Description

Technical Field

[0001] The utility model relates to the field of ring saw technology, specifically a fully automatic hydraulic cutting ring saw. Background Technology

[0002] In the field of industrial cutting, traditional ring saw equipment generally suffers from problems such as low automation, insufficient cutting accuracy, and poor adaptability to working conditions, making it difficult to meet the needs of modern complex processing scenarios. Specifically:

[0003] 1. Dependence on manual operation and efficiency bottlenecks

[0004] Most existing cutting equipment requires manual adjustment of the cutting angle, depth, and movement trajectory. This is especially true when dealing with complex structures such as inclined planes and curved surfaces, which necessitates repeated adjustments, is time-consuming and labor-intensive, and results in significant errors. For example, in shipbuilding or building demolition scenarios, manual adjustment of the cutting posture may account for more than 40% of the total operation time, leading to low efficiency. Furthermore, manual operation in high-risk environments (such as high altitudes and high-temperature areas) poses safety hazards.

[0005] 2. Limited adaptability to various operating conditions and poor equipment versatility.

[0006] Most existing automated cutting equipment is single-axis or dual-axis controlled (capable only of lateral movement or simple oscillation), and cannot achieve multi-angle linkage. For example, when dealing with complex structures such as curved ship hulls and beveled pipes, it is necessary to frequently change equipment or adjust the installation position, and even customize special fixtures. The lack of equipment versatility limits its application in diverse scenarios. Utility Model Content

[0007] The purpose of this utility model is to provide a fully automatic hydraulic cutting ring saw to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, the utility model provides the following technical solution: a fully automatic hydraulic ring saw, comprising a ring saw body, an automatic monorail, a connecting frame, a rotary reducer, and an upper connecting head. One end of the upper connecting head is connected to the rotary reducer, and the other end is used to connect to the body of an external mechanical device. The connecting frame is connected to the output end of the rotary reducer. The automatic monorail is fixedly installed at the bottom of the connecting frame. The ring saw body is installed on the automatic monorail and can reciprocate along the automatic monorail. A swing cutting depth mechanism is also installed on the automatic monorail. The swing cutting depth mechanism is connected to the ring saw body and controls the ring saw to swing in the cutting depth plane.

[0009] Preferably, the automatic monorail includes a crossbeam, with legs fixed at the bottom of both ends of the crossbeam, a rack installed on the top of the crossbeam, a movable frame sleeved on the crossbeam, and a movable motor installed on the movable frame. The movable motor drives the gear set and the rack to mesh to realize the movement of the movable frame.

[0010] Preferably, the oscillating cutting depth mechanism includes a mounting frame, which is fixed to the bottom of the movable frame. A cutting depth motor is fixed on one side of the mounting frame, and a ring saw body is provided on the other side. The cutting depth motor drives the cutting depth plane of the ring saw body to oscillate.

[0011] Preferably, the body of the ring saw is fixed to a connecting plate, the connecting plate is rotatably connected to the mounting frame, a driven wheel is fixed on the side of the connecting plate near the mounting frame, and a driving wheel that meshes with the driven wheel is fixed to the drive end of the cutting depth motor.

[0012] Preferably, the connecting frame is bow-shaped, with connectors at both ends, which are fixed to both ends of the crossbeam, and a mounting plate for connecting to the output end of the rotary reducer is provided on the top of the connecting frame.

[0013] Preferably, the upper connector includes a frame, on which a swing cylinder is mounted. The body of the rotary reducer is rotatably connected to the telescopic end of the swing cylinder and the frame, respectively. The cylinder body of the swing cylinder is fixed to an external machine.

[0014] Preferably, the ring saw body is a hydraulic ring saw, and the hydraulic valves controlling the ring saw body, swing cylinder, moving motor, cutting depth motor and rotary reducer are installed inside the frame. The output end of the rotary reducer is connected to a rotary joint, which serves as the oil circuit connector for each motor.

[0015] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0016] 1. The utility model of fully automatic hydraulic cutting ring saw significantly improves industrial cutting efficiency through automated control and structural innovation: the linkage between the swing cylinder and the reducer allows the cutting saw to swing ±45° and rotate 360°, and the angle adjustment can be completed with one click and the "positioning-cutting depth-cross cutting" process can be executed automatically, reducing the risk and cost of manual operation.

[0017] 2. The equipment can flexibly adapt to various structures such as vertical, inclined, and arc surfaces for cutting. The modular design supports quick assembly and disassembly to adapt to different mechanical carriers, improving efficiency compared to traditional manual equipment. It breaks through the single movement limitation of similar automated equipment and realizes complex curved surface cutting.

[0018] 3. The gear rack and gear transmission accuracy reaches within 0.5mm, and the cutting depth can be finely adjusted in 0.1mm increments. Combined with the stable torque of the hydraulic drive, it ensures cutting accuracy and tool life. Attached Figure Description

[0026] The technical solutions of the utility model embodiments will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the utility model embodiments, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the utility model.

[0027] refer to Figure 1 and Figure 2 The overall structure of the equipment is as follows: This fully automatic hydraulic ring saw mainly consists of the ring saw body 1, automatic monorail 2, oscillating cutting depth mechanism 3, connecting frame 4, rotary reducer 5, and upper connector 6. Each component works collaboratively through mechanical connection and hydraulic control.

[0028] like Figure 5 The structure of the upper connector 6 and the rotary reducer 5 is as follows: The frame 61 serves as the basic support structure and is connected to an external machine (such as a robotic arm, fixed bracket, etc.) through the swing cylinder 62. The cylinder body of the swing cylinder 62 is fixed to the external machine, and the telescopic end is rotatably connected to the body of the rotary reducer 5, which can drive the rotary reducer 5 to swing ±45° in the vertical plane.

[0029] The output end of the rotary reducer 5 is fixedly connected to the connecting frame 4 via the mounting plate 42, enabling the connecting frame 4 and the overall cutting mechanism to rotate 360°.

[0030] The ring saw body 1 is hydraulically driven, achieving high-speed rotary cutting through hydraulic power. Hydraulic valves are integrated inside the frame 61 and control the hydraulic power of the ring saw body 1, swing cylinder 62, moving motor 25, depth-of-cut motor 32, and rotary reducer 5. The hydraulic circuits of these motors are connected to the rotary joint 51, which is installed at the output end of the rotary reducer 5.

[0031] refer to Figure 6 The structure of the connecting frame 4 is as follows: The connecting frame 4 is in the shape of an arc, and both ends are fixed to the two ends of the crossbeam 21 of the automatic monorail 2 through the connecting head 41. The top mounting plate 42 is connected to the output end of the rotary reducer 5 to form a "universal joint" type connection structure, which can transmit rotational and swinging power.

[0032] refer to Figure 3 The automatic monorail 2 has the following structure: The automatic monorail 2 includes a crossbeam 21, with both ends of the crossbeam 21 fixed to the bottom of the connecting frame 4. Support legs 22 are fixed to the bottom positions of both ends of the crossbeam 21. During operation, the support legs 22 support the cutting surface, providing support. A rack 23 is installed on the top of the crossbeam 21, and a sliding movable frame 24 is fitted onto it. A moving motor 25 is mounted on the movable frame 24, and its driven gear set meshes with the rack 23. Through the gear and rack 23 transmission, the movable frame 24 moves left and right along the crossbeam 21, i.e., moves in the sawing direction.

[0033] refer to Figure 3 and Figure 4 The connection relationship between the oscillating cutting depth mechanism 3 and the ring saw body 1 is as follows:

[0034] The oscillating cutting depth mechanism 3 includes a mounting frame 31, a cutting depth motor 32, a connecting plate 34, a drive wheel 33, and a driven wheel 35. The mounting frame 31 is fixed to the bottom of the movable frame 24. The cutting depth motor 32 is mounted on one side, and the other side is connected to the ring saw body 1 via the connecting plate 34. The connecting plate 34 is rotatably connected to the mounting frame 31, and the driven wheel 35 is fixed on the side of the connecting plate 34 closest to the mounting frame 31, meshing with the drive wheel 33 at the drive end of the cutting depth motor 32. The cutting depth motor 32 drives the connecting plate 34 and the ring saw body 1 to oscillate within the cutting depth plane through gear transmission, achieving precise control of the cutting depth.

[0035] Workflow and control logic:

[0036] The equipment's operation is divided into two stages: posture adjustment and automatic cutting. Full automation is achieved through coordinated hydraulic and motor control.

[0037] I. Posture Adjustment Phase

[0038] Swing cylinder 62 control: The swing cylinder 62 is driven to extend and retract through the hydraulic system, which drives the reducer 52 and the connecting frame 4 to swing ±45°, adjusts the tilt angle of the ring saw body 1, and makes the support leg 22 fit with the surface to be cut.

[0039] Rotary joint 53 control: Reducer 52 drives rotary joint 53 to rotate, which in turn drives connecting frame 4 and automatic monorail 2 to rotate 360° as a whole, adjusting the horizontal direction of ring saw body 1 so that it is aligned with the cutting path.

[0040] II. Automatic Cutting Stage

[0041] After pressing the automatic button, each mechanism executes its actions in the following sequence:

[0042] 1) Ring saw start-up: The hydraulic system drives the working motor of the ring saw body 1 to start, and the ring saw rotates at high speed to enter the cutting preparation state.

[0043] 2) Depth of cut control:

[0044] The cutting depth motor 32 drives the drive wheel 33 to rotate, which in turn drives the driven wheel 35 and the connecting plate 34 to swing downward through gear transmission, causing the ring saw body 1 to swing downward in the cutting depth plane and gradually cut into the workpiece to the preset depth.

[0045] The depth of cut angle is precisely controlled by the gear ratio between the driven wheel 35 and the driving wheel 33 and the motor speed.

[0046] 3) Horizontal cutting:

[0047] Once the cutting depth is reached, the moving motor 25 drives the gear set to mesh with the rack 23, causing the moving frame 24 to move left and right along the crossbeam 21, allowing the ring saw body 1 to feed laterally along the cutting path and complete the continuous cutting operation. The moving speed is adjusted by the motor speed and the gear-rack 23 transmission ratio to ensure smooth and efficient cutting.

[0048] Although embodiments of the utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the utility model, the scope of which is defined by the appended claims and their equivalents.
