Embodiment
As shown in Figure 1, Figure 2, Figure 3 shows, a kind of hand fire extinguisher powder pressing testing machine, mainly comprises stand 6, rigidity test table 4, push rod 14, moves up and down plate 9, fixes supporting plate 20, cam 23, servomotor 7, programmable controller PLC and machine governor sum counter 24.
Stand 6 and hand fire extinguisher 17 are arranged one to one, for placing hand fire extinguisher 17 and moving up and down in stand 6 for hand fire extinguisher 17, are provided with the guiding hoop 15 coordinated with hand fire extinguisher 17 in described stand 16.In this embodiment, stand 6 is provided with 3.And this embodiment is also further that described stand 16 is set to cylindrical shape, and stand 16 and guiding hoop 15 coaxial cable, hand fire extinguisher 17 can be placed so easily and move up and down for hand fire extinguisher 17 reliably.
The table top 19 of rigidity test table 4 is connected with fixed head 10 by bolt 11, and this table top 19 is the end face of deck plate 26.Stand 16 to be placed on described table top 19 and to be clamped by described fixed head 10.The bottom of rigidity test table 4 is provided with the coupling part be fixedly connected with ground base 1.In this embodiment, the coupling part bottom described rigidity test table 4 is fixed in ground base by the first foot bolt 2, and this first foot bolt 2 is combined with nut 3.
Push rod 14 and hand fire extinguisher 17 are arranged one to one, and top is the working end of jack-up hand fire extinguisher 17.Hand fire extinguisher 17 is provided with flame snuffer bottom bulkhead 13, flame snuffer annular bottom portion 18. coordinates with push rod is exactly flame snuffer annular bottom portion 18.The bottom of each push rod 14 is fixed on same and moves up and down on plate 9.The deck plate 26 of rigidity test table is provided with the through hole 12 with push rod 14 clearance fit.The height that push rod 14 jack-up hand fire extinguisher 17 departs from described table top 19 is equal to or less than the stroke of push rod 14.
The bottom surface moving up and down plate 9 is connected with mobile guide post 22.
Fixing supporting plate 20 is fixedly connected with described rigidity test table 4, can be that to weld also can be adopt web member connection.In this embodiment, fixing supporting plate 20 is fixed on described rigidity test table by bolt 8, and be positioned at the below of deck plate 26.Fixing supporting plate 20 is provided with the mobile guide hole 21 coordinated with mobile guide post 22.
Cam 23 drives mobile guide post 22 moving up and down with a fixed frequency and a fixed journey system.The described fixed frequency of this testing machine setting is 1Hz, and its fixed journey system makes hand fire extinguisher be 15mm by the height of jack-up, meets testing requirements.
Further design this cam 23 in the present embodiment, the wheel rim curve of this cam 23 is that the distance continuous print increase gradually that the process middle distance a bit doing gyration around fixed installation axis of cam by certain fixedly mounts axis is formed; The starting point doing gyration is designated as paraxial point 231, and the terminal doing gyration is designated as axle far away point 232; The dentation that the wheel rim curve structure at the straight line line between axle point 232 far away and paraxial point 231 and axle far away point 232 place is in an acute angle.
The design of this cam wheel rim curve, especially axle point 232 place far away is the dentation of acute angle, make mobile guide post 22 can leave axle far away point 232 when supporting, unexpected moves down, form an impact, make the collision forming an impact between the table top 19 of hand fire extinguisher 17 and rigidity test table, be conducive to the compacting dynamics of the powder improved in flame snuffer 17, thus raise the efficiency.
Servomotor 7 drives described cam 23 to rotate.In this embodiment, servomotor 7 is fixed in ground base by the second foot bolt 5, is combined with adjusting nut 6 with the second foot bolt.
Programmable controller PLC and machine governor sum counter 24 carry out control linkage by control line 25 with servomotor 7.
During work, servomotor 7 driving cam 23 rotates, and cam 23 coordinates with mobile guide post 22, and mobile guide post 22 moves up and down along the mobile guide hole 21 on fixing supporting plate 20.Mobile guide post 22 drives to move up and down plate 9 and drive further and is arranged on the push rod 14 moved up and down on plate 9 and moves up and down along the through hole 12 on rigidity test table 4.
When mobile guide post 22 drives and push rod 14 moves, push rod 14 jack-up hand fire extinguisher 17 moves up in hoop 15.When push rod 14 by hand fire extinguisher 17 jack-up to peak time, as shown in Figure 4, namely when the axle point place far away of cam coordinates with mobile guide post, cam is rotated further, mobile guide post can move down rapidly, causes push rod 14 to lose suddenly support to hand fire extinguisher 17, as shown in Figure 5, push rod 14 drops to rapidly table top less than 19, makes flame snuffer 13 and table top 19 rigid contact.Cam 23 often turns around and realizes once falling of hand fire extinguisher 17.
When anxious drop height degree in cam 23 structure is greater than 15mm, adjusting nut 6 and bolt 8 change push rod 14 lifting altitude and stroke, meet 15mm to make hand fire extinguisher 13 falling height.
Rotating speed and the counting of servomotor 7 are controlled by programmable controller PLC and machine governor sum counter 24, thus fall the table top 19 of rigidity level with the frequency of 1Hz from 15mm eminence in vertical direction while of realizing 3 hand fire extinguishers, the requirement of continuous 500 times.
The present invention is not limited only to above-mentioned embodiment.
