Description

Technical Field

[0001] This invention relates to the field of bicycle parts processing technology, specifically a cutting machine for processing bicycle parts. Background Technology

[0002] Bicycles consist of numerous components, including the frame, tires, pedals, fork assembly, chain, and freewheel. These components vary in shape, size, and material, requiring different types and performance cutting machines for processing. For example, cutting frame tubing requires precise control of the cutting angle and length, while cutting parts like the freewheel may demand higher surface quality and precision. To ensure bicycle performance and safety, the processing precision requirements for components are constantly increasing. Cutting machines need higher positioning accuracy, cutting accuracy, and repeatability to ensure dimensional and assembly accuracy of parts. As competition in the bicycle market intensifies, manufacturers need to improve production efficiency to reduce costs and enhance market competitiveness. High-efficiency cutting machines can complete the cutting of a large number of parts in a short time, reducing processing time and production costs.

[0003] When cutting bicycle frame tubing, if the diameter of the tubing is larger than the clamping range of the fixture, the fixture needs to be replaced to clamp and fix the tubing, which causes inconvenience in the process. Summary of the Invention

[0004] To achieve the above objectives, the present invention provides the following technical solution: a cutting machine for processing bicycle parts, comprising:

[0005] A workbench, wherein a cutting component is fixedly connected to the center of the top of the workbench, and a collecting component is fixedly connected to the inner side of the center of the workbench;

[0006] A clamping component is used to clamp the pipe fitting. The clamping components are symmetrically arranged on both sides of the top of the workbench, and the bottom of the clamping components is fixedly connected to the top of the workbench.

[0007] The clamping component includes a clamping frame, the bottom of which is fixedly connected to the top of the workbench. A clamping plate is slidably connected to the inner side of the clamping frame. An arc-shaped plate is fixedly connected to the side of the clamping plate near the cutting component. An electric hydraulic cylinder is fixedly connected to the side of the clamping frame, and the output end of the electric hydraulic cylinder is fixedly connected to the side of the clamping plate.

[0008] Meanwhile, when the diameter of the pipe fitting exceeds the clamping range of the clamping frame, the side of the pipe fitting is brought into contact with the arc-shaped plate located at the bottom of the inner cavity of the clamping frame. By activating the electric hydraulic cylinder, the output end of the electric hydraulic cylinder drives the arc-shaped plate to move towards the inner wall of the pipe fitting through the clamping plate, so that the clamping plate and the arc-shaped plate are brought into contact with the inner wall of the pipe fitting for a stop, thereby clamping and fixing the pipe fitting.

[0009] Preferably, the collecting component includes a collecting box, the side of which is fixedly connected to the inside of the workbench, a mesh plate is fixedly connected to the top of the collecting box, an air suction mechanism is fixedly connected to the bottom of the inner cavity of the collecting box, a moving mechanism is slidably connected to the bottom of the mesh plate, and a filtering mechanism is fixedly connected to both sides of the collecting box.

[0010] When cutting pipe fittings, the suction mechanism is activated, and the suction force generated by the suction mechanism is used to collect the debris and exhaust gas generated during the cutting process through the mesh plate into the collection box. At the same time, the suction force of the suction mechanism causes the moving mechanism to move downward, and the filter mechanisms on both sides are activated to filter the exhaust gas generated during the cutting process.

[0011] Preferably, the moving mechanism includes a sliding rod and a base plate. The side of the base plate is fixedly connected to the inside of the collection box. The top of the sliding rod is slidably connected to the bottom of the mesh plate. A contact component is fixedly connected to the bottom of the sliding rod. A first spring is sleeved on the sliding rod. The top of the first spring is fixedly connected to the bottom of the mesh plate. The bottom of the first spring is fixedly connected to the top of the contact frame.

[0012] By activating the suction mechanism, the suction force generated during its operation causes the contact component to pull the first spring and sliding rod downwards. Simultaneously, the contact component moves on the base plate, thereby preventing the processing waste entering the collection box from accumulating in a large amount on one part of the base plate, which would otherwise cause uneven waste collection.

[0013] Preferably, the contact assembly includes a contact frame, the top of which is fixedly connected to the bottom of the sliding rod, a connecting seat is fixedly connected to the middle of the bottom of the contact frame, connecting rods are rotatably connected to both sides of the middle of the connecting seat, a push plate is rotatably connected to the end of the connecting rod away from the connecting seat, and the bottom of the push plate is slidably connected to the top of the base plate.

[0014] After the cutting work is completed, the suction mechanism stops working, and the contact frame moves upward and resets through the sliding rod driven by the reset of the first spring. At the same time, the contact frame drives the push plate through the connecting rod to move on the bottom of the base plate, thereby evenly dispersing the impurities accumulated on the top of the base plate.

[0015] Preferably, the filtration mechanism includes a filter housing, an interception housing fixedly connected to the inner side of the filter housing, the side of the interception housing away from the motor fixedly connected to the inner side of the workbench, a filter screen fixedly connected to the side of the interception housing near the workbench, a mesh frame fixedly connected to the side of the interception housing away from the filter screen, a motor fixedly connected to the side of the mesh frame, an exhaust assembly fixedly connected to the middle of the inner cavity of the interception housing, filter boxes fixedly connected to both sides of the exhaust assembly, a spiral shaft rotatably connected to the side of the mesh frame away from the motor, the other end of the spiral shaft rotatably connected to the side of the filter screen, the side of the spiral shaft away from the filter screen fixedly connected to the output end of the motor, and a blocking assembly fixedly connected to the inner side of the interception housing.

[0016] When cutting pipe fittings, the suction mechanism is activated, and the suction force of the suction mechanism draws impurities and exhaust gas into the collection box. At the same time, the exhaust assembly is activated, and the suction force of the exhaust assembly is greater than that of the suction mechanism, so the exhaust gas is drawn into the filter housing through the exhaust assembly.

[0017] Preferably, the blocking assembly includes a blocking plate, the side of which is fixedly connected to the inner side of the intercepting shell, a sliding rod slidably connected to the bottom of the blocking plate, an arc plate fixedly connected to the bottom of the sliding rod, the side of the arc plate slidably connected to the inner side of the filter shell and the intercepting shell, a second spring sleeved on the sliding rod, the top of the second spring fixedly connected to the bottom of the blocking plate, and the bottom of the second spring fixedly connected to the top of the arc plate;

[0018] Preferably, during the exhaust gas filtration process, the suction force generated by the exhaust assembly causes the arc plate to move upward by pulling the second spring slide rod and abut against the inner side of the interceptor housing, forming an effective barrier. This prevents impurities in the inner cavity of the filter housing from being sucked into the interceptor housing, ensuring the cleanliness of the interceptor housing and preventing impurities from accumulating inside the interceptor housing and affecting the normal operation of the equipment.

[0019] This invention provides a cutting machine for processing bicycle parts. It has the following advantages:

[0020] 1. This cutting machine for processing bicycle parts is equipped with a clamping component, which can effectively clamp pipes of standard diameter by having the side of the pipe abut against the clamping plate and the electric hydraulic cylinder driving the arc plate to clamp and fix it; it can also use different clamping methods for pipes with diameters exceeding the normal clamping range of the clamping frame, that is, fixing them by having the arc plate abut against the inner wall of the pipe to limit the movement, thus adapting to the processing needs of pipes of various sizes and specifications.

[0021] 2. This bicycle parts processing cutting machine is equipped with a moving mechanism that moves the push plate from the top of the base plate to both sides during the impurity collection process. This mechanism can promptly and evenly disperse the fallen impurities, preventing them from accumulating in a certain part of the base plate. This makes the impurities more evenly distributed on the base plate, facilitating subsequent unified collection and processing, and improving the efficiency and quality of impurity collection.

[0022] 3. The bicycle parts processing cutting machine is equipped with a contact component. After the cutting work is completed, the device can use the reset of the first spring to drive the push plate to evenly disperse the impurities accumulated on the top of the base plate. No manual operation is required, saving labor costs and improving work efficiency.

[0023] 4. This bicycle parts processing cutting machine is equipped with a filtration mechanism. It uses activated carbon particles to adsorb and filter the exhaust gas, which can effectively remove harmful substances from the exhaust gas, thereby realizing resource recycling and environmental protection.

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] See also Figures 1-3 This invention provides a technical solution: a cutting machine for processing bicycle parts, comprising:

[0035] Workbench 1, with a cutting component 2 fixedly connected to the middle of the top of workbench 1, and a collecting component 4 fixedly connected to the inner side of the middle of workbench 1;

[0036] Clamping component 3 is used to clamp the pipe fitting. The clamping component 3 is symmetrically arranged on both sides of the top of the workbench 1, and the bottom of the clamping component 3 is fixedly connected to the top of the workbench 1.

[0037] The clamping component 3 includes a clamping frame 31, the bottom of which is fixedly connected to the top of the workbench 1. A clamping plate 32 is slidably connected to the inner side of the clamping frame 31. An arc-shaped plate 34 is fixedly connected to the side of the clamping plate 32 near the cutting component 2. An electric hydraulic cylinder 33 is fixedly connected to the side of the clamping frame 31. The output end of the electric hydraulic cylinder 33 is fixedly connected to the side of the clamping plate 32.

[0038] By placing the pipe fitting in the middle of the clamping frame 31, and by abutting the side of the pipe fitting against the clamping plate 32 located at the bottom of the inner cavity of the clamping frame 31, the electric hydraulic cylinders 33 on both sides are activated, and the output end of the electric hydraulic cylinders 33 drives the arc plate 34 to clamp and move towards the pipe fitting, thereby clamping and fixing the pipe fitting.

[0039] Meanwhile, when the diameter of the pipe being processed exceeds the clamping range of the clamping frame 31, the side of the pipe is brought into contact with the arc plate 34 located at the bottom of the inner cavity of the clamping frame 31. By activating the electric hydraulic cylinder 33, the output end of the electric hydraulic cylinder 33 drives the arc plate 34 to move towards the inner wall of the pipe through the clamping plate 32, so that the clamping plate 32 drives the arc plate 34 to abut against the inner wall of the pipe for a limiting position, thereby clamping and fixing the pipe.

[0040] See also Figures 1-4 The present invention provides a technical solution: the collection component 4 includes a collection box 41, the side of the collection box 41 is fixedly connected to the inner side of the workbench 1, the top of the collection box 41 is fixedly connected to a mesh plate 42, the bottom of the inner cavity of the collection box 41 is fixedly connected to an air suction mechanism 44, the bottom of the mesh plate 42 is slidably connected to a moving mechanism 43, and both sides of the collection box 41 are fixedly connected to a filtering mechanism 45.

[0041] When cutting pipe fittings, the suction mechanism 44 is turned on. The suction generated by the suction mechanism 44 is used to collect the debris and exhaust gas generated during the cutting process through the mesh plate 42 into the collection box 41. At the same time, the suction of the suction mechanism 44 causes the moving mechanism 43 to move downward. Meanwhile, the filter mechanisms 45 on both sides are turned on to filter the exhaust gas generated during the cutting process.

[0042] See also Figure 1-Figure 5 The moving mechanism 43 includes a sliding rod 432 and a base plate 434. The side of the base plate 434 is fixedly connected to the inside of the collection box 41. The top of the sliding rod 432 is slidably connected to the bottom of the mesh plate 42. A contact component 431 is fixedly connected to the bottom of the sliding rod 432. A first spring 433 is sleeved on the sliding rod 432. The top of the first spring 433 is fixedly connected to the bottom of the mesh plate 42. The bottom of the first spring 433 is fixedly connected to the top of the contact frame 4311.

[0043] By activating the suction mechanism 44, the suction force generated by the suction mechanism 44 during operation causes the contact component 431 to pull the first spring 433 and the sliding rod 432 downward. At the same time, the contact component 431 moves on the base plate 434, thereby preventing the processing waste entering the collection box 41 from accumulating in a large amount in one part of the base plate 434, thus causing uneven waste collection.

[0044] See also Figures 1-6The contact assembly 431 includes a contact frame 4311, the top of which is fixedly connected to the bottom of a sliding rod 432. A connecting seat 4312 is fixedly connected to the middle of the bottom of the contact frame 4311. A connecting rod 4313 is rotatably connected to both sides of the middle of the connecting seat 4312. A push plate 4314 is rotatably connected to the end of the connecting rod 4313 away from the connecting seat 4312. The bottom of the push plate 4314 is slidably connected to the top of the base plate 434.

[0045] The suction force of the suction mechanism 44 causes the contact frame 4311 to move the connecting seat 4312 downward. At the same time, the contact frame 4311 pulls the first spring 433 and the sliding rod 432 downward. Simultaneously, the contact frame 4311, through the connecting seat 4312 and the connecting rod 4313, drives the push plate 4314 to move from the top of the base plate 434 to both sides of the base plate 434. This prevents impurities from falling onto the base plate 434 and accumulating in one part of the base plate 434 during collection, thus causing uneven dispersion of impurities.

[0046] When the cutting work is completed, the suction mechanism 44 stops working. The contact frame 4311 is driven by the reset of the first spring 433 and moves upward through the sliding rod 432 to reset. At the same time, the contact frame 4311 drives the push plate 4314 through the connecting rod 4313 to move on the bottom of the base plate 434, thereby uniformly dispersing the impurities accumulated on the top of the base plate 434.

[0047] See also Figures 1-7 The filtration mechanism 45 includes a filter housing 451, an interception housing 459 fixedly connected to the inner side of the filter housing 451, the side of the interception housing 459 away from the motor 454 fixedly connected to the inner side of the workbench 1, a filter screen 452 fixedly connected to the side of the interception housing 459 close to the workbench 1, a mesh frame 453 fixedly connected to the side of the interception housing 459 away from the filter screen 452, a motor 454 fixedly connected to the side of the mesh frame 453, an exhaust assembly 455 fixedly connected to the middle of the inner cavity of the interception housing 459, a filter box 456 fixedly connected to both sides of the exhaust assembly 455, a spiral shaft 457 rotatably connected to the side of the mesh frame 453 away from the motor 454, the other end of the spiral shaft 457 rotatably connected to the side of the filter screen 452, and the side of the spiral shaft 457 away from the filter screen 452 fixedly connected to the output end of the motor 454. A blocking assembly 458 is fixedly connected to the inner side of the interception housing 459.

[0048] When cutting the pipe fittings, the suction mechanism 44 is turned on, and the suction force of the suction mechanism 44 is used to draw impurities and exhaust gas into the collection box 41. At the same time, the exhaust assembly 455 is turned on, and the suction force of the exhaust assembly 455 is greater than that of the suction mechanism 44, so the exhaust gas is drawn into the filter housing 451 through the exhaust assembly 455.

[0049] By placing activated carbon particles on both sides of the inner cavity of the filter housing 451, and simultaneously turning on the motor 454, the output end of the motor 454 drives the spiral shaft 457 to rotate in the filter housing 451. This allows the spiral shaft 457 to drive the activated carbon particles to fully contact the exhaust gas when it enters the filter housing 451, thus enabling the activated carbon particles to better filter and adsorb the exhaust gas. At the same time, through the continuous suction of the exhaust component 455, the exhaust gas filtered by the activated carbon particles continues to pass through the filter box 456 for secondary filtration. The filtered exhaust gas is then discharged through the mesh frame 453.

[0050] See also Figures 1-8 The blocking assembly 458 includes a blocking plate 4581, the side of the blocking plate 4581 is fixedly connected to the inner side of the interception housing 459, a sliding rod 4582 is slidably connected to the bottom of the blocking plate 4581, an arc plate 4583 is fixedly connected to the bottom of the sliding rod 4582, the side of the arc plate 4583 is slidably connected to the inner side of the filter housing 451 and the interception housing 459, a second spring 4584 is sleeved on the sliding rod 4582, the top of the second spring 4584 is fixedly connected to the bottom of the blocking plate 4581, and the bottom of the second spring 4584 is fixedly connected to the top of the arc plate 4583;

[0051] When the activated carbon particles are in full contact with the exhaust gas for adsorption, large particulate impurities in the exhaust gas will remain inside the filter housing 451. After the exhaust gas is filtered, the baffle 4581 moves downward by the reset pull of the second spring 4584 when the exhaust assembly 455 is closed, thereby disengaging from the filter housing 451 and the inside of the interceptor housing 459.

[0052] When the motor 454 is turned on, the output end of the motor 454 drives the spiral shaft 457 to rotate inside the filter housing 451, thereby fully agitating the activated carbon particles inside the filter housing 451. This allows large particles of impurities that are intercepted and adsorbed by the activated carbon particles to fall out of the inner cavity of the interception housing 459 through the baffle plate 4581. At the same time, by setting the arc plate 4583 to a shape that is high in the middle and low on both sides, the impurities that fall through the baffle plate 4581 can enter the bottom of the inner cavity of the filter housing 451 for collection.

[0053] During the exhaust gas filtration process, the suction force generated by the exhaust assembly 455 causes the arc plate 4583 to move upward by pulling the second spring 4584 and slide rod 4582, and abut against the inside of the interception shell 459, forming an effective barrier. This prevents impurities in the inner cavity of the filter shell 451 from being sucked into the interception shell 459, ensuring the cleanliness of the interception shell 459 and preventing impurities from accumulating inside the interception shell 459 and affecting the normal operation of the equipment.

[0054] Specific workflow:

[0055] Select suitable tubing as raw material for bicycle parts, and determine the processing range of the cutting machine and the size of the parts. At the same time, clean the surface of the material to remove oil, rust and other impurities to ensure cutting quality.

[0056] The two sides of the pipe fitting are fixed by the clamping components 3 on both sides of the top of the workbench 1. The pipe fitting is cut by opening the cutting component 2.

[0057] The cutting blade of cutting component 2 will automatically move to the starting position according to the instructions to position and calibrate the pipe. The position and posture of the pipe are identified and adjusted by the camera to ensure the accuracy of the cutting position.

[0058] At the same time, by activating the collection component 4, the debris and exhaust gas generated during pipe processing are collected and filtered.

[0059] Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art and related fields based on the embodiments of the present invention without inventive effort should fall within the scope of protection of the present invention. Structures, devices, and operating methods not specifically described and explained in the present invention, unless otherwise specified or limited, shall be implemented according to conventional means in the art.
