Description

Technical Field

[0001] The present invention relates to the technical field of vehicle axle assembly, and in particular to an automatic vehicle axle assembly device and an assembly method. Background Art

[0002] The axle is a bridge structure that is connected to the frame through the suspension and has car wheels installed at both ends. It is the main component of the car's running system. The function of the axle is to transmit the forces and torques in all directions between the frame and the wheels. It has an important influence on the car's dynamics, stability, carrying capacity and other performances. The car body is composed of a car body and multiple small parts.

[0003] The car body needs the assistance of multiple workers to clean and assemble, so the assembly efficiency is low. Since the car body is large and has a large number of small parts, it is generally placed in a large cleaning tank for cleaning. The cleaning fluid in the cleaning tank is contaminated after the first cleaning, which causes the car body and small parts to be cleaned subsequently. The impurities in the cleaning fluid contaminate the car body and small parts, resulting in the surface of the car body and small parts cannot be completely cleaned, affecting the subsequent assembly quality. During the assembly process, due to the shape of the car body, it is necessary to manually flip the car body to ensure smooth assembly with the parts to be assembled, which increases the difficulty of the workers' work and affects the assembly efficiency.

[0020] The present invention has the following beneficial effects: 1. An automatic assembly equipment and method for an axle provided by the present invention cleans the car shell and small parts through a cleaning unit and dries them. During the whole cleaning process, impurities in the cleaning liquid are precipitated under the action of gravity and are in a different space from the upper cleaning liquid. The inclined liquid containing the precipitate is filtered to ensure the separation of the precipitate and the cleaning liquid, and the cleanliness of the cleaning liquid used to clean the car shell and small parts. Impurities in the cleaning liquid are prevented from adhering to the surface of the car shell and small parts again to cause pollution, thereby affecting the subsequent assembly quality. The car shell and small parts are transported through an assembly table and assembled by a mechanical arm. The car shell is flipped through the assembly table to be assembled smoothly. No workers are required to assist in the whole process, thereby improving the efficiency of axle assembly.

[0021] 2. The cleaning unit provided in the present invention sprays inclined liquid onto the surface of the car body and small parts in the transport cylinder 1 and the transport cylinder 2 through the liquid spray port, thereby accelerating the cleaning speed, allowing impurities generated during the cleaning process to fall smoothly to the bottom of the box through the cylindrical through hole, and preventing impurities entering the bottom of the box from flowing back to the upper side of the rectangular flat plate with the liquid through the spiral tube.

[0022] 3. The cleaning unit provided in the present invention drives the annular gear to rotate through the cylindrical gear, and finally causes the cylindrical barrel 1 and the spiral column 1 to rotate toward each other, thereby slowing down the transportation speed of the car shell and ensuring that it is cleaned enough in the cleaning box. The cleaning liquid can smoothly enter the cylindrical barrel 1 through the liquid inlet hole 1 in cooperation with the arc grid plate.

[0023] 4. The assembly table provided in the present invention drives the rotating cross plate to rotate through the motor four, thereby controlling the car shell on the rotating cross plate to flip, and the car shell is positioned during the flipping process by cooperating with the air pump and the rubber suction cup to prevent it from falling off. When the processing is completed, the rotating cross plate continues to rotate, and the rubber suction cup is no longer attracted to the car shell. Under the action of gravity, the car shell moves to the right with the rotating cross plate and falls onto the transport platform three. BRIEF DESCRIPTION OF THE DRAWINGS
