Description
Technical field
The utility model belongs to experiment of machanics apparatus field, and in particular to a kind of self-adjusting three-point bending test device.
Background technique
Three-point bending test is the experiment for measuring a variety of materials bending strength, operating process are as follows: places sample
In on two supporting points spaced apart, apply load in two the intermediate of supporting point, it is ensured that between three supporting points
Two equal moments of flexure are formed, three-point bending occurs for sample under Moment.The type of three-point bending test device is numerous at present
It is more, but it is complicated for operation on guaranteeing both ends supporting point to the equidistant solution of intermediate supports point, and reliability is with making
It can be reduced with the growth of time, need to provide a kind of simple and reliable solution in order to solve this problem.
Summary of the invention
To solve the above problems, the utility model provides a kind of self-adjusting three-point bending test device.This reality
It is achieved through the following technical solutions with novel: a kind of self-adjusting three-point bending test device, comprising: support base, double helix spring
Thick stick, left end sliding shoe, left end pressure hammer, shield, vertical shift support, servo hydraulic cylinder, pedestal, intermediate pressure hammer, right end
Pressure hammer, right end sliding shoe.The servo hydraulic cylinder is bolted on the top of the pedestal, the vertical shift support
It is bolted with the end of the servo hydraulic cylinder, the bottom of the vertical shift support is welded with the intermediate pressure
Hammer, the shield are fixed by screws in the two sides of the vertical shift support.
As the scheme that advanced optimizes of utility model, the support base is dovetail groove guide rail, the right end sliding shoe and
The dovetail groove guide rail of support base described in drives edge of the left end sliding shoe by the double helix lead screw is mobile, and the right end is sliding
It is welded with the right end pressure hammer at the top of motion block, is welded with the left end pressure hammer at the top of the left end sliding shoe.
As the scheme that advanced optimizes of utility model, the left end of the double helix lead screw is into the double helix lead screw
It is left-handed for putting, and the right end of the double helix lead screw is dextrorotation to the midpoint of the double helix lead screw, drives the double helix lead screw
It is synchronous with the left end sliding shoe towards or away from movement that the right end sliding shoe may be implemented, ensure that from structural point described
Right end sliding shoe and the left end sliding shoe move synchronously, and meet right end sliding shoe described in any time and the left end is sliding
Motion block hammers equidistant requirement into shape to the intermediate pressure.
This self-adjusting three-point bending test device is compact compared to current three-point bending test apparatus structure and from structure
Angle improves the reliability of experiment, the stability of operation.
