[0037] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] See also Figure 1-10The present invention provides a technical solution: a drilling equipment for processing automobile wheel hubs, comprising a base 1, a biaxial movable base 2 and a vertical movable mechanism 3 arranged on the top of the base 1, a transmission mechanism 4 arranged on the vertical movable mechanism 3, a clamping mechanism 5 arranged on the top of the biaxial movable base 2, and a filtering mechanism 6 arranged below the base 1, the vertical movable mechanism 3 is arranged at the edge of the top of the base 1, the biaxial movable base 2 is arranged on the side of the vertical movable mechanism 3 away from the edge, the biaxial movable base 2 is used to drive the wheel hub clamped and fixed by the clamping mechanism 5 to approach or move away from the vertical movable 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 movable mechanism 3, the vertical movable mechanism 3 is used to drive the transmission mechanism 4 to approach or move away from the wheel hub clamped by the clamping mechanism 5 in the vertical direction and to drill and cool the wheel hub, and the filtering mechanism 6 is used to collect and filter the coolant.

[0039] It should be noted that the dual-axis movable seat 2 can adopt a transmission structure in which a motor drives a screw rod, or can also adopt a structure in which a cylinder or a hydraulic cylinder is extended and driven to move.

[0040] Specifically, such as Figure 1 As shown, a liquid collecting tray 11 is fixedly connected to the top of the base 1, and a filter hole 12 is provided 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 for preliminary filtering to remove large-sized debris in the coolant.

[0041] Specifically, such as Figure 1 and Figure 2 As shown, the vertical movement mechanism 3 includes a column 31 fixed to one side of the top of the base 1, a driving part 35 provided on the top of the column 31, and a transmission housing 36 provided on the side of the column 31 away from the side of the base 1. The column 31 is a hollow structure. A counterweight block 32 is slidably connected to the inside of the column 31. Two sets of chains 33 are fixedly connected to the top of the counterweight block 32. The other ends of the chains 33 are fixedly connected to the top of the transmission housing 36. Two sets of sprockets 34 are connected to the bearings on the top of the column 31. Each set of sprockets 34 is provided with two, and the chains 33 are meshed with the sprockets 34.

[0042] The transmission housing 36 is slidably connected to the column 31 , and the output end of the driving portion 35 is transmission-connected to the transmission housing 36 .

[0043] It should be noted that the driving part 35 is preferably a transmission structure in which a motor drives a screw. In this case, the output end of the driving part 35 is threadedly connected to the transmission housing 36 .

[0044] In actual operation, the driving unit 35 is started, driving the transmission housing 36 to move up and down along the vertical direction of the column 31. Under the gravity of the counterweight 32 and the meshing transmission of the chain 33 and the sprocket 34, when the driving unit 35 drives the transmission housing 36 to rise, the counterweight 32 descends; when the driving unit 35 drives the transmission housing 36 to descend, the counterweight 32 rises, thereby ensuring that the driving unit 35 can drive the transmission housing 36 to rise and fall with good stability, which is conducive to improving the subsequent drilling quality.

[0045] Specifically, such as Figure 3-Figure 8 As shown, the transmission mechanism 4 includes a drive motor 41, an active drive component 42, a transmission component 1 43, a drilling component 44, a transmission component 2 45, a driven drive component 46, two sets of adjustment components 47, a cooling component 48 and a swing component 49. The drive motor 41 is fixed to the top of the transmission housing 36. The active drive component 42, the transmission component 1 43, the drilling component 44, the transmission component 2 45 and the driven drive component 46 are sequentially connected in a direction from close to to away from the vertical moving mechanism 3. The adjustment components 47 are arranged on both sides of the transmission housing 36. The positions of the two sets of adjustment components 47 correspond to the positions of the active drive component 42 and the driven drive component 46 respectively. The adjustment component 47 is used to shift the gear positions on the active drive component 42 and the driven drive component 46. The cooling component 48 is transmission-connected to the driven drive component 46. The swing component 49 is arranged at the bottom of the transmission housing 36. The drilling component 44 is used for drilling. The driven drive component 46 is used to drive the cooling component 48 to rotate. The cooling component 48 is used to extract coolant. The swing component 49 is used to adjust the alignment position during cooling.

[0046] Further, such as Figure 4 and Figure 5 As shown, the active drive assembly 42 includes a spline shaft 421 fixedly connected to the output end of the drive motor 41, a sliding gear 422 spline-connected to the spline shaft 421, and a gear 1 423 key-connected to the sliding gear 422. The spline shaft 421 is connected to the bearing of the transmission housing 36, and the gear 1 423 is arranged on the periphery of the sliding gear 422. A stop nut is provided on the sliding gear 422, and the stop nut is provided at the bottom of the gear 1 423. The stop nut is used to limit the axial position of the gear 1 423 on the sliding gear 422.

[0047] like Figure 4 and Figure 5 As shown, the transmission assembly 43 includes a rotating shaft 2 431 connected to the bearing of the transmission housing 36 and a gear 2 432, a gear 3 433, and a gear 4 434 fixed on the rotating shaft 2 431 from top to bottom. The gear 3 433 is engaged with the sliding gear 422, and the gear 4 434 is engaged with the gear 1 423.

[0048] It should be noted that for the sliding gear 422 and gear 1 423 of the active drive component 42 and gear 3 433 and gear 4 434 of the transmission component 1 43, gear 3 433 will not be engaged with the sliding gear 422 and gear 4 434 will not be engaged with gear 1 423 at the same time.

[0049] like Figure 4 and Figure 5 As shown, the drilling assembly 44 includes a main shaft 441 connected to the bearing of the transmission housing 36 and a gear five 442 fixed on the main shaft 441. The gear five 442 is engaged with the gear three 433 for transmission. A main shaft sleeve 443 is provided on the periphery of the main shaft 441. The main shaft sleeve 443 is fixedly connected to the transmission housing 36. A chip breaker 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 the coolant from penetrating into the transmission mechanism 4.

[0050] like Figure 4-Figure 6 The structure and arrangement of the transmission component 2 45 are the same as those of the transmission component 1 43 , and the structure and arrangement of the driven drive component 46 are the same as those of the active drive component 42 , but a bevel gear 1 461 is fixedly connected to the bottom of the driven drive component 46 .

[0051] like Figure 4-Figure 6 As shown, the adjustment assembly 47 includes a paddle 471 and a connecting rod 472. The connecting rod 472 is C-shaped and is arranged on the radial periphery of gear 1 423 and on both axial sides of gear 1 423. The paddle 471 maintains a gap with the tooth top circle of gear 423. One end of the connecting rod 472 is connected to the paddle 471 with a bearing, and the other end of the connecting rod 472 is connected to the fork shaft 473 with a bearing. The fork shaft 473 is fixedly connected to the rotating handle 474. The rotating handle 474 is arranged on the outside of the transmission housing 36, and the rotating handle 474 is connected to the transmission housing 36 with a bearing.

[0052] It should be noted that the diameter of gear one 423 is larger than the diameter of the sliding gear 422, and the diameter of gear three 433 is larger than the diameter of gear four 434. When the sliding gear 422 and gear three 433 are engaged, the speed is increased, and when gear one 423 and gear four 434 are engaged, the speed is decreased.

[0053] In actual operation, the counterclockwise rotation of the rotating handle 474 drives the synchronous shift fork shaft 473 to rotate counterclockwise. At this time, the rotating handle 474 is toggled in the reverse direction, 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 paddle 471 drives the gear 1 423 on the driven drive assembly 46 to slide down along the axial direction of the spline shaft 421, so that the gear 1 423 on the driven drive assembly 46 engages with the gear 4 434 on the transmission assembly 2 45, thereby changing the gears driven by the transmission assembly 2 45 and the driven drive assembly 46.

[0054] Then, the rotating handle 474 is rotated clockwise. At this time, the rotating handle 474 is turned in the positive direction, which can drive the gear 1 423 on the driven drive component 46 to slide along the axial direction of the spline shaft 421, and the gear 1 423 on the driven drive component 46 can be meshed with the gear 4 434 on the transmission component 2 45 for transmission, and the transmission is converted into the transmission of the sliding gear 422 on the driven drive component 46 and the gear 3 433 on the driven drive component 46, thereby realizing variable speed transmission. Similarly, by turning the paddle 471 on the adjustment component 47 close to the side of the active drive component 42, the gears transmitted on the active drive component 42 and the transmission component 1 43 can also be adjusted, so that the gear 1 423 on the active drive component 42 is meshed with the gear 4 434 on the transmission component 1 43 or the sliding gear 422 on the active drive component 42 is meshed with the gear 3 433 on the transmission component 1 43, thereby facilitating the adjustment of the rotation speed and cooling amount during drilling.

[0055] It should be noted that, in actual use, the rotating handle 474 can be changed to be driven by a motor, which can further achieve automatic speed change.

[0056] like Figure 7 As shown, the cooling assembly 48 includes a bevel gear 2 481 meshing with the bevel gear 1 461 and a shell 483 fixed inside the transmission shell 36. The bevel gear 2 481 is fixedly connected to the rotating shaft 1 482. The rotating shaft 1 482 is connected to the bearing of the shell 483. The end of the rotating shaft 1 482 away from the bevel gear 1 461 is fixedly connected to the impeller 486. The impeller 486 is located inside the shell 483. The axial side of the shell 483 is connected to the liquid inlet pipe 484, and the liquid inlet pipe 484 corresponds to the center of the impeller 486. The radial side of the shell 483 is connected to the liquid outlet pipe 485, and the liquid outlet pipe 485 is connected to the pipeline of the filtering mechanism 6.

[0057] In actual operation, when the driven drive assembly 46 rotates, the meshing transmission of bevel gear 1 461 and bevel gear 2 481 can drive the rotating shaft 1 482 to rotate, thereby driving the impeller 486 to rotate. The centrifugal force generated by the rotation of the impeller 486 is used to suck liquid or air 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.

[0058] like Figure 7 and Figure 8As shown, the swing assembly 49 includes a connector 491 connected to the liquid outlet pipe 485, a rotating tube 497 rotatably connected to the connector 491, the end of the rotating tube 497 is aligned with the chip breaker drill bit, and the bottom of the transmission housing 36 is fixedly connected to a slide rail 492 and a cylinder 493, the cylinder 493 is arranged on one side of the slide rail 492, the output end of the cylinder 493 passes 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 arranged inside the slide rail 492 and is slidably connected to the slide rail 492, the rack 494 is meshed with gear six 495, the gear six 495 is fixedly connected to a connecting shaft, the connecting shaft is connected to the bearing of the transmission housing 36, a sector gear 496 is fixedly connected to the connecting shaft, the sector gear 496 is meshed with gear seven 498, and the gear seven 498 is fixed on the rotating tube 497.

[0059] During actual use, the cylinder 493 extends, driving the rack 494 to slide in the slide rail 492 toward the side away from the cylinder 493. Through the meshing transmission of the rack 494 and the gear six 495, the gear six 495 can be driven to rotate counterclockwise. Since the gear six 495 and the fan gear 496 are fixedly connected to the connecting shaft, the fan gear 496 can be synchronously driven to rotate counterclockwise. Since the fan gear 496 is meshed with the gear seven 498, the fan gear 496 can drive the gear seven 498 to rotate clockwise, and then drive the rotating tube 497 to rotate clockwise. Conversely, the cylinder 493 contracts, which can drive the rotating tube 497 to rotate counterclockwise, thereby achieving the effect of adjusting the flushing range of the coolant in the rotating tube 497.

[0060] Specifically, such as Figure 9 As shown, the clamping mechanism 5 includes an electric clamp 51 fixed to the top of the dual-axis movable seat 2, and a plurality of clamping jaws 52 are provided on the electric clamp 51. A plurality of springs 53 are fixedly connected to the top of the clamping jaws 52, and a sliding sleeve 54 is slidably connected to the clamping jaws 52. The other end of the spring 53 is fixedly connected to the inside of the sliding sleeve 54.

[0061] In actual operation, the wheel hub is placed on the electric clamp 51, and the spring 53 contracts under the action of the gravity of the wheel hub to ensure that the top of the sliding sleeve 54 can correspond to the center bottom support. Then the electric clamp 51 is actuated to move the jaws 52 away from the center of the electric clamp 51, so that the outer diameter of the jaws 52 can fit the inner diameter of the wheel hub, supporting the wheel hub to be drilled. It is also suitable for wheels of different sizes, which improves the applicability of the drilling device.

[0062] It should be noted that the electric clamp 51 is preferably driven by a built-in screw, so that the electric clamp 51 drives the clamping jaw 52 to move radially through the built-in screw mechanism. The electric clamp 51 is an existing structure and will not be described in detail here.

[0063] Specifically, such 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 provided 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 removal cover 66 is provided 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 removal cover 66 is used to remove debris and impurities in the air.

[0064] In actual operation, the inlet connected to the three-way valve 65 and the drain pipe 64 is controlled to be open, 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 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 external liquid continuously sucks the coolant inside the collecting tank 61 under the action of atmospheric pressure, and the sucked coolant then enters the liquid outlet pipe 485 and cools the drilled 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 as the rotation speed changes during drilling, thereby saving coolant.

[0065] 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 1 482 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 1 482 under the action of atmospheric pressure. The sucked air then enters the liquid outlet pipe 485 and cools the drilled hole through the rotating pipe 497. The rotating pipe 497 performs air cooling and purge on the drilled hole, thereby reducing the accumulation of debris that affects subsequent drilling or increasing the workload of the workers during purge.

[0066] 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 into 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, achieving an atomization effect. The atomized coolant then enters the liquid outlet pipe 485, and the rotating tube 497 cools the drill hole.

[0067] Working principle:

[0068] Step 1: The staff selects the appropriate drilling speed mode and cooling mode according to the properties of the wheel hub to be processed, and dials the two sets of adjustment components 47 to the required drilling speed mode and cooling mode;

[0069] Specifically, in the first speed mode during drilling, the rotary handle 474 is turned in the opposite direction, so that the gear 1 423 on the active drive assembly 42 engages with the gear 4 434 on the transmission assembly 1 43. When the drive motor 41 starts and drives the spline shaft 421 to a certain speed, the speed of the second rotating shaft 431 can be increased. Then, after the gear 2 432 engages with the main shaft 441, the speed of the main shaft 441 is increased, thereby achieving the effect of increasing the drilling speed.

[0070] Speed mode 2 during drilling: Turn the rotating handle 474 in the forward direction, so that the sliding gear 422 on the active drive component 42 engages with the gear three 433 on the transmission component 1 43. When the drive motor 41 starts and drives the spline shaft 421 at a certain speed, the speed of the rotating shaft 2 431 can be reduced. Even after the gear 2 432 engages with the main shaft 441, the speed of the main shaft 441 can be reduced, thereby achieving the effect of reducing the drilling speed.

[0071] The cooling mode consists of the cooling adjustment mode and the drilling speed mode. It is affected by the cooling adjustment mode and the drilling speed mode, specifically:

[0072] Cooling adjustment mode 1: The main shaft 441 is meshed with the second gear 432 on the second transmission assembly 45. The rotating handle 474 is turned in the opposite direction, so that the first gear 423 on the driven drive assembly 46 is meshed with the fourth gear 434 on the second transmission assembly 45. This can increase the speed of the driven drive assembly 46, thereby increasing the speed of the rotating shaft 1 482 and achieving the effect of increasing the cooling capacity.

[0073] Cooling adjustment mode 2: The main shaft 441 is meshed with the second gear 432 on the second transmission assembly 45. Turning the rotating handle 474 in the positive direction causes the sliding gear 422 on the driven drive assembly 46 to mesh with the third gear 433 on the second transmission assembly 45. This can reduce the speed of the driven drive assembly 46, thereby reducing the speed of the rotating shaft 1 482 and achieving the effect of reducing the cooling capacity.

[0074] Combining the speed mode during drilling with the cooling mode, four cooling modes can be obtained:

[0075] Cooling mode 1: The drilling speed mode 1 is combined with the cooling adjustment mode 1 to achieve high drilling speed and high cooling capacity;

[0076] Cooling mode 2: The drilling speed mode 1 is combined with the cooling adjustment mode 2 to achieve high drilling speed and low cooling amount;

[0077] Cooling mode 3: The drilling speed mode 2 is combined with the cooling adjustment mode 1 to achieve low drilling speed and high cooling capacity;

[0078] Cooling mode 4: The drilling speed mode 2 is combined with the cooling adjustment mode 2 to achieve low drilling speed and low cooling amount.

[0079] On the basis of the four groups of cooling modes, the inlet connected to the three-way valve 65 and the drain pipe 64 is controlled to be open, and the inlet connected to the dust cover 66 is closed, and coolant is introduced to perform liquid cooling on the drill hole; the inlet connected to the three-way valve 65 and the drain pipe 64 is controlled to be closed, and the inlet connected to the dust cover 66 is controlled to be opened, and air is introduced to perform air cooling and purging on the drill hole; the inlet part connected to the three-way valve 65 and the drain pipe 64 is controlled to be opened, and the inlet part connected to the dust cover 66 is controlled to be opened, and aerosol is introduced to perform spray cooling on the drill hole, thereby enriching the drilling modes of the drilling equipment and improving the applicability of the drilling equipment.

[0080] Step 2: The staff or the robotic arm places the wheel hub on the electric clamp 51 on the top of the dual-axis movable seat 2. The electric clamp 51 clamps and fixes the wheel hub. The dual-axis movable seat 2 drives the electric clamp 51 to move to the bottom of the transmission mechanism 4 for drilling.

[0081] Step 3: Adjust the cooling and blowing range of the swing assembly 49 to remove the debris generated after the drilling is completed.

[0082] Through the above method, different drilling speeds and cooling amounts can be selected according to the drilling needs of different wheel hubs, and the cooling amount can be adaptively adjusted. On the basis of saving energy consumption, the use of related adjustment equipment can be reduced, thereby reducing equipment costs. At the same time, the debris generated during drilling can be removed, reducing the workload of workers in cleaning the debris on the wheel hub.
