Part, accurate positioning and a kind of falling ball impact test machine for preventing steel ball shock cabinet.The utility model is by following technical side
Case is achieved:
A kind of falling ball impact test machine comprising upright frame, cabinet, test device and fixture, the cabinet include bottom
Plate and four sides coaming plate, rack are fixedly installed on chassis backplane, are set on the bottom plate of cabinet there are two mounting groove, on two mounting grooves
By bolt installation there are two the width limit plate moved along mounting groove, the middle part of width limit plate is equipped with width along extending direction
Limit plate through slot, two width limit plates insides, which are equipped with, to be bolted and can limit along the length that width limit plate through slot moves
Position plate, two length limit plates are equal L shape and are oppositely arranged that the test device includes the test of sliding being installed in rack
Frame, the measuring head for being fixedly installed in testing jig end, infrared ray position indicator and steel ball, the infrared ray position indicator are installed on test
The center of head is equipped with electromagnet on measuring head.
Further, elastic cushion is equipped on bottom plate.
Further, cabinet is equipped with machine box door.
Further, graduated scale is equipped with along extending direction in rack.
Further, the other end of testing jig is arranged on the rack and is fixed by hook knob.
The beneficial effects of the utility model
A kind of falling ball impact test machine, by measuring head center install infrared ray position indicator, downward projection illumination,
Width limit plate is set to move the adjusting that can realize clamp jaw width along bottom plate mounting groove, length limit plate is logical along width limit plate
Slot movement can realize the adjusting of fixture length, to be clamped to test specimen, make center and the infrared ray position indicator of test specimen
Projection be overlapped, the test specimen of Lai Shiying different shape and size needs, and adjusts very convenient and positions more accurate, has positioned
Cheng Hou, then the electromagnet on measuring head is powered, then steel ball is adsorbed on electromagnet, when falling sphere is tested, is pressed by control
Button powers off electromagnet, and measuring head is made to lose adsorption capacity to steel ball, and steel ball it is real will to complete falling sphere in free-falling to test specimen
It tests, it, will not due to the blocking of two length limit plates and two width limit plates after experiment is very convenient, and steel ball is fallen
Cabinet is hit in spring.
Detailed description of the invention
Fig. 1 is the utility model schematic view of the front view；
Fig. 2 is cabinet overlooking structure diagram；
1. machine box door in figure, 2. cabinets, 3. graduated scales, 4. racks, 5. hook knob, 6. testing jigs, the positioning of 7. infrared rays
Instrument, 8. measuring heads, 9. electromagnet, 10. steel balls, 11. mounting grooves, 12. width limit plates, 13. length limit plates, 14. width limit
Position plate through slot, 15. bottom plates, 16. coaming plates.
Specific embodiment
A kind of falling ball impact test machine comprising upright frame 4, cabinet 2, test device and fixture, the cabinet include
Bottom plate 15 and four sides coaming plate 16, rack is fixedly installed on chassis backplane, is set on the bottom plate of cabinet there are two mounting groove 11, two
By bolt installation, there are two the width limit plates 12 moved along mounting groove on mounting groove, and the middle part of width limit plate is along extension side
To width limit plate through slot 14 is equipped with, it is equipped with and is bolted and can be along width limit plate through slot on the inside of two width limit plates
Mobile length limit plate 13, two length limit plates are equal L shape and are oppositely arranged that the test device includes the installation of sliding
It is described red in the testing jig 6 in rack, the measuring head 8, infrared ray position indicator 7 and the steel ball 10 that are fixedly installed in testing jig end
Outside line position indicator is installed on the center of measuring head, and electromagnet 9 is equipped on measuring head.
Further, elastic cushion (not shown) is equipped on bottom plate.
Further, cabinet is equipped with machine box door 1.
Further, graduated scale 3 is equipped with along extending direction in rack.
Further, the other end of testing jig is arranged on the rack and fixed by hook knob 5.
The Infrared locator is existing commercial product.
Since a kind of falling ball impact test machine is projected downwards by installing infrared ray position indicator in measuring head center
