Problems solved by technology

This method needs to take real samples on site, and the measurement accuracy is poor, especially it is difficult to measure the direction of different axes, which may cause repeated reprocessing of the bushing
Secondly, if the bushing needs to be replaced, it needs to be re-marked and positioned, and it cannot be assembled successfully at one time, which greatly increases the time cost and difficulty of the replacement work

Embodiment Construction

[0018] The structural forms introduced in the patent of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0019] figure 2 The illustrated embodiment is a diagram of a bolt assembly for adjusting the coaxiality of single and double lug connections proposed by the present invention. There is a twin-screw eccentric pin 4, two gap adjustment washers 3, two eccentric bushings 2 and two nuts 1.

[0020] image 3 The illustrated embodiment is a part diagram of the twin-screw eccentric pin 4 proposed by the present invention. It is divided into five areas: single-ear connection section 41, threaded sections 42 and 43, and double-ear connection sections 44 and 45, wherein threaded sections 42 and 43 are coaxial with double-ear connection sections 44 and 45, and are coaxial with single-ear connection sections. The axis of 41 has certain eccentricity δ1. The outer diameter of the one-ear connection section 41 is larger than the ...

Abstract

The invention aims at providing a bolt assembly with adjustable single-and-double-ear connecting coaxiality. The bolt assembly is characterized by comprising a twin-screw eccentric pin, two clearanceadjusting gaskets, two eccentric linings and two nuts. The double-screw eccentric pin is composed of a single-ear polished rod connecting shaft in the middle and bolt rods at the two ends. By means ofthe bolt assembly, connection assembly can be conveniently and rapidly achieved through adjustment of the assembly when hole heart deviation is generated in the connection process of a single-ear connector and a double-ear connector.

Description

technical field [0001] The invention relates to a bolt assembly, in particular to a bolt assembly with adjustable single and double lug connection coaxiality, which belongs to the field of mechanical connection. Background technique [0002] In practical engineering applications, due to manufacturing errors or position changes after disassembly, there will be cases where the lug connection holes cannot be coaxial and the bolts cannot be assembled. Especially for some double-ear to single-ear shear joint connections, first of all, the hole shaft fits with high precision, the gap is small, and the overall connection thickness increases. Once the center of the connection hole is even slightly misaligned, it may cause installation failure. In the case of the bolt assembly, see the attached figure 1 shown. Traditionally there are two solutions: [0003] 1) Finishing table is used: that is, the initial hole is made for the double-ear joint and the single-ear joint in the part m...
