Description

Technical Field

[0001] The invention relates to the technical field of flywheel polishing devices, in particular to a flywheel casting polishing device. Background Art

[0002] A flywheel is a disc-shaped component with a large moment of inertia that acts 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 also unstable. To improve this situation, a flywheel is installed at the rear end of the crankshaft.

[0003] The Chinese patent with application date: 2021-06-22 and publication number: CN113400110A discloses a grinding device for flywheel castings, which relates to the technical field of grinding equipment. The present invention includes an electric push rod installed on the upper side of the base plate, a first motor installed in the output end of the electric push rod, a rotating cylinder installed in the output end of the first motor, a fixed cylinder located in the rotating cylinder, and a sliding column elastically and slidingly matched in the fixed cylinder; four slideways are provided on the outer wall of the sliding column, and a first limit block and a sliding block elastically and slidingly matched with the first limit block are installed inside the slideway. The present invention facilitates the grinding of the flywheel body and increases the grinding speed by installing a grinding mechanism for grinding the flywheel body on the outer wall of the rotating cylinder. 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.

[0004] However, both sides of the flywheel have stepped surfaces, and burrs are likely to appear on both sides of the flywheel casting. Therefore, it is necessary to grind and polish both sides of the flywheel casting. However, after the flywheel casting is fixed with a clamp, generally only one of the surfaces can be polished. When polishing the other surface, the flywheel casting needs to be removed first and then mounted on the clamp in reverse. The operation process is relatively cumbersome, and further improvements can be made. Summary of the Invention

[0018] (3) Beneficial effects

[0019] Compared with the prior art, the present invention provides a flywheel casting grinding device with the following beneficial effects:

[0020] 1. The flywheel casting grinding device drives the scroll plate to rotate by driving motor 2, driving the transverse block and the inner clamping plate to move outward along the linear groove, so that the inner clamping plate is clamped on the flywheel casting from the inside; at the same time, the rack plate 3 moves outward, driving gear 2 to rotate, so that the rack plate 2, the arc frame, and the connecting plate move inward, and the outer clamping plate is clamped on the outside of the flywheel casting. The limiting boss restricts the rotation of the flywheel casting, thereby completing the fixation of the flywheel casting; thereby achieving a good fixation effect on the flywheel casting and facilitating the grinding and polishing;

[0021] 2. The flywheel casting grinding device can move along the X-axis, Y-axis and Z-axis through the mounting seat, so that the grinding head assembly can move synchronously along the X-axis, Y-axis and Z-axis. The position of the grinding head assembly is adjusted so that the grinding head assembly can be aligned with the left side of the flywheel casting. After that, the grinding head assembly is moved horizontally to the right, so that the circular grinding head and the annular grinding head can be attached to the surface of the flywheel casting. The grinding head assembly is then driven to rotate by the rotating drive member to grind and polish the left side of the flywheel casting. Thus, through the machine tool form design, each functional component is independently formed into a module, which is convenient for assembly, debugging and maintenance. During operation, the component structure of the three-dimensional moving drive member works together to accurately position the grinding head assembly to the casting surface for grinding operations. At the same time, safety protection measures such as distance sensors and drag chains ensure the safety and reliability of the operation process.

[0022] 3. The flywheel casting grinding device can slide relative to the right turntable through the sliding rod and the square sliding column, so that the annular grinding head and the sliding rod can adapt to the stepped side of the flywheel casting. The elasticity of the second spring and the fixed ring allows the circular grinding head and the annular grinding head to fit tightly against the side of the flywheel casting, thereby achieving the purpose of ensuring the grinding effect on the stepped surface of the flywheel casting.

[0023] When the gear is moved to the right end, the inner plate is inserted into the left center of the flywheel casting until the inner plate is fitted on the connecting shaft, the inner support cylinder is inserted into the countersunk hole of the flywheel casting, and the sealing cap is engaged with the sliding cylinder; the vortex disk is driven by the driving motor 2 to rotate in the opposite direction, so that the inner and outer splints are away from the flywheel casting, releasing the fixing effect of the flywheel casting; and the sealing cap and the threaded rod are driven to rotate by the connecting shaft, so that the sliding cylinder and the extension bar move to the right, the inclined part of the guide groove squeezes the fixed column, and the L-shaped stop bar extends from the circumferential surface of the inner support cylinder, so that the L-shaped stop bar cooperates with the embedded disk to clamp the two sides of the flywheel casting; thereby achieving the purpose of convenient switching of the fixed state of the flywheel casting.

[0054] See also Figure 6-Figure 7 Because the two sides of the flywheel casting are stepped, a retractable grinding structure is provided on the grinding head assembly 400 to ensure the grinding effect of the flywheel casting.

[0055] See also Figure 8Two guide frames 501 are fixedly mounted on the top of the support frame 500. The two guide frames 501 are arranged front to back. A fixed arm 700 is fixedly mounted on the right end of the guide frames 501. A slider 502 is slidably connected within each guide frame 501. A linear motion driver 205 is provided inside the support frame 500. A connecting collar 505 is fixedly mounted on the output end of the linear motion driver 205, wherein a threaded collar 2053 serves as the output end of the linear motion driver 205. The connecting collar 505 is located between the two sliders 502. A rotating shaft assembly is fixedly mounted on the front end of the movable arm 600. The rotating shaft assembly is rotatably connected to the connecting collar 505 and the center of the two sliders 502. A gear 1 504 is fixedly mounted on the front end of the rotating shaft assembly. A rack plate 1 503 is fixedly mounted on the middle of the top front portion of the support frame 500.

[0056] As the slider 502 slides along the guide frame 501, gear 1 504 engages with rack plate 1 503, causing gear 1 504 to rotate 180°. Consequently, as the slider 502 moves along the guide frame 501, the movable arm 600 itself rotates 180°. Consequently, when the slider 502 moves to either end of the guide frame 501, the left-side fixing members 800 are located on either side of the movable arm 600. When the slider 502 is located at the right end of the guide frame 501, the flywheel casting secured to the right-side fixing member 900 can be transferred to the left-side fixing member 800. When the slider 502 moves to the left end of the guide frame 501, both the flywheel casting and the left-side fixing member 800 are located on the left side of the movable arm 600. Therefore, when the flywheel casting is fixed on the left fixing member 800 and the right fixing member 900 respectively, the exposed sides of the flywheel casting are all facing the left, thereby adapting the grinding head assembly 400 to be fixed on the right side of the drive shaft 303, facilitating grinding and polishing of both sides of the flywheel casting.

[0057] See also Figure 9 The rotating shaft assembly includes a rotating shaft 601 fixedly mounted on the front end of the movable arm 600, and two limit plates 602 are fixedly mounted on both ends of the rotating shaft 601, and the two limit plates 602 are respectively clamped on the front and rear sides of the slider 502, and the gear 1 504 is fixedly mounted on the front end of the rotating shaft 601, and the rotating shaft 601 is rotatably connected to the center of the slider 502 and the connecting ring 505; slots 603 are arranged in an array on the circumferential surfaces of both ends of the rotating shaft 601, and the slots 603 are isosceles trapezoidal, and the inner wall of each slider 502 is arranged with mounting holes 604 in an array, and a clamping column 605 is slidably connected in the mounting hole 604, and a spring 3 606 is fixedly mounted between the clamping column 605 and the inner wall of the mounting hole 604.

[0058] The end of the latch 605, located outside the mounting hole 604, is hemispherical, and the hemispherical end of the latch 605 abuts against the inner wall of the slot 603. The elasticity of spring three 606 keeps the latch 605 locked within the slot 603, inhibiting rotation of the rotating shaft 601 relative to the slider 502 and the connecting collar 505. This allows the movable arm 600 to remain stable and prevent erroneous rotation before the gear 1 504 passes through the rack plate 1 503. When the gear 1 504 passes through the rack plate 1 503, the gear 1 504 and the rotating shaft 601 rotate, and the rotating shaft 601, located on the side wall of the slot 603, compresses the hemispherical end of the latch 605, allowing the latch 605 to move into the mounting hole 604 and clear the slot 603. The elasticity of spring three 606 then allows the latch 605 to spring into the next slot 603.

[0059] See also Figure 11-12 The right side fixing part 900 includes a circular cover 901 fixedly mounted on the left side of the rear end of the fixed arm 700, and a linear groove 902 is opened in the array on the left side of the circular cover 901. A vortex disk 903 is rotatably connected inside the circular cover 901, and a vortex groove is opened on the left side of the vortex disk 903. A driving motor 2 904 is fixedly mounted on the right side of the rear end of the fixed arm 700, and the output end of the driving motor 2 904 is fixedly mounted at the center of the vortex disk 903. An inner splint 907 is slidably connected in the linear groove 902, and a transverse block 906 is fixedly mounted on the right side of the inner splint 907. The transverse block 906 is threadedly connected to the vortex disk 903, and a sealing strip 908 is fixedly mounted on the left side of the transverse block 906. The sealing strip 908 covers the opening on the right side of the linear groove 902. The scroll plate 903 is rotated by drive motor 2 904, driving the transverse block 906 and inner clamping plate 907 to slide along the linear groove 902. This causes the inner clamping plate 907 to fit against the right sidewall of the flywheel casting, thereby clamping and securing the flywheel casting from the inside. Furthermore, as the transverse block 906 moves, the sealing strip 908 maintains its sealing effect on the linear groove 902.

[0060] See also Figure 10-13 A connecting shaft 905 is fixedly mounted at the center of the left side of the vortex disk 903. The connecting shaft 905 is rotatably connected to the center of the circular cover 901. The cross-section of the connecting shaft 905 is in the shape of a "convex" character. The left half of the connecting shaft 905 is inserted into the center of the flywheel casting, which can play a role in auxiliary support of the flywheel casting and prevent the debris generated by cutting from entering the center hole of the flywheel casting. When the left side of the flywheel casting is polished, the slider 502 can be moved to the right along the guide frame 501 to make the left side fixing member 800 close to the left side of the flywheel casting, so as to facilitate the transfer of the flywheel casting to the left fixing member 800.

[0061] The left-side fixing member 800 includes an embedded disc 801 fixedly mounted on the left side of the rear end of the movable arm 600. The embedded disc 801 is designed to be inserted into the center of the left side of the flywheel casting and fit into the left side of the connecting shaft 905. An inner support tube 802 is fixed to the left side of the embedded disc 801. The inner support tube 802 is designed to be inserted into the countersunk hole in the middle of the flywheel casting. A threaded rod 803 is rotatably connected to the inner support tube 802. A sealing cap 804 is fixed to the left end of the threaded rod 803. The diameter of the sealing cap 804 is equal to the outer diameter of the inner support tube 802, and the sealing cap 804 seals the opening of the inner support tube 802. The right half of the circumference of the connecting shaft 905 is provided with an array of meshing teeth, and the circumference of the sealing cap 804 is provided with an array of meshing grooves. After the threaded rod 803 is inserted into the countersunk hole of the flywheel casting, the connecting shaft 905 and the sealing cap 804 engage with each other. The second drive motor 904 then drives the scroll plate 903 to rotate in the opposite direction, moving the inner clamping plate 907 away from the flywheel casting, thereby releasing the fixing effect of the right fixing member 900 on the flywheel casting. At the same time, the scroll plate 903 drives the connecting shaft 905 to rotate synchronously, thereby driving the sealing cap 804 and the threaded rod 803 to rotate.

[0062] A sliding cylinder 805 is threadedly connected to the threaded rod 803. A threaded hole is defined at the right end of the sliding cylinder 805, allowing it to slide within the inner support cylinder 802. A plurality of extension bars 806 are fixedly mounted on the left end of the sliding cylinder 805. Each extension bar 806 has two guide slots 807 extending therethrough. The left half of the guide slots 807 are horizontal, while the right half is inclined. An array of L-shaped retaining bars 808 are slidably connected to the circumference of the left end of the inner support cylinder 802. Each L-shaped retaining bar 808 is positioned between two extension bars 806. Two fixed posts 809 are fixedly mounted on either side of the horizontal portion of the L-shaped retaining bar 808, which slides within the guide slots 807.

[0063] The threaded rod 803 rotates, driving the sliding cylinder 805 and extension bar 806 to the right. The inclined portion of the guide groove 807 squeezes the fixed column 809, causing the L-shaped retaining bar 808 to extend from the circumference of the inner support cylinder 802. The vertical portion of the L-shaped retaining bar 808 abuts against the right side wall of the flywheel casting counterbore. Thus, by inserting multiple inner support cylinders 802 into the counterbore, the flywheel casting is supported and restrained from rotating during grinding. Simultaneously, the embedded disc 801 and L-shaped retaining bar 808 clamp onto both sides of the flywheel casting, preventing it from moving left or right.

[0064] See also Figure 11-13An arc frame 909 is arranged in an array on the outer side of the circumference of the circular cover 901. The arc frame 909 corresponds to the transverse block 906 one by one. Rack plates 2 910 are fixedly installed at both ends of the arc frame 909. A plurality of avoidance grooves 911 are opened through the circumference of the circular cover 901. Rack plates 2 910 are inserted into the avoidance grooves 911. Rack plates 3 913 are fixedly installed on both sides of the sealing strip 908. Gear 2 912 is provided between rack plate 2 910 and rack plate 3 913. Gear 2 912 is rotatably connected to the inner wall of the circular cover 901.

[0065] A connecting plate 914 is fixedly mounted on the left middle portion of the curved frame 909. An outer plate 915 is fixedly mounted on the end of the connecting plate 914 away from the curved frame 909. This outer plate 915 fits against the circumferential surface of the flywheel casting. A limiting boss 916 is fixedly mounted on the outer plate 915. This boss 916 engages a ring gear on the surface of the flywheel casting. When the inner plate 907 moves outward along the linear groove 902, it drives gear 2 912 to rotate via rack plate 3 913, which in turn drives rack plate 2 910, the curved frame 909, and the connecting plate 914 inward, clamping the outer plate 915 against the outer side of the flywheel casting. The limiting action of the limiting boss 916 prevents the flywheel casting from rotating during the grinding process.

[0066] During use, first, the scroll plate 903 is driven to rotate by the second drive motor 904, driving the transverse block 906 and the inner clamping plate 907 to move outward along the linear groove 902, so that the inner clamping plate 907 is clamped on the flywheel casting from the inside; at the same time, the rack plate 3 913 moves outward, driving the second gear 912 to rotate, so that the rack plate 2 910, the arc frame 909, and the connecting plate 914 move inward, and the outer clamping plate 915 is clamped on the outside of the flywheel casting. The limiting boss 916 restricts the rotation of the flywheel casting, thereby completing the fixation of the flywheel casting;

[0067] The mounting base 204 can be moved along the X-axis, Y-axis, and Z-axis directions, so that the grinding head assembly 400 can be moved synchronously along the X-axis, Y-axis, and Z-axis directions. The position of the grinding head assembly 400 is adjusted so that the grinding head assembly 400 can be aligned with the left side of the flywheel casting. Then, the grinding head assembly 400 is moved horizontally to the right, so that the circular grinding head 404 and the annular grinding head 407 are attached to the surface of the flywheel casting. Then, the grinding head assembly 400 is driven to rotate by the rotating driving member 300 to grind and polish the left side of the flywheel casting.

[0068] Then, the grinding head assembly 400 is moved away from the flywheel casting and over the movable arm 600 until the grinding head assembly 400 is on the left side of the left fixing member 800;

[0069] The linear motion drive member 205 then drives the connecting ring 505 to move rightward, and the slider 502 slides rightward along the guide frame 501. When the gear 1 504 passes the rack plate 1 503, the rotating shaft 601 and the movable arm 600 rotate, causing the left fixing member 800 to deflect to the right side of the movable arm 600. After the gear 1 504 moves away from the rack plate 1 503, the spring 3 606 causes the clamping column 605 to be clamped in the clamping slot 603, preventing the movable arm 600 from rotating accidentally.

[0070] When the slider 502 moves to the right end of the guide frame 501, the embedded disc 801 is inserted into the center of the left side of the flywheel casting until the embedded disc 801 fits on the connecting shaft 905, the inner support cylinder 802 is inserted into the countersunk hole of the flywheel casting, and the sealing cap 804 is engaged with the sliding cylinder 805;

[0071] Then, the second drive motor 904 drives the vortex disc 903 to rotate in the opposite direction, thereby moving the inner clamping plate 907 and the outer clamping plate 915 away from the flywheel casting, releasing the fixing effect on the flywheel casting; and the connecting shaft 905 drives the sealing cap 804 and the threaded rod 803 to rotate, so that the sliding cylinder 805 and the extension bar 806 move to the right, and the inclined portion of the guide groove 807 squeezes the fixing column 809, and the L-shaped retaining bar 808 extends from the circumferential surface of the inner support cylinder 802, so that the L-shaped retaining bar 808 cooperates with the embedded disc 801 to clamp on both sides of the flywheel casting;

[0072] Afterwards, the linear motion drive member 205 drives the connecting ring 505 to move to the left, and the slider 502 slides to the left along the guide frame 501. When the gear 1 504 passes the rack plate 1 503, the movable arm 600 rotates 180° in the opposite direction, so that the left fixing member 800 and the flywheel casting are deflected to the left side of the movable arm 600, and the flywheel casting is polished again by the polishing head assembly 400.
