Description

Technical Field

[0001] The utility model relates to the technical field of automobile casting production, in particular to a turnover device for a lower cylinder block conveying line. Background Art

[0002] At present, automobile casting products such as automobile engine cylinder heads are all processed from cast or forged blanks. In the casting process, sand cores are often used for casting. After the automobile casting products are cast in the casting mold, they are taken out by a manipulator and conveyed to the sand cleaning process through a conveying line to remove the sand cores in the automobile casting products.

[0003] The automobile engine cylinder head includes an upper cylinder block and a lower cylinder block. After the automobile engine cylinder head completes the sand cleaning process, the upper cylinder block and the lower cylinder block need to be placed on the conveying line for subsequent cleaning, drying and other processes. Since both the upper and lower surfaces of the upper cylinder block and the lower cylinder block need to be cleaned, the upper cylinder block and the lower cylinder block on the conveying line need to be turned over.

[0004] For a conventional lower cylinder block conveying line, a manipulator usually needs to be additionally set up to clamp and turn over the lower cylinder block by using the manipulator. Although the turning-over action can be realized, the structure of the manipulator is complex and the manufacturing cost is high. Moreover, due to the large mass of the lower cylinder block, it is difficult to clamp and turn over, and the manipulator is prone to damage after long-term use. To solve the above problems, some manufacturers have manufactured a drum-type turning-over structure. For example, a cylinder block turning-over machine on a drum line disclosed in Chinese Patent Application No. CN201821190867.8 includes a mounting seat. Both sides of the outer wall of the top of the mounting seat are bolted with support seats, and an arc-shaped chute is provided on the outer wall of the top of the support seat. A turning-over plate with a circular cross-section is slidably connected to the inner wall of the bottom of the chute, and a through hole is provided on the outer wall of one side of the turning-over plate. Four fixing plates distributed in a circular array are bolted between the two through holes, and a plurality of transmission rollers are horizontally and equidistantly arranged between adjacent two fixing plates through bearings. After the internal combustion engine cylinder block is fixed by pushing the pressing plate with a cylinder, it is turned over by using a second motor. The connecting rod and the connecting plate are rotated by using a first motor to rotate the cylinder and the pressing plate on the connecting plate, so that the internal combustion engine cylinder block rotates, and thus it can be adjusted according to actual operation requirements, which is convenient for processing the outer surfaces of the internal combustion engine cylinder block.

[0005] Although the above cylinder block turning-over machine on the drum line can realize turning-over on the line, it requires cylinder drive, the equipment cost is high, and it is impossible to determine whether it has turned in place after rotation, and it is easy to have a material jamming phenomenon during feeding and discharging.

[0006] Therefore, the prior art still needs to be improved and developed. Summary of the Utility Model

[0033] As Figures 1 to 8 , this embodiment discloses a flipping device for a lower cylinder block conveying line, including:

[0034] A base 10, on which a plurality of pulley supports 11 are provided;

[0035] A roller frame 20, rotatably arranged on the pulley support 11, including two annular plates 21. Between the two annular plates 21, a first connecting column 22 and a second connecting column 23 are connected. Kits 24 are fixed to both the first connecting column 22 and the second connecting column 23. After the roller frame 20 rotates 180°, the positions of the two kits 24 are interchanged;

[0036] A resistance limiting mechanism 30, including a cushion seat 31, a spring 32, and a pressing block 33. The cushion seat 31 is fixed on the base 10. The cushion seat 31 is provided with a groove. The spring 32 is arranged in the groove. The pressing block 33 is connected to the upper end of the spring 32. An arc-shaped groove for the kit 24 to be inserted into is provided at the upper end of the pressing block 33;

[0037] A driving device 40, used to drive the roller frame 20 to rotate;

[0038] The conveying mechanism 50 is fixed inside the roller frame 20, has two and is mirror-symmetrical. A channel 51 for the movement of the lower cylinder body 60 is provided between the two conveying mechanisms 50. A positioning column 52 arranged along the conveying direction is further provided on one of the conveying mechanisms 50.

[0039] For the flipping device of the lower cylinder body conveying line in this embodiment, a plurality of pulley supporting members 11 are provided on the base 10, and the roller frame 20 is rotatably arranged on the pulley supporting members 11. Through the support of the pulley supporting members 11, the roller frame 20 can rotate more smoothly; two mirror-symmetrical conveying mechanisms 50 are arranged inside the roller frame 20, and a channel 51 is provided between the two conveying mechanisms 50. After the lower cylinder body 60 enters the channel 51, the driving device 40 is used to drive the roller frame 20 to rotate 180°, so as to realize the flipping of the lower cylinder body 60. Compared with the conventional manipulator, the structure is simpler, the flipping efficiency is higher, and it is not easy to be damaged.

[0040] Moreover, this embodiment also sets a resistance limiting mechanism 30. The resistance limiting mechanism 30 includes a cushion seat 31, a spring 32, and a pressing block 33. Through the supporting action of the spring 32 on the pressing block 33, the pressing block 33 always has an upward supporting force, so that before and after the kit 24 is clamped into the arc-shaped groove at the upper end of the pressing block 33, the rotational resistance of the roller frame 20 will change, so that when the staff manually flips, they can intuitively determine whether the roller frame 20 has rotated to a predetermined angle through the change of the rotational resistance of the roller frame 20.

[0041] For example, it is set that Figure 5 The shown rotation angle is 0°. At this time, the kit 24 corresponding to the second connecting column 23 is clamped into the arc-shaped groove at the upper end of the pressing block 33. Due to the supporting action of the spring 32, the pressing block 33 presses the kit 24 corresponding to the second connecting column 23 upward, and the rotational resistance of the roller frame 20 is increased through the resistance limiting mechanism 30. And this state can be set as the feeding stage of the lower cylinder body 60. When the operator manually flips, through the change of the rotational resistance of the roller frame 20, it can be known that the roller frame 20 has rotated to a predetermined angle, and then the feeding of the lower cylinder body 60 is carried out, which can ensure that the lower cylinder body 60 smoothly enters the channel 51 between the two conveying mechanisms 50.

[0042] When the roller frame 20 is flipped 180°, as Figure 6 shown, the kit 24 corresponding to the first connecting column 22 is clamped into the arc-shaped groove at the upper end of the pressing block 33. Due to the supporting action of the spring 32, the pressing block 33 presses the kit 24 corresponding to the first connecting column 22 upward, and the rotational resistance of the roller frame 20 is increased through the resistance limiting mechanism 30. And this state can be set as the discharging stage of the lower cylinder body 60. Through the change of the rotational resistance of the roller frame 20, it can be known that the roller frame 20 has rotated to a predetermined angle, and then the discharging of the lower cylinder body 60 is carried out, which can ensure that the lower cylinder body 60 smoothly moves out of the channel 51.

[0043] Please refer to Figure 3 , in this embodiment, the pulley support member 11 includes a bottom support 111 and two pulleys 112 provided on the bottom support 111. The annular plate 21 is placed on the two pulleys 112. An annular groove is provided on the outer surface of the pulley 112. The position of the annular plate 21 is restricted by the annular groove of the pulley 112 to avoid the deviation of the annular plate 21 and improve the rotational stability of the drum rack 20.

[0044] Please refer to Figure 3 and Figure 4 , in this embodiment, the conveying mechanism 50 includes two cushion plates 53 fixed to the annular plate 21 and two rows of roller conveying devices 54 fixed on the cushion plates 53. The positioning column 52 is located between the two rows of roller conveying devices 54. The lower end of the lower cylinder body 60 has a laterally penetrating arc-shaped limiting groove. By providing the positioning column 52, when the lower cylinder body 60 enters the channel 51, the positioning column 52 can slide and cooperate along the arc-shaped limiting groove. After the positioning column 52 enters the arc-shaped limiting groove, it can also limit the lower cylinder body 60 to avoid deviation when the lower cylinder body 60 flips, ensuring the smooth progress of the flipping.

[0045] Please refer to Figure 1 and Figure 2 , since a large amount of water will be carried when the lower cylinder body 60 enters the flipping device after cleaning one surface on the conveying line, in order to avoid water remaining in the flipping device, a number of through holes 531 are also provided on the cushion plate 53. A water tank 12 is formed at the upper end of the base 10, and a water guiding pipe is connected to the bottom of the water tank 12. When the lower cylinder body 60 flips, the water on its surface can drip into the water tank 12 along the through holes 531 and then be discharged to other positions through the water guiding pipe.

[0046] Please refer to Figures 5 to 8 , the flipping device further includes a blocking mechanism 70. The blocking mechanism 70 includes a mounting plate 71 provided at one end of one of the cushion plates 53 along the conveying direction. A round hole is provided on the mounting plate 71, and a T-shaped limiting member 72 is inserted through the round hole. The blocking mechanism 70 is provided at the discharging end position of the channel 51. When the rotation angle is 0°, as Figure 6 shown, the T-shaped limiting member 72 hangs on one side of the channel 51 under the action of gravity to block one end of the channel 51 and prevent the lower cylinder body 60 in the channel 51 from sliding out; when the rotation angle is 180°, as Figure 8 shown, the blocking mechanism 70 rotates to the lower part of the channel 51, and the T-shaped limiting member 72 does not block one end of the channel 51, so that the lower cylinder body 60 in the channel 51 can be discharged from this side, with a clever structure.

[0047] Please refer to Figure 5, the driving device 40 includes a driving gear 41, a motor 42 for driving the driving gear 41, a plurality of fixed gears 43 fixed on the annular plate 21, and a chain 44 meshing with the driving gear 41 and the fixed gears 43. The motor 42 drives the driving gear 41 to rotate, and then indirectly drives the annular plate 21 to rotate through the chain 44. The structure is simple and the driving accuracy is high.

[0048] Please refer to Figure 5 , the roller frame 20 further includes a plurality of annular baffles 25 fixed inside the first connecting column 22 and the second connecting column 23 to prevent the lower cylinder block 60 from sliding out radially along the channel 51 during the flipping process.

[0049] The above has specifically described the preferred embodiments of the present invention, but the present invention is not limited to the described embodiments. Those skilled in the art can also make various equivalent variations or substitutions without departing from the spirit of the present invention, and these equivalent variations or substitutions are all included within the scope defined by the claims of the present invention.
