Description

Technical Field

[0001] This invention relates to the field of automotive parts processing technology, and in particular to a double-sided positioning drilling machine for processing automotive metal parts. Background Technology

[0002] Drilling is a common process in automobile manufacturing, used to connect, fix, or install automotive parts. Drilling requires the use of a drilling machine, which uses a high-speed rotating drill bit to create holes on the surface of automotive parts.

[0003] An existing double-sided positioning drilling machine for processing automotive metal parts typically requires manual intervention to first fix the position of the unprocessed part before drilling. The part is then removed and transported to the next processing point, and the process is repeated. However, this manual transfer and fixing of parts carries the risk of accidental contact with the drilling machine by the worker's fingers or body, potentially causing injury and increasing workload. Furthermore, the debris generated during drilling is scattered everywhere, and existing debris cleaning devices are fixed in position and difficult to move, easily leading to missed debris and requiring secondary manual cleaning. This reduces drilling efficiency and the flying debris can also injure workers. Summary of the Invention

[0042] The technical solution of the present invention will now be clearly and completely described with reference to specific embodiments. Obviously, the described embodiments are merely some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0043] Specifically, refer to Figure 1-6A double-sided positioning drilling machine for processing automotive metal parts includes a processing table 1, a fixing assembly 2 and a drilling machine 3 mounted on the top of the processing table 1, and a transfer mechanism mounted on the top of the processing table 1, including a first conveyor 6 and a second conveyor 7 mounted on the top of the processing table 1, with a lifting assembly 8 installed between the first conveyor 6 and the second conveyor 7. The transfer mechanism consists of two parts arranged in a circular array. A clamping assembly 9, which can slide along the horizontal direction of the processing table 1, is mounted on the top of the processing table 1. A dust collection mechanism is also included, consisting of components mounted on the top of the processing table 1. The system includes a collection box 10, a reciprocating assembly 11 mounted on top of the collection box 10, a dust suction hood 12 mounted on the outside of the reciprocating assembly 11, a telescopic tube 13 mounted on the outside of the dust suction hood 12, the telescopic tube 13 being connected to the interior of the collection box 10 via a connecting pipe, and a fan 15 with its air inlet connected to the interior of the collection box 10. The system also includes a protective frame 16 mounted on top of the processing table 1, an observation window 17 inside the protective frame 16, a sliding plate 32 inside the processing table 1, and a top of the sliding plate 32 being fixedly connected to the drilling machine 3.

[0044] Two sets of transfer mechanisms are arranged in a 180° circular array. Specifically, the right transfer mechanism is the unloading mechanism, and the left transfer mechanism is the loading mechanism. The first conveyor 6 and the second conveyor 7 on the right convey from back to front, while the first conveyor 6 and the second conveyor 7 on the left convey from front to back. The conveying speeds of the first conveyor 6 and the second conveyor 7 on the left are consistent. Both conveyors operate for five seconds, transporting the automotive parts to a position aligned with the second cylinder 92. Then, they stop operating for five minutes, allowing the clamping assembly to transfer the automotive parts to the interior of the fixed table 21 for processing. The processed parts are then... After being transferred to the right-side transfer mechanism, the left-side first conveyor 6 and second conveyor 7 run for five seconds to transfer the next unprocessed car part to a position in line with the second cylinder 92. This process is repeated, with the conveying speed of the right-side first conveyor 6 and second conveyor 7 remaining consistent. Similarly, when the clamping assembly 9 transfers the processed car part to the top of the two right-side conveyors, the two right-side conveyors run for five seconds to transfer the processed car part to the next position and then stop running for 5 minutes to wait for the next car part to be processed and transferred to the top of the right-side conveyor, thus achieving reciprocating operation.

[0045] The filter plate is designed to block debris from entering the inside of the suction collection box 10, preventing it from entering the inside of the blower 15 and affecting the normal operation of the blower 15. The protective frame 16 is designed to prevent debris from flying everywhere when drilling the component body 19 on the top of the processing table 1, thus protecting the health of the workers.

[0046] In use, the component body 19 is first transported from the outside to the upper side of the right-side lifting member 82 via the first conveyor 6 and the second conveyor 7 on the right side. The first cylinder 81 is activated, driving the right-side lifting member 82 to move upwards, thus raising the component body 19 to the inner side of the two clamping plates 95. The electric push rod 93 drives the two clamping plates 95 to move closer together, thus clamping and fixing the outer side of the component body 19. Subsequently, the electric slide 91 drives the second cylinder 92 to move to the upper side of the fixed platform 21. The push rod 93 is retracted, driving the clamping plate 95 to place the component body 19 inside the fixed platform 21. Then, the clamping plate 95 moves to approach the outside of the component body 19 and clamps the outside of the component body 19. The two drilling machines 3 approach each other to drill holes in the component body 19. The generated debris passes through the dust suction hood 12, the telescopic tube 13, and the connecting tube and enters the collection box 10 for storage. At the same time, the reciprocating component 11 drives the dust suction hood 12 to move and suck up debris from different positions, so that the debris is sucked up more thoroughly and cleanly.

[0047] Component body 19 is a driven roller, model: AJR driven idler wheel (driven roller), diameter: φ60 mm, width (roller surface width): 26mm, two electric push rods 93 drive the clamping plate 95 to a clamping height of 30cm from the processing table, the piston rod of the first cylinder 81 extends downward by 15cm, the height of the part body 19 is fixed at 15cm from the processing table, the tops of the first conveyor 6 and the second conveyor 7 are flush with the top of the processing table 1, the piston rod of the first cylinder 81 drives the lifting member 82 to move upward by 20cm from the top of the processing table 1, the distance of the drilling machine 3 from the processing table 1 is 25cm, when the clamping assembly 9 drives the unprocessed automotive part body 19 to be taken out from the left loading mechanism, the height from the processing table 1 is 21cm, the part body 19 located on the top of the lifting member 82 is taken out and fixed, then the piston rod of the second cylinder 92 retracts inward, so that the height of the clamping assembly 9 and the part body 19 from the processing table 1 is 27cm, thereby effectively avoiding the drilling machine 3, then the slider of the electric slide table 91 drives its The lower component moves to the top of the fixing assembly 2. The second cylinder 92 moves downward by 12cm, and the clamping assembly 9 drives the component body 19 into the fixing assembly 2 for fixing and processing. After drilling is completed, the clamping assembly 9 clamps the component body 19 again, and the second cylinder 92 retracts inward, so that the distance between the clamping assembly 9 and the processing table 1 is 27cm. The slider of the electric slide table 91 drives the second cylinder 92 and the clamping assembly 9 to move to the right to the top of the unloading mechanism. The piston rod of the second cylinder 92 extends downward by 7cm, so that the processed component body 19 is placed on the top of the right lifting member 82. The piston rod of the electric push rod 93 extends outward, driving the clamping plate 95 away from the component body 19, so that the component body 19 is placed on the top of the right lifting member 82. Finally, the piston rod of the first cylinder 81 retracts inward, so that the top of the lifting member 82 is located below the conveyor belt, so that the component body 19 is placed on the top of the two right conveyors and conveyed outward for unloading.

[0048] Extended Example 1: Specifically, refer to... Figure 9 In this embodiment, based on the aforementioned structure, a receiving lifting frame 201 is added inside the fixed platform 21. The receiving lifting frame 201 is driven by a receiving drive unit 202 located below the processing table 1, and its lateral displacement is limited by at least two vertical guide columns. The receiving lifting frame 201 has two support parts arranged at intervals along the workpiece axis. The support parts are located on the axial inner side of the clamping block 23 to avoid interference with the clamping block 23 during the lifting process.

[0049] An elastic contact pad 206 constrained by a limiting guide structure is added to the inner side of the clamping block 23 so that when the two clamping blocks close synchronously through the original gear 25, the difference in the shape of the blank can be compensated within a limited range. The elastic contact pad 206 is only used to distribute the clamping force and does not replace the positioning function of the machining reference weight 203. The necessary rigid limit is set at the end of the contact pad stroke, and the limit position is determined according to the allowable clamping deformation.

[0050] The connection between the clamping plate 95 and the output end of the electric push rod 93 remains unchanged. For workpieces that need to be laterally limited at the conveying height and the processing height, a limiting finger 205 extending vertically is added to the clamping plate 95. The upper part of the limiting finger 205 is provided with a conveying contact area, and the lower part is provided with a processing auxiliary contact area. Both contact areas avoid the movement areas of the drill bit, clamping block 23 and slot 20. The processing auxiliary area holds the workpiece with a force less than the clamping force of the fixed component 2, allowing the workpiece to fall towards the processing reference support 203.

[0051] During loading, the two drilling machines 3 first retreat to the clearance position, the clamping block 23 opens, the locking part 29 rises, and the receiving lifting frame 201 reaches the receiving position. The clamping assembly 9 moves the workpiece from the loading side to above the receiving lifting frame 201. After the receiving contact detection part 205 confirms that the supporting part has received the workpiece, the electric push rod 93 releases the clamping plate 95, and the receiving lifting frame 201 descends, transferring the workpiece to the processing reference support part 203. After confirming that the workpiece is seated, the clamping plate 95 can use the processing auxiliary contact area to provide lateral strength limitation for the workpiece again. Then, the fixing assembly 2 completes the tightening.

[0052] During unloading, the drill bit retracts and confirms the cessation of dangerous cutting actions. The clamping component 29 disengages from the slot 20, the clamping block 23 opens, and the receiving lifting frame 201 raises the workpiece to the conveying contact area. After the clamping plate 95 clamps the workpiece and confirms that it is in place, the receiving lifting frame 201 lowers to make room, and the electric slide table 91 moves the workpiece to the unloading side lifting component 82. After the unloading side lifting component 82 receives the workpiece, the clamping plate 95 releases, the lifting component 82 lowers, and the two ends of the workpiece are respectively placed back onto the first conveyor 6 and the second conveyor 7 on that side.

[0053] Specifically, refer to Figure 4 and Figure 5The fixing assembly 2 includes a fixing platform 21 fixedly installed on the top of the processing table 1. Two symmetrically distributed rotating columns 22 are rotatably connected inside the fixing platform 21. Clamping blocks 23 are fixedly connected to the outer sides of the rotating columns 22. Gears 25 are fixedly connected to the outer sides of both rotating columns 22, and the two gears 25 mesh with each other. A first motor 26, whose output shaft is fixedly connected to the central shaft of one of the gears 25, is fixedly connected to the outer side of the fixing platform 21. The lifting assembly 8 includes a first cylinder 81 fixedly connected to the bottom of the processing table 1. A lifting element 82 is fixedly connected to the output end of the first cylinder 81. Partitions 18 are provided on the outer sides of the conveyor belts of the first conveyor 6 and the second conveyor 7. The clamping assembly 9 includes an electric slide 91 fixedly connected to the inner top wall of the protective frame 16. A second cylinder 92 is fixedly connected to the bottom of the slider of the electric slide 91. An electric push rod 93 is fixedly connected to the outer side of the second cylinder 92. A clamping plate 95 is fixedly connected to the output end of the electric push rod 93.

[0054] In a specific embodiment, the lifting member 82 is disposed on the lower side of the electric slide table 91, and is used to deliver the parts conveyed at the top of the first conveyor 6 and the second conveyor 7 to the inner side of the clamping plate 95. In use, the first cylinder 81 is activated to drive the lifting member 82 to move upward, pushing the part body 19 upward to the inner side of the clamping plate 95. At this time, the electric push rod 93 is activated to drive the clamping plate 95 to move closer to the outer side of the part body 19, clamping the outer side of the part body 19, and transferring the part body 19 to the inside of the fixed table 21 through the cooperation of the electric slide table 91, keeping it stable. At this time, the first motor 26 is activated to drive the gear 25 to rotate in opposite directions, so that the clamping block 23 clamps the outer side of the part body 19, thereby further ensuring the stability of the part body 19 during drilling.

[0055] Extended Example 2: Specifically, refer to... Figure 10 The top of the fixed platform 21 is provided with a groove 209. There are two grooves 209 and they are arranged in a circular array. The two grooves 209 are inclined from the inside to the outside of the fixed platform 21. The end of the groove 209 near the component body 19 is higher than the end away from the component body 19, which facilitates the conveying of debris falling on the top of the fixed platform 21 from the inside of the groove 209 to the outside. The end of each groove 209 is located next to the reciprocating stroke of the corresponding dust suction hood 12.

[0056] The two dust hoods 12 are still moved by the transmission belt 27. The controller determines the available cleaning phase based on the measured position of the two connecting frames. The two dust hoods 12 are not regarded as mechanisms that can be arbitrarily and independently positioned. The position of the interface is designed to match the common movement trajectory of the two hoods, so that there is at least one phase that can connect the two grooves 209. It is also possible to make the two branches connected at the same phase simultaneously under geometric conditions.

[0057] When the extended embodiment 2 detects that a certain support area is not properly seated, the controller keeps the two drilling machines 3 prohibited from feeding, the positioning component 29 retracts, the clamping block 23 retracts to the state where it can be slightly lifted, and the receiving lifting frame 201 lifts the workpiece from the processing reference support component 203 by a short stroke, opening the cleaning gap between the positioning contact surfaces, and the receiving lifting frame 201 bears the weight of the workpiece in this state.

[0058] The fixed table 21 is rectangular in shape, and its top has a V-shaped groove for placing the component body 19. The V-shaped groove design prevents the component body 19 from sliding on the top of the fixed table 21, thereby improving the stability of the component body 19 during processing. The number of teeth of the driving wheel z1=35, the rotation speed n1=1200 rpm, the number of teeth of the driven wheel z2=35, and the transmission ratio is 1. The opening and closing trajectory of the clamping block 23 is to rotate around the rotating column 22 at its bottom towards the end away from the component body 19, thereby placing the component body 19 between the two clamping blocks 23, and then moving the two clamping blocks 23 towards the end of the component body 19, thereby effectively clamping the component body 19 and ensuring the stability of the component body 19 during cutting. The openings of the two dust suction hoods 12 are distributed correspondingly, corresponding to the front and rear sides of the component body 19 respectively, and can slide back and forth on both sides of the component body 19 to the two ends of the component body 19 for dust suction.

[0059] Specifically, refer to Figure 1 and Figure 6 The reciprocating assembly 11 includes a connecting column 111 rotatably connected to the inside of the collection box 10. An incomplete gear 112 is fixedly connected to the top of the connecting column 111. A connecting frame 113 is slidably connected to the top of the collection box 10. A rack meshing with the incomplete gear 112 is provided on the inner wall of the connecting frame 113. The outer side of the connecting frame 113 is fixedly connected to the dust collection hood 12. A telescopic sleeve 35 is fixedly connected to the outer side of the sliding plate 32 and the processing table 1. The telescopic sleeve 35 is located outside the bidirectional threaded rod 31. The first conveyor 6 and the second conveyor 7 are fixedly connected to the inside of the processing table 1. The dust collection hood 12 is fixedly connected to the telescopic tube 13. The connecting tube is fixedly connected to the inside of the collection box 10. The collection box 10 is fixedly connected to the fan 15. The air inlet of the fan 15 is fixedly connected to the inside of the collection box 10. A control panel 36 is fixedly connected to the outer side of the protective frame 16.

[0060] In a specific embodiment, the reciprocating assembly 11 is disposed on the top of the collection box 10, used to enable the dust collection hood 12 to collect debris from different locations. During use, the drilling machine 3 is started to drill holes at both ends of the component, the second motor 28 is started, driving the rear connecting column 111 to rotate, which in turn drives the transmission belt 27. The rotation of the front connecting column 111 then drives the two incomplete gears 112 to rotate, causing the two connecting frames 113 to mesh and reciprocate with the incomplete gears 112. This allows the dust collection hood 12 to reciprocate on the outside of the component body 19. Simultaneously, the fan 15 is started, creating negative pressure within the collection box 10, the telescopic tube 13, and the dust collection hood 12, thus sucking up debris generated on the outside of the component. Figure 8 As shown, the filter plate is located inside the collection box 10 near the blower 15. The end of the filter plate near the blower 15 is the dirty side, and the end of the filter plate away from the blower 15 is the clean side. The filter plate has a filter hole size of 30μm, which can filter both coarse and long debris and fine debris at the same time. The air outlet of the blower 15 and the collection box 10 are sealed to prevent air leakage at the connection point, which would cause debris to leak from the connection between the collection box 10 and the air outlet of the blower 15.

[0061] Specifically, refer to Figure 3 and Figure 5 The output end of the second cylinder 92 is fixedly connected to a positioning component 29, and the interior of the fixed table 21 houses the component body 19. A third motor 30 is fixedly connected to the bottom of the machining table 1, and the output shaft of the third motor 30 is fixedly connected to a bidirectional threaded rod 31. The outer side of the bidirectional threaded rod 31 is threadedly connected to a sliding plate 32. There are two sliding plates 32 and two drilling machines 3, symmetrically distributed. A telescopic sleeve 35 is fixedly connected to the outer side of the sliding plate 32 and the machining table 1. The telescopic sleeve 35 is located outside the bidirectional threaded rod 31. The electric push rod 93 is fixed to the outside of the cylinder body, and the piston of the second cylinder 92 drives the positioning component 29 to move downwards.

[0062] In a specific implementation, the slot 20 is located on the lower side of the positioning member 29 to ensure the stability of the component body 19 during drilling. In use, the slider of the electric slide table 91, the second cylinder 92, and the positioning member 29 are controlled by the control panel 36 to move to the top of the slot 20 of the component body 19, so that the positioning member 29 and the slot 20 are aligned. The second cylinder 92 is activated to drive the positioning member 29 to move downward into the slot 20, thereby keeping the component body 19 stable. Then, the third motor 30 is activated to drive the bidirectional threaded rod 31 to rotate, which drives the sliding plate 32 to slide towards each other. The drilling machine 3 moves towards the end close to the component body 19, so that the drill bit of the drilling machine 3 drills holes at both ends of the component body 19 at the same time. Due to the design of the telescopic sleeve 35 on the outer side of the bidirectional threaded rod 31, it prevents the debris generated when drilling the inside of the component body 19 from entering the interior of the bidirectional threaded rod 31 and affecting the normal operation of the bidirectional threaded rod 31.
