Problems solved by technology

[0004] With the rapid reduction of the weight of the car engine, when the user is assembling the car engine, the traditional torque tester not only cannot check whether the bolts and nuts are fully tightened, but also its operation process is very complicated, making it difficult for beginners to operate
[0005] Also, if you drive without using the proper torque to tighten the bolts and nuts, it may cause a terrible accident due to the leakage of engine oil, and abnormal oil combustion will also reduce the combustion rate

Abstract

The invention relates to a torque tester, which can achieve accurate test results through simple operations. Since the torque tester according to the present invention includes a torque sensor for detecting applied torque; an adapter for adjusting the gain of the detection signal input by the torque sensor and outputting the gain-adjusted detection signal as a display signal; and A digital multimeter for displaying on a display panel a number corresponding to the value of this display signal from the adapter, so that the user can turn the bolt or nut through the display after connecting the torque sensor to the digital multimeter through the adapter. The number on the display panel is used to check whether it is fully tightened, so that the present invention has the convenience of use and the simplicity of operation.

Description

technical field [0001] The present invention relates to a torque tester, and more particularly, to a torque tester capable of ensuring that a user can check whether bolts and nuts are sufficiently tightened with his required torque when installing an automobile engine. Background technique [0002] Typically, magnetic torque meters used to measure rotational power can be classified into two types, absorbing and transmitting. Absorption types include a friction meter that absorbs the power generated by the motor through friction between solids, a hydraulic meter that absorbs the power generated by exciting water through a spinner, and an air meter that absorbs the power generated by placing it in the air The power produced by a rotating fan, and a power meter that measures the power produced by a generator or an electrical load that consumes that power. [0003] Transmitting torque meters include a torsional force tester that measures the torsional force of a shaft that tran...
