Description

Technical Field

[0001] The invention relates to the technical field of wheel hub drilling, and in particular to an intelligent drilling device for wheel hub production. Background Art

[0002] The wheel hub is one of the core components of the wheels of vehicles such as cars and bicycles. It connects the tire and the axle and plays the role of supporting and fixing the tire. The wheel hub is usually made of metal, such as steel or aluminum alloy.

[0003] After the wheel hub surface shape processing is completed, it is usually necessary to drill holes in the outer and inner rings of the wheel hub. The holes that need to be drilled in the inner ring are mounting holes, which are used to fix the wheel hub to the axle of the car. The number and distribution of mounting holes depend on the model and design of the car. Common ones are 4 holes, 5 holes, etc. The holes are distributed in a circle around the center of the wheel hub to form the so-called pitch circle diameter, and the holes that need to be drilled in the outer ring are the inner sleeve holes. The inside of the inner sleeve hole is used to install the thread sleeve, and the outside of the thread sleeve is used to install the anti-slip ring, so that the anti-slip ring is installed on both sides of the wheel hub to position the tire.

[0004] The existing wheel hub outer ring and inner ring drilling requires workers to use two drilling devices to drill holes separately. The two machines drill holes on the outer ring and inner ring of the wheel hub respectively, which not only increases the operating steps and workload of the workers, but also is prone to human operation errors, resulting in low drilling efficiency and poor drilling accuracy of the wheel hub outer ring and inner ring. After the drilling is completed, the two devices need to be debugged and maintained separately, which increases the complexity and cost of equipment management.

[0028] Specifically, the sliding up and down of the sliding end of the second electric slide rail 52 is used to control the multi-turn drilling mechanism 6 to approach the wheel hub when drilling is required or to move away from the wheel hub when drilling is completed.

[0029] See also Figure 6 The multi-turn drilling mechanism 6 includes a drill disc 64 fixedly connected to the sliding end of the second electric slide rail 52, a guide slide cylinder 62 is fixedly connected to the upper side of the drill disc 64, a first hydraulic cylinder 61 is fixedly connected to the upper side of the guide slide cylinder 62, an output end of the first hydraulic cylinder 61 passes through the guide slide cylinder 62 and is fixedly connected to a second motor 63, a sleeve is fixedly connected to the outer side of the second motor 63 and the sleeve is slidably connected to the inner wall of the guide slide cylinder 62, a transmission shaft is fixedly connected to the output end of the second motor 63, one end of the transmission shaft passes through the drill disc 64 and is fixedly connected to a square key.

[0030] Specifically, the extension and retraction of the output end of the first hydraulic cylinder 61 is used to drive the second motor 63 to move up and down, thereby driving the square key to move up and down inside the drill plate 64, and the rotation of the output end of the second motor 63 is used to drive the square key to rotate.

[0031] An outer ring drilling assembly 66 is provided inside the drilling disc 64 , an inner ring drilling assembly 65 is provided inside the outer ring drilling assembly 66 , and a cooling assembly 67 is provided outside the outer ring drilling assembly 66 .

[0032] See also Figure 7 A water trough 641 is provided on the upper part of the interior of the drill disc 64, and water channels 643 are evenly provided on the lower side of the water trough 641. An avoidance groove 642 is provided on one side of the water channel 643. A sliding platform 645 is provided on the lower side of the avoidance groove 642, and the sliding platform 645 is slidably connected to the drill disc 64. A fixing cylinder 644 is fixedly connected to the lower side of the drill disc 64. A plurality of heat dissipation holes 646 are provided on the bottom of the drill disc 64, and the heat dissipation holes 646 are connected to the avoidance groove 642.

[0033] Specifically, the interior of the water tank 641 is used to pass cooling water, and the cooling water then flows from the interior of the water tank 641 into the interior of each water channel 643 in sequence.

[0034] See also Fig.10 The outer ring drilling assembly 66 includes a first rotating ring 666 rotatably connected to the inside of the avoidance groove 642, a first gear 661 is fixedly connected to the upper side of the first rotating ring 666, a first square groove 662 is provided in the center of the first gear 661, a plurality of first clamping cylinders 664 are evenly rotatably connected to the inside of the avoidance groove 642, a second gear 663 is fixedly connected to the upper side of each first clamping cylinder 664 and the second gear 663 is meshed with the first gear 661, an outer ring hole drill bit 665 is fixedly connected to the inside of each first clamping cylinder 664, and one end of the outer ring hole drill bit 665 passes through the drill disc 64.

[0035] Specifically, in order to prevent the inner ring hole drill bit 656 from hitting the inner ring of the wheel hub when the outer ring hole drill bit 665 is gun drilling the outer ring of the wheel hub, the bottom end of the outer ring hole drill bit 665 is lower than the bottom end of the inner ring hole drill bit 656 in the initial state. When it is necessary to drill a hole in the outer ring of the wheel hub, the output end of the second motor 63 rotates to drive the square key to rotate. Since the square key is connected with the first square groove 662 of the first gear 661, the first gear 661 is indirectly driven to rotate rapidly, thereby driving the several second gears 663 outside the first gear 661 to rotate, and the second gear 663 drives the first clamping cylinder 664 to rotate, thereby driving each outer ring hole drill bit 665 to rotate, and the sliding end of the second electric slide rail 52 moves downward to drive the outer ring hole drill bit 665 to drill holes in the outer ring of the wheel hub. When all the holes in the outer ring of the wheel hub are gun drilled, the sliding end of the second electric slide rail 52 moves upward to drive the outer ring hole drill bit 665 to return.

[0036] See also Fig.11 The inner ring drilling assembly 65 includes a second rotating ring 653 rotatably connected to the inside of the sliding table 645, a third gear 652 is fixedly connected to the upper side of the second rotating ring 653, a second square groove 651 is provided at the center of the third gear 652, five second clamping cylinders 655 are provided on the outer side of the second rotating ring 653, and the second clamping cylinders 655 are rotatably connected to the sliding table 645, a fourth gear 654 is fixedly connected to the upper side of each second clamping cylinder 655, and the fourth gear 654 is meshed with the third gear 652, an inner ring hole drill 656 is fixedly connected to the inside of the second clamping cylinder 655, and one end of the inner ring hole drill 656 passes through the fixed cylinder 644, a plurality of first springs 657 are fixedly connected to the lower side of the sliding table 645, and the other end of the first spring 657 is fixedly connected to the inner wall of the fixed cylinder 644.

[0037] Specifically, when the outer ring of the wheel hub is drilled, the output end of the first hydraulic cylinder 61 drives the square key to move downward, and the output end of the second motor 63 drives the square key to rotate at a low speed until the square key is inserted into the second square groove 651 and connected therewith. The output end of the second motor 63 drives the square key to rotate rapidly, and indirectly drives the third gear 652 to rotate, thereby driving the second clamping cylinder 655 to rotate, and then drives each inner ring hole drill bit 656 to rotate rapidly. The output end of the first hydraulic cylinder 61 continues to extend, and the square key presses the sliding table 645 downward, driving the sliding table 645 to move downward. At this time, the first spring 657 is compressed until the bottom end of the outer ring hole drill bit 665 is high. At the bottom end of the inner ring hole drill 656, the output end of the first hydraulic cylinder 61 stops extending, and the sliding end of the second electric slide rail 52 moves downward to drive the inner ring hole drill 656 to drill the inner ring of the wheel hub. When all the holes in the inner ring of the wheel hub are gun-drilled, the sliding end of the second electric slide rail 52 moves upward to drive the drill disc 64 to return, and the output end of the first hydraulic cylinder 61 retracts to drive the square key to move upward. The output end of the second motor 63 rotates at a low speed to make the square key fit into the first square groove 662 again, and the sliding table 645 is driven upward by the elastic force of the first spring 657, indirectly driving the inner ring hole drill 656 to return.

[0038] The square key is driven up and down by the extension and retraction of the output end of the first hydraulic cylinder 61, so that the square key is inserted into the first square groove 662 and the second square groove 651 in turn, and the second motor 63 indirectly drives the first gear 661 and the third gear 652 to rotate in turn, thereby driving the outer ring hole drill bit 665 and the inner ring hole drill bit 656 to rotate, and automatically gun drills the holes of the outer ring and the inner ring of the wheel hub in turn. When the wheel hub is gun drilling the holes of the inner ring and the outer ring, no personnel control is required and gun drilling is performed on the same equipment, thereby achieving a high efficiency in drilling the outer ring and the inner ring of the wheel hub.

[0039] In the second embodiment, due to the excessive number of holes to be gun-drilled in the outer ring, the first gear 661 is meshed with too many second gears 663. Each second gear 663 exerts force on the first gear 661 when meshing. The more second gears 663 there are, the greater the total pressure on the tooth surface of the first gear 661 is, thereby accelerating the wear of the tooth surface of the first gear 661, and causing the first gear 661 to generate excessive debris that is adsorbed on the meshing surface of the second gear 663. The generated wear debris will contact the surface of the first gear 661 again, forming a vicious circle, causing the first gear 661 to wear faster and faster, shortening the service life of the first gear 661, and when too many gears are meshed and rotated, a large amount of heat will be generated around the first gear 661. The first gear 661 and the second gear 663 will undergo thermal expansion at high temperature, which will increase the contact stress on the tooth surface, thereby accelerating the wear of the tooth surface. Therefore, the following structure is designed to solve the above technical problems.

[0040] See also Figure 4 A water tank 44 is provided on the lower side of the first electric slide rail 2 and the water tank 44 is fixedly connected to the workbench 1, a second water pump 45 is fixedly connected to one side of the water tank 44, the input end of the second water pump 45 is connected to the output end of the water tank 44 by a pipeline, a first support frame 41 is fixedly connected to the upper side of the workbench 1, a water bucket 42 is fixedly connected to the upper side of the first support frame 41, the input end of the water bucket 42 is connected to the output end of the second water pump 45 by a pipeline, a first water pump 43 is fixedly connected to the upper side of the water bucket 42, the input end of the first water pump 43 is connected to the output end of the water bucket 42 by a pipeline, and the output end of the first water pump 43 is connected to the water tank 641 by a pipeline.

[0041] Specifically, the interior of the water tank 44 is used to store cooling water jetted during gun drilling, the second water pump 45 is used to pump the cooling water in the water tank 44 into the water bucket 42 for storage, the first water pump 43 is used to pump the cooling water in the water bucket 42 into the water tank 641, and the water tank 641 is used to cool the drill disc 64, thereby reducing the temperature inside the avoidance groove 642, and further reducing the heat generated by the meshing rotation between the gears.

[0042] See also Figure 8 and Fig. 9 The cooling assembly 67 includes a guide platform 671 fixedly connected to the top of each water channel 643, a rotating shaft 673 is provided on the lower side of the guide platform 671 and the rotating shaft 673 is rotatably connected to the drill disc 64, four semi-circular arc disks 674 are evenly fixedly connected to the outer side of the rotating shaft 673, a fan 672 is fixedly connected to one end of the rotating shaft 673, a plurality of second nozzles 676 are provided on the lower side of the drill disc 64 and the second nozzles 676 are fixedly connected to the water channel 643, and five water channels 643 are each provided with a first nozzle 675.

[0043] Specifically, when the outer ring hole drill bit 665 is drilling a hole in the outer ring of the wheel hub, the first water pump 43 is started at high power to pump the cooling water inside the water bucket 42 into the water tank 641, and the cooling water inside the water tank 641 is diverted to the inside of each water channel 643 in turn. The cooling water is diverted by the guide platform 671. Due to the excessive water pressure, the high-pressure cooling water impacts on the top of each semicircular arc disk 674 in turn, thereby driving the rotating shaft 673 to rotate rapidly, and then driving each fan 672 to rotate rapidly, cooling each second gear 663 in turn, and dissipating the heat inside the avoidance groove 642 through the heat dissipation hole 646.

[0044] When the second gear 663 rotates rapidly, centrifugal force is generated to throw out most of the iron filings adsorbed on the surface. However, there is still some iron filings adsorbed on the surface of the second gear 663. The fan 672 rotates rapidly, and the wind direction of the fan 672 is consistent with the movement direction of the second gear 663. The two cooperate with each other, so that the other part of the iron filings adsorbed on the surface of the second gear 663 can be more easily blown away by the fan 672.

[0045] Finally, the valves of the second nozzle 676 and the first nozzle 675 are opened, and the cooling water passing through the semicircular arc disk 674 is sprayed out from the spray ends of the second nozzle 676 and the first nozzle 675, and sprayed on the drilling ends of the outer circle hole drill bit 665 in turn to cool down the outer circle hole drill bit 665.

[0046] See also Fig.12 , five guide grooves 6755 are evenly arranged inside the fixed cylinder 644, and a connecting plate 6754 is slidably connected inside the guide groove 6755. One end of the connecting plate 6754 is fixedly connected to the outer wall of the sliding platform 645 and the other end is fixedly connected to a pressure ring 6753. A limiting groove is arranged on the outer side of the first nozzle 675, and a pressure ring 6753 is slidably connected to the outer side of the limiting groove. A slide plate 6751 is fixedly connected to the upper side of the first nozzle 675 and the slide plate 6751 is slidably connected to the drill disc 64. A plurality of second springs 6752 are fixedly connected to the lower side of the slide plate 6751 and the other end of the second spring 6752 is fixedly connected to the drill disc 64.

[0047] Specifically, the second spring 6752 is used to support the first nozzle 675 to prevent the first nozzle 675 from falling off downward. When the inner ring hole drill bit 656 drills the inner ring of the hub, the sliding table 645 moves downward, driving the inner ring hole drill bit 656 to move downward, and indirectly driving the connecting plate 6754 to move downward along the guide groove 6755, thereby driving the pressure ring 6753 to move downward. When the pressure ring 6753 slides to the bottom of the guide groove 6755, the first nozzle 675 is aligned with the drilling end of the inner ring hole drill bit 656. In order to prevent the cold water ejected by the first nozzle 675 from The cooling water is blocked by the drilling end of the outer circle hole drill bit 665, and the pressure ring 6753 continues to move downward to drive the first nozzle 675 to move downward, and the inner circle hole drill bit 656 moves downward synchronously. At this time, the second spring 6752 is compressed until the route of the cooling water sprayed from the injection end of the first nozzle 675 is no longer blocked by the outer circle hole drill bit 665, and the first nozzle 675 and the inner circle hole drill bit 656 stop moving downward. At this time, the valve of the first nozzle 675 is opened, and the valve of the second nozzle 676 is closed, and cooling water is sprayed from the injection end of the first nozzle 675, thereby cooling the inner circle hole drill bit 656 that is drilling.

[0048] The cooling water is pumped into the water tank 641 by the first water pump 43, and the inside of the avoidance tank 642 is indirectly cooled. When the high-pressure cooling water passes through the water channel 643, the fan 672 is driven to rotate by the impact force of the water flow. When the fan 672 rotates, it can not only cool each second gear 663, but also assist in blowing away the iron filings on the surface of the second gear 663 whose movement direction is consistent with the rotation direction of the fan 672. The cooling water passing through the semicircular arc disk 674 is sprayed on the outer ring through the second nozzle 676 and the first nozzle 675. The drilling end of the hole drill bit 665 cools down the outer circle hole drill bit 665, and the spraying area of ​​the first nozzle 675 can be adjusted while the inner circle hole drill bit 656 moves downward, so that the spraying route of the first nozzle 675 avoids the drilling end of the outer circle hole drill bit 665, and directly sprays and cools the drilling end of the inner circle hole drill bit 656, and then the spraying area of ​​the first nozzle 675 switches back and forth between the two areas of the drilling end of the inner circle hole drill bit 656 and the drilling end of the outer circle hole drill bit 665, thereby achieving high cooling efficiency and debris cleaning effects.
