Detailed Implementation

[0019] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0021] In the aerospace industry, all composite flexible hoses are laid on steel pipe molds, with a certain amount of allowance at both ends. After the product has cured and set, it needs to be removed from the mold and the allowance cut off. See also Figure 1 As shown, Figure 1 This is a schematic diagram showing the structure of the composite flexible hose before and after cutting on a steel pipe mold in the prior art. In the prior art, the excess portion of the composite flexible hose on the mold 100 needs to be manually cut. For example... Figure 1 The image on the left shows the composite flexible tube 200 before cutting. Figure 1 The image on the right shows a 200mm composite flexible hose after cutting. The manual cutting method described above suffers from problems such as uneven cuts, low efficiency, and inconsistent length tolerance control. The market urgently needs a high-efficiency cutting device for aviation flexible hoses.

[0022] To address the aforementioned issues, this utility model provides a composite flexible tube cutting device that significantly improves production efficiency, has a stable and reliable structure, reduces reliance on operator skills, and ensures stable processing quality.

[0023] The following is combined Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0024] Example 1: See Figures 1-6 As shown, the composite hose cutting device provided by this utility model includes a turntable 1, a base 2, a locking mechanism 3, and a cutting assembly 4. The turntable 1 is located on the base 2 and is rotatable about its own axis. The locking mechanism 3 is located on the turntable 1 and is used to clamp or release the mold 100. The cutting assembly 4 is located on the base 2 and is movable in the horizontal direction. The cutting assembly 4 includes a cutting blade 41. When the cutting blade 41 abuts against the composite hose 200 of the mold 100, it can cut the target position of the composite hose 200.

[0025] The base 2 serves as the platform for the entire machine, the turntable 1 is used to support and drive the workpiece to rotate, the locking mechanism 3 is used to clamp the workpiece, and the position of the cutting component 4 is adjustable to perform the cutting operation.

[0026] Specifically, base 2 provides stable support for the entire device. To ensure stability during the cutting process, base 2 can be made of a material with sufficient weight and rigidity, such as cast iron or a welded structure of thick-walled steel plates. Anti-slip pads can be provided on the bottom of base 2 to ensure the device is placed stably on the worktable.

[0027] In one embodiment of this application, for ease of handling and movement, see [link to relevant documentation]. Figure 2 The base 2 also has a handle integrally formed or fixed by bolts on its side wall or upper part.

[0028] The turntable 1 is horizontally positioned above the base 2 and forms a rotatable connection with it. It is understood that this rotatable connection can employ various established mechanical structures. For example, a short, upward-facing shaft can be positioned at the center of the base 2, and the central bore of the turntable 1 can be mounted on this short shaft via one or more sets of bearings, such as deep groove ball bearings or angular contact bearings, allowing the turntable 1 to rotate smoothly and with low resistance around its central axis. See also... Figure 5 As shown, in this embodiment, a rotating shaft 21 is provided at the center of the base 2, and the rotating shaft 21 is rotatably connected to the base 2 via a bearing.

[0029] Turntable 1 is used to hold the composite flexible hose 200 workpiece to be cut. See also Figure 2As shown, to facilitate operator control of the rotation of turntable 1 in manual mode, one or more rotating handles 8 are fixed on the upper surface or side edge of turntable 1. The operator can apply rotational torque to turntable 1 by holding the rotating handles 8, thereby controlling the rotation of the workpiece.

[0030] The locking mechanism 3 is used to achieve automatic workpiece centering and is one of the key components to ensure high-precision cutting. The following will combine... Figures 2-4 Explain the organization, including Figure 2 This is a detailed structural diagram of the locking mechanism 3. For an optional implementation, see [link to diagram]. Figure 3 and Figure 4 As shown, the locking mechanism 3 includes a rotating shaft 31 and clamping blocks 32. A rotating shaft 21 is rotatably connected to the center of the base 2. The rotating shaft 21 is fixedly connected to the turntable 1 via a connecting block 34, and there is a longitudinal gap between the turntable 1 and the base 2. The rotating shaft 31 is horizontally positioned, passes through the connecting block 34, and is rotatably connected to it. The rotating shaft 31 is drively connected to two clamping blocks 32. Rotating the rotating shaft 31 can drive the two clamping blocks 32 to move towards or away from each other, thereby clamping or releasing the mold 100. The rotating shaft 31 is a single-piece metal rod, for example, made of high-strength alloy steel and machined by CNC turning.

[0031] See Figure 3 and Figure 4 As shown, at least one end of the rotating shaft 31 is fixed with a rotating handle 33, which is rotatably connected to the turntable 1 and is used to drive the rotating shaft 31 to rotate under the action of external force.

[0032] In this embodiment, the locking mechanism 3 rotates the rotating shaft 31 by manually rotating the rotating handle 33, thereby enabling the two clamping blocks 32 to clamp or release the mold 100, which is convenient for manual operation by the operator and facilitates clamping and positioning of the mold 100.

[0033] See Figure 4 As shown, the rotating shaft 31 in this embodiment includes an integrally formed right-hand rotating shaft segment 311 and a left-hand rotating shaft segment 312, wherein: one clamping block 32 is threadedly connected to the right-hand rotating shaft segment 311, and the other clamping block 32 is threadedly connected to the left-hand rotating shaft segment 312; a horizontal slot 11 is provided on the turntable 1, and the clamping block 32 passes through the slotted extension support of the upper part of the turntable 1. When the rotating shaft 31 is rotated, the two clamping blocks 32 can move towards each other or away from each other along the horizontal slot 11.

[0034] See Figure 4As shown, the middle portion of the rotating shaft 31 is machined into two sections with opposite helical directions: a right-hand rotating shaft section 311 and a left-hand rotating shaft section 312. It should be noted that the pitch, diameter, and other parameters of these two thread sections are identical; only the helical directions are opposite. This one-piece molding structure ensures extremely high coaxiality between the left and right thread sections, thereby ensuring high transmission accuracy, strong structural rigidity, and durability.

[0035] Two clamping blocks 32 that mate with the rotating shaft 31. See also Figure 2 The upper surface of the turntable 1 has two parallel horizontal slots 11 along the axial direction of the rotation shaft 31. The base of each clamping block 32 has an internal thread structure that matches the thread of the rotation shaft 31, and is threadedly connected to the right-hand rotating shaft segment 311 and the left-hand rotating shaft segment 312, respectively. The main body of the clamping block 32 extends through the horizontal slots 11 on the turntable 1 above the turntable 1, forming a clamping surface on the side facing the workpiece. As an optional implementation, to protect the surface of the composite hose 200, a softer material, such as polyurethane or a rubber pad, can be applied to the clamping surface.

[0036] When the operator turns the rotary handle 33, the rotary shaft 31 rotates accordingly. It is understood that, since the two clamping blocks 32 are threadedly engaged with the right-hand rotary shaft segment 311 and the left-hand rotary shaft segment 312 with opposite directions of rotation, one clamping block 32 will move to one side along the rotary shaft 31, while the other clamping block 32 will move to the other side at the exact same speed. Through this synchronized opposing or reciprocating movement, regardless of whether the initial placement position of the workpiece is off-center, the two clamping blocks 32 can always automatically clamp the workpiece (here, the workpiece is the mold 100, e.g.) during the clamping process. Figure 2 and Figure 3 (As shown) The workpiece is pushed towards and ultimately fixed on the rotation center line of turntable 1, thereby achieving automatic centering and clamping of the workpiece. This fundamentally eliminates the workpiece rotational wobbling caused by clamping eccentricity, laying a solid foundation for subsequent high-precision cutting. When it is necessary to release the workpiece, simply rotate the rotating handle 33 in the opposite direction, and the two clamping blocks 32 will move synchronously in opposite directions, thereby releasing the workpiece.

[0037] See Figure 2 and Figure 6 As shown, the cutting component 4 is used to achieve flexible and precise adjustment of the cutting position in two-dimensional space. In this embodiment, the position of the cutting component 4 in the horizontal direction (i.e., the direction parallel to the axis of rotation 31) is adjustable.

[0038] As an alternative implementation, see [link to implementation details]. Figure 2 and Figure 6As shown, the composite flexible tube cutting device of this embodiment also includes a horizontal guide rail 5 and a movable seat 6, wherein: the horizontal guide rail 5 is fixed on the base 2 and located on the side of the turntable 1; the movable seat 6 is slidably connected to the horizontal guide rail 5; a locking rod 7 passes through the movable seat 6 and can move the movable seat 6 to the target position of the horizontal guide rail 5; the cutting component 4 is located on the movable seat 6 and moves horizontally with the movable seat 6, thereby adjusting the horizontal position of the cutting component 4.

[0039] See Figure 2 As shown, the locking lever 7 can be, for example, a handle-type locking screw, which, when tightened, can securely lock the movable seat 6 at any position on the horizontal guide rail 5.

[0040] To further enable vertical position adjustment of the cutting component 4, see [link / reference]. Figure 2 and Figure 6 The locking and cutting assembly 4 also includes a drive device 42 and a bracket 43, wherein: the drive device 42 is fixed on the bracket 43, the drive device 42 is driven connected to the cutting blade 41, and is used to drive the cutting blade 41 to rotate; the bracket 43 is slidably connected to the movable seat 6, and the position of the bracket 43 in the vertical direction is adjustable; a scale 44 is installed on the bracket 43 for measuring the vertical distance between the cutting blade 41 and the upper surface of the turntable 1.

[0041] See Figure 2 and Figure 6 As shown, bracket 43 is the mounting platform for cutting assembly 4. In this embodiment, a drive device 42 is fixedly mounted on bracket 43. The drive device 42 (such as a drive motor) can be a high-speed DC motor or an AC spindle motor, and its output shaft is connected to the cutting tool via a chuck or flange. Battery 10 powers the drive device 42. The cutting tool is preferably a thin-walled cutting blade 41, such as a diamond cutting blade or a carbide saw blade. Such blades can achieve fast and smooth cutting of composite materials under high-speed rotation, and produce fewer burrs.

[0042] To further enable the vertical position adjustment of the cutting component 4, as an optional implementation, the movable seat 6 includes a horizontal section 61 and a vertical section 62 that are fixedly connected, wherein: the horizontal section 61 is slidably connected to the horizontal guide rail 5, the bracket 43 is slidably connected to the vertical section 62, and a locking screw 9 passes through the vertical section 62 to lock the bracket 43 at the target position of the vertical section 62, thereby adjusting the vertical position of the cutting component 4.

[0043] See Figure 2 and Figure 6As shown, the vertical section 62 of the movable base 6 has a vertical guide rail structure, such as a dovetail groove or a rectangular slide. The bracket 43 slides in conjunction with this vertical guide rail. The vertical height of the bracket 43 can be precisely adjusted and locked by a lead screw adjustment mechanism or a simple locking screw 9 provided on the movable base 6. With the above-mentioned adjustment mechanisms in both the horizontal and vertical directions, the operator can easily and precisely align the cutting edge of the cutting tool with the pre-marked cutting line on the composite flexible tube 200, thereby ensuring the accuracy of the cutting length.

[0044] To ensure operational safety, as an optional implementation method, see [link to alternative implementation]. Figure 6 As shown, the cutting assembly 4 also includes a protective cover 45, which is fixedly connected to the bracket 43. The protective cover 45 is disposed outside the cutting blade 41, and an opening slot 46 is provided on the side of the protective cover 45 facing the mold 100, with a part of the cutting blade 41 extending out of the opening slot 46.

[0045] See Figure 6 As shown, the protective cover 45 has the aforementioned opening slot 46 only on the side facing the workpiece to allow the cutting blade 41 to extend for operation, while in other directions it can effectively block chip splashes and prevent accidental contact.

[0046] The composite flexible tube cutting device of this embodiment operates as follows: Step S101, place the workpiece. Place a composite flexible tube 200 with process allowances at both ends to be cut roughly on the turntable 1, between the two clamping blocks 32. Step S102, synchronous centering and clamping. Operate the rotating handle 33 to drive the rotating shaft 31 to rotate, causing the two clamping blocks 32 to move synchronously towards each other, thereby automatically pushing and clamping the composite hose 200 to the rotation center of the turntable 1. Because it is synchronous centering, this process does not require repeated adjustment of the workpiece position, making the operation simple and quick. Step S103, adjust the cutting position. After clamping, adjust the horizontal and vertical positions of the cutting assembly 4. By visual inspection or with the help of the aforementioned ruler 44, ensure that the cutting edge of the high-speed rotating cutting blade 41 is precisely aligned with the cutting mark line on the workpiece. Then tighten all locking devices to securely position the cutting assembly 4. Step S104: Perform rotary cutting. Start the drive device 42 to make the cutting blade 41 reach a stable speed. Then, the operator holds the rotating handle 8 and rotates the turntable 1 at a uniform speed and smoothly, driving the clamped composite hose 200 to rotate, thereby completing the ring cut.

[0047] Because the workpiece rotates concentrically and the cutting blade 41 is fixed in position, the cutting process is stable, the cutting depth is uniform, and the final cut is flat and smooth, with the end face strictly perpendicular to the axis of the hose. Step S105: Release the workpiece. After cutting one end, turn off the drive device 42 and rotate the handle 33 in the opposite direction to make the two clamping blocks 32 move synchronously in opposite directions to release the composite hose 200. Then, the workpiece direction can be reversed, and the above steps can be repeated to cut the other end to obtain a finished hose of precise length.

[0048] In this embodiment, by setting a rotating shaft 31 including a right-hand rotating shaft segment 311 and a left-hand rotating shaft segment 312, the two clamping blocks 32 are driven to move synchronously towards or away from each other, which can realize automatic centering and clamping of the workpiece. This structure ensures that the workpiece always remains concentric during rotation, fundamentally avoiding the problems of uneven cutting depth and skewed cut caused by eccentricity, effectively ensuring the flatness of the cut and the perpendicularity to the workpiece axis, and strictly controlling the length tolerance of the cut, thereby significantly improving the cutting accuracy and quality.

[0049] Meanwhile, compared to traditional manual cutting methods, this application simplifies the operation process significantly by using mechanized clamping, positioning, and rotary cutting, resulting in faster cutting speeds and a marked improvement in production efficiency. Furthermore, automatic workpiece centering and clamping can be achieved by operating a single rotating axis 31, making operation intuitive and convenient, with a stable and reliable structure. This reduces reliance on operator skills and ensures consistent processing quality.

[0050] In this embodiment, the diameter of the product to be cut can range from φ35mm to φ200mm, which includes 95% of the diameter of aviation composite hoses currently available; the cutting height can range from 25mm to 90mm from the bottom of the mold. For excessively tall molds and products, the other end of the mold can be reinstalled with a reference surface. The length of the product can be controlled and cut by calculating and measuring the total length of the mold and controlling the distance between the two ends of the product and the mold end face.
