Description

Technical Field

[0001] The utility model relates to the technical field of cylinder head cleaning, in particular to a cylinder head water cavity cleaning tool. Background Art

[0002] The cylinder head is one of the most important parts in a diesel engine, containing structures such as the intake duct, exhaust duct, and cooling water chamber. Due to the external shape of the cylinder head parts and the intake and exhaust ducts, the cooling water chamber has an irregular cross-section and complex shape. In some locations, narrow cross-section channels exist, which directly leads to the localized smallness of the cooling water chamber sand core used in the blank casting. Due to the characteristics of casting production, the production of cooling water chamber sand cores with complex shapes and large cross-sectional variations is difficult. The small cross-section leads to loose sand during the production process, resulting in localized sand sticking and seams in the water chamber during the casting of the cylinder head casting. Therefore, the sticking sand, seams and other debris in the cylinder head water chamber need to be cleaned to ensure the cleanliness of the cavity.

[0003] During the process of cleaning sticky sand or seams in the water cavity of the cylinder head, due to the complex structure of the water cavity, conventional cleaning tools cannot be used in the tortuous water cavity. Due to the limited contact area of ​​the cleaning end, the cleaning efficiency is low and the operator's labor intensity is high.

[0004] During the cleaning process, to check the cleaning effect, the cleaning tool is usually removed from the cylinder head cleaning hole, and then an endoscope is inserted through the cleaning hole. The endoscope camera reaches the cleaning position to determine whether the cleaning is thorough. Due to the complex structure of the cleaning cavity, this method may cause the cleaning position of the tool to be inconsistent with the endoscope inspection position, resulting in an inability to accurately determine the cleaning effect, or a long inspection time and low inspection efficiency. If re-cleaning is required after the inspection, the endoscope needs to be removed and the cleaning tool inserted into the cylinder head again to make the cleaning tool reach the cleaning position again for cleaning, resulting in low cleaning efficiency. Summary of the Invention

[0005] The technical problem to be solved by the present invention is to overcome the existing defects and provide a cylinder head water cavity cleaning tool, which can quickly clean sand inclusions, seams and other debris in the cylinder head cooling water cavity, improve the cylinder head water cavity cleaning efficiency and reduce the labor intensity of the operator, and can effectively solve the problems in the background technology.

[0017] Figure 1 This is a schematic structural diagram of the utility model.

[0018] In the figure: 1 handheld part, 2 hollow flexible shaft, 3 cleaning part. DETAILED DESCRIPTION

[0019] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0020] See also Figure 1, the utility model provides a technical solution: a cylinder head water cavity cleaning tool, comprising a handheld part 1, a hollow flexible shaft 2 and a cleaning part 3;

[0021] The handheld portion 1 is a circular steel tube, which is convenient for holding during cleaning. One end of the handheld portion 1 is connected to the hollow flexible shaft 2, and the handheld portion 1 is connected to the interior of the hollow flexible shaft 2;

[0022] The hollow flexible shaft 2 is made of elastic material, and the cleaning portion 3 is a steel wire, which is evenly wound around the outer side of the hollow flexible shaft 2 .

[0023] The length of the handheld part 1 can be selected according to the needs of the cleaning personnel, and the general length is 80 to 100 mm. The effective length of the cleaning part 3 can be selected according to the length from the sand cleaning port to the cleaning position in the water cavity. The diameter of the cleaning part cannot be too large and should match the cross-sectional size of the water cavity. The cross-section of the hollow flexible shaft 2 is 1 / 3 to 1 / 2 of the minimum cross-section of the cleaning position.

[0024] In order to facilitate the connection between the handheld part 1 and the hollow flexible shaft 2, the outer diameter of the hollow flexible shaft 2 is 1 to 2 mm smaller than the inner diameter of the handheld part 1. The hollow flexible shaft 2 is inserted into the handheld part 1, and the connection between the two is connected by a clamp or by extrusion deformation.

[0025] During use, the cleaning portion 3 bends and deforms with the changing shape of the water cavity, making it easier to clean debris from complex water cavities. The tool can be operated manually by holding the handheld portion 1, or it can be attached to a pneumatic or electric tool, further improving the efficiency of cleaning debris from the water cavity.

[0026] In addition, in order to check the cleaning effect, the cleaning tool does not need to be moved or pulled out. The camera of the endoscope can be passed through the hollow part of the handheld part 1 and the hollow flexible shaft 2 to directly see the cleaning effect of the cleaning position, effectively avoiding the situation where the endoscope is difficult to find the cleaning position; if cleaning is required again, the endoscope can be taken out and the tool can be used to clean it again directly, which reduces the time for the cleaning tool to find the cleaning position and improves the cleaning efficiency.

[0027] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
