Automatic assembling machine for automobile door hinge

Abstract

The invention belongs to the technical field of assembly of automobile components, and particularly relates to an automatic assembling machine for an automobile door hinge. The automatic assembling machine comprises an annular plate and a transmission rotation disk which is arranged in the middle of the annular plate and rotates intermittently; follow-up clamps with the number corresponding to that of processes are distributed on the surface of the plate; the transmission rotation disk is also provided with pushing mechanisms which are used for pushing the follow-up clamps to move along the surface of the transmission rotation disk in the radial direction; and a clamp positioning mechanism and a process execution mechanism are distributed on the surface of the annular plate; the pushing mechanism has two position states, wherein one of the positioning states is that the pushing mechanism pushes the clamp to extend out of the transmission rotation disk to reach the clamp positioning mechanism for positioning to ensure that the process execution mechanism can performing assembly of the process; and the other position state is that: after the process is finished, the clamp is driven to be contacted to the transmission rotation disk and is separated from the clamp positioning mechanism of the assembly position of the process. The automatic assembling machine has a simple structure, is easy to maintain and operate, greatly reduces the operation cost of hinge assembly manufacturers, and improves the running reliability of equipment.

Description

technical field [0001] The invention belongs to the technical field of assembly of automobile parts, and in particular relates to an automatic assembly machine for automobile door hinges. Background technique [0002] Automobile door hinge is a general term for the connection between the body and the door, which can rotate around the same axis in the up and down direction and combine with each other. According to the hinge manufacturing process, it can be roughly divided into stamping hinges and profile hinges. Among them, stamping hinges are widely used because of their simple form, good craftsmanship and low cost. The stamping hinge is generally composed of a main hinge, a secondary hinge, and a shaft sleeve and a shaft pin used to connect the two. It usually includes the processes of installing the shaft sleeve, threading the pin, rotating riveting, and measuring torsion. The previous stamping hinge assembly methods are all The above-mentioned parts are manually assemble...

Problems solved by technology

However, since the existing hinge assembly production line is arranged in a straight line, the manipulator transportation or the chain closed-loop transportation are used between each process, which often has the following defects: There are repeated positioning and complex processes, and the price is extremely expensive. However, if the chain closed-loop conveying is used, there will be elastic deformation of the closed-loop conveyor belt that will inevitably occur after long-term use. Once the closed-loop conveyor belt undergoes elastic deformation, accurate positioning cannot be
