Embodiment Construction

[0029] The fastener axial force-torque combined testing machine of the present invention includes a host computer and a microcomputer measurement and control system.

[0030] refer to figure 2 , the host machine includes a cabinet 1, two sliding doors 2 are arranged on the front of the cabinet 1, and a working platform 3 is arranged above the cabinet 1. The working platform 3 is provided with a motor reducer section A, a torque sensor section B and a reaction frame section C in sequence from right to left.

[0031] refer to image 3 , the motor reducer section A includes a motor (4) and a reducer (5), and the left shaft extension end 24 of the motor (4) is connected to the torque sensor 8 through the first shaft coupling 6 . The motor (4) is a servo motor, which has the characteristics of intelligent automatic gain adjustment, high speed and high response, and ultra-low vibration. The reducer (5) selects a planetary gear reducer, which has the advantages of less wear, smal...

Abstract

The invention discloses a shaft force and torque combined testing machine for a fastening piece. The shaft force and torque combined testing machine for the fastening piece comprises a host machine and a micro computer measurement and control system and is characterized in that the host machine comprises a machine cabinet which is sequentially provided with a motor, a reduction box, a torque sensor, a bearing pedestal, a counter force frame and a load senor from right to left. The load sensor is connected through the counter force frame and is arranged at one end of equipment, and the machine has an external load sensor structure, and effectively protects the sensor from being compacted by the fastening piece or a clamp, so that the acquired data is more stable and reliable. As the counter force frame is adopted, the length of a bolt extending out of a nut end is not needed to be adjusted by increasing or reducing washers so as to fulfill the aims of saving time, labor and trouble.

Description

technical field [0001] The invention relates to an effective torque test device, in particular to an effective torque test device for bolts, in particular to a combined axial force-torque test machine for fasteners. Background technique [0002] Fasteners are small, but they play a very important role in the power grid, ranging from small power fittings to large transmission and distribution line towers, substation frames, etc. Fasteners are important basic parts, their own quality or installation The quality will directly affect the quality and operation safety of power grid engineering. Due to the all-weather characteristics of the power grid, compared with the fasteners used in other fields, in addition to the general technical performance requirements, the anti-corrosion ability of the fasteners used in the power grid is also an important aspect. [0003] Among various coating methods for protecting steel substrates, hot-dip galvanizing is a very good one. It is in the...
