Description

Technical Field

[0001] The present invention relates to the technical field of workpiece grinding, and particularly to an automatic grinding device for flywheel castings. Background Art

[0002] A flywheel is a disc-shaped part with a large moment of inertia, and its function is like an energy storage device. For a four-stroke engine, work is done once every four piston strokes, that is, only the power stroke does work, while the exhaust, intake, and compression strokes all consume work. Therefore, the torque output by the crankshaft changes periodically, and the crankshaft speed is also unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft, usually made by metal casting, and its rough workpiece still needs to be polished and finely processed;

[0003] According to a Chinese patent with the application publication number 202110694358.9, a grinding device for flywheel castings is disclosed. By installing a grinding mechanism for grinding the flywheel body on the outer side wall of the rotating cylinder, it is convenient to grind the flywheel body and improve the grinding speed. The setting of the slideway realizes the rotation of the first rotating plate by the sliding block driven by the fixed cylinder, so as to realize the positioning and release of the grinding mechanism driving the telescopic plate for the flywheel body, thereby improving the stability of the flywheel body during grinding. After using the above automatic grinding device for flywheel castings, it is found that the device cannot grind the edges and corners of the flywheel smoothly, resulting in burrs at the edges and corners of the flywheel after grinding, so further processing is required, which makes the grinding steps of the flywheel complex and not simple enough. Therefore, we propose an automatic grinding device for flywheel castings to solve the above technical problems. Summary of the Invention

[0068] Compared with the prior art, the beneficial effects of the present invention are:

[0069] 1. In the present invention, the Y-axis moving unit of the grinding mechanism drives the loading plate to reciprocate up and down. Further, the swing plate drives the grinding sheet to reciprocate up and down. At the same time, the reciprocating movement of the swing plate up and down also drives the block to move together, making the block continuously contact the outer walls of the upper and lower limit pins. As a result, the swing plate drives the shaft pin to reciprocate forward and backward along the inner wall of the loading plate by a certain angle, causing the elastic piece to undergo elastic deformation. Moreover, the reciprocating movement of the swing plate forward and backward also drives the grinding sheet to twist together, realizing chamfer grinding of the corners of the flywheel casting and ensuring that the corners of the flywheel casting are round and smooth.

[0070] 2. In the present invention, by rotating the handwheel to drive the forward and reverse screw rod to rotate, the distance between the upper and lower adjusting seats can be adjusted, thereby driving the limit pins to be adjusted together. At the same time, the distance that the Y-axis moving unit drives the loading plate to reciprocate up and down needs to be adjusted correspondingly to the distance between the two limit pins, which is convenient for grinding and processing flywheel castings of different thicknesses.

[0071] 3. In the present invention, the flywheel casting is conveyed by the feeding conveying roller, and then the flywheel casting conveyed to the end of the feeding conveying roller is pushed to the top of the positioning mechanism by the pushing mechanism. The flywheel casting is clamped and fixed up and down by the positioning mechanism. After the outer surface of the flywheel casting is ground by the grinding mechanism, finally, the ground flywheel casting is conveyed and discharged by the discharging conveying roller.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0086] Please refer to Figures 1 to 12 , the technical solutions provided by the present invention specifically include the following embodiments:

[0087] An automatic grinding device for flywheel castings, comprising a base 100, a grinding mechanism 200, a feeding conveyor roller 300, a discharging conveyor roller 400, a positioning mechanism 500 and a pushing mechanism 600.

The positioning mechanism 500 is fixedly arranged at the top of the base 100 and is located between the feeding conveyor roller 300 and the discharging conveyor roller 400. Through the positioning of the flywheel casting, the pushing mechanism 600 is fixedly arranged at the top of the feeding conveyor roller 300 and the discharging conveyor roller 400 for transporting the flywheel casting. The flywheel casting is transported by the feeding conveyor roller 300, and then the flywheel casting transported to the end of the feeding conveyor roller 300 is pushed to the top of the positioning mechanism 500 by the pushing mechanism 600. The flywheel casting is clamped and fixed up and down by the positioning mechanism 500. The outer surface of the flywheel casting is ground by the grinding mechanism 200.

[0088] Further, specifically refer to Figures 7 to 11 as shown in

[0089] The grinding mechanism 200 includes an X-axis moving unit 201, a Z-axis moving unit 202, a Y-axis moving unit 203, a loading plate 204, a shaft pin 205, a swing plate 206, a shifting block 207, a fixed angle bracket 208, a smooth rod 209, a positive and negative lead screw 2010, an adjusting seat 2011, a limit pin 2012, a handwheel 2013, a grinding motor 2014, a driving synchronous pulley 2015, a bearing seat 2016, a grinding shaft 2017, a driven synchronous pulley 2018, a synchronous belt 2019, a grinding disc 2020, a spring piece 2021 and a retaining pin 2022. The X-axis moving unit 201 is fixedly installed on the top of the base 100. The Z-axis moving unit 202 is fixedly installed at the output end of the X-axis moving unit 201. The Y-axis moving unit 203 is fixedly installed at the output end of the Z-axis moving unit 202. The loading plate 204 is fixedly installed at the output end of the Y-axis moving unit 203. The shaft pin 205 is rotatably installed inside the loading plate 204. The swing plate 206 is fixedly installed at the front end of the shaft pin 205. The shifting block 207 is fixedly installed at the right end of the swing plate 206. The fixed angle brackets 208 are vertically distributed and fixedly installed on the side of the Y-axis moving unit 203. The smooth rod 209 is fixedly installed between the upper and lower fixed angle brackets 208. The positive and negative lead screw 2010 is rotatably installed between the upper and lower fixed angle brackets 208. The adjusting seats 2011 are vertically distributed and slidably installed on the periphery of the smooth rod 209 and are connected to the positive and negative lead screw 2010 through threaded fit. The limit pins 2012 are fixedly installed on the front of the two adjusting seats 2011 and are respectively located at the bottom and top of the shifting block 207. The handwheel 2013 is fixedly installed on the top of the positive and negative lead screw 2010. The grinding motor 2014 is fixedly installed on the front of the swing plate 206. The driving synchronous pulley 2015 is fixedly installed on the output shaft of the grinding motor 2014. The bearing seat 2016 is fixedly installed on the front of the swing plate 206 and is located at the bottom of the grinding motor 2014. The grinding shaft 2017 is rotatably installed inside the bearing seat 2016. The driven synchronous pulley 2018 is fixedly installed at the end of the grinding shaft 2017. The synchronous belt 2019 is sleeved on the peripheries of the driven synchronous pulley 2018 and the driving synchronous pulley 2015. The grinding disc 2020 is fixedly installed at one end of the grinding shaft 2017 away from the driven synchronous pulley 2018. The spring piece 2021 is fixedly installed inside the shaft pin 205 and extends through the outer wall of the shaft pin 205 to its periphery. The retaining pins 2022 are vertically distributed and fixedly installed at the left end and right end of the front of the loading plate 204. The spring piece 2021 is clamped between the upper and lower retaining pins 2022.

[0090] Specifically, the X-axis moving unit 201, Z-axis moving unit 202, and Y-axis moving unit 203 in the grinding mechanism 200 drive the loading plate 204 to move in the X-axis, Y-axis, and Z-axis directions. The movement of the loading plate 204 drives the swing plate 206, bearing seat 2016, and grinding disc 2020 to move together, so that the side surface of the grinding disc 2020 contacts the side surface of the flywheel casting. Subsequently, the output shaft of the grinding motor 2014 drives the active synchronous pulley 2015 to rotate. Further, under the connection action of the synchronous belt 2019, the driven synchronous pulley 2018 is driven to rotate. The rotation of the driven synchronous pulley 2018 further drives the grinding disc 2020 to rotate through the grinding shaft 2017 to grind the outer surface of the flywheel casting. At the same time, the Y-axis moving unit 203 drives the loading plate 204 to move up and down reciprocally, and further drives the grinding disc 2020 to move up and down reciprocally through the swing plate 206. At the same time, the up and down reciprocating movement of the swing plate 206 also drives the dial block 207 to move together, so that the dial block 207 continuously contacts the outer walls of the upper and lower limit pins 2012, so that the swing plate 206 drives the shaft pin 205 to reciprocally twist a certain angle in the positive and negative directions along the inner wall of the loading plate 204, causing the elastic piece 2021 to undergo elastic deformation. The positive and negative reciprocation of the swing plate 206 also drives the grinding disc 2020 to twist together, realizing chamfering and grinding of the corners of the flywheel casting, ensuring that the corners of the flywheel casting are round. At the same time, in this device, by rotating the handwheel 2013, the positive and negative lead screw 2010 is driven to rotate, so that the distance between the upper and lower adjusting seats 2011 can be adjusted, thereby driving the limit pins 2012 to be adjusted together. At the same time, the distance that the Y-axis moving unit 203 drives the loading plate 204 to move up and down reciprocally needs to be adjusted correspondingly to the distance between the two limit pins 2012, which is convenient for grinding and processing flywheel castings of different thicknesses.

[0091] Further, specifically refer to Figure 5 , Figure 6 as shown:

[0092] The positioning mechanism 500 includes a profile frame 501, a fixed seat 502, a clamping cylinder 503, a chuck 504, a first guide rod 505, a bearing frame 506, a support seat 507, a rotating motor 508, a bracket 509, a lifting cylinder 5010, a lifting angle plate 5011, a bridging plate 5012, a round opening 5013, a guide post 5014, a support slide 5015, an arc-shaped groove 5016 and a baffle 5017. The profile frame 501 is fixedly installed on the tops of the loading conveyor roller 300 and the unloading conveyor roller 400. The fixed seat 502 is fixedly installed inside the profile frame 501. The clamping cylinder 503 is fixedly installed at one end of the top of the fixed seat 502. The chuck 504 is rotatably installed at the bottom of the output rod of the clamping cylinder 503 through a universal connector. The first guide rod 505 is fixedly installed at both ends of one side surface of the fixed seat 502 close to the clamping cylinder 503. The bearing frame 506 is slidably installed on the outer periphery of the two first guide rods 505 and is fixedly connected to the outer wall of the output rod of the clamping cylinder 503. The support seat 507 is fixedly installed on the top of the base 100 and is located between the loading conveyor roller 300 and the unloading conveyor roller 400. The rotating motor 508 is fixedly installed on the inner side surface of the top of the support seat 507. The bracket 509 is fixedly installed on the top of the output shaft of the rotating motor 508. The lifting cylinder 5010 is fixedly installed on the side of the support seat 507. The lifting angle plate 5011 is fixedly installed on the top of the output rod of the lifting cylinder 5010. The bridging plate 5012 is fixedly installed on the side surface of the lifting angle plate 5011. The round opening 5013 is penetrated and opened on the top of the bridging plate 5012. The guide post 5014 is fixedly installed at the four corners of the bottom of the bridging plate 5012 and is slidably connected to the support seat 507 through linear bearings. The support slide 5015 is fixedly installed at both ends of the top of the bridging plate 5012. The arc-shaped groove 5016 is opened in the middle of the opposite surfaces of the two support slides 5015. The baffle 5017 is fixedly installed on the top of the bridging plate 5012.

[0093] Specifically, the flywheel casting located at the end of the feeding conveyor roller 300 is pushed by the feeding mechanism 600 onto the tops of the two supporting slide bars 5015 in the positioning mechanism 500. And under the lateral limiting effect of the baffle 5017, it can be ensured that the flywheel casting does not move laterally. Until the flywheel casting moves to the positions of the two arc grooves 5016, the supporting slide bars 5015 lose the supporting effect on the flywheel casting. The flywheel casting slides downward from the inside of the two arc grooves 5016 under its own gravity until the bottom of it contacts the top of the bracket 509. Thus, the flywheel casting is supported by the bracket 509. Subsequently, the output rod of the clamping cylinder 503 pushes the chuck 504 downward to make the bottom of the chuck 504 abut against the top center of the flywheel casting. Thus, in cooperation with the bracket 509, the upper and lower clamping effect on the flywheel casting is achieved, so that the flywheel casting will not loosen. After the flywheel casting is completely clamped, the output rod of the lifting cylinder 5010 retracts downward, and then drives the bridging plate 5012 to move downward through the lifting angle plate 5011. And the downward movement of the bridging plate 5012 can move more stably through the sliding connection of the four guiding columns 5014 and the support seat 507. At the same time, the downward movement of the bridging plate 5012 further drives the supporting slide bars 5015 and the baffle 5017 to move downward together. Subsequently, the output shaft of the rotating motor 508 drives the bracket 509 to rotate, and then drives the clamped flywheel casting to rotate. Thus, in cooperation with the rotating grinding disc 2020, the surface of the flywheel casting is circumferentially ground.

[0094] Further, specifically referring to Figure 4 、 Figure 12 as shown in

[0095] The feeding mechanism 600 includes a second guiding rod 601, a carriage 602, a pushing frame 603, a telescopic rod 604, a pushing plate 605, a lifting cylinder 606, an internally threaded tube 607, a screw 608 and a servo motor 609. The second guiding rod 601 is fixedly installed at the front end and the rear end of the top of the profile frame 501. The carriage 602 is slidably installed on the outer periphery of the front and rear second guiding rods 601. The carriage 602 is located on the top of the feeding conveyor roller 300. The pushing frame 603 is fixedly installed at the bottom of the carriage 602. The telescopic rods 604 are distributed front and rear and slidably installed inside the pushing frame 603. The pushing plate 605 is fixedly installed at the bottoms of the front and rear telescopic rods 604. The lifting cylinder 606 is fixedly installed on the inner side of the bottom of the pushing frame 603, and the bottom of its output rod is fixedly connected to the top of the pushing plate 605. The internally threaded tube 607 is fixedly installed inside the carriage 602 and is located between the front and rear second guiding rods 601. The screw 608 is threadedly connected inside the internally threaded tube 607. The servo motor 609 is fixedly installed at one end of the top of the profile frame 501, and the end of its output shaft is fixedly connected to the end of the screw 608 through a coupling.

[0096] Specifically, the flywheel casting is transported to one end close to the positioning mechanism 500 by the feeding conveyor roller 300. The output rod of the lifting cylinder 606 drives the push plate 605 to move downward to the side of the flywheel casting. The push plate 605 is slidably connected to the push frame 603 through two telescopic rods 604, enabling more stable up-and-down movement. Subsequently, the output shaft of the servo motor 609 drives the screw 608 to rotate. Since the screw 608 is threadedly connected to the internally threaded tube 607, when the screw 608 rotates, it pushes the internally threaded tube 607 together with the carriage 602 to translate along the axis of the two second guide rods 601. At the same time, the carriage 602 also drives the push frame 603 and the push plate 605 to move together, pushing the flywheel casting at the end of the feeding conveyor roller 300 towards the top of the positioning mechanism 500. After grinding is completed, the output rod of the lifting cylinder 5010 pushes the lifting angle plate 5011 upward, thereby driving the bridging plate 5012, the support slide bar 5015, and the baffle 5017 to move together, making the top height of the support slide bar 5015 flush with the bottom height of the flywheel casting on the top of the bracket 509. Subsequently, the output rod of the clamping cylinder 503 drives the chuck 504 to move upward, and the next flywheel casting to be ground located on the top of the feeding conveyor roller 300 is pushed towards the top of the positioning mechanism 500 by the feeding mechanism 600. When the outer wall of this flywheel casting contacts the outer wall of the ground flywheel casting, the flywheel casting located on the top of the bracket 509 is pushed onto the top of the two support slide bars 5015 again. Subsequently, the output rod of the lifting cylinder 5010 drives the lifting angle plate 5011 to move upward again, causing the bridging plate 5012 to drive the support slide bar 5015 and the baffle 5017 to move up to the original height. The next flywheel casting to be ground is pushed onto the top of the bracket 509 by the feeding mechanism 600. At the same time, the ground flywheel casting is pushed onto the top of the discharging conveyor roller 400 by using this flywheel casting. The ground flywheel casting is transported to the discharging station through the discharging conveyor roller 400, realizing automatic discharging after grinding of the flywheel casting.

[0097] When an automatic grinding device for a flywheel casting works according to this solution, the flywheel casting is transported to one end close to the positioning mechanism 500 by the feeding conveyor roller 300. The output rod of the lifting cylinder 606 drives the push plate 605 to move downward to the side of the flywheel casting. The push plate 605 is slidably connected to the push frame 603 through two telescopic rods 604, and can move up and down more stably. Subsequently, the output shaft of the servo motor 609 drives the screw 608 to rotate. Since the screw 608 is threadedly connected to the internally threaded tube 607, when the screw 608 rotates, it pushes the internally threaded tube 607 together with the carriage 602 to translate along the axis of the two second guide rods 601. At the same time, the carriage 602 also drives the push frame 603 and the push plate 605 to move together, pushing the flywheel casting at the end of the feeding conveyor roller 300 towards the top of the positioning mechanism 500. Subsequently, the flywheel casting enters the tops of the two support slide bars 5015, and under the lateral limiting effect of the baffle 5017, it can be ensured that the flywheel casting will not move laterally. Until the flywheel casting moves to the positions of the two arc grooves 5016, the support slide bars 5015 lose the supporting effect on the flywheel casting, and the flywheel casting slides downward from the inside of the two arc grooves 5016 under the action of its own gravity until its bottom contacts the top of the bracket 509, so as to support the flywheel casting through the bracket 509. Subsequently, the output rod of the clamping cylinder 503 pushes the chuck 504 to move downward, so that the bottom of the chuck 504 abuts against the top center of the flywheel casting, thereby cooperating with the bracket 509 to achieve the effect of clamping the flywheel casting up and down, so that the flywheel casting will not loosen. After the flywheel casting is completely clamped, the output rod of the lifting cylinder 5010 retracts downward, and then drives the bridging plate 5012 to move downward through the lifting angle plate 5011. The downward movement of the bridging plate 5012 can move more stably through the sliding connection of the four guide posts 5014 and the support seat 507. At the same time, the downward movement of the bridging plate 5012 further drives the support slide bars 5015 and the baffle 5017 to move downward together. Subsequently, the output shaft of the rotating motor 508 drives the bracket 509 to rotate, and then drives the clamped flywheel casting to rotate;

[0098] Subsequently, the loading plate 204 is driven to move in the X-axis, Y-axis, and Z-axis directions by the X-axis moving unit 201, Z-axis moving unit 202, and Y-axis moving unit 203 in the grinding mechanism 200. The movement of the loading plate 204 drives the swing plate 206, bearing seat 2016, and grinding disc 2020 to move together, so that the side surface of the grinding disc 2020 contacts the side surface of the flywheel casting. Subsequently, the output shaft of the grinding motor 2014 drives the active synchronous pulley 2015 to rotate. Further, under the connection of the synchronous belt 2019, the driven synchronous pulley 2018 is driven to rotate. The rotation of the driven synchronous pulley 2018 further drives the grinding disc 2020 to rotate through the grinding shaft 2017 to grind the outer surface of the flywheel casting. At the same time, the Y-axis moving unit 203 drives the loading plate 204 to reciprocate up and down, and further drives the grinding disc 2020 to reciprocate up and down through the swing plate 206. At the same time, the reciprocating movement of the swing plate 206 up and down also drives the dial block 207 to move together, so that the dial block 207 continuously contacts the outer walls of the upper and lower limit pins 2012, so that the swing plate 206 drives the shaft pin 205 to reciprocate forward and backward along the inner wall of the loading plate 204 by a certain angle, causing the elastic piece 2021 to undergo elastic deformation. The forward and backward reciprocation of the swing plate 206 also drives the grinding disc 2020 to twist together, realizing chamfering and grinding of the corners of the flywheel casting, ensuring that the corners of the flywheel casting are round. At the same time, in this device, by rotating the handwheel 2013, the reverse screw rod 2010 rotates, so that the distance between the upper and lower adjusting seats 2011 can be adjusted, thereby driving the limit pins 2012 to be adjusted together. At the same time, the distance that the Y-axis moving unit 203 drives the loading plate 204 to reciprocate up and down needs to be adjusted correspondingly to the distance between the two limit pins 2012, which is convenient for grinding and processing flywheel castings of different thicknesses;

[0099] Subsequently, the output rod of the lifting cylinder 5010 pushes the lifting angle plate 5011 upward, thereby driving the bridging plate 5012, the support slide bar 5015, and the baffle 5017 to move together, making the top height of the support slide bar 5015 flush with the bottom height of the flywheel casting at the top of the bracket 509. Subsequently, the output rod of the clamping cylinder 503 drives the chuck 504 to move upward, and through the feeding mechanism 600, the next flywheel casting to be polished located at the top of the feeding conveyor roller 300 is pushed toward the top of the positioning mechanism 500. At the same time, after the outer wall of this flywheel casting contacts the outer wall of the polished flywheel casting, the flywheel casting located at the top of the bracket 509 is pushed onto the tops of the two support slide bars 5015 again. Subsequently, the output rod of the lifting cylinder 5010 drives the lifting angle plate 5011 to move upward again, causing the bridging plate 5012 to drive the support slide bar 5015 and the baffle 5017 to move up to the original height. The next flywheel casting to be polished is pushed to the top of the bracket 509 through the feeding mechanism 600. At the same time, the polished flywheel casting is pushed to the top of the discharging conveyor roller 400 by using this flywheel casting, and the polished flywheel casting is transported to the discharging station through the discharging conveyor roller 400, realizing the automatic discharging after the flywheel casting is polished.
