Description

Technical Field

[0001] The utility model relates to the technical field of spot welding equipment, in particular to a mesh spot welding equipment. Background Art

[0002] The mesh (steel mesh) is a mesh structure formed by several steel bars interlaced horizontally and vertically and fixed by spot welding, which can be used as a protective net, etc. The current spot welding operation of the mesh is generally: the steel bars are first positioned and placed in an assembly platform (box), and a positioning groove that matches the steel bars is provided on the edge of the box. Then, the box with the steel bars positioned and placed is placed on the spot welding machine, and the box is manually moved so that each steel bar intersection is spot welded in turn. When all the steel bar intersections are spot welded, the mesh is obtained. The above operation method requires a high level of experience for the workers, and the spot welding machine (electrode welding) will collide instantly during spot welding, which may easily cause some steel bars to bounce, and then the problem of steel bar dislocation occurs, and it is necessary to pause and sort it out, which is relatively troublesome. In addition, because the positioning groove is set on the box, the specifications of the mesh that the box can adapt to are limited, such as the number and spacing of horizontal and vertical steel bars are difficult to adjust, such as the inability to use steel bars with larger diameters instead, etc., and the versatility is relatively poor, so that the factory needs to prepare more boxes, which increases the equipment cost and is inconvenient to store.

[0042] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] like Figures 1 to 10 As shown, the utility model discloses a mesh spot welding device, which includes: a controller 10, a steel bar assembly platform, a material preparation rack, a moving mechanism and a spot welding mechanism. The material preparation rack is used to place the steel bar assembly platform, and the moving mechanism cooperates with the spot welding mechanism to automatically spot weld the steel bars 80 on the steel bar assembly platform positioned on the moving mechanism.

[0044] The material preparation rack includes a frame body 21 and two baffles 22. The baffles 22 are fixedly arranged on the frame body 21. The two baffles 22 are parallel to each other and arranged at intervals. The spacing between the two baffles 22 is adapted to the width of the steel bar assembly platform. Two rows of first cylinders 23 are arranged in the length direction of the baffles 22. The first cylinders 23 and the baffles 22 in the upper row constitute the upper material preparation area, and the first cylinders 23 and the baffles 22 in the lower row constitute the lower material preparation area. Both the upper material preparation area and the lower material preparation area are used to place the steel bar assembly platform. By setting the first cylinders 23, the steel bar assembly platform can be pushed smoothly, which is conducive to reducing the load, and the setting of the baffles 22 can ensure the stability of the moving direction of the steel bar assembly platform.

[0045] The moving mechanism includes a three-axis moving platform and a positioning frame for positioning and placing the steel bar assembly platform. The three-axis moving platform is arranged near the material preparation frame. The three-axis moving platform includes a longitudinal moving module 31, a transverse moving module 32 and a lifting module. The longitudinal moving module 31 and the transverse moving module 32 both include a motor, a slide rail, a screw and a slide. The slide rail and the screw are parallel to each other. The slide is slidably connected to the slide rail, and the slide is threadedly connected to the screw. The motor drives the screw to rotate, and the motor is connected to the controller 10. The transverse moving module 32 is arranged on the slide corresponding to the longitudinal moving module 31. The longitudinal moving module 31 drives the transverse moving module 32 to move longitudinally. The transverse moving module 32 drives the lifting module to move transversely. The lifting module includes a plurality of lifting cylinders 33. The lifting cylinders 33 are connected to the controller 10. The seat of the lifting cylinder 33 is installed on the slide corresponding to the transverse moving module 32. The push rod of the lifting cylinder 33 is connected to the positioning frame. In addition, a number of support blocks 34 for supporting the positioning frame are provided on the slide corresponding to the lateral moving module 32. Under normal circumstances, the lifting cylinder 33 is in a retracted state, and the support blocks 34 support the positioning frame so that the positioning frame can be reliably supported during the spot welding process, thereby extending the service life of the lifting cylinder 33.

[0046] When the lifting cylinder 33 is retracted and the longitudinal moving module 31 and the transverse moving module 32 are restored to their initial state, the positioning frame faces the lower material preparation area, and the steel bar assembly platform located in the lower material preparation area can be pushed onto the positioning frame. When the lifting cylinder 33 is extended and the longitudinal moving module 31 and the transverse moving module 32 are restored to their initial state, the positioning frame faces the upper material preparation area, and the steel bar assembly platform located in the upper material preparation area can be pushed onto the positioning frame.

[0047] In order to ensure that the steel bar assembly platform smoothly transitions between the positioning frame and the material preparation frame, the positioning frame is designed as follows: the positioning frame includes a frame 35 and a stop assembly. A plurality of second cylinders 36 are sequentially arranged at intervals on both sides of the frame 35 along the length direction. The second cylinders 36 and the frame 35 form a positioning chute 55 with a one-way opening 56. The length and width of the positioning chute 55 are adapted to the steel bar assembly platform. The arrangement of the second cylinder 36 allows the steel bar assembly platform to be smoothly pushed into the positioning chute 55. The stop assembly is used to limit the steel bar assembly platform to ensure that the steel bar assembly platform is not displaced when the positioning frame moves, thereby ensuring that spot welding is carried out smoothly. The stop assembly is arranged on one side of the opening 56 of the positioning chute 55 and includes a stop cylinder 37 and a stop block 38. The stop cylinder 37 drives the stop block 38 to move, and the stop cylinder 37 is connected to the controller 10. The stop block 38 is provided with a chamfer 39 for avoiding being stuck with the steel bar assembly platform. Under normal conditions, the stop block 38 does not extend into the opening 56 of the positioning slot 55, and the steel bar assembly platform can smoothly enter and exit the positioning slot 55. When the stop cylinder 37 is actuated, the stop block 38 will extend into the opening 56 of the positioning slot 55, thereby blocking the steel bar assembly platform.

[0048] The spot welding mechanism is arranged near the three-axis mobile platform, and includes a first lifting assembly 41, a second lifting assembly 42 and an electrode welding machine. The electrode welding machine includes a machine platform, a first electrode column 43 and a second electrode column 44. The first electrode column 43 and the second electrode column 44 are both electrically connected to the machine platform, and the machine platform is connected to the controller 10. The first electrode column 43 is arranged opposite to the second electrode column 44, and the first electrode column 43 is placed above the three-axis mobile platform, and the second electrode column 44 is placed below the three-axis mobile platform. The first lifting assembly 41 drives the first electrode column 43 to move up and down, and the second lifting assembly 42 drives the second electrode column 44 to move up and down. The first lifting assembly 41 and the second lifting assembly 42 can use cylinders or hydraulic cylinders. The first lifting assembly 41 and the second lifting assembly 42 are both connected to the controller 10.

[0049] The steel bar assembly platform includes a frame 50, a longitudinal positioning assembly, and at least four sets of transverse positioning assemblies 70. The frame 50 is made of a square tube, which can be compatible with strength and weight. The inner cavity of the square tube is also conducive to hiding components, making the assembly platform more concise in appearance and not easy to interfere with external components. The middle area of ​​the frame 50 is a cavity 51, and the cavity 51 is set to prevent the assembly platform from interfering with the electrode welding.

[0050] The longitudinal positioning assembly includes at least two first positioning members 61 and at least two limiting members 62. In this case, three first positioning members 61 are provided and two limiting members 62 are provided. The first positioning member 61 is made of a hard thick plate. The length direction of the first positioning member 61 is horizontal. The first positioning member 61 is placed in the cavity 51. At least one support member 52 for supporting the first positioning member 61 is provided in the cavity 51. The support member 52 is preferably made of a steel plate. The support strength of the first positioning member 61 can be ensured by the support of the support member 52. In addition, in order to facilitate the installation of the first positioning member 61, a socket 63 corresponding to the support member 52 is provided on the first positioning member 61. The first positioning member 61 is plugged into the support member 52 through the socket 63.

[0051] The limiting member 62 is a hard long rod, one end of which is provided with an end cap 64, and the other end is threadedly connected with a second locking member 65, the limiting member 62 passes through all the first positioning members 61 and is locked with both sides of the frame 50, and the first positioning members 61 are provided with through holes that match the limiting member 62. Specifically, both sides of the frame 50 are provided with limiting holes 53 and avoidance holes 54 for avoiding the end cap 64 and the second locking member 65, and the limiting holes 53 and the avoidance holes 54 are coaxially arranged. The threaded end of the limiting member 62 (the end connected to the second locking member 65) first passes through the avoidance hole 54 and the limiting hole 53 on one side of the frame 50 in sequence, and then passes through the first positioning member 61 in sequence, and then passes through the limiting hole 53 on the other side of the frame 50, and then is screwed and tightened with the second locking member 65. The end cap 64 is limitedly matched with one of the limiting holes 53, and the second locking member 65 is limitedly matched with the other limiting hole 53, so that the first positioning member 61 can be limited. At this time, the end head, the threaded end and the second locking member 65 of the limiting member 62 are all built into the inner cavity of the square tube. The first positioning member 61 can slide on the limiting member 62 so that the first positioning member 61 can avoid the intersection node of the steel bar 80, and the first positioning member 61 and the support member 52 are plugged in without interfering with the sliding of the first positioning member 61 on the limiting member 62. Of course, if the strength of the limiting member 62 is sufficient, the support member 52 can also be omitted.

[0052] A plurality of positioning grooves 66 are arranged at intervals along the length direction of the first positioning member 61. The positioning grooves 66 on the three first positioning members 61 correspond to each other and are used to position and place the longitudinal steel bars 80. In this case, the width of the positioning grooves 66 decreases from the groove opening to the groove bottom. This arrangement allows the positioning grooves 66 to position steel bars 80 of different diameters and ensure that the steel bars 80 are placed stably.

[0053] Six sets of transverse positioning components 70 are equally divided into two groups and are respectively arranged at the two ends of the frame 50. The transverse positioning components 70 at the two ends of the frame 50 are arranged one by one to position the transverse steel bars 80. Specifically, the transverse positioning components 70 include a mounting seat 71, a sliding member 72, a first locking member 73 and a second positioning member 74. The mounting seat 71 is slidably connected to the frame 50. A slide groove 55 extending in the longitudinal direction is provided at both ends of the frame 50. Two sliding rods 75 are provided on the mounting seat 71. The sliding rods 75 are inserted into the slide groove 55 and slidably connected thereto. One end of one of the sliding rods 75 away from the mounting seat 71 is provided with a threaded section, and the threaded section is threadedly connected with a third locking member 76. By tightening the third locking member 76, the position of the mounting seat 71 can be locked. The third locking member 76 is placed in the inner cavity of the square tube. An opening 56 with an exposed threaded section and the third locking member 76 is provided on the frame 50. Preferably, the top surface of the square tube is hollowed out to form the opening 56.

[0054] The sliding member 72 slides up and down relative to the mounting seat 71, and the sliding member 72 penetrates the mounting seat 71. The second positioning member 74 is arranged at the upper end of the sliding member 72, and the first locking member 73 is threadedly connected with the lower end of the sliding member 72. The first locking member 73 can be limitedly matched with the bottom surface of the mounting seat 71, and the second positioning member 74 can be limitedly matched with the top surface of the mounting seat 71. A positioning hole 77 is arranged on the second positioning member 74, and the aperture of the positioning hole 77 is larger than the diameter of the steel bar 80 used for the conventional mesh to ensure that the positioning hole 77 can adapt to the steel bar 80 of different diameters, and the aperture of the positioning hole 77 is perpendicular to the length direction of the positioning groove 66. In addition, it is also required that the top surface of the mounting seat 71 is set lower than the bottom of the positioning groove 66.

[0055] Of course, in order to better stabilize the transverse steel bars 80, a transverse positioning assembly 70 may also be provided on some of the support members 52, and the connection method is the same as above and will not be repeated.

[0056] After the transverse positioning assembly 70 and the longitudinal positioning assembly are installed on the frame 50, the reinforcement bars 80 can be laid. When laying the reinforcement bars 80 on the utility model, first put the longitudinal reinforcement bars 80 into the positioning grooves 66 of the same longitudinal column. After all the longitudinal reinforcement bars 80 are placed, the transverse reinforcement bars 80 are passed through the positioning holes 77 of the same transverse column, and then the first locking member 73 is tightened. Before tightening the first locking member 73, it is possible to first check whether the first positioning member 61 will interfere with the intersection node of the reinforcement bars 80. If there is interference, it can be adjusted by moving the first positioning member 61. Of course, this step can also be performed before the reinforcement bars 80 are placed.

[0057] After the steel bar 80 is laid out on the steel bar assembly platform located in the upper material preparation area, the steel bar assembly platform is pushed into the positioning frame and locked by the stop assembly. The lifting cylinder 33 will retract. At this time, the controller 10 controls the longitudinal moving module 31 and the transverse moving module 32 to move in sequence according to the specifications of the mesh, so that the cross node of the steel bar 80 moves between the first electrode and the second electrode, and controls the first lifting assembly 41 and the second lifting assembly 42 to move synchronously and touch the cross node of the steel bar 80 at the same time to realize the spot welding operation. During the spot welding process, the steel bar 80 can be laid out on the steel bar assembly platform located in the lower material preparation area. After all the cross nodes of the steel bars 80 are spot welded, the longitudinal moving module 31 and the transverse moving module 32 are reset, the lifting cylinder 33 is extended, the stop block is retracted, the steel bar assembly platform in the positioning frame is pushed back to the upper material preparation area, and then the lifting cylinder 33 is retracted, and the steel bar assembly platform located in the lower material preparation area can be pushed into the positioning frame to start the next round of spot welding, and at this time, the steel bar assembly platform located in the upper material preparation area can re-arrange the steel bars 80, and so on, with high processing efficiency, low work intensity for workers, and quick to get started. The lifting cylinder 33 and the stop cylinder 37 can be controlled by manually operating the buttons on the controller 10, and in addition, the start of the spot welding operation can also be controlled by manually operating the buttons on the controller 10.

[0058] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by any technician familiar with the technical field within the technical scope disclosed in the present invention should be included in the protection scope of the present invention.
