Press-in riveting machine for automobile belt tensioner

Abstract

The invention relates to a special press-in riveting machine for an automobile belt tensioner, which is characterized in that a rotating seat is connected to a motor drive mechanism, and a workpiece positioning seat is coaxially arranged on the rotating seat; the workpiece positioning seat includes a seat cylinder and a positioning plate, two The compression cylinder is set in the seat tube, the first positioning pin and the second positioning pin are set on the positioning plate, the circular pressure plate and the V-shaped pressure plate are respectively connected to the piston rod of the compression cylinder; the upper part of the workpiece positioning seat is coaxially provided with a pressure riveting Mechanism, riveting mechanism includes electronic press, bottom plate, fixed plate, tendon plate, riveting head and pressure sleeve; one side of the unloading plate is equipped with a torque sensor and a stopper; one side of the workpiece positioning seat is movable 3D intelligent Measuring sensors. The invention has a simple and compact structure, can complete the pressing, riveting and measuring of the tensioning arm at one time, improves the automation level, reduces the labor cost, improves the production efficiency and the qualified rate of products, and reduces the production cost.

Description

technical field [0001] The invention relates to a special equipment, in particular to a special machine for pressing in and riveting an automobile belt tensioner. Background technique [0002] The assembly of automobile belt tensioners generally adopts assembly line assembly, with one operator for each station, many operators, various tooling, waste of labor, many errors caused by human factors, and low production efficiency. During assembly, such as Figure 5 As shown, tensioning arm 4', housing 3', positioning shaft, damping assembly, spring, pulley, etc. need to be pre-assembled into pulley tensioner pre-assembly 2' (hereinafter referred to as pre-assembly), and then the front wheel needs to be 1′ is press-fitted and riveted on the upper end of the positioning shaft of the pre-assembled part 2′. After the riveting, it is necessary to check whether the riveting is in place, the torque after pressing, and the size of the riveting mouth. The existing assembly line method req...

[0002] The assembly of automobile belt tensioners generally adopts assembly line assembly, with one operator for each station, many operators, various tooling, waste of labor, many errors caused by human factors, and low production efficiency

During assembly, such as Figure 5 As shown, tensioning arm 4', housing 3', positioning shaft, damping assembly, spring, pulley, etc. need to be pre-assembled into pulley tensioner pre-assembly 2' (hereinafter referred to as pre-assembly), and then the front wheel needs to be 1′ is press-fitted and riveted on the upper end of the positioning shaft of the pre-assembled part 2′. After the riveting, it is necessary to check whether the riveting is in place, the torque after pressing, and the size of the riveting mouth. The existing assembly line method requires Multiple stations, multiple operators, multiple sets of fixtures, detection devices and riveting tools, low production efficiency, high labor costs, manual pressing and riveting of the tensioning arm, due to the existence of human factors, it is easy to produce incorrect Qualified products, and the transfer and transportation between each process will increase the workload, affect the production efficiency and increase the production cost
