Description

Technical Field

[0001] The invention relates to the technical field of pipe shearing equipment, and in particular to an automatic batch pipe cutting system for motorcycle cylinder piston tubes. Background Art

[0002] A motorcycle engine cylinder block consists of many separately produced parts, among which the cylinder piston tube is one of the key parts. After the piston tube is produced, it needs to be cut to the corresponding length and then undergo subsequent processes such as polishing and installation into the cylinder block.

[0003] In the past, cylinder piston tubes were mainly cut manually, but manual cutting relied entirely on experience, resulting in large length errors after cutting, low efficiency, and high scrap rate. However, due to the thicker wall of motorcycle cylinder piston tubes, conventional tube cutting equipment usually uses a circular cutting knife. During cutting, the tube is fixed, and the cutting knife rotates and moves from one side to the other. During the process of cutting the tube, the separation position is from one side to the other. The cutter needs to feed a long distance, and the cutting force is concentrated. The cutter is prone to chipping and deformation, and the end face of the tube is also prone to burrs and unevenness. To solve this problem, an existing automatic tube cutting system for motorcycle cylinder piston tubes is used. The system cuts the tube in a manner that the tube rotates, the cutter does not rotate, and feeds in a fixed direction. When cutting the tube, the separation area of ​​the tube gradually transitions from the outer wall to the inner wall, which solves a series of problems caused by conventional tube cutting methods, such as easy wear of the cutter and uneven end face of the tube.

[0004] However, the existing automatic pipe cutting system has low cutting efficiency. Each cycle of pipe drawing and cutting can only cut a section, which is inefficient. It is often necessary to set up multiple automatic pipe cutting systems to run synchronously so as not to affect the production of other equipment on the production line. Therefore, improvement is needed.

For example, they may refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention in specific contexts.

[0044] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments.

[0045] like Figures 1 to 6 As shown, this embodiment provides an automated batch pipe cutting system for motorcycle cylinder piston tubes, comprising a horizontally arranged top plate 5 and a bottom plate 6, as well as a plurality of pipe cutting assemblies 2 arranged on the top of the bottom plate 6 and a synchronous pushing assembly 3 arranged on the bottom of the top plate 5;

[0046] The mounting top plate 5 and the mounting bottom plate 6 are respectively provided with a plurality of coaxially arranged first through holes 51 and second through holes 61, and the pipe cutting assembly 2 has a pipe cutting channel coaxially arranged with the first through holes 51 and the second through holes 61;

[0047] The pipe cutting assembly 2 includes a coaxially arranged transmission sleeve 21 and a guide sleeve 22, and a cutting blade 23 radially connected to the guide sleeve 22 in a sliding manner. The guide sleeve 22 is arranged in the transmission sleeve 21 and rotates synchronously with the transmission sleeve 21.

[0048] The synchronous pushing assembly 3 is used to drive the multiple cutting knives 23 to move radially inward along the guide sleeve 22;

[0049] It also includes multiple pipe clamping assemblies 4 arranged on the synchronous pushing assembly 3 and used to clamp and loosen the pipe body 1, as well as a trustee assembly 8 arranged at the bottom of the mounting chassis 6 and a driving assembly 7 for driving the transmission sleeve 21 and guide sleeve 22 of the multiple pipe cutting assemblies 2 to rotate synchronously.

[0050] This embodiment provides multiple tube clamping assemblies 4, tube cutting assemblies 2, synchronous pushing assemblies 3, and drive assembly 7. When the present application is in use, after the multiple tube clamping assemblies 4 clamp the tube body 1, the drive assembly 7 is activated to simultaneously drive the multiple tube cutting assemblies 2 to rotate, thereby causing the multiple cutting blades 23 to rotate along the circumference of the tube body 1. Meanwhile, the synchronous pushing assembly 3 can simultaneously cause the multiple cutting blades 23 to move radially inward along the guide sleeve 22. Therefore, through the coordinated cooperation of the synchronous pushing assembly 3, the drive assembly 7, and the tube cutting assembly 2, multiple tube bodies 1 can be cut simultaneously. Furthermore, during the cutting process of the tube body 1, the separation area of ​​the tube gradually transitions from the outer peripheral wall to the inner peripheral wall, ensuring the flatness of the rear end surface of the tube body 1 after cutting. This effectively solves the problem that conventional motorcycle cylinder piston tube cutting cannot automatically cut tubes from the outside to the inside in batches.

[0051] In this embodiment, the cutting cycle of a single pipe mainly includes the following actions:

[0052] First, the driving cylinder of the hosting assembly 8 drives the L-shaped support plate 82 to move to the position directly below the second through hole 61. Then, the clamping assembly 4 is relaxed. The pipe body 1 is no longer clamped by the clamping assembly 4. Under the action of gravity, the pipe body 1 falls onto the L-shaped support plate 82. At this time, the photoelectric detection assembly 9 can detect the sensor signal of the pipe body 1 falling onto the L-shaped support plate 82. At the same time, the pushing cylinder 32 is driven to move upward and reset. At this time, the next action can be started.

[0053] Second, the drive motor 71 of the drive assembly 7 is started, thereby driving all the cutting assemblies to rotate synchronously. At the same time, the multiple clamping assemblies 4 clamp the pipe body 1, so that the pipe body 1 cannot rotate freely. At this time, there is a certain gap between the pipe body 1 and the cutting blade 23 of the pipe cutting assembly 2, and the rotating cutting blade 23 enters the pipe cutting preparation state;

[0054] 3. The driving cylinder of the hosting assembly 8 drives the L-shaped supporting plate 82 to move away from directly below the second through hole 61. Since the pipe body 1 has been clamped by the pipe clamping assembly 4, the pipe body 1 will not fall freely at this time.

[0055] Fourth, the pushing cylinder 32 of the synchronous pushing assembly 3 will push the synchronous pushing plate 31 to move downward, so that the synchronous pushing plate 31 will push the guide sleeves 22 of multiple pipe cutting assemblies 2 to move downward at the same time, thereby causing the cutting knife 23 on the guide sleeve 22 to be pushed by the conical pushing surface 212 of the transmission sleeve 21, so that the cutting knife 23 continues to move inward along the radial direction of the guide sleeve 22, while the cutting knife 23 is still in the process of continuous rotation, so that the cutting knife 23 will continue to cut from the outer circumferential wall to the inner circumferential wall of the pipe body 1 as the synchronous pushing plate 31 moves downward until the pipe body 1 is cut off. Under the action of gravity, the cut part of the pipe body 1 falls down, and the transmitting end 91 and the receiving end 92 of the photoelectric detection assembly 9 are reconnected. At this time, it can be judged that the current action is completed based on the detection signal.

[0056] In this embodiment, the inner circumferential wall of the transmission sleeve 21 is provided with a limiting sliding groove 211, and the outer circumference of the guide sleeve 22 is provided with a limiting sliding bar 221 adapted to the limiting sliding groove 211. The transmission sleeve 21 and the guide sleeve 22 rotate synchronously through the limiting sliding groove 211 and the limiting sliding bar 221;

[0057] A conical pushing surface 212 is provided on the upper portion of the inner peripheral wall of the transmission sleeve 21 , and one end of the cutting blade 23 close to the outer peripheral wall of the guide sleeve 22 is arranged facing the conical pushing surface 212 .

[0058] By providing the limiting sliding groove 211 and the limiting sliding bar 221 , the guide sleeve 22 can slide along its axial direction in the transmission sleeve 21 , while ensuring that the guide sleeve 22 and the transmission sleeve 21 do not rotate relative to each other.

[0059] When the guide sleeve 22 moves downward, the conical pushing surface 212 can make the cutting blade 23 continuously move inward along the radial direction of the guide sleeve 22 , and the cutting blade 23 can slide in contact with the conical pushing surface 212 along the circumference of the guide sleeve 22 .

[0060] In this embodiment, Figure 5 As shown, the cutting knife 23 includes a knife body 231 and a pressing arc rod 232 that are fixedly connected, and the knife body is arranged along the radial direction corresponding to the arc where the pressing arc rod 232 is located;

[0061] The guide sleeve 22 is provided with a cutting knife guide hole 222 , and the blade body 231 of the cutting knife 23 is slidably connected to the cutting knife guide hole 222 . The pressing arc rod 232 is located between the guide sleeve 22 and the conical pushing surface 212 of the transmission sleeve 21 .

[0062] In this embodiment, the radius of the arc of the outer peripheral wall of the pressing arc rod 232 is larger than the radius of the inner peripheral wall of the transmission sleeve 21 .

[0063] In this embodiment, if Figure 1As shown, a limiting step 213 is further provided at the bottom of the inner circumferential wall of the transmission sleeve 21 .

[0064] In this embodiment, Figure 1 and Figure 6 As shown, the synchronous push assembly 3 includes a synchronous push plate 31 arranged horizontally and located between the mounting top plate 5 and the mounting bottom plate. The synchronous push plate 31 is provided with a plurality of third through holes 311 coaxially arranged with the first through holes 51 and the second through holes 61. The inner peripheral wall of the third through holes 311 of the synchronous push plate 31 is provided with a mounting annular groove 312.

[0065] The pipe clamping assembly 4 is installed on the top of the synchronous pushing plate 31;

[0066] The top of the guide sleeve 22 is provided with a guide annular projection that is disposed within and slidably connected to a mounting annular groove 312. By providing the guide annular projection on the top of the guide sleeve 22 and the mounting annular groove 312 within the third through hole 311 of the synchronous push plate 31, the guide sleeve 22 and the synchronous push plate 31 can rotate relative to each other in the circumferential direction while preventing relative axial movement between the guide sleeve 22 and the synchronous push plate 31.

[0067] In some embodiments, a plurality of balls may be provided between the mounting ring protrusion and the mounting ring groove 312 to reduce the friction resistance when the guide sleeve 22 and the synchronous push plate 31 rotate relative to each other, thereby reducing the energy consumption of the entire system.

[0068] In this embodiment, the tube clamping assembly 4 includes a fixed clamping block 42 and a tube clamping cylinder 41 fixed on the synchronous pushing plate 31, and a movable clamping block 43 provided on the output shaft of the tube clamping cylinder 41. The movable clamping block 43 and the fixed clamping block 42 are respectively located on both sides of the central axis of the third through hole 311. The tube clamping assembly 4 is fixed on the synchronous pushing plate 31, so that after the tube clamping assembly 4 clamps the pipe body 1, when the synchronous pushing plate 31 moves downward, it drives the guide sleeve 22 to move downward, so that when the cutting knife 23 on the guide sleeve 22 moves downward, the clamped pipe body 1 moves downward synchronously, so that the cutting position of the pipe body 1 and the cutting knife 23 always remains relatively fixed, ensuring that the cutting of the pipe body 1 is stable and the cut end surface of the pipe body 1 is kept flat.

[0069] In this embodiment, the opposite sides of the movable clamping block 43 and the fixed clamping block 42 are both arc-shaped curved surfaces, so that the clamping of the pipe body 1 is more stable.

[0070] In this embodiment, a hosting assembly 8 is further included, which is provided at the bottom of the mounting chassis 6;

[0071] The trustee assembly 8 includes a trustee cylinder 81 fixed to the bottom of the mounting chassis 6 and an L-shaped support plate 82 provided on the output shaft of the trustee cylinder 81;

[0072] The hosting component 8 has two working states:

[0073] State 1: The L-shaped support plate 82 is located directly below the second through hole 61 and can support the main body 1 of the tube.

[0074] State 2: The L-shaped supporting plate 82 is away from the bottom of the second through hole 61 , and the pipe body 1 can freely fall through the second through hole 61 to the bottom of the hosting assembly 8 .

[0075] This embodiment provides a trustee assembly 8, which utilizes the weight of the pipe body 1 to fall downward, thereby not only opening and closing the valve, but also aligning the pipe body 1, ensuring that the pipe sections cut from the pipe body 1 are of uniform length, thereby avoiding subsequent secondary processing of the pipe body 1.

[0076] In this embodiment, it also includes a plurality of photoelectric detection components 9 arranged at the bottom of the mounting chassis 6. The photoelectric detection component 9 includes a receiving end 92 and a transmitting end 91. The light channel between the receiving end 92 and the transmitting end 91 passes horizontally through the central axis line of the second through hole 61. The photoelectric detection component 9 in this embodiment is a common photoelectric sensor and will not be described here.

[0077] The pipe sections cut from the pipe body 1 are of uniform length, the plurality of pipe cutting assemblies 2 are evenly distributed along the circumference of the mounting base 6, and the transmission sleeves 21 of the pipe cutting assemblies 2 are all rotatably connected to the top of the mounting base 6;

[0078] The driving assembly 7 includes a driving motor 71 and a driving gear 72 driven by an output shaft of the driving motor 71;

[0079] A driven gear ring 214 is provided on the outer peripheral wall of the transmission sleeve 21. The driven gear rings 214 of multiple transmission sleeves 21 are all engaged with the driving gear 72. In some embodiments, a transmission structure such as an annular gear ring and a synchronous belt can also be provided to drive the driven gear rings 214 of multiple transmission sleeves 21. No further examples are given here.

[0080] In this embodiment, Figure 1 and Figure 6As shown, the synchronous pushing assembly 3 also includes a pushing cylinder 32 invertedly arranged at the bottom of the mounting top plate 5, and a guide rod 33 vertically arranged at the top of the synchronous pushing plate 31. The guide rod 33 is arranged through the mounting top plate 5 and is slidably connected thereto, and the output end of the pushing cylinder 32 is fixedly connected to the top of the synchronous pushing plate 31. The pushing cylinder 32 can push the synchronous pushing plate 31 up or down, so that the cutting knives 23 of multiple guide sleeves 22 can move inward along the radial direction of the guide sleeve 22 at the same time, or the multiple guide sleeves 22 can move up at the same time, and the multiple cutting knives 23 are no longer subjected to the pushing force of moving inward along the radial direction of the guide sleeve 22. The pushing cylinder 32 in this embodiment can also be replaced with a pushing oil cylinder or other types of linear drives and actuators, which are not described here.

[0081] It will be understood that the above embodiments are merely exemplary embodiments for illustrating the principles of the present invention, and the present invention is not limited thereto. Those skilled in the art will be able to make various modifications and improvements without departing from the spirit and substance of the present invention, and such modifications and improvements are also considered to be within the scope of protection of the present invention.
