Description

Technical Field

[0001] This utility model relates to the field of material performance testing equipment, and in particular to a clamping device for testing the performance of energy-saving materials. Background Technology

[0002] Energy-saving materials are widely used in many fields such as construction and industry, making their performance testing crucial. Existing testing fixtures are mostly designed for conventional materials and have shortcomings when testing energy-saving materials. For example, the smooth surface of energy-saving materials makes it easy for samples to slip during tensile tests and other examinations using conventional fixtures, leading to data fluctuations or deviations and affecting the reliability of the test results. Existing fixtures also lack effective anti-slip measures. Utility Model Content

[0003] The purpose of this invention is to provide a clamping device for testing the performance of energy-saving materials. By setting an inclined guide structure, the two symmetrically distributed clamping heads are brought closer to each other by force, thereby achieving self-locking clamping and effectively preventing sample slippage. This solves the problem of sample slippage that easily occurs in conventional clamps in the prior art during tensile testing and other tests.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A clamping device for testing the performance of energy-saving materials includes two symmetrically distributed clamping arms. A locking assembly and a mounting assembly are installed between the lower ends of the two clamping arms. Two wedge-shaped symmetrically distributed clamping heads are installed between the upper ends of the two clamping arms. The clamping heads are slidably connected to the clamping arms located on the same side through an inclined guide structure. The inclined guide structure includes a first inclined surface disposed on the clamping arm and a second inclined surface disposed on the clamping head that abuts against and slides with the first inclined surface. The end of the clamping head away from the second inclined surface has a vertically distributed clamping plane. The second inclined surfaces on the two clamping heads form an acute angle with the opening facing downward.

[0006] Furthermore, a limiting baffle is provided on the inner side of the clamping arm, located below the clamping head on the same side.

[0007] Furthermore, at least one set of sliding groove and slider structure is provided between the clamping head and the clamping arm. The sliding groove and slider structure includes a T-shaped sliding groove provided on the first inclined surface and a T-shaped slider provided on the second inclined surface. The T-shaped sliding groove is vertically distributed along the first inclined surface, and the T-shaped slider is slidably connected with the T-shaped sliding groove.

[0008] Furthermore, an elastic reset component is provided between the clamping head and the clamping arm for pushing the clamping head to slide downward along the first inclined plane to reset.

[0009] Furthermore, the elastic reset assembly includes a first spring, a guide groove disposed on a first inclined surface, and a guide protrusion disposed on a second inclined surface. The guide groove is vertically distributed along the first inclined surface, the guide protrusion extends into the guide groove and is slidably connected to the guide groove, one end of the first spring abuts against the guide protrusion, and the other end of the first spring abuts against the upper end of the guide groove.

[0010] Furthermore, the clamping surface on the clamping head is fixed with an anti-slip pad.

[0011] Furthermore, the locking assembly includes a threaded rod and a guide post distributed in parallel. The threaded rod and the guide post are both distributed perpendicularly to the clamping arms. One end of the threaded rod and one end of the guide post are respectively fixedly connected to the inner side of one of the clamping arms. The other clamping arm is correspondingly provided with a first guide hole that slides with the threaded rod and a second guide hole that slides with the guide post. The free end of the threaded rod is threadedly connected to a locking cap for fixing the two clamping arms.

[0012] Furthermore, the end of the guide post is provided with a limiting block to prevent it from falling off.

[0013] Furthermore, the limiting block has a through stepped hole in the middle, the guide post has a threaded hole at its free end, and a fastener is connected between the stepped hole and the threaded hole.

[0014] Furthermore, the mounting assembly includes a connecting plate that is fitted to the guide post. The connecting plate has two second springs on its two sides that abut against clamping arms distributed on the same side. The two second springs are fitted onto the guide post. The connecting plate has through holes at both ends. The connecting plate is connected to the guide post through one of the through holes.

[0015] Compared with the prior art, this utility model provides a clamping device for testing the performance of energy-saving materials, which has the following beneficial effects:

[0016] This invention features a beveled guide structure between the clamping head and the clamping arm. When the sample is clamped using the two clamping heads and locked by the locking assembly, during tensile testing and other tests, the two clamping heads, guided by the bevel, tend to move closer together, thus automatically clamping the sample and ensuring a tighter grip. This self-locking function effectively prevents sample slippage. This invention offers good clamping performance, a simple structure, and convenient operation. Attached Figure Description

[0022] The technical solution of this utility model will be clearly and completely described below through detailed embodiments and in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0023] Please refer to Figures 1-3This embodiment provides a clamping device for testing the performance of energy-saving materials, including two symmetrically distributed clamping arms 1. A locking assembly 7 and a mounting assembly 8 are installed between the lower ends of the two clamping arms 1. Two wedge-shaped symmetrically distributed clamping heads 2 are installed between the upper ends of the two clamping arms 1. The clamping heads 2 are slidably connected to the clamping arms 1 located on the same side through an inclined guide structure 3. The inclined guide structure 3 includes a first inclined surface 31 disposed on the clamping arms 1 and a second inclined surface 32 disposed on the clamping heads 2 that abuts against and slides with the first inclined surface 31. The end of the clamping head 2 away from the second inclined surface 32 has a vertically distributed clamping plane 21. The second inclined surfaces 32 on the two clamping heads 2 form an acute angle with the opening facing downward. By setting an inclined guide structure between the clamping head and the clamping arm, when the sample is clamped by the two clamping heads and locked by the locking assembly, during the tensile test and other testing processes, the two clamping heads tend to move closer to each other under the guidance of the inclined surface, thus achieving the effect of automatically clamping the sample and making the sample clamped more tightly. This realizes the self-locking function of the sample and effectively prevents the sample from slipping.

[0024] As an example, the acute angle can preferably be set to 10°~50°, so as to have a better self-locking clamping force.

[0025] In some specific implementation methods, refer to Figure 1 and Figure 2 At least one set of sliding groove and slider structures is provided between the clamping head 2 and the clamping arm 1. The sliding groove and slider structure includes a T-shaped sliding groove 11 disposed on the first inclined surface 31 and a T-shaped slider 22 disposed on the second inclined surface 32. The T-shaped sliding groove 11 is vertically distributed along the first inclined surface 31, and the T-shaped slider 22 is slidably connected to the T-shaped sliding groove 11. In this way, the movement direction of the clamping head can be limited by the cooperation of the T-shaped sliding groove and the T-shaped slider, so that the clamping head can slide along the direction of the tensile force pulling the sample during the test.

[0026] As an improved implementation method, refer to Figure 2 and Figure 3An elastic reset assembly 5 is provided between the clamping head 2 and the clamping arm 1 for pushing the clamping head 2 to slide downwards and reset along the first inclined surface 31. Specifically, the elastic reset assembly 5 includes a first spring 51, a guide groove 52 disposed on the first inclined surface 31, and a guide protrusion 53 disposed on the second inclined surface 32. The guide groove 52 is vertically distributed along the first inclined surface 31, and the guide protrusion 53 extends into the guide groove 52 and is slidably connected to the guide groove 52. One end of the first spring 51 abuts against the guide protrusion 53, and the other end of the first spring 51 abuts against the upper end of the guide groove 52. Thus, during the test, since the guide protrusion and the first spring are in the guide groove, the clamping head is prevented from sliding upwards. At the same time, after the test is completed, it can slide downwards and reset under the restoring force of the first spring. As an example, the guide protrusion 53 is a cuboid protrusion. The guide protrusion 53 is fixedly connected to the second inclined surface 32 by screws.

[0027] In some specific implementation methods, refer to Figures 1-3 The inner side of the clamping arm 1 is provided with a limiting baffle 4 located below the clamping head 2 on the same side, so as to limit the clamping head in the non-detection working state and prevent it from sliding down. Specifically, as an example, the limiting baffle 4 is fixedly connected to the clamping arm 1 by two screws, and the limiting baffle 4 is horizontally distributed.

[0028] In some specific implementation methods, refer to Figures 1-3 An anti-slip pad 6 is fixed to the clamping plane 21 on the clamping head 2. This prevents excessive local compression of the energy-saving material sample during clamping, which could lead to material deformation and affect the accuracy of image detection. As an example, the anti-slip pad 6 can be a rubber sheet with an anti-slip structure on its surface.

[0029] In some specific implementation methods, refer to Figures 1-3 The locking assembly 7 includes parallel threaded rods 71 ​​and guide posts 72, both perpendicular to the clamping arms 1. One end of the threaded rod 71 and one end of the guide post 72 are fixedly connected to the inner side of one of the clamping arms 1, respectively. The other clamping arm 1 is correspondingly provided with a first guide hole 12 that slides with the threaded rod 71 and a second guide hole 13 that slides with the guide post 72. The free end of the threaded rod 71 is threadedly connected to a locking cap 73 for fixing the two clamping arms 1. By turning the locking cap, under the guidance of the guide post and the second guide hole, and under the action of the threaded rod and the first guide hole, the two clamping arms can be driven to clamp the two clamping heads, thereby allowing the two clamping heads to clamp the sample. The threaded connection provides a certain degree of self-locking capability, making it difficult to loosen.

[0030] As an example, such as Figure 2 and Figure 3 As shown, the threaded rod 71 and the guide post 72 are fixedly connected to the clamping arm 1 by screws.

[0031] As an improved implementation method, refer to Figures 1-3 The end of the guide post 72 is provided with a limiting block 74 to prevent it from falling off. As an example, the limiting block 74 is disc-shaped, and the diameter of the limiting block 74 is larger than the diameter of the second guide hole 13.

[0032] In some specific implementation methods, such as Figure 2 and Figure 3 As shown, the limiting block 74 has a through stepped hole in the middle, and the free end of the guide post 72 has a threaded hole. A fastener 75 connects the stepped hole and the threaded hole. As an example, the fastener 75 is a screw.

[0033] In some specific implementation methods, refer to Figures 1-3 The mounting assembly 8 includes a connecting plate 81 that is fitted onto the guide post 72. Two second springs 9 are respectively provided on both sides of the connecting plate 81, abutting against clamping arms 1 distributed on the same side. The two second springs 9 are fitted onto the guide post 72. Through holes 82 are respectively opened at both ends of the connecting plate 81, and the connecting plate 81 is connected to the guide post 72 through one of the through holes 82. In this way, testing equipment such as a tensile testing machine can be installed using the through holes on the connecting plate, and then the performance of the energy-saving material samples can be tested. Furthermore, by installing a second spring on each side of the connecting plate, the force can be balanced, ensuring that the connecting plate is centrally located.

[0034] In use, the clamping devices are used in pairs, such as... Figure 1 and Figure 3 As shown, the two clamping devices are connected to the upper and lower testing connectors of the testing equipment respectively through the through holes 82 on the connecting plate 81. Then, the clamping end of the sample 10 is placed in the center between the two clamping heads 2, and the locking cap 73 is turned to retract the two clamping arms 1 until the two clamping heads 2 clamp the sample 10 tightly and prevent it from loosening, thus completing the clamping installation of both ends of the sample. During the tensile test, the two clamping heads 2 tend to move closer to each other under the guidance of the inclined plane, thus achieving an automatic clamping effect on the sample, making the sample clamped more tightly and effectively preventing the sample from slipping. After the test is completed, the sample can be quickly released and removed simply by loosening the locking cap 73.

[0035] The above embodiments are merely illustrative of the concept and technical solution of this utility model, and are not intended to limit this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.

[0036] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
