This creation is related to the temperature control technology of the machine tool, especially refers to an auxiliary device that provides a cooling or holding temperature effect on the components of the machine tool.

The existing 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 cooling fluid flows to the machine tool to lower the temperature .

The Republic of China Announcement Patent No. M584230 discloses an auxiliary device that provides a temperature adjustment effect on the components of the machine tool. It mainly uses two three-way electronic control valves to control the flow of the coolant, and changes the cooling by switching to the cooling operation. The flow direction of the liquid is to use the cooling liquid to cool, or switch to a temperature increase operation to change the flow direction of the cooling liquid, so that the cooling liquid does not flow back to the cooling device, and the pump is used to drive the cooling liquid between the auxiliary device and the machine tool. Circulate between components, thereby achieving the effect of heating.

However, the author of this case found that for the components of the machine tool, in actual operation, after the temperature rise of the components of the machine tool is completed, as long as the cooling is not performed, the temperature of the components of the machine tool decreases in the state of natural cooling Very slow, that is, if the machine tool needs to stop the machining operation for a short time due to the replacement of the workpiece during the machining process, the machine tool components do not need to be continuously heated during this short time to be maintained at a certain level. Temperature, this technical concept was not put forward in the aforementioned case.

Based on the currently known technology, there is no technical concept of cooling and holding the temperature of the components of the machine tool. In this case, an auxiliary device that provides a cooling or holding temperature effect on the components of the machine tool is proposed, which differs in technical characteristics The aforementioned known technology can also achieve the effect of providing cooling and holding temperature to the components of the machine tool.

Based on the above, the author proposes an auxiliary device that provides a cooling or holding effect on the components of the machine tool, which is mainly used to connect the pipeline between the components of a machine tool and a cooling device. Auxiliary devices for temperature holding effect include: a delivery channel, one end of which is connected to the aforementioned pipeline for the inflow of the cooling fluid sent by the cooling device, and the other end is connected to the aforementioned pipeline for the outflow of the cooling fluid into the tool The components of the machine; a return channel, one end of which is supplied with the cooling fluid returning from the components of the machine tool through the aforementioned pipeline, and the other end is connected to the aforementioned pipeline for the cooling fluid to flow to the cooling device; a shortcut channel, which One end is connected to the delivery channel to communicate with it, the other end is connected to the return channel to communicate with it; a circulation valve is provided in the shortcut channel, and is electrically connected to a control source, and the circulation valve is controlled by the control source Opening/closing, when the circulation valve is opened, the shortcut channel allows the coolant to pass through, and when the circulation valve is closed, the shortcut channel is closed to allow the coolant to pass through; and a channel valve is provided at the delivery Channel, and is located between the position where the shortcut channel is connected to the delivery channel and the component of the machine tool, or is provided in the return channel, and is located between the location where the shortcut channel is connected to the return channel and the component of the machine tool , The channel valve is electrically connected to the control source, and is opened/closed by the control source, when the channel valve is opened or closed, the delivery channel or the return channel channel is not or not; wherein, the control The source system is switched to the cooling mode or the circulation mode. When the control source is switched to the cooling mode, the control source system controls the circulation valve to close and the channel valve to open; when the control source is switched to the circulation mode, the control source system The circulation valve is controlled to open and the passage valve is closed.

In this way, through the cooperative opening or closing action of the control source, the channel valve and the circulation valve, the creation can achieve the effect of providing cooling and holding temperature to the components of the machine tool, and the technical characteristics are different from the foregoing prior art .

In order to explain the technical characteristics of this creation in detail, the following preferred embodiments are described below in conjunction with the schematic description, in which:

As shown in FIGS. 1 to 3, the present invention proposes a first preferred embodiment of an auxiliary device 10 that provides a cooling or holding temperature effect on a machine tool component, which is mainly used to connect a machine tool component 81 and a cooling device The pipeline between the devices 91, the auxiliary device 10 that provides a cooling or holding effect on the components of the machine tool is mainly composed of a sending channel 11, a return channel 13, a shortcut channel 15, a circulation valve 17 and a channel valve 19 Composed of:

One end of the delivery channel 11 is connected to the aforementioned pipeline for the inflow of the cooling fluid sent by the cooling device 91, and the other end is connected to the aforementioned pipeline for the outflow of the cooling fluid into the component 81 of the machine tool. The components of the machine tool may be a machine tool spindle, a hollow screw, or a servo motor. In this embodiment, the machine tool spindle is used as an example.

At one end of the return channel 13, the cooling fluid returned from the component 81 of the machine tool enters through the aforementioned pipeline, and the other end is connected to the aforementioned pipeline to allow the cooling fluid to flow to the cooling device 91.

One end of the shortcut channel 15 is connected to the delivery channel 11 to communicate with it, and the other end is connected to the return channel 13 to communicate with it.

The circulation valve 17 can be an electronically controlled one-way valve, which is provided in the shortcut channel 15 and is electrically connected to a control source 21. The circulation valve 17 is controlled by the control source 21 to open/close. When the circulation valve 17 is opened, the shortcut channel 15 allows the coolant to pass through. When the circulation valve 17 is closed, the shortcut channel 15 is closed to prevent the coolant from passing through.

The channel valve 19 can be an electrically controlled one-way valve, which is provided in the delivery channel 11 and is located between the position where the shortcut channel 15 is connected to the delivery channel 11 and the component 81 of the machine tool. The channel valve 19 is electrically connected to the control source 21 and is opened/closed by the control source 21. When the channel valve 19 is opened or closed, the delivery channel 11 is allowed to pass or not pass.

The above control source 21 is for the user to switch to the cooling mode or the circulation mode. When the control source 21 is switched to the cooling mode, the control source 21 controls the circulation valve 17 to close and the passage valve 19 to open; at the control source When 21 is switched to the circulation mode, the control source 21 controls the circulation valve 17 to open and the passage valve 19 to close. In addition, the above-mentioned control source 21 may be a microcomputer built into the auxiliary device of this creation, or it may be an external control box, such as the control box of the machine tool itself, which is electrically connected to the circulation valve 17 by wires And the passage valve 19. In this embodiment, a microcomputer is used as an example.

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

As shown in FIG. 3, before use, the auxiliary device 10 of the present invention is installed on the pipeline between the component 81 of a machine tool and a cooling device 91. Since a machine tool with a cooling device 91 is conventionally known, a conveying pipe and a return pipe are generally used as circulation channels for cooling liquid to go and return between the component 81 of the machine tool and the cooling device 91, and the cooling device 91 itself That is, it has a water storage tank, a cooling compressor, and a pump for driving liquid, so it can be operated independently for cooling. When installing this creation, you can cut the delivery pipe and the return pipe, and then connect this creation to the opening of the two pipes, or directly replace the cut pipe with a new pipe to connect. In the first embodiment, a new tube installation is taken as an example. After installation, the liquid outlet 93 of the cooling device 91 is connected to one end of the delivery channel 11 through a tube 99, and the other end is also connected to the liquid inlet of the component 81 of the machine tool through a tube 99 In addition, the liquid outlet 83 of the component 81 of the machine tool is also connected to one end of the return channel 13 by a tube 99, and the other end of the return channel 13 is connected to the end by a tube 99 The reflux port 92 of the cooling device 91. Wherein, the delivery channel 11, the return channel 13, the shortcut channel 15, each of the tube body 99 and the component 81 of the machine tool are filled with coolant.

As shown in Figures 4 to 5, in use, it is divided into cooling and holding operations. As shown in FIG. 4, when performing the cooling operation, the user can issue an instruction to the control source 21 (ie microcomputer) to switch it to the cooling mode, the control source 21 controls the circulation valve 17 to close and the passage valve 19 Open. At this time, the cooling fluid sent by the cooling device 91 will enter the sending channel 11 and flow to the component 81 of the machine tool, and the cooling fluid flowing out of the component 81 of the machine tool will enter the return channel 13 and return to The cooling device 91, because the circulation valve 17 is closed, the fluid will not flow through the shortcut channel 15 and enter the return channel 13. In this state, the cooling liquid of the cooling device 91 directly enters the component 81 of the machine tool to provide a cooling effect, so the component 81 of the machine tool can be effectively cooled.

As shown in FIG. 5, during the temperature holding operation, the user can issue an instruction to the control source 21 (ie microcomputer) to switch it to the circulation mode, the control source 21 controls the circulation valve 17 to open and the channel valve 19 closed. At this time, the cooling liquid sent by the cooling device 91 will enter the sending channel 11, but because the channel valve 19 is closed, it cannot flow to the component 81 of the machine tool, and because the circulation valve 17 is opened, the cooling channel 91 opens from the sending channel 11 flows into the shortcut channel 15, and then enters the return channel 13 to return to the cooling device 91. In this state, the cooling liquid of the cooling device 91 cannot enter the component 81 of the machine tool to provide a cooling effect, but only circulates between the cooling device 91 and the shortcut channel 15, so the machine tool The component 81 does not need to be cooled down quickly without new cooling liquid, but can be maintained at a certain temperature range and slowly and naturally cool down, so as to achieve a temperature holding effect that does not cool down quickly in a short time. In this state, since the shortcut channel 15 provides the effect of circulating the cooling fluid back, the cooling device 91 may not be shut down, and the internal pump may not need to be shut down, thereby reducing the number of times the cooling device 91 is switched on or off. Frequency, to avoid the problem of damage or failure that the cooling device 91 may encounter due to frequent switching on and off.

It can be seen from the above that this creation can provide the function of maintaining the temperature of the components of the machine tool that originally has the cooling device 91, and still retains its original cooling function, and provides a cooling or An auxiliary device for temperature holding effect, and the concept of temperature holding in this creation is not disclosed by the aforementioned known technology. In addition, in terms of cost, the cost of electronically controlled one-way valves is generally cheaper than that of three-way electronic valves. Therefore, the technology of this creation can also effectively reduce costs while still providing the effect of cooling or holding temperatures.

As shown in FIG. 6, the author proposes an auxiliary device 10' for providing a cooling or holding temperature effect on the components of the machine tool according to the second preferred embodiment, which is basically the same as the first embodiment disclosed above, except for:

The channel valve 19' is not provided in the delivery channel 11 as described in the first embodiment, but is provided in the return channel 13' in the second embodiment, and is located in the shortcut channel 15' connected to the Between the position of the return channel 13' and the component 81' of the machine tool.

The operation state of the second embodiment is explained as follows.

During the cooling operation, the influence of the passage valve 19' on the flow direction of the cooling liquid is the same as that of the first embodiment described above, which will not be repeated here. In the temperature-maintaining operation, the control source 21' controls the circulation valve 17' to open and the passage valve 19' to close. At this time, the cooling liquid sent by the cooling device 91' will enter the sending channel 11', but because the channel valve 19' is closed, the cooling liquid cannot flow back, which further causes the cooling liquid in the sending channel 11' Flow to the component 81' of the machine tool, and because the circulation valve 17' is opened, the cooling fluid can only flow from the delivery channel 11' into the shortcut channel 15', and then into the return channel 13' to return to the Cooling device 91'.

The remaining structures and the achievable effects of the second embodiment are the same as those of the first embodiment disclosed above, and will not be repeated here.
