Installing plate is bent plate more than, is welded with therein two fixed heads on line, and the first fixed head in horizontal direction is for installing connecting rods, and in vertical direction, the second fixed head of short end inner side is for linking springs.
The first fixed head and connecting rod pin joint.
The middle and upper part pin joint of the other end of second connecting rod and connecting rod.
On the second fixed head and connecting rod, be equipped with the spring hanging hole of fixing spring.
Advantage and effect:
This drop hammer impact testing machine of the utility model drops hammer and catches mechanism, has the following advantages and beneficial effect:
The utility model is by being arranged on the infrared sensor in mechanism, can find in time the landing of dropping hammer, and can in time signal be spread out of, and that avoids failing to judge to dropping hammer may; By being arranged on the parts such as solenoid in mechanism and iron core and connecting rod, realize the Quick Catch dropping hammer simultaneously, prevented the secondary pulse dropping hammer.This seizure mechanism and common comparing, shortened reaction distance, thereby improved accuracy and the sensitivity of reaction.

Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further:
The utility model relates generally to a kind of drop hammer impact testing machine and drops hammer and catch mechanism, comprise and drop hammer 1, it is characterized in that: drop hammer 1 below be provided with fishplate bar guide way 11, clashing into test specimen 9 is clamped between fishplate bar guide way 11 and the v block 10 of its below, intermediate plate 14 is positioned at the top of fishplate bar guide way 11, and be welded and fixed with it, on intermediate plate 14, be fixed with installing plate 5, the long end inner side of installing plate 5 vertical direction is fixedly connected with one end of magnet frame 12, in the middle of magnet frame 12, be provided with coil 2, the other end of magnet frame 12 is provided with can be at the iron core 3 of coil 2 axle upward slidings, the other end of iron core 3 is fixed with second connecting rod 13, the other end of second connecting rod 13 and connecting rod 4 pin joints, on the rotating fixed head being fixed in installing plate 5 inner side horizontal directions in upper end of connecting rod 4, the fishplate bar 6 that the lower end of connecting rod 4 and along continuous straight runs insert in fishplate bar guide way 11 is pegged graft, between the short end inner side of installing plate 5 vertical direction and connecting rod 4, spring 7 is installed, infrared sensor 8 symmetries are arranged on the left and right sides of intermediate plate 14.
Installing plate 5 is bent plates more than, on line, be welded with therein two fixed heads, on the center line of horizontal direction, weld the first fixed head 15, in vertical direction, on the center line of shorter one end, weld the second fixed head 16, the first fixed head 15 in horizontal direction is for installing connecting rods 4, and in vertical direction, the second fixed head 16 of short end inner side is for linking springs 7.
The first fixed head 15 and connecting rod 4 pin joints.
The middle and upper part pin joint of the other end of second connecting rod 13 and connecting rod 4.
On the second fixed head 16 and connecting rod 4, be equipped with the spring hanging hole for fixing spring 7.
On fishplate bar 6, the position of corresponding 1 whereabouts of dropping hammer can also have groove, places rubber in groove, the impact of buttcover plate in the time of can playing like this buffer action and drop hammer to alleviate.
During the utility model work:
First installing plate 5 is fixed on to fishplate bar guide way 11 upper surface places, and coil 2, iron core 3, connecting rod 4 and spring 7 are installed by diagram, by v block 10 and fishplate bar guiding, test specimen 9 is clipped; When coil 2 no power, under the pulling force effect of spring 7, connecting rod 4 is swung to the right, thereby drive iron core 3 and fishplate bar 6 to move right, reserve 1 test space impacting with test specimen 9 that drops hammer; After on-test, will drop hammer 1 is placed on specified altitude, and then allowing drops hammer 1 does the movement of falling object, and when the infrared ray of the 1 blocking-up infrared ray sensor 8 that drops hammer, infrared sensor 8 has just obtained the signal of 1 landing of dropping hammer, and signal is outwards exported; Extraneous processor is received after the signal of infrared sensor 8, to coil 2 energisings, due to the effect of magnetic field force, by iron core 3 to lira, because magnetic field force is much larger than the pulling force of spring 7, thus connecting rod 4 swing left rapidly, thus drive fishplate bar 6 to be moved to the left rapidly along fishplate bar guide way 11; From infrared ray sensor 8, capture falling signal very short to this time of rebounding 1 impact of dropping hammer, so eliminated fishplate bar 6, hinder 1 possibility of impact test piece 9 for the first time of dropping hammer; Because position and test specimen 9 that fishplate bar 6 arranges are very approaching, so also got rid of owing to dropping hammer overweight or kicking the beam and enough height that cannot rebound, make fishplate bar 6 cannot capture the possibility of dropping hammer.
Conclusion: this mechanism has improved the Stability and veracity of drop-weight test greatly.。
