[0026] Example 1

[0027] like Figures 1-2 As shown, this invention proposes a gear processing device, which includes a processing chamber 1, a drive assembly 5, an adjustment assembly 2, a limiting assembly 4, and a milling cutter 3. The processing chamber 1 has an open front end and a platform at the bottom, with symmetrical semi-annular adjustment walls on both sides of the platform. The drive assembly 5 is located at the rear end of the processing chamber 1, with two sets of drive ends for driving synchronous and opposite rotational movements. Two sets of adjustment assemblies 2 are provided, with their bottoms driven by the two sets of drive ends of the drive assembly 5, sliding along the semi-annular adjustment walls in an arc-shaped trajectory, and their tops being retractable adjustment ends. The limiting assembly 4 is located on the platform and is used for positioning the gear to be processed and for adjusting its height and speed. The milling cutter 3 is cylindrical and is mounted on the adjustment ends of the two sets of adjustment assemblies 2, milling the gear from both sides.

[0028] Example 2

[0029] Based on the above embodiments, this embodiment further discloses the specific structures of the driving component 5, the adjusting component 2, and the limiting component 4.

[0030] like Figures 3-4As shown, the drive assembly 5 includes two sets of rotating columns 501. The rotating columns 501 are located at the center of the semi-annular adjusting wall and rotate through the wall of the processing chamber 1. One end of the rotating column 501 is keyed to a gear 502 located outside the chamber, and the other end of the rotating column 501 is connected to a drive rod 503. A mounting frame 506 is provided between the two sets of rotating columns 501. The mounting frame 506 is equipped with a motor, a lead screw 507 driven by the motor, and guide rods 508 arranged parallel to both sides of the lead screw 507. A lifting block 504 is provided on the lead screw 507 and threadedly connected to it. The lifting block 504 is slidably connected to the guide rods 508 and has racks 505 on both sides. The two sets of racks 505 are respectively meshed with the gears 502 on the corresponding sides. The drive rod 503 is connected to the limiting assembly 4. The working method of the drive assembly 5 is as follows: the motor drives the lead screw 507 to rotate, causing the lifting block 504 to move up and down, and the guide rods 508 guide its movement direction. The lifting block 504 moves, and the gear 502 is pushed by the rack 505, which drives the two sets of drive rods 503 to rotate, so that the limiting component 4 slides synchronously along the semi-circular adjustment walls on both sides in an arc-shaped trajectory, thereby adjusting the milling angle of the milling cutter 3.

[0031] like Figures 5-6 As shown, the adjustment assembly 2 includes a drive base 201; a U-shaped groove 101 is provided inside the semi-annular adjustment wall; the drive rod 503 has a hook-shaped structure, with the hook tail connected to the side wall of the rotating column 501, and the hook head moving in and out, passing through the groove 101, with its end connected to the drive base 201; a rotary drive component 1 and a cylinder 202 driven by the rotary drive component 1 are provided on the drive base 201; a detachable milling cutter 3 is provided on the telescopic rod of the cylinder 202. When the drive assembly 5 adjusts the angle of the milling cutter 3, the hook tail of the drive rod 503 rotates with the rotating column 501, and the hook head slides in the groove 101. The drive base 201 moves synchronously along an arc-shaped trajectory. Then, during the milling process, the position and rotation speed of the milling cutter 3 are adjusted through the cooperation of the drive component 1 and the cylinder 202 to meet the milling requirements of the gear to be machined.

[0032] It should be further explained that the bottom of the drive seat 201 is provided with ball bearings 204; a guide rail 102 for the ball bearings 204 to move is provided inside the semi-annular adjusting wall; two sets of guide rails 102 are provided, which are staggered with the two sets of slots of the slide groove 101. The smoothness of the movement of the drive seat 201 is improved by the ball bearings 204 rolling along the guide rail 102.

[0033] It should be further explained that a positioning groove 203 is provided on the telescopic rod of cylinder 202; a positioning strip 301 corresponding to the positioning groove 203 is provided on the wall of the mounting hole of the milling cutter 3. When installing the milling cutter 3, the positioning strip 301 is aligned with the positioning groove 203 and slid in, and the mounting hole locks the telescopic rod of cylinder 202, thus fixing the milling cutter 3. Multiple sets of positioning grooves 203 can be arranged radially, and the positioning strips 301 achieve the purpose of fixing the milling cutter 3 by corresponding one-to-one with the positioning grooves 203.

[0034] like Figures 7-8 As shown, the limiting assembly 4 includes a second drive base 610. The second drive base 610 is located at the bottom of the machining chamber 1, and a second drive component and a second cylinder 601 driven to rotate by the second drive component are mounted on it. The cylinder body of the second cylinder 601 rotates through the platform, and a limiting post 602 is provided on the end of the telescopic rod. Multiple sets of limiting components are provided along the outer periphery of the upper end of the limiting post 602, and multiple sets of positioning frames 605 are provided along the outer periphery of the lower end. The limiting component includes a third cylinder 603 located on the limiting post 602 and a limiting frame 604 connected to the telescopic rod end of the third cylinder 603. The limiting frame 604 has an arc-shaped structure. When the limiting assembly 4 is working, the gear to be processed is placed on the limiting post 602 until the bottom of the gear abuts against the positioning frame 605. Then, the third cylinder 603 activates the limiting frame 604 to extend and position it on the inner wall of the shaft hole of the gear to be processed, making it coaxial with the limiting post 602. This ensures the stability of the gear to be processed during the milling process and facilitates the control of machining accuracy.

[0035] It should be further explained that the structure of drive component two is the same as that of drive component one; drive component two includes motor two 613 and gear two 612 connected to the main shaft of motor two 613; gear three 611 is keyed to the cylinder body of cylinder two 601; gear three 611 meshes with gear two 612. When drive component two is working, the rotational speed of the gear to be processed is adjusted through the meshing connection between gear three 611 and gear two 612. Drive component one works similarly.

[0036] Example 3

[0037] Based on the above embodiments, this embodiment further discloses the cooling and cleaning related structures of gear processing equipment.

[0038] like Figures 1-2 As shown, a liquid storage tank 7 and a spray head 6 connected to the liquid storage tank 7 are installed on the top of the machining chamber 1; two sets of spray heads 6 are arranged corresponding to the left and right milling points. The liquid storage tank 7 stores cooling and cleaning fluid, such as machine oil, which is sprayed onto the tooth surface of the gear to be machined during the milling process. On the one hand, it achieves a cooling effect to prevent gear deformation, and on the other hand, it washes and cleans the debris generated during milling.

[0039] like Figure 7As shown, a waste liquid recovery box 606 is fitted around the outer periphery of the limiting post 602; a collection ramp 608 is provided at the top of the waste liquid recovery box 606, and an interception platform 607 is provided around its outer periphery; a filter screen is provided on the collection ramp 608, and it is connected to the drain outlet 609 inside the waste liquid recovery box 606. After the cooling and cleaning fluid finishes its work, it flows into the waste liquid recovery box 606 along the limiting post 602. First, under the action of centrifugal force, the heavier debris slides to the bottom interception platform 607, and the liquid enters the waste liquid recovery box 606 when it passes through the drain outlet 609, achieving the purpose of solid-liquid separation. Subsequently, the debris and cooling and cleaning fluid can be sorted and recycled. The recycling operation is simple and convenient, reducing the pollution of the platform.

[0040] Example 4

[0041] This embodiment presents a method for using the aforementioned gear processing equipment, with the following steps:

[0042] S1. Position the gear to be processed on the limiting component 4: Place the gear to be processed on the limiting post 602 until the bottom of the gear abuts against the positioning frame 605; then the cylinder 3 603 starts the limiting frame 604 to extend out of the inner wall of the shaft hole of the gear to be processed for positioning, so that it is coaxial with the limiting post 602.

[0043] S2. Select a suitable milling cutter 3 according to the parameters of the gear machining design, and install it on the adjusting end of the adjusting component 2: slide the positioning strip 301 into the positioning groove 203, and lock the telescopic rod of the cylinder 202 in the mounting hole to complete the fixing of the milling cutter 3.

[0044] S3. Adjust the angle and position of the milling cutter 3 to bring it close to the gear to be machined, and complete the tool setting: the lead screw 507 rotates, causing the lifting block 504 to move up and down, the gear 502 is pushed by the rack 505, which drives the two sets of drive rods 503 to rotate. The hook tail of the drive rod 503 rotates with the rotating column 501, and the hook head slides in the slide groove 101; the drive seat 201 moves synchronously, and in conjunction with the extension and retraction of the cylinder 202, the milling cutter 3 is adjusted.

[0045] S4. By rotating the milling cutters 3 on both sides, meshing teeth are formed on both sides of the gear to be processed; the gear to be processed rotates and milling continues until the preliminary processing of the entire tooth surface is completed, and a cylindrical gear is obtained.

[0046] S5. Next, the adjusting component 2 slides along the semi-circular adjusting wall, driving the milling cutters 3 on both sides to rotate. The milling angle gradually increases, further processing the cylindrical tooth surface. The cone angle is adjusted to the set value to obtain a bevel gear.

[0047] S6. During the milling process, the spray head 6 sprays the tooth surface of the gear to be machined, which on the one hand achieves the cooling effect to avoid gear deformation, and on the other hand washes and cleans the chips generated during milling.

[0048] S7. The cooling and cleaning fluid flows into the waste liquid recovery box 606 along the limiting post 602.

[0049] It should be further noted that the arc trajectory angle created by the milling cutter 3 is 0° ≤ a < 90°. When machining cylindrical gears, the milling cutter 3 is always located at the bottom of the arc trajectory, with its axis parallel to the axis of the gear to be machined. When machining bevel gears, the milling cutter 3 moves upward from the bottom of the arc trajectory until the cone angle of the gear to be machined reaches the specified value.

[0050] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
