Brief description of the drawings
Fig. 1 is the structural representation of large spring labor experimental rig.
Embodiment
The utility model is furtherd elucidate with reference to specific accompanying drawing, present embodiment is with the utility model technology Implemented under premised on scheme, it should be understood that these modes are merely to illustrate the utility model rather than limitation the utility model Scope.
As shown in figure 1, the utility model embodiment discloses a kind of large spring labor experimental rig, it includes multiple supports Bar 1, multiple support bars 1 are vertically arranged, and multiple support bar upper/lower terminals are respectively fixed with top plate 2 and bottom plate 3, multiple support bars 1 In one be fixed with the first limit switch 4 and the second limit switch 5;Top plate 2 is fixedly arranged in the middle of motor cabinet 6, and motor 7 is pacified vertically On motor cabinet 6, the drive shaft 8 of motor 7 is down-set, and the 3rd gear 9 is fixed with drive shaft 8, and top plate 2 is provided with first Clutch shaft bearing 10 and second bearing 11, bottom are respectively equipped with bearing chamber and second bearing room, clutch shaft bearing room and second bearing room First support 12, second support 13 and base 14 are fixed with plate 3, the 3rd is respectively equipped with first support 12 and second support 13 3rd bearing 15 and fourth bearing 16 are respectively equipped with bearing chamber and fourth bearing room, 3rd bearing room and fourth bearing room.
As shown in figure 1, clutch shaft bearing 10 of the present utility model and the inner ring of 3rd bearing 15 are separately fixed at the first screw rod On 17, the inner ring of second bearing 11 and fourth bearing 16 is separately fixed on the second screw rod 18, the parameter of the first screw rod 17 and the The parameter of two screw rods 18 is identical, and the signified parameter of the utility model is identical to be referred to, the other specification such as length, diameter is consistent.The The upper end of one screw rod 17 and the second screw rod 18 is respectively fixed with and 9 ratcheting and parameters all teeth of identical first of the 3rd gear Wheel 19 and second gear 20, the outside of 17 and second screw rod of the first screw rod 18 are respectively equipped with the first drive block 21 and the second driving The screw thread coordinated with the first screw rod 17 and the second screw rod 18 is provided with block 22, the first drive block 21 and the second drive block 22 so that First drive block 21 and the second drive block 22 can rotate on the first screw rod 17 and the second screw rod 18 respectively, the first drive block 21 Setting is flushed with the second drive block 22, that is, is maintained at same level height, its downside is fixed with a backboard 23, and the sidepiece of backboard 23 is consolidated Surely there is the limited block 24 with first limit switch and the cooperation of the second limit switch, the downside of backboard 23 is fixed with top board 25, Backboard 23 opens up through hole with the middle part of top board 25, and guard pin 26 passes through through hole from the top down, and base 14 is provided with and guard pin 26 Coordinate cotter way 27.
As shown in figure 1, guard pin 26 includes the bar of pin 261 of protection downside and is fixed on the limiting section of the upper end of pin rod 261 262, pin rod 261 can prevent from ejecting during spring breakage, and limiting section 262 can be such that guard pin 26 is transported with backboard about 23 It is dynamic.Before spring is put into, guard pin 26 is picked up upwards, then spring is placed on base 14, put down guard pin, is being pressed Guard pin 26 moves up and down with backboard 23 during contracting spring, and pin rod 261 enters on base 14 in the cotter way 27 opened up, In compression process, such as there is spring breakage, spring also will not collapse, therefore can play a very good protection.Work as test It is complete need take out spring when, first guard pin 26 is picked up upwards, then taking-up spring.
First limit switch 4 and the second limit switch 5 are used for the rotating of controlled motor 7, press button and start to test, electricity Machine 7 is rotated forward, and the first drive block 21 and the second drive block 22 are run downwards, the compression spring of top board 25, is opened when arrival second is spacing After closing 5 position, motor 7 stops, and then starts antiport, and the first drive block 21 is run up with the second drive block 22, bullet Spring resets, and after the first 4 position of limit switch is reached, motor 7 stops, and then stops, and then rotates forward, so circulation.
As the presently preferred embodiments, the downside of backboard 23 is the arc shape of opening upwards.Arc shape design can allow it to hold It is indeformable by bigger pressure, and then make experiment of this experimental rig suitable for large spring.
As the presently preferred embodiments, motor 7 is connected with a frequency converter.Because the general frequency of the experiment of large spring is smaller, But the pressure that its experiment needs is larger, frequency converter can be such that motor 7 is exported with the high torsion of the slow-speed of revolution, further make this experimental rig Suitable for the experiment of large spring.
In summary, the utility model by a motor by the gears of identical parameters respectively with parameter identical first Screw rod and the connection of the second screw rod so that the first screw rod and the second screw rod have identical rotating speed, and then cause the first drive block with Second drive block synchronously moves up and down, and compared with single screw rod drives, twin-screw stability is stronger.The pressure applied to spring is more equal It is even;Position by adjusting limit switch can allow this experimental rig to be applied to the bullet that different sizes and different compression travels require Spring;By setting spacer pin, contingency caused by collapsing spring is effectively prevented, increases the backboard of frequency converter and arcuate structure, makes this The practical experiment with large spring of experimental rig.
Described above is only preferred embodiment of the present utility model, it is noted that for the common skill of the art For art personnel, on the premise of the utility model principle is not departed from, some improvements and modifications can also be made, these improve and Retouching also should be regarded as the scope of protection of the utility model.
