Description

Technical Field

[0001] This utility model relates to the field of pipe end beveling technology, and in particular to an adaptive pipe end beveling device. Background Technology

[0002] In the existing technology, the internal expansion pipe beveling machine is the core model of pipe end beveling adaptive trimming equipment that focuses on the internal fixing of pipes. Its core function is to use the internal tensioning mechanism of the equipment to extend into the inner cavity of the pipe and automatically adapt to the pipe diameter to achieve stable centering, and then trim the pipe end.

[0003] A search revealed a utility model patent with Chinese patent publication number CN217370690U, which discloses an internal expansion pipe beveling machine, including a cutter carrier plate and an internal expansion beveling machine cutter. The bottom of the cutter carrier plate has multiple grooves extending to its side. Multiple mounting plates corresponding to the positions of the multiple grooves are installed on the side of the cutter carrier plate by screws. A second fixing rod is placed inside each of the multiple grooves. The two ends of the second fixing rod are respectively installed on the side of the mounting plate and the inner side of the groove by screws. Although the internal expansion pipe beveling machine described above allows the cutter to drive the movable tube to slide on the surface of the second fixed rod according to the irregularity of the pipe surface, and at the same time, the movable tube will pull or release the tension spring, thus facilitating the internal expansion beveling machine cutter to bevele non-standard round pipes, the cutter is slidably connected to the second fixed rod through the movable tube. During cutting, it relies on the elastic force of the tension spring to keep the cutter in contact with the pipe surface. However, the flexible support of the spring will cause the cutter to experience a brief force shift when it encounters a small protrusion on the pipe surface. Utility Model Content

The fixing plate is fixed to one side of the second wedge block.

[0010] As a further embodiment of this utility model: the driving mechanism includes a second mounting box, a tail cylinder, a motor, a drive gear, a driven gear, and a transmission rod, and the transmission rod is fixed to one side of the crossbar.

[0011] As a further embodiment of this utility model: the tail cylinder is rotatably connected to the outer wall of the transmission rod, the second mounting box is fixed to the outer wall of the tail cylinder, the motor is mounted on the inner wall of the second mounting box, the drive gear is fixed to the output end of the motor, the driven gear is fixed to one side of the transmission rod, and the drive gear meshes with the driven gear.

[0013] As a further embodiment of this utility model: one end of the spring is fixed to one side of the sleeve, and the spring is located on the inner wall of the clamping ring. The extrusion plate is slidably connected to the inner wall of the clamping ring, and the extrusion plate is fixedly connected to the other end of the spring. The extrusion plate is against one side of the cutting ring. The bracket is fixed to the outer surface of the tail cylinder. The screw is threadedly connected to the inner wall of the bracket. The push frame is rotatably connected to one side of the screw. The extrusion plate is fixed to one side of the push frame, and the extrusion plate is against the other side of the cutting ring. The connecting seat is fixed to the outer surface of the push frame. The guide rod is fixed to one side of the mounting box, and the guide rod is slidably engaged with the connecting seat.

[0014] Compared with the prior art, this utility model provides an adaptive pipe end beveling device, which has the following beneficial effects:

[0015] 1. When it is necessary to fix the equipment inside the pipe, the electric push rod is activated, pushing the push rod to move. The first wedge block moves synchronously. At this time, the inclined surface of the first wedge block presses against the inclined surface of the push rod, forcing the second wedge block to slide outward along the groove. At the same time, the fixing plate is pushed outward synchronously until the fixing plate abuts against the inner wall of the pipe. Thus, the pushing distance of the electric push rod can be adjusted according to the inner diameter of different pipes, thereby matching pipes with different inner diameters and reducing the time for replacing parts.

[0016] 2. When a bevel needs to be cut, start the motor. The motor drives the drive gear to rotate synchronously. At this time, the driven gear meshing with the drive gear rotates synchronously and transmits power to the transmission rod. The transmission rod then drives the crossbar to rotate, thereby driving the cutting ring to rotate. Thus, according to the gear ratio of the drive gear and the driven gear, the rotation speed of the crossbar can be reduced, while the torque can be amplified to increase the cutting force.

[0017] 3. When the tool cuts the pipe end, rotate screw two. Screw two moves axially along the inner wall of the support and drives the feed frame to move forward synchronously. At this time, the feed frame moves together, and the extrusion plate two presses against one side of the cutting ring, driving the cutting ring to move towards the pipeline. At the same time, the connecting seat moves along the outer wall of the guide rod. When the cutting ring moves, the other side will press the extrusion plate one, thereby compressing the spring in the jacket ring. When the spring is compressed, it generates a reverse elastic force. If it is necessary to reduce the feed, rotate screw two in the opposite direction. The feed frame and extrusion plate two move backward. At this time, the compressed spring releases its elastic force, pushing the extrusion plate one against the cutting ring to move in the opposite direction and return to the initial position. The inner wall of the feed frame does not contact the outer wall of the transmission rod, and the extrusion plate two does not contact the outer wall of the crossbar. This ensures that the feed of the feed frame does not affect the rotation of the transmission rod and the crossbar. Thus, the depth of the tool cut can be controlled, and the thread drive of screw two enables micro-feeding, which can achieve more precise operation.

[0018] The parts of this device not covered herein are the same as or can be implemented using existing technologies. This utility model has a simple structure and is easy to operate. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] In the description of this utility model, it should be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," "linking," and "setting" should be interpreted broadly. For example, they can refer to a fixed connection or setting, a detachable connection or setting, or an integral connection or setting. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] An adaptive pipe end beveling device, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the device includes a sleeve 1, with a mounting box 2 fixed to one side of the sleeve 1. A fixing mechanism 3 is provided inside the sleeve 1. A crossbar 9 is rotatably connected to one side of the sleeve 1. A cutting ring 4 is slidably connected to the outer wall of the crossbar 9, and a horizontal plate is installed on the outer surface of the cutting ring 4. A groove is provided on one side of the horizontal plate, and a slider 5 is slidably connected to the inner wall of the groove. A cutting tool is installed on one side of the slider 5. A screw 6 is fixedly connected to one side of the slider 5, and the screw 6 passes through the groove. A nut is rotatably connected to the outer surface of the screw 6. A driving mechanism 7 is provided on one side of the crossbar 9, and a feeding mechanism 8 is provided on the outer surface of the crossbar 9.

[0030] When the pipe is inserted into the sleeve 1, the fixing mechanism 3 inside the sleeve 1 is activated and presses against the inner wall of the pipe, fixing the device to the inner wall of the pipe. Then, according to the pipe bevel requirements, the screw 6 is turned to drive the slider 5 to slide in the groove of the cutting ring 4, so that the slider 5 moves to the preset position. Then, the drive mechanism 7 is activated, thereby driving the crossbar 9 to rotate, which in turn drives the cutting ring 4 to rotate synchronously, so that the tool makes a synchronous circular motion. While the cutting ring 4 is rotating, the feed mechanism 8 pushes the cutting ring 4 to move slowly along the axis of the crossbar 9, so that the tool gradually deepens the cutting depth. Thus, the fixing mechanism 3 can adapt to pipes with different inner diameters, improving the versatility of the device. At the same time, the drive mechanism 7 can amplify the torque while driving the crossbar 9 to increase the cutting force of the tool. Furthermore, the cutting ring 4 is fed by the feed mechanism 8. Under the push of the feed mechanism 8, the tool is closely pressed against the feed mechanism 8 by the reaction force of the sleeve 1, so as to ensure stable rigid support.

[0031] In order to adapt to the inner diameter of the pipe and fix the device inside the pipe, such as Figure 2 As shown, the fixing mechanism 3 includes an electric push rod 301, a push rod 302, a first wedge block 303, a second wedge block 304, and a fixing plate 305. The electric push rod 301 is fixed to one side of the mounting box 2, the push rod 302 is fixed to the output end of the electric push rod 301, and the push rod 302 passes through one side of the sleeve 1. The first wedge block 303 is fixed to the outer surface of the push rod 302. A groove is opened on the outer surface of the sleeve 1. The second wedge block 304 is slidably connected to the inner wall of the groove, and the second wedge block 304 is in contact with the inclined surface of the first wedge block 303. The fixing plate 305 is fixed to one side of the second wedge block 304.

[0032] When it is necessary to fix the equipment inside the pipe, the electric push rod 301 is activated, pushing the push rod 302 to move. The wedge block 303 moves synchronously. At this time, the inclined surface of the wedge block 303 presses against the inclined surface of the push rod 302, forcing the wedge block 304 to slide outward along the groove. At the same time, the fixing plate 305 is pushed outward synchronously until the fixing plate 305 abuts against the inner wall of the pipe. Thus, the pushing distance of the electric push rod 301 can be adjusted according to the inner diameter of different pipes, thereby matching pipes with different inner diameters and reducing the time for replacing parts.

[0033] In order to drive the crossbar 9 to rotate, thereby causing the cutting ring 4 to rotate synchronously, such as Figure 3 As shown, the drive mechanism 7 includes a second mounting box 701, a tail cylinder 702, a motor 703, a drive gear 704, a driven gear 705, and a transmission rod 706. The transmission rod 706 is fixed to one side of the crossbar 9. The tail cylinder 702 is rotatably connected to the outer wall of the transmission rod 706. The second mounting box 701 is fixed to the outer wall of the tail cylinder 702. The motor 703 is mounted on the inner wall of the second mounting box 701. The drive gear 704 is fixed to the output end of the motor 703. The driven gear 705 is fixed to one side of the transmission rod 706, and the drive gear 704 meshes with the driven gear 705.

[0034] When a bevel needs to be cut, the motor 703 is started. The motor 703 drives the drive gear 704 to rotate synchronously. At this time, the driven gear 705, which meshes with the drive gear 704, rotates synchronously and transmits power to the transmission rod 706. The transmission rod 706 then drives the crossbar 9 to rotate, thereby driving the cutting ring 4 to rotate. Thus, according to the gear ratio of the drive gear 704 and the driven gear 705, the rotation speed of the crossbar 9 can be reduced, while the torque can be amplified to increase the cutting force.

[0035] In order to enable the cutting ring 4 to bevel the pipe end, such as Figure 4 , Figure 5 and Figure 6 As shown, the feeding mechanism 8 includes a clamping ring 801, a spring 802, a first extrusion plate 803, a second extrusion plate 804, a pusher frame 805, a bracket 806, a second screw 807, a connecting seat 808, and a guide rod 809. The clamping ring 801 is fixed to one side of the sleeve 1, one end of the spring 802 is fixed to one side of the sleeve 1, and the spring 802 is located on the inner wall of the clamping ring 801. The first extrusion plate 803 is slidably connected to the inner wall of the clamping ring 801, and the other end of the first extrusion plate 803 is fixedly connected to the other end of the spring 802. The extrusion plate 803 is attached to one side of the cutting ring 4. The bracket 806 is fixed to the outer surface of the tail cylinder 702. The screw 807 is threadedly connected to the inner wall of the bracket 806. The push frame 805 is rotatably connected to one side of the screw 807. The extrusion plate 804 is fixed to one side of the push frame 805 and is attached to the other side of the cutting ring 4. The connecting seat 808 is fixed to the outer surface of the push frame 805. The guide rod 809 is fixed to one side of the mounting box 701 and slides with the connecting seat 808.

[0036] When the tool cuts the pipe end, the screw 807 is rotated, causing it to move axially along the inner wall of the bracket 806 and simultaneously moving the feed frame 805 forward. At the same time, the feed frame 805 moves along with the screw, and the extrusion plate 804 presses against one side of the cutting ring 4, driving it to move towards the pipe. Simultaneously, the connecting seat 808 moves along the outer wall of the guide rod 809. As the cutting ring 4 moves, the other side presses against the extrusion plate 803, thereby compressing the spring 802 inside the jacket ring 801. The spring 802 generates a reverse elastic force when compressed. If a reduction in feed rate is needed, the screw is rotated in the opposite direction. When the second screw 807, the feed frame 805, and the second extrusion plate 804 retract, the compressed spring 802 releases its elastic force, pushing the first extrusion plate 803 against the cutting ring 4 to move in the opposite direction and return to its initial position. The inner wall of the feed frame 805 does not contact the outer wall of the transmission rod 706, and the second extrusion plate 804 does not contact the outer wall of the crossbar 9. This ensures that the feed of the feed frame 805 does not affect the rotation of the transmission rod 706 and the crossbar 9. As a result, the depth of cut of the tool can be controlled, and the thread drive of the second screw 807 enables micro-feeding, allowing for more precise operation.

[0037] Working principle: When the pipe is inserted into the sleeve 1, the fixing mechanism 3 inside the sleeve 1 is activated and presses against the inner wall of the pipe, fixing the device to the inner wall of the pipe. Then, according to the pipe bevel requirements, the screw 6 is turned to drive the slider 5 to slide in the groove of the cutting ring 4, moving the slider 5 to the preset position. Then, the drive mechanism 7 is activated, thereby driving the crossbar 9 to rotate, which in turn drives the cutting ring 4 to rotate synchronously, so that the tool makes synchronous circumferential motion. While the cutting ring 4 is rotating, the feed mechanism 8 pushes the cutting ring 4 to move slowly along the axial direction of the crossbar 9, so that the tool gradually deepens the cutting depth.

[0038] When it is necessary to fix the equipment inside the pipeline, the electric push rod 301 is activated, pushing the push rod 302 to move. The wedge block 303 moves synchronously. At this time, the inclined surface of the wedge block 303 presses against the inclined surface of the push rod 302, forcing the second wedge block 304 to slide outward along the groove. Simultaneously, the fixing plate 305 is pushed outward until the fixing plate 305 abuts against the inner wall of the pipeline.

[0039] When beveling is required, motor 703 is started, which drives drive gear 704 to rotate synchronously. At the same time, driven gear 705, which meshes with drive gear 704, rotates synchronously and transmits power to transmission rod 706. Transmission rod 706 then drives crossbar 9 to rotate, thereby causing cutting ring 4 to rotate.

[0040] When the tool cuts the tube end, the screw 807 is rotated, causing it to move axially along the inner wall of the bracket 806 and simultaneously moving the pusher 805 forward. At this time, the pusher 805 moves along with the screw, and the extrusion plate 804 presses against one side of the cutting ring 4, driving the cutting ring 4 towards the pipeline. Simultaneously, the connecting seat 808 moves along the outer wall of the guide rod 809. As the cutting ring 4 moves, the other side presses against the extrusion plate 803, thereby compressing the spring 802 inside the jacket ring 801. 2. During compression, a reverse elastic force is generated. If it is necessary to reduce the feed rate, the screw 807 is rotated in the reverse direction, and the pusher 805 and the extrusion plate 804 are retracted. At this time, the compressed spring 802 releases its elastic force, pushing the extrusion plate 803 to move in the opposite direction against the cutting ring 4 and return to the initial position. The inner wall of the pusher 805 does not contact the outer wall of the transmission rod 706, and the extrusion plate 804 does not contact the outer wall of the crossbar 9, so that the feed of the pusher 805 does not affect the rotation of the transmission rod 706 and the crossbar 9.

[0041] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
