[0037] Figure 1 and Figure 2 , is a schematic structural diagram of a clamping mechanism 10 in one embodiment.

[0038] In this embodiment, the clamping mechanism 10 can be applied to a round pipe welding device, such as Figure 1 and Figure 2 As shown, the clamping mechanism 10 includes a clamp bearing seat 120 and a front pressing clamp 140 .

[0039] The fixture bearing seat 120 can bear the plate to be processed.

[0040] The fixture bearing seat 120 can be arranged opposite to the front pressure fixture 140, and can receive the plate to be processed transported by the auxiliary support mechanism 20 in the round tube welding device, and has a functional structure for constraining the position of the plate to be processed.

[0041] The front pressing clamp 140 is arranged opposite to the clamp supporting seat 120, and the front pressing clamp 140 includes a first pressing member 1420 and a second pressing member 1440. The first pressing member 1420 can abut against the first end face of the plate to be processed, and the second pressing member 1440 can abut against the second end face of the plate to be processed. The first end face and the second end face are arranged relative to the plate to be processed.

[0042] The front pressing fixture 140 may be a functional structure that is arranged opposite to the fixture bearing seat 120 and can exert a holding action on the first end face and the second end face of the plate to be processed to drive the two ends of the plate to be processed to bend. The first pressing member 1420 may be a position adjustment functional member that can abut against the first end face of the plate to be processed and drive one end of the plate to be processed to bend toward the middle of the plate under the holding action. The second pressing member 1440 may be a position adjustment functional member that can abut against the second end face of the plate to be processed and drive the other end of the plate to be processed to bend toward the middle of the plate under the holding action.

[0043] It should be noted that when clamping the plate to be processed, the first clamping member 1420 and the second clamping member 1440 usually apply a supporting effect to both ends of the plate to be processed at the same time. The dispersed stress in the middle of the plate can be offset due to the supporting effect at both ends, so as to synchronously drive the two ends of the plate to be processed to bend toward the middle of the plate and tend to align, thereby ensuring the clamping stability of the plate to be processed and improving the bending processing efficiency of the plate to be processed.

[0044] Alternatively, if Figure 3 As shown, the fixture bearing seat 120 includes a positioning member 1220 and a support frame 1240. The positioning member 1220 is disposed on the support frame 1240. The positioning member 1220 can abut against the first end surface or the second end surface of the plate to be processed.

[0045] The positioning member 1220 may be a positioning functional member disposed on the support frame 1240 and capable of constraining the position of the plate to be processed before the first pressing member 1420 and the second pressing member 1440 exert a holding action on both ends of the plate to be processed. Optionally, the positioning member 1220 may be a positioning pin. The support frame 1240 may be a supporting structure having a supporting end surface disposed in the vertical direction and a supporting base disposed in the horizontal direction, and capable of providing a plurality of positioning members 1220 distributed at intervals on the back of the supporting end surface in the vertical direction.

[0046] A strip-shaped through hole is opened along the geometric center line of the support end surface in the vertical direction, and the ratio of the length of the strip-shaped through hole to the height of the support end surface in the vertical direction is greater than M.

[0047] The strip-shaped through hole may be opened along the geometric center line of the vertical direction of the support end surface, and may allow the back protection component 1260 to be embedded in the strip-shaped through hole in the support end surface. The value range of M may be: 0<M<1.

[0048] Alternatively, if Figure 4 As shown, the fixture bearing seat 120 also includes a back protection component 1260, which is disposed on the support frame 1240. The back protection component 1260 is provided with a plurality of ventilation holes, and the plurality of ventilation holes are spaced apart in the vertical direction.

[0049] The back protection component 1260 can be embedded in the supporting end surface of the fixture support seat 120 in the vertical direction, and a vent hole is opened in the back cavity. The protective gas is connected through the vent hole to introduce the protective gas during the processing to prevent the processing position from being oxidized.

[0050] It should be noted that in the actual processing process, multiple vent holes are usually arranged at equal intervals in the vertical direction on the back cavity of the back protection component 1260, which can ensure the uniformity and smoothness of the introduction of protective gas when the vent holes need to be connected to the protective gas, thereby improving the anti-oxidation effect of the processing position.

[0051] Alternatively, if Figure 5 As shown, the front pressure clamp 140 also includes a mounting frame 1460, a first clamping member 1420 and a second clamping member 1440 are arranged on the mounting frame 1460, the mounting frame 1460 and the support frame 1240 have the same height in the vertical direction, and the side of the mounting frame 1460 is connected to the side of the support frame 1240. By connecting the mounting frame 1460 and the side of the support frame 1240 set at the same height, the coordination stability and feasibility of the two can be guaranteed, thereby improving the assembly stability of the clamp bearing seat 120 and the front pressure clamp 140.

[0052] The mounting frame 1460 may be a support structure having a mounting end surface arranged in the vertical direction, a mounting base arranged in the horizontal direction, and a first pressing member 1420 and a second pressing member 1440 arranged at intervals on the back of the mounting end surface in the vertical direction. The side surface of the mounting frame 1460 and the side surface of the support frame 1240 are fixed in position by a plurality of fixing members.

[0053] The mounting frame 1460 is provided with a mounting end surface along the vertical direction, and the supporting frame 1240 is provided with a supporting end surface along the vertical direction, and the mounting end surface and the supporting end surface are arranged opposite to each other and in parallel.

[0054] The clamping mechanism 10 provided in the present embodiment, when clamping the plate to be processed, the clamp bearing seat 120 bears the plate to be processed, and the front pressure clamp 140 arranged opposite to the clamp bearing seat 120 abuts against the relatively arranged first end face and second end face of the plate to be processed through the first clamping member 1420 and the second clamping member 1440, and can apply a holding force to both ends of the plate to be processed, so as to adjust the position of the two ends of the plate to be processed, thereby driving the plate to be processed to bend and the two ends to be aligned, thereby ensuring the clamping and pressing accuracy of the plate to be processed, effectively improving the consistency of the round tube welding quality, and thus meeting the batch production and processing needs of the workshop.

[0055] Figure 6 , is a schematic diagram of the specific structure of a round tube welding device in an embodiment.

[0056] In this embodiment, if Figure 6 As shown, the round tube welding device includes a clamping mechanism 10 , an auxiliary supporting mechanism 20 and a welding mechanism 30 .

[0057] The auxiliary support mechanism 20 can support the plate to be processed and drive the plate to be processed to rotate.

[0058] The auxiliary support mechanism 20 may be a support structure disposed at one side of the clamping mechanism 10 and capable of receiving the plate to be processed and rotating and transporting the plate to be processed toward the clamping mechanism 10 .

[0059] The clamping mechanism 10 is disposed on one side of the auxiliary supporting mechanism 20 and can clamp and act on the first end surface and the second end surface of the plate to be processed.

[0060] The welding mechanism 30 can weld the clamped first end surface and second end surface.

[0061] The welding mechanism 30 may be a welding head assembly capable of adjusting the welding position in multiple directions. The welding mechanism 30 includes an XYZ three-axis motion assembly 320 and a welding laser 340. The XYZ three-axis motion assembly 320 may drive the welding laser 340 to move precisely in three-dimensional space. The welding laser 340 may be a laser emitting device capable of converting electrical energy into light energy and emitting laser beams of different wavelengths according to different working media.

[0062] Continue reading Figure 6 The round tube welding device also includes a water chiller 40, a smoke purifier 50, a voltage-stabilized power supply 60, a gas circuit integrated cabinet 70 and an electrical control cabinet 80. Among them, the water chiller 40 can be a heat dissipation structure that can provide constant temperature and constant flow cooling water for the welding mechanism 30 to ensure the normal and stable operation of the welding mechanism 30. The voltage-stabilized power supply 60 can be a power supply circuit or power supply equipment that stabilizes the power supply voltage with large fluctuations or that does not meet the requirements of the electrical equipment within a set value range, so that various circuits or electrical equipment can work normally under the rated working voltage. The gas circuit integrated cabinet 70 can be a gas circuit processing structure that can ensure the dryness and purity of the cross-blowing gas and the welding shielding gas.

[0063] Alternatively, if Figure 7 As shown, the auxiliary support mechanism 20 is provided with a plurality of rotating support assemblies 220 which are surrounded in the vertical direction. The height of the rotating support assemblies 220 in the vertical direction is smaller than the height of the clamping mechanism 10 in the vertical direction, so that the clamping mechanism 10 can receive the plate to be processed conveyed by the auxiliary support mechanism 20, thereby improving the transmission efficiency of the plate to be processed between the auxiliary support mechanism 20 and the clamping mechanism 10, and the distance between the plurality of rotating support assemblies 220 which are distributed in a circle can be adjusted according to the target welding round pipe diameter, thereby improving the support application range and support effect of the auxiliary support mechanism 20.

[0064] The rotating support assembly 220 includes a rotating guide wheel 2220, a guide wheel bracket 2240 and a rod-shaped auxiliary support member 2260. The rotating guide wheel 2220 surrounds the central axis of the rotating support assembly 220 in the vertical direction and can abut against the surface of the plate to be processed. The rod-shaped auxiliary support member 2260 is arranged on the guide wheel bracket 2240 in the vertical direction.

[0065] The rotating support assembly 220 may be a rotating structure in which a rod-shaped auxiliary support member 2260 is arranged around in a vertical direction and can drive the plate to be processed to rotate and adjust its position. The rotating guide wheel 2220 may be a pulley arranged on the top of the guide wheel bracket 2240 and can abut against the surface of the plate to be processed and can drive the plate to be processed to rotate and adjust its position under the action of sliding friction. The rod-shaped auxiliary support member 2260 may be a long strip support member arranged on a plurality of guide wheel brackets 2240 in a vertical direction and can constrain the rotation trajectory of the plate to be processed.

[0066] The round tube welding device provided in this embodiment loads the plate to be processed to the left side of the fixture bearing seat 120 through the auxiliary support mechanism 20, controls the positioning pin of the fixture bearing seat 120 to extend, aligns the front end surface of the plate with the positioning pin, controls the left clamp cylinder of the front pressing fixture 140 to extend, and after positioning is completed, controls the positioning pin of the fixture bearing seat 120 to retract, fixes the left side of the round tube and transports the right side of the plate, aligns the front and rear ends of the plate, and controls the right clamp cylinder of the front pressing fixture 140 to extend and press. After the pressing is completed, the control software of the control console is controlled to find the coordinates of the welding start and end points, edit them into the CNC program, set the welding speed and laser power, start the welding laser 340 to emit light for welding, and then controls the left and right clamping cylinders of the front pressing fixture 140 to retract, and transport the welding product to the storage position, and the whole welding process is completed.

[0067] The present application also provides a round tube welding device, which includes the round tube welding device in the above embodiment.
