Embodiment Construction

[0022] 1. System composition and function:

[0023] like figure 1 As shown, the present invention, except fuselage 14, fuel tank, electromechanical accessories etc., main components include: 1. power head A, 2. transmission system B, 3. tail chuck C, 4. control display system D.

[0024] 1) The power head A includes a motor 12, a hydraulic pump 13, and a hydraulic motor 1 in sequence. The hydraulic motor 1 is a stepping ultra-high pressure (including inner curve) motor, and the steering, torque and rotating speed are controlled by a PC.

[0025] 2) Transmission system B includes shaft coupling 2a, bearing and support 3a, shaft coupling 2b, torque sensor 4, shaft coupling 2c, bearing and support 3b, sleeve 5 and chuck 6 in sequence, and torque M1 transferred to the test piece. The left end of the sleeve 5 is placed in the shaft coupling 2c, which can be replaced at will and then locked. The right end is a hollow sleeve cavity, and a multi-angle (hexagonal, twelve-angled, tri...

Abstract

A torque and axial force joint test machine for wind power generation fasteners mainly comprises a (hydraulic) power head A, a (machinery) transmission system B, an adjustable tail chuck C and a control display system D. The maximum range is diameter (M72), over-length (4 m) torque (3000 Nm), axial force (3000 kN) and detection precision is 1.5 per thousand. An operation mode is controlled by a PC machine, which can automatically print relative diagrams and output data. The test machine has wide range, high accuracy, wide range of application, and low cost, and can be widely used for security test of the fasteners.

Description

Technical field: [0001] The invention relates to the detection of the safety performance of mechanical fasteners, in particular to a wind power generation fastener torque and axial force combined testing machine necessary for accurate testing of the torsional moment and axial tension of large-scale and high-strength fasteners. Background technique: [0002] High-strength fasteners are used for the detachable connection of various mechanical parts. They have become indispensable and important accessories in steel structures, wind power generation, vehicles, various machinery and national defense equipment. Astronomical numbers to count. [0003] In order to connect reliably and ensure safety, the bearing capacity and service life of high-strength fasteners for wind power generation (hereinafter referred to as "fasteners") must be fully guaranteed to be foolproof. Therefore, the torque and axial force detection of fasteners has become an indispensable safety guarantee. [00...
