Fixing device for a spare tire of an automobile

Abstract

The invention discloses an automobile spare tire installing and fixing device. According to the automobile spare tire installing and fixing device, the structure is reasonable, a spare tire can be installed and positioned efficiently, and the station and process are stable and safe. The automobile spare tire installing and fixing device comprises a bearing base, a main lifting air cylinder and a pressing platform, the pressing platform is connected with a rotating body which is rotationally connected with a piston rod of the main lifting air cylinder, an angle motor is arranged above the main lifting air cylinder, an output shaft of the angle motor is connected with the rotating body, two ejection blocks backing onto each other are arranged below the pressing platform, transverse guide rods are arranged on the ejection blocks, the transverse guide rods are connected with the pressing platform in a sliding mode and slide in the horizontal direction, the ejection faces of the two ejection blocks face the outside of the pressing platform, and horizontal sliding power of the transverse guide rods is provided by a clamping air cylinder. The automobile spare tire installing and fixing device has the advantages that the spare tire can be grabbed effectively, and the labor intensity of workers is low; in the installing process, limiting and protecting are achieved, no interference will occur, various mechanisms achieve clear division of work and act smoothly and reasonably, and installing efficiency is high.

Description

technical field [0001] The invention belongs to the field of automobile production and assembly tooling, in particular to an automobile spare tire mounting and fixing device. Background technique [0002] During the production process of automobiles, it is necessary to install spare tires. At present, when vehicles are produced on the assembly line of automobile production OEMs, the installation of spare tires mainly depends on the operators to assemble the spare tire assembly from the previous tire assembly line. Take out the shelf, place the spare tire assembly in the corresponding installation position of the vehicle, then take the spare tire pressure plate, install it and fasten it. Since the weight of each spare tire assembly is about 18Kg, calculated according to the daily output of 240 units, the daily operator needs to hold the mobile spare tire assembly with a total mass of 4320Kg, and it takes about 25 seconds to assemble a spare tire pressure plate. The waist tim...

Problems solved by technology

Since the weight of each spare tire assembly is about 18Kg, calculated according to the daily output of 240 units, the daily operator needs to hold the mobile spare tire assembly with a total mass of 4320Kg, and it takes about 25 seconds to assemble a spare tire pressure plate. The waist time is as long as 100 minutes, the employees have a heavy workload, are prone to fatigue, and are prone to quality problems such as scratches on the interior panels of the rear wall, which increases the repair rate
