DETAILED DESCRIPTION

[0033] In order to make the technical means, creative features, purposes and effects of the present application easy to understand, the present application is further described below in combination with specific embodiments.

[0034] As Figures 1 to 6As shown, the multi-stage buffered oil cylinder strength detection device provided by the embodiment of the application comprises a workbench 1, a rotating seat 2 is fixedly installed on the top of the workbench 1, a rotating shaft 3 is rotatably installed on the inner wall of the rotating seat 2, rotating blocks 4 are symmetrically rotatably installed on the outer wall of the rotating shaft 3, support plates 5 are fixedly installed on the top of the rotating blocks 4, a fixing assembly is arranged on the top of the workbench 1, the fixing assembly comprises a hook plate 9, a driving assembly is arranged on the inner wall of the workbench 1, and the driving assembly comprises a hydraulic cylinder 10; before detection work is performed, the driving assembly pushes the support plates 5 to rotate around the rotating shaft 3, the support plates 5 are in an inclined state after being rotated, at this time, the side of the support plates 5 close to the fixing assembly is at a low position, the piston rod to be detected is moved above the support plates 5, the piston rod above the support plates 5 slides towards the fixing assembly along the inclined surface of the support plates 5, and the sliding piston rod finally reaches below the hook plate 9, at this time, the hydraulic cylinder 10 drives the support plates 5 to reverse, the support plates 5 drive the piston rod to move upwards, and the piston rod moves upwards into the inside of the hook plate 9 and is fixed by the support plates 5. When the strength of the piston rod of a traditional oil cylinder is detected, the piston rod is manually fixed, and the operation of a clamp, the adjustment of a position and the like are required, which is complicated and time-consuming. The hydraulic cylinder 10 of the present application pushes the support plates 5 to rotate to an inclined state, so that the piston rod automatically slides along the inclined surface to the fixing assembly, and then the support plates 5 are reversed to drive the piston rod to move upwards to cooperate with the hook plate 9 to complete the fixing. The whole process does not require manual operation of the clamp one by one, greatly saves the time for fixing the piston rod, improves the efficiency of the preparation work before detection, manual fixing of the piston rod requires an operator to manually operate the clamp, the labor intensity is large, and long-time operation is prone to human errors due to fatigue. The device realizes automatic fixing, the operator only needs to convey the piston rod to the support plates 5, reduces the labor burden, avoids the problems of insecure fixing or position deviation caused by human factors, and improves the stability and reliability of detection.

[0035] As Figure 1 and Figure 5As shown, the fixing assembly further comprises a protrusion 6 fixedly installed on the top of the workbench 1, the top of the protrusion 6 is provided with a connecting block 7 fixedly connected with the protrusion 6 through a bolt A8, and a hook plate 9 is fixedly installed on the top of the connecting block 7 and located between the two supporting plates 5.The hook plate 9 is fixed between the two support plates 5 through the cooperation of the connecting block 7, the bolt A8 and the protrusion 6. The support plate 5 is driven to rotate by the driving assembly, so that the side of the support plate 5 close to the hook plate 9 moves downward. At this time, since the support plate 5 is in an inclined state, the piston rod moved above the support plate 5 will slide along the support plate 5 towards the hook plate 9. When the piston rod slides to the hook plate 9, it will be stopped below the arc surface of the hook plate 9 due to the restriction of the hook plate 9. At this time, the driving assembly reverses the support plate 5. When the support plate 5 reverses, it will push the piston rod to move towards the arc surface of the hook plate 9 until the piston rod contacts the arc surface of the hook plate 9. At this time, the piston rod is clamped between the hook plate 9 and the support plate 5, thereby realizing the automatic fixing of the piston rod. Since the hook plate 9 is located in the middle position of the two support plates 5, when the driving assembly continues to push the support plate 5 to reverse, the support plate 5 will cooperate with the hook plate 9 to press the piston rod. The hook plate 9 is installed with a laser displacement sensor, which is aligned with the surface of the piston rod. Through the action of the hydraulic cylinder 10, the piston rod is pressed, and the axial compression amount and the radial bending deformation amount of the piston rod under the pressure are monitored in real time, so as to determine whether the strength of the piston rod is qualified, thereby realizing the effect of automatic detection. In summary, when the piston rod slides to the hook plate 9, it is stopped below the arc surface of the hook plate 9 due to the restriction of the hook plate 9. Then, the support plate 5 reverses to push the piston rod to contact the arc surface of the hook plate 9, and the piston rod is clamped between the hook plate 9 and the support plate 5. This fixing method utilizes the rigidity characteristics of the mechanical structure, which can provide stable and reliable fixing force for the piston rod, prevent the piston rod from moving or shaking during the detection process, and ensure the accuracy and reliability of the detection result. The whole fixing process does not need manual intervention and is completely completed automatically by relying on the rotation of the support plate 5 driven by the driving assembly. From the piston rod being placed on the support plate 5 to being automatically slid to the hook plate 9 and then being automatically clamped and fixed, a series of actions are smooth and continuous, realizing the full automation of the piston rod fixing, greatly improving the detection efficiency and reducing the errors and uncertainties caused by manual operation. After the piston rod is automatically fixed, the driving assembly continues to push the support plate 5 to reverse, and the support plate 5 cooperates with the hook plate 9 to directly press and detect the piston rod. The two links of automatic fixing and automatic detection are closely connected, without the need for additional operation and adjustment, so that the whole detection process is more efficient and smooth, the detection period is shortened, and the production efficiency is improved. The support plate 5 cooperates with the hook plate 9 to press the piston rod, which can simulate the pressure and stress conditions of the piston rod in the actual use process, more truly reflect the strength performance of the piston rod. Compared with some simple local detection methods, this detection method can more comprehensively and accurately evaluate the quality of the piston rod, and provide a stronger basis for the quality control of the product. The hook plate 9 cooperates with the support plate 5 to apply shear force to the piston rod. By replacing the hook plate 9 with different end shapes and adjusting the number of hook plates 9, various possible stress scenarios of the piston rod can be simulated, thereby improving the detection comprehensiveness and accuracy.

Figures 1 to 4As shown, the taking-out assembly includes two taking-out plates 19, which are fixedly installed at one end of the support plate 5 respectively, the taking-out plates 19 are located below the discharging frame 16, the top of the workbench 1 is symmetrically provided with accommodating grooves 20, and the two taking-out plates 19 are located at the inner sides of the two accommodating grooves 20 respectively; when the driving assembly drives the support plate 5 to rotate, the support plate 5 drives the taking-out plates 19 to rotate, the taking-out plates 19 pass through the inner side of the discharging frame 16 when rotating, so that a piston rod body 18 at the lowest position in the discharging frame 16 is hooked out, the hooked-out piston rod body 18 falls to the upper side of the support plate 5, so that the effect of automatic feeding is realized; since the taking-out plates 19 have a certain length, when the support plate 5 continues to rotate, the taking-out plates 19 can limit the rear piston rod body 18 from falling, so that the subsequent piston rod body 18 is prevented from falling to affect the reset of the support plate 5; since the taking-out assembly can efficiently and stably complete the automatic feeding task, the time and labor cost required by manual feeding are reduced, meanwhile, errors and uncertainties possibly caused by manual operation are avoided, so that the detection equipment can perform the piston rod strength detection at a higher speed and precision, the overall detection efficiency is greatly improved, and the demand of large-scale production is met.

[0039] As Figure 1 and Figures 8 to 11As shown, the inner wall of one end of the supporting plate 5 away from the hook plate 9 is rotatably provided with two driving shafts 21, and the outer wall of the driving shaft 21 is fixedly provided with a driving roller 22. Every two driving rollers 22 form a group, and a rotating belt 23 is drivingly installed between every group of driving rollers 22. One side of the rotating belt 23 is provided with a running assembly, and one side of the supporting plate 5 is provided with a limiting assembly. The cooperation of the driving shaft 21 and the driving roller 22 enables the rotating belt 23 to rotate. When the detection work is carried out, the piston rod body 18 will move above the rotating belt 23. After the device completes a detection work, the driving assembly drives the supporting plate 5 to rotate downward first and then reset. In this process, the rotating belt 23 will interact with the running assembly, and at the same time, it is affected by the limiting assembly. The rotating belt 23 can only rotate in a single direction. Because there is enough friction between the surface of the rotating belt 23 and the piston rod body 18, the piston rod body 18 will rotate when the rotating belt 23 rotates. As the core transmission component of the hydraulic system, the shear strength detection of the piston rod needs to cover multiple angle conditions. When the piston rod moves in the oil cylinder, it may change the direction of shear frequently due to mechanical vibration, hydraulic impact or external load deviation. If only a single direction is detected, the key failure mode may be missed. The rotation of the piston rod body 18 enables the detection equipment to detect the strength of the piston rod body 18 from different directions, breaking the limitation of traditional single direction detection. The multi-angle detection realized by the rotation of the piston rod body 18 can more comprehensively understand the performance of the piston rod in all directions, so as to more accurately evaluate its overall strength, greatly improve the reliability and accuracy of the detection result, help to find potential problems of the piston rod in actual use, and provide more valuable basis for product quality improvement and optimization. The driving assembly drives the supporting plate 5 to rotate, and then triggers the interaction between the rotating belt 23 and the running assembly, realizing the automatic rotation of the rotating belt 23. There is no need for manual intervention in the rotation operation of the piston rod. The whole process is closely matched with the automatic feeding, fixing and other links, forming a complete automatic detection process. This not only improves the detection efficiency, but also reduces the influence of human factors on the detection result, ensuring the stability and consistency of the detection process.

[0040] As Figure 1 and Figure 11As shown, the operating assembly includes a connecting plate 24 located on the top of the workbench 1, which is fixedly connected with the workbench 1 through the arranged bolts B25, and the top of the connecting plate 24 is fixedly installed with a driving plate 26 located on one side of the rotating belt 23; the driving plate 26 is fixed on one side of the rotating belt 23 through the cooperation of the connecting plate 24 and the bolt B25, and when the device completes a detection work, the driving assembly will drive the supporting plate 5 to rotate downward first and then reset near one side of the hook plate 9, and the rotating belt 23 will move with the supporting plate 5 when rotating, and the rotating belt 23 will pass through the surface of the driving plate 26 when moving, and the rotating belt 23 will rotate under the action of the surface friction of the driving plate 26, and because of the action of the limiting assembly, the rotating belt 23 can only rotate in one direction, which can prevent the rotating belt 23 from rotating back with the piston rod, so as to adjust the angle of the piston rod body 18 by the rotating belt 23, and the driving plate 26 is fixed on the top of the workbench 1, and when the supporting plate 5 drives the rotating belt 23 to pass through the driving plate 26, the surface friction thereof drives the rotating belt 23 to rotate stably, which provides a clear power source for the system, and the rotating belt 23 operates in a preset mode, which lays a foundation for the rotation angle control of the piston rod, and the limiting assembly can prevent the rotating belt 23 from rotating back with the piston rod, which ensures one-way rotation and provides a key guarantee for angle control, and the friction between the rotating belt 23 and the piston rod body 18 ensures reliable transmission, so that the rotating belt 23 can stably drive the piston rod to rotate, and the hydraulic cylinder 10 can accurately control the moving distance of the rotating belt 23 on the surface of the driving plate 26, thereby realizing accurate control of the rotation of the rotating belt 23, and because the rotation of the rotating belt 23 is controllable, the rotary motion transmitted by the friction can also be accurately controlled, and finally the rotation angle of the piston rod body 18 is accurately regulated and controlled.

[0041] As shown in Figures 8 to 10 The limiting assembly includes a ratchet wheel 27 fixedly installed on the outer wall of each of the two driving shafts 21, a torsion spring shaft 28 fixedly installed on the inner wall of the supporting plate 5, a pawl 29 installed on the outer wall of the torsion spring shaft 28, and the pawl 29 is in clamped connection with the ratchet wheel 27; the pawl 29 limits the ratchet wheel 27 under the action of the torsion spring shaft 28, so that the ratchet wheel 27 can only rotate in one direction, and because the ratchet wheel 27 is connected with the driving shaft 21, the rotating belt 23 can also only rotate in one direction, which avoids detection failure caused by chaotic rotation direction.
