Description

Technical Field

[0001] This invention relates to the field of gear technology, and in particular to a method for precision machining of gears. Background Technology

[0002] After gears are machined, they often have many burrs or sharp edges. These burrs not only affect transmission efficiency and increase transmission resistance, but can also easily scratch operators if not handled carefully. Therefore, gears generally require deburring finishing after rough machining. However, existing gear deburring finishing processes have the following problems:

[0003] 1. Traditional gear deburring methods usually involve manually operating a grinding wheel or file in conjunction with a mechanism that drives the gear to rotate, and manually cleaning the gear. This deburring cleaning method is inefficient and labor-intensive. Furthermore, since each processing operation requires workers to install and disassemble the gear, the labor intensity is further increased, raising labor costs.

[0004] 2. Traditional gear deburring is usually done by grinding wheels or files, which makes it impossible to effectively clean the various tooth surfaces of the gear during deburring, resulting in incomplete deburring and reduced processing efficiency. Summary of the Invention

[0005] The purpose of this invention is to provide a gear finishing method that is not only simple to operate but also efficient in machining end face gears.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a gear finishing method, comprising the following steps:

[0007] S1. Place the gear to be processed into the feed trough of the feeding assembly with the back plate facing right. The feeding assembly is mounted on the frame. The gear in the feed trough enters the gear slot through the feed port.

[0008] S2. Start the moving component set on the frame to push the gear in the gear slot to the processing position, at which time the next gear in the material trough enters the gear slot;

[0009] S3. Control the grinding assembly mounted on the frame to process the gear in the processing position;

[0010] S4. After the gear is processed, the moving component releases the gear from its positioning. The gear moves downward under the action of gravity and is guided by the unloading component to be fed onto the conveyor belt located on the side of the frame.

[0011] S5. Repeat S3 to S4 to automatically deburr the gears.

[0012] Furthermore, the feeding assembly includes a hopper, which is fixedly installed between the left and right side plates of the frame. The hopper has a material trough inside. A guide rod is slidably connected to the left end of the hopper in the left-right direction. A feeding plate that is slidably connected to the right end of the guide rod in the left-right direction is fixedly provided in the material trough. A first spring is sleeved on the guide rod in the material trough. The first spring is used to force the feeding plate to move to the right. A radially extending convex plate is provided at the right end of the hopper. A gear groove is provided in the radially extending convex plate. A feed inlet for connecting the material trough and the gear groove is provided at the right end of the hopper.

[0013] Furthermore, the moving assembly includes a moving shaft. The lower end of the hopper is provided with a downwardly extending left support and a right support. The moving shaft is movably connected between the left and right supports in a left-right direction. The moving shaft is coaxial with a gear located in a gear slot.

The moving shaft has a limiting protrusion on its outer side near the right end. The left end of the moving shaft is located to the left of the left support and has a left stop. A second spring is sleeved on the moving shaft, located between the left support and the left stop. The second spring forces the moving shaft to move to the left. When the moving shaft is in the left-end position, the limiting protrusion of the moving shaft abuts against the right end of the first through hole. When in the right-end position, the right end of the moving shaft extends into the shaft hole of the gear, and the limiting protrusion abuts against the left end of the shaft hole of the gear, pushing the right side of the gear against the right side plate of the frame, thus pushing the gear to the processing position; the moving shaft has a first groove on the right side of the limiting protrusion, and a first positioning block and a third spring for forcing the upper end of the first positioning block to extend out of the first groove are provided in the first groove; the upper right side of the first positioning block has a first inclined surface; when the right end of the moving shaft is inserted into the shaft hole of the gear, the first positioning block compresses the third spring and retracts into the first groove; when the gear rotates and the limiting groove of the shaft hole is aligned with the first positioning block, the first positioning block extends into the limiting groove, and at this time the gear rotates, driving the moving shaft to rotate.

[0014] Furthermore, the left bracket is provided with a second through hole for the movable shaft to extend into, and the inner wall of the second through hole is provided with a first limiting groove. The outer side of the movable shaft is provided with a first limiting protrusion along the axial direction of the movable shaft for sliding connection within the first limiting groove. When the first limiting protrusion is within the first limiting groove, the movable shaft can only slide in the left and right directions. When the movable shaft is in the right end position, the left end of the first limiting protrusion moves to the right away from the first limiting groove. A positioning component is provided in the left bracket of the movable shaft, and the positioning component is used to position the movable shaft in the right end position.

[0015] Furthermore, the positioning component includes a second positioning block. The left bracket has a second slot communicating with the second through hole. The second positioning block is located within the second slot. A fourth spring is provided within the second slot to force the second positioning block against the outside of the moving shaft. A positioning ring groove is provided on the outside of the moving shaft for the upper end of the second positioning block to extend into. When the moving shaft is in the right-end position, the upper end of the second positioning block extends into the positioning ring groove. The left bracket has a third slot communicating with the second slot. A first positioning ball is provided within the third slot. The second positioning block has a first ball groove for the first positioning ball to extend into. When the first positioning ball enters the first ball groove, the second positioning block moves away from the second through hole and retracts into the second slot. When the first positioning ball moves away from the first ball groove and retracts into the third slot, the fourth spring forces the second positioning block to extend upwards into the third slot. The first positioning ball has a left protruding rod extending to the left of the left support at its left end and a right protruding rod extending to the right of the left support at its right end; a radial rod located to the right of the right protruding rod is provided on the outer side of the moving shaft; a first protrusion extending to the right is provided on the left side, and a second inclined surface cooperating with the left protruding rod is provided at the right end of the first protrusion; when the moving shaft is in the right end position and the moving shaft drives the first rotation, the second inclined surface of the first protrusion cooperates with the left protruding rod to push the first positioning ball away from the first ball groove and retract into the third groove; when the moving shaft is in the left end position, the radial rod abuts against the right protruding rod to drive the first positioning ball away from the first ball groove and retract into the third groove; a second positioning ball is provided in the left support, and a positioning spring is provided to force the second positioning ball to press against the first positioning ball; the second positioning ball is used to position the first positioning ball in the third groove or the first ball groove.

[0016] Furthermore, the grinding assembly includes a shaft rotatably connected between the left and right side plates of the frame. The outer side of the shaft is provided with a first spiral blade and a second spiral blade. When the shaft rotates, the second spiral blade contacts the left stop and pushes the left stop, causing the moving shaft to move to the right. When the second spiral blade disengages from the left stop, the moving shaft is in the right-end position. The right end of the shaft is provided with a right stop, which has a first notch. When the moving shaft moves to the right, the gear in the gear slot faces the first notch. When the gear is in the processing position, the gear is limited between the right stop and the right side plate of the frame. The right end face of the right stop is provided with two concentric arc-shaped rigid brush rings, which are used to clean burrs between the gear teeth.

[0017] Furthermore, a first gear coaxial with the shaft is fixedly provided on the right side plate of the frame, and a second gear meshing with the first gear is rotatably connected at the eccentric position of the right side. A steel brush ball is fixedly provided on the right end face of the second gear. The steel brush ball is used to clean the burrs on the surface of the gear, and at the same time, it drives the gear to rotate when the right side rotates.

[0018] Furthermore, a first motor for driving the shaft rotation is fixedly installed on the left side plate of the frame.

[0019] Furthermore, the feeding assembly includes a feeding guide plate provided on the right side plate of the frame, and the feeding guide plate is provided with a blocking edge.

[0038] Please see Figure 1-13 As shown, a gear finishing method includes the following steps:

[0039] S1. Place the gear 4 to be processed into the feed trough 216 of the feeding assembly with the back plate facing right. The feeding assembly is set on the frame 1. The gear 4 in the feed trough 216 enters the gear groove 212 through the feed port.

[0040] S2. Start the moving component set on the frame 1 to push the gear 4 in the gear slot 212 to the processing position. At this time, the next gear 4 in the material slot 216 enters the gear slot 212.

[0041] S3. Control the grinding assembly set on the frame 1 to process the gear 4 in the processing position;

[0042] S4. After the gear 4 is processed, the moving component releases the positioning of the gear 4, and the gear 4 moves downward under the action of gravity and is guided by the unloading component to be fed into the conveyor belt located on the side of the frame 1.

[0043] S5. Repeat S3 to S4 to automatically deburr gear 4.

[0044] The feeding assembly includes a hopper 21a, which is fixedly installed between the left and right side plates of the frame 1. The hopper 21a contains a material trough 216. A guide rod 22a is slidably connected to the left end of the hopper 21a in a left-right direction. A feeding plate 22, which is slidably connected to the right end of the guide rod 22a in the material trough 216, is fixedly installed in the right end of the guide rod 22a. A first spring 23 is sleeved on the guide rod 22a in the material trough 216, and the first spring 23 forces the feeding plate 22 to move to the right. A radially extending convex plate 21b is provided at the right end of the hopper 21a, and a gear groove 212 is provided within the radially extending convex plate 21b. An inlet 218 is provided at the right end of the hopper 21a to connect the material trough 216 and the gear groove 212. The unloading assembly includes a unloading guide plate 111 provided on the right side plate of the frame 1, and a blocking edge 112 is provided on the unloading guide plate 111.

[0045] The moving assembly includes a moving shaft 24. The lower end of the hopper 21a has a downwardly extending left support 21c and a right support 211. The moving shaft 24 is movably connected between the left support 21c and the right support 211 in a left-right direction. The moving shaft 24 is coaxial with the gear 4 located in the gear groove 212. The radial protrusion 21b has a first through hole 21d for the right end of the moving shaft 24 to extend to the right. The moving shaft 24 has a limiting protrusion 244 on its outer side near the right end. The left end of the moving shaft 24 is located to the left of the left support 21c and has a left stop 241. A second spring 25 is sleeved on the moving shaft 24, located between the left support 21c and the left stop 241. The second spring 25 forces the moving shaft 24 to move to the left. When the moving shaft 24 is in the left position, the limiting protrusion 244 abuts against the right end of the first through hole 21d. When gear 4 is in the right position, the right end of the moving shaft 24 extends into the shaft hole of gear 4, and the limiting protrusion 244 abuts against the left end of the shaft hole of gear 4, pushing the right side of gear 4 against the right side plate of the frame 1, thus pushing gear 4 to the processing position; the moving shaft 24 has a first slot 245 on the right side of the limiting protrusion 244, and a first positioning block 261 and a third spring 262 for forcing the upper end of the first positioning block 261 to extend out of the first slot 245 are provided in the first slot 245; the upper right side of the first positioning block 261 has a first inclined surface 2611; when the right end of the moving shaft 24 is inserted into the shaft hole of gear 4, the first positioning block 261 compresses the third spring 262 and retracts into the first slot 245; when gear 4 rotates and the limiting slot 41 of the shaft hole is aligned with the first positioning block 261, the first positioning block 261 extends into the limiting slot 41, and at this time, the rotation of gear 4 drives the moving shaft 24 to rotate. The left bracket 21c is provided with a second through hole 21e for the movable shaft 24 to extend into. The inner sidewall of the second through hole 21e is provided with a first limiting groove 217. The outer side of the movable shaft 24 is provided with a first limiting protrusion 242 along the axial direction of the movable shaft 24 for sliding connection within the first limiting groove 217. When the first limiting protrusion 242 is within the first limiting groove 217, the movable shaft 24 can only slide in the left and right directions. When the movable shaft 24 is in the right end position, the left end of the first limiting protrusion 242 moves to the right away from the first limiting groove 217. A positioning component is provided in the left bracket 21c of the movable shaft 24, which is used to position the movable shaft 24 in the right end position.

[0046] The positioning assembly includes a second positioning block 271. The left bracket 21c has a second slot 214 communicating with the second through hole 21e. The second positioning block 271 is located within the second slot 214. The second slot 214 contains a fourth spring 272 for forcing the second positioning block 271 against the outside of the moving shaft 24. The outside of the moving shaft 24 has a positioning ring groove 247 into which the upper end of the second positioning block 271 extends. When the moving shaft 24 is in the right-hand position, the upper end of the second positioning block 271 extends into the positioning ring groove 247. The left bracket 21c... 1c is provided with a third slot 21f that communicates with the second slot 214. The third slot 21f is provided with a first positioning ball 281. The second positioning block 271 is provided with a first ball groove 2711 for the first positioning ball 281 to extend into. When the first positioning ball 281 enters the first ball groove 2711, the second positioning block 271 leaves the second through hole 21e and retracts into the second slot 214. When the first positioning ball 281 leaves the first ball groove 2711 and retracts into the third slot 21f, the fourth spring 272 forces the second positioning block 271 to extend upward into the positioning ring groove 247. The first positioning ball 281 has a left protruding rod 282 extending to the left of the left bracket 21c at its left end and a right protruding rod 283 extending to the right of the left bracket 21c at its right end; the outer side of the moving shaft 24 has a radial rod 243 located to the right of the right protruding rod 283; the left stop 241 has a first protrusion 246a extending to the right, and the right end of the first protrusion 246a has a second inclined surface 246 that cooperates with the left protruding rod 282; when the moving shaft 24 is in the right end position and the moving shaft 24 drives the first rotation, the second inclined surface 246 of the first protrusion 246a and the left protruding rod 282 cooperates to push the first positioning ball 281 away from the first ball groove 2711 and retract into the third groove 21f. When the moving shaft 24 is in the left end position, the radial rod 243 abuts against the right protruding rod 283, causing the first positioning ball 281 to leave the first ball groove 2711 and retract into the third groove 21f. The left bracket 21c is provided with a second positioning ball 291 and a positioning spring 292 for forcing the second positioning ball 291 to press against the first positioning ball 281. The second positioning ball 291 is used to position the first positioning ball 281 in the third groove 21f or the first ball groove 2711.

[0047] The grinding assembly includes a shaft 32 rotatably connected between the left and right side plates of the frame 1. The outer side of the shaft 32 is provided with a first spiral blade 321 and a second spiral blade 322. When the shaft 32 rotates, the second spiral blade 322 contacts the left stop 241 and pushes the left stop 241, causing the moving shaft 24 to move to the right. When the second spiral blade 322 disengages from the left stop 241, the moving shaft 24 is in the right-end position. The right end of the shaft 32 is provided with a right stop 37, which has a first notch 372. When the moving shaft 24 moves to the right, the gear 4 in the gear groove 212 faces the first notch 372. When the gear 4 is in the processing position, the gear 4 is limited between the right stop 37 and the right side plate of the frame 1. The right end face of the right stop 37 is provided with two concentric arc-shaped rigid brush rings 36, which are used to clean the burrs between the teeth of the gear 4. A first gear 33, coaxial with the shaft 32, is fixedly mounted on the right side plate of the frame 1. A second gear 34, meshing with the first gear 33, is rotatably connected at the eccentric position of the right side flange 37. A steel brush ball 35 is fixedly mounted on the right end face of the second gear 34. The steel brush ball 35 is used to clean burrs on the surface of the gear 4 and simultaneously drives the gear 4 to rotate when the right side flange 37 rotates. A first motor 31 for driving the shaft 32 to rotate is fixedly mounted on the left side plate of the frame 1.

[0048] In the above S1 of this embodiment, as follows Figure 1 The image shown is a three-dimensional view of the present invention. Figure 2 This is a schematic diagram illustrating the positional relationship of the present invention. The present invention is equipped with three identical sets of feeding components. For example... Figure 3 The diagram shows the initial state of the invention, with the moving rod positioned on the far left under the action of the second spring 25. The radial rod 243 on the moving rod is in contact with the right convex rod 283, and the first positioning ball 281 is located within the third slot 21f on the far left. A second positioning block 271 and a fourth spring 272 are installed within the second slot 214; the second positioning block 271 is in contact with the moving rod under the action of the fourth spring 272. The feeding plate 22 is located on the far right of the material trough 216. The first notch 372 of the right retaining edge 37 is offset from the gear grooves 212 of the three sets of feeding assemblies. When deburring and finishing of the gear 4 is required, [the following is a continuation of the previous sentence, which is missing from the original text]. Figure 4Pull the guide rod 22a on the left, and then place the gear 4 to be processed into the material groove 216 with the back plate facing right. After the gear 4 is placed into the material groove 216, release the guide rod 22a. Under the action of the first spring 23, the loading plate 22 moves to the right, pushing the gear 4 in the material groove 216 to the left. The rightmost gear 4 moves to the right under the action of the loading plate 22 and arrives at the feed inlet 218, entering the gear groove 212 through the feed inlet 218. After the gear 4 enters the gear groove 212, the left end face 213 of the gear groove 212 engages with the right stop 37, limiting the gear 4 entering the gear groove 212. After the rightmost gear 4 moves downward into the gear groove 212, the next gear 4 in the feed trough 216 moves to the right again under the action of the feed plate 22 and moves downward through the feed inlet 218. However, because there is a gear 4 in the lower gear groove 212, the gear 4 in the upper feed inlet 218 cannot fall down and blocks the feed inlet 218. When the feed inlet 218 is blocked, the gear 4 in the upper feed trough 216 can no longer move to the right. After completing the above steps, the preparation work of the present invention is completed.

[0049] In S2 of this embodiment, when the control moving component pushes the gear 4 in the gear slot 212 to the processing position, the first motor 31 is started, and the first motor 31 rotates counterclockwise. Figure 3 This causes the shaft 32 to rotate counterclockwise. The shaft 32 has a first spiral blade 321 and a second spiral blade 322 mounted front and rear. When the shaft 32 rotates counterclockwise, the first spiral blade 321 and the second spiral blade 322 rotate together. After rotating counterclockwise by a certain angle, the second spiral blade 322 contacts the left stop 241. As the second spiral blade 322 continues to rotate, it pushes the left stop 241 to overcome the resistance of the second spring 25, moving towards... Figure 3 The movement to the right pushes the moving rod to the right as well. When the second spiral blade 322 pushes the moving rod to the right, the right stop 37 rotates until the first notch 372 is directly opposite the moving rod of the feeding assembly. After the moving rod moves a certain distance to the right, the rightmost end of the moving rod enters the shaft hole of the gear 4. As the moving rod continues to move to the right, it pushes the gear 4 to move to the right through the limiting protrusion 244, passing over the first notch 372 and sticking to the right side plate of the frame 1. When the gear 4 moves to the right with the moving rod and sticks to the right side plate of the frame 1, it reaches the processing position. After the above steps are completed, the gear 4 is limited by the combined action of the limiting protrusion 244 and the right side plate of the frame 1. When the lower gear 4 is pushed to the processing position, the gear 4 in the upper feed port 218 is no longer blocked by the lower gear 4, falls down a certain distance and lands on the moving rod, continuing to block the feed port 218. The gear 4 in the upper feed trough 216 still cannot move to the right (as if...). Figure 4(As shown). On the other side, after the moving rod is pushed to the far right by the second spiral plate 322, the positioning ring groove 247 comes above the second positioning block 271. The second positioning block 271 rises under the action of the fourth spring 272 and cooperates with the positioning ring groove 247 to position the moving rod, preventing it from returning to its original position under the action of the second spring 25. After completing the above steps, the invention completes the loading process.

[0050] In S3 of this embodiment, when the grinding assembly mounted on the frame 1 processes the gear 4 in the processing position, as the first motor 31 continues to rotate, the right stop 37 rotates together with the shaft 32. This causes the two sets of concentric arc-shaped steel brush rings of different diameters on the right stop 37 to rotate together, cleaning the burrs between the teeth of the gear 4 (e.g., ...). Figure 6 (As shown). As the first motor 31 continues to rotate, the right stop 37 continues to rotate. When the arc-shaped steel brush ring rotates away from the gear 4, the steel brush ball 35 on the right stop 37 rotates and enters between two teeth below the gear 4. The first gear 33 is fixedly mounted on the right side plate of the frame 1 via the gear shaft 331, and the second gear 34 is rotatably mounted on the shaft 371. At the same time, the first gear 33 and the second gear 34 mesh, so when the right stop 37 rotates and the shaft 371 rotates around the shaft 32 along with the mounting plate, the second gear 34 will also rotate around the shaft 371 while rotating around the shaft 32. When the steel brush ball 35 enters between two teeth below the gear 4, the steel brush ball 35 rotates together with the second gear 34, further cleaning the tooth surfaces of the two teeth. At the same time, as the steel brush ball 35 rotates around the shaft 32, the contact between the steel brush ball 35 and the tooth surface while cleaning causes the gear 4 to rotate around the moving shaft 24. As the steel brush ball 35 rotates around the shaft 32, enters the tooth surface for cleaning, and then leaves, the gear 4 rotates exactly one tooth angle (e.g., ...). Figure 7 , Figure 8 As shown, with each tooth of gear 4 rotated, the steel brush ball 35 can clean the next tooth surface of gear 4 when it reaches its next rotation position. When the first motor 31 drives the right stop 37 to rotate continuously, the arc-shaped steel brush ring and the steel brush ball 35 clean the tooth surface of gear 4 while also driving gear 4 to rotate, enabling the present invention to clean all tooth surfaces of gear 4 in an all-round way.

[0051] At the same time, while the arc-shaped steel brush ring and steel brush ball 35 are cleaning, the first spiral blade 321 and the second spiral blade 322 at the rear also rotate with the shaft 32 to fan the air and dissipate heat to the processing area in front, ensuring that the present invention will not generate high temperatures during batch processing.

[0052] As the steel brush ball 35 continuously pushes the gear 4 to rotate, when the gear 4 rotates to a certain angle, the limiting groove 41 on the gear 4 engages with the first positioning block 261. The first positioning block 261, under the action of the third spring 262, rises and enters the limiting groove 41. After the first positioning block 261 enters the limiting groove 41, during subsequent cleaning, as the steel brush ball 35 pushes the gear 4 to rotate, the gear 4 also drives the moving rod to rotate along with it via the first positioning block 261. When the moving rod rotates with the gear 4, the first limiting protrusion 242 on the moving rod also rotates away from the first limiting groove 217. As the first motor 31 continues to rotate, the steel brush ball 35 continuously cleans and pushes the gear 4 to rotate, and the gear 4 also drives the moving rod to rotate along with it. When the moving rod rotates to a certain angle, the second inclined surface 246 on the first protrusion 246a on the moving rod contacts the left protrusion 282. As the moving rod rotates again, the second inclined surface 246 pushes the left protrusion 282 towards... Figure 11 The movement proceeds to the right. The left protruding rod 282 drives the first positioning ball 281 and the right protruding rod 283 to move to the right together. After moving to the right, the first positioning ball 281 enters the first ball groove 2711. Once inside the first ball groove 2711, the second positioning ball 291 moves downwards under the push of the positioning spring 292, limiting the movement of the first positioning ball 281. Meanwhile, the first positioning ball 281 enters the first ball groove 2711, pushing the second positioning block 271 to overcome the resistance of the fourth spring 272 and retract downwards, thus releasing the limitation on the moving rod. At this point, although the second positioning block 271 has released the limitation on the moving rod, the moving rod is still limited by the action of the first limiting protrusion 242.

[0053] In the above S4 of this embodiment, when the control moving component releases the positioning of the gear 4, as the steel brush ball 35 cleans and drives the gear 4 to rotate, the gear 4 in turn drives the moving shaft 24 to rotate. After the moving shaft 24 rotates one revolution, the gear 4 completes the cleaning. As the moving shaft 24 rotates one revolution, the gear 4 completes the cleaning, and the first limiting protrusion 242 rotates back to the first limiting groove 217. At this time, since there is no second positioning block 271 limiting it, the moving shaft 24 moves under the action of the second spring 25. Figure 4The left side retracts to its initial position. When the moving shaft 24 returns to its initial position, the limiting protrusion 244 engages with the reset plate 219, preventing the moving shaft 24 from moving further to the left, thus completing the limiting of the moving shaft 24. At this time, the moving shaft 24 is in the left end position. During the process of the moving shaft 24 returning to the left end position, the radial rod 243 pushes the right protrusion 283 to move to the left together. The right protrusion 283 moving to the left causes the first positioning ball 281 and the left protrusion 282 to move to the left together. When the first positioning ball 281 pushes open the positioning of the second positioning ball 291 and leaves the first ball groove 2711, the second positioning block 271 is unlocked. The second positioning block 271 rises again under the action of the fourth spring 272 and engages with the moving rod. As the second positioning block 271 moves upward, the right protrusion 283 moves downward relative to the right in the groove 2713.

[0054] On the other side, after the moving shaft 24 returns to its initial position, the gear 4 loses its positioning and moves downward under the action of gravity. The gear 4 falls into the feeding guide plate 111 and, under the action of the inclined feeding guide plate 111 and the blocking edge 112, moves into the conveyor belt to complete the collection.

[0055] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
