Description

Technical Field

[0001] This utility model relates to the technical field of leather bag strap testing equipment, specifically to a hydraulically buffered leather bag strap vibration testing machine. Background Technology

[0002] In the leather products industry, the quality of leather straps directly affects the user experience and market competitiveness of products. Vibration testing, as a crucial method for evaluating the durability and reliability of leather straps, makes the performance of the testing equipment paramount. Currently, patent application number 202410048405.6 discloses a plastic strapping tensile strength testing device. This device focuses on the field of strapping strength testing. Through the coordinated operation of the testing mechanism and control mechanism within the testing components, it achieves a function that stops immediately upon breakage of the plastic strapping, effectively avoiding the problem of the testing device jamming and burning out due to failure to stop in time.

[0003] However, this technical solution has significant limitations. Firstly, its design is specifically for tensile strength testing of plastic strapping, and its testing principle differs significantly from the vibration testing of leather strapping, making it unsuitable for direct application to the vibration performance testing of leather strapping. Secondly, in the vibration testing scenario for leather strapping, existing technologies generally suffer from unstable fixation, lack of guiding and limiting mechanisms, and insufficient cushioning mechanisms. Ordinary clamping and fixing methods struggle to ensure the stability of leather strapping during prolonged vibration, easily leading to distorted test data; the lack of precise guiding and limiting causes the strapping's vibration trajectory to deviate, affecting test accuracy; and the absence of a cushioning mechanism subjectes the strapping to unnecessary impacts, failing to realistically simulate actual usage conditions. Utility Model Content

[0004] The purpose of this invention is to provide a hydraulically buffered leather strap vibration testing machine to solve the problems mentioned in the background art, such as unstable fixation, lack of guide limit and insufficient buffering mechanism in the existing technology under the leather strap vibration testing scenario.

[0005] To achieve the above objectives, this utility model provides a hydraulic buffer type leather bag strap vibration testing machine, including a pulling assembly. The pulling assembly fixes both ends of the strap to be tested, and the middle part of the strap is driven by a driving component on the driving platform to perform reciprocating vibration motion to realize the vibration test of the strap. The vibration motion of the strap is guided and limited by the track groove on the testing platform.

[0006] This setup uses a specific structure to securely fix both ends of the belt under test, providing a stable foundation for subsequent testing. The drive unit on the drive platform acts on the middle of the belt, causing it to reciprocate in an oscillating motion, thus achieving the oscillation test of the belt. The track groove on the test platform guides and limits the oscillation motion of the belt, ensuring that the belt oscillates along a predetermined path, guaranteeing a stable and controllable testing process.

[0007] Preferably, the driving component on the driving platform includes a turntable, on which an eccentric rod is mounted away from the center. One end of the eccentric rod is rotatably connected to the turntable via a bearing, and the other end of the eccentric rod is vertically mounted with an oscillating rod. One end of the oscillating rod is rotatably connected to the end of the eccentric rod via a bearing, and the other end of the oscillating rod is slidably engaged with the track groove.

[0008] In this setup, the turntable on the drive platform serves as a key component for power transmission. An eccentric rod is installed on the turntable away from its center, with one end rotatably connected to the turntable via a bearing, forming a movable connection structure. A vibrating rod is vertically mounted at the other end of the eccentric rod. Both ends of the vibrating rod are connected to the eccentric rod and the track groove via bearings, respectively. This connection method allows the eccentric rod to drive the vibrating rod to slide within the track groove as the turntable rotates, converting the turntable's circular motion into the reciprocating oscillating motion of the belt.

[0009] Preferably, the turntable is driven by a motor to rotate, which in turn drives the eccentric rod to move.

[0010] In this configuration, the turntable is driven by a motor to rotate, with the motor acting as the power source to provide stable rotational power. As the turntable rotates, it drives the eccentric rod to move, which in turn causes the oscillating rod to slide within the track groove, driving the belt to oscillate.

[0011] Preferably, the traction assembly includes a fixed platform, on which a hydraulic buffer is mounted. The base of the hydraulic buffer is fixed to the fixed platform, and a clamping member is mounted at one end to clamp and fix the end of the belt.

[0012] This setup uses a fixed platform in the tension assembly to provide a supporting foundation for the overall structure. The hydraulic damper base is fixed to the fixed platform, with one end connected to a clamping component. The hydraulic damper utilizes hydraulic principles to absorb and buffer impact forces during belt oscillation. The clamping component is used to hold and fix the ends of the belt, ensuring its stability during testing.

[0013] Preferably, the clamping member has a clamping opening, the end of the belt is located inside the clamping opening, and is pressed and fixed by a clamping block.

[0014] The clamping opening on this setting provides a space for the end of the belt to be placed. The clamping block applies pressure to the end of the belt through a specific structure in the clamping opening, pressing and fixing the belt to prevent it from coming out of the clamping opening during the test.

[0015] Preferably, the upper part of the clamping port is provided with an inner cavity, and a wedge block is horizontally slidably arranged in the inner cavity. A pressing block is provided at one end of the inclined surface of the wedge block. The upper end of the pressing block is attached to the inclined surface of the wedge block through the inclined surface, and the lower end is attached to the end of the belt body.

[0016] The inner cavity at the upper part of the clamping opening provides sliding space for the wedge block, which slides horizontally within the cavity. One end of the wedge block's inclined surface fits against the abutment block. When the wedge block slides, the inclined surface principle pushes the abutment block downward, thereby pressing the end of the belt.

[0017] Preferably, the other end of the wedge block is pressed and fixed by a threaded rod, which is threadedly connected to the clamping member. By screwing the threaded rod, one side of the wedge block is pressed, thereby operating the clamping block and pressing the end of the belt.

[0018] The other end of the wedge block is connected to the clamping component via a threaded rod. By screwing the threaded rod, the threaded rod pushes the wedge block to slide horizontally within the inner cavity of the clamping component, thereby pressing the wedge block and pushing the clamping block to apply pressure to the end of the belt, thus achieving a firm fixation of the belt.

[0019] Preferably, the wedge-shaped block has anti-slip teeth on the side that contacts the end of the belt.

[0020] This feature includes anti-slip teeth on the side of the wedge block that contacts the end of the belt. When the clamping block presses the belt, the anti-slip teeth contact the surface of the belt, increasing friction through the toothed structure to prevent the belt from slipping during clamping.

[0021] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0022] In this hydraulic buffer type leather bag strap vibration testing machine, the clamping component in the tensioning assembly adopts a structure of wedge block and abutment block for strap fixation. By turning the threaded rod, the wedge block is moved, and the abutment block is pressed against the end of the strap using the principle of inclined plane. At the same time, the anti-slip teeth on the abutment block further enhance the fixing effect. Compared with ordinary clamping methods, it can ensure stable fixation of the leather bag strap during long-term vibration testing, effectively avoid test data distortion caused by loosening, and greatly improve the accuracy and reliability of test results.

[0023] Regarding oscillation guidance, the oscillation motion of the belt is guided and limited by the track groove of the test bench. The drive unit of the drive bench, through the cooperation of a turntable, eccentric rod, and oscillation rod, drives the belt to oscillate back and forth within the path defined by the track groove. This precise guidance and limiting design ensures the stability of the belt's oscillation trajectory, prevents deviation during oscillation, and enables the test to realistically simulate the actual use conditions of leather bag straps, thereby improving the accuracy and effectiveness of the test.

[0024] In terms of cushioning performance, the hydraulic damper in the tensioning assembly plays a key role. During the oscillation of the belt, it can effectively absorb and buffer the impact force generated by the oscillation, avoiding unnecessary impact damage to the belt. It not only protects the leather belt sample, but also more realistically simulates the stress situation of the belt in actual use, further enhancing the reference value of the test results for the actual quality of the product. It provides an efficient and reliable solution for the quality inspection of leather belts, and powerfully promotes the high-quality development of the leather products industry.

[0031] 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.

[0032] This utility model provides a hydraulically buffered leather strap vibration testing machine, such as... Figure 1 , Figure 2 As shown, it includes a tensioning assembly 3, which fixes both ends of the belt body 4 to be tested. The middle part of the belt body 4 is driven by the driving component on the driving platform 1 to perform reciprocating oscillation motion, thereby realizing the oscillation test of the belt body 4. The oscillation motion of the belt body 4 is guided and limited by the track groove 21 on the test platform 2.

[0033] The tensioning assembly 3 securely fixes both ends of the belt body 4 to be tested through a specific structure, providing a stable foundation for subsequent testing. The driving component on the drive platform 1 acts on the middle of the belt body 4, causing it to reciprocate oscillating motion, thus realizing the oscillation test of the belt body 4. The track groove 21 on the test platform 2 guides and limits the oscillation motion of the belt body 4, ensuring that the belt body 4 oscillates along a predetermined path, ensuring that the testing process is stable and controllable. The basic workflow and core functions of the equipment are clearly defined. By fixing the belt body, driving oscillation, and guiding and limiting, the oscillation test of the leather bag strap is realized, laying the foundation for subsequent detailed structural design and ensuring the basic feasibility and standardization of the test.

[0034] In this embodiment, as Figure 2 As shown, the driving components on the drive platform 1 include a turntable 11. An eccentric rod 12 is installed on the turntable 11 away from the center. One end of the eccentric rod 12 is rotatably connected to the turntable 11 through a bearing. An oscillating rod 121 is vertically installed on the other end of the eccentric rod 12. One end of the oscillating rod 121 is rotatably connected to the end of the eccentric rod 12 through a bearing. The other end of the oscillating rod 121 is slidably engaged with the track groove 21.

[0035] The turntable 11 on the drive platform 1 serves as a key component for power transmission. An eccentric rod 12 is installed on the turntable 11 away from its center, with one end rotatably connected to the turntable 11 via a bearing, forming a movable connection structure. An oscillating rod 121 is vertically mounted on the other end of the eccentric rod 12. Both ends of the oscillating rod 121 are connected to the eccentric rod 12 and the track groove 21 via bearings, respectively. This connection method allows the eccentric rod 12 to drive the oscillating rod 121 to slide within the track groove 21 when the turntable 11 rotates, converting the circular motion of the turntable 11 into the reciprocating oscillating motion of the belt 4. This provides a simple and effective driving method. Through the ingenious design of the mechanical structure, the oscillating motion of the belt 4 is stably achieved. Compared to complex drive structures, it has the advantages of simple structure, low cost, and stable operation, while ensuring the regularity and continuity of the oscillating motion, thus improving the reliability of the test.

[0036] Specifically, such as Figure 1 , Figure 2 As shown, the turntable 11 rotates by a motor, which in turn drives the eccentric rod 12 to move.

[0037] The turntable 11 is driven by a motor to rotate, providing stable rotational power. As the turntable 11 rotates, it drives the eccentric rod 12, which in turn causes the oscillating rod 121 to slide within the track groove 21, driving the belt 4 to oscillate. This motor-driven system provides a stable and controllable power supply, allowing the motor speed to be adjusted according to testing requirements. This controls the rotational speed of the turntable 11, thereby adjusting the frequency and amplitude of the belt 4's oscillation, meeting the requirements of different testing conditions, and improving the equipment's applicability and testing flexibility.

[0038] Furthermore, such as Figure 3 As shown, the tensioning assembly 3 includes a fixed platform 31, on which a hydraulic buffer 32 is installed. The base of the hydraulic buffer 32 is fixed on the fixed platform 31, and a clamping member 33 is installed at one end. The clamping member 33 clamps and fixes the end of the belt body 4.

[0039] The fixed platform 31 in the tension assembly 3 provides a supporting foundation for the overall structure. The base of the hydraulic buffer 32 is fixed on the fixed platform 31, and one end is connected to the clamping member 33. The hydraulic buffer 32 utilizes hydraulic principles to absorb and buffer the impact force during the oscillation of the belt 4. The clamping member 33 is used to clamp and fix the end of the belt 4, keeping the belt 4 stable during the test. The hydraulic buffer 32 effectively protects the belt 4 from excessive damage from the oscillation impact force, extends the service life of the belt 4, and improves the authenticity of the test results, making them more consistent with actual usage conditions. The cooperation between the clamping member 33 and the fixed platform 31 ensures that the belt 4 is stably fixed during the test, preventing inaccurate test data due to loosening, and improving the reliability and stability of the test.

[0040] Furthermore, such as Figure 4 As shown, the clamping member 33 has a clamping opening 331, and the end of the belt body 4 is located in the clamping opening 331 and is pressed and fixed by the abutment block 335.

[0041] The clamping opening 331 on the clamping member 33 provides a placement space for the end of the belt 4. The pressing block 335 applies pressure to the end of the belt 4 within the clamping opening 331 through a specific structure, pressing and fixing the belt 4 to prevent it from coming out of the clamping opening 331 during the test. This simple and practical fixing method can quickly and effectively fix the end of the belt 4 within the clamping opening 331. It is easy to operate, has a reliable fixing effect, ensures the stability of the belt 4 during the oscillation test, avoids affecting the test results due to loosening of the belt 4, and improves test efficiency and accuracy.

[0042] Furthermore, such as Figure 4 As shown, an inner cavity 332 is provided at the upper part of the clamping port 331. A wedge block 334 is horizontally slidably arranged in the inner cavity 332. A pressing block 335 is provided at the inclined surface of one end of the wedge block 334. The upper end of the pressing block 335 is in contact with the inclined surface of the wedge block 334 through the inclined surface, and the lower end is in contact with the end of the belt body 4.

[0043] The inner cavity 332 at the upper part of the clamping port 331 provides sliding space for the wedge block 334, which slides horizontally within the cavity. One end of the wedge block 334 has an inclined surface that engages with the clamping block 335. When the wedge block 334 slides, the inclined surface pushes the clamping block 335 downwards, thereby pressing the end of the belt 4. Compared to a single clamping block 335 fixing method, the inclined surface structure of the wedge block 334 generates greater clamping force, enhancing the fixing effect on the end of the belt 4. Even under long-term, high-intensity vibration testing, it ensures stable fixing of the belt 4, effectively preventing loosening and improving the reliability and stability of the test. Furthermore, the ingenious structural design makes operation convenient.

[0044] Furthermore, such as Figure 4 As shown, the other end of the wedge block 334 is pressed and fixed by the threaded rod 333. The threaded rod 333 is threadedly connected to the clamping member 33. By screwing the threaded rod 333, one side of the wedge block 334 is pressed, thereby working on the abutment block 335 to achieve pressing of the end of the belt body 4.

[0045] The other end of the wedge block 334 is threadedly connected to the clamping member 33 via a threaded rod 333. By screwing the threaded rod 333, the threaded rod 333 pushes the wedge block 334 to slide horizontally within the inner cavity 332 of the clamping member 33, thereby pressing the wedge block 334 and pushing the abutment block 335 to apply pressure to the end of the belt body 4, thus achieving a firm fixation of the belt body 4. The threaded rod 333 makes the pressing operation of the wedge block 334 more precise and controllable. Users can adjust the moving distance of the wedge block 334 by screwing the threaded rod 333 according to factors such as the material and thickness of the belt body 4, thereby adjusting the pressing force of the abutment block 335 on the belt body 4, meeting the fixing requirements of belt bodies 4 of different specifications, improving the versatility and practicality of the equipment, and ensuring the stability and reliability of the fixing effect.

[0046] Furthermore, such as Figure 4 As shown, the wedge block 334 has anti-slip teeth 3351 on the side that is in contact with the end of the belt body 4.

[0047] The wedge-shaped block 334 has anti-slip teeth 3351 on the side that contacts the end of the strap 4. When the clamping block 335 presses the strap 4, the anti-slip teeth 3351 contact the surface of the strap 4, increasing friction through their toothed structure to prevent the strap 4 from slipping during clamping. The design of the anti-slip teeth 3351 further enhances the fixing effect on the strap 4, effectively preventing it from slipping even when subjected to large vibration forces. This ensures that the strap 4 remains stable and fixed throughout the test, improving the accuracy and reliability of the test results and providing stronger assurance for the quality inspection of leather straps.

[0048] In use, the hydraulic buffer type leather strap vibration testing machine of this utility model first places both ends of the strap 4 to be tested into the clamping openings 331 of the clamping member 33 of the tension assembly 3. By turning the threaded rod 333, the threaded rod 333 pushes the wedge block 334 to slide horizontally within the inner cavity 332 of the clamping member 33. The wedge block 334 uses the inclined plane principle to push the pressing block 335 downward, while the anti-slip teeth 3351 make close contact with the surface of the strap 4, increasing the friction, thereby firmly pressing and fixing the ends of the strap 4 into the clamping openings 331. The fixed platform 31 provides stable support for the entire tension assembly 3. The base of the hydraulic buffer 32 is fixed on the fixed platform 31. After the strap 4 is fixed, the clamping member 33 connected to one end can absorb and buffer the impact force generated by the vibration of the strap 4 during the test using the hydraulic principle, protecting the strap 4 and ensuring the authenticity of the test data.

[0049] After the belt 4 is fixed, the motor is started, providing stable rotational power to the turntable 11, causing it to rotate. As the turntable 11 rotates, the eccentric rod 12, installed away from its center, moves accordingly. One end of the eccentric rod 12 is rotatably connected to the turntable 11 via a bearing, while the other end, a vertically mounted oscillating rod 121, also moves under the influence of the eccentric rod 12. One end of the oscillating rod 121 is rotatably connected to the end of the eccentric rod 12 via a bearing, while the other end slides within the track groove 21, thus converting the circular motion of the turntable 11 into the reciprocating oscillating motion of the belt 4. The track groove 21 on the test bench 2 guides and limits the oscillating rod 121, ensuring that the belt 4 performs stable and controllable oscillating motion along a predetermined path.

[0050] Throughout the testing process, the motor can adjust its speed according to different testing requirements, thereby controlling the rotation speed of the turntable 11 and precisely adjusting the frequency and amplitude of the belt 4's oscillation to meet diverse testing conditions. The hydraulic buffer 32 continuously functions to buffer the impact force on the belt 4 during oscillation, preventing damage to the belt 4 due to excessive force, while ensuring the stable conduct of the test process. This allows the test results to accurately reflect the performance of the leather strap in actual use, providing a reliable basis for the quality evaluation of the leather strap.

Their structure and principle can be known to those skilled in the art through technical manuals or conventional experimental methods. In the idle part of this device, all the above-mentioned electrical components are connected by wires.
