DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0028] Embodiment 1:

[0029] See also Figure 1-10 , the present invention provides a technical solution:

[0030] The invention discloses a high-efficiency metal pipe groove processing machine, comprising a processing table 1, a power shaft 2, a support shaft 3 and a grinding knife 4, wherein the support shaft 3 and the power shaft 2 are rotatably connected, and further comprising an extension rod 5, wherein the extension rod 5 is located on the power shaft 2, and the distance between the grinding knife 4 and the power shaft 2 is controlled by the extension rod 5.

[0031] The grinding assembly 6 is arranged on the power shaft 2, and the extension rod 5 is arranged on the grinding assembly 6. The grinding assembly 6 synchronously drives the extension rod 5 to adjust the distance between the grinding knife 4 and the power shaft 2 according to the movement trajectory of the grinding knife 4 on the square tube.

[0032] The advantage of the grinding assembly 6 is that it can process square pipes of different specifications and sizes without replacing or adjusting equipment, thereby improving production efficiency, while also increasing the flexibility of the processing process, reducing the time for changing equipment, and improving the flexibility of the production line.

[0033] The adjusting mechanism 11 is arranged on the grinding assembly 6. The adjusting mechanism 11 adjusts the motion trajectory of the grinding assembly 6 when driving the grinding knife 4 to move, so that the grinding assembly 6 switches from square tube beveling processing to circular tube beveling processing.

[0034] The advantage of setting up the adjustment mechanism 11 is that it can change the moving trajectory of the grinding knife 4. After the staff completes the beveling processing of the square pipe, when beveling the circular pipe, there is no need to replace the new beveling processing equipment. Only simple adjustments are needed to make the equipment adapt to circular pipes with different diameters. The same equipment can complete the processing of pipes of various shapes and specifications, which can effectively improve production efficiency and processing speed. Furthermore, this beveling processing equipment can be used for processing pipes of different shapes, which improves its flexibility and versatility in use. At the same time, one beveling processing machine can process pipes of various specifications and sizes without purchasing multiple processing machines, which can save equipment costs and space.

[0035] The grinding assembly 6 includes a mounting member 7 arranged on the power shaft 2, and the grinding knife 4 is installed and fixed by the mounting member 7. The mounting member 7 is provided with a driving member 8, and the driving member 8 provides power for the displacement of the extension rod 5. The driving member 8 is provided with a connecting member 9, and the grinding knife 4 is connected to the extension rod 5 by the connecting member 9. The mounting member 7 is provided with a stabilizing member 10, and the stabilizing member 10 is used to control the grinding knife 4 to always be perpendicular to the grinding surface of the pipeline during the movement.

[0036] The mounting member 7 includes a mounting plate 71 arranged on the power shaft 2, the mounting plate 71 is rotatably connected to the support shaft 3, a sliding groove 72 is opened on the mounting plate 71, a sliding block 73 is slidably arranged in the sliding groove 72, a rotating shaft 74 is rotatably arranged on the sliding block 73, the rotating shaft 74 passes through the sliding block 73, and a torsion spring 75 is sleeved on a section of the rotating shaft 74 located in the sliding block 73. The torsion spring 75 is respectively connected to the sliding block 73 and the rotating shaft 74, and one end of the rotating shaft 74 is connected to the grinding knife 4.

[0037] The advantage of the mounting member 7 is that it can improve the stability of the grinding knife 4 when grinding square pipes. The grinding knife 4 is controlled by the torsion spring 75 to always be perpendicular to the grinding surface of the pipe during operation, making the grinding knife 4 more stable and improving the quality of pipe slope processing.

[0038] The driving member 8 includes a driving ring gear 81 installed on the supporting shaft 3, a driving shaft 82 is rotatably provided on the mounting plate 71, a driving gear 83 engaged with the driving ring gear 81 is provided on the driving shaft 82, a pushing rod 84 is provided on the driving shaft 82, a pushing shaft 85 is provided on the end of the pushing rod 84 away from the driving shaft 82, a plurality of guide plates 86 are provided on the mounting plate 71, a sliding plate 87 is slidably provided on the guide plate 86, a pushing plate 88 is provided on the end of the sliding plate 87 close to the pushing shaft 85, a pushing groove 89 is opened on the pushing plate 88, and the pushing shaft 85 passes through the pushing groove 89 and is movably connected with the pushing groove 89.

[0039] The connecting member 9 includes an extension groove 91 opened on the sliding plate 87, and the extension groove 91 is slidably connected to the extension rod 5. The extension rod 5 is provided with a fixing plate 92, and the grinding knife 4 is provided with a connecting plate 93. The connecting plate 93 is provided with a connecting shaft 94, and the connecting shaft 94 is rotatably connected to the fixing plate 92.

[0040] The advantage of the connection member 9 is that it does not affect the angle of the grinding knife 4 during the movement, so that the grinding work of the grinding knife 4 is more stable.

[0041] When the power shaft 2 rotates, it drives the mounting plate 71 disposed on the power shaft 2 to rotate synchronously. When the mounting plate 71 rotates, it drives the driving gear 83 to move around the driving ring gear 81 through the driving shaft 82. When the driving gear 83 moves, it rotates under the push of the driving ring gear 81 that meshes with it. The driving gear 83 rotates, driving the driving shaft 82 to rotate synchronously. When the driving shaft 82 rotates, it drives the pushing rod 84 and the pushing shaft 85 disposed on the driving shaft 82 to rotate synchronously. When the pushing shaft 85 rotates, it moves in the pushing groove 89, thereby driving the pushing plate 88 and the sliding plate 87 to slide on the guide plate 86. When the sliding plate 87 moves, it drives the extension rod 5 disposed thereon to move. When the extension rod 5 moves, it drives the fixed plate 92 to move, and synchronously drives the grinding knife 4 to move through the connecting plate 93 and the connecting shaft 94 to perform groove processing on the pipeline.

[0042] The stabilizing member 10 includes a rotating gear 101 disposed on the rotating shaft 74, mounting grooves 102 are provided on both sides of the mounting plate 71, a plurality of movable plates 103 are slidably disposed in the mounting grooves 102, the movable plates 103 are L-shaped plates, a rack 104 used in conjunction with the rotating gear 101 is disposed on the movable plate 103, a plurality of synchronous plates 105 are disposed on the movable plates 103, the synchronous plates 105 penetrate the mounting plate 71 and are slidably connected to the mounting plate 71, the A pushing airbag 106 is arranged in the mounting groove 102, and extrusion airbags 108 are arranged at both ends of the sliding groove 72. An air guide tube 107 is arranged on the extrusion airbag 108. The air guide tube 107 passes through the mounting plate 71 and enters the mounting groove 102 and is connected with the pushing airbag 106. A plurality of positioning plates 109 are arranged on both sides of the mounting plate 71. The positioning plates 109 are L-shaped plates. Fixed magnetic sheets 1010 that attract each other are arranged on the positioning plates 109 and the movable plate 103.

[0043] The advantage of the stabilizing member 10 is that it can adjust the angle between the grinding knife 4 and the extension rod 5 according to the position of the grinding knife 4 on the square pipe, so that the grinding knife 4 is always perpendicular to the grinding surface of the pipe. At the same time, the grinding knife 4 cannot rotate freely by locking the rack 104 and the rotating gear 101, thereby further improving the stability of the grinding knife 4 during grinding.

[0044] When the grinding knife 4 moves, it drives the rotating shaft 74 and the sliding block 73 connected to the rotating shaft 74 to move in the sliding groove 72. When the rotating shaft 74 moves, it drives the rotating gear 101 to move. When the rotating gear 101 moves, it rotates under the push of the rack 104, driving the drive shaft 82 and the grinding knife 4 to rotate, so that the grinding knife 4 always remains perpendicular to the grinding surface during the movement. When the grinding knife 4 starts to grind from the corner of the square pipe, at this time, the grinding knife 4 forms an angle with the extension rod 5 under the push of the torsion spring 75 in the initial state, and is perpendicular to the grinding surface of the pipe. Then the grinding knife 4 moves on the grinding surface and always remains perpendicular to the grinding surface under the control of the rotating gear 101. At the same time, the torsion spring 75 is tightened under the control of the rotating gear 101. When the grinding knife 4 moves to the side of the pipe When the grinding knife 4 reaches the midpoint of the sliding groove 72, the sliding block 73 drives the grinding knife 4 to move to the bottom of the sliding groove 72, and at the same time compresses and squeezes the airbag 108, so that the pushing airbag 106 expands, and further pushes the rack 104 that is engaged with the rotating gear 101 during the descent of the grinding knife 4 to disengage from the rotating gear 101. At the same time, when the rack 104 on one side disengages and is connected to the fixed magnetic sheet 1010 provided on the positioning plate 109, the rack 104 on the other side is driven by the synchronization plate 105 to re-engage with the rotating gear 101, so that the angle direction between the grinding knife 4 and the extension rod 5 remains unchanged during the ascending process. When the grinding knife 4 rises to the top, the rotating gear 101 is disengaged from the rack 104. At this time, the grinding knife 4 is reset under the drive of the torsion spring 75, and grinds the other side of the square pipe.

[0045] The adjustment mechanism 11 includes an adjustment member 12 arranged on the sliding plate 87, through which the position of the grinding knife 4 is adjusted according to the diameter of the circular pipe. A disengagement member 13 is provided on the support shaft 3, and the disengagement member 13 is used to control the drive ring gear 81 to be disconnected from the support shaft 3 when performing the circular pipe beveling operation.

[0046] The adjusting member 12 includes an extruded screw rod 121 disposed on the sliding plate 87 . One end of the extruded screw rod 121 extends into the extension groove 91 and is threadedly connected to the sliding plate 87 . A rotating knob 122 is disposed at one end of the extruded screw rod 121 .

[0047] The advantage of setting the adjustment member 12 is that it can quickly adjust the extension length of the extension rod 5 according to the shape and size of the pipe, so that this groove processing equipment can adapt to pipes of various shapes and sizes. The extension rod 5 is squeezed and fixed by rotating the extrusion screw 121 to achieve the effect of adjusting the extension length of the extension rod 5. While adjusting the length of the extension rod 5, the staff will simultaneously add additional components to the sliding block 73 according to the actual adjustment length, so that the sliding block 73 can still compress the extrusion airbag 108 during the descent process. This is a prior art, so it will not be elaborated here.

[0048] The disengagement member 13 includes a clamping plate 131 arranged on the support shaft 3, and a clamping groove 132 is opened on the clamping plate 131. A clamping block 133 used in conjunction with the clamping groove 132 is arranged on the inner side of the driving gear ring 81, and the clamping block 133 is interference fit with the clamping groove 132. A connecting magnetic sheet 134 that attracts each other is arranged on one side of the driving gear ring 81 close to the mounting plate 71 and on the mounting plate 71.

[0049] The advantage of setting up the disengagement member 13 is that it can make the driving ring gear 81 disengage from the connection with the support shaft 3, so that the driving ring gear 81 can rotate with the mounting plate 71, thereby making the position of the grinding knife 4 unchanged, making it convenient for the staff to perform beveling operations on the circular pipe. When in use, it is only necessary to push the driving ring gear 81 to disengage the clamping block 133 from the clamping groove 132, and the driving ring gear 81 will be adsorbed on the mounting plate 71 under the action of the connecting magnetic sheet 134.

[0050] When in use, the staff first adjusts the length of the extension rod 5 and the connection position of the driving gear ring 81 according to the shape and size of the pipeline, and then drives the power shaft 2 to rotate through external power, and at the same time drives the mounting plate 71 set on the power shaft 2 to rotate synchronously. When the mounting plate 71 rotates, the driving gear 83 is driven to move around the driving gear ring 81 through the driving shaft 82. When the driving gear 83 moves, it rotates under the push of the driving gear ring 81 engaged with it. The driving gear 83 rotates, driving the driving shaft 82 to rotate synchronously. When the driving shaft 82 rotates, it drives the push rod 84 and the push shaft 85 set on the driving shaft 82 to rotate synchronously. When the push shaft 85 rotates, it moves in the push groove 89, thereby driving the push plate 88 and the sliding plate 87 to slide on the guide plate 86. When the sliding plate 87 moves, it drives the extension rod 5 set thereon to move. When the extension rod 5 moves, it drives the fixed plate 92 to move, and synchronously drives the grinding knife 4 to move through the connecting plate 93 and the connecting shaft 94 to perform groove processing on the pipeline.

[0051] When the grinding knife 4 moves, it drives the rotating shaft 74 and the sliding block 73 connected to the rotating shaft 74 to move in the sliding groove 72. When the rotating shaft 74 moves, it drives the rotating gear 101 to move. When the rotating gear 101 moves, it rotates under the push of the rack 104, driving the drive shaft 82 and the grinding knife 4 to rotate, so that the grinding knife 4 always remains perpendicular to the grinding surface during the movement. When the grinding knife 4 starts to grind from the corner of the square pipe, at this time, the grinding knife 4 forms an angle with the extension rod 5 under the push of the torsion spring 75 in the initial state, and is perpendicular to the grinding surface of the pipe. Then the grinding knife 4 moves on the grinding surface and always remains perpendicular to the grinding surface under the control of the rotating gear 101. At the same time, the torsion spring 75 is tightened under the control of the rotating gear 101. When the grinding knife 4 moves to the side of the pipe When the grinding knife 4 reaches the midpoint of the sliding groove 72, the sliding block 73 drives the grinding knife 4 to move to the bottom of the sliding groove 72, and at the same time compresses and squeezes the airbag 108, so that the pushing airbag 106 expands, and further pushes the rack 104 that is engaged with the rotating gear 101 during the descent of the grinding knife 4 to disengage from the rotating gear 101. At the same time, when the rack 104 on one side disengages and is connected to the fixed magnetic sheet 1010 provided on the positioning plate 109, the rack 104 on the other side is driven by the synchronization plate 105 to re-engage with the rotating gear 101, so that the angle direction between the grinding knife 4 and the extension rod 5 remains unchanged during the ascending process. When the grinding knife 4 rises to the top, the rotating gear 101 is disengaged from the rack 104. At this time, the grinding knife 4 is reset under the drive of the torsion spring 75, and grinds the other side of the square pipe.
