Preloading bolt assembly equipment and method

Abstract

The invention discloses preloading bolt assembly equipment. The preloading bolt assembly equipment comprises a press machine, a mounting support, a mechanical arm and pressure bars. A piston rod of a pressure cylinder of the press machine drives a movable middle plate of the press machine to move. The mounting support is fixedly connected with the movable middle plate of the press machine. The mechanical arm and the pressure bars are fixedly mounted on the lower portion of the mounting support. A wrench is mounted at the tail end of the mechanical arm. The mechanical arm rotates to drive the wrench to rotate. Pressure of the operating compression amount of a compression spring of the mechanical arm forces the wrench to move to tighten a preloading bolt to be tightened. The preloading bolt assembly equipment discloses by the invention has the functions of high-pressure-intensity preloading and bolt tightening, is full-automatic, suitable for an automatic production line and wide in application range, and can be used preloading assembly of various kinds of assembling components. The invention further discloses a method for assembling bolts by using the preloading bolt assembly equipment.

Description

technical field [0001] The invention belongs to the technical field of bolt assembly equipment, and relates to a preloaded bolt assembly equipment, and also relates to an assembly method using the above-mentioned equipment. Background technique [0002] The contact pressure of the mechanical joint surface is described by the pressure p, and the unit of the pressure p can be Mpa (N / m 2 , ie N / mm 2 ) indicates that the general mechanical joint surface pressure p below 1Mpa is low pressure, 1~6Mpa is medium pressure, and above 6Mpa is high pressure. [0003] The assembly of two parts connected by multiple bolts, hereinafter referred to as assembly assembly, can be assembled manually or automatically by mechanization. For the automatic assembly of assembly components connected by multiple bolts, when the distribution distance between the bolts is large enough, a pressure mechanism can be used to compress the two parts, and a multi-bolt tightening mechanism is used to connect a...

AI Technical Summary

Problems solved by technology

For the automatic assembly of assembly components connected by multiple bolts, when the distance between the bolts is large enough, a pressure mechanism can be used to compress the two parts, and a multi-bolt tightening mechanism can be used to connect and assemble multiple bolts of the assembly assembly; However, for the case where the distribution distance between the bolts is small and the pressure on the joint surface is high pressure, the pressure mechanism of high pressure and multiple bolt tightening mechanisms cannot exist at the same time.
