Embodiment Construction

[0013] The following description in conjunction with the accompanying drawings of the experimental apparatus described in further detail.

[0014] like figure 1 The one shown fastening bolt experimental apparatus to ensure concentricity. There are four holes in the jig main body 1, for the fixed plate or bench. Fastening the two sliders (2a and 2b) is placed over the jig main body 1 within the T-slot, the feed screw (3a and 3b) mounted on the jig main body 1 symmetrically arranged on both sides of the threaded hole, and allowed to through fastening two sliders (2a and 2b) of the blind hole. Adjusting the position of the initial feed screw (3a and 3b), and leave enough space for the installation of the pressure sensor 4 is annular. Custom clamping jaws clamp 5 is placed in a rectangular groove of the upper body, and then fastening the gasket 6 used in the experiment is placed in the upper portion of the clamping block 5 customized annular groove to ensure that the gasket 6, clampin...

Abstract

The invention discloses a bolt fastening experimental device for ensuring coaxiality, which mainly consists of a fixture main body, a fastening slide block, a feed screw rod, a custom clamping block, and an annular pressure sensor for measuring clamping force, a screw rod, and a nut and gaskets etc. Threaded holes are arranged symmetrically on both sides of the fixture body, and the two feed screw rods are adjusted to move the fastening slider so that it slides in the T-shaped slot inside the fixture body. The fastening slide block can also ensure the coaxiality of the screw rod and the pressure sensor while restricting the rotation of the head of the screw rod. The gasket is placed in the groove on the upper part of the clamping block, and the clamping block can be customized according to the bolt specification and the type of gasket. The device can realize the fixing of the screw rod during the fastening experiment process, and ensure the coaxiality requirements of the bolt connection structure, improve the efficiency of the bolt fastening experiment, and reduce the uncertain factors in the bolt fastening experiment process.

Description

Technical field [0001] The present invention relates to a test apparatus to ensure that the fastening bolt concentricity, belonging to the field of manufacture and assembly machinery. Background technique [0002] Bolted because of its simple structure, reliable connection, the advantages of easy handling, etc., it is widely used in various mechanical members. Referring to GB / T 16823.2-1997 General tightening threaded fasteners, using a variety of fastening methods clamping force will cause the dispersion to some extent. Dispersing the bolt clamping force caused by many factors, such as manufacturing errors of the connecting member, bolted assembly error, thread manufacturing and inconsistent. Engineering practice in order to improve the quality of the assembly, the bolt is often used with the batch experiments, a pressure sensor monitoring the clamping force of the bolt, the thread friction coefficient measured in advance and the pressure receiving surface friction coefficient...
