Description

Technical Field

[0001] The utility model relates to the technical field of processing tooling, in particular to a processing tooling for paired flanges of marine four-stroke diesel engine pipelines. Background Art

[0002] As the core power source of a ship, the performance of a marine diesel engine directly impacts its safety and operational efficiency. Among the many components of a marine diesel engine, flanges play a crucial role. Flanges not only connect various pipelines, ensuring the flow of media like fuel, gas, and cooling water, but also provide sealing. Therefore, flange machining accuracy is crucial to the overall performance of the diesel engine.

[0003] However, the flanges used in marine diesel engines come in many different types, shapes, sizes, and thicknesses. In traditional machining processes, due to the complex structure of the flanges, interference often occurs, making it impossible to complete the machining of the flanges in a single clamping, requiring multiple clampings. This not only increases the difficulty of machining and prolongs the machining time, but may also lead to a decrease in the machining accuracy of the flanges, thereby affecting the airtightness and overall performance of the diesel engine. In addition, multiple clampings are prone to cumulative errors, further reducing the machining quality of the flanges. In summary, the existing methods have the problems of frequent interference, multiple clampings, and low machining accuracy during flange machining. Utility Model Content

DETAILED DESCRIPTION

[0027] The following describes embodiments of the present invention in more detail with reference to the accompanying drawings. Although certain embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be construed as being limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the present invention. It should be understood that the accompanying drawings and embodiments of the present invention are for illustrative purposes only and are not intended to limit the scope of protection of the present invention.

[0028] The following describes some embodiments of the present invention in detail with reference to the accompanying drawings. The following embodiments and features thereof may be combined with one another unless they conflict with each other. Furthermore, the sequence of steps in the following method embodiments is provided for illustrative purposes only and is not intended to be a strict limitation.

[0029] Marine four-stroke diesel engines are core components of a ship's power system, and their performance directly impacts the vessel's operational stability and safety. Among the many key components of a diesel engine, the quality and machining accuracy of its pipe flanges are particularly crucial. These flanges not only connect pipelines, ensuring the efficient flow of media like fuel, gas, and cooling water, but also must ensure a tight seal under high pressure and high temperature. However, the diverse range of flanges used in marine diesel engines, with complex shapes, varying sizes, and thicknesses, leads to frequent interference during traditional machining.

[0030] Due to the diversity and complexity of flange structures, traditional machining methods often require multiple clamping of the workpiece to complete each machined surface. This not only increases machining time but also easily leads to cumulative errors, making it difficult to ensure flange machining accuracy. Furthermore, multiple clamping processes increase the difficulty of moving and positioning the workpiece during machining, further reducing production efficiency and even affecting the quality of the final product.

[0031] In view of the above problems, the utility model provides a processing tool for the matching flanges of marine four-stroke diesel engine pipelines, which is used to avoid interference, reduce the number of clamping times, and improve processing accuracy and efficiency during the flange processing.

[0032] Figure 1 The present invention provides a schematic diagram of a structural tooling for a marine four-stroke diesel engine pipeline matching flange. Figure 1 As shown, the processing tooling includes a base 1, a clamp assembly 2, a limiting assembly 3 and a moving assembly.

[0033] In this embodiment, the machining tool consists of a base 1, a fixture assembly 2, a limit assembly 3, and a moving assembly. These four components together constitute the core structure of the flange machining tool. Specifically, the base 1 is the foundation of the entire device, used to support and secure the other components. The fixture assembly 2 is used to clamp the flange workpiece, the limit assembly 3 is used to limit the position and movement of the workpiece, and the moving assembly is used to control the movement of the fixture assembly 2, thereby achieving precise positioning of the flange.

[0034] A movable slot 4 is defined in the center of the base 1, with the fixture assembly 2 and the position-limiting assembly 3 positioned above the base 1. In this embodiment, the movable slot 4 in the center of the base 1 allows the fixture assembly 2 to move freely along the slot, thereby enabling precise positioning of the flange. Both the position-limiting assembly 3 and the fixture assembly 2 are mounted above the base 1, ensuring the overall compactness and ease of operation of the fixture.

[0035] In an optional embodiment, the movable chute 4 can be designed as a straight line or an arc according to the shape and size of the flange. A ball guide or precision bearing can be added to the inside of the chute to reduce friction and improve the smoothness of movement.

[0036] The limit assembly 3 is fixed to one end of the movable chute 4; the clamp assembly 2 is positioned above the movable chute 4, with the clamp assembly 2 and the movable chute 4 configured for sliding connection. In this embodiment, the limit assembly 3 is mounted at one end of the movable chute 4 to ensure that the clamp assembly 2 has sufficient range of movement. The clamp assembly 2 engages the chute through a sliding connection, allowing it to slide freely and adapt to flanges of different sizes.

[0037] The moving assembly is provided with a moving screw 5 and a handle 6. A limiting bolt hole 7 is provided in the middle of the limiting assembly 3 to match the moving screw 5. The moving screw 5 is inserted into the limiting bolt hole 7. One end of the moving screw 5 is fixedly connected to the clamp assembly 2, and the other end is fixedly connected to the handle 6. In this embodiment, the moving assembly controls the movement of the clamp assembly 2 through the moving screw 5 and the handle 6. A threaded hole is provided in the middle of the limiting assembly 3 to match the moving screw 5. The moving screw 5 passes through the threaded hole, one end is fixedly connected to the clamp assembly 2, and the other end is connected to the handle 6 for manual adjustment of the position of the clamp assembly 2.

[0038] In an alternative embodiment, the movable screw 5 can be a precision ball screw to improve transmission stability and positioning accuracy. The handle 6 can be designed with an ergonomic shape to ensure comfortable operation. The position and size of the threaded hole can be adjusted according to the requirements of the specific workpiece.

[0039] Figure 2 This is a schematic diagram of the structure of a clamp assembly 2 provided in an embodiment of the present utility model. Figure 2 As shown, the clamp assembly 2 is a stepped structure, and an anti-slip pad 8 is fixed to one side of the clamp assembly 2 , and an anti-slip groove 9 is provided on the anti-slip pad 8 .

[0040] In this embodiment, the clamp assembly 2 adopts a stepped structure to better clamp flanges of different thicknesses. An anti-skid pad 8 is installed on one side of the clamp, and an anti-skid groove 9 is provided on the anti-skid pad 8 to prevent the flange from sliding during processing.

[0041] In an alternative embodiment, the stepped fixture can be configured to accommodate flanges of varying sizes by varying step heights and widths. The anti-slip pad 8 can be made of a high-friction material (such as rubber or polyurethane), and the anti-slip grooves 9 can be arranged in various patterns (such as a cross-grid or parallel lines) to further enhance the clamping force. Furthermore, the anti-slip pad 8 can be configured as a removable structure for quick replacement after wear, extending the tooling's service life.

[0042] The sliding connection of the fixture assembly 2 can be achieved by T-slots and T-blocks to ensure the stability and accuracy of the sliding. A locking device can also be added to the sliding connection to fix the fixture assembly 2 after the workpiece is positioned.

[0043] In an optional embodiment, the moving assembly is further provided with a moving slider 10 .

[0044] Figure 3 This is a schematic diagram of the structure of a movable slider 10 provided in an embodiment of the present utility model. Figures 1 to 3 As shown, the movable slider 10 is a T-shaped structure.

[0045] A limiting slide groove 11 adapted to the moving slider 10 is opened in the moving slide groove 4, and the moving slider 10 and the limiting slide groove 11 are configured to be movably connected; a first through hole 12 is opened in the middle of the clamp assembly 2, and a first fixing bolt 13 is passed through the first through hole 12; the lower end of the first fixing bolt 13 is threadedly fixedly connected to the upper end of the moving slider 10.

[0046] In this embodiment, the connection between the movable slider 10 and the limiting slide groove 11 is designed to be a movable connection, which allows the clamp assembly 2 to slide more smoothly and reduces the possibility of friction and jamming.

[0047] Optionally, the T-shaped design of the movable slider 10 provides excellent stability and anti-overturning resistance. The limiting slide 11 can be a linear guide to reduce sliding friction and improve precision. To increase sliding smoothness, the slider surface can be coated with a low-friction coating or manufactured from a self-lubricating material, further improving the tooling's service life and operational performance.

[0048] A first through hole 12 is formed in the middle of the clamp assembly 2, through which a first fixing bolt 13 passes and is threadedly connected to the upper end of the movable slider 10. Through the above structure, the clamp assembly 2 can be firmly fixed to the movable slider 10 and can be adjusted in position as the movable slider 10 moves.

[0049] Optionally, the first fixing bolt 13 can be made of a high-strength material to withstand a greater clamping force. The through-hole can be designed as an elliptical or elongated shape to allow fine-tuning of the clamp assembly 2 within a certain range, increasing adjustment flexibility. The threaded portion of the fixing bolt can be coated with a locking coating or equipped with a locking washer to prevent loosening under vibration or frequent operation.

[0050] Figure 4 This is a schematic diagram of the structure of a limit assembly 3 provided in an embodiment of the present utility model. Figure 4 and Figure 1 As shown, second through holes 14 are formed at both ends of the limiting assembly 3 , and second fixing bolts 15 are passed through the two second through holes 14 ; the lower ends of the second fixing bolts 15 are fixedly connected to the base 1 by threads.

[0051] In this embodiment, the two ends of the limit assembly 3 are respectively provided with second through holes 14, and the second fixing bolts 15 pass through the through holes and are threadedly connected to the base 1. This structure can ensure the stability of the limit assembly 3 during the processing process and will not be offset due to vibration or movement.

[0052] Optionally, the second fixing bolt 15 can be configured as a quick-detachable structure to facilitate quick adjustment of the position of the stop assembly 3. The location and number of the second through holes 14 can be designed based on actual processing requirements to accommodate different flange types. The fixing bolt can be made of a corrosion-resistant material, such as stainless steel or galvanized steel, to ensure long-term use in various environments.

[0053] In an optional embodiment, the limiting assembly 3 can be fixed at a specified position of the base 1 by bolts, or quickly fixed and released using a locking mechanism.

[0054] Figure 5 This is a schematic diagram of the structure of a base 1 provided in an embodiment of the present utility model. Figure 5 and Figure 1As shown, third through holes 16 are formed at both ends of the movable slide 4, and third fixing bolts 17 are passed through the two third through holes 16; the lower ends of the third fixing bolts 17 are threadedly connected to the fixing device.

[0055] In this embodiment, the above structure allows for additional fixation of the base 1 to enhance the stability and durability of the base 1, especially when the workpiece is heavy or requires high-precision processing, to ensure that the base 1 is fixed and will not loosen or shift due to vibration during processing.

[0056] Optionally, the third fixing bolt 17 can be configured as a bolt with an anti-loosening function, such as using a bolt with a nylon anti-loosening washer, or adopting a double nut design to prevent loosening. The third through hole 16 can be designed as an elongated slot to allow a certain adjustment margin, which is convenient for adjusting the fixed position of the movable slide 4 when needed. The fixing device can be a pre-set screw hole on the processing table or a movable fixing bracket, so that it can be flexibly adjusted according to specific processing requirements. To further enhance the stability of the system, a locking washer or anti-vibration material can be added at the connection between the fixing device and the bolt.

[0057] Figure 6 This is a schematic diagram of the structure of a mobile component provided by an embodiment of the present utility model. Figure 6 As shown, the moving assembly is further provided with a screw stepping motor 18 and a distance sensor 19 adapted to the moving screw.

[0058] In this embodiment, the moving screw 5 is passed through the screw stepper motor 18; the distance sensor 19 is arranged on one side of the limit assembly 3, and the distance sensor 19 is configured to monitor the distance between the limit assembly 3 and the clamp assembly 2; the screw stepper motor 18 is fixed on the motor fixing seat 20, and the motor fixing seat 20 is arranged at one end of the base 1.

[0059] The automation and precision of the tooling can be further enhanced by the screw stepper motor 18 and distance sensor 19. The screw stepper motor 18, coupled with the movable screw 5, enables automated and precise movement control. The distance sensor 19 monitors the distance between the limit assembly 3 and the fixture assembly 2 in real time, ensuring precise position control during machining.

[0060] Optionally, the mounting bracket of the screw stepper motor 18 can be designed as an adjustable structure to accommodate different workpiece processing requirements. The distance sensor 19 can be connected to a data processing unit to implement automated feedback control. When abnormal distance changes are detected, the processing process can be automatically stopped or adjusted to avoid processing errors. Combined with a graphical operating interface, the operator can monitor and adjust processing parameters in real time to optimize the processing process. In addition, a multi-sensor system can be set up to achieve multi-dimensional distance monitoring, further improving the reliability and accuracy of processing.

[0061] In actual application, the processing tool is also provided with a wireless control device, and the distance sensor 19 and the screw stepping motor 18 are both wirelessly connected to the wireless control device.

[0062] Optionally, the screw stepper motor 18 can be equipped with a precision control system and combined with a CNC device to achieve a highly automated flange machining process. The stepper motor's control accuracy can reach micron levels, meeting high-precision machining requirements. The distance sensor 19 can be a laser or ultrasonic sensor to ensure measurement accuracy.

[0063] Wireless control devices can integrate Bluetooth, Wi-Fi, or other wireless communication modules, allowing operators to remotely control and adjust parameters via mobile devices such as tablets or smartphones. Combined with cloud computing technology, processing data can also be uploaded to the cloud for real-time analysis and optimization. Furthermore, the system can be pre-set with multiple processing modes, allowing users to switch between them with a single click via the wireless device, greatly improving the system's flexibility and applicability. To ensure the security of wireless control, encrypted communication protocols can be introduced to prevent unauthorized access and manipulation.

[0064] Wireless control devices can include PLC (Programmable Logic Controller) or CNC (Computer Numerical Control) systems. Combined with PLC or CNC systems, they enable remote control and data logging, further improving machining efficiency and quality. Furthermore, adaptive control systems can be integrated to adjust machining parameters in real time based on flange changes during machining.

[0065] In the embodiment of the present invention, the flange can be clamped and fixed by two symmetrically arranged processing tools, thereby ensuring the position stability and accuracy of the flange during the processing. Specifically:

[0066] The two processing tools are symmetrically arranged on the processing platform, facing each other, to form a complete processing space. This symmetrical arrangement ensures that the force applied by the clamp assemblies 2 of the two tools to the flange during the processing is evenly distributed, thereby preventing the flange from being deformed or displaced due to uneven force.

[0067] The flange to be processed is placed between the two clamp assemblies 2 and is firmly clamped by the anti-slip pads 8 and anti-slip grooves 9 in the clamp assemblies 2. At this time, the function of the limit assembly 3 is to ensure that the clamp assemblies 2 maintain the correct position of the flange during the movement and prevent it from shifting due to sliding.

[0068] The relative position of the clamp assembly 2 is adjusted using the movable screw 5 in the movable assembly. The movable screw 5 is driven by the handle 6 or the screw stepper motor 18, causing the clamp assembly 2 to slide precisely along the movable groove 4 on the base 1. By adjusting the control parameters of the screw stepper motor 18, the position of the clamp assembly 2 can be precisely controlled, thereby adjusting the clamping state of the flange.

[0069] After the flange is clamped, distance sensor 19 monitors the distance between the stop assembly 3 and the clamp assembly 2 in real time. This distance represents the flange's clamping spacing. The sensor's monitoring data is transmitted to the control system via a wireless control device. If the distance detected by the sensor changes beyond the set tolerance range, the system issues an alarm or automatically adjusts the position of the clamp assembly 2 to ensure flange stability during processing.

[0070] Once the flange is securely fixed and the clamp assembly 2 is positioned correctly, the flange can be machined. During machining, the two tooling pieces work together to maintain the flange's balance and position through symmetrical clamping forces, allowing the machining equipment to perform high-precision cutting, drilling, or other machining operations on the flange.

[0071] Throughout the entire machining process, operators can monitor and adjust the status of the machining tooling in real time via wireless control devices. Combined with a PLC or CNC system, operators can dynamically adjust the clamping force and position of the fixture assembly 2 based on the specific flange size and machining requirements during machining, thereby achieving the optimal machining effect.
