[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-Figure 2 The utility model provides an embodiment: a gear hobbing machine that is convenient for replacing a hob, comprising a workbench 1, a side wall of the workbench 1 is fixedly connected with an electric slide rail 2, a slide seat 3 is slidably connected inside the electric slide rail 2, a side wall of the slide seat 3 is fixedly connected with a fixing frame 4, a sliding rod 5 is fixedly connected inside the fixing frame 4, a side wall of the sliding rod 5 is fixedly connected with a fixing seat 6, a side wall of the sliding rod 5 is slidably connected with a slide plate 7, a side wall of the slide plate 7 is provided with a fixing component, a side wall of the fixing frame 4 is fixedly connected with a hydraulic rod 9, an output end of the hydraulic rod 9 is fixedly connected to a side wall of the slide plate 7 on one side, a side wall of the slide plate 7 is rotatably connected with a connecting plate 10, a side wall of the fixing seat 6 is rotatably connected with a connecting plate 2 11, one side of the connecting plate 10 is rotatably connected to the side wall of the connecting plate 2 11, a side wall of the slide plate 7 is provided with a hob body 12, a fixing component comprises a clamping plate 8, a side wall of the clamping plate 8 is fixedly connected to the side wall of the slide plate 7, and a side wall of the hob body 12 is slidably connected inside the clamping plate 8.

[0023] When the hob cutter equipment is used for a long time, the wear of the hob cutter body 12 will inevitably occur. When the wear reaches a certain degree, the performance and efficiency of the hob cutter body 12 will be affected. At this time, it needs to be replaced. By starting the hydraulic rod 9, the slide plate 7 on one side is pulled to move, thereby driving the connecting plate 10 on one side to move. One side of the connecting plate 10 will rotate on the slide plate 7, while driving the connecting plate 2 11 to rotate, and then driving the connecting plate 10 on the other side to deflect. Under the synergistic effect of the slide plate 7 and the connecting plates 10 and 11, the hob cutter body 12 loses the restriction of the clamping plate 8. At this time, the replacement of the hob cutter body 12 can be started, and one end of the new hob cutter body 12 is inserted into the inside of the clamping plate 8 on one side to ensure its stability. Then, the hydraulic rod 9 is started again to push the slide plate 7 on one side to move. Under the push of the hydraulic rod 9, the connecting plate 10 will deflect, and the connecting plate 10 on the other side will be driven to deflect through the connecting plate 2 11, so that the clamping plates 8 on both sides move to the middle to restrict the new hob body 12. In this way, the replacement of the hob body 12 is completed.

[0024] Reference Figure 3 The side wall of the workbench 1 is fixedly connected with an electric slide rail 22, and a slide seat 13 is slidably connected inside the electric slide rail 22. The side wall of the slide seat 13 is fixedly connected with a side frame 14, and a swivel seat 15 is arranged inside the slide seat 13. A screw rod 16 is rotatably connected inside the side frame 14, and a slider 18 is threadedly connected to the side wall of the screw 16. The side wall of the slider 18 is slidably connected inside the side frame 14. A motor 17 is fixedly connected to the side wall of the side frame 14, and the output end of the motor 17 is fixedly connected to one end of the screw rod 16. A positioning rod 19 is slidably connected inside the slider 18, and a limit plate 20 is fixedly connected to the side wall of the positioning rod 19, and a fixing cap 21 is threadedly connected to the side wall of the positioning rod 19.

[0025] When using this device, first, place the object to be processed on the top of the rotating seat 15, then start the motor 17, which will drive the screw 16 to rotate. As the screw 16 rotates, the slider 18 will slide up and down inside the side frame 14. The movement of the slider 18 changes the position of the positioning rod 19. When the bottom of the positioning rod 19 is pressed on the top of the object, it achieves the effect of fixing it.

[0026] Working principle: When using the equipment for work, first place the object to be processed on the top of the rotating seat 15, then start the motor 17 to drive the screw 16 to rotate, so that the slider 18 slides up and down inside the side frame 14, so as to change the position of the positioning rod 19, so that its bottom surface presses on the top of the object to fix it. After using the equipment for a long time, the hob body 12 will be worn and need to be replaced. At this time, the hydraulic rod 9 is started to pull the slide plate 7 on one side to move, which will drive the connecting plate 10 to move, and one side of the connecting plate 10 will slide on the slide. When the plate 7 rotates, the connecting plate 11 is driven to rotate, and the connecting plate 10 on the other side is driven to move at the same time. At this time, the hob body 12 loses the restriction of the clamping plate 8, and it is replaced at this time. One end of the new hob body 12 is inserted into the inside of the clamping plate 8 on one side. At this time, the hydraulic rod 9 is started again to push the slide plate 7 on one side to move, and the connecting plate 10 on the other side is deflected again, and the connecting plate 10 on the other side is driven to deflect through the connecting plate 11, so that the clamping plates 8 on both sides move inward, restricting the hob body 12, thereby completing the replacement of the hob body 12.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
