Description

Technical Field

[0001] The present invention belongs to the technical field of polishing devices, and specifically relates to a spherical surface polishing device for the production of ductile iron castings. Background Art

[0002] Ductile iron castings are casting parts made of ductile iron and are widely used in industrial fields such as machinery and automobiles. During the production process of ductile iron castings, there are often burrs on their surfaces. In order to avoid the impact of burrs on the subsequent use of ductile iron castings, it is necessary to polish the surface of ductile iron castings to remove the burrs on their surfaces and make them smoother.

[0003] The patent with the publication number CN222493687U discloses a spherical surface polishing device for the production of ductile iron castings, including a bottom plate; a bracket is installed on the surface of the bottom plate, and a fixed sleeve is installed on the top of the bracket. The spherical surface polishing device for the production of ductile iron castings provided by this patent can make the polishing work of spherical castings easy and labor-saving, and has high polishing accuracy by setting the cooperation of each component. By setting the first screw rod and the second screw rod to adjust the horizontal and vertical positions of the polishing disc respectively, the polishing device can be used more conveniently and has higher applicability. By setting the positioning mechanism and four groups of polishing discs, when polishing castings of different sizes, the replacement of the polishing disc can be made more quickly and conveniently. When polishing spherical castings, the outer frame can effectively prevent debris from splashing outwards, improve the safety of the polishing work, and at the same time avoid the problem of difficult cleaning caused by the scattered debris.

[0004] However, the above technical solution still has the following deficiencies in the actual application process: Since one side of the ductile iron casting has a circular through-hole, the design of the circular through-hole is usually based on functional requirements and process optimization, and such ductile iron castings are relatively common. Therefore, the through-hole of the ductile iron casting is inserted and sleeved on the rotating shaft to fix the ductile iron casting, and then the ductile iron casting is driven to rotate and cooperate with the polishing disc to polish the ductile iron casting. However, when the number of ductile iron castings to be polished is large, if workers manually insert the ductile iron castings onto the rotating shaft, it will result in a high labor intensity. When using a clamping structure such as a manipulator to automatically insert the ductile iron castings onto the rotating shaft, since multiple ductile iron castings may be stacked together, it is difficult for the clamping structure such as a manipulator to pick them up one by one, and at the same time, it is also difficult to accurately align the circular through-hole with the rotating shaft, thus affecting the fixation of the ductile iron casting and the subsequent polishing work.

[0028] One end of the fixed block 31 is fixedly connected to the sixth motor 42, and the output end of the sixth motor 42 is fixedly connected to the adjusting wheel 25.

[0029] Specifically, when the existing spherical surface polishing device for the production of ductile iron castings is in use, since one side of the ductile iron casting has a circular through-hole, the design of the circular through-hole is usually based on functional requirements and process optimization. Such ductile iron castings are relatively common. Therefore, the through-hole of the ductile iron casting is inserted and sleeved on the rotating shaft to fix the ductile iron casting, and then the ductile iron casting is driven to rotate, and the polishing disc is used to polish the ductile iron casting. However, when the number of ductile iron castings to be polished is large, if workers manually insert the ductile iron castings onto the rotating shaft, it will result in a high labor intensity. When using a clamping structure such as a manipulator to automatically insert the ductile iron castings onto the rotating shaft, since multiple ductile iron castings may be stacked together, it is difficult for the clamping structure such as a manipulator to pick them up one by one. At the same time, it is also difficult to accurately align the circular through-hole with the rotating shaft, thus affecting the fixation of the ductile iron casting and the subsequent polishing work. Therefore, in order to solve the above problems, this embodiment is used for the same batch of ductile castings with the same specifications. Since the blanking plate 14 and the elastic pad 15 cooperate with each other to form a funnel-shaped channel, the adjusting ring 11 can be driven up and down by the motor 17 to drive the threaded rod 16 to rotate according to the size of the ductile casting, and the connecting rod 12 drives the distance between the blanking plate 14 and the axis of the support ring 10 to be adjusted. At the same time, the elastic pad 15 will also be deformed until the narrowest part of the entire funnel-shaped channel can only pass one ductile casting at a time, and the ductile castings cannot pass side by side, and then multiple The ductile iron castings are uniformly added to the blanking plate 14, and the ductile iron castings fall under the action of gravity. In addition, the baffle plate 21 in the initial state fits with the bottom of the blanking plate 14, so the blanking plate 14 can block the ductile iron castings. When the ductile iron castings fall on the blanking plate 14, the lifting plate 9 is driven to rise by the electric push rod 8. At the same time, the motor 22 drives the threaded rod 24 to rotate, driving the baffle plate 21 to move away from the bottom of the blanking plate 14, and the ductile iron castings contact the upper end of the support column 20. At this time, if the spherical surface of the ductile iron casting contacts the end of the support column 20, the pressure sensor 32 cannot detect the pressure, and then The plurality of blanking plates 14 are driven to move simultaneously again, so that the adjusting wheel 25 fits the ductile casting, and then the plurality of motors 642 are started in turn, and the plurality of adjusting wheels 25 rotate in turn. Since the adjusting wheel 25 contacts the surface of the ductile casting and has a certain friction force, the ductile casting will roll under the rotation of the adjusting wheel 25, and the four adjusting wheels 25 respectively drive the ductile casting to rotate in different directions. Whenever an adjusting wheel 25 stops rotating, the adjusting wheel 25 is away from the ductile casting. If the pressure sensor 32 still cannot detect the pressure, the adjusting wheel 25 continues to fit the ductile casting and drives it to rotate. The ductile iron casting is moved until the circular through hole of the ductile iron casting faces downward, and the ductile iron casting is sleeved on the support column 20. At the same time, the bottom of the ductile iron casting contacts the pressure sensor 32 on the support block 30. When the pressure sensor 32 detects the pressure, the cylinder 26 drives the threaded sleeve 27 to move upward, and the multiple connecting rods 28 rotate at the same time, and the multiple positioning rods 29 move radially at the same time until the positioning rods 29 contact the inner wall of the circular through hole of the ductile iron casting to fix the ductile iron casting. At this time, the electric push rod 8 is used to drive the ductile iron casting that has been fixed to descend. At the same time, the baffle 21 is reset to block the subsequent ductile iron castings. Then, the motor 2 drives the threaded rod 3 to rotate, so that the frame 4 moves horizontally until the axis of the fixed plate 53 is aligned with the axis of the support column 20, and then the ductile casting is driven to rise again. At the same time, the motor 5 37 drives the threaded rod 4 35 to rotate, the threaded sleeve 2 36 moves upward, and the multiple connecting rods 38 rotate at the same time, driving the multiple radial rods 39 to move radially at the same time until the polishing brush 40 contacts the surface of the ductile casting, and then the motor 4 33 drives the rotating plate 34 to rotate to polish the surface of the ductile casting; After the polishing is completed, the ductile iron casting is removed from the support column 20, and then the above operations are repeated, so that multiple ductile iron castings are successively sleeved on the support column 20 and polished, thereby realizing the automatic feeding of multiple ductile iron castings to be polished, and avoiding the situation that it is difficult for clamping structures such as manipulators to pick up and fix each ductile iron casting one by one because multiple ductile iron castings are randomly stacked together, which in turn affects the subsequent polishing work of the ductile iron casting.

[0030] In this embodiment, as Figures 9-12 shown, a first anti-jamming component is further provided on the blanking plate 14; The first anti-jamming component includes a fourth slide bar 52 fixedly connected to one side of the blanking plate 14. A threaded block 50 is slidably connected to the fourth slide bar 52. One side of the upper end surface of the threaded block 50 is fixedly connected with two third slide bars 47. A push block 41 is slidably connected to the third slide bars 47. The push block 41 can pass through a through hole on one side of the blanking plate 14 and move at the through hole.

[0031] One side of the threaded block 50 is threadedly connected with a fifth threaded rod 51. Both ends of the fifth threaded rod 51 are rotatably arranged on the blanking plate 14. A seventh motor 44 is fixedly connected to one side of the blanking plate 14. The output end of the seventh motor 44 is fixedly connected with one end of the fifth threaded rod 51. A gear 45 and an eccentric block 46 are rotatably arranged on one side of the threaded block 50. The eccentric block 46 is in contact with the bottom of the push block 41. A rack 49 is fixedly connected to one side of the blanking plate 14. The gear 45 meshes with the rack 49. A spring 48 is sleeved on one side of the third slide bar 47. The upper end of the spring 48 is fixedly connected with the push block 41, and the lower end is fixedly connected with the threaded block 50.

[0032] A second anti-jamming component is further provided on the support ring 10; The second anti-jamming component includes a plurality of support rods 18 fixedly connected to the outer circumference of the support ring 10 for one week. A first cylinder 19 is fixedly connected to one side of the support rod 18. The piston end of the first cylinder 19 is fixedly connected with a push plate 43. The push plate 43 is aligned with the middle area of the elastic pad 15.

[0033] Specifically, in the above embodiment, although the automatic feeding of the ductile iron casting can be realized, when multiple ductile iron castings are uniformly placed at the blanking plate 14 and the elastic pad 15, extrusion collisions will occur between the ductile iron castings. Since the funnel-shaped channel is wide at the top and narrow at the bottom, it is easy for the ductile iron castings to be stuck between the blanking plates 14 and unable to fall normally, which affects the subsequent feeding work; Therefore, to solve the above problems, during the use of this embodiment, when the ductile iron casting is added to the blanking plate 14, the seventh motor 44 drives the fifth threaded rod 51 to rotate, causing the threaded block 50 to move horizontally on the fourth slide rod 52. Then, the pushing block 41 moves horizontally at the through hole of the blanking plate 14. At the same time, the gear 45 rotates under the action of the rack 49, and the eccentric block 46 continuously presses the pushing block 41. Meanwhile, in cooperation with the spring 48, the pushing block 41 reciprocates up and down, causing the pushing block 41 to perform a compound motion in the horizontal and vertical directions, multi-directionally pushing the ductile iron casting stuck at the blanking plate 14 to promote the movement of the ductile iron casting. At the same time, the first cylinder 19 drives the push plate 43 to press the elastic pad 15, causing the elastic pad 15 to form a protrusion, and then the ductile iron casting on the elastic pad 15 can be pushed. Thus, by means of the pushing block 41 and the elastic pad 15 pushing the ductile iron casting, the movement of the ductile iron casting in the funnel-shaped channel is promoted, avoiding the situation where the ductile iron casting cannot fall normally due to being stuck between the blanking plates 14, and ensuring the smooth progress of the subsequent feeding work.

[0034] Working principle: Since the blanking plate 14 and the elastic pad 15 cooperate with each other to form a funnel-shaped channel, the adjusting ring 11 can be driven up and down by the motor 2 17 to drive the threaded rod 2 16 to rotate according to the size of the ductile iron casting, and the connecting rod 12 drives the adjustment of the distance between the blanking plate 14 and the axis of the support ring 10. At the same time, the elastic pad 15 will also deform until only one ductile iron casting can pass through the narrowest part of the entire funnel-shaped channel at a time, and the ductile iron castings cannot pass side by side. Then, multiple ductile iron castings are uniformly added to the blanking plate 14, and the ductile iron castings fall under the action of gravity. In addition, the baffle 21 in the initial state fits with the bottom of the blanking plate 14, so the blanking plate 14 can adjust the ductile iron casting. When the ductile casting falls on the blanking plate 14, the lifting plate 9 is driven to rise by the electric push rod 8. At the same time, the motor 3 22 drives the threaded rod 3 24 to rotate, driving the baffle 21 to move away from the bottom of the blanking plate 14, and the ductile casting contacts the upper end of the support column 20. At this time, if the spherical surface of the ductile casting contacts the end of the support column 20, the pressure sensor 32 cannot detect the pressure, and then drive multiple blanking plates 14 to move simultaneously again, so that the adjusting wheel 25 fits the ductile casting, and then multiple motors 6 42 are started in turn, and multiple adjusting wheels 25 rotate in turn. Since the adjusting wheel 25 contacts the surface of the ductile casting and has a certain friction, the ductile casting will roll under the rotation of the adjusting wheel 25. The ductile iron casting is moved, and the four adjusting wheels 25 drive the ductile iron casting to rotate in different directions respectively. Whenever an adjusting wheel 25 stops rotating, the adjusting wheel 25 moves away from the ductile iron casting. If the pressure sensor 32 still cannot detect the pressure, the adjusting wheel 25 continues to fit the ductile iron casting and drives it to rotate until the circular through hole of the ductile iron casting faces downward and the ductile iron casting is sleeved on the support column 20. At the same time, the bottom of the ductile iron casting contacts the pressure sensor 32 on the support block 30. When the pressure sensor 32 detects the pressure, the cylinder 26 drives the threaded sleeve 27 to move upward, the multiple connecting rods 28 rotate at the same time, and the multiple positioning rods 29 move radially at the same time until the positioning rods 29 contact the circular through hole of the ductile iron casting. The inner wall of the hole is contacted to fix the ductile casting. At this time, the electric push rod 8 is used to drive the ductile casting that has been fixed to descend. At the same time, the baffle 21 is reset to block the subsequent ductile casting; then the motor 2 drives the threaded rod 3 to rotate, so that the frame 4 moves horizontally until the axis of the fixed plate 53 is aligned with the axis of the support column 20, and then the ductile casting is driven to rise again. At the same time, the motor 5 37 drives the threaded rod 4 35 to rotate, the threaded sleeve 2 36 moves upward, and the multiple connecting rods 38 rotate at the same time, driving the multiple radial rods 39 to move radially at the same time until the polishing brush 40 contacts the surface of the ductile casting, and then the motor 4 33 drives the rotating plate 34 to rotate to polish the surface of the ductile casting;After the polishing is completed, the ductile iron casting is removed from the support column 20, and then the above operations are repeated, so that multiple ductile iron castings are successively sleeved on the support column 20 and polished, thereby realizing the automatic feeding of multiple ductile iron castings to be polished, and avoiding the situation that it is difficult for clamping structures such as manipulators to pick up and fix each one one by one because multiple ductile iron castings are randomly stacked together, which in turn affects the subsequent polishing work of the ductile iron castings. When the ductile iron casting is added to the blanking plate 14, the motor seven 44 drives the screw rod five 51 to rotate, so that the threaded block 50 moves horizontally on the slide rod four 52, and then the push block 41 moves horizontally at the through hole of the blanking plate 14. At the same time, the gear 45 rotates under the action of the rack 49, and the eccentric block 46 continuously presses the push block 41. At the same time, in cooperation with the spring 48, the push block 41 reciprocates up and down, so that the push block 41 makes a compound movement in the horizontal and vertical directions, and pushes the ductile iron casting stuck at the blanking plate 14 in multiple directions to promote the movement of the ductile iron casting. At the same time, the cylinder one 19 drives the push plate 43 to press the elastic pad 15, so that the elastic pad 15 forms a protrusion, and then the ductile iron casting on the elastic pad 15 can be pushed. Thus, by the way of pushing the ductile iron casting by the push block 41 and the elastic pad 15, the movement of the ductile iron casting in the funnel-shaped channel is promoted, and the situation that the ductile iron casting cannot fall normally because it is stuck between the blanking plates 14 is avoided, ensuring the smooth progress of the subsequent feeding work.;
