Description

Technical Field

[0001] The present invention relates to the field of mechanical technology, and particularly to an intelligent micro-lubrication device. Background Art

[0002] The cutting fluid ejected by the micro-lubrication system mainly plays two roles in metal cutting. One is the lubrication role; the other is the cooling role. Whether the cutting fluid can fully play an effective lubrication role, its penetration ability is an important factor. The penetration of conventional pouring cutting fluid in cutting processing is carried out in two ways: liquid penetration and gas penetration. Since most existing machine tools use a large amount of lubricant when using a lubrication device and cause waste, an intelligent micro-lubrication device is introduced to improve the utilization rate of the lubricant.

[0003] In the prior art, since the lubricant dose provided by the intelligent micro-lubricator is small, but the iron chips generated during the operation of the cutting tool will fly everywhere, which will impact the output environment of the output end at the bottom of the intelligent micro-lubricator, thereby causing partial blockage to the ejection amount of the nozzle, making the lubricant dose smaller, resulting in a slower falling speed of the lubricant, and thus affecting the lubrication effect of the overall intelligent micro-lubricator.

[0015] The present invention provides an intelligent micro lubrication device. It has the following beneficial effects: (1). The intelligent micro-lubrication device is provided with a lubrication device. When the cutting tool starts to rotate for cutting work, the splashing iron filings will hit the rotating baffle and be blocked. The impact force generated by the impact of the iron filings will push the rotating baffle to rotate. At the same time, the elastic force of the elastic airbag will cause the rotating baffle to swing reciprocally, which can promote the falling speed of the lubricant on the rotating baffle. At the same time, through the action of the diversion groove, the dispersed lubricant can be polymerized and the vibrating ball and the knocking rod can impact each other, comprehensively improving the sliding speed of the lubricant.

[0016] (2). The intelligent micro-lubrication device is provided with a grinding device. When the rotating baffle rotates, the rotating baffle can drive the slider to move upward in an arc through the arc-shaped connecting rod.

[0017] (3). The intelligent micro-lubrication device is provided with an auxiliary device. When the grinding block slides left and right due to the reciprocating ejection of the ejector rod, the rotating pressing plate inside the grinding block will move in the opposite direction to the grinding block due to inertia. The rotating pressing plate can drive the pressing plate to compress the elastic balloon, and the compressed elastic balloon generates air flow that flows out through the blowing pipe, thereby cleaning the debris generated after grinding the cutting tool and improving the grinding efficiency.

[0018] (4). The intelligent micro-lubrication device is provided with spherical protrusions on the pressing plate. When the pressing plate compresses the elastic balloon, the spherical protrusions can increase the contact area between the pressing plate and the elastic balloon to improve the compression effect. At the same time, the movement of the pressing plate can drive the blowing pipe to swing through the spring rod, improving the blowing range.

[0019] (5). The intelligent micro-lubrication device is provided with a vibration device. When the rotating baffle swings reciprocally, the rotating baffle can push the Y-shaped connecting rod upward through the telescopic plate and the connecting plate. The Y-shaped connecting rod can drive the extrusion cylinder to extrude the vibrating elastic rod to generate a contraction slide, so that the vibrating elastic rod can drive the vibrating circular block to slide and knock and vibrate the bottom of the filter plate, preventing blockage, promoting the falling of the lubricant, and improving the utilization rate of the lubricant.

The bottom of the spring rod 72 is rotatably installed on the outer wall of the blowing pipe 63. The spring rod 72 passes through and is slidably installed on the grinding block 56. By providing the grinding device, when the rotating baffle 34 rotates, the rotating baffle 34 can drive the ejector rod 54 to move upward through the arc-shaped connecting rod 51, and the ejector rod 54 can then push the grinding block 56 towards the cutting knife 1 for grinding operation, improving the cutting effect of the cutting knife 1.

[0025] As Figure 2 and Figure 6As shown, in the present invention, a vibration device is provided on the splash guard 33. The vibration device includes a telescopic plate 81. One end of the telescopic plate 81 is rotatably installed on the outer wall of the rotating baffle 34, and the other end of the telescopic plate 81 is slidably installed on the connecting plate 82. Both the telescopic plate 81 and the connecting plate 82 are slidably installed on the outer wall of the splash guard 33. The top of the connecting plate 82 is fixedly installed at the bottom of the Y-shaped connecting rod 83. The top of the Y-shaped connecting rod 83 is fixedly installed with an extrusion cylinder 84. A bracket 86 is fixedly installed on the bottom outer wall of the intelligent micro-lubricator 31. A vibration elastic rod 85 is penetrated and slidably installed on the bracket 86. The vibration elastic rod 85 is made of rubber material and has elastic telescopic property. The top of the extrusion cylinder 84 is arranged close to the outer wall of the bottom edge of the vibration elastic rod 85. The top of the vibration elastic rod 85 is fixedly installed with a vibration block 87. The bottom output end of the intelligent micro-lubricator 31 is fixedly installed with a filter plate 9. The top of the vibration block 87 is arranged close to the outer wall of the bottom of the filter plate 9. By providing the vibration device, when the rotating baffle 34 swings reciprocally, the vibration elastic rod 85 can drive the vibration block 87 to slide and knock and vibrate the bottom of the filter plate 9 to prevent blockage, promote the dropping of the lubricant, and improve the utilization rate of the lubricant.

[0026] During operation (or use), when the cutting tool 1 starts to rotate for cutting work, the splashing iron filings will impact on the rotating baffle 34 and be partially blocked by the rotating baffle 34 and the splash guard 33. At the same time, the rotating baffle 34 can intercept and aggregate the dispersed micro-lubricant sprayed by the intelligent micro-lubricator 31. The impact force generated by the impact of the iron filings will push the rotating baffle 34 to rotate. At the same time, the elastic force of the elastic airbag 35 will cause the rotating baffle 34 to swing reciprocally, thereby promoting the falling speed of the lubricant on the rotating baffle 34. At the same time, through the action of the diversion groove 41, the dispersed lubricant can be aggregated. Subsequently, during the process of the elastic airbag 35 being compressed and deformed, the elastic airbag 35 can drive the vibrating ball 44 to slide on the diversion groove 41 through the knocking rod 43, so that the vibrating ball 44 can impact and vibrate with the inclined protrusion 42 on the diversion groove 41, causing the rotating baffle 34 to perform a slight vibration operation, promoting the flow of the lubricant inside the diversion groove 41, and ultimately comprehensively improving the sliding speed of the lubricant; by setting a grinding device, when the rotating baffle 34 rotates, the rotating baffle 34 can drive the slider 52 to move upward in an arc through the arc-shaped connecting rod 51. By sliding the slider 52 on the slide plate 53, the slide plate 53 can slide linearly upward along the outer wall of the intelligent micro-lubricator 31. The slide plate 53 can drive the ejector rod 54 to move upward, and the ejector rod 54 can push the grinding block 56 out towards the cutting tool 1 through the inclined surface of the grinding block 56 for grinding operation to improve the cutting effect of the cutting tool 1. By setting an auxiliary device, when the grinding block 56 slides left and right due to the reciprocating lifting of the ejector rod 54, the rotating pressing plate 64 inside the grinding block 56 will move in the opposite direction to the grinding block 56 due to inertia. The rotating pressing plate 64 can drive the pressing plate 65 to compress the elastic balloon 62. The elastic balloon 62 is compressed to generate air flow that flows out through the blowing pipe 63, thereby cleaning the debris generated during and after grinding the cutting tool 1 and improving the grinding efficiency. By setting a spherical protrusion 71 on the pressing plate 65, when the pressing plate 65 compresses the elastic balloon 62, the spherical protrusion 71 can increase the contact area between the pressing plate 65 and the elastic balloon 62 to improve the compression effect. At the same time, the movement of the pressing plate 65 can drive the blowing pipe 63 to swing through the spring rod 72, improving the blowing range;By providing a vibration device, when the rotating baffle 34 swings reciprocally, the rotating baffle 34 can push the Y-shaped connecting rod 83 upward through the telescopic plate 81 and the connecting plate 82. Then, the Y-shaped connecting rod 83 can drive the extrusion cylinder 84 to extrude the vibration elastic rod 85 to cause shrinkage and sliding, so that the vibration elastic rod 85 elastically contracts on the bracket 86. Thus, the vibration elastic rod 85 can drive the vibration round block 87 to slide and knock on the bottom of the filter plate 9 to prevent blockage, promote the dropping of the lubricant, and improve the utilization rate of the lubricant. In summary, by providing a lubrication device, when the cutting tool 1 starts to rotate for cutting work, the splashing iron filings will hit the rotating baffle 34 and be blocked. The impact force generated by the impact of the iron filings will push the rotating baffle 34 to rotate. At the same time, the elastic force of the elastic airbag 35 will cause the rotating baffle 34 to swing reciprocally, thereby promoting the falling speed of the lubricant on the rotating baffle 34.;
