Description

Technical Field

[0001] This invention relates to the field of metal cutting technology, and more specifically to a cutting device for a handlebar switch assembly. Background Technology

[0002] In the manufacturing process of handlebar switch assemblies, the cutting of metal tubing is one of the key pre-processing steps. In existing technologies, the cutting of metal tubing used in handlebar switch assemblies typically employs a single cutting device for either flat or bevel cutting of the ends. This makes it difficult to simultaneously meet the processing requirements of different end shapes in a single feed. For example, some applications require one end of the tubing to be flat and the other beveled to accommodate subsequent welding or assembly processes. However, traditional cutting equipment often can only achieve a single type of cut, requiring multiple feeds, which not only reduces production efficiency but also easily leads to decreased cutting accuracy due to repeated positioning errors.

[0003] Furthermore, existing devices often fail to automatically adjust the orientation of pipe fittings to the direction required for subsequent processes after cutting, necessitating manual intervention or additional flipping mechanisms, which increases equipment complexity and labor costs. Therefore, there is an urgent need for a cutting device capable of performing different types of cutting at both ends of pipe fittings on a single machine and automatically adjusting the orientation of the pipe fittings after cutting, in order to improve production efficiency and processing quality. Summary of the Invention

[0004] In order to overcome the above-mentioned defects of the prior art, the present invention provides a cutting device for a handlebar switch assembly to solve the problems existing in the background art.

[0005] This invention provides the following technical solution: a cutting device for a handlebar switch assembly, comprising a mounting frame, a conveying roller on the mounting frame, a receiving frame at the output end of the conveying roller, a first cutting mechanism and a second cutting mechanism mounted on the receiving frame, and a translation mechanism on the top of the receiving frame. The first cutting mechanism is used to perform a flat cut on one end of a metal pipe, and the second cutting mechanism is used to perform a bevel cut on the other end of the metal pipe. The translation mechanism is used to drive the receiving frame and the first and second cutting mechanisms thereon to move in a straight line so as to continuously complete the cutting processing of different forms at both ends of the pipe in the same process.

[0006] Preferably, the first cutting mechanism includes a first support frame and a first guide bucket. The first support frame is fixedly installed on the receiving frame, and a first rotating shaft is rotatably installed on the first support frame. A first blade is fixedly connected to the surface of the first rotating shaft.

[0007] Preferably, the first guide bucket and the receiving frame are fixedly connected by a stabilizing frame, the first motor is fixedly installed on the first support frame, and a power transmission component is provided between the output end of the first motor and the first rotating shaft.

[0008] Preferably, the second cutting mechanism includes a second support frame, a second guide bucket, and a positioning frame. The second support frame is fixedly installed on the receiving frame, and a second rotating shaft is rotatably installed on the second support frame. A second blade is fixedly connected to the surface of the second rotating shaft.

[0009] Preferably, a second motor is fixedly installed on the second support frame, a power transmission component is provided between the output end of the second motor and the second rotating shaft, and the connecting frame is fixedly installed on the receiving frame.

[0010] Preferably, a rotating shaft is rotatably mounted on the connecting frame, and an extension block and a cover plate are fixedly connected to the second guide bucket. The second guide bucket is fixedly mounted on the surface of the rotating shaft through the extension block.

[0011] Preferably, the connecting frame has a through hole, a guide rod is fixedly connected in the through hole, a movable block is sleeved on the surface of the guide rod, a crank and a connecting rod are provided between the movable block and the rotating shaft, one end of the crank is fixedly connected to one end of the rotating shaft, the other end of the crank is hinged to one end of the connecting rod, and the other end of the connecting rod is hinged to the movable block.

[0012] Preferably, a compression spring is sleeved on the surface of the guide rod, an L-shaped rod is fixedly connected to the movable block, and a roller is rotatably installed at the bottom end of the L-shaped rod.

[0013] Preferably, the positioning frame is fixedly installed on the mounting frame, and the positioning frame is provided with a triggering inclined surface, and the roller matches the triggering inclined surface.

[0014] Preferably, the translation mechanism includes a limiting shell, a sliding groove is provided inside the limiting shell, a threaded rod is rotatably installed in the sliding groove, a power device for driving the threaded rod to rotate is fixedly installed outside the limiting shell, a hook frame is fixedly connected to the top of the receiving frame, a sliding block is fixedly connected to the top of the hook frame, the sliding block is slidably installed in the sliding groove, and the sliding block is threadedly installed on the surface of the threaded rod.

[0015] The beneficial effects of this invention are: In this invention, by integrating a first cutting mechanism and a second cutting mechanism on the same receiving frame, and coordinating with a translation mechanism to drive the overall movement, the cutting of metal pipe fittings with different forms of flat and beveled ends can be completed continuously in one process, significantly improving production efficiency. Furthermore, since the cutting of both ends of the pipe fitting is completed under the same positioning reference, the accumulation of positioning errors between different processes is eliminated, thereby significantly improving the dimensional accuracy, angle consistency, and bevel shape stability of the cut end face, helping to ensure the quality of subsequent welding or assembly. In addition, this invention utilizes a linkage flipping structure in the second cutting mechanism to automatically complete the flipping action of the second guide bucket through mechanical triggering while the receiving frame is translating and cutting. This eliminates the need for additional control components such as sensors, cylinders, or independent motors, reducing not only the electrical complexity and manufacturing cost of the equipment but also potential failure points and maintenance workload. This flipping action automatically adjusts pipe fittings from a "flat front, beveled rear" position after cutting to a standard "beveled front, flat rear" position, ensuring they are smoothly fed into subsequent production equipment with a uniform orientation. This completely eliminates the need for manual material flipping and orientation adjustment, effectively preventing posture errors or product damage caused by improper human operation, and improving the automation level and operational reliability of the entire production line. Furthermore, the translation mechanism employs a precision transmission structure of threaded rods and sliding blocks, enabling precise control of the receiving frame's travel distance, ensuring consistent feed rates for each cut, and thus guaranteeing highly consistent cutting quality for all products in mass production. This invention offers significant advantages in improving cutting efficiency, ensuring processing accuracy, simplifying equipment structure, reducing manufacturing and maintenance costs, minimizing manual intervention, and enhancing automation levels. It is particularly suitable for mass production scenarios with specific requirements for pipe end shapes, such as vehicle handlebar switch assemblies. Attached Figure Description

[0027] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0028] Reference Figures 1 to 3 This invention provides a cutting device for a handlebar switch assembly, including a mounting frame 1, a conveying roller 2 on the mounting frame 1, a receiving frame 3 at the output end of the conveying roller 2, a first cutting mechanism 4 and a second cutting mechanism 5 mounted on the receiving frame 3, and a translation mechanism 6 on the top of the receiving frame 3. The first cutting mechanism 4 is used to perform a flat cut on one end of a metal pipe, and the second cutting mechanism 5 is used to perform a bevel cut on the other end of the metal pipe. The translation mechanism 6 is used to drive the receiving frame 3 and the first cutting mechanism 4 and the second cutting mechanism 5 on it to move in a straight line so as to continuously complete the cutting processing of different forms at both ends of the pipe in the same process.

[0029] Reference Figures 1 to 4The first cutting mechanism 4 includes a first support frame 41 and a first guide bucket 43. The first support frame 41 is fixedly installed on the receiving frame 3. A first rotating shaft 411 is rotatably installed on the first support frame 41. A first blade 45 is fixedly connected to the surface of the first rotating shaft 411. The first blade 45 is arranged vertically. The first guide bucket 43 and the receiving frame 3 are fixedly connected by a stabilizing frame 42. A first motor 44 is fixedly installed on the first support frame 41. A power transmission component is provided between the output end of the first motor 44 and the first rotating shaft 411.

[0030] In use, the first motor 44 drives the first rotating shaft 411 to rotate around its own axis through the power transmission component. The rotation of the first rotating shaft 411 drives the first blade 45 to rotate synchronously around the axis of the first rotating shaft 411. The first blade 45 gradually moves towards the metal tube. After the first blade 45 passes through the metal tube, the end of the metal tube is cut into a pipe fitting with a beveled front end and a flat rear end. The first guide bucket 43 catches the pipe fitting and the pipe fitting falls into the first guide bucket 43. Under the guidance of the first guide bucket 43, the pipe fitting maintains the posture of a beveled front end and a flat rear end as it enters the subsequent production and processing equipment.

[0031] In summary, the first cutting mechanism 4, by vertically arranging the first blade 45 and cooperating with the fixed installation of the first guide bucket 43, can directly receive the pipe fitting after one cutting action, and use its guiding effect to make the pipe fitting stably enter the subsequent production equipment in the standard posture of "beveled front end and flat rear end", without the need for additional manual posture adjustment, reducing auxiliary operation time and manual intervention costs. In addition, the first motor 44 drives the first rotating shaft 411 to rotate the first blade 45 through the power transmission component, realizing stable cutting of the flat end of the metal pipe, which helps to ensure the end face perpendicularity and flatness required for subsequent welding or assembly, thereby improving the overall manufacturing quality of the handlebar switch assembly.

[0032] Reference Figures 1 to 8 The second cutting mechanism 5 includes a second support frame 51, a second guide bucket 53, and a positioning frame 59. The second support frame 51 is fixedly mounted on the receiving frame 3. A second rotating shaft 511 is rotatably mounted on the second support frame 51. A second blade 55 is fixedly connected to the surface of the second rotating shaft 511. The second blade 55 is arranged at an angle. A second motor 54 is fixedly mounted on the second support frame 51. A power transmission component is provided between the output end of the second motor 54 and the second rotating shaft 511. A connecting frame 52 is fixedly mounted on the receiving frame 3. By arranging the second blade 55 at an angle and integrating it on the same receiving frame 3, the beveling of the metal tube end can be completed in one go by the translation of the receiving frame 3, without the need to adjust the blade angle separately or change the work position. This significantly improves the efficiency and angle consistency of beveling, and helps to ensure the beveling quality of subsequent welding or assembly.

[0033] A rotating shaft 56 is rotatably mounted on the connecting frame 52. An extension block 531 and a cover plate 532 are fixedly connected to the second guide bucket 53. The second guide bucket 53 is fixedly mounted on the surface of the rotating shaft 56 through the extension block 531. A through hole 521 is provided on the connecting frame 52. A guide rod 583 is fixedly connected in the through hole 521. A movable block 581 is sleeved on the surface of the guide rod 583. A crank 57 and a connecting rod 58 are provided between the movable block 581 and the rotating shaft 56. One end of the crank 57 is fixedly connected to one end of the rotating shaft 56. The other end of the crank 57 is hinged to one end of the connecting rod 58. The other end of the connecting rod 58 is hinged to the movable block 581. A compression spring 584 is sleeved on the surface of the guide rod 583. An L-shaped rod 582 is fixedly connected to the movable block 581. A roller 585 is rotatably mounted on the bottom end of the L-shaped rod 582. The mechanical linkage structure consisting of crank 57, connecting rod 58, movable block 581 and compression spring 584 can automatically drive the rotating shaft 56 to rotate the second guide bucket 53 when the receiving frame 3 moves by releasing or compressing the elastic force of the compression spring 584. No additional electrical control components are required, which simplifies the equipment structure, reduces manufacturing costs and failure rate, and ensures precise synchronization between the rotation action and the cutting stroke.

[0034] The positioning frame 59 is fixedly installed on the mounting frame 1. The positioning frame 59 is provided with a triggering inclined surface 591, and the roller 585 matches the triggering inclined surface 591. Through the rolling cooperation between the triggering inclined surface 591 on the positioning frame 59 and the roller 585, the flipping action of the second guide bucket 53 can be precisely triggered during the translation of the receiving frame 3, ensuring the consistency of the posture adjustment of each pipe.

[0035] In use, the second motor 54 drives the second rotating shaft 511 to rotate around its own axis through the power transmission component. The rotation of the second rotating shaft 511 drives the second blade 55 to rotate synchronously around the axis of the second rotating shaft 511. The second blade 55 gradually moves towards the metal tube. During this process, the roller 585 rolls along the triggering inclined surface 591, and the elastic force of the compression spring 584 is gradually released. The elastic force of the compression spring 584 drives the L-shaped rod 582 and the movable block 581 to slide along the guide rod 583 as a whole. The movable block 581 moves and drives the crank 57 to rotate synchronously around the axis of the rotating shaft 56 through the connecting rod 58. The rotating shaft 56 rotates synchronously around its own axis. The rotation of the rotating shaft 56 drives the second guide bucket 53 to rotate synchronously around the axis of the rotating shaft 56. When the second blade 55 just passes through the metal tube, the end of the metal tube is cut into a tube with a flat front end and a beveled rear end. The second guide bucket 53 just catches the tube and the tube falls into the second guide bucket 53. As the first blade 45 moves toward the metal tube, the roller 585 rolls along the triggering inclined surface 591, which squeezes the roller 585. Under the squeezing action, the movable block 581 overcomes the elastic force of the compression spring 584 and slides along the guide rod 583. The movement of the movable block 581 drives the crank 57 to rotate synchronously around the axis of the rotating shaft 56 through the connecting rod 58. The rotating shaft 56 rotates synchronously around its own axis. The rotation of the rotating shaft 56 drives the second guide bucket 53 to rotate synchronously around the axis of the rotating shaft 56. The second guide bucket 53 completes the flipping. After flipping, the tube in the second guide bucket 53 changes from a front flat end and a rear beveled end to a front beveled end and a rear flat end. Under the guidance of the second guide bucket 53, the tube maintains the front beveled end and rear flat end posture and enters the subsequent production and processing equipment.

[0036] In summary, the second cutting mechanism 5, by arranging the second blade 55 at an angle and cooperating with the reversible second guide bucket 53, can automatically drive the rotating shaft 56 to rotate and cause the second guide bucket 53 to flip while the receiving frame 3 is translating and cutting. This is achieved through the mechanical linkage between the roller 585 and the triggering inclined surface 591 on the positioning frame 59. No additional electrical control components such as sensors, cylinders, or independent motors are required, thus significantly reducing the electrical complexity and manufacturing cost of the equipment, and minimizing potential failure points and maintenance workload. Simultaneously, this flipping action can automatically adjust the pipe fitting, which is in a "flat front end, beveled rear end" posture after cutting, to a standard "beveled front end, flat rear end" posture, and achieve a unified... The stably oriented material is fed into subsequent production equipment, eliminating the need for manual turning or orientation adjustment. This avoids posture errors or product damage caused by improper human operation, improving the automation level and operational reliability of the entire production line. In addition, the linkage structure consisting of the guide rod 583, compression spring 584, movable block 581, crank 57, and connecting rod 58 on the connecting frame 52, in conjunction with the rolling action of the L-shaped rod 582 and roller 585, ensures precise synchronization between the turning action and the cutting stroke. Furthermore, the smooth and reliable release and compression process of the compression spring 584 ensures the consistency of posture adjustment for each pipe in batch production, which helps improve the quality stability of subsequent welding or assembly.

[0037] Reference Figures 1 to 9 The translation mechanism 6 includes a limiting shell 61, a sliding groove 62 is provided inside the limiting shell 61, a threaded rod 63 is rotatably installed in the sliding groove 62, and a power device for driving the threaded rod 63 to rotate is fixedly installed outside the limiting shell 61. A hook frame 64 is fixedly connected to the top of the receiving frame 3, and a sliding block 65 is fixedly connected to the top of the hook frame 64. The sliding block 65 is slidably installed in the sliding groove 62 and threadedly installed on the surface of the threaded rod 63.

[0038] In use, the power equipment drives the threaded rod 63 to rotate around its own axis. The rotation of the threaded rod 63 drives the sliding block 65, the hook frame 64 and the receiving frame 3 to slide synchronously along the sliding groove 62. The movement of the receiving frame 3 drives the first cutting mechanism 4 and the second cutting mechanism 5 to move synchronously in a straight line.

[0039] In summary, the translation mechanism 6, through the use of a precision screw transmission structure consisting of a sliding groove 62, a threaded rod 63, and a sliding block 65 within the limiting shell 61, and in conjunction with the hook frame 64, stably connects the receiving frame 3. This allows for precise control of the linear travel of the receiving frame 3, ensuring consistency of the feed amount and repeatability of the positioning accuracy for each cut. Consequently, in mass production, it guarantees a high degree of uniformity in the dimensional tolerances of the cutting positions at both ends of all pipe fittings. Simultaneously, the direction of movement of the receiving frame 3 can be easily adjusted by controlling the forward and reverse rotation of the threaded rod 63 through a power device, enabling the first cutting mechanism 4 and the second cutting mechanism 5 to sequentially perform different forms of cutting processes in the same operation.

[0040] The working principle of this invention is as follows: The conveying roller 2 conveys the metal tube. When the metal tube reaches the preset position, the power device drives the threaded rod 63 to rotate around its own axis. The rotation of the threaded rod 63 drives the sliding block 65, the hook frame 64 and the receiving frame 3 to slide synchronously along the sliding groove 62. The movement of the receiving frame 3 drives the first cutting mechanism 4 and the second cutting mechanism 5 to move synchronously. At the same time, the second motor 54 drives the second rotating shaft 511 to rotate around its own axis through the power transmission component. The rotation of the second rotating shaft 511 drives the second blade 55 to rotate synchronously around the axis of the second rotating shaft 511.

[0041] The second blade 55 gradually moves towards the metal tube. During this process, the roller 585 rolls along the triggering inclined surface 591, and the elastic force of the compression spring 584 is gradually released. The elastic force of the compression spring 584 drives the L-shaped rod 582 and the movable block 581 to slide along the guide rod 583 as a whole. The movable block 581 moves and drives the crank 57 to rotate synchronously around the axis of the rotating shaft 56 through the connecting rod 58. The rotating shaft 56 rotates synchronously around its own axis. The rotating shaft 56 rotates and drives the second guide bucket 53 to rotate synchronously around the axis of the rotating shaft 56. When the second blade 55 just passes through the metal tube, the end of the metal tube is cut into a tube with a flat front end and a beveled rear end. The second guide bucket 53 just catches the tube and the tube falls into the second guide bucket 53.

[0042] Afterwards, the power equipment drives the threaded rod 63 to rotate in the opposite direction around its own axis. Similarly, the receiving frame 3 drives the first cutting mechanism 4 and the second cutting mechanism 5 to move in the opposite direction as a whole. The conveying roller 2 then conveys the metal tube to the preset position. At the same time, the first motor 44 drives the first rotating shaft 411 to rotate around its own axis through the power transmission component. The first rotating shaft 411 rotates and drives the first blade 45 to rotate synchronously around the axis of the first rotating shaft 411. The first blade 45 gradually moves towards the direction of the metal tube. When the first blade 45 passes through the metal tube, the end of the metal tube is cut into a pipe with a beveled front end and a flat rear end. The first guide bucket 43 just catches the pipe. The pipe falls into the first guide bucket 43. Under the guidance of the first guide bucket 43, the pipe maintains the posture of a beveled front end and a flat rear end and enters the subsequent production and processing equipment.

[0043] As the first blade 45 moves toward the metal tube, the roller 585 rolls along the triggering inclined surface 591, which squeezes the roller 585. Under the squeezing action, the movable block 581 overcomes the elastic force of the compression spring 584 and slides along the guide rod 583. The movement of the movable block 581 drives the crank 57 to rotate synchronously around the axis of the rotating shaft 56 through the connecting rod 58. The rotating shaft 56 rotates synchronously around its own axis. The rotation of the rotating shaft 56 drives the second guide bucket 53 to rotate synchronously around the axis of the rotating shaft 56. The second guide bucket 53 completes the flipping. After flipping, the tube in the second guide bucket 53 changes from a front flat end and a rear beveled end to a front beveled end and a rear flat end. Under the guidance of the second guide bucket 53, the tube maintains the front beveled end and rear flat end posture and enters the subsequent production and processing equipment.

Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
