Motor rotation shaft assembly method and assembly machine implementing same

Abstract

The invention discloses a motor rotation shaft assembly method comprising the steps as follows: a rotary disc is arranged on a machine stand, and an axis rod fixed seat detection device, an axis rod transportation and installation device, an axis rod detection device, a lower pressing ring transportation and installation device, a lower pressing ring detection device, a first oil injection device,a gear transportation and installation device, a second oil injection device, an upper pressing ring transportation and installation device, an upper pressing ring detection device, a finished product moving device and a defective product recycling device are arranged around the rotary disc; a riveting device, a running-in device, a friction force detection device and a sorting device are installed on one side of the rotary disc; and a PLC control system for controlling the device is also installed on the machine stand. Five processes such as automatic assembling, riveting, detecting slippingfriction force and sorting are combined together. The invention also discloses equipment for implementing the method. According to the equipment and the method, the product friction force is controlled in a closed loop, the degree of automation is high, the production cycle of products is effectively shortened, the production cost is reduced; during a production process, detection can be performed according to user demands and product characteristics, the production status can be conveniently better analyzed, an alarm can be given for the abnormal condition during the production process; theproduction abnormity can be eliminated in time, and the product qualification ratio is ensured.

Description

technical field [0001] The invention relates to a machine and a method for assembling a motor shaft using the machine, in particular to an assembling method for a motor shaft and an assembly machine implementing the method. Background technique [0002] At present, DC motors are widely used in the world, and are used in many fields such as machinery, toys, and household appliances. There is an existing motor shaft such as figure 1 and figure 2 As shown, it consists of a shaft a, a lower pressure ring b, a gear c, and an upper pressure ring d that are sleeved on the upper end of the shaft a from top to bottom. The upper pressure ring mounting groove f of the pressure ring d, and the lower pressure ring installation groove g for accommodating the lower pressure ring b are provided on the reverse side of the gear c, and lubricating oil needs to be injected between each part, which is manually assembled by workers during assembly Complete, requires separate riveting equipment...

[0002] At present, DC motors are widely used in the world, and are used in many fields such as machinery, toys, and household appliances. There is an existing motor shaft such as figure 1 and figure 2 As shown, it consists of a shaft a, a lower pressure ring b, a gear c, and an upper pressure ring d that are sleeved on the upper end of the shaft a from top to bottom. The upper pressure ring mounting groove f of the pressure ring d, and the lower pressure ring installation groove g for accommodating the lower pressure ring b are provided on the reverse side of the gear c, and lubricating oil needs to be injected between each part, which is manually assembled by workers during assembly Complete, requires separate riveting equipment for riveting, also requires separate friction testing equipment for testing, the assembly speed is slow and the efficiency is low; in addition, due to the high labor cost in China at this stage, it is becoming more and more difficult for enterprises to recruit workers, so this kind of The cost of assembly and assembly is high and cannot cope with mass production
