[0057] The clamping member 407 includes a detection clamping cylinder 418 installed on the assembly part 415, and a fixed matching seat 419 and a movable matching seat 420 are provided on one side of the detection clamping cylinder 418, and the movable matching seat 420 is drivingly connected to the output shaft of the detection clamping cylinder 418, and the fixed matching seat 419 and the movable matching seat 420 are commonly connected to a clamping head 421 through a connecting rod structure.

[0058] When in use, the third transfer mechanism 701 transfers the formed matching rack 201 workpiece to the detection slide 405, and the detection clamping cylinder 418 drives the clamping head 421 to clamp the rack workpiece through the connecting rod structure. In the initial state, the assembly part 415 of the detection slide 405 is always against the detection slide 405 due to the force of the second spring member 414. In this state, the stopper 416 is in the initial position and is a distance away from the signal unit 417. At this time, the detection slide 405 is driven to slide along the track 404 (the matching principle of the detection slide 405 and the track 404 is the same as the matching principle of the linear slide rail and the linear slider in the prior art) and passes through the two detection plates 408. The two detection plates 408 detect the first guide part 205 and the second guide part 206 on the front and rear sides of the matching rack 201 workpiece;

[0059] Specifically, when the first guide portion 205 and the second guide portion 206 are bent into place, the first guide portion 205 and the second guide portion 206 correspond to the first guide groove 208 and the second guide groove 209 of the two detection plates 408, respectively. Therefore, the detection slide 405 with the matching rack 201 can smoothly pass through the detection plate 408 without getting stuck. At this time, there will be no large displacement between the detection plate 406 and the detection slide 405 (at most there will be a small friction displacement). Therefore, the stopper 416 of the detection plate 406 does not The signal unit 417 will be blocked, and the signal unit 417 will not send a signal (that is, the current workpiece is a qualified workpiece). When the detection base 403 conveys the workpiece matching the rack 201 to the right place, the fourth transfer mechanism 702 transfers the product to the tooth opening unit 401 for tooth opening. A fifth transfer mechanism 708 is provided on one side of the tooth opening unit 401. The second substrate 4 is provided with a collection port at the fifth transfer mechanism 708, and a collection box is provided below the collection port. The fifth transfer mechanism 708 transfers the rack workpiece with completed tooth opening to the collection port and drops it into the collection box.

[0060] When there is a bending error between the first guide portion 205 and the second guide portion 206, friction and jamming will occur between the detection slide 405. The jamming between the two causes the detection plate 406 to overcome the force of the spring member and slide radially along the detection base 403. Since there is only a slight deviation, the detection slide 405 is reset to the initial position after the workpiece of the matching rack 201 is out of contact with the detection plate 408, and the detection base 403 still transfers the workpiece of the matching rack 201 to the place where it cooperates with the fourth transfer mechanism 702. However, in the above process, when jamming occurs between the workpiece of the matching rack 201 and the detection plate 408, the detection plate 406 drives the stopper 416 to move and blocks the signal unit 417, and the external signal receiving unit receives the signal (that is, the current product accuracy is unqualified). When the detection base 403 transports the workpiece of the matching rack 201 to the place where it is in place, the fourth transfer mechanism 702 transfers the unqualified product to the workpiece recovery place 402, specifically, a workpiece recovery port is opened on the second substrate 4 and a recovery box is preset below the workpiece recovery port.

[0061] The gear opening unit 401 includes a gear opening base 449, on which a gear opening material placement seat 450 is slidably arranged, and the gear opening material placement seat 450 includes two positioning slides 451, between which a workpiece fixing seat 452 is commonly connected, and a gear opening material clamping cylinder 453 is installed on the upper surface of one of the positioning slides 451, and two linear drive components 454 are correspondingly installed on the front and rear sides of the gear opening base 449 away from one end of the fourth transfer mechanism 702, and a gear shaping cutter 455 is installed on the output shaft of the linear drive component 454;

[0062] Two corresponding slide grooves 422 are provided on the upper surface of the toothed base 449, and matching screw rods 423 are rotatably arranged in the two slide grooves 422. One end of the two matching screw rods 423 extends through the toothed base 449 to the outside and is connected to a driven bevel gear 424. A gear shaft 425 is rotatably arranged on the side of the toothed base 449 away from the fourth transfer mechanism 702. A transmission bevel gear 1 426, a transmission bevel gear 2 427 and a transmission bevel gear 3 428 are fixedly mounted on the outer ring of the gear shaft 425. The transmission bevel gear 1 426 and the transmission bevel gear 2 427 are respectively driven and meshed with the driven bevel gears 424 of the two matching screw rods 423. The transmission bevel gear 3 428 is connected to an external driving source to drive the gear 203 shaft to rotate forward or reverse.

[0063] When in use, an external driving source (servo motor) drives the transmission bevel gear 3 428 to rotate, and the transmission bevel gear 3 428 drives the gear 203 shaft to rotate, thereby driving the transmission bevel gear 1 426 and the transmission bevel gear 2 427 to rotate, driving the two matching screw rods 423 to rotate synchronously in the forward or reverse direction, so as to drive the toothed material placement seat 450 to slide back and forth radially along the toothed base 449;

[0064] During operation, the toothed material placement seat 450 is driven to slide radially along the toothed base 449 and toward the fourth transfer mechanism 702. The fourth transfer mechanism 702 clamps the detected mating rack 201 workpiece to the workpiece fixing seat 452. The workpiece fixing seat 452 is pre-formed with a landing groove. The mating rack 201 workpiece is placed in the landing groove. The output shaft of the toothed clamping cylinder 453 is connected to the clamping piece 407. The toothed clamping cylinder 453 drives the clamping piece 407 to move toward the workpiece fixing seat 452 and clamps the mating rack 201 workpiece to limit the position. At this time, the two linear drive components 454 drive the gear inserting cutter 455 to teeth the workpiece.

[0065] An oil discharge port 429 is formed on the top surface of the toothed base 449 at one end away from the fourth transfer mechanism 702. A support plate 430 is connected to the oil discharge port 429 via a connecting rod, and an oil supply tank 431 is installed on the support plate 430. A plurality of oil outlet nozzles 432 are installed on the front and rear sides of the upper end of the oil supply tank 431. The lower end of the oil supply tank 431 extends through and extends to the bottom of the support plate 430 and is connected to an oil supply system via a pipeline.

[0066] The oil supply system includes an oil return tank 433, a sieve filter tank 434 and a branch guide tank 435. The oil return tank 433 is installed below the second substrate 4 and is located at a position corresponding to the oil discharge port 429. A sieve cavity 436 is formed inside the sieve filter tank 434. An extension cavity 437 is formed on the inner circumference of the sieve cavity 436. A filter cover 438 is provided in the extension cavity 437, and a dirt storage interval is formed between the filter cover 438 and the extension cavity 437. The sieve filter tank 434 has a first pipeline 439, a second pipeline 440 and a third pipeline 441. The outer end of the first pipeline 439 is connected to the oil return tank 433 and the other end is connected to the dirt storage interval. One end of the second pipeline 440 is connected to the dirt storage interval and the other end is connected to the branch guide tank 435. One end of the third pipeline 441 is connected to the sieve cavity 436 and the other end is connected to the branch guide tank 435.

[0067] The sub-guide tank 435 includes a first sub-guide chamber 442 and a second sub-guide chamber 443. A driving block 444 is slidably provided in the first sub-guide chamber 442, and a driving plug 445 is slidably provided in the second sub-guide chamber 443. Two return springs 446 are formed between the driving plug 445 and the inner wall of the first sub-guide chamber 442. The driving plug 445 is connected to an external driving unit to drive it to reciprocate along the second sub-guide chamber 443. The end of the second pipeline 440 away from the sewage storage interval is connected to the first sub-guide chamber 442. The first sub-guide chamber 442 is also provided with a fourth pipeline 447, and the fourth pipeline 447 is connected to the external sewage storage unit. The end of the third pipeline 441 away from the sieve chamber 436 is connected to the second sub-guide chamber 443. The second sub-guide chamber 443 is also provided with a fifth pipeline 448, and the other end of the fifth pipeline 448 is connected to the oil supply tank 431.

[0068] When in use, the oil supply tank 431 is located below the workpiece fixing seat 452 and is provided with a plurality of oil nozzles 432 on the front and rear sides. During the tooth opening process, the oil outlet 429 sprays cooling oil, and the oil cools down the gear shaping cutters 455 on both sides and the matching rack 201 workpieces at the same time, so as to avoid damage to the gear shaping cutters 455 or the matching rack 201 during processing; the sprayed oil falls from the oil outlet 429 to the oil return tank 433, is collected and reused, and the recovered oil carries metal debris generated by the tooth opening;

[0069] The oil supply tank 431 is connected to the oil supply system through a pipeline, and the driving plug 445 is connected to an external power mechanism (which belongs to the prior art and is not described here) to drive it to reciprocate along the second sub-guiding cavity 443. The driving plug 445 has two motion states and the two motion states are intermittently switched by the external power mechanism;

[0070] First (oil discharge state): the driving plug 445 reciprocates only in the second sub-guiding chamber 443. The movement of the driving plug 445 generates negative pressure. The negative pressure causes the oil in the return oil tank 433 to enter the filter tank 434 and is sent to the second sub-guiding chamber 443 through the second pipeline 440. The metal debris attached to the oil is blocked by the filter cover 438 and retained in the dirt storage area. The clean oil is returned to the oil supply tank 431 through the fifth pipeline 448.

[0071] Second (chip removal state): the driving plug 445 reciprocates at the intersection of the first sub-guide chamber 442 and the second sub-guide chamber 443. At this time, the driving plug 445 is blocked between the second pipeline 440 and the fifth pipeline 448. Therefore, the movement of the driving plug 445 will not cause the second sub-guide chamber 443 to generate negative pressure, and each reciprocating movement of the driving plug 445 will act on the driving block 444. The driving block 444 reciprocates along the first sub-guide chamber 442 due to the force of the return spring 446. In the above state, the first sub-guide chamber 442 generates negative pressure, and the negative pressure causes the oil in the return oil tank 433 to enter the dirt storage interval and enter the first sub-guide chamber 442 through the third pipeline 441. The oil brings the metal debris accumulated in the dirt storage interval into the first sub-guide chamber 442, and the above oil flushes the inner wall of the filter cover 438 to ensure its subsequent filtering effect. The oil entering the first sub-guide chamber 442 is transported to the external dirt storage unit by the fourth pipeline 447;

[0072] Among them, the first pipeline 439, the second pipeline 440, the third pipeline 441, the fourth pipeline 447 and the fifth pipeline 448 are all installed with check valves to prevent the backflow of clean oil and contaminated oil;

[0073] A threaded sleeve is installed on the bottom surface of the sieve cavity 436, and an adjusting screw is connected to the inner thread of the threaded sleeve. One end of the adjusting screw located in the sieve cavity 436 is connected to a positioning block. The positioning block is slidably arranged in the sieve cavity 436 and is rotatably connected to the screw. The position of the positioning block can be adjusted by rotating the adjusting screw forward or backward to control the flow of oil entering the sieve cavity 436.

[0074] In actual use, a cooling unit is built into the oil return tank 433 to cool the oil, so that the oil can maintain the cooling effect even if it is reused multiple times;

[0075] In summary, the oil supply system can realize the free switching between the oil discharge state and the chip removal state by controlling the driving plug 445 to flexibly switch between the two working states. In the oil discharge state, the metal impurities in the oil are automatically filtered, and in the oil discharge state, the impurities accumulated in the sieve cavity 436 are self-cleaned;

[0076] When the equipment is applied, the oil supply system of the tooth opening unit 401 is switched to the oil outlet state during the tooth opening process. At this time, clean oil is sprayed from the oil outlet nozzle 432 to cool the workpiece matching the rack 201 and the gear shaping cutter 455 to avoid deformation of the workpiece matching the rack 201 and the gear shaping cutter 45 due to overheating during the tooth opening process. When the tooth opening unit 401 is receiving and unloading materials, the oil supply system is switched to the chip discharge state to discharge the metal debris accumulated in the pollution storage interval, so that the filter cover 438 is always kept in a clean state to ensure its filtering effect.
