[0002] A tensile testing machine is a testing device used to test the mechanical properties of materials. It tests the mechanical properties of materials by applying tension. However, existing tensile testing machines have limited functions and can only perform tensile tests. They cannot meet the needs of testing other mechanical properties such as compression, bending, and shear. They also cannot quickly adapt to changes in different testing standards or sample types. When multiple mechanical properties need to be tested, multiple different testing devices need to be purchased or used, which increases the operation time and equipment investment costs.

Two sets of clamping components are provided and are movably disposed in the sliding groove. A clamping area is formed between the two sets of clamping components.

[0008] Through the cooperation of the transmission components and the bearing seat, when the movable clamp approaches or moves away from the fixed clamp, the cutting edge component moves away from and towards the mounting seat.

[0023] This application discloses a computer-controlled servo tensile testing machine. The support base has movable clamps for tensile testing and cutting blades for shear testing on both sides. The support base is connected to a rotating screw of a transmission component. When tensile testing is required, the material is clamped in two separate fixtures—one movable and one fixed—on a crossbeam. Rotating the screw moves the support base, causing the movable clamp to move away from the fixed fixture, thus applying tensile force to the material. When shear testing is required, the material is mounted on clamping components on a mounting base, ensuring the cutting blades are perpendicular to the material. Rotating the screw moves the support base towards the material, causing it to contact and cut it, thus detecting the shear force. The combination of the tensile and shear testing components allows for different testing methods to be performed on a single machine, solving the problem of existing tensile testing machines having only a single testing function and low efficiency.

[0044] Reference Figures 1-5 A computer servo tensile testing machine includes a base 1, a mounting frame 2, a transmission component 3, and a testing mechanism. The mounting frame 2 is mounted on the base 1 and includes columns 21 and crossbeams 22. Two sets of columns 21 are symmetrically distributed on the base 1. The two ends of the crossbeams 22 are connected to the two sets of columns 21 respectively. The crossbeams 22 are fixedly installed between the two sets of columns 21. The columns 21 have grooves 211 inside. The transmission component 3 is set in the grooves 211. The transmission component 3 includes a rotating lead screw 31 and a driver 32. The rotating lead screw 31 is rotatably mounted inside the column 21. A lead screw bearing seat is provided at the connection between the rotating lead screw 31 and the bottom of the column 21. The driver 32 is connected to the rotating lead screw 31 through a coupling. The driver 32 is a servo drive motor in the prior art, which provides power for the rotation of the rotating lead screw 31.

[0045] The testing mechanism includes a support 4, a tensile testing component 5, and a shear testing component 6. The tensile testing component 5 is used to test the tensile force of the material, and the shear testing component 6 is used to test the shear force of the material. The two ends of the support 4 are respectively mounted on the rotating screw 31. The tensile testing component 5 includes a fixed clamp 51 and a movable clamp 52. The fixed clamp 51 is set on the crossbeam 22 and has a pressure detection sensor. The movable clamp 52 is set on the side of the support 4 facing the fixed clamp 51. The fixed clamp 51 and the movable clamp 52 are respectively used to clamp the two ends of the material.

[0046] The shearing detection assembly 6 includes a cutting blade component 61, a mounting base 62, and a clamping component 63. The cutting blade component 61 is located on the other side of the support base 4. The mounting base 62 is located on the base 1 and between two sets of columns 21. The mounting base 62 has a sliding groove 621. Two sets of clamping components 63 are provided and are movably disposed within the sliding groove 621. A clamping area is formed between the two sets of clamping components 63. By moving the clamping components 63 within the sliding groove 621, the position of the clamping components 63 can be adjusted according to materials of different lengths, thereby improving the flexibility of the shearing detection assembly 6.

[0047] Through the cooperation of the transmission component 3 and the bearing seat 4, when the movable clamp 52 approaches or moves away from the fixed clamp 51, the cutting blade component 61 moves away from and approaches the mounting seat 62.

[0048] Based on the above structure, when tensile testing of materials is required, the two ends of the material are clamped onto the fixed clamp 51 and the movable clamp 52 respectively. Since the movable clamp 52 is mounted on the bearing seat 4 which is bonded to the rotating screw 31, when the bearing seat 4 moves the movable clamp 52 away from the fixed clamp 51, the material can receive an outward pulling force, thereby testing the tensile properties of the material. When shear compressive properties of the material are required, the two ends of the material are clamped and fixed onto the two sets of clamping components 63 respectively, so that the bearing seat 4 is tilted downwards. The position of seat 1 is moved. Since the cutting blade component 61 is located on the side of the bearing seat 4 facing the base 1, as the bearing seat 4 moves, the cutting blade component 61 gradually approaches the material and comes into contact with it. With the cooperation of the rotating screw 31, it moves again until the cutting blade component 61 applies vertical pressure to the material until it is cut. Through the cooperation of the tensile testing component 5 and the shearing testing component 6, multiple tests on the material can be achieved on one machine, so as to be applicable to different testing requirements and solve the problem of the single testing function of the existing tensile testing machine.

[0049] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The testing mechanism also includes a bending testing component 7. A guide rail 212 is provided on one side of the column 21. The bending testing component 7 includes a support base 71, a telescopic push rod component 72, and a bending component 73. The telescopic push rod component 72 can be an electric push rod in the prior art. The two ends of the support base 71 are provided with slots corresponding to the positions of the guide rail 212. Through the cooperation of the slots, the support base 71 can be moved and set on the guide rail 212.

[0050] The telescopic push rod component 72 is mounted on the support base 71 and is vertically distributed between the movable clamp 52 and the fixed clamp 51. The bending component 73 is mounted on the output end of the telescopic push rod component 72. With the cooperation of the support base 71, the telescopic push rod component 72 can be moved to the corresponding height according to the position of the material, thereby improving the flexibility of the bending detection component 7.

[0051] With the cooperation of the telescopic push rod component 72, the bending component 73 is brought closer to or away from the gap formed between the movable clamp 52 and the fixed clamp 51. When the material is located between the movable clamp 52 and the fixed clamp 51, the telescopic push rod component 72 drives the bending component 73 to apply vertical pressure to the material, and both ends of the material are fixed. As the bending component 73 moves with the cooperation of the telescopic push rod component 72, the degree of bending of the material gradually increases, thereby enabling the detection of the bending performance of the material.

[0052] In one embodiment, reference is made to Figure 1 , Figure 3 and Figure 6The clamping component 63 includes a placement seat 631, a clamping seat 632, and a screw 633. The clamping seat 632 is disposed on the top of the support seat 71 and is used to place materials. When the placement seat 631 is moved to the slide groove 621, the clamping seat 632 is located above the mounting seat 62.

[0053] The clamping seat 632 has a receiving groove 6321. The screw 633 is screwed and rotates on the clamping seat 632. Part of the screw 633 is located in the receiving groove 6321 and forms a clamping area with the bottom of the receiving groove 6321. By rotating the screw 633 on the clamping seat 632, the clamping area can be increased or decreased. By placing the two ends of the material to be tested into the receiving grooves 6321 of the clamping seats 632 on both sides, and fixing the material by the screw 633, the material is prevented from shaking when the pressure knife 613 comes into contact with the material.

[0054] The bottom of the screw 633 is provided with a clamping pad 6331, which is located in the receiving groove 6321. The clamping pad 6331 is made of rubber. The top of the screw 633 is provided with a handwheel 6332, which is located outside the clamping seat 632. The clamping pad 6331 is provided to avoid wear on the surface of the material when clamping it, thus protecting the material. The handwheel 6332 makes it easy for the operator to rotate the screw 633.

[0055] In one embodiment, reference is made to Figure 1 and Figure 5 The cutting component 61 includes a support 611, a pressure sensing component 612, and a pressing component 613. One end of the support 611 is connected to the bearing base 4, and the other end is connected to the pressure sensing component 612. The pressing component 613 is connected to the pressure sensing component 612, and the tip of the pressing component 613 faces the base 1. When the pressing component 613 comes into contact with the material, the pressure sensing component 612 can record the force borne by the pressing component 613 and convert it into a numerical value for display. The pressure sensing component 612 is a pressure sensor in the prior art.

[0056] The support member 611 consists of a fixed part 6111 and a movable part 6112. The fixed part 6111 is connected to the support base 4 and has a cavity extending to the outside. The movable part 6112 is movably disposed in the cavity and connected to the pressure sensing component 612. The overall length of the support member 611 is composed of the fixed part 6111 and the movable part 6112 located outside the fixed part 6111. In order to avoid the situation where the material thickness is too thin and the cutting blade 61 cannot meet the material, the overall length of the support member 611 is extended by the movement of the movable part 6112 in the fixed part 6111. This allows the cutting blade 61 to be used for materials of different thicknesses and improves the flexibility of use.

[0057] In one embodiment, reference is made to Figure 1 , Figure 2 and Figure 4 The bending detection component 7 also includes a pin 74. The guide rail 212 is provided with several spaced mounting holes 2121, and the support base 71 is provided with a through hole 711. The diameter of the through hole 711 is the same as the diameter of the mounting hole 2121. When the through hole 711 is aligned with one of the mounting holes 2121, the pin 74 passes through the through hole 711 and the mounting hole 2121. Since the support base 71 is movably mounted on the guide rail 212, in order to avoid the support base 71 shaking during operation and causing unnecessary movement on the guide rail 212, the pin 74 is used to limit the support base 71, preventing it from moving. Furthermore, the multiple mounting holes 2121 allow the support base 71 to be limited and supported at different heights.

[0058] In one embodiment, reference is made to Figure 1 and Figure 2 One of the columns 21 is equipped with a control console 8, which is electrically connected to the driver 32 and the telescopic push rod component 72. The control console 8 allows the operator to detect and adjust the output power of the driver 32 and the telescopic push rod component 72, and record the data, making it easy to observe and view the records.
