Description
Technical Field
[0001] This utility model relates to the field of cylinder head technology, specifically a high-efficiency leveling device for processing cylinder heads. Background Technology
[0002] The cylinder is a core component of an engine, mainly consisting of the cylinder barrel, cylinder head, piston, piston rod, and sealing rings. The vast automotive market today creates a huge demand for cylinders and their components. To ensure the overall performance of the cylinder, all parts must be manufactured according to specified standards. Taking the cylinder head as an example, it serves as both the mounting base for the valve mechanism and the cylinder's sealing cover. The smoothness of its surface directly affects the normal operation of the valve mechanism and the cylinder as a whole. Therefore, during cylinder head processing, leveling equipment is needed to level its surface. The main leveling method involves placing the cylinder head flat on a workbench and then using a pressure block to directly press down on the cylinder head surface to keep the overall flatness error within a controllable range. However, the design of traditional leveling equipment remains relatively primitive; loading, unloading, and pressing down all require manual intervention, resulting in limited leveling efficiency. Given this situation, how to improve the leveling efficiency of cylinder heads has become an increasingly urgent problem for relevant technical personnel. Summary of the Invention

[0028] The working principle of this utility model of a high-efficiency leveling device for processing cylinder heads is as follows: Cylinder heads to be leveled are sequentially placed at the upper end of the feeding channel 1. Under the action of gravity, the cylinder heads slide along the inclined section of the feeding channel 1 into the horizontal section, and are then blocked by the front end of the right limiting baffle 25, stopping between the front end of the left limiting baffle 24 and the right limiting baffle 25. The output end of the lower cylinder 6 pushes the push rod 29, connecting plate 33, guide rod 30, vertical push plate 16, and horizontal push plate 32 as a whole to move backward. The sliding connection between rod 29, guide rod 30, horizontal push plate 32, and vertical plate 17 keeps the backward movement of horizontal push plate 32 stable. Combined with the limiting positions of left and right limit plates 24 and 25, the cylinder head moves stably backward on the feeding platform 5, causing the output end of the lower cylinder 6 to cycle repeatedly. This extends the cylinder heads lined up on the surface of the feeding platform 5 to the surface of the middle loading platform 26 near the central hole 27. The output end of the lower cylinder 6 then pushes the horizontal push plate 32 backward again, and the horizontal push plate 32 moves the cylinder head at the rearmost position... The cylinder head is pushed into the central hole 27, with the lower part of the cylinder head located inside the central hole 27 and the edge located on the central platform 26 so as not to fall into the central hole 27. The output end of the upper cylinder 11 pushes the lifting plate 13 to move vertically downward along the outer guide post 12 until the spring around the inner guide post 21 is fully compressed. At this time, the pressure block 20 is tightly pressed against the cylinder head. This pressing process can flatten the surface of the cylinder head, so that the overall plane error is kept within a controllable range. The output end of the upper cylinder 11 is reset, and the output end of the inner cylinder 35 pushes the inner push post 36 upward until the flattened cylinder head is pushed out. The compressed air in the air pump 9 is sprayed out instantaneously along the guide tube 18, blowing the cylinder head on the surface of the inner push post 36 directly into the discharge channel 3. A bucket is placed below the discharge channel 3, and the cylinder head slides into the bucket along the discharge channel 3, thus completing one working cycle. During this process, the lower infrared detector 2 detects whether the cylinder head is in place on the central platform 26, and the upper infrared detector 19 detects whether the pressure block 20 is pressed down in place.
[0029] The above are merely specific embodiments of this utility model, but the protection scope of this utility model is not limited thereto. Any changes or substitutions conceived without inventive effort should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope defined in the claims.
