Description

Technical Field

[0001] The present invention relates to the technical field of drilling equipment, and particularly to a drilling device for automobile parts processing. Background Art

[0002] In the field of automobile parts processing, the drilling operation of plates is a very common and crucial process. Many components of automobiles, such as body frames, doors, engine hoods, etc., all involve plates, and the drilling accuracy on these plates is directly related to the quality of subsequent assembly as well as the performance and safety of the entire vehicle. For example, if the connection holes on the body frame have insufficient accuracy, it may lead to too large assembly gaps between components, affecting the overall rigidity and stability of the body; if there are deviations in the hinge installation holes on the door, it will cause the door to open and close smoothly, and even result in poor sealing.

[0003] Currently, the common drilling devices for automobile parts processing on the market usually adopt a design with a constant pressing force when drilling plates. This pressing method may be able to meet the basic processing requirements when drilling shallow holes, ensuring the relative stability of the plate during the drilling process. However, when it comes to deep hole drilling operations, the drawbacks gradually emerge. As the drilling depth continues to increase, the frictional force and cutting force between the drill bit and the plate will increase significantly. At this time, the constant pressing force can no longer effectively suppress the vibration of the plate caused by the force. Once the plate vibrates, it is difficult to keep the position of the drill bit stable during the drilling process, and it is easy to deviate, resulting in inconsistent hole diameters and rough hole walls, seriously affecting the drilling accuracy, so there is an urgent need for improvement.

[0074] Referring to Figures 1 to 9 An embodiment of a drilling device for processing automotive parts according to the present invention will be further described.

[0075] A drilling device for processing automotive parts includes a drilling base 1 and a control device 2 provided on the drilling base 1. A gusset plate 3 is fixedly provided on the drilling base 1. An adjustment groove 4 is formed in the gusset plate 3. A drilling table 5 is provided on the drilling base 1.

A plurality of groups of equally spaced built-in grooves 8 are formed in the conveying grooves 7. Two symmetrically arranged transverse grooves 9 are formed in the drilling table 5. The drilling device for processing automotive parts further includes:

[0076] A conveying mechanism, provided on the drilling table 5 and electrically connected to the control device 2, for conveying the plate to be drilled. The conveying mechanism includes:

[0077] A plurality of electric conveying rollers 10, which are equally spaced in the conveying groove 7 and electrically connected to the control device 2;

[0078] A settling member, provided in the built-in groove 8, and the settling member includes:

[0079] A vertical rod 11, fixedly provided in the built-in groove 8;

[0080] A settling block 12, slidably provided in the built-in groove 8, slidably connected to the vertical rod 11, and the settling block 12 is rotatably connected to the end of the electric conveying roller 10;

[0081] A settling spring 13, sleeved on the vertical rod 11, and the settling spring 13 is always in a compressed state.

[0082] After the drilling is completed, the control device 2 controls the hydraulic push rod 19 to start, so that the hydraulic push rod 19 resets, so that the plumb adjustment mechanism drives the drilling mechanism to reset, so that the plate after drilling loses the acting force on the pressing cover 34, and then the compressed settlement spring 13 releases elastic potential energy, so as to push the settlement block 12 to move away from the drilling base 1 in the built-in groove 8, so as to drive the electric conveying roller 10 rotatably connected to the settlement block 12 to reset, so as to push the drilled plate away from the surface of the drilling table 5, and the control device 2 controls the electric conveying roller 10 to start, so as to transport the drilled plate away.

[0083] Referring to Figures 1 to 9 , the limiting members, there are two groups, and the two groups of limiting members are symmetrically arranged on the drilling table 5, and the limiting members are used to limit the plate during transportation, and the limiting members include:

[0084] The electric push rods 14, there are multiple, and the multiple electric push rods 14 are equidistantly arranged in the horizontal groove 9, the electric push rods 14 are fixedly connected to the drilling table 5, and the electric push rods 14 are electrically connected to the control device 2;

[0085] The limiting plates 15 are fixedly arranged on the electric push rods 14, and the limiting plates 15 are used to limit the plate during transportation.

[0086] During operation, the plate to be drilled is placed on the electric conveying roller 10, and then the control device 2 controls the electric push rod 14 to start, so that the limiting plate 15 fixedly connected to the electric push rod 14 moves towards the plate until the limiting plates 15 on both sides of the plate fit on both sides of the plate, so as to limit the plate; then the control device 2 controls the electric conveying roller 10 to start, so that the electric conveying roller 10 drives the plate to be drilled to move below the drill bit 32 until the plate to be drilled moves directly below the drill bit 32;

[0087] By providing a conveying mechanism, the device can automatically move the plate to be drilled below the drill bit 32, and at the same time, the device can also limit the plate during transportation, thereby avoiding the deviation of the plate during transportation and reducing the subsequent drilling accuracy.

[0088] Referring to Figures 1 to 9 , the position adjustment part, is arranged on the arch plate 3 and is electrically connected to the control device 2, and the position adjustment part includes:

[0089] The position adjustment motor 16 is fixedly arranged on the arch plate 3 and is electrically connected to the control device 2;

[0090] The position-adjusting screw 17 is located in the position-adjusting groove 4. One end of the position-adjusting screw 17 close to the position-adjusting motor 16 is fixedly connected to the output end of the position-adjusting motor 16, and the end of the position-adjusting screw 17 far from the position-adjusting motor 16 is rotatably connected to the arch plate 3;

[0091] The position-adjusting block 18 is slidably arranged in the position-adjusting groove 4 and is in threaded connection with the position-adjusting screw 17;

[0092] The hydraulic push rod 19 is fixedly arranged on the surface of the position-adjusting block 18 close to the drilling table 5, and the hydraulic push rod 19 is electrically connected to the control device 2.

[0093] After the plate moves to directly below the drill bit 32, the control device 2 controls the position-adjusting motor 16 to start, so that the position-adjusting screw 17 fixedly connected to the output end of the position-adjusting motor 16 rotates. Through the threaded transmission cooperation between the position-adjusting screw 17 and the position-adjusting block 18, the position-adjusting block 18 slides in the position-adjusting groove 4, and further the hydraulic push rod 19 arranged on the position-adjusting block 18 drives the plumb mechanism to move, so that the drilling mechanism arranged on the plumb mechanism moves until the drill bit 32 in the drilling mechanism moves to directly above the position to be drilled on the plate; by providing the position-adjusting part, the device can adjust the position of the drilling mechanism, so that the device can perform drilling operations on different positions on the plate.

[0094] Refer to Figures 1 to 9 , the plumb mechanism is arranged on the position-adjusting part and is electrically connected to the control device 2. The plumb mechanism includes:

[0095] The carrier plate 20 is fixedly arranged at one end of the hydraulic push rod 19 close to the drilling table 5;

[0096] The plumb plate 21 is located directly below the carrier plate 20, and a plurality of through holes 22 evenly distributed in a circle are formed in the plumb plate 21;

[0097] There are multiple groups of plumb parts, and the multiple groups of plumb parts are evenly arranged in a circle on the carrier plate 20. The plumb parts are electrically connected to the control device 2 and are used to adjust the verticality when the drilling mechanism drills. The plumb parts include:

[0098] The plumb bolt 23 is rotatably arranged on the carrier plate 20, and the end of the plumb screw far from the arch plate 3 passes through the plumb plate 21 through the through hole 22;

[0099] The plumb nut 24 is arranged on the plumb bolt 23 in a threaded manner;

[0100] The driven gear roller 25 is fixedly arranged on the plumb nut 24, and the axis of the driven gear roller 25 coincides with the axis of the plumb nut 24;

[0101] The vertical adjustment motor 26 is arranged on the vertical adjustment plate 21 and is electrically connected to the control device 2;

[0102] The vertical adjustment shaft 27 is rotatably arranged on the carrier plate 20, and one end of the vertical adjustment shaft 27 close to the vertical adjustment motor 26 is fixedly connected to the output end of the vertical adjustment motor 26;

[0103] The driving gear 28 is fixedly arranged at one end of the vertical adjustment shaft 27 close to the drilling table 5, and the driving gear 28 meshes with the driven gear roller 25;

[0104] The verticality sensor 29 is arranged on the vertical adjustment plate 21 and is electrically connected to the control device 2. The verticality sensor 29 is used to measure in real time whether the axis of the adjacent vertical adjustment bolts 23 is perpendicular to the surface of the plate to be drilled.

[0105] Refer to Figures 1 to 9 , during the process of the drill bit 32 drilling the plate, each verticality sensor 29 monitors in real time the verticality of the adjacent vertical adjustment bolts 23 and the surface of the plate to be drilled. If a certain verticality sensor 29 detects that the verticality of the adjacent vertical adjustment bolts 23 and the surface of the plate to be drilled exceeds the preset verticality error range, at this time the control device 2 controls the corresponding vertical adjustment motor 26 to start, so that the vertical adjustment shaft 27 fixedly connected to the output end of the vertical adjustment motor 26 rotates, and then drives the driving gear 28 fixedly connected to the vertical adjustment shaft 27 to rotate. Through the meshing between the driving gear 28 and the driven gear roller 25, the driven gear rotates, and then the vertical adjustment nut 24 fixedly connected to the driven gear rotates. Through the threaded transmission cooperation between the vertical adjustment nut 24 and the vertical adjustment bolts 23, a force is applied to a part of the vertical adjustment plate 21 by the vertical adjustment nut 24, causing the vertical adjustment plate 21 to deform slightly, so as to adjust the verticality of the adjacent vertical adjustment bolts 23 and the surface of the plate to be drilled until the verticality of the adjacent vertical adjustment bolts 23 and the surface of the plate to be drilled meets the preset verticality error range again. By ensuring that the verticality of each vertical adjustment bolt 23 and the surface of the plate to be drilled meets the preset verticality error range, the drill bit 32 in the drilling mechanism arranged on the vertical adjustment plate 21 can also maintain the verticality with the plate;

[0106] By arranging the vertical adjustment mechanism, the device can monitor in real time the verticality between the drill bit 32 and the plate. When it is found that the verticality between the drill bit 32 and the plate exceeds the preset verticality error range, the verticality between the drill bit 32 and the plate can be adjusted in real time, thus greatly ensuring the drilling accuracy of the device for the plate.

[0107] Refer to Figures 1 to 9, a drilling mechanism, which is arranged on the plumb adjustment mechanism and electrically connected to the control device 2. The drilling mechanism is used for drilling the plate, and the drilling mechanism includes:

[0108] A drilling motor 30, which is fixedly arranged on the plumb adjustment plate 21 and electrically connected to the control device 2;

[0109] A mounting sleeve 31, which is fixedly arranged on the output end of the drilling motor 30, and the axis of the mounting sleeve 31 coincides with the axis of the plumb adjustment plate 21;

[0110] A drill bit 32, which is detachably and fixedly connected to the mounting sleeve 31, and the drill bit 32 is used for drilling the plate;

[0111] A pressing part, which is arranged on the plumb adjustment plate 21. The pressing part is used for pressing a part of the plate to be drilled, and the pressing part includes:

[0112] There are multiple connecting rods 33, and the multiple connecting rods 33 are evenly arranged in a circle on the surface of the plumb adjustment plate 21 close to the drilling table 5. The connecting rods 33 are fixedly connected to the plumb adjustment plate 21;

[0113] A pressing cover 34, which is sleeved on the periphery of the drill bit 32, and the inner diameter of the pressing cover 34 is larger than the outer diameter of the drill bit 32. A plurality of pressing grooves 35 are evenly distributed in a circle in the pressing cover 34. In the initial state, the distance between the pressing cover 34 and the drilling table 5 is less than the distance between the drill bit 32 and the drilling table 5. It should be noted that by providing the pressing cover 34, the drill chips generated during drilling are prevented from splashing and hurting people;

[0114] A baffle 36, which is slidably arranged in the pressing groove 35, and the baffle 36 is fixedly connected to the connecting rod 33;

[0115] A pressing spring 37, which is arranged in the pressing groove 35, and the pressing spring 37 is always in a compressed state.

[0116] Refer to Figures 1 to 9, during the process of the drill bit 32 moving towards the plate, the pressing cover 34 first contacts the drill bit 32 and the plate. When the pressing cover 34 contacts the plate and the drill bit 32 does not contact the plate, as the drill bit 32 continuously moves towards the plate, at this time, the connecting rod 33 arranged on the plumb bob adjusting plate 21 drives the baffle 36 to move towards the plate, so that the baffle 36 continuously presses the pressing spring 37, and the pressed pressing spring 37 exerts a continuously increasing force on the pressing cover 34, thereby enabling the pressing cover 34 to exert a continuously increasing force on the periphery of the position to be drilled on the plate. The plate moves towards the drilling base 1 under the force until the plate fits with the drilling table 5. At this time, through the cooperation of the pressing cover 34 and the drilling table 5, the periphery of the position to be drilled on the plate is pressed and fixed, thus avoiding the problem that the plate deviates during the drilling process of the plate, resulting in a decrease in drilling accuracy;

[0117] By arranging a drilling mechanism in this device, after the plate moves to the corresponding position, the device can automatically perform drilling on the plate. At the same time, as the drilling depth of the drill bit 32 increases, the pressing force of the pressing cover 34 on the plate also continuously increases, so as to match the drilling depth of the drill bit 32, avoiding the problem that the vibration amplitude of the plate increases with the increase of the drilling depth of the drill bit 32, resulting in a decrease in the drilling accuracy of the drill bit 32.

[0118] Refer to Figures 1 to 9 , an auxiliary part, is arranged on the pressing part. The auxiliary part is electrically connected to the control device 2. The auxiliary part is used to cool the drill bit 32 and clean the drill chips. The auxiliary part includes:

[0119] A liquid collecting tank 38 is arranged on the pressing cover 34, and a liquid discharge pipe 39 is arranged on the liquid collecting tank 38;

[0120] A liquid spraying pipe 40 is arranged on the liquid collecting tank 38. One end of the liquid spraying pipe 40 is located inside the pressing cover 34. A liquid spraying control valve 41 for controlling the liquid spraying of the liquid spraying pipe 40 is arranged on the liquid spraying pipe 40, and the liquid spraying control valve 41 is electrically connected to the control device 2;

[0121] A chip collecting tank 42 is arranged on the pressing cover 34, and a closing door 43 is rotatably arranged on the chip collecting tank 42;

[0122] A chip suction pipe 44 is arranged on the chip collecting tank 42, and one end of the chip suction pipe 44 is located inside the pressing cover 34. A chip suction control valve 45 for controlling the chip suction of the chip suction pipe 44 is arranged on the chip suction pipe 44, and the chip suction control valve 45 is electrically connected to the control device 2.

[0123] During the process of drilling the board with the drill bit 32, the liquid spraying control valve 41 and the chip suction control valve 45 are started by the control device 2. The start of the liquid spraying control valve 41 causes the coolant in the liquid collecting tank 38 to be sprayed onto the drilling position on the board through the liquid spraying pipe 40, thereby cooling the drill hole; the start of the chip suction control valve 45 causes the chip suction pipe 44 to suck the coolant and waste chips on the board into the chip collecting box 42;

[0124] By arranging an auxiliary part, when the device drills the board, the device can cool the drill bit 32, thereby extending the service life of the drill bit 32 to a certain extent and sucking the waste chips generated by drilling into the waste chip box, so that subsequent workers do not need to clean the drill chips, reducing the labor intensity of the workers to a certain extent.

[0125] Working principle: Refer to Figures 1 to 9 , during operation, place the board to be drilled on the electric conveying rollers 10, and then start the electric push rod 14 through the control device 2, so that the limiting plate 15 fixedly connected to the electric push rod 14 moves towards the board until the limiting plates 15 on both sides of the board are attached to both sides of the board, thereby limiting the board; then start the electric conveying rollers 10 through the control device 2, so that the electric conveying rollers 10 drive the board to be drilled to move under the drill bit 32 until the board to be drilled moves directly below the drill bit 32;

[0126] After the board moves directly below the drill bit 32, start the position adjustment motor 16 through the control device 2, so that the position adjustment screw rod 17 fixedly connected to the output end of the position adjustment motor 16 rotates. Through the threaded transmission cooperation between the position adjustment screw rod 17 and the position adjustment block 18, the position adjustment block 18 slides in the position adjustment groove 4, and then the hydraulic push rod 19 arranged on the position adjustment block 18 drives the plumb bob mechanism to move, so that the drilling mechanism arranged on the plumb bob mechanism moves until the drill bit 32 in the drilling mechanism moves directly above the position to be drilled on the board;

[0127] After the drill bit 32 moves to directly above the position on the plate where drilling is to be performed, the drilling motor 30 is started by the control device 2, so that the mounting sleeve 31 fixedly connected to the output end of the drilling motor 30 rotates, and then the drill bit 32 detachably and fixedly connected to the mounting sleeve 31 rotates. Then, the hydraulic push rod 19 is started by the control device 2, so that the carrier plate 20 fixedly connected to the hydraulic push rod 19 moves towards the plate, and then the plumb bolt 23 provided on the carrier plate 20 moves towards the plate, causing the plumb nut 24 threadedly connected to the plumb bolt 23 to move towards the plate, and then driving the plumb plate 21 to move towards the plate, so that the drilling motor 30 provided on the plumb plate 21 moves towards the plate, causing the mounting sleeve 31 fixedly connected to the output end of the drilling motor 30 to move towards the plate, and thus the drill bit 32 detachably and fixedly connected to the mounting sleeve 31 moves towards the plate until the drill bit 32 completes the drilling operation on the position on the plate where drilling is to be performed;

[0128] It should be noted that during the process of the drill bit 32 moving towards the plate, the pressing cover 34 first contacts the plate with the drill bit 32. When the pressing cover 34 contacts the plate and the drill bit 32 does not contact the plate, as the drill bit 32 continues to move towards the plate, at this time, the connecting rod 33 provided on the plumb plate 21 drives the baffle 36 to move towards the plate, so that the baffle 36 continuously presses the compression spring 37, causing the compressed compression spring 37 to exert a continuously increasing force on the pressing cover 34, and then causing the pressing cover 34 to exert a continuously increasing force on the periphery of the position on the plate where drilling is to be performed. The plate is forced to move towards the drilling base 1 until the plate fits with the drilling table 5. At this time, through the cooperation of the pressing cover 34 and the drilling table 5, the periphery of the position on the plate where drilling is to be performed is pressed and fixed, thus avoiding the reduction of drilling accuracy caused by the deviation of the plate during the drilling process of the plate;

[0129] Meanwhile, during the process of the drill bit 32 drilling the plate, each perpendicularity sensor 29 monitors in real time the perpendicularity between the adjacent leveling bolts 23 and the surface of the plate to be drilled. If a certain perpendicularity sensor 29 detects that the perpendicularity between the adjacent leveling bolts 23 and the surface of the plate to be drilled exceeds the preset perpendicularity error range, at this time, the control device 2 controls the corresponding leveling motor 26 to start, so that the leveling shaft 27 fixedly connected to the output end of the leveling motor 26 rotates, and then drives the driving gear 28 fixedly connected to the leveling shaft 27 to rotate. Through the meshing between the driving gear 28 and the driven gear roller 25, the driven gear rotates, and then the leveling nut 24 fixedly connected to the driven gear rotates. Through the threaded transmission cooperation between the leveling nut 24 and the leveling bolt 23, a force is applied to a part of the leveling plate 21 by the leveling nut 24, causing the leveling plate 21 to undergo a slight deformation, thereby adjusting the perpendicularity between the adjacent leveling bolts 23 and the surface of the plate to be drilled until the perpendicularity between the adjacent leveling bolts 23 and the surface of the plate to be drilled conforms to the preset perpendicularity error range again. By ensuring that the perpendicularity between each leveling bolt 23 and the surface of the plate to be drilled conforms to the preset perpendicularity error range, the drill bit 32 in the drilling mechanism provided on the leveling plate 21 can also maintain the perpendicularity with the plate;

[0130] During the process of the drill bit 32 drilling the plate, the control device 2 controls the liquid spraying control valve 41 and the chip suction control valve 45 to start. The start of the liquid spraying control valve 41 causes the coolant in the liquid collecting tank 38 to be sprayed onto the drilling position on the plate through the liquid spraying pipe 40, thereby cooling the drill hole; the start of the chip suction control valve 45 causes the chip suction pipe 44 to suck the coolant and waste chips on the plate into the chip collecting tank 42;

[0131] After the drilling is completed, the control device 2 controls the hydraulic push rod 19 to start, causing the hydraulic push rod 19 to reset, so that the leveling mechanism drives the drilling mechanism to reset, so that the plate after drilling loses the acting force of the pressing cover 34. Then, the compressed settlement spring 13 releases its elastic potential energy, thereby pushing the settlement block 12 to move away from the drilling base 1 in the built-in groove 8, and then driving the electric conveying roller 10 rotatably connected to the settlement block 12 to reset, thereby pushing the plate after drilling away from the surface of the drilling table 5. The control device 2 controls the electric conveying roller 10 to start, thereby transporting the plate after drilling away.
