Description

Technical Field

[0001] This utility model relates to the field of chamfering technology, specifically to an internal and external chamfering processing device. Background Technology

[0002] Chamfering of internal and external parts is mainly done on pipe ends. When chamfering pipe parts, the pipe part needs to be pushed towards the chamfering tool. There are two ways to push the pipe part: manual and mechanical. Compared with manual, mechanical pushing has better pushing force and stability.

[0003] On internal and external chamfering processing equipment equipped with a mechanical pushing structure, the pushing structure and the chamfering structure are often separate structures with weak structural correlation, which limits the function of the pushing structure.

[0004] The newly designed internal and external chamfering processing equipment integrates the pushing structure with the chamfering structure, achieving mechanical pushing while also providing a certain level of safety protection. Utility Model Content

[0005] (I) Technical Issues

[0009] A corresponding follow-up feeding mechanism is provided on the front side of the box frame for each set of power plates. The follow-up feeding mechanism is used to clamp the pipe and drive the pipe to move forward and approach the inner chamfered part or the outer chamfered part when the power plate rotates.

[0012] The front end of the internally threaded cylinder is mounted through the front wall of the fixed frame and is rotatably connected to the fixed frame, while the rear end of the internally threaded cylinder is fixedly connected to the power plate.

[0013] The rear end of the external threaded cylinder extends into the internal threaded cylinder and engages with it threadedly, and the clamp is fixed at the front end of the external threaded cylinder;

[0014] Meanwhile, a rearwardly extending limiting rod is fixed to the outer side of the rear wall of the clamp near the telescopic cylinder assembly, and the limiting rod is slidably connected to the fixing frame.

[0015] Preferred technical solution 3: The tail end of the internal threaded cylinder is connected to the power plate through an annular mesh frame.

[0029] 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.

[0030] Please refer to the figure. Figure 2 , Figure 3 The internal and external chamfering processing equipment includes a frame 1. Two sets of power plates 2 are rotatably mounted on the front side of the frame 1. The center of the two sets of power plates 2 is used to fix the internal chamfering tool 3 and the external chamfering tool 4, respectively. Both the internal chamfering tool 3 and the external chamfering tool 4 are tapered structures (the specific structures adopt existing technologies, such as the tapered cutting end in the internal hole chamfering assembly and the external circle chamfering assembly in CN222326884U).

[0031] A corresponding follow-up feeding mechanism 5 is provided on the front side of the frame 1, corresponding to each set of power disks 2. The follow-up feeding mechanism 5 is used to clamp the pipe and drive the pipe to move forward and approach the inner chamfered part or the outer chamfered part when the power disk 2 rotates. Specifically:

[0032] The follow-up feeding mechanism 5 includes a fixed frame 51, which is fixed on the box frame 1 and its front wall is located in front of a corresponding set of power discs 2. A telescopic cylinder assembly 52 is installed on the front side wall of the fixed frame 51, and a clamping plate 54 (the clamping plate 54 adopts existing technology and can be an electric clamping plate or a manual clamping plate) is fixed at the front end of the telescopic cylinder assembly 52. ​​The tail end is connected to the power disc 2 and surrounds the inner chamfering cutter 3 and the outer chamfering cutter 4. The pipe passes through the telescopic cylinder assembly 52 and is clamped and fixed by the clamping plate 54. When the power disc 2 rotates, it will drive the telescopic cylinder assembly 52 to extend or retract, thereby driving the pipe clamped by the clamping plate 54 to feed to the inner chamfering cutter 3 or the outer chamfering cutter 4.

[0033] In one set of embodiments

[0034] Please see Figure 1 , Figure 3 , Figure 4The telescopic cylinder assembly 52 includes an internally threaded cylinder 521 and an externally threaded cylinder 522. The front end of the internally threaded cylinder 521 is mounted through the front wall of the fixed frame 51 and is rotatably connected to the fixed frame 51. At the same time, the rear end of the internally threaded cylinder 521 is fixedly connected to the power plate 2. The rear end of the externally threaded cylinder 522 extends into the internally threaded cylinder 521 and engages with it threadedly. The clamp 54 is fixed at the front end of the externally threaded cylinder 522. The centers of the internally threaded cylinder 521, the externally threaded cylinder 522, the clamp 54, and the power plate 2 are all located on the same straight line, thereby ensuring that the axis of the pipe can coincide with the axis of the internal chamfering tool 3 or the external chamfering tool 4.

[0035] A rearwardly extending limiting rod 53 is fixed on the rear wall of the chuck 54 near the outer side of the telescopic cylinder assembly 52. ​​The limiting rod 53 is slidably connected to the fixing frame 51, that is, the limiting rod 53 is slidably inserted into the hole opened in the front wall of the fixing frame 51. Through the sliding connection between the limiting rod 53 and the fixing frame 51, the external threaded cylinder 522 is limited, so that when the internal threaded cylinder 521 rotates, the external threaded cylinder 522 will not rotate with it, but will move back and forth (the chamfering process controls the feeding speed of the pipe fitting by configuring the pitch on the internal threaded cylinder 521 and the external threaded cylinder 522).

[0036] In one set of embodiments

[0037] Please see Figure 2 , Figure 4 The end of the internal threaded cylinder 521 is connected to the power plate 2 through an annular mesh frame 55. That is, the front end of the mesh frame 55 is fixedly sleeved on the end of the internal threaded cylinder 521, while the rear end is fixedly connected to the power plate 2. The corresponding internal chamfering tool 3 or external chamfering tool 4 on the power plate 2 is located inside the mesh frame 55 (achieving safety protection for the internal chamfering tool 3 or external chamfering tool 4 without affecting the discharge of chips). The mesh frame 55 not only connects the internal threaded cylinder 521 and the power plate 2, but also allows chips to be exposed during chamfering through the gaps on the mesh frame 55.

[0038] In use, the pipe is passed through the inner threaded cylinder 521 and the outer threaded cylinder 522 (the inner diameter of the outer threaded cylinder 522 is larger than the diameter of the pipe, so that the pipe can easily extend and retract from the inner threaded cylinder 521 and the outer threaded cylinder 522). The end of the pipe is close to the power plate 2 and in contact with the inner chamfering tool 3 or the outer chamfering tool 4. The pipe is clamped by the chuck 54. When the power plate 2 rotates, the power plate 2 will drive the inner threaded cylinder 521 to rotate synchronously, so that the outer threaded cylinder 522 moves back and forth, moving closer or further away from the power plate 2. When the power plate 2 rotates forward, it will drive the pipe to move backward and further closer to the inner chamfering tool 3 or the outer chamfering tool 4 to complete the inner chamfering or outer chamfering. After the chamfering is completed, the pipe can be moved forward by flipping the power plate 2. Then the clamping state of the chuck 54 can be released and the pipe can be taken out. The pipe is then operated alternately between the inner chamfering tool 3 and the outer chamfering tool 4 to achieve the inner and outer chamfering.

[0039] In one set of embodiments

[0040] Please see Figure 1 , Figure 2 , Figure 3 The shaft 21 at the center of the power disc 2 extends into the housing 1; there is also a power assembly 6 inside the housing, which includes a drive motor 61 fixed in the housing 1. A transmission belt (not shown in the figure) is sleeved between the pulley 62 fixed on the output shaft of the drive motor 61 and the pulley 62 fixed on the shaft 21. Power is transmitted by the transmission belt. The pulley 62 and the transmission belt are selected with anti-slip structure. At the same time, a dust cover 63 is also installed in the housing to cover the pulley 62 and the transmission belt.

The circuits, electronic components, and modules involved are all existing technologies, which can be fully implemented by those skilled in the art, and need not be elaborated upon.
