Description

Technical Field

[0002] A plasma cutting gun is a device that generates a high-temperature plasma arc to melt the cut of the workpiece to be cut. Due to its high cutting efficiency and smooth cut, it is widely used in high-hardness workpieces to be cut. In actual use, the operator is usually required to hold the handle of the plasma cutting machine and aim the nozzle of the cutting gun at the workpiece to be cut to complete the cutting work. The problem with this operation method is that the cutting work time is long, and the plasma cutting machine is heavy, so it is difficult for the operator to hold the plasma cutting machine for a long time to perform the cutting work. In addition, the distance and angle from the nozzle of the cutting gun to the workpiece to be cut are difficult to accurately control, and cutting errors are prone to occur, thereby affecting the accuracy of the workpiece to be cut. In addition, when the workpiece to be cut is fixed and transported, it is difficult to effectively fix the workpieces to be cut of different specifications. For the workpiece to be cut with a complex structure, it is impossible to rotate the angle after fixing, making it difficult for the cutting gun to cut the bottom, affecting the cutting efficiency and cutting accuracy.

[0015] In this embodiment, the lifting and moving device 2 includes: Two lifting columns 21 are symmetrically arranged and fixed on the front and rear sides of the positioning platform 1; A fixed horizontal column 22, with both ends fixed to the tops of the lifting columns 21 on both sides; Two longitudinal sliding rails 23 are provided in the upper and lower parts and fixed on one side of the fixed horizontal column 22, and the two ends of the longitudinal sliding rails 23 correspond to the lifting columns 21 on both sides respectively; The moving member 24 is movably arranged on the fixed horizontal column 22 and connected to the longitudinal sliding track 23 , and the bottom of the moving member 24 is fixedly connected to the cutting auxiliary device 6 .

[0016] That is to say, after the clamping auxiliary device 5 clamps and fixes the workpiece to be cut, the lifting column 21 drives the cutting auxiliary device 6 to move up and down according to the height of the workpiece to be cut, and adjusts the distance between the cutting auxiliary device 6 and the workpiece to be cut to facilitate precise cutting of the workpiece to be cut. Under the action of the longitudinal sliding track 23, the moving part 24 drives the cutting auxiliary device 6 to move longitudinally on the fixed horizontal column 22 to perform mobile cutting on the workpiece to be cut.

[0017] In this embodiment, the moving component 3 includes: Two transverse sliding rails 31 are symmetrically arranged front and rear, and are fixed on the positioning platform 1 respectively; The fixed racks 32 are provided with two symmetrically distributed front and rear and are respectively fixed on the inner side of the positioning platform 1; The movable slider 33 is arranged corresponding to the horizontal sliding track 31 and is slidably arranged on the horizontal sliding track 31; The two ends of the bottom of the bearing panel 34 are respectively fixed on the movable sliders 33 on both sides, and a control mechanism is provided inside the bearing panel 34; Two transmission gears 35 are symmetrically arranged and rotatably arranged at the bottom of the bearing panel 34 , and the transmission gears 35 are meshed with the corresponding fixed racks 32 .

[0018] That is to say, under the action of the control mechanism inside the carrying panel 34, the transmission gear 35 is controlled to rotate, and then under the restriction of the fixed rack 32, the transmission gear 35 drives the carrying panel 34 to move on the horizontal sliding track 31 through the moving slider 33, and then drives the workpiece to be cut to move and locate the cutting position, so that the cutting auxiliary device 6 can cut the workpiece.

[0019] In this embodiment, the rotating device 4 includes: The limiting arc plates 41 are provided with two pieces symmetrically distributed front and back and fixed at the two ends of the bearing panel 34 respectively; A rotating gear ring 42 is rotatably disposed between the limiting arc plates 41, and the bottom of the rotating gear ring 42 is rotatably connected to the bearing panel 34; Two active telescopic positioning shafts 43 are symmetrically arranged in the upper and lower parts and are respectively fixed on the inner wall of the rotating gear ring 42, and the active telescopic positioning shafts 43 are fixedly connected to the clamping auxiliary device 5; The passive telescopic positioning shafts 44 are symmetrically distributed in two groups, each group is symmetrically distributed with two active telescopic positioning shafts 43 , and are respectively fixed on the inner wall of the rotating gear ring 42 , and the passive telescopic positioning shafts 44 are slidably connected to the clamping auxiliary device 5 .

[0020] That is to say, the clamping auxiliary device 5 is driven by the active telescopic positioning shaft 43 to fix the workpiece to be cut, and multiple passive telescopic positioning shafts 44 are used for auxiliary fixation to maintain the stability of the workpiece to be cut in the clamping auxiliary device 5, and then under the action of the internal control mechanism of the load-bearing panel 34, the rotating gear ring 42 is driven to rotate between the load-bearing panel 34 and the limiting arc plate 41, and then the workpiece to be cut is driven to rotate by the clamping auxiliary device 5, so as to facilitate the all-round cutting of the workpiece by the cutting auxiliary device 6, and under the dual control of the clamping auxiliary device 5 and the cutting auxiliary device 6, the distance and angle from the nozzle of the cutting gun to the workpiece to be cut are accurately positioned, which effectively reduces the cutting error and helps to improve the accuracy of the workpiece to be cut.

[0021] In this embodiment, the clamping auxiliary device 5 includes: The connecting arc surfaces 51 are symmetrically arranged in two upper and lower parts, and are arranged in the rotating device 4, and the upper and lower connecting arc surfaces 51 are two parts of the same ring body; The adjusting arc surfaces 52 are symmetrically arranged in two parts, and are respectively fixed on the inner sides of the corresponding connecting arc surfaces 51, and the upper and lower adjusting arc surfaces 52 are two parts of the same annular surface; The fixed adjustment components 53 are symmetrically arranged in two groups, each group is symmetrically arranged with two components, and are movably arranged on the adjustment arc surface 52; The clamping assembly 54 is arranged corresponding to the fixed adjustment assembly 53 and is rotatably arranged on the fixed adjustment assembly 53 .

[0022] That is to say, when the specification of the workpiece to be cut can be completely placed between the two adjustment arc surfaces 52, at this time, the upper and lower two active telescopic positioning shafts 43 drive the connecting arc surfaces 51 to fit each other, and then the adjustment arc surfaces 52 are combined into a ring surface, and the workpiece to be cut is located between the ring surfaces, and then the fixed adjustment component 53 is fixed on the adjustment arc surface 52, and the workpiece to be cut is fixed at the center position of the ring surface formed by the adjustment arc surface 52 through the clamping component 54, and also at the center of the rotating gear ring 42; when the specification of the workpiece to be cut is larger than the ring surface formed by the two adjustment arc surfaces 52, at this time, the upper and lower two active telescopic positioning shafts 43 drive The connecting arc surface 51 moves toward the upper and lower sides of the workpiece to be cut, and at the same time, the fixed adjustment component 53 is fixed on the adjustment arc surface 52, and the clamping component 54 is rotated so that the clamping component 54 fits the surface of the workpiece to be cut. Under the continuous pressure of the active telescopic positioning shaft 43, the clamping component 54 fixes the workpiece to be cut. At this time, the center of the workpiece to be cut is still at the center of the rotating gear ring 42, that is, when the rotating gear ring 42 drives the clamping auxiliary device 5 to rotate, the workpiece to be cut rotates with its own center as the center of the circle, effectively avoiding the workpiece to be cut from being offset during the rotation process and conflicting with the position of the cutting auxiliary device 6.

[0023] In this embodiment, the fixed adjustment component 53 includes: The fixing plate 531 is in a right angle shape and is slidably disposed on the inner ring and the side of the adjusting arc surface 52; The positioning plate 532 is composed of a bottom plate and a vertical plate perpendicular to the middle of the bottom plate, the vertical plate is slidably connected to the fixing plate 531, and one end of the bottom plate is slidably arranged in the gap between the adjusting arc surface 52 and the connecting arc surface 51; The adjustment platform 533 is disposed on the side of the adjustment arc surface 52 and is fixedly connected to the fixing plate 531; The adjusting screw 534 is rotatably connected to the bottom plate in the positioning plate 532 and is threadedly connected to the adjusting platform 533 .

[0024] That is to say, under the action of the fixing plate 531 and the positioning plate 532, the fixed adjustment component 53 is stuck on the adjustment arc surface 52, and the adjustment screw 534 is moved toward the inside of the adjustment platform 533 by rotating the adjustment screw 534, and the positioning plate 532 is simultaneously driven to move toward the position of the fixing plate 531, and then the fixed adjustment component 53 is fixed on the adjustment arc surface 52 through the fixing plate 531 and the positioning plate 532.

[0025] In this embodiment, the clamping assembly 54 includes: A rotating shaft 541 is rotatably disposed on the adjustment platform 533, and the rotating shaft 541 is perpendicular to the side of the adjustment arc surface 52; The adjusting connecting member 542 is rotatably disposed on the adjusting platform 533 and is fixedly connected to the rotating shaft 541; The clamping roller 543 is rotatably disposed on the adjusting connecting member 542 and corresponds to the workpiece to be cut.

[0026] That is to say, when the fixed adjustment component 53 is fixed on the adjustment arc surface 52, the adjustment connecting member 542 can be driven to rotate by rotating the rotating shaft 541, thereby driving the clamping roller 543 to fit the surface of the workpiece to be cut. Under the joint action of multiple clamping rollers 543, the workpiece to be cut is fixed.

[0027] In this embodiment, the cutting auxiliary device 6 includes: The first adjustment component 61 is fixed on the lifting and moving device 2; The limiting arc 62 is semicircular and is disposed at the bottom center of the first adjusting component 61, and the first adjusting component 61 is slidably connected to the limiting arc 62; The adjusting arcs 63 are symmetrically provided with two of them, fixed on both sides of the limiting arc 62, and the first adjusting component 61 is connected to the side of the adjusting arc 63; A second adjustment component 64 is arranged outside the one side adjustment arc 63; Two movable positioning components 65 are symmetrically arranged front and back and are respectively movably arranged at the two ends of the bottom of the limiting arc 62 and the adjusting arc 63; The cutting gun regulating assembly 66 is movably arranged on the second regulating assembly 64 .

[0028] That is to say, driven by the first adjusting component 61 and limited by the limiting arc 62, the adjusting arc 63 moves on the first adjusting component 61, thereby driving the cutting gun regulating component 66 to move along the trajectory of the regulating arc 63. At the same time, under the action of the second adjusting component 64, the cutting gun regulating component 66 is driven to extend again along the moving trajectory of the regulating arc 63, so as to facilitate multi-angle cutting of the workpiece to be cut, mainly for cutting the workpiece to be cut that is inconvenient to rotate, such as the workpiece that cannot be rotated due to length limitation. When cutting a workpiece with a specification smaller than the radius of the limiting arc 62, the adjusting arc 63 and the second adjusting component 64 can be used to cut the workpiece in all directions, or the workpiece to be cut can be driven to rotate by the rotating device 4 for fixed-point cutting; when cutting a workpiece with a specification larger than the radius of the limiting arc 62, the surface of the workpiece can be supported and positioned by the moving positioning component 65, or the two adjacent surfaces can be clamped and positioned, so that the cutting gun regulating component 66 can gradually cut the workpiece to be cut.

[0029] In this embodiment, the first adjustment component 61 includes: The limiting shaft 611 is fixed at the bottom center of the moving member 24; The limiting arc surface 612 is fixed at the bottom of the limiting shaft 611, and the limiting arc surface 612 is slidably arranged in the limiting arc path 62; Two connecting plates 613 are symmetrically arranged about the limiting axis 611 and are respectively arranged on the outside of the adjusting arc 63 on both sides, and the connecting plates 613 are fixed to the bottom of the moving member 24; The adjusting roller 614 is disposed corresponding to the connecting plate 613 , and is rotatably disposed at the lower portion of the connecting plate 613 . The adjusting roller 614 is rollingly connected to the adjusting arc 63 .

[0030] That is to say, under the rotation of the adjusting roller 614, the adjusting arc 63 drives the limiting arc 62 to rotate synchronously, and then the limiting arc 62 slides on the limiting arc surface 612, and the position of the cutting gun regulating assembly 66 is adjusted by adjusting the arc 63. Under the restriction of the limiting arc 62, the adjustment range of the cutting gun regulating assembly 66 is the moving range of the adjusting roller 614 on the adjusting arc 63.

[0031] In this embodiment, the second adjustment component 64 includes: The arc-shaped tooth track 641 is rotatably arranged on the outer side of the side adjustment arc track 63; Two regulating gears 642 are symmetrically arranged and mesh with both ends of the arc-shaped tooth track 641; The driving motor 643 is provided corresponding to the regulating gear 642 , fixed at two ends of the lower part of the regulating arc 63 , and the driving motor 643 is connected to the regulating gear 642 .

[0032] That is to say, driven by the driving motor 643, the arc-shaped tooth track 641 is driven to rotate on the adjusting arc track 63 through the adjusting gear 642, thereby driving the cutting gun adjusting component 66 to follow the arc-shaped tooth track 641 for movement and adjustment, and the cutting gun adjusting component 66 can be movably set on the arc-shaped tooth track 641, that is, the cutting gun adjusting component 66 can slide on the adjusting arc track 63, the arc-shaped tooth track 641 and on the arc-shaped tooth track 641 for multi-level adjustment, so as to adapt to different specifications of workpieces to be cut and perform precise cutting.

[0033] In this embodiment, the mobile positioning component 65 includes: A movable panel 651 is slidably disposed at one end of the bottom of the limiting arc path 62 and the adjusting arc path 63; The positioning arc surface 652 is fixed on one side of the movable panel 651 close to the center of the limiting arc 62; A plurality of positioning rollers 653 are linearly distributed and arranged parallel to the positioning arc surface 652 , and the positioning rollers 653 are rollingly arranged at the bottom of the movable panel 651 ; The moving mechanism 654 is arranged at the connection between the top of the moving panel 651 and the limiting arc 62; The limiting mechanism 655 is arranged at the connection between the top of the movable panel 651 and the adjusting arc path 63 .

[0034] That is to say, when the cutting auxiliary device 6 cuts a single plane of the workpiece to be cut, the positioning rollers 653 of the movable positioning components 65 on both sides can fit with the surface of the workpiece, and then when the cutting auxiliary device 6 is driven by the moving part 24 to move and cut, the positioning rollers 653 can roll on the surface of the workpiece to be cut to assist in positioning; when the cutting auxiliary device 6 cuts at the angle of the workpiece to be cut, the moving panel 651 can be driven to move by the moving mechanism 654, and then under the restriction of the limiting mechanism 655, the moving panel 651 drives the positioning arc surface 652 to fit with the two adjacent side surfaces of the workpiece, and positions the position between the workpiece to be cut and the cutting gun regulating component 66, so that the cutting gun regulating component 66 can accurately cut the workpiece to be cut.

[0035] During specific implementation, the cutting auxiliary device 6 is first driven upward by the lifting and moving device 2 to avoid conflict with the position of the cutting auxiliary device 6 when fixing the workpiece, thereby avoiding damage to the cutting auxiliary device 6 or the workpiece to be cut. The workpiece to be cut is then passed through the center of the clamping auxiliary device 5, and then the clamping component 54 is fixed on the adjusting arc surface 52 by the fixing adjustment component 53. Then, under the action of the active telescopic positioning shafts 43 on the upper and lower sides, the connecting arc surface 51 is driven to move toward the center of the workpiece to be cut. Under the drive of the adjusting arc surface 52, the clamping component 54 is driven to move toward the surface of the workpiece to be cut. At the same time, the adjusting connecting piece 542 is driven to rotate through the rotating shaft body 541, thereby driving the clamping roller 543 to fit with the surface of the workpiece to be cut. Under the joint action of multiple clamping rollers 543, the workpiece to be cut is The workpiece to be cut is fixed, and then under the action of the moving components 3 on both sides, the workpiece to be cut is driven to move on the positioning platform 1, and the point to be cut is aligned with the position of the cutting gun. Then the lifting and moving device 2 drives the cutting auxiliary device 6 to move down to cut the workpiece to be cut. When cutting a workpiece with a specification smaller than the radius of the limiting arc 62, the arc 63 and the second adjusting component 64 can be used to drive the cutting gun regulating component 66 to perform all-round cutting of the workpiece, and the rotating device 4 can also be used to drive the workpiece to be cut to rotate for fixed-point cutting; when cutting a workpiece with a specification larger than the radius of the limiting arc 62, the surface of the workpiece can be supported and positioned by the moving positioning component 65, or the two adjacent surfaces can be clamped and positioned, so that the cutting gun regulating component 66 can gradually cut the workpiece to be cut.

[0036] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto.
