Automatic hub type identifying device

An automatic hub type identifying device, comprising a feed roller bed, an electronic belt scale, a transfer roller bed, an identification device, a discharge roller bed and a processor, wherein the feed roller bed is configured to convey a hub to the electronic belt scale;

• the electronic belt scale is in data connection with the processor, and is configured to weigh the hub conveyed by the feed roller bed and transmit the weighing result to the processor;
• the transfer roller bed is configured to transfer the hub from the electronic belt scale to the identification device;
• the identification device comprises servo drive devices and micro contact displacement detecting devices connected to the servo drive devices, and the micro contact displacement detecting devices are in data connection with the processor;
• the servo drive devices are configured to drive the micro contact displacement detecting devices to contact the inner and outer edges of the hub when the hub reaches the identification device;
• the micro contact displacement detecting devices transmit the measured position information to the processor after contacting the inner and outer edges of the hub;
• the discharge roller bed is configured to carry the hub away from the identification device;
• the processor is configured to compare the weighing result of the electronic belt scale with a preset hub type-weighing result to obtain a possible range of the hub type;
• and the processor is also configured to calculate the dimension of the hub based on the measured position information of the micro contact displacement detecting devices, and compare the dimension with the preset hub type—weighing result to obtain a possible range of the hub type.
