Abstract

The present invention discloses a testing machine for an impact test, comprising a testing bench, and a testing frame arranged on the testing bench. The testing machine is characterized in that: the testing frame comprises a screw, two guide posts, a sliding table, and a motor for driving the screw to rotate, wherein both the screw and the guide posts are vertically arranged on the testing bench, the screw is rotatable, and the guide posts are immovable; the tops of the two guide posts are provided with a cross beam used for fixing the motor, the upper end of the screw is connected with a main shaft of the motor; the sliding table cooperates with the screw through a screw pair, and cooperates with the guide posts through a moving pair; the sliding table is provided with a horizontal support, the support is provided with a magnetic base and a laser range finder which face the lower side; the bottom end face of the magnetic base and an emitting end of the laser range finder are located at the same height. The testing machine has the beneficial effects that: traditional manual positioning is replaced by a screw and motor mechanism, thus accuracy and testing speed can be greatly improved; positioning blocks not only can limit a tested object to move in the horizontal direction, but also can limit the tested object to move in the vertical direction, so that firmer fixing is achieved, and the test is facilitated.

Description

A kind of impact test test machine
Technical field
The invention belongs to checkout equipment technical field, be specifically related to a kind of impact test test machine.
Background technology
Have the electronic equipment of screen, the machines such as such as notebook computer, panel computer, mobile communication terminal, LCD screen, the finished product to be detected made or combined, needs the anti-impact force testing its body.
In the market test machine steel ball magnet base and fix its height lifting guide pillar between relative height be adjustable, the location of magnet base height relies on the scale that lifting guide pillar is carved to determine height, there is following shortcoming in this mode: after the steel ball of different-diameter is held by the magnet base above it, because diameter is different, what scale magnet base needs to adjust on, all need to do a little additive operation, operator uses will be more inconvenient.Mostly the height of magnet base is that by regulating manually, speed is slow, precision is low, often causes test result inaccurate.
Summary of the invention
The present invention proposes a kind of impact test test machine, can be quick and high-precisionly complete test.
Technical solution of the present invention: a kind of impact test test machine, comprises test board, is arranged on the testing jig on test board; Testing jig comprises and is vertically arranged on rotating leading screw on test board and Immobile two guide pillars, slide unit, and the motor driving leading screw to rotate; The top of two guide pillars is provided with the crossbeam for fixed electrical machinery, and the upper end of leading screw is connected with the main shaft of motor; Slide unit is coordinated with leading screw by screw pair, is also coordinated with guide pillar by moving sets; Slide unit is provided with the support of level, support is installed magnet base down and laser range finder; The bottom face of magnet base and the transmitting terminal of laser range finder are positioned at sustained height.
In the present invention, test board is provided with four slidably locating pieces, wherein two locating pieces can transverse movement on test board, and two other locating piece can lengthwise movement on test board.
In the present invention, the truncated rectangular pyramids of locating piece to be xsect be right-angled trapezium, and upper bottom surface is greater than bottom surface, locating piece is a dip plane for spacing side, and the angle of this side and surface level is 45 ~ 80 °.
In the present invention, locating piece is both medial surface aforementioned for spacing side to the horizontal part that locating piece comprises vertical portion and is connected with vertical upper end.
In the present invention, locating piece arranges sheet rubber on spacing side.
In the present invention, locating piece is provided with fastening bolt.
The beneficial effect that the present invention reaches:
1. utilize spindle motor mechanism to replace Traditional Man manual positioning, substantially increase precision and test speed.
2. the motion in the horizontal direction of locating piece technical ability constraint measured object, also can retrain measured object and move at vertical direction, makes fixing more firm, is convenient to test.

1 test board; 2 guide pillars; 3 leading screws; 4 slide units; 5 crossbeams; 6 magnet bases; 7 locating pieces; 8 measured objects; 9 motors; 10 supports; 11 laser range finders.
Embodiment
Below in conjunction with embodiment and accompanying drawing, technical solution of the present invention is described in further detail, but protection scope of the present invention is not limited to described embodiment.
Embodiment one
As shown in Figures 1 to 4, a kind of impact test test machine, comprises test board 1, is arranged on the testing jig on test board 1.Testing jig comprises leading screw 3, two guide pillars 2, slide unit 4, crossbeam 5, and motor 9.Screw mandrel and guide pillar 2 are all vertically arranged on test board 1, and leading screw 3 is positioned at the central authorities of two guide pillars 2, and leading screw 3 can rotate, and guide pillar 2 is for maintaining static.The top of two guide pillars 2 is provided with the crossbeam 5 for fixed electrical machinery 9, and the upper end of leading screw 3 is connected with the main shaft of motor 9.Slide unit 4 is coordinated with leading screw 3 by screw pair, is also coordinated with guide pillar 2 by moving sets.Slide unit 4 is provided with the support 10 of level, support 10 is installed magnet base 6 down and laser range finder 11; The bottom face of magnet base 6 and the transmitting terminal of laser range finder are positioned at sustained height.
On test board 1, slidable fit has four locating pieces 7, and wherein two locating pieces 7 can transverse movement on test board 1, and two other locating piece 7 can lengthwise movement on test board 1.Locating piece 7 for xsect be the truncated rectangular pyramids of right-angled trapezium, and upper bottom surface is greater than bottom surface, and locating piece 7 is a dip plane for spacing side, and the angle of this side and surface level is 45 ~ 80 °.This structure can be completely fixed measured object 8, thus prevents from being subjected to displacement in test process affecting test result.Locating piece 7 arranges sheet rubber on spacing side, thus the edge of protection measured object 8 is not knocked bad.Locating piece 7 is fixed on test board 1 by fastening bolt.
Embodiment two
In the present invention, locating piece 7 is both medial surface aforementioned for spacing side to the horizontal part that locating piece 7 comprises vertical portion and is connected with vertical upper end.
The course of work of the present invention and principle
Choose steel ball according to test request determination test height H, then starter motor 9 controls slide unit 4 and declines until suspend when the bottom face of magnet base 6 contacts with steel ball, and now laser range finder 11 is measured to test board 1 Emission Lasers is highly now H 1(i.e. steel ball size D).Then starter motor 9 controls slide unit 4 and rises to height H 2make H 2=H+H 1in time, is suspended, and magnet base 6 demagnetization makes steel ball free fall to the surface of measured object 8.Finally slide unit 4 is declined again and draws steel ball to continue test at starter motor 9.Often change the steel ball of a different-diameter, a height H must be completed while absorption steel ball 1test, just can automatically control to obtain test height H thus.
