Abstract

The invention provides a flat bottom non-riveting plastic connection device of a tabletting double spin-lock type. The flat bottom non-riveting plastic connection device comprises a base, and the baseis arranged along a plane; a case is vertically arranged above the base through an upright column, and a front end channel is formed in the case; a main shaft transmission mechanism is arranged abovethe front end channel, and non-riveting connecting mechanisms are arranged at the lower part of the main shaft transmission mechanism; connecting rod stamping mechanisms are arranged on the both sides of the case, and used for driving the non-riveting connecting mechanisms to move vertically; and the main shaft transmission mechanism is used for driving the non-riveting connecting mechanisms to rotate circumferentially, and a controller is electrically connected with the main shaft transmission mechanism and the connecting rod stamping mechanisms. The invention further provides a flat bottomnon-riveting plastic connection method of the tabletting double spin-lock type. The plastic connection device is rational in structure, and safe and quick in connection mode; and a plate connecting structure with high mechanical property and anti-torque can be formed, and the surface of one side of a connection point of the plate connecting structure is flat.

Description

technical field [0001] The invention relates to the technical field of plate connection, in particular to a device and method for double-twist-lock flat-bottom rivetless plastic connection device and method. Background technique [0002] "High-performance precision forming manufacturing science" is an important direction for the development of mechanical engineering disciplines. Lightweight technology with the goal of energy saving and emission reduction is considered to be one of the key technologies for high-performance forming manufacturing. Replacing or partially replacing traditional steel materials with light alloy materials will become the specific implementation method of future lightweight technology in aerospace, automobile, aircraft and other transportation industries. Welding and riveting are the two main ways of joining lightweight alloy materials and are widely used in the transportation industry. [0003] However, traditional welding (such as MIG welding, TI...
