Description

Technical Field

[0001] The present invention relates to the field of mechanical equipment, in particular to a five-axis CNC end milling device and a use method thereof. Background Art

[0002] As attached Figure 14-15 As shown, since the muntin profile of the door and window needs to be mortised with the frame profile, it is necessary to perform milling on the two end faces of the muntin profile, and multiple grooves need to be milled during the milling process, and the grooves have different widths and depths. The existing end face processing of the muntin profile is mainly carried out by CNC end face milling machines. However, since most of the existing CNC end face milling machines use a single saw blade for milling, when facing multiple grooves of different widths, multiple reciprocating milling is required, and one-time milling cannot be achieved. At the same time, the end face of the muntin profile also needs to be cut off. During the cutting process, the cutting cutter used is not the same as the milling cutter used for milling grooves. This results in the need to perform the cutting process on the cutting equipment. If the profile is processed on the replacement equipment, it is very easy to affect the processing accuracy of the profile.

[0003] Furthermore, for existing CNC face milling machines, most of the loading operations of profiles are performed manually, and manual alignment of the profiles is required, which is undoubtedly a phenomenon that affects efficiency when performing large-scale processing operations. Moreover, for most CNC face milling machines, when processing the middle-mud profile, only the end face at one end can be processed, and the other end face needs to be manually replaced when processing. Although there are end milling devices with double-end workbenches in the existing market, they are relatively expensive and have high manufacturing costs. Therefore, it is now necessary to design a five-axis CNC face milling device and its use method to address the above-mentioned problems, so as to solve the problems of low processing efficiency of middle-mud profiles and slow efficiency of manual loading and unloading, and realize automated production. Summary of the invention

[0004] The purpose of the present invention is to provide a five-axis CNC end milling equipment and a method of using the same. When processing the end face of a profile, the cutting saw blade is set so that the end face of the profile can be processed in one go during the reciprocating cutting operation, thereby saving processing time and improving efficiency. It can also meet the cutting processing of grooves of different widths and depths on the end face of the profile. At the same time, a feeding mechanism can be provided to automatically complete the double-end cutting of the profile. In addition, for mass production processing and manufacturing, it can improve work efficiency, save labor, and save economic costs.

[0052] The present invention will be further described below in conjunction with specific embodiments. It should be understood that these embodiments are only used to illustrate the present invention and are not intended to limit the scope of the present invention. In addition, it should be understood that after reading the content taught by the present invention, those skilled in the art can make various changes or modifications to the present invention, and these equivalent forms fall within the scope limited by the application equally.

[0053] The present invention is a five-axis CNC end milling device, as shown in the attached Figure 1 , 3As shown in Figures 1 and 5, the main structure includes a frame 1, and a travel table 2 is slidably arranged on the upper end surface of the frame 1, and the sliding stroke of the travel table 2 here represents the Y-axis stroke of the machine tool. The left slide 3 and the right slide 4 are slidably arranged on the left and right end sides of the travel table 2, respectively, and the sliding stroke of the left slide 3 and the right slide 4 here is the Z-axis stroke of the machine tool, and the left slide 3 and the right slide 4 can move the Z-axis independently, and the left travel table 5 and the right travel table 6 are slidably arranged on the left slide 3 and the right slide 4 in the horizontal direction, and the sliding stroke of the left travel table 5 and the right travel table 6 here is the X-axis stroke of the machine tool, and the left travel table 5 and the right travel table 6 can move the X-axis independently, and the left travel table 5 and the right travel table 6 are provided with a milling mechanism 7 and a milling mechanism 8 in the vertical direction, and the left travel table 5 is provided with a rotating component 9 for driving the milling mechanism 7 to rotate.

[0054] The milling mechanism 7, the milling mechanism 8, and the rotating assembly 9 described above are described as follows:

[0055] As attached Figure 2 As shown in or 6, the milling mechanism 7 includes a first spindle motor 701, a first milling cutter saw blade 702, a cutting cutter saw blade 703, and a connecting shaft 704. It should be noted here that the first spindle motor 701 and the second spindle motor 801 described below are both dual-axis motors, and both ends of the motors have rotating shafts. The rotating assembly 9 includes a pushing cylinder 901, the cylinder body of the pushing cylinder 901 is hinged on the left travel table, the connecting shaft 704 is horizontally perpendicular to the left travel table 5, and one end of the connecting shaft 704 passes through the left travel table 5 and is connected to the piston rod of the pushing cylinder 901. Here, a through hole compatible with the connecting shaft 704 is provided on the left travel table 5. The first spindle motor 701 is fixedly connected to the other end of the connecting shaft 704 in the vertical direction, and the first milling cutter saw blade 702 and the cutting cutter saw blade 703 are respectively connected and arranged on the upper and lower rotating shafts of the first spindle motor 701. As shown in the attached Fig.15 As shown, the connecting shaft 704 can rotate under the push of the pushing cylinder 901, thereby enabling the first spindle motor 701 to rotate. It should be noted that when the milling cutter is in use, the milling cutter saw blade must be kept in a horizontal state, and when the cutter is in use, the cutter saw blade 703 must be kept in a vertical state. Therefore, when using the cutter, the first spindle motor 701 is rotated 90° to a horizontal state by pushing the cylinder 901. When using the milling cutter, the pushing cylinder 901 does not move, and the first spindle motor 701 is in a vertical state. Furthermore, since the first spindle motor 701 only needs to be rotated to 90°, a limiting member 501 is provided on the left travel table 5, and the limiting member 501 can limit the push of the pushing cylinder 901 and the rotation of the connecting shaft 704. As shown in the attached Figure 4As shown in Figure 6, the milling mechanism 8 includes a second spindle motor 801, a second milling cutter blade 802, and a third milling cutter blade 803. The second spindle motor 801 is fixedly connected to the right travel table 6 in the vertical direction. The second milling cutter blade 802 and the third milling cutter blade 803 are respectively connected to the output shafts at the upper and lower ends of the second spindle motor 801. It is hereby stated that the first milling cutter blade 702, and the second milling cutter blade 802 and the third milling cutter blade 803 mentioned above can be installed with milling cutter blades of different thicknesses.

[0056] When the milling mechanism 7 and the milling mechanism 8 are working, a height difference can be created between the left slide 3 and the right slide 4 mentioned above, so that the effect of cutting grooves at different positions on the end face of the profile can be achieved. At the same time, after the milling mechanism 7 and the milling mechanism 8 complete the first cutting stroke, when they return for cutting for the second time, they can adjust the height again, so that the cutting of grooves at different positions can be completed, and the depth of the groove cutting can also be adjusted, so that one reciprocating motion of the milling mechanism 7 and the milling mechanism 8 can complete the groove cutting at four different positions on the end face of the profile, which is sufficient to meet the processing requirements of the end faces of most profiles, and by installing saw blades of different thicknesses, the cutting of grooves of different widths can be achieved, so that one-time processing can be completed, and finally, the first spindle motor 701 on the milling mechanism 7 can be rotated by pushing the cylinder 901, so that the cutting saw blade 703 can perform cutting processing on the end face of the profile.

[0057] The driving relationship between the middle travel workbench 2 and the frame, the driving relationship between the travel workbench 2 and the left slide 3 and the right slide 4, and the driving rod relationship between the left slide 3 and the right slide 4 and the left travel platform 5 and the right travel platform 6 are described below:

[0058] As attached Figure 7 As shown, a gear drive structure 10 is arranged between the travel workbench 2 and the frame 1. The gear drive structure 10 specifically includes a gear 1001, a rack 1002, and a gear drive motor 1003. The rack 1002 is arranged on the frame 1 along the Y-axis direction, and the gear 1001 is arranged on the gear drive motor 1003. The gear drive motor 1003 is fixedly arranged on the travel workbench 2. At the same time, the drive of the gear drive motor 1003 causes the travel workbench 2 to slide along the frame 1. As shown in the attached figure Figure 8As shown, a screw drive structure 11 is arranged between the travel workbench 2 and the left slide 3 and the right slide 4, and a screw drive structure 11 is also arranged between the left slide 3 and the right slide 4 and the left travel platform 5 and the right travel platform 6. The screw drive structure 11 specifically includes a screw 1101, a moving block 1102, and a screw drive motor 1103. The screw drive motor 1103 is respectively arranged on the left and right ends of the travel workbench 2, the left travel platform 5, and the right travel platform 6. The moving block 1102 is respectively arranged on the left slide 3 and the right slide 4, and the screw 1101 is arranged in coordination. The above-mentioned gear drive motor 1003 and screw drive motor 1103 are both servo motors that can achieve precise control. Further, in order to facilitate the sliding between the above-mentioned multiple sliding structures, a slider guide structure is provided to facilitate the sliding of the above-mentioned multiple sliding structures.

[0059] Furthermore, when manufacturing and producing profiles in batches, for example, doors and windows uniformly installed in residential buildings and office buildings, the manual loading and unloading method is too cumbersome, and when both ends of the profile need to be processed, the manual replacement is also cumbersome, and this cumbersome operation method will make workers feel bored, tedious and tired after working for a long time. Figure 1 , 2 As shown in Figures 5 and 9, the device is provided with a feeding mechanism 12 at the side of the frame 1, and the feeding mechanism 12 includes a feeding platform 13, a rotating platform 14, a discharging platform 15, and a material fixing and processing platform 16. The material fixing and processing platform 16 is arranged on the frame 1, and one end of the rotating platform 14 and the discharging platform 15 are adjacent to the frame 1, and the feeding platform 13 is connected to the other end of the rotating platform 14. The feeding platform 13 mentioned above is used to convey the profile for processing, the rotating platform 14 is used to adjust the processing surface of the profile and the conveying direction of the profile, the discharging platform 15 is used to convey the processed profile, and the material fixing and processing platform 16 is used to clamp the profile to be processed. As shown in the attached figure Fig. 9 As shown, the conveyor belt 17 is arranged on the platform end surface of the feeding platform 13, the rotating platform 14, the discharging platform 15, and the fixed material processing platform 16. The function of the conveyor belt 17 is to transport the profiles. As for the specific structure of the conveyor belt 17, there are rotating shafts on both sides of the transmission belt, and the rotating shafts are connected to the output motor through a chain. Fig.10As shown, the rotating platform 14 is composed of a turntable 1401 and a base 1402. The conveyor belt 17 on the rotating platform 14 is arranged on the turntable 1401, and the turntable 1401 is rotatably connected to the upper end of the base 1402. The rotation of the turntable 1401 here is achieved by providing a gear set at the bottom end of the turntable 1401 and the upper end of the base 1402, and a servo drive motor 1404 is provided at the bottom end of the base 1402. The servo drive motor 1404 is used to drive the group to rotate, thereby enabling the turntable 1401 to rotate. After one end of the profile is processed, the profile will be pushed back onto the rotating platform 14. At this time, the rotating platform 14 needs to be rotated 180° before processing the other end of the profile. After the processing is completed, the profile continues to be pushed back onto the rotating platform 14. At this time, the rotating platform 14 rotates 90° to transport the profile to the discharge platform 15. As shown in the attached figure Fig.11 , 12 As shown, the material fixing and processing platform 16 is composed of a support table 1601, an end face positioning device 1602, a side face positioning device 1603, and a clamping device 1604. The end face positioning device 1602 is located at the processing end of the support table 1601 to perform end face positioning on the processing surface of the profile. The side face positioning device 1603 is located at the side end of the support table 1601 to squeeze the side of the profile to align it. The clamping device 1604 is located at the upper end of the support table 1601 to clamp and position the profile.

[0060] The specific structures of the middle end surface positioning device 1602, the side surface positioning device 1603, and the pressing device 1604 are described as follows:

[0061] As attached Fig.11 As shown, the end surface positioning device 1602 is composed of an end surface positioning plate 16021 and an end surface driving cylinder 16022. The end surface positioning plate 16021 is L-shaped. One end of the end surface positioning plate 16021 and the cylinder body of the end surface driving cylinder 16022 are hinged on the bottom surface of the support platform 1601. The piston rod of the end surface driving cylinder 16022 is connected to the end surface positioning plate 16021. Fig.14 As shown, under the push of the piston rod in the end driving cylinder 16022, the end positioning plate 16021 can rotate around its hinge point with the support platform 1601, so that one plate in the L-shaped structure stands upright at the processing end of the support platform 1601, thereby facilitating the end surface of the profile to work on it. Fig.12As shown, the side positioning device 1603 is composed of a side positioning plate 16031 and a side driving cylinder 16032. The side driving cylinder 16032 is arranged on the support platform 1601, and the side positioning plate 16031 is connected to the piston rod of the side driving cylinder 16032. Under the push of the piston rod in the side driving cylinder 16032, the side positioning plate 16031 moves along the side of the support platform 1601, so that the profiles can be aligned, and multiple profiles can be placed in parallel during one-time processing, so that there is no gap between the profiles after extrusion. At the same time, a side limit block is provided at the opposite end of the support platform 1601 to the side positioning device 1603. As shown in the attached figure Fig.11 As shown, the clamping device 1604 is composed of a clamping plate 16041, four support beams 16042, a support plate 16043, and a clamping drive cylinder 16044. The four support beams 16042 are vertically arranged in a square shape on the upper end surface of the support platform 1601. The clamping plate 16041 and the support plate 16043 are arranged through the four support beams 16042. The clamping plate 16041 is located at the lower end position of the support plate 16043 and can move relative to the supporting connecting rod. The clamping drive cylinder 16044 is fixedly arranged at the upper end position of the support plate 16043, and the piston rod of the clamping drive cylinder 16044 passes through the support plate 16043 and is connected to the clamping plate 16041, driving the clamping plate 16041 to move along the support beams 16042. Driven by the piston rod in the clamping drive cylinder 16044, the clamping plate 16041 can move downward to clamp the profile during processing.

[0062] A method for using a five-axis CNC end milling device comprises the following steps:

[0063] S1, the end surface driving cylinder 16022 on the material fixing processing platform 16 pushes the end surface positioning plate 16021, so that the end surface positioning plate 16021 stands upright on the processing end of the material fixing processing platform 16;

[0064] S2, the profiles to be cut are neatly arranged and placed on the conveyor belt of the feeding platform 13, and the conveyor belt 17 is started to rotate forward, so that the profiles move forward;

[0065] S3, the profile moves to the rotating platform 14, and the conveyor belt 17 on the rotating platform 14 also rotates forward, so that the profile moves to the material setting processing platform 16, and the conveyor belt 17 on the material setting processing platform 16 rotates forward, so that the profile is aligned by the end surface positioning plate 16021, and at the same time, the side driving cylinder 16032 on the material setting processing platform 16 moves to push the side positioning plate 16031 to position the side of the profile;

[0066] It should be noted here that when the profile moves onto the rotating platform 14 , the conveyor belt 17 on the feeding platform 13 stops rotating.

[0067] S4, after the end and side positioning is completed, the conveyor belt 17 on the rotating platform 14 and the conveyor belt 17 on the fixed material processing platform 16 stop rotating, the end surface driving cylinder 16022 retracts the end surface positioning plate 16021, so that the end surface positioning plate 16021 is located at the lower end position of the support platform 1601 as a whole, and the side surface driving cylinder 16032 retracts the side surface positioning plate 16031 back to the initial position;

[0068] As for how to determine that all the profiles on the material fixing and processing platform 16 have completed end face alignment, an explanation is given. A detection probe is provided on the processing end of the support table 1601, so that it can be known that all the profiles can be aligned, thereby stopping the rotation of the conveyor belt 17. It is also possible to set a rotation time for the conveyor belt 17 on the material fixing workbench, and this rotation time can ensure that all the profiles are aligned. This problem is not the main problem to be solved by this device.

[0069] S5, the clamping plate 16041 is driven by the clamping driving cylinder 16044 to descend to clamp the profile, and the cutting program is started at this time, and the milling mechanism 7 and the milling mechanism 8 cut the end surface of the profile;

[0070] S6, after the cutting process is completed, the milling mechanism 7 and the milling mechanism 8 return to the origin, and the pressing driving cylinder 16044 recycles the pressing plate 16041;

[0071] S7, the material processing platform 16 and the conveyor belt 17 on the rotating platform 14 are reversed, and at the same time, the end surface driving cylinder 16022 pushes the end surface positioning plate 16021 again to prepare for end surface positioning;

[0072] S8, when the profile is returned to the rotating platform 14 as a whole, the material processing platform 16 and the conveyor belt 17 on the rotating platform 14 stop rotating, and the turntable 1401 rotates forward to 180° as shown in the figure. Fig.13 As shown in B, the other end face of the profile begins to be processed, the conveyor belt 17 on the rotating platform 14 reverses, and the transmission belt on the fixed material processing platform 16 rotates forward, so that the profile moves to the fixed material processing platform 16 and is positioned by the end face positioning plate 16021 and the side positioning plate 16031. Here, how to know that the profile has returned to the rotating platform 14 as a whole is explained. A detection probe is also set at the opposite end of the processing end of the support platform 1601. When the profile exits the support platform 1601 as a whole, the fixed material processing platform 16 and the conveyor belt 17 on the rotating platform 14 are controlled to stop rotating, which can also be achieved by setting the rotation time as described above.

[0073] S9, repeat steps S4-S6;

[0074] S10, the conveyor belt 17 on the material processing platform 16 starts to reverse, the transmission belt on the rotating platform 14 starts to rotate forward, and at the same time, the end surface driving cylinder 16022 pushes the end surface positioning plate 16021 again to prepare for end surface positioning;

[0075] S11, after the profile is returned to the rotating platform 14 as a whole, the material processing platform 16 and the conveyor belt 17 on the rotating platform 14 stop rotating, and the turntable 1401 is reversed to 90 degrees as shown in the attached figure Fig.13 As shown in C;

[0077] S13, after the profile leaves the rotating platform 14 as a whole, the rotating platform 1401 continues to rotate 90 degrees as shown in the figure Fig.13 As shown in A, return to the initial position;

[0078] S14, the conveyor belt 17 on the feeding platform 13 and the rotating platform 14 starts to rotate forward, so that the next section of the profile can be processed; here, the conveyor belt 17 on the feeding platform 13 starts to rotate, and can be reversed to the initial position for sensing by the turntable 1401, which can be achieved through the CNC electronic programming system, and is not the main problem solved by this device.

[0079] S15, repeat steps S3-S13.

[0080] Since the profiles have different lengths, in order to facilitate the rotation of the profiles, the position gap between the feeding platform 13 and the rotating platform 14, and the position gap between the rotating platform 14 and the material fixing and processing platform 16 are adjustable, and can be adjusted according to the actual length of the profiles. Further, in order to facilitate adjustment, universal wheels are provided at the bottom of the feeding platform 13, the rotating platform 14, the material fixing and processing platform 16, and the discharging platform 15.
