Description

Technical Field

[0001] The present invention relates to the technical field of pipe cutting equipment, and particularly relates to an automatic batch pipe cutting system for motorcycle cylinder block piston pipes. Background Art

[0002] A motorcycle engine cylinder block includes many separately produced components. Among them, the cylinder block piston pipe is one of the key components. After the production of the piston pipe is completed, it needs to be cut to the corresponding length, and then undergo subsequent processes such as grinding and installation into the cylinder block.

[0003] In the past, the cylinder block piston pipes were mainly cut manually. However, manual cutting depends entirely on experience, resulting in large length errors, low efficiency, and high rejection rates after cutting. Due to the relatively thick wall of the motorcycle cylinder block piston pipe, conventional pipe cutting equipment usually has a circular cutting tool. During cutting, the pipe is fixed, and the cutting tool rotates and moves from one side to the other. During the process of cutting the pipe, the separated position is from one side to the other, and the cutting tool needs to feed a long distance, and the cutting force is concentrated, so the cutting tool is prone to chipping and deformation, and the end face of the pipe is also prone to problems such as burrs and unevenness. To solve this problem, an existing automatic pipe cutting system for motorcycle cylinder block piston pipes cuts the pipe in a way that the pipe rotates and the cutting tool does not rotate and feeds along a fixed direction. When cutting the pipe, the separation area of the pipe gradually transitions from the outer peripheral wall to the inner peripheral wall, solving a series of problems such as easy wear of the cutting tool and uneven end face of the pipe caused by the conventional pipe cutting method.

[0004] However, the existing automatic pipe cutting system has low cutting efficiency. Each cycle of pulling and cutting the pipe can only cut one section, with low efficiency. Often, multiple automatic pipe cutting systems need to run synchronously to avoid affecting the production of other equipment on the production line. Therefore, improvements are needed.

[0005] Based on the above background, the inventor designed an automatic batch pipe cutting system for motorcycle cylinder block piston pipes to solve at least one of the above problems, and thus, this application is proposed. Summary of the Invention

[0028] The present invention will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0029] As Figures 1 to 6 shown, this embodiment provides an automated batch pipe cutting system for a motorcycle cylinder piston pipe, which includes a horizontally arranged mounting top plate 5 and a mounting bottom plate 6, as well as a plurality of pipe cutting assemblies 2 provided on the top of the mounting bottom plate 6 and a synchronous pushing and pressing assembly 3 provided at the bottom of the mounting top plate; A plurality of coaxially arranged first through holes 51 and second through holes 61 are respectively provided on the mounting top plate 5 and the mounting bottom plate 6, and a pipe cutting channel coaxially arranged with the first through hole 51 and the second through hole 61 is provided inside the pipe cutting assembly 2; The pipe cutting assembly 2 includes a coaxially arranged transmission sleeve 21 and a guide sleeve 22, and a cutting knife 23 slidably connected to the guide sleeve 22 along its radial direction. The guide sleeve 22 is arranged inside the transmission sleeve 21 and rotates synchronously therewith; The synchronous pushing and pressing assembly 3 is used to drive a plurality of cutting knives 23 to move radially inward along the guide sleeve 22; It also includes a plurality of pipe clamping assemblies 4 provided on the synchronous pushing and pressing assembly 3 and used for clamping and releasing the pipe body 1, a pipe supporting assembly 8 provided at the bottom of the mounting bottom plate 6, and a driving assembly 7 used for driving the transmission sleeves 21 and the guide sleeves 22 of the plurality of pipe cutting assemblies 2 to rotate synchronously.

[0030] In this embodiment, by providing a plurality of pipe clamping assemblies 4, pipe cutting assemblies 2, a synchronous pushing and pressing assembly 3 and a driving assembly 7, when the present application is in use, after the plurality of pipe clamping assemblies 4 clamp the pipe body 1, the driving assembly 7 can be enabled to drive the plurality of pipe cutting assemblies 2 to rotate simultaneously, so that the plurality of cutting knives 23 rotate circumferentially along the pipe body 1, and the synchronous pushing and pressing assembly 3 can simultaneously make the plurality of cutting knives 23 move radially inward along the guide sleeve 22. Therefore, through the mutual cooperation of the synchronous pushing and pressing assembly 3, the driving assembly 7 and the pipe cutting assembly 2, a plurality of pipe bodies 1 can be cut simultaneously, and during the cutting process of the pipe body 1, the separation area of the pipe gradually transitions from the outer peripheral wall to the inner peripheral wall, which can ensure the flatness of the end face of the pipe body 1 after cutting, effectively solving the problem that the existing motorcycle cylinder piston pipe cutting cannot batch realize the automatic cutting of the pipe from the outside to the inside.

[0031] In this embodiment, in the cutting cycle of a single pipe fitting, the following operations are mainly included: First, the driving cylinder of the hosting assembly 8 drives the L-shaped pallet 82 to move to directly below the second through hole 61. Subsequently, the pipe clamping assembly 4 relaxes, and the pipe body 1 is no longer clamped by the pipe clamping assembly 4 at this time. Under the action of gravity, the pipe body 1 drops onto the L-shaped pallet 82. At this time, the photoelectric detection assembly 9 can detect the sensing signal of the pipe body 1 dropping onto the L-shaped pallet 82. Meanwhile, the pushing cylinder 32 drives upward to reset. At this time, the next operation can be started; Second, the driving motor 71 of the driving assembly 7 starts, thereby driving all the cutting assemblies to rotate synchronously. Meanwhile, multiple pipe clamping assemblies 4 clamp the pipe body 1, so that the pipe body 1 will not 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 state of preparing to cut the pipe; Third, the driving cylinder of the hosting assembly 8 drives the L-shaped pallet 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 at this time, the pipe body 1 will not have the problem of free falling; Fourth, the pushing cylinder 32 of the synchronous pushing assembly 3 will push the synchronous pushing disc 31 downward, so that the synchronous pushing disc 31 simultaneously pushes the guiding sleeves 22 of multiple pipe cutting assemblies 2 downward. As a result, the cutting blade 23 on the guiding sleeve 22 is pushed by the conical pushing surface 212 of the transmission sleeve 21, so that the cutting blade 23 continuously moves radially inward along the guiding sleeve 22. While the cutting blade 23 is still in the process of continuous rotation, the cutting blade 23 will continuously cut from the outer peripheral wall of the pipe body 1 to the inner peripheral wall as the synchronous pushing disc 31 moves downward until the pipe body 1 is cut off. Under the action of gravity, the cut-off part of the pipe body 1 drops downward, and the transmitting end 91 and the receiving end 92 of the photoelectric detection assembly 9 are reconnected. At this moment, it can be judged that the current operation is completed according to the detection signal.

[0032] In this embodiment, a limiting sliding groove 211 is provided on the inner peripheral wall of the transmission sleeve 21, and a limiting sliding strip 221 adapted to the limiting sliding groove 211 is provided on the outer periphery of the guiding sleeve 22. The transmission sleeve 21 and the guiding sleeve 22 rotate synchronously through the limiting sliding groove 211 and the limiting sliding strip 221; The upper part of the inner peripheral wall of the transmission sleeve 21 is provided with a conical pushing surface 212, and one end of the cutting blade 23 close to the outer peripheral wall of the guiding sleeve 22 is arranged towards the conical pushing surface 212.

[0033] By providing the limiting sliding groove 211 and the limiting sliding strip 221, the guiding sleeve 22 can slide axially in the transmission sleeve 21, and at the same time, it is ensured that the guiding sleeve 22 and the transmission sleeve 21 do not rotate relative to each other.

[0034] When the guiding sleeve 22 moves downward, the conical pressing surface 212 can cause the cutting tool 23 to continuously move radially inward along the guiding sleeve 22, and the cutting tool 23 can be in sliding contact with the conical pressing surface 212 along the circumferential direction of the guiding sleeve 22.

[0035] In this embodiment, as Figure 5 shown, the cutting tool 23 includes a tool body part 231 and a pressing arc rod 232 which are fixedly connected, and the tool body is arranged radially corresponding to the arc where the pressing arc rod 232 is located; A cutting tool guiding hole 222 is provided on the guiding sleeve 22, the tool body part 231 of the cutting tool 23 is slidably connected with the cutting tool guiding hole 222, and the pressing arc rod 232 is located between the guiding sleeve 22 and the conical pressing surface 212 of the driving sleeve 21.

[0036] In this embodiment, the radius corresponding to the outer peripheral wall arc of the pressing arc rod 232 is greater than the radius corresponding to the inner peripheral wall of the driving sleeve 21.

[0037] In this embodiment, as Figure 1 shown, a limiting step 213 is further provided at the bottom of the inner peripheral wall of the driving sleeve 21.

[0038] In this embodiment, as Figure 1 and Figure 6 shown, the synchronous pressing assembly 3 includes a synchronous pressing disc 31 which is horizontally arranged and located between the installation top disc 5 and the installation bottom plate. A plurality of third through holes 311 coaxial with the first through hole 51 and the second through hole 61 are provided on the synchronous pressing disc 31, and an installation ring groove 312 is provided on the inner peripheral wall of the third through hole 311 of the synchronous pressing disc 31; The pipe clamping assembly 4 is installed on the top of the synchronous pressing disc 31; A guiding ring convex is provided at the top of the guiding sleeve 22 and is arranged in and slidably connected with the installation ring groove 312. By providing the guiding ring convex at the top of the guiding sleeve 22 and the installation ring groove 312 in the third through hole 311 of the synchronous pressing disc 31, relative circumferential rotation can occur between the guiding sleeve 22 and the synchronous pressing disc 31. At the same time, relative axial movement does not occur between the guiding sleeve 22 and the synchronous pressing disc 31.

[0039] In some embodiments, a plurality of balls can be further arranged between the installation ring convex and the installation ring groove 312 to reduce the frictional resistance when the guiding sleeve 22 and the synchronous pressing disc 31 rotate relatively, and reduce the energy consumption of the whole system.

[0040] In this embodiment, the pipe clamping assembly 4 includes a fixed clamping block 42 fixed on the synchronous pushing and pressing disc 31, a pipe clamping cylinder 41, and a movable clamping block 43 arranged on the output shaft of the pipe 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 pipe clamping assembly 4 is fixed on the synchronous pushing and pressing disc 31, so that after the pipe clamping assembly 4 clamps the pipe body 1, when the synchronous pushing and pressing disc 31 moves downward, it drives the guide sleeve 22 to move downward. When the cutting knife 23 on the guide sleeve 22 moves downward, the clamped pipe body 1 moves downward synchronously, so that the position where the pipe body 1 is cut by the cutting knife 23 always remains relatively fixed, ensuring the stable cutting of the pipe body 1 and keeping the cutting end face of the pipe body 1 flat.

[0041] In this embodiment, the opposite sides of the movable clamping block 43 and the fixed clamping block 42 are both arc-shaped curved surfaces, making the clamping of the pipe body 1 more stable.

[0042] In this embodiment, it further includes a pipe supporting component 8 arranged at the bottom of the installation chassis 6; The pipe supporting component 8 includes a pipe supporting cylinder 81 fixed at the bottom of the installation chassis 6 and an L-shaped supporting plate 82 arranged on the output shaft of the pipe supporting cylinder 81; The pipe supporting component 8 has two working states: State 1: The L-shaped supporting plate 82 is located directly below the second through hole 61, and the L-shaped supporting plate 82 can play a role in supporting the pipe body 1; State 2: The L-shaped supporting plate 82 is far away from directly below the second through hole 61, and the pipe body 1 can freely fall below the pipe supporting component 8 through the second through hole 61.

[0043] In this embodiment, by setting the pipe supporting component 8 and using the self-weight of the pipe body 1 to fall downward, it can not only play the role of opening and closing the valve, but also play the role of aligning the pipe body 1, ensuring that the lengths of the pipe segments cut from the pipe body 1 are consistent, and avoiding secondary processing of the pipe body 1 subsequently.

[0044] In this embodiment, it further includes a plurality of photoelectric detection components 9 arranged at the bottom of the installation 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 is arranged 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 elaborated here.

[0045] The lengths of the pipe segments cut from the pipe body 1 are consistent. The plurality of pipe cutting assemblies 2 are evenly distributed along the circumference of the installation chassis 6, and the transmission sleeves 21 of the pipe cutting assemblies 2 are all rotatably connected to the top of the installation chassis 6; The driving component 7 includes a driving motor 71 and a driving gear 72 driven by the output shaft of the driving motor 71; 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 meshed with the driving gear 72. In some embodiments, a transmission structure such as an annular gear ring or a synchronous belt can also be provided to drive the driven gear rings 214 of multiple transmission sleeves 21, and no further examples will be given here.

[0046] In this embodiment, as Figure 1 and Figure 6 shown, the synchronous pressing assembly 3 further includes a pressing cylinder 32 inversely arranged at the bottom of the installation top plate 5, and a guide rod 33 vertically arranged on the top of the synchronous pressing plate 31. The guide rod 33 penetrates through the installation top plate 5 and is slidably connected thereto. The output end of the pressing cylinder 32 is fixedly connected to the top of the synchronous pressing plate 31. The pressing cylinder 32 can push the synchronous pressing plate 31 to move up or down, which can make the cutting knives 23 of multiple guide sleeves 22 move inward along the radial direction of the guide sleeves 22 at the same time, or make multiple guide sleeves 22 move upward at the same time, and the multiple cutting knives 23 no longer receive the pushing force moving inward along the radial direction of the guide sleeves 22. The pressing cylinder 32 in this embodiment can also be replaced with a pressing oil cylinder or other types of linear driving mechanisms, which will not be elaborated here.

[0047] It can be understood that the above embodiments are merely exemplary embodiments adopted to illustrate the principle of the present invention. However, the present invention is not limited thereto. For those of ordinary skill in the art, various deformations and improvements can be made without departing from the spirit and essence of the present invention, and these deformations and improvements are also regarded as the protection scope of the present invention.
