DETAILED DESCRIPTION

[0024] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0025] like Figure 1 , Figure 3 As shown, a robot trajectory testing device includes a base 1, four annularly distributed inclined ladders 2 are fixedly connected to the outer side of the base 1, a shock absorbing mechanism 3 is fixedly connected to the inner lower surface of the base 1, a placing table 4 is fixedly connected to the upper side of the shock absorbing mechanism 3, and a receiving mechanism 5 is rotatably connected to the upper side of the placing table 4.

[0026] It should be noted that the inclined ladder 2 is used to facilitate the transportation of the robot to the placement table 4. The inclined ladder 2 and the placement table 4 can be directly provided with connecting parts, so that the inclined ladder 2 can be removed from the base 1 for easy transportation.

[0027] like Figure 2 , Figure 3As shown, the shock absorbing mechanism 3 includes a first spring 31, the lower side of the first spring 31 is fixedly connected to the inner lower surface of the base 1, and a number of first springs 31 are evenly distributed on the inner lower surface of the base 1, the upper side of the first spring 31 is fixedly connected to a mechanism platform 32, and a number of annularly distributed placement seats 33 are fixedly connected to the inner lower surface of the mechanism platform 32 near the edge, a connecting seat 35 is placed on the bottom upper surface of the placement seat 33, and the lower surface of the placement platform 4 is fixedly connected to the upper surface of the connecting seat 35.

[0028] It should be noted that the first spring 31 is a shock-absorbing spring having a damping component thereon. The first spring 31 is used to reduce the vertical force exerted on the placement table 4 due to external vibration.

[0029] like Figure 3 , Figure 4 As shown, the side walls of the plurality of placement seats 33 away from the mechanism platform 32 are all fixedly connected with a second spring 34 .

[0030] It should be noted that the second spring 34 is a shock-absorbing spring having a damping component thereon. The second spring 34 is used to reduce the lateral force exerted on the placement table 4 due to external vibration.

[0031] like Figure 4 As shown, a plurality of evenly distributed balls 36 are rotatably connected to the upper surfaces of the bottom walls of the plurality of placement seats 33 .

[0032] It should be noted that the ball 36 is used to reduce the friction between the connecting seat 35 and the placing seat 33 to prevent the friction from affecting the shock absorbing effect of the second spring 34 .

[0033] like Figure 2 , Figure 5 As shown, the receiving mechanism 5 includes a turntable 51, the inner side of which is rotatably connected to the outer side of the boss on the upper surface of the placement table 4, and a plurality of hydraulic telescopic rods 52 are fixedly connected to the upper surface of the turntable 51 near the edge, and a signal receiving plate 53 is fixedly connected to the upper end of the hydraulic telescopic rod 52.

[0034] It should be noted that the robot to be detected is placed in the middle of the upper surface of the placement table 4, and an infrared signal generator is placed at its moving end. The signal receiving board 53 is used to receive the signal sent by the infrared signal generator to detect the running trajectory of the moving end of the robot. The hydraulic telescopic rod 52 can drive the signal receiving board 53 to move up and down so that the signal can still be detected when the moving end is at a higher position.

[0035] like Figure 5 , Figure 6As shown, a gear ring 54 is fixedly connected to the lower surface of the placement table 4 near the edge, a motor 55 is fixedly connected to the rear side of the upper surface of the turntable 51, and the output end of the motor 55 is fixedly connected to the first bevel gear 56, and the first bevel gear 56 is located on the lower side of the turntable 51, and a worm 57 is rotatably connected to the boss on the lower side of the turntable 51 near the rear side, and a second bevel gear 58 is fixedly connected to the outer wall of the worm 57 near the left end, the left side of the first bevel gear 56 is meshed and connected with the upper side of the second bevel gear 58, and the rear side of the gear ring 54 is meshed and connected with the outer wall of the worm 57.

[0036] It should be noted that the motor 55 drives the first bevel gear 56 to rotate, the first bevel gear 56 drives the second bevel gear 58 to rotate, and the second bevel gear 58 drives the worm 57 to rotate when it rotates. When the worm 57 rotates, it meshes with the ring gear 54, and the ring gear 54 is fixedly connected to the placement table 4 so that it is stationary, causing the worm 57 to revolve around the ring gear 54, causing the turntable 51 to rotate.

[0037] The working principle of the utility model is as follows: first, the first spring 31 is a shock-absorbing spring, which contains a damping component. The first spring 31 is used to reduce the vertical force exerted on the placement table 4 due to external vibration. The second spring 34 is a shock-absorbing spring, which contains a damping component. The second spring 34 is used to reduce the lateral force exerted on the placement table 4 due to external vibration. The ball 36 is used to reduce the friction between the connecting seat 35 and the placement seat 33 to prevent the friction from affecting the shock-absorbing effect of the second spring 34. The first spring 31 and the second spring 34 absorb the force exerted on the placement table 4 due to external vibration, so that the placement table 4 remains as stable as possible. Only the receiving mechanism 5 and the robot are in the same state to reduce the influence of external vibration on it and reduce experimental errors. Finally, the robot to be detected is placed in the middle of the upper surface of the placement table 4, and an infrared signal generator is placed at its moving end. The signal receiving board 53 is used to receive the infrared signal. The signal sent by the infrared signal generator is received to detect the running trajectory of the robot's moving end. The hydraulic telescopic rod 52 can drive the signal receiving plate 53 to move up and down, so that the signal can still be detected when the moving end is at a higher position. The motor 55 drives the first bevel gear 56 to rotate, and the first bevel gear 56 drives the second bevel gear 58 to rotate. When the second bevel gear 58 rotates, it drives the worm 57 to rotate. When the worm 57 rotates, it meshes with the ring gear 54, and the ring gear 54 is fixedly connected to the placement table 4 so that it is stationary, causing the worm 57 to revolve around the ring gear 54, causing the turntable 51 to rotate, and the signal receiving plate 53 is driven up and down by the hydraulic telescopic rod 52. The motor 55 drives the signal receiving plate 53 to rotate, so that the signal receiving plate 53 can receive signals in multiple directions to obtain the moving path of the signal on the signal receiving plate 53, and the robot's motion trajectory is obtained to detect whether it meets the standard.
