Description

Technical Field

[0001] The present invention belongs to the technical field of machining of mechanical parts, and specifically relates to a device for machining flange threaded holes. Background Art

[0002] A flange, also known as a flange or a collar, is a mechanical part that connects pipes to each other and is connected to the pipe end. During the machining and manufacturing process of a flange, a machining device is usually used to turn threads on the inner wall of the flange, so that threaded holes are formed in the hollow part of the flange, thereby completing the machining and manufacturing of the flange.

[0003] A patent with the publication number CN215788076U discloses a device for machining threaded holes of a bridge housing flange. The device limits the depth of the support rod extending into the blind hole of the driven shaft through a depth limiting member to ensure the installation and positioning accuracy of the support rod. A reducer provides power for the driving shaft, thereby driving a plurality of drill rods to rotate to machine the flange holes; the output end of the reducer is connected to the driving shaft through a coupling, thereby realizing the power transmission of the driving shaft. The driving bridge housing can be positioned through an elastic positioning mechanism first, and the distance between the positioned driving bridge housing and the numerical control slide table can be adjusted. Then, it is convenient to connect the flange and the numerical control slide table through the mounting plate.

[0004] The above solution still has some problems in actual application. Usually, a triangular chuck is used to clamp and fix the flange, and then the tool holder of the turning tool is controlled to drive the tool to move into the inner cavity of the flange. At the same time, the tool is controlled to fit the inner wall of the flange, and the triangular chuck is driven to drive the flange to rotate, thereby machining threads on the inner wall of the flange. However, this machining method cannot use the triangular chuck to clamp and fix flanges of different sizes, and the waste chips generated by turning the inner wall of the flange will accumulate in the inner cavity of the flange, which will cause hard particles to form between the tool and the workpiece. Moreover, the waste chips are repeatedly extruded in the cutting area, which will accelerate the wear of the flank face of the tool, even cause chipping, shorten the tool life, and also cause problems with the accuracy of the threads.

[0021] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific implementation manners.

[0022] Embodiment 1: As Figures 1 to 9 shown, a flange thread hole machining device described in an embodiment of the present invention includes a workbench 1, a mounting bracket 2 is fixedly connected to the upper end surface of the workbench 1, a servo push rod 3 is installed on the upper end surface of the mounting bracket 2, and a turning component 9 is installed at the piston rod end of the servo push rod 3; And the turning component 9 includes a support frame 91 installed at the piston rod end of the servo push rod 3. A T-shaped sliding groove 92 is opened inside the lower end of the support frame 91. Two T-shaped sliding blocks 95 are slidably connected inside the T-shaped sliding groove 92. Insertion slots 96 are opened at the lower ends of the two T-shaped sliding blocks 95. A turning tool holder 10 is installed inside the insertion slot 96 at the lower end of one of the T-shaped sliding blocks 95, which is used to drive the turning tool holder 10 to drive the tool to move, and can adjust the turning position according to flange plates 5 with different inner diameters; A clamping and positioning component 4 is arranged inside the upper end of the workbench 1; Moreover, the clamping and positioning component 4 includes an annular frame 41 rotatably connected to the upper end inside the workbench 1. A plurality of grooves 42 are formed in the inner wall of the annular frame 41, and an L-shaped telescopic block 43 is slidably connected to the inner cavity of the plurality of grooves 42. The upper end of the L-shaped telescopic block 43 is rotatably connected to a pressing block 44. The L-shaped telescopic block 43 is used to support the flange 5 and can drive the pressing block 44 to flip to clamp and fix the flange 5.

[0023] Specifically, in the prior art, a triangular chuck is usually used to clamp and fix the flange, and then the turning tool holder is controlled to drive the tool to move into the inner cavity of the flange. At the same time, the tool is controlled to fit the inner wall of the flange, and the triangular chuck is driven to drive the flange to rotate, so as to machine the thread on the inner wall of the flange. However, this machining method cannot use the triangular chuck to clamp and fix flanges of different sizes, and the waste chips generated by the tool turning the inner wall of the flange will accumulate in the inner cavity of the flange, resulting in the formation of hard particles between the tool and the workpiece. Moreover, the waste chips are repeatedly extruded in the cutting area, which will accelerate the wear of the flank face of the tool, even cause chipping, shorten the tool life, and also cause problems with the accuracy of the thread. When turning the thread on the inner diameter of the flange 5 in the present invention, the flange 5 is placed in the inner cavity of the annular frame 41, and the flange 5 is pressed on the L-shaped telescopic block 43. At the same time, the weight of the flange 5 is used to drive the L-shaped telescopic block 43 to move downward. At the same time, the L-shaped telescopic block 43 drives the pressing block 44 to move downward. During the process of driving the pressing block 44 to move downward, the pressing block 44 will be driven to flip, and the pressing block 44 will clamp the flange 5 on the L-shaped telescopic block 43. Then, by driving the annular frame 41 to rotate, the annular frame 41 drives the L-shaped telescopic block 43 and the pressing block 44 to rotate synchronously, and then drives the flange 5 to rotate. At the same time, by starting the servo push rod 3 to drive the support frame 91 to move downward, the support frame 91 drives the T-shaped slider 95 to move downward, and then drives the turning tool holder 10 and the tool to move synchronously. Moreover, the T-shaped slider 95 is driven to slide in the inner cavity of the T-shaped chute 92 to adjust the turning position, so as to facilitate the turning tool holder 10 to drive the tool to turn the thread on the inner wall of the flange 5 with different inner diameters, thus achieving the effect of being able to turn according to the inner diameter of flanges 5 of different sizes. Moreover, when turning the inner diameter thread of the relatively light flange 5, by using the support frame 91 to drive the T-shaped slider 95 to move downward, and the support frame 91 presses the flange 5 to move downward, so that the flange 5 drives the L-shaped telescopic block 43 to move downward, and then drives the pressing block 44 to move downward and flip, so as to clamp and fix the flange 5. The waste chips generated by turning the inner wall of the flange 5 will fall below the workbench 1 through the annular frame 41. At the same time, a recycling box is arranged below the workbench 1 to collect the waste chips generated by turning the inner wall of the flange 5, thus solving the above problems.

[0024] Such as Figures 5 to 8As shown in the figure, a bidirectional threaded rod 93 is rotatably connected to the inner cavity of the T-shaped chute 92. The outer part of the bidirectional threaded rod 93 is threadedly connected to two T-shaped sliders 95. The lower end of one of the T-shaped sliders 95 is located inside the slot 96 and is equipped with a grinding and polishing assembly for grinding and polishing the threads turned out on the inner wall of the flange 5.

[0025] As Figures 5 to 8 shown in the figure, a turning tool holder 10 is installed inside one side of the turning tool seat 10, and a turning tool 11 is installed inside one side of the turning tool holder 10. The turning tool holder 10 is internally threadedly connected to an adjusting bolt 12, and the adjusting bolt 12 is used to abut and fix the turning tool 11.

[0026] Specifically, when machining the threads on the inner wall of the flange 5, by driving the bidirectional threaded rod 93 to rotate, and making the bidirectional threaded rod 93 threadedly drive the two T-shaped sliders 95 to move away from each other. At the same time, the two T-shaped sliders 95 drive the turning tool holder 10 and the grinding and polishing assembly to move synchronously, so as to adjust the tool position according to the flanges 5 with different inner diameters. Moreover, when turning the threads to be machined, by turning the turning tool 11 to rotate and adjust the inclination angle, and then turning the adjusting bolt 12 to abut and fix the turning tool 11, thus realizing that when machining different threads, the inclination angle of the turning tool 11 can be easily adjusted, solving the problem that when the existing flange thread processing device turns and processes the threads on the inner wall of the flange, because the processing device can only process one kind of thread, and if processing the required threads, only the matching processing device can be used to turn and process the threads on the inner wall of the flange, resulting in inconvenient use and affecting the processing efficiency of the threads on the inner wall of the flange.

[0027] As Figures 5 to 8 shown in the figure, the grinding and polishing assembly includes a T-shaped insertion rod 13 installed inside the lower end of the T-shaped slider 95. A plurality of T-shaped telescopic grooves 17 are opened on one side of the T-shaped insertion rod 13, and a T-shaped grinding column 16 is installed in the inner cavity of each of the plurality of T-shaped telescopic grooves 17. A flexible grinding layer is arranged on the outer part of the T-shaped grinding column 16, which can deform according to the inner cavity of the thread groove, so that it can be evenly attached to the inner cavity of the thread groove.

[0028] As Figures 5 to 8 shown in the figure, a second spring 14 is installed in the inner cavity of the T-shaped telescopic groove 17. A resisting plate 15 is inserted into the upper end inside the T-shaped insertion rod 13, and the resisting plate 15 is used to abut against the second spring 14. A servo motor 94 is installed on one side of the support frame 91, and the output shaft end of the servo motor 94 is fixedly connected to the bidirectional threaded rod 93.

[0029] Specifically, when machining the inner wall of the flange 5 with threads, the servo motor 94 is started to drive the bidirectional threaded rod 93 to rotate, and the bidirectional threaded rod 93 thread-drives the two T-shaped sliders 95 to move away from each other. At the same time, the two T-shaped sliders 95 drive the turning tool holder 10 and the T-shaped insertion rod 13 to move synchronously. Furthermore, the turning tool holder 10 drives the turning tool 11 to fit with the inner wall of the flange 5, while the T-shaped insertion rod 13 drives the T-shaped grinding column 16 to fit with the inner wall of the flange 5. Then, the flange 5 is driven to rotate by driving the annular frame 41. At the same time, the inner wall of the flange 5 is machined with threads by using the turning tool 11. After the threads machined on the inner wall of the flange 5 rotate to the position of the T-shaped grinding column 16, the second spring 14 in the inner cavity of the T-shaped expansion groove 17 pops up the T-shaped grinding column 16, and the T-shaped grinding column 16 is inserted into the threads on the inner wall of the flange 5. At the same time, with the rotation of the flange 5, the inner wall of the threads is polished by using the T-shaped grinding column 16. A flexible grinding layer is arranged outside the T-shaped grinding column 16, so that it can deform according to the inner cavity of the threads and uniformly fit with the inner cavity of the threads, so as to ensure the grinding accuracy and effect of the inner wall of the threads. At the same time, it can also grind the protruding parts of the threads, solving the problem that after the existing flange thread hole processing device finishes machining the threads on the inner wall of the flange, due to the inconvenience of grinding the machined threads, the waste chips generated by turning on the inner wall of the threads will be squeezed with the turning tool to form particles. If the inner wall of the threads is not ground to ensure its smoothness, the threads will be stuck during later use, affecting the use of the flange.

[0030] As Figures 1 to 4 and Figure 9 As shown, a gear ring 45 is fixedly connected to the outside of the annular frame 41. A rotation groove 8 is formed inside the upper end surface of the workbench 1. A gear disk 7 is rotatably connected to the inner cavity of the rotation groove 8, and the gear disk 7 is meshed with the gear ring 45.

[0031] As Figures 1 to 4 and Figure 9 As shown, a driving motor 6 is fixedly connected to the upper wall of the lower end of the workbench 1. The output shaft end of the driving motor 6 penetrates through the workbench 1 and is fixedly connected to the gear disk 7 in the inner cavity of the rotation groove 8.

[0032] Specifically, when clamping and fixing the flange 5 to machine threads, the driving motor 6 is started to drive the gear disk 7 to rotate, and the gear disk 7 meshes and drives the gear ring 45 to rotate, and the gear ring 45 drives the annular frame 41 to rotate, then drives the flange 5 to rotate. At the same time, in cooperation with the turning tool 11 and the T-shaped grinding column 16, the inner wall of the flange 5 is machined with threads, and at the same time, the machined threads are ground, improving the quality of the machined flange.

[0033] Embodiment 2: As Figures 1 to 4 and Figure 9As shown, limiting grooves 46 are formed in both inner walls of the inner cavity of the groove 42. The L-shaped telescopic block 43 is slidably connected in the inner cavity of the limiting groove 46. A first spring 49 is fixedly connected to the bottom of the inner cavity of the limiting groove 46, and one end of the first spring 49 is fixedly connected to the L-shaped telescopic block 43.

[0034] As Figures 1 to 4 and Figure 9 shown, gears 48 are fixedly connected to both sides of the pressing block 44. A rack 47 is installed on the inner wall of the limiting groove 46, and the gear 48 is meshed with the rack 47.

[0035] As Figures 1 to 4 and Figure 9 shown, an anti-slip rubber pad is arranged on one side of the pressing block 44, and the anti-slip rubber pad is used to increase the clamping stability of the pressing block 44 on the flange 5.

[0036] Specifically, when machining the inner wall of the flange 5 with threads, the flange 5 is placed on the L-shaped telescopic block 43. Then, the weight of the flange 5 is used to press the L-shaped telescopic block 43 to move downward. At the same time, the L-shaped telescopic block 43 drives the pressing block 44 to move downward, and the pressing block 44 drives the gear 48 to slide downward in the inner cavity of the limiting groove 46. During the downward movement of the gear 48, it will be meshed with the rack 47. At the same time, during the downward movement of the pressing block 44, the gear 48 will rotate along the rack 47, and then drive the pressing block 44 to flip. Since an anti-slip rubber pad is arranged on one side of the pressing block 44, the pressing block 44 can be used in cooperation with the anti-slip rubber pad to abut and press-fix the flange 5. At the same time, the pressing block 44 can also abut the flange 5 to always ensure that it is at the center position of the annular frame 41, so as to facilitate the turning tool 11 to more accurately machine the inner wall of the flange with threads, thus solving the problem that when the existing flange thread hole machining device machines and turns the threads on the inner wall of the flange, since the flange is usually clamped by a three-jaw chuck, but this clamping operation is cumbersome, the installation and disassembly efficiency of the flange is low, and the processing efficiency of the flange is affected.

[0037] Working principle: When turning the thread on the inner diameter of the flange 5, the flange 5 is placed in the inner cavity of the annular frame 41, and the flange 5 is pressed against the L-shaped telescopic block 43. At the same time, the weight of the flange 5 drives the L-shaped telescopic block 43 to move downward. Meanwhile, the L-shaped telescopic block 43 drives the pressing block 44 to move downward. During the process of driving the pressing block 44 to move downward, the pressing block 44 will be driven to flip, and the pressing block 44 will clamp the flange 5 on the L-shaped telescopic block 43. Then, by driving the annular frame 41 to rotate, the annular frame 41 drives the L-shaped telescopic block 43 and the pressing block 44 to rotate synchronously, thereby driving the flange 5 to rotate. At the same time, by starting the servo push rod 3, the support frame 91 is driven to move downward, and the support frame 91 drives the T-shaped slider 95 to move downward, thereby driving the turning tool holder 10 and the tool to move synchronously. Moreover, the T-shaped slider 95 is driven to slide in the inner cavity of the T-shaped chute 92 to adjust the turning position, so as to facilitate the turning tool holder 10 to drive the tool to turn the thread on the inner wall of the flange 5 with different inner diameters, thus achieving the effect of being able to perform turning work according to the inner diameter of the flange 5 with different sizes. And when turning the inner diameter thread of the flange 5 with a relatively light weight, by using the support frame 91 to drive the T-shaped slider 95 to move downward, and the support frame 91 presses the flange 5 to move downward, thereby driving the flange 5 to drive the L-shaped telescopic block 43 to move downward, and then driving the pressing block 44 to move downward and flip, so as to clamp and fix the flange 5. The waste chips generated by turning the inner wall of the flange 5 will fall into the lower part of the workbench 1 through the annular frame 41. At the same time, a recycling box is arranged under the workbench 1 to collect the waste chips generated by turning the inner wall of the flange 5; When processing the thread on the inner wall of the flange 5, the flange 5 is placed on the L-shaped telescopic block 43. Then, the weight of the flange 5 is used to press the L-shaped telescopic block 43 to move downward. Meanwhile, the L-shaped telescopic block 43 drives the pressing block 44 to move downward, and the pressing block 44 drives the gear 48 to slide downward in the inner cavity of the limiting groove 46. During the downward movement of the gear 48, it will mesh with the rack 47. At the same time, during the downward movement of the pressing block 44, the gear 48 will rotate along the rack 47, thereby driving the pressing block 44 to flip. One side of the pressing block 44 is provided with an anti-slip rubber pad, so that the pressing block 44 can cooperate with the anti-slip rubber pad to press and fix the flange 5. At the same time, the pressing block 44 can also abut against the flange 5 to always ensure that it is at the center position of the annular frame 41, so as to facilitate the turning tool 11 to more accurately turn and process the thread on its inner wall; When machining the inner wall of the flange 5 with threads, the servo motor 94 is started to drive the bidirectional threaded rod 93 to rotate, and the bidirectional threaded rod 93 thread-drives the two T-shaped sliders 95 to move away from each other. At the same time, the two T-shaped sliders 95 drive the turning tool holder 10 and the T-shaped insertion rod 13 to move synchronously. Then, the turning tool holder 10 drives the turning tool 11 to fit against the inner wall of the flange 5, and the T-shaped insertion rod 13 drives the T-shaped grinding column 16 to fit against the inner wall of the flange 5. Then, the flange 5 is driven to rotate by driving the annular frame 41. At the same time, the inner wall of the flange 5 is machined with threads by using the turning tool 11. After the threads machined on the inner wall of the flange 5 rotate to the position of the T-shaped grinding column 16, the second spring 14 in the inner cavity of the T-shaped expansion slot 17 bounces up the T-shaped grinding column 16, and the T-shaped grinding column 16 is inserted into the threads on the inner wall of the flange 5. At the same time, with the rotation of the flange 5, the inner wall of the threads is polished by using the T-shaped grinding column 16. A flexible grinding layer is arranged outside the T-shaped grinding column 16, so that it can deform according to the inner cavity of the threads and be evenly attached to the inner cavity of the threads, so as to ensure the grinding accuracy and effect of the inner wall of the threads. At the same time, it can also grind the raised parts of the threads, thus completing the processing work of the flange threaded hole.
