[0060] Embodiment 1

[0061] See also Figure 1 The arc mesh includes an inner arc steel bar 101, an outer arc steel bar 102 and a transverse bar 103 arranged between the inner arc steel bar 101 and the outer arc steel bar 102. The two ends of the inner arc steel bar 101 are bent to the same side to form a folded edge and the two ends of the outer arc steel bar 102 are welded to form a frame of the arc mesh. A plurality of transverse bars 103 are welded between the inner arc steel bar 101 and the outer arc steel bar 102 at intervals to form an arc mesh.

[0062] The outer arc 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 a folded edge 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] In order to position the inner arc steel bar 101 and the outer arc steel bar 102 during welding and ensure the welding quality of the arc mesh, refer to Figure 2-Figure 4 , this embodiment provides a positioning mechanism for arc mesh welding.

[0065] Specifically, the arc mesh welding positioning mechanism includes a frame 1, an inner arc steel bar positioning assembly 2 and an outer arc steel bar positioning assembly 3.

[0066] The inner arc steel bar positioning assembly 2 is arranged on the frame 1 and includes a first positioning groove 211 for positioning the inner arc steel bar 101 .

[0067] The outer arc steel bar positioning assembly 3 is arranged on the frame 1 , and includes a second positioning groove 311 for positioning the outer arc steel bar 102 .

[0068] When the arc mesh welding positioning mechanism provided in this embodiment is used, the inner arc steel bar positioning assembly 2 is used to position the inner arc steel bar 101; when positioning the inner arc steel bar 101, the inner arc steel bar 101 can be placed in the first positioning groove 211. The outer arc steel bar positioning assembly 3 is used to position the outer arc steel bar 102; when positioning the outer arc steel bar 102, the outer arc steel bar 102 can be placed in the second positioning groove 311. After the positioning of the inner arc steel bar 101 and the outer arc steel bar 102 is completed, the welding between the two is performed; in the process of welding one joint of the two, due to the presence of the inner arc steel bar positioning assembly 2 and the outer arc steel bar positioning assembly 3, the positions of the inner arc steel bar 101 and the outer arc steel bar 102 are always kept unchanged, so when welding is performed at another joint, there is no gap at the joint, which ensures the welding quality of the inner arc steel bar 101 and the outer arc steel bar 102, and further ensures the welding quality of the arc mesh.

[0069] Optionally, 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 arranged coplanarly so that the inner arc steel bar 101 and the outer arc steel bar 102 can be positioned at the same height to ensure the flatness of the arc mesh.

[0071] Specifically, in this embodiment, the inner arc steel bar positioning assembly 2 includes a plurality of first positioning pieces 21, each of which is provided with a first positioning groove 211 having an opening at the upper end, and the plurality of first positioning pieces 21 are divided into three groups, wherein the plurality of first positioning pieces 21 of the first group are distributed along an arc shape, for positioning the arc edge 1011 of the inner arc steel bar 101; the plurality of first positioning pieces 21 of the second group are distributed along a straight line, for positioning a folded edge 1012 of the inner arc steel bar 101; the plurality of first positioning pieces 21 of the third group are distributed along a straight line, for positioning the other folded edge 1012 of the inner arc steel bar 101.

[0072] Specifically, the upper opening of the first positioning groove 211 is flared, so that the inner arc steel bar 101 can be directly placed in the first positioning groove 211. The lower end of the first positioning groove 211 is divided into a positioning section, the size of which is larger than the diameter of the inner arc steel bar 101 or equal to the diameter of the inner arc steel bar 101.

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

[0074] Specifically, in this embodiment, the outer arc steel bar positioning assembly 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 line.

[0075] Specifically, the upper end opening of the second positioning groove 311 is flared, so that the outer arc steel bar 102 can fall directly 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 is larger than the diameter of the outer arc steel bar 102 or equal to the diameter of the outer arc steel bar 102.

[0076] Furthermore, in order to position the transverse reinforcement 103 before welding, in this embodiment, the positioning mechanism for arc mesh welding also includes a transverse reinforcement positioning assembly 7, and the transverse reinforcement positioning assembly 7 is arranged one-to-one corresponding to the transverse reinforcement 103 of the arc mesh. The transverse reinforcement positioning assembly 7 includes a third positioning groove 711 for positioning the transverse reinforcement 103.

[0077] Specifically, in this embodiment, the transverse rib positioning assembly 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 end opening of the third positioning groove 711 is flared, so that the transverse rib 103 can directly fall 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 is larger than the diameter of the transverse rib 103 or equal to the diameter of the transverse rib 103.

[0079] Furthermore, in order to enable the transverse rib positioning assembly 7 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 in its radial direction after the transverse rib 103 falls into the third positioning groove 711, in this embodiment, Figure 4-Figure 6The transverse rib positioning assembly 7 further includes an elastic clamping member 72 , on which an elastic clamping groove 721 capable of clamping with the transverse rib 103 is provided.

[0081] When the transverse rib 103 falls into the third positioning groove 711 , the transverse rib 103 is also clamped in the elastic clamping groove 721 .

[0082] Specifically, in this embodiment, the transverse rib positioning assembly 7 includes two third positioning pieces 71 that are spaced apart from each other. Each third positioning piece 71 is provided with a third positioning groove 711 , and an elastic clamping member 72 is provided between the two third positioning pieces 71 .

[0083] More specifically, in this embodiment, the elastic clamping member 72 includes a bottom plate 722 , and two sections of the bottom plate 722 are each provided with an elastic sheet 723 , and the two elastic sheets 723 are arranged opposite to each other. The bottom plate 722 is fixedly arranged on the frame 1 .

[0084] The spring piece 723 includes a first elastic section 7231 and a second elastic section 7232. The first end of the first elastic section 7231 is connected to the bottom sheet 722, and the second end of the first elastic section 7231 is connected to the second elastic section 7232. The second sections of the two first elastic sections 7231 are close to each other to form an elastic clip groove 721, and the free ends of the two second elastic sections 7232 are far away from each other to form a flared structure, so that the transverse rib 103 can be smoothly clamped into the elastic clip groove 721.

[0085] Specifically, in this embodiment, the elastic clamping member 72 is integrally formed by using 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 arc mesh welding can adapt to inner arc steel bars 101 of different diameters.

[0087] In order to ensure the positioning accuracy of the inner arc steel bars 101 of different sizes, see Figure 3 , Figure 4 and Figure 8 In this embodiment, the arc mesh welding positioning mechanism further includes an inner arc steel bar arc edge adjustment component 4, and the inner arc steel bar arc edge adjustment component 4 includes a first driving member 42 and a first pushing member 41.

[0088] The first driving member 42 is fixedly disposed on the frame 1 .

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

[0090] Specifically, Figure 3 Taking the shown orientation 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, and 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 slidably matched with the first pusher 41 is provided on the frame 1, and the first guide groove 11 extends along the first set direction.

[0092] Optionally, in this embodiment, the first pusher 41 is a cylinder. A first slot for engaging with the arc edge 1011 is disposed on a side surface of the first pusher 41 .

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

[0094] The second driving member is fixedly arranged on the frame 1 .

[0095] The second pushing member 51 is arranged at the output end of the second driving member, and the second pushing member 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, Figure 3 Taking the shown position 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 edge 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 pushing member 51 pushes the inner arc steel bar 101 along the second set direction, a second guide groove 12 slidably matched with the second pushing member 51 is provided on the frame 1, and the second guide groove 12 extends along the second set direction.

[0099] Furthermore, in this embodiment, in order to enable the arc mesh welding positioning mechanism to adapt to the outer arc steel 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 steel bar 102 .

[0100] In order to prevent the outer arc steel bars 102 of different diameters from moving in their own radial direction after falling into the second positioning groove 311, in this embodiment, see Figure 3 The arc mesh welding positioning mechanism also includes an outer arc steel bar adjustment component 6, and the outer arc steel bar adjustment component 6 includes a third driving member and a third pushing member 61.

[0101] The third driving member is fixedly arranged on the frame 1 .

[0102] The third pushing member 61 is disposed at the output end of the third driving 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, Figure 3 Taking the illustrated position as an example, after 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 member is a cylinder. A third clamping groove that matches the outer arc steel bar 102 is provided on the side of the third pushing member 61 .

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

[0106] In this embodiment, the arrangement of the inner arc steel bar arc edge adjustment component 4, the inner arc steel bar folding edge adjustment component 5 and the outer arc steel bar adjustment component 6 can not only enable the arc mesh welding positioning mechanism to adapt to inner arc steel bars 101 of different diameters and outer arc steel bars 102 of different diameters, but also ensure that the contour dimensions of the arc mesh welded on the arc mesh welding positioning mechanism are consistent.

[0107] Optionally, in this embodiment, the number of the inner arc steel bar arc edge adjustment components 4 and the number of the outer arc steel bar adjustment components 6 are both multiple.

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

[0109] Further, after the arc mesh is welded, it is necessary to transfer the welded arc mesh away. In this embodiment, see Figure 4 and Figure 8, the positioning mechanism for arc-shaped mesh welding further includes an arc-shaped mesh pushing component 8, and the arc-shaped mesh pushing component 8 includes a fourth driving member 81 and a pushing member 82.

[0110] The fourth driving member 81 is fixedly arranged on the frame 1.

[0111] The pushing member 82 is arranged at the output end of the fourth driving member 81, and the pushing member 82 can push the welded arc-shaped mesh away from the positioning mechanism for arc-shaped mesh welding.

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

[0113] The pushing member 82 is in a "C" shape, including a connecting arm 821 and two lifting arms 822. The connecting arm 821 is connected to the output end of the fourth driving member 81, and the two lifting arms 822 are respectively fixedly connected to both ends of the connecting arm 821. The lifting arms 822 are perpendicularly arranged with the connecting arm 821. One of the lifting arms 822 can rise to abut against the outer arc steel bar 102, and the other lifting arm 822 can rise to abut against the arc edge 1011 of the inner arc steel bar 101.

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

[0115] Furthermore, through holes for the lifting arms 822 to pass through are arranged on the frame 1.

[0116] Optionally, in this embodiment, the number of the arc-shaped mesh pushing components 8 is several; it can be two or more than two, and can be set according to needs.

[0117] Exemplarily, in this embodiment, the using method of the positioning mechanism for arc-shaped mesh welding is as follows:

[0118] Place the inner arc steel bar 101 and the outer arc steel bar 102 in place, control the inner arc steel bar arc edge adjusting component 4, the inner arc steel bar edge folding adjusting component 5 and the outer arc steel bar adjusting component 6 to complete their actions, and place the multiple cross bars 103 in place one by one;
