Hub unit radial numerical control rotate riveting device

Abstract

The invention provides a radial numerical control riveting device used in a wheel hub unit. The device comprises a main body frame, a rivet head and an electric pushing cylinder. A bedplate is arranged on the main body frame, and the electric pushing cylinder is arranged under the bedplate; the upper end of a push rod of the electric pushing cylinder is connected with a movable plate, and a pressure sensor and a displacement sensor are arranged in the electric pushing cylinder; the movable plate is provided with a tooling position rectifying device and an automatic tooling identifying device; the rivet head is arranged above the bedplate, and a torque sensor is arranged at one side of the rivet head; the upper end of the torque sensor is connected with a servomotor, and the lower end thereof is connected with a connecting shaft; the connecting shaft is connected with a connecting disk at the lower end of the rivet head. By riveting from bottom to top, the rivet head is arranged above the tooling, and riveting pressure and displacement are generated below the tooling; the electric pushing cylinder is taken as the power source of the riveting pressure and the displacement, and the riveting device has simple structure; the riveting pressure and the displacement are controlled by the sensor, thus realizing accurate control of the riveting pressure and the displacement and assuring the riveting quality.

Description

AI Technical Summary

Problems solved by technology

[0005] The above-mentioned patents still use a hydraulic system as power. In addition to problems such as complex structure and inconvenient maintenance, parameters such as downward rivet pressure, rivet depth, and rotational torque cannot be accurately controlled, and there are no safety protection facilities.

Existing rotary riveting equipment is difficult to guarantee the riveting quality of the flange radial assembly curling process after the hub unit is fitted
