Description

Technical Field

[0001] The invention relates to the technical field of workpiece grinding, in particular to automatic grinding equipment for flywheel castings. Background Art

[0002] The flywheel is a disc-shaped component with a large moment of inertia, acting as an energy storage device. In a four-stroke engine, work is performed only during the power stroke, while the exhaust, intake, and compression strokes all consume energy. Consequently, the crankshaft's torque output varies periodically, and the crankshaft speed is unstable. To improve this, a flywheel is installed at the rear end of the crankshaft. It is usually made of cast metal, and the blank requires finishing and polishing.

[0003] According to a Chinese patent with 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 wall of the rotating cylinder, the grinding of the flywheel body is facilitated and the grinding speed is increased. The setting of the slideway enables the sliding block to rotate the first rotating plate under the drive of the fixed cylinder, so that the grinding mechanism drives the telescopic plate to position and release the flywheel body, thereby improving the stability of the flywheel body during grinding. After using the above-mentioned automatic grinding device for flywheel castings, it was found that the device cannot grind the edges and corners of the flywheel rounded, resulting in burrs on the edges and corners of the flywheel after grinding, so further processing is required, which makes the grinding steps of the flywheel complicated and not simple enough.

The X-axis moving unit 201 is fixedly mounted on the top of the base 100. The Z-axis moving unit 202 is fixedly mounted on the output end of the X-axis moving unit 201, the Y-axis moving unit 203 is fixedly mounted on the output end of the Z-axis moving unit 202, the loading plate 204 is fixedly mounted on the output end of the Y-axis moving unit 203, the shaft pin 205 is rotatably mounted on the inside of the loading plate 204, the swing plate 206 is fixedly mounted on the front end of the shaft pin 205, the shift block 207 is fixedly mounted on the right end of the swing plate 206, the fixed angle code 208 is fixedly mounted on the side of the Y-axis moving unit 203 in an upper and lower distribution, the light rod 209 is fixedly mounted between the upper and lower fixed angle codes 208, and the forward and reverse screw rods 2010 are rotatably mounted on the upper Between the lower two fixed angle codes 208, the adjustment seat 2011 is slidably installed on the periphery of the polished rod 209 and is connected to the positive and negative screw rods 2010 by threaded connection. The limit pin 2012 is fixedly installed on the front of the two adjustment seats 2011 and is respectively located at the bottom and top of the dial block 207. The handwheel 2013 is fixedly installed on the top of the positive and negative screw rods 2010. The grinding motor 2014 is fixedly installed on the front of the swing plate 206. The active synchronous wheel 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 mounted inside the bearing seat 2016, the driven synchronous wheel 2018 is fixedly mounted on the end of the grinding shaft 2017, the synchronous belt 2019 is sleeved on the periphery of the driven synchronous wheel 2018 and the active synchronous wheel 2015, the grinding sheet 2020 is fixedly mounted on the end of the grinding shaft 2017 away from the driven synchronous wheel 2018, the spring piece 2021 is fixedly mounted on the inside of the shaft pin 205, and passes through the outer wall of the shaft pin 205 and extends to its periphery, the bayonet 2022 is distributed up and down and fixedly mounted on the front left end and the front right end of the loading plate 204, and the spring piece 2021 is clamped between the upper and lower bayonet pins 2022.

[0090] Specifically, 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, the Z-axis moving unit 202 and the Y-axis moving unit 203 in the grinding mechanism 200. The movement of the loading plate 204 drives the swing plate 206, the bearing seat 2016 and the grinding sheet 220 to move together, so that the side of the grinding sheet 220 contacts the side of the flywheel casting. Subsequently, the output shaft of the grinding motor 2014 drives the active synchronous wheel 2015 to rotate, and further drives the driven synchronous wheel 2018 to rotate under the connection action of the synchronous belt 2019.

The up and down reciprocating movement also drives the shift block 207 to move together, so that the shift block 207 constantly contacts the outer walls of the upper and lower limit pins 2012, thereby causing the swing plate 206 to drive the shaft pin 205 to rotate back and forth along the inner wall of the loading plate 204 by a certain angle, causing the spring piece 2021 to undergo elastic deformation, and the swing plate 206 also drives the grinding sheet 2020 to rotate together, thereby chamfering the edges and corners of the flywheel casting to ensure that the edges and corners of the flywheel casting are rounded. At the same time, in this device, by turning the hand wheel 2013 to drive the forward and reverse screw rods 2010 to rotate, the distance between the upper and lower adjustment 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 back and forth needs to be adjusted accordingly with the distance between the two limit pins 2012, which is convenient for grinding flywheel castings of different thicknesses.

[0091] For further details, please refer to Figure 5 、 Figure 6 As shown:

[0092] The positioning mechanism 500 includes a profile frame 501, a fixing seat 502, a clamping cylinder 503, a chuck 504, a 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 bridge plate 5012, a round mouth 5013, a guide column 5014, a support slide 5015, an arc groove 5016 and a baffle 5017. The profile frame 501 is fixedly mounted on the feeding conveyor roller 300 and The top of the unloading conveying roller 400, the fixed seat 502 is fixedly installed in the interior of 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 No. 1 guide rod 505 is fixedly installed on the two ends of one side of the fixed seat 502 close to the clamping cylinder 503, the bearing frame 506 is slidably installed on the periphery of the two No. 1 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 feeding conveying roller 300 and the unloading conveying roller 400, the rotating motor 508 is fixedly installed on the top inner side surface 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 bridge plate 5012 It is fixedly installed on the side of the lifting angle plate 5011, the circular opening 5013 is opened through the top of the bridge plate 5012, the guide column 5014 is fixedly installed at the four corners of the bottom of the bridge plate 5012, and is slidably connected to the support seat 507 through a linear bearing, the support slide 5015 is fixedly installed at the top two ends of the bridge plate 5012, the arc groove 5016 is opened in the middle of the opposite surfaces of the two support slides 5015, and the baffle 5017 is fixedly installed on the top of the bridge plate 5012.

[0093] Specifically, the flywheel casting located at the end of the feeding conveying roller 300 is pushed to the top of the two supporting slides 5015 in the positioning mechanism 500 by the pushing mechanism 600, and under the lateral limiting action of the baffle 5017, it can be ensured that the flywheel casting will not move laterally until the flywheel casting moves to the position of the two arc-shaped grooves 5016. The supporting slides 5015 then lose their supporting effect on the flywheel casting, and the flywheel casting slides downward from the inside of the two arc-shaped grooves 5016 under the action of its own gravity until its bottom contacts the top of the bracket 509, thereby supporting the flywheel casting through the bracket 509. Subsequently, the output rod of the clamping cylinder 503 pushes the chuck 504 downward to move, so that the bottom of the chuck 504 rests on the top center of the flywheel casting, thereby In conjunction with the bracket 509, the flywheel casting is clamped up and down to prevent it from loosening. After the flywheel casting is completely clamped, the output rod of the lifting cylinder 5010 retracts downward, and then the lifting angle plate 5011 drives the bridge plate 5012 to move downward. The downward movement of the bridge plate 5012 is connected to the sliding connection between the four guide columns 5014 and the support seat 507, so that the movement can be more stable. At the same time, the downward movement of the bridge plate 5012 further drives the support slide 5015 and the baffle 5017 to move downward together. Subsequently, the output shaft of the rotating motor 508 drives the bracket 509 to rotate, thereby driving the clamped flywheel casting to rotate, thereby cooperating with the rotating grinding plate 2020 to perform circular grinding on the surface of the flywheel casting.

[0094] For further details, please refer to Figure 4 、 Figure 12 As shown:

[0095] The pushing mechanism 600 includes a No. 2 guide rod 601, a slide 602, a pusher 603, a telescopic rod 604, a push plate 605, a lifting cylinder 606, an internal threaded tube 607, a screw 608 and a servo motor 609. The No. 2 guide rod 601 is fixedly mounted on the top front end and the top rear end of the profile frame 501, and the slide 602 is slidably mounted on the periphery of the front and rear No. 2 guide rods 601. The slide 602 is located on the top of the feeding conveyor roller 300, and the pusher 603 is fixedly mounted on the bottom of the slide 602. The telescopic rod 604 is slidably mounted on the front and rear sides of the pusher. Inside the frame 603, the push plate 605 is fixedly installed at the bottom of the front and rear telescopic rods 604, the lifting cylinder 606 is fixedly installed on the inner side of the bottom of the push frame 603, and the bottom of its output rod is fixedly connected to the top of the push plate 605, the internal threaded tube 607 is fixedly installed inside the slide 602, and is located between the front and rear No. 2 guide rods 601, the screw 608 is threadedly connected to the inside of the internal threaded tube 607, and 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 near the positioning mechanism 500 by the feeding conveyor roller 300, and the push plate 605 is driven to move downward to the side of the flywheel casting by the output rod of the lifting cylinder 606. 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 screw 608 is driven to rotate by the output shaft of the servo motor 609. Since the screw 608 is threadedly connected to the internal threaded tube 607, when the screw 608 rotates, it pushes The internal threaded tube 607 and the slide 602 move horizontally along the axis of the two No. 2 guide rods 601. At the same time, the slide 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 toward the top of the positioning mechanism 500. After the grinding is completed, the output rod of the lifting cylinder 5010 pushes the lifting angle plate 5011 upward to move, thereby driving the bridge plate 5012, the support slide 5015 and the baffle 5017 to move together, so that the support The top height of the slide 5015 is flush with the bottom height of the flywheel casting on the top of the bracket 509. Then the output rod of the clamping cylinder 503 drives the chuck 504 to move upward, and the next flywheel casting to be polished located on the top of the feeding conveyor roller 300 is pushed to the top of the positioning mechanism 500 through the pushing mechanism 600. At the same time, after the outer wall of the flywheel casting contacts the outer wall of the polished flywheel casting, the flywheel casting on the top of the bracket 509 is pushed to the top of the two supporting slides 5015 again, and then the lifting cylinder is lifted. The output rod of 5010 drives the lifting angle plate 5011 to move upward again, so that the bridge plate 5012 drives the support slide 5015 and the baffle 5017 to move up to the original height, and the next flywheel casting to be polished is pushed to the top of the bracket 509 through the pushing mechanism 600. At the same time, the flywheel casting is used to push the previous polished flywheel casting to the top of the unloading conveyor roller 400, and the polished flywheel casting is transferred to the unloading station through the unloading conveyor roller 400, thereby realizing automatic unloading of the flywheel casting after polishing.

[0097] When the automatic grinding device for flywheel castings of this solution is working, the flywheel casting is transported to one end near the positioning mechanism 500 by the feeding conveyor roller 300, and the push plate 605 is driven to move downward to the side of the flywheel casting by the output rod of the lifting cylinder 606. 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 screw 608 is driven to rotate by the output shaft of the servo motor 609. Since the screw 608 is threadedly connected to the internal threaded tube 607, when the screw 60 8 rotation pushes the internal threaded tube 607 together with the slide 602 to move along the axis of the two No. 2 guide rods 601. At the same time, the slide 602 also drives the push frame 603 and the push plate 605 to move together, pushing the flywheel casting located at the end of the feeding conveyor roller 300 toward the top of the positioning mechanism 500. Subsequently, the flywheel casting enters the top of the two supporting slides 5015 and is limited by the lateral position of the baffle 5017 to ensure that the flywheel casting will not move laterally until the flywheel casting moves to the position of the two arc grooves 5016. After that, the support slide 5015 loses its supporting effect on the flywheel casting, and the flywheel casting slides downward from the two arc-shaped grooves 5016 under the action of its own gravity until its bottom contacts the top of the bracket 509, thereby supporting the flywheel casting through the bracket 509. Subsequently, the output rod of the clamping cylinder 503 pushes the clamp 504 downward to move, so that the bottom of the clamp 504 rests on the top center of the flywheel casting, thereby cooperating with the bracket 509 to achieve the upper and lower clamping effect on the flywheel casting, so that the flywheel casting will not loosen and the flywheel casting is completely fixed. After full clamping, the output rod of the lifting cylinder 5010 retracts downward, thereby driving the bridge plate 5012 downward through the lifting angle plate 5011. The downward movement of the bridge plate 5012 is more stable due to the sliding connection between the four guide columns 5014 and the support base 507. At the same time, the downward movement of the bridge plate 5012 further drives the support slide 5015 and the baffle 5017 to move downward together. Subsequently, the output shaft of the rotating motor 508 drives the bracket 509 to rotate, thereby driving the clamped flywheel casting to rotate.

[0098] Then, the X-axis moving unit 201, the Z-axis moving unit 202 and the 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, the bearing seat 2016 and the grinding sheet 220 to move together, so that the side of the grinding sheet 220 contacts the side of the flywheel casting. Subsequently, the output shaft of the grinding motor 2014 drives the active synchronous wheel 2015 to rotate, and further drives the driven synchronous wheel 2018 to rotate under the connection action of the synchronous belt 2019. The rotation of the driven synchronous wheel 2018 further drives the grinding sheet 220 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 back and forth, and further drives the grinding sheet 220 to move back and forth up and down through the swing plate 206. At the same time, the swing plate 206 The up and down reciprocating movement also drives the shift block 207 to move together, so that the shift block 207 constantly contacts the outer walls of the upper and lower limit pins 2012, thereby causing the swing plate 206 to drive the shaft pin 205 to twist back and forth along the inner wall of the loading plate 204 by a certain angle, causing the spring piece 2021 to undergo elastic deformation, and the swing plate 206 also drives the grinding sheet 2020 to twist together, thereby chamfering the edge corners of the flywheel casting to ensure that the edge corners of the flywheel casting are rounded. At the same time, in this device, by turning the hand wheel 2013, the forward and reverse screw rods 2010 are driven to rotate, so that the distance between the upper and lower adjustment seats 2011 can be adjusted, thereby driving the limit pins 2012 to be adjusted together. At the same time, the Y-axis moving unit 203 drives the loading plate 204 to move back and forth. The distance needs to be adjusted accordingly with the distance between the two limit pins 2012, which is convenient for grinding flywheel castings of different thicknesses.

[0099] Subsequently, the output rod of the lifting cylinder 5010 pushes the lifting angle plate 5011 upward to move, thereby driving the bridge plate 5012, the support slide 5015 and the baffle 5017 to move together, so that the top height of the support slide 5015 is 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 polished located on the top of the feeding conveyor roller 300 is pushed to the top of the positioning mechanism 500 through the pushing mechanism 600. At the same time, after the outer wall of the flywheel casting contacts the outer wall of the polished flywheel casting, the flywheel casting located on the bracket is pushed upward. The flywheel casting at the top of 509 is pushed to the top of the two supporting slides 5015 again, and then the output rod of the lifting cylinder 5010 drives the lifting angle plate 5011 to move upward again, so that the bridge plate 5012 drives the supporting slides 5015 and the baffle 5017 to move up to the original height, and the next flywheel casting to be polished is pushed to the top of the bracket 509 through the pushing mechanism 600. At the same time, the flywheel casting is used to push the previous polished flywheel casting to the top of the unloading conveyor roller 400, and the polished flywheel casting is transferred to the unloading station through the unloading conveyor roller 400, realizing automatic unloading of the flywheel casting after polishing.
