Inner center wheel inner diameter measuring mechanism

Abstract

The invention discloses an inner center wheel inner diameter measuring mechanism which comprises a base, a movable plate, a fixed seat and an inverted T shaped block. A screw motor is fixedly mountedon a motor seat, a screw rod seat of a ball screw rod is fixedly connected to the movable plate, the fixed seat is fixedly mounted on a lower side of the movable plate, a first air cylinder and a high-precision contact type digital sensor are fixedly mounted on one side of the fixed seat, two sides of the inverted T shaped block are respectively fixedly connected a first elastic steel sheet and asecond elastic steel sheet, a telescopic end of the first air cylinder penetrates through a first through hole, and a probe of the high precision contact type digital sensor penetrates through a second through hole, and a contact head is fixedly connected to one side of each of a first strip-shaped plate and a second strip-shaped plate. Through design of the high-precision contact type digital sensor, an inner diameter of an inner center wheel can be quickly detected; the inner diameter of the inner center wheel is resisted via the contact head, influence exerted by the irregular structure ofthe inner center wheel is prevented, and accurate and convenient measurement can be realized.

Description

technical field [0001] The invention relates to the technical field of auto parts detection, in particular to an inner diameter measuring mechanism of an inner wheel. Background technique [0002] Auto parts are the various units that make up the whole car and a product that serves the car. The classification of auto parts includes: engine parts, turning parts, brake parts, steering parts, walking parts, electrical instrument parts, car lamps, car modification, security and anti-theft, car interior, car exterior, comprehensive parts , audio-visual appliances, chemical care, body and accessories, maintenance equipment, power tools, etc. [0003] Existing car inner wheels need to be inspected after production is completed, but the inner diameter of the inner wheel is irregular and cannot be detected by ordinary devices. Now most factories are manually inspected by inspectors sequentially. Manual inspection takes a long time and is inefficient. Low, the detection is prone to ...

[0003] Existing car inner wheels need to be inspected after production is completed, but the inner diameter of the inner wheel is irregular and cannot be detected by ordinary devices. Now most factories are manually inspected by inspectors sequentially. Manual inspection takes a long time and is inefficient. Low, the detection is prone to errors, and a single product needs to be measured multiple times to ensure the accuracy of the inspection
