Embodiment
Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Referring to figs. 1 through Fig. 4, the handling swinging mechanism of a kind of Charpy impact machine tester of the utility model one embodiment is proposed.This handling pendulum structure can comprise: drive unit 11, gearing 12, screw mandrel 13, feed screw nut 14, crossbeam slide block 15, connecting rod 17 and crank 16; Said crank 16 is provided with cylinder 161, hook 162 and ships and resell on another market 163; A hook end of 162 163 is connected with shipping and reselling on another market, and the other end is connected with cylinder 161, and 162 pin 163 rotations that rotate are linked up with in cylinder 161 drive of stretching;
When carrying pendulum, the cylinder rod of cylinder 161 stretches out and drives the hanging scroll that hook 162 hooks on the pendulum; Said drive unit 11 starts the back and rotates through gearing 12 drive screw mandrels 13; And drive to connect the feed screw nut 14 and crossbeam slide block 15 moving linearlies of one through rotatablely moving of said screw mandrel 13; Rotate by connecting rod 17 pulling cranks 16, pendulum is mentioned; When putting pendulum, the withdrawal of the cylinder rod of cylinder 161 drives the hanging scroll that hook 162 breaks away from the pendulum.This connecting rod 17 connects crossbeam slide block 15 and crank 16.Above-mentioned drive unit 11 can comprise motor and reductor.This gearing 12 can be belt driver.This drive unit 11, gearing 12, screw mandrel 13, feed screw nut 14 and crossbeam slide block 15 can be arranged on the frame.
In Charpy impact test, need rise to pendulum from initial natural putting position has big potential energy extreme higher position, releases energy, to accomplish impulse test again.
The O point is the rotation center of crank 16; Above-mentioned crossbeam slide block 15, connecting rod 17 and crank 16 are formed offset slider-crank mechanisms; With crossbeam slide block 15 is the driving link moving linearly; Driving crank 16 is to realize rotatablely moving in the center with the O point, proposes swing with completion and does, and realizes the pendulum process of putting forward of super large energy Charpy impact machine tester.
The power of motor and reductor passes to screw mandrel 13 through gearing 12, makes this screw mandrel 13 rotate, the feed screw nut 14 and crossbeam slide block 15 moving linearlies that then connect with screw mandrel 13.This O point is the rotation center of crank 16, also the rotation center of pendulum.Feed screw nut 14 and crossbeam slide block 15 link together through screw.Cylinder 161, hook 162, shipping and reselling on another market 163 is installed on the crank 16; And rotate with the rotation of crank 16; A hook end of 162 163 connects together with shipping and reselling on another market; The other end and cylinder 161 link together, and cylinder 161 is flexible can to make hook 162 pin 163 that rotates rotate, to realize the hook 162 and the action of breaking off relations.
Above-mentioned cylinder 161 can be provided with reversal valve, the control cylinder bar stretch out with the withdrawal.When carrying pendulum, the reversal valve switching-over is stretched out cylinder rod, and hook 162 has just hooked the hanging scroll on the pendulum; Starter motor and reductor make crossbeam slide block 15 begin to move upward from B; Crank 16 is done counterclockwise rotatablely moving, and drives pendulum around the rotation of O point, stop motion after crossbeam slide block 15 moves at B '; This moment, pendulum rotated to the extreme higher position that is provided with, had accomplished the process of carrying pendulum.After installing impact specimen, the reversal valve switching-over makes the cylinder rod withdrawal, and hook 162 and hanging scroll are thrown off, and hook 162 is in the unhook state, and pendulum is the O spot wobble in the effect lower edge of gravity, the beginning impulse test.
After test is accomplished, start and stop after drive motor moves downward crossbeam slide block 15 to turn back to the B point; Test once more like need, then can repeat said process again, realize putting forward again pendulum and the process of putting pendulum.
In another embodiment of the utility model, above-mentioned crossbeam slide block 15, connecting rod 17 and crank 16 can everybody be two or more, forms the two or multicrank slide block mechanism of biasing, to should screw mandrel 13 and feed screw nut 14 also can supportingly be provided with two or more.
The handling swinging mechanism of above-mentioned Charpy impact machine tester can be realized the handling of pendulum through slider-crank mechanism is set, and is simple in structure, has aesthetic property, security and practicality.
The above is merely the preferred embodiment of the utility model; Be not thus the restriction the utility model claim; Every equivalent structure or equivalent flow process conversion that utilizes the utility model instructions and accompanying drawing content to be done; Or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the utility model.
