A rim and tread linkage measuring device

Abstract

The invention discloses a wheel rim and tread linkage measuring apparatus comprising a supporting framework and a measuring assembly. The supporting framework comprises a horizontal top arm and at least two vertical arms. A horizontal guiding element passes through the vertical arms. The measuring assembly comprises a wheel rim thickness main measuring plate and a wheel rim width measuring plate which are disposed on the guiding element and which are capable of moving horizontally along the guiding element, an inner positioning plate and a rolling circular positioning contact which are disposed on the free ends of the vertical arms; and a wheel height measuring head and wheel rim auxiliary measuring plate which are capable of moving up and down along the vertical arms. The wheel rim thickness main measuring plate is connected with a measurement transition plate. The wheel rim and tread linkage measuring apparatus may measure all parameters just by one action, achieves an effect of instant contact instant acquisition, greatly increasing measurement efficiency, and may simultaneously QR values if corresponding parts are replaced and added.

Description

technical field [0001] The invention relates to a rail transit vehicle wheel set maintenance measurement and detection device. More specifically, the invention relates to a wheel rim and tread linkage measuring device used for measuring the parameters and dimensions of the rim and tread of a train wheel set. Background technique [0002] At present, most of the automatic measuring devices are used in the maintenance and measurement of rail transit vehicle wheels, and in various automatic measuring equipment, for the measurement of the parameters of the rim and tread of the wheel, most of the contact measuring mechanisms are used for the measurement of each parameter. The measurements are all measured and driven separately, which results in the acquisition of these parameters often with large accumulated errors or approximations, and the mechanism is huge and complex to control and the failure rate is high; for those non-contact measurements, due to the need for data The acq...

Problems solved by technology

[0002] At present, most of the automatic measuring devices are used in the maintenance and measurement of rail transit vehicle wheels, and in various automatic measuring equipment, for the measurement of the parameters of the rim and tread of the wheel, most of the contact measuring mechanisms are used for the measurement of each parameter. The measurements are all measured and driven separately, which results in the acquisition of these parameters often with large accumulated errors or approximations, and the mechanism is huge and complex to control and the failure rate is high; for those non-contact measurements, due to the need for data The acquisition and system analysis takes a long time (generally greater than 10 minutes / beat), and the non-contact measurement is greatly affected by the surface state, which affects the measurement quality and operating cycle

At present, there is no rapid and accurate measuring device that can strictly follow the logical relationship of each parameter, has a linkage mechanism, and can complete all parameters at the rim and rim with one drive.
