Detailed Implementation

[0026] The technical solution provided by the present invention will be further described below with reference to the accompanying drawings and specific implementation methods.

[0027] like Figures 1 to 7 As shown, a multi-channel optically stabilized backlash-eliminating gear device includes an equipment support 1 comprising a processing base 102. A processing bracket 101 is fixedly mounted on the top of the processing base 102. A first sliding support plate 113 and a second sliding support plate 114 are slidably mounted laterally at the front and rear ends of the processing bracket 101, respectively. An extension rod and a sliding groove are fixedly installed in the first sliding support plate 113 and the second sliding support plate 114, and they slide and cooperate with each other. A detection mechanism 2 and a cutting mechanism 3 are rotatably mounted in the first sliding support plate 113 at both ends, respectively. The detection mechanism 2 includes a first telescopic base 203. A light signal transmitter 202 is fixedly mounted on the top of the first telescopic base 203. A laser receiver 201 is fixedly mounted on the top of the first telescopic base 203 via a telescopic rod. The light signal transmitter 202 and the laser receiver 201 cooperate to detect the shape of the gear and the tilt angle of the gear teeth. The light signal is transmitted through the laser. The emitter 202 controls the focusing range of multiple laser beams and detects the position and number of received laser beams from the laser receiver 201 to detect the gear specifications. A first fixed ring 204 is fixedly installed on the first telescopic base 203. The inner ring of the first fixed ring 204 has gear patterns, and multiple rollers are rotatably installed on the outer ring of the first fixed ring 204. An annular groove is provided in the first sliding support plate 113, and the first fixed ring 204 rotates with the annular groove. A fourth motor 115 is fixedly installed in the first sliding support plate 113, and a gear is fixedly installed on the fourth motor 115. The gear on the fourth motor 115 meshes with the gear patterns on the inner ring of the first fixed ring 204. By controlling the rotation of the first motor 105, the first fixed ring 204 is driven to rotate in the first sliding support plate 113, adjusting the detection angle of the laser receiver 201 and the light signal emitter 202 to detect the tooth shape of the helical gear.

[0028] like Figures 1 to 7 As shown, the cutting mechanism 3 includes a second telescopic base 302. A cutting motor 301 is fixedly installed on the top of the second telescopic base 302. A cutting plate 304 is rotatably installed on the front end of the cutting motor 301. The cutting plate 304 is used to process the tooth groove of the gear. The bottom of the tooth groove is processed into a concave arc shape so that when the gear meshes with each other, there will be no gap on both sides of the tooth due to contact between the tooth and the bottom of the tooth groove, which would affect the accuracy of the gear transmission.

[0029] like Figures 1 to 7 As shown, a second fixing ring 303 is fixedly installed at the front end of the second telescopic base 302. The second fixing ring 303 has the same structure as the first fixing ring 204. The second fixing ring 303 is rotatably installed in the annular groove in the first sliding support plate 113.

[0030] like Figures 1 to 7As shown, a support base 4 is fixedly installed at the center of the processing base 102. The support base 4 includes a clamping base 401. Multiple clamping claws 402 are laterally slidably installed on the top of the clamping base 401. Supporting balls are hinged to the top of the clamping claws 402. The clamping claws 402 are used to support the gear and adjust the support position according to the structure of the two ends of the gear. A transmission rod 403 is hinged to the bottom of the clamping claws 402. An adjusting screw 404 is longitudinally rotatably installed on the bottom of the clamping base 401. An adjusting screw is fitted with an adjusting screw thread on the adjusting screw 404. The other end of the transmission rod 403 is hinged to the adjustment ring 405. A clamping bracket 103 is longitudinally slidably installed at the center of the processing bracket 101. A transmission clamping plate 108 is longitudinally rotatably installed inside the clamping bracket 103. The transmission clamping plate 108 is used to control the rotation of the gear. A gear is fixedly installed on the top of the transmission clamping plate 108. A second motor 106 is fixedly installed inside the clamping bracket 103. A gear is fixedly installed on the second motor 106. The gear on the second motor 106 meshes with the gear on the top of the transmission clamping plate 108.

[0031] like Figures 1 to 7 As shown, a pair of clamping threaded rods 104 are longitudinally rotatably mounted on the processing bracket 101. The clamping threaded rods 104 cooperate with the lead screw of the clamping bracket 103 to control the height of the equipment bracket 18 according to the thickness of the gear, so as to facilitate the clamping of the gear. A pulley is fixedly mounted on the top of the clamping threaded rods 104, and the clamping threaded rods 104 are connected by a belt. A first motor 105 is fixedly mounted on the top of the processing bracket 101, and a pulley is fixedly mounted on the first motor 105. The pulley on the top of the first motor 105 is connected to the clamping threaded rods 104 by a belt.

[0032] like Figures 1 to 7 As shown, a heating spray gun 109 and a cooling nozzle 110 are longitudinally slidably mounted on the left and right ends of the processing bracket 101, respectively. The heating spray gun 109 and the cooling nozzle 110 are used to heat and quench the processed gears to improve the wear resistance of the processed position. A pair of third motors 107 are fixedly mounted on the top of the processing bracket 101. A screw is fixedly mounted on the third motor 107. The screw on the third motor 107 is respectively engaged with the lead screw of the heating spray gun 109 and the cooling nozzle 110.

[0033] like Figures 1 to 7As shown, adjusting sliders 112 are rotatably mounted at both ends of the first sliding support plate 113 and the second sliding support plate 114. Four pairs of adjusting threaded rods 111 are rotatably mounted at the front and rear ends of the bottom of the processing base 102. Pulleys are fixedly mounted on the adjusting threaded rods 111, and each pair of adjusting threaded rods 111 is connected by a belt. The adjusting threaded rods 111 are used to control the sliding position of the first sliding support plate 113 and the second sliding support plate 114 within the processing base 102, facilitating the control of the position and tilt angle of the detection mechanism 2 and the cutting mechanism 3. The adjusting threaded rods 111 at the front and rear ends respectively cooperate with the adjusting sliders 112 on the left and right sides of the first sliding support plate 113 and the second sliding support plate 114. Two pairs of fifth motors 116 are fixedly installed at the bottom of the base 102. The fifth motors 116 are fixedly connected to the adjusting threaded rods 111. By starting the fifth motors 116, the adjusting threaded rods 111 are rotated, which causes the first sliding support plate 113 or the second sliding support plate 114 to slide within the processing base 102. When the sliding directions of the first sliding support plate 113 and the second sliding support plate 114 are different, the extension rod between the first sliding support plate 113 and the second sliding support plate 114 and the sliding groove are engaged, causing the first sliding support plate 113 and the second sliding support plate 114 to tilt within the processing base 102, and causing the detection mechanism 2 and the cutting mechanism 3 to tilt on the processing base 102, which facilitates the processing of the bevel gear.

[0034] Working principle: When backlash elimination is required on a gear, the gear to be processed is first placed on the surface of the clamping base 401. According to the size of the gear, the adjusting screw 404 is rotated to drive the adjusting ring 405 to slide, and the clamping claw 402 is driven to slide on the surface of the clamping base 401 through the transmission rod 403. The support position of the clamping claw 402 is adjusted. Then, the first motor 105 is started to drive the clamping threaded rod 104 to rotate and adjust the height of the clamping bracket 103. At this time, the transmission clamping plate 108 contacts the top of the gear, and the second motor 106 is started to drive the transmission clamping plate 108 to rotate, and the gear is driven to rotate through the transmission clamping plate 108.

[0035] Then, the fifth motor 116 is started to drive the adjusting threaded rod 111 to rotate, synchronously adjusting the processing and detection position and tilt angle of the detection mechanism 2 and the cutting mechanism 3. Then, the shape and angle of the gear teeth are detected by the laser receiver 201 and the light signal transmitter 202. The fourth motor 115 is started to drive the detection mechanism 2 and the cutting mechanism 3 to rotate synchronously, changing the processing angle. The cutting motor 301 is started to drive the cutting plate 304 to rotate, and the tooth groove is processed.

[0036] During the processing, the processed gear groove is heated by the heating spray gun 109 and quenched by the cooling spray head 110 to increase the wear resistance of the treated gear.
