In the first embodiment, the machine tool spindle 81 is taken as an example. The machine tool spindle 8181 is mainly used below. To explain. The auxiliary device 10 that provides the effect of adjusting the temperature of the components of the machine tool is mainly composed of a delivery channel 11, a return channel 13, a cold liquid shortcut channel 15, a hot liquid shortcut channel 17, a cold liquid shortcut valve 19, and a hot liquid It consists of a shortcut valve 21, a delivery valve 23, a return valve 25 and a pump 27, of which:

The hydrothermal shortcut valve 21 is arranged in the hydrothermal shortcut channel 17.

The delivery valve 23 is disposed in the delivery channel 11 and is located between the location where the cold liquid shortcut channel 15 is connected to the delivery channel 11 and the location where the hot liquid shortcut channel 17 is connected to the delivery channel 11.

The return valve 25 is arranged in the return passage 13 and is located between the position where the cold liquid shortcut passage 15 is connected to the return passage 13 and the position where the hot liquid shortcut passage 17 is connected to the return passage 13.

The pump 27 is arranged in the hydrothermal shortcut channel 17. The pump 27 is controlled by a control source 31 to drive the cooling liquid in the hot liquid shortcut channel 17 to move to the delivery channel 11.

In the first embodiment, the control source 31 is a microcomputer in the first embodiment, which is electrically connected to the pump 27, the cold liquid shortcut valve 19, the hot liquid shortcut valve 21, and the delivery valve 23 and the return valve 25. The cold liquid shortcut valve 19, the hot liquid shortcut valve 21, the sending valve 23, and the return valve 25 are all opened or closed under the control of the control source 31, so as to make the passages or breaks provided for cooling. Liquid may or may not flow through. In addition, the cold-liquid shortcut valve 19, the hot-liquid shortcut valve 21, the delivery valve 23, and the return valve 25 can be implemented using single-way electronically controlled valves, and their settings can be opened or closed in a simple open and closed state. The channel flow path.

The control source 31 is for operation to switch between a cooling mode and a circulation mode. When switching to the cooling mode, it controls the cold liquid shortcut valve 19 and the hot liquid shortcut valve 21 to close, and controls the delivery valve 23 And the return valve 25 is opened, and the pump 27 is controlled to be closed; when the control source 31 is switched to the circulation mode, the cold liquid shortcut valve 19 and the hot liquid shortcut valve 21 are controlled to open, and the delivery valve 23 and The return valve 25 is closed.

The structure 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 present invention is installed on the pipeline between a machine tool spindle 81 and a cooling device 91. Because of the conventional machine tool with a cooling device 91, the main shaft 81 of the machine tool and the cooling device 91 are usually connected by a pipe as a circulation channel for the cooling liquid to go and return, and the cooling device 91 itself has a storage tank. The water tank, the condensing compressor, and the driving device for driving the coolant, therefore, can operate independently to cool the main shaft 81 of the machine tool. When the present invention is installed, the aforementioned pipe body can be cut open, and the present invention can be connected to the cutouts of these pipe bodies, or the original pipe body can be replaced with a new pipe for connection. In the first embodiment, Take the installation of new pipes as an example. After installation, the liquid outlet 92 of the cooling device 91 is connected to one end of the sending channel 11 through a tube body 99, and the other end of the sending channel 11 is also connected to the machine tool through a tube body 99 The liquid inlet 83 of the main shaft 81; in addition, the liquid outlet 82 of the machine tool main shaft 81 is also connected to one end of the return channel 13 by a tube body 99, and the other end of the return channel 13 is also connected by a tube The body 99 is connected to the return port 93 of the cooling device 91. Wherein, each of the tube body 99, the delivery channel 11, the return channel 13, the cold liquid shortcut channel 15, and the hot liquid shortcut channel 17 are all filled with cooling liquid.

During operation, the control source 31 can be operated to switch between a cooling mode or a circulation mode.

As shown in Figure 4, when the control source 31 is switched to the cooling mode, the control source 31 controls the cold liquid shortcut valve 19 and the hot liquid shortcut valve 21 to close, and controls the delivery valve 23 and the return valve 25 to open . In this way, the cooling liquid flowing out of the liquid outlet 92 of the cooling device 91 enters the delivery channel 11, passes through the delivery valve 23, and flows to the machine tool spindle 81, thereby providing a cooling effect. After the cooling liquid absorbs heat in the main shaft 81 of the machine tool, it flows out from the liquid outlet 82 of the main shaft 81 of the machine tool, enters the return passage 13, and flows back into the cooling device 91 through the return valve 25. Since the cold liquid shortcut valve 19 and the hot liquid shortcut valve 21 are closed, the cooling liquid will not flow through the cold liquid shortcut channel 15 and the hot liquid shortcut channel 17. In addition, since the pump 27 is closed, Therefore, the cooling liquid in the hot liquid shortcut channel 17 will not be driven to move. It can be seen from this that during cooling, the present invention only allows the cooling liquid provided by the original cooling device 91 to pass through, and forms the same cooling path as the conventional cooling device 91 to cool the machine tool spindle 81.

As shown in FIG. 5, when the control source 31 is switched to the circulation mode, the control source 31 controls the cold liquid shortcut valve 19 and the hot liquid shortcut valve 21 to open, and controls the delivery valve 23 and the return valve 25 to close . In this way, the cooling liquid flowing out of the liquid outlet 92 of the cooling device 91 enters the sending channel 11, but because the sending valve 23 is closed and the cooling liquid shortcut valve 19 is opened, the cooling liquid enters the sending channel 11 The cooling liquid is forced to flow into the cooling liquid shortcut channel 15 and then into the return channel 13. Since the return valve 25 is closed, the cooling liquid flows back to the cooling device 91. On the other hand, the user can control the pump 27 to turn on or off according to the situation. If the pump 27 is controlled to turn on, the cooling in the hydrothermal shortcut channel 17 is driven to flow into the delivery channel 11, but due to the delivery The valve 23 is closed, so the coolant is forced to flow to the machine tool spindle 81, and then enters the return channel 13, and then is forced to flow back to the hot liquid shortcut channel 17 due to the closure of the return valve 25, in a circulating state; and If the pump 27 is turned off, the coolant in the hot liquid shortcut channel 17, the delivery channel 11, the machine tool main shaft 81 and the return channel 13 will not flow, and the machine tool main shaft 81 will not be cooled down. This non-cooling effect can also cause the temperature of the machine tool spindle 81 to stop running to slowly drop the temperature, showing an effect similar to maintaining the temperature, or the temperature rise due to the continuous operation of the machine tool spindle 81 to show a temperature rising state. It can be seen from the above that when the control source 31 is switched to the circulation mode, the cooling liquid sent by the cooling device 91 is directly returned to the cooling device 91 through the cooling liquid shortcut channel 15 and therefore cannot be supplied to the machine tool spindle 81 , So as to provide a temperature increase or similar effect to the machine tool spindle 81.

It should be additionally noted that when the control source 31 is switched to the circulating state, the flow direction of the cooling liquid driven by the pump 27 does not need to be particularly limited. It is preferable to drive the cooling liquid to flow out from the hot liquid shortcut channel 17 Channel 11, but if the driving direction is changed to drive the cooling liquid to flow from the hot liquid shortcut channel 17 to the return channel 13 is also possible.

It can be seen from the above that the present invention can provide an additional temperature holding function for the machine tool components that originally have a cooling device 91, while still retaining its original cooling and cooling function, and is an auxiliary that can provide the effect of adjusting the temperature. Device. By switching the flow path, the cooling liquid sent by the cooling device 91 can/cannot reach the components of the machine tool, so as to achieve the effect of adjusting the temperature of the tool mechanism. In addition, each of the valves of the present invention is arranged on the channel, instead of being arranged at the place where the channel pipes are connected, and it can still achieve the effect of raising temperature or similar temperature holding when the temperature of the components of the machine tool is to be increased, and , There is no need to modify the cooling device 91 originally used with the machine tool.

As shown in Figs. 6-7, the second preferred embodiment of the present invention proposes an auxiliary device 10' for adjusting the temperature of the components of the machine tool, which is basically the same as the first embodiment disclosed above, and the difference lies in:

The pump 27' is arranged in the delivery channel 11' and is located between the position where the hydrothermal shortcut channel 17' is connected to the delivery channel 11' and the main shaft 81' of the machine tool.

The control source 31' is an external control box, such as the control box of the machine tool itself, which is electrically connected to the pump 27', the cold liquid shortcut valve 19', the hot liquid shortcut valve 21', and the The delivery valve 23' and the return valve 25'.

In addition, the second embodiment also has a heater 41' and a temperature sensor 43', which are electrically connected to the control source 31'. The heater 41' is provided with a hydrothermal shortcut channel 17', which is controlled by the control source 31. 'Control to provide a heating effect, the temperature sensor 43' is arranged in the return channel 13' and is located between the position where the hydrothermal shortcut channel connection 17' is connected to the return channel 13' and the main shaft 81' of the machine tool, And it is electrically connected to the control source 31' for sensing temperature.

Moreover, in the second embodiment, the cold liquid shortcut channel 15' and the hot liquid shortcut channel 17' are respectively provided with a flow sensor 45', and each of the flow sensors 45' is electrically connected to the control The source 31' is mainly used to detect the flow state of the coolant in the aforementioned flow channel.

It should be additionally noted that the pump 27' can also be arranged in the return channel 13' between the position where the hot liquid shortcut channel 17' is connected to the return channel 13' and the main shaft 81' of the machine tool. The temperature sensor 43' can also be arranged in the delivery channel 11' and located between the position where the hydrothermal shortcut channel 17' is connected to the delivery channel 11' and the main shaft 81' of the machine tool, or the return channel 13' The position between the position where the hydrothermal shortcut passage 17' is connected to the return passage 13' and the main shaft 81' of the machine tool is not limited by the aforementioned position.

When the second embodiment is in operation, when the control source 31' is switched to the cooling mode, the pump 27' is controlled to be turned off, and the heater 41' is also turned off at this time, so that the coolant can be used for the spindle of the machine tool. 81' performs a cooling action. When the control source 31' is switched to the circulation mode, the pump 27' can be controlled to start to drive the cooling liquid to move. No matter where the pump 27' is set in any of the above positions, the cooling liquid can be driven to move. Circulate between the hot liquid shortcut channel 17' and the machine tool spindle 81'. At this time, the heater 41' is also controlled to start, so as to heat the coolant, thereby accelerating the rate of temperature rise. The temperature sensor 43' is used to sense the heating state of the cooling liquid, and the control source 31' can thereby determine whether to turn off the heater 41'. Each of the flow sensors 45' is used to allow the control source 31' to determine whether the liquid in the hot liquid shortcut channel 17' and the cold liquid shortcut channel 15' is normally flowing in the circulation mode.

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