Description

Technical Field

[0001] The invention relates to the technical field of gear processing, and in particular to a grinding device for gear production. Background Art

[0002] Gears are a common mechanical element that uses the principle of meshing transmission to transmit power to power. The ability of gears to complete power transmission and the accuracy of the transmission mainly depend on the distance between teeth on the gears. The main purpose of grinding gears during the production process is to obtain accurate tooth shape and improve the finish of the tooth surface.

[0003] The current grinding devices for gear production have been found to have at least the following technical problems:

[0004] First, when the current gear grinding device is processing and grinding the gear, it is necessary to first use a fixing fixture to fix the gear, and then operate the grinding equipment to grind it. This operation step is cumbersome, which affects the time for grinding the gear, thereby reducing the grinding efficiency.

[0005] Second, after the current gear grinding device processes a tooth surface of a gear, it is necessary to remove the butterfly grinding wheel, then disassemble the gear, and then replace the position of the gear tooth surface, which is very troublesome and increases the complexity of the operation.

[0006] Third, when the current gears are ground, there is no cleaning mechanism on the gear tooth surface. The debris generated when operating the previous surface may remain on the tooth surface. These debris will act as abrasives under the high-speed friction between the grinding wheel and the gear surface, causing additional scratches and wear, and affecting the smoothness and precision of the gear tooth surface.

Then, the sliding block 45 is pulled to move the two clamping plates 46 at its side ends to the right side of the device, and then the spur gear 51 is inserted from below the mounting hole 27 opened on the processing platform 11, and then pressure is applied to the two clamping plates 46 to make them move relatively toward the rotating rod 43, and the sliding block 45 is pushed in the opposite direction to allow the left end of the rotating rod 43 to be inserted into the inner ring of the spur gear 51, and the two clamping plates 46 are loosened. At this time, the second spring 47 Under the action of elastic force, the two clamping plates 46 will tightly clamp the spur gear 51, and then the locking screw 42 can be locked so that the upper end of the locking screw 42 is tightly fitted with the processing platform 11, thereby fixing the spur gear 51 and the sliding block 45. The present invention provides a fixing mechanism at the lower end of the processing platform 11 and a movable clamping plate 46 inside the processing platform 11, so that the device can be fixed when grinding spur gears 51 with different inner ring diameters, and the center point of its rotation will still be on the rotating rod 43, thereby effectively ensuring the accuracy of the device when grinding the spur gear 51, improving the applicability of the device, and effectively saving the cost of using the equipment.

[0034] A threaded rod 13 is rotatably installed in the limiting slide groove 12 opened on the processing platform 11, and the threaded rod 13 is rotatably installed on the side end of the convex shift plate 15 through a thread. A servo motor 14 is fixedly installed on the right end of the threaded rod 13 through an output shaft. Two support frames 17 are fixedly installed on the upper end of the convex shift plate 15, and two drive motors 19 are respectively fixedly installed on the separated ends of the two support frames 17. The two fixed rods 16 are both in contact with the tooth surface of the spur gear 51. A circular hole 35 is opened on the circumferential surface of the second T-shaped round rod 31. The limiting round rod 22 is slidably installed in the circular hole 35 opened in the second T-shaped round rod 31. After the spur gear 51 is fixed, the two drive motors 19 can be turned on, so that the two drive motors 19 drive the two disc-shaped grinding wheels 18 to rotate, and then the servo motor 14 is controlled to work by the PLC controller. The servo motor 14 drives the threaded rod 13 to rotate through the output shaft, and the threaded connection between the threaded rod 13 and the convex shift plate 15 is achieved. The convex shift plate 15 can move in the direction of the spur gear 51. At this time, the two fixing rods 16 at the front and rear ends of the convex shift plate 15 will first touch the tooth grooves of the spur gear 51 and fit with the tooth surface of the spur gear 51, thereby fixing the spur gear 51 and preventing it from rotating. Then, the two disc-shaped grinding wheels 18 will contact the two tooth surfaces of the spur gear 51 and grind the two tooth surfaces of the spur gear 51, thereby completing high-precision grinding processing. The present invention arranges two disc-shaped grinding wheels 18 on two support frames 17, and then arranges fixing rods 16 at the front and rear ends of the two convex shift plates 15, so that the position of the spur gear 51 can be fixed before the tooth surface of the spur gear 51 is ground, thereby preventing the spur gear 51 from rotating during grinding. Not only is the structure simple, but the operation is also quick. In addition, the convex shift plate 15 moves stably in the limiting slide groove 12 opened on the processing platform 11, thereby improving the grinding stability of the two disc-shaped grinding wheels 18 on the tooth surface of the spur gear 51.

[0035] The two side ends of the top rod 32 are fixedly installed with fixed sleeve rods 33, and the separated ends of the two fixed sleeve rods 33 are movably provided with wiping plates 34 through the rotating shaft. The two wiping plates 34 are both in contact with the tooth surface of the spur gear 51. A fixed plate 25 is fixedly installed on the processing platform 11. The left side of the fixed plate 25 is penetrated and slidably installed with a first T-shaped round rod 24. The first T-shaped round rod 24 is fixedly installed on the right side end of the U-shaped rod 21. The left circumferential surface of the first T-shaped round rod 24 is sleeved with a first spring 23. The first spring 23 is fixedly installed between the fixed plate 25 and the U-shaped rod 21. After the two tooth surfaces of the spur gear 51 are processed, the servo motor 14 is controlled to rotate in the opposite direction, so that the convex shift plate 15 can return to its original position. Then, when the fixing rod 16 at the front end of the convex shift plate 15 is about to contact the U-shaped rod 21, the two disc-shaped grinding wheels 18 and the fixing rod 16 on the convex shift plate 15 are separated from the spur gear 51. At this time, the fixing rod 16 continues to apply rightward pressure to the U-shaped rod 21 to make it move to the right. At this time, the left side of the U-shaped rod 21 will drive the limit round rod 22 and the second T-shaped round rod 31 to move. At this time, the second T-shaped round rod 31 is limitedly slidably installed in the special-shaped groove 26 opened on the processing platform 11, and the limiting round rod 22 and the second T-shaped round rod 31 are movable, so when the second T-shaped round rod 31 moves to the right in the special-shaped groove 26, the position will change, and the top rod 32 at the upper end of the second T-shaped round rod 31 has been in contact with the tooth surface of the spur gear 51 at this time. When the device moves, it will drive the spur gear 51 to rotate, thereby changing the position of the spur gear 51, so as to facilitate the grinding of the next tooth surface. The special-shaped groove 26 opened on the processing platform 11 and the second T-shaped round rod 31 movable in the special-shaped groove 26 enable the device to drive the U-shaped rod 21 to move while removing the two disc-shaped grinding wheels 18 from the spur gear 51, and then the position of the tooth surface of the spur gear 51 is replaced through the cooperation of the second T-shaped round rod 31 and the push rod 32. The position replacement of the spur gear 51 can be completed without performing multiple steps of manual operation, which reduces the time for replacing the position of the spur gear 51, thereby effectively improving the efficiency of the spur gear 51 during grinding.

[0036] A limit ring 44 is installed in the sliding block 45 for limiting rotation. The limit ring 44 penetrates and is fixedly installed on the circumferential surface of the rotating rod 43. A locking screw 42 is penetrated and installed on the sliding block 45 through a thread. The upper end of the locking screw 42 is fitted to the lower end of the processing platform 11. Two groups of third T-shaped rods 48 are slidably installed on the opposite surfaces of the clamping plate 46. The number of each group of third T-shaped rods 48 is two, and the two groups of third T-shaped rods 48 are respectively fixedly installed on both sides of the rotating rod 43. The circumferential surface of each third T-shaped rod 48 is sleeved with a second spring 47. The second spring 47 is fixedly installed between the rotating rod 43 and the clamping plate 46. In the present invention, when the second T-shaped round rod 31 and the push rod 32 move, the wiping plates 34 at the two side ends of the push rod 32 will also move, and fit and move with the two tooth surfaces that need to be polished under the spur gear 51, so as to wipe the tooth surfaces. A wiping cloth is provided on the side of the wiping plate 34 to wipe the tooth surface of the spur gear 51, and the debris generated when grinding the previous surface can be cleaned to avoid additional scratches and wear caused by these debris under the high-speed friction between the disc grinding wheel 18 and the tooth surface of the spur gear 51 when grinding the next surface, affecting the smoothness and accuracy of the gear tooth surface to ensure the grinding quality fit. The sliding block 45 in the present invention is set between the two mounting plates 41, so that the sliding block 45 can slide between the two mounting plates 41, and then the locking screw 42 is threadedly connected to fix the sliding block 45, which effectively improves the fixing effect of the sliding block 45 and improves the efficiency of the spur gear 51 when fixing. The installation of the spur gear 51 can be completed by moving the sliding block 45 back and forth, which is very convenient.

[0037] Working principle:

[0038] In the first step, when the device is precision grinding the tooth surface of the spur gear 51, the spur gear 51 is first fixed and installed, and the locking screw 42 and the sliding block 45 are loosened to make the sliding block 45 and the mounting plate 41 and the processing platform 11 active. Then, the sliding block 45 is pulled to move the two clamping plates 46 at its side ends to the right side of the device, and then the spur gear 51 is inserted from below the mounting hole 27 opened on the processing platform 11, and then pressure is applied to the two clamping plates 46 to make them move relatively toward the rotating rod 43, and the sliding block 45 is pushed in the opposite direction to allow the left end of the rotating rod 43 to be inserted into the inner ring of the spur gear 51, and the two clamping plates 46 are loosened. At this time, the second spring 4 Under the action of the elastic force of 7, the two clamping plates 46 will tightly clamp the spur gear 51, and then the locking screw 42 can be locked to make its upper end fit tightly with the processing platform 11, so as to fix the spur gear 51 and the sliding block 45. The present invention uses a fixing mechanism provided at the lower end of the processing platform 11 and a movable clamping plate 46 inside it, so that the device can be fixed when grinding spur gears 51 with different inner ring diameters, and the center point of its rotation will still be on the rotating rod 43, thereby effectively ensuring the accuracy of the device when grinding the spur gear 51, improving the applicability of the device, and effectively saving the cost of using the equipment.

[0039] In the second step, after the spur gear 51 is fixed, the two drive motors 19 can be turned on, so that the two drive motors 19 drive the two disc-shaped grinding wheels 18 to rotate, and then the servo motor 14 is controlled by the PLC controller to work. The servo motor 14 drives the threaded rod 13 to rotate through the output shaft. Through the threaded connection between the threaded rod 13 and the convex shift plate 15, the convex shift plate 15 can move toward the direction of the spur gear 51. At this time, the two fixing rods 16 at the front and rear ends of the convex shift plate 15 will first touch the tooth grooves of the spur gear 51 and fit with the tooth surface of the spur gear 51, thereby fixing the spur gear 51 so that it will not rotate. Then the two disc-shaped grinding wheels 18 will contact the spur gear 5 1, the two tooth surfaces of the spur gear 51 are ground, thereby completing high-precision grinding processing. The present invention arranges two disc-shaped grinding wheels 18 on two support frames 17, and then arranges fixing rods 16 at the front and rear ends of the two convex shifting plates 15, so that the position of the spur gear 51 can be fixed before the tooth surface of the spur gear 51 is ground, thereby preventing the spur gear 51 from rotating during grinding. Not only is the structure simple, but the operation is also quick, and there is no need to fix the spur gear 51 with complicated steps, thereby improving the grinding efficiency, and the convex shifting plate 15 moves stably in the limiting slide groove 12 opened on the processing platform 11, thereby improving the grinding stability of the two disc-shaped grinding wheels 18 on the tooth surface of the spur gear 51.

[0040] In the third step, after the two tooth surfaces of the spur gear 51 are processed, the servo motor 14 is controlled to rotate in the opposite direction, so that the convex shift plate 15 can be returned to its original position. Then, when the fixed rod 16 at the front end of the convex shift plate 15 is back to almost contact with the U-shaped rod 21, the two disc-shaped grinding wheels 18 and the fixed rod 16 on the convex shift plate 15 are separated from the spur gear 51. At this time, the fixed rod 16 continues to apply rightward pressure to the U-shaped rod 21 to move it to the right. At this time, the left side of the U-shaped rod 21 will drive the limiting round rod 22 and the second T-shaped round rod 31 to move. At this time, the second T-shaped round rod 31 is limitedly slidably installed in the special-shaped groove 26 opened on the processing platform 11, and the limiting round rod 22 and the second T-shaped round rod 31 are movable, so when the second T-shaped round rod 31 moves to the right in the special-shaped groove 26, a position change will occur. , and the push rod 32 at the upper end of the second T-shaped round rod 31 is now in contact with the tooth surface of the spur gear 51. When the device moves, it will drive the spur gear 51 to rotate, thereby changing the position of the spur gear 51, so as to facilitate the grinding of the next tooth surface. The present invention uses the special-shaped groove 26 opened on the processing platform 11 and the second T-shaped round rod 31 movable in the special-shaped groove 26, so that the device can drive the U-shaped rod 21 to move while removing the two disc-shaped grinding wheels 18 from the spur gear 51, and then the position of the tooth surface of the spur gear 51 is replaced through the cooperation of the second T-shaped round rod 31 and the push rod 32. The position replacement of the spur gear 51 can be completed without performing multiple steps of manual operation, which reduces the time for replacing the position of the spur gear 51, thereby effectively improving the efficiency of the spur gear 51 during grinding.

[0041] In the fourth step, while the second T-shaped round rod 31 and the push rod 32 move, the wiping plates 34 on both side ends of the push rod 32 will also move to fit and move with the two tooth surfaces of the spur gear 51 that need to be polished. A wiping cloth is provided on the side of the wiping plate 34 to wipe the tooth surface of the spur gear 51, so that the debris generated when the previous surface is polished can be cleaned up to avoid additional scratches and wear caused by these debris under the high-speed friction between the disc-shaped grinding wheel 18 and the tooth surface of the spur gear 51 when grinding the next surface, affecting the smoothness and accuracy of the gear tooth surface to ensure the grinding quality fit. The sliding block 45 in the present invention is set between the two mounting plates 41, so that the sliding block 45 can slide between the two mounting plates 41, and then it is threadedly connected through the locking screw 42, so that the sliding block 45 can be fixed, which effectively improves the fixing effect of the sliding block 45 and improves the efficiency of the spur gear 51 when it is fixed. The installation of the spur gear 51 can be completed by moving the sliding block 45 back and forth, which is very convenient.

[0042] Finally, it should be noted that: Obviously, the above embodiments are only examples for clearly explaining the present invention, and are not intended to limit the implementation methods. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived from this are still within the scope of protection of the present invention.
