[0033] See also Figure 1 and Figure 2 , the positioning device provided in the embodiment of the present application is now described. The positioning device provided in the embodiment of the present application includes a first positioning mechanism 1, the first positioning mechanism 1 is used to position the first workpiece, the first positioning mechanism 1 includes a first moving member 11, a first positioning member 12 and a stripping member 13, the first positioning member 12 is provided with a limiting groove 121 for accommodating the first workpiece, a positioning portion 122 is provided in the limiting groove 121, the positioning portion 122 is connected to the first workpiece to position the first workpiece, the first moving member 11 is transmission-connected with the first positioning member 12 to drive the first positioning member 12 to approach or move away from the welding station of the first workpiece, and the stripping member 13 is used to push the first workpiece out of the limiting groove 121.

[0034] The first workpiece in the embodiment of the present application may specifically be a strip-shaped workpiece such as a beam.

[0035] The first moving member 11 may specifically be a linear motor, a cylinder or a hydraulic cylinder.

[0036] The positioning portion 122 on the first positioning member 12 can be a latch or a magnetic member, preferably a latch. A pin hole is provided on the first workpiece, and the latch is inserted into the pin hole on the first workpiece to accurately position the first workpiece in the limiting groove 121 of the first positioning member 12. In this way, the positioning portion 122 of the first limiting groove 121 allows the first workpiece to be fixed in the same position each time, thereby improving the welding accuracy.

[0037] The stripping member 13 may be an elastic member disposed in the limiting groove 121, and may be a spring or elastic silicone. The stripping member 13 prevents the first movable member 11 from pulling the first positioning member 12 away from the welding station of the first workpiece, thereby causing the first workpiece to deform.

[0038] The workflow implemented in this application is as follows: the first workpiece is placed in the limiting groove 121 of the first positioning member 12, and the first workpiece is positioned in the first limiting groove 121 by the positioning portion 122 in the first limiting groove 121, and then the first moving member 11 drives the first positioning member 12 to approach the welding position of the first workpiece. After the welding process of the first workpiece is completed, the stripping member 13 can push the first workpiece out of the limiting groove 121.

[0039] Preferably, see Figure 3 and Figure 4 The stripping member 13 includes a stripping driving portion 131 and a pushing portion 132 . The stripping driving portion 131 is transmission-connected with the pushing portion 132 to drive the pushing portion 132 to approach or move away from the first workpiece. The pushing portion 132 is used to contact the first workpiece.

[0040] The stripping drive unit 131 in the embodiment of the present application may be a linear motor or a cylinder. The pushing unit 132 may be a push plate extending into the limiting groove 121. After the first workpiece welding process is completed, the stripping drive unit drives the pushing unit 132 to push the first workpiece out of the limiting groove 121.

[0041] Preferably, an insertion hole is provided in the limiting groove 121 , and the pushing portion 132 can be inserted into the insertion hole to contact the first workpiece in the limiting groove 121 .

[0042] The pushing portion 132 can be specifically a pin inserted into the insertion hole. The pushing portion 132 of the stripping member 13 is inserted into the insertion hole of the limiting groove 121, and the first workpiece can be pushed out of the limiting groove 121. When the first workpiece is in the shape of a strip, the limiting groove 121 of the first positioning member 12 can also be set in the shape of a strip according to the shape of the first workpiece, and the insertion holes can be evenly arranged along the length direction of the limiting groove 121. The stripping member 13 can be arranged according to the number of the insertion holes, so that the first workpiece can be prevented from being damaged due to uneven force.

[0043] See also Figure 1 The first positioning mechanism 1 further includes a second moving member 14, which is transmission-connected to the first moving member 11 to drive the first positioning member 12 to approach or move away from the welding station of the first workpiece.

[0044] The second moving member 14 may specifically be a linear motor, a cylinder, or a moving module driven by a motor.

[0045] The second moving member 14 can increase the distance between the first workpiece and the welding station, making it easier to place the first workpiece into the limiting groove 121 on the first positioning member 12 .

[0046] See also Figure 5 The positioning device also includes a reference mechanism 2 for supporting the second workpiece. The first positioning mechanism 1 and the reference mechanism 2 are arranged on both sides of the second workpiece opposite to each other. The first positioning mechanism 1 is used to position the first workpiece on the side wall of the second workpiece.

[0047] The second workpiece in the embodiment of the present application may specifically be a barrel section or other workpieces to be welded.

[0048] The positioning device in the embodiment of the present application is used to position the first workpiece on the second workpiece, and then weld the first workpiece to the second workpiece through the welding device.

[0049] After the second workpiece is pressed against the reference mechanism 2, the first positioning mechanism 1 moves toward the reference mechanism 2, so that the first workpiece on the first positioning member 12 is pressed against the side wall of the second workpiece, and then the first workpiece is welded to the second workpiece to complete the welding process.

[0050] Preferably, the reference mechanism 2 includes a third movable member 21 and a support member 22.

The support member 22 is provided with a contoured groove 221 that matches the second workpiece, and the support member 22 is used to support the second workpiece.

[0051] The third moving member 21 can be a linear motor, a cylinder or a moving module driven by a motor. The supporting member 22 can be a plate or a block. After the second workpiece is fixed, the third moving member 21 drives the supporting member 22 to move toward the side wall of the second workpiece, so that the contoured groove 221 on the supporting member 22 abuts against the side wall of the second workpiece to support the second workpiece and prevent the second workpiece from deforming during the welding process.

[0052] The reference mechanism 2 also includes a first connecting member 23, which is arranged at the end of the support member 22.

The first connecting member 23 is connected to the second connecting member 15 to prevent the end of the support member 22 or the end of the first positioning member 12 from deforming.

[0053] When the height of the first workpiece and the second workpiece is high, the ends of the support member 22 and the first positioning member 12 are easily deformed due to lack of connection and fixation, thereby affecting the welding effect. The first connecting member 23 and the second connecting member 15 connect the ends of the support member 22 and the first positioning member 12, preventing the ends of the support member 22 and the first positioning member 12 from deforming and improving the welding effect.

[0054] The first connecting member 23 in the embodiment of the present application may specifically include a rotating portion and a first connecting portion, and the rotating portion is transmission-connected with the first connecting portion to drive the first connecting portion to rotate toward or away from the first positioning member 12. A plug hole is provided on the first connecting portion.

[0055] The second connecting member 15 may specifically include a moving portion and a second connecting portion, and the moving portion is transmission-connected with the second connecting portion to drive the second connecting portion to approach or move away from the first connecting portion.

[0056] The rotating part of the first connecting member 23 drives the first connecting member to rotate toward the first positioning member 12 , and the moving part of the second connecting member 15 drives the second connecting member to approach the first connecting member, so that the second connecting member is inserted into the insertion hole of the first connecting member.

[0057] See also Figure 6 The positioning device also includes a rotating support assembly 3, which is used to support and rotate the second workpiece.

[0058] When the first workpiece needs to be welded to the second workpiece in batches, the rotating support assembly 3 can rotate the second workpiece, which facilitates the batch welding of the first workpiece and improves work efficiency.

[0059] The rotating supporting assembly 3 includes a rotating driving member 31, a supporting member 32 and a second positioning member 33. The supporting member 32 is provided with a positioning groove 321 for accommodating the second workpiece. The second positioning member 33 is provided on the supporting member 32 to position the second workpiece. The rotating driving member 31 is transmission-connected with the supporting member 32 to drive the supporting member 32 to rotate.

[0060] The rotating driving member 31 may be a rotating motor or a rotating cylinder. The supporting member 32 may be a rotating disk, on which a positioning groove 321 matching the side wall of the second workpiece is provided. The second positioning member 33 may be a fixture or a positioning cylinder. The second positioning member 33 is provided on both sides of the positioning groove 321 to push the second workpiece to move toward the center of the rotating disk, so that the second workpiece abuts against a side wall of the positioning groove 321, thereby realizing the centering positioning of the second workpiece.

[0061] An embodiment of the present application also provides a laser processing device, including the above-mentioned positioning device.

[0062] Since the laser processing equipment of the embodiment of the present application includes the positioning device in any of the above embodiments, it has the beneficial effects brought by the positioning device in any of the above embodiments, which will not be elaborated here.

[0063] The laser processing equipment of the embodiment of the present application further comprises a laser device, which comprises a fourth moving part and a laser part. The fourth moving part is in transmission connection with the laser part to drive the laser part to weld the first workpiece to the second workpiece along the length direction of the first workpiece.

[0065] The working principle / process of the laser processing equipment provided in the embodiment of the present application is as follows:

[0066] The staff hoisted the barrel section into the positioning groove 321 of the supporting member 32 of the rotating supporting assembly 3, and the second positioning member 33 pushed the barrel section to move toward the center of the supporting member 32, so that the inner wall of the barrel section abutted against the side wall of the positioning groove 321, thereby realizing the centering positioning of the barrel section.

[0067] The first positioning mechanism 1 is arranged on the inner side of the barrel section. The staff puts the stringer into the limiting groove 121 of the first positioning member 12, and positions the stringer in the limiting groove 121 through the positioning portion 122 in the limiting groove 121. Then, the second moving member 14 drives the first moving member 11 and the first positioning member 12 to move toward the inner side wall of the barrel section. The first moving member 11 drives the first positioning member 12 to approach the welding station of the barrel section, and the stringer on the first positioning member 12 is pressed against the inner side wall of the barrel section. At the same time, the third moving member 21 of the reference mechanism 2 drives the support member 22 to move toward the outer side wall of the barrel section, so that the contoured groove 221 on the support member 22 is pressed against the outer side wall of the barrel section to support the barrel section, and the first connecting member 23 is connected to the second connecting member 15.

[0068] Next, the fourth moving part of the laser device drives the laser part along the length direction of the beam to weld the beam to the inner side wall of the barrel section.
