Description

Technical Field

[0001] This utility model relates to the field of pressure testing machine technology, and more specifically, to a fully automatic pressure testing machine with robotic arm sample delivery. Background Technology

[0002] The fully automatic compression testing machine is mainly used for compressive strength testing of concrete samples with specifications of 100x100x100, 150x150x150 and 200x200x200. It is an ideal testing equipment for building inspection departments, quality supervision departments and large industrial and mining enterprises.

[0003] The current technical system is not perfect. After the test is completed, the broken sample fragments are scattered everywhere. The cleaning work mainly relies on manual labor. After the equipment stops running, the staff must use simple tools to clean up the fragments bit by bit. The process is tedious and time-consuming. Moreover, the sharp edges of the fragments can easily cut people, posing a safety hazard. In addition, in the traditional way, the operator must manually place the sample to be tested inside the press. This step is difficult to connect smoothly with the subsequent automated testing process, which seriously hinders the improvement of overall testing efficiency and cannot meet the current demand for large-scale and high-frequency sample testing. It has become a bottleneck that urgently needs to be overcome in the development of the industry. Utility Model Content

[0029] Specifically, the cleaning component enables automatic debris removal. A rotating shaft 9 is rotatably connected to the inner wall of the push plate 8, and a rotating rod 10 is fixedly connected to the outer surface of the shaft 9. Brush bristles 11 are provided on the outer surface of the rotating rod 10. When the shaft 9 rotates, the rotating rod 10 rotates accordingly, thereby driving the brush bristles 11 to clean the debris. One end of the shaft 9 passes through the outer surface of the push plate 8 and is fixedly connected to a gear 12. A slider 7 is fixedly connected to the outer surface of the push plate 8. A groove 6, adapted to the slider 7, is provided on the inner wall of the pressure test chamber 2. The cooperation between the push plate 7 and the slide 6 allows the push plate 8 to slide smoothly within the pressure test chamber 2. A rack 13 is fixedly connected to the inner wall of the pressure test chamber 2. The outer surface of the gear 12 is connected to the lower surface of the rack 13 via a transmission connection. This transmission connection allows the push plate 8 to drive the rotating shaft 9 and the rotating roller 10 to rotate during movement through the interaction of the gear 12 and the rack 13. A rear guard plate 14 is fixedly connected to the rear side of the pressure test chamber 2 at the rear of the pressure frame 1.

The lower end of the second shaft 18 is slidably connected to the inner side wall of the limiting slide groove 19. When the bidirectional hydraulic cylinder 15 works and the telescopic rods at both ends retract, they drive the first shaft 16 to move. The first shaft 16 is driven by the scissor rod 17. The second shaft 18 moves and slides within the limiting groove 19, thereby pushing the push plate 8 forward. During the forward movement of the push plate 8, the rotating shaft 9 and the rotating roller 10 are rotated by the transmission action of the gear 12 and the rack 13, which sweeps the debris in the pressure test chamber 2 in the direction of the push plate 8. The debris is pushed out from the inclined funnel 20 and falls onto the upper surface of the transmission belt 21, which then transports it to the waste bin 22, thus facilitating the automatic cleaning of debris in the pressure test chamber 2.

[0030] Please see Figure 1 , Figure 6 and Figure 7 The sample delivery assembly includes a robot guide rail 23, an articulated robot 24 is slidably connected to the upper surface of the robot guide rail 23, a connecting block 28 is detachably connected to the end of the articulated robot 24, a gripper 29 is slidably connected to the inner wall of one end of the connecting block 28, two grippers 29 are provided and symmetrically arranged, and a barcode scanning camera 30 is fixedly connected to the upper side of the two grippers 29 on the inner wall of the end of the connecting block 28.

[0031] Specifically, the automatic feeding test is achieved through a sample feeding component. The articulated robot 24 is slidably connected to the robot guide rail 23. This connection method allows the articulated robot 24 to move precisely along the guide rail. The connecting block 28 is detachably connected to the end of the articulated robot 24. This design facilitates the replacement of the connecting block 28 according to different test requirements to adapt to test blocks 26 of different shapes or sizes. There are two grippers 29 symmetrically arranged on the inner wall of one end of the connecting block 28. They are installed on the connecting block 28 by sliding connection. This connection method allows the grippers 29 to open and close flexibly to adapt to the clamping requirements of test blocks 26 of different sizes. The two grippers 29 are located on the inner wall of the end of the connecting block 28. A barcode camera 30 is fixedly connected to the upper middle side. When the articulated robot 24 moves the connecting block 28 to the rear of the test block 26, the barcode camera 30 can scan the barcode label 27 affixed to the outer surface of the test block 26 to obtain relevant data of the test block 26. In use, the articulated robot 24 slides on the robot guide rail 23, driving the connecting block 28 and the gripper 29 at its end to move, so that the gripper 29 can clamp the test block 26 at different positions. Before clamping, the barcode camera 30 first scans the barcode label 27 and automatically records the data of the test block 26. Then the gripper 29 clamps the test block 26 and sends it into the pressure test chamber 2 for testing, thereby achieving the purpose of automatic feeding test.

[0032] In summary, when using the entire device for material pressure testing, firstly, the test block 26 to be tested is placed on the pressure testing chamber 2, and the corresponding barcode label 27 is affixed to its outer surface. After preparation, the entire device is started. The articulated robot 24 slides precisely on the robot guide rail 23, and its end drives the connecting block 28 to move behind the test block 26. At this time, the barcode camera 30 scans the barcode label 27 to obtain various basic data of the test block 26. After data acquisition, the gripper 29 clamps the test block 26 and sends it into the pressure testing chamber 2. Then, the hydraulic cylinder 3 starts working, pushing the pressure sensor 4 and pressure plate 5 down to apply pressure to the test block 26. During the pressure application process, the pressure sensor 4 records various pressure values ​​in real time. When the test block 26 is crushed, it means that the test is complete. At this point, the bidirectional hydraulic cylinder 15 begins to work, with its two telescopic rods retracting. Through the coordinated action of the first shaft 16, the scissor linkage 17, the second shaft 18, and the limiting slide groove 19, it drives the push plate 8 to move forward. Simultaneously, the gear 12 and the rack 13 cooperate to drive the rotating shaft 9 and the rotating roller 10 to rotate. During the rotation, the bristles 11 on the outer surface of the rotating roller 10 sweep smaller fragments and powders forward, while the push plate 8 pushes larger fragments forward. These fragments eventually fall from the inclined funnel 20 onto the upper surface of the transmission belt 21. The transmission belt 21 runs to the left, transporting the fragments into the waste bin 22. The entire test process achieves fully automated operation without manual intervention, greatly improving work efficiency and avoiding potential safety hazards from manual cleaning of fragments, making operation more convenient.

[0033] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model.
