Description

Technical Field

[0001] This invention relates to the field of automobile manufacturing technology, and in particular to an automobile door hinge bushing pin pressing device. Background Technology

[0002] The car door hinge is a core mechanical component connecting the car door to the car body. It is responsible for enabling smooth opening and closing, precise positioning, and safe support of the door. The car door hinge mainly consists of a body panel, a door panel, a hinge pin, and a bushing. The door panel is fixed to the side of the door, while the body panel is fixed to the car body by bolts or welding. The hinge pin connects the door panel and the body panel, enabling the door to rotate. The bushing is installed between the hinge pin and the pin hole and is usually made of wear-resistant material to make opening and closing the door smoother, quieter, and more durable.

[0003] When installing the pin and bushing, a special press or guide tool is required to press the hinge pin in from top to bottom or from front to back (depending on the hinge structure). The pin and bushing inner hole have an interference fit (tight fit) and will not fall off by themselves after being pressed in. However, the insertion of the pin and bushing is mainly done manually. The pressing process is semi-automatic or manual, and manual straightening is required during pressing, which greatly reduces work efficiency.

[0004] In view of this, the present invention provides an automotive door hinge bushing pin pressing device to solve the technical problems existing in the prior art. Summary of the Invention

Continuous pressure is applied to complete the pressing of the bushing and pin. Afterward, the pressing mechanism retracts and resets, and the body panel positioning assembly and door panel positioning assembly retract synchronously, releasing the intercepted door hinge. The unloading conveyor belt is used to collect the door hinges after pressing. Attached Figure Description

Detailed Implementation

[0019] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] Reference Figures 1-13A device for pressing in automotive door hinge bushing pins includes a device bracket 1. A worktable 2 is fixedly installed at the top center of the device bracket 1, and a material discharge hole is provided at the top of the worktable 2. A pressing station is provided above the material discharge hole. Feeding conveyor belts 3 are fixedly installed on both sides of the top of the device bracket 1, and two feeding guide mechanisms 4 arranged in a J-shape are installed at the ends of the two feeding conveyor belts 3. The bottom of the two feeding guide mechanisms 4 is respectively installed on both sides of the material discharge hole. The two feeding guide mechanisms 4 feed according to the outer dimensions of the body panel 9 and the door panel 10. In this design, the body panel 9 and door panel 10 are placed on the feeding conveyor belt 3. The feeding conveyor belt 3 pushes the body panel 9 and door panel 10 sequentially into two feeding guide mechanisms 4, where they move downwards under gravity. A hinge positioning mechanism 5 is installed on the top of the workbench 2. The hinge positioning mechanism 5 consists of a body panel positioning component 51 and a door panel positioning component 52. The ends of the body panel positioning component 51 and the door panel positioning component 52 are respectively embedded inside the feeding guide mechanism 4 to intercept the body panel 9 and door panel 10 falling from the feeding guide mechanism 4 and to keep the body panel 9 and door panel 10 in place. The door leaf 10 is clamped and fixed at the pressing station of the pin 11 and bushing 12. Symmetrically distributed pneumatic feeding mechanisms 6 are installed at both ends of the top of the workbench 2. The discharge ends of the two pneumatic feeding mechanisms 6 are inserted into the gap between the two feeding guide mechanisms 4. The other ends of the two pneumatic feeding mechanisms 6 are respectively equipped with stepped discharge hoppers for conveying the pin 11 and bushing 12. The pneumatic feeding mechanisms 6 are horizontally arranged, and a pressing mechanism 7 is fixedly installed at the tail end of each pneumatic feeding mechanism 6. Under the action of the pneumatic feeding mechanisms 6, the pin 11 and bushing 12 are horizontally distributed on both sides of the pressing station. 9. After the door panel 10 is positioned, the pressing mechanism 7 on one side pushes the pin 11 into the hinge hole of the door panel 10, and the pressing mechanism 7 on the other side then pushes the bushing 12 into the hinge hole of the body panel 9. When the bushing 12 is pushed in, it fits in the pressing end of the pin 11. Continuous pressure is applied to press the bushing 12 and the pin 11 together. After that, the pressing mechanism 7 retracts and resets, and the body panel positioning component 51 and the door panel positioning component 52 retract synchronously to loosen the intercepted door hinge. The bottom of the equipment bracket 1 is equipped with a feeding conveyor belt 8, which is used to collect the door hinges after pressing.

[0021] The feeding guide mechanism 4 includes a vertically distributed feeding section 41 and a horizontally arranged inlet section 42. The front end of the inlet section 42 is provided with a V-shaped guide groove 43. The outer sides of the feeding section 41 and the inlet section 42 are provided with limiting grooves connected to the guide groove 43. A material distribution component is provided below the feeding section 41. The feeding guide mechanism 4 is designed according to the dimensions of the body panel 9 and the door panel 10. The body panel 9 and the door panel 10 enter the inlet section 42 through the guide groove 43 and are stacked in the feeding section 41 under the action of gravity. The hinge holes of the body panel 9 and the door panel 10 are inserted into the limiting grooves. The installation parts of the body panel 9 and the door panel 10 that are connected to the body and the door are constrained in the material groove of the feeding section 41, thus completing the conveying and feeding operation of the body panel 9 and the door panel 10. The material distribution assembly includes a material distribution housing 44 installed on the feeding section 41. Mounting slots are provided on both sides of the material distribution housing 44. Movable latches 45 are spring-loaded inside the mounting slots. A distribution roller 47 is rotatably mounted inside the material distribution housing 44. A motor 46, which drives the distribution roller 47, is mounted on the outside of the material distribution housing 44. A pusher bolt 48 is screwed onto the outside of the distribution roller 47. The material distribution assembly is designed based on the vehicle body page 9 and the door page 10. When the vehicle body page 9 and the door page 10 fall, they are stopped by the movable latches 45. The motor 46 and the distribution roller 47 drive the pusher bolt 48 to rotate. When the pusher bolt 48 rotates, its outer end is inserted into the mounting holes of the vehicle body page 9 and the door page 10. The vehicle body page 9 and the door page 10 overcome the pressure of the movable latches 45 and move downwards, where they are clamped and fixed by the vehicle body page positioning assembly 51 and the door page positioning assembly 52, thus completing the automatic feeding operation of the vehicle body page 9 and the door page 10. The body panel positioning assembly 51 includes a body panel positioning cylinder 511 mounted on the top of the workbench 2 and a body panel fixing mold 513 inserted into the body panel feeding guide mechanism 4. A spring rod 515 is fixedly mounted on the outer side of the body panel fixing mold 513, and a right push block 514 is installed between the spring rod 515 and the body panel positioning cylinder 511. A push guide cover 512 is sleeved on the outer side of the right push block 514. The body panel fixing mold 513 is embedded into the body panel feeding guide mechanism 4 under the thrust of the spring rod 515. When the body panel 9 falls, it is inserted into the body panel fixing mold 513. When the pin 11 and bushing 12 are installed, the door panel positioning assembly 52 moves towards the body panel 9. The body panel positioning assembly 51 and the door panel positioning assembly 52 clamp and fix the body panel 9 and the door panel 10, avoiding misalignment or offset during the installation of the pin 11 and bushing 12, and improving the efficiency of door hinge assembly. The door panel positioning assembly 52 includes a door panel positioning cylinder 521 mounted on the top of the worktable 2 and a door panel fixing mold 525 inserted into the door panel feeding guide mechanism 4. The door panel positioning assembly 52 also includes a track 522 mounted on the top of the worktable 2. An L-shaped clamping member 523 is slidably mounted on the upper end of the track 522. The tail end of the clamping member 523 is fixedly connected to the door panel positioning cylinder 521. A horizontal shaft 524 is fixedly mounted above the clamping member 523. The bottom of the door panel fixing mold 525 has a circular hole that slides with the horizontal shaft 524. A push spring is installed between the door panel fixing mold 525 and the clamping member 523. Two door panel positioning pins 526 that mate with the mounting holes of the door panel 10 are mounted on the top of the clamping member 523. The door panel fixing mold 525 is embedded into the interior of the door panel feeding guide mechanism 4 under the thrust of the push spring. When the door panel 10 falls... After the door panel is inserted into the door panel fixing mold 525, the door panel positioning cylinder 521 pushes the clamping member 523 to move towards the door panel 10. The front end of the clamping member 523 clamps and cooperates with the body panel fixing mold 513 to position and fix the body panel 9. At the same time, the door panel positioning pin 526 is inserted into the mounting hole of the door panel 10 to complete the positioning and fixing operation of the door panel 10. At this time, the hinge holes of the body panel 9 and the door panel 10 are located on the same axis, completing the automatic positioning and fixing operation of the door hinge, improving the assembly efficiency of the door hinge, and avoiding vibration during the installation of the pin 11 and bushing 12, thus improving the assembly stability of the door hinge. After the door hinge is assembled, the body panel positioning component 51 and the door panel positioning component 52 retract, and push the body panel fixing mold 513 and the door panel fixing mold 525 backward to separate from the feeding guide mechanism 4, and release the assembled door hinge for unloading. The clamping member 523 has a positioning groove 527 at its front end, and a positioning sensor 528 is installed inside the positioning groove 527. The positioning sensor 528 is a pressure sensor. A horizontally positioned positioning rod 516 is installed on the side of the right push block 514, and a through groove is provided on the surface of the body page fixing mold 513 to slide with the positioning rod 516. The positioning rod 516 is inserted and pulled into the positioning groove 527. When the clamping member 523 moves to the rightmost position, the body page positioning cylinder 511 drives the right push block 514 to move continuously, so that the positioning rod 516 passes through the mounting hole of the body page 9 and inserts into the positioning groove 527, and squeezes the positioning sensor 528 to generate a signal, confirming that the body page positioning assembly 51 and the door page positioning assembly 52 have completed the mold closing and squeeze and fix the body page 9 and the door page 10, ensuring that the hinge holes of the body page 9 and the door page 10 are accurately aligned. The pneumatic feeding mechanism 6 includes a horizontal guide tube 61 fixedly installed on the workbench 2, and a guide tube 62 obliquely inserted above the horizontal guide tube 61. A rectangular through-slot 63 is provided on the outer side of the guide tube 62, and a discharge assembly is fixedly installed on the outer side of the rectangular through-slot 63. A suction hole 64 is provided at the bottom of the horizontal guide tube 61. The other ends of the two pneumatic feeding mechanisms 6 are respectively equipped with stepped discharge hoppers. Taking the pin 11 as an example, the pin 11 is inserted downwards with its insertion end facing down under the action of the stepped discharge hopper. In the guide tube 62, the material enters the horizontal guide tube 61 under the conveying of the guide tube 62. At this time, the pin 11 is placed horizontally in the horizontal guide tube 61. When the outlet of the horizontal guide tube 61 and the hinge hole of the door hinge are on the same axis, the pressing mechanism 7 pushes the pin 11 out of the horizontal guide tube 61, and the pin 11 can be inserted into the hinge hole. The bushing 12 is inserted into the hinge hole on the other side through the same steps, completing the assembly and feeding operation of the pin 11 and the bushing 12, and improving the hinge assembly efficiency. The discharge assembly includes a discharge housing 65, and discharge conveyor belts 66 are installed on both sides of the discharge housing 65 via rollers and motors. The two discharge conveyor belts 66 are distributed in a V-shape. Multiple U-shaped push plates are provided on the outer side of the discharge conveyor belts 66. A counting sensor 67 is installed at the bottom of the discharge housing 65. Taking the pin 11 as an example, when the pin 11 falls into the discharge assembly area, it is intercepted by the push plates distributed in a V-shape on both sides. When feeding is required, the discharge conveyor belt 66 rotates and pushes the pins 11 one by one into the horizontal guide tube 61. The bushing 12 is conveyed to another horizontal guide tube 61 through the same steps, thus accurately dispensing the materials. The pressing mechanism 7 includes a pressing cylinder 71 fixedly installed on the workbench 2 and a guide nozzle 73 screwed to the outlet of the horizontal guide tube 61. The output end of the pressing cylinder 71 is equipped with a pressing die 72, and the pressing die 72 is inserted into the interior of the horizontal guide tube 61. When the body panel 9 and the door panel 10 are fixed at both sides of the pressing station, the guide nozzle 73 and the hinge holes on the body panel 9 and the door panel 10 are arranged on the same axis. The pin 11 and the bushing 12 are inserted from both ends of the hinge hole and are fixed by interference fit under pressure. The automated pressing operation improves the efficiency of door hinge assembly. The crimping mechanism 7 also includes a shaft alignment assembly embedded inside the guide nozzle 73. The shaft alignment assembly includes a retaining ring 74 and multiple elastic elements 75 arranged in a ring array inside the retaining ring 74. A shaft alignment ball head 76 is installed on the outer side of the elastic element 75. When the pin 11 and bushing 12 are pushed into the guide nozzle 73, the ring array of shaft alignment ball heads 76 simultaneously presses the outer wall of the pin 11 and bushing 12, lifting their outer ends to a horizontal state, so that they are aligned with the hinge holes on the body panel 9 and door panel 10. The pin 11 and bushing 12 are directly inserted into the hinge holes, avoiding misalignment, improving the stability of the pin 11 and bushing 12 insertion process, and further improving the efficiency of door hinge assembly.

[0022] In use, the two feeding guide mechanisms 4 are designed according to the external dimensions of the body panel 9 and the door panel 10, respectively. The body panel 9 and the door panel 10 are placed on the feeding conveyor belt 3, and the feeding conveyor belt 3 pushes the body panel 9 and the door panel 10 into the two feeding guide mechanisms 4 in sequence. Under the action of gravity, they are stacked in the feeding section 41. When the body panel 9 and the door panel 10 fall, they are stopped by the movable buckle 45, and the motor 46 and the distribution roller 47 drive the push bolt 48 to rotate. When the push bolt 48 rotates, its outer end is inserted into the mounting hole of the body panel 9 and the door panel 10. The body panel 9 and the door panel 10 move downward against the pressure of the movable buckle 45 and are clamped and fixed by the body panel positioning component 51 and the door panel positioning component 52. The other end of the two feeding guide mechanisms 4 is respectively equipped with a stepped discharge hopper. The pneumatic feeding mechanism 6 is used to convey the pin 11 and bushing 12. It is horizontally set and the tail end of the pneumatic feeding mechanism 6 is fixedly installed with the pressing mechanism 7. Under the action of the pneumatic feeding mechanism 6, the pin 11 and bushing 12 are horizontally distributed on both sides of the pressing station. After the body panel 9 and door panel 10 are positioned, the pressing mechanism 7 on one side pushes the pin 11 into the hinge hole of the door panel 10. The pressing mechanism 7 on the other side then pushes the bushing 12 into the hinge hole of the body panel 9. When the bushing 12 is pushed in, it fits in the pressing end of the pin 11. Continuous pressure is applied to press the bushing 12 and the pin 11 together. After that, the pressing mechanism 7 retracts and resets, and the body panel positioning component 51 and the door panel positioning component 52 retract synchronously to loosen the intercepted door hinge. The unloading conveyor belt 8 is used to collect the door hinge after pressing.
