Description

Technical Field

[0002] A servo-driven multi-directional composite tensile testing machine is a testing device that utilizes servo motor drive technology to achieve multi-directional composite tensile testing. It is widely used in materials mechanical property testing, product development, and quality control.

The servo motor can precisely control the tensile speed and force value, and combined with a closed-loop control system, it can achieve high-precision tensile testing.

[0003] Existing stretching machines typically only move up and down to stretch materials vertically, and can detect longitudinal stretching, but cannot reliably detect transverse stretching. To address this, we propose a servo-driven multi-directional composite stretching machine. Utility Model Content

[0033] The embodiments of this utility model will be further described below with reference to the accompanying drawings.

[0034] Example:

[0035] like Figures 1-5 As shown, a servo-driven multi-directional composite stretching machine includes:

[0036] Mounting base 1 has symmetrical connecting feet on the lower part of its front and rear surfaces; and symmetrical mounting guide grooves are opened on the top.

[0037] The lateral adjustment drive mechanism 2 is fixedly mounted on the top of the mounting base 1;

[0038] The longitudinal adjustment drive mechanism 3 is movably located inside the mounting guide groove at the top of the mounting base 1, and its rear surface is fixedly connected to the output end of the transverse adjustment drive mechanism 2.

[0039] The mounting base plate 4 is fixedly installed on the inner side of the longitudinal adjustment drive mechanism 3;

[0040] The clamping mechanism 5 is fixedly installed at the top center of the mounting base 1, at the bottom of the output end of the longitudinal adjustment drive mechanism 3, and on one side of the fixed mounting plate 4.

[0041] The working principle of the above technical solution is as follows:

[0042] During use, when the material is clamped and fixed by the clamping mechanism 5 at the top of the mounting base 1 and the bottom of the output end of the longitudinal adjustment drive mechanism 3, the longitudinal tension test of the material can be performed by the drive adjustment of the longitudinal adjustment drive mechanism 3. When the material is clamped and fixed by the clamping mechanism 5 on the surface of the fixed mounting plate 4, the transverse tension test of the material can be performed by the drive of the longitudinal adjustment drive mechanism 3 by the transverse adjustment drive mechanism 2. Thus, multi-directional tension test of the material can be performed, which is convenient to operate.

[0043] In another embodiment, such as Figure 2As shown, the longitudinal adjustment drive mechanism 3 includes a movable base 31 movably located inside the guide groove at the top of the mounting base 1. A connecting frame 32 is fixedly connected to the top of the movable base 31. A second fixed mounting plate 33 is fixedly connected to the inner side of the connecting frame 32. A second servo motor 34 is fixedly connected between the bottom end of the second fixed mounting plate 33 and the top end of the movable base 31. A movable threaded rod 35 is fixedly connected to the output end of the second servo motor 34. The top end of the movable threaded rod 35 passes through the inside of the top end of the connecting frame 32 and extends to the outside. A limiting top plate 36 is fixedly connected to the top end of the movable threaded rod 35. A self-adjusting mechanism 37 is threadedly connected to the outer surface of the limiting top plate 36.

[0044] The second servo motor 34 can drive the movable threaded rod 35 and the limiting top plate 36, so that the self-adjusting mechanism 37 can move inside the connecting frame 32 and outside the surface of the movable threaded rod 35 for adjustment. At the same time, when the lateral adjustment drive mechanism 2 is driven, the connecting frames 32 can move in opposite directions, so that the self-adjusting mechanism 37 can adjust itself by extension and retraction.

[0045] In another embodiment, such as Figure 2 As shown, the fixed mounting plate 4 is located inside the connecting frame 32, and the bottom end of the fixed mounting plate 4 is attached to one end of the top of the connecting frame 32.

[0046] The mounting base 4 is easy to fix and can be stably positioned inside the connecting frame 32 for use, making operation convenient.

[0047] In another embodiment, such as Figure 3 As shown, the self-adjusting mechanism 37 includes a movable mounting arm 371. A threaded through hole 372 is provided inside the end of the movable mounting arm 371. A movable mounting block 373 is movably connected inside the movable mounting arm 371. Rectangular guide grooves 374 are provided on both the front and rear surfaces of the movable mounting arm 371. Fixed connecting seats 375 are symmetrically provided on both the front and rear surfaces of the movable mounting arm 371. Fixed guide rods 376 are fixedly connected between the fixed connecting seats 375. A movable guide sleeve block 377 is movably connected to the outer surface of the fixed guide rod 376. A fastening bolt 378 is connected between the end of the movable guide sleeve block 377 and the outer surface of the movable mounting block 373.

[0048] When the connecting frames 32 move apart, they can drive the movable mounting arm 371 to move, so that the movable mounting block 373 can move inside the movable mounting arm 371. At the same time, the movable guide sleeve 377 can move inside the rectangular guide groove 374 and outside the surface of the fixed guide rod 376, thereby adjusting itself and making it convenient to use.

[0049] In another embodiment, such as Figure 3 As shown, the outer end of the movable guide sleeve 377 slides and fits against the inner side of the rectangular guide groove 374, and one of the clamping mechanisms 5 is located at the bottom center of the movable mounting block 373.

[0050] The movable guide sleeve 377 can move stably inside the rectangular guide groove 374 and outside the surface of the fixed guide rod 376, making operation convenient.

[0051] In another embodiment, such as Figure 4 As shown, the lateral adjustment drive mechanism 2 includes fixed mounting columns 21 symmetrically located at the top end of the mounting base 1. A first fixed mounting plate 22 is fixedly connected to the rear surface of the fixed mounting column 21. A first servo motor 23 is fixedly connected to one side of the first fixed mounting plate 22. A bidirectional threaded rod 24 is fixedly connected to the output end of the first servo motor 23. The outer surface of the bidirectional threaded rod 24 slides and fits against the interior of the first fixed mounting plate 22. A connecting moving block 25 is threadedly connected to the outer surface of the bidirectional threaded rod 24. One side of the connecting moving block 25 is fixedly connected to the rear surface of the connecting frame 32.

[0052] This facilitates the first servo motor 23 to drive the bidirectional threaded rod 24, so that when the bidirectional threaded rod 24 rotates, the connecting moving block 25 can move in opposite directions on the outer side of the surface of the bidirectional threaded rod 24, thereby driving the connecting frame 32 to move, which is convenient to operate.

[0053] In another embodiment, such as Figure 5 As shown, the clamping mechanism 5 includes a fixed mounting base 51, a fixed groove 52 is provided on the top of the fixed mounting base 51, and electric telescopic rods 53 are symmetrically provided on the front and rear surfaces of the fixed mounting base 51. The output end of the electric telescopic rod 53 passes through the interior of the fixed mounting base 51 and extends to the inner side of the fixed groove 52. The output end of the electric telescopic rod 53 is fixedly connected to a connecting clamping plate 54.

[0054] This allows the material end to be placed inside the fixing groove 52. Then, under the action of the electric telescopic rod 53, the connecting clamping plate 54 can be pushed, so that the connecting clamping plates 54 cooperate to clamp and fix the material end, making the operation convenient.

[0055] The working principle of this utility model is as follows: During use, the end of the material is placed inside the fixing groove 52 located at the top of the mounting base 1 and the bottom of the movable mounting block 373. Then, under the action of the electric telescopic rod 53, the connecting clamping plate 54 can be pushed, so that the connecting clamping plates 54 cooperate to clamp and fix the end of the material. At this time, the second servo motor 34 drives the movable threaded rod 35, so that the movable mounting arm 371 drives the movable mounting block 373 and the clamping mechanism 5 to move as a whole, thereby enabling longitudinal stretching of the material. If lateral stretching of the material is required, the end of the material is placed inside the fixing groove 52 located on one side of the fixed mounting base plate 4. Then, under the action of the electric telescopic rod 53, the connecting clamping plate 54 can be pushed, so that the connecting clamping plates 54 cooperate. The ends of the material are clamped and fixed. At this time, the first servo motor 23 drives the bidirectional threaded rod 24, so that when the bidirectional threaded rod 24 rotates, the connecting moving block 25 moves in opposite directions on the outer side of the surface of the bidirectional threaded rod 24, thereby driving the connecting frame 32 to move. When the connecting frame 32 moves, it can drive the movable mounting arm 371 to move, so that the movable mounting block 373 can move inside the movable mounting arm 371. At the same time, the movable guide sleeve 377 moves inside the rectangular guide groove 374 and outside the surface of the fixed guide rod 376, thereby adjusting its extension. At this time, the fixed mounting base plates 4 are separated from each other, and the clamping mechanisms 5 are separated, thereby performing lateral stretching of the material. The overall structure is simple and the operation is convenient and quick.

[0056] The above embodiments merely illustrate specific implementations of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model.
