The invention relates to a three-spring elastic shaft automatic feeding screw tightening device. The three-spring elastic shaft automatic feeding screw tightening device is used for quickly and automatically replacing a battery pack of a new energy electric automobile and can also be used for automatically tightening screws of an automobile power assembly line. The three-spring elastic shaft automatic feeding screw tightening device is composed of an elastic tightening shaft, a shell body and a mounting base plate, wherein the elastic tightening shaft is located in the cylindrical shell body and is coaxial with the cylindrical shell body, a sliding bush is embedded in the lower portion of the shell body, and the bottom of the shell body is in threaded connection with the mounting base plate; the elastic tightening shaft is composed of a screw sleeve, an elastic shaft and a tightening connector, the tightening connector is of a stepped shaft structure, the upper section of the tightening connector is a guide surface and is in sliding fit with the sliding bush, the middle section and the lower section of the tightening connector penetrate out of a round hole of the mounting base plate, and the middle section of the tightening connector is sequentially provided with an upper sliding ring, a return spring, a lower sliding ring and a locking nut; a spline groove is formed inside the screw sleeve; and the elastic shaft is composed of three completely consistent spiral springs, and the three springs are coaxial. According to the three-spring elastic shaft automatic feeding screw tightening device, automatic feeding in the screw tightening process is achieved, the manufacturing cost is reduced, and meanwhile equipment light weight is achieved.
Description
technical field [0001] The invention relates to a three-spring elastic shaft automatic feed screw tightening device, which is used for fast and automatic replacement of battery packs of new energy electric vehicles, and can also be used for automatic tightening of screws in automobile powertrain assembly lines. It has a light and compact structure and low cost. specialty. Background technique [0002] With the gradual implementation of the new policy of our country's automobile industry, the proportion of electric vehicles in the production and sales of complete vehicles is getting higher and higher. The problem of long charging time for electric vehicles has always been the top priority in the development of new energy vehicles, and it is also one of the important factors restricting the use of electric vehicles. The rapid and automatic replacement of electric vehicle battery packs has also become a rapid battery replacement technology. By replacing the battery packs on el...
