Description

Technical Field

[0001] This invention relates to the field of silicone processing equipment, and in particular to a silicone product tensile and compressive testing device. Background Technology

[0002] Silicone has excellent weather resistance, low-temperature resistance, and is environmentally friendly, non-toxic, and easy to clean, making it commonly used to manufacture various household and industrial products. After silicone products are manufactured, their tensile and compressive strength needs to be tested to ensure that the products meet the corresponding quality requirements. Currently, the equipment for testing the tensile and compressive strength of silicone products is independent. For example, patent document CN213239727U discloses a device for testing the tensile strength of thermally conductive silicone sheets, which is only used to test the tensile strength of silicone products; patent document CN217006700U discloses a performance testing device for conductive silicone products, which is only used to test the compressive strength of silicone products.

[0003] It is evident that testing the tensile and compressive strength of silicone products requires the use of appropriate tensile and compressive testing equipment. The testing process necessitates multiple transfers, conveying, and clamping of the silicone products, which undoubtedly increases the time consumed in the testing process.

[0004] Based on this, the present invention provides a silicone product tensile and compressive integrated testing device to eliminate the transfer and transportation links and repeated clamping operations of silicone products in tensile and compressive testing, thereby effectively improving the efficiency of testing the tensile and compressive strength of silicone products. Summary of the Invention

[0005] Based on this, the present invention provides a silicone product tensile and compressive testing device, including a frame, on which a slide bar assembly is provided. The slide bar assembly includes several vertically arranged slide bars, and two clamping assemblies are slidably arranged vertically on the slide bar assembly. The two clamping assemblies are arranged vertically and are respectively drivenly connected to a first driving device provided on the frame. The first driving device is used to drive the clamping assemblies driven to it to move vertically along the slide bar assembly. Each clamping assembly includes a first mounting strip and a second mounting strip arranged front to back, both of which are arranged in a left-right direction. The first mounting strip has a plurality of first mounting holes extending through it in the front-to-back direction. The first mounting holes are arranged sequentially in the left-to-right direction. The second mounting strip has a plurality of second mounting holes corresponding to the first mounting holes, and the second mounting holes are coaxially arranged with their corresponding first mounting holes. A first clamping rod and a second clamping rod are respectively slidably disposed in the first mounting holes and the second mounting holes. The frame is also provided with a flat pushing mechanism corresponding to the first clamping rod and the second clamping rod for pushing the first clamping rod and the second clamping rod toward the inside of the clamping assembly.

[0006] In this invention, two clamping components slidably mounted on a slide bar assembly are used to clamp silicone products. After the two clamping components clamp the two ends of the silicone product, the two clamping components are driven to move towards or away from each other by a first driving device, thereby achieving the pulling and compression of the silicone product. That is, this invention can realize the compression test of silicone products on a single device, and can eliminate the transfer and transportation links and repeated clamping operations when performing tensile and compression tests on silicone products, thereby effectively improving the testing efficiency of silicone products during tensile and compression tests.

[0007] In this invention, the clamping process for the silicone product is as follows: the silicone product is placed between the first and second mounting strips. Then, a flat-pushing mechanism is used to move the first and second clamping rods toward the inside of the clamping assembly. At this time, the first and second clamping rods will press against the surface of the silicone product, thereby achieving the clamping operation. If the silicone product is irregularly shaped, the moving distance of each clamping rod can be different to ensure that each clamping rod presses against the surface of the silicone product, achieving good fixation. Therefore, this invention can be used for clamping and fixing silicone products of various shapes, exhibiting good adaptability.

[0008] In addition, when the silicone product is irregularly shaped, the first and second clamping rods can be pressed against the silicone product, so that the first and second clamping rods are pressed against the recessed part of the silicone product, making the clamping assembly more secure in clamping and fixing the silicone product.

[0009] Furthermore, the first clamping rod is also provided with two first blocking blocks, which are respectively located on the front and rear sides of the first mounting strip. The second clamping rod is also provided with two second blocking blocks, which are respectively located on the front and rear sides of the second mounting strip.

[0010] In this invention, the first blocking block on the first clamping rod and the second blocking block on the second clamping rod are located on the front and rear sides of the first mounting strip and the front and rear sides of the second mounting strip, respectively, which can effectively prevent the first clamping rod and the second clamping rod from detaching from the first mounting strip and the second mounting strip during movement.

[0011] Furthermore, the first mounting strip and the second mounting strip in the clamping assembly are fixedly connected to each other by a connecting rod.

[0012] In this invention, the first mounting strip and the second mounting strip are fixedly connected to each other, which can improve the overall structural strength of the clamping assembly. At the same time, it can ensure that the first mounting strip and the second mounting strip can move up and down in strict synchronization, thereby improving the accuracy of the stretching and compressing direction of the silicone product.

[0013] Furthermore, the flat-pushing mechanism corresponding to the first clamping rod and the second clamping rod is located on the front side of the first clamping rod and the rear side of the second clamping rod, respectively. The flat-pushing mechanism includes a third mounting strip, on which a third mounting hole is opened corresponding to the first clamping rod or the second clamping rod. The third mounting hole is coaxially arranged with the corresponding first clamping rod or the second clamping rod. A top rod can also be slidably arranged in the third mounting hole. Both ends of the top rod extend out of the third mounting hole, and a cylindrical spring is sleeved on the end of the top rod away from the clamping assembly. The top end of the top rod is connected to the third mounting strip through the cylindrical spring sleeved thereon. A second driving device is also provided on the frame corresponding to the third mounting strip and driven to move the third mounting strip back and forth.

[0014] In this invention, the second driving device drives the third mounting strip to move toward the clamping assembly, thereby enabling the push rods on the third mounting strip to move toward the first and second clamping rods until the push rods abut against the corresponding first and second clamping rods. At this point, as the third mounting strip continues to move, each of the first and second clamping rods will gradually press against the surface of the silicone product. After the first and second clamping rods press against the surface of the silicone product, the corresponding push rods that cannot continue to move toward the clamping assembly will compress their cylindrical springs, allowing the third mounting strip to continue moving toward the clamping assembly, ensuring that ultimately all the first and second clamping rods are pressed against the silicone product.

[0015] Furthermore, the upper surface of the first mounting strip has a first fixing hole corresponding to the first mounting hole, and the first fixing hole is connected to the corresponding first mounting hole. The upper surface of the first mounting strip can also be movably provided with a first pressure plate. The lower surface of the first pressure plate has a first pressure rod corresponding to the first fixing hole, and the first pressure rod is inserted into the corresponding first fixing hole. The upper surface of the second mounting strip has a second fixing hole corresponding to the second mounting hole, and the second fixing hole is connected to the corresponding second mounting hole. The upper surface of the second mounting strip can also be movably provided with a second pressure plate. The lower surface of the second pressure plate has a second pressure rod corresponding to the first fixing hole, and the second pressure rod is inserted into the corresponding second fixing hole.

[0016] In this invention, after all the first and second clamping rods are pressed against the silicone product, the first and second pressure plates are moved down to press the first and second pressure rods against the corresponding first and second clamping rods, thus fixing their positions. This ensures that the first and second clamping rods remain pressed against the silicone product. Even if the first and second mounting strips move up and down, causing the first and second clamping rods to move away from their corresponding top rods, the first and second clamping rods will still remain pressed against the silicone product, achieving continuous clamping and fixing of the silicone product by the first and second clamping rods.

[0017] Furthermore, at least two first mounting rods are provided on the upper surface of the first mounting strip corresponding to the first pressure plate. The first pressure plate is slidably fitted onto the first mounting rods, and a cylindrical spring is fitted onto the portion of the first mounting rod above the first pressure plate. The top end of the first mounting rod is connected to the upper surface of the first pressure plate through the cylindrical spring fitted onto it. A third driving device is also provided on the first mounting strip corresponding to the first pressure plate and driven to drive the first pressure plate to move up and down along the first mounting rod. At least two second mounting rods are provided on the upper surface of the second mounting strip corresponding to the second pressure plate. The second pressure plate is slidably fitted onto the second mounting rods, and a cylindrical spring is fitted onto the portion of the second mounting rod above the second pressure plate. The top end of the second mounting rod is connected to the upper surface of the second pressure plate through the cylindrical spring fitted onto it. A fourth driving device is also provided on the second mounting strip corresponding to the second pressure plate and driven to drive the second pressure plate to move up and down along the second mounting rod.

[0018] In this invention, the third and fourth driving devices are used to drive the first and second pressure plates to move up and down. If it is necessary to fix the position of the first and second clamping rods, the driving of the third and fourth driving devices on the first and second pressure plates is released, so that the cylindrical springs on the first and second mounting rods press down on the first and second pressure plates. At this time, the first and second pressing rods on the first and second pressure plates can fix the first and second clamping rods in the first and second mounting strips. If it is necessary to move the position of the first and second clamping rods, the third and fourth driving devices are used to lift the first and second pressure plates, so as to release the fixation of the first and second clamping rods in the first and second mounting strips by the first and second pressing rods on the first and second pressure plates.

[0019] Furthermore, the first drive device, the second drive device, the third drive device, and the fourth drive device are all drive cylinders or drive hydraulic cylinders.

[0020] Furthermore, the top rod is provided with a first magnetic part at one end facing the clamping assembly, and the first clamping rod and the second clamping rod are provided with a second magnetic part corresponding to the first magnetic part on the top rod for magnetic attraction with the first magnetic part.

[0021] In this invention, when it is necessary to change the silicone product held by the clamping assembly, the third mounting strip drives the top rod on it to move toward the clamping assembly, so that the first magnetic part on the top rod abuts against the second magnetic parts on all the first and second clamping rods. Then, the third mounting strip moves away from the clamping assembly, so that the first and second clamping rods move away from the middle position of the clamping assembly, releasing the fixation on the silicone product. At the same time, the gap between the first and second clamping rods is widened, which makes it easier to put the silicone product in.

[0022] Furthermore, the first clamping rod has an insertion post at one end facing the second clamping rod, and the second clamping rod has a slot for inserting the insertion post at one end facing the first clamping rod.

[0023] In this invention, by moving the first clamping rod and the second clamping rod toward each other, the insertion post on the first clamping rod can be inserted into the corresponding slot, thereby making each first clamping rod and each second clamping rod dock together to form a plate-like structure. At this time, by moving the plate-like structure on the two clamping components toward each other, this invention can test the compressive strength of silicone products that cannot be clamped using clamping components, such as silicone products with spherical or ellipsoidal shapes and arc-shaped surfaces with smooth transitions.

[0024] Furthermore, both the first clamping rod and the second clamping rod are square rods, and the first mounting hole and the second mounting hole are square holes that match the first clamping rod and the second clamping rod, respectively.

[0025] In this invention, the square-shaped first clamping rod and the second clamping rod cannot rotate in the square-shaped first mounting hole and the second mounting hole, thereby effectively preventing the first clamping rod and the second clamping rod from rotating relative to the silicone product, thus preventing the clamping ability of the first clamping rod and the second clamping rod from weakening due to rotation.

[0026] The principles and effects of the present invention will be further explained below with reference to the above technical solutions and accompanying drawings:

[0027] In this invention, two clamping components slidably mounted on a slide bar assembly are used to clamp silicone products. After the two clamping components clamp the two ends of the silicone product, the two clamping components are driven to move towards or away from each other by a first driving device, thereby achieving the pulling and compression of the silicone product. That is, this invention can realize the compression test of silicone products on a single device, and can eliminate the transfer and transportation links and repeated clamping operations when performing tensile and compression tests on silicone products, thereby effectively improving the testing efficiency of silicone products during tensile and compression tests.

Detailed Implementation

[0035] To facilitate understanding by those skilled in the art, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments:

[0036] like Figure 1-5A silicone product tensile and compressive testing device includes a frame 1. The frame 1 has a set of slide rods 11, each set comprising several vertically arranged slide rods 11. Two clamping assemblies are slidably mounted on each set of slide rods 11, positioned vertically. Each clamping assembly is connected to a first driving device 12 mounted on the frame 1. The first driving device 12 drives the clamping assembly connected to it to move vertically along the set of slide rods 11. Each clamping assembly includes a first mounting strip 21 and a second mounting strip 22 arranged front-to-back. Both the first mounting strip 21 and the second mounting strip 22 are arranged in a left-right direction. The mounting strip 21 has several first mounting holes that extend through it in the front-to-back direction. The first mounting holes are arranged sequentially in the left-to-right direction. The second mounting strip 22 has several second mounting holes corresponding to the first mounting holes, and the second mounting holes are coaxially arranged with their corresponding first mounting holes. A first clamping rod 211 and a second clamping rod 221 are respectively slidably disposed in the first mounting hole and the second mounting hole. The frame 1 is also provided with a flat pushing mechanism corresponding to the first clamping rod 211 and the second clamping rod 221 for pushing the first clamping rod 211 and the second clamping rod 221 toward the inside of the clamping assembly.

[0037] In this invention, two clamping components slidably mounted on the slide rod 11 are used to clamp the silicone product. After the two clamping components clamp the two ends of the silicone product, the first driving device 12 drives the two clamping components to move towards or away from each other, thereby achieving the pulling and compression of the silicone product. That is, this invention can realize the compression test of silicone products on a single device, and can eliminate the transfer and transportation links and repeated clamping operations when performing tensile and compression tests on silicone products, thereby effectively improving the testing efficiency of silicone products during tensile and compression tests.

[0038] In this invention, the clamping operation of the clamping assembly for silicone products is as follows: the silicone product is placed between the first mounting strip 21 and the second mounting strip 22. Then, a flat-pushing mechanism is used to push the first clamping rod 211 and the second clamping rod 221 toward the inside of the clamping assembly. At this time, the first clamping rod 211 and the second clamping rod 221 will press against the surface of the silicone product, thereby achieving the clamping operation of the silicone product. If the silicone product is irregularly shaped, the moving distance of each first clamping rod 211 and each second clamping rod 221 can be different when moving toward the silicone product, so that each first clamping rod 211 and each second clamping rod 221 can press against the surface of the silicone product, achieving good fixation of the silicone product. That is, this invention can be used for clamping and fixing silicone products of various shapes and has good adaptability.

[0039] In addition, when the silicone product is irregularly shaped, the first clamping rod 211 and the second clamping rod 221 can be pressed against the silicone product, so that the first clamping rod 211 and the second clamping rod 221 are pressed against the recessed part of the silicone product, so that the clamping assembly can more firmly clamp and fix the silicone product.

[0040] In one embodiment, the first clamping rod 211 is further provided with two first blocking blocks 2111, which are respectively located on the front and rear sides of the first mounting strip 21. The second clamping rod 221 is further provided with two second blocking blocks 2211, which are respectively located on the front and rear sides of the second mounting strip 22.

[0041] In this embodiment, the first blocking block 2111 on the first clamping rod 211 and the second blocking block 2211 on the second clamping rod 221 are located on the front and rear sides of the first mounting strip 21 and the front and rear sides of the second mounting strip 22, respectively, which can effectively prevent the first clamping rod 211 and the second clamping rod 221 from detaching from the first mounting strip 21 and the second mounting strip 22 during the movement.

[0042] In one embodiment, the first mounting strip 21 and the second mounting strip 22 in the clamping assembly are fixedly connected to each other by a connecting rod 23.

[0043] In this embodiment, the first mounting strip 21 and the second mounting strip 22 are fixedly connected to each other, which can improve the overall structural strength of the clamping assembly. At the same time, it can ensure that the first mounting strip 21 and the second mounting strip 22 can move up and down in strict synchronization, thereby improving the accuracy of the stretching and pressing direction of the silicone product.

[0044] In one embodiment, a pushing mechanism corresponding to the first clamping rod 211 and the second clamping rod 221 is located on the front side of the first clamping rod 211 and the rear side of the second clamping rod 221, respectively. The pushing mechanism includes a third mounting strip 31, on which a third mounting hole is provided corresponding to the first clamping rod 211 or the second clamping rod 221. The third mounting hole is coaxially arranged with the corresponding first clamping rod 211 or the second clamping rod 221. A top rod 32 can also be slidably arranged in the third mounting hole. Both ends of the top rod 32 extend out of the third mounting hole, and a cylindrical spring 5 is sleeved on the end of the top rod 32 away from the clamping assembly. The top end of the top rod 32 is connected to the third mounting strip 31 through the cylindrical spring 5 sleeved thereon. A second driving device 33 is also provided on the frame 1 corresponding to the third mounting strip 31 and drivenly connected to the third mounting strip 31 to drive the third mounting strip 31 to move back and forth.

[0045] In this embodiment, the second driving device 33 drives the third mounting strip 31 to move toward the clamping assembly, thereby enabling the push rod 32 on the third mounting strip 31 to move toward the first clamping rod 211 and the second clamping rod 221 until the push rod 32 abuts against the corresponding first clamping rod 211 and second clamping rod 221. At this time, as the third mounting strip 31 continues to move, each first clamping rod 211 and each second clamping rod 221 will gradually press against the surface of the silicone product. After the first clamping rod 211 and the second clamping rod 221 press against the surface of the silicone product, the corresponding push rod 32 that cannot continue to move toward the clamping assembly will compress the cylindrical spring 5 on it, so that the third mounting strip 31 can continue to move toward the clamping assembly, ensuring that all the first clamping rods 211 and the second clamping rods 221 can eventually press against the silicone product.

[0046] In one embodiment, the upper surface of the first mounting strip 21 has a first fixing hole corresponding to the first mounting hole, and the first fixing hole is connected to the corresponding first mounting hole. The upper surface of the first mounting strip 21 can also be movably provided with a first pressure plate 212, and the lower surface of the first pressure plate 212 has a first pressure rod 213 corresponding to the first fixing hole, which is inserted into the corresponding first fixing hole. The upper surface of the second mounting strip 22 has a second fixing hole corresponding to the second mounting hole, and the second fixing hole is connected to the corresponding second mounting hole. The upper surface of the second mounting strip 22 can also be movably provided with a second pressure plate, and the lower surface of the second pressure plate has a second pressure rod corresponding to the first fixing hole, which is inserted into the corresponding second fixing hole.

[0047] In this embodiment, after all the first clamping rods 211 and the second clamping rods 221 are pressed against the silicone product, the first pressure plate 212 and the second pressure plate are moved down to press the first pressure rod 213 and the second pressure rod against the corresponding first clamping rod 211 and the second clamping rod 221, thus fixing the position of the first clamping rod 211 and the second clamping rod 221 so that the first clamping rod 211 and the second clamping rod 221 can always be pressed against the silicone product. At this time, even if the first mounting strip 21 and the second mounting strip 22 move up and down, causing the first clamping rod 211 and the second clamping rod 221 to move away from the corresponding top rod 32, the first clamping rod 211 and the second clamping rod 221 can still be pressed against the silicone product, realizing the continuous clamping and fixing of the first clamping rod 211 and the second clamping rod 221 against the silicone product.

[0048] In one embodiment, at least two first mounting rods 214 are provided on the upper surface of the first mounting strip 21 corresponding to the first pressure plate 212. The first pressure plate 212 is slidably sleeved on the first mounting rods 214, and a cylindrical spring 5 is sleeved on the portion of the first mounting rod 214 above the first pressure plate 212. The top end of the first mounting rod 214 is connected to the upper surface of the first pressure plate 212 through the cylindrical spring 5 sleeved on it. A third driving device is also provided on the first mounting strip 21 corresponding to the first pressure plate 212 and drivenly connected to the first pressure plate 212 to drive the first mounting rod 21. The first pressure plate 212 moves up and down along the first mounting rod 214; the upper surface of the second mounting strip 22 is provided with at least two second mounting rods corresponding to the second pressure plate, the second pressure plate is slidably sleeved on the second mounting rods, and the portion of the second mounting rod above the second pressure plate is sleeved with a cylindrical spring 5, the top end of the second mounting rod is connected to the upper surface of the second pressure plate through the cylindrical spring 5 sleeved on it, and the second mounting strip 22 is also provided with a fourth driving device corresponding to the second pressure plate and driven to drive the second pressure plate to move up and down along the second mounting rod;

[0049] In this embodiment, the third and fourth driving devices are used to drive the first pressure plate 212 and the second pressure plate to move up and down. If it is necessary to fix the position of the first clamping rod 211 and the second clamping rod 221, the driving of the first pressure plate 212 and the second pressure plate by the third and fourth driving devices is released, so that the cylindrical springs 5 ​​on the first mounting rod 214 and the second mounting rod press down on the first pressure plate 212 and the second pressure plate. At this time, the first pressing rod 213 and the second pressing rod on the first pressure plate 212 and the second pressure plate can fix the first clamping rod 211 and the second clamping rod 221 in the first mounting strip 21 and the second mounting strip 22. If it is necessary to move the position of the first clamping rod 211 and the second clamping rod 221, the first pressure plate 212 and the second pressure plate are lifted by the third and fourth driving devices, so as to release the fixation of the first clamping rod 211 and the second clamping rod 221 in the first mounting strip 21 and the second mounting strip 22 by the first pressing rod 213 and the second pressing rod on the first pressure plate 212 and the second pressure plate.

[0050] In one embodiment, the first drive device 12, the second drive device 33, the third drive device, and the fourth drive device are all drive cylinders or drive hydraulic cylinders.

[0051] In one embodiment, the top rod 32 is provided with a first magnetic part 321 at one end facing the clamping assembly, and the first clamping rod 211 and the second clamping rod 221 are provided with a second magnetic part 4 corresponding to the first magnetic part 321 on the top rod 32 for magnetic attraction with the first magnetic part 321.

[0052] In this embodiment, when it is necessary to change the silicone product held by the clamping assembly, the third mounting strip 31 drives the top rod 32 on it to move toward the clamping assembly, so that the first magnetic part 321 on the top rod 32 abuts against the second magnetic parts 4 on all the first clamping rods 211 and the second clamping rods 221. Then, the third mounting strip 31 moves away from the clamping assembly, so that the first clamping rods 211 and the second clamping rods 221 move away from the middle position of the clamping assembly, releasing the fixation on the silicone product. At the same time, the gap between the first clamping rods 211 and the second clamping rods 221 is widened, which makes it easier to put the silicone product in.

[0053] In one embodiment, the first clamping rod 211 has an insertion post 2112 at one end facing the second clamping rod 221, and the second clamping rod 221 has a slot 2212 for inserting the insertion post 2112 at one end facing the first clamping rod 211.

[0054] In this embodiment, by moving the first clamping rod 211 and the second clamping rod 221 toward each other, the insertion post 2112 on the first clamping rod 211 can be inserted into the corresponding slot 2212, thereby making each first clamping rod 211 and each second clamping rod 221 dock with each other to form a plate-like structure. At this time, by moving the plate-like structures on the two clamping components toward each other, the present invention can test the compressive strength of silicone products that cannot be clamped using clamping components, such as silicone products with spherical or ellipsoidal shapes and arc-shaped and smooth transition surfaces.

[0055] In one embodiment, both the first clamping rod 211 and the second clamping rod 221 are square rods, and the first mounting hole and the second mounting hole are square holes that match the first clamping rod 211 and the second clamping rod 221, respectively.

[0056] In this embodiment, the square-shaped first clamping rod 211 and the second clamping rod 221 cannot rotate in the square-shaped first mounting hole and the second mounting hole, thereby effectively preventing the first clamping rod 211 and the second clamping rod 221 from rotating relative to the silicone product, thus preventing the clamping ability of the first clamping rod 211 and the second clamping rod 221 from weakening due to rotation.

[0057] The above embodiments merely illustrate several implementation methods of the present invention, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the invention patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention. Therefore, the protection scope of this invention patent should be determined by the appended claims.
