Description
Technical Field
[0001] This utility model relates to the field of cylinder head technology, specifically a high-efficiency polishing 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 cap. The smoothness of its surface directly affects the working quality of the valve mechanism and the cylinder. Although manufacturers perform surface leveling on the cylinder head during processing, this leveling process only achieves flatness and cannot address the underlying issues. The undulations and grooves on the cylinder head surface result in numerous imperfections, such as dents and scratches. While these may meet basic usage requirements, they severely impact the user experience. Traditional solutions tend to fix the cylinder head in place and then precisely process the dents and scratches like a CNC machine tool. This approach inevitably leads to low efficiency, and excessively high precision is unnecessary in practical applications. Given this situation, how to ensure efficient processing of dents and scratches on the cylinder head surface has become an increasingly urgent problem for relevant technical personnel.

[0011] The beneficial effects of this utility model's high-efficiency polishing equipment for processing cylinder heads are as follows:
[0012] 1. The track, which is limited by the positioning plate and retracts inward and backward, provides a good structural basis for the continuous tumbling of the cylinder head on the track surface. The design of the vent holes and their diameter gradually decreasing from the outside to the inside provides a good structural basis for the preservation of the stainless steel balls, which act as abrasives, inside the track. The limiting plate's limitation ensures that the contact of the inner surface of the middle of the track provides a good structural basis for the stainless steel balls to be squeezed outward. The cylinder head and stainless steel balls mix and tumble, and the cylinder head surface can be fully polished in a short time, that is, all bumps and scratches are removed. The combination of large quantity in one go and short time effectively ensures the efficient treatment of bumps and scratches on the cylinder head surface.
[0013] 2. In addition to being kept inside the track and squeezed upwards as much as possible, stainless steel balls may still be squeezed downwards. The push plate provides a good structural basis for pushing the stainless steel balls into the storage basket, the reel provides a good structural basis for lifting the storage basket, and the cylinder provides a good structural basis for tilting the storage basket and adding the stainless steel balls to the upper part of the track. This effectively ensures the full utilization of the stainless steel balls and the polishing effect. Attached Figure Description

[0028] The working principle of this utility model's high-efficiency polishing equipment for processing cylinder heads is as follows: Open cabinet door 2, place the cylinder head to be polished in the inward position of track 16, then close cabinet door 2. Start the first motor 22, the second motor 5, and the third motor 18 in sequence. The output shaft of the first motor 22 drives the lower wheel 4 to rotate, thereby causing track 16 and the upper wheel 20 to rotate synchronously. The upper part of track 16 moves upward, and with the assistance of the protrusion 25, the cylinder head tumbles. The upper and lower parts of the inward position of track 16 come into contact, forcing stainless steel balls outward through the perforation 26. This includes upward and downward extrusion. The upwardly extruded stainless steel balls mix and tumble with the cylinder head. During tumbling, the cylinder head surface is thoroughly polished through seamless contact. Because the stainless steel balls have a small diameter, even bumps, scratches, and imperfections in hard-to-reach areas such as grooves and holes can be cleaned. The downwardly extruded stainless steel balls require… The stainless steel balls are collected and added to the upper part of the track 16 to continue polishing. The output shaft of the second motor 5 drives the screw 8 to rotate. Under the sliding limit of the slide bar, the moving plate 7 and the push plate 24 move backward synchronously, pushing the scattered stainless steel balls into the storage basket 11. The output shaft of the third motor 18 drives the reel 19 to rotate. The reel 19 winds up the hanging rope 13 until the storage basket 11 is raised above the upper wheel 20. The output end of the cylinder 17 extends and flips the storage basket 11 forward and upward. The stainless steel balls in the storage basket 11 are then added to the upper part of the track 16 to continue polishing. The stainless steel balls are thus sufficient to ensure the polishing quality. After the time is up, the output shaft of the first motor 22 stops rotating, and the stainless steel balls fall back into the space between the left upright plate 21, the right upright plate 28, the upper wheel 20, the lower wheel 4, and the track 16 through the drain hole 26. The cabinet door 2 is opened and the cylinder head is taken out, thus completing one work cycle.
[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.
