Description

TECHNICAL FIELD

[0001] The utility model relates to machine tool cutting fluid technical field, concretely relates to an intelligent liquid supplementing device. BACKGROUND

[0002] In the machine tool processing, cutting operation can produce a large amount of heat energy, so that the tool and workpiece temperature rises sharply, directly threatens the machining accuracy and tool durability. In order to effectively deal with this problem, cutting fluid cooling and lubrication are used.

[0003] At present, the filling process of cutting fluid is roughly as follows: cutting fluid is first added to the cutting fluid preparation tank, then the liquid level sensor arranged in the preparation tank is responsible for monitoring the liquid level change and transmitting the monitoring data to the display device. In this process, the operator needs to pay attention to the liquid level information on the display device at all times, and manually adjusts the supplement of cutting fluid according to the actual situation. Although this method can realize the supplement of cutting fluid to a certain extent, it exposes many problems in actual operation.

[0004] The first problem is that the liquid supplementing efficiency is low. The manual monitoring method not only consumes time and effort, but also is difficult to realize accurate control, resulting in frequent fluctuation of liquid level and greatly reducing the stability of machine tool operation. Secondly, the liquid level monitoring system often lacks accuracy and cannot accurately reflect the real liquid level of cutting fluid in the preparation tank in real time. The liquid supplementing operation is often delayed, either over-supplementing or under-supplementing, which is not conducive to the normal operation of machine tool. Thirdly, the liquid supplementing flow control lacks accuracy, and the flow fluctuation range is large, which not only wastes resources, but also may damage the structure of the preparation tank. Finally, the liquid supplementing process highly depends on manual operation, and the automation degree is low, which not only greatly increases the labor intensity of the operator, but also increases the risk of liquid supplementing failure and even safety accidents due to human factors.

DETAILED DESCRIPTION

[0024] The specific embodiments of the present application will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the present application, but cannot be used to limit the scope of the present application.

[0025] Example 1:

[0026] As shown in the drawings, the intelligent liquid supplementing device of the present embodiment is used for supplementing liquid in a machining cutting fluid preparation tank, and comprises a connecting tank 1 for temporarily storing supplementing liquid, a control device 2, a machine tool connecting pipe 3 and a lifting base 4. The connecting tank 1 is provided with a water level adjusting unit 5 and an auxiliary water level detection module 6. The water level adjusting unit 5 is used for detecting and supplementing the supplementing liquid in the connecting tank 1, and the auxiliary water level detection module 6 is used for further confirming the liquid level state. Figures 1-5 Further, the water level adjusting unit 5 comprises a liquid supply pipe 51, a communication pipe 53 and an adjusting assembly 54a. The communication pipe 53 is vertically arranged at the top end of the connecting tank 1 and communicates with the inside of the connecting tank 1. The liquid supply pipe 51 is connected to the top end of the communication pipe 53 and is used for injecting supplementing liquid into the communication pipe 53. A manual ball valve 52 is arranged outside the liquid supply pipe 51 to adjust the liquid inflow rate. This makes the supplementing process more flexible and controllable, and the addition of the manual ball valve 52 provides additional safety protection and adjustment means.

[0027] Further, the adjusting assembly 54a comprises a pneumatic ball valve 54 and a solenoid valve 55. The pneumatic ball valve 54 is divided into a normally open valve 541 and a normally closed valve 542. Both the normally open valve 541 and the normally closed valve 542 are correctly arranged outside the communication pipe 53 to control the communication state between the communication pipe 53 and the inside of the connecting tank 1. The normally open valve 541 is above the normally closed valve 542, and both the normally open valve 541 and the normally closed valve 542 are equipped with solenoid valves 55 outside to realize automatic control. This realizes automatic control of the supplementing process, improves the supplementing efficiency and accuracy, and reduces the need for manual intervention.

[0028] Further, the water level adjusting unit 5 further comprises a pressure regulating table 56, which is arranged beside the connecting tank 1 and is associated with the pneumatic ball valve 54 to adjust the working pressure of the pneumatic ball valve 54. The addition of the pressure regulating table 56 enables the supplementing flow to be more accurately controlled, further improving the stability and accuracy of the supplementing process.

[0029]

[0030] ​Furthermore, the auxiliary water level detection module 6 includes an electrode-type liquid level switch 61, a mounting bracket 62, a slide bar 63, a float 64, and high / low liquid level sensors 65. The mounting bracket 62 is located at the top of the connecting box 1. The slide bar 63 is movably mounted in the mounting bracket 62 and can move vertically. The float 64 is connected to the side of the slide bar 63 near the connecting box 1 and is placed inside the connecting box 1, moving with the rise and fall of the liquid level. The high / low liquid level sensor 65 is located on the side of the slide bar 63 away from the connecting box 1, used to detect the movement position of the slide bar 63 in real time, i.e., the liquid level state inside the connecting box 1, and transmits the detection signal to the control device 2. This design realizes real-time monitoring and accurate feedback of the liquid level inside the connecting box 1, providing reliable liquid level information for the control device 2.

[0031] Example 2:

[0032] Compared to Example 1, such as Figures 1-5 The control device 2 receives signals from the water level regulating unit 5 and the auxiliary water level detection module 6, and controls the fluid replenishment process, including opening or closing the manual ball valve 52, the normally open valve 541, and the solenoid valve 55 of the normally closed valve 542 of the supply pipe 51, and adjusting the set value of the pressure gauge 56, thereby ensuring that the fluid level in the cutting fluid mixing tank is maintained within the preset range. This achieves comprehensive monitoring and precise control of the fluid replenishment process, ensuring that the fluid level in the cutting fluid mixing tank is stably maintained within the preset range.

[0033] In actual operation, the liquid level inside the connection box 1 is monitored in real time by the electrode-type liquid level switch 61, mounting bracket 62, slide rod 63, float 64, and high / low liquid level sensor 65 in the auxiliary water level detection module 6. The float 64 moves with the rise and fall of the liquid level, causing the slide rod 63 to move vertically in the mounting bracket 62. The high / low liquid level sensor 65 detects the position of the slide rod 63, i.e., the liquid level height, in real time and transmits the signal to the control device 2.

[0034] Meanwhile, the supply pipe 51, connecting pipe 53, and regulating component 54a in the water level regulating unit 5, including the normally open valve 541 and normally closed valve 542 of the pneumatic ball valve 54, the solenoid valve 55, and the pressure gauge 56, work together to detect and replenish the replenishing liquid inside the connection box 1. When the liquid level in the connection box 1 is lower than the preset supply liquid level, the control device 2 receives a signal from the auxiliary water level detection module 6, triggering the automatic replenishment program. At this time, the solenoid valve 55 controls the normally open valve 541 to open and the normally closed valve 542 to open, allowing the replenishing liquid to enter the connection box 1 through the supply pipe 51 and connecting pipe 53. At the same time, the pressure gauge 56 adjusts the working pressure of the pneumatic ball valve 54, thereby controlling the replenishment flow rate.

[0035] During the liquid supplement process, the control device 2 continuously receives the liquid level signals from the auxiliary water level detection module 6 and adjusts the liquid supplement rate in real time according to the liquid level change. When the liquid level in the connection box 1 reaches the preset high liquid level setting value, the liquid supplement program stops, the electromagnetic valve 55 controls the normally open valve 541 to be closed and the normally closed valve 542 to be closed to prevent excessive liquid supplement.

[0036] In addition, the manual ball valve 52 serves as a backup control means and allows the operator to manually adjust the liquid supplement rate or stop the liquid supplement when necessary.

[0037] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the technical principles of the present application, a number of improvements and refinements can be made, and these improvements and refinements should be considered as the protection scope of the present application.
