Description

Auxiliary device for adjusting temperature effect for components of machine tool

The present invention is related to the temperature control technology of the machine tool, and particularly refers to an auxiliary device that provides a heating and cooling effect to the components of the machine tool.

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

The Republic of China Announcement No. I593501 patent discloses a machine tool thermostatic control system and a flow switching valve, which is mainly used to adjust the temperature of a machine tool during operation, so as to improve the machining accuracy and quality of the machine tool. Its main technical means to achieve the above-mentioned functions is to use its storage tank, pump, cooling device and flow path switching valve to provide a cooling effect, and in terms of heating, it is additionally equipped with a temperature sensor and a 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 cooling liquid is pumped into the container of the machine tool to adjust the operation time of the machine tool. However, in actual operation, it is not so easy to achieve temperature control. Because, whether it is heating or cooling, it flows back to the storage tank or directly heated in the storage tank after cooling. However, the amount of liquid in the storage tank is much greater than the amount of liquid in the pipeline, so heating Or after the cooled liquid flows back into the storage tank, the effect on the temperature of the liquid in the entire storage tank is very limited. Looking 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. As a result, it cannot provide rapid heating or cooling requirements, but can only slowly wait for the liquid in its storage tank to rise or cool down, and then the machine tool can be adjusted Produce effective temperature adjustment effect. In addition, the aforementioned technology needs to modify the original cooling device of the machine tool to work effectively, and the modification changes the original structure. This situation is also more prone to failure.

It can be seen that the aforementioned known technology has the problem of extremely slow temperature adjustment speed, which is less suitable for occasions where the temperature adjustment speed demand is high. There is also the need to modify the original cooling device or storage tank.

Judging from the aforementioned known technology, it has the problem that the temperature adjustment speed is very slow, and this technology cannot meet the occasions that require rapid temperature adjustment. In addition, the aforementioned temperature adjustment device must be retrofitted to the original cooling device or storage tank, and there are also problems of increased cost due to retrofitting and possible failure after retrofitting.

Based on the above description, the present invention proposes an auxiliary device that provides the temperature adjustment effect for the components of the machine tool, which can provide a rapid heating effect when the temperature of the components of the machine tool is to be increased. In addition, there is no need to modify the original machine tool. The cooling device used in conjunction.

In order to achieve the above effects, the present invention proposes an auxiliary device that provides temperature adjustment effects for components of a machine tool, which is mainly used to connect a 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 returned from the components of the machine tool enters through the aforementioned pipeline; a return fluid electronic control valve is connected to the other end of the return fluid inlet channel, and is connected to the aforementioned pipeline to allow the liquid to flow The cooling device; a hot liquid circulation channel, one end connected to the return liquid electronic control valve; a source selection valve, connected to the other end of the hot liquid circulation channel, and for the liquid of the cooling device to enter through the aforementioned pipeline; A liquid outlet channel, one end is connected to the source selection valve, and the other end is for the liquid to flow out to the machine tool component through the aforementioned pipeline; and a pump arranged 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 set by the pump to move; wherein the control source controls the return liquid electronic control valve and the source selection valve to switch the liquid flow direction, When the control source controls the return fluid electronic control valve to switch to allow the return fluid entering the channel to flow to the cooling device, the control source also controls the source selection valve to switch to allow the cooling device liquid to flow to the outlet channel, At this time, the return liquid electronic control valve system does not allow liquid to flow to the hydrothermal circulation channel, and the source selection valve does not allow liquid in the hydrothermal circulation channel to flow in, and the control source also controls the pump not to start; Wherein, when the control source controls the return fluid electronic control valve to switch to allow the fluid entering the channel of the return fluid to flow to the hydrothermal circulation channel, the control source also controls the source selection valve to switch to the liquid in the hydrothermal circulation channel Flow to the liquid outlet channel. At this time, the reflux electronic control valve system does not allow liquid to flow to the cooling device, and the source selection valve does not allow liquid to flow into the cooling device. The control source controls the pump to start.

Thereby, the present invention can provide the effect of rapid temperature rise when the temperature of the components of the machine tool is to be increased. In addition, the first embodiment only needs to install the pipeline between the components of the machine tool and the cooling device, and there is no need to modify the original cooling device used by the machine tool.

In order to explain in detail the technical features of the present invention, the following preferred embodiments are described in conjunction with the drawings, in which:

As shown in Figures 1 and 2, the first preferred embodiment of the present invention provides an auxiliary device 10 for adjusting the temperature of the components of a machine tool, which is mainly used to connect a component of a machine tool and a cooling device For the pipeline between 91, in the first embodiment, the machine tool main shaft 81 is taken as an example for the machine tool main shaft 81, and the machine tool main shaft 81 is mainly used for description 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, among which:

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

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

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

The source selection valve 25 is connected to the other end of the hot liquid circulation channel 21 and allows the liquid of the cooling device 91 to enter 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 channel 31 is connected to the source selection valve 25, and the other end allows liquid to flow out to the main shaft 81 of the machine tool through the aforementioned pipeline.

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

Wherein, the control source 51 controls the reflux liquid electronic control valve 15 and the source selection valve 25 to switch the liquid flow direction. When the control source 51 controls the reflux electronic control valve 15 to switch to allow the reflux liquid to enter the channel 11 to flow to the cooling device 91, the control source 51 also controls the source selection valve 25 to switch to the cooling device 91 The liquid flows to the outlet channel 31. At this time, the return liquid electronic control valve 15 does not allow liquid to flow to the hot liquid circulation channel 21, and the source selection valve 25 does not allow the liquid in the hot liquid circulation channel 21 to flow into , The control source 51 also controls the pump 35 not to start.

Wherein, when the control source 51 controls the reflux electronic control valve 15 to switch to allow the reflux liquid to enter 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 channel 21 flows to the liquid outlet channel 31. At this time, the return liquid electronically controlled valve 15 does not allow liquid to flow to the cooling device 91, and the source selection valve 25 does not allow liquid from the cooling device 91 to flow into , 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 reflux liquid release channel 151. One end of the liquid inlet channel 251 is connected to the source selection valve 25 to allow the liquid from the cooling device 91 to enter first After the liquid inlet channel 251, it then enters the source selection valve 25. One end of the reflux liquid release channel 151 is connected to the reflux liquid electronic control valve 15 for the liquid discharged from the reflux liquid electronic control valve 15 to first enter the reflux liquid release channel 151 and then flow 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 arranged in the return liquid inlet channel 11 and is electrically connected to the control source 51.

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

As shown in Figure 3, prior to use, the auxiliary device 10 of the present invention is installed on the pipeline between a machine tool spindle 81 and a cooling device 91. Since the conventional machine tool with a cooling device 91, the machine tool Between the main shaft 81 and the cooling device 91 is usually a conveying pipe and a return pipe as the circulating passage for the cooling liquid (hereinafter referred to as liquid), and the cooling device 91 itself has a water storage tank, a cooler and The driving device used to drive the liquid, therefore, it can operate independently for cooling. When the present invention is installed, the delivery pipe and the return pipe can be cut open, and the present invention can be connected to the cut-out nozzles of these 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 tube body 99, and the liquid outlet channel 31 is connected to the liquid inlet channel of the machine tool spindle 81 through a tube body 99 Port 82; In addition, the liquid outlet 83 of the machine tool spindle 81 is also connected to the reflux inlet channel 11 by a tube body 99, and the reflux liquid release channel 151 is connected to the cooling device by a tube body 99 91 of the return port 93. Wherein, the liquid inlet channel 251, the liquid outlet channel 31, the reflux liquid inlet channel 11, the reflux liquid release channel 151, the hot liquid circulation channel 21 and the machine tool spindle 81 are all filled with liquid.

As shown in Fig. 4 and Fig. 5, when in use, it is divided into heating and cooling operations. As shown in FIG. 4, during the cooling operation, the user can issue instructions to the control source 51 (ie, microcomputer) to perform the cooling operation. At this time, the control source 51 controls the source selection valve 25 to switch to let The liquid of the cooling device 91 flows to the liquid outlet channel 31, and the electronic control valve 15 of the reflux liquid is controlled to switch to allow the liquid of the reflux liquid to enter the channel 11 to flow to the cooling device 91. In addition, the return liquid electronic control valve 15 does not allow liquid to flow into the hot liquid circulation channel 21, and the source selection valve 25 does not allow the liquid in the hot liquid circulation channel 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 the liquid inlet channel 251, and then enter the main shaft 81 of the machine tool through the source selection valve 25 and the liquid outlet channel 31 for cooling; and the liquid is in the tool. After the heat is absorbed in the main shaft 81 of the machine tool, it flows out of the main shaft 81 of the machine tool and enters the return fluid inlet channel 11, and then flows back to the cooling device 91 through the return fluid electronic control valve 15 and the return fluid release channel 151 in. It can be seen from this that when cooling is performed, the present invention only allows the liquid provided by the original cooling device 91 to pass through 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 heating operation, the user can issue an instruction to the control source 51 to perform the heating operation. At this time, the control source 51 controls the reflux electric control valve 15 to switch to allow the reflux The liquid entering the channel 11 flows to the hot liquid circulation channel 21, and the control source 51 also controls the source selection valve 25 to switch so that the liquid in the hot liquid circulation channel 21 flows to the liquid outlet channel 31. At the same time, the return liquid electronic 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 either. Under this heating operation, the control source 51 controls the pump 35 to start. In this way, the liquid flowing out from the liquid outlet 92 of the cooling device 91 will be blocked by the source selection valve 25 after entering the liquid inlet channel 251, and will not enter the source selection valve 25 Moreover, the liquid that the reflux liquid enters the channel 11 cannot flow to the cooling device 91 because of the switching of the reflux liquid electronic control valve 15. The operation of the pump 35 will drive the liquid in the hydrothermal circulation channel 21 to move to the source selection valve 25 and flow to the liquid outlet channel 31. The control source 51 uses the temperature sensor 39 to measure To control the heater 38 to heat the liquid in the liquid outlet channel 31, the heated liquid then flows into the machine tool spindle 81 to provide a heating effect, and the liquid flowing out of the machine tool spindle 81 is The reflux liquid enters the channel 11, and then flows back into the hot liquid circulation channel 21 through the reflux liquid electronic control valve 15. That is, the heated liquid does not flow back into the cooling device 91, but circulates between the main shaft 81 of the machine tool, the return liquid inlet channel 11, the hot liquid circulation channel 21, and the liquid outlet channel 31, and At the same time, it is heated by the heater 38. 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 to achieve rapid heating of the machine tool spindle 81 Effect.

It can be seen from the above that the present invention can provide an additional heating function for the spindle of a machine tool that originally has a cooling device 91, while still retaining its original cooling function, and is an auxiliary device that can provide a temperature adjustment effect for the spindle of the machine tool 10. When the temperature is lowered, the cooling liquid provided by the cooling device 91 is passed through to directly cool the machine tool spindle 81; and when the temperature is raised, the flow path is switched so that the cooling liquid of the cooling device 91 is blocked in this Outside of Invention 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 heats the liquid in this independent circulation channel to achieve a rapid heating effect.

As shown in Figure 3, it should be noted that, in a general machine tool, the components on the machine tool that need to be cooled are usually multiple devices such as the machine tool spindle 81, the motor, and the hollow screw. The pipeline is divided to provide cooling liquid and for its circulation. 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, and it blocks the cooling device 91 during the heating operation. Cooling liquid, this blocking does not cause the cooling device 91 to be unable to output the cooling liquid at all, and the cooling liquid outputted by the cooling liquid will still flow to other devices for cooling through the pipeline. It can be understood here that although in the first embodiment, the components of the machine tool are described with the machine tool spindle 81 as an example, the components of the machine tool that need to be adjusted in temperature can also be changed to motors or hollows. The screw is not limited to the main shaft 81 of the machine tool.

As shown in Fig. 6, under special circumstances, if the cooling liquid output by the cooling device 91 is only used for heat dissipation of the machine tool spindle 81, when the present invention is installed, the control is 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.

Based on the foregoing, it can be seen that the first embodiment can provide a rapid temperature increase effect when the temperature of the machine tool spindle 81 is to be increased. In addition, the first embodiment only needs to install the pipeline between the main shaft 81 of the machine tool and the cooling device 91, and there is no need to modify the original cooling device used with the machine tool.

It should be noted that, referring to Figures 7 and 8, the heater 38 can be located in the liquid outlet channel 31, as shown in Figure 7, in addition to the location of the heater 38. The circulation channel 21, or as shown in FIG. 8, can also be arranged in the return liquid inlet channel 11. However, the preferred position is that the heater 38 is arranged behind the temperature sensor 39 in terms of the liquid flow direction. That is, the liquid first flows through the temperature sensor 39 to sense the temperature, and then flows through the heater 38 for heating. This arrangement 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 before being heated by the heater 38, thereby preventing Because the heater 38 heats the liquid in advance, the measurement of the temperature of the liquid flowing out of the main shaft 81 of the machine tool is not accurate. In addition, two or more heaters 38 may be provided, and they may be installed in accordance with the above-mentioned positions.

In addition, the pump 35 is not only arranged in the hot liquid circulation channel 21 but also in the return 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 arranged in the hot liquid circulation channel 21, the return liquid inlet channel 11 or the liquid outlet channel 31. The reflux liquid circulates among the inlet channel 11, the hot liquid circulation channel 21 and the liquid outlet channel 31. This setting method can be directly understood, and the content is no longer represented in a diagram.

As shown in Fig. 9, the second preferred embodiment of the present invention provides 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, with the difference:

In the second embodiment, the liquid inlet channel and the reflux liquid discharge channel are not provided, but the source selection valve 25' and the reflux liquid electronic control valve 15' are directly connected to the cooling device 91 through a tube 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 fluid electric control valve 15', the source selection valve 25', and the pump 35 through wires. '. That is, the control source 51' of the present invention can be the control box of the machine tool itself or other externally usable 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 use the flow sensor 41' to detect whether the liquid in the hydrothermal circulation channel 21' is flowing, so as to confirm that the pump 35' is operating normally during the heating operation. of.

In addition, the heater and the temperature sensor are not provided in the second embodiment. In the heating operation, the heat generated by the operation of the machine tool spindle 81 itself is mainly used for heating, and the control source 51' is used to control the flow direction of the liquid so that the liquid flowing out of the machine tool spindle 81 is only It can flow back to the main shaft 81 of the machine tool through the return liquid entering channel 11', the hot liquid circulation channel 21', and the liquid outlet channel 31', and by this circulation, the main shaft 81 of the machine tool can be used during operation. The generated heat provides a heating 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 the corresponding operation or reaction.

It should also be noted that, in the second embodiment, the components of the machine tool are still described with 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 main shaft 81 of the machine tool.

In the second embodiment, the use of an external control source 51' can increase the openness of the control of the present invention, and give manufacturers more choices.

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.
