Abstract

The invention discloses a strength detection device for high-strength bolts, which belongs to the field of bolt detection. A strength detection device for high-strength bolts, comprising: a bracket, a base plate, an impact mechanism and a pressing mechanism, the bracket is arranged below the base plate to support the base plate, the base plate has a horizontal upper end surface, and the base plate A workbench is fixedly installed on the upper end surface, and several movable plates are arranged above the workbench, and the movable plates are arranged horizontally, and a first spring is arranged between the upper end surface of the workbench, and the There are vertically arranged slide rails on both sides, and the slide rails are fixedly connected to the base plate. A horizontally arranged pressing plate is arranged between the two slide rails. Rail sliding connection, the pressing mechanism is arranged directly above the pressure plate, and is used to press down the pressure plate; the upper end surface of the workbench is circular, and a number of mounting plate.

Description

technical field [0001] The invention relates to the field of bolt detection, in particular to a strength detection device for high-strength bolts. Background technique [0002] Bolt: A mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw (a cylinder with external threads), which needs to be matched with a nut to fasten two parts with through holes. This connection form is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. [0003] When evaluating product quality, it is necessary to test the strength of bolts. There are already many bolt strength testing devices on the market, but most of the existing testing devices have low efficiency and are not suitable for mass testing. Contents of the invention [0004] Aiming at the deficiencies of the prior art, the present invention proposes a strength detection device for hig...
