The assembly and adjustment platform includes a top plate for installing mechanical components, which enables convenient and efficient installation and debugging. At the same time, it has power supply components inside to provide drive for the machinery.
[0003] The invention with publication number CN107363757A discloses a positioning mechanism for processing a tripod shaft fork of an automobile transmission system. The movable platform is pushed toward the fixed platform by the tripod shaft fork and the movable platform is driven to rotate by a power mechanism until the positioning block thereon is aligned with the shaft hole of the tripod shaft fork to complete the positioning.

[0004] The invention with publication number CN113752192A discloses a positioning mechanism for an assembly platform of a fully automatic backlight assembly machine. The preliminary positioning of the workpiece can be achieved by using the extrusion plate and the guide plate in the limit unit. Since the guide plate is inclined relative to the base, it is convenient to place the panel. When the workpiece is placed inside the installation platform, the extrusion plate is symmetrically arranged, and the elastic force of the spring a makes the workpiece located at the center of the installation platform, thereby achieving preliminary positioning of workpieces of different models.

Such positioning mechanisms are difficult to effectively adapt to different groups of mechanical parts. At the same time, the transmission-type mechanical parts vibrate during operation, and the assembly and adjustment platform cannot take into account stability while being easy to move, and is prone to resonance with the transmission machinery, affecting the normal operation of the assembly and adjustment platform. In addition, the overall platform is large in size and cannot be used conveniently.
