Description

Technical Field

[0001] This utility model relates to the field of welding technology, specifically to an automatic wire feeding welding device. Background Technology

[0002] In modern industrial fields such as automobile manufacturing, electronics, and medical devices, welding is a core process for connecting metal parts. Traditional welding relies on manual wire feeding and operation, which has significant limitations.

[0003] Because welding wires have slight diameter tolerances and different materials have different hardness, existing non-adjustable wire feeding wheels cannot adjust the pressure and clamping force according to the actual situation of the wires: if the pressure is too low, the wire is prone to slipping, the wire feeding speed error is large, resulting in insufficient weld filling; if the pressure is too high, the wire will be squeezed and deformed, destroying the straightness of the wire and causing the welding position to shift. Therefore, we propose an automatic wire feeding welding device. Summary of the Invention

[0004] The purpose of this invention is to provide an automatic wire feeding and welding device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: an automatic wire feeding and welding device, comprising a worktable, support legs disposed at the bottom of the worktable, and further comprising: The wire feeding assembly includes a second bracket connected to the top of the workbench, a sliding plate slidably connected to the second bracket, a fixed seat connected to the bottom of the sliding plate, a rotating roller rotatably connected to the fixed seat, and a wire feeding wheel for feeding wires provided on the rotating roller; An adjustment assembly includes a sliding rod slidably connected to a second bracket, a drive plate rotatably connected to the top of the sliding rod, a support rod connected to the top of the second bracket, a rotating shaft rotatably connected to the top of the support rod, the rotating shaft being connected to the drive plate, and an electric push rod for pushing the drive plate being provided on the top of the second bracket, the output end of the electric push rod being connected to the drive plate.

[0006] Furthermore, a detection component is provided on the top of the workbench. The detection component includes a housing, and a pressure sensor for detecting pressure is provided inside the housing. The housing is threadedly connected to the workbench with bolts.

[0007] The above technical solution involves setting up a detection component to detect the pressure of the cable feed roller on the cable, and adjusting it in time when the pressure is too high.

[0008] Furthermore, the rotating roller is provided with a transmission assembly, which includes a pulley mounted on the rotating roller and a belt sleeved on the pulley.

[0009] The above technical solution involves setting up a transmission component to drive two wire feeding wheels to rotate synchronously in the same direction.

[0010] Furthermore, a welding assembly is provided on the workbench. The welding assembly includes a first bracket connected to the top of the workbench. A power supply box is provided on the top of the first bracket. A cable is connected to the power supply box, and a welding head is connected to the side of the cable away from the power supply box.

[0011] The above technical solution involves setting up welding components to melt and fuse the welding wire and the workpiece to be welded, forming a weld.

[0012] Furthermore, a clamping assembly is provided on the top of the workbench near the welding assembly. The clamping assembly includes a slide groove formed on the top of the workbench, a lead screw rotatably connected in the slide groove, a sliding block threaded onto the lead screw, and a clamping plate for clamping the workpiece connected to the sliding block.

[0013] The above technical solution involves using clamping components to clamp and fix the workpiece, preventing slippage during the welding process.

[0014] Furthermore, a first motor is installed inside the slide groove, the lead screw is connected to the output end of the first motor, and two sliding blocks are provided, with the two sliding blocks threaded onto the lead screw in opposite directions.

[0015] The above technical solution is adopted: by setting the first motor as the power source for the rotation of the lead screw, the two sliding blocks are driven to move in opposite directions in the slide groove.

[0016] Furthermore, a second motor is provided at the bottom of the sliding plate, the rotating roller is connected to the output end of the second motor, and a guide bar is provided at the top of the worktable.

[0017] The above technical solution is adopted by setting a second motor as the power source for the rotation of the rotating roller, and setting guide bars to limit the movement trajectory of the welding line.

[0018] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this invention, by setting an adjustment component, the height of the wire feeding wheel is finely adjusted to control the clamping force, avoiding slippage or excessive compression. This solves the problem that existing non-adjustable wire feeding wheels cannot adjust the pressure and clamping force according to the actual situation of the wire: if the pressure is too low, the wire is prone to slippage, the wire feeding speed error is large, resulting in insufficient weld filling; if the pressure is too high, it will squeeze the wire to deform, destroy the straightness of the wire, and thus cause the welding position to shift.

The transmission assembly 7 includes a pulley 71 provided on the rotating roller 55 and a belt 72 sleeved on the pulley 71. Specifically, for different welding wires, the height of the wire feeding wheel 53 is first adjusted. The electric push rod 65 is turned on to drive the drive plate 62 to rotate through the rotating shaft 64. During the rotation, the drive plate 62 will drive the sliding rod 61 to slide on the second bracket 51, thereby driving the sliding plate 52 at the bottom to slide. The sliding plate 52 drives the wire feeding wheel 53 at the bottom to move. Then, the second motor is turned on to drive the rotating roller 55 to rotate. The rotating roller 55 drives the wire feeding wheel 53 to rotate. When the rotating roller 55 rotates, it will drive the pulley 71 and belt 72 to transmit power, so that the two wire feeding wheels 53 rotate synchronously to transport the welding wire.

[0026] Furthermore, such as Figure 3 As shown: A welding assembly 3 is provided on the workbench 1. The welding assembly 3 includes a first bracket 31 connected to the top of the workbench 1. A power supply box 32 is provided on the top of the first bracket 31. A cable 34 is connected to the power supply box 32. A welding head 33 is connected to the side of the cable 34 away from the power supply box 32. When the power supply box 32 is turned on, power is transmitted to the welding head 33 through the cable 34 for welding. The above solutions also include the need to maintain the stability of the workpiece during the welding process, such as... Figure 3 As shown: A clamping assembly 4 is provided on the top side of the workbench 1 near the welding assembly 3. The clamping assembly 4 includes a slide groove 41 opened on the top of the workbench 1. A lead screw 43 is rotatably connected in the slide groove 41. A sliding block 42 is threadedly connected to the lead screw 43. A clamping plate 44 for clamping the workpiece is connected to the sliding block 42. A first motor is provided in the slide groove 41. The lead screw 43 is connected to the output end of the first motor. There are two sliding blocks 42. The two sliding blocks 42 are threaded in opposite directions on the lead screw 43. When the first motor is turned on, it drives the lead screw 43 to rotate in the slide groove 41. The lead screw 43 drives the two sliding blocks 42 to move in opposite directions in the slide groove 41. Then, it drives the clamping plate 44 to clamp and fix the workpiece. The above solution also requires real-time monitoring of the pressure on the welding wire from the wire feed roller 53. Figure 1As shown: A detection component 8 is provided on the top of the workbench 1. The detection component 8 includes a housing 81. A pressure sensor for detecting pressure is provided inside the housing 81. The housing 81 is threadedly connected to the workbench 1 by a bolt 82. By setting the detection component 8, the pressure of the wire feeding wheel 53 on the cable is detected, and the pressure is adjusted in time when it is too high. The working principle provided by this utility model is as follows: Figures 1-4 As shown: First, the welding wire is placed on the top of the workbench 1 between the two guide bars 9. Then, the workpiece is placed on the other side of the top of the workbench 1. The first motor is turned on, driving the lead screw 43 to rotate in the slide groove 41. The lead screw 43 drives the two sliding blocks 42 to move in opposite directions in the slide groove 41, which then drives the clamping plate 44 to clamp and fix the workpiece. Then, for different welding wires, the height of the wire feeding wheel 53 is adjusted. The electric push rod 65 is turned on, driving the drive plate 62 to rotate through the rotating shaft 64. The drive plate 62 rotates... During the process, the sliding rod 61 will slide on the second bracket 51, thereby causing the sliding plate 52 at the bottom to slide. The sliding plate 52 will drive the wire feeding wheel 53 at the bottom to move. Then, the second motor will be turned on to drive the rotating roller 55 to rotate. The rotating roller 55 will drive the wire feeding wheel 53 to rotate. When the rotating roller 55 rotates, it will drive the pulley 71 and belt 72 to drive the transmission, so that the two wire feeding wheels 53 rotate synchronously to transport the welding wire. Finally, the power box 32 will be turned on to transmit power to the welding head 33 through the cable 34 for welding.
