Description

Technical Field

[0001] This invention belongs to the field of electric bicycles, and in particular relates to a machining and debugging method for carbon fiber bicycle mounting holes and a method for using the machine. Background Technology

[0002] If all the shapes and assembly areas of a carbon fiber electric bicycle were molded, the fitting and molding process would be extremely complex, which would be detrimental to production operations and quality stability. Therefore, some parts of a carbon fiber electric bicycle are post-machined using a CNC / 5-axis machine. However, due to the characteristics of composite materials, the rough blank after molding will vary. The relative position from the motor mount to the head tube differs from the position on the design drawing by 1-2mm. Due to the deformation, the position that needs to be machined on the rough blank does not match the position on the drawing. Programmers and debuggers need to adjust the machine tool multiple times based on the actual variation value of the rough blank to find the correct machining position, and then modify the machining program. Each machining position needs to be repeatedly adjusted until the machining position is accurate, which requires a lot of programming, as shown in the table below.

[0003]

[0004] As shown in the table above, debugging one machining process takes 40 minutes. With an average of 25 processes per chassis, repeated debugging would take 1000 minutes, or 16.7 hours. Since it's impossible to complete all processes during the day shift, the fixtures and chassis cannot be removed for machining other models during the night shift, leaving the machine idle. The first machine requires two days and one night to complete debugging. Since the first machine is completed during the night shift, the remaining two need to be processed the following day. Therefore, the first round of verification machining will take two and a half days (plus two night shifts), with machine usage time: 22 + 22 + 4 = 48 hours. The machine utilization rate is extremely low. Summary of the Invention

[0010] Preferably, step S7, controlling the second tool to machine a plurality of the holes to be machined on the first rough blank structure according to the first revision program to form the mounting holes, includes: controlling the second tool to machine a plurality of the holes to be machined on the first rough blank structure according to the first revision program to form first machined holes; recording a first offset value between the position of the first machined hole and the actual required position of the mounting hole; revising the first revision program according to the first offset value and forming a second revision program; providing a second rough blank structure, the second rough blank structure being formed by the same process as the first rough blank structure; and controlling the second tool to machine a plurality of the holes to be machined on the second rough blank structure according to the second revision program to form the mounting holes.

[0011] Preferably, controlling the second tool to machine a plurality of holes to be machined on the second rough blank structure according to the second revision program to form the mounting holes includes: controlling the second tool to machine a plurality of holes to be machined on the second rough blank structure according to the second revision program to form second machined holes; recording a second offset value between the second machined holes and the mounting holes at the actual required positions; revising the second revision program according to the second offset value to form a third revision program; providing a third rough blank structure, the third rough blank structure being formed by the same process as the second rough blank structure; controlling the second tool to machine a plurality of holes to be machined on the third rough blank structure according to the third revision program to form third machined holes to verify the third revision program; recording a third offset value between the third machined holes and the mounting holes at the actual required positions, if the third offset value is less than a preset value, then no revision of the third revision program is required, if the third offset value is greater than the preset value, then repeating the aforementioned steps until the offset between the obtained machined holes and the mounting holes at the actual required positions is less than the preset value.

[0012] Preferably, in step S7, after controlling the second tool to machine the plurality of holes to be machined on the first rough blank structure to form the mounting holes according to the first revised program, the method further includes: performing physical property testing on the first rough blank structure, the physical property testing including strength testing and hardness testing.

[0013] This invention also provides a method for using a machine tool, the method comprising: S10, mounting a first rough blank structure of a carbon fiber bicycle and a first cutting tool on the machine tool, the first rough blank structure having a plurality of holes to be machined to form mounting holes, each of the holes to be machined having a tool-setting mold, the tool-setting mold being located in the middle of the hole to be machined, and the size of the working end of the first cutting tool being the same as the size of the tool-setting mold; S20, providing a first machining program for the machining position of the tool-setting mold according to the design drawing of the carbon fiber bicycle, and using the first machining program to control the first cutting tool to perform hole-making on all the tool-setting molds to form first tool-setting holes; S30, recording the offset between each first tool-setting hole and the corresponding tool-setting mold; S40, removing the first rough blank structure to process other carbon fiber bicycles.

[0016] Compared with the prior art, the present invention adds a die-setting mold in the middle of the hole to be processed. The first machining program can perform hole processing on all the die-setting molds at once and uniformly capture the offset. This eliminates the need to process only one hole at a time and to debug and verify the machining program after processing each hole. The offset value between the first die-setting hole and the die-setting mold is obtained by machining the die-setting mold. The offset value is then used to revise the second machining program to obtain the mounting hole at the required position. At the same time, since the offset between the hole processed by the revised first program and the actual required mounting hole is 0 or very small, it will not cause the first rough blank structure product to be directly scrapped. Even if there is a slight offset, the first rough blank structure product can still be used for other physical property tests and verifications. Attached Figure Description

[0017] Figure 1 This is a structural diagram of the first rough embryo structure according to an embodiment of the present invention.

[0018] Figure 2 for Figure 1 Enlarged view of point A in the middle. Detailed Implementation

[0019] To illustrate the technical content, structural features, and effects of the present invention in detail, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0020] like Figure 1 As shown, this embodiment of the invention provides a machining and adjustment method for carbon fiber bicycle mounting holes, the machining and adjustment method including the following steps:

[0021] S1. A first rough blank structure 10 for a carbon fiber bicycle is provided. The first rough blank structure 10 has a plurality of holes 1 to be machined to form the mounting holes. Specifically, the first rough blank structure 10 is a rough blank structure for a carbon fiber electric bicycle frame, but is not limited thereto. The number of machined holes on the first rough blank structure 10 is greater than or equal to 20 and less than or equal to 30. During the first processing of the first rough blank structure 10, the position of each hole 1 to be machined will deviate from the position in the design drawing due to the position deviation of the first rough blank structure 10 during the forming process. The machining program can only be written according to the design drawing. If the machining is carried out directly according to the program, it will cause the machining of each position to be offset. The machining offset will cause the first rough blank structure 10 product to be scrapped.

[0022] S2. A die-setting mold 2 is provided on each of the holes to be processed 1. The die-setting mold 2 is located in the middle of the hole to be processed 1. Specifically, an identical die-setting mold 2 is added to each hole to be processed 1. This die-setting mold 2 is used to assist in machine adjustment during the development period to more quickly find the actual processing position of each hole to be processed 1. Because the area of ​​the die-setting mold 2 is small and it is within the area of ​​the hole to be processed 1, even if there is a deviation, it will not cause the product to be scrapped.

[0023] S3. Based on the design drawings of the carbon fiber bicycle, a first machining program is formed for machining the machining positions of the die-cutting marks 2. The first machining program is used to process all the die-cutting marks 2. Specifically, based on the design drawings of the carbon fiber bicycle, the positions of each die-cutting mark 2 in the design drawings are obtained. Based on the positions of each die-cutting mark 2 in the design drawings, a first machining program for machining the die-cutting marks 2 is designed. In this embodiment of the invention, a CNC five-axis machining center is specifically used. When designing the carbon fiber bicycle, there are complete design drawings. Based on the design drawings, the positions of each die-cutting mark 2 in the design drawings can be obtained, thereby obtaining the first machining program.

[0024] S4. A first cutting tool is provided, the size of the working end of the first cutting tool is the same as the size of the die-setting mold 2. The first machining program controls the first cutting tool to perform hole-making on all the die-setting molds 2 and form a number of first pair of cutting holes. Specifically, the first pair of cutting holes are located inside the hole position 1 to be processed. Even if the processed first pair of cutting holes are offset relative to the die-setting mold 2, they are still inside the mounting hole. Therefore, even if the position of the first pair of cutting holes is offset, it will not cause the product to be scrapped. Since the die-setting mold 2 can be set to perform hole-making on all the die-setting molds 2 at one time through the first machining program and the offset amount can be uniformly captured, it is not necessary to process and debug and verify only one hole position 1 to be processed each time, which effectively saves processing time, improves processing efficiency and machine utilization. The working end of the first cutting tool may be a drill bit or a milling cutter, etc., which can be selected according to the processing requirements of different holes. The working end of the second cutting tool may be a drill bit or a milling cutter, etc., which can be selected according to the processing requirements of different holes.

[0025] S5. Record the offset between each first pair of tool holes and the corresponding tool die 2. Specifically, the offset between the actual hole position 1 to be processed and the hole position 1 to be processed in the design drawing is obtained by the offset between the first pair of tool holes and the tool die 2. This will not cause the scrapping of the first rough blank structure 10 product and can effectively save time. The design is very ingenious.

[0026] S6. Based on the design drawing of the carbon fiber bicycle, form a second machining program for the machining position of the hole to be machined 1. Revise the second machining program according to the offset to form a first revision program. Specifically, obtain the offset between the actual hole to be machined 1 and the hole to be machined 1 in the design drawing according to the offset between the first tool setting hole and the tool setting mold 2. Then, use the obtained offset to correct the second machining program to form the first revision program.

[0027] S7. A second cutting tool is provided, the size of the working end of the second cutting tool being the same as the size of the mounting hole. The second cutting tool is controlled according to the first revised program to machine several of the holes 1 to be machined on the first rough blank structure 10 to form the mounting hole. Specifically, the diameter of the working end of the second cutting tool is the same as the diameter of the mounting hole for machining the mounting hole. The size of the second cutting tool can vary with the size of the mounting hole. For example, if the first rough blank structure 10 needs to machine mounting holes with a diameter of 8 mm, 10 mm, etc., different sizes of second cutting tools are used to machine these mounting holes. All holes 1 to be machined are machined in one operation using the first revised program. Since the offset between the hole machined by the revised first revised program and the actual required mounting hole position is 0 or very small, the first rough blank structure 10 will not be directly scrapped. Even with a slight offset, the first rough blank structure 10 can still be used for other physical property tests and verifications.

[0028] This invention, by adding a die-setting mark 2 to the center of the hole to be processed 1, allows for the simultaneous drilling of all the die-setting marks 2 using a first machining program, and uniformly captures the offset. This eliminates the need to process only one hole 1 at a time and to debug and verify the machining program after each hole 1 is processed. Furthermore, by machining the die-setting mark 2 to obtain the offset value between the first die-setting hole and the die-setting mark 2, the second machining program is revised using this offset value to obtain the mounting hole at the required position, effectively improving debugging efficiency and machine utilization. Simultaneously, since the offset between the hole processed by the revised first program and the actual required mounting hole is 0 or very small, it will not cause direct scrapping of the first rough blank structure 10 product. Even with a slight offset, the first rough blank structure 10 product can still be used for other physical property tests and verifications, effectively saving costs.

[0029] In this embodiment of the invention, the die-setting mold 2 is a circular mold with a diameter of 6 mm, and the diameter of the working end of the first tool is also 6 mm. Specifically, the diameter of the mounting hole is greater than or equal to 8 mm, and the diameter of the die-setting mold 2 is smaller than the diameter of the mounting hole. For example, in this embodiment of the invention, the diameter of the die-setting mold 2 is 6 mm, the diameter of the working end of the first tool is the same as the diameter of the die-setting mold 2, and the dimensions of the die-setting mold 2 at all mounting positions are the same to facilitate uniform machining and uniform recording of offset.

[0030] In this embodiment of the invention, step S3, based on the design drawing of the carbon fiber bicycle, forms the first machining process for the machining position of the die-cutting mark 2, including:

[0031] S31. Based on the 3D model design drawing of the carbon fiber bicycle, obtain the design position of the die-cutting mark 2, and form a first machining formula for the machining position of the die-cutting mark 2 based on the design position of the die-cutting mark 2. Specifically, the design drawing of the carbon fiber bicycle is a 3D model design drawing, and the design position of the die-cutting mark 2 in the 3D model can be obtained based on this 3D model design drawing.

[0032] In this embodiment of the invention, step S6, revising the second machining program according to the offset and forming a first revision program, includes:

[0033] S61. Add all the aforementioned offsets to the second machining program and uniformly modify the second machining program to form a first revision program to revise the machining position of the hole 1 to be machined. Specifically, all the recorded offsets are added to the second machining program and uniformly modified. During the modification process, no machine time is required, and the machine can process other products, effectively improving the utilization rate of the machine and saving machine setup time.

[0034] In this embodiment of the invention, step S7, controlling the second tool to machine a plurality of the holes to be machined 1 on the first rough blank structure 10 to form the mounting holes according to the first revised program, further includes:

[0035] S71. The second tool is controlled according to the first revision program to machine a plurality of the holes to be machined 1 of the first rough blank structure 10 to form a first machined hole.

[0036] S72. Record the first offset value between the position of the first machined hole and the actual required position of the mounting hole. Specifically, if the accuracy of the first mounting hole machined by the first revision program meets the requirements of the actual required mounting hole, then there is no need to revise the first revision program. However, if the first offset value does not meet the requirements, the first revision program needs to be revised again. The first offset value in this step is the case where the requirements of the actual required mounting hole are not met.

[0037] S73. Revise the first revision program according to the first offset value and form a second revision program.

[0038] S74. Provide a second rough blank structure, which is formed by the same process as the first rough blank structure 10. Specifically, since the first rough blank structure 10 has already been processed with mounting holes, it is not appropriate to use the first rough blank structure 10 to verify the second revision program. Therefore, the second rough blank structure of the same model is used to verify the second revision program.

[0039] S75. The second tool is controlled according to the second revised program to machine a plurality of holes 1 to be machined on the second rough blank structure to form the mounting holes.

[0040] In this embodiment of the invention, step S75, controlling the second tool to machine a plurality of holes 1 to be machined on the second rough blank structure according to the second revised program to form the mounting holes, includes:

[0041] S751. The second tool is controlled to machine a plurality of holes 1 to be machined on the second rough blank structure according to the second revised program and form a second machined hole; specifically, the second machined hole is set in a one-to-one correspondence with the plurality of holes 1 to be machined.

[0042] S752. Record the second offset value between the second machined hole and the mounting hole at the actual required position. Specifically, if the second offset value does not meet the requirements, the second revision program needs to be revised further.

[0043] S753. Revise the second revision program according to the second offset value and form a third revision program.

[0044] S754. A third roughing stock structure is provided, which is formed using the same process as the second roughing stock structure. Specifically, the third roughing stock structure of the same type is used for verification of the third revision program.

[0045] S755. According to the third revision program, the second tool is controlled to machine a plurality of machined hole positions 1 of the third rough blank structure to form a third machined hole to verify the third revision program.

[0046] S756. Record the third offset value between the third machined hole and the mounting hole at the actual required position. If the third offset value is less than a preset value, there is no need to revise the third revision program. If the third offset value is greater than the preset value, repeat the aforementioned steps until the offset between the obtained machined hole and the mounting hole at the actual required position is less than the preset value. Specifically, when the third offset value is greater than the preset value, continue to provide a fourth rough blank structure and revise the third revision program using the third offset value. Continue to provide a fourth rough blank structure for verification until the offset between the obtained machined hole and the mounting hole at the actual required position is less than the preset value. The preset value can be determined according to the accuracy of the mounting hole to be machined.

[0047] In this embodiment of the invention, after step S7, which involves machining a plurality of the holes to be machined 1 in the first rough blank structure 10 according to the first revised program to form the first machined hole, the method further includes:

[0048] S8. Perform physical property tests on the first rough blank structure 10, including strength tests and hardness tests. Specifically, since the offset between the hole processed by the revised first revision program and the actual required mounting hole is 0 or very small, it will not cause the first rough blank structure 10 product to be directly scrapped. Even if there is a slight offset, the first rough blank structure 10 product can still be used for other physical property tests and verifications, including strength tests and hardness tests.

[0049] This invention also provides a method for using a machining tool, the method comprising:

[0050] S10. A first rough blank structure 10 of a carbon fiber bicycle and a first cutting tool are installed on the machine tool. The first rough blank structure 10 is provided with a plurality of holes 1 to be machined to form the mounting holes. Each hole 1 to be machined is provided with a tool setting mold 2. The tool setting mold 2 is located in the middle of the hole 1 to be machined. The size of the working end of the first cutting tool is the same as the size of the tool setting mold 2. Specifically, the first rough blank structure 10 to be machined is fixedly installed on the machine tool by a fixture for processing, and a corresponding first cutting tool is installed on the machine tool to process the position of the tool setting mold 2.

[0051] S20. Based on the design drawing of the carbon fiber bicycle, a first machining program is provided for machining the machining positions of the die-cutting marks 2. The first machining program is used to machine all the die-cutting marks 2. The first machining program is used to control the first tool to perform hole machining on all the die-cutting marks 2 to form the first pair of die holes. Specifically, based on the design drawing of the carbon fiber bicycle, the position of each die-cutting mark 2 in the design drawing is obtained. Based on the position of each die-cutting mark 2 in the design drawing, a first machining program for machining the die-cutting marks 2 is designed. In this embodiment of the invention, a CNC five-axis machining center is specifically used. When designing the carbon fiber bicycle, there is a complete design drawing. Based on the design drawing, the position of each die-cutting mark 2 in the design drawing can be obtained, thereby obtaining the first machining program. The design position of the die-cutting marks 2 can be obtained based on the three-dimensional model design drawing of the carbon fiber bicycle, and the first machining program for machining the die-cutting marks 2 is formed based on the design position of the die-cutting marks 2. The first pair of tool holes is located inside the hole position 1 to be processed. Even if the first pair of tool holes are offset relative to the tool setting die 2 after processing, they are still inside the mounting hole. Therefore, the offset of the first pair of tool holes will not cause the product to be scrapped. Since the tool setting die 2 can be set to open all the tool setting die 2 at one time through the first machining process and the offset amount can be uniformly captured, it is not necessary to process only one hole position 1 to be processed each time and to debug and verify the machining process after processing each hole position 1.

[0052] S30. Record the offset between each first pair of tool holes and the corresponding tool setting mold 2. Specifically, the offset between the actual hole position 1 to be processed and the hole position 1 to be processed in the design drawing is obtained by the offset between the first pair of tool holes and the tool setting mold 2. This will not cause the scrapping of the first rough blank structure 10 product and can effectively save time. The design is very ingenious.

[0053] S40. Remove the first rough blank structure 10 to process other carbon fiber bicycles. Specifically, after the offset of the first rough blank is recorded, the processing of the first rough blank structure 10 is completed, and the first rough blank structure 10 can be removed from the fixture so that other carbon fiber bicycles can be processed using the machine tool.

[0054] In this embodiment of the invention, step S10 is executed during a first time period, specifically, the first time period is approximately one hour. Steps S20 to S40 are executed during a second time period. Specifically, the first rough blank structure 10 is a rough blank structure for a carbon fiber electric bicycle frame, and the number of machining holes on the first rough blank structure 10 is greater than or equal to 20 and less than or equal to 30. The second time period is greater than or equal to 4 hours and less than or equal to 5 hours. Of course, the number of machining holes depends on the shape of the carbon fiber electric bicycle frame and can be greater than 30 or less than 20, but is generally greater than or equal to 20 and less than or equal to 30.

[0055] In this embodiment of the invention, the processing time of the machine is divided into day shift and night shift; both the first and second shifts are within the day shift. Specifically, the day shift is from 8:00 to 12:00 and from 13:00 to 17:00, and the night shift is from 18:00 to 8:00 the next day. The usage arrangement of the processing machine can be shown in Table 1 below.

[0056]

[0057] Table 1

[0058] As shown in Table 1, the machine preparation time is 1 hour, including installing the first rough blank structure 10, the first cutting tool, and the second cutting tool on the machine. Three hours are used to perform hole drilling on the die-cutting mold 2 and record the offset. The first machining program can be prepared in advance. The program is modified and the first revised program in the embodiment of the machining debugging method for carbon fiber bicycle mounting holes is formed during the 5-hour period from 13:00 to 18:00. Other carbon fiber bicycles can be processed from 13:00 to 8:00 the next day. The first rough blank structure 10 is processed for 4 hours on the second day to verify the first revised program. The first offset value was recorded, and the first revision program was fine-tuned in one hour to form the second revision program. Then, the second rough blank structure was processed in four hours to verify the second revision program. Other carbon fiber bicycles could be processed during the night shift on the second day. The machine time occupied was 1+3+4+1+4=13 hours. Even if the third rough blank structure was used for further verification, it would only take 18 hours. In fact, at most, only three identical rough blank structures need to be processed to obtain the accurate revised machining program for the hole position 11 to be processed. The machining and debugging process of the carbon fiber bicycle mounting holes was arranged during the day shift, and the utilization rate of the machine was very high.

[0059] The above-disclosed examples are merely preferred embodiments of the present invention and should not be construed as limiting the scope of the present invention. Therefore, any equivalent variations made in accordance with the claims of the present invention shall still fall within the scope of the present invention.

Record the second offset value between the second machined hole and the mounting hole at the actual required position; The second revision program is revised based on the second offset value to form the third revision program; A third preform structure is provided, which is formed by the same process as the second preform structure. The third revised program controls the second tool to machine a plurality of the holes to be machined in the third rough blank structure to form the third machined holes in order to verify the third revised program; Record the third offset value between the third machined hole and the actual required mounting hole. If the third offset value is less than the preset value, there is no need to revise the third revision program. If the third offset value is greater than the preset value, repeat the above steps until the offset between the obtained machined hole and the actual required mounting hole is less than the preset value.
