Abstract
The utility model provides an anti-fatigue testing device for a lock rod of a sealing lock. The anti-fatigue testing device comprises a pair of flat tongs for fixing the position of one end of the lock rod, and a driving device for periodically enabling the other end of the lock rod to do reciprocating motions, wherein the driving device comprises a reciprocating air cylinder and a driving shaft; a piston rod of the reciprocating air cylinder is fixedly connected with the first end of the driving shaft; the second end of the driving shaft is provided with a lock rod clamping device. In a testing process, one end of the lock rod is fixed by the flat tongs and the other end of the lock rod is clamped by the lock rod clamping device; the reciprocating air cylinder is started to drive the driving shaft to do the reciprocating motions until the lock rod is broken; reciprocating times are recorded so as to obtain an anti-fatigue index of the lock rod. The anti-fatigue testing device for the lock rod of the sealing lock is simple in structure, small in size, high in automation degree and convenient to operate.
Description
Technical field
The utility model relates to a kind of anti-fatigue test device, particularly a kind of sealing lock locking bar anti-fatigue test device.
Background technology
Sealing lock is class lockset commonly used, if but in using, the excessive or number of bends of locking bar amount of bow too much all can cause the fracture of sealing lock locking bar, and affect the quality of sealing lock, so need to be tested the antifatigue bending property of sealing lock locking bar.Though current anti-fatigue test device kind on the market is many, all not too be applicable to the sealing lock locking bar is done to the antifatigue test.And the general volume of anti-fatigue test device on the market is large, complex structure, troublesome poeration.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of simple in structure, sealing lock locking bar anti-fatigue test device that automaticity is high.
For solving the problems of the technologies described above, the utility model provides a kind of sealing lock locking bar anti-fatigue test device, comprise the drive unit that can make the fixing flat-nose pliers of locking bar one end position and can periodically make the locking bar other end move reciprocatingly, described drive unit comprises reciprocating air cylinder and driving shaft, the piston rod of reciprocating air cylinder is fixedly connected with the first end of driving shaft, and the second end of driving shaft has the locking bar clamp device.
During test, locking bar one end is fixed with flat-nose pliers, the other end clamps with the locking bar clamp device, start reciprocating air cylinder, cylinder drives driving shaft and moves reciprocatingly, make locking bar back and forth bending until locking bar fracture, record reciprocal time, i.e. the bending times of locking bar, thus draw the antifatigue index of locking bar.Sealing lock locking bar anti-fatigue test device of the present utility model is simple in structure, volume is little, convenient operation.
As improvement of the present utility model, the locking bar clamp device is two pinch wheels, on the circumference of pinch wheels, clamping slot is arranged, and pinch wheels is fixed on driving shaft the second end, the clamping slot of two pinch wheels clamping locking bar that can cooperatively interact.Locking bar is clamped with two clamping slots, and locking bar is that point contacts with the pinch wheels way of contact, contacts with face and compares, and can prevent from testing the bending of hour locking lever generation multistage, causes test data inaccurate.
As further improvement of the utility model, the reciprocating air cylinder middle part is connected with the counter of recording and analyses bar reciprocal time.Without artificial counting, improve automaticity, save manpower.
The accompanying drawing explanation
Fig. 1 is the structural representation of the utility model sealing lock locking bar anti-fatigue test device.
Fig. 2 is the schematic diagram of the clamp device in the utility model sealing lock locking bar anti-fatigue test device.
Embodiment
Further illustrate the utility model below in conjunction with accompanying drawing and by preferred forms:
Sealing lock locking bar anti-fatigue test device, as depicted in figs. 1 and 2, comprise the drive unit 2 that can make the fixing flat-nose pliers of locking bar one end position 1 and can periodically make the locking bar other end move reciprocatingly; Drive unit 2 comprises reciprocating air cylinder 21 and driving shaft 22, the piston rod 21a of reciprocating air cylinder 21 is fixedly connected with the first end of driving shaft 22, the second end of driving shaft 22 has groove 22a, be fixed with locking bar clamp device 23 in groove 22a, the middle part of driving shaft 22 has back-up block 24 to support, and driving shaft 22 can be in the interior to-and-fro movement of back-up block 24.
Described locking bar clamp device 23 is two pinch wheels 23a, a clamping slot 23b is respectively arranged on the circumference of two pinch wheels 23a, pinch wheels 23a is fixed in the groove 22a of driving shaft 22 by bolt 23c, and locks with nut 23d, the clamping slot 23b of two the pinch wheels 23a clamping locking bar that can cooperatively interact.
Respectively there is a limited block 25 at the cylinder body two ends of reciprocating air cylinder 21, for the scope of limited piston bar 21a motion; Reciprocating air cylinder 21 middle parts are connected with the counter 26 of recording and analyses bar 21a reciprocal time.
The above is only preferred forms of the present utility model.Should be understood that; for the person of ordinary skill of the art; under the prerequisite that does not break away from the utility model principle, can also carry out some distortion or be equal to replacement the technical solution of the utility model, these also should be considered as belonging to protection domain of the present utility model.
