Description
Technical Field
[0001] This utility model belongs to the field of CNC machine tool equipment technology, and specifically relates to an automatic fluid replenishment device for CNC machine tools. Background Technology
[0002] CNC machine tools are short for numerical control machine tools. They are automated machine tools equipped with a program control system. This control system can logically process programs with control codes or other symbolic instructions, decode them, represent them with coded numbers, input them to the numerical control device through an information carrier, and after calculation and processing, the numerical control device sends out various control signals to control the machine tool's movements. It automatically processes parts according to the shape and size required by the drawings. Currently, CNC machine tools use cutting fluid to assist in machining.
[0003] Chinese patent CN202410503139.1 discloses a CNC machine tool for metal products, including a CNC machine tool, a base plate, a monitoring camera, a servo tool post, a fixed plate, a tool holder, a cutting tool, and an electric clamp. The base plate is fixedly connected to the CNC machine tool. A monitoring camera is installed on the CNC machine tool. A servo tool post is installed on the CNC machine tool. A fixed plate is fixedly connected to the CNC machine tool. A tool holder is connected to the servo tool post. A cutting tool is installed on the tool holder. An electric clamp is provided on the upper part of the base plate. It also includes a drive mechanism, a support frame, a ring, a sliding ring, and elastic elements. The drive mechanism is connected to the lower surface of the fixed plate. The drive mechanism is connected to the support frame. The drive mechanism is used to drive the support frame to move. A ring is fixedly connected to the lower surface of the support frame. A groove is opened in the middle of the ring, and a sliding ring is slidably connected in the groove. At least four elastic elements are fixedly connected to the upper surface of the sliding ring at equal intervals, and the other end of all the elastic elements is fixedly connected to the ring.
[0004] Currently, CNC machine tools generally require the use of cutting fluid for auxiliary machining during operation. However, when replenishing cutting fluid, the container is usually flat-bottomed, which makes it impossible to collect the cutting fluid in the container in a timely manner. As a result, when the cutting fluid is found to be insufficient and needs to be replenished, the cutting fluid at the bottom will not be used, leading to waste and hindering the timely use of cutting fluid.
[0005] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0007] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0008] This utility model relates to an automatic fluid replenishment device for CNC machine tools, comprising a mounting base, the top of which is connected to a machine table body, a control cabinet connected to one side of the machine table body, a housing connected to the top of the mounting base, a top plate connected to the top of the housing, and a drive assembly mounted on the housing.
[0009] A liquid replenishment pipe is connected to one side of the control cabinet, a control valve is connected to the surface of the liquid replenishment pipe, a solenoid valve is connected to the surface of the liquid replenishment pipe, an inlet pipe is connected to the top of the solenoid valve, an induction alarm is connected to the front of the control cabinet, a drive source is connected to the top of the mounting base, and a fixing plate is connected to the back of the cabinet.
[0010] The surface of the drive assembly is poweredly connected to the power output end of the drive source to drive the drive assembly to move back and forth for position adjustment and to guide the cutting fluid.
[0011] Furthermore, the drive assembly includes a main bevel gear, a connecting rod, a connecting screw, a guide plate, and a connecting plate. The main bevel gear is disposed on the power output end of the drive source. The connecting rod is rotatably disposed on the surface of the fixed plate. One end of the connecting rod is connected to a secondary bevel gear, which meshes with the main bevel gear. The connecting screw is disposed on the surface of the secondary bevel gear.

A second alarm triggers the solenoid valve to open, replenishing the cutting fluid to the housing via the replenishment pipe. This automatic replenishment prevents unusable fluid from remaining at the bottom of the housing, thus avoiding waste. The operation is simple.

[0029] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the utility model, and not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.
[0030] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "top", "middle", "inner", etc., which indicate orientation or positional relationship, are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the utility model.
[0031] Please see Figures 1-6 As shown, this utility model is an automatic fluid replenishment device for CNC machine tools, including a mounting base 1. The top of the mounting base 1 is connected to a machine table body 3. A control cabinet 4 is connected to one side of the machine table body 3. A housing 5 is connected to the top of the mounting base 1. A top plate 6 is connected to the top of the housing 5. A drive assembly 2 is provided on the housing 5.
[0032] One side of the control cabinet 4 is connected to a liquid replenishment pipe 7, the surface of the liquid replenishment pipe 7 is connected to a control valve 8, the surface of the liquid replenishment pipe 7 is connected to a solenoid valve 9, the top of the solenoid valve 9 is connected to an inlet pipe 10, the front of the control cabinet 4 is connected to a sensor alarm 11, the top of the mounting base 1 is connected to a drive source 12, and the back of the housing 5 is connected to a fixing plate 13.
[0033] The surface of the drive component 2 is poweredly connected to the power output end of the drive source 12 to drive the drive component 2 to move back and forth for position adjustment and to guide the cutting fluid.
[0034] First, when the cutting fluid inside the housing 5 is about to run out, the sensor alarm 11 sounds the first alarm. At this time, the drive source 12 receives the alarm signal and controls the drive component 2 to operate. The drive source 12 pushes the cutting fluid toward the sensor alarm 11. Because the bottom of the housing 5 has a large space and the bottom of the housing 5 is flat, pushing the cutting fluid toward the sensor alarm 11 at this time concentrates the cutting fluid around the sensor alarm 11, minimizing the waste of cutting fluid. After the sensor alarm 11 sounds the alarm for the second time, it sends a signal of insufficient cutting fluid to the control valve 8. The control valve 8 allows the cutting fluid to enter the housing 5 through the replenishment pipe 7 for replenishment. The automatic replenishment of cutting fluid also avoids the situation where there is always cutting fluid at the bottom of the housing 5 that cannot be used and thus wastes it. The operation is simple.
[0035] The drive component 2 facilitates pushing the cutting fluid at the bottom of the housing 5 towards the sensor 11 when the sensor 11 issues its first low-fluid alarm. This prevents the cutting fluid from being unable to concentrate due to the flat bottom of the housing 5, thus minimizing the waste of cutting fluid. When the sensor 11 issues its second alarm, it controls the solenoid valve 9 to open and replenish the cutting fluid to the inside of the housing 5 via the replenishment pipe 7. This automatic replenishment of cutting fluid also prevents the bottom of the housing 5 from always having unusable cutting fluid, thus avoiding waste. The operation is simple.
[0036] In one embodiment, the drive assembly 2 includes a main bevel gear 21, a connecting rod 22, a connecting screw 24, a guide plate 27, and a connecting plate 28. The main bevel gear 21 is disposed on the power output end of the drive source 12. The connecting rod 22 is rotatably disposed on the surface of the fixed plate 13. One end of the connecting rod 22 is connected to a secondary bevel gear 23, which meshes with the main bevel gear 21. The connecting screw 24 is disposed on the surface of the secondary bevel gear 23. A baffle 25 is threadedly connected to the surface of the connecting screw 24 via a screw nut. A plurality of compound push springs 26 are connected to the top of the baffle 25. The guide plate 27 is disposed on the inner side of the bottom end of the housing 5. The connecting plate 28 is disposed on the bottom end of the top plate 6. A slider 29 is connected to the top of the plurality of compound push springs 26.
[0037] First, when the cutting fluid inside the housing 5 is about to run out, the sensor alarm 11 sounds an alarm. At this time, the drive source 12 receives the alarm signal and controls the main bevel gear 21 to rotate. The main bevel gear 21 drives the meshing secondary bevel gear 23 to rotate, which in turn drives the connecting screw 24 to rotate. This causes the baffle 25, which is threadedly connected to the connecting screw 24, to move towards the sensor alarm 11. Then, through the downward pushing action of the compound push spring 26, the baffle 25 will always move towards the sensor alarm 11 while pressing downward, that is, the bottom end of the baffle 25 will always be in contact with the top surface of the guide plate 27, avoiding... To prevent gaps from affecting the flow of cutting fluid, and by using a slider 29 that slides along a groove inside the top plate 6, the smoothness of the baffle 25's movement is improved. At this time, the cutting fluid remaining at the bottom of the tank 5 flows towards the sensor alarm 11, thus achieving the first step of replenishment. After the second alarm 11 sounds, it sends a signal indicating a lack of cutting fluid to the control valve 8. The control valve 8 then allows the cutting fluid to enter the tank 5 through the replenishment pipe 7 for replenishment. This automatic replenishment of cutting fluid also avoids the situation where cutting fluid remains unusable at the bottom of the tank 5, resulting in waste. The operation is simple.
[0038] The main bevel gear 21 facilitates the linkage rotation of the secondary bevel gear 23 and the connecting screw 24, which in turn facilitates the movement and adjustment of the baffle 25. This allows the cutting fluid at the bottom of the housing 5 to be pushed towards the alarm 11 when the alarm 11 sounds for the first time, preventing the cutting fluid from being unable to concentrate due to the flat bottom of the housing 5 and minimizing waste. The second alarm from the alarm 11 controls the opening of the solenoid valve 9 to replenish the cutting fluid to the inside of the housing 5 via the replenishment pipe 7. This automatic replenishment of cutting fluid also prevents the waste caused by the constant presence of unusable cutting fluid at the bottom of the housing 5. The operation is simple.
[0039] In one embodiment, for the aforementioned connecting screw 24, one end of the connecting screw 24 is rotatably connected to one side of the connecting plate 28 via a bearing, thereby improving the stability of the rotation of the connecting screw 24.
[0040] In one embodiment, the connecting screw 24 is provided with a wear-resistant sealing ring on its surface. The surface of the wear-resistant sealing ring is rotatably connected to the interior of the back of the housing 5, thereby improving the wear resistance of the connecting screw 24 while preventing the leakage of cutting fluid.
[0041] In one embodiment, the bottom end of the baffle 25 is in contact with the top end of the guide plate 27 to avoid gaps that would prevent the cutting fluid from being concentrated.
[0042] In one embodiment, for the top plate 6, a groove is provided on the inner side of the bottom end of the top plate 6, and the surface of the slider 29 is slidably connected to the inner side of the groove, thereby improving the smoothness of the movement of the baffle 25 without affecting the fit between the baffle 25 and the guide plate 27.
[0043] In one embodiment, for the aforementioned inlet pipe 10, one end of the inlet pipe 10 is connected to the front of the control cabinet 4, and the sensor alarm 11 is located inside the housing 5, thereby facilitating timely feedback on the remaining amount of cutting fluid inside the housing 5.
[0044] In summary, with the help of the above-mentioned technical solution of this utility model, when the cutting fluid inside the housing 5 is about to be exhausted, the sensor alarm 11 issues the first alarm. At this time, the drive source 12 receives the alarm signal and controls the main bevel gear 21 to rotate. The main bevel gear 21 drives the secondary bevel gear 23, which meshes with it, to rotate, and then drives the connecting screw 24 to rotate in conjunction. At this time, the baffle 25, which is threadedly connected to the connecting screw 24, moves toward the sensor alarm 11. Then, through the downward pushing action of the compound push spring 26, the baffle 25 will always move toward the sensor alarm 11 while pressing downward, that is, the bottom end of the baffle 25 is always in contact with the guide plate 2. The top surface of the baffle 25 is fitted together to avoid gaps that could affect the flow of the cutting fluid. The slider 29, which slides along the groove inside the top plate 6, improves the smoothness of the movement of the baffle 25. At this time, the cutting fluid remaining at the bottom of the tank 5 flows towards the sensor alarm 11, thus achieving the first step of replenishment. After the second alarm 11 sounds, it sends a signal of insufficient cutting fluid to the control valve 8. The control valve 8 allows the cutting fluid to enter the tank 5 through the replenishment pipe 7 for replenishment. This automatic replenishment of cutting fluid also avoids the situation where there is always cutting fluid at the bottom of the tank 5 that cannot be used, thus avoiding waste. The operation is simple.
[0045] Through the above technical solution, the main bevel gear 21 facilitates the linkage rotation of the secondary bevel gear 23 and the connecting screw 24, which in turn facilitates the movement and adjustment of the baffle 25. When the induction alarm 11 issues its first low-temperature alarm, the cutting fluid at the bottom of the housing 5 is pushed towards the induction alarm 11, thus avoiding the situation where the cutting fluid cannot be concentrated because the bottom of the housing 5 is flat. This minimizes the waste of cutting fluid. When the induction alarm 11 issues its second alarm, it controls the solenoid valve 9 to open and replenish the cutting fluid to the inside of the housing 5 through the replenishment pipe 7. The automatic replenishment of cutting fluid also avoids the situation where there is always cutting fluid at the bottom of the housing 5 that cannot be used, thus preventing waste. The operation is simple.
