Description

Technical Field

[0001] This utility model relates to the field of laser tube cutting machine technology, and more specifically to a double chuck small tube beveling tube cutting machine. Background Technology

[0002] In existing laser tube cutting equipment, the clamping and rotation of the tube mainly relies on the chuck. Traditional tube cutting machines typically use a single chuck structure or place the drive motor near the main chuck, leading to several problems: Firstly, insufficient space utilization. Placing the drive motor of the front chuck near the main chuck occupies a significant amount of space, resulting in a bulky overall structure that is not conducive to a compact layout. Secondly, there is the risk of interference and collision: when the main chuck moves back and forth, it is prone to colliding with the front chuck, requiring avoidance designs and thus affecting processing efficiency. Furthermore, chuck-based tube cutting equipment cannot effectively cut the tube tail material, leading to waste. For short tail material cutting, manual cutting is often required, increasing labor costs and material waste.

[0003] To address the above problems, an improved double-chuck small-tube beveling cutter is proposed to solve the defects such as insufficient space utilization, inconvenient tail material cutting, and poor cutting stability. Utility Model Content

[0004] In view of this, the present invention provides a double chuck small pipe beveling and cutting machine.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A double-chuck small pipe beveling machine includes a frame on which a main chuck, a front chuck, and a cutting assembly are mounted. The frame is provided with a linear slide rail, on which the main chuck and the front chuck are slidably connected. The front chuck includes a front chuck seat connected to the linear slide rail, a front chuck clamping part above the front chuck seat, and a front chuck drive motor at the bottom of the front chuck capable of driving the front chuck clamping part to rotate. The frame is provided with a front chuck drive cylinder connected to the bottom of the front chuck. The cutting assembly includes a vertically movable cutting bracket and a left-right rotatable cutting head mounted on the cutting bracket.

[0007] In the preferred embodiment, the front clamping part has an internal hollow structure to form a channel for the pipe to pass through, and the front clamping part is provided with multiple clamping claws on the side away from the main chuck.

[0008] In a preferred embodiment, the front card clamping part is provided with a first synchronous gear, the front card drive motor is provided with a second synchronous gear, and a synchronous belt is provided between the front card drive motor and the front card clamping part.

[0009] In a preferred embodiment, the front mounting bracket is provided with an opening for the timing belt to pass through, and a cover that can shield the timing belt is fixed on the front mounting bracket.

[0010] In a preferred embodiment, the front clamping part is provided with a positioning clamping assembly on the side near the main chuck. The positioning clamping assembly includes a clamping cylinder and two clamps that are respectively connected to the cylinder body and the push rod of the clamping cylinder.

[0011] In a preferred embodiment, a material drop plate is provided on the frame below the cutting head. The material drop plate has an inclined structure and covers the linear slide rail and the front clamping drive cylinder.

[0012] In a preferred embodiment, the main chuck includes a main chuck clamping part, a Y-axis drive motor, and a first main chuck drive motor. The frame is provided with a rack that interacts with the Y-axis drive motor, and the main chuck clamping part is provided with a main chuck rotating gear that interacts with the first main chuck drive motor.

[0013] As can be seen from the above technical solution, compared with the prior art, the present invention has the following beneficial technical effects:

[0014] The drive motor of the front chuck is located at the bottom of the front chuck seat and is driven by a synchronous belt. This effectively utilizes the space at the bottom of the equipment, avoids interference with the main chuck, and ensures the compactness of the equipment structure. Both the front chuck drive motor and the synchronous belt are located at the bottom of the front chuck and protected by a cover, effectively preventing dust. The cutting head can rotate left and right, coordinating with the movement and rotation of the pipe held by the main chuck and the front chuck to achieve beveling and short-tail cutting. This eliminates the need for manual secondary cutting of short-tail materials, reduces material waste, and improves production efficiency. In summary, this utility model of a double-chuck small pipe beveling machine, through reasonable structural optimization, not only improves the space utilization and protection effect of the equipment but also achieves stable and efficient pipe cutting, making it particularly suitable for applications requiring beveling and short-tail cutting.

[0026] Please refer to a dual-chuck small-tube beveling and cutting machine. Figure 1-6 The machine includes a frame 100, which serves as the base for the pipe cutting machine. A main chuck 200, a front chuck 300, and a cutting assembly 400 are mounted on the frame 100. A linear slide rail 110 is provided on the frame 100, and the main chuck 200 and the front chuck 300 are slidably connected to the linear slide rail 110. The cutting assembly 400 includes a cutting bracket 410 that can move up and down, and a cutting head 420 that can rotate left and right on the cutting bracket 410. The cutting bracket 410 is connected via a vertical plate on the frame 100, and the two are connected via a slide rail. A drive motor is provided at the top of the cutting bracket 410, and a rotary motor is also provided between the cutting bracket 410 and the cutting head 420 to achieve 45° left and right rotation. The cutting head 420 is a laser cutting head. When cutting pipes, the pipe cutting machine clamps, moves, and rotates the pipe after it is loaded, using the main chuck 200 and the front chuck 300 for cutting. Combined with the left-right rotating cutting head 420, it can achieve short-tail cutting and beveling, improving processing efficiency. Short-tail cutting is not required manually, avoiding waste of materials or manpower. The front chuck 300 includes a front chuck seat 310 connected to the linear slide rail 110. A front clamping part 320 is located above the front chuck seat 310. The front chuck seat 310 has a flat structure, ensuring that the front clamping part 320 can be stably installed on the front chuck seat 310. Multiple sliders connected to the linear slide rail 110 are located at the bottom of the front chuck seat 310, allowing the front chuck seat 310 to slidably connect to the linear slide rail 110. The bottom of the front chuck 300 is equipped with a front chuck drive motor 330 that can drive the front chuck clamping part 320 to rotate, allowing the front chuck clamping part 320 to clamp the pipe and rotate it for the cutting head 420 to cut. The frame 100 is equipped with a front chuck drive cylinder 120 connected to the bottom of the front chuck 300. Both the front chuck drive cylinder 120 and the front chuck drive motor 330 are located below the front chuck seat 310, providing better protection and saving space. Some existing pipe cutting machines with front chucks place the drive motor for rotation near the main chuck, which occupies space. Furthermore, when the main chuck 200 slides close to the front chuck 300, there is a risk of collision, or the main chuck must avoid the front chuck, thus affecting the processing effect. This utility model places the rotation drive motor of the front chuck 300 at the bottom of the front chuck seat 310, which can provide effective protection and make more efficient use of the space below.

[0027] Furthermore, the front clamping part 320 has an internal hollow structure to form a channel for the pipe to pass through. The front clamping part 320 has multiple clamping claws 321 on the side away from the main chuck 200. The front clamping part 320 clamps the pipe through the clamping claws 321. The main chuck 200 has a main clamping part 210 and a first main chuck drive motor 230 that can drive the main clamping part 210 to rotate. The main clamping part 210 has a main chuck rotation gear that cooperates with the first main chuck drive motor 230. The main clamping part 210 and the front clamping part 320 can be controlled to clamp and rotate synchronously through the control system on a typical pipe cutting machine, so as to achieve stable cutting of the pipe and precise cutting positioning. The front card clamping part 320 is provided with a first synchronous gear 322, and the front card drive motor 330 is provided with a second synchronous gear 331. A synchronous belt is provided between the front card drive motor 330 and the front card clamping part 320. The synchronous belt is not shown in the figure. The rotation drive of the main card clamping part 210 is prevented by direct gear drive, while the front card clamping part uses a synchronous belt, which makes it convenient for the front card drive motor 330 to be set at the bottom of the front chuck 300, so as to realize the protection and avoidance of the front card drive motor 330. The front mounting bracket 310 is provided with an opening 311 for the timing belt to pass through. When installing the timing belt, it can be preferentially fitted onto the first timing gear 322. The lower end of the timing belt passes through the opening 311 through the bottom of the front mounting bracket 310 and is fitted onto the second timing gear 331 to achieve connection. A cover 312 that can cover the timing belt is fixed on the front mounting bracket 310. The cover 312 can wrap around the side of the timing belt near the cutting head 420, which can protect the operation of the timing belt from being affected, and at the same time prevent dust from falling onto the timing belt, thereby improving the service life of the timing belt.

[0028] Furthermore, the front clamping part 320 is provided with a positioning clamping assembly on the side near the main chuck 200. The positioning clamping assembly includes a clamping cylinder 313 and two clamps 314 that are respectively connected to the cylinder body and the push rod of the clamping cylinder 313. The two clamps 314 are distributed opposite to each other. The function of the positioning clamping assembly is to clamp the pipe through the positioning clamping assembly when the main chuck 200 moves back and forth, so as to prevent the pipe from moving with it. Since the drive motor of the front chuck 200 is located at the bottom, the positioning clamping assembly can be installed in its side space. Moreover, the positioning clamping assembly occupies less space, and the main chuck 200 does not need to make too much room for it. A material discharge plate 130 is located on the frame 100 below the cutting head 420. The material discharge plate 130 has an inclined structure and covers the linear slide rail 110 and the front clamping drive cylinder 120. The material discharge plate 130 allows the cut pipe to slide directly out of the frame 100 through the inclined structure for easy collection. The position and structure of the material discharge plate 130 can protect the linear slide rail 110 and the front clamping drive cylinder 120, preventing the material discharge from affecting the forward and backward movement of the front chuck 300. The main chuck 200 is equipped with a Y-axis drive motor 220, and the frame 100 is equipped with a rack for the Y-axis drive motor 220. The Y-axis drive motor 220 is equipped with a gear or gear set that matches the rack. The main chuck 200 moves forward and backward through the engagement of the rack. Since the main chuck 200 does not need to save space or avoid obstacles, its drive motor does not need to be located at the bottom.
