[0004] At present, in the prior art, since the automobile pedal connecting rod is made of metal material, when the automobile pedal connecting rod is drilled, it will shake, the overall stability of the equipment is poor, which leads to inaccurate drilling, and in serious cases, the drill bit will be broken. SUMMARY

[0005] To solve the above technical problems, the application is implemented by the following technical scheme: A drilling equipment for automobile pedal connecting rod machining, comprising: A machine body and a driver installed at the top of the inner cavity of the machine body, a chip removal plate is fixedly installed on the edge side of the surface of the machine body and close to the driver; The drilling mechanism includes a lifting device and a servo motor. The lifting device is installed on the top of the machine body near the chip removal plate. The servo motor is installed on the surface of the lifting device. A three-jaw support frame is fixedly installed at the bottom of the servo motor surface. A drill bit is fixedly installed at the output end of the servo motor through a coupling. The drill bit passes through the center of the three-jaw support frame. A bent guide is fixedly installed on the side of the bottom of the servo motor. By rotating the output end of the servo motor, the drill bit can be driven to rotate. As the drill bit continues to move downward, it can drill holes in the automotive pedal connecting rod. The three-jaw support frame centers the drill bit, making the axis of the drill bit coincide with the axis of the output end of the servo motor. This makes the drilling smooth and accurate. Furthermore, the support of the drill bit by the three-jaw support frame increases the strength of the drill bit itself and makes it less prone to breakage. The feeding mechanism includes a rotator and a strip groove. The rotator is installed in the middle of the top of the machine body. The strip groove is opened on the side of the top of the rotator. A connecting sleeve is fixedly installed on the side of the bottom of the rotator. A U-shaped bent rod is slidably installed between the inside of the connecting sleeve and the inside of the strip groove. A semi-circular spring is fixedly installed at the end of the U-shaped bent rod near the connecting sleeve.

[0006] Preferably, the drill bit is installed vertically, and the outer surface of the drill bit is rotatably mounted between the center of the three-jaw support frame, and the bottom end of the bent guide is lower than the bottom end of the drill bit.

[0007] Preferably, the lifting device includes a support guide column, the bottom end of which is fixedly installed to the side of the top of the machine body by bolts. A slider is slidably installed on the outer circular surface of the support guide column. The surface of the servo motor is detachably fixed to the surface of the slider. A plate is fixedly installed on the top of the support guide column, and a hydraulic cylinder is fixedly installed on the top of the plate. The telescopic end of the hydraulic cylinder is fixedly installed to the side of the top of the slider. By extending the telescopic end of the hydraulic cylinder, a downward pushing force can be applied to the slider, causing the servo motor to move downward along with the slider. The drill bit is also driven downward by the servo motor, thereby adjusting the height of the drill bit.

[0008] Preferably, the support guide column is installed vertically, there are two support guide columns, and the two support guide columns are installed symmetrically along the chip removal plate, and the hydraulic cylinder is installed vertically.

[0009] Preferably, the connecting sleeve is installed directly below the strip groove, the top of the surface of the U-shaped bend is in contact with the inner wall of the strip groove, and the bottom of the surface of the U-shaped bend is in contact with the inner wall of the connecting sleeve.

[0010] Preferably, the rotator includes an annular bushing and a worktable. The annular bushing is fixedly installed at the middle of the top of the machine body. The central shaft at the bottom of the worktable is rotatably installed between the annular bushing and the top of the machine body. The bottom end of the central shaft of the worktable is fixedly installed to the output end of the driver through a coupling. The top of the connecting sleeve is fixedly installed to the bottom of the worktable. The end of the semi-circular spring away from the U-shaped bend is fixedly installed to the bottom of the worktable. A material discharge trough is provided on the side of the top of the worktable near the strip groove. A chip removal hole is provided on the bottom of the worktable near the bottom of the inner cavity of the material discharge trough. The groove on the bottom of the bending guide is engaged with the side of the top of the U-shaped bend, so that the bending guide matches the U-shaped bend. By continuously moving the bending guide downward, the servo motor can be guided through the bending guide, so that the servo motor and the drill bit move downward smoothly.

[0011] Preferably, the chip removal hole penetrates the workbench, there are four material feeding troughs, and the four material feeding troughs are evenly distributed on the side of the top of the workbench, and the strip groove is connected to the material feeding troughs.

[0012] By utilizing the inclined surface at the bottom of the bent guide to contact the end of the U-shaped rod away from the worktable, and by moving the bent guide downward, the bent guide applies an inward pushing force to the U-shaped rod. Under the sliding connection of the connecting sleeve and guided by the strip groove, the top of the U-shaped rod moves closer to the inside of the feeding trough. The semi-circular spring is elastically deformed by the compression of the bottom end of the U-shaped rod, and by utilizing the contact between the top of the U-shaped rod and the surface of the automotive pedal connecting rod blank in the feeding trough, the automotive pedal connecting rod blank can be clamped and fixed without any displacement.

[0013] Preferably, there are four U-shaped bends, which are evenly distributed along the edge of the workbench surface. There are also four semi-circular springs, which are evenly distributed along the bottom of the workbench. The automotive pedal connecting rod blank is placed into the feeding trough by an external robotic arm, which initially limits the position of the blank, preventing it from shifting or tilting. The rotation of the driver output can rotate the workbench, causing the automotive pedal connecting rod blank in the feeding trough to rotate as well, thus enabling feeding.

[0014] Preferably, a discharge mechanism is installed on the side of the top of the machine body. The discharge mechanism includes an H-shaped frame. The bottom of the H-shaped frame is fixedly installed to the side of the top of the machine body by screws. A U-shaped plate is slidably installed on the top of the H-shaped frame. The opening of the U-shaped plate faces the U-shaped bend. A reset spring is fixedly installed on the bottom of the U-shaped plate and the inner side of the H-shaped frame. An air pump is fixedly installed in the middle of the top of the U-shaped plate. A suction head is slidably installed on the end of the U-shaped plate away from the air pump. A spring is fixedly installed between the bottom of the suction head surface and the bottom of the U-shaped plate. A bending connecting rod is fixedly installed in the middle of the bottom of the U-shaped plate. An arc-shaped pressure plate is fixedly installed at the bottom end of the bending connecting rod. The suction head is subjected to a reverse force through the conical bucket at the bottom of the suction head contacting the top of the car pedal connecting rod, causing the suction head to move upward and compress the spring, achieving flexible contact and preventing damage to the car pedal connecting rod and the equipment. By utilizing the suction force generated by the air pump, and with the connection of the hose, a negative pressure is formed inside the suction head, which can hold the drilled car pedal connecting rod. As the U-shaped rod continues to move, the U-shaped rod separates from the arc-shaped pressure plate, the pressure on the arc-shaped pressure plate disappears, and under the elastic force of the reset spring, the U-shaped plate drives the suction head to move upward, thus raising and unloading the car pedal connecting rod.

[0015] Preferably, the bottom of the suction head is conical and funnel-shaped, there are two suction heads, and the two suction heads are symmetrically installed along the central axis of the middle of the U-shaped plate. The air port at the top of the suction head is connected to the air port of the suction pump through a flexible tube, and the suction head passes through the center of the spring.

[0016] This invention provides a device for testing the performance of near-infrared absorbing materials based on spectral analysis. It has the following beneficial effects: 1. The drilling equipment for processing automotive pedal connecting rods utilizes the rotation of the output end of a servo motor to drive the drill bit to rotate. As the drill bit continues to move downwards, it can perform drilling on the automotive pedal connecting rod. A three-jaw support frame is used to center the drill bit, ensuring that the axis of the drill bit coincides with the axis of the output end of the servo motor. This results in smooth and accurate drilling, and the support of the drill bit by the three-jaw support frame increases the strength of the drill bit itself, making it less prone to breakage.

[0017] 2. The drilling equipment for processing the automotive pedal connecting rod utilizes the extension of the hydraulic cylinder's telescopic end to apply a downward pushing force to the slider, causing the servo motor to move downward along with the slider, and the drill bit to be driven downward by the servo motor, thereby adjusting the height of the drill bit.

[0018] 3. The drilling equipment for processing the automotive pedal connecting rod, as the servo motor moves downward, the bending guide will move downward along with the servo motor. The groove at the bottom of the bending guide surface is engaged with the side of the top of the U-shaped bend, so that the bending guide fits into the U-shaped bend. By continuously moving the bending guide downward, the servo motor can be guided through the bending guide, so that the servo motor and the drill bit move downward smoothly.

[0019] IV. The drilling equipment for processing the car pedal connecting rod can initially limit the position of the car pedal connecting rod blank by placing it into the feeding trough, making it less likely to deviate or tilt. By rotating the output end of the driver, the worktable can be rotated, causing the car pedal connecting rod blank in the feeding trough to rotate together, thus enabling feeding through the rotation of the car pedal connecting rod blank.

[0020] 5. The drilling equipment for processing the car pedal connecting rod uses a bending guide to apply an inward pushing force to the U-shaped rod, causing the top of the U-shaped rod to move closer to the inside of the feeding trough. The semi-circular spring sheet will be elastically deformed by the compression of the bottom of the U-shaped rod, and the top of the U-shaped rod will contact the surface of the car pedal connecting rod blank in the feeding trough, thus clamping and fixing the car pedal connecting rod blank without any displacement.

[0021] VI. The drilling equipment for processing the car pedal connecting rod uses a conical bucket at the bottom of the suction head to contact the top of the car pedal connecting rod. The suction head is subjected to a reverse force, causing it to move upward and compress the spring, achieving flexible contact and preventing damage to the car pedal connecting rod and the equipment.

[0022] VII. The drilling equipment for processing the car pedal connecting rod utilizes the negative pressure created inside the suction head to hold the drilled car pedal connecting rod. As the U-shaped curved rod continues to move, it separates from the arc-shaped pressure plate, the pressure on the arc-shaped pressure plate disappears, and under the elastic force of the reset spring, the U-shaped plate drives the suction head to move upward, thus raising and unloading the car pedal connecting rod.

[0025] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] For the first embodiment, please refer to... Figures 1-4 The present invention provides a technical solution: A drilling device for machining automotive pedal connecting rods, comprising: The machine body 1, and the driver 2 installed on the top of the inner cavity of the machine body 1, and the chip removal plate 3 is fixedly installed on the side of the surface of the machine body 1 and near the driver 2. The drilling mechanism 5 includes a lifting device 51 and a servo motor 52. The lifting device 51 is installed on the top of the machine body 1 and near the chip conveyor plate 3. The servo motor 52 is installed on the surface of the lifting device 51. A three-jaw support frame 53 is fixedly installed on the bottom of the surface of the servo motor 52. A drill bit 54 is fixedly installed on the output end of the servo motor 52 through a coupling. The drill bit 54 passes through the center of the three-jaw support frame 53. A bending guide 55 is fixedly installed on the side of the bottom of the servo motor 52. When the servo motor 52 is turned on... 2. To perform the operation, the rotation of the output end of the servo motor 52 drives the drill bit 54 to rotate. As the drill bit 54 continues to move downward, it can drill holes in the car pedal connecting rod. The three-jaw support frame 53 is used to center the drill bit 54, so that the axis of the drill bit 54 coincides with the axis of the output end of the servo motor 52. This makes the rotation of the drill bit 54 smooth and accurate. In addition, the support of the drill bit 54 by the three-jaw support frame 53 can increase the strength of the drill bit 54 and make it less likely to break. The drill bit 54 is installed vertically, and its outer circular surface is rotated between the center of the three-jaw support frame 53. The bottom end of the bent guide 55 is lower than the bottom end of the drill bit 54.

[0027] The lifting device 51 includes a support guide column 511. The bottom end of the support guide column 511 is fixedly installed to the side of the top of the machine body 1 by bolts. A slider 512 is slidably installed on the outer surface of the support guide column 511. The surface of the servo motor 52 is detachably fixed to the surface of the slider 512. A plate 514 is fixedly installed on the top of the support guide column 511. A hydraulic cylinder 513 is fixedly installed on the top of the plate 514. The telescopic end of the hydraulic cylinder 513 is fixedly installed to the side of the top of the slider 512. With the support of the support guide column 511 and the plate 514, the hydraulic cylinder 513 is activated to operate. By extending the telescopic end of the hydraulic cylinder 513, a downward pushing force can be applied to the slider 512, causing the servo motor 52 to move downward along with the slider 512. The drill bit 54 will also be driven downward by the servo motor 52, thereby adjusting the height of the drill bit 54. After the drilling of the car pedal connecting rod is completed, the retraction of the telescopic end of the hydraulic cylinder 513 can apply an upward pulling force to the slider 512, causing the slider 512 to drive the servo motor 52 and the drill bit 54 to move upward together. The drill bit 54 separates from the drilled car pedal connecting rod, making it easier to transfer the car pedal connecting rod.

[0028] The support guide column 511 is installed vertically. There are two support guide columns 511, and the two support guide columns 511 are installed symmetrically along the chip removal plate 3. The hydraulic cylinder 513 is installed vertically.

[0029] The second embodiment is based on the first embodiment; please refer to [link / reference]. Figures 1 to 7 As shown: The feeding mechanism 4 includes a rotator 41 and a strip groove 42. The rotator 41 is installed in the middle of the top of the machine body 1. The strip groove 42 is opened on the side of the top of the rotator 41. A connecting sleeve 43 is fixedly installed on the side of the bottom of the rotator 41. A U-shaped bent rod 44 is slidably installed between the inside of the connecting sleeve 43 and the inside of the strip groove 42. A semi-circular spring piece 45 is fixedly installed at the end of the U-shaped bent rod 44 and near the connecting sleeve 43. As the servo motor 52 moves downward, the bending guide 55 moves downward with the servo motor 52. The groove at the bottom of the bending guide 55 is engaged with the side of the top of the U-shaped bent rod 44, so that the bending guide 55 matches the U-shaped bent rod 44. By continuously moving downward, the bending guide 55 can guide the servo motor 52, so that the servo motor 52 and the drill bit 54 move downward smoothly.

[0030] The connecting sleeve 43 is installed directly below the strip groove 42. The top of the surface of the U-shaped bend 44 is in contact with the inner wall of the strip groove 42, and the bottom of the surface of the U-shaped bend 44 is in contact with the inner wall of the connecting sleeve 43.

[0031] The rotator 41 includes an annular bushing 411 and a worktable 412. The annular bushing 411 is fixedly installed at the middle of the top of the machine body 1. The central shaft at the bottom of the worktable 412 is rotatably installed between the annular bushing 411 and the top of the machine body 1. The bottom end of the central shaft of the worktable 412 is fixedly installed to the output end of the driver 2 through a coupling. The top of the connecting sleeve 43 is fixedly installed to the bottom of the worktable 412. The end of the semi-circular spring 45 away from the U-shaped bent rod 44 is fixedly installed to the bottom of the worktable 412. A discharge trough 413 is provided on the side of the top of the worktable 412 near the strip groove 42. A chip discharge hole 414 is provided at the bottom of the worktable 412 near the bottom of the inner cavity of the discharge trough 413.

[0032] An external robotic arm places the automotive pedal connecting rod blank into the feeding trough 413, thus initially limiting its position and preventing it from shifting or tilting. The driver 2 is then activated, rotating the worktable 412 and causing the automotive pedal connecting rod blank in the feeding trough 413 to rotate as well. This allows for feeding via the movement of the blank. When the blank reaches directly below the drill bit 54, the driver 2 is paused to stop the blank's movement. The remaining blank, evenly distributed on the top side of the worktable 412, is then placed into the feeding trough 413, ensuring orderly feeding without misalignment.

[0033] Chip removal hole 414 penetrates the workbench 412, there are four material discharge troughs 413, and the four material discharge troughs 413 are evenly distributed on the side of the top of the workbench 412. The strip groove 42 is connected to the material discharge trough 413.

[0034] By utilizing the inclined surface at the bottom of the bent guide 55 to contact the end of the U-shaped rod 44 away from the worktable 412, and by moving the bent guide 55 downward, the bent guide 55 applies an inward pushing force to the U-shaped rod 44. Under the sliding connection of the connecting sleeve 43 and the guidance of the strip groove 42, the top end of the U-shaped rod 44 moves closer to the interior of the discharge trough 413. The semi-circular spring 45 is elastically deformed by the compression of the bottom end of the U-shaped rod 44. By utilizing the top end of the U-shaped rod 44 to contact the surface of the automobile pedal connecting rod blank in the discharge trough 413, the automobile pedal connecting rod blank can be clamped and fixed without any displacement.

[0035] There are four U-shaped bends 44, which are evenly distributed on the edge of the worktable 412 surface. There are four semi-circular spring pieces 45, which are evenly distributed on the bottom of the worktable 412.

[0036] The third embodiment is based on the first and second embodiments; please refer to [link / reference]. Figures 1 to 9 As shown: A discharge mechanism 6 is installed on the side of the top of the machine body 1. The discharge mechanism 6 includes an H-shaped frame 61. The bottom of the H-shaped frame 61 is fixedly installed to the side of the top of the machine body 1 by screws. A U-shaped plate 62 is slidably installed on the top of the H-shaped frame 61. The opening of the U-shaped plate 62 faces the U-shaped bend 44. A reset spring 63 is fixedly installed on the bottom of the U-shaped plate 62 and the inner side of the H-shaped frame 61. An air suction pump 64 is fixedly installed in the middle of the top of the U-shaped plate 62. The U-shaped plate 62 is away from the air suction pump 64. A suction head 65 is slidably mounted on one end of the suction pump 64. A spring 66 is fixedly installed between the bottom of the suction head 65 and the bottom of the U-shaped plate 62. A bending connecting rod 67 is fixedly installed at the middle of the bottom of the U-shaped plate 62. An arc-shaped pressure plate 68 is fixedly installed at the bottom end of the bending connecting rod 67. As the bending guide 55 moves upward, the pushing force of the bending guide 55 on the U-shaped bending rod 44 disappears, and under the elastic force of the semi-circular spring plate 45, the U-shaped bending rod 44 is forced to move upward. As the U-shaped bend 44 moves outward, its top end separates from the drilled car pedal connecting rod. The rotation of the worktable 412 allows the drilled car pedal connecting rod to be moved outward, shifting it closer to the suction head 65. The bottom of the U-shaped bend 44 contacts the surface of the arc-shaped pressure plate 68, causing the arc-shaped pressure plate 68 to be subjected to downward pressure from the U-shaped bend 44. Combined with the sliding support of the H-shaped frame 61 on the U-shaped plate 62, the pressure on the arc-shaped pressure plate 68 causes the reset spring 63 to deform elastically. Through the connection of the bending link 67, the U-shaped plate 62 drives the suction head 65 downward. The conical hopper at the bottom of the suction head 65 contacts the top of the car pedal connecting rod, causing the suction head 65 to be subjected to a reverse force, moving it upward and compressing the spring 66. This achieves flexible contact, minimizing damage to the car pedal connecting rod and the equipment.

[0037] The bottom of the suction head 65 is conical and funnel-shaped. There are two suction heads 65, which are symmetrically installed along the central axis of the U-shaped plate 62. The air port at the top of the suction head 65 is connected to the air port of the suction pump 64 through a hose. The suction head 65 passes through the center of the spring 66. The suction pump 64 is turned on and starts working. Using the suction force generated by the suction pump 64 and the connection of the hose, a negative pressure is formed inside the suction head 65, which can suck up the drilled car pedal connecting rod. As the U-shaped bent rod 44 continues to move, the U-shaped bent rod 44 separates from the arc-shaped pressure plate 68. The pressing force on the arc-shaped pressure plate 68 disappears, and under the elastic force of the reset spring 63, the U-shaped plate 62 drives the suction head 65 to move upward, which can lift the car pedal connecting rod for unloading. This helps the car pedal connecting rod to be picked up by an external robotic arm.

[0038] In use, the car pedal connecting rod blank is first placed into the feeding trough 413 by an external robotic arm. This initially limits the position of the car pedal connecting rod blank, preventing it from shifting or tilting. The operator then starts the driver 2. The rotation of the output end of the driver 2 drives the worktable 412 to rotate, causing the car pedal connecting rod blank in the feeding trough 413 to rotate as well. The car pedal connecting rod blank is then fed through its rotation. When the car pedal connecting rod blank rotates to directly below the drill bit 54, the driver 2 is stopped, stopping the rotation of the car pedal connecting rod blank. The car pedal connecting rod blank is then placed into the feeding trough 413, which is evenly distributed on the top side of the worktable 412, allowing for orderly feeding without any misalignment. The operator activates the hydraulic cylinder 513 to work. By extending the telescopic end of the hydraulic cylinder 513, a downward pushing force can be applied to the slider 512, causing the servo motor 52 to move downward along with the slider 512. The drill bit 54 will be driven downward by the servo motor 52, thereby adjusting the height of the drill bit 54. Simultaneously, the inclined surface at the bottom of the bending guide 55 contacts the end of the U-shaped rod 44 away from the worktable 412, and the bending guide 55 moves downward, applying an inward pushing force to the U-shaped rod 44. Under the sliding connection of the connecting sleeve 43 and the guidance of the strip groove 42, the top of the U-shaped rod 44 moves closer to the inside of the feeding trough 413. The semi-circular spring 45 will be elastically deformed by the pressure of the bottom end of the U-shaped rod 44, and the top of the U-shaped rod 44 contacts the surface of the automobile pedal connecting rod blank in the feeding trough 413, so that the automobile pedal connecting rod blank can be clamped and fixed without any displacement. The operator then starts the servo motor 52. The rotation of the output end of the servo motor 52 drives the drill bit 54 to rotate. As the drill bit 54 continues to move downward, it can drill holes in the car pedal connecting rod. The three-jaw support frame 53 is used to center the drill bit 54, so that the axis of the drill bit 54 coincides with the axis of the output end of the servo motor 52. This makes the drill bit 54 rotate and drill smoothly and accurately. In addition, the support of the three-jaw support frame 53 increases the strength of the drill bit 54 and makes it less likely to break. After the car pedal connecting rod is drilled, the retraction of the extension end of the hydraulic cylinder 513 can apply an upward pulling force to the slider 512, causing the slider 512 to drive the servo motor 52 and the drill bit 54 to move upward together, and the drill bit 54 separates from the car pedal connecting rod after drilling. Furthermore, as the bending guide 55 moves upward, the pushing force of the bending guide 55 on the U-shaped bend 44 disappears, and under the elastic force of the semi-circular spring 45, the U-shaped bend 44 moves outward. The top of the U-shaped bend 44 separates from the drilled car pedal connecting rod, and by utilizing the rotation of the worktable 412, the drilled car pedal connecting rod can be moved out, causing the car pedal connecting rod to move closer to the suction head 65. The bottom of the U-shaped bend 44 then contacts the surface of the arc-shaped pressure plate 68, causing the arc-shaped pressure plate 68 to be subjected to U-shaped pressure. The downward pressing force of the curved rod 44, combined with the sliding support of the H-shaped frame 61 on the U-shaped plate 62, and the pressing force on the arc-shaped pressure plate 68, causes the reset spring 63 to be pressed and elastically deformed. Through the connection of the curved connecting rod 67, the U-shaped plate 62 drives the suction head 65 to move downward. Through the conical bucket at the bottom of the suction head 65 contacting the top of the car pedal connecting rod, the suction head 65 will be subjected to a reverse force, causing the suction head 65 to move upward and squeeze the spring 66, achieving flexible contact and preventing damage to the car pedal connecting rod and equipment. At this time, the suction pump 64 is turned on. The suction force generated by the suction pump 64, and with the connection of the hose, creates a negative pressure inside the suction head 65, which can hold the drilled car pedal connecting rod. As the U-shaped bent rod 44 continues to move, the U-shaped bent rod 44 separates from the arc-shaped pressure plate 68. The pressing force on the arc-shaped pressure plate 68 disappears, and under the elastic force of the reset spring 63, the U-shaped plate 62 drives the suction head 65 to move upward, which can lift the car pedal connecting rod for unloading. This facilitates the removal of the car pedal connecting rod by the external equipment robot. This cycle is repeated to perform batch drilling. The chips generated during drilling fall from the chip discharge hole 414 and the edge of the worktable 412 onto the chip discharge plate 3 for chip removal.
