Description

Technical Field

[0001] This invention relates to a method for manufacturing a fixed cover plate for trailers. Background Technology

[0002] A trailer is a vehicle that is towed by a car but has no power drive itself.

[0003] Fixed cover plates are used on trailers to secure them with suspension hooks, achieving a stable connection between the truck cab and the cargo box. The existing fixed cover plate manufacturing process is relatively complex and has low processing precision, which increases the scrap rate of fixed cover plates. Summary of the Invention

[0004] The purpose of this invention is to provide a technical solution for manufacturing a trailer cover plate, which addresses the shortcomings of existing technologies. This manufacturing method has simple steps, facilitates automatic loading and unloading of the cover plate, improves processing efficiency and accuracy, and reduces scrap rate.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A method for manufacturing a trailer cover plate, characterized by comprising the following steps:

[0007] 1) Casting

[0008] a. First, a mold is made according to the design dimensions of the fixed cover plate, and the required fixed cover plate is formed by casting.

[0009] b. Then, after cooling and demolding, the material is conveyed to the drilling equipment for processing. The drilling equipment consists of a first box and a second box. The second box is fixed on the top surface of the first box, and the drilling mechanism inside the second box moves to the side close to the back plate of the second box.

[0010] 2) Fixed cover plate input feeding

[0011] a. Open the cabinet door on the drilling equipment, and send the cast and molded fixed cover plate upside down into the conveying mechanism through the robotic arm. The extension component on the conveying mechanism moves downward and inserts into the first through hole on the fixed cover plate. Activate the extension component to clamp and position the fixed cover plate, and then drive the fixed cover plate to move horizontally to the set position in the second box through the conveying mechanism.

[0012] b. Then, the fixed cover plate is lowered onto the rotating mechanism via the conveying mechanism and the extension component, so that the positioning ring on the fixed cover plate is put into the support sleeve of the rotating mechanism, and the support sleeve abuts against the annular surface between the first through hole and the positioning ring.

[0013] c. Next, observe the position of the mounting block on the fixed cover through the window on the cabinet door or the visual sensor inside the second box, and control the rotation mechanism to rotate through the control panel on the cabinet door so that the mounting block is respectively limited to each clamping component on the rotation mechanism.

[0014] 3) Fixing the cover plate

[0015] a. After the installation block is aligned with the clamping assembly, start each clamping assembly to clamp the installation block.

[0016] b. Then retract the extension assembly to detach it from the fixed cover plate, and raise the extension assembly above the drilling mechanism via the conveying mechanism.

[0017] 4) Drill holes for fixing the cover plate

[0018] a. After the conveying components are moved into place, start the drilling mechanism to drill holes in the fixed cover plate.

[0019] b. After one hole is completed, lift the drilling mechanism, start the rotating mechanism, and drive the fixed cover plate to rotate to the next processing position to process another hole until the mounting hole, the second through hole and the third through hole on the fixed cover plate are completed.

[0020] 5) Fixed cover plate output feeding

[0021] a. The drilling mechanism moves to the side close to the back plate of the second housing, starts the conveying mechanism, lowers the extension component into the first through hole on the fixed cover, opens the extension component, and releases the clamping component at the same time.

[0022] b. Then, start the conveying mechanism to lift the fixed cover to the set position and transport it to the cabinet door. Then, replace the next fixed cover with an external robot arm.

[0023] 6) Polishing

[0024] The fixed cover plate after processing is polished using a grinding machine.

[0025] The manufacturing method is simple and not only facilitates the automatic loading and unloading of the fixed cover plate, but also improves the processing efficiency of the fixed cover plate, increases processing accuracy, and reduces the scrap rate.

[0026] Furthermore, the conveying mechanism includes side plates, a support frame, a lifting plate, a hoisting assembly, and an extension assembly. The support frame is located between two side plates, and a first roller is connected to the outer side of the side plates. A third slide rail is provided inside the second housing, and the first roller is limited to the third slide rail. A sixth motor is provided on the side plate, and the output shaft of the sixth motor is connected to the first roller. The lifting plate is connected to the lower part of the support frame via a telescopic rod. The hoisting assembly is located on the support frame and drives the lifting plate to move up and down. The extension assembly is located on the lifting plate. The side plates improve the stability and reliability of the support frame installation. By driving the first roller to rotate through the sixth motor, the conveying mechanism can move along the third slide rail to convey the fixed cover plate. The telescopic rod improves the stability and reliability of the lifting plate movement, preventing the lifting plate from tilting and affecting the movement accuracy of the extension assembly, ensuring that the fixed cover plate can be conveyed normally. The hoisting assembly can drive the lifting plate to move up and down, and then drive the fixed cover plate to move through the extension assembly. The extension assembly facilitates the clamping of the fixed cover plate.

[0027] Furthermore, the hoisting assembly includes a winding machine, a pull rope, guide wheels, and lifting lugs. The winding machine is mounted on a support frame, the guide wheels are connected to the support frame via a suspension block, and the lifting lugs are located on the top surface of the lifting plate. The winding machine connects to the lifting lugs via the pull rope that passes around the guide wheels. The winding machine drives the pull rope to move, which in turn drives the lifting plate to move via the lifting lugs. The suspension block improves the stability and reliability of the guide wheel installation, and the guide wheels help improve the stability of the pull rope movement.

[0028] Furthermore, the expansion components include an air pump, an air supply pipe, and a fixed pipe. The air pump and the fixed pipe are respectively located on the upper and lower sides of the lifting plate. The air pump is connected to the fixed pipe through the air supply pipe. A second cylinder is evenly arranged on the outer circumferential side of the fixed pipe. The second cylinder is equipped with a support rod and a diverter pipe is connected to the second cylinder. The diverter pipe is connected to the air supply pipe through a guide pipe. The second cylinder can be controlled to work by the air pump through the air supply pipe, which in turn can control the extension or retraction of the support rod to meet the requirements of fixed cover plate conveying. The air supply pipe can divert the gas through the diverter pipe through the guide pipe to control the movement of each support rod.

[0029] Furthermore, the rotating mechanism includes a turntable and a first motor. A rotating shaft is provided on the bottom surface of the turntable, and the rotating shaft vertically penetrates the top surface of the first housing. An external gear ring is provided at the bottom of the rotating shaft. The first motor is located inside the first housing, and the output shaft of the first motor is connected to a drive gear. The drive gear meshes with the external gear ring. A support sleeve and a clamping assembly are provided on the top surface of the turntable. The support sleeve is located at the center of the turntable, and the clamping assembly is distributed in a ring on the turntable. The first motor drives the external gear ring to rotate via the drive gear, which in turn drives the turntable to rotate via the rotating shaft, thereby adjusting the fixed cover plate to meet the drilling requirements at different positions. The support sleeve is used to position and support the fixed cover plate, and the clamping assembly is used to clamp the mounting block, improving the stability and reliability of the fixed cover plate during drilling.

[0030] Furthermore, the clamping assembly includes a first slide rail, a second motor, a first screw, a clamping block, and a first stop. The second motor and the first stop are mounted on the turntable. The second motor is connected to the first stop via the first screw. The first screw has two threaded sections with opposite rotation directions. The two first slide rails are parallel to each other on the turntable and located on both sides of the first screw. The clamping block is movably connected to the first slide rail and has a sliding groove that matches the first slide rail. A first push block is provided on the bottom surface of the clamping block and is mounted on the first screw. The clamping block has an anti-slip strip. The second motor drives the first screw to rotate, and the first push block can then drive the clamping block to move along the second slide rail, thus achieving the clamping requirements of the fixed cover plate. The anti-slip strip can improve the stability and reliability of the clamping of the mounting block and prevent slippage during drilling, which would affect the machining accuracy and quality of the fixed cover plate.

[0031] Furthermore, support blocks are evenly distributed in a ring on the bottom surface of the turntable, and a second roller is provided on the support block. The second roller is supported on the top surface of the first box. The design of the support block and the second roller not only helps to improve the stability and reliability of the turntable when rotating, but also provides support when drilling holes in the fixed cover plate to prevent the turntable from tilting.

[0032] Furthermore, the drilling mechanism includes an X-axis moving component, a Y-axis moving component, and a drilling component. The X-axis moving component is located on the inner wall of the second housing, the Y-axis moving component is located between the two X-axis moving components, and the drilling component is located on the Y-axis moving component. The drilling component is moved by the X-axis moving component and the Y-axis moving component, thereby meeting the drilling requirements at different positions on the fixed cover plate.

[0033] Furthermore, the thickness of the support sleeve is less than the width of the annular surface, which is beneficial for extending the support of the fixed cover plate and meeting the requirements for conveying the fixed cover plate.

[0034] The present invention, by adopting the above-described technical solution, has the following beneficial effects:

[0035] 1. The manufacturing method has simple steps, which not only facilitates the automatic loading and unloading of the fixed cover plate, but also improves the processing efficiency of the fixed cover plate, increases the processing accuracy, and reduces the scrap rate.

[0036] 2. The side plate improves the stability and reliability of the support frame installation. The first roller is rotated by the sixth motor, which can make the conveying mechanism move along the third slide rail to convey the fixed cover plate. The telescopic rod improves the stability and reliability of the lifting plate movement, avoids the lifting plate tilting and affecting the movement accuracy of the extension component, and ensures that the fixed cover plate can be conveyed normally. The hoisting component can drive the lifting plate to move up and down, and then drive the fixed cover plate to move through the extension component. The extension component makes it easy to clamp the fixed cover plate.

[0037] 3. The second cylinder can be controlled by the air pump through the air supply pipe, which in turn can control the extension or retraction of the support rod to meet the requirements of the fixed cover plate conveying. The air supply pipe can be used to divert the gas through the guide pipe and the distributor pipe to control the movement of each support rod.

[0038] 4. The first motor drives the external gear ring to rotate via the drive gear, which in turn drives the turntable to rotate via the rotating shaft, thereby adjusting the fixed cover plate to meet the drilling requirements at different positions. The support sleeve is used to position and support the fixed cover plate, and the clamping assembly is used to clamp the mounting block, improving the stability and reliability of the fixed cover plate during drilling.

Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion.

[0054] like Figures 1 to 10As shown, this invention discloses a method for manufacturing a trailer fixing cover. The fixing cover specifically includes a plate body 1. Three mounting blocks 2 are evenly distributed in a ring on the top surface of the plate body 1. Each mounting block 2 is provided with a mounting hole 6. A first through hole 3 is provided in the center of the plate body 1. A positioning ring 4 is provided on the same side of the center of the plate body 1 and the mounting block 2. An annular surface 5 is formed between the positioning ring 4 and the first through hole 3. Through grooves 7, second through holes 8 and third through holes 9 are evenly distributed in a ring on the plate body 1.

[0055] The manufacturing method includes the following steps:

[0056] 1) Casting

[0057] a. First, a mold is made according to the design dimensions of the fixed cover plate, and the required fixed cover plate is formed by casting.

[0058] b. Then, after cooling and demolding, the material is conveyed to the drilling equipment for processing. The drilling equipment consists of a first housing 10 and a second housing 11. The second housing 11 is fixed on the top surface of the first housing 10. The drilling mechanism 16 inside the second housing 11 moves to the side close to the back plate of the second housing 11. The first housing 10 is equipped with a power supply box, and the cabinet door 12 of the second housing 11 is equipped with a control panel 13. The control panel 13 is electrically connected to the power supply box.

[0059] 2) Fixed cover plate input feeding

[0060] a. Open the cabinet door 12 on the drilling equipment, and send the cast and molded fixed cover plate upside down into the conveying mechanism 15 through the robotic arm. The extension component on the conveying mechanism 15 moves downward and inserts into the first through hole 3 on the fixed cover plate. Start the extension component to clamp and position the fixed cover plate, and then drive the fixed cover plate to move horizontally to the set position in the second box 11 through the conveying mechanism 15.

[0061] The conveying mechanism 15 includes side plates 51, a support frame 54, a lifting plate 59, a hoisting assembly, and an extension assembly. The support frame 54 is located between the two side plates 51. A first roller 52 is connected to the outer side of the side plates 51. A third slide rail 50 is provided inside the second housing 11. The first roller 52 is limited to the upper and lower third slide rails 50. A sixth motor 53 is provided on the side plates 51. The output shaft of the sixth motor 53 is connected to the first roller 52. The lifting plate 59 is connected to the lower part of the support frame 54 via a telescopic rod 60. The hoisting assembly is located on the support frame 54 and drives the lifting plate 59 to move up and down. The extension assembly is located on... On the lifting plate 59, the side plate 51 improves the stability and reliability of the support frame 54 installation. The first roller 52 is rotated by the sixth motor 53, which can make the conveying mechanism 15 move along the third slide rail 50 to convey the fixed cover plate. The telescopic rod 60 improves the stability and reliability of the movement of the lifting plate 59, avoids the lifting plate 59 from tilting and affecting the movement accuracy of the extension component, and ensures that the fixed cover plate can be conveyed normally. The hoisting component can drive the lifting plate 59 to move up and down, and then drive the fixed cover plate to move through the extension component. The extension component makes it easy to clamp the fixed cover plate.

[0062] The hoisting assembly includes a winding machine 55, a pull rope 56, a guide wheel 57, and a lifting lug 61. The winding machine 55 is mounted on a support frame 54. The guide wheel 57 is connected to the support frame 54 via a suspension block 58. The lifting lug 61 is located on the top surface of the lifting plate 59. The winding machine 55 connects to the lifting lug 61 via the pull rope 56, which passes around the guide wheel 57. The winding machine 55 drives the pull rope 56 to move, which in turn drives the lifting plate 59 to move via the lifting lug 61. The suspension block 58 improves the stability and reliability of the guide wheel 57 installation. The guide wheel 57 helps improve the stability of the pull rope 56 movement. The winding machine 55 can use a motor and a winding wheel. The winding wheel is connected to the pull rope 56, which facilitates the control of the lifting plate 59 rising or falling.

[0063] The expansion assembly includes an air pump 63, an air supply pipe 64, and a fixed pipe 62. The air pump 63 and the fixed pipe 62 are respectively located on the upper and lower sides of the lifting plate 59. The air pump 63 is connected to the fixed pipe 62 through the air supply pipe 64. Second cylinders 67 are evenly arranged on the outer circumferential side of the fixed pipe 62. The second cylinders 67 are equipped with support rods 68 and are connected to a diverter pipe 66. The diverter pipe 66 is connected to the air supply pipe 64 through a guide pipe 65. The air pump 63 can control the operation of the second cylinders 67 through the air supply pipe 64, thereby controlling the extension or retraction of the support rods 68 to meet the requirements of conveying the fixed cover plate. The air supply pipe 64 can divert the gas through the diverter pipe 66 via the guide pipe 65 to control the movement of each support rod 68. When the fixed pipe 62 is inserted into the first through hole 3 of the fixed cover plate, the support rods 68 can extend a short distance to contact the annular surface 5. Multiple support rods 68 contacting the annular surface 5 can realize the conveying of the fixed cover plate, which is flexible and convenient to use.

[0064] b. Then, the fixed cover plate is lowered onto the rotating mechanism 14 via the conveying mechanism 15 through the extension component, so that the positioning ring 4 on the fixed cover plate is fitted onto the support sleeve 18 of the rotating mechanism 14, and the support sleeve 18 presses against the annular surface 5 between the first through hole 3 and the positioning ring 4.

[0065] c. Next, observe the position of the mounting block 2 on the fixed cover plate through the window on the cabinet door 12 or the visual sensor inside the second box 11. Control the rotation mechanism 14 to rotate through the control panel 13 on the cabinet door 12, so that the mounting block 2 is respectively limited to each clamping component 19 on the rotation mechanism 14.

[0066] The rotating mechanism 14 includes a turntable 17 and a first motor 22. A rotating shaft 20 is provided on the bottom surface of the turntable 17, and the rotating shaft 20 vertically penetrates the top surface of the first housing 10. An external gear ring 21 is provided at the bottom of the rotating shaft 20. The first motor 22 is located inside the first housing 10. The output shaft of the first motor 22 is connected to a drive gear 23, which meshes with the external gear ring 21. A support sleeve 18 and a clamping assembly 19 are provided on the top surface of the turntable 17. The support sleeve 18 is located at the center of the turntable 17, and the clamping assembly 19 is distributed in a ring on the turntable 17. The first motor 22 drives the external gear ring 21 to rotate via the drive gear 23, which in turn drives the turntable 17 to rotate via the rotating shaft 20, thereby adjusting the fixed cover plate to meet the drilling requirements at different positions. The support sleeve 18 is used to position and support the fixed cover plate, and the clamping assembly 19 is used to clamp the mounting block 2, improving the stability and reliability of the fixed cover plate during drilling.

[0067] The clamping assembly 19 includes a first slide rail 26, a second motor 27, a first screw 29, a clamping block 30, and a first stop 28. The second motor 27 and the first stop 28 are mounted on the turntable 17. The second motor 27 is connected to the first stop 28 via the first screw 29. The first screw 29 has two threaded sections with opposite rotation directions. The two first slide rails 26 are parallel to each other on the turntable 17 and are located on both sides of the first screw 29. The clamping block 30 is movably connected to the first slide rail 26 and has a groove 34. The groove 34 is connected to the first slide rail 26. The first slide rail 26 is matched, and the bottom surface of the clamping block 30 is provided with a first push block 33. The first push block 33 is located on the first screw 29. The clamping block 30 is provided with an anti-slip strip 32. The first screw 29 is rotated by the second motor 27, and the clamping block 30 can be moved along the second slide rail 35 by the first push block 33 to achieve the clamping requirements of the fixed cover plate. The anti-slip strip 32 can improve the stability and reliability of clamping the mounting block 2 and avoid slippage during drilling, which would affect the processing accuracy and quality of the fixed cover plate.

[0068] Support blocks 24 are evenly distributed in a ring on the bottom surface of the turntable 17. The support blocks 24 are equipped with second rollers 25. The second rollers 25 are supported on the top surface of the first housing 10. The design of the support blocks 24 and the second rollers 25 not only helps to improve the stability and reliability of the turntable 17 when it rotates, but also provides support when drilling holes in the fixed cover plate to prevent the turntable 17 from tilting.

[0069] The thickness of the support sleeve 18 is less than the width of the annular surface 5, which is beneficial for the expansion component to support the fixed cover plate and meet the requirements for conveying the fixed cover plate.

[0070] 3) Fixing the cover plate

[0071] a. After the mounting block 2 corresponds with the clamping assembly 19, start each clamping assembly 19 to clamp the mounting block 2.

[0072] b. Then retract the extension assembly to detach it from the fixed cover plate, and raise the extension assembly above the drilling mechanism 16 via the conveying mechanism 15.

[0073] 4) Drill holes for fixing the cover plate

[0074] a. After the conveying component is moved into place, the drilling mechanism 16 is started to drill holes in the fixed cover plate. The drilling mechanism 16 includes an X-axis moving component, a Y-axis moving component and a drilling component. The X-axis moving component is located on the inner wall of the second housing 11, the Y-axis moving component is located between the two X-axis moving components, and the drilling component is located on the Y-axis moving component. The drilling component is moved by the X-axis moving component and the Y-axis moving component, thereby meeting the drilling requirements at different positions on the fixed cover plate.

[0075] The X-axis moving assembly includes a second slide rail, a second stop 36, a guide rail 37, a third motor 38, and a second screw 39. The two second slide rails are distributed parallel to each other on the inner wall of the second housing. Two second stops 36 are provided on one side of the second slide rail, and a guide rail 37 is provided between the two second stops 36. The second slide rail on the other side is provided with a second stop 36 and a third motor 38. The third motor 38 is connected to the second stop 36 through the second screw 39.

[0076] The Y-axis moving assembly includes a second pusher block 40, a fourth motor 41, a third stop block 42, a guide rod 43, and a third screw 44. The two second pusher blocks 40 are respectively movably connected to the second screws 39, the guide rail 37, and the second slide rail on both sides.

After one hole is completed, lift the drilling mechanism 16, start the rotating mechanism 14, and drive the fixed cover plate to rotate to the next processing position to process another hole until the mounting hole 6, the second through hole 8 and the third through hole 9 on the fixed cover plate are completed.

[0079] 5) Fixed cover plate output feeding

[0080] a. The drilling mechanism 16 moves to the side close to the back plate of the second housing 11, starts the conveying mechanism 15, lowers the extension component into the first through hole 3 on the fixed cover plate, opens the extension component, and at the same time releases the clamping component 19.

[0081] b. Then, start the conveying mechanism 15 to lift the fixed cover to the set position and convey it to the cabinet door 12. Replace the next fixed cover with an external robot arm.

[0082] 6) Polishing

[0083] The fixed cover plate after processing is polished using a grinding machine.

[0084] The manufacturing method is simple and not only facilitates the automatic loading and unloading of the fixed cover plate, but also improves the processing efficiency of the fixed cover plate, increases processing accuracy, and reduces the scrap rate.
