Description
Technical Field
[0001] The utility model relates to the technical field of hydraulic test benches, and more specifically, to a frame-type hydraulic test bench structure. Background Art
[0002] A hydraulic test bench is a precision device designed specifically for the tensile performance evaluation of materials and structures. It utilizes hydraulic technology to generate a powerful traction force and scientifically measures the mechanical behavior of materials or components under tensile conditions. The core of such a test bench lies in its efficient hydraulic system, which can precisely control and gradually increase the tensile force applied to the sample until the sample reaches the breaking point or a predetermined test standard. During the entire test process, the hydraulic oil is pressurized by a pump, and the energy is transmitted through a hydraulic cylinder and ultimately converted into a tensile force on the sample. Hydraulic test benches are usually equipped with highly sensitive sensors and advanced data acquisition systems. These devices can real-time monitor and record key parameters during the test, including but not limited to load force values, displacement changes, breaking point data, etc.
[0003] Although traditional hydraulic test benches perform excellently in terms of accuracy and force control, especially when conducting in-depth mechanical property analysis on a single workpiece, their designs often focus on providing detailed and accurate test results. However, the design of single-workpiece testing reveals limitations in efficiency when faced with batch testing requirements. Each test requires adjusting the fixture and reloading, which undoubtedly takes a large amount of time in a batch testing scenario and affects the overall test efficiency. Especially when facing rapid quality control on the production line or large-scale material certification requirements, how to invent a frame-type hydraulic test bench structure to improve these problems has become an urgent problem for those skilled in the art.

[0023] Referring to Figures 3-5, the blanking mechanism includes a plurality of shaft brackets 15 fixedly connected to the side wall of the material baffle 9. A rotating shaft 16 is rotatably connected inside the shaft bracket 15. A baffle 17 is arranged inside the material baffle 9. A dial rod 18 is fixedly connected to the side wall of the rotating shaft 16, and the dial rod 18 is in contact with the baffle 17; a tension spring 19 is fixedly connected to the outer side wall of the material baffle 9, and the end of the tension spring 19 is fixedly connected to the baffle 17. The baffle 17 is elastically connected to the material baffle 9 through the tension spring 19; a rack 20 is fixedly connected to the side wall of the clamping seat 10. The end of the rotating shaft 16 is rotatably connected to a gear 21. The gear 21 is meshed with the rack 20. A pawl shaft 23 is fixedly connected to the side wall of the gear 21. A pawl 22 is rotatably connected to the outer side wall of the pawl shaft 23. A torsion spring 24 is sleeved on the side wall of the pawl shaft 23. One end of the torsion spring 24 is fixedly connected to the pawl shaft 23, and the other end is fixedly connected to the pawl 22. A ratchet 25 is fixedly connected to the outer side wall of the rotating shaft 16. The ratchet 25 is meshed with the pawl 22. During the reset process of the clamping wall 3, the clamping seat 10 is pushed by the clamping wall 3, so that the rack 20 drives the gear 21 to rotate. The gear 21 drives the rotating shaft 16 to rotate through the meshed pawl 22 and ratchet 25. The rotating shaft 16 drives the dial rod 18 to rotate. The dial rod 18 rotates to push the baffle 17 to lift upward. After the cylindrical workpiece 8 is unobstructed, it rolls between the jigs 11 due to gravity, completing the filling of the cylindrical workpiece 8. By cyclic filling, the problem of the limited efficiency exposed by the single-workpiece test design in the face of batch test requirements is solved, and the overall test efficiency is improved.
[0024] The working principle of the structure of this frame-type hydraulic test bench: Place the cylindrical workpiece 8 in the fixture 11, provide hydraulic power for the hydraulic cylinder 12, and cause the hydraulic rod 13 to push out of the hydraulic cylinder 12. When the hydraulic rod 13 extends, it drives the push rod 14 to rotate with the clamping wall 3 as the fulcrum. Through the first connecting rod, the fixture 11 is pushed to clamp both ends of the workpiece, and the same-direction torque is provided for multiple threaded shafts 5. Since the threads at both ends of the threaded shaft 5 are arranged in the opposite direction, the rotation of the threaded shaft 5 drives the threaded bracket 4 thereon to move in the opposite direction, and through the clamping wall 3, the clamping seat 10 and the fixture 11 are driven to move in the opposite direction, thereby providing a tensile force for the cylindrical workpiece 8 to test the maximum tensile force that the cylindrical workpiece 8 can withstand. When the applied tensile force exceeds the range that the cylindrical workpiece 8 can withstand, the cylindrical workpiece 8 is broken. After recording the data, by contracting the hydraulic cylinder 12 and the hydraulic rod 13, the fixture 11 releases the clamped cylindrical workpiece 8, and the broken cylindrical workpiece 8 falls off for recovery. By rotating multiple threaded shafts 5 in the reverse direction, the clamping wall 3 is reset. During the reset process, the clamping wall 3 pushes the clamping seat 10, and the rack 20 on the side wall of the clamping seat 10 drives the gear 21 to rotate. The gear 21 drives the rotating shaft 16 to rotate through the meshed ratchet pawl 22 and the ratchet wheel 25. The rotating shaft 16 drives the lever 18 to rotate. The rotation of the lever 18 pushes the baffle 17 to lift upward. After there is no obstruction for the cylindrical workpiece 8, it rolls between the fixtures 11 due to gravity, completing the loading of the cylindrical workpiece 8. When the cylindrical workpiece 8 starts to fall, the lever 18 rotates to a position separated from the baffle 17. The baffle 17 loses the upward thrust of the lever 18 and quickly falls back under the pulling force of the tension spring 19 to block the rolling of other cylindrical workpieces 8.
[0025] It should be noted that the specific model and specifications of the motor need to be selected according to the actual specifications of the device, etc. The specific selection calculation method adopts the existing technology in this field, so it will not be elaborated in detail.

For those skilled in the art, various changes and modifications can be made to the present invention. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
