Technical Field
[0001] The utility model relates to the technical field of machinery, in particular to a tool for adjusting the position of a worm wheel of a worm gear mechanism. Background Art
[0002] The worm gear mechanism, also known as the worm gear mechanism, is a special type of gear mechanism evolved from the staggered axis helical cylindrical gear mechanism. It is mainly used to transmit motion and power between two staggered axes.
[0003] When adjusting the position of the worm wheel in the worm gear mechanism traditionally, it is necessary to first unscrew the fastening screws on the worm wheel seat that are used to fasten the worm wheel so that the worm wheel can move. When adjusting manually, it is necessary to ensure that the worm wheel can move axially or radially to change its meshing position with the worm, and then observe the meshing of the worm wheel and the worm to ensure the accuracy of the adjustment. When the worm wheel is adjusted to the appropriate position, it is necessary to immediately retighten the fastening screws to prevent the worm wheel from shifting during the transmission process. Adjusting the worm wheel often relies on manual operation, such as using wrenches, screwdrivers and other tools for fine-tuning, which is time-consuming and labor-intensive, affecting work efficiency.

It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.
[0022] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments of the following disclosure.
[0023] Embodiment 1, as Figure 1-Figure 4 As shown, the utility model provides a tool for adjusting the position of the worm gear of a worm gear mechanism, comprising a shell 1, a first motor 2 is fixedly connected to the outer surface of the shell 1, a slide groove 3 is provided on the inner surface of the shell 1, an output end of the first motor 2 passes through the shell 1 and extends to the inner side of the slide groove 3, a screw rod 4 is fixedly connected to the output end of the first motor 2, a sliding seat 5 is threadedly connected to the outer surface of the screw rod 4, an electric telescopic rod 6 is symmetrically fixedly connected to the bottom of the sliding seat 5, end surfaces of the two electric telescopic rods 6 are fixedly connected to support frames 8, outer surfaces of the two support frames 8 are fixedly connected to fixing rods 9, lower end surfaces of the two fixing rods 9 are fixedly connected to bearings 11, and a rotating shaft 12 is fixedly connected between the inner surfaces of the two bearings 11. A worm gear 13 is fixedly connected to the outer surface of the rotating shaft 12, a second motor 14 is fixedly connected to the outer surface of the outer shell 1 near the bottom, a distance sensor 7 is fixedly connected to the bottom of the sliding seat 5, and the distance sensor 7 is located above the worm gear 13. The output end of the second motor 14 penetrates the outer shell 1 and extends to the inside, and a worm 15 is fixedly connected to the output end of the second motor 14. The worm 15 is meshed with the worm gear 13, and the worm 15 is located below the worm gear 13. The positions of the worm gear 13 and the worm 15 match each other. A plurality of groups of positioning grooves 10 are equidistantly provided on the outer surface of the outer shell 1, and the size of the positioning groove 10 is equal to that of the rotating shaft 12. A limiting rod 16 is slidably penetrated and connected to the outer surface of the sliding seat 5, and the end face of the limiting rod 16 is fixed to the inner surface of the slide groove 3.
[0024] The effect achieved by the entire embodiment 1 is that when the position of the worm gear 13 needs to be adjusted, the second motor 14 on the outer surface of the housing 1 is first turned off to stop the worm 15 from moving, the electric telescopic rod 6 drives the support frame 8 to move upward, the support frame 8 drives the fixing rod 9 and the bearing 11, and the bearing 11 drives the worm gear 13 to move upward, so that the worm gear 13 and the worm gear 15 are completely separated. At this time, the first motor 2 is driven, and the first motor 2 drives the screw rod 4 in the driving groove 3, thereby driving the sliding seat 5, and the limit rod 16 limits the movement direction of the sliding seat 5, so that the sliding seat 5 drives the worm gear 13 to move in the horizontal direction. When the worm gear 13 moves to a suitable position, the rotating shaft 12 enters the positioning groove. 10, the electric telescopic rod 6 is lowered at this time, the electric telescopic rod 6 drives the bearing 11, and the bearing 11 drives the worm gear 13 to move downward until the rotating shaft 12 completely enters the bottom of the positioning groove 10. After the engagement is completed, the second motor 14 is driven to drive the worm 15 to rotate. Because the worm 15 and the worm wheel 13 are completely engaged, the worm wheel 13 will also start to rotate. The inner surface of the bearing 11 is connected to the rotating shaft 12, and the rotation of the worm wheel 13 is not affected when the rotating shaft 12 is working. The advantage of this method is that through the mutual cooperation of the first motor 2, the second motor 14, the sliding seat 5, and the electric telescopic rod 6, the operation of moving the worm wheel 13 is convenient, saving time and effort, and improving work efficiency.
[0025] Embodiment 2, as Figure 1-Figure 4 As shown, the output end of the first motor 2 is fixedly connected to a lead screw 4 , the outer surface of the lead screw 4 is threadedly connected to a sliding seat 5 , the bottom of the sliding seat 5 is fixedly connected to a distance sensor 7 , and the distance sensor 7 is located above the worm gear 13 .
[0026] The effect achieved by the entire embodiment 2 is that when the worm wheel 13 needs to adjust its position, the worm wheel 13 is first moved upward by the electric telescopic rod 6. When the worm wheel 13 is completely separated from the worm 15, the distance sensor 7 above the worm wheel 13 measures the position of the worm wheel 13 and measures the specific data of the worm wheel 13, thereby achieving precise control of the adjustment distance of the worm wheel 13 and facilitating the secondary meshing of the worm wheel 13 and the worm 15 after the position is moved.
[0027] Working principle: when the position of the worm gear 13 needs to be adjusted, first turn off the second motor 14 on the outer surface of the housing 1 to stop the worm 15 from moving, the electric telescopic rod 6 drives the support frame 8 to move upward, the support frame 8 drives the fixed rod 9 and the bearing 11, the bearing 11 drives the worm gear 13 to move upward, so that the worm gear 13 and the worm 15 are completely separated. When the worm gear 13 is completely separated from the worm 15, the distance sensor 7 above the worm gear 13 measures the position of the worm gear 13 and measures the specific data of the worm gear 13 to achieve precise control of the adjustment distance of the worm gear 13. At this time, drive the first motor 2, the first motor 2 drives the screw rod 4 in the slide slot 3 to drive the sliding seat 5, the limit rod 16 limits the movement direction of the sliding seat 5, so that the sliding seat 5 drives the worm gear 13 to move in the horizontal direction , and wait for the worm wheel 13 to move to the appropriate position. At this time, the rotating shaft 12 enters the positioning groove 10, and the electric telescopic rod 6 is lowered. The electric telescopic rod 6 drives the bearing 11, and the bearing 11 drives the worm wheel 13 to move downward until the rotating shaft 12 completely enters the bottom of the positioning groove 10. At this time, the meshing position is confirmed by the distance sensor 7. When the position is confirmed, the electric telescopic rod 6 drives the worm wheel 13 to be completely lowered, so that the worm wheel 13 and the worm 15 are meshed. After the meshing is completed, the second motor 14 is driven to rotate the worm 15. Because the worm 15 and the worm wheel 13 are completely meshed, the worm wheel 13 will also start to rotate. The inner surface of the bearing 11 is connected to the rotating shaft 12, and the rotation of the worm wheel 13 is not affected when the rotating shaft 12 is working. At this time, the adjustment of the position of the worm wheel 13 is completed.
[0028] The wiring diagram of the first motor 2, the electric telescopic rod 6, and the second motor 14 in the utility model belongs to the common knowledge in the field, and its working principle is a well-known technology. The model is selected according to the actual use. Therefore, the control method and wiring arrangement of the first motor 2, the electric telescopic rod 6, and the second motor 14 are no longer explained in detail.
