Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of flow lubrication, and particularly relates to a flow monitoring device with multiple branch channels. Background Art
[0002] In precision machining, the workbench of a machine tool needs to slide along the guide rail. To ensure the smoothness and stability of the sliding, lubricating oil needs to be injected between the guide rail and the workbench.
[0003] If there is too much lubricating oil, the sliding resistance between the workbench and the guide rail is small. If there is too little lubricating oil, the sliding resistance will increase. In the case of extremely high machining accuracy requirements, too small or too large sliding resistance will affect the machining accuracy. Because during the machining process, sometimes the workbench needs to move and machine simultaneously, so the control of the lubricating oil output is very crucial.
[0004] In the prior art, to ensure that the lubricating oil supply is within a reasonable range, it is often necessary to manually measure the lubricating oil flow rate of each branch channel leading to the guide rail and the workbench at regular intervals. For example, the end of the branch channel is disassembled, and the lubricating oil flowing out of the branch channel within a specified time is collected in an oil cup. This method has little impact on the working efficiency of the machine tool when there are few branch channels. However, if there are many branch channels, it is necessary to measure each branch channel separately and reconnect them, which is not only cumbersome in operation but also not conducive to the real-time monitoring of lubricating oil.
[0005] In the prior art, for such situations, it is often necessary to install flow meters on each branch channel to monitor each branch. However, this method of installing flow meters on each branch channel greatly increases the monitoring cost. Summary of the Utility Model
[0006] The utility model aims to provide a flow monitoring device with multiple branch channels to solve the problems of cumbersome monitoring operations or high monitoring costs existing in the flow monitoring of multiple branches in the prior art.
[0007] To achieve the above object, the utility model adopts the following technical scheme:
[0008] A flow monitoring device with multiple branch channels includes multiple branch channels, and also includes a monitoring main channel and multiple monitoring sub-channels connected to the output end of the monitoring main channel. The input end of the monitoring main channel is connected to the input ends of all branch channels. The number of monitoring sub-channels is not less than the number of branch channels, and one end of the output of each branch channel is connected to the output end of a corresponding monitoring sub-channel. Valves are installed on each branch channel and each monitoring sub-channel, and a flow meter is installed on the monitoring main channel.
[0009] Preferably, as an improvement, a regulating valve is installed on a section of the output end of the branch channel, so that when the flow rate measured by the flow meter exceeds the design range, timely adjustment can be made through the regulating valve.
[0010] Preferably, as an improvement, a main channel communicating with the input ends of all branch channels is further included, and the input end of the main channel is communicated with the input end of the monitoring main channel to facilitate reducing the cumulative length of the pipeline.
[0011] Preferably, as an improvement, the monitoring main channel and the main channel are both communicated with an equipped fuel tank.
[0012] Preferably, as an improvement, the valve on the branch channel is a normally open valve.
[0013] Preferably, as an improvement, the valve on the monitoring branch channel is a normally closed valve.
[0014] Preferably, as an improvement, a controller is further included. The controller is connected to all valves. The controller is used to control the interlocking of the valves communicating with the same branch channel. The interlocking of the valves communicating with the same branch channel means that when one of the valve on the branch channel and the corresponding valve on the monitoring branch channel is opened, the other is closed. When the valve on the monitoring branch channel is opened and the valve on the branch channel is closed, it means that the output flow rate of this branch channel is measured.
[0015] Preferably, as an improvement, the controller is used to sequentially switch the interlocking situation of the valves on the branch channels, and control them in turn to ensure the timing of monitoring, and at the same time ensure that the output flow rate of each branch channel is measured each time.
[0016] The principle and advantages of this solution are as follows: When this solution is adopted, the valve on the branch channel is in the normally open state, while the valve on the monitoring branch channel is in the normally closed state. When the flow rate does not need to be measured, the lubricating oil directly passes through each branch channel to the destination. When it is necessary to detect the flow rate of the output end of each branch channel, because a section of the output end of each branch channel is connected to the output end of a corresponding monitoring branch channel, and valves are installed on each branch channel and each monitoring branch channel. When it is necessary to measure the output flow rate of one of the branch channels, only need to close the valve on the corresponding branch channel and switch the valve on the corresponding monitoring branch channel from the normally closed state to the open state, then the same number of lubricating oil outlets are still ensured. At this time, the monitoring main channel is only communicated with the monitoring branch channel through which the lubricating oil passes, so the flow meter on the monitoring main channel monitors the flow rate of the corresponding lubricating oil outlet; and if it is necessary to detect the output flow rate of other branch channels, use the same method, close the valve on the branch channel to be monitored and open the valve on the corresponding connected monitoring branch channel, then the flow rate monitoring of the output of the corresponding branch channel can be realized.
[0017] Compared with the prior art, it is only necessary to control the opening and closing of the valves to monitor the output flow of each branch channel. The operation is simple and convenient, and there is no problem of cumbersome operation in the prior art. At the same time, for the flow monitoring of multiple branch channels, only the number of valves and pipelines need to be increased, and only one flowmeter is required. Based on the fact that the cost of the flowmeter is much higher than that of the pipeline and the valve, the cost is greatly reduced compared with the scheme of installing a flowmeter for each branch channel.

[0023] The following is a more detailed description through specific embodiments:
[0024] The reference numerals in the accompanying drawings of the specification include: flowmeter 1, fuel tank 2, and machine tool guide rail 3.
[0025] The embodiment is basically as shown in the Figures 1 to 5 accompanying drawings.
[0026] A flow monitoring device for multiple branch channels includes a main channel, multiple branch channels, a monitoring main channel, and multiple monitoring shunt channels. The input ends of the main channel and the monitoring main channel are both connected to the fuel tank. The number of branch channels is the same as the number of monitoring shunt channels. The input end of the branch channel is connected to the output end of the main channel. The output end of the branch channel corresponds to the lubrication port of a guide rail for supplying oil to the guide rail of the machine tool. A normally open valve is installed at one end of each branch channel close to the main channel, and a flow regulating valve is installed on a section of each branch channel close to the output port.
[0027] A flowmeter is installed on the main monitoring flow channel. All the monitoring branch flow channels are connected to the output end of the main monitoring flow channel. A normally closed valve is installed on each monitoring branch flow channel. One end of the output of each branch flow channel is connected to the output end of a corresponding monitoring branch flow channel. The flow regulating valve is located between the output end of the monitoring branch flow channel and the outlet of the branch flow channel.
[0028] In this embodiment, both the normally open valve and the normally closed valve adopt two-way two-port valves.
[0029] Taking four branch flow channels and four monitoring branch flow channels as an example in this embodiment, the valves on the four branch flow channels are respectively A1, B1, C1, D1, the valves on the four monitoring branch flow channels are respectively A2, B2, C2, D2, and the outlets of the four branch flow channels are respectively A3, B3, C3, D3. A1 - A2 - A3 is a corresponding associated structure, B1 - B2 - B3 is a corresponding associated structure, and C1 - C2 - C3 is a corresponding associated structure.
[0030] When this embodiment is adopted, the valves on the branch flow channels are in the normally open state, while the valves on the monitoring branch flow channels are in the normally closed state. When the flow rate does not need to be measured, the entire monitoring device is in Figure 1 the state shown.
[0031] When it is necessary to monitor the flow rate of the A3 outlet shown in the figure, the entire monitoring device is in Figure 2 the state. In this state, only the A1 valve of the branch flow channel is closed while the A2 valve of the monitoring branch flow channel is opened, and the flowmeter monitors the flow rate of the A3 outlet.
[0032] Similarly, when monitoring the flow rate of the B3 outlet shown in the figure, the entire monitoring device is in Figure 3 the state. In this state, only the B1 valve of the branch flow channel is closed while the B2 valve of the monitoring branch flow channel is opened, and the flowmeter monitors the flow rate of the B3 outlet.
[0033] Similarly, the principle of monitoring the flow rates of the C3 and D3 outlets is the same. The attached drawings are respectively shown in Figure 4 and Figure 5 the figure shown.
[0034] Through adding a main monitoring flow channel, monitoring branch flow channels, a flowmeter and multiple normally closed valves to the original lubricating oil path in the whole embodiment, the flow rate monitoring of each branch flow channel can be realized without disassembling the connection relationship of the outlet, and the monitoring method is simple and convenient.
[0035] In addition, for the flow rate monitoring of multiple branch flow channels, only the number of valves and pipelines needs to be increased, and then a flowmeter is equipped. Based on the fact that the cost of the flowmeter is much higher than that of the pipeline and the valve, the cost is also greatly reduced compared with the scheme of installing a flowmeter on each branch flow channel.
[0036] Embodiment 2
[0037] Based on Embodiment 1, Embodiment 2 further includes a controller. The controller is connected to all valves. The controller is used to control the valves connected to the same branch channel to be interlocked. The interlock of the valves connected to the same branch channel means that when one of the valves on the branch channel and the corresponding valve on the monitored shunt channel is opened, the other is closed. When the valve on the monitored shunt channel is opened and the valve on the branch channel is closed, it means that the output flow of this branch channel is measured.
[0038] The controller is used to sequentially switch the interlock situation of the valves on the branch channels and control them in turn to ensure the timing of monitoring, and at the same time ensure that the output flow of one branch channel is measured each time.
[0039] The controller is used to issue an alarm when the monitored flow is not within the set range.
[0040] This embodiment has a higher degree of automation compared to Embodiment 1.
[0041] The above are only embodiments of the present invention. Specific technical solutions and / or common knowledge such as characteristics well known in the art are not described in detail here. It should be noted that for those skilled in the art, without departing from the technical solution of the present invention, several deformations and improvements can still be made, and these should also be regarded as the protection scope of the present invention, and these will not affect the implementation effect of the present invention and the practicality of the patent. The protection scope required by this application should be based on the content of its claims, and the specific implementation manners described in the specification can be used to interpret the content of the claims.
