Torque force testing device for large-sized bolt

Abstract

The invention belongs to experimental and testing devices for mechanical parts, and specifically relates to a torque force testing device for a large-sized bolt. The device comprises a clamping and fixing part and a twisting part; the clamping and fixing part is formed by the way that two guide rails (22) are arranged on a pedestal (17), left and right guide sleeves (21) are arranged on each guide rail (22), a sliding pull base (28) is formed on the four guide sleeves (21), a bolt pull sleeve (7) is placed in an opening cavity of the sliding pull base (28), and two sides of the bolt pull sleeve (7) are sleeved in sliding rails (8) at two sides of the opening cavity of the sliding pull base (28) via sliding sleeves (6); a front end of a tensioning screw (2) is connected with the bolt pull sleeve (7); a locking screw disc (3) is sleeved on the tensioning screw (2); a rack (25) is arranged on the pedestal (17); and a shaft (19) of a wheel gear (24) engaged with the rack penetrates into the sliding pull base (28). The twisting part is orderly composed of a nut sleeve head (10), a rotary special-shaped head (11), a universal coupling (12), a torque sensor (13), a coupling (14), a reducer (15) and a motor (16). The torque force testing device is steady, reliable, accurate, safe and convenient in the test procedure, and can implement automatic test and improve the speed, the efficiency and the accuracy of the test.

Description

technical field [0001] The invention relates to a testing device for mechanical parts, in particular to a testing device for torque testing of large-diameter bolts. Background technique [0002] With the rapid development of the economy, the demand for energy is also increasing. At the same time, in order to protect our living environment and limited energy resources, the development of new energy and renewable energy has become the development direction of energy production in countries all over the world. As an important energy producing and consuming country in the world, China has attached great importance to the development of new energy and renewable energy in recent years. As a clean and renewable energy, wind energy has been paid more and more attention by countries all over the world. China's wind energy reserves are large and widely distributed. The wind power industry has developed rapidly and has become one of the major global wind power markets after Europe, th...

Problems solved by technology

Nowadays, in the case of large-diameter bolts, there is no suitable test device of this kind, and the small energy level and low torque cannot be tested, and the test data is not accurate, which will cause hidden dangers to the engineering used.
