Description

Technical Field

[0001] The invention belongs to the field of casting production, and in particular relates to a drainage device used for casting production. Background Art

[0002] In the prior art, the outer ring castings of the bearings need to be rust-proofed after being machine-processed and polished. Currently, the method is mainly to manually dip the outer ring castings in anti-rust water, and then put the outer ring castings of the bearings into a collection frame for unified collection. Then, the collection frame is tilted and rotated by a drainage device, so that the outer ring castings of the bearings in the collection frame are constantly turned over to drain out the anti-rust water remaining on the outer ring castings of the bearings. Since a large amount of iron filings remain on the outer ring castings of the bearings after being machine-processed and polished, the iron filings are not cleaned when the anti-rust water is manually applied, and the residual iron filings affect the subsequent processing. After being dipped in the anti-rust water, the castings need to be collected and transferred to the drainage device, and the outer ring castings of the bearings after drainage are in a disorderly manner, and need to be manually coded for subsequent automated processing. The whole process is cumbersome, time-consuming and labor-intensive.

[0043] In this embodiment, a non-slip rubber strip is provided on one side of the arc block 416 facing the center of the rotating ring 413 .

[0044] The limiting unit at the bottom includes a first limiting rod 420, a second limiting rod 421, a brush rod 422, a first flat gear 423 and a second flat gear 424; the inner bottom surface of the lower annular cover 404 is rotatably connected to the first limiting rod 420; the inner bottom surface of the lower annular cover 404 is rotatably connected to the second limiting rod 421, and the second limiting rod 421 is located on the outside of the first limiting rod 420; the inner bottom surface of the lower annular cover 404 is rotatably connected to two mutually symmetrical brush rods 422, and the second limiting rod 421 is located between the two brush rods 422; the middle part of the second limiting rod 421 is fixedly connected to the first flat gear 423; the lower part of the two brush rods 422 is each fixedly connected to a second flat gear 424; the two second flat gears 424 are both meshed with the first flat gear 423.

[0045] The lower guide unit includes a support roller 425 and a fixed block 426; two mutually symmetrical fixed blocks 426 are fixedly connected to the inner bottom surface of the lower annular cover 404; the support roller 425 is rotatably connected in the two fixed blocks 426.

[0046] During operation, firstly, the air cylinder 201 on the left is controlled to extend to push the electric clamp 202 to move downward, so that the electric clamp 202 clamps the cylinder 406, and then the electric clamp 202 contracts and resets, so that the upper annular cover 404 is separated from the lower annular cover 404, and the limit block 403 is pulled out from the limit frame 401, and then the bearing outer ring 001 processed by the machine tool is placed into the lower annular cover 404 through the existing loading equipment. At this time, the bottom surface of the bearing outer ring 001 contacts with the support roller 425, the inner ring surface of the bearing outer ring 001 contacts with the first limit rod 420 close to the inner ring surface of the annular cover 404, and the outer ring surface of the bearing outer ring 001 contacts with the first limit rod 420 close to the outer ring surface of the annular cover 404, and then the bearing outer ring 001 is limited by the two first limit rods 420;

[0047] Then the cylinder 201 extends to push the electric clamp 202 downward, so that the limit block 403 is inserted into the limit frame 401, so that the two annular covers 404 contact each other, the two gear rings 414 merge, and the electric clamp 202 releases the cylinder 406. Then the drive motor 301 is controlled to start. Based on the view from top to bottom, the output shaft of the drive motor 301 rotates clockwise, thereby causing the fixed plate 302 to drive the second fixed rod 303, the torsion spring shaft 304, the third fixed rod 305 and the cleaning rod 306. The clean drain assembly makes a circular motion. When the third fixing rod 305 rotates and passes through the inverted V-shaped bending portion of the limiting ring 103, the third fixing rod 305 is squeezed by the limiting ring 103 with increasing force, so that the third fixing rod 305 rotates with the torsion spring shaft 304 as the axis, causing the torsion spring shaft 304 to twist. At the same time, the third fixing rod 305 drives the clean drain assembly to move, so that the clean drain assembly and the bearing outer ring 001 therein are immersed in the rust-proof water in the water storage ring 2;

[0048] Then, the anti-rust water contacts the outer ring 001 of the bearing in the annular cover 404, and infiltrates the outer ring 001 of the bearing. As the fixed plate 302 continues to rotate, the cleaning and draining assembly moves in a circular motion along with the second fixed rod 303, so that the two gear rings 414 are meshed with the gear teeth on the ring 6, and then the gear ring 414 drives the rotating ring 413 to rotate, and the rotating ring 413 drives the elastic expansion plate 415, the arc block 416 and the round rod 417 to make a circular motion. When the round rod 417 When the round rod 417 moves past the convex piece 419 on the second fixed ring 418, the round rod 417 is squeezed, so that the elastic expansion plate 415 is stretched, so that the arc block 416 and the bearing outer ring 001 contact each other and squeeze the bearing outer ring 001, thereby driving the bearing outer ring 001 to slide circumferentially in the annular cover 404 through the arc block 416. When the bearing outer ring 001 slides circumferentially in the annular cover 404, it drives the support roller 425 to rotate in the fixed block 426, and at the same time drives the second The limiting rod 421 rotates in the annular cover 404, and the rotation of the second limiting rod 421 drives the first flat gear 423 to drive the second flat gear 424 to rotate, and the second flat gear 424 drives the brush rod 422 to rotate, and the bristles on the brush rod 422 clean the outer ring surface of the bearing outer ring 001, and at the same time, the second cleaning bristles 003 on the annular cover 404 clean the inner ring surface of the bearing outer ring 001, and the third cleaning bristles 004 on the annular cover 404 clean the upper and lower sides of the bearing outer ring 001, so as to clean up the iron filings adhering to the bearing outer ring 001. When the round rod 417 passes through the convex piece 419, the arc block 416 no longer squeezes the bearing outer ring 001, so as to no longer drive the bearing outer ring 001 to slide circumferentially, and then when the rotating ring 413 rotates, the outer ring surface of the bearing outer ring 001 is cleaned by the first cleaning bristles 002, and at the same time, it is ensured that all positions of the bearing outer ring 001 are fully in contact with the anti-rust water in the water storage ring 2;

[0049] The rotating ring 413 rotates and drives the connecting frame 410 to drive the rotating sleeve 409 to rotate. The rotating sleeve 409 drives the fan blades 411 to rotate. The suction force generated by the rotation of the fan blades 411 in the rust-proof water in the water storage ring 2 causes the rust-proof water in the water storage ring 2 to be continuously sucked into the annular cover 404, so that the iron filings cleaned off the bearing outer ring 001 are discharged to the outside of the annular cover 404 in time.

[0050] When the cleaning and draining assembly moves with the second fixing rod 303 to an inverted V-shaped bending portion above or below the limiting ring 103, the torsion spring shaft 304 releases the elastic force to cause the second fixing rod 303 to rotate in the opposite direction and reset, thereby causing the second fixing rod 303 to drive the cleaning and draining assembly to reset, so that the cleaning and draining assembly and the bearing outer ring 001 therein are separated from the rust-proof water in the water storage ring 2. Since the water storage ring 2 is divided into four areas by four mesh plates 3, the iron filings in the rust-proof water are isolated by the mesh plates 3, so that the bearing outer ring 001 passes through the subsequent two When the area is infiltrated, the anti-rust water remains clean and the cleaning effect during infiltration is improved to prevent the iron filings that have been cleaned from adhering to the bearing outer ring 001 again. As the fixed disk 302 continues to rotate, the bearing outer ring 001 in the cleaning and draining assembly will be infiltrated and cleaned for the second time to ensure that the bearing outer ring 001 is fully infiltrated with the anti-rust water and the bearing outer ring 001 is fully cleaned. When the bearing outer ring 001 moves to the bottom of the electric clamp 202 in front with the cleaning and draining assembly, the immersion The bearing outer ring 001 that has been wetted and cleaned is kept separated from the anti-rust water in the annular cover 404, and the anti-rust water remaining on the bearing outer ring 001 is drained. At the same time, the cylinder 201 on the left is extended. The working principle is the same as when it starts working. Another bearing outer ring 001 is placed in another cleaning and draining component through the existing feeding equipment, and is ready for wetting and cleaning. During this process, the cleaning and draining component and the bearing outer ring 001 that has been wetted and cleaned are in a paused state to continue draining. The bearing outer ring 001 After the residual anti-rust water is drained, the front cylinder 201 extends to push the electric clamp 202 downward, and the electric clamp 202 clamps the cylinder 406, and the cylinder 201 shrinks and resets to separate the upper annular cover 404 from the lower annular cover 404, and then the bearing outer ring 001 that has been soaked and cleaned is taken out and collected uniformly through the existing material taking equipment, and then the cylinder 201 extends again to merge the two annular covers 404 again, and this cycle is repeated to realize automatic and uninterrupted soaking and cleaning of the bearing outer ring 001 without manual operation;

[0051] While the bearing outer ring 001 is being soaked, an external anti-rust water circulation filtering device is connected through the outlet pipe 4 and the inlet pipe 5, the anti-rust water with iron filings is pumped out through the outlet pipe 4, and the filtered anti-rust water is introduced into the water storage ring 2 through the inlet pipe 5, so that the anti-rust water in the water storage ring 2 always maintains a certain clean state to avoid excessive accumulation of iron filings in the rust-proof water. At the same time, the anti-rust water leaked from the bearing outer ring 001 is collected and reused to avoid waste of anti-rust water.

[0052] Those skilled in the art should understand that the above embodiments do not limit the present invention in any form, and any technical solutions obtained by equivalent replacement or equivalent transformation shall fall within the protection scope of the present invention.
