Detailed description of the invention
As Figure 1-3, the pre-machine drawing of chain of the present utility model, it comprises table top 1, motor 2, decelerator 3, driven chain shaft, oil cylinder and tension tester, motor 2, decelerator 3 is fixedly installed on the lower left quarter of table top 1, driven chain shaft is at least three, driven chain shaft and decelerator are in transmission connection and driven chain shaft is arranged on the upper left quarter of table top 1, oil cylinder comprises the first oily 51 cylinders and the second oil cylinder 52, first oil cylinder 51 and the second oil cylinder 52 are arranged on the right side of driven chain shaft, also comprise the first prestretching guide runner device 61 and the second prestretching guide runner device 62, first prestretching guide runner device 61 and the second prestretching guide runner device 62 are separately positioned on the right side of the first oil cylinder 51 and the second oil cylinder 52, chain first prestretching guide runner device 61 on the first prestretching guide runner device 61 and under the effect of the first cylinder thrust 51 moves right, tension tester 9 is arranged between the second oil cylinder 52 and the second prestretching guide runner device 62, driven chain shaft is connected with decelerator 3 gear drive, driven chain shaft specifically comprises the first driven chain shaft 41, second driven chain shaft 42 and the 3rd driven chain shaft 43, first oil cylinder 51 passes through power transmission rod 8 by power transmission on the first prestretching guide runner device 61, power transmission rod 8 is specially cylindrical, be threaded with the first oil cylinder 51, first, a guide revolving disk is provided with in the middle of second prestretching guide runner device, described guide revolving disk is specially patty and it rotates and leads to chain on described prestretching guide runner device.
During use, as shown in Figure 4, by chain successively around the first driven chain shaft, first prestretching guide runner device, second driven chain shaft, second prestretching guide runner device, on 3rd driven chain shaft, starter motor and oil cylinder, the rotation of motor drives the driving shaft on decelerator to rotate, the gear that rotates through of driving shaft connects and then drives the first driven chain shaft, second driven chain shaft and the 3rd driven chain shaft rotate respectively, to ensure the input and output that chain continues, in the process that chain constantly inputs, pretension on tension tester is what set in advance, namely the length that the first oil cylinder and the second oil cylinder stretch out is directly proportional to the size of pretension, along with first, carry out extend action to the right after second oil cylinder starts simultaneously, first oil cylinder passes through power transmission rod by the power transmission of the first oil cylinder on the guide revolving disk on the first prestretching guide runner device, so certain prestretching effect is carried out to the chain on guide revolving disk, the size of pretension is then directly reacted on the tension tester between the second oil cylinder and the second prestretching guide runner device, the prestretching principle of pre-machine drawing and prior art there is no too large difference.
Consider actual application, the number of driven chain shaft of the present utility model and oil cylinder can take the circumstances into consideration to increase according to practical condition again, be 6 or 9 etc., this will carry out matched design according to the size of the pretension of actual production actual needs, driven chain shaft of the present utility model is three, be not to restriction of the present utility model, but be described as example.
Consider actual application, motor of the present utility model, oil cylinder size will be mated with the size of tension tester, the operating condition making complete machine keep best, avoid occurring because oil cylinder is excessive, and the problem that motor cannot drive.
The pre-machine drawing of the chain that the utility model provides, can make pretension bring up to 20-25 thousand Ns by 10-13 thousand Ns by oil cylinder with coordinating of driven chain shaft, enhance the fatigue strength of chain, makes chain elongation in earlier stage drop to minimum.
Protection domain of the present utility model is not limited thereto, and is anyly familiar with those skilled in the art in the technical scope that the utility model discloses, the change that can expect easily or replacement, all should be encompassed within protection domain of the present utility model.Therefore, the protection domain that protection domain of the present utility model should define with claim is as the criterion.
