[0045] When the robot needs to be subjected to an impact dumping test, firstly, the robot's feet are stepped on the inside of the standing base 519 so that it stands on the surface of the pressure sensing plate 520, and the robot's legs are pressed against the surface of the leg plate 518. At this time, the pressure sensing plate 520 senses the pressure and sends an electrical signal to the controller 21. Then the controller 21 starts the two-way push rod 521 to drive the fixed caliper 522 to approach the robot's legs until it is clamped on the surface of the robot's legs. Then, the robot's waist is pressed against the surface of the waist plate 515, and the robot's waist and waist plate 515 are fixed with the restraint belt 516. Then, the robot can be fixed on the surface of the test frame 54, which is convenient for subsequent accurate acquisition. After the robot is hit, the tilting angle of the waist and legs is changed, and then the control parameters of the controller 21 are modified to control the rotation rate of the speed regulating motor 316. By starting the speed regulating motor 316, the transmission worm 43 can be driven to rotate, and then the transmission worm wheel 44 and the driving shaft 42 are driven to rotate between the two sets of support frames 41, thereby driving the driving gear 45 to rotate synchronously, and then the rotation of the driving gear 45 can drive the driven gear 46 to rotate. Under the action of the spline 47, the winding shaft 310 can be driven to rotate between the two sets of fixed frames 39, and then the winding rollers 38 at both ends of the surface can be driven to rotate synchronously, so that the impact rope 35 can be wound up. As the impact rope 35 is wound up, With the cooperation of reversing wheel 1 36 and reversing wheel 2 37, the push plate 33 can be pulled to move inside the impact box 31 and slide along the surface of the limit rod 32, so as to drive the impact head 34 to approach the surface of the robot. When the impact head 34 collides with the robot shell, the robot can be impacted to tilt, and the impact and dumping performance of the robot can be tested. By modifying the parameters of the controller 21 multiple times, the speed regulating motor 316 can be controlled to drive the impact head 34 to impact the robot at different rotation rates, thereby providing comprehensive and accurate data for the impact and dumping performance test of the robot. Different rotation rates mean that different strengths of impact can be generated. In this way, the tester can simulate It is necessary to simulate the different degrees of impact that the robot may suffer in various actual application scenarios to obtain more realistic and reliable test data. Secondly, obtaining test data of different intensities helps to gain a deeper understanding of the performance limits of the robot. By gradually increasing the impact intensity, it is possible to determine under what circumstances the robot will be damaged or its performance will degrade. This is crucial for optimizing the design of the robot and improving its reliability. It can help testers fully understand the robot's impact resistance and provide an important basis for the robot's optimized design and quality control. By gradually increasing the impact speed for testing, potential safety hazards can be discovered in a timely manner, such as loose parts and broken materials, so that improvements can be made before the product is put on the market.
[0046] It is worth noting that during this period, the movement of the push plate 33 can drive the positioning pulley 315 to slide in the positioning slide groove opened inside the impact box 31, which can not only position the movement of the push plate 33 and the impact head 34, ensuring that the force and direction of the impact are more accurate and the reliability of the test is improved, but also reduce friction resistance, greatly reducing the friction between the contact surface of the push plate 33 and the impact box 31, so that the push plate 33 and the impact head 34 can move more easily, and the movement of the push plate 33 is more stable and smooth, avoiding the jamming and instability caused by friction, and greatly reducing the energy required to drive the push plate 33 and the impact head 34, reducing energy consumption, as the push plate 33 drives the positioning pulley 315 to move When the push plate 33 contacts the surface of the blocking slider 313, it will push the blocking slider 313 to slide on the surface of the limit rod 32, and squeeze the spring 1 314 to deform and generate elastic force, thereby absorbing and dispersing the huge impact force generated by the push plate 33, preventing the push plate 33 from driving the positioning pulley 315 to make hard contact with the end of the impact box 31, causing damage due to the instantaneous strong force, and under the buffering effect of the spring 1 314, the impact of the robot on the impact head 34 will also be reduced, which can reduce damage to the robot's mechanical structures such as the shell and joints, and reduce the safety hazards such as splashing debris that may be generated during the collision. At the same time, the buffering effect of the spring is closer to the collision situation that the robot may encounter in the actual working environment, making the test results more valuable for reference.
[0047] Furthermore, the speed regulating motor 316 is used in conjunction with the reversing wheel 1 36 and the reversing wheel 2 37 to drive the impact rope 35 to drive the push plate 33 and the impact head 34 to perform an impact dumping performance test on the robot. Compared with the traditional cylinder impact test, the speed and strength can be controlled more accurately to adapt to different test requirements, and the impact force of the cylinder is avoided. It is difficult to accurately control the impact force of the cylinder due to factors such as air pressure stability, and a smoother starting and stopping process can be achieved, reducing the instantaneous impact on the robot and reducing the risk of damage. The cylinder may generate a large impact force when starting and stopping, causing greater stress on the structure and components of the robot. It has a lower maintenance cost and can work in a relatively harsh environment. The cylinder has high requirements on air quality, air pressure stability, etc., and may fail in some harsh environments.
[0048] When the impact head 34 hits the surface of the robot, the robot will tip over due to the impact, thereby driving the test frame 54 and the tipping frame 53 to flip over along the multiple sets of guide wheels 52 on the surface of the support seat 51, and the robot that is hit will transmit the impact force to the waist and legs. At this time, the robot's waist will transmit the impact force to the surface of the waist plate 515, and then the waist reset cylinder 514 will transmit and squeeze the pressure measuring device 1 at its end, and then measure the impact force on the robot's waist after the impact. Similarly, the pressure measuring device 2 at the end of the leg reset cylinder 517 can also be used to measure the robot's legs after the impact. The impact force borne by the waist and legs of the robot can provide an effective detection method for measuring the tilting angle after the robot's waist and legs are hit, which lays a foundation for accurately judging the posture and damage of the robot. The posture of the robot after the collision can be judged more accurately, and the two sets of pressure measuring devices 523 will transmit the measurement data to the controller 21 respectively, and then the controller 21 will receive and analyze the data, and then control the waist reset cylinder 514 and the leg reset cylinder 517 to open respectively. After opening, the waist reset cylinder 514 and the leg reset cylinder 517 will push the waist plate 515 and the leg plate 518 to move respectively, that is, The robot can be assisted and supported as a whole to help it recover its standing posture. During this period, the test frame 54 can be tilted to squeeze the force plate 513 toward one side of the fixed seat 55. The force plate 513 can be moved to squeeze the two sets of scissor-type hinged rods 511 under the action of the fan gear 512, and the angle can be changed, thereby driving the push-pull frame 510 to move toward one side of the fixed seat 55 synchronously, thereby driving the push block 56 to slide in the push groove opened inside the fixed seat 55, and squeezing the spring three 58 to deform and generate elastic force, thereby compressing the pressure sensor 57 to generate The controller 21 receives and analyzes the piezoelectric signal sent by the pressure sensor 57, so as to calculate the impact force received by the robot. It can accurately measure the impact force received by the robot at the moment of collision, and provide specific data support for evaluating the stability of the robot. Combined with the tipping angle of the robot, it can understand the robot's anti-tipping ability under impacts of different intensities, which is helpful to optimize the structural design and balance performance of the robot, reduce the errors caused by human factors, make the test results more reliable, and better design safety protection measures to reduce the damage and risks caused by the robot tipping over due to collision in actual use.
[0049] After the impact and dumping test of the robot is completed, the interlocking lever 413 is driven to flip inside the fixed plate 411 by starting the electric telescopic rod 412, so that the driven gear 46 can be driven to slide along the surface of the spline 47, and the rotating ring 48 is pushed to squeeze the spring 2 49 to deform and generate elastic force, so that the meshing connection between the driven gear 46 and the driving gear 45 can be released, thereby releasing the transmission between the drive shaft 42 and the winding shaft 310, and then starting the reset push rod 312, so that the reset push rod 312 pushes the blocking slider 313 to drive the push plate 33 to move in the opposite direction along the surface of the limit rod 32 inside the impact box 31, and the impact rope 35 can be pulled to move, so that the winding roller 38 drives the winding shaft 310 to rotate in the opposite direction between the two sets of fixed frames 39, so that the wound impact rope 35 can be released, and the push plate 33 and the impact head 34 is reset and waits for the next impact test. When the push plate 33 and the impact head 34 are reset, the electric telescopic rod 412 and the reset push rod 312 are closed. Under the action of the rebound force of the spring 49, the driven gear 46 and the active gear 45 can be re-engaged, and the transmission relationship between the winding shaft 310 and the driving shaft 42 can be connected again. Multiple impact tests can be performed quickly without frequent manual complex adjustments to re-establish the transmission relationship. The tester can focus more on observing and recording the test data, which greatly saves the preparation time between two impact tests, improves the overall test efficiency and the fluency of the test work, and provides richer data for the robot performance evaluation. For the operator, this automatic reset design makes the operation of the equipment easier, reduces the difficulty of operation and the possibility of errors, and improves the ease of use and maintainability of the equipment.
