Description

Technical Field

[0001] The present invention relates to the technical field of strength detection, and in particular to an adjustable strength detector and a use method thereof. Background Art

[0002] The connector strength tensile tester is a precision instrument designed for evaluating the strength of structural connections and has a wide range of applications. The tester uses an advanced tension application mechanism to accurately perform mechanical tests on the connection parts, deeply analyze their performance under stress, and thus verify whether the connector meets the established strength standards.

[0003] The actual operation and testing process of the detector is more suitable to be carried out in a laboratory or indoor environment. This is because the laboratory or indoor environment can provide a stable and controllable testing space, effectively shielding the interference of external factors such as weather changes, ensuring the accuracy and reliability of the test results, and greatly facilitating the regular maintenance and calibration of the detector, helping to extend its service life and maintain the continuous stability of the test performance.

[0004] In the actual operation of the strength tester, a significant defect of the current tester is the lack of flexible adjustment of the clamping lateral spacing and the function of changing the tensile torque. This limitation makes it impossible to quickly and effectively adjust the clamping space of the tester during the tensile test to adapt to the test objects of different sizes and shapes, thus limiting the scope of application of the tester. At the same time, due to the lack of the ability to dynamically adjust the tensile torque, it is difficult for the tester to accurately simulate the changes in the tensile force on the connector, which affects the accuracy and practicality of the test.

[0005] Thus, the existing detector is not convenient enough to use and cannot meet the diverse testing requirements. Therefore, it is necessary to design and modify the strength detector and its use method to effectively prevent the phenomenon that its testing process does not meet the actual requirements. Summary of the invention

[0006] In order to solve the problems raised in the above background technology, the present invention provides an adjustable strength tester and a method of use, which has the advantage of quickly adjusting the clamping space and driving torque of the tester, and solves the problem that the existing testers cannot flexibly adjust the clamping space and test torque.

[0007] The present invention provides the following technical solution: an adjustable strength detector and a method of using the same, the strength detector comprising a carrying box, a stretching mechanism, a supporting mechanism, an adjusting mechanism and a driving mechanism, The stretching mechanism comprises a lower clamping body, an upper clamping body, a movable frame, a supporting frame, a sliding block, a screw rod, a limit frame and a limit rod, so that the upper clamping body and the lower clamping body can stretch the connecting piece for strength testing.

[0008] The lower clamp is located on the top of the carrying box. The upper clamp body is arranged above the lower clamp body and is used to fix the other end of the connection piece to be detected, so that during the detection process, the upper clamp body and the lower clamp body jointly clamp the connection piece.

[0009] The movable frame is fixedly connected to the surface of the upper clamping body, and support frames are arranged on the left and right sides thereof. The support frames serve as a carrier of a moving part and are used to support and guide the movement of the sliding block and the upper clamping body.

[0010] The bottom of the support frame is slidably connected to the top of the carrying box, and the inner wall thereof is slidably connected to the front and back sides of the movable frame, so that the movable frame can slide up and down in the support frame, which allows the support frame to move horizontally relative to the carrying box. At the same time, the movable frame can slide up and down under the constraint of the support frame.

[0011] The sliding block is placed inside the movable frame and is slidably connected to the inner wall of the movable frame, so that the sliding block can move inside the movable frame.

[0012] The inner wall of the hole of the sliding block is movably connected with a screw rod 1, the top of the screw rod 1 is movably connected to the top of the inner wall of the support frame through a bearing, and the bottom passes through the interior of the carrying box and is connected to the driving mechanism, so that the screw rod 1 can rotate inside the sliding block, thereby driving the sliding block and the movable frame to move up and down.

[0013] The limit frame is fixedly connected to the top of the carrying box, and a limit rod is arranged between the front and rear sides of the inner wall thereof. The limit rod passes through the support frame to limit the left and right movement of the support frame. The limit frame serves as a frame for supporting and guiding the left and right movement of the support frame, and the limit rod limits the left and right movement of the support frame to prevent it from exceeding a predetermined range during movement.

[0014] The supporting mechanism comprises a supporting frame and a supporting plate, which are used to provide stable support for the supporting frame.

[0015] The support frame is fixedly connected to the back of the carrying box to provide stable support. A support plate is fixedly connected to the top of the front side. The surface of the support plate is slidably connected to the perforated inner wall of the support frame to support the support frame without affecting the left and right sliding of the support frame.

[0016] The adjusting mechanism comprises a connecting block, a second screw rod, a rotating wheel and a limiting plate, and is used to achieve precise adjustment of the position of the supporting frame.

[0017] The connecting block is fixedly connected to the back of the supporting frame, and the bottom of the connecting block is slidably connected to the top of the limiting frame, so that the supporting frame can slide on the top of the limiting frame through the connecting block.

[0018] The second screw is threadedly connected in the threaded hole of the connecting block, and both left and right ends thereof are fixedly connected to rotating wheels. By rotating the rotating wheel, the second screw can be driven to rotate in the connecting block, thereby adjusting the position of the support frame.

[0019] The limit plate is fixedly connected to the outer side of the back of the limit frame. The middle hole of the limit plate is used to place screw rod 2 to limit the rotation of screw rod 2. By limiting the rotation range of screw rod 2, it can be ensured that the support frame will not exceed the predetermined position range during the adjustment process.

[0020] The driving mechanism comprises a double-axis motor, a connecting rod, a bevel gear 1, a bevel gear 2, a large gear, a small gear, a fixed rod and a spur gear, which are used to drive the overall mechanism to operate smoothly.

[0021] The dual-axis motor is fixedly connected to the bottom of the inner wall of the carrying box, and connecting rods are fixedly connected to both left and right ends of the dual-axis motor, so that the dual-axis motor is used as a power source and the power is transmitted to the connecting rods.

[0022] The outer side of the connecting rod passes through the inner wall of the carrying box and is movably connected to the inner wall of the carrying box through a bearing, which allows the connecting rod to rotate freely in the carrying box without being hindered by the carrying box, thereby ensuring smooth transmission of power.

[0023] Bevel gear one is fixedly connected to the left and right sides of the connecting rod, and bevel gear two is meshed at the bottom of bevel gear one, so as to transmit the rotational power of the connecting rod to bevel gear two and change the rotation direction.

[0024] The bottom of the bevel gear 2 close to the dual-axis motor and the bottom of the bevel gear 2 far from the dual-axis motor are respectively connected with a large gear and a small gear, so that the large gear and the small gear can rotate synchronously with the two bevel gears 2 in the bearing box.

[0025] The inner walls of the large gear and the small gear are fixedly connected with a fixing rod, and the bottom of the fixing rod is movably connected to the inner wall of the bearing box through a bearing, so that the large gear and the small gear are stably operated in a predetermined position.

[0026] The spur gear is fixedly connected to the bottom of the screw rod 1 and can mesh with one of the large gear and the small gear separately to drive the screw rod 1 to rotate. By changing the meshing state of the spur gear and the large gear or the small gear, the rotation speed and torque of the screw rod 1 can be adjusted.

[0027] The reinforcement block is fixedly connected between the bottom of the front side of the support frame and the top of the carrying box, so as to enhance the connection strength between the support frame and the carrying box.

[0028] The handle is fixedly connected to the top of the outer side of the rotating wheel, so that the rotating wheel can be driven to rotate by turning the handle, and the surface of the handle has elasticity and anti-slip ability.

[0029] The spacer is fixedly connected to the bottom of the left and right sides of the support frame, the inner wall of the sliding hole of the spacer is slidably connected to the surface of the limit rod, and the spacer has elasticity and vibration reduction capabilities to prevent direct collision between the support frame and the limit frame.

[0030] A method for using an adjustable strength detector comprises the following steps: S1: When the equipment is in a static state, the carrying box remains stable and motionless, the lower clamp is connected to the top of the carrying box, and the upper clamp is suspended directly above the lower clamp. The movable frame is connected to the support frame so that the movable frame can slide smoothly under the guidance of the support frame. At the same time, the sliding block is driven by screw 1 to prepare for the subsequent stretching operation.

[0031] S2: When the tensile test is required, the dual-axis motor starts immediately, and its power is transmitted to bevel gear 1 through the connecting rod to drive it to rotate. The clever meshing of bevel gear 1 and bevel gear 2 converts the vertical rotation of the motor into lateral rotation, thereby driving the large gear and the small gear to rotate synchronously. At this time, the spur gear at the bottom of screw 1 is tightly meshed with the large gear, and the rotation force of the large gear drives screw 1 to rotate. The rotation of screw 1 further pushes the sliding block to move along its axis, squeezing the movable frame to slide upward, and the movable frame drives the upper clamp to rise together, so as to test the tear strength of the structural connector.

[0032] S3: During the stretching process, if the position of the support frame needs to be adjusted to expand the clamping space or increase the torque, the rotating wheel in the adjustment mechanism can be rotated to drive the second screw to rotate. The rotation of the second screw is transmitted to the support frame through the connecting block, driving it to slide smoothly left and right in the limit frame. At the same time, as the support frame slides, the first screw and the spur gear also move outward until the spur gear and the pinion gear re-engage, so as to achieve the expansion of the support frame outward, which not only increases the test width of the connector, but also enhances the tensile strength of the upper clamp due to the change in torque, thereby simulating the change in the tensile strength of the structural connector. In this process, the support frame and the support plate in the support mechanism provide solid support for the support frame to ensure its stability during the sliding process. The addition of the reinforcement block further enhances the bearing capacity of the support frame. The limiting mechanism composed of the limit frame and the limit rod effectively prevents the support frame from exceeding the preset range during the sliding process, and at the same time plays a good guiding role. Through this series of optimized designs, the equipment not only has the ability to quickly adjust the clamping space, but also significantly improves the adaptability of the torque, solving the limitations of traditional detectors in clamping space and torque adjustment.

[0033] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention can flexibly adjust the clamping space and driving torque of the detector through the synergistic effect of the overall mechanism, effectively solving the problem of limited clamping space caused by the non-adjustable support frame of the existing detector, and realizing the rapid adjustment of the clamping space and torque. In addition, by changing the torque, the present invention can also simulate the changes of different pulling forces on the structural connector, providing strong support for the accurate evaluation of the connection strength.

[0034] 2. The present invention enhances the stability and load-bearing capacity of the equipment by providing a support mechanism. The support frame and the support plate provide support for the support frame to ensure that it will not be deformed or damaged when sliding left and right. BRIEF DESCRIPTION OF THE DRAWINGS

At the same time, the movable frame 4 can slide up and down under the constraint of the support frame 5.

[0041] The sliding block 6 is placed inside the movable frame 4 and is slidably connected to the inner wall of the movable frame 4 , so that the sliding block 6 can move inside the movable frame 4 .

[0042] The sliding block 6 has a pair of screws 7 movably connected to the inner wall of the hole of the sliding block 6. The top of the screw 7 is movably connected to the top of the inner wall of the support frame 5 through a bearing, and the bottom passes through the interior of the carrying box 1 and is connected to the driving mechanism, so that the screw 7 can rotate inside the sliding block 6, thereby driving the sliding block 6 and the movable frame 4 to move up and down.

[0043] The limit frame 8 has a pair, and the limit frame 8 is fixedly connected to the top of the carrying box 1. A limit rod 9 is set between the front and rear sides of the inner wall. The limit rod 9 passes through the support frame 5 to limit the left and right movement of the support frame 5. The limit frame 8 serves as a frame to support and guide the left and right movement of the support frame 5. The limit rod 9 limits the left and right movement of the support frame 5 to prevent it from exceeding a predetermined range during movement.

[0044] refer to Figure 4 The supporting mechanism includes a supporting frame 10 and a supporting plate 11, which are used to provide stable support for the supporting frame 5.

[0045] The support frame 10 is fixedly connected to the back of the carrying box 1 to play a role of stable support. The top of the front side is fixedly connected to a support plate 11. The surface of the support plate 11 is slidably connected to the perforated inner wall of the support frame 5, thereby supporting the support frame 5 without affecting the left and right sliding of the support frame 5.

[0046] As a technical optimization solution of the present invention, by setting a support mechanism, the stability and load-bearing capacity of the device are enhanced.

[0048] The connecting block 12 is fixedly connected to the back of the supporting frame 5 , and its bottom is slidably connected to the top of the limiting frame 8 , so that the supporting frame 5 can slide on the top of the limiting frame 8 through the connecting block 12 .

[0049] The second screw rod 13 is threadedly connected in the threaded hole of the connecting block 12, and its left and right ends are fixedly connected to the rotating wheel 14. By rotating the rotating wheel 14, the second screw rod 13 can be driven to rotate in the connecting block 12, thereby adjusting the position of the support frame 5, and the two support frames can be moved from the inside to the outside.

[0050] The limit plate 15 is fixedly connected to the outer side of the back side of the limit frame 8. The middle hole of the limit plate 15 is used to place the screw 2 13 to limit the rotation of the screw 2 13. By limiting the rotation range of the screw 2 13, it can be ensured that the support frame 5 will not exceed the predetermined position range during the adjustment process.

[0051] As a technical optimization solution of the present invention, by setting an adjustment mechanism, the device can be easily adjusted left and right to adapt to different working requirements. The cooperation between the rotating wheel 14 and the screw rod 13 makes the adjustment process simpler and faster.

[0052] refer to Figure 6 The driving mechanism includes a dual-axis motor 16, a connecting rod 17, a bevel gear 18, a bevel gear 2 19, a large gear 20, a small gear 21, a fixed rod 22 and a spur gear 23, which are used to drive the entire mechanism to operate smoothly.

[0053] The dual-axis motor 16 is fixedly connected to the bottom of the inner wall of the carrying box 1 , and the left and right ends thereof are fixedly connected to connecting rods 17 , so that the dual-axis motor 16 is used as a power source and the power is transmitted to the connecting rods 17 .

[0054] The outer side of the connecting rod 17 passes through the inner wall of the carrying box 1 and is movably connected to the inner wall of the carrying box 1 through a bearing, which allows the connecting rod 17 to rotate freely in the carrying box 1 without being hindered by the carrying box 1, ensuring smooth transmission of power.

[0055] Bevel gear 1 18 is fixedly connected to both the left and right sides of the connecting rod 17 , and bevel gear 2 19 is meshed with the bottom of bevel gear 18 , so as to transmit the rotational power of the connecting rod 17 to bevel gear 2 19 and change the rotation direction.

[0056] The bottom of the bevel gear 19 close to the dual-axis motor 16 and the bottom of the bevel gear 19 far from the dual-axis motor 16 are respectively connected with a large gear 20 and a small gear 21, so that the large gear 20 and the small gear 21 can rotate synchronously with the two bevel gears 19 in the carrying box 1.

[0057] The inner walls of the large gear 20 and the small gear 21 are fixedly connected with a fixing rod 22, and the bottom of the fixing rod 22 is movably connected to the inner wall of the carrying box 1 through a bearing, so that the large gear 20 and the small gear 21 are stably operated at a predetermined position.

[0058] The spur gear 23 is fixedly connected to the bottom of the screw 7 and can be engaged with one of the large gear 20 and the small gear 21 separately to drive the screw 7 to rotate. By changing the meshing state of the spur gear 23 with the large gear 20 or the small gear 21, the rotation speed and torque of the screw 7 can be adjusted.

[0059] As a technical optimization solution of the present invention, the automatic control of the equipment is realized by setting a driving mechanism. The cooperation of the double-axis motor 16, bevel gear 1 18, bevel gear 2 19, large gear 20 and small gear 21 enables the screw 1 7 to rotate as required, thereby realizing the stretching operation. At the same time, this design also improves the reliability and durability of the equipment.

[0060] refer to Figure 4 The reinforcement block 24 is fixedly connected between the bottom of the front side of the support frame 10 and the top of the carrying box 1 , so as to enhance the connection strength between the support frame 10 and the carrying box 1 .

[0061] As a technical optimization solution of the present invention, by providing the reinforcement block 24, the stability of the support frame 10 is further enhanced, so that the equipment can remain stable even when subjected to a large load.

The inner wall of the sliding hole of the spacer 26 is slidably connected to the surface of the limit rod 9. The spacer 26 has elasticity and vibration reduction capabilities to prevent direct collision between the support frame 5 and the limit frame 8.

[0065] As a technical optimization solution of the present invention, by providing the spacer 26, the friction and collision between the support frame 5 and the limit frame 8 are reduced, thereby extending the service life of the equipment.

[0066] A method for using an adjustable strength detector comprises the following steps: S1: The connector strength tensile tester is a testing instrument designed for structural connection strength assessment. It verifies whether the connector meets the established strength standard through precise mechanical testing. When the equipment is in a static state, the carrier box 1 remains stable and motionless, the lower clamp body 2 is connected to the top of the carrier box 1, and the upper clamp body 3 is suspended directly above the lower clamp body 2. The movable frame 4 is connected to the support frame 5, so that the movable frame 4 can slide smoothly under the guidance of the support frame 5. At the same time, the sliding block 6 drives the movable frame 4 to move under the drive of the screw 7 to prepare for the subsequent stretching operation.

[0067] S2: When the demand for stretching test arises, the dual-axis motor 16 is immediately started, and its power is transmitted to the bevel gear 18 through the connecting rod 17, driving it to rotate. The clever meshing of bevel gear 18 and bevel gear 2 19 converts the vertical rotation of the motor into lateral rotation, thereby driving the large gear 20 and the small gear 21 to rotate synchronously. At this time, the spur gear 23 at the bottom of the screw 17 is tightly meshed with the large gear 20, and with the help of the rotational force of the large gear 20, the screw 17 is driven to rotate. The rotation of the screw 17 further pushes the sliding block 6 to move along its axial direction, squeezing the movable frame 4 to slide upward, and the movable frame 4 drives the upper clamp 3 to rise together, so as to test the tear strength of the structural connector.

[0068] S3: During the stretching process, if the position of the support frame 5 needs to be adjusted to expand the clamping space or increase the torque, the rotating wheel 14 in the rotating adjustment mechanism can be used to drive the screw rod 13 to rotate. The rotation of the screw rod 13 is transmitted to the support frame 5 through the connecting block 12, driving it to slide smoothly left and right in the limit frame 8. At the same time, as the support frame 5 slides, the screw rod 17 and the spur gear 23 also move outward until the spur gear 23 re-engages with the pinion 21, so as to achieve the expansion of the support frame 5 outward, which not only increases the test width of the connector, but also enhances the tensile strength of the upper clamp 3 due to the change in torque, thereby simulating the change in the pulling force of the structural connector. In this process, the support frame 10 and the support plate 11 in the support mechanism provide solid support for the support frame 5 to ensure its stability during the sliding process. The addition of the reinforcement block 24 further enhances the bearing capacity of the support frame 10. The limiting mechanism composed of the limit frame 8 and the limit rod 9 effectively prevents the support frame 5 from exceeding the preset range during the sliding process, and at the same time plays a good guiding role. Through this series of optimized designs, the equipment not only has the ability to quickly adjust the clamping space, but also significantly improves the adaptability of the torque, solving the limitations of traditional detectors in clamping space and torque adjustment.

[0069] Working principle and use process of the present invention: The connector strength tensile tester is a testing instrument designed for structural connection strength assessment. It verifies whether the connector meets the established strength standard through precise mechanical testing. When the equipment is in a static state, the carrying box 1 remains stable and motionless, the lower clamp body 2 is connected to the top of the carrying box 1, and the upper clamp body 3 is suspended directly above the lower clamp body 2. The movable frame 4 is connected to the support frame 5, so that the movable frame 4 can slide smoothly under the guidance of the support frame 5. At the same time, the sliding block 6 drives the movable frame 4 to move under the drive of the screw rod 7 to prepare for the subsequent stretching operation. When the stretching test demand occurs, the double-axis motor 16 is immediately started, and its power is transmitted to the bevel gear 1 18 through the connecting rod 17 to drive it to rotate. The clever meshing of the bevel gear 1 18 and the bevel gear 2 19 converts the vertical rotation of the motor into lateral rotation, thereby driving the large gear 20 and the small gear 21 to rotate synchronously. At this time, the spur gear 23 at the bottom of the screw rod 7 is tightly meshed with the large gear 20, and the screw rod 7 is driven to rotate with the help of the rotation force of the large gear 20. The rotation of the screw rod 1 7 further pushes the sliding block 6 to move along its axis direction, squeezing the movable frame 4 to slide upward, and the movable frame 4 drives the upper clamp 3 to rise together, so as to simulate the strength of the structural connector being stretched or torn for testing. During the stretching process, if the position of the support frame 5 needs to be adjusted to expand the clamping space or increase the torque, the rotating wheel 14 in the rotating adjustment mechanism can be used to drive the screw rod 2 13 to rotate. The rotation of the screw rod 2 13 is transmitted to the support frame 5 through the connecting block 12, driving it to slide smoothly left and right in the limit frame 8. At the same time, as the support frame 5 slides, the screw rod 1 7 and the spur gear 23 also move outward until the spur gear 23 re-engages with the pinion 21, realizing the expansion of the support frame 5 outward, which not only increases the test width of the connector, but also enhances the tensile strength of the upper clamp 3 due to the change in torque. In this process, the support frame 10 and the support plate 11 in the support mechanism provide solid support for the support frame 5 to ensure its stability during the sliding process. The addition of the reinforcement block 24 further enhances the bearing capacity of the support frame 10. The limiting mechanism composed of the limiting frame 8 and the limiting rod 9 effectively prevents the support frame 5 from exceeding the preset range during the sliding process, and at the same time plays a good guiding role. Through this series of optimized designs, the equipment not only has the ability to quickly adjust the clamping space, but also significantly improves the adaptability of the torque, solving the limitations of traditional detectors in clamping space and torque adjustment.

[0070] In summary: the present invention can flexibly adjust the clamping space and driving torque of the detector through the synergistic effect of the overall mechanism, effectively solving the problem of limited clamping space caused by the non-adjustable support frame of the existing detector, and realizing the rapid adjustment of the clamping space and torque. In addition, by changing the torque, the present invention can also simulate the changes of different pulling forces on the structural connector, providing strong support for the accurate evaluation of the strength of the structural connection, thereby solving the problem that the existing detector cannot flexibly adjust the clamping space and change the test torque.
