Description

Technical Field

[0001] This utility model belongs to the field of testing equipment technology, specifically relating to a rapid testing platform for multi-dimensional engineering mechanical properties. Background Technology

[0002] Multidimensional rapid testing platforms for engineering mechanical properties serve as crucial tools for testing modern engineering materials and structures, playing a key role in fields such as aerospace, construction engineering, and civil defense engineering. With the rapid development of modern industrial technology, the requirements for testing the mechanical properties of materials and structural components are increasing. Traditional uniaxial or biaxial testing methods are no longer sufficient to meet the performance evaluation needs under complex working conditions. The emergence of multidimensional rapid testing platforms for engineering mechanical properties is precisely to solve the problem of performance characterization of materials under complex stress states and to provide more comprehensive and reliable data support for engineering design.

[0003] A search revealed a Chinese patent with publication number CN222926502U, which discloses a rapid testing platform for multi-dimensional engineering mechanical properties. While this patent allows for the removal of bolts by rotating them counterclockwise through a mechanism, enabling the bracket and plate to detach from the testing table, and allowing the plate to remove the support cylinder for replacement of different parts to test materials of different specifications, the replacement of parts relies on bolt fixation. This operation is cumbersome and inefficient. Each replacement requires tightening / loosening multiple bolts, and according to industry standards, each bolt takes an average of 30-60 seconds (including hole alignment time). The four-bolt structure means that each replacement takes at least 2-4 minutes. When continuously testing samples of different specifications, dedicated personnel are required, increasing labor costs. Utility Model Content

[0004] To effectively improve testing efficiency, shorten the time for changing parts and tools, and solve the above-mentioned technical problems, this utility model achieves the following technical solution: A rapid testing platform for multi-dimensional engineering mechanical properties includes: a testing table.

[0005] Support frames are provided on the left and right sides of the top of the testing platform. Cylinders are provided on the crossbeams of the support frames, and pressure plates are provided at the output ends of the cylinders. A cornering mechanism is provided inside the testing platform.

[0006] The cornering mechanism includes a rotating block and a motor. The output end of the motor is connected to one end of the rotating block, and the rotating block is equipped with a locking mechanism and a lifting mechanism.

[0007] The positioning mechanism is located on one side of the rotating block and includes an assembly frame and a positioning plate. The assembly frame is located on one side of the rotating block and has two sets of guide rods inside. Each set of guide rods has a first spring on its outer side. The positioning plate has a protrusion on one side. The assembly frame has a connecting plate inside and a limit rod inside. The bottom end of the limit rod has a positioning post, which is inserted into a hole on the protrusion. A second spring is located on the outer side of the limit rod.

[0008] The lifting mechanism includes an electric push rod and a mounting housing. The electric push rod is disposed on the bottom inner wall of the testing platform, and the mounting housing is disposed at the top of the output end of the electric push rod. The rotating block is rotatably disposed inside the mounting housing, and the motor is disposed on one side of the mounting housing.

[0009] Furthermore, a mounting groove is provided on both the upper and lower surfaces of the rotating block, and an assembly block is provided inside both sets of mounting grooves. A support cylinder is provided at the top of one set of assembly blocks, and an electric clamp is provided at the bottom of the other set of assembly blocks.

[0010] Furthermore, a controller is provided at the top of the testing platform, multiple sets of heat dissipation holes are opened through one side of the testing platform, a housing is provided on one side of the testing platform, wherein the housing is located on the side corresponding to the heat dissipation holes, and a first through groove is opened through the top of the testing platform, wherein a rotating block is disposed in the first through groove.

[0011] Furthermore, two sets of second through slots are provided on the side of the rotating block, and the second through slots are connected to the mounting slots. Both sets of assembly blocks are provided with locking slots on their sides, and the locking plate is inserted into the locking slot through the second through slot.

[0012] Furthermore, two sets of limiting cylinders are fixedly provided at the bottom of the mounting shell, and guide columns are slidably provided inside the two sets of limiting cylinders. The bottom ends of the two sets of guide columns are fixedly connected to the bottom inner wall of the testing platform.

[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By incorporating a locking mechanism, the two sets of guide rods inside the assembly frame are both linear roller guides. These two sets of guide rods enable linear limiting and guiding movement of the locking plate. The two sets of guide rods, in conjunction with the first spring, allow the locking plate to pass through the second through slot and insert into the assembly block, achieving bidirectional elastic positioning of the assembly block. The positioning post at the bottom of the limiting rod is made of hard alloy. Utilizing the elastic push of the second spring on the outside of the limiting rod, the positioning post can insert into the protrusion to lock the locking plate. Compared to relying on bolt fixation, this effectively shortens the time for changing parts and tools. The structure is simple and practical, effectively improving testing efficiency.

[0014] 2. Equipped with a lifting mechanism and a turning mechanism, and driven by an electric push rod, the mounting shell can move up and down inside the testing table, allowing for adjustment of the height of the rotating block. By moving the electric push rod downward, the rotating block moves down and out of the first through slot to a suitable height. With the motor drive, the support cylinder and electric clamp can be switched. During the upward movement of the mounting shell, two sets of limiting cylinders can be moved upward outside the two sets of guide columns. The cooperation of the limiting cylinders and guide columns can improve the stability of the mounting shell during its up and down movement. Attached Figure Description

Detailed Implementation

[0017] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example

[0018] Please see Figure 1-6A multi-dimensional rapid testing platform for engineering mechanical properties includes: a testing table 1, with support frames 3 on the left and right sides of the top of the testing table 1, a cylinder 4 on the crossbeam of the support frame 3, a pressure plate 5 at the output end of the cylinder 4, and a cornering mechanism inside the testing table 1.

[0019] The corner mechanism includes a rotating block 10 and a motor 11. The rotating block 10 has rotating shafts on both sides. The output end of the motor 11 is connected to one of the rotating shafts of the rotating block 10. A mounting groove 12 is provided on both the upper and lower surfaces of the rotating block 10 for mounting the assembly block 14. There are two sets of assembly blocks 14. One set of assembly blocks 14 assembles the support cylinder 16, which is fixedly mounted on the upper surface of the assembly block 14. The other set of assembly blocks 14 assembles the electric clamp 26, which is fixedly mounted on the lower surface of the assembly block 14. The two sets of assembly blocks 14 have the same structure in other aspects. A locking groove 15 is provided on one side of each assembly block 14.

[0020] Please see Figure 5 and 6 The locking mechanism consists of two units, which are positioned opposite each other on the same side of the rotating block 10. Each locking mechanism includes an assembly frame 17 and a locking plate 20. The assembly frame 17 is fixedly connected to the side of the rotating block 10, such as by welding or by using screws or screw holes. Each assembly frame 17 includes two sets of guide rods 18, and a first spring 19 is provided on the outer side of each set of guide rods 18. A protrusion 25 is provided on one side of the locking plate 20, and a blind hole is provided on the protrusion 25. A connecting plate 21 is provided on the assembly frame 17, and a limit rod 22 is provided on the connecting plate 21. A positioning post 24 is provided at the bottom end of the limit rod 22, and the positioning post 24 is inserted into the blind hole of the protrusion 25. A second spring 23 is provided on the outer side of the limit rod 22. Two sets of second through slots 13 are provided on the side of the rotating block 10, and the positions of the second through slots 13 correspond to the positions of the locking slots 15 of the assembly block 14.

[0021] During assembly, after the assembly block 14 moves to the mounting slot 12, the positioning plate 20 is inserted into the second through slot 13, so that the positioning plate 20 passes through the second through slot 13 and is inserted into the positioning slot 15, thereby positioning the assembly block 14 and completing the rapid assembly of the corresponding support cylinder 16 and electric clamp 26.

[0022] Please see Figure 4 After the support cylinder 16 and the electric clamp 26 are assembled, they are installed on the mounting shell 9. The rotating shaft of the rotating block 10 is rotatably connected to the mounting shell 9. The mounting shell 9 is used to support the rotating block 10 and is driven by the motor 11, which enables the rotating block 10 to rotate on the mounting shell 9, changing the usage position of the support cylinder 16 and the electric clamp 26, and increasing the flexibility of the detection platform. Please see Figure 5The two sets of guide rods 18 inside the assembly frame 17 are both linear roller guides. The two sets of guide rods 18 can linearly limit and guide the movement of the positioning plate 20. The two sets of guide rods 18, together with the first spring 19, can make the positioning plate 20 pass through the second through slot 13 and insert into the assembly block 14, realizing bidirectional elastic positioning of the assembly block 14. The positioning post 24 at the bottom of the limiting rod 22 is made of hard alloy. With the elastic push of the second spring 23 on the outside of the limiting rod 22, the positioning post 24 can be inserted into the protrusion 25 to lock the positioning plate 20. Compared with bolt fixation, it can effectively shorten the film replacement time. The structure is simple and practical, and effectively improves the detection efficiency.

[0023] Please see Figure 2 , Figure 3 and Figure 4 As shown, a multi-dimensional engineering mechanical performance rapid testing platform includes a lifting mechanism comprising an electric push rod 27 and a mounting shell 9. The electric push rod 27 is fixedly installed on the bottom inner wall of the testing platform 1, and the mounting shell 9 is fixedly installed on the top of the output end of the electric push rod 27. Two sets of limiting cylinders 28 are provided at the bottom end of the mounting shell 9. Guide columns 29 are slidably connected inside the two sets of limiting cylinders 28, and the bottom ends of the two sets of guide columns 29 are fixedly connected to the bottom inner wall of the testing platform 1.

[0024] A first through groove 8 is provided on the top surface of the testing table 1, and a rotating block 10 is inserted into the first through groove 8. The first through groove 8 and the rotating block 10 are used in conjunction.

[0025] In use, the mounting shell 9 is raised or lowered inside the testing platform 1 by the electric push rod 27, adjusting the height of the rotating block 10. Lowering the electric push rod 27 causes the rotating block 10 to descend and disengage from the first through slot 8 to a suitable height. The rotating block 10 is then flipped by the motor 11, enabling the switching between the support cylinder 16 and the electric clamp 26. Raising the electric push rod 27 then raises either the support cylinder 16 or the electric clamp 26 on the rotating block 10 to the top surface of the testing platform 1 within the first through slot 8. The use of the limiting cylinder 28 and guide post 29 improves the stability of the mounting shell 9 during its raising and lowering process. A three-dimensional force sensor is built into the support cylinder 16, which can simultaneously measure the three-dimensional components Fx / Fy / Fz with a sampling rate of 1kHz. The two sets of electric clamps 26 can hold the test piece, enabling tensile performance testing.

[0026] Please see Figure 1 , Figure 2 and Figure 3As shown, a multi-dimensional rapid testing platform for engineering mechanical properties is provided. A controller 2 is mounted on the top surface of the testing platform 1. The controller 2 includes a human-machine interface and control buttons. A three-dimensional force sensor, a motor 11, an electric push rod 27, a cylinder 4, and an electric clamp 26 are electrically connected to the controller 2. The motor 11, electric push rod 27, cylinder 4, and electric clamp 26 are controlled by the controller 2. Multiple sets of heat dissipation holes 6 are formed through one side of the testing platform 1. A housing 7 is also provided on one side of the testing platform 1, with the housing 7 corresponding to one side of the heat dissipation holes 6. The heat dissipation holes 6 and the housing 7 are used in conjunction with the testing platform 1.

[0027] As a technical optimization of this utility model, the testing platform 1, as the basic load-bearing structure of the platform, is integrally cast from high-strength alloy steel. The controller 2 set at the top integrates PLC and HMI human-machine interface, supporting standard test process programming such as ISO 6892-1. The heat dissipation holes 6, together with the housing 7, form a dual-channel convection heat dissipation system, which can stabilize the working temperature of the hydraulic system at 40±2℃. The first through slot 8 adopts a precision guide structure with a taper of 1:50 to ensure that the positioning accuracy of the rotating block 10 reaches ±0.01mm.

[0028] Please see Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, a multi-dimensional engineering mechanical performance rapid testing platform is provided. The top of the testing platform 1 is provided with a support frame 3, which is used in conjunction with the testing platform 1. The top of the support frame 3 is provided with a cylinder 4, and the output end of the cylinder 4 is provided with a pressure plate 5, which is used in conjunction with the pressure plate 5.

[0029] As a technical optimization of this utility model, the pressure plate 5 is treated with tungsten carbide coating, and the vertical loading of 0-50kN is achieved by the cylinder 4. The electric clamp 26 integrates strain feedback function, and the clamping force can be steplessly adjusted between 50 and 500N, with a clamping repeatability accuracy of ±0.5μm.
