[0003] The existing steel mesh welding device consists of a coil feeding rack, a steel bar straightening machine, a welding machine, a pulling assembly and an automatic mesh cutting machine. During the operation, the operator first manually inserts the straightened longitudinal steel bars into the preset feed hole for positioning and fixing. Subsequently, the transverse steel bars in the storage trough will automatically fall out according to the predetermined spacing, and are arranged at right angles to the longitudinal steel bars at a certain spacing. The intersection points are connected using resistance spot welding technology to form a complete steel mesh. The pulling assembly is used to pull the welded steel mesh forward, and the automatic mesh cutting machine will automatically cut the mesh according to the set length.

[0004] In actual engineering applications, in order to meet the strength requirements of steel meshes for different engineering projects, it is often necessary to use steel bars of different diameters for welding. However, due to the fixed size of the feed holes, it is difficult to effectively position the longitudinal steel bars of different diameters, resulting in the need to replace the feed holes of appropriate sizes for the longitudinal steel bars of different diameters, causing inconvenience in operation and reducing the welding efficiency of the steel mesh.

[0005] Therefore, in view of this, the existing structure and defects are studied and improved, and a steel mesh welding device is provided to achieve a more practical purpose. Utility Model Content

[0009] The positioning assembly includes a chuck body, which is placed on a U-shaped fixing block and fixedly connected to the U-shaped fixing block. An end of the chuck body close to the steel bar straightening machine is provided with three guide grooves in an array, and claws are slidably provided in the three guide grooves. The longitudinal steel bar is located between the three claws. A claw driving assembly is provided in the chuck body, and the claw driving assembly drives the claw to slide toward the center or outward in the guide groove.

[0010] Furthermore, a rear end cover is provided at one end of the chuck body away from the steel bar straightening machine, and the rear end cover is connected to the claw driving assembly through bolts.

[0011] Furthermore, the clamping claw driving assembly includes a large bevel gear in the chuck body, the end face of the large bevel gear close to the steel bar straightening machine is provided with a plane thread, the bottom of the clamping claw is provided with a slot meshing with the plane thread, one end of the large bevel gear is provided with three small bevel gears in an array, and the large bevel gear meshes with the three small bevel gears;

[0012] The center of the large bevel gear extends outward to form a sleeve portion, the rear end cover is connected to the sleeve portion through bolts, and the large-diameter end of the small bevel gear is rotatably penetrated on the side wall of the chuck body.

[0013] Furthermore, a square hole is provided in the large-diameter end of the small bevel gear, and a wrench can be inserted into one of the square holes on the side wall of the chuck body.

[0014] Furthermore, one end of the claw close to the center is arc-shaped.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] Through the arrangement of the chuck body, guide grooves, claws and claw driving assembly, the operator only needs to insert one end of the longitudinal steel bar in the steel bar straightening machine into the center hole of the chuck body. The chuck body is fixed on the connecting plate by a U-shaped fixing block. The three guide grooves distributed in an array on the chuck body provide a precise moving trajectory for the claws.

[0029] The positioning assembly includes a chuck body 4, which is firmly placed on and fixedly connected to a U-shaped fixing block 11, thereby ensuring the stability of the positioning assembly. The chuck body 4 is provided with three guide grooves 5 in an array at one end close to the steel bar straightening machine. The three guide grooves 5 are divided at 120° on the chuck body 4. Claws 6 are slidably arranged in the three guide grooves 5. The longitudinal steel bar 3 is located between the three claws 6. The three claws 6 can independently slide toward the center or outward along the guide grooves 5 to adapt to longitudinal steel bars 3 of different diameters.

[0030] A large bevel gear 8 is provided in the chuck body 4, and a flat thread 13 is provided at one end of the large bevel gear 8 close to the longitudinal steel bar 3, and a clamping groove 14 meshing with the flat thread 13 is provided at the bottom of the claw 6. Three small bevel gears 9 are arranged in an array at one end of the large bevel gear 8, and the three small bevel gears 9 are all meshed with the large bevel gear 8 to form a bevel gear transmission. The center of the large bevel gear 8 extends outward to form a sleeve portion 15, and a rear end cover 7 is provided at one end of the chuck body 4 away from the longitudinal steel bar 3. The rear end cover 7 is connected to the sleeve portion 15 by bolts, and the rear end cover 7 plays a role in protecting the large bevel gear 8 and the small bevel gear 9, so as to avoid impurities or sparks generated by welding during welding from damaging the large bevel gear 8 and the small bevel gear 9;

[0031] The large-diameter end of the small bevel gear 9 is rotatably penetrated on the side wall of the chuck body 4, and a square hole 10 is opened in the large-diameter end of the small bevel gear 9.

By manually turning the wrench, the wrench drives the small bevel gear 9 to rotate, that is, drives the large bevel gear 8 to rotate synchronously, so that the flat thread 13 on the end face drives the three claws 6 to slide along their respective guide grooves 5 toward the center, so that the inner walls of the three claws 6 and the longitudinal steel bars 3 are aligned. The outer peripheral wall of the welding machine body 1 is in contact with the outer peripheral wall, ensuring that the longitudinal steel bars 3 of different diameters can be inserted into the positioning component in an adaptable manner. The transverse steel bars in the storage trough in the welding machine body 1 will automatically drop according to the predetermined spacing, and cross the longitudinal steel bars 3 at a certain spacing and form a right angle. The intersection points are connected by resistance spot welding technology to form a complete steel mesh.
