Description

Technical Field

[0001] This utility model relates to the field of laser welding technology, and in particular to a laser welding head wire feeding structure that is easy to assemble and disassemble. Background Technology

[0002] In laser welding, the wire feeding structure plays a crucial role, precisely delivering the welding wire to the welding area to ensure weld quality. Traditional laser welding head wire feeding structures often suffer from inconvenient assembly and disassembly. When maintenance, wire type replacement, or welding process parameter adjustment is required, the complex assembly and disassembly process consumes a significant amount of time, reducing production efficiency. Moreover, during welding operations, due to the complex shape of the workpiece or the special welding position, the wire feeding structure is prone to collision with the workpiece. Once a collision occurs, the existing rigid connection method is highly susceptible to damage to the wire feeding structure and welding head, increasing equipment maintenance costs and affecting production schedule.

[0003] Therefore, the existing laser welding technology field needs further improvement. Utility Model Content

[0004] The purpose of this invention is to provide a laser welding head wire feeding structure that is easy to assemble and disassemble, aiming to solve the problems of difficult assembly and disassembly of existing wire feeding structures and their susceptibility to damage upon collision with the workpiece. This allows for convenient and rapid disassembly and installation of the wire feeding structure, while also featuring automatic detachment upon impact to protect itself and the welding head assembly.

[0005] To achieve the above objectives, the present invention adopts the following solution: a laser welding head wire feeding structure that is easy to assemble and disassemble, including a welding head assembly and a multi-position adjustment assembly. The multi-position adjustment assembly is provided with a wire feeding structure. A magnetic attraction assembly is provided between the multi-position adjustment assembly and the welding head assembly. The multi-position adjustment assembly is provided with a positioning hole. The welding head assembly is provided with a positioning shaft that can cooperate with the positioning hole. A ball-locking structure is provided between the positioning hole and the positioning shaft. An external elastic positioning assembly is provided between the outer wall of the multi-position adjustment assembly and the welding head assembly.

[0006] Furthermore, the multi-directional adjustment component includes a connecting base, on which a horizontal position adjustment component is provided, a vertical position adjustment component is provided, and an angle adjustment component is provided on the vertical position adjustment component.

[0007] Furthermore, the magnetic attraction component includes a positive magnet disposed on the welding head component, and the connector is provided with a negative magnet that can be connected to the positive magnet.

[0008] Furthermore, the ball clamping structure includes four positioning grooves disposed on the outer circumference of the positioning shaft, and four balls are evenly distributed on the inner circumference of the positioning hole, with each of the four balls being fitted into a corresponding positioning groove.

[0009] Furthermore, the external elastic positioning component includes four radial guide grooves disposed on one side wall of the welding head component. The four radial guide grooves are evenly distributed around the center line of the positioning shaft. An elastic clamping part is movably disposed in the radial guide groove. The outer wall of the connecting seat is provided with four slots that can respectively cooperate with the four elastic clamping parts. The elastic clamping part presses towards the corresponding slot.

[0010] In summary, the advantages of this utility model over the prior art are:

[0011] This invention addresses the shortcomings of existing laser welding technologies. Through its structural design, it offers the following advantages: Utilizing a magnetic component, based on the principle of attraction between positive and negative magnets, the multi-directional adjustment component can be initially connected to the welding head component during installation, eliminating the need for cumbersome bolt operations and simplifying the process significantly, saving installation time. The ball-load clamping structure and the external elastic positioning component further solidify the connection. During disassembly, overcoming the corresponding elastic force and the clamping force of the slot allows for easy separation of the components. The entire disassembly and assembly process requires no complex tools, effectively shortening equipment maintenance and debugging time and improving production efficiency. During welding, if the wire feeding structure approaches or collides with the workpiece, the impact force first acts on the multi-directional adjustment component. At this point, the external elastic positioning component plays a crucial role; the external force causes the elastic clamping part to disengage from the slot, and with the magnetic connection loosening, the multi-directional adjustment component quickly and automatically separates the wire feeding structure from the welding head component, preventing the impact force from being transmitted to the welding head component, effectively preventing equipment damage, reducing maintenance frequency and costs, and ensuring stable and continuous production.

[0016] 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.

[0017] Please see Figures 1-4 This utility model provides a convenient assembly and disassembly laser welding head wire feeding structure, including a welding head assembly 1 and a multi-position adjustment assembly 2. The multi-position adjustment assembly 2 is provided with a wire feeding structure 3. A magnetic suction assembly 4 is provided between the multi-position adjustment assembly 2 and the welding head assembly 1. The multi-position adjustment assembly 2 is provided with a positioning hole 5. The welding head assembly 1 is provided with a positioning shaft 6 that can cooperate with the positioning hole 5. A ball clamping structure 7 is provided between the positioning hole 5 and the positioning shaft 6. An external elastic positioning assembly 8 is provided between the outer wall of the multi-position adjustment assembly 2 and the welding head assembly 1.

[0018] First, hold the multi-directional adjustment component 2 and align the negative magnet 402 on the connector 201 with the positive magnet 401 on the welding head component 1. Slowly bring them closer. At this time, due to the magnetic attraction, the two will initially attract each other and initially determine their relative positions.

[0019] Next, align the positioning hole 5 on the multi-directional adjustment component 2 with the positioning shaft 6 on the welding head component 1, and gently press down. The positioning shaft 6 is inserted into the positioning hole 5. During the process, the ball 702 on the inner wall of the positioning hole 5 is squeezed. When the ball 702 corresponds to the positioning groove 701 on the outer circumference of the positioning shaft 6, the ball 702 is stuck into the positioning groove 701 under the action of elasticity, so as to achieve further fastening.

[0020] At the same time, the elastic clamping part 802 in the radial guide groove 801 on one side wall of the welding head assembly 1 is pressed tightly into the corresponding slot 803 on the outer wall of the connecting seat 201 under its own elastic restoring force, thus completing the installation of the entire wire feeding structure. At this time, the wire feeding structure is stably connected to the welding head assembly 1, and normal welding wire feeding operation can be performed.

[0021] When it is necessary to disassemble the wire feeding structure, such as for maintenance or to replace the welding wire, first pull the multi-directional adjustment component 2 outward to disengage the elastic clamping part 802 from the slot 803 and release the outer fastening force.

[0022] Then, apply an appropriate upward pulling force to overcome the clamping force between the ball 702 and the positioning groove 701, and pull the positioning shaft 6 out of the positioning hole 5. At this time, the multi-directional adjustment component 2 is still connected to the welding head component 1 under the attraction of the magnetic component, but it is in a separable state.

[0023] Finally, manually overcome the magnetic force between the positive magnet 401 and the negative magnet 402 to completely remove the multi-directional adjustment component 2 from the welding head component 1. The entire disassembly process is simple and quick, without the need for complicated tools.

[0024] During the welding process, if the wire feeding structure is about to collide with the workpiece due to improper operation or irregular workpiece shape, the external force generated by the collision will first act on the multi-directional adjustment component 2 and the wire feeding structure connected to it.

[0025] External force is transmitted to the external elastic positioning component through the connecting seat 201. When the external force reaches a certain level, the elastic clamping part 802 is squeezed, overcomes its own elastic deformation, and disengages from the slot 803. At the same time, due to the loose connection, the magnetic attraction force of the magnetic component can no longer maintain a tight connection. The multi-directional adjustment component 2 drives the wire feeding structure to automatically separate from the welding head assembly 1, avoiding further transmission of the collision force to the welding head assembly 1, effectively protecting the wire feeding structure and the welding head assembly, and reducing the risk of equipment damage. After the collision risk is eliminated, the wire feeding structure can be reconnected according to the above installation steps to continue the welding operation.

[0026] The multi-directional adjustment component 2 of this utility model includes a connecting base 201, a horizontal position adjustment component 202 is provided on the connecting base 201, a vertical position adjustment component 203 is provided on the horizontal position adjustment component 202, and an angle adjustment component 204 is provided on the vertical position adjustment component 203.

[0027] The magnetic attraction component 4 of this utility model includes a positive magnet 401 disposed on the welding head component 1, and a negative magnet 402 disposed on the connecting seat 201 that can be connected to the positive magnet 401.

[0028] The ball clamping structure 7 of this utility model includes four positioning grooves 701 disposed on the outer circumference of the positioning shaft 6, and four balls 702 are evenly distributed on the inner circumference of the positioning hole 5. The four balls 702 are respectively fitted into one of the corresponding positioning grooves 701.

[0029] The external elastic positioning component 8 of this utility model includes four radial guide grooves 801 disposed on one side wall of the welding head component 1. The four radial guide grooves 801 are evenly distributed around the center line of the positioning shaft 6. An elastic clamping part 802 is movably disposed in the radial guide groove 801. The outer wall of the connecting seat 201 is provided with four slots 803 that can respectively cooperate with the four elastic clamping parts 802. The elastic clamping part 802 is pressed towards the corresponding slot 803.
