Description

Technical Field

[0001] This utility model relates to the field of machine tool gearbox maintenance technology, specifically to a manual lubrication oil filling and leak-proof connector for machine tool gearboxes. Background Technology

[0002] In the process of machine manufacturing, machine tools are used to process mechanical parts. During the processing of machine tools, gearboxes are used to drive the machine tools. During the operation of the machine tool gearbox, the gears will rub against each other, and lubricating oil needs to be dripped between the gears regularly. Currently, the gearbox spindle is mostly manually lubricated by dripping lubricating oil between the gears using tools.

[0003] A search revealed application number CN202420766845.0, entitled "A Machine Tool Gearbox Spindle Structure." This application proposes a machine tool gearbox spindle structure that stores lubricating oil in an oil box and adds it to the gears via a filling pipe to enhance lubrication. However, after a period of use, the lubricating oil in the oil box decreases, requiring refilling. Due to the small filling port, manual refilling requires the use of a funnel. Traditional funnels lack a connector structure, making them unstable and prone to wobbling when inserted into the filling port, sometimes even tilting and falling, leading to oil leakage. The funnel requires one hand to hold, which is inconvenient and affects usability. Further improvements are needed. Additionally, it is difficult for operators to judge the correct amount of oil, easily leading to overfilling or underfilling. Overfilling can cause lubricating oil overflow and leakage, affecting stability and usability. Further improvements are also needed in this regard.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a manual lubrication oil filling and leak-proof connector for machine tool gearboxes, which has the advantages of stable and convenient use, thereby solving the problems mentioned in the background technology.

[0006] To achieve the aforementioned advantages of stable and convenient use, the specific technical solution adopted by this utility model is as follows:

[0007] A manual lubricating oil filling and leak-proof connector for machine tool gearboxes includes a connector tube and a scale. The top opening of the connector tube is connected to an oil filling hopper, and a connector cover is fixedly sleeved on the outer wall of the top of the connector tube. A handle bolt is threaded through the surface of the connector cover. One end of the handle bolt is rotatably connected to a clamping ring via a rotating connecting seat. A scale is connected through the inside of the connector tube, and a float is fixedly connected to the bottom surface of the scale. The scale is printed with graduations.

[0008] Furthermore, a limiting rod is fixedly installed on the top surface of the scale, and the length of the limiting rod is greater than the radius of the top opening of the oil filling hopper.

[0009] Furthermore, the outer diameter of the float is larger than the inner diameter of the bottom opening of the connector pipe, and the outer diameter of the float is smaller than the inner diameter of the oil filling port.

[0010] Furthermore, a guide ring is slidably sleeved on the surface of the scale, and the outer wall of the guide ring is fixedly connected to the inner wall of the connector tube via a connecting rod.

[0011] Furthermore, two sets of guide rings are arranged from top to bottom, and the guide rings are coaxially arranged with the connector pipe and the oil injection hopper.

[0012] Furthermore, the connecting rods are arranged in a cross shape, and the connecting rods are smooth round rods.

[0013] Furthermore, the clamping rings are arranged in two sets, and the surface of the clamping rings is roughened, and the clamping rings adopt an arc-shaped structure.

[0014] Furthermore, the distance between the bottom opening of the connector tube and the bottom opening of the connector cover is not less than 5cm, and the inner diameter of the connector cover is greater than the outer diameter of the oil inlet, while the outer diameter of the connector tube is smaller than the inner diameter of the oil inlet.

[0015] Compared with the prior art, this utility model provides a manual lubrication oil filling and leak-proof connector for machine tool gearboxes, which has the following beneficial effects:

[0016] (1) This utility model adopts a clamping ring, a connector tube and a connector cover. When adding lubricating oil to the gearbox lubricating oil tank, the bottom of the connector tube can be inserted into the lubricating oil tank through the oil filling port. At this time, the connector cover is located outside the oil filling port. The operator can rotate the handle bolt to drive the clamping plate to move and clamp the oil filling port, thereby fixing the connector cover and the connector tube, and then fixing the oil filling hopper. The operator can then manually add lubricating oil into the oil filling hopper to complete the lubricating oil addition. During the manual addition process, the connector tube and the oil filling hopper are fixed and will not fall or tilt, making it more stable, avoiding the accident of lubricating oil leakage, improving the stability of the work, saving the trouble of manual support, and improving the convenience of use.

[0017] (2) This utility model uses a float ball. The float ball is inserted into the lubricating oil tank and floats on the top surface of the lubricating oil. As the lubricating oil is continuously added, the float ball gradually rises with the liquid level. The staff can judge the amount of oil added by observing the scale to avoid overfilling or underfilling. At the same time, when the float ball rises to the point of blocking the bottom of the connector pipe, the lubricating oil cannot enter the lubricating oil tank further, avoiding the trouble of accidental overfilling and the problem of overfilling leakage, and further improving the convenience and stability of use.

[0025] To further illustrate the various embodiments, the present invention provides accompanying drawings, which are part of the disclosure of the present invention. These drawings are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, those skilled in the art should be able to understand other possible implementation methods and the advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are usually used to represent similar components.

[0026] According to an embodiment of the present invention, a machine tool gearbox lubricating oil manual filling leak-proof connector is provided.

[0027] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments, such as... Figure 1-4As shown, a manual lubricating oil filling and leak-proof connector for machine tool gearboxes according to an embodiment of this utility model includes a connector tube 2 and a scale 6. An oil filling hopper 1 is connected through the top opening of the connector tube 2. The oil filling hopper 1 has a large top opening for easy manual lubricating oil filling. A connector cover 3 is fixedly sleeved on the top outer wall of the connector tube 2. The connector cover 3 and the connector tube 2 are coaxially arranged and integrally formed. A handle bolt 4 is threaded through the surface of the connector cover 3. Two sets of handle bolts 4 are symmetrically arranged along the vertical center line of the connector tube 2. One end of the handle bolt 4 is rotatably connected to a clamping ring 11 via a rotating connecting seat 12. The maximum spacing of the clamping rings 11 is greater than the outer diameter of the oil filling port, and the inner diameter of the clamping rings 11 matches the outer diameter of the oil filling port. A scale 6 is connected through the inside of the connector tube 2, and a float 9 is fixedly connected to the bottom surface of the scale 6. The float 9 has a hollow structure. Both 9 and scale 6 are made of plastic, making them lighter and less dense, and easier for the lubricating oil to support. Scale 6 is also printed with graduations 7 for easy observation by staff. When adding lubricating oil to the gearbox lubricating oil tank, the bottom of connector tube 2 can be inserted into the lubricating oil tank through the oil inlet. At this time, connector cover 3 is located outside the oil inlet. Staff can rotate handle bolt 4 to move the clamping plate to clamp the oil inlet, thus fixing connector cover 3 and connector tube 2, and consequently fixing oil hopper 1. Staff can then manually add lubricating oil to oil hopper 1. During manual adding, connector tube 2 and oil hopper 1 are fixed, preventing them from falling or tilting, ensuring greater stability, avoiding lubricating oil leakage accidents, improving work stability, eliminating the hassle of manual support, and increasing ease of use.

[0028] In one embodiment, a limiting rod 8 is fixedly installed on the top surface of the scale 6, and the length of the limiting rod 8 is greater than the radius of the top opening of the oil filling hopper 1. Two sets of limiting rods 8 are arranged to limit the movement, preventing the limiting rod 8 from entering the oil filling hopper 1 and avoiding separation of the scale 6 from the connector pipe 2.

[0029] In one embodiment, the outer diameter of the float 9 is larger than the inner diameter of the bottom opening of the connector pipe 2, allowing it to move upwards and seal the bottom opening of the connector pipe 2. The outer diameter of the float 9 is smaller than the inner diameter of the oil inlet, facilitating its insertion into the oil box through the oil inlet. Once inserted into the lubricating oil tank, the float 9 floats on the top surface of the lubricating oil. As lubricating oil is continuously added, the float 9 gradually rises with the liquid level. Operators can judge the amount added by observing the scale 7, avoiding overfilling or underfilling. Simultaneously, when the float 9 rises to seal the bottom opening of the connector pipe 2, lubricating oil cannot further enter the lubricating oil tank, preventing accidental overfilling and leakage, further improving the convenience and stability of use.

[0030] In one embodiment, a guide ring 5 is slidably sleeved on the surface of the scale 6, and the outer wall of the guide ring 5 is fixedly connected to the inner wall of the connector tube 2 through the connecting rod 10. The guide ring 5 is polished to guide the scale 6, prevent the scale 6 from tilting, and stabilize the up and down movement of the scale 6.

[0031] In one embodiment, two sets of guide rings 5 ​​are arranged from top to bottom, and the guide rings 5 ​​are coaxially arranged with the connector pipe 2 and the oil filling hopper 1. The multiple sets of guide rings 5 ​​improve the stability of guiding the scale 6 and further improve the stability of the operation.

[0032] In one embodiment, the connecting rods 10 are arranged in a cross shape, and the connecting rods 10 are smooth round rods with large gaps between them to facilitate the passage of lubricating oil and avoid affecting the flow of lubricating oil.

[0033] In one embodiment, two sets of clamping rings 11 are arranged to improve clamping stability. The surface of the clamping rings 11 is roughened to increase friction. The clamping rings 11 adopt an arc-shaped structure to increase the contact area with the oil inlet. The rough surface of the clamping rings 11 improves the stability of clamping the outer wall of the oil inlet, thereby improving the stability of fixing and the stability of use.

[0034] In one embodiment, the distance between the bottom opening of the connector tube 2 and the bottom opening of the connector cover 3 is not less than 5cm. The bottom opening of the connector cover 3 abuts against the top surface of the oil box. The inner diameter of the connector cover 3 is larger than the outer diameter of the oil inlet, so that it can be easily fitted to the outside of the oil inlet. The outer diameter of the connector tube 2 is smaller than the inner diameter of the oil inlet, so that it can easily pass through the oil inlet and enter the oil box.

[0035] Working principle:

[0036] When adding lubricating oil to the gearbox lubrication oil tank, the bottom of the connector pipe 2 can be inserted into the lubrication oil tank through the oil filling port. At this time, the connector cover 3 is located outside the oil filling port. The operator can rotate the handle bolt 4 to move the clamping plate to clamp the oil filling port, thereby fixing the connector cover 3 and the connector pipe 2, and then fixing the oil filling hopper 1. The operator can then manually add lubricating oil into the oil filling hopper 1 to complete the lubrication oil filling process. During the manual filling process, the connector pipe 2 and the oil filling hopper 1 are fixed, preventing them from falling or tilting, thus ensuring greater stability and avoiding lubricating oil leakage. The system improves operational stability, eliminates the need for manual handling, and enhances ease of use. Simultaneously, the float 9, inserted into the lubricating oil tank, floats on top of the lubricating oil. As lubricating oil is continuously added, the float 9 gradually rises with the liquid level. Operators can observe the scale 7 to determine the amount added, avoiding overfilling or underfilling. Furthermore, when the float 9 rises to the point of blocking the bottom of the connector pipe 2, lubricating oil cannot further enter the lubricating oil tank, preventing accidental overfilling and leakage, further improving ease of use and stability.
