Description

Technical Field

[0001] This utility model belongs to the technical field of acid and alkali resistance tensile testing technology for glass fiber composite materials, and specifically relates to an acid and alkali resistance tensile testing device. Background Technology

[0002] In the field of materials performance testing, glass fiber composites are widely used in many important industries such as aerospace, automotive manufacturing, and construction engineering due to their excellent mechanical properties and chemical stability. Understanding the tensile properties of these materials under different environments, especially their tensile properties under acid and alkali conditions, is crucial to ensuring their reliability and safety in practical applications.

[0003] Currently, existing tensile testing equipment can only test a single specimen at a time. When researchers or manufacturers need to test multiple specimens simultaneously, they have to equip themselves with multiple devices. This not only significantly increases the cost of equipment purchase and the space occupied, but also affects the consistency and comparability of test results for multiple specimens due to certain systematic errors between devices, further reducing testing efficiency and the accuracy of results. Therefore, there is an urgent need for an acid and alkali resistance tensile testing device to solve the above problems. Utility Model Content

[0004] In view of the problems mentioned above in the background art, the purpose of this utility model is to provide an acid and alkali resistance tensile testing device.

[0005] To achieve the above-mentioned technical objectives, the technical solution adopted by this utility model is as follows:

[0006] An acid and alkali resistance tensile testing device includes a frame, a bracket mounted on one side of the top of the frame, an electrical control box mounted on the bracket, a touch screen connected to the electrical control box, a support frame connected to the touch screen, the support frame mounted on one side of the bracket, and a plurality of tensile mechanisms mounted on the top of the frame. The plurality of tensile mechanisms are evenly arranged on the frame, wherein the distance between two adjacent tensile mechanisms is equal, and the electrical control box is connected to the tensile mechanisms.

[0007] Further specifying, the stretching mechanism includes a column, a base plate mounted at the bottom of the column, the base plate being locked onto a frame, a top plate mounted at the top of the base plate, a servo motor mounted at the top of the top plate, a screw jack connected to the power output end of the servo motor, a force sensor connected to the power output end of the screw jack, an L-shaped movable seat connected to the bottom of the force sensor, a slider mounted on the inner side of the L-shaped movable seat, a linear guide rail slidably connected to the slider, the linear guide rail mounted on the column, an upper adapter mounted at the bottom of the L-shaped movable seat, an upper clamp movably mounted at the bottom of the upper adapter, a test tube holder mounted on the column below the upper clamp, a test tube holder installed inside the test tube holder, a lower adapter mounted on the bottom of the base plate corresponding to the upper clamp, a lower clamp movably mounted on the lower adapter, a displacement sensor mounted on one side of the top plate, a locking block connected to the power output end of the displacement sensor, the locking block being locked onto one side of the L-shaped movable seat. This structural design facilitates tensile testing.

[0008] Furthermore, the number of the aforementioned tensile mechanisms is four identical small-sized tensile mechanisms and one large-sized tensile mechanism, all of which have identical structures. This structural design allows for the simultaneous tensile testing of multiple specimens.

[0009] Furthermore, the power output end of the screw jack is connected to an upper movable seat, the bottom of which is hinged to the top of a force sensor. The bottom of the force sensor is hinged to a lower movable seat, which is fixedly mounted on an L-shaped movable seat. This structural design facilitates the installation and use of the force sensor.

[0010] Furthermore, the column has a tray frame installed on the underside of the test tube, and a protective plate is installed on the tray frame. The protective plate has a through hole that matches the test piece. This structural design allows the protective plate to intercept the leaked acid or alkali solution in the test tube, thus providing a protective effect.

[0011] The beneficial effects of this utility model are as follows: This utility model provides an acid-base environment through a test tube to achieve acid-base resistant tensile testing. It can test multiple specimens simultaneously, reducing the floor space required and improving testing efficiency. A servo motor is used to raise and lower the screw lift, and the tensile display value is observed on the touch screen. Timing begins after the tensile force reaches the test value. The force sensor value and the recorded time are read to determine whether the specimen has failed. The touch screen can be used to set test parameters and display the test process data records and results. By testing multiple specimens simultaneously, the consistency and comparability of the results are not significantly affected, further improving testing efficiency and the accuracy of the results.

[0018] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0019] Example 1, such as Figure 1 and Figure 2 As shown, an acid and alkali resistance tensile testing device has a frame 2 installed on one side of the top of the frame 1. An electrical control box 3 is installed on the frame 2. The electrical control box 3 is connected to a touch screen 4. The touch screen 4 is connected to a support frame 5. The support frame 5 is installed on one side of the frame 2. Several tensile mechanisms 6 are installed on the top of the frame 1. The tensile mechanisms 6 are evenly arranged on the frame 1, and the distance between two adjacent tensile mechanisms 6 is equal. The electrical control box 3 is connected to the tensile mechanisms 6.

[0020] In this embodiment, during use, the specimen to be tested for tensile strength is first installed into the tensile mechanism 6. Multiple specimens can be installed at the same time. After installation, the electric control box 3 can automatically control the tensile mechanism 6 to perform the test by operating the touch screen 4, thereby realizing the tensile test control of multiple specimens.

[0021] Example 2, as Figure 1 , Figure 2 and Figure 3As shown, this embodiment adds the following structure based on embodiment 1: the tensioning mechanism 6 includes a column 7, a base plate 8 installed at the bottom of the column 7, the base plate 8 being locked onto the frame 1, a top plate 9 installed at the top of the base plate 8, a servo motor 10 installed at the top of the top plate 9, a screw jack 11 connected to the power output end of the servo motor 10, a force sensor 12 connected to the power output end of the screw jack 11, an L-shaped movable seat 13 connected to the bottom of the force sensor 12, a slider 14 installed on the inner side of the L-shaped movable seat 13, and a linear guide rail 15 slidably connected to the slider 14. 15 is mounted on the column 7. An upper adapter 16 is mounted at the bottom of the L-shaped movable seat 13. An upper clamp 17 is movably mounted at the bottom of the upper adapter 16. A test tube holder 18 is mounted on the column 7 below the upper clamp 17. A test tube 19 is installed inside the test tube holder 18. A lower adapter 20 is mounted on the bottom of the base plate 8 at the corresponding position of the upper clamp 17. A lower clamp 21 is movably mounted on the lower adapter 20. A displacement sensor 22 is mounted on one side of the top plate 9. A locking block 23 is connected to the power output end of the displacement sensor 22. The locking block 23 is locked and installed on one side of the L-shaped movable seat 13. This structural design facilitates tensile testing.

[0022] In this embodiment, before conducting the tensile test, a hole is drilled at the bottom of the test tube 19 to allow the specimen to pass through it. The connection between the test tube 19 and the specimen is then sealed with acid- and alkali-resistant sealant. After curing, the specimen is installed and fixed onto the test tube mounting base 18. Then, the upper clamp 17 and lower clamp 21 clamp the upper and lower sides of the specimen. Next, the operator adds acid or alkali solutions to the test tube, placing the specimen in an acidic or alkali environment. Simultaneously, the testing equipment does not directly contact the acid or alkali solution to avoid corrosion. Finally, by operating the touch screen 4, the electrical control box 3 automatically controls the tensile mechanism 6 to perform the test, causing the servo motor 10 to drive the screw jack 11, which in turn drives... Force sensor 12 drives L-shaped movable seat 13, which in turn drives slider 14 to slide upward along linear guide rail 15, simultaneously driving upper adapter 16. Upper adapter 16 drives upper clamp 17, which in turn drives the clamped specimen to perform a tensile test. During the tensile test, the tensile display value on the touch screen can be observed simultaneously. Timing starts after the tensile force reaches the test value. The control box 3 can read the value of force sensor 12 and record the time to determine whether the specimen has failed. The touch screen 4 can be used to set test parameters, display test process data records and results, and, in conjunction with displacement sensor 22, can view the tensile movement distance.

[0023] Example 3, as Figure 1 As shown, this embodiment adds the following structure to the basis of embodiment 1: the number of stretching mechanisms 6 is four identical small-sized stretching mechanisms and one large-sized stretching mechanism, and the four small-sized stretching mechanisms and one large-sized stretching mechanism have the same structure.

[0024] In this embodiment, when in use, it is possible to test four identical specimens and one large specimen simultaneously, reducing the floor space required and improving testing efficiency.

[0025] Example 4, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure based on embodiment 1: the power output end of the screw jack 11 is connected to an upper movable seat 24, the bottom of the upper movable seat 24 is hinged to the top of the force sensor 12, the bottom of the force sensor 12 is hinged to a lower movable seat 25, and the lower movable seat 25 is fixedly installed on the L-shaped movable seat 13.

[0026] In this embodiment, during installation, the upper movable seat 24 and the lower movable seat 25 are hinged to the upper and lower sides of the force sensor 12 to facilitate the installation and use of the force sensor 12.

[0027] Example 5, as Figure 2 and Figure 3 As shown, this embodiment adds the following structure to the embodiment 1: a tray frame 26 is installed on the lower side of the test tube 19 on the column 7, a protective plate 27 is installed on the tray frame 26, and a through hole 28 matching the test piece is provided on the protective plate 27.

[0028] In this embodiment, to prevent the acid and alkali solutions in the test tube 19 from flowing out during use, a protective plate 27 is installed on the lower side of the test tube 19, and holes are drilled in the protective plate 27 so that the bottom of the test piece passes through the protective plate 27 and is installed on the lower clamp 21. Then, the holes in the protective plate 27 are sealed. In this way, when the acid and alkali solutions in the test tube 19 flow out during use, they will only drip onto the protective plate 27, which will collect the flowing acid and alkali solutions and prevent the acid and alkali solutions from splashing and corroding other components.

[0029] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of 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.
