[0002] Gear broaching is a common metalworking method primarily used to manufacture various components, including gears, splines, and lead screws. During gear broaching, the workpiece is fixed, and the tool is rotated and moved to remove a certain depth of metal from the metal material, forming a tooth-shaped structure. However, existing gear broaching machines suffer from a complex workpiece replacement process, resulting in low efficiency in producing large batches of splines. The increased material removal increases cutting temperatures, exacerbating tool wear. Furthermore, waste chips from the blanks can easily cause blockages. To address these issues, a high-efficiency, long-life gear broaching machine with an anti-blocking function has been developed. Summary of the Invention

[0005] The main frame serves as an installation base for installing a positioning device, a tooth pulling device, a cooling device and a recycling box. The positioning device is used to position the blank, and the positioning device is located in the middle of the main frame, which facilitates the processing of the blank. The tooth pulling device is used to perform tooth pulling processing on the blank. The cooling device is used to cool the heat generated during the tooth pulling process, which can reduce tool wear and increase service life, while preventing waste chips from clogging and affecting the tooth pulling process. The recycling box is used to recycle waste water that has been used by the cooling device to cool the tooth pulling device, and to discharge the waste water in the main frame in a timely manner.

[0006] The main frame is provided with a driving cavity, a working cavity and a drainage opening. The driving cavity and the working cavity are communicated with each other, and the drainage opening is located at one side of the bottom of the driving cavity.

[0007] The driving chamber is used to realize the transmission process of the tooth-pulling device, and the working chamber is used to realize the processing process of the blank. The driving chamber and the working chamber are connected, so that the waste water in the working chamber can flow into the driving chamber and be discharged from the drainage opening. The drainage opening is located on one side of the bottom to prevent the waste water from accumulating and being unable to be discharged.

[0008] The positioning device includes a fixing frame, a positioning pin, a positioning groove, a positioning block and a slider. There are two fixing frames, positioning pins, positioning grooves, positioning blocks and sliders. The two fixing frames, positioning pins, positioning grooves, positioning blocks and sliders are symmetrically distributed on both sides of the tooth pulling device.

[0035] like Figures 1 to 3 As shown, the main frame 1 is provided with a driving chamber 11 , a working chamber 12 and a drainage opening 13 . The driving chamber 11 and the working chamber 12 are connected, and the drainage opening 13 is located on one side of the bottom of the driving chamber 11 .

[0037] like Figures 1 to 5As shown, the positioning device 2 includes a fixing frame 21, a positioning pin 22, a positioning groove 23, a positioning block 24 and a slider 25. There are two fixing frames 21, positioning pin 22, positioning groove 23, positioning block 24 and slider 25.

[0038] The fixing frame 21 serves as an installation base and is used to fix the positioning groove 23. The positioning pin 22 is used to fix the slider 25. The positioning groove 23 allows the positioning pin 22 and the slider 25 to move relative to each other, so that the blank can be positioned by controlling the position of the positioning block 24. Two sets of fixing frames 21, positioning pins 22, positioning grooves 23, positioning blocks 24 and sliders 25 are arranged on both sides of the tooth pulling device 3, which can make the positioning of the blank more accurate and the fixation more stable. The positioning block 24 is designed to be in an arc shape, which can better adapt to the shape of the blank and better fix the blank.

[0039] like Figures 1 to 3 As shown, the tooth pulling device 3 includes a first motor 31, a screw 32 and a mounting plate 33. There are two screws 32, and the two screws 32 are symmetrically distributed in the main frame 1. The fixed end of the first motor 31 is fastened to the main frame 1, the output end of the first motor 31 is fastened to one end of the screw 32, and the other end of the screw 32 is rotatably connected to the main frame 1. The mounting plate 33 is threadedly connected to the two screws 32, and the mounting plate 33 is arranged in the drive cavity 11.

[0040] The first motor 31 serves as a power source. The output end of the first motor 31 outputs torque to the screw 32, causing the screw 32 to rotate. The two screws 32 transmit the torque to the mounting plate 33, causing the mounting plate 33 to perform linear motion on the screw 32.

[0042] During material change: the receiving platform 37 and the gear knife column 36 are connected by keyway, and the gear knife column 36 and the connecting rod 35 are not connected;

[0043] When pulling teeth: the gear knife column 36 and the connecting rod 35 are threadedly connected, and the gear knife column 36 and the receiving platform 37 are not connected.

[0044] The second motor 34 serves as a power source, and the output end of the second motor 34 outputs torque to the connecting rod 35. The connecting rod 35 is used to connect and store the gear cutter column 36. The gear cutter column 36 is used to perform gear processing on the blank, and the receiving platform 37 is used to store the gear cutter column 36.

[0045] Furthermore, when changing materials, the gear cutter column 36 is stored on the receiving platform 37. After the blank is changed, the second motor 34 outputs torque to the connecting rod 35 for rotation. The receiving platform 37 limits the rotation of the gear cutter column 36 to only linear motion, so that the connecting rod 35 and the gear cutter column 36 are connected. When pulling teeth, the second motor 34 does not output torque, and the connecting rod 35 drives the gear cutter column 36 to move linearly to perform tooth pulling processing on the blank.

[0046] like Figures 1 to 5 As shown, the cooling device 4 includes a water tank 41, a first water pipe 42 and a second water pipe 43. The output end of the water tank 41 is connected to the first water pipe 42 and the second water pipe 43. The outlet of the first water pipe 42 is toward the driving chamber 11, and the outlet of the second water pipe 43 is toward the working chamber 12.

[0047] The water tank 41 is used to store cooling water, and the first water pipe 42 and the second water pipe 43 are used to transport cooling water to cool the tooth drawing device 3, reduce the wear of the gear tool column 36 of the tool, and extend the service life. The second water pipe 43 is provided with two water outlets facing the two positioning blocks 24 respectively, which can clean the waste chips generated by the blank during the tooth drawing process to prevent blockage caused by waste chips scraped off the blank.

[0048] like Figures 1 to 3 As shown, a water inlet opening and a drain opening 13 are provided on one side of the upper end of the recovery box 5 for communication.

[0049] The water inlet opening provided in the recovery box 5 is used to receive the waste water in the main frame 1 and discharge the waste water in the main frame 1 in a timely manner.

[0050] like Figure 3 As shown, the receiving platform 37 is provided with a groove toward the gear blade column 36 .

[0052] The working principle of the present invention is as follows: when the blank is subjected to tooth drawing processing and the material is changed, the gear cutter column 36 and the receiving platform 37 are key-connected to limit rotation but limit linear motion, and are not connected to the connecting rod 35. The blank is positioned through the positioning block 24 and the slider 25, and the positioning pin 22 fixes the slider 25. The first motor 31 is turned on, so that the first motor 31 outputs torque to the screw 32, so that the screw 32 rotates and drives the mounting plate 33 to perform linear motion, thereby driving the connecting rod 35 to perform linear motion. The second motor 34 is turned on, so that the second motor 34 outputs torque to the connecting rod 35, so that the connecting rod 35 rotates, and the connecting rod 35 passes through the blank to move toward the receiving platform 37 and the gear cutter column 36. Threaded connection, when tooth drawing is performed, the second motor 34 does not work, and the first motor 31 outputs torque to the screw 32, so that the screw 32 rotates and drives the mounting plate 33 to make a linear motion, thereby driving the connecting rod 35 to make a linear motion, and the connecting rod 35 drives the gear tool column 36 to move toward the blank to perform tooth drawing processing on the blank. During the processing, the first water pipe 42 and the second water pipe 43 will flow out cooling water to cool the tooth drawing device 3, wherein the two water outlets of the second water pipe 43 are aligned with the two positioning blocks 24 to prevent the waste scraps scraped from the blank from causing blockage. The waste water after use will flow into the recycling box 5 from the drainage opening 13 at the bottom, and the discharged waste water will be promptly treated. At this point, the tooth drawing process of the blank is completed.
