Description

Technical Field

[0001] This utility model relates to the field of chamfering technology, and more specifically, to equipment for chamfering joints. Background Technology

[0002] Chamfering equipment is a specialized machine tool or tool used to chamfer the edges of workpieces (i.e., remove sharp edges to form bevels or arcs). It uses a rotating milling cutter to cut the edges of the workpiece and is suitable for precise chamfering of materials such as metals and plastics. It eliminates sharp burrs after cutting or stamping, prepares for welding, such as pipe beveling, and makes the edges of the workpiece smooth, avoiding scratches.

[0003] Chinese Patent Publication No. CN219426242U discloses a wire tube chamfering device. This solution uses a positioning mechanism on the clamping mechanism to axially position the end of the wire tube, avoiding the problem of wire tube shifting back and forth due to unsatisfactory positioning, resulting in irregular chamfering and improving the pass rate of wire tube chamfering. The clamping mechanism is driven by a hydraulic cylinder to clamp the wire tube, making the wire tube firmly fixed and preventing the wire tube from loosening and rotating with the tool, which would damage the threads on the surface of the wire tube and improve product quality.

[0004] Hardware used for water pipe connections usually has irregular flat surfaces or threads for connection. Water pipe connectors are also made of materials such as plastic. The clamps used for chamfering in the above solution are used to apply pressure to the outer surface of the workpiece for fixation. For workpieces with irregular outer surfaces and plastic workpieces, clamping on the outer surface can easily cause chipping or scratches, thereby damaging the processed workpiece.

[0005] Therefore, a joint chamfering processing equipment is proposed to address the above problems. Utility Model Content

[0038] 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. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0039] Please see Figure 1 - Figure 6 The joint chamfering processing equipment includes a mounting frame 1 and a movable support plate 3. A fixed support plate 2 is fixedly mounted on the top of the mounting frame 1. An adjusting component 7 is provided on the top of the movable support plate 3. A rotating shaft 6 is rotatably mounted on the top of the adjusting component 7, and a drive motor 5 is mounted on the top of the adjusting component 7. A fixed plate 10 is fixedly mounted on the top of the fixed support plate 2 through two fixed blocks 11. A bracket 12 is fixedly connected to the top of the fixed plate 10. An inner support component 8 is provided on the top of the bracket 12. The inner support component 8 includes a driving gear 83 and three driven gears 84. A connecting rod 85 is fixedly mounted on the outer end of each of the three driven gears 84. The outer end of the driving gear 83 is meshed with the three driven gears 84. The driving gear 83 drives the three driven gears 84 to drive the connecting rod 85 to rotate by rotating. The inner support component 8 also includes a worm gear 89 and a worm 810. The worm 810 and the worm gear 89 are meshed with each other. The driving gear 83 is fixedly connected to the worm gear 89.

[0040] The mounting platform 1 is equipped with a moving device 4 on top for adjusting the position of the movable support plate 3. One end of the rotating shaft 6 is detachably connected to a cutter head 9. The drive motor 5 and the rotating shaft 6 are connected by belt drive.

[0041] The device in this solution is mainly used for chamfering the connector joints of water pipes. Since the surface of the water pipe connectors may have irregular planes and threads, or be made of plastic, the traditional external clamping chamfering fixture is prone to damaging the outer surface. However, the inner wall of the water pipe connector is smooth. Therefore, this solution uses an internal support component 8 to fix the connector in an internal support manner, which can prevent damage to the workpiece during chamfering.

[0042] A fixed support plate 2 is fixed on the top of the mounting frame 1. The fixed support plate 2 is immovable. Two fixed blocks 31 are fixed on the top of the fixed support plate 2. A fixed plate 10 is fixed between the two fixed blocks 311. A bracket 12 is fixed on the top of the fixed plate 10. The inner support assembly 8 is fixed to the top of the bracket 12 by bolts. The bracket 12 is mainly used to raise the height of the inner support assembly 8. The workpiece is placed on the three friction sleeves 87. Then, the worm gear 810 is rotated by the rotating wheel 88, so that the worm wheel 89 drives the driving gear 83 to rotate. At this time, the three meshing passive gears 84 drive the inner support column 86 to rotate outward at the same time, so that the friction sleeve 87 is tightly pressed against the inner wall of the workpiece, thus forming an internal support fixing method from the inside, which can prevent damage to the outer surface of the workpiece during chamfering.

[0043] A moving device 4 is installed on top of the mounting frame 1, and a movable pallet 3 is installed on top of the moving device 4. The moving device 4 is mainly used to adjust the distance between the movable pallet 3 and the fixed pallet 2 so that it can be used for workpieces of different lengths. The moving device 4 is mainly composed of a screw and two crossbars. The screw is rotatably installed on the top of the mounting frame 1, and a screw sleeve is fixed at the bottom of the movable pallet 3. The two crossbars are fixed on the mounting frame 1. At the same time, the movable pallet 3 is slidably connected to the crossbars through a sliding sleeve fixed at the bottom. When the screw is rotated, it can drive the screw sleeve to move the movable pallet 3 along the crossbars to adjust the distance between it and the fixed pallet 2.

[0044] At the top of the movable pallet 3, the distance adjustment assembly 7 is installed. The drive motor 5 is fixedly installed on the top of the movable plate 73 in the distance adjustment assembly 7. The drive motor 5 is mounted above the rotating shaft 6 via a mounting bracket. The rotating shaft 6 is also rotatably mounted on the movable plate 73. The output end of the drive motor 5 is keyed to a pulley, and a pulley is also installed at one end of the rotating shaft 6. The drive motor 5 can drive the rotating shaft 6 to rotate via belt drive. The other end of the rotating shaft 6 is detachably connected to the cutter head 9. The inner support assembly 8 and the cutter head 9 are coaxially arranged. By driving the cutter head 9 to rotate, the workpiece can be chamfered.

[0045] Please see Figure 2The adjustable distance assembly 7 includes a mounting platform 72 and a movable plate 73. The mounting platform 72 is fixedly installed on the top of the movable support plate 3. A slider is fixedly installed on the bottom of the movable plate 73. A sliding groove adapted to the slider is opened on the inner side of the mounting platform 72. The mounting platform 72 and the movable plate 73 are slidably connected. The drive motor 5 is fixedly installed on the top of the movable plate 73. The rotating shaft 6 is rotatably installed on the top of the movable plate 73.

[0046] The adjustable distance assembly 7 also includes a cylinder 71 and two slide rods 74. The cylinder 71 is fixedly installed at the outer end of the mounting platform 72. The output end of the cylinder 71 is connected to the movable plate 73 and drives it to move. The slide rods 74 are fixedly installed between the mounting platform 72 and the fixed block 11, and the slide rods 74 pass through the movable plate 73. The fixed block 11 is fixedly installed on the top of the fixed support plate 2.

[0047] In this design, the adjustable distance assembly 7 is mainly used to drive the drive motor 5 and the rotating shaft 6 to move. The mounting platform 72 is fixed on the movable support plate 3, so that the adjustable distance assembly 7 can move with the movable support plate 3. A sliding groove is opened on the inner side of the mounting platform 72, and a slider is fixed at the bottom of the movable plate 73. The movable plate 73 can slide and connect with the sliding groove on the inner side of the mounting platform 72 through the slider at the bottom. A cylinder 71 is fixed on the outer side of the mounting platform 72. The cylinder 71 needs to be connected to an external pneumatic working system to provide power and perform precise control. The output end of the cylinder 71 passes through the side wall of the mounting platform 72 and is fixedly connected to the movable plate 73, so that it can drive the movable plate 73.

[0048] Two fixed blocks 311 are fixed on the fixed support plate 2. The two ends of the slide rod 74 are fixedly connected to the fixed blocks 311 and the inner side of the mounting platform 72 respectively. At the same time, the slide rod 74 passes through the movable plate 73, so that the movable plate 73 and the slide rod 74 are slidably connected. When the drive motor 5 drives the rotating shaft 6 and the cutter head 9 to rotate through the belt and pulley, the cylinder 71 can push the drive motor 5 and the rotating shaft 6 to move as a whole towards the inner support assembly 8. Since the workpiece is fixed on the inner support assembly 8, when the cylinder 71 pushes the cutter head 9 to contact the workpiece, it can be chamfered, thus completing the chamfering work.

[0049] Please see Figure 3 - Figure 6 The inner support assembly 8 also includes a housing 82, which is fixedly installed on the top of the bracket 12. Three connecting rods 811 are fixedly connected to the outer end of the housing 82. A clamping plate 81 is fixedly installed on the outer end of the connecting rods 811. The driving gear 83 and three driven gears 84 are located between the clamping plate 81 and the housing 82.

[0050] An inner support column 86 is fixedly connected to the outer end of the connecting rod 85. A friction sleeve 87 is sleeved on the outer end of the inner support column 86. The friction sleeve 87 abuts against the inner wall of the workpiece. Three driven gears 84 are rotatably connected to three connecting rods 811 respectively.

[0051] Both the worm gear 89 and the worm 810 are located inside the housing 82. The worm gear 89 is rotatably mounted inside the housing 82. One end of the worm 810 is rotatably connected to the inner wall of the housing 82, and the other end of the worm 810 extends through the side wall of the housing 82 to the outside. A rotating wheel 88 is fixedly connected to one end of the worm 810. The driving gear 83 drives the three driven gears 84 to rotate through the worm gear 89.

[0052] The inner support assembly 8 in this scheme is mainly used to fix the workpiece being processed, so that it can be chamfered stably. The housing 82 can be fixed to the bracket 12 by bolts. Three connecting rods 811 are fixedly installed on the outer end of the housing 82. Three driven gears 84 are rotatably connected to the three connecting rods 811, so that the three driven gears 84 can rotate on the outer end of the housing 82. A connecting rod 85 is fixed on the outer end of each driven gear 84. The connecting rod 85 extends outward. An inner support column 86 is fixedly installed on the outer end of the connecting rod 85. The inner support column 86 is columnar, and a friction sleeve 87 is sleeved on the outer end of each inner support column 86. The friction sleeve 87 is made of rubber, so that it has a large friction force. The clamping plate 81 covers the outer end of the three driven gears 84 and is fixedly installed on the outer end of the housing 82 by the three connecting rods 811.

[0053] A worm gear 89 is rotatably mounted inside the housing 82, and a drive gear 83 is fixed to the outer end of the worm gear 89. The drive gear 83 is located in the gap between the housing 82 and the clamping plate 81 and meshes with three driven gears 84 simultaneously, so that it can drive the three driven gears 84 to rotate at the same time. A worm 810 is placed horizontally inside the housing 82. One end of the worm 810 is rotatably connected to the inner wall of the housing 82, and the other end extends through the side wall of the housing 82 to the outside and is fixedly mounted with a rotating wheel 88. At the same time, the worm 810 and the worm gear 89 are meshed together.

[0054] When it is necessary to fix the workpiece, the workpiece can be first placed on the outer end of the three friction sleeves 87. Then, rotate the rotating wheel 88 to make the worm 810 drive the worm wheel 89 to rotate. The rotating worm wheel 89 will drive the driving gear 83 to mesh with the three driven gears 84. The driven gears 84 driven by the driving gear 83 will drive the connecting rod 85 to rotate outward, so that the inner support column 86 drives the friction sleeve 87 to press tightly against the inner wall of the workpiece, thereby forming an inner support fixation of the inner wall of the workpiece.

[0055] Working principle: When using this device, the workpiece is first fixed on the inner support assembly 8, and the workpiece is placed on the outer end of the three friction sleeves 87. The rotating wheel 88 is rotated to drive the worm gear 810 to rotate the worm wheel 89. Then the driving gear 83 meshes with the three driven gears 84 and rotates. The rotating driven gears 84 will drive the connecting rod 85 to rotate outward, so that the inner support column 86 drives the friction sleeve 87 to press tightly against the inner wall of the workpiece. Then the drive motor 5 can be started to drive the rotating shaft 6 to rotate the cutter head 9. At this time, the cylinder 71 pushes the drive motor 5 and the rotating shaft 6 to move as a whole. When the cutter head 9 contacts the workpiece, it can be chamfered.
