Description

Technical Field

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

[0002] A steel strength testing device is a precision instrument specifically designed to measure and evaluate the strength of steel materials. It tests the tensile strength, compressive strength, and other performance indicators of steel by applying a certain amount of tension or pressure to ensure that the material meets specific engineering and safety standards.

[0003] Some existing technologies use gears and shafts to drive a pressure column to test steel during testing. However, in actual use, the meshing design causes significant wear on the gear teeth under prolonged pressure, increasing equipment maintenance costs.

[0004] Therefore, this utility model provides a steel strength testing device. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a steel strength testing device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel strength testing device, comprising;

[0007] The mounting frame has limit components fixedly connected to both sides of its interior.

[0008] Pressure assembly; the pressure assembly includes a bidirectional motor mounted on a mounting frame, a rotating shaft seat 1 fixedly connected to the drive end of the bidirectional motor, a transmission rod 1 rotatably connected inside the rotating shaft seat 1, a transmission rod 2 rotatably connected to the end of the transmission rod 1 away from the rotating shaft seat 1, a rotating column rotatably connected to the end of the transmission rod 2 away from the transmission rod 1, a rotating shaft seat 2 fixedly connected to the outside of the rotating column, a base plate fixedly connected to the bottom end of the rotating shaft seat 2, and a pressure block fixedly connected to the bottom end of the base plate;

[0009] A moving component; a positioning component is fixedly connected to the top of the moving component, the moving component includes an effort arm, and sliding grooves are provided on both sides of the top of the mounting frame. A fulcrum seat is slidably connected to the sliding groove, and a resistance arm is rotatably connected to the outer side of the fulcrum seat. A rotating seat is rotatably connected to the end of the resistance arm away from the fulcrum seat.

[0010] In a preferred embodiment, the limiting component includes a first column fixedly connected to both sides of the mounting frame, a movable sleeve slidably connected to the outer side of the first column, and a second column fixedly connected to the middle of both sides of the mounting frame.

[0011] In a preferred embodiment, the positioning component includes a clamping plate fixedly connected to the rotating base, and a positioning bolt is internally threaded to the top of the clamping plate.

[0012] In a preferred embodiment, one end of the effort arm is fixedly connected to the movable sleeve, and the end of the effort arm away from the movable sleeve is fixedly connected to the rotating base.

[0013] In a preferred embodiment, the card plate is internally slidably connected to the second column.

[0014] In a preferred embodiment, the top end of the first rotating shaft seat is fixedly connected to the mounting frame.

[0015] In a preferred embodiment, the outer side of the movable sleeve is fixedly connected to the inside of the base plate.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0017] This invention utilizes a bidirectional motor to rotate a rotating shaft seat, which in turn rotates transmission rods one and two, pushing the rotating column to rotate. This ultimately causes the base plate to move up and down. The downward movement of the base plate causes the sliding sleeve to slide on the first column, thus pushing the effort arm to generate pressure. This pressure causes the fulcrum seat to slide on the groove, which in turn pushes the clamping plate upward through the lever principle, ensuring the clamping plate slides stably on the second column. Finally, the pressure block contacts the steel to be tested for pressure testing. This design, through motor drive and the lever principle, makes the entire operation process more flexible and controllable, allowing for precise pressure application and avoiding wear on the gear profile, thereby reducing equipment maintenance costs. Furthermore, by providing pressure in reverse, the force applied during the test can be controlled more precisely. This effectively avoids equipment damage or testing errors caused by excessive pressure, improving the accuracy of test results. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] like Figure 1 - Figure 3 As shown, this embodiment provides a technical solution: a steel strength testing device, comprising;

[0030] Mounting frame 1, with limit components 3 fixedly connected to both sides of the interior of mounting frame 1;

[0031] Pressure assembly 2; Pressure assembly 2 includes a bidirectional motor 21 mounted on the mounting frame 1. The drive end of the bidirectional motor 21 is fixedly connected to a rotating shaft seat 22. The top end of the rotating shaft seat 22 is fixedly connected to the mounting frame 1. A transmission rod 23 is rotatably connected inside the rotating shaft seat 22. A transmission rod 24 is rotatably connected to the end of the transmission rod 23 away from the rotating shaft seat 22. A rotating column 25 is rotatably connected to the end of the transmission rod 24 away from the transmission rod 23. A rotating shaft seat 26 is fixedly connected to the outside of the rotating column 25. A base plate 27 is fixedly connected to the bottom end of the rotating shaft seat 26. A pressure block 28 is fixedly connected to the bottom end of the base plate 27.

[0032] The mounting frame 1 serves as the basic structure of the entire device, used to fix and support all other components. The bidirectional motor 21 provides a power source to the entire system, capable of driving various transmission components connected subsequently. The bidirectional motor 21 allows the device to adjust the direction of applied force as needed. The two components, shaft seat 22 and transmission rod 23, together constitute a primary transmission chain from the motor to the final execution end. The shaft seat is responsible for supporting and positioning the rotation axis, while the transmission rod transmits the force from the motor to the next link. The transmission rod 24 and the rotating column 25 continue to extend the above transmission path, further transmitting the torque from the primary transmission system to a position closer to the object being acted upon. The design of the rotating column 25 allows the transmission rod 24 to adjust the angle or direction of applied force within a certain range, avoiding jamming. The design of the three structures, shaft seat 26, base plate 27, and pressure block 28, forms the end-effector structure that directly acts on the object under test. The base plate 27 provides a stable base on which the movable pressure block 28 is mounted. When subjected to force from above, it will press down on the fixed sample, thereby completing the actual mechanical performance test.

[0033] The limiting component 3 includes a first column 31 fixedly connected to both sides of the mounting frame 1, a movable sleeve 32 slidably connected to the outer side of the first column 31, and the outer side of the movable sleeve 32 fixedly connected to the inside of the base plate 27. A second column 33 is fixedly connected to the middle of both sides inside the mounting frame 1.

[0034] The first column 31 serves as the basic support structure for the limiting component 3, providing stable support and positioning reference. The movable sleeve 32 is slidably connected to the outside of the first column 31, allowing the base plate 27 to move up and down within a certain range. This design enables the equipment to adapt to samples of different heights, increasing the flexibility and applicability of the equipment. The base plate 27 is fixedly connected to the movable sleeve 32, providing a stable base for the pressure block 28. The design of the base plate 27 allows the pressure block 28 to evenly transmit force to the sample, ensuring uniform force distribution during the test. The second column 33 is located in the middle of both sides inside the mounting frame 1, used for further support or positioning of other components.

[0035] like Figure 1 , Figure 2 and Figure 4 As shown, the moving component 4 is fixedly connected to the top of the moving component 4. The moving component 4 includes an effort arm 41, one end of which is fixedly connected to the moving sleeve 32. The top of the mounting frame 1 has sliding grooves 42 on both sides. A fulcrum seat 43 is slidably connected to the sliding groove 42. A resistance arm 44 is rotatably connected to the outside of the fulcrum seat 43. A rotating seat 45 is rotatably connected to the end of the resistance arm 44 away from the fulcrum seat 43. The end of the effort arm 41 away from the moving sleeve 32 is fixedly connected to the rotating seat 45.

[0036] The design of the effort arm 41 enables the moving component 4 to effectively transmit power, thereby achieving the positioning and fixation of the steel sample. The slide groove 42 is slidably connected to the fulcrum seat 43. The design of the slide groove 42 allows the fulcrum seat 43 to move freely within a certain range. The fulcrum seat 43 is connected to the mounting frame 1 through the slide groove 42, allowing the fulcrum seat 43 to slide on the slide groove 42, thereby adjusting its position to adapt to steel samples of different sizes. The design of the resistance arm 44 helps to provide stable resistance during the test. The length of the resistance arm 44 is shorter than that of the effort arm 41, which allows the effort arm 41 to adapt to smaller pressures and obtain greater support force. The rotating seat 45 serves as the connection point between the effort arm 41 and the resistance arm 44. Its design helps to realize the conversion and transmission of force, thereby supporting the position of the clamping plate 51.

[0037] like Figure 1 and Figure 4 As shown, the positioning component 5 includes a clamping plate 51 fixedly connected to the rotating base 45, a positioning bolt 52 threadedly connected to the top of the clamping plate 51, and the interior of the clamping plate 51 is slidably connected to the column 33.

[0038] The clamping plate 51, as the basic component of the positioning assembly 5, provides a stable platform for further positioning operations. The positioning bolt 52 allows the user to adjust its position as needed to accommodate steel samples of different sizes or shapes. The upright column 33 provides vertical support and restraint for the clamping plate 51. This design helps maintain the stability of the clamping plate 51 during testing and prevents displacement or tilting caused by external forces.

[0039] Working principle:

[0040] like Figure 1 - Figure 4 As shown:

[0041] In use: First, place the steel to be tested on the clamping plate 51, and then fix the steel to be tested on the clamping plate 51 by rotating the positioning bolt 52. Next, start the bidirectional motor 21. The bidirectional motor 21 drives the rotating shaft seat 22 to rotate, which in turn drives the transmission rod 23 and the transmission rod 24 to rotate. At this time, when the transmission rod 24 is rotated by the transmission rod 23, the other end of the transmission rod 24 will drive the rotating column 25 to rotate on the rotating shaft seat 26, which in turn drives the base plate 27 to move up and down. As the base plate 27 moves downward, it causes the moving sleeve 32 to slide on the first column 31. At this time, the effort arm 41 is under pressure, causing the fulcrum seat 43 to slide on the groove 42. Then, the resistance arm 44 rotates on the rotating seat 45 under the push of the effort arm 41. At the same time, the lever principle pushes the clamping plate 51 upward, and the clamping plate 51 will slide back and forth on the second column 33 to ensure the stability of the movement of the clamping plate 51. Then, the pressure block 28 contacts the steel to be tested to perform the pressure test.

[0042] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
