Replaceable arc rubber track friction coefficient testing device

Abstract

The invention discloses a replaceable arc rubber track friction coefficient testing device. The device comprises parallel side plates and a track base arranged between the side plates, wherein arc-shaped track inclination scales are arranged on the outer sides of the side plates, first kidney-shaped holes with the radians equal to that of the track inclination scales are also formed in the side plates, an indicating scale is fixedly arranged on the side edge of the track base, the lower end of the track base is movably connected with the arc center of the track inclination scales on the side plates, and a test track inclines to the lower end of the track base is arranged on the surface of the track base. The device can be used for measuring friction coefficients of multiple parts on tray tracks with different surface treatment and different fillets conveniently and quickly; a rubber track platform is replaceable, so that the device has higher universality; the tray climb angle and the overall design of the system can be designed more precisely on the basis of the measured friction coefficients, thus, the feeding efficiency can be improved, and noise can be reduced.

Description

technical field [0001] The invention relates to a friction coefficient testing device, in particular to a friction coefficient testing device for a circular arc track. Background technique [0002] The vibrating disc feeder is a device that arranges and feeds parts in an orderly manner. It is commonly used in automated assembly systems. Its feeding efficiency depends on three main factors. The first is the vertical direction of the parts under the alternating electromagnetic force. The acceleration on the top, the second is the climbing angle of the tray, and the third is the friction coefficient between the part and the tray. The design of the climb angle depends on the coefficient of friction. In addition, the size of the friction coefficient has a direct impact on the overall design of the vibrating disc feeder, as well as its feeding efficiency and noise parameters.

AI Technical Summary

Problems solved by technology

[0003] Since the track of the tray is mainly arc-shaped, it is difficult to measure the friction coefficient between the parts and this type of rubber tray. At present, the design of vibrating tray feeders is mostly based on a certain range of friction coefficient, not based on specific parts. The design is based on the actual friction coefficient between the vibration plate and the material plate, which will inevitably lead to the inability to fully improve the nail feeding efficiency of the vibrating plate and reduce the noise level of the system, and generally fail to achieve the optimal design of its feeding design
