Description
Technical Field
[0001] This utility model relates to the field of welding robot technology, specifically to a wire feeding mechanism for a welding robot. Background Technology
[0002] Welding robots are industrial robots specifically designed for welding operations. They can replace skilled welding workers and improve welding production efficiency. They typically consist of a robot body and a computer control system, and are versatile, reprogrammable, and adaptable to different welding needs.
[0003] The wire feeding mechanism of a welding robot is a device used to transport welding wire in welding equipment. Its main functions include stabilizing welding quality, improving work efficiency, and controlling costs. The wire feeding mechanism delivers welding material to the welding torch through a wire feeding hose, ensuring that the welding torch correctly locates the weld seam and automatically fills the weld seam, thereby guaranteeing welding quality. In addition, the wire feeding mechanism can also automatically feed wire according to welding instructions, reducing system response time and improving work efficiency.
[0004] The wire feeding mechanism of a conventional welding robot has a relatively fixed structure. It needs to be set up with a wire feeding structure that matches the structure of the welding robot, which makes the wire feeding structure less adaptable. At the same time, it is difficult to make flexible adjustments to the structure itself to ensure structural compatibility.
[0005] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and proposed a wire feeding mechanism for a welding robot. Utility Model Content
[0006] The purpose of this invention is to provide a wire feeding mechanism for a welding robot to solve the problems mentioned in the background art.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a wire feeding mechanism for a welding robot, comprising a feeding frame assembly and an adjusting frame assembly. The adjusting frame assembly is connected to the bottom middle of the feeding frame assembly, and a movable frame assembly is vertically installed on the top section of the adjusting frame assembly. An auxiliary frame assembly is connected to the bottom middle of the adjusting frame assembly. The adjusting frame assembly includes a tensioning guide wheel, a movable seat, a first adjusting screw, a fixed seat, and a second adjusting screw. Movable seats are installed on both the left and right sides of the tensioning guide wheel, and the first adjusting screw is vertically installed in the middle of the movable seat. A fixed seat is installed on the top of the first adjusting screw, and a second adjusting screw is horizontally installed on one side of the fixed seat.
[0008] Furthermore, the material feeding frame assembly includes an electric feeding roller, support arms, damping shafts, and fixed angle plates. Support arms are vertically installed on the left and right sides of the electric feeding roller, and damping shafts are installed at the bottom of the support arms. Fixed angle plates are symmetrically installed on the sides of the support arms.
[0009] Furthermore, the support arm and the fixed angle plate are integrally formed, and the end of the damping shaft away from the support arm is connected to the side of the fixed base.
[0010] Furthermore, the movable seat is threadedly connected to the first adjusting screw, and the second adjusting screw and the first adjusting screw are arranged opposite each other in a right-angled triangular structure.
[0011] Furthermore, the movable frame assembly includes auxiliary guide wheels, adjusting seats, a stabilizing frame, and adjusting wheels. Adjusting seats are installed on both the left and right sides of the auxiliary guide wheels, and a stabilizing frame is vertically installed on the top of the adjusting seats. Adjusting wheels are symmetrically installed on the middle section of the stabilizing frame.
[0012] Furthermore, the adjusting seat and the second adjusting screw are connected by a thread, and the adjusting seat and the stabilizer are connected by a weld.
[0013] Furthermore, the auxiliary frame assembly includes a rotating frame, a wire feeding hose, a support frame, and a connecting shaft. The wire feeding hose is vertically installed through the middle of the rotating frame, and support frames are installed on both the left and right sides of the rotating frame. A connecting shaft is installed on the top of the support frame.
[0014] Furthermore, the top of the connecting shaft is connected to the bottom of the adjusting seat, and the wire feeding hose is movably installed in the middle of the rotating frame.
[0015] This utility model provides a wire feeding mechanism for a welding robot, which has the following advantages:
[0016] 1. This utility model combines a material conveying frame assembly and an adjusting frame assembly. The damping shaft allows for rotational adjustment between the two assemblies, enabling them to be folded and adjusted within a certain angle range. The rotating frame connected to the support frame also possesses rotational adjustability, allowing the wire feeding hose to be folded and adjusted within a certain angle range. Furthermore, the wire feeding hose itself has a certain degree of structural bending adjustability due to its structural characteristics. Utilizing this structure, the entire device possesses dual-stage structural bending adjustability, allowing for structural adjustments as needed to adapt to the welding robot's welding arm. This ensures the device's structural flexibility and the accuracy of wire feeding, thereby guaranteeing the effectiveness of the welding process.
[0017] 2. This utility model utilizes a combination of an adjusting frame assembly and a movable frame assembly. By turning the first adjusting screw, the tensioning guide wheel connected to it via a movable seat can move up and down along the surface of the first adjusting screw. By turning the second adjusting screw, the auxiliary guide wheel connected to it via an adjusting seat can move back and forth along the surface of the second adjusting screw. Simultaneously, both sets of adjusting wheels can move up and down along the surface of the stabilizing frame for adjustment. This allows for adjustment in conjunction with the conveyed welding wire. The coordinated use of the above structure provides good tension adjustment for the conveyed welding wire, ensuring its stability during conveying. Furthermore, the adjusting wheels clamp and convey the welding wire, ensuring dual-stage tension adjustment in conjunction with the tensioning guide wheel and auxiliary guide wheel. This provides maximum flexibility for the device structure, allowing for adjustments to meet different setup requirements. Attached Figure Description

[0024] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.
[0025] like Figures 1 to 5 As shown, a wire feeding mechanism for a welding robot includes a feeding frame assembly 1 and an adjusting frame assembly 2. The adjusting frame assembly 2 is connected to the bottom center of the feeding frame assembly 1, and a movable frame assembly 3 is vertically installed on the top section of the adjusting frame assembly 2. An auxiliary frame assembly 4 is connected to the bottom center of the adjusting frame assembly 2. The adjusting frame assembly 2 includes a tensioning guide wheel 201, a movable seat 202, a first adjusting screw 203, a fixed seat 204, and a second adjusting screw 205. Movable seats 202 are installed on both the left and right sides of the tensioning guide wheel 201, and the first adjusting screw 203 is vertically installed in the middle of the movable seat 202. The fixed seat 204 is installed on the top of the first adjusting screw 203, and the second adjusting screw 205 is horizontally installed on one side of the fixed seat 204. The movable seat 202 and the first adjusting screw 203 are threadedly connected, and the second adjusting screw 205 and the first adjusting screw 203 form a right-angled triangular structure. The movable frame assembly 3 includes an auxiliary guide wheel 301, an adjusting seat 302, a stabilizing frame 303, and an adjusting wheel 304. Adjusting seats 302 are installed on both the left and right sides of the auxiliary guide wheel 301, and a stabilizing frame 303 is vertically installed on the top of the adjusting seat 302. Adjusting wheels 304 are symmetrically installed on the middle section of the stabilizing frame 303. The adjusting seat 302 and the second adjusting screw 205 are threaded together, and the adjusting seat 302 and the stabilizing frame 303 are welded together. The damping shaft 103 is used to connect the entire material conveying frame assembly 1 and the adjusting frame assembly 2, allowing them to be rotated and adjusted within a certain angle range. The rotating frame 401, which is connected to the support frame 403, also has rotational adjustment, allowing the wire feeding hose 402 to be adjusted appropriately within a certain angle range.
[0026] like Figures 1 to 5As shown, the feeding frame assembly 1 includes an electric feeding roller 101, support arms 102, damping shafts 103, and fixed angle plates 104. Support arms 102 are vertically installed on the left and right sides of the electric feeding roller 101, and damping shafts 103 are installed at the bottom of the support arms 102. Fixed angle plates 104 are symmetrically installed on the sides of the support arms 102. The support arms 102 and fixed angle plates 104 are integrated into one structure. The end of the damping shaft 103 away from the support arm 102 is connected to the side of the fixed base 204. The auxiliary frame assembly 4 includes a rotating frame 401, a wire feeding hose 402, a support frame 403, and a connecting shaft 404. The wire feeding hose 402 is vertically installed through the middle of the rotating frame 401, and fixed angle plates 104 are installed on both the left and right sides of the rotating frame 401. There is a support frame 403, and a connecting shaft 404 is installed on the top of the support frame 403. The top of the connecting shaft 404 is connected to the bottom of the adjusting seat 302, and the wire feeding hose 402 is movably installed in the middle of the rotating frame 401. By turning the first adjusting screw 203, the tensioning guide wheel 201 connected to it via the movable seat 202 can move up and down along the surface of the first adjusting screw 203. By turning the second adjusting screw 205, the auxiliary guide wheel 301 connected to it via the adjusting seat 302 can move back and forth along the surface of the second adjusting screw 205. At the same time, the two sets of adjusting wheels 304 can move up and down along the surface of the stabilizing frame 303 to adjust, thereby adjusting in coordination with the feeding of welding wire.
[0027] In summary, as Figures 1 to 5 As shown, the wire feeding mechanism of the welding robot first winds one end of the welding wire wound on the surface of the electric feeding roller 101 in a reverse "S" shape onto the surface of the two sets of adjusting wheels 304 on the stabilizer 303. At the same time, the adjusting wheels 304 are adjusted appropriately according to the diameter of the welding wire, and the welding wire is rolled and clamped to ensure the stable delivery of the subsequent welding wire.
[0028] Then, continue to wind one end of the welding wire in the same reverse "S" shape around the surfaces of the auxiliary guide wheel 301 and the tensioning guide wheel 201, and finally insert it into the inside of the wire feeding hose 402. During this process, the first adjusting screw 203 and the second adjusting screw 205 can be turned respectively, so that the tensioning guide wheel 201 connected to the first adjusting screw 203 via the movable seat 202, and the auxiliary guide wheel 301 connected to the second adjusting screw 205 via the adjusting seat 302, can be adjusted and moved along the surfaces of the first adjusting screw 203 and the second adjusting screw 205 respectively, and the welding wire can be tensioned.
[0029] Subsequently, based on the structure of the welding arm side of the welding robot, the entire device can be fixed to the surface of the welding arm of the welding robot using the fixing angle plate 104 on the side of the support arm 102. At the same time, the damping shaft 103 between the support arm 102 and the fixed seat 204 is used to bend and adjust the material feed frame group 1 and the adjustment frame group 2. Meanwhile, the structural mobility between the rotating frame 401 and the support frame 403, combined with the bending and adjustment of the wire feeding hose 402 itself, is used to appropriately adjust the orientation of the wire feeding hose 402, thereby ensuring accurate wire feeding operation for the welding robot.
