Description

Technical Field

[0001] The present invention relates to the technical field of bicycle parts processing, and specifically relates to a cutting machine for bicycle parts processing. Background Art

[0002] A bicycle consists of numerous parts, including a frame, tires, pedal components, front fork assemblies, chains, flywheels, etc. Different parts vary in shape, size, and material, and require different types and performance of cutting machines for processing. For example, the cutting of the frame tubes requires precise control of the cutting angle and length, while the cutting of parts such as flywheels may have higher requirements for surface quality and precision. To ensure the performance and safety of bicycles, the processing accuracy requirements for parts are getting higher and higher. The cutting machine needs to have higher positioning accuracy, cutting accuracy, and repeat accuracy to ensure the dimensional accuracy and assembly accuracy of the parts. With the increasing competition in the bicycle market, production enterprises need to improve production efficiency to reduce costs and enhance market competitiveness. An efficient cutting machine can complete the cutting of a large number of parts in a short time, reducing processing time and production costs.

[0003] When cutting the pipe fittings of a bicycle frame, when the diameter of the pipe fitting is larger than the clamping range of the fixture, the fixture needs to be replaced to clamp and fix the pipe fitting, which causes inconvenience in processing. Summary of the Invention

[0005] A workbench, in the middle of the top of the workbench, there is a fixedly connected cutting component, and in the inner side of the middle of the workbench, there is a fixedly connected collection component;

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

[0007] The clamping component includes a clamping frame, the bottom of the clamping frame is fixedly connected to the top of the workbench, the inner side of the clamping frame is slidably connected with a clamping plate, an arc-shaped plate is fixedly connected to the side of the clamping plate close to 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] At the same time, when the diameter of the processed pipe exceeds the clamping range of the clamping frame, the side of the pipe is abutted against the arc plate at the bottom of the inner cavity of the clamping frame, and the electric hydraulic cylinder is turned on. The output end of the electric hydraulic cylinder drives the arc plate to move toward the inner wall of the pipe through the clamping plate, so that the clamping plate drives the arc plate and the inner wall of the pipe to abut against each other and limit the position, thereby clamping and fixing the pipe;

[0010] When cutting the pipe fittings, the suction mechanism is turned on, and the suction force generated by the suction mechanism is used to collect the debris and waste gas generated during the cutting work into the collection box through the mesh plate.

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

[0014] When the cutting work is finished, the suction mechanism stops working, and the contact frame is driven by the reset of the first spring and moves upward through the sliding rod to reset.

[0016] When cutting the pipe fittings, by turning on the suction mechanism, through the suction work of the suction mechanism, impurities and waste gas are sucked into the collection box. At the same time, by turning on the exhaust assembly, and the suction of the exhaust assembly is greater than that of the suction mechanism, the waste gas is sucked into the filtering housing through the exhaust assembly;

[0018] Preferably, during the waste gas filtering process, due to the suction generated by the exhaust assembly, the arc plate slides upward by pulling the second spring and the sliding rod and abuts against the inner side of the intercepting housing, forming an effective barrier, which can prevent the impurities in the inner cavity of the filtering housing from being sucked into the intercepting housing, ensuring the cleanliness of the inside of the intercepting housing and preventing the accumulation of impurities in the intercepting housing from affecting the normal operation of the equipment.

Detailed implementation mode

[0033] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0034] Please refer to Figures 1 - 3 , the present invention provides a technical solution: a cutting machine for processing bicycle parts, including:

[0035] The workbench 1, the middle part of the top of the workbench 1 is fixedly connected with the cutting component 2, and the inner side of the middle part of the workbench 1 is fixedly connected with the collecting component 4;

[0036] The clamping component 3, which is used for clamping the pipe fittings. 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 with the top of the workbench 1;

[0037] The clamping component 3 includes a clamping frame 31, the bottom of the clamping frame 31 is fixedly connected with the top of the workbench 1, the inner side of the clamping frame 31 is slidably connected with a clamping plate 32, one side of the clamping plate 32 close to the cutting component 2 is fixedly connected with an arc plate 34, the side of the clamping frame 31 is fixedly connected with an electric hydraulic cylinder 33, and the output end of the electric hydraulic cylinder 33 is fixedly connected with the side of the clamping plate 32;

[0038] By placing the pipe fitting in the middle of the clamping frame 31, by making the side of the pipe fitting abut against the clamping plate 32 at the bottom of the inner cavity of the clamping frame 31, by turning on the electric hydraulic cylinders 33 on both sides, and by driving the arc plate 34 to move towards the pipe fitting for clamping by the output end of the electric hydraulic cylinder 33, the pipe fitting can be clamped and fixed;

[0039] Meanwhile, when the diameter of the pipe fitting to be processed exceeds the clamping range of the clamping frame 31, the side of the pipe fitting is abutted against the arc-shaped plate 34 located at the bottom of the inner cavity of the clamping frame 31. By turning on the electric hydraulic cylinder 33, the output end of the electric hydraulic cylinder 33 drives the arc-shaped plate 34 to move towards the inner wall of the pipe fitting through the clamping plate 32, so that the clamping plate 32 drives the arc-shaped plate 34 to abut against and limit the inner wall of the pipe fitting, thereby clamping and fixing the pipe fitting;

[0040] Please refer to 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, a net plate 42 is fixedly connected to the top of the collection box 41, a suction mechanism 44 is fixedly connected to the bottom of the inner cavity of the collection box 41, a moving mechanism 43 is slidably connected to the bottom of the net plate 42, and filtering mechanisms 45 are fixedly connected to both sides of the collection box 41;

[0041] When cutting the pipe fitting, by turning on the suction mechanism 44, the suction force generated when the suction mechanism 44 works is used to collect the debris and waste gas generated during the cutting work through the net plate 42 into the collection box 41. At the same time, due to the suction force of the suction mechanism 44, the moving mechanism 43 moves downward. At the same time, by turning on the filtering mechanisms 45 on both sides, the waste gas generated during the cutting work is filtered by the filtering mechanisms 45;

[0042] Please refer to Figures 1 - 5 , the moving mechanism 43 includes a sliding rod 432 and a bottom plate 434. The side of the bottom plate 434 is fixedly connected to the inner side of the collection box 41. The top of the sliding rod 432 is slidably connected to the bottom of the net 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 net plate 42, and the bottom of the first spring 433 is fixedly connected to the top of the contact frame 4311;

[0043] By turning on the suction mechanism 44, the suction force generated when the suction mechanism 44 works causes the contact component 431 to pull the first spring 433 and the sliding rod 432 to move downward. At the same time, the contact component 431 moves on the bottom plate 434, thereby preventing the processed waste chips entering the collection box 41 from accumulating in a large amount in one part of the bottom plate 434, thus causing the phenomenon of uneven waste chip collection;

[0044] Please refer to Figures 1 - 6, the contact component 431 includes a contact frame 4311. The top of the contact frame 4311 is fixedly connected to the bottom of the sliding rod 432. In the middle of the bottom of the contact frame 4311, a connecting seat 4312 is fixedly connected. On both sides of the middle of the connecting seat 4312, a connecting rod 4313 is rotatably connected. One end of the connecting rod 4313 away from the connecting seat 4312 is rotatably connected to a push plate 4314. The bottom of the push plate 4314 is slidably connected to the top of the bottom plate 434;

[0045] It works through the suction of the suction mechanism 44, so that the contact frame 4311 drives the connecting seat 4312 to move downward. At the same time, the contact frame 4311 pulls the first spring 433 and the sliding rod 432 to move downward. At the same time, the contact frame 4311 drives the push plate 4314 to move to both sides of the bottom plate 434 on the top of the bottom plate 434 through the connecting seat 4312 and the connecting rod 4313, so as to avoid the phenomenon that when impurities fall on the bottom plate 434 for collection work, the impurities will accumulate in one part of the bottom plate 434, resulting in uneven dispersion of the impurities;

[0046] When the cutting work is over, 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. At the same time, the contact frame 4311 drives the push plate 4314 through the connecting rod 4313 and moves on the bottom of the bottom plate 434, so as to evenly disperse the impurities accumulated on the top of the bottom plate 434;

[0047] Please refer to Figures 1 - 7 , the filtering mechanism 45 includes a filtering housing 451. Inside the filtering housing 451, an intercepting housing 459 is fixedly connected. One side of the intercepting housing 459 away from the motor 454 is fixedly connected to the inside of the workbench 1. One side of the intercepting housing 459 close to the workbench 1 is fixedly connected with a filter screen 452. One side of the intercepting housing 459 away from the filter screen 452 is fixedly connected with a wire mesh frame 453. A motor 454 is fixedly connected to the side of the wire mesh frame 453. In the middle of the inner cavity of the intercepting housing 459, an exhaust component 455 is fixedly connected. On both sides of the exhaust component 455, a filter box 456 is fixedly connected. One side of the wire mesh frame 453 away from the motor 454 is rotatably connected with a spiral shaft 457. The other end of the spiral shaft 457 is rotatably connected to the side of the filter screen 452. One side of the spiral shaft 457 away from the filter screen 452 is fixedly connected to the output end of the motor 454. An anti-blocking component 458 is fixedly connected to the inside of the intercepting housing 459;

[0048] When cutting the pipe fitting, by turning on the suction mechanism 44 and working through the suction of the suction mechanism 44, the impurities and waste gas are sucked into the collection box 41. At the same time, by turning on the exhaust component 455, and the suction of the exhaust component 455 is greater than the suction of the suction mechanism 44, the waste gas is sucked into the filtering housing 451 through the exhaust component 455;

[0049] By placing activated carbon particles on both sides of the inner cavity of the filtration housing 451, and at the same time turning on the motor 454, the output end of the motor 454 drives the spiral shaft 457 to rotate in the filtration housing 451. When the waste gas enters the filtration housing 451, the spiral shaft 457 drives the activated carbon particles to come into full contact with the waste gas, so that the activated carbon particles can better filter and adsorb the waste gas. At the same time, through the continuous suction of the exhaust assembly 455, the waste gas filtered by the activated carbon particles continuously passes through the filter box 456, and then the waste gas is secondarily filtered. The filtered waste gas is discharged through the wire mesh frame 453;

[0050] Please refer to Figures 1 - 8 As shown in the figure, 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 intercepting housing 459. A sliding rod 4582 is slidably connected to the bottom of the blocking plate 4581. The bottom of the sliding rod 4582 is fixedly connected to an arc plate 4583. The side of the arc plate 4583 is slidably connected to the inner sides of the filtration housing 451 and the intercepting 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. 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 and adsorption with the waste gas, large particle impurities in the waste gas will remain in the inner side of the filtration housing 451. After the waste gas filtration is completed, by turning off the exhaust assembly 455, the blocking plate 4581 moves downward under the reset pull of the second spring 4584, so as to disengage from the inner sides of the filtration housing 451 and the intercepting housing 459;

[0052] Turn on the motor 454, and the output end of the motor 454 drives the spiral shaft 457 to rotate in the inner side of the filtration housing 451, so as to fully stir the activated carbon particles in the inner side of the filtration housing 451, so that the large particle impurities intercepted and adsorbed by the activated carbon particles can fall out of the inner cavity of the intercepting housing 459 through the blocking plate 4581. At the same time, by setting the arc plate 4583 to be high in the middle and low on both sides, the impurities falling through the blocking plate 4581 can enter the bottom of the inner cavity of the filtration housing 451 for collection;

[0053] During the waste gas filtration process, due to the suction generated by the exhaust assembly 455, the arc plate 4583 slides upward through the second spring 4584 and the sliding rod 4582 and abuts against the inner side of the intercepting housing 459 to form an effective barrier, which can prevent the impurities in the inner cavity of the filtration housing 451 from being sucked into the intercepting housing 459, ensuring the cleanliness of the intercepting housing 459 and preventing the impurities from accumulating in the intercepting housing 459 and affecting the normal operation of the equipment.

[0054] Specific workflow:

[0055] Select appropriate pipe materials as raw materials for bicycle parts. According to the processing range of the cutting machine and the part size, at the same time, clean the surface of the materials to remove oil, rust and impurities to ensure the cutting quality;

[0056] Place both sides of the pipe fitting on the clamping components 3 on both sides of the top of the workbench 1 for fixation. By turning on the cutting component 2, the cutting component 2 performs cutting work on the pipe fitting;

[0057] The cutting blade of the cutting component 2 will automatically move to the starting position according to the instruction to position and calibrate the pipe fitting. The position and attitude of the pipe fitting are identified and adjusted through the camera to ensure the accuracy of the cutting position;

[0058] At the same time, by turning on the collection component 4, the collection component 4 collects and filters the debris and waste gas generated during the processing of the pipe fitting.

[0059] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art and related fields without creative efforts shall fall within the protection scope of the present invention.
