[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0028] Example 1:

[0029] like Figure 1-5As shown, a gear machining accuracy testing device includes a housing 1. A testing platform 7 and a feeding bracket 8 are fixedly connected to the inside of the housing 1. A stabilizing bracket 14 is fixedly connected above the feeding bracket 8. A timing belt 13 is slidably connected to the inside of the feeding bracket 8. Multiple support rods 19 are rotatably connected above the timing belt 13. A support plate 21 is fixedly connected above the support rods 19. A testing piece 18 is fixedly connected above the support plate 21. A rotating gear 20 is fixedly connected below the support rods 19. A heater 25 and a rack 22 are fixedly connected above the stabilizing bracket 14. The heater 25 can blow out airflow at 20℃±5℃. A lower air outlet 24 and an upper air outlet 23 are fixedly connected to the air outlet of the heater 25. One side of the rotating gear 20 meshes with the rack 22.

[0030] Before testing, the test piece 18 can be manually installed on top of the support plate 21. This allows the support rod 19 to move from the outside of the feeding bracket 8 to the inside near the testing table 7 as the timing belt 13 moves. When the test piece 18 moves between the lower air outlet 24 and the upper air outlet 23, it can be conditioned by the 20℃±5℃ airflow blown by the warm air blower 25. To ensure uniform temperature of the test piece 18, the rotating gear 20 contacts the rack 22 during its movement, causing the upper test piece 18 to rotate, resulting in more even airflow and temperature control. The support plate 21 has multiple ventilation holes to allow more airflow to contact the area below the test piece 18.

[0031] In this embodiment, a feeding motor 11 is fixedly connected to the lower part of the feeding bracket 8, and synchronous pulleys 12 are rotatably connected to both ends of the upper part of the feeding bracket 8. A synchronous belt 13 is driven and connected to the synchronous pulleys 12 on both sides. The power output end of the feeding motor 11 is fixedly connected to one side of the synchronous pulley 12. The synchronous pulley 12 and the synchronous belt 13 can be in the form of chain sprocket drive or belt drive. When the feeding motor 11 drives the synchronous pulley 12 on one side to rotate, it can drive the synchronous belt 13 to slide, thereby driving the multiple support rods 19 above to move simultaneously.

[0032] In this embodiment, a recycling bin 10 is fixedly connected to the inner side of the box 1, a feed inlet 2 is opened on the outer side of the box 1, and a control panel 3 is fixedly connected to one side of the outer wall of the box 1.

[0033] The recycling bin 10 is used to recycle the tested parts 18 after testing is completed. The feed inlet 2 is used to install gears on the outer support plate 21. The control panel 3 can control the operation of the electronic components inside the device. The control method is existing technology.

[0034] In this embodiment, a detection motor 9 is fixedly connected below the detection platform 7, and a detection support platform 29 is fixedly connected to the power output end of the detection motor 9. The detection support platform 29 is rotatably connected above the detection platform 7, and the detection motor 9 can drive the detection support platform 29 above to rotate and perform multiple detections on the gears.

[0035] In this embodiment, an electric screw 26 is fixedly connected to one side of the housing 1. An L-shaped bracket 27 is threadedly connected to both sides of one end of the electric screw 26. One side of the L-shaped bracket 27 is slidably connected to the top of the detection table 7. A detection probe 28 is fixedly connected to one end of the L-shaped bracket 27. The detection probe 28 is existing technology and will not be described in detail here.

[0036] The motor end of the electric screw 26 is installed on one side of the housing 1. When the motor end is working, it can drive the screw end to rotate. In this way, the double-headed screw can drive the L-shaped brackets 27 on both sides to move inward at the same time, and use the detection probe 28 to contact the detection piece 18 for detection.

[0037] In this embodiment, a robotic arm 15 is fixedly connected above the detection platform 7, and a vacuum suction cup 17 is fixedly connected to the end of the robotic arm 15. One end of the vacuum suction cup 17 is fixedly connected to the air inlet of a vacuum pump 16 through a pipe. One side of the vacuum pump 16 is fixedly connected to the detection platform 7. The robotic arm 15 can vacuum-adsorb the test piece 18 after the temperature has been adjusted and place it on the detection support platform 29 for detection. After the detection is completed, the test piece on the detection support platform 29 is picked up and finally placed in the recycling box 10.

[0038] In this embodiment: Before testing, the test piece 18 can be manually installed above the support plate 21. This allows the support rod 19 to move from the outside of the feeding bracket 8 to the inside near the testing platform 7 as it moves with the synchronous belt 13. When the test piece 18 moves between the lower air outlet 24 and the upper air outlet 23, it can be conditioned by the 20℃±5℃ airflow blown by the warm air blower 25. To ensure uniform temperature of the test piece 18, the rotating gear 20 contacts the rack 22 during its movement, causing the upper test piece 18 to rotate, resulting in more even airflow and temperature control. The support plate 21 has multiple ventilation holes to allow more airflow to contact the area below the test piece 18.

[0039] The synchronous pulley 12 and the synchronous belt 13 can be in the form of chain sprocket drive or belt drive. When the feeding motor 11 drives the synchronous pulley 12 on one side to rotate, it can drive the synchronous belt 13 to slide, thereby driving the multiple support rods 19 above to move simultaneously.

[0040] The recycling bin 10 is used to recycle the tested parts 18 after testing. The feed inlet 2 is used to install gears on the outer support plate 21. The control panel 3 can control the operation of the electronic components inside the device. The control method is existing technology. The testing motor 9 can drive the testing support platform 29 above to rotate and test multiple parts of the gears.

[0041] The motor end of the electric screw 26 is installed on one side of the housing 1. When the motor end works, it can drive the screw end to rotate. In this way, the double-headed screw can drive the L-shaped brackets 27 on both sides to move inward at the same time. The detection probe 28 is used to contact the detection piece 18 for detection. The robotic arm 15 can vacuum adsorb the detection piece 18 after the temperature is adjusted and place it on the detection support platform 29 for detection. After the detection is completed, the detection piece on the detection support platform 29 is picked up and finally placed in the recycling box 10.

The temperature detection component 4 is preferably an infrared detection component, which can detect whether the temperature adjustment is completed by the infrared characteristics of the detection component 18.

[0045] In this embodiment, an image detection component 5 and a light ring 6 are fixedly connected to the inner wall of the top of the housing 1. The image detection component 5 can perform precision detection to determine whether there are shape defects by capturing image data, and the light ring 6 can prevent the image detection from being affected by the angle of the light source.
