Description

Technical Field

[0001] This utility model relates to the field of fixture technology, and in particular to a membrane material testing fixture. Background Technology

[0002] Existing membrane material testing fixtures generally suffer from complex structures, leading to high usage and maintenance costs. Furthermore, these fixtures are not ideal for holding membrane materials in practical applications, causing the materials to easily detach during testing, thus affecting the accuracy and efficiency of the tests. Utility Model Content

[0003] The main objective of this invention is to provide a membrane material testing fixture to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A membrane material testing fixture includes a worktable. An upper clamping plate and a lower clamping plate are mounted on the worktable, with the lower clamping plate fixed to the upper surface of the worktable. Vertical clamping cylinders are fixed to the front and rear sides of the lower end of the worktable. The telescopic rods of the clamping cylinders slide through the worktable and the lower clamping plate, with the upper clamping plate fixed to the upper end of the telescopic rods. The lower clamping plate has a first and second bending section arranged side-by-side at its clamping opening, and the upper clamping plate has a third and fourth bending section arranged side-by-side at its clamping opening. The first and third bending sections are interlocked vertically, as are the second and fourth bending sections. Guide components are provided on the front and rear sides of both the upper and lower clamping plates.

[0006] Furthermore, a first horizontal transition section is provided between the first and second bending sections, and a second horizontal transition section is provided between the third and fourth bending sections. The lower end face of the second horizontal transition section is provided with an elongated protrusion, and the upper end face of the first horizontal transition section is provided with an elongated groove that engages with the elongated protrusion.

[0007] Furthermore, the cross-sections of the first, second, third, and fourth bending segments are all wavy, and each bending segment has a silicone layer on its surface.

[0008] Furthermore, the guide assembly consists of guide posts and guide holes. Vertical guide posts are fixed on both sides of the lower end of the upper clamping plate, and guide holes that cooperate with the guide posts on the same side are provided on the lower clamping plate.

[0009] Furthermore, the lower clamping plate is equipped with fixing feet at the four corners, and bolts are installed inside the fixing feet.

[0010] This invention also includes other components that enable the membrane material testing fixture to function properly. These devices or components all employ conventional techniques in the art. Furthermore, devices and components not specified in this invention all employ conventional techniques in the art, such as the clamping cylinder described in this application. In specific implementation, appropriate equipment or component models can be selected according to the specific working scenario.

[0011] The working principle of this invention is as follows: During operation, the membrane material to be clamped is placed at the clamping joint of the upper and lower clamping plates. Then, the clamping cylinder shortens, driving the upper and lower clamping plates to snap together. Because the cross-sections of the first, second, third, and fourth bending sections are all wavy, and each bending section has a silicone layer on its surface, this significantly increases the contact area with the membrane material and effectively increases the coefficient of friction, allowing the membrane material to be firmly clamped.

[0012] Furthermore, the elongated protrusion on the lower end face of the second horizontal transition section engages with the elongated groove on the upper end face of the first horizontal transition section, further enhancing the fixation effect of the membrane material and preventing it from falling off. Simultaneously, the guide posts and guide holes in the guide assembly cooperate to ensure precise alignment of the upper and lower clamping plates during the clamping process, thereby guaranteeing the stability and reliability of the fixture.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. Simplified structure and reduced cost: Compared with the existing technology, the membrane material testing fixture of this utility model has a simpler structure, which effectively reduces the cost of using and maintaining the equipment.

[0015] 2. Improved clamping effect: The wavy cross-section bending section and silicone layer, along with the interlocking elongated protrusions and grooves, significantly increase the contact area and friction coefficient with the membrane material, making the membrane material clamped more firmly and greatly reducing the risk of the membrane material falling off during testing.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0020] Example:

[0021] like Figures 1-2 As shown, a membrane material testing fixture includes a worktable 1. An upper clamping plate 3 and a lower clamping plate 2 are mounted on the worktable 1, with the lower clamping plate 2 fixed to the upper surface of the worktable 1. Vertical clamping cylinders 4 are fixed to the front and rear sides of the lower end of the worktable 1. The telescopic rods of the clamping cylinders 4 slide through the worktable 1 and the lower clamping plate 2, with the upper clamping plate 3 fixed to the upper end of the telescopic rods. A first bending section 21 and a second bending section 22 are arranged side-by-side at the clamping opening of the lower clamping plate 2, and a third bending section 31 and a fourth bending section 32 are arranged side-by-side at the clamping opening of the upper clamping plate 3. The first bending section 21 and the third bending section 31 are interlocked vertically, as are the second bending section 22 and the fourth bending section 32. Guide components are provided on the front and rear sides of both the upper clamping plate 3 and the lower clamping plate 2.

[0022] Specifically, the guiding components consist of guide posts 5 and guide holes. Vertical guide posts 5 are fixed on both sides of the lower end of the upper clamping plate 3, and guide holes that mate with the guide posts 5 on the same side are provided on the lower clamping plate 2. The cross-sections of the first bending segment 21, the second bending segment 22, the third bending segment 31, and the fourth bending segment 32 are all wavy, and each bending segment has a silicone layer 6 on its surface.

[0023] In addition, a first horizontal transition section 23 is provided between the first bending section 21 and the second bending section 22, and a second horizontal transition section 33 is provided between the third bending section 31 and the fourth bending section 32. The lower end face of the second horizontal transition section 33 has a long strip-shaped protrusion 34, and the upper end face of the first horizontal transition section 23 has a long strip-shaped groove 24 that engages with the long strip-shaped protrusion 34. The lower clamping plate 2 has fixing feet 7 at its four corners, and bolts 8 are installed inside the fixing feet 7.

[0024] The working principle of this membrane material testing fixture is as follows: During operation, the membrane material to be clamped is placed at the clamping joint of the upper clamping plate 3 and the lower clamping plate 2. Then, the clamping cylinder 4 shortens, driving the upper clamping plate 3 and the lower clamping plate 2 to snap together. Since the cross-sections of the first bending segment 21, the second bending segment 22, the third bending segment 31, and the fourth bending segment 32 are all wavy, and each bending segment has a silicone layer 6 on its surface, this significantly increases the contact area with the membrane material and effectively increases the coefficient of friction, allowing the membrane material to be firmly clamped.

[0025] Furthermore, the elongated protrusion 34 on the lower end face of the second horizontal transition section 33 engages with the elongated groove 24 on the upper end face of the first horizontal transition section 23, further enhancing the fixation effect of the membrane material and preventing it from falling off. At the same time, the guide post 5 and guide hole in the guide assembly cooperate with each other to ensure that the upper clamping plate 3 and the lower clamping plate 2 can be accurately aligned during the fastening process, thereby ensuring the stability and reliability of the fixture.

[0026] The above embodiments are merely descriptions of preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope of the present utility model.
