Description

Technical Field

[0001] This utility model relates to the field of assembly equipment, specifically to a door mounting assist arm. Background Technology

[0002] When assembling car doors on an automobile production line, the car body is typically moved to the designated installation position, then a robotic arm is used to hold the door in place, and finally, the robotic arm is pushed to the door frame for installation. By incorporating robotic arms during automobile manufacturing, the labor intensity of workers is reduced, and work efficiency is improved. Car doors are generally mounted on the car body using hinges. The function of the hinges is to support the door, ensuring it is securely attached to the car body and allowing it to move. Hinges are commonly known as door hinges or door hinges. Currently, there are two common types: stamped hinges and cast hinges. Due to differences in structural design, the material thickness of the two types of hinges also differs. Cast hinges are often much thicker than stamped hinges, and they are widely used due to their higher production precision and uniformity.

[0003] Existing power-assisted robotic arms can only clamp and fix car doors. Moreover, the existing power-assisted robotic arms have a complex structure, require manual loading during installation, and do not have the ability to automatically grasp car doors, resulting in high labor intensity for workers. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this utility model provides a door mounting assist arm that is simple in structure, easy to operate, and labor-saving.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A door mounting assist arm, characterized in that it includes a boom and a gripping clamp, the gripping clamp being connected to the lower end of the boom, the upper end of the boom having a connecting flange, the gripping clamp including a suction cup gripping unit and a support positioning unit, the suction cup gripping unit being slidably disposed on the upper part of the support positioning unit, the lower part of the support positioning unit having a crossbeam, the crossbeam having two support frames with adjustable spacing, the support frames having limit blocks, the support positioning unit having a first side support block in the middle, the support positioning unit having a second side support block at the upper part, the suction cup gripping unit having two vacuum suction cups, and the support positioning unit having an operating lever.

[0007] Furthermore, the support positioning unit has a vertically arranged linear guide slider assembly, the suction cup gripping unit is disposed on the linear guide slider assembly, and the support positioning unit is provided with a lifting cylinder, which drives the suction cup gripping unit to rise and fall.

[0008] Furthermore, the rear of the support and positioning unit is provided with a bracket for placing an electric wrench and a box for placing bolts.

[0009] Furthermore, a swing pitch mechanism is provided between the boom and the support positioning unit. The swing pitch mechanism includes a pitch cylinder located at the lower end of the boom. The piston rod of the pitch cylinder is connected to a rocker arm. The rocker arm is connected to a rotating block on the support positioning unit via a rotating shaft. A swing cylinder is provided on the support positioning unit. The swing cylinder is connected to the rotating block via a swing arm.

[0010] Furthermore, a controller is provided on the control lever.

[0011] The advantages of this utility model include: simple structure, convenient operation, automatic door grabbing, high flexibility, saving manpower, improving assembly efficiency, and convenient tool placement. Attached Figure Description

[0014] Figure 3 yes Figure 2 A magnified view of a portion of the image. Detailed Implementation

[0015] The present invention will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0016] One such Figure 1-3 The door mounting assist arm shown includes a boom 1 and a gripping clamp. The gripping clamp is connected to the lower end of the boom 1, and the upper end of the boom 1 has a connecting flange for connecting to the suspension and translation mechanism. The gripping clamp includes a suction cup gripping unit and a support positioning unit. The suction cup gripping unit is slidably mounted on the upper part of the support positioning unit. The lower part of the support positioning unit has a crossbeam 2, and two support frames 3 are adjustable in spacing on the crossbeam 2. The support frames 3 are perpendicular to the support positioning unit, and limit blocks 4 are provided on the support frames 3 to limit the bottom edge of the door. The support positioning unit has a first side support block 5 in the middle and a second side support block 6 on the upper part of the support positioning unit. The first side support block 5 and the second side support block 6 are used to support the sides of the door. The suction cup gripping unit has two vacuum suction cups 7, and the support and positioning unit has a vertically arranged linear guide slider assembly 9. The suction cup gripping unit is mounted on the linear guide slider assembly 9, and the support and positioning unit is equipped with a lifting cylinder 10, which drives the suction cup gripping unit to rise and fall. Therefore, when gripping a car door, the vacuum suction cups 7 pick up the car door, and then the lifting cylinder 10 lifts the car door, so that the lower end of the car door is limited on the support frame 3.

[0017] An operating lever 8 is located behind the support positioning unit, and a controller 16 is mounted on the operating lever 8. Workers can grasp the operating lever 8 to move the resistance arm, thus moving the car door onto the assembly line for assembly.

[0018] For ease of assembly, the rear of the support and positioning unit is provided with a bracket 11 for holding an electric wrench and a box 17 for holding bolts.

[0019] To further improve the flexibility of the resistance arm, a swing-tilt mechanism is provided between the boom 1 and the support positioning unit in this embodiment. The swing-tilt mechanism includes a tilt cylinder 12 located at the lower end of the boom 1. The piston rod of the tilt cylinder 12 is connected to a rocker arm 13. The rocker arm 13 is connected to a rotating block 14 on the support positioning unit via a rotating shaft. A swing cylinder 15 is provided on the support positioning unit. The swing cylinder 15 is connected to the rotating block 14 via a swing arm 15. Buffer devices are provided on both sides of the rocker arm 13 and the swing arm 15, which makes the resistance arm more stable and avoids the vibration of the door caused by rigid impact.
