In addition to the tension test of the wire 4, the wire connection firmness test stand of the present embodiment may perform an experiment of performing a winding or swinging, or a rotation after fixing the connection end of the wire 4, that is, a so-called bending test, to test whether the connected wire 4 is separated from the connection terminal thereof when the wire is wound around a circumference to be bent. In specific practice, a plurality of threading holes 302 which are also arranged on the rotary table 3 can be arranged outside the mounting holes 301, one of the manufacturing modes of the threading holes 302 can be to arrange a rotatable shaft sleeve, the shaft hole of the shaft sleeve is used for the lead to pass through, and the shaft sleeve can be rotatably mounted on the rotary table 3 through a bearing. The rotating table 3 is characterized by further comprising a balancing weight, wherein the balancing weight is arranged below the threading hole 302 during operation, the balancing weight is fixed on the other end of the lead 4, namely, the bottom end of the lead 4 shown in fig. 1, so that the lead 4 is straightened, the lead 4 rotates along with the rotation of the rotating table 3, the connection reliability of the connecting terminals is tested, the rotating speed of the rotating table 3 can be detected in real time by arranging the rotating speed sensor 11 on one side of the inside of the table 1, such as infrared breakpoint triggering, counting of the rotating turns, accurate and adjustable rotating speed, and corresponding electric control elements are intensively arranged in the control box 13 on the upper part of one side of the table 1, the rotating speed is adjustable, the rotating turns and the rotating time are set, and full-automatic control of the whole equipment is realized.
As one of the specific implementation structures, as shown in fig. 1-3, the embodiment further includes a plurality of guide posts 9 vertically slidably mounted on the rack 1, the guide posts 9 are cylindrical rods, two ends of each guide post 9 are respectively and vertically fixed with a connecting plate, and the two connecting plates enable the guide posts 9 and the connecting plates to form an integral structure capable of moving up and down synchronously. More specifically, the pressing block 5 is horizontally and slidably mounted on the lower connecting plate 6, and an electrically driven screw rod 8 is mounted in threaded fit in the center of the lower connecting plate 6, and the screw rod 8 is used as a driving member for vertically moving in the integral structure, namely, the screw rod 8 is vertically mounted on the bench 1 in a self-rotating manner, so that the two connecting plates and the guide post 9 can move upwards or downwards together, and the operation is stable and the structure is reliable.
As shown in fig. 1-2, at the bottom of the lower connecting plate 6, a pair of baffle plates 14 arranged at intervals are specially fixed, the pair of baffle plates 14 can be arranged left and right, each baffle plate 14 is penetrated by a horizontally arranged fastening bolt 16 in a threaded fit manner, meanwhile, a bearing platform 15 is also fixed between the two baffle plates 14, the top end surface of the bearing platform 15 is fixed on the lower connecting plate 6 or directly fixed with the baffle plates 14 into a whole, and a pair of pressing blocks 5 mentioned above are horizontally and slidably installed at the bottom end surface of the bearing platform 15, and when in operation, the two fastening bolts 16 are closed, the corresponding pressing blocks 5 are pushed to be closed, so that the connecting end of the lead 4 is clamped, and the drawing and rotating experiment is carried out. For the manual initiative rotation lead screw 8 of being convenient for, like fig. 2, still be fixed with hand wheel 7 on lead screw 8 coaxially, this hand wheel 7 is used for holding when holding, can realize manual rotation lead screw 8, then make the binding post on connecting wire 4 top be pulled up, especially to tiny wire 4, it is comparatively practical, can rely on manpower visual perception strength, when lower connecting plate 6 rises to the settlement height, if wire 4 and its binding post have not come off yet, then indicate that the pulling test is qualified. During specific manufacturing, in order to enable the lower connecting plate 6 to stably move up or down, the guide post 9 and the screw rod 8 are installed at the axial sliding fit position of the rack 1 by adopting the shaft sleeve 10, the shaft sleeve 10 is subjected to quenching treatment, the hardness is higher, the shaft sleeve 10 is adopted to improve the accuracy of axial movement, and the replacement and the maintenance are convenient, so that the corresponding components do not need to be replaced integrally.
As another preferred embodiment of the terminal for clamping the lead wire 4, as shown in fig. 3, a worm wheel 17 may be coaxially fixed after the bottom end of the lead screw 8 passes through the lower connecting plate 6 in a threaded fit, the worm wheel 17 is engaged with a worm 18 rotatably mounted under the lower connecting plate 6, the lead screw 8 rotates, the worm wheel 17 rotates, and the worm 18 rotates with the rotation. At the same time, it is also necessary to have a drive stud 20 coaxially fixed to each of the two ends of the worm 18, which may be integrally formed. In addition, a sliding arm 19 is screwed on the drive stud 20, the sliding arm 19 may be in an L-shaped structure, one end of the sliding arm 19 is horizontally slidably mounted on the bottom surface of the lower connecting plate 6, if a T-shaped sliding block is adopted for sliding fit, the other end of the sliding arm is fixedly connected with a pressing block 5 to drive the pressing block 5 to horizontally move, in use, when the screw rod 8 rotates and the lower connecting plate 6 moves upwards, the two sliding arms 19 can be moved close to each other by synchronous rotation of the worm 18 and the drive stud 20 to perform a process of clamping the connecting terminal, when the screw rod 8 rotates to the lower connecting plate 6 to be located at a set height position, the two pressing blocks 5 just clamp the connecting terminal, then torque is continuously applied to the screw rod 8 at the limit height position, the lower connecting plate 6 continuously has an upward moving trend, and then a pulling force is generated on the connecting terminal clamped between the two pressing blocks 5, namely, a pulling force is generated on the wire 4, so as to observe whether the connecting terminal is separated from the wire 4 or not, or whether the wire 4 breaks.
As another embodiment, due to the tension applied to the wire 4 by the rise of the lower connecting plate 6, it is relatively difficult to synchronize with the fact that the two press blocks 5 also clamp the wire connection terminals, and especially, this mechanism is only for a single type of wire connection test of the wire 4, because the press blocks 5 clamp the wire connection terminals and the linkage relationship for pulling the wire 4 up in place is relatively unique, and therefore the limitation of the application is relatively large. In order to make it possible to adapt to experiments with mechanical properties of wiring of more types, as shown in fig. 3-4, the two ends of the worm 18 here must each be provided integrally with a section of connecting post 33, and then the connecting post 33 is rotatably mounted in a mounting seat 21, which in turn enables a rotational mounting of the worm 18. Specifically, the mounting seat 21 may be fixed at the bottom of the lower connecting plate 6, and the free end of the connecting post 33 is coaxially fixed with the bearing plate 22, where the end face size of the bearing plate 22 is larger than the end face size of the connecting post 33, that is, if the connecting post 33 is a standard cylindrical shape, the diameter of the bearing plate 22 is larger than the diameter of the connecting post 33 when the bearing plate 22 is a standard disc shape. On the basis of the above structure, as shown in fig. 4, it is also necessary to specially fix an annular connecting cover 25 at the end of the drive stud 20 facing the free end, i.e., the end facing the connecting post 33, and this connecting cover 25 is axially slidably fitted with a slide plate 24 and a disc spring 23, and a bearing plate 22 axially slidably fitted into the connecting cover 25. Finally, a plurality of locking bolts 27 screwed into the connecting cover 25 are arranged on the end face of the connecting cover 25 facing the drive stud 20 in a threaded fit manner, the locking bolts 27 are pressed and contacted on the sliding plate 24, the disc springs 23 are strongly compressed, the parts of the bearing plates 22 exposed out of the connecting posts 33 are firmly attached to the inner side walls of the connecting cover 25 to form an axial elastic extrusion connecting structure with certain elastic buffer effect, when the screw rod 8 rotates, the two pressing blocks 5 are mutually closed to clamp the connecting terminals of the lead wires 4, at the moment, the lower connecting plate 6 also has a longer vertical upward stroke to straighten the lead wires 4, and then a pulling test is carried out, therefore, the screw rod 8 still continues to rotate, because the connecting terminals are clamped, the two pressing blocks 5 cannot continue to be closed, relative slipping occurs to the constituent elements inside the axial elastic extrusion connecting structure, for example, the bearing plates 22 rotate relative to the drive stud 20 in the connecting cover 25, and further rotation of the screw rod 8 is not influenced, the screw rod 8 can continue to rotate, the lower connecting plate 6 can be lifted, and accordingly, the lead wires 4 can be kept to be slightly separated from the upper connecting posts 23 due to the fact that the axial reverse tension of the connecting posts 23 are always and the tension is not firmly clamped.
As another special design structure, the above-mentioned axial elastic compression connection structure should have different relative slip capacities for different experimental batches, in order to adjust this capacity, as shown in fig. 4, lock bolts 27 are annularly arranged around the driving studs 20, and, critically, nuts of the lock bolts 27 are processed into a structure of a cylindrical gear 28, and the lock bolts 27 are located at one end in the connection cover 25, all of which are rotatably mounted in the slide plate 24 as shown in fig. 4 so as not to be separated from the slide plate 24 all the time during rotation, and guide blocks 31 are fixed to side walls of the slide plate 24, and the guide blocks 31 are slidably mounted in the inner wall of the connection cover 25 in a direction parallel to the axial direction of the driving studs 20 so that the slide plate 24 always moves in a predetermined straight line direction parallel to the axis of the connection cover 25. Meanwhile, in this embodiment, a locking screw cap 26 is screwed on one end of the driving stud 20 at the outside of the connection cover 25, a through hole is formed in the center of the locking screw cap 26 shown in fig. 4 for the driving stud 20 to pass through, and the inner wall of the through hole is processed into a structure of an inner gear ring 29, so that the inner gear ring 29 is meshed with all cylindrical gears 28, and therefore, as long as the locking screw cap 26 rotates, all locking bolts 27 synchronously move axially, pressure is uniformly applied to the sliding plate 24, and stability of the whole overload slipping structure is maintained, which is why the sliding plate 24 always moves along a given straight line direction parallel to the axis of the connection cover 25, because the locking bolts 27 are difficult to axially position by screwing, but after the rotating fit structure shown in fig. 4 is provided, the locking bolts 27 can be axially positioned by rotating fit with the sliding plate 24, so that extrusion and pushing of each locking bolt 27 on the sliding plate 24 are consistent.
Since the locking screw cap 26 is screw-mounted on the connection cover 25, the locking screw cap 26 can be in a relatively fixed position during rotation, but in order to improve the stability of the locking screw cap 26, a resilient piece 30 which can be compressed is specially arranged between the locking screw cap 26 and the connection cover 25, and the resilient piece 30 is similar to a resilient pad in a bolt connection, but has larger elastic force to provide larger pretightening force, and since the inner gear ring 29 of the locking screw cap 26 is larger, the cylindrical gear 28 of the locking bolt 27 is smaller, the locking screw cap 26 slightly rotates by an angle, and the locking bolt 27 can rotate by a plurality of rings, so that the resilient piece 30 can be used for adapting axial deformation without using elastic elements with large deformation such as springs. In addition, in order to improve reliability, the disc springs 23 are provided in a plurality, and all the disc springs 23 are arranged concentrically with each other.
In order to improve reliability, as shown in fig. 4, the end surface of the bearing plate 22 near the connecting post 33 and the inner wall of the connecting cover 25 opposite to the end surface may be fixed with wear-resistant friction plates 32, and the two wear-resistant friction plates 32 are coaxially and closely contacted with each other to form a large friction binding force, and meanwhile, the wear-resistant friction plates are convenient to directly replace and maintain after being worn.
As shown in fig. 2 and 5, the rotary table 3 is a circular boss structure, a plurality of rolling bearings 34, which may be deep groove ball bearings, are disposed around the rotary table 3, the rolling bearings 34 are rotatably mounted on the carrier plate 2, and one side of each rolling bearing 34 is located above an annular step surface of the circular boss structure and is in rolling tangential contact with a side wall of an upper circular table of the circular boss structure, so that the rotary table 3 rotates more flexibly and stably. In order to drive the rotary table 3, this embodiment describes a simple and practical structure in which, as shown in fig. 2, an outer ring gear 35 is coaxially fixed to the bottom end of the rotary table 3, this outer ring gear 35 protrudes below the carrier plate 2, the outer ring gear 35 is meshed with a driving gear 36 through a reduction gear, the driving gear 36 is fixed to the main shaft of a speed-adjusting ac motor 12, the speed-adjusting ac motor 12 is fixed in the table frame 1, and the rotary table 3 is flexibly driven to rotate by the speed-adjusting ac motor 12.
The foregoing details of the specific embodiments are presented by way of example only and are not intended to limit the scope of the claimed invention, and one of ordinary skill in the art, upon understanding the foregoing embodiments, could simply devise variations which would still fall within the spirit of the claimed invention.
