Figure 1 A single arc-shaped mesh includes an inner arc steel bar 101, an outer arc steel bar 102, and a transverse bar 103 disposed between the inner arc steel bar 101 and the outer arc steel bar 102. The folded edge formed by bending both ends of the inner arc steel bar 101 to the same side is welded to both ends of the outer arc steel bar 102 to form the frame of the arc-shaped mesh. Multiple transverse bars 103 are welded at intervals between the inner arc steel bar 101 and the outer arc steel bar 102 to form the arc-shaped mesh.

[0060] Example 1

[0061] See Figure 1 The arc-shaped mesh includes an inner arc steel bar 101, an outer arc steel bar 102, and transverse bars 103 disposed between the inner arc steel bar 101 and the outer arc steel bar 102. The folded edge formed by bending both ends of the inner arc steel bar 101 to the same side is welded to both ends of the outer arc steel bar 102 to form the frame of the arc-shaped mesh. Multiple transverse bars 103 are welded at intervals between the inner arc steel bar 101 and the outer arc steel bar 102 to form the arc-shaped mesh.

[0062] The outer arc-shaped steel bar 102 is arc-shaped.

[0063] The inner arc steel bar 101 includes an arc edge 1011, and both ends of the arc edge 1011 are provided with folded edges 1012. The free ends of the two folded edges 1012 are welded to the two ends of the outer arc steel bar 102 respectively.

[0064] To ensure the welding quality of the arc-shaped mesh, and to position the inner arc-shaped reinforcing bars 101 and 102 during welding, please refer to [reference needed]. Figures 2-4 This embodiment provides a positioning mechanism for welding arc-shaped mesh.

[0065] Specifically, the positioning mechanism for welding arc-shaped mesh includes a frame 1, an inner arc rebar positioning component 2, and an outer arc rebar positioning component 3.

[0066] The inner arc rebar positioning component 2 is mounted on the frame 1 and includes a first positioning groove 211 for positioning the inner arc rebar 101.

[0067] The outer arc rebar positioning component 3 is mounted on the frame 1 and includes a second positioning groove 311 for positioning the outer arc rebar 102.

[0068] The positioning mechanism for welding the arc-shaped mesh provided in this embodiment uses the inner arc rebar positioning component 2 to position the inner arc rebar 101. To position the inner arc rebar 101, simply place it in the first positioning groove 211. The outer arc rebar positioning component 3 is used to position the outer arc rebar 102. To position the outer arc rebar 102, simply place it in the second positioning groove 311. After positioning the inner arc rebar 101 and outer arc rebar 102, welding is performed between them. During the welding of one joint, due to the presence of the inner arc rebar positioning component 2 and the outer arc rebar positioning component 3, the positions of the inner arc rebar 101 and outer arc rebar 102 remain unchanged. Therefore, when welding the other joint, there is no gap at the joint, ensuring the welding quality of the inner arc rebar 101 and outer arc rebar 102, and thus ensuring the welding quality of the arc-shaped mesh.

[0069] Alternatively, the welding operation can be performed manually or by a welding robot.

[0070] Specifically, in this embodiment, the bottom of the first positioning groove 211 and the bottom of the second positioning groove 311 are coplanar, so that the inner arc steel bar 101 and the outer arc steel bar 102 can be positioned at the same height, ensuring the flatness of the arc mesh.

[0071] Specifically, in this embodiment, the inner arc rebar positioning component 2 includes a plurality of first positioning pieces 21. Each first positioning piece 21 is provided with a first positioning groove 211 with an opening at the upper end. The plurality of first positioning pieces 21 are divided into three groups. The plurality of first positioning pieces 21 in the first group are distributed along an arc shape and are used to position the arc edge 1011 of the inner arc rebar 101. The plurality of first positioning pieces 21 in the second group are distributed along a straight line and are used to position one folded edge 1012 of the inner arc rebar 101. The plurality of first positioning pieces 21 in the third group are distributed along a straight line and are used to position the other folded edge 1012 of the inner arc rebar 101.

[0072] Specifically, the upper opening of the first positioning groove 211 is flared to facilitate the direct entry of the inner arc reinforcing bar 101 into the first positioning groove 211. The lower end of the first positioning groove 211 is divided into a positioning section, the size of which can be larger than or equivalent to the diameter of the inner arc reinforcing bar 101.

[0073] Optionally, in this embodiment, the number of first positioning pieces 21 in the first group is 7; the number of first positioning pieces 21 in the second group is 2; and the number of first positioning pieces 21 in the third group is 2.

[0074] Specifically, in this embodiment, the outer arc rebar positioning component 3 includes a plurality of second positioning pieces 31, each of which is provided with a second positioning groove 311 with an opening at the upper end, and the plurality of second positioning pieces 31 are spaced apart along the arc.

[0075] Specifically, the upper opening of the second positioning groove 311 is flared to facilitate the direct entry of the outer arc reinforcing bar 102 into the second positioning groove 311. The lower end of the second positioning groove 311 is divided into a positioning section, the size of which can be larger than or equivalent to the diameter of the outer arc reinforcing bar 102.

[0076] Furthermore, in order to position the transverse ribs 103 before welding, in this embodiment, the positioning mechanism for welding the arc mesh also includes a transverse rib positioning component 7. The transverse rib positioning component 7 is configured to correspond one-to-one with the transverse ribs 103 of the arc mesh. The transverse rib positioning component 7 includes a third positioning groove 711 for positioning the transverse ribs 103.

[0077] Specifically, in this embodiment, the transverse rib positioning component 7 includes a plurality of third positioning pieces 71 distributed along a straight line, and each third positioning piece 71 is provided with a third positioning groove 711 with an opening at the upper end.

[0078] Specifically, the upper opening of the third positioning groove 711 is flared to facilitate the direct insertion of the transverse rib 103 into the third positioning groove 711. The lower end of the third positioning groove 711 is divided into a positioning section, the size of which can be larger than or equal to the diameter of the transverse rib 103.

[0079] Furthermore, in order for the transverse rib positioning assembly 7 to be able to position transverse ribs 103 of different diameters, the size of the positioning section of the third positioning groove 711 is larger than the diameter of the transverse rib 103 with the largest diameter, or the size of the positioning section of the third positioning groove 711 is equal to the diameter of the transverse rib 103 with the largest diameter.

[0080] More specifically, in order to prevent the transverse rib 103 from moving radially after it falls into the third positioning groove 711, in this embodiment, see... Figures 4-6 The transverse rib positioning component 7 also includes an elastic snap-fit ​​component 72, which has an elastic clamping groove 721 that can snap into the transverse rib 103.

[0081] As the horizontal rib 103 falls into the third positioning groove 711, the horizontal rib 103 is also engaged in the elastic clamping groove 721.

[0082] Specifically, in this embodiment, the transverse rib positioning component 7 includes two spaced third positioning pieces 71, each of which is provided with a third positioning groove 711, and an elastic snap-fit ​​member 72 is provided between the two third positioning pieces 71.

[0083] More specifically, in this embodiment, the elastic snap-fit ​​member 72 includes a base plate 722, and each of the two ends of the base plate 722 is provided with a spring piece 723, with the two spring pieces 723 arranged opposite to each other. The base plate 722 is fixedly mounted on the frame 1.

[0084] The spring clip 723 includes a first elastic segment 7231 and a second elastic segment 7232. The first end of the first elastic segment 7231 is connected to the substrate 722, and the second end of the first elastic segment 7231 is connected to the second elastic segment 7232. The second segments of the two first elastic segments 7231 are close to each other to form an elastic groove 721, and the free ends of the two second elastic segments 7232 are far apart to form a flared structure, so that the transverse rib 103 can be smoothly engaged into the elastic groove 721.

[0085] Specifically, in this embodiment, the elastic snap-fit ​​component 72 is integrally formed from spring steel.

[0086] Preferably, in this embodiment, the size of the positioning section at the lower end of the first positioning groove 211 is larger than the diameter of the inner arc steel bar 101, so that the positioning mechanism for welding the arc mesh can be adapted to inner arc steel bars 101 of different diameters.

[0087] To ensure accurate positioning of inner arc reinforcing bars 101 of different sizes, please refer to... Figure 3 , Figure 4 and Figure 8In this embodiment, the positioning mechanism for welding arc mesh also includes an inner arc steel bar edge adjustment component 4, which includes a first driving component 42 and a first pushing component 41.

[0088] The first driving component 42 is fixedly mounted on the frame 1.

[0089] The first pusher 41 is disposed at the output end of the first drive member 42. The first pusher 41 can push the arc edge 1011 of the inner arc steel bar 101 to move along the first set direction until the arc edge 1011 abuts against the side of the first positioning groove 211 that cooperates with the arc edge 1011.

[0090] Specifically, with Figure 3 Taking the orientation shown as an example, when the arc edge 1011 falls into the first positioning groove 211, the first driving member 42 drives the first pushing member 41 to move. The first pushing member 41 pushes the arc edge 1011 of the inner arc steel bar 101 to move along the first set direction until the arc edge 1011 abuts against the relatively outer side of the first positioning groove 211 that cooperates with the arc edge 1011.

[0091] Furthermore, in order to ensure that the first pusher 41 pushes the arc edge 1011 of the inner arc steel bar 101 along the first set direction, a first guide groove 11 is provided on the frame 1 to slide and cooperate with the first pusher 41, and the first guide groove 11 extends along the first set direction.

[0092] Optionally, in this embodiment, the first pusher 41 is a cylinder. The side of the first pusher 41 is provided with a first groove that engages with the arc edge 1011.

[0093] Furthermore, the positioning mechanism for welding arc mesh also includes an inner arc steel bar folding edge adjustment component 5, which includes a second driving component and a second pushing component 51.

[0094] The second drive component is fixedly mounted on the frame 1.

[0095] The second pusher 51 is disposed at the output end of the second drive member. The second pusher 51 can push the folded edge 1012 of the inner arc steel bar 101 to move along the second set direction until the folded edge 1012 abuts against the side of the first positioning groove 211 that cooperates with the folded edge 1012.

[0096] Specifically, with Figure 3 Taking the orientation shown as an example, when the folded edge 1012 falls into the first positioning groove 211, the second driving member pushes the second pushing member 51, and the second pushing member 51 pushes the folded edge 1012 of the inner arc steel bar 101 to move along the second set direction until the folded edge 1012 abuts against the relatively inner side of the first positioning groove 211 that cooperates with the folded edge 1012.

[0097] Optionally, in this embodiment, the second driving member is a cylinder; the side of the second pushing member 51 is provided with a second slot that cooperates with the folded edge 1012.

[0098] Furthermore, in this embodiment, in order to ensure that the second pusher 51 pushes the inner arc steel bar 101 along the second set direction, the frame 1 is provided with a second guide groove 12 that slides with the second pusher 51, and the second guide groove 12 extends along the second set direction.

[0099] Furthermore, in this embodiment, in order to enable the positioning mechanism for welding the arc-shaped mesh to adapt to outer arc reinforcing bars 102 of different diameters, the size of the positioning section of the second positioning groove 311 is always larger than the diameter of the outer arc reinforcing bar 102.

[0100] To prevent the outer arc reinforcing bars 102 of different diameters from moving radially after falling into the second positioning groove 311, in this embodiment, see... Figure 3 The positioning mechanism for welding arc mesh also includes an outer arc steel bar adjustment component 6, which includes a third driving component and a third pushing component 61.

[0101] The third drive component is fixedly mounted on frame 1.

[0102] The third pusher 61 is located at the output end of the third drive member and can push the outer arc steel bar 102 to move along the third set direction until the outer arc steel bar 102 abuts against the side of the second positioning groove 311.

[0103] Specifically, with Figure 3 Taking the orientation shown as an example, when the outer arc steel bar 102 falls into the second positioning groove 311, the third driving member drives the third pushing member 61 to move until the outer arc steel bar 102 abuts against the relatively outer side of the second positioning groove 311.

[0104] Optionally, in this embodiment, the third driving component is a cylinder. The side of the third pushing component 61 is provided with a third slot that mates with the outer arc reinforcing bar 102.

[0105] Furthermore, in order to ensure that the third pusher 61 pushes the outer arc steel bar 102 along the third set direction, the frame is provided with a third guide groove 13 that slides with the third pusher 61, and the third guide groove 13 extends along the third set direction.

[0106] In this embodiment, the inner arc rebar edge adjustment component 4, the inner arc rebar folding edge adjustment component 5, and the outer arc rebar adjustment component 6 are provided so that the positioning mechanism for welding the arc mesh can be adapted to inner arc rebars 101 of different diameters and outer arc rebars 102 of different diameters, and the outline dimensions of the arc mesh welded on the positioning mechanism for welding the arc mesh are guaranteed to be consistent.

[0107] Optionally, in this embodiment, there are multiple inner arc rebar edge adjustment components 4 and multiple outer arc rebar adjustment components 6.

[0108] Each folded edge 1012 is provided with an inner arc steel bar folded edge adjustment component 5, which can push the folded edge 1012 relatively inward.

[0109] Furthermore, after the arc-shaped mesh is welded, it needs to be transferred away. In this embodiment, see... Figure 4 and Figure 8 The positioning mechanism for welding arc-shaped mesh also includes an arc-shaped mesh ejection assembly 8, which includes a fourth driving member 81 and an ejection member 82.

[0110] The fourth drive component 81 is fixedly mounted on the frame 1.

[0111] The ejector 82 is located at the output end of the fourth drive member 81. The ejector 82 can push the welded arc-shaped mesh away from the arc-shaped mesh welding positioning mechanism.

[0112] Optionally, in this embodiment, the fourth driving member 81 is a cylinder. The fourth driving member 81 is disposed on the lower surface of the frame 1. When the ejector 82 is not in operation, it is also located on the lower surface of the frame 1.

[0113] The push-out component 82 is U-shaped and includes a connecting arm 821 and two lifting arms 822. The connecting arm 821 is connected to the output end of the fourth drive component 81, and the two lifting arms 822 are fixedly connected to both ends of the connecting arm 821, with the lifting arms 822 arranged perpendicularly to the connecting arm 821. One of the lifting arms 822 can rise to abut against the outer arc reinforcing bar 102, and the other lifting arm 822 can rise to abut against the arc edge 1011 of the inner arc reinforcing bar 101.

[0114] When it is necessary to push the welded arc-shaped mesh away from the arc-shaped mesh welding positioning mechanism, the fourth driving member 81 drives the pusher 82 to rise in the vertical direction. When the two lifting arms 822 of the pusher 82 rise to abut against the arc-shaped mesh, the pusher 82 continues to rise until the arc-shaped mesh is separated from the first positioning groove 211 and the second positioning groove 311.

[0115] Furthermore, the frame 1 is provided with perforations for the lifting arm 822 to pass through.

[0116] Optionally, in this embodiment, the number of arc-shaped mesh extension components 8 is several; it can be two or more, depending on the need.

[0117] For example, in this embodiment, the positioning mechanism for welding arc-shaped wire mesh is used as follows:

[0118] Place the inner arc steel bar 101 and the outer arc steel bar 102 into position, control the inner arc steel bar edge adjustment component 4, the inner arc steel bar folding edge adjustment component 5 and the outer arc steel bar adjustment component 6 to complete the action, and place multiple horizontal bars 103 into position one by one.

[0119] Complete the welding of the two butt joints of the inner arc steel bar 101 and the outer arc steel bar 102; complete the welding of multiple horizontal bars 103 one by one;

[0120] Reset the inner arc steel bar edge adjustment component 4, the inner arc steel bar folding edge adjustment component 5, and the outer arc steel bar adjustment component 6;

[0121] The control unit 8 pushes the arc-shaped mesh out of the welding positioning mechanism.

[0122] Specifically, the inner arc reinforcing bars 101, outer arc reinforcing bars 102, and transverse reinforcing bars 103 can be placed manually or mechanically.

[0123] Example 2

[0124] See Figure 9 This embodiment provides a welding device for arc-shaped wire mesh, which can automatically complete the welding of arc-shaped wire mesh and improve work efficiency.

[0125] Specifically, in this embodiment, the welding equipment for the arc-shaped mesh includes the positioning mechanism for welding the arc-shaped mesh and the welding robot 50 as described in Embodiment 1.

[0126] The welding robot 50 is capable of welding curved mesh panels.

[0127] The arc-shaped mesh welding equipment provided in this embodiment uses a positioning mechanism to position the un-welded arc-shaped mesh during operation, thereby completing the welding of the arc-shaped mesh. The welding quality and welding efficiency are both good.

[0128] When using the positioning mechanism for welding arc-shaped wire mesh, the inner arc rebar positioning component 2 is used to position the inner arc rebar 101; when positioning the inner arc rebar 101, it is simply placed in the first positioning groove 211. The outer arc rebar positioning component 3 is used to position the outer arc rebar 102; when positioning the outer arc rebar 102, it is simply placed in the second positioning groove 311. After positioning the inner arc rebar 101 and the outer arc rebar 102, welding is then performed between them; during the welding of one joint, due to the presence of the inner arc rebar positioning component 2 and the outer arc rebar positioning component 3, the positions of the inner arc rebar 101 and the outer arc rebar 102 remain unchanged. Therefore, when welding the other joint, there is no gap at the joint, ensuring the welding quality of the inner arc rebar 101 and the outer arc rebar 102, and thus ensuring the welding quality of the arc-shaped wire mesh.

[0129] Specifically, the welding robot 50 includes a slide rail and a welding robot body that is slidably mounted on the slide rail.

[0130] Furthermore, in this embodiment, the welding equipment for the arc-shaped mesh also includes an arc-shaped mesh transfer component 30 and an arc-shaped mesh storage component 40.

[0131] The arc-shaped mesh transfer unit 30 can transfer the arc-shaped mesh that has been welded on the arc-shaped mesh welding positioning mechanism to the arc-shaped mesh storage unit 40.

[0132] Specifically, in this embodiment, the arc-shaped mesh transfer component 30 is a logistics hoist.

[0133] More preferably, the number of positioning mechanisms for welding the arc-shaped mesh is at least two.

[0134] Specifically, in this embodiment, there are two positioning mechanisms for welding arc-shaped mesh, which are located on both sides of the welding robot 50.

[0135] Furthermore, in this embodiment, the welding equipment for the arc-shaped mesh also includes an inner arc rebar storage rack 20, an outer arc rebar storage rack 60, and a transverse rebar storage rack 70. The processed inner arc rebar 101 is placed on the inner arc rebar storage rack 20, the processed outer arc rebar 102 is placed on the outer arc rebar storage rack 60, and the processed transverse rebar 103 is placed on the transverse rebar storage rack 70.

[0136] For example, in this embodiment, the working process of the welding equipment for the arc-shaped wire mesh is as follows:

[0137] The processed inner arc steel bar 101 is placed on the inner arc steel bar storage rack 20, the processed outer arc steel bar 102 is placed on the outer arc steel bar storage rack 60, and the processed transverse steel bar 103 is placed on the transverse steel bar storage rack 70.

[0138] Position the inner arc steel bar 101, outer arc steel bar 102, and horizontal bar 103 on the positioning mechanism for welding arc mesh; (the inner arc steel bar 101, outer arc steel bar 102, and horizontal bar 103 on both positioning mechanisms for welding arc mesh are in place).

[0139] The welding robot 50 is controlled to complete the welding of one of the arc-shaped mesh panels on the positioning mechanism.

[0140] Control the welding robot 50 to switch stations and complete the welding of another arc-shaped mesh on the positioning mechanism;

[0141] Control the resetting of the inner arc rebar edge adjustment component 4, the inner arc rebar folding edge adjustment component 5, and the outer arc rebar adjustment component 6; control the action of the arc mesh push-out component 8 to push the completed arc mesh away from the arc mesh welding positioning mechanism;

[0142] The arc-shaped mesh transfer component 30 is controlled to grab the welded arc-shaped mesh and place it on the arc-shaped mesh storage component 40.
