The invention adopts a turnover hopper, which can automatically feed samples into the working positions in the tester and can automatically return the tested samples, to realize a complete mechanical motion of material feed, automatic positioning, prevented inclination of samples and material return. The drop hammer type tester turnover feed mechanism can confirm user's safety, improve the positioning precision of samples and improve working efficiency.
Description
Technical field
The present invention relates to a kind of metal material shock resistance mechanics performance test apparatus, specifically a kind of overturn feed mechanism of drop hammer type impact tester.
Background technology
We know that for the relevant mechanical property of material is tested, people have designed the testing machine of various test material mechanical properties.Landing impact testing machine or Charpy impact machine tester are the requisite visual plants of metal material shock resistance mechanics performance test.At present, no matter be homemade landing impact testing machine or import landing impact testing machine, the feeding process of its sample and material returned process all are to be grasped by staff, perhaps use a kind of easy hand-operated tools to come the clamping sample.Its major defect is: manually-operated labour intensity is big, and inefficiency, feeding speed all do not reach the requirement of concerned countries standard; The location of sample is inaccurate, influences the experimental measurement precision; Landing impact testing machine drop impact energy is big, and sample is hit mobile, and operator's personal safety can not get reliable guarantee, and is dangerous high.
Summary of the invention
Technical matters to be solved by this invention is to overcome above-mentioned the deficiencies in the prior art, provides a kind of simple in structure, easy for operation, and feeding is quick, accurate positioning, high efficiency, the overturn feed mechanism of drop hammer type impact tester that security performance is good.
The technical scheme that the present invention solves the problems of the technologies described above employing 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 hopper of the present invention 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 hopper of the present invention 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 hopper of the present invention 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 present invention 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.

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 hopper 1 of the present invention 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 hopper 1 both sides sidewall of the present invention 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 hopper 1 of the present invention 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.
When the present invention worked, hopper 1 arrived vertical position under the drive of motor, and the operator puts into sample in the middle of the sample block, and found 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 off-test of the present invention, 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 present invention adopts convertible hopper, and 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.
