Detailed implementation manners

[0033] The embodiments of the present invention will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals denote the same or similar elements or elements with the same or similar functions from beginning to end. The embodiments described below by referring to the drawings are exemplary and are intended to explain the present invention, and should not be construed as a limitation to the present invention.

[0034] Please refer to Figures 1 to 3 , in the first aspect, the present invention provides a detection device for the production and processing of inverters, including a detection rack 1, a detection device body 2, an installation mechanism 3 and a lifting mechanism. The lifting mechanism includes a turntable 4, a worm 5, a worm gear 6, a bidirectional screw 7, two sleeves 8, a transmission component and a lifting plate 9;

[0035] The turntable 4 is rotatably connected to the detection frame 1 and is located on the detection frame 1. The worm 5 is rotatably connected to the detection frame 1 and is fixedly connected to the turntable 4. The worm gear 6 meshes with the worm 5. The bidirectional screw 7 penetrates through the worm gear 6 and is fixedly connected to the worm gear 6 and is rotatably connected to the detection frame 1. The two sleeves 8 are respectively threadedly connected to the bidirectional screw 7 and are respectively located around the bidirectional screw 7. The transmission assembly is installed on the two sleeves 8. The lifting plate 9 is installed on the transmission assembly. The detection device body 2 is installed on the lifting plate 9. The installation mechanism 3 is installed on one side of the lifting plate 9 close to the detection device body 2.

[0036] In this embodiment, the detection frame 1 provides an installation condition for the lifting mechanism. The frequency converter to be detected can be fixed on the detection table through the installation mechanism 3, and the frequency converter on the installation mechanism 3 can be detected through the detection device body 2. When it is necessary to adjust the equipment on the detection table, rotate the turntable 4. The turntable 4 drives the worm 5 to rotate. The worm 5 drives the worm gear 6 to rotate. The worm gear 6 drives the bidirectional screw 7 to rotate. The bidirectional screw 7 drives the two sleeves 8 to approach each other. The two sleeves 8 drive the transmission assembly to move. The transmission assembly drives the lifting plate 9 to move to the side away from the detection frame 1 until the detection table moves to the preset height, and the height adjustment of the detection table can be completed, thus solving the problem that the existing detection device cannot be adjusted according to the actual needs of the staff.

[0037] Further, the transmission assembly includes two inclined rods 10 and a transmission plate 11. The two inclined rods 10 are respectively rotatably connected to the two sleeves 8 and are respectively located on the two sleeves 8. The transmission plate 11 is rotatably connected to the two inclined rods 10 and is fixedly connected to the lifting plate 9.

[0038] In this embodiment, when the two sleeves 8 move, they drive the two inclined rods 10 to rotate. When the included angle between the two inclined rods 10 and the two sleeves 8 becomes larger, the two inclined rods 10 drive the transmission plate 11 to move to the side away from the detection frame 1, thereby driving the lifting plate 9 to rise. When the included angle between the two inclined rods 10 and the two sleeves 8 becomes smaller, the two inclined rods 10 drive the transmission plate 11 to move to the side close to the detection frame 1, thereby driving the lifting plate 9 to lower.

[0039] Further, the lifting mechanism further includes a plurality of guide rods 12 and a plurality of sliding cylinders 13. The plurality of guide rods 12 are respectively fixedly connected to the detection frame 1 and are all located inside the detection frame 1. The plurality of sliding cylinders 13 are respectively slidably connected to the plurality of guide rods 12 and are respectively fixedly connected to the lifting plate 9.

[0040] In this embodiment, the plurality of guide rods 12 provide installation conditions for the plurality of sliding cylinders 13. When the lifting plate 9 moves, it drives the plurality of sliding cylinders 13 to slide on the plurality of guide rods 12. The plurality of sliding cylinders 13 guide and support the lifting plate 9 to improve the stability of the lifting plate 9 when it moves.

[0041] Further, the lifting mechanism further includes a moving plate 14, two fixed heads 15, a pull rod 16 and a return spring 17. The moving plate 14 is slidably connected to the detection frame 1 and is located inside the detection frame 1. The two fixed heads 15 are respectively fixedly connected to the moving plate 14 and respectively penetrate through the detection frame 1. The pull rod 16 is fixedly connected to the moving plate 14 and penetrates through the detection frame 1. The return spring 17 is fixedly connected to the moving plate 14 and is fixedly connected to the detection frame 1.

[0042] In this embodiment, the moving plate 14 provides installation conditions for the two fixed heads 15. Pulling the pull rod 16 can drive the moving plate 14 to move. The movement of the moving plate 14 can drive the two fixed heads 15 to move. The sliding cylinders 13 are each provided with a plurality of fixing holes. The fixed heads 15 can cooperate with the corresponding fixing holes to limit the sliding cylinders 13. The return spring 17 can reset the moving plate 14 by its resilience.

[0043] Further, the lifting mechanism further includes a guide rail 18 and two limit blocks 19. The guide rail 18 is fixedly connected to the detection frame 1 and is located inside the detection frame 1. The two limit blocks 19 are respectively slidably connected to the guide rail 18 and are respectively fixedly connected to the two sleeves 8 and are both located between the sleeve 8 and the guide rail 18.

[0044] In this embodiment, the guide rail 18 provides installation conditions for the two limit blocks 19. The two limit blocks 19 can guide and limit the two sleeves 8.

[0045] When it is necessary to adjust the equipment on the inspection table, the two fixing heads 15 on the moving plate 14 are moved out of the sliding cylinder 13 through the pull rod 16, and the turntable 4 is rotated. The turntable 4 drives the worm 5 to rotate, the worm 5 drives the worm gear 6 to rotate, the worm gear 6 drives the bidirectional screw 7 to rotate, the bidirectional screw 7 drives the two sleeves 8 to approach each other, the two sleeves 8 drive the two inclined rods 10 to rotate, the two inclined rods 10 drive the transmission plate 11 to move, and the transmission plate 11 drives the lifting plate 9 to move to the side away from the inspection frame 1 until the inspection table moves to a preset height. Then, the pull rod 16 is released, and the moving plate 14 is reset by the resilience of the return spring 17. The moving plate 14 drives the two fixing heads 15 to move into the preset fixing holes, and thus the height adjustment of the inspection table can be completed, solving the problem that the existing inspection device cannot be adjusted according to the actual needs of the staff.
