The technical scheme in the invention for solving the above technical problem is: a kind of overturn feed mechanism of drop hammer type impact tester, it comprises bearing, be located at motor on this bearing and rotating shaft, connecting rod, hopper, it is characterized in that: motor links to each other with rotating shaft by spring coupling, rotating shaft is connected and fixed by connecting rod and hopper, hopper is done 90 degree upsets back and forth by connecting rod, rotating shaft under the drive of motor, be separately implemented at feeding and material returned action on horizontal direction and the vertical direction.
Sidewall and base plate around the utility model hopper comprises, the both sides sidewall is provided with U type groove breach, and is mounted with the sample support piece.
Be provided with groove in the middle of the sample support piece that the utility model hopper both sides sidewall is installed, the groove outside also is provided with block and pressing plate.Sample is placed in the groove, and in the process of feeding and impact specimen, sample neither can be toppled over also and can not splashed to the outside.
The front side wall center of the utility model hopper is by fixing a centering piece to medium-height trestle.So that the operator just can accurately locate sample when being put into sample on the hopper.
The utility model adopts convertible hopper, against existing technologies, it can send into sample the working position of testing machine device interior automatically, the sample after the off-test can also be sent automatically, has realized feeding, has located automatically, prevents that sample from toppling over, the complete mechanical action of the material returned one cover.Guarantee personal safety, also improved the bearing accuracy of sample greatly, improved work efficiency.

Fig. 3 is the structural representation of the utility model material returned state.
1. hoppers among the figure, 2. centering piece, 3. pair medium-height trestle, 4. pressing plate, 5. connecting rod, 6. spring coupling, 7. main coupling, 8. motor, 9. motor cabinet, 10. passive shaft coupling, 11. right supports, 12. left socles, 13. base plate, 14. rotating shafts, 15. samples, 16. blocks, 17. sample support pieces.
Embodiment
From Fig. 1, Fig. 2, Fig. 3 as can be seen, a kind of overturn feed mechanism of drop hammer type impact tester, it comprises bearing, be located at motor 8 on this bearing and rotating shaft 14, connecting rod 5, hopper 1.Bearing comprises base plate 13 and right support 11, left socle 12, and motor 8 is fixed on the base-plate 13 by motor cabinet 9.Rotating shaft 14 is installed in the middle of right support 11, the left socle 12.Motor 8 links to each other with rotating shaft 14 by spring coupling 6, and spring coupling 6 is made up of main coupling 7 that cooperatively interacts and passive shaft coupling 10.Rotating shaft 14 is connected and fixed by connecting rod 5 and hopper 1, and hopper 1 is done 90 degree upsets back and forth by connecting rod 5, rotating shaft 14 under the drive of motor 8, is separately implemented at the feeding action and the action of the material returned on the vertical direction of horizontal direction.
Sidewall and base plate around the utility model hopper 1 comprises, the both sides sidewall is provided with U type groove breach, and is mounted with sample support piece 17.Be weight reduction, be convenient to upset, can be provided with some emptying apertures on sidewall and the base plate.
Be provided with groove in the middle of the sample support piece 17 that the utility model hopper 1 both sides sidewall is installed, the groove outside also is provided with sample block 16 and pressing plate 4.Sample 15 is placed in the groove, and in the process of feeding and impact specimen, sample neither can be toppled over also and can not splashed to the outside.
The front side wall center of the utility model hopper 1 is by fixing a centering piece 2 to medium-height trestle 3.So that the operator just can accurately locate sample when being put into sample 15 on the hopper.According to the requirement of test method, the v v notch v of sample and the position deviation of tup striking point are no more than ± 2mm.Centering piece 2 is fixed on the hopper 1, can rotate with hopper, is positioned in the position in the middle of the main frame on the vertical line of tup striking point, and deviation is less than ± 0.5mm.V v notch v on the sample is aimed at the centering that sample can be realized in the tip of centering piece.The alignment deviation of sample 15 satisfies request of national standard less than ± 1mm.
During the utility model work, hopper 1 arrives vertical position under the drive of motor, and the operator puts into sample in the middle of the sample block, and finds the center by the centering piece.At this moment, press " feeding " button on the operator's console, hopper just can be with sample to arrive horizontal level, finishes the feeding process.By detecting the state of putting in place near switch, motor just stopped operating when hopper 1 was the level of state, and the feeding state finishes.As shown in Figure 2.
After the utility model off-test, the sample of fracture directly drops on the bottom of hopper, can flip out with hopper.By detecting the state of putting in place near switch, motor just stopped operating when hopper 1 was vertical state, and material returned state finishes.Can take out the sample that drops on after the off-test in the hopper this moment, can put next piece sample to be checked simultaneously.As shown in Figure 3.
The utility model adopts convertible hopper, it can send into sample the working position of testing machine device interior automatically, sample after the off-test can also be sent automatically, realized feeding, located automatically, prevent that sample from toppling over, the complete mechanical action of the material returned one cover.Guarantee personal safety, also improved the bearing accuracy of sample greatly, improved work efficiency.
