Detector for hydraulic torque wrench

Abstract

The invention discloses a detector for a hydraulic torque wrench, mainly comprising a torque sensor (3) and a thrust location mechanism fixed on a shell (2). The detector for the hydraulic torque wrench is characterized in that a signal output end of the torque sensor (3) is connected with a digital display (1) provided with an operation panel; a square hole (4) is arranged on the upper end surface of the torque sensor; a rotary connector (6) connected with the wrench head is plugged in the square hole (4); the thrust location mechanism is a counter-force arm stop block (7) the position of which can be adjusted. The invention has the advantages of simple structure, convenient and quick plug-in of the torque sensor and the rotary connector; the counter-force arm stop block has adjustable positions and is suitable for detecting the hydraulic torque wrenches with different models; the digital display can directly display the detected torque value, has the functions of automatic warning and self-detection and is safe and reliable to use.

Description

technical field [0001] The invention belongs to detection instruments, in particular to a hydraulic torque wrench calibrator. Background technique [0002] At present, there are various types of hydraulic torque wrenches with different specifications, but there are very few instruments for verification and calibration of hydraulic torque wrenches. The existing hydraulic torque wrench testers have the following disadvantages to varying degrees: 1. The structure is complex, difficult to manufacture, and easy to damage; 2. The versatility is poor, and it cannot meet the verification of different types of hydraulic torque wrenches at the same time; 3. The torque value is not directly However, it is necessary to convert according to the applied hydraulic value, which may easily cause inaccurate verification values, and it is difficult to be found when the force exceeds the verification value, which may easily cause damage to the hydraulic torque wrench.

The existing hydraulic torque wrench testers have the following disadvantages to varying degrees: 1. The structure is complex, difficult to manufacture, and easy to damage; 2. The versatility is poor, and it cannot meet the verification of different types of hydraulic torque wrenches at the same time; 3. The torque value is not directly Instead, it needs to be converted according to the applied hydraulic pressure value, which will easily cause inaccurate verification value, and it is difficult to be found when the applied force exceeds the verification value, and it is easy to cause damage to the hydraulic torque wrench
