Description

Technical Field

[0001] The invention belongs to the technical field of rudder shaft processing, and in particular relates to a ship shaft processing device and a processing method thereof. Background Art

[0002] The rudder shaft is an important component in ship engineering. It is defined as a fixed shaft that replaces the rudder post and is used by the rudder blade to rotate. The main function of the rudder shaft is to support the rudder blade and allow the rudder blade to rotate around it to control the ship's heading. The rudder shaft is usually located between the steering gear and the rudder blade. It is a key component that connects the steering gear output shaft and the rudder blade, so that the rotational motion of the steering gear can be transmitted to the rudder blade, thereby realizing the steering control of the ship. In the ship's maneuvering equipment, the rudder shaft plays a core role, ensuring that the rudder blade can accurately respond to the steering gear's instructions and rotate accordingly to control the ship's sailing direction.

[0003] The rudder shaft usually needs to be machined with several grooves, such as right-angle grooves, keyways and V-shaped grooves. In the machining of the rudder shaft, the bottom surface of the support seat needs to have a right-angle groove parallel to the axis of the cylindrical shaft. Therefore, the right-angle groove is crucial to ensure the shape and position tolerance of the support shaft and the stability of product quality. The keyway machining is used to fix the key position to ensure machining accuracy. The V-shaped groove helps to more accurately position and clamp the rudder shaft. In the one-end clamping tooling, the groove in the middle of one of the positioning blocks is V-shaped.

[0004] However, since lubricating oil and chips are often present during the machining process, it is not convenient to observe the groove machining status in real time, and thus it is impossible to accurately ensure the groove quality. As a result, errors in groove machining are not discovered until later, which is time-consuming and laborious. Summary of the invention

[0039] Embodiment 1

[0040] like Figure 1-2 As shown, the present invention provides a marine shaft processing device, including a base plate 1, a cover 2 covering the outside of the base plate 1, a cylinder 5 installed on the base plate 1, and a trapezoidal arrangement is formed between the cylinder 5, the rod 1 6 and the rod 2 7. The cylinder 5, the rod 1 6 and the rod 2 7 are connected by a connecting rod 10, and the cylinder 5, the rod 1 6 and the rod 2 7 are all hinged on the connecting rod 10, and the connecting rod 10 is hinged on the base plate 1. At the same time, the hinge point of the connecting rod 10 is arranged on the base plate 1 so that when the rod 1 6 rises, the rod 2 7 falls, and when the rod 1 6 falls, the rod 2 7 rises; the other end of the rod 2 7 is hinged on the upper clamping rod 8, and the other end of the upper clamping rod 8 is hinged on the base plate 1, and the other end of the rod 1 6 is hinged on the lower clamping rod 9, and the other end of the lower clamping rod 9 is hinged on the base plate 1; at the same time, an inlet 4 is provided on the cover 2, and an outlet is provided on the base plate 1 corresponding to the inlet 4; a spray head 3 is provided directly above the inlet 2.

[0041] Furthermore, the hinge point of the connecting rod 10 on the base plate 1 is located between the hinge points of the rod 1 6 and the rod 2 7 on the connecting rod 10 .

[0042] When the cylinder 5 is turned on, the cylinder 5 drives the rod 2 7 to press downward, and drives the rod 1 6 to press upward, so that the upper clamping rod 8 and the lower clamping rod 9 can clamp the workpiece passing through the entrance 4.

[0043] The rudder shaft usually needs to be machined with several grooves, such as right-angle grooves, keyways and V-shaped grooves. In the machining of the rudder shaft, the bottom surface of the support seat needs to have a right-angle groove parallel to the axis of the cylindrical shaft. Therefore, the right-angle groove is crucial to ensure the shape and position tolerance of the support shaft and the stability of product quality. The keyway machining is used to fix the key position to ensure machining accuracy. The V-shaped groove helps to more accurately position and clamp the rudder shaft. In the one-end clamping tooling, the groove in the middle of one of the positioning blocks is V-shaped.

[0044] The cylinder 5 and the sprinkler head 3 are communicatively coupled to the control panel.

[0045] The control panel contains a PLC controller, which can program the numerical control system. The PLC is used as the central control system, and the touch screen is used to realize the program input and operation control of the whole machine, so as to realize the full automation of the transportation process. The control system can be used as a system that connects various actuators to move according to the logical trajectory, and the actuators can be controlled by programming to run according to the required operation steps.

[0046] Based on the above device, the first embodiment of the present invention also proposes a processing method using the above-mentioned marine shaft processing device, comprising the following steps:

[0047] Step 1: The workpiece to be processed is clamped by the robot and sent to the entrance 2, and then passes through the exit;

[0048] Step 2, the cylinder 5 is turned on, the upper sizing 8 and the lower clamping rod 9 clamp the workpiece, and the lathe performs groove processing on the workpiece. At this time, the chips are blocked outside the entire device by the bottom plate 1, thereby preventing the chips from affecting the workpiece;

[0049] Step 3: At this time, the workpiece has chips and lubricating oil. In order to better observe the groove processing state, the cylinder 5 is started again, the workpiece is released, the manipulator retracts, and the processed part of the workpiece is retracted into the cover 2;

[0050] Step 4: Turn on the spray head 3, and the spray head 3 sprays the workpiece after processing. The bottom plate 1 and the cover 2 are both made of acrylic board, so that the staff can better observe the processing status of the workpiece. At the same time, a water outlet is provided at the bottom of the cover 2, so that the sewage after spraying is discharged from the water outlet to avoid the sewage affecting the subsequent processing and polluting the workshop environment;

[0051] In step 5, the robot sends the workpiece out of the outlet again, processes the next groove on the workpiece, and repeats steps 2 to 4 until the processing is completed.

[0052] The device can process a plurality of grooves on the rudder shaft, and the whole process is automated. At the same time, it is convenient for the staff to observe the processing status at any time, and it can avoid the influence of the operation process on the subsequent processing to the greatest extent.

[0056] The cleaning device includes a bracket 11, a mobile frame 12 movably mounted on the bracket 11 through a lifting assembly 13, a fixed base 14 movably mounted on the mobile frame 12 through a rotating cylinder, and two fixed frames 15 symmetrically hinged on the fixed base 14. At the same time, the fixed frames 15 are movably mounted on the fixed base 14 through a telescopic cylinder 23. When the telescopic cylinder 23 is turned on, the telescopic cylinder 23 drives the fixed frame 15 to rotate around the hinge point on the fixed base 14; a fixed plate 17 is movably mounted on the fixed frame 15 through an electric guide rail 22, a roller brush 18 is movably mounted on the fixed plate 17 on one side through a motor 21, and a spray gun 24 is mounted on the fixed plate 17 on the other side through a support frame 28.

[0059] Due to the design of the telescopic cylinder 23, it is easy to align the capillary head 29 with various places of the groove, thereby ensuring complete flushing of each groove;

[0060] Furthermore, the capillary head 29 can be replaced manually by the brush head 16. When there is no need for flushing with clean water, such as after drying, the brush head 16 can be replaced to clean the groove or processing position.

[0061] The rotary cylinder, the lifting assembly 13, the motor 21, the telescopic cylinder 23, the electric guide rail 22, the spray gun 24, the cylinder 5 and the spray head 3 are communicatively coupled to the control panel.

[0062] Based on the above device, the first embodiment of the present invention also proposes a processing method using the above-mentioned marine shaft processing device, comprising the following steps:

[0063] Step 1: The workpiece to be processed is clamped by the robot and sent to the entrance 2, and then passes through the exit;

[0064] Step 2, the cylinder 5 is turned on, the upper sizing 8 and the lower clamping rod 9 clamp the workpiece, and the lathe performs groove processing on the workpiece;

[0065] Step 3, start the cylinder 5 again, release the workpiece, retract the manipulator, and retract the processed part of the workpiece into the cover 2;

[0066] Step 4: Turn on the spray head 3 to spray the workpiece.

[0067] Step 5: The robot sends the workpiece out of the outlet again, processes the next groove on the workpiece, and repeats steps 2 to 4 until the processing is completed;

[0068] Step 6: After the groove processing is completed, the workpiece is sent to the cleaning device;

[0069] Step 7: First, the spray gun 24 completely cleans the grooves of the workpiece, especially the corners and other places where dirt is easy to hide; the spray gun 24 can clean the grooves in detail to avoid omissions, and the cleaning position is adjusted by turning on the electric guide rail 22 and the telescopic cylinder 23 during the operation;

[0070] Step 8: After the detailed cleaning is completed, the rotary cylinder is turned on to transfer the roller brush 18 to the workpiece;

[0071] Step nine, shower and scrub;
