Description

Technical Field

[0001] This utility model relates to the technical field of wire mesh welding positioning devices, and in particular to a multi-station wire mesh welding positioning fixture. Background Technology

[0002] In industrial production, wire mesh, as an important basic component, is widely used in various fields such as building protection, aquaculture fencing, filter materials, and automobile manufacturing. The welding quality and production efficiency of wire mesh directly affect product performance and enterprise economic benefits, and welding positioning fixtures are key equipment to ensure the welding accuracy and stability of wire mesh. To address this, patent CN220296286U discloses a positioning fixture for wire mesh welding, comprising a support plate, with symmetrical support mechanisms mounted on the top of the support plate. The tops of the two support mechanisms jointly support a welding table. A chip-extraction groove is formed in the center of the welding table, and multiple positioning mechanisms are mounted on the welding table. Each positioning mechanism is equipped with a pressing component. There are six positioning mechanisms in total: four are located on both sides of the chip-extraction groove, with two positioning mechanisms on each side, and the other two are installed on the other two sides of the chip-extraction groove. This invention has the advantages of being able to lay the wire mesh flat and straight, preventing it from warping; being able to press the positioned wire mesh onto the welding table with the pressing components, thus positioning it on the welding table; and being able to coordinate with the welding equipment after fixing, eliminating the need for manual welding. This improves the welding efficiency of the wire mesh by using welding equipment and avoids weld point cracking. The existing technical solutions mentioned above have the following drawbacks: although the mesh can be positioned, it can only be welded to a single station, which makes it inconvenient to perform multi-station synchronous operation on the mesh, thus affecting the efficiency of mesh positioning and welding processing. Utility Model Content

[0003] The purpose of this utility model is to provide a multi-station mesh welding positioning fixture to solve the defect of existing positioning fixtures that are inconvenient for multi-station synchronous operation of mesh.

[0004] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a multi-station mesh welding positioning fixture, including a processing table; The bottom of the processing table is equipped with a workstation conversion mechanism; The workstation conversion mechanism includes a frame plate fixedly installed at the bottom of the processing table. A drive motor is fixedly connected to the bottom of the frame plate. The output shaft of the drive motor is fixedly connected to a first rotating rod via a coupling. A first chuck is fixedly connected to the outer wall of the first rotating rod. A locking block is fixedly connected to the outer wall of the first chuck. A second chuck is movably connected to the outer wall of the first chuck. A second rotating rod is fixedly connected to the inner wall of the second chuck. A turntable is fixedly connected to the top of the second rotating rod.

[0005] Preferably, the first chuck has an clearance groove inside, and the second chuck has an active groove inside.

[0006] Preferably, the first chuck forms a rotating structure with the processing table via a first rotating rod, and the second chuck forms a rotating structure with the processing table via a second rotating rod, so that the first chuck can rotate along the processing table.

[0007] Preferably, the first chuck is movably connected to the second chuck via a clearance groove, and the chuck block forms a sliding structure with the second chuck via a movable groove, which can cause the first chuck to rotate and drive the second chuck to rotate.

[0008] Preferably, the movable slots are arranged in a ring around the central axis of the second chuck, and the turntable forms a rotating structure with the processing table through the second rotating rod, which can make the turntable rotate along the processing table to realize the change of work position.

[0009] Preferably, the processing table has a slotted design, and the turntable is located inside the processing table.

[0010] Preferably, a positioning mechanism is installed on the top of the turntable. The positioning mechanism includes a placement frame fixedly installed on the top of the turntable. The placement frame has a horizontal placement groove and a vertical placement groove inside. A horizontal baffle is fixedly connected to the outer wall of the placement frame. A side plate is fixedly connected to the outer wall of the placement frame. A threaded groove is opened inside the side plate. A threaded post is movably connected inside the threaded groove. A pressure plate is movably connected to one end of the threaded post. A guide rod is fixedly connected to the top of the pressure plate.

[0011] Preferably, the transverse placement grooves are perpendicular to the longitudinal placement grooves, and the depth of the transverse placement grooves is greater than that of the longitudinal placement grooves, which facilitates the placement of the crisscrossing wire mesh raw materials.

[0012] Preferably, the side plate is threadedly connected to the threaded post via a threaded groove, and the threaded post and the pressure plate form a rotating structure, which allows the threaded post to rotate and squeeze the pressure plate.

[0013] Preferably, the guide rod and the side plate form a sliding structure, and the guide rod is symmetrically arranged about the central axis of the pressure plate, so that the guide rod can slide along the side plate.

[0014] The multi-station wire mesh welding positioning fixture provided by this utility model has the following advantages: By setting up a processing table, a station conversion mechanism, and a turntable, the first chuck can be rotated by starting the drive motor. When the chuck block rotates to one side of the inner wall of the movable groove, it will slide along the movable groove, causing the second chuck to rotate 90°, which in turn causes the turntable fixedly connected to the top of the second rotating rod to rotate 90°, thus changing the station position at the top of the turntable. This facilitates multi-station synchronous operation of the mesh and further improves the efficiency of mesh welding. Furthermore, the clearance groove can prevent interference in the transmission between the first chuck and the second chuck, thus improving the stability of the rotary transmission. Furthermore, since the turntable is located in a slot inside the processing table, the stability of the turntable rotation adjustment can be improved. By using the positioning mechanism, the rotating threaded column can squeeze the pressure plate, which in turn pushes the longitudinal steel wire downward, thus facilitating the limiting of the wire mesh. Furthermore, the sliding action of the guide rod and side plate enhances the stability of the pressure plate pressing down, thereby improving the stability of the mesh positioning.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figures 1-5 The present invention provides a multi-station mesh welding positioning fixture, including a processing table 1.

[0019] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a workstation conversion mechanism 2 is installed at the bottom of the processing table 1. The workstation conversion mechanism 2 includes a frame plate 21 fixedly installed at the bottom of the processing table 1. A drive motor 22 is fixedly connected to the bottom of the frame plate 21. The output shaft of the drive motor 22 is fixedly connected to a first rotating rod 23 via a coupling. A first chuck 24 is fixedly connected to the outer wall of the first rotating rod 23. A locking block 26 is fixedly connected to the outer wall of the first chuck 24. A second chuck 27 is movably connected to the outer wall of the first chuck 24. A second rotating rod 29 is fixedly connected to the inner wall of the second chuck 27. A turntable 3 is fixedly connected to the top of the second rotating rod 29. The inner wall of the first chuck 24... The first chuck 24 is provided with a clearance groove 25, and the second chuck 27 is provided with a movable groove 28. The first chuck 24 is connected to the processing table 1 through the first rotating rod 23 to form a rotating structure. The second chuck 27 is connected to the processing table 1 through the second rotating rod 29 to form a rotating structure. The first chuck 24 is movably connected to the second chuck 27 through the clearance groove 25. The chuck block 26 is connected to the second chuck 27 through the movable groove 28 to form a sliding structure. The movable groove 28 is arranged in a ring around the central axis of the second chuck 27. The turntable 3 is connected to the processing table 1 through the second rotating rod 29 to form a rotating structure. The processing table 1 is a slotted design, and the turntable 3 is located inside the processing table 1.

[0020] By starting the drive motor 22, the first rotating rod 23 can be rotated, which in turn drives the first chuck 24 to rotate. When the chuck 26 rotates to one side of the inner wall of the movable groove 28, the chuck 26 will slide along the movable groove 28, which will drive the second chuck 27 to rotate along the processing table 1. Under the action of the clearance groove 25, interference can be prevented between the rotational transmission of the first chuck 24 and the second chuck 27. When the second chuck 27 rotates 90°, the chuck 26 can slide out of the movable groove 28, which will drive the turntable 3 fixedly connected to the top of the second rotating rod 29 to rotate 90°, so that the working position of the top of the turntable 3 changes. When the first working position is welding, the other working positions can stack the wire mesh in a crisscross pattern and can also pick up the welded wire mesh.

[0021] Reference Figure 1 and Figure 5 As shown, a positioning mechanism 4 is installed on the top of the turntable 3. The positioning mechanism 4 includes a placement frame 41 fixedly installed on the top of the turntable 3. The placement frame 41 has a horizontal placement groove 42 and a vertical placement groove 43 inside. A horizontal baffle 44 is fixedly connected to the outer wall of the placement frame 41. A side plate 45 is fixedly connected to the outer wall of the placement frame 41. A threaded groove 46 is opened inside the side plate 45. A threaded post 47 is movably connected inside the threaded groove 46. A pressure plate 48 is movably connected to one end of the threaded post 47. A guide rod 49 is fixedly connected to the top of the pressure plate 48. The horizontal placement groove 42 and the vertical placement groove 43 are perpendicularly distributed. The depth of the horizontal placement groove 42 is greater than that of the vertical placement groove 43. The side plate 45 is threadedly connected to the threaded post 47 through the threaded groove 46. The threaded post 47 and the pressure plate 48 form a rotating structure. The guide rod 49 and the side plate 45 form a sliding structure. The guide rod 49 is symmetrically arranged about the central axis of the pressure plate 48.

[0022] By placing the transverse steel wires for welding the mesh in the transverse placement groove 42 and blocking both ends of them with the transverse baffles 44, and placing the longitudinal steel wires in the longitudinal placement groove 43, so that they are staggered and pressed on top of the transverse steel wires, the threaded column 47 is rotated. Since the threaded column 47 is threadedly connected to the side plate 45 through the threaded groove 46, the threaded column 47 can squeeze the pressure plate 48, causing the guide rod 49 to slide along the side plate 45, driving the pressure plate 48 to press down on the longitudinal steel wires, so that the mesh steel wires are limited.

[0023] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
