[0024] To make the technical means, technical features, utility model purpose and technical effects of this utility model easier to understand, the present utility model will be further described below with reference to specific illustrations.

[0025] like Figure 1 and Figure 2 The diagram shown is a schematic representation of the sample conveying device of the fully automatic tensile-torsion testing machine of this invention.

[0026] The fully automatic tensile-torsion testing machine sample conveying device of this embodiment includes a conveyor belt 1, sample holders 2, a robot arm 3, a first frame 7, and a second frame 12. The conveyor belt 1 is mounted on the second frame 12, and multiple sample holders 2 are evenly mounted on the conveyor belt 1. A conveyor motor 10 is fixed on the second frame 12, and a second conveyor wheel 9 is mounted on the output shaft of the conveyor motor 10. A first conveyor wheel 5 is rotatably mounted on the second frame 12 and is connected to the rotating shaft of the conveyor belt 1. A second conveyor chain 8 is mounted on the first conveyor wheel 5 and the second conveyor wheel 9. The conveyor belt 1 is driven by the conveyor motor 10, and the sample holders 2 move with the conveyor belt 1, placing the sample on the sample holder 2 for sample conveying. The robot arm 3 is mounted at the discharge end of the conveyor belt 1 and is mounted on the first frame 7. The robot arm 3 is provided with a support base 4, and a slide rail 6 is provided at the lower end of the support base 4. The slide rail 6 is fixedly mounted on the first frame 7.

[0027] The bottom of both the first frame 7 and the second frame 12 is equipped with support pads 11. The support pads 11 are height-adjustable support pads, which facilitate the adjustment of the overall height and level of the equipment to ensure the efficiency of sample transport.

[0028] like Figure 3-5 The diagram shown is a schematic representation of the sample holder of this invention.

[0029] The sample holder 2 shown has a placement groove 22 along the transverse direction of the frame. The placement groove 22 is "V" shaped and is used to place bolt samples. Limiting baffles 21 are provided on both sides of the sample holder 2 to limit the bolt samples and prevent them from sliding out of the sample holder 2. The sample holder 2 has a gripping groove 23 along the longitudinal direction. The gripping groove 23 is located in the middle of the sample holder 2 and extends longitudinally through the upper middle end of the placement groove 22. After the sample is transported to the designated position, the robot arm 3 grips the sample and transfers it to the testing machine position. The gripping groove 23 facilitates the robot arm 3 to grip the material. Usually, the bolt sample is placed in the middle of the placement groove 22. The gripping groove 23 is located in the middle of the sample holder to ensure that the force is stable after the robot arm 3 grips the sample and to prevent the sample from falling off when the robot arm transfers the material.

[0030] like Figure 6 and Figure 7 The diagram shown is a structural schematic of the robotic arm of this utility model.

[0031] The robotic arm 3 shown includes a translation base 38, a lifting base 33, and a gripper fixing base 313. The translation base 38 is fixed to the support base 4.

A fixing block is fixed on the lifting base 33. The fixing block is fixedly connected to the first transmission chain 36. The fixing block moves with the movement of the first transmission chain 36, and the lifting base 33 moves with the first transmission chain 36 via the fixing block. A translation slide rail 316 is fixed on the translation base 38, and a translation slider 39 is fixed on the lifting base 33. The translation slider 39 is slidably mounted on the translation slide rail 316, ensuring the stability of the lifting base 33 during translation.

[0032] A lifting motor 32 is fixed on the lifting base 33, and a lead screw 34 is installed at the output end of the lifting motor 32. A lifting block 312 is fixed on the gripper fixing base 313, and the lifting block 312 is threadedly connected to the lead screw 34. The lifting block 312 is driven by the lifting motor 32 to move up and down. A lifting slide rail 35 is fixed on the lifting base 32, and a lifting slider 310 is fixed on the gripper fixing base 313. The lifting slider 310 is slidably installed on the lifting slide rail 35 to ensure the stability of the gripper fixing base 313 when it moves up and down.

[0033] A bidirectional cylinder 314 is fixed on the clamping base 313, and a clamping hand 315 is installed on the bidirectional cylinder 314. The clamping direction of the clamping hand 315 corresponds to the installation direction of the sample holder 2, so as to ensure the clamping efficiency of the sample and improve the overall transfer efficiency of the sample.

[0034] The slide rail 6 is equipped with a traveling trolley 13, and the support seat 4 is fixed on the traveling trolley 13.
