Description

Technical Field

[0001] This utility model belongs to the technical field of control devices for lubrication systems, and specifically relates to an adaptive quantitative lubrication device based on position sensing. Background Technology

[0002] The position-sensing-based adaptive quantitative lubrication device is an intelligent lubrication system that dynamically adjusts the amount and frequency of lubricant injection by monitoring the movement position of equipment in real time (such as the joint angle of a robotic arm, the displacement of the guide rail, etc.) and combining this with operating data. Its core lies in using high-precision sensors (such as encoders or laser rangefinders) to achieve position feedback, which, in conjunction with the control system, enables precise point-to-point lubrication. It is suitable for industrial scenarios requiring dynamic lubrication, such as CNC machine tools and wind power equipment, and can significantly reduce lubrication waste and extend equipment life.

[0003] Currently, under high-temperature operating conditions, carbonized deposits will form at the outlet of the lubrication nozzle due to the oxidation of grease caused by heat. These hardened coke deposits will gradually adhere to the inner wall of the nozzle, causing the orifice to shrink or even become completely blocked. In the early stage, this phenomenon is manifested as a slow increase in oil injection pressure, but conventional pressure monitoring is difficult to predict, eventually leading to lubrication failure.

However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0028] Example

[0029] Reference Figures 1-5 This is an embodiment of the present invention, which provides an adaptive quantitative lubrication device based on position sensing, comprising:

[0030] The support mechanism 100 includes an oil reservoir 110 for storing lubricating oil;

[0031] The lubrication mechanism 200 includes a joint bending arm 210, an anti-clogging oil outlet assembly 220 disposed at one end of the joint bending arm 210, and a cooling assembly 230 disposed outside the anti-clogging oil outlet assembly 220.

[0032] The modular design of the bearing mechanism 100 and the lubrication mechanism 200 enables a separate layout for lubricating oil storage and precise injection, facilitating maintenance and replacement. The articulated bending arm 210 can adapt to complex spatial trajectory movements. The cooperation between the anti-clogging oil outlet component 220 and the cooling component 230 effectively solves the problem of carbon buildup on the nozzle 221 under high-temperature conditions. The overall structure is adaptable to various lubrication scenarios such as machine tool guideways and robot joints.

[0033] Specifically, the anti-clogging oil outlet assembly 220 includes a nozzle 221 fixedly installed at the end of the articulated bending arm 210, a sleeve 222 fixedly installed in the inner cavity of the nozzle 221, a spiral blade 223 hinged in the inner cavity of the sleeve 222, a connecting rod 224 fixedly installed on the outside of the spiral blade 223, and a bolt 225 installed at the end of the connecting rod 224. The anti-clogging oil outlet assembly 220 also includes a support rod 226 fixedly installed at the end of the connecting rod 224 by bolt 225, an outer scraper 227 fixedly installed on one side of the support rod 226, an inner scraper 228 fixedly installed on one side of the support rod 226 and close to the outer scraper 227, and an oil outlet 229 opened at the connection between the sleeve 222 and the inner cavity of the nozzle 221.

[0034] The design employs a spiral blade 223 hinged to the sleeve 222. When lubricating oil passes through, it drives the blade to rotate, which in turn drives the scraping mechanism to move synchronously via the connecting rod 224. This achieves real-time self-cleaning of the inner wall of the nozzle 221, avoiding the gradual clogging caused by grease residue in traditional fixed nozzles. The double-layer scraping structure of the outer scraper 227 and the inner scraper 228 covers the entire circumference of the inner cavity of the nozzle 221. Combined with the rigid fixation of the support rod 226, it ensures uniform transmission of scraping force and effectively removes the formed carbonized layer. The stepped design of the oil outlet 229 reduces the grease flow rate and minimizes splashing.

[0035] Furthermore, the cooling assembly 230 includes a mounting base 231 fixedly mounted on the outside of the nozzle 221, and a miniature compressor 232 fixedly mounted on one side of the mounting base 231. The cooling assembly 230 also includes an air outlet pipe 233 fixedly mounted on the other side of the mounting base 231, and a blower head 234 fixedly mounted on the end of the air outlet pipe 233.

[0036] The fixed base 231 and the micro compressor 232 constitute a compact air-cooling system, which directly provides forced convection heat dissipation to the high-temperature area of ​​the nozzle 221, significantly slowing down the oxidation and coking speed of grease. The air outlet 233 and the blower head 234 adopt a ring array layout to form a uniform air curtain around the nozzle 221, avoiding the cooling dead corner caused by traditional single-point blowing. At the same time, the oblique design of the blower head 234 can simultaneously blow away the splashed grease around the nozzle.

[0037] Preferably, the support mechanism 100 also includes a pump 120 fixedly installed on the outside of the oil storage pipe 110, and a connecting pipe head 130 fixedly installed on the other side of the oil storage pipe 110.

[0038] The separate installation structure of the pump 120 and the connecting pipe head 130 not only ensures the stability of high-pressure oil transportation, but also allows for pipeline maintenance through quick disassembly of the connecting pipe head 130. The external design of the pump 120 avoids vibration transmission to the oil storage pipe 110, which would affect the accuracy of oil quantity measurement.

[0039] Furthermore, the lubrication mechanism 200 also includes a connector 240 fixedly installed at the other end of the articulated bending arm 210, and a delivery pipe 250 fixedly installed on the outside of the connector 240. One end of the delivery pipe 250 is fixedly connected to the bottom of the pump 120, thereby fixing the articulated bending arm 210.

[0040] The delivery pipe 250 is flexibly connected to the articulated bending arm 210 via the connector 240, allowing the pipe to remain untwisted during multi-degree-of-freedom movement of the arm; its rigid connection to the pump 120 ensures no loss of oil supply pressure.

[0041] During use, the lubricating oil stored in the oil storage pipe 110 is pressurized by the pump 120 and then delivered to the lubrication mechanism 200 through the connecting pipe head 130 and the delivery pipe 250. When the lubricating oil flows through the anti-clogging oil outlet component 220, the oil pressure drives the spiral blade 223 to rotate, which drives the connecting rod 224 and the outer scraper 227 and the inner scraper 228 to clean the inner wall of the nozzle 221 in real time. At the same time, the micro compressor 232 of the cooling component 230 continuously provides forced air cooling to the nozzle 221 through the air outlet pipe 233 and the air blower head 234. The articulated bending arm 210 can automatically adjust the angle according to the position change of the lubrication point to ensure that the lubricating oil is accurately sprayed to the target position through the oil outlet 229 of the nozzle 221, thus completing the adaptive quantitative lubrication operation.

[0042] In summary, the bearing mechanism 100 includes an oil storage pipe 110, a pump 120, and a connecting pipe head 130 to realize the storage and delivery of lubricating oil; the lubrication mechanism 200 connects the anti-clogging oil outlet component 220 and the cooling component 230 through the articulated bending arm 210 to ensure precise lubrication; the anti-clogging oil outlet component 220 consists of a nozzle 221, a sleeve 222, a spiral blade 223, etc., forming a self-cleaning system; the cooling component 230 forms an efficient heat dissipation system through components such as a fixed base 231, a micro compressor 232, and an air outlet pipe 233; the entire device is flexibly connected through a connector 240 and a delivery pipe 250, which not only ensures the smooth flow of lubricating oil but also adapts to complex motion requirements, effectively solving the technical problems of easy clogging, poor heat dissipation, and difficult maintenance of traditional lubrication devices, and is suitable for lubrication needs under harsh working conditions such as high temperature and high vibration.
