[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figure 1-5 As shown, a gear hobbing fixture for machining gears comprises a base 1, a fixing seat 4 arranged above the base 1, a positioning seat 5 fixed to the top surface of the fixing seat 4, and a positioning sheet 6 attached to the top surface of the positioning seat 5, a positioning screw 7 passes through the middle of the positioning sheet 6, and the positioning screw 7 is threadedly connected to the inner side of the positioning seat 5;

[0024] When in use, it is only necessary to put the gear to be processed on the outside of the positioning seat 5, then press the positioning plate 6 against the top surface of the gear, and pass the positioning screw 7 through the middle of the positioning plate 6, so that the positioning screw 7 is threaded into the inside of the positioning seat 5 until the nut of the positioning screw 7 is tightly against the positioning plate 6. In this way, the positioning plate 6 can be used to press and fix the gear, which is convenient for the installation of the gear.

[0025] Further, refer to Figure 1 and Figure 2 As shown, it is worth noting that a height adjustment component is provided below the fixing seat 4;

[0026] The height adjustment component includes a fixed sleeve 2 with an open top and vertically arranged below the fixed seat 4, and a movable plate 3 slidably arranged inside the fixed sleeve 2. One end of the movable plate 3 passes through the fixed sleeve 2 and is fixedly connected to the bottom surface of the fixed seat 4. A plurality of sockets are equidistantly provided on the plate body of the movable plate 3. A screw is threadedly provided on the side wall of the fixed sleeve 2, and the screw is inserted into one of the sockets.

[0027] By setting the height adjustment component, the movable plate 3 is raised and lowered so that the movable plate 3 slides inside the fixed sleeve 2, and the height position of the fixed seat 4 can be appropriately adjusted. Then, the knob screw is turned so that the screw is inserted into the corresponding socket, and the movable plate 3 can be locked to ensure the stability of the fixed seat 4 at a fixed height position.

[0028] However, in practice, the above real-time method can only adjust the height position of the fixing seat 4. Once the base 1 is installed by bolts, it is found that there is a certain position or distance deviation between the installation position of the fixing seat 4 and the position of the hob. The device is often unable to quickly adjust the position of the fixing seat 4 in terms of position or distance, so that the bolts need to be removed manually before the fixing seat 4 can be adjusted. The actual adjustment has certain limitations, which seriously affects the practicality of the device.

[0029] For this purpose, refer to Figure 1-4 As shown, it is worth noting that a multi-directional adjustment component is provided between the height adjustment component and the base 1;

[0030] The multi-directional adjustment component includes a movable cylinder 8 which is vertically rotatably arranged on the top surface of the base 1 and a slide 9 which is transversely fixed in the top opening of the movable cylinder 8. A slider 10 is slidably arranged in the slide 9, and a fixed sleeve 2 is fixed on the top surface of the slider 10.

[0031] By setting up the multi-directional adjustment components, rotating the movable cylinder 8 and sliding the slider 10, the directional and spacing deviations between the fixed seat 4 and the hob can be quickly adjusted, which effectively reduces the limitations and improves the application range of the device.

[0032] Further, refer to Figure 2-4As shown, it is worth noting that a vent pipe 13 located below the slider 10 is also transversely fixed to the inner side of the movable cylinder 8, a lifting clamp is provided between the vent pipe 13 and the slider 10, a positioning clamp is provided between the vent pipe 13 and the base 1, and a gas injection sleeve 16 fixedly connected to the top surface of the base 1 is provided on the outer circumference of the movable cylinder 8, and a gas injection assembly is provided on one side of the wall of the gas injection sleeve 16, and one end of the vent pipe 13 passes through the movable cylinder 8 and passes into the gas injection sleeve 16;

[0033] By setting the lifting and lowering cards, the positioning cards and the gas injection components, after sliding the slider 10 and rotating the movable cylinder 8 to complete the adjustment of the orientation and spacing of the fixed seat 4, the gas injection components are used to increase the pressure inside the gas injection sleeve 16 and the ventilation pipe 13. In this way, the lifting and lowering cards and the positioning cards are simultaneously subjected to pressure to quickly achieve the fixing effect of the movable cylinder 8 and the slider 10. There is no need to manually fix the two separately after the movable cylinder 8 rotates or the slider 10 slides, which further improves the convenience of the device, saves time and improves efficiency.

[0034] Further, refer to Figure 3 and Figure 4 As shown, it is worth noting that the lifting fixture includes a fixed tooth plate 11 fixed to the bottom surface of the slider 10, a positioning tooth plate 12 slidably arranged below the fixed tooth plate 11, and a fixed square tube 14 connected and fixed to the pipe body of the vent pipe 13, and a movable block 15 fixedly connected to the bottom surface of the positioning tooth plate 12 is slidably arranged on the inner side of the fixed square tube 14, and a first spring is fixed between the bottom end of the movable block 15 and the inner wall of the bottom end of the vent pipe 13;

[0035] The positioning fixture includes a fixing sleeve 17 connected and fixed to the body of the vent pipe 13 and a positioning column 18 slidably arranged inside the fixing sleeve 17. A plurality of positioning holes 19 adapted to the positioning columns 18 are arranged around the top surface of the base 1. One end of the positioning column 18 corresponds to one of the positioning holes 19. A second spring is fixed between the other end of the positioning column 18 and the inner wall of the top end of the vent pipe 13.

[0036] When the air injection assembly is used to increase the internal pressure of the ventilation pipe 13, the fixed square tube 14 and the fixed sleeve 17 can be pressurized synchronously, and then the positioning column 18 and the movable block 15 slide on the inside of the fixed sleeve 17 and the fixed square tube 14 respectively under the action of air pressure, so that the positioning column 18 slides down and penetrates into the corresponding positioning hole 19, and the positioning tooth plate 12 slides up to engage with the fixed tooth plate 11, thereby achieving the tightening effect of the slider 10 and the movable cylinder 8 synchronously.

[0037] Further, refer to Figure 3As shown, it is worth noting that the gas injection assembly includes a gas injection cylinder 20 connected and fixed to the wall of the gas injection sleeve 16 and a piston 21 slidably arranged in the gas injection cylinder 20, and an extrusion screw 22 is arranged at the end of the gas injection cylinder 20, and the extrusion screw 22 is threadedly inserted into the gas injection cylinder 20 and is rotatably connected to the piston 21;

[0038] The knob squeezes the screw 22 so that the squeezing screw 22 penetrates into the gas injection cylinder 20 under the threaded structure and pushes the piston 21 to slide. In this way, the piston 21 can squeeze the internal gas of the gas injection cylinder 20 during the sliding process, so that the internal gas of the gas injection cylinder 20 passes into the gas injection sleeve 16, thereby increasing the air pressure in the gas injection sleeve 16 and the ventilation pipe 13.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
