[0002] The forklift steel ring belongs to a kind of wheel steel ring, which is mainly used in forklift wheels. The appearance of this kind of steel ring does not need to be beautiful, only the stiffness needs to meet the requirements. Therefore, the production is relatively simple compared with car steel rings. When the existing forklift steel rings are produced, generally, the steel coil is first cut into strips, and then the strip-shaped steel belt is wound into a cylindrical shape by a winding machine. Then, the two ends of the cylinder are welded, and then the pre-made spoke plate is welded and fixed inside the cylinder, thus forming a steel ring blank. Then, the steel ring blank is placed on a stamping machine to stamp and form both ends of it.

[0003] At present, during the production process of steel rings, a welding device is needed to perform welding work on the steel rings. However, most of the existing welding devices do not have the function of automatically adjusting the welding position. Due to the different sizes of steel rings, when the steel rings are fixed and welded, workers need to manually adjust the welding position of the welding torch according to the size of the steel rings before welding work can be carried out, resulting in a low degree of automation of the device and reducing the welding efficiency of the steel rings.

[0004] Therefore, it is necessary to provide an automatic welding device for steel ring production to solve the above technical problems. Content of the Utility Model

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0028] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0029] Referring to Figures 1-4 , an automatic welding device for steel ring production provided by the present invention includes a base 1. Two support frames 2 and an electric control box 3 are fixedly connected to the top of the base 1. A rotating ring 4 is rotatably connected between the opposite sides of the two support frames 2. Two welding assemblies are arranged inside the rotating ring 4. A docking groove 5 is opened on the top of the base 1. Two sliders 6 are slidably connected inside the docking groove 5. A support plate 7 is fixedly connected to the tops of the two sliders 6. A clamping assembly and an alignment assembly are arranged on the support plate 7. Touch switches 8 and mounting blocks 9 are respectively arranged on both sides of the support plate 7. A bidirectional electric telescopic rod 10 is fixedly installed on the mounting block 9. A displacement sensor 11 is fixedly installed on one side of the mounting block 9. One of the telescopic ends of the bidirectional electric telescopic rod 10 is fixedly connected to a positioning plate 12. A rotating assembly and a driving assembly are arranged on the base 1. Through the settings of structures such as the base 1, the electric control box 3, the rotating ring 4, the displacement sensor 11, the welding mechanism 14, and the clamping plate 16, the moving distance for clamping steel rings of different sizes can be adjusted according to the movement of the clamping plate 16. Under the cooperative action of the electric control box 3, the telescopic length of the telescopic end of the electric push rod 13 can be automatically adjusted, so that the welding position of the steel ring by the welding mechanism 14 can be automatically adjusted, avoiding the problem that when the steel ring is fixed and welded, workers need to manually adjust the welding position of the welding torch according to the size of the steel ring before welding. The degree of automation is relatively high, and the welding efficiency of the steel ring is improved.

[0030] The welding assembly includes an electric push rod 13. The electric push rod 13 is fixedly installed on the rotating ring 4. The telescopic end of the electric push rod 13 is fixedly connected to a welding mechanism 14. The welding part of the welding mechanism 14 and the arc center of the clamping plate 16 are located on the same horizontal plane, so that the moving distance of the clamping plate 16 when clamping the steel ring is the same as the distance that the welding mechanism 14 can move for welding after moving. And through the setting of the two welding mechanisms 14, the welding efficiency can be improved.

[0031] The clamping assembly includes two first avoidance grooves 15 and two clamping plates 16. The two first avoidance grooves 15 are both formed in the support plate 7. The two clamping plates 16 are respectively slidably connected inside the two first avoidance grooves 15. The two clamping plates 16 are respectively fixedly connected to both ends of the bidirectional electric telescopic rod 10. The overlapping part where the two clamping plates 16 move relatively is at the same level as the circle of the rotating ring 4. The clamping plates 16 are arc-shaped, and second avoidance grooves 17 are formed in the clamping plates 16.

[0032] The alignment assembly includes two limiting rods 18. The two limiting rods 18 are both movably connected to the support plate 7. Springs 19 are sleeved on the outer surfaces of the two limiting rods 18. One end of each of the two limiting rods 18 is fixedly connected to a pressing plate 20. The pressing plate 20 is slidably connected to the two second avoidance grooves 17. The lengths of both ends of the pressing plate 20 are longer than the protruding length at the center, and the extended distance is the same as the horizontal diameter of the touch switch 8, so that while both ends of the pressing plate 20 are in contact with the support plate 7, the protrusion at the center is in contact with the touch switch 8.

[0033] The rotating assembly includes a first motor 21 and a toothed ring 22. The first motor 21 is fixedly installed on the top of the base 1. The first motor 21 is a stepper motor and can adjust the rotation speed of its output end. The output end of the first motor 21 is fixedly connected to a gear 23. The toothed ring 22 is fixedly sleeved on the outer surface of the rotating ring 4. The gear 23 meshes with the toothed ring 22. By starting the first motor 21, the gear 23 is driven to rotate. The gear 23 drives the toothed ring 22 meshing with it to rotate. The toothed ring 22 drives the rotating ring 4, the two electric push rods 13 and the two welding mechanisms 14 to rotate synchronously, so that the two welding mechanisms 14 can simultaneously perform the rotating welding work on the steel ring, further improving the welding efficiency.

[0034] The driving assembly includes a second motor 24 and a bidirectional threaded rod 25. The second motor 24 is fixedly installed on one side of the base 1. The bidirectional threaded rod 25 is rotatably connected between the two inner walls of the docking groove 5. The bidirectional threaded rod 25 is threadedly connected to the two sliders 6. The second motor 24 is fixedly connected to one end of the bidirectional threaded rod 25.

[0035] Working principle: During operation, place the steel ring to be welded on one of the lower clamping plates 16. By activating the bidirectional electric telescopic rod 10, its bidirectional telescopic ends can contract synchronously. Under the combined action of the first avoidance groove 15 and the second avoidance groove 17, the two clamping plates 16 move relative to each other, enabling the steel ring to be fixedly clamped. At the same time, during the relative movement of the two clamping plates 16, the positioning plate 12 can be mobilized to move synchronously. Under the detection of the displacement sensor 11, the moving distance of the clamping plate 16 can be detected, and its data is transmitted to the electric control box 3. Then, after both pairs of clamping plates 16 clamp the corresponding steel rings, the motor two 24 can be activated to drive the bidirectional threaded rod 25 to rotate. Under the limiting and matching action of the docking groove 5, the two sliders 6 can drive the corresponding support plates 7, bidirectional electric telescopic rods 10, extrusion plates 20, clamping plates 16 and other structures to move relatively synchronously, reducing the distance between the two clamped steel rings. Until the two steel rings are in contact, the distance between the two clamping plates 16 can be increased. When not firmly clamping the steel ring, under the action of the motor two 24 and the bidirectional threaded rod 25, the two steel rings continue to move, causing the spring 19 to be compressed and the limiting rod 18 to move until the extrusion plate 20 abuts against the corresponding support plate 7 and the touch switch 8, and then the bidirectional electric telescopic rod 10 can be activated again to firmly clamp and fix the steel ring;

[0036] When the steel ring is firmly clamped and fixed and the touch switch 8 is touched, after the touch switch 8 transmits a signal to the electric control box 3, the electric control box 3 activates the two electric push rods 13, the welding mechanism 14 and the motor one 21. After the two electric push rods 13 are activated, the electric control box 3 automatically controls the moving distance of its telescopic end to drive the welding mechanism 14 according to the moving distance transmitted by the displacement sensor 11, so that the moving distance of the welding mechanism 14 is adapted to the moving distance of the clamping plate 16. Then the activated welding mechanism 14 can perform the welding work on the connection. When the motor one 21 is activated, it drives the gear 23 to rotate, and the gear 23 drives the engaged toothed ring 22 to rotate. The toothed ring 22 drives the rotating ring 4, the two electric push rods 13 and the two welding mechanisms 14 to rotate synchronously, enabling the circumferential rotation welding work of the steel ring.

[0037] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
