Description

Technical Field

[0001] The present invention belongs to the technical field of lathe processing, and specifically relates to a milling device for the inner groove of an S elbow. Background Art

[0002] In some complex environments, an S-bend joint is required. One end of the S bend is connected to a pipeline, and the other end of the S bend is connected to another pipeline, so that two pipelines at different heights can be connected together with only one joint. The existing S-bend joints are mass-produced using molds during production. The produced molds are solid structures, and then the molds are fixed to a numerical control machine tool and turned by a tool to machine holes with suitable diameters inside the S-bend joints.

[0003] Since the pipe fittings of the S elbow need to ensure a high cutting accuracy of the tool during turning work, but when processing a large number of S pipe fittings, each pipe fitting may gradually deviate during the fixing work. Therefore, after each installation of the pipe fitting, high-precision adjustment work needs to be carried out, consuming a large amount of time and resulting in a problem of reduced processing efficiency. Therefore, improvement is needed. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the technical solution adopted by the present invention to solve its technical problems is: a milling device for the inner groove of an S elbow, including a milling support member, a calibration device is arranged in the middle of the milling support member, and a transfer device is arranged at the bottom of the milling support member; The calibration device includes an upper cover shell, a compression gasket is fixedly connected to the inner wall of the upper cover shell, a lower cover shell is fixedly connected to the bottom of the compression gasket, and the upper cover shell and the lower cover shell are connected and combined into a circular disc body through the compression gasket. An adaptation cutting groove is opened at the top of the inner cavity of the upper cover shell. The adaptation cutting groove is S-shaped as a whole to adapt to the processed pipe body, but the two ends are significantly expanded, and only the bent area in the middle is adapted to the S-shaped pipe body, and the adaptation cutting groove extends to the outside of the lower cover shell. The S pipe can pass through the calibration device through the adaptation cutting groove in a flat state. Pressure-sensitive ends are symmetrically fixedly connected to the center of the top of the inner wall of the upper cover shell, a plug-in wire is fixedly connected to the top of the pressure-sensitive end, and an alarm is fixedly connected to the end of the plug-in wire away from the pressure-sensitive end; The milling support member includes a docking support plate. A guiding rotating groove is opened on one side of the inner cavity of the docking support plate close to the calibration device. An arc-shaped guiding rail is fixedly connected to one side of the upper surface of the docking support plate close to the pressure-sensitive end. A protective rotating shell is rotatably connected to the top of the inner wall of the arc-shaped guiding rail. The two docking support plates are combined with the disc body of the calibration device through the guiding rotating groove, and the two docking support plates can be perfectly docked to form a long plate, and the two arc-shaped guiding rails are also docked to form an arc-shaped rotating rail.

[0005] Further, the outer surface of the upper cover shell is rotatably connected to the inner cavity of the docking support plate through a guiding rotating groove, the outer surface of the lower cover shell is mutually pressed against the inner cavity of the docking support plate through a guiding rotating groove, one end of the inserted wire away from the pressure-sensitive end extends into the interior of the protective rotating shell through a through-hole, and the outer surface of the alarm is rotatably connected to the inner wall of the arc-shaped guiding rail.

[0006] Further, a displacement sliding groove is provided on one side of the inner cavity of the docking support plate away from the arc-shaped guiding rail, and a vertical pushing plate is arranged on the inner wall of the displacement sliding groove. The top end of the vertical pushing plate is fixedly connected with a control motor, the top end of the output shaft of the control motor is fixedly connected with a cutting tool head. The bottom end of the vertical pushing plate is fixedly connected with a control sliding plate. The control sliding plate can drive the vertical pushing plate to slide along the displacement sliding groove, so as to adjust the cutting point of the cutting tool head. The upper surface of the control sliding plate is slidably connected to the lower surface of the docking support plate through rollers. The bottom end of the vertical pushing plate extends into the interior of the control sliding plate. The outer surface of the vertical pushing plate is slidably connected to the inner cavity of the docking support plate through the displacement sliding groove, and both the upper and lower ends of the vertical pushing plate extend outside the displacement sliding groove. The number of the docking support plates is two, the number of the protective rotating shells is two, the lower surface of the docking support plate is fixedly connected to the ground, the number of the pressure-sensitive ends is two, and the bottom end of the pressure-sensitive end is mutually pressed against the inner wall of the lower cover shell.

[0007] Further, the transfer device includes a fixed chassis. A control turntable is rotatably connected to the center of the upper surface of the fixed chassis. Roller shaft pushing boxes are symmetrically arranged at the center of the upper surface of the control turntable. A side clamping plate is slidably connected to the top of the inner wall of the control turntable. A processed S pipe is arranged on the inner wall of the side clamping plate. The two side clamping plates can clamp the side parts of the end of the processed S pipe, as Figure 6 shown. Since both ends of the adapted cutting groove are expanded, when the side clamping plates slide vertically upward under the control of the roller shaft pushing boxes, the two side clamping plates and the processed S pipe can penetrate through the adapted cutting groove. Feeding bins are symmetrically arranged on both sides of the upper surface of the fixed chassis. The top end of the side clamping plate penetrates through the outside of the upper cover shell through the adapted cutting groove. The number of the roller shaft pushing boxes is two, and the lower surface of the roller shaft pushing box is fixedly connected to the upper surface of the control turntable. Both ends of the outer surface of the processed S pipe are mutually pressed against the inner wall of the side clamping plate.

[0008] Furthermore, the feed bin includes a side fixed plate, the upper surface of the side fixed plate is fixedly connected to an extended side box through a support rod, the side of the inner cavity of the extended side box away from the docking support plate is slidably connected to a push slide rod through a slide groove, and the end of the push slide rod away from the docking support plate is fixedly connected to an external slide cylinder, and the end of the push slide rod close to the docking support plate is fixedly connected to a vertical guide plate, the end of the push slide rod can be extended, so as to push the clamped S tube inwardly, and the upper and lower sides of the outer surface of the vertical guide plate are symmetrically provided with arc-shaped clamping plates through claws, the arc-shaped clamping plates on both sides can first clamp the end of the placed S tube, and then push them to the side clamping plates to realize the work of transferring the tube body. Since the arc-shaped clamping plates are vertically symmetrically arranged and staggered with the side clamping plates symmetrically arranged on the left and right, there will be no work obstruction problem. The outer surface of the external slide is slidably connected to the outer surface of the extended side box, the outer surface of the arc-shaped clamping plate is slidably connected to the outer surface of the vertical guide plate, and the inner cavity of the extended side box is symmetrically provided with feed cutting notches on one side close to the docking support plate, and the lower surface of the side fixed plate is fixedly connected to the upper surface of the fixed chassis.

[0009] The beneficial effects of the present invention are as follows: 1. The device can completely penetrate the inner wall of the S-tube to realize the milling of the inner groove of the S-tube. Since the S-tube may gradually deviate when being fixed, high-precision adjustment work is required after each installation of the pipe fitting, which consumes a lot of time and leads to reduced processing efficiency. Therefore, the device is equipped with a calibration device at the axis. When the S-tube can pass through the matching groove smoothly, it means that the S-tube is automatically calibrated to the axis position, and the tube body will not deviate thereafter, and the cutting head can realize the processing work. By converting the calibration work of the tube body into a clear indication that can be passed through the matching groove, it is ensured that the S-tube passing through the matching groove can be stably in the axis position for milling work, thereby saving the time for accurate calibration of the S-tube, and at the same time ensuring that the final position of the tube body can be milled without deviation.

[0010] 2. The adapting grooves of the cover shells on both sides can be customized according to the model of the S-tube. Since the calibration device and the docking brackets on both sides are combined together in a splicing manner, the calibration device can be replaced at any time to adapt to different types of S-tubes, ensuring that the use conditions of the device are more flexible and can perform precise milling work on S-tubes of different sizes. The S-tube located at the axial position has the characteristics of symmetry, so the cutting heads on both sides can perform milling work synchronously, thereby effectively improving the milling work efficiency.

[0011] 3. When the cutting tool head mills the inner wall of the S pipe, the chips generated by milling will fall off and then land on the upper surfaces of the docking support plate and the calibration device. To avoid the problem that chips accumulate inside the arc-shaped guide rail and affect the rotation of the cover shell, a protective rotating shell is provided to prevent chips from interfering with the movement track of the alarm device. For the chips that fall on the upper surface of the cover shell, the accumulated chips can also be collected by removing the calibration device, thereby realizing the recycling of chips and avoiding the problem that chips fall disorderly inside the device, making the cleaning work difficult.

[0012] 4. The device clamps the S pipe through the side clamping plates and pushes it upward to adjust the horizontal height of the pipe body. The arc-shaped clamping plates are used for fine-tuning the transfer of the pipe body to adjust the position of the pipe body on the horizontal plane, ensuring that the pipe body can smoothly pass through the matching cutting groove. When the pipe body cannot pass through the matching cutting groove, the lower cover shell will be pressed to trigger the alarm device. At this time, the side clamping plates will promptly reduce the force to prevent the side clamping plates from continuously pushing the pipe body that cannot pass through the matching cutting groove, avoiding the problem that the cover shell is damaged and deformed due to excessive force.

[0017] The outer surface of the upper cover 31 is rotatably connected to the inner cavity of the docking support plate 11 through the guiding rotating groove 13, the outer surface of the lower cover 33 is squeezed with the inner cavity of the docking support plate 11 through the guiding rotating groove 13, one end of the plug-in wire 36 away from the pressure-sensing end 35 extends into the protective rotating shell 14 through the through hole, and the outer surface of the alarm 37 is rotatably connected to the inner wall of the arc guiding rail 12.

[0018] On one side of the inner cavity of the docking support plate 11 away from the arc-shaped guide rail 12, a displacement chute 15 is provided. The inner wall of the displacement chute 15 is provided with a vertical push plate 17. The top of the vertical push plate 17 is fixedly connected with a control motor 18. The top of the output shaft of the control motor 18 is fixedly connected with a cutting tool head 19. The bottom of the vertical push plate 17 is fixedly connected with a control slide plate 16. The control slide plate 16 can drive the vertical push plate 17 to slide along the displacement chute 15, so as to adjust the cutting point of the cutting tool head 19. The upper surface of the control slide plate 16 is slidably connected with the lower surface of the docking support plate 11 through rollers. The bottom end of the vertical push plate 17 extends into the control slide plate 16. The outer surface of the vertical push plate 17 is slidably connected with the inner cavity of the docking support plate 11 through the displacement chute 15, and both the upper and lower ends of the vertical push plate 17 extend outside the displacement chute 15. The number of docking support plates 11 is two, the number of protective rotating shells 14 is two, the lower surface of the docking support plate 11 is fixedly connected to the ground, the number of pressure-sensitive ends 35 is two, and the bottom end of the pressure-sensitive end 35 is squeezed against the inner wall of the lower cover shell 33.

[0019] When using this device for milling work on S-shaped pipes, each section of the S-shaped pipe is placed into the interior of the device through the transfer devices 2 on both sides, and then the pipe body is lifted upward in a flat position by the clamping device inside. At this time, the pipe body passes through the calibration device 3 along the mating cutting groove 34 of the lower cover shell 33 and the upper cover shell 31. Since the mating cutting groove 34 is located at the axis of the device, the S-shaped pipe that can successfully pass through the mating cutting groove 34 is also clamped at the axis position at this time. Otherwise, the pipe body cannot pass through the mating cutting groove 34 and needs to perform a sliding adjustment operation.

[0020] When the S-shaped pipe passes through the mating cutting groove 34 of the cover shell, if the axis bending point of the S-shaped pipe does not face the axis bending point of the mating cutting groove 34, the S-shaped pipe will not be able to pass through the mating cutting groove 34 of the lower cover shell 33 at this time. Then, during the upward pushing process, the S-shaped pipe will exert an upward squeezing force on the lower cover shell 33. At this time, the lower cover shell 33 will exert an upward squeezing force on the compression gasket 32, thereby pressing the internal pressure-sensitive end 35, and then triggering the alarms 37 on both sides. At this time, the S-shaped pipe is no longer pushed upward. After fine-tuning the position of the S-shaped pipe, it is pushed upward for transfer until the S-shaped pipe can successfully pass through the mating cutting groove 34.

[0021] Example 2, please refer to Figures 1 - 7The present invention provides a technical solution: on the basis of embodiment 1, the transfer equipment 2 includes a fixed chassis 21, a control turntable 22 is rotatably connected at the axis center of the upper surface of the fixed chassis 21, a roller push box 23 is symmetrically arranged on the upper surface of the control turntable 22, and a side clamping plate 24 is slidably connected to the top of the inner wall of the control turntable 22. The roller push box 23 can drive the lower part of the side clamping plate 24 to perform vertical sliding movement through the self-rotating roller of the inner wall, thereby adjusting the horizontal height of the side top end, and can also change the distance between the side clamping plates 24 on both sides by horizontally moving the top shell, thereby achieving a clamping effect. The inner wall of the side clamping plate 24 is provided with a processing S tube 25, and the side clamping plates 24 on both sides can clamp the side parts of the end of the processing S tube 25, such as Figure 6 As shown, since both ends of the adapting groove 34 are expanded, when the side clamping plate 24 slides vertically upward under the control of the roller push box 23, the side clamping plates 24 on both sides and the processing S tube 25 can penetrate the adapting groove 34, and the feeding bin 4 is symmetrically arranged on both sides of the upper surface of the fixed chassis 21. The top of the side clamping plate 24 penetrates the outside of the upper cover shell 31 through the adapting groove 34, the number of roller push boxes 23 is two, and the lower surface of the roller push box 23 is fixedly connected to the upper surface of the control turntable 22, and both ends of the outer surface of the processing S tube 25 are pressed against the inner wall of the side clamping plate 24.

[0022] The feeding bin 4 includes a side fixing plate 41, the upper surface of which is fixedly connected to an extended side box 43 through a support rod 42, and a push slide rod is slidably connected to the side of the inner cavity of the extended side box 43 away from the docking support plate 11 through a slide groove, and the end of the push slide rod away from the docking support plate 11 is fixedly connected to an external slide cylinder 44, and the end of the push slide rod close to the docking support plate 11 is fixedly connected to a vertical guide plate 45, and the end of the push slide rod can be extended to push the clamped S tube inwardly, and arc-shaped clamping plates 46 are symmetrically arranged on the upper and lower sides of the outer surface of the vertical guide plate 45 through claws, and the arc-shaped clamping plates 46 on both sides can first clamp the end of the placed S tube, and then push it to the side clamping plate 24 to realize the work of transporting the tube body. Since the arc-shaped clamping plates 46 are vertically symmetrically arranged and staggered with the side clamping plates 24 symmetrically arranged on the left and right, there will be no work obstruction problem. The outer surface of the external slide 44 is slidably connected to the outer surface of the extended side box 43, the outer surface of the arc clamping plate 46 is slidably connected to the outer surface of the vertical guide plate 45, and the inner cavity of the extended side box 43 is symmetrically provided with feed cutting grooves on one side close to the docking support plate 11, and the lower surface of the side fixed plate 41 is fixedly connected to the upper surface of the fixed chassis 21.

[0023] The S-tube that has successfully passed through the housing is adjusted in vertical height under the action of relevant clamping components. Subsequently, after adjusting to a height suitable for the cutting heads 19 on both sides, the control turntable 22 at the bottom twists the roller shaft push boxes 23 on both sides, and drives the housing disc body to rotate around the guiding rotating groove 13 through the side clamping plates 24, thereby adjusting the end part of the S-tube so that the end part of the S-tube faces the cutting heads 19 on both sides. Since the bending degree of the tube body may vary, it is also necessary to adjust the cutting angle of the cutting head 19, that is, to control the sliding plate 16 to slide along the lower surface of the docking support plate 11, and control the cutting head 19 to slide by driving the vertical push plate 17 to slide along the displacement sliding groove 15, changing the cutting position of the cutting head 19 relative to the S-tube. Then, the cutting head 19 is pushed towards the S-tube along the displacement sliding groove 15, thereby realizing the milling work on the inner wall of the S-tube.

[0024] When the calibration device 3 rotates with the S-tube, the plug-in wire 36 will also pull the alarm 37 and the protective housing 14 to rotate in a circle along the merged arc-shaped guiding rails 12 on both sides, so as to ensure that the plug-in wire 36 will not hinder the rotation of the calibration device 3.

[0025] When performing the feeding work, the solid processed S-tube 25 is placed flat inside the extended side box 43 through the cutting slots on both sides of the extended side box 43. Then, one end of the processed S-tube 25 is inserted between the arc-shaped clamping plates 46. Subsequently, the vertical guiding plate 45 drives the arc-shaped clamping plates 46 on both sides to clamp the end part of the processed S-tube 25. Then, the processed S-tube 25 is moved towards the side clamping plate 24 by the pushing slide rod until the other end of the processed S-tube 25 is clamped by the side clamping plates 24 on both sides. Subsequently, the vertical guiding plate 45 is retracted, and the other end of the processed S-tube 25 is clamped by the remaining pair of side clamping plates 24. As Figure 6 shown, at this time, it is ready to push the processed S-tube 25 vertically upward.

[0026] When the processed S-tube 25 cannot pass through the fitting cutting slot 34, the side clamping plate 24 is pulled down to release the clamping work of one end of the side clamping plate 24. The processed S-tube 25 is advanced in the horizontal plane by the arc-shaped clamping plate 46. After the fine adjustment of the tube body is realized, the clamping and pushing work of the tube body is carried out. Subsequently, the tube body can pass through the fitting cutting slot 34, thereby realizing the calibration work, ensuring that the S-tube is at the axis position at this time. When its two ends rotate, they will always rotate around the axis, so that the symmetric cutting heads 19 on both sides can carry out effective milling work at the same time.

[0027] Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art and related fields based on the embodiments of the present invention without creative efforts shall fall within the scope of protection of the present invention.
