[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model.

[0027] In this embodiment, refer to Figure 3The gear grinding mechanism 3 includes a mounting platform 301, a first servo motor 302, a second servo motor 303, a third servo motor 304, a fourth servo motor 305, and a fifth servo motor 306. A linear guide rail 307 is fixedly connected to the top of the mounting platform 301. A ball screw 308 is fixedly connected to the output end of the first servo motor 302. A mounting plate 309 is threaded onto the ball screw 308. A fixed seat 314 corresponding to the planetary reducer 310 and the electromagnetic brake 311 is fixedly connected to the top of the mounting plate 309. The second servo motor 303 and the third servo motor 304 are both fixedly connected to one end of the mounting plate 309.

[0028] In this embodiment, the output end of the third servo motor 304 is fixedly connected to a planetary reducer 310 and an electromagnetic brake 311. The output end of the electromagnetic brake 311 is fixedly connected to a fixed plate 312. Both sides of the fixed plate 312 are fixedly connected to balance cylinders 315. The output end of the balance cylinders 315 is externally rotatably connected to the high-speed electric spindle 313. The fourth servo motor 305 and the fifth servo motor 306 are fixedly connected to the top of the fixed plate 312. The output end of the fifth servo motor 306 is fixedly connected to the high-speed electric spindle 313.

[0029] In this embodiment, refer to Figure 4 The positioning mechanism 4 includes a worktable 401. The bottom of the worktable 401 is provided with multiple fastening ports. Two symmetrically arranged clamping cylinders 402 are fixedly connected to one side of the worktable 401. A positioning guide cylinder 407 corresponding to the clamping cylinder 402 is fixedly connected to the worktable 401. A pressure plate 403 is fixedly connected to the output end of the clamping cylinder 402. A rubber pad 408 is fixedly connected to the outer wall of the pressure plate 403. A truss 404 is fixedly connected to the top of the pressure plate 403. A sixth servo motor 405 and a seventh servo motor 406 are provided on the top of the truss 404.

[0030] In this embodiment, refer to Figure 5 The slicing mechanism 5 includes a fixed frame 501 and an eighth servo motor 502. A positioning guide rail 503 and a placement platform 504 are fixedly connected to one side of the fixed frame 501. A moving lead screw 505 is fixedly connected to the output end of the eighth servo motor 502. A sliding plate 506 is threaded onto the moving lead screw 505. A tilting cylinder 507 is fixedly connected to one end of the sliding plate 506. A slicing cylinder 508 is fixedly connected to the output end of the tilting cylinder 507. A vacuum suction cup mounting base 509 is fixedly connected to the output end of the slicing cylinder 508.

[0031] In this embodiment, the sawing machine: the eighth servo motor 502 drives the lead screw to move downwards, and the saw blade stops via a switch while the vacuum solenoid valve is opened (with a delay). Then, it moves upwards to a set position where the sawing cylinder actuates (the number of times can be set with a delay), detecting whether there is a saw blade (shared with the saw blade detection switch). An alarm is triggered if there is no blade. If there is a blade, it continues to move upwards to a set position where the rotary cylinder works and waits (the vacuum solenoid valve of the rotary cylinder resets after the truss picks up the blade). After grinding, the sawing process is repeated.

[0032] In this embodiment, the saw blade truss is driven by the sixth servo motor 405 and the seventh servo motor 406, which move the lead screw left, right, forward, and backward. The speed and position parameters need to be open for the blade to align with the sawing machine. After clamping the blade, the clamping cylinder 402 first moves laterally and then moves to the top of the worktable. The saw blade retrieval cylinder descends and then moves laterally to position itself (speed and position open). The sawing cylinder 508 is pre-loaded (power is cut off after pre-loading by the double-headed solenoid valve). After the clamping cylinder is de-energized, the saw blade retrieval cylinder is also de-energized. The seventh servo motor 406 moves backward a short distance, the saw blade retrieval cylinder descends for a second positioning, and then the sawing cylinder 508 is energized. The sixth servo motor 405 and the seventh servo motor 406 return to their set positions, wait for the saw blade to finish grinding, remove the saw blade, move it to the set position, and repeat the blade loading process.

[0033] In this embodiment, the gear grinding machine uses a safety door cylinder to drive the pick-and-place of the gear piece, de-energizing the safety door. During operation, the door opening and closing is detected by a switch before operation begins. The first servo motor 302 drives the ball screw 308 for transverse machining, the second servo motor 303 drives the lead screw for AB surface compensation, the third servo motor 304 tilts the axis (rotary axis with an external electromagnetic brake disc), the fourth servo motor 305 drives the lead screw to grind the gear, and the fifth servo motor 306 rotates the axis (rotary axis with an external electromagnetic brake disc). The standby origin of each axis can be set. For straight sawing, the first servo motor 302 and the fourth servo motor 305 are linked; for AB surface machining, the third servo motor 304 needs to be moved to a set position. During operation, the high-speed electric spindle 313 starts, and the cooling water is activated. The feed speed is divided into 2-3 segments (adjustable).

[0034] In this embodiment, the processing equipment can compensate for the depth and size of the teeth on the AB surfaces of the saw blade, accurately position the processing center, and improve product quality; the grinding wheel can rotate at an angle of ±60 degrees, making the processed saw blade sharper; the use of a high-speed electric spindle 313 shortens the processing cycle and improves efficiency; vertical processing provides better cooling, makes the equipment run more stably, and reduces water mist, achieving dry and wet separation inside the machine; and it can also realize intelligent remote control.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
