Flying wheel energy storage type rivetless connection device of servo motor and connection method of connection device

Abstract

The invention discloses a flying wheel energy storage type rivetless connection device of a servo motor and a connection method of the connection device. The connection device comprises a motor, wherein an output shaft of the motor is connected with a shaft; a flying wheel is fixed on the shaft; a clutch is connected together with the flying wheel; the clutch is fixed at an optical shaft end of a screw rod; a screw rod nut is fixed with a nut sleeve; the nut sleeve is fixed on a sliding block; the sliding block is configured on a guide rail; the guide rail is fixed on a rack; a punch head is connected with the nut sleeve; a plate material is placed on the rack below the punch head; the rack is provided with a die cavity; the motor drives the flying wheel, the clutch and the screw rod to do rotary movement; the flying wheel stores energy for increasing the rotary inertia, and the rotary movement of the flying wheel is converted into the linear movement by the screw rod nut; the flying wheel is separated from the clutch the moment the punch head is in contact with the plate material, and the screw rod transmits a torque for driving the punch head to do linear impact movement for punching the plate material; and when the deformation amount reaches the expected requirement, and the plate material is filled in the die cavity of the rack, and the connection is finished. According to the flying wheel energy storage type rivetless connection device, the connector bonding quality and the production efficiency are guaranteed, and the connection device has the advantages of time-saving, labor-saving and energy-saving.

Description

technical field [0001] The invention belongs to the technical field of aluminum plate connection for automobiles, and in particular relates to a servo motor flywheel energy storage type rivetless connection device and a connection method thereof. Background technique [0002] With the continuous development of the automobile industry, people have put forward new requirements for energy conservation and environmental protection. Automobile lightweight is an important direction for the development of modern automobiles. It is of great significance for energy saving and emission reduction; every 10% reduction in vehicle weight can reduce fuel consumption by 8~ 10%, while emissions also fell by 4%. [0003] Automobile lightweight is closely related to the application of lightweight materials. Automobile lightweight materials include high-strength steel, aluminum alloy, engineering plastics and magnesium alloy. These four types of materials are used in automobiles. Due to the pr...

AI Technical Summary

Problems solved by technology

[0005] At present, some foreign research institutions are working on the research of rivetless equipment. The rivetless equipment speeds up the pace of energy saving and weight reduction of automobiles. The energy required is higher than that of riveting equipment, and the welding process is often not successful at one time. , Excessive impact force affects the welding quality, which can neither save energy nor cause strong hardening of the sheet during the riveting process, affecting the quality of the joint
