Description

Technical Field

[0001] The invention relates to the technical field of engine cylinder block anti-rust spraying, in particular to an electrostatic anti-rust spraying device for an engine cylinder block and a cylinder head. Background Art

[0002] The engine block and cylinder head are very critical components of the internal combustion engine. The cylinder block is the main structural part of the engine, mainly used to accommodate the piston, crankshaft and cylinder. It provides the working space inside the engine and bears the pressure from combustion. The cylinder head is located on the top of the cylinder block, closing the cylinder and providing a closed environment for the combustion chamber. It also accommodates the intake and exhaust valves, ignition devices and other components. The cylinder block and cylinder head are usually made of cast iron or aluminum alloy. In the production process of the internal combustion engine, in order to prevent the cylinder block and cylinder head from rusting during storage and use, a layer of powder coating is usually sprayed with electrostatic anti-rust. The outer side of the engine block has an irregular surface with obvious pits and protrusions, resulting in an uneven overall appearance. On parts with complex shapes, the powder coating may have insufficient adhesion, causing the coating to slip or peel off, affecting product quality, and the spraying spacing needs to be adjusted. Secondly, the engine block and cylinder head lack an appropriate synchronization system during the anti-rust spraying process, resulting in discontinuity in the production process, affecting the overall production arrangement and production efficiency. In response to the above problems, the inventor proposes an electrostatic anti-rust spraying device for engine blocks and cylinder heads to solve the above problems. Summary of the invention

[0051] Working principle: First, the engine cylinder block and cylinder head are transported to the roller conveyor assembly 7 through the external conveying device, and then Figure 2 As shown, the motor 808 is controlled to be turned on, and the motor 808 drives the half gear 802 to rotate counterclockwise through the driving shaft 801. The half gear 802 rotates counterclockwise and first meshes with the first transmission gear 804. The half gear 802 drives the first driven shaft 803 to rotate clockwise for three circles through the first transmission gear 804. Figure 8 As shown, the first driven shaft 803 drives the transmission shaft 703 to rotate counterclockwise for three circles through the fifth bevel gear 706 and the sixth bevel gear 707, and the transmission shaft 703 drives the corresponding conveying rollers 702 to rotate clockwise for three circles synchronously through multiple sets of third bevel gears 704 and fourth bevel gears 705, and the engine cylinder block and cylinder head are conveyed to the spraying position by the rotation of the conveying rollers 702, as shown in FIG. Figure 3 As shown, the screw type lifting device 902 is controlled to be opened, and the lifting plate 2 is driven to rise under the guidance of the lifting guide rail 901 by the screw type lifting device 902, so that the positioning guide rod 405 is flush with the middle of the engine cylinder body, as shown in FIG. Figure 4 As shown, the electric cylinder 605 is controlled to be turned on, and the driving end of the electric cylinder 605 pushes the sliding plate 603 to move under the guidance of the sliding rod 602. The sliding plate 603 drives the two sliding frames 3 to approach each other through the connecting rods 604 on both sides, and the two sets of positioning guide rods 405 are respectively in contact with the two sides of the engine cylinder body. At this time, due to the obvious pits and protrusions on the outer wall of the cylinder body, as shown in FIG. Figure 7 As shown, under the action of the sliding positioning frame 404, the positioning guide rod 405 and the return spring 406, the rectangular block 403 is slidably adjusted in the positioning fixing frame 401, and the steel ball 407 is filled according to the unevenness of the outer wall of the engine cylinder body. The threaded bolt 408 is manually rotated, and the threaded bolt 408 moves to squeeze the rectangular block 403 to position the rectangular block 403. During the adjustment process of the sliding positioning frame 404, as shown in FIG. Figure 6As shown, the sliding positioning frame 404 drives the corresponding moving frame 410 to move under the guidance of the first guide rail 409, and the moving frame 410 drives the corresponding electrostatic spray gun 10 to move synchronously under the guidance of the transverse rod 510 through the moving plate 511. After the spacing of the electrostatic spray gun 10 is adjusted, the driving end of the electric cylinder 605 is controlled to retract, and the two sliding frames 3 are driven to reset according to the reverse steps above, and the screw-type lifting device 902 is controlled to drive the lifting plate 2 to reset. At this time, the electrostatic spray gun 10 is located below the cylinder body, as shown in FIG. Figure 2 As shown, the driving shaft 801 drives the half gear 802 to continue rotating and separates from the first transmission gear 804 and then meshes with the second transmission gear 806. The half gear 802 drives the second driven shaft 805 to rotate one circle through the second transmission gear 806. The second driven shaft 805 drives the left rotating shaft 807 to rotate through the synchronous wheel transmission group. The left rotating shaft 807 drives the right rotating shaft 807 to rotate through the synchronous wheel transmission group. Figure 3 As shown, the two rotating shafts 807 respectively drive the rotating shaft 502 to rotate through the corresponding No. 1 bevel gear 508 and No. 2 bevel gear 509, and the rotating shaft 502 drives the lifting frame 506 to lift and reciprocate once under the guidance of the guide rod 505 through the rotating rod 503 and the guide groove 507. The lifting and lowering movement of the lifting frame 506 drives the electrostatic spray gun 10 to lift and reciprocate to spray the outer wall of the cylinder body. After the spraying is completed, the threaded bolt 408 is manually rotated in the opposite direction, and the positioning guide rod 405 is reset under the action of the reset spring 406.
