Then, the telescopic hydraulic cylinder drives the clamping seat to move down and the two clamping cylinders drive the rotating cylinder to clamp the gear. The clamping seat is then reset to directly above the tilting box. The first transmission motor drives the two chucks to rotate 90 degrees synchronously through the tilting box to keep the tilting box in a horizontal state. The chucks facilitate the feeding and clamping of the gears clamped by the two clamping cylinders. The tilting box drives the two chucks to rotate, which facilitates the clamping of gears on both chucks. The installation status of the tilting box is monitored by an electronic level. 2. This invention uses a positioning cylinder to drive an insert plate to be inserted into the positioning groove and two positioning holes on the positioning plate. The positioning plate and the insert plate are then interlocked to provide positioning support for the tilting box, maintaining its stability during gear machining. The second X-axis linear module, Y-axis linear module, and Z-axis linear module in the three-axis drive mechanism can adjust the cutting tool inside the tilting box in three axes, facilitating gear machining. After single-sided gear machining is completed, the tilting box is rotated again, and the clamping seat uses a clamping cylinder to tilt the gear. After tilting, the gear is clamped again by a chuck, achieving double-sided gear machining. Attached Figure Description

The output ends of the clamping cylinders 205 pass through the clamping seat 204 and are fixedly connected to the rotary cylinders. The two clamping cylinders 205 are symmetrically installed relative to the telescopic cylinder 203. The telescopic cylinder 203 slides back and forth in the X direction along the axis of the first X-direction linear module 202. By installing the material conveying mechanism 2, it is convenient to automatically load and unload large-sized gears and flip them during double-sided processing.

[0021] Please see Figures 2 to 5 A three-axis drive mechanism 3 is installed inside the material conveying mechanism 2. The three-axis drive mechanism 3 includes a second X-axis linear module 301. Y-axis linear modules 302 are fixedly installed at both ends of the second X-axis linear module 301. Z-axis linear modules 303 are fixedly installed on the adjacent side of the two Y-axis linear modules 302. Rotary seats 304 are slidably connected to the outer sides of the two Z-axis linear modules 303. Two tool holders 305 are rotatably connected to the adjacent ends of the two rotary seats 304. A guide beam 306 is slidably connected to the upper end of the Z-axis linear module 303. The two Y-axis linear modules 302... The Z-axis linear module 303, the rotary seat 304, and the guide beam 306 are all symmetrically installed relative to the center of the second X-axis linear module 301. The Y-axis linear module 302 slides reciprocally in the X direction along the axis of the second X-axis linear module 301. The Z-axis linear module 303 slides reciprocally in the Y direction along the axis of the Y-axis linear module 302. The rotary seat 304 slides reciprocally in the Z direction along the axis of the Z-axis linear module 303. The second X-axis linear module 301 and the two guide beams 306 are all fixedly connected to the mounting bracket 201. The three-axis drive mechanism 3 facilitates the three-axis linkage machining of the gears.

[0022] Please see Figures 3 to 8 A flipping synchronous machining mechanism 4 is installed in the middle of the three-axis drive mechanism 3. The flipping synchronous machining mechanism 4 includes a transverse mounting base 401, which is fixedly connected to the mounting frame 201. Supporting frames 402 are fixedly installed at both ends of the transverse mounting base 401. Positioning cylinders 403 are fixedly installed on the far sides of the two supporting frames 402. A first drive motor 404 is installed directly above one of the positioning cylinders 403. A plate 410 is installed at the output end of the positioning cylinder 403. A flipping box 405 is installed at the output end of the first drive motor 404. The two supporting frames 402 are positioned relative to the flipping box 405. 5 are symmetrically installed. The first drive motor 404 is fixedly connected to one of the support frames 402. The output end of the first drive motor 404 passes through one of the support frames 402 and is fixedly connected to the flip box 405. Both sides of the flip box 405 are rotatably connected to chucks 407. The inner side of the two tool holders 305 is provided with tools. The two tool holders 305 are coaxial with the chucks 407. Two second drive motors 411 are fixedly installed on the inner side of the middle part of the flip box 405. The two chucks 407 are symmetrically installed with respect to the flip box 405. The flip box 405 drives the gears to flip through the chucks 407 to facilitate double-sided processing. The output end of the second drive motor 411 passes through the tilting box 405 and is fixedly connected to the chuck 407. The surface of the chuck 407 is provided with multiple circumferentially arranged jaws. The chuck 407 is used to clamp the gear. Positioning plates 406 are fixedly installed at the four corners of the tilting box 405. Each positioning plate 406 has two positioning holes 409 in the middle. A positioning groove 408 is provided between two adjacent positioning holes 409. The output end of the positioning cylinder 403 passes through the support frame 402 and is fixedly connected to the insert plate 410. The insert plate 410 is away from the positioning cylinder. One side of cylinder 403 is inserted into the inner side of positioning groove 408 and two positioning holes 409. The inner wall of the tilting box 405 is equipped with an electronic level. The electronic level is electrically connected to the first drive motor 404 and the two positioning cylinders 403 through a control circuit, so that the installation status of the tilting box 405 can be monitored by the electronic level. When the tilting box 405 is in a vertical position, the positioning plate 406 and the insert plate 410 are interlocked to achieve positioning support for the tilting box 405, so as to maintain the stability of the tilting box 405 during the gear processing.

[0023] In summary, when machining large-sized gears, the gears are transferred and placed onto the material transfer seat 206 using a robotic arm. With the power on, the telescopic cylinder 203, through the first X-axis linear module 202, moves the clamping seat 204 and clamping cylinder 205 above the material transfer seat 206. Then, the telescopic cylinder 203 moves the clamping seat 204 downwards, and the two clamping cylinders 205 drive the rotary cylinder to clamp the gear. The clamping seat 204 is then reset to directly above the tilting box 405. The telescopic cylinder 203, through the clamping cylinder 205 and the rotary cylinder, again moves the gear downwards. Simultaneously, the first drive motor 404 is started, so that the first drive motor 404, under the support of the support frame 402, drives the two chucks 407 to rotate 90 degrees through the tilting box 405, keeping the tilting box 405 in a horizontal state. Then, the chucks 407 facilitate the loading and clamping of the gears held by the two clamping cylinders 205. Then, the above operation is repeated on the clamping seat 204, and the tilting box 405 drives the two chucks 407 to rotate, so that the gears can be clamped on both chucks 407. After the gears are clamped on the two chucks 407, the tilting box 405 is reset. An electronic level is installed on the inner wall of the tilting box 405 to monitor the installation status of the tilting box 405. When the tilting box 405 is in a vertical position, the positioning cylinder 403 is activated, which drives the insert plate 410 to insert into the positioning groove 408 and two positioning holes 409 on the positioning plate 406. The positioning plate 406 and the insert plate 410 are interlocked to achieve positioning support for the tilting box 405 and maintain the stability of the tilting box 405 during gear processing. The second X-axis linear module 301, Y-axis linear module 302 and Z-axis linear module 303 in the three-axis drive mechanism 3 can adjust the tool in the flip box 405 in three axes, which makes it easier to use the tool to process the gear. After the gear is processed on one side, the flip box 405 is rotated again, and the clamping seat 204 uses the clamping cylinder 205 to flip the gear. After flipping, it is clamped again by the chuck 407 to realize the double-sided processing operation of the gear.
