 cannot flow to the cooling device 91 because of the switching of the return liquid electric control valve 15. When the pump 35 is operated, the liquid in the hydrothermal circulation channel 21 is driven to the source selection valve 25 and flows to the liquid outlet channel 31. The control source 51 is measured by the temperature sensor 39 The temperature of the heater 38 is used to control the heater 38 to heat the liquid in the liquid discharge channel 31. The heated liquid then flows into the machine tool spindle 81 to provide a heating effect. The reflux liquid enters the channel 11, and then flows back into the hydrothermal circulation channel 21 through the reflux liquid electric control valve 15. That is, the heated liquid does not return to the cooling device 91, but circulates between the machine tool spindle 81, the return liquid inlet channel 11, the hydrothermal circulation channel 21, and the liquid outlet channel 31, and At the same time, it is heated by the heater 38 to raise the temperature. Because the amount of liquid in this cycle is far less than the amount of liquid in the cooling device 91, it can be easily heated to increase the temperature and achieve rapid heating of the machine tool spindle 81. Effect.

As can be seen from the above, this creation can provide an additional heating function for the spindle of a machine tool that has a cooling device 91, and still retain its original cooling function. It is an auxiliary device that can provide a temperature adjustment effect to the spindle of the machine tool. 10. When the temperature is lowered, the cooling liquid provided by the cooling device 91 is passed to directly cool the machine tool spindle 81. When the temperature is increased, the flow path is switched so that the cooling liquid of the cooling device 91 is blocked in the cooling device 91. Outside of creation 10, it cannot flow to the machine tool spindle 81, and the liquid flowing out of the machine tool spindle 81 forms an independent circulation channel, and at the same time, the liquid in this independent circulation channel is heated to achieve the effect of rapid heating and temperature rise.

As shown in FIG. 3, it should be noted that, in a general machine tool, the components on the machine tool to be cooled are usually a plurality of devices such as a machine tool spindle 81, a motor, and a hollow screw. The pipeline is divided to provide the coolant and circulate it. Therefore, even if the auxiliary device 10 of the present invention is installed on the pipeline between the machine tool spindle 81 and the cooling device 91, the cooling device 91 is blocked during the heating operation. Cooling liquid. This blocking does not cause the cooling device 91 to completely fail to output the cooling liquid, and the cooling liquid output by it will still flow to other devices for cooling through its pipeline. It can be understood here that although in the first embodiment, the components of the machine tool are described using the machine tool spindle 81 as an example, however, the components of the machine tool that need to be temperature-adjusted can also be changed to motors or hollow The screw is not limited to the machine tool spindle 81.

As shown in FIG. 6 again, under special conditions, if the cooling liquid output by the cooling device 91 is only used to dissipate heat from the spindle 81 of the machine tool, when the original installation is installed, the control The source 51 must turn off the cooling device 91 at the same time to prevent the cooling device 91 from malfunctioning because the cooling liquid is blocked.

To sum up, it can be known that the first embodiment can provide a rapid heating effect when the temperature of the machine tool main shaft 81 is to be raised. In addition, the first embodiment only needs to be installed in the pipeline between the machine tool main shaft 81 and the cooling device 91, and there is no need to modify the cooling device originally used with the machine tool.

It should be noted that, referring to FIG. 7 and FIG. 8 again, in addition to the position of the heater 38 disclosed in the liquid outlet channel 31, as shown in FIG. The circulation channel 21, or as shown in FIG. 8, may also be provided in the return liquid inlet channel 11, but the preferred position is that the heater 38 is located behind the temperature sensor 39 as viewed from the direction of the liquid flow. That is, the liquid first flows through the temperature sensor 39 to sense the temperature, and then flows through the heater 38 for heating. Such a setting method can ensure that during the aforementioned heating operation, the liquid flowing out of the machine tool spindle 81 is first sensed by the temperature sensor 39 and then heated by the heater 38. Because the heater 38 heats the liquid in advance, the measurement of the temperature of the liquid flowing from the machine tool spindle 81 is inaccurate. In addition, two or more heaters 38 may be provided, and the heaters may be provided in the positions described above.

In addition, the pump 35 may be provided in the hot liquid circulation channel 21 or in the reflux liquid inlet channel 11 or the liquid outlet channel 31. During the heating operation, after the flow path is switched, the pump 35 can drive the liquid to the machine tool spindle 81, whether it is set in the hydrothermal circulation channel 21, the return liquid inlet channel 11 or the liquid outlet channel 31. The reflux liquid circulates between the passage 11, the hydrothermal circulation passage 21, and the liquid discharge passage 31. This way of setting can be understood directly, and the contents are no longer represented by diagrams.

As shown in FIG. 9, an auxiliary device 10 ′ for providing a temperature adjustment effect to a component of a machine tool is proposed in the second preferred embodiment of the present invention. The auxiliary device 10 ′ is mainly similar to the first embodiment disclosed above, except that:

In the second embodiment, the liquid inlet channel and the return liquid release channel are not provided. Instead, the source selection valve 25 ′ and the return liquid electric control valve 15 ′ are directly connected to the cooling device 91 through a pipe body 99. .

The control source 51 ′ may be an external control box, for example, the control box of the machine tool itself, and is electrically connected to the return liquid electric control valve 15 ′, the source selection valve 25 ′, and the pump 35 by wires. '. That is, the control source 51 'of this creation may be a control box of the machine tool itself or other externally available control devices.

In the second embodiment, there is also a flow sensor 41 ', and the flow sensor 41' is electrically connected to the control source 51 '. Thereby, the control source 51 ′ can detect whether the liquid in the hydrothermal circulation channel 21 ′ is flowing through the flow sensor 41 ′, thereby confirming that the pump 35 ′ is operating normally during the temperature rising operation. of.

In addition, the heater and the temperature sensor are not provided in the second embodiment. In the temperature increasing operation, the heat generated by the operation of the machine tool spindle 81 is mainly used for heating, and the flow direction of the liquid is controlled by the control source 51 ′, so that the liquid flowing out of the machine tool spindle 81 is only used for heating. It can flow back to the machine tool spindle 81 through the return liquid entering the channel 11 ', the hydrothermal circulation channel 21', and the liquid discharge channel 31 ', and the machine tool spindle 81 itself is used during the operation by this cycle The generated thermal energy provides a warming effect. Although this heating effect is slower than using a heater, it is still faster than the conventional method of heating the entire water storage tank. As for the temperature sensing part, although the temperature sensor is omitted in the second embodiment, the external control source 51 ′ can still obtain the temperature of the machine tool spindle 81 through the temperature sensor of the machine tool itself. Numerical value, and then perform corresponding operations or reactions.

It should also be noted that in the second embodiment, the components of the machine tool are still described by taking the machine tool spindle 81 as an example. However, the components of the machine tool that need to be adjusted in temperature can also be changed to motors or The hollow screw is not limited to the machine tool spindle 81.

In the second embodiment, the use of the external control source 51 'can increase the openness of the control of this creation, so that manufacturers have more choices.

The rest of the structure and the effects that can be achieved in this second embodiment are the same as those in the first embodiment, and will not be described again.
