[0002] The wheel hub is the rotating part of the wheel core connected to the inner profile of the tire by a column, that is, the metal part that supports the center of the tire and is mounted on the shaft. It is also called a rim, steel rim, wheel, or tire bell. The wheel hub is divided into different types according to diameter, width, molding method, and material. During the production and processing of the wheel hub, drilling equipment is required to drill holes in the wheel hub to facilitate subsequent processing and assembly of the wheel hub.

[0018] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Please refer to Figures 1 - 10, the present invention provides a technical solution: a drilling device for processing automobile wheels, including a base 1, a double-axis moving seat 2 and a vertical moving mechanism 3 arranged on the top of the base 1, a transmission mechanism 4 arranged on the vertical moving mechanism 3, a clamping mechanism 5 arranged on the top of the double-axis moving seat 2, and a filtering mechanism 6 arranged below the base 1. The vertical moving mechanism 3 is arranged at the edge of the top of the base 1, and the double-axis moving seat 2 is arranged on the side away from the edge of the vertical moving mechanism 3. The double-axis moving seat 2 is used to drive the wheel clamped and fixed by the clamping mechanism 5 to move closer to or away from the vertical moving mechanism 3 along the length direction of the top of the base 1, and to move in the vertical direction close to or away from the vertical moving mechanism 3. The vertical moving mechanism 3 is used to drive the transmission mechanism 4 to move closer to or away from the wheel clamped by the clamping mechanism 5 in the vertical direction and to drill and cool the wheel. The filtering mechanism 6 is used to collect and filter the coolant.

[0020] It should be noted that the double-axis moving seat 2 can be a transmission structure driven by a motor and a lead screw, or a structure driven by the telescopic movement of a cylinder or a hydraulic cylinder.

[0021] Specifically, as Figure 1 shown, a liquid collecting tray 11 is fixedly connected to the top of the base 1. A filter hole 12 is arranged at the bottom of the side of the liquid collecting tray 11 away from the vertical moving mechanism 3. The liquid collecting tray 11 is used to collect the coolant used for cooling during drilling processing, and the filter hole 12 is used to preliminarily filter and remove large-sized debris in the coolant.

[0022] Specifically, as Figure 1 and Figure 2 shown, the vertical moving mechanism 3 includes a column 31 fixed to one side edge of the top of the base 1, a driving part 35 arranged on the top of the column 31, and a transmission housing 36 arranged on the side of the column 31 away from the edge of the base 1. The column 31 is a hollow structure, and a counterweight 32 is slidably connected inside the column 31. Two groups of chains 33 are fixedly connected to the top of the counterweight 32, and the other ends of the chains 33 are fixedly connected to the top of the transmission housing 36. Two groups of sprockets 34 are connected by bearings to the top of the column 31, and each group of sprockets 34 has two. The chains 33 are meshed with the sprockets 34; The transmission housing 36 is slidably connected to the column 31, and the output end of the driving part 35 is in transmission connection with the transmission housing 36.

[0023] It should be noted that the driving part 35 preferably adopts a transmission structure driven by a motor and a lead screw. At this time, the output end of the driving part 35 is in threaded connection with the transmission housing 36.

[0024] In actual operation, the driving part 35 is started, and the driving transmission housing 36 moves up and down along the vertical direction of the column 31. Under the action of the gravity of the counterweight 32 and the meshing transmission of the chain 33 and the sprocket 34, when the driving part 35 drives the transmission housing 36 to rise, the counterweight 32 descends; when the driving part 35 drives the transmission housing 36 to descend, the counterweight 32 rises, so as to ensure that the driving part 35 can have good stability when driving the transmission housing 36 to rise and fall, which is beneficial to improving the subsequent drilling quality.

[0025] Specifically, as Figures 3 - 8 shown, the transmission mechanism 4 includes a driving motor 41, a main driving component 42, a first transmission component 43, a drilling component 44, a second transmission component 45, a driven driving component 46, two groups of adjusting components 47, a cooling component 48 and a swinging component 49. The driving motor 41 is fixed on the top of the transmission housing 36. The main driving component 42, the first transmission component 43, the drilling component 44, the second transmission component 45 and the driven driving component 46 are sequentially connected in transmission from the direction close to the vertical moving mechanism 3 to the direction far away from it. The adjusting components 47 are arranged on both sides of the transmission housing 36. The positions of the two groups of adjusting components 47 correspond to the positions of the main driving component 42 and the driven driving component 46 respectively. The adjusting component 47 is used to move the positions of the gears on the main driving component 42 and the driven driving component 46. The cooling component 48 is in transmission connection with the driven driving component 46. The swinging component 49 is arranged at the bottom of the transmission housing 36. The drilling component 44 is used for drilling. The driven driving component 46 is used to drive the cooling component 48 to rotate. The cooling component 48 is used for extracting the coolant. The swinging component 49 is used to adjust the position aligned during cooling.

[0026] Furthermore, as Figure 4 and Figure 5 shown, the main driving component 42 includes a spline shaft 421 fixedly connected to the output end of the driving motor 41, a sliding gear 422 spline-connected to the spline shaft 421, and a first gear 423 key-connected to the sliding gear 422. The spline shaft 421 is connected to the transmission housing 36 through a bearing. The first gear 423 is arranged on the periphery of the sliding gear 422. A stop nut is arranged on the sliding gear 422. The stop nut is arranged at the bottom of the first gear 423. The stop nut is used to limit the axial position of the first gear 423 on the sliding gear 422.

[0027] As Figure 4 and Figure 5 shown, the first transmission component 43 includes a second rotating shaft 431 connected to the transmission housing 36 through a bearing, and a second gear 432, a third gear 433 and a fourth gear 434 fixedly arranged on the second rotating shaft 431 from top to bottom. The third gear 433 meshes with the sliding gear 422, and the fourth gear 434 meshes with the first gear 423.

[0028] It should be noted that for the sliding gear 422 of the active drive component 42, the first gear 423, the third gear 433 of the first transmission component 43, and the fourth gear 434, the third gear 433 and the sliding gear 422 will not be meshed at the same time, nor will the fourth gear 434 and the first gear 423 be meshed at the same time.

[0029] As Figure 4 and Figure 5 shown, the drilling component 44 includes a main shaft 441 that is connected to the transmission housing 36 by bearings and a fifth gear 442 that is fixed to the main shaft 441. The fifth gear 442 is in meshing transmission with the third gear 433. A main shaft sleeve 443 is arranged on the periphery of the main shaft 441, and the main shaft sleeve 443 is fixedly connected to the transmission housing 36. A chip-breaking drill bit is connected to the bottom of the main shaft 441. The main shaft sleeve 443 is used to limit the axial displacement of the main shaft 441 and prevent coolant from penetrating into the transmission mechanism 4.

[0030] As Figures 4 - 6 shown, the second transmission component 45 has the same structure and arrangement as the first transmission component 43, and the driven drive component 46 has the same structure and arrangement as the active drive component 42. However, a first bevel gear 461 is fixedly connected to the bottom of the driven drive component 46.

[0031] As Figures 4 - 6 shown, the adjustment component 47 includes a dial 471 and a connecting rod 472. The connecting rod 472 is in a C shape and is arranged on the outer periphery of the first gear 423 in the radial direction and on both axial sides of the first gear 423. The dial 471 maintains a gap with the pitch circle of the gear 423. One end of the connecting rod 472 is connected to the dial 471 by bearings, and the other end of the connecting rod 472 is connected to a shift fork shaft 473 by bearings. A rotating handle 474 is fixedly connected to the shift fork shaft 473. The rotating handle 474 is arranged outside the transmission housing 36 and is connected to the transmission housing 36 by bearings.

[0032] It should be noted that the diameter of the first gear 423 is larger than the diameter of the sliding gear 422, and the diameter of the third gear 433 is larger than the diameter of the fourth gear 434. When the sliding gear 422 is meshed with the third gear 433, it is a speed increase, and when the first gear 423 is meshed with the fourth gear 434, it is a speed decrease.

[0033] In actual operation, rotating the rotating handle 474 counterclockwise drives the synchronous shift fork shaft 473 to rotate counterclockwise. At this time, it is a reverse rotation of the rotating handle 474, thereby driving the connecting rod 472 to rotate counterclockwise around the bearing connection with the shift fork shaft 473. Driven by the connecting rod 472, the dial 471 drives the first gear 423 on the driven drive component 46 to slide downward along the axial direction of the spline shaft 421, so that the first gear 423 on the driven drive component 46 is meshed with the fourth gear 434 on the second transmission component 45, changing the gears for the transmission of the second transmission component 45 and the driven drive component 46; After that, rotate the rotating handle 474 clockwise. At this time, when the rotating handle 474 is pushed forward, it can drive the first gear 423 on the driven drive assembly 46 to slide upward along the axial direction of the spline shaft 421. Then, the first gear 423 on the driven drive assembly 46 can be engaged with the fourth gear 434 on the second transmission assembly 45 for transmission, and it can be changed to the sliding gear 422 on the driven drive assembly 46 being engaged with the third gear 433 on the driven drive assembly 46, thereby realizing variable-speed transmission. Similarly, by pushing the paddle 471 on the adjusting assembly 47 close to the active drive assembly 42, the gears on the active drive assembly 42 and the first transmission assembly 43 can also be adjusted, so that the first gear 423 on the active drive assembly 42 is engaged with the fourth gear 434 on the first transmission assembly 43 for transmission, or the sliding gear 422 on the active drive assembly 42 is engaged with the third gear 433 on the first transmission assembly 43 for transmission, thereby facilitating the adjustment of the drilling speed and the cooling capacity.

[0034] It should be noted that in actual use, the rotating handle 474 can be driven by a motor, which can further realize automatic speed change.

[0035] As Figure 7 shown, the cooling assembly 48 includes a second bevel gear 481 meshed and connected with the first bevel gear 461 and a housing 483 fixed inside the transmission housing 36. The second bevel gear 481 is fixedly connected with a first rotating shaft 482. The first rotating shaft 482 is connected to the housing 483 by bearings. One end of the first rotating shaft 482 away from the first bevel gear 461 is fixedly connected with an impeller 486. The impeller 486 is located inside the housing 483. One axial side of the housing 483 is connected with a liquid inlet pipe 484. The liquid inlet pipe 484 corresponds to the center of the impeller 486. One radial side of the housing 483 is connected with a liquid outlet pipe 485. The liquid outlet pipe 485 is connected to the filtering mechanism 6 through a pipeline.

[0036] In actual operation, when the driven drive assembly 46 rotates, through the meshing transmission of the first bevel gear 461 and the second bevel gear 481, it can drive the first rotating shaft 482 to rotate, thereby driving the impeller 486 to rotate. Using the centrifugal force generated when the impeller 486 rotates, liquid or air is sucked from the center of the impeller 486 and the liquid inlet pipe 484. At the same time, the impeller 486 can rotate synchronously with the driven drive assembly 46.

[0037] As Figure 7 and Figure 8As shown, the swing assembly 49 includes a connector 491 connected to the liquid outlet pipe 485, and a rotating pipe 497 rotatably connected to the connector 491. The end of the rotating pipe 497 is aligned with the chip-breaking drill bit. A slide rail 492 and a cylinder 493 are fixedly connected to the bottom of the transmission housing 36. The cylinder 493 is disposed on one side of the slide rail 492. The output end of the cylinder 493 penetrates through one side of the slide rail 492. The output end of the cylinder 493 is fixedly connected to a rack 494. The rack 494 is disposed inside the slide rail 492 and is slidably connected to the slide rail 492. The rack 494 is meshed with a sixth gear 495. The sixth gear 495 is fixedly connected to a connecting shaft. The connecting shaft is connected to the transmission housing 36 by bearings. A sector gear 496 is fixedly connected to the connecting shaft. The sector gear 496 is meshed with a seventh gear 498. The seventh gear 498 is fixed on the rotating pipe 497.

[0038] During actual use, when the cylinder 493 extends, it drives the rack 494 to slide inside the slide rail 492 away from the cylinder 493. Through the meshing transmission between the rack 494 and the sixth gear 495, the sixth gear 495 can be driven to rotate counterclockwise. Since both the sixth gear 495 and the sector gear 496 are fixedly connected to the connecting shaft, the sector gear 496 can be synchronously driven to rotate counterclockwise. Also, because the sector gear 496 is meshed with the seventh gear 498, the sector gear 496 can drive the seventh gear 498 to rotate clockwise, and then the rotating pipe 497 can be driven to rotate clockwise. Conversely, when the cylinder 493 contracts, the rotating pipe 497 can be driven to rotate counterclockwise, achieving the effect of adjusting the flushing range of the coolant in the rotating pipe 497.

[0039] Specifically, as Figure 9 shown, the clamping mechanism 5 includes an electric fixture 51 fixed to the top of the double-axis moving seat 2. A plurality of jaws 52 are provided on the electric fixture 51. A plurality of springs 53 are fixedly connected to the tops of the jaws 52. A sliding sleeve 54 is slidably connected to the jaws 52. The other ends of the springs 53 are fixedly connected to the inside of the sliding sleeve 54.

[0040] During actual operation, the hub is placed on the electric fixture 51. The springs 53 contract under the gravity of the hub to ensure that the top of the sliding sleeve 54 can correspondingly support the center bottom. Then the electric fixture 51 acts, causing the jaws 52 to move away from the center of the electric fixture 51, so that the outer diameter of the jaws 52 can fit the inner diameter of the hub, supporting the hub to be drilled. At the same time, it is applicable to hubs of different sizes, improving the applicability of the drilling device.

[0041] It should be noted that preferably, the electric fixture 51 with an internal lead screw drive is used. Thus, the electric fixture 51 drives the jaws 52 to move radially through the internal lead screw mechanism. The electric fixture 51 is a conventional structure and will not be elaborated here.

[0042] Specifically, as Figure 1 and Figure 10As shown, the filtering mechanism 6 includes a liquid collecting tank 61 and a three-way valve 65. A coarse filter screen 62 is fixedly connected to the top of the liquid collecting tank 61, and a fine filter screen 63 is fixedly connected to the inside of the liquid collecting tank 61. A drain pipe 64 is arranged on the side of the fine filter screen 63 away from the coarse filter screen 62. The three-way valve 65 includes two groups of inlets and one group of outlets. One group of inlets of the three-way valve 65 is connected to the drain pipe 64 pipeline, and the other inlet of the three-way valve 65 is connected to the pipeline. A dust cover 66 is arranged at the end of the pipeline. The outlet of the three-way valve 65 is connected to the liquid inlet pipe 484 pipeline. The coarse filter screen 62 is used to further filter large particles of impurities, the fine filter screen 63 is used to filter small particles of impurities, and the dust cover 66 is used to remove debris impurities in the air.

[0043] In actual operation, the inlet connected to the three-way valve 65 and the drain pipe 64 is controlled to be opened, and the inlet connected to the dust cover 66 is controlled to be closed. When the impeller 486 in the rotating shaft 482 rotates, centrifugal force is generated, and the coolant is sucked from the center of the impeller 486 and the liquid inlet pipe 484. Because the center of the impeller forms a low-pressure area due to the liquid being thrown out, the external liquid continuously sucks the coolant inside the liquid collecting tank 61 under the action of atmospheric pressure, and the sucked coolant enters the liquid outlet pipe 485, and cools the drilling hole through the rotating tube 497. At the same time, since the rotation speed of the impeller 486 is synchronized with the rotation speed of the driven drive component 46, the spraying amount of the coolant can be automatically adjusted with the change of the rotation speed during drilling, thereby saving coolant. The inlet connected to the three-way valve 65 and the discharge pipe 64 is controlled to be closed, and the inlet connected to the dust cover 66 is opened. When the impeller 486 in the rotating shaft 482 rotates, centrifugal force is generated, and air is sucked in from the center of the impeller 486 and the liquid inlet pipe 484. Because the center of the impeller forms a low-pressure area due to the liquid being thrown out, the air continuously passes through the three-way valve 65 and enters the rotating shaft 482 under the action of atmospheric pressure. The sucked air then enters the liquid outlet pipe 485, and the drilling hole is cooled by the rotating pipe 497. The rotating pipe 497 performs air cooling and blowing on the drilling hole, thereby reducing the accumulation of debris that affects subsequent drilling or increasing the work intensity of the staff during blowing. The inlet part of the control three-way valve 65 connected to the drain pipe 64 is opened, and the inlet part connected to the dust cover 66 is opened. When the impeller 486 in the rotating shaft 482 rotates, the gas filtered by the dust cover 66 and the coolant filtered inside the collecting tank 61 can be sucked in. When the impeller 486 rotates, the water is sucked by the outer edge of the rotating shaft 482 under the action of centrifugal force to form a thin liquid film or droplets. The air interacts with the liquid film to further tear the droplets to form fine mist particles, thereby achieving an atomization effect. The atomized coolant enters the liquid outlet pipe 485, and the rotating tube 497 cools the drill hole.

[0044] Working principle: Step 1: The staff selects a suitable drilling speed mode and cooling mode according to the properties of the wheel hub to be processed, and turns the two sets of adjustment components 47 to the required drilling speed mode and cooling mode; Specifically, rotation speed mode one during drilling: Reverse the rotation handle 474 to engage the first gear 423 on the active drive assembly 42 with the fourth gear 434 on the first transmission assembly 43 for transmission. When the drive motor 41 starts and drives the spline shaft 421 at a certain rotation speed, the rotation speed of the second shaft 431 can be increased. After the second gear 432 meshes with the main shaft 441 for transmission, the rotation speed of the main shaft 441 is increased, thereby achieving the effect of increasing the drilling speed. Rotation speed mode two during drilling: Forward the rotation handle 474 to engage the sliding gear 422 on the active drive assembly 42 with the third gear 433 on the first transmission assembly 43 for transmission. When the drive motor 41 starts and drives the spline shaft 421 at a certain rotation speed, the rotation speed of the second shaft 431 can be decreased. Even after the second gear 432 meshes with the main shaft 441 for transmission, the rotation speed of the main shaft 441 can be decreased, achieving the effect of decreasing the drilling speed.

[0045] The cooling mode consists of a cooling adjustment mode and a rotation speed mode during drilling. Affected by the cooling adjustment mode and the rotation speed mode during drilling, specifically: Cooling adjustment mode one: The main shaft 441 meshes with the second gear 432 on the second transmission assembly 45 for transmission. Reverse the rotation handle 474 to engage the first gear 423 on the driven drive assembly 46 with the fourth gear 434 on the second transmission assembly 45 for transmission, which can increase the rotation speed of the driven drive assembly 46, thereby achieving the effect of increasing the rotation speed of the first shaft 482 and increasing the cooling capacity. Cooling adjustment mode two: The main shaft 441 meshes with the second gear 432 on the second transmission assembly 45 for transmission. Forward the rotation handle 474 to engage the sliding gear 422 on the driven drive assembly 46 with the third gear 433 on the second transmission assembly 45 for transmission, which can decrease the rotation speed of the driven drive assembly 46, thereby achieving the effect of decreasing the rotation speed of the first shaft 482 and decreasing the cooling capacity. Combining the rotation speed mode during drilling with the cooling mode can result in four cooling modes: Cooling mode one: Combining rotation speed mode one during drilling with cooling adjustment mode one to achieve high drilling rotation speed and high cooling capacity; Cooling mode two: Combining rotation speed mode one during drilling with cooling adjustment mode two to achieve high drilling rotation speed and low cooling capacity; Cooling mode three: Combining rotation speed mode two during drilling with cooling adjustment mode one to achieve low drilling rotation speed and high cooling capacity; Cooling mode four: Combining rotation speed mode two during drilling with cooling adjustment mode two to achieve low drilling rotation speed and low cooling capacity.

[0046] On the basis of four groups of cooling modes, by controlling the opening of the inlet connected to the drain pipe 64 and closing the inlet connected to the dust removal cover 66 of the three-way valve 65, coolant is introduced to perform liquid cooling on the drilling area; by controlling the closing of the inlet connected to the drain pipe 64 and opening the inlet connected to the dust removal cover 66 of the three-way valve 65, air is introduced to perform air cooling and purging on the drilling area; by controlling the partial opening of the inlet connected to the drain pipe 64 and the partial opening of the inlet connected to the dust removal cover 66 of the three-way valve 65, aerosol is introduced to perform spray cooling on the drilling area, thus enriching the drilling modes of the drilling equipment and improving the applicability of the drilling equipment.

[0047] Step 2: The staff or the robotic arm places the hub on the electric fixture 51 at the top of the dual-axis moving base 2, and the electric fixture 51 clamps and fixes the hub. The dual-axis moving base 2 drives the electric fixture 51 to move below the transmission mechanism 4 for drilling.

[0048] Step 3: Adjust the cooling and purging range of the swing assembly 49 to remove the debris generated after drilling.

[0049] In the above manner, different drilling speeds and cooling amounts can be selected according to the drilling requirements of different hubs, and the cooling amount can be adjusted adaptively. On the basis of saving energy consumption, the use of related adjustment equipment can be reduced, and the equipment cost can be lowered; at the same time, the debris generated during drilling can be removed, reducing the work intensity of the staff to clean the debris on the hub.
