Description

Technical Field

[0001] This utility model relates to the field of gear processing technology, and in particular to a burr removal device for gear processing. Background Technology

[0002] Gears are key components in mechanical transmission, and their machining quality directly affects the performance and lifespan of mechanical products. During the cutting, grinding and other machining processes of gears, burrs are easily generated on the tooth surface, tooth root and inner hole edge. These burrs not only affect the assembly accuracy of the gears, but also lead to increased friction, increased noise and even premature gear failure during use. Therefore, it is necessary to clean the burrs.

[0003] Application No. 202421770850.5 relates to a surface burr removal device for gear processing. This utility model mainly consists of a loading component, a feeding component, and a cleaning component. The feeding component releases the gear workpieces to be processed one by one into the groove of the feeding station, so that the shaft hole of the gear workpiece is sleeved on the outside of the flipping shaft. Then the loading component moves to transfer the gear workpiece to the cleaning station. The stamping push rod in the cleaning component moves to drive the grinding gear mounting plate and grinding gear to move up and down reciprocally, removing burrs from part of the tooth groove surface of the gear workpiece. After each cleaning is completed, the flipping motor drives the gear workpiece to rotate a certain angle, and the next cleaning operation can be performed until the burrs on the tooth groove surface of the entire gear workpiece are removed. During the cleaning process, the gear workpiece is attracted and locked by an electromagnet bearing seat. After the cleaning is completed, the attraction is released, and the gear workpiece is quickly removed with the help of a robot arm.

[0004] The above solution has shortcomings in use. When the cleaning mechanism is working, it can only descend from directly above the gear to clean part of the tooth groove surface. However, the edge of the tooth groove surface at the bottom of the gear that contacts the electromagnet pressure seat cannot be effectively cleaned. As a result, the workers have to turn the gear over and clean the burrs again, which seriously affects the cleaning efficiency of gear burrs. Therefore, we provide a burr cleaning device for gear processing. Utility Model Content

[0033] Second Embodiment

[0034] As attached Figure 1 Appendix Figure 4 Appendix Figure 5 With appendix Figure 6As shown: Cleaning component 3, mounted on support plate 1, includes a set of U-shaped plates 301 slidably connected to support plate 1, a set of symmetrical annular grinding teeth 302 mounted on the set of U-shaped plates 301, and a drive structure mounted on support plate 1 for reciprocating lifting of the set of annular grinding teeth 302. The drive structure includes a frame 303 mounted on the upper surface of support plate 1. A double-headed motor 304 is mounted on the bottom surface of the top of the frame 303. Both output ends of the double-headed motor 304 are fixedly connected to rotating rods 305. The other end of each rotating rod 305 is fixedly connected to a turntable 306. A top pull plate 307 is rotatably connected to the edge of one side of each turntable 306. One side of the bottom end of each top pull plate 307 is rotatably connected to... There is a connecting shaft 308, and the other end of each connecting shaft 308 is connected to the upper surface of the U-shaped plate 301. When the dual-head motor 304 is working, it will drive the rotating rod 305 to rotate synchronously. The turntable 306 will drive the top pull plate 307 to rotate around the center of the rotating rod 305. When the top pull plate 307 rotates, its bottom end will drive the U-shaped plate 301 to reciprocate up and down. When the U-shaped plate 301 descends, the top annular grinding teeth 302 will descend to grind and deburr the gear tooth groove surface. As the bottom annular grinding teeth 302 rises, they can enter the tooth groove from the bottom of the gear, thereby achieving the effect of grinding and deburring the edge of the bottom tooth groove surface. It can achieve full tooth surface burr cleaning without secondary flipping, further ensuring the cleaning efficiency of burrs.

[0035] Each rotating rod 305 has a reinforcing plate 309 rotatably connected to its outer surface. The top of each reinforcing plate 309 is connected to the bottom surface of the top of the frame 303. The reinforcing plate 309 can reinforce and stabilize the rotating rod 305, further enhancing the stability of the turntable 306 during rotation. Each U-shaped plate 301 has a set of stabilizing plates 310 slidably connected to it. The ends of each set of stabilizing plates 310 that are close to each other are connected to the upper surface and the bottom surface of the support plate 1, respectively. The stabilizing plates 310 can guide and stabilize the U-shaped plate 301 to prevent the annular grinding teeth 302 from shifting due to uneven force, thereby preventing the annular grinding teeth 302 from meshing misalignment or excessive clearance between the gear tooth groove surface and the gear.

[0036] The gear holding mechanism includes a set of hanging plates 311 fixedly connected to the upper surface of the frame 303. The bottom ends of the set of hanging plates 311 are all fixedly connected to an electric push rod 312. The telescopic end of the electric push rod 312 is equipped with a pressure cylinder 313. When the gear is placed inside the sleeve 201, the electric push rod 312 is extended and the pressure cylinder 313 will descend to hold the gear firmly, so as to prevent the gear from moving up and down due to force when the ring grinding gear 302 is raised and lowered, thereby ensuring the effect of grinding and deburring the gear. A flexible pad 314 is fixedly connected to the bottom surface of the pressure cylinder 313. The flexible pad 314 can protect the top surface of the gear to prevent damage to the gear.

[0037] Working principle: When in use, the gear is placed inside the sleeve 201 and fitted onto the outside of the positioning pin 204. At this time, the tooth groove surface of the gear will be aligned with the annular grinding tooth 302. Then, the electric push rod 312 is extended, and the pressure cylinder 313 descends to hold the gear stably. Next, the dual-head motor 304 is started, and the rotating rod 305 will rotate synchronously. The turntable 306 will drive the top pull plate 307 to rotate around the center of the rotating rod 305. When the top pull plate 307 rotates, its bottom end will drive the U-shaped plate 301 to reciprocate up and down. When the U-shaped plate 301 descends, the annular grinding tooth 302 at the top will descend to grind and deburr the tooth groove surface of the gear. As the annular grinding tooth 302 at the bottom rises, it can enter the tooth groove from the bottom of the gear, thereby achieving the effect of grinding and deburring the edge of the bottom tooth groove surface. It can achieve full tooth surface burr cleaning without secondary flipping, further ensuring the cleaning efficiency of burrs.
