Description

Technical Field

[0001] This utility model relates to the field of tensile testing technology, specifically to a straddle-type horizontal online tensile testing machine. Background Technology

[0002] Existing horizontal tensile testing machines use two clamping parts spaced a certain distance apart to perform 180-degree horizontal tensile tests on simple products such as wire ropes and chains. In contrast, the straddle-type horizontal online tensile testing machine allows operators to step into the testing area, facilitating the adjustment of various parameters and tensile testing.

[0003] The prior art, disclosed in CN219455683U, provides a hull-shaped horizontal tensile testing device, including a worktable. A working groove is provided on the top of the worktable. A stepper motor is embedded in the inner wall of the right side of the working groove. Two sets of stepper motors are arranged in a front-to-back configuration. Multiple screws are rotatably mounted on the inner wall of the left side of the working groove. One end of each screw is connected to the output end of the stepper motor. A slider is slidably mounted in the working groove. The clamping structure allows for quick fixation and testing of the test specimen by rotating the connecting seat without changing the clamping mold. The locking mechanism facilitates locking the clamping structure.

[0004] In the aforementioned patent, when testing plate or column test specimens, the clamping block is fixed by only pushing the clamping block with an electric actuator. Since plate or column test specimens require a large tensile force during tensile testing, it is difficult to adapt to such a large tensile force by simply pushing with an electric actuator. This will directly cause the plate or column test specimen to be pulled out of the clamping block during testing, making it impossible to conduct the corresponding test, which greatly reduces the practicality of the tensile testing equipment. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings of the prior art and provide a horizontal online tensile testing machine for straddle-type applications, thus solving the aforementioned technical problems.

[0006] To achieve the above objectives, this utility model employs the following technical solution: a straddle-type horizontal online tensile testing machine, comprising a machine body. A first clamping assembly for fixing the test specimen is fixedly installed on one side of the machine body. A push-pull assembly for fixing and pulling the test specimen is movably installed on the machine body. A controller is fixedly installed on one side of the machine body. The push-pull assembly includes a movable block and a second clamping assembly that move within the machine body. The second clamping assembly includes a column with a rectangular groove for placing a plate-shaped test specimen. A second fixing member and a third fixing member for fastening the test specimen are threadedly installed on both sides of the rectangular groove on the column. The second and third fixing members are shaped like cylinders made of nylon material fixed to both ends of a central threaded rod. The shape of the second and third fixing members, with cylinders made of nylon material fixed to both ends of the central threaded rod, allows the entire second fixing member to move directly within the column when the outer cylinder of the second fixing member rotates, greatly improving the integrated movement of the internal structure of the straddle-type horizontal online tensile testing machine.

[0007] Furthermore, a display for showing tensile force values ​​is fixedly installed on the side of the machine body near the first clamping assembly. The column also has a cylindrical hole within a rectangular groove for placing a cylindrical test specimen, and a straight slot for placing a rope is formed on one side of the column. A first fixing member for securing the rope is movably installed within the straight slot on the column. This movable installation of the first fixing member within the straight slot enhances the versatility of the horizontal online tensile testing machine for securing test specimens.

[0008] Furthermore, the column has a retaining groove on the side away from the first fixing member, and the column has several threaded holes of different sizes in the retaining groove. The threaded holes are used to detect the tensile force of a plate-shaped test specimen with bolts. The use of threaded holes to detect the tensile force of a plate-shaped test specimen with bolts improves the versatility of the straddle-type horizontal online tensile testing machine for fixing test specimens.

[0009] Furthermore, a rectangular slot is provided on one side of the movable block, and a second motor is fixedly installed within this slot. The output end of the second motor is connected to a shaft, which is fixedly installed with the second clamping assembly. This allows the second motor to directly rotate the second clamping assembly during operation, improving the overall integrity of the internal structure of the straddle-type horizontal online tensile testing machine.

[0010] Furthermore, the main body includes a support frame, and a mounting groove is provided on the side of the support frame near the controller. A drive component for driving the push-pull assembly is fixedly installed in the mounting groove of the support frame.

[0011] Furthermore, the drive assembly includes a first motor and a drive shaft fixed within the support frame. The first motor is electrically connected to the controller, and a lead screw is fixedly connected to the output end of the first motor. The movable block is movably mounted on the lead screw and drive shaft through threaded holes and cylindrical holes on both sides. This movable mounting of the movable block on the lead screw and drive shaft allows the first motor to directly move the movable block to its limit position during rotation, improving the practicality of the straddle-type horizontal online tensile testing machine.

[0012] Furthermore, the support frame has a test component for detecting the tensile force of the test specimen fixedly installed in the mounting slot. A first connecting line is fixedly connected to the side of the test component near the push-pull component, and a second connecting line is fixedly connected to the top of the test component. The first connecting line is fixedly connected to the first clamping component, and the second connecting line is fixedly connected to the display. The fixed connection of the second connecting line to the display allows the tensile force value detected by the test component to be directly displayed on the display, improving the intelligence of the straddle-type horizontal online tensile testing machine. Beneficial effects

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention places different test specimens into corresponding rectangular slots, cylindrical holes, embedding slots, or straight slot holes. After the test specimens are placed, the user only needs to rotate the cylinder on the outside of the corresponding fixing screw to make the corresponding fixing component move closer to the cylinder through the screw, thereby firmly fixing test specimens of different shapes, which greatly improves the firmness of fixing test specimens in the straddle-type horizontal online tensile testing machine.

Detailed Implementation

[0022] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0023] Example

[0024] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6This application will be further described in detail below. A horizontal in-line tensile testing machine includes a machine body 1. A first clamping assembly 3 for fixing a test specimen is fixedly installed on one side of the machine body 1. A push-pull assembly 5 for fixing and pulling the test specimen is movably installed on the machine body 1. A controller 4 is fixedly installed on one side of the machine body 1. The push-pull assembly 5 includes a movable block 51 and a second clamping assembly 53 that move within the machine body 1. The second clamping assembly 53 includes a column 532. A rectangular groove 535 for placing a plate-shaped test specimen is formed within the column 532. A second fixing member 534 and a third fixing member for fastening the test specimen are threadedly installed on both sides of the rectangular groove 535 on the column 532. 536, the second fixing member 534 and the third fixing member 536 are shaped as cylindrical bodies made of nylon fixed at both ends of the middle lead screw. A display 2 for displaying tensile force values ​​is fixedly installed on the side of the machine body 1 near the first clamping assembly 3. The column 532 also has a cylindrical hole 533 for placing a columnar test specimen within a rectangular groove 535. A straight groove 537 for placing a rope is opened on one side of the column 532. A first fixing member 531 for fixing the rope is movably installed in the straight groove 537 of the column 532. A retaining groove 538 is opened on the side of the column 532 away from the first fixing member 531. The 538 has several threaded holes 539 of different sizes. The threaded holes 539 are used to detect the tensile force of a plate-shaped test specimen with bolts. A rectangular groove is provided on one side of the movable block 51. A second motor 52 is fixedly installed in the rectangular groove of the movable block 51. The output end of the second motor 52 is connected to a shaft, which is fixedly installed with the second clamping assembly 53. The machine body 1 includes a support frame 11. A mounting groove 13 is provided on the side of the support frame 11 near the controller 4. A drive assembly 14 for driving the push-pull assembly 5 is fixedly installed in the mounting groove 13 of the support frame 11. The drive assembly 14 includes a first motor 14 fixed in the support frame 11. 1 and drive shaft 143, first motor 141 is electrically connected to controller 4, output end of first motor 141 is fixedly connected to lead screw 142, movable block 51 is movably mounted on lead screw 142 and drive shaft 143 through threaded holes and cylindrical holes on both sides, support frame 11 is fixedly installed in mounting groove 13 with test assembly 12 for detecting the tensile force of test sample, test assembly 12 is fixedly connected to the side of push-pull assembly 5 with first connecting line 121, test assembly 12 is fixedly connected to the top of test assembly 12 with second connecting line 122, first connecting line 121 is fixedly connected to first clamping assembly 3, and second connecting line 122 is fixedly connected to display 2.

[0025] Because the machine body 1 has a large operating space inside and the support frame 11 is not high, the user can step into the machine body 1 to fix the test specimen to be tested in the first clamping component 3 and the second clamping component 53, which greatly improves the convenience of using the step-in horizontal online tensile testing machine.

[0026] Since the first connecting line 121 of the tension sensor 123 is fixedly connected to the first clamping assembly 3, when the push-pull assembly 5 moves, the tension sensor 123 can detect the value of the tension and display the value on the display 2 through the second connecting line 122, so that the user can observe the value of the tension more intuitively, which greatly improves the convenience of using the straddle-type horizontal online tensile testing machine.

[0027] Since the cylinders on both sides of the second fixing member 534 are made of nylon, when the cylinders on both sides of the second fixing member 534 come into contact with the test specimen and are squeezed and contracted, the large friction force generated by the nylon material will firmly fix the test specimen between the second fixing member 534 and the third fixing member 536, greatly reducing the probability that the test specimen will be pulled out directly.

[0028] Since the bolts on the plate-shaped test specimens are of different sizes, the multiple threaded holes 539 of different sizes opened in the column 532 can fit together perfectly, so that the straddle-type horizontal online tensile testing machine can perform corresponding tensile tests on the plate-shaped test specimens with bolts, greatly improving the diversity of test specimen selection for the straddle-type horizontal online tensile testing machine.

[0029] The first clamping component 3 can be manually rotated around the cylinder fixed inside the machine body 1, and since the first connecting line 121 is fixed in the cylinder inside the machine body 1, the rotation of the first clamping component 3 will not affect the first connecting line 121.

[0030] The working principle of this utility model is explained below: Unless otherwise specified, all internal mechanical structures of the straddle-type horizontal online tensile testing machine are fixed by threads. To allow for a more intuitive observation of the technical features, the bolt connections are appropriately concealed in the diagram. When using the straddle-type horizontal online tensile testing machine, the user can place cylindrical test specimens into the cylindrical holes 533 of the column 532, plate-shaped test specimens into the rectangular slots 535, rope-shaped test specimens into the straight slot holes 537, and test specimens with bolts into the embedding slots 538. When the cylindrical, plate-shaped, and rope-shaped test specimens are placed in their corresponding positions, the user directly rotates the corresponding first fixing member 531, second fixing member 534, or third fixing member 536, causing them to move closer together within the column 532, thereby firmly fixing the test specimens in the corresponding slots. Alternatively, the test specimen can be inserted into a hole. For specimens with bolts, the bolts can be screwed directly into the corresponding threaded hole 539. Users can also rotate the second clamping component 53 via the second motor 52 according to specific needs, while the first clamping component 3 is rotated manually. After the test specimen is clamped, the user only needs to start the first motor 141 via the controller 4. The started first motor 141 will rotate the lead screw 142, thereby moving the push-pull component 5 away from the first clamping component 3. The resulting tensile force value will be detected by the tensile sensor 123, which will display the value on the display 2 for the user to view. This allows the straddle-type horizontal online tensile testing machine to be used for test specimens of various shapes, while also providing a more secure fixation for the test specimens, greatly improving the practicality of the straddle-type horizontal online tensile testing machine and reducing the probability of the test specimens being pulled out.

[0031] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
