Embodiment
Be described in detail below in conjunction with accompanying drawing the utility model.
See Fig. 1 to Fig. 5, a kind of impulse withstand test machine of knapsack, comprise base 11 and the bracing frame 12 being fixedly installed on base 11, described base 11 is provided with the model 13 for fixing knapsack, described base 11 is also provided with the elevating mechanism 2 for regulating the upper and lower displacement of described model 13, and support frame as described above 12 is provided with the percussion mechanism 3 for impacting knapsack; The principle of work of this impulse test is: first carry on the back on model 13 by the knapsack for carrying out testing, and then utilizes elevating mechanism 2 to regulate the height of model 13, and percussion mechanism 3 is impacted knapsack at certain height; This testing machine can carry out impulse withstand test to knapsack, then according to the result of test, production run is controlled accordingly, also may be used for the batch testing to finished product knapsack, its structure is simple, easy to use, and it utilizes displacement to respond to can obtain accurate test data.
In the technical program, the carrier 32 that described percussion mechanism 3 comprises slide 31 and is slidably connected with slide 31, the top of described slide 31 is provided with the electromagnet 33 can drawing carrier 32, the bottom of described carrier 32 is connected with extension bar 34, described extension bar 34 is connected with ram hammer 35, also comprises the driving mechanism 36 for driving described carrier 32 upward sliding.Before impulse test, described ram hammer 35 contacts with the bottom of knapsack, then, under the effect of driving mechanism 36, carrier 32 is promoted, make ram hammer 35 be promoted to certain test height thereupon, such as: first utilize elevating mechanism 2 to regulate model 13 height, ram hammer 35 is contacted with knapsack, this position is impact zero-bit, at this moment, driving mechanism 36 drives carrier 32 to promote ram hammer 35, when carrier 32 lifting puts in place, shock height as test is 25mm, namely hoisting depth is set to 25mm, then electromagnet 33 powers up, it is made to be adsorbed by carrier 32, cylinder resets, then electromagnet 33 disconnects power supply, carrier 32 is under the gravity of ram hammer 35, downwards knapsack is formed and impact, when reaching certain impact number of times or knapsack moves down certain numerical value, it can judge test result according to corresponding standard.
In the technical program, described carrier 32 comprises top board 321, base plate 322 and guide pillar 323, and described guide pillar 323 is arranged with spring 324, and described base plate 322 is connected with top board 321 by guide pillar 323, and described ram hammer 35 is connected with base plate 322.Because ram hammer 35 is when quick washing, larger impulsive force may be produced, and under the effect of spring 324, greatly can reduce the impact of impulsive force on slide 31.
Usually, after ram hammer 35 impacts one or many, knapsack always occurs to bottom offset, and in the technical program, described carrier 32 is provided with sensing chip 37, and described slide 31 is provided with the sense base 38 for sensing sensing chip 37.After ram hammer 35 impacts, described sense base 38 senses the current location of sensing chip 37, when knapsack occurs to bottom offset, its sensing chip 37 also can move down accordingly, its amount of moving down is recorded by sense base 38, then send data to elevating mechanism 2, allow elevating mechanism 2 driving model 13 move up and it is revised; Thus ensure that the height impacted each time is consistent, improve and impact accuracy.
In the technical program, described driving mechanism 36 is cylinder, and described cylinder is fixedly connected with bracing frame 12, and the piston rod of described pneumatic jack abuts with carrier 32.During work, the piston rod of cylinder withstands the top board 321 of carrier 32, carrier 32 is moved up until electromagnet 33 powers up and to adsorb carrier 32 afterwards.
In the technical program, described elevating mechanism 2 comprises elevating bracket 21, and described elevating bracket 21 is connected with screw rod 22, also comprises the motor 23 for driving described screw rod 22 to rotate.The principle of work of this elevating mechanism 2 is: motor 23 drives screw rod 22 to rotate, wherein, motor 23 is in transmission connection by gear and screw rod 22, screw rod 22 drives elevating bracket 21 upstream or downstream further, and then the model 13 being arranged at elevating bracket 21 is also elevated accordingly, thus conveniently the height of model 13 is regulated.
Above content is only preferred embodiment of the present utility model, for those of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, this description should not be construed as restriction of the present utility model.
