Description

Technical Field

[0001] The present application relates to the field of automobile component processing, and in particular to a door hinge clamp. Background Art

[0002] Gull-wing doors are a way of opening the doors of super sports cars. Gull-wing doors have a dynamic appearance and give people a feeling of flapping wings. Gull-wing doors are named because they open upwards and resemble the wings of a seagull. Door hinges are a mechanical device that connects two objects and allows them to rotate relative to each other, and are the core components that enable gull-wing doors to rotate on the car body.

[0003] In order to make the opening and closing of the gull-wing door smoother, the existing gull-wing door hinges are usually manufactured into a special shape. However, the existing clamps cannot support the door hinges with height differences. Without bottom support, drilling can easily cause the door hinges to deviate due to lack of bottom support, thereby affecting the drilling accuracy of the door hinges. Utility Model Content

[0016] Optionally, a support platform is provided between the mounting platform and the placing platform, and an insertion rod is provided on the support platform.

[0017] By adopting the above technical solution, the support platform is used to support the portion of the door hinge that does not need to be processed, thereby reducing the probability that the portion of the door hinge that does not need to be processed is deflected by gravity.

[0018] Optionally, a lifting rod is arranged directly above the support platform, and the lifting rod slides toward or away from the support platform.

[0019] By adopting the above technical solution, the setting of the lifting rod can cooperate with the support platform to clamp the part of the door hinge that does not need to be processed.

The door hinge 0 in this embodiment includes a horizontal portion 01 and a stepped portion 02 integrally formed on the horizontal portion 01. The door hinge 0 fixture includes a rectangular table 1 for installation on a drilling device. A mounting table 2 is detachably installed on the upper surface of the table 1 near one end in the length direction. The height of one end of the mounting table 2 in the length direction is higher than that of the other end in the length direction to form a stepped table. A positioning block 3 is fixedly provided on one side wall of the mounting table 2 near the end with a higher height in the length direction. A sliding block 4 is slidably provided on the other side wall of the mounting table 2 near the end with a higher height in the length direction. The sliding block 4 slides toward or away from the positioning block 3, and the horizontal portion 01 of the door hinge 0 is placed between the positioning block 3 and the sliding block 4 of the mounting table 2. At the same time, the stepped portion 02 of the door hinge 0 is placed at a lower height of the mounting table 2. The horizontal portion 01 of the door hinge 0 is clamped by the positioning block 3 and the sliding block 4, so that subsequent drilling of the horizontal portion 01 of the door hinge 0 is convenient.

[0033] Reference Figure 1 and Figure 2 A limiting platform 5 is provided at one end of the mounting platform 2 in the length direction away from the positioning block 3. The limiting platform 5 is used to abut against one end of the door hinge 0 in the length direction to limit the door hinge 0 in the length direction. A top block platform 6 is installed on the mounting platform 2 on the side of the limiting platform 5 facing the positioning block 3. A lower top block 7 is hingedly provided on the top block platform 6. One end of the lower top block 7 in the length direction abuts against the bottom of the door hinge 0. A driving screw 8 is threadedly connected to the top block platform 6. The driving screw 8 abuts against one end of the lower top block 7 in the length direction away from the door hinge 0. The driving screw 8 is rotated to make the driving screw 8 slides toward the lower top block 7, the driving screw 8 drives the lower top block 7 to slide along the height direction of the mounting platform 2 toward the door hinge 0, a pressure rod platform 9 is installed on the limit platform 5, and an upper pressure rod 10 is threadedly connected to the pressure rod platform 9, and the upper pressure rod 10 is located directly above the lower top block 7. The upper pressure rod 10 is rotated to drive the upper pressure rod 10 to slide toward or away from the lower top block 7, and the step portion 02 of the door hinge 0 is clamped by the upper pressure rod 10 and the lower top block 7, thereby reducing the probability of the step portion 02 being lifted due to force when drilling the horizontal portion 01 of the door hinge 0.

[0034] Reference Figure 1 and Figure 2A drilling groove 11 is provided on the mounting table 2 between the positioning block 3 and the sliding block 4. In the present embodiment, two drilling grooves 11 are provided. The provision of the drilling groove 11 can reduce the probability of the rotary head hitting the mounting table 2 after penetrating the door hinge 0, thereby reducing the probability of the drill bit being damaged due to hitting the mounting table 2; a chip removal hole 12 is provided on one side of the positioning block 3 in the width direction of the mounting table 2, the chip removal hole 12 is connected to the bottom of the drilling groove 11, and the chip removal hole 12 is inclined toward the table plate 1. The provision of the chip removal hole 12 can facilitate the removal of debris that falls into the drilling groove 11, thereby reducing the probability of the chip removal hole 12 being blocked by debris.

[0035] Reference Figure 1 and Figure 2 A sliding block 4 is provided in the width direction of the mounting platform 2, and a driving platform 13 is provided on one side. The driving platform 13 can be detachably mounted on the table plate 1. A driving member 14 is rotatably provided on the driving platform 13. In this embodiment, the driving member 14 uses a cam, and the cam abuts against the end of the sliding block 4 away from the positioning block 3. The sliding block 4 is driven to slide toward the positioning block 3 by rotating the cam. A spring 15 is provided between the sliding block 4 and the mounting platform 2. The spring 15 drives the sliding block 4 to slide away from the positioning block 3. The sliding block 4 is driven to slide by rotating the cam to clamp the door hinge 0. At the same time, the sliding of the sliding block 4 can also be limited by abutment. A guide rod 16 is horizontally arranged on the mounting platform 2, and the guide rod 16 passes through the sliding block 4. The guide rod 16 is used to guide the sliding of the sliding block 4. The spring 15 is sleeved on the guide rod 16, and the bending of the spring 15 is limited by the guide rod 16.

[0036] Reference Figure 1 and Figure 2A placing table 17 is detachably mounted on one side of the table 1 in the length direction away from the mounting table 2. A positioning table 18 is vertically fixed at one end in the width direction of the placing table 17. A positioning rod 19 is threadedly connected to the positioning table 18. The positioning rod 19 is adjusted by threaded connection to slide toward or away from the middle of the placing table 17. A cylinder table 20 is arranged at the other end in the width direction of the placing table 17. The cylinder table 20 is detachably mounted on the table 1. A cylinder is mounted on the cylinder table 20. A push rod 21 is mounted on the cylinder. The push rod 21 slides toward or away from the positioning rod 19. A lifting block 22 is arranged on the placing table 17. In this embodiment, two lifting blocks 22 are arranged. Lifting screws 23 are fixedly arranged on the two lifting blocks 22 facing the side of the placing table 17. The lifting screws 23 are threadedly connected to the placing table 17. When the lifting screws 23 are turned, the lifting screws 23 are lifted. The rod 23 drives the lifting block 22 to slide along the height direction of the placement table 17. A receiving groove 24 is provided on the lifting block 22 away from the placement table 17. A mounting plate 25 is vertically installed at one end of the placement table 17 away from the mounting table 2 in the length direction. A limit rod 26 is threadedly connected to the mounting plate 25. The limit rod 26 slides toward or away from the center of the placement table 17 by rotation. The positioning rod 19 can position one end of the door hinge 0 in the width direction when the door hinge 0 is placed on the placement table 17, and cooperates with the sliding push rod 21 to clamp the door hinge 0. Then, the lifting block 22 is driven to abut against the door hinge 0 to support the location where the door hinge 0 needs to be drilled. The receiving groove 24 can be used to store debris generated by drilling, and can also reduce the probability of the drill bit hitting the lifting block 22 during drilling, causing damage to the drill bit or the lifting block 22.

[0037] Reference Figure 1 and Figure 2 A support platform 27 is provided between the mounting platform 2 and the placing platform 17 on the table 1, and an insertion rod 28 is provided on the support platform 27.

The lifting rod 30 is arranged directly above the support platform 27. The lifting cylinder 29 drives the lifting rod 30 to slide toward or away from the support platform 27. The setting of the lifting rod 30 can clamp the door hinge 0 when the door hinge 0 is placed on the support platform 27, thereby reducing the probability of the door hinge 0 detaching from the support platform 27.

[0038] The implementation principle of the embodiment of the present application is as follows: the horizontal portion 01 of the door hinge 0 is placed on the mounting platform 2, and one end of the stepped portion 02 of the door hinge 0 is abutted against the limiting platform 5, so that the area of ​​the horizontal portion 01 that needs to be drilled is aligned with the drilling groove 11, and then the horizontal portion 01 of the door hinge 0 is clamped by driving the sliding block 4 to slide. After the horizontal portion 01 is clamped, the driving screw 8 is rotated to drive the lower top block 7 to abut the lower portion of the stepped portion 02 of the door hinge 0, and at the same time, the upper pressure rod 10 is rotated to abut the upper portion of the stepped portion 02, and then the horizontal portion 01 is drilled by the drilling equipment, and then the horizontal portion 01 is drilled. After the drilling of the horizontal part 01 is completed, the horizontal part 01 of the door hinge 0 is placed on the support platform 27, and the insertion rod 28 on the support platform 27 is inserted into the hole drilled on the horizontal part 01. Then, the lifting rod 30 is driven by the lifting cylinder 29 to be pressed on the horizontal part 01 to fix the horizontal part 01 of the door hinge 0. Subsequently, the positioning rod 19, the top rod 21 and the limit rod 26 are driven to abut against the circumference of the step part 02 of the door hinge 0 and the lifting block 22 is driven to abut against the bottom of the step part 02 of the door hinge 0. Then, the step part 02 is drilled by the drilling equipment to complete the drilling process of the door hinge 0.
