Technical Field

[0002] Gear oiling is one of the gear processing processes. For a few gears, oil is applied manually between two gears after assembly to reduce the friction between the two gears.

[0003] There are also methods in the prior art for automating the oiling process between two gears. For example, the authorization announcement number CN204933881U discloses an oiling table for detecting gear oiling in a steering wheel power steering system. In this utility model, the gears are mainly placed horizontally, and then driven by an X-axis drive mechanism, a Y-axis drive mechanism and a Z-axis drive mechanism, the gears are rotated around the circumferential wall of the magnetic column on the first gear and oiled. Although this operation realizes the automation of the oiling process, since the lubricating oil cannot be evenly distributed on the intersecting surface between the two gears, problems such as uneven oiling and poor anti-friction effect occur.

[0004] Meanwhile, the gear oiling in the prior art is generally only applied horizontally around the gear, and the application is uneven, which results in incomplete lubrication after the two gears are meshed.

DETAILED DESCRIPTION

[0062] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, and therefore only show the components related to the present invention. Example

[0063] See also Figure 1-Figure 9 An embodiment of the present invention provides a gear oiling device, comprising: an oiling rack 100, a gear clamping assembly 200, a three-axis robotic arm 300 and an oiling assembly 400; the three-axis robotic arm is fixedly arranged on the oiling rack 100; the gear clamping assembly 200 is arranged at the end of the three-axis robotic arm 300, and is suitable for clamping the gear; the gear clamping assembly 200 is suitable for driving the gear to rotate; the oiling assembly 400 is suitable for applying lubricating oil to the rotating gear clamped by the gear clamping assembly 200 in a wave shape. Through the newly designed oiling component 400, the gears are lubricated in a wave shape, so that after the two gears are meshed, the two gears twist the lubricating oil, and the lubrication effect on the gears is better. At the same time, in order to avoid the lubricating oil being sprayed on the gear clamping component 200, resulting in waste of lubricating oil, the oil spray nozzle 450 of the oiling component 400 needs to be lower than the gear. The oiling component 400 provided by the present invention can minimize the distance between the oil spray group and the gear, thereby maximizing the application range of the gear and improving the application effect of the gear lubricating oil.

[0064] In this embodiment, the oiling assembly 400 includes: an oil injection motor 410, a vertical plate 420, a rotating disk 430, a lifting plate 440 and an oil injection nozzle 450; the rotating disk 430 is rotatably arranged on the vertical plate 420 and is driven by the oil injection motor 410; the lifting plate 440 is slidably arranged on the vertical plate 420; the oil injection nozzle 450 is fixedly arranged on the lifting plate 440; the lifting plate 440 abuts against the upper top surface of the rotating disk 430; the rotor axis of the oil injection motor 410 is eccentric to the rotating disk 430. Setting: the oil injection motor 410 is suitable for driving the rotating disk 430 to rotate, thereby driving the lifting plate 440 to lift and lower back and forth; the three-axis mechanical arm is suitable for driving the gear clamped by the gear clamping assembly 200 to be opposite to the oil injection nozzle 450; after the oil injection motor 410 works, and when the oil injection nozzle 450 is opposite to the gear clamped by the gear clamping assembly 200, the gear clamping assembly 200 is controlled to drive the gear to rotate, and the oil injection nozzle 450 is opened, at this time, the oil injection nozzle 450 will apply lubricating oil to the gear in a wave shape. The lifting and lowering of the vertical plate 420 drives the oil spray nozzle 450 to lift and lower, and the two are overlapped with the rotation of the gear shaft. At this time, the path of the oil spray nozzle 450 after spraying oil on the gear is wavy, which can minimize the distance between the oil spray group and the gear, thereby maximizing the application range of the gear and improving the application effect of the gear lubricant. At the same time, when the lifting plate 440 is driven by the rotating disk 430, there is a slight air dwell time, that is, the thrust of the rotating disk 430 on the lifting plate 440 is equal to the gravity of the rotating disk 430. At this time, the lifting plate 440 will be suspended in the air, so that more lubricant is sprayed on the wave crest. After the two gears are meshed, the gear oil can extend upward, so that the lubricant application range of the gear rack is larger.

[0065] At the same time, the spraying method using the rotating disk 430 and the lifting plate 440 can make the lubricating oil spraying more accurate, avoiding the waste of lubricating oil. At the same time, compared with controlling the lifting of the three-axis robotic arm 300, the number of times the three-axis robotic arm 300 is used is reduced, thereby increasing the service life of the three-axis robotic arm 300.

[0066] In this embodiment, the abutting surface between the lifting plate 440 and the rotating disk 430 is an inwardly concave arc, and a plurality of adjustment slots 441 are provided on the arc-shaped abutting surface of the rotating disk 430; the oiling assembly 400 further includes an adjustment rod 445; one end of the adjustment rod 445 is adapted to be inserted into the adjustment slot 441, and the other end is adapted to be abutted against the rotating disk 430; thereby adjusting the initial height of the lifting plate 440, and then spraying oil on gears of different thicknesses. By inserting the adjustment rod 445 into the adjustment slots 441 of different arcs, the rising height of the lifting plate 440 can be adjusted, thereby meeting the oiling requirements of gears of different thicknesses.

[0067] Specifically, the lengths of the adjustment grooves 441 are different, and after the adjustment rod 445 is adapted to different adjustment grooves 441, the lengths of the protruding adjustment grooves 441 are also different, that is, the gaps between the lifting plate 440 and the rotating disk 430 are different, so as to adjust the initial height of the lifting plate 440, thereby meeting the oil injection requirements of gears of different thicknesses.

[0068] In this embodiment, in order to realize the lifting and lowering of the lifting plate 440, a sliding groove 421 is opened at the top of the vertical plate 420, and a sliding block 442 is slidably arranged in the sliding groove 421. The lifting plate 440 is fixedly connected to the sliding block 442. When the rotating disk 430 rotates, the rotating disk 430 pushes the lifting plate 440 to rise and fall, so that the sliding block 442 slides along the sliding groove 421.

[0069] In order to ensure the lifting stability of the lifting plate 440, a relative limit groove 422 is opened on the inner wall of the sliding groove 421. At the same time, limit blocks 443 are respectively arranged on both sides of the sliding block 442. The limit blocks 443 cooperate with the limit groove 422 to limit the sliding of the sliding block 442.

[0070] It should be pointed out that after the fuel injector 450 finishes spraying, the fuel injector 450 remains in a horizontal state. At this time, some lubricating oil is retained in the internal oil circuit of the fuel injector 450. In order to discharge the retained lubricating oil, the fuel injector 450 needs to be tilted forward to use gravity to discharge the lubricating oil in the fuel injector 450 while avoiding the residual solidification of the lubricating oil on the lower end surface of the fuel injector 450.

[0071] In order to achieve the forward tilt of the fuel injector 450, that is, the forward tilt of the lifting plate 440, an inclined groove 423 is further provided in the sliding groove 421. When the sliding block 442 slides upward, after the sliding block 442 slides to the bottom and is located in the inclined groove 423 area, the fuel injector 450 and the lifting plate 440 tilt forward because the overall center of gravity formed by the fuel injector 450 and the lifting plate 440 is forward.

[0072] In order to ensure that the sliding block 442 can move back after sliding upward and leaning forward, a return spring 444 is provided at the bottom of the sliding block 442. During the lifting process of the sliding block 442, the return spring 444 is stretched. After the sliding block 442 loses the power to lift, the return spring 444 restores its deformation and pulls the sliding block 442 back into the sliding groove 421.

[0073] In order to ensure that the injector 450 can tilt forward, a firing groove 446 is opened on the side of the limit block 443 away from the inclined groove 423, and a firing spring 447 and a firing push block 448 are arranged in the firing groove 446. After the limit block 443 is lifted to the area of ​​the inclined groove 423, the firing spring 447 rebounds and pushes the firing push block 448 to push the side wall of the limit groove 422, so that the sliding block 442 tilts forward to one side of the inclined groove 423.

[0074] In order to realize the lifting and lowering or forward tilting of the lifting plate 440, it is necessary to adjust the eccentricity of the rotating disk 430. The different eccentricities of the rotating disk 430 can realize the adjustment of the lifting stroke of the lifting plate 440. A radially arranged stroke groove 431 is provided on the end surface of the rotating disk 430, and positioning grooves 432 are respectively provided at both ends of the side walls of the stroke groove 431. A stroke block 411 is provided at the output end of the injection motor 410. The stroke block 411 is adapted to slide with the stroke groove 431, and a positioning block 412 corresponding to the positioning groove 432 is provided on the stroke block 411. The stroke block 411 slides in the stroke groove 431 to make the eccentricity of the rotating disk 430 different, thereby adjusting the lifting stroke of the lifting plate 440.

[0075] In this embodiment, the oiling assembly 400 further includes an oil receiving platform 460 and an oil receiving barrel 470; the oil receiving platform 460 is fixedly arranged on the vertical plate 420; and the oil receiving barrel 470 is embedded in the oil receiving platform 460. The lubricating oil sliding off the gear is received by the oil receiving barrel 470, thereby avoiding the waste of lubricating oil. The received lubricating oil can also be poured into the lubricating oil adding tank for continued use, thereby reducing the overall cost of gear lubrication and improving economic benefits.

[0076] In this embodiment, the three-axis robot arm 300 is suitable for rising and falling along with the wave crests and troughs of the wave-shaped oiling process of the oiling assembly 400. By controlling the three-axis robot arm 300 to rise and fall slightly, more lubricating oil can be sprayed on the wave crests, so that the gears are extended closer to the upper end of the gears after meshing, thereby improving the overall lubrication effect.

[0077] In this embodiment, the three-axis robot 300 is suitable for following the lifting process along with the wave crests and troughs of the wave-shaped oiling of the gear by the oiling component 400, that is; when the lifting plate 440 completes a lifting, the three-axis robot 300 drives the gear to complete a lifting, thereby deepening the height of the wave crests and troughs of the wave ripples; and the height of the oil nozzle 450 shall not exceed the height of the upper end of the rack of the gear.

[0078] In this embodiment, the gear clamping assembly 200 includes a connecting ring 210, a plurality of clamping claws 220 and a pneumatic drive unit; the plurality of clamping claws 220 are hinged on the connecting ring 210 and are arranged along the circumference of the connecting ring 210; the pneumatic drive unit is suitable for driving the plurality of clamping claws 220 to open or close, thereby completing the clamping and release of the gear.

[0080] In this embodiment, the three-axis robotic arm 300 includes an X-axis driving unit 310, a Y-axis driving unit 320 and a Z-axis driving unit 330; the X-axis driving unit 310 is slidably set on the oil coating rack 100; the Y-axis driving unit 320 is slidably set on the X-axis driving unit 310; the Z-axis driving unit 330 is slidably set on the Y-axis driving unit 320; the gear clamping assembly 200 is fixedly set below the Z-axis driving unit 330.

At the same time, in order to avoid the lubricating oil being sprayed on the gear clamping component 200, resulting in waste of lubricating oil, the oil spray nozzle 450 of the oiling component 400 needs to be lower than the gear.
