Description

Technical Field

[0001] This utility model belongs to the field of insulation product testing technology, and specifically relates to an insulation product testing device. Background Technology

[0002] Insulating rubber products are essential materials widely used in electrical, electronic, automotive, and aerospace fields. Their main advantages include high insulation, high temperature resistance, aging resistance, and corrosion resistance. Therefore, quality testing of insulating rubber products is crucial to ensure their reliability and safety in specific application environments.

[0003] A related technology (publication number CN215986336U) discloses an insulation testing device for industrial adhesive products, including a base plate and a movable rod. A base box is fixedly connected to the top of the base plate, and a testing platform is fixedly connected to the top of the base box. A fixed rod is fixedly connected to the left side of the top of the testing platform. Placement slots are formed on the top inner side of both the fixed rod and the movable rod. A screw is movably connected to the inner cavity of the placement slot via a bearing. A turntable is fixedly connected to the top of the screw. A threaded sleeve is threaded onto the surface of the screw, and a pressure plate is fixedly connected to the inner side of the threaded sleeve. This utility model incorporates a fixed rod, movable rod, threaded sleeve, second slider, second slide groove, screw, insertion hole, fixed plate, placement slot, insertion rod, pressure plate, turntable, electric telescopic rod, connecting rod, and connecting block. It solves the problem that existing insulation testing devices lack the function of clamping adhesive products during use, making them inconvenient for users.

[0004] The commonly used testing method for rubber products is the physical testing method, which includes tensile strength testing, compression set testing, and hardness testing. Tensile strength testing, in particular, involves stretching the insulating rubber product to measure its tensile strength and assess its mechanical properties. Conventional tensile strength testing of insulating products typically involves fixing one end of the rubber product and pulling the other end with an external force. However, because the tension is applied only to one end, the external force acting on both sides of the rubber product is difficult to distribute evenly throughout the stretching process. This results in uneven stress distribution during stretching, negatively impacting the accuracy of the tensile test results and preventing precise detection of the rubber product's true tensile properties. Utility Model Content

[0005] To address the problems of existing technologies that apply tension only to one end of a rubber product, resulting in uneven force distribution on both sides and thus uneven stress during stretching, which negatively impacts the accuracy of tensile testing results and prevents precise detection of the true tensile properties of the rubber product, this invention provides an insulating product testing device that simultaneously applies the same tensile force to both ends of the rubber product. This ensures consistent stress distribution on both ends during tensile testing, providing greater accuracy and more precise detection of the true tensile properties of the rubber product compared to single-sided tensile testing methods. The specific technical solution is as follows:

[0006] An insulating product testing device includes a base, on which two support arms are symmetrically arranged, and a mounting frame is installed between the two support arms. The mounting frame has a through cavity from top to bottom, and two swing plates are symmetrically rotatably arranged inside the mounting frame. The top ends of the two swing plates are connected to a positioning component, and the bottom ends of the two swing plates are connected through a driving component.

[0007] The drive assembly includes two first sliding grooves respectively opened at the bottom ends of the two swing plates. A drive rod is slidably disposed in the inner cavity of each first sliding groove. A drive plate is connected between the front ends of the two drive rods. A mounting plate is vertically mounted on the front side wall of the mounting bracket. A cylinder is mounted on the lower surface of the mounting plate. The output end of the cylinder is connected to the front side wall of the drive plate.

[0008] In the above technical solution, the two drive rods are symmetrically arranged with an outward tilt from front to back.

[0009] In the above technical solution, a guide assembly is provided between the mounting bracket and the drive plate;

[0010] The guide assembly includes a limiting block mounted on the drive plate. The limiting block has a limiting rod extending through it in the front-rear direction, and the rear end of the limiting rod is perpendicular to and fixedly connected to the front sidewall of the mounting frame.

[0011] In the above technical solution, each positioning component includes a second slide groove opened at the top of the swing plate. One end of a movable arm is rotatably connected to the second slide groove via a sliding pin. A positioning seat is vertically installed at the other end of the movable arm. A threaded rod is threadedly connected to the positioning seat in the vertical direction. A positioning piece is installed at one end of the threaded rod that extends into the inner cavity of the positioning seat.

[0012] In the above technical solution, the positioning piece is arranged parallel to the inner wall of the positioning seat.

[0013] In the above technical solution, a limiting seat is sleeved on the outer side of the mobile arm, and the limiting seat is fixedly connected to the mounting frame.

[0014] In the above technical solution, the positioning seat is U-shaped, and the U-shaped opening of the positioning seat is oriented towards the middle of the mounting bracket.

[0015] The insulating product testing device of this utility model has the following advantages compared with the prior art:

[0016] I. Addressing the problem that existing methods apply tension only to one end of a rubber product, making it difficult to achieve a balanced distribution of external force on both sides, resulting in uneven stress distribution during stretching and negatively impacting the accuracy of tensile testing results, thus hindering the precise detection of the true tensile properties of the rubber product, this invention addresses this issue. By rotating two sets of swing plates relative to each other, the positioning components used to position the rubber product move outwards simultaneously. This allows for the application of the same tensile force to both ends of the rubber product at the same time, ensuring consistent stress distribution on both sides during tensile testing. Compared to methods that apply tension only to one side, this method better guarantees the accuracy of tensile testing results and more precisely detects the true tensile properties of the rubber product.

[0017] Second, in this utility model, by setting a cylinder, a drive plate, and a drive rod, it is possible to drive the two sets of swing plates on the left and right sides to rotate synchronously with the same amplitude, unify the driving force, and ensure that the tension on the rubber product on the left and right sides is the same and equal, further ensuring that the rubber product is subjected to the same degree of tension on the left and right sides, and ensuring the accuracy of the test results.

[0018] Third, by setting a positioning seat, a threaded rod, and a positioning plate, this utility model can clamp and fix the end of the rubber product, ensuring that the rubber product will not detach during the stretching process, and completing the stretching test of the rubber product in one go, avoiding secondary positioning and stretching after detachment, which would affect the accuracy of the test results.

[0019] Fourth, this utility model can drive the swing plate to swing inward or outward by setting an inclined drive rod. The setting is simple and reasonable, which is conducive to the quick and effective detection of rubber products by humans.

[0020] In summary, this invention can simultaneously apply the same tensile force to both ends of a rubber product, ensuring that the forces on both ends are consistent during the tensile testing process. Compared to testing methods that apply tensile force to only one side, this invention can better guarantee the accuracy of the tensile test results, more accurately detect the true tensile properties of the rubber product, and ensure that the rubber product will not detach during the tensile process. It completes the tensile test of the rubber product in one go, avoiding secondary positioning and tensile testing after detachment, which would affect the accuracy of the test results.

Detailed Implementation

[0027] The following are specific implementation cases and appendices. Figures 1 to 5 The present invention will be further described below, but the present invention is not limited to these embodiments.

[0028] See Figures 1 to 5 As shown, an insulating product testing device includes a base 1, on which two support arms 2 are symmetrically arranged, and a mounting frame 3 is installed between the two support arms 2. The mounting frame 3 provides support for the installation of other components. The mounting frame 3 has a through cavity from top to bottom so that other components can rotate and move normally within the mounting frame 3. Two swing plates 4 are symmetrically arranged in the mounting frame 3 and rotated by pins. The top ends of the two swing plates 4 are connected to positioning components, and the bottom ends of the two swing plates 4 are connected by a drive component. The drive component enables the two swing plates 4 to rotate simultaneously to the middle or to the outside, thereby enabling the two sets of positioning components to move synchronously to the inside or to the outside. The two sets of positioning components moving to the outside can achieve tensile testing of the insulating product with the same tensile force at both ends.

[0029] Main references Figure 1 and Figure 2As shown, the driving assembly includes two first sliding grooves 5 respectively opened at the bottom ends of two swing plates 4. A driving rod 14 is slidably disposed through the inner cavity of each first sliding groove 5. A driving plate 13 is connected between the front ends of the two driving rods 14. A mounting plate 11 is vertically mounted on the front side wall of the mounting bracket 3. A cylinder 12 is mounted on the lower surface of the mounting plate 11. The output end of the cylinder 12 is connected to the front side wall of the driving plate 13. The opening of the cylinder 12 causes the driving plate 13 to move backward, so as to cause the two driving rods 14 to move backward along the inner cavity of the two first sliding grooves 5. Specifically, the two driving rods 14 are symmetrically arranged from front to back and outward. The first sliding grooves 5 are driven by the inclined driving rods 14, causing the bottom ends of the two swing plates 4 on both sides to rotate closer to the middle, so as to cause the top ends of the two swing plates 4 to gradually move away from the outside. That is, the two ends of the left and right positioning components and the insulating product move outward simultaneously for stretching.

[0030] In addition, the main references Figure 1 and Figure 2 As shown, a guide assembly is provided between the mounting frame 3 and the drive plate 13. The guide assembly includes a limiting block 15 mounted on the drive plate 13. A limiting rod 16 is provided through the limiting block 15 in the front-back direction. The rear end of the limiting rod 16 is perpendicular to and fixedly connected to the front side wall of the mounting frame 3. When the drive plate 13 is subjected to force and moves in the front-back direction, it causes the limiting block 15 to move back and forth along the limiting rod 16. That is, the limiting rod 16 can guide and limit the direction of the limiting block 15 and the drive plate 13, ensuring that the displacement of the drive plate 13 is always controlled in the front-back direction, so as to ensure that the drive rods 14 on the left and right sides are subjected to the same angle of driving force.

[0031] Main references Figure 3 As shown, each positioning assembly includes a second slide groove 17 at the top of the swing plate 4. One end of a movable arm 6 is rotatably connected to the second slide groove 17 via a sliding pin. Specifically, the sliding pin is slidably embedded in the second slide groove 17, and the movable arm 6 is rotatably connected to the sliding pin. A positioning seat 7 is vertically mounted on the other end of the movable arm 6. A threaded rod 8 is threadedly connected to the positioning seat 7 in the vertical direction. A positioning piece 9 is installed at one end of the threaded rod 8 that extends into the inner cavity of the positioning seat 7. The two ends of the insulating product to be tested are placed in the inner cavities of the two sets of positioning seats 7 respectively. By rotating the threaded rod 8, the ends of the insulating product are clamped and positioned between the positioning piece 9 and the inner wall of the positioning seat 7. Specifically, the positioning piece 9 is arranged parallel to the inner side wall of the positioning seat 7, thereby ensuring that the insulating product can be clamped and positioned to the maximum extent between the positioning piece 9 and the positioning seat 7.

[0032] In addition, a limiting seat 10 is sleeved on the outside of the movable arm 6, and the limiting seat 10 is fixedly connected to the mounting frame 3. Through the limiting seat 10, it can ensure that the second slide groove 17 drives the movable arm 6 to move normally, and at the same time, it can limit the movement direction of the movable arm 6 to the horizontal direction, so as to ensure that the insulating product after positioning in the positioning seat 7 is always subjected to horizontal tension.

[0033] Specifically, the positioning seat 7 is U-shaped, and the U-shaped opening of the positioning seat 7 faces the middle of the mounting frame 3, thereby ensuring that the insulating product can be placed into the positioning seat 7 from the U-shaped opening of the positioning seat 7, so as to achieve the clamping and positioning of the insulating product between the two positioning seats 7.

[0034] It is worth noting that in this application, the threaded rod 8 is a self-locking threaded rod 8 available on the market, which can self-lock when it stops rotating and will not be affected by external forces to rotate; the cylinder 12 is a cylinder with a self-locking function available on the market, whose output end can stay at any position and be locked. The model of the above-mentioned existing components will not be limited or described in detail.

[0035] The working principle of the insulating product testing device in this embodiment is as follows:

[0036] The two ends of the insulating product to be tested are placed in the inner cavities of the two sets of positioning seats 7 respectively. By rotating the threaded rod 8, the ends of the insulating product are clamped and positioned between the positioning plate 9 and the inner wall of the positioning seat 7. The activated cylinder 12 causes the drive plate 13 to move backward, so that the two drive rods 14 move backward along the inner cavities of the two first slide grooves 5. During this process, the first slide groove 5 is driven by the inclined drive rods 14, causing the bottom ends of the two swing plates 4 on both sides to rotate closer to the middle, so that the top ends of the two swing plates 4 gradually move away from the outside, causing the two moving arms 6 on both sides to move outward along the limiting seat 10, that is, causing the ends of the rubber products positioned in the left and right sets of positioning seats 7 to move outward. This allows the left and right ends of the positioned rubber products to be simultaneously subjected to an outward pulling force, thus realizing the detection of the tensile strength of the rubber products.

[0037] This invention can simultaneously apply the same tensile force to both ends of a rubber product outwards, ensuring that the force on both ends is consistent during the tensile testing of the rubber product. Compared with the testing method of applying tensile force to one side, it can better guarantee the accuracy of the tensile test results, more accurately detect the true tensile properties of the rubber product, and also ensure that the rubber product will not detach during the tensile process. It completes the tensile test of the rubber product in one go, avoiding secondary positioning and tensile testing after detachment, which would affect the accuracy of the test results.

[0038] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
