Description

Technical Field

[0001] This utility model belongs to the field of carbon fiber material testing technology, and in particular relates to a carbon fiber material strength testing device. Background Technology

[0002] Carbon fiber strength testing refers to the process of measuring and evaluating the maximum load-bearing capacity of carbon fiber materials under different stress conditions (such as tension, compression, and bending) using specialized testing methods and equipment. This testing aims to determine the mechanical properties, structural integrity, and application reliability of carbon fiber materials, providing crucial information for material selection, product design, and quality control. As the most important part of the testing process, the requirements for carbon fiber strength testing equipment are becoming increasingly stringent.

[0003] However, existing carbon fiber material strength testing equipment, although it achieves its intended purpose through simple component assembly, suffers from a lack of protective devices due to the large output force required for strength testing. This makes it highly susceptible to injury to testing personnel. Furthermore, the use of a threaded rod moving structure in the device results in significant wear on the threaded rod, reducing the service life of critical components.

[0004] To address the aforementioned issues, a search revealed that patent CN217586679U discloses a strength testing device suitable for carbon fiber composite materials. The patent describes a device comprising: a base with a limiting groove; a bidirectional threaded rod within the limiting groove; a limiting slider fitted onto the bidirectional threaded rod; an annular track mounted on the limiting slider; an annular groove on the inner wall of the annular track; a limiting ring within the annular groove; a limiting post within the limiting ring; a clamping plate fitted onto the limiting post; and a connecting bracket mounted on one side of the limiting post. This invention utilizes… The design incorporates a bidirectional threaded rod that rotates to stretch carbon fiber material. During this stretching process, a second motor and connecting bracket drive a limiting ring to rotate, thus performing a torsion test on the carbon fiber material. This increases the testing difficulty of the carbon fiber material and allows for the acquisition of more carbon fiber strength indices. While the aforementioned device achieves its intended purpose through simple component assembly, the strength test involves a relatively large output force, and the device lacks protective devices, making it highly susceptible to injury to testing personnel. Furthermore, the use of a threaded rod's moving structure results in significant wear on the threaded rod, reducing the service life of critical components.

[0005] In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

The protective mechanism 2 is provided on one side of the surface of the workbench 1, and the combined mechanism 3 is provided at one end of the workbench 1.

[0029] The protective mechanism 2 includes a first slide groove 201, a limiting groove 202, a fitting block 203, a transparent protective cover 204, a second slide groove 205, a groove 206, a spring 207, and a limiting block 208. The first slide groove 201 is provided on one side of the surface of the workbench 1. The limiting groove 202 is provided on the side wall of the first slide groove 201. The fitting block 203 is fitted inside the first slide groove 201. The transparent protective cover 204 is fixedly connected to one end of the fitting block 203. The second slide groove 205 is provided on the side wall of the fitting block 203. The groove 206 is provided at one end of the second slide groove 205. The spring 207 is connected inside the groove 206. The limiting block 208 is connected to the other side of the spring 207.

[0030] In this embodiment, after the device is clamped, the transparent protective cover 204 can be installed on the workbench 1 via the remote control assembly mechanism 3. First, press the limiting block 208. The limiting block 208 will overcome the elasticity of the spring 207 and slide in the second slide groove 205. After the limiting block 208 is inserted into the second slide groove 205, the fitting block 203 can be inserted into the first slide groove 201. When the fitting block 203 is fully inserted into the first slide groove 201, that is, the limiting groove 202 and the second slide groove 205 are aligned, the spring 207 returns to its elasticity, so that the limiting block 208 is inserted into the limiting groove 202 again, thereby reliably fixing the transparent protective cover 204.

[0031] In a further preferred embodiment of the present invention, the positions of the limiting groove 202 and the second sliding groove 205 are aligned, and the dimensions of the second sliding groove 205 and the limiting block 208 are matched.

[0032] In this embodiment, the limiting groove 202 and the second sliding groove 205 are arranged opposite to each other. The limiting groove 202 is used to position and fix the limiting block 208 to prevent the interlocking block 203 and the transparent protective cover 204 from sliding accidentally. The second sliding groove 205 provides a sliding channel for the movement of the limiting block 208, so as to realize the controllable push-pull and position locking function of the transparent protective cover 204.

[0034] In this embodiment, the first slide groove 201 is used to guide the fitting block 203 to slide along the surface of the workbench 1 to achieve the locking and fixing of the transparent protective cover 204. The fitting block 203 is embedded in the first slide groove 201, which serves to connect the transparent protective cover 204 and the workbench 1. At the same time, in conjunction with the limiting structure, it ensures the stability and adjustability of the transparent protective cover 204 during use.

[0035] In a further preferred embodiment of the present invention, eight sets of grooves 206 and springs 207 are provided in the second slide groove 205, and the eight sets of grooves 206 and springs 207 are distributed at equal intervals in the second slide groove 205.

[0036] In this embodiment, the groove 206 provides installation space for the spring 207, so that the spring 207 can be stably positioned in the second slide groove 205. One end of the spring 207 is connected to the groove 206, and the other end is connected to the limiting block 208, providing elastic force to push the limiting block 208 to cooperate with the limiting groove 202, thereby realizing the automatic locking and reset function of the fitting block 203 and the transparent protective cover 204.

[0037] In a further preferred embodiment of the present invention, one side of the surface of the limiting block 208 is fitted into the interior of the limiting groove 202, and the limiting block 208 forms a mutual sliding structure with the limiting groove 202 and the second sliding groove 205 respectively through the spring 207.

[0038] In this embodiment, the limiting block 208 is embedded in the limiting groove 202 under the elastic force of the spring 207, which serves to fix the position of the fitting block 203 and restrict the transparent protective cover 204. When adjustment is required, the limiting block 208 can slide in the second sliding groove 205 and disengage from the limiting groove 202, thereby realizing the controllable movement and positioning of the transparent protective cover 204.

[0039] In a further preferred embodiment of this utility model, the combined mechanism 3 includes a cylinder 301, a positioning rail 302, a mounting plate 303, a rotating frame 304, a motor 305, a mounting groove 306, an electric push rod 307, and a clamping plate 308. The cylinder 301 is mounted on one side of the surface of the workbench 1, the positioning rail 302 is mounted on one side of the workbench 1, the output end of the cylinder 301 is connected to the mounting plate 303, the rotating frame 304 is fitted into one side of the mounting plate 303, one side of the rotating frame 304 is connected to the output end of the motor 305, the other end of the rotating frame 304 is provided with a mounting groove 306, the inner wall of the mounting groove 306 is mounted with an electric push rod 307, and the output end of the electric push rod 307 is connected to the clamping plate 308.

[0040] In this embodiment, the electric push rod 307 is first activated. The output end of the electric push rod 307 is connected to the clamping plate 308. The push rod action can drive the clamping plate 308 to clamp the workpiece. Then, the mounting plate 303 is moved smoothly in a straight line along the surface of the worktable 1 by the cylinder 301 and the positioning rail 302, thereby completing the tensile strength test. Finally, when the torque needs to be tested, the motor 305 is activated. The motor 305 drives the rotating frame 304 to rotate, thereby driving the clamped workpiece to rotate, completing the torque test.

[0041] In a further preferred embodiment of the present invention, positioning rails 302 are fitted on both sides of the mounting plate 303, and the positioning rails 302 are disposed on both sides of the cylinder 301. The mounting plate 303 and the positioning rails 302 form a sliding structure with each other through the cylinder 301.

[0042] In this embodiment, the positioning rails 302 are arranged on both sides of the cylinder 301 and fit into the mounting plate 303 to guide the mounting plate 303 to slide smoothly in a straight line along the surface of the worktable 1. At the same time, the rails restrict the movement direction of the mounting plate 303, ensuring that the combined mechanism 3 achieves accurate positioning and stable operation under the push of the cylinder 301.

[0043] In a further preferred embodiment of the present invention, the rotating frame 304 forms a mutually rotating structure with the motor 305 and the mounting plate 303, and the main body of the motor 305 is supported on the mounting plate 303.

[0044] In this embodiment, the motor 305 is mounted on the mounting plate 303, and its output end is connected to the rotating frame 304. The motor 305 drives the rotating frame 304 to rotate, thereby adjusting the angle of the mounting slot 306 and the electric push rod 307. The motor 305 controls the rotation direction and angle of the rotating frame 304 to assist the clamping plate 308 in completing the precise positioning and multi-angle operation functions when clamping items.

[0045] In a further preferred embodiment of this utility model, two sets of electric push rods 307 are provided in the mounting groove 306, and their positions are aligned with each other.

[0046] In this embodiment, the electric push rod 307 is installed in the mounting slot 306 of the rotating frame 304, and the output end is connected to the clamping plate 308. The clamping plate 308 is driven to open and close by the telescopic action to realize the clamping and release of the item. At the same time, the two sets of electric push rods 307 are arranged opposite to each other to ensure that the clamping force is uniform and stable.

[0047] In summary, firstly, the electric push rod 307 is activated. The output end of the electric push rod 307 is connected to the clamping plate 308. The push rod's movement can drive the clamping plate 308 to clamp the workpiece. After the device is clamped, the transparent protective cover 204 can be installed on the worktable 1 via the remote control assembly mechanism 3. First, the limit block 208 is pressed. The limit block 208 will overcome the elasticity of the spring 207 and slide in the second slide groove 205. After the limit block 208 is engaged in the second slide groove 205, the fitting block 203 can be embedded in the first slide groove 201. After block 203 is fully embedded in the first slide groove 201, that is, the positions of the limiting groove 202 and the second slide groove 205 are aligned, the spring 207 returns to its elasticity, causing the limiting block 208 to be embedded in the limiting groove 202 again, thereby reliably fixing the transparent protective cover 204. Then, the mounting plate 303 moves smoothly in a straight line along the surface of the worktable 1 through the cylinder 301 and the positioning rail 302, thereby completing the tensile strength operation. Finally, when the torque needs to be tested, the motor 305 is started, and the motor 305 drives the rotating frame 304 to rotate, thereby driving the clamped workpiece to rotate, completing the torque test.
