DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative work fall within the scope of the present application.

[0021] In order to further understand the content of the present application, the present application will be described in detail with reference to the drawings.

[0022] In combination with Figure 1 A kind of field fixing device of drawing testing machine, including base plate 1, mounting plate 2 being arranged above base plate 1, and locking bolt 9 being movably connected to the outer surface of base plate 1, damping assembly 3 is arranged between base plate 1 and mounting plate 2.

[0023] The present application will be further described below in combination with embodiments.

[0024] Embodiment 1:

[0025] Please refer to Figures 1-5The damping assembly 3 comprises a fixed block 31 fixedly connected to the top end of the bottom plate 1, a sliding rod 32 fixedly connected to one side of the fixed block 31, a first sliding block 33 and a second sliding block 34 slidingly connected to the outer surface of the sliding rod 32, a first spring 35 fixedly connected between the first sliding block 33 and the second sliding block 34, a first connecting block 36 and a second connecting block 37 fixedly connected to the bottom end of the mounting plate 2, a first movable rod 38 movably connected between the first connecting block 36 and the first sliding block 33, and a second movable rod 39 movably connected between the second connecting block 37 and the second sliding block 34. The bottom plate 1 is the basis of the entire fixing device, and the mounting plate 2 is used to fix the pull testing machine. When the vibration is transmitted to the damping assembly 3, the first spring 35 is fixedly connected between the first sliding block 33 and the second sliding block 34, which facilitates the absorption and dispersion of vibration energy and reduces the vibration transmitted to the mounting plate 2, so as to facilitate the pull testing machine to remain stable in various working environments and reduce the influence of external and internal vibrations.

[0026] The top end of the connecting column 6 is fixedly connected with the first connecting plate 62, and the top end of the first connecting plate 62 is fixedly connected with the second spring 621 between the bottom end of the mounting plate 2. The second spring 621 provides an additional damping layer, which facilitates the further absorption and dispersion of vibration energy when the vibration is transmitted to the bottom plate 1, thereby reducing the vibration transmitted to the mounting plate 2.

[0027] The bottom end of the mounting plate 2 is fixedly connected with the L-shaped plate 7, the outer surface of the connecting column 6 is slidingly connected with the second connecting plate 61, the bottom end of the L-shaped plate 7 is in contact with the top end of the second connecting plate 61, and the bottom end of the second connecting plate 61 is fixedly connected with the third spring 611 between the top end of the bottom plate 1. When the vibration occurs, the slight shaking of the mounting plate 2 drives the L-shaped plate 7 to move, thereby driving the second connecting plate 61 to slide along the outer surface of the connecting column 6, and the third spring 611 facilitates the absorption and dispersion of vibration energy.

[0028] The fourth spring 71 is fixedly connected between the L-shaped plate 7 and the bottom end of the first connecting plate 62, and through the cooperation of the original damping assembly 3, the third spring 611 and the newly added fourth spring 71, a multi-level damping system is formed, which improves the overall damping effect

[0029] The mounting plate 2 has a first groove 21 and a second groove 22 at its top end. The first groove 21 and the second groove 22 are connected. A fixing component 4 is provided inside the second groove 22. The fixing component 4 includes a first threaded rod 41 rotatably connected to the inner wall of the second groove 22, a first bevel gear 42 fixedly connected to one end of the first threaded rod 41, a third slider 43 threadedly connected to the outer surface of the first threaded rod 41, and a first clamping plate 44 fixedly connected to the top end of the third slider 43. The first bevel gear 42 is located inside the first groove 21. When the first threaded rod 41 rotates, it drives the third slider 43 to move along the second groove 22, thereby driving the first clamping plate 44 to move, so that the first clamping plate 44 can clamp one side of the tensile testing machine.

[0030] The top of the mounting plate 2 has a third groove 23, which is connected to the first groove 21. The inner wall of the third groove 23 is rotatably connected to a second threaded rod 8. One end of the second threaded rod 8 is fixedly connected to a second bevel gear 81. The outer surface of the second threaded rod 8 is threadedly connected to a fourth slider 82. The top of the fourth slider 82 is fixedly connected to a second clamping plate 821. The second bevel gear 81 is located inside the first groove 21 and meshes with the first bevel gear 42. The rotation of the first threaded rod 41 drives the first bevel gear 42 to rotate, and the rotation of the first bevel gear 42 drives the second bevel gear 81 and the second threaded rod 8 to rotate, thereby driving the fourth slider 82 to move along the third groove 23. This facilitates the synchronous movement of the first clamping plate 44 and the second clamping plate 821, ensuring uniform clamping on both sides of the tensile testing machine.

[0031] A connecting rod 5 is fixedly connected to one end of the first threaded rod 41 away from the first bevel gear 42. A hand crank 51 is fixedly connected to one end of the connecting rod 5. The connecting rod 5 moves through the mounting plate 2. The first threaded rod 41 can be manually rotated directly through the hand crank 51, thereby driving the first bevel gear 42 and the second bevel gear 81 to rotate, so as to realize the synchronous control of the first clamping plate 44 and the second clamping plate 821.

[0032] In use, the pull testing machine is placed on the top end of the mounting plate 2, and the first threaded rod 41 is directly manually rotated through the shaking handle 51, the first threaded rod 41 drives the third sliding block 43 to move along the second groove 22 when rotating, thereby driving the first clamping plate 44 to move, the first threaded rod 41 rotates at the same time to drive the first bevel gear 42 to rotate, the first bevel gear 42 drives the second bevel gear 81 and the second threaded rod 8 to rotate, thereby driving the fourth sliding block 82 to move along the third groove 23, facilitating the synchronous movement of the first clamping plate 44 and the second clamping plate 821, so as to ensure the uniform clamping of both sides of the pull testing machine, when the vibration is transmitted to the damping assembly 3, the first spring 35 is fixedly connected between the first sliding block 33 and the second sliding block 34, facilitating the absorption and dispersion of vibration energy, reducing the vibration transmitted to the mounting plate 2, facilitating the pull testing machine to remain stable in various working environments, reducing the influence of external and internal vibration, and the second spring 621 provides an additional damping layer, through the original damping assembly 3, the third spring 611 and the newly added fourth spring 71, a multi-level damping system is formed, and the overall damping effect is improved.
