Description

Technical Field

[0001] This invention relates to a centralized operation platform for batch flipping processes in the field of mechanical technology, specifically, to a centralized operation device and method for batch assembly of cylinder heads for medium and high-speed diesel engines. Background Technology

[0002] As one of the core components of a medium- and high-speed diesel engine, the cylinder head assembly is complex in structure and diverse in function. It typically includes intake and exhaust valve assemblies, injector assemblies, rocker arm assemblies, as well as key components such as starting valves, indicator valves, and safety valves. These components are precisely arranged inside the cylinder head, working in conjunction with internal structures such as the cooling water chamber, intake chamber, exhaust chamber, and lubrication oil passages to ensure the normal operation of the diesel engine.

[0003] However, in the production process of cylinder head assembly, although the existing process flow (such as spacer installation, sealing test, valve seat installation, intake and exhaust valve installation, indicator valve installation, etc.) has ensured the quality and performance of cylinder head components to a certain extent, there are still many shortcomings and areas that need to be optimized.

[0004] First, the cylinder head assembly process is characterized by "large batches of the same component and repetitive operations." This means that on the production line, workers need to repeatedly perform the same procedures, such as pressing valve seats one by one on the hydraulic press platform and installing valve guide rods on the assembly platform. This repetitive operation not only increases the labor intensity of workers but may also lead to a decrease in production efficiency.

[0005] Secondly, the cylinder head assembly production workstations are located in multiple locations, and the process connections are not seamless. In the existing production process, workers need to frequently move cylinder head components between multiple workstations such as the assembly platform, sealing test bench, and hydraulic press workbench. This not only increases the handling costs during the production process, but may also lead to damage or quality degradation of the cylinder head components due to improper handling during the handling process.

[0006] Furthermore, the cylinder head assembly process requires the cooperation of multiple workers. Due to the loose connection between processes, frequent communication and coordination among workers are necessary to ensure the smooth operation of the production process. This manual cooperation not only increases production costs but may also lead to production delays or quality problems due to poor communication or improper coordination. Summary of the Invention

[0007] To address the aforementioned shortcomings in the prior art, this invention provides a centralized operation platform and method for the batch flipping process of cylinder head assembly in medium- and high-speed diesel engines, enabling batch operation of cylinder head assembly steps and improving the efficiency of the cylinder head assembly process.

[0009] The batch flipping platform includes a support frame, a rotating frame, and a geared motor. The motor drives the rotating frame to flip.

[0012] The cylinder head fixing beam is mounted on the rotating frame and is detachable and adjustable to meet the needs of different cylinder head models; a sealing ring can be configured on the cylinder head fixing beam according to the sealing test requirements.

[0013] The mobile hydraulic press is used for pressing in and installing interference fit parts such as valve seats and guide sleeves. It is used in conjunction with a batch flipping platform. After the flipping platform flips the cylinder heads to a specified angle in batches, the mobile hydraulic press is used to complete the pressing and installation step one by one in batches.

[0014] Preferably, the mobile hydraulic press is an electro-hydraulic type and equipped with casters.

[0015] According to another aspect of the present invention, a method for batch centralized operation of cylinder head assembly for medium- and high-speed diesel engines is provided, comprising:

[0016] The cylinder heads of medium and high speed engines are installed in batches onto the fixed crossbeams of the flipping platform. The sealing test fixtures are configured according to the requirements. The batch flipping operation plan is based on the flipping table, equipped with a water pump base and a mobile hydraulic press.

[0024] Figure 3 The flowchart illustrates a preferred embodiment of the present invention for a batch centralized operation method of cylinder head assembly for medium- and high-speed diesel engines. Detailed Implementation

[0025] The embodiments of the present invention are described in detail below: These embodiments are implemented based on the technical solution of the present invention, and provide detailed implementation methods and specific operation processes. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, and these all fall within the protection scope of the present invention.

[0026] Please see Figure 1 , Figure 1 The figure shows a schematic diagram of the overall structure of a centralized batch assembly device for medium- and high-speed diesel engine cylinder heads, provided as an embodiment of the present invention. It consists of two main parts: a batch tilting platform and a mobile hydraulic press. The batch tilting platform is the core component of the entire device, responsible for tilting the cylinder heads to allow for different assembly processes at multiple angles. Figure 2 As shown, the platform includes key components such as a support frame, a rotating frame, and a geared motor. The support frame is the basic structure of the batch turnover platform, providing stable support and ensuring the safety and stability of the entire turnover process. The rotating frame is mounted on the support frame and can rotate 360° around it. This turnover action is achieved by a geared motor through gear transmission. The geared motor is the power source driving the rotating frame to rotate. It transmits power to the rotating frame through gear transmission, thereby realizing the turnover action. The use of a geared motor ensures a smooth and precise turnover process. The batch turnover platform is made of structural steel, a material with advantages such as high strength, light weight, and corrosion resistance, making it suitable for manufacturing equipment that needs to withstand heavy loads and frequent turnovers.

[0027] The cylinder head fixing beam is a key component mounted on the rotating frame, used to secure the cylinder head and ensure its stability and safety during rotation. The cylinder head fixing beam is detachable and adjustable to accommodate different cylinder head models. Furthermore, sealing rings can be configured on the cylinder head fixing beam according to the requirements of sealing tests. This allows for direct sealing tests after rotation to a specified angle, without the need for additional fixing and sealing steps.

[0028] The mobile hydraulic press is a key piece of equipment used in conjunction with the batch turnover platform. It is mainly used for pressing in and installing interference-fit parts such as valve seats and guide sleeves. The mobile hydraulic press is electro-hydraulic, meaning it uses electricity to drive a hydraulic pump to generate hydraulic power, thereby completing the pressing-in installation. For easy movement and use between different workstations, the mobile hydraulic press is also equipped with casters. Once the batch turnover platform has flipped the cylinder head to the designated angle, the operator can easily move the hydraulic press to the corresponding position for the pressing-in installation operation.

[0029] The mobile hydraulic press is used in conjunction with a batch flipping platform. After the batch flipping platform flips the cylinder heads to a specified angle, the mobile hydraulic press is used to complete the pressing and installation steps one by one.

[0030] like Figure 3 As shown, an embodiment of the present invention provides a method for centralized batch assembly of cylinder heads for medium- and high-speed diesel engines, which allows all cylinder head assembly processes to be completed at the same workstation, thereby greatly improving production efficiency. The specific steps include the following:

[0031] Preparation phase: First, according to the specific requirements of cylinder head assembly, install the corresponding sealing rings on the cylinder head fixing beams. Then, install the cylinder heads in batches onto these cylinder head fixing beams.

[0032] Flipping and Operation: Next, the motor drives the rotating frame to rotate, turning the cylinder head to a suitable angle according to assembly requirements. At this angle, the first sub-assembly process of the cylinder head (such as a sealing test) is completed. After completing this process, the motor drives the rotating frame to rotate to the next suitable angle again for the second sub-assembly process (such as valve seat press-fitting). This process will continue until all cylinder head sub-assembly operations are completed on the batch flipping platform.

[0033] Integration and Optimization: Throughout the entire operation, the batch flipping platform and the mobile hydraulic press work closely together to achieve batch flipping and centralized operation of cylinder heads. This not only solves the problems of scattered workstations and poor process connection in traditional production methods, but also significantly reduces the work of repeatedly transferring and loading / unloading workpieces, thereby greatly improving production efficiency and quality stability.

[0034] The embodiments of the present invention solve the problems of multiple production stations, discontinuous process connections, and the need for multiple workers to cooperate in the assembly of cylinder heads for medium and high-speed diesel engines. It realizes batch operation of cylinder head assembly and reduces repeated work of getting on and off the machine.
