The synchronous drive mechanism 300 is arranged on both sides of the inner and outer sides of the pipe fitting 3, and moves synchronously along the axial direction of the pipe fitting 3 when working; the adaptive grinding mechanism 400 is installed on the positioning cross bar 15 and the movable block 20 in the synchronous drive mechanism 300, and the movable block 20 is elastically and movably installed with a longitudinal shaft 28, and the end of the longitudinal shaft 28 is fixedly connected with a grinding head 29, and the grinding head 29 abuts against the inner wall of the pipe fitting 3; the adaptive grinding mechanism 400 moves synchronously with the synchronous drive mechanism 300, and adjusts the position of the grinding head 29 during the movement, so as to simultaneously remove burrs on both sides of the inner and outer sides of the pipe fitting 3.

[0016] In one example of the present invention, an auxiliary support assembly is also included, which includes a support 131, a transverse axis 132 and a roller 133; a plurality of rollers 133 are provided, and a transverse axis 132 is fixedly installed in the middle of the roller 133; the transverse axis 132 is rotatably connected to the external support 131 to prevent shaking when the pipe 3 rotates.

[0017] like Figure 1 , Figure 2 and Figure 3 As shown, as a preferred embodiment of the present invention, the external tightening mechanism 100 includes a guide column 4, a tightening block 5, a limiting rod 6 and an elastic support member 7; The guide column 4 is slidably mounted on the fixing frame 2, a tightening block 5 is fixedly mounted on one end of the guide column 4, and a limiting rod 6 is fixedly mounted on the other end of the guide column 4; An elastic support member 7 is sleeved on the guide column 4 between the fixing frame 2 and the limiting rod 6 to fix the outer side of the pipe 3 .

[0018] In one embodiment of the present invention, the inclined surface of the tightening block 5 is a slope surface, so as to smoothly tighten the pipe fitting 3; when installing the pipe fitting 3, the inclined surface of the tightening block 5 is a slope surface, so as to smoothly tighten the pipe fitting 3; Figure 1Taking the pipe 3 as a reference, the pipe 3 is pushed from the left side to the right side, and the clamping block 5 is forced to push the guide column 4 to slide along the fixing frame 2. The elastic support member 7 is elastically deformed under the force, and after the pipe 3 moves to the specified position, the clamping work on the outer side of the pipe 3 is realized by the clamping block 5 under the action of the elastic support member 7.

[0019] like Figure 1 As shown, as another preferred embodiment of the present invention, the inner tightening mechanism 200 includes a sleeve 8, a guide rod 9, an abutting head 10, a pull rope 11 and a pull ring 12; The sleeve 8 is fixedly mounted on the end of the driving shaft 1, a guide rod 9 is elastically mounted on the sleeve 8, a tightening head 10 is fixedly connected to the end of the guide rod 9, and the tightening head 10 abuts against the inner wall of the pipe 3; A pull rope 11 is installed in the driving shaft 1 , one end of the pull rope 11 is connected to the inner end of the guide rod 9 , and a pull ring 12 is arranged at the other end of the pull rope 11 .

[0020] In one embodiment of the present invention, when placing the pipe 3 on the driving shaft 1, the pull ring 12 is pulled outward, and the pull ring 12 drives the guide rod 9 and the clamping head 10 to slide along the sleeve 8 through the set pull rope 11. After the installation of the pipe 3 is completed, the set pull ring 12 is released, and the guide rod 9 moves outward in the opposite direction under the action of the built-in micro elasticity, and the clamping head 10 is used to fix the inner side of the pipe 3; in addition, the number of guide rods 9 and the clamping head 10 arranged in the present application can be adjusted synchronously according to the number of ends of the sleeve 8, except for the use of the attached manual Figure 1 In addition to the two shown in the specification, you can also use the Figure 4 The specific number of the four shown can be adjusted as needed and will not be described in detail here.

[0021] like Figure 1 As shown, as another preferred embodiment of the present invention, the synchronous drive mechanism 300 includes a side plate 14, a positioning cross bar 15, a driving screw 16, a pulley 17, a synchronous belt 18, a rotating motor 19 and a movable block 20; The side plate 14 is arranged at the end of the pipe 3, and two positioning cross bars 15 are fixedly installed on the side of the side plate 14, and movable blocks 20 are slidably installed on the two positioning cross bars 15; The movable block 20 is driven by a driving screw 16 rotatably arranged on the side plate 14, a pulley 17 is mounted on the driving screw 16, and adjacent pulleys 17 are connected by a synchronous belt 18; The driving screw 16 on one side is connected to the shaft end of the external rotating motor 19 through a coupling.

[0022] In one example of the present invention, when the rotating motor 19 is working, it can drive the driving screw 16 on one side to rotate along the side plate 14 through the coupling, and the driving screw 16 can also drive the driving screw 16 on the other side to rotate synchronously through the arranged pulley 17 and the synchronous belt 18. The driving screws 16 on both sides work synchronously to push the movable block 20 at the corresponding position to slide along the positioning cross bar 15. In this process, the adaptive grinding mechanism 400 moves synchronously therewith.

[0023] like Figure 1 and Figure 5 As shown, as another preferred embodiment of the present invention, the adaptive grinding mechanism 400 includes a concave tooth portion 21, a bracket 22, a driving shaft 23, a driven bevel gear 24, a driving bevel gear 25, a driving gear 26 and a driven gear 27; The concave tooth portion 21 is arranged on the positioning cross bar 15, a bracket 22 is fixedly installed on the side of the movable block 20, a driving shaft 23 is rotatably installed on the top end of the bracket 22, a driven bevel gear 24 is fixedly installed on the bottom end of the driving shaft 23, and an active bevel gear 25 is rotatably installed on the bottom end of the bracket 22, and the active bevel gear 25 is meshed with the concave tooth portion 21 and the driven bevel gear 24 at the same time; A driving gear 26 is installed at the end of the driving shaft 23 . The driving gear 26 is meshed with a driven gear 27 installed on the longitudinal shaft 28 . The thickness of the driving gear 26 is greater than that of the driven gear 27 .

[0024] In one embodiment of the present invention, when the movable block 20 slides along the positioning cross bar 15, since the concave tooth portion 21 is in a meshing state with the active bevel gear 25, the active bevel gear 25 can be rotated along the bottom end of the bracket 22 during the movement of the movable block 20, and the drive shaft 23 is driven to rotate along the top end of the bracket 22 through the set driven bevel gear 24, and the drive gear 26 rotates synchronously with the drive shaft 23. Since the drive gear 26 and the driven gear 27 are always in a meshing state, the rotation stability can be maintained when the longitudinal axis 28 floats along the movable block 20, so that the grinding head 29 can rotate smoothly in a floating state, thereby completing the polishing and deburring work of the inner wall of the pipe fitting 3.

[0025] In summary, the actual use is based on the instructions attached Figure 1As a reference, the pull ring 12 is pulled outward, and the pull ring 12 drives the guide rod 9 and the clamping head 10 to slide along the sleeve 8 through the set pull rope 11, pushing the pipe 3 from the left to the right, and the clamping block 5 is forced to push the guide column 4 to slide along the fixing frame 2, and the elastic support member 7 is elastically deformed under the force, and after the pipe 3 moves to the specified position, the clamping work on the outer side of the pipe 3 is realized through the clamping block 5 under the action of the elastic support member 7. After the installation of the pipe 3 is completed , loosen the pull ring 12, the guide rod 9 moves outward in the opposite direction under the action of the built-in micro elasticity, and the fixing work on the inner side of the pipe 3 is completed by using the arranged tightening head 10. The pipe 3 drives the fixing frame 2 and the pipe 3 to rotate synchronously under the drive of the external motor. At the same time, the rotating motor 19 can drive the driving screw 16 on one side to rotate along the side plate 14 through the coupling. The driving screw 16 also drives the driving screw 16 on the other side to rotate synchronously through the arranged pulley 17 and the synchronous belt 18. The driving screw 16 works synchronously to push the movable block 20 at the corresponding position to slide along the positioning cross bar 15. When the movable block 20 slides along the positioning cross bar 15, since the concave tooth portion 21 is in meshing state with the active bevel gear 25, the active bevel gear 25 can be rotated along the bottom end of the bracket 22 during the movement of the movable block 20, and the driving shaft 23 is driven to rotate along the top end of the bracket 22 through the set driven bevel gear 24. The driving gear 26 rotates synchronously with the driving shaft 23, and since the driving gear 26 and the driven gear 27 are always in meshing state, the grinding heads 29 set on both sides can realize the deburring work on the inner and outer sides of the pipe fitting 3 when the longitudinal axis 28 floats along the movable block 20; the deburring device is convenient for clamping, and has high stability during the deburring process. The grinding depth can be automatically adjusted during deburring, and the inner and outer surfaces of the regular and irregular pipe fittings 3 can be automatically adapted during grinding and polishing to deburr, so as to improve the grinding efficiency while ensuring that the grinding quality of the uneven surface is consistent.
