Description

Technical Field

[0001] This utility model relates to the field of micro-lubricating air circuit technology, and in particular to a novel micro-lubricating air circuit device. Background Technology

[0002] With increasing environmental awareness and higher requirements for machining precision, micro-lubrication technology has emerged. The micro-lubrication air circuit device is one of the key pieces of equipment for realizing this technology. It mixes a small amount of lubricant with compressed air to form micron-sized oil mist particles, which are then precisely delivered to the cutting area to lubricate the tool and workpiece. This method effectively reduces tool wear, improves machining accuracy, and significantly reduces the amount of lubricant used, thus reducing environmental pollution. However, the compressed air for micro-lubrication is installed after the lubricating oil, resulting in a large amount of lubricating oil in the compressed air. During finish machining, this oil contaminates the product surface, causing numerous pits and affecting product quality.

[0003] To prevent the lubricating oil from replenishing the cylinder from entering the compressed air for micro-lubrication, thereby reducing lubricant usage, saving processing costs, and contaminating the product, a new type of micro-lubrication air circuit device needs to be designed. Utility Model Content

[0004] The purpose of this invention is to provide a novel micro-lubrication air circuit device to solve the defect of existing novel micro-lubrication air circuit devices where the lubricating oil in the supplementary cylinder enters the compressed air with micro-lubrication.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a novel micro-lubricating air circuit device, including a frame;

[0006] An instrument panel is fixed on one side of the outer wall of the frame, and a compressed air pipe is fixed at one end of the frame near the instrument panel. A connecting pipe is fixed at the bottom end of the compressed air pipe.

[0007] Lubricating oil tanks are fixed on both sides of the bottom end of the frame. A limiting structure is fixed at the bottom end of each lubricating oil tank. The limiting structure includes a connecting block fixed to the bottom end of the lubricating oil tank. Limiting plates are provided on both sides of the connecting block. A fixing bolt passes through the inside of each connecting block. A limiting bolt passes through the bottom of each limiting plate.

[0008] The inner side of each limiting plate is provided with a lubricating oil pipe, and the end of the lubricating oil pipe near the connecting pipe is provided with a sealing structure.

[0009] Furthermore, the sealing structure includes a sealing groove, a sealing ring, and a deformation groove. The sealing groove is formed on the outer wall of the lubricating oil pipe near the connecting pipe. The sealing ring is provided inside the sealing groove, and the deformation groove is formed inside the sealing ring.

[0010] Furthermore, the sealing ring and the lubricating oil pipe are connected by an interference fit through a sealing groove, and one side of the sealing ring and one side of the connecting pipe are fixedly connected.

[0011] Furthermore, one end of the lubricating oil pipe and one side of the connecting pipe are fixedly connected by bolts.

[0012] Furthermore, both ends of the fixing bolt extend to the outside of the limiting plate, which is symmetrically distributed on both sides of the instrument panel.

[0013] Furthermore, the inner wall of the limiting plate and the outer wall of the lubricating oil pipe are in contact with each other.

[0014] Furthermore, the limiting plates are symmetrically distributed on both sides of the frame.

[0015] The novel micro-lubricating air circuit device provided by this utility model has the following advantages:

[0016] By installing a lubricating oil pipe and placing the compressed air for micro-lubrication before the lubricating oil, the lubricating oil for replenishing the cylinder no longer enters the compressed air for micro-lubrication, thus preventing product contamination. This device achieves the function of preventing lubricating oil from entering the compressed air and improves the working efficiency of this new micro-lubrication air circuit device during use.

[0017] By setting a limiting structure, the limiting plate can be fixed on both sides of the connecting block under the connection of the fixing bolt. Before fixing the limiting plate, the lubricating oil pipe is placed inside the limiting plate. The limiting plate can limit the lubricating oil pipe. The fixing action of the limiting bolt can ensure that the limiting plate is stably installed on both sides of the lubricating oil pipe, stably limiting the lubricating oil pipe and preventing the lubricating oil pipe from shaking during use. This realizes that the device has the function of conveniently limiting the lubricating oil pipe and improves the stability of the new micro-lubricating air circuit device during use.

[0018] By incorporating a sealing structure, the sealing groove can be sealed by the interference fit between the sealing ring and the frame, ensuring the airtightness of the connecting pipe and the lubricating oil pipe when they are connected. After the connecting pipe and the lubricating oil pipe are fixed together by bolts, the sealing ring is compressed and deformed. The deformed sealing ring and the inner wall of one end of the lubricating oil pipe come into contact with each other, which can enhance the airtightness. The deformation groove is used to enhance the elastic deformation capacity of the sealing ring and improve the airtightness. This device enables easy sealing of the connecting pipe and the lubricating oil pipe, improving the working efficiency and convenience of this new micro-lubricating air circuit device.

[0027] Reference Figures 1-5 An instrument panel 2 is fixed on the outer wall of one side of the frame 1. A compressed air pipe 3 is fixed at one end of the frame 1 near the instrument panel 2. A connecting pipe 4 is fixed at the bottom end of the compressed air pipe 3. Lubricating oil tanks 8 are fixed on both sides of the bottom end of the frame 1. A limiting structure 7 is fixed at the bottom end of each lubricating oil tank 8. The limiting structure 7 includes a connecting block 71 fixed to the bottom end of the lubricating oil tank 8. A limiting plate 73 is provided on both sides of the connecting block 71. A fixing bolt 72 passes through the inside of the connecting block 71. A limiting bolt 74 passes through the bottom of each limiting plate 73. Both ends of the fixing bolt 72 extend to the outside of the limiting plate 73.

The inner wall of the limiting plate 73 and the outer wall of the lubricating oil pipe 6 are in contact with each other. The limiting plates 73 are symmetrically distributed on both sides of the frame 1.

[0028] When installing and limiting the lubricating oil pipe 6, use the fixing bolt 72 to pre-limit the limiting plate 73 on both sides of the connecting block 71. With the limiting plate 73 in a loose state, place the lubricating oil pipe 6 inside the limiting plate 73. Then use the fixing bolt 72 to fix the limiting plate 73 and the connecting block 71 together. Then insert the limiting bolt 74 into the bottom of the limiting plate 73 and tighten it so that the bottom of the limiting plate 73 can be firmly fixed together to prevent the lubricating oil pipe 6 from falling off.

[0029] Reference Figure 1 , Figure 2 and Figure 4 The inner side of the limiting plate 73 is provided with a lubricating oil pipe 6. The end of the lubricating oil pipe 6 near the connecting pipe 4 is provided with a sealing structure 5.

The sealing groove 51 is opened on the outer wall of the lubricating oil pipe 6 near the connecting pipe 4. The sealing ring 52 is provided inside the sealing groove 51. The deformation groove 53 is opened inside the sealing ring 52. The sealing ring 52 and the lubricating oil pipe 6 are connected by interference fit through the sealing groove 51.

[0030] When fixing the connecting pipe 4 and the lubricating oil pipe 6, the sealing ring 52 on one side of the connecting pipe 4 is inserted into the sealing groove 51 on one side of the lubricating oil pipe 6, so that the sealing ring 52 and the lubricating oil pipe 6 are connected by interference fit through the sealing groove 51, which improves the airtightness of the connection between the connecting pipe 4 and the lubricating oil pipe 6.
