Connecting piece trolley for automobile side wall conveying system

Abstract

The invention relates to the technical field of auxiliary equipment for automobile production, in particular to a connecting piece trolley for an automobile side wall conveying system. The connectingpiece trolley is provided with a walking base frame mounted on a conveying track, a power device for driving the connecting piece trolley to move along a connecting piece track is mounted on the walking base frame, a plurality of pairs of connecting piece devices are mounted on each of the two sides of the walking base frame in the direction of the connecting piece trolley, gas grabbing devices are also mounted at the bottom of the walking base frame, and positioning block devices matched with the gas grabbing devices are arranged on the connecting piece track at least at starting and ending points where the connecting piece trolley walks. The connecting piece trolley provided by the invention has the benefits that the starting point of displacement of the connecting piece trolley is accurately positioned by adopting pneumatic grabs and the positioning block devices, so that the accuracy of a joint between the connecting piece trolley and an upper piece trolley and the accuracy of a joint between the connecting piece trolley and a lower piece trolley are better met; and the degree of automation is high, no manual intervention is required for transportation of connecting pieces on the side walls, the performance is stable, and the labor cost is greatly reduced, and therefore, an application prospect is good.

Description

technical field [0001] The invention relates to the technical field of auxiliary equipment for automobile production, in particular to a piece connecting trolley used in an automobile side wall conveying system. Background technique [0002] In the automobile production workshop, it is necessary to transport the workpieces of the left and right sides of the car to the corresponding station of the main welding line of the welding workshop, so that the workers or robots on the main welding line can weld the left and right sides of the car. The traditional side transportation method The left and right side panels are usually transported independently by two trolleys, and the up and down transportation of the side panels by each trolley is realized by an electric hoist plus a scissor balance mechanism. In the actual production process, this traditional transportation method There are disadvantages such as slow side wall conveying speed, low production efficiency, high maintenanc...

[0002] In the automobile production workshop, it is necessary to transport the workpieces of the left and right sides of the car to the corresponding station of the main welding line of the welding workshop, so that the workers or robots on the main welding line can weld the left and right sides of the car. The traditional side transportation method The left and right side panels are usually transported independently by two trolleys, and the up and down transportation of the side panels by each trolley is realized by an electric hoist plus a scissor balance mechanism. In the actual production process, this traditional transportation method There are disadvantages such as slow side wall conveying speed, low production efficiency, high maintenance cost of conveying equipment, inaccurate pick-up and unable to meet the higher precision requirements of automated robot production, etc.
