Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts assembly, in particular to a positioning and assembling device for automobile parts. Background Art

[0002] Auto parts are a general term for the various units that make up the entire car and the various units that serve the entire car. A car is made up of thousands of parts. These parts are manufactured according to specific design, materials, processes and technical requirements, and undergo strict inspection and quality control to ensure the performance, safety and reliability of the car. Auto parts include engine parts, chassis parts, body and accessories, electrical equipment and automotive electronic control devices. In the process of assembling the car door to the body, a positioning assembly device is needed to assist the door installation to facilitate the door installation.

[0003] After searching, the Chinese patent with application number CN202222486088.5 discloses an auxiliary positioning structure for a robotic arm to grasp automobile parts for assembly. There is a certain inertia for any mechanical movement, which makes it impossible to stop immediately after the bottom of the robotic arm rotates to the specified position. Without the help of a positioning mechanism, the deflection angle will gradually increase with the aging of the machine or long-term use. Therefore, the sliding plate and the limit plate can be fixed at the specified position by the engagement of the fixed gear sleeve and the fixed gear block of the fixing mechanism. The positioning block blocks the rotating mounting seat to avoid the rotation angle deviation due to inertia when the rotating mounting seat automatically assembles automobile parts through rotation, thereby causing the problem that the assembly connection of the automobile parts cannot be aligned and installed.

[0004] When positioning and assembling automobile parts as mentioned above, a robot arm is used for auxiliary positioning. However, the use cost of the robot arm is relatively high, which easily increases the cost of positioning and assembling automobile parts. Usually, when assisting the positioning of car doors among automobile parts, the car doors are manually held and then leaned against the car body. The car doors are held up by hand for a long time, which easily increases the fatigue of the operators, making the assembly of the car doors more difficult and prolonging the assembly time, resulting in reduced assembly efficiency of the car doors.
