Device for detecting length of belt of engine of motor vehicle

Abstract

The invention discloses a device for detecting the length of a belt of an engine of a motor vehicle. The device comprises a platform, wherein a spring scale, guide rails, belt pulleys, a sliding block and a threaded rod are arranged on the platform; the belt pulleys are connected with the guide rails through the sliding block; the sliding block between the guide rails slides along the rail; the guide rails comprise a first guide rail and a second guide rail; the first guide rail and the second guide rail are arranged in parallel; and measuring scale marked lines are formed on the first guide rail. One spring scale serves as the standard stress application mode, load can be adjusted as required, and a hand wheel is used for adjusting the distance and the tensile force between the belt pulleys, so the device is convenient to operate. The device is simple in structure, easy to operate and high in detection efficiency. The belt pretightening force is continuously variable within the measuring range as required.

Description

technical field [0001] The invention belongs to production aids in the production process of engine components, and in particular relates to a detection device for the length of a motor vehicle engine belt. Background technique [0002] At present, in the field of engine component manufacturing technology, the engine belt plays an extremely important role in the entire engine operation process. The role of the engine belt is to transmit power and drive the generator, water pump, compressor and other equipment. If the corresponding belt breaks, these equipment will not work, which will cause in turn: the generator does not generate power, resulting in battery power loss, and the car cannot be started; Engine high temperature; air conditioner failure and other faults. The belt visible from the outside of the engine. It mainly drives the water pump, cooling fan, air conditioning compressor, power steering pump, generator, etc. If these parts are broken, they will not work. B...

AI Technical Summary

Problems solved by technology

[0004] The technical problem to be solved by the present invention is that the measurement method adopted in the prior art is to suspend the belt, add a heavy object as a load to give the belt a pre-tightening force, then measure the distance between the two pulleys, and convert the length of the belt The belt length precision of this prior art measurement is relatively poor, is unfavorable for the normal operation of starting, and when serious, will make engine can't work normally; Time-consuming and laborious, complex structure, complex operation, low efficiency and other technical problems, and provide A device for detecting the length of a motor vehicle engine belt
