Automatic feeding device of drop-hammer type impact testing machine

Abstract

The invention relates to an automatic feeding device of a drop-hammer type impact testing machine, comprising a transmission mechanism and a test sample gripper, wherein a lifting guide rail pair of the transmission mechanism is fixed on a testing machine vertical column by a connection base, the lifting guide rail pair is slidably connected with a lifting connection bracket, and the lifting connection bracket is sleeved on a lifting ball screw pair; a horizontal connection fixed plate is connected with the lifting connection bracket, a horizontal moving guide rail pair is arranged on the horizontal connection fixed plate, the horizontal moving guide rail pair is slidably connected with a horizontal bracket, and the horizontal bracket is sleeved on a horizontal moving ball screw pair; and a transition bracket is connected to the horizontal bracket, and the test sample gripper is installed on the transition bracket. The automatic feeding device disclosed by the invention is reasonable in structure, convenient to operate and use, high in feeding speed, accurate in location, high in working efficiency, safe and reliable. The automatic feeding device is applicable to automatic feeding of a drop-hammer type impact testing machine, a metal universal testing machine, etc.

Description

technical field [0001] The invention relates to a testing device for the impact resistance mechanical properties of metal materials, in particular to an automatic feeding device for a drop hammer impact testing machine. Background technique [0002] We know that in order to test the relevant mechanical properties of materials, people have designed various testing machines for testing the mechanical properties of materials. Drop hammer impact testing machine or pendulum impact testing machine is an essential and important equipment for testing the mechanical properties of metal materials against impact. At present, whether it is a domestic drop-weight impact testing machine or an imported drop-weight impact testing machine, the feeding and returning processes of the samples are mostly grasped by hand, or a simple manual tool is used to clamp the test. Sample. Its main disadvantages are: the labor intensity of manual operation is high, the work efficiency is low, and the fee...

AI Technical Summary

Problems solved by technology

Its main disadvantages are: the labor intensity of manual operation is high, the work efficiency is low, and the feeding speed cannot meet the requirements of the relevant national standards; the positioning of the sample is not accurate, which affects the accuracy of the test measurement; the drop hammer impact testing machine has a large impact energy , the sample is moved by the impact, the personal safety of the operator cannot be reliably guaranteed, and the risk is high

At present, the automatic feeding system of the testing machine seen in the market is mainly a six-axis linkage robot; this kind of high-precision robot, on the one hand, the testing machine does not have high requirements for its accuracy, and only requires the accuracy of the end position, not the accuracy of the motion process. , easy to cause waste of resources; on the other hand, due to its complex structure, cumbersome control, inconvenient use, and expensive
