End face run-out and bolt detection integrated machine for third generation hub unit

Abstract

The invention discloses an end face run-out and bolt detection integrated machine for a third generation hub unit. A measuring table on a workbench can position and support a bearing to be detected; a light source and an image acquisition device symmetrically distributed on two sides of the measuring table image the bearing; a bearing outer ring flange positioning device can fix and position a bearing outer ring flange; the lower end of a measuring panel capable of lifting and being rotationally positioned above the measuring table can just press against the upper end face of a bearing inner ring flange, and the measuring panel is also provided with a bolt hole for inserting an upper bolt of the bearing inner ring flange; a longitudinal driving device and a rotary driving device can separately drive the measuring panel to longitudinally lift and intermittently rotate to the set angle, and a contact at the upper end of a measuring pen can just press against the lower end surface of the measuring panel; and a controller controls the bearing outer ring flange positioning device, the longitudinal driving device and the rotary driving device to act, and controls a measuring result output device to output the detection result. The integrated machine can detect two indexes at one time, and is quick in detection and exact in detection value.

Description

technical field [0001] The invention relates to an automatic detection device, in particular to a third-generation hub unit end face runout and bolt detection integrated machine. Background technique [0002] The third-generation hub bearing unit simplifies the supporting structure of the automobile wheel, and integrates the steering knuckle flange and the outer ring, so that the supporting function of the bearing and the connection and transmission of the hub flange and bolts are highly integrated, further realizing multi-functional integration. , Unitization, small size and light weight, the high-performance non-detachable sealing structure is adopted to achieve the effect of permanent sealing. It is equipped with two flanges, one is used to install on the wheel and brake disc assembly, and the other is used to fix Suspension, the third-generation wheel hub bearing significantly simplifies the cornering design. However, when leaving the factory, it is necessary to detect b...

[0002] The third-generation hub bearing unit simplifies the supporting structure of the automobile wheel, and integrates the steering knuckle flange and the outer ring, so that the supporting function of the bearing and the connection and transmission of the hub flange and bolts are highly integrated, further realizing multi-functional integration. , Unitization, small size and light weight, the high-performance non-detachable sealing structure is adopted to achieve the effect of permanent sealing. It is equipped with two flanges, one is used to install on the wheel and brake disc assembly, and the other is used to fix Suspension, the third-generation wheel hub bearing significantly simplifies the cornering design. However, when leaving the factory, it is necessary to detect both the end face runout of the bearing flange and the bolts on the flange of the inner ring of the bearing. At present, it is manually step by step Detected, the detection speed is slow, the accuracy of the detection results is low, and the cost of manual detection is high
