Verification instrument of torque multiplier

Abstract

The invention discloses a verification instrument of a torque multiplier. The verification instrument mainly comprises: a pedestal; a torque output sensor, which is installed on the pedestal; a guide pillar, which is fixed on the pedestal; an elevating mechanism, which is cooperatedly installed on the guide pillar; a torque input assembly, which is fixedly installed on the elevating mechanism through a horizontal support plate; and a numerically controlled digital display instrument, which is additionally arranged. The torque input assembly is composed of a stepping motor, a decelerator, a shaft coupling, a torque input sensor and an input terminal conversion adaptor, wherein the stepping motor, the decelerator, the shaft coupling, the torque input sensor and the input terminal conversion adaptor are successively in shaft connection from top to bottom. The two sensors are corresponded upwards and downwards and central axises of the two sensors are superposed; besides, the two sensors are respectively connected with the numerically controlled digital display instrument through leads. And a central position at an upper end surface of the torque input sensor is provided with a polygonal blind hole that is plugged with an output terminal conversion adaptor; and the stepping motor is controlled by the numerically controlled digital display instrument. According to the invention, the instrument can be used conveniently; detected torque multipliers with various specifications and types can be localized on the verification instrument through an output terminal conversion adaptor, so that detection can be carried out; moreover, the instrument has advantages of good versatility and accurate measuring data.

Description

technical field [0001] The invention belongs to a detection instrument, and relates to a torque calibrator, in particular to a torque multiplier calibrator. Background technique [0002] At present, torque multipliers have various types and specifications, but there is no instrument and equipment specially for the verification and calibration of torque multipliers. In reality, the detection of torque multipliers is generally carried out by using a hydraulic torque wrench calibrator, and then matching with a digital display torque wrench for detection. This method has the following disadvantages: 1. The operation is difficult, the influence of human factors is large, and the accuracy of the test results is low; The indications are not synchronized, resulting in inaccurate measurement indications; 3. The detection accuracy level is low. Contents of the invention [0003] The object of the present invention is to overcome the deficiencies in the prior art, and propose a spe...
