Description

Technical Field

[0001] This utility model relates to an automatic dust removal device for engine cylinder head air passages, belonging to the field of engine assembly and adjustment technology. Background Technology

[0002] In the automotive manufacturing industry, the assembly process of the engine cylinder head is crucial, and the cleanliness of the air passages directly affects the engine's performance and reliability. Currently, engine cylinder head air passages are commonly cleaned manually using a dust gun. While this method is simple and easy to implement, it has revealed a series of problems and potential risks in practical applications.

[0003] Firstly, controlling the airflow is a challenge when manually cleaning the cylinder head intake manifold with a dust gun. Due to the lack of a precise airflow adjustment mechanism, the airflow during operation is often difficult to control accurately. This results in two problems: on the one hand, excessive airflow makes it difficult to collect flying debris, potentially causing injury to the operator; on the other hand, insufficient airflow leads to incomplete cleaning of the cylinder head intake manifold, posing a risk of foreign objects getting trapped between the cylinder head seat and valves, which could potentially cause engine quality problems.

[0004] Secondly, existing dust removal methods lack relatively stable dust removal time and airflow control. This not only leads to unnecessary energy waste and increases the assembly cost of a single engine, but also makes it difficult to effectively control the efficiency and quality of the entire cleaning process.

[0005] Furthermore, manual dust removal is relatively inefficient and poses certain safety hazards. Factors such as the physical exertion and distraction of operators can affect the cleaning effect, further complicating quality control.

[0006] In summary, existing dust removal methods for engine cylinder head intake ports have significant problems in terms of operating costs, installation efficiency, quality control, and energy consumption, and urgently require a more efficient, safe, and energy-saving dust removal solution to replace them.

[0017] The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the protection scope of this utility model.

[0018] An automatic dust removal device for engine cylinder head air passages includes a sealing seat 6, a sealing base 7, a dual-cylinder cylinder 8, a fixed bracket 11, and a compressed air pipe 12. The upper end of the fixed bracket 11 is fixedly connected to the cylinder body of the horizontally arranged dual-cylinder cylinder 8. The piston rod of the dual-cylinder cylinder 8 is fixedly connected to the sealing base 7. The sealing base 7 is fixed with the sealing seat 6, which has multiple cylinder head air passage nylon-shaped sealing plugs. Each sealing plug is matched and plugged into a corresponding cylinder head air passage. Each sealing plug has a compressed air pipe 12 in its center, and each compressed air pipe 12 is connected to a corresponding cylinder head air passage. The dual-cylinder cylinder 8 and each compressed air pipe 12 are controlled by corresponding solenoid valves. Figure 3 In this system, solenoid valve 3 is a solenoid valve for controlling the air output of cylinders 1-2, solenoid valve 4 is a solenoid valve for controlling the air output of cylinders 3-4, and solenoid valve 5 is a solenoid valve for controlling a dual-column cylinder. The compressed air pipe 12 has a diameter of 12mm, and a matching 10mm / 8mm / 6mm quick-connect fitting connects the dual-column cylinder and the solenoid valve. To prevent incomplete cleaning of the air ducts due to insufficient airflow, each air duct is supplied with an independent air source to enhance cleaning intensity. Each solenoid valve is connected to the PLC circuit board 2 for signal transmission, and the PLC circuit board 2 is controlled to open and close via a power switch 1.

[0019] The power switch 1, PLC circuit board 2, and each solenoid valve are all installed in the wiring box to isolate and protect the electrical components and prevent electric shock.

[0020] The lower end of the fixed bracket 11 is equipped with a lifting platform and a sensor 9. The sensor 9 is used to sense the position of the lifting platform. The lifting platform is equipped with a sensor 10, which is used to sense the position of the pallet. Both the sensor 9 and the sensor 10 are connected to the PLC circuit board 2 for signal transmission. To prevent the equipment from working in a loop, the equipment will only start working when both the sensor 9 and the sensor 10 meet the conditions simultaneously.

[0021] When using this invention, the tray with the cylinder head enters the interior of the invention. The tray is lifted by the lifting platform. Sensor 2 (10) senses that the cylinder head tray has risen to its correct position and transmits a signal to PLC circuit board 2. When the lower part of the lifting platform is fully raised to its correct position, sensor 1 (9) transmits a signal to PLC circuit board 2. The PLC controls the corresponding solenoid valve to activate the double-column cylinder 8, aligning the sealing seat 6 with the corresponding air passage of the cylinder head for sealing. Then, the PLC controls the corresponding solenoid valve to activate and blow air through the cylinder head air passage for cleaning. The cleaning time is set to 13 seconds. After 13 seconds, all solenoid valves close, the double-column cylinder 8 returns to its original position, the tray descends, and the cylinder head is released to the next workstation.

[0022] This invention is not connected to the power supply of the electrical distribution cabinet of the beater equipment or other electronic components, and does not work when there is no engine cylinder head or empty tray passing through the equipment.

[0023] During engine assembly and adjustment, when the engine cylinder head enters the working area, the sensor detects a signal and controls this utility model to replace the traditional manual cleaning operation with a dust gun, automatically completing the engine cylinder head air passage cleaning process. Compared with manual cleaning, it provides more comprehensive air passage cleaning, consistent airflow control time, and higher work efficiency. This utility model has a simple structure and low manufacturing cost. The mechanical structure can be changed according to different working areas, and the control program can be modified as needed. It solves the problems of high cost, low efficiency, and potential quality hazards in the manual cleaning of engine cylinder head air passages with dust guns.

[0024] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of the equivalents of the claims be included within this invention.
