Description

Technical Field

[0001] This utility model relates to a welding wire feeding mechanism, belonging to the technical field of welding equipment. Background Technology

[0002] In modern industrial production, welding is an important joining process, widely used in joining metal materials. To improve welding quality and efficiency, precise wire feeding is one of the key factors. The welding wire is fed into the welding area through a guide channel, and the stability and guidance of the welding wire directly affect the continuity of the welding process and the welding quality. Traditional wire feeding mechanisms are far from the equipment and require constant manual adjustment, which can cause the welding wire to jam, bend, or be fed irregularly during the welding process, thus affecting the welding effect and production efficiency. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide a welding wire feeding mechanism that can provide stable welding wire guidance, ensure smooth feeding of welding wire, thereby improving welding quality and production efficiency.

[0004] To solve the above-mentioned technical problems, the technical solution of this utility model is: a welding wire feeding mechanism, comprising:

[0005] Mounting base;

[0006] A movable support plate is mounted on the mounting base, and a sliding seat is slidably mounted on the movable support plate;

[0007] A guide assembly, comprising a guide base and a guide gun, wherein the guide base is mounted on the sliding seat, and the guide gun comprises a fixed body and a plurality of elastic plates, wherein the plurality of elastic plates are circumferentially mounted around the front end of the fixed body, and the plurality of elastic plates together form a guide channel for the welding wire to pass through.

[0008] A stabilizing assembly, comprising a stabilizing base and a stabilizing clamp, wherein the stabilizing base is mounted on the sliding seat and the stabilizing clamp is mounted on the stabilizing base and the stabilizing clamp is adapted to clamp a welding wire passing through the guide channel.

[0009] Furthermore, to improve the flexibility of feeding, the sliding seat is slidably fitted onto the movable support plate via at least one guide rail slider pair;

[0010] The guide rail slider pair includes:

[0011] Guide rails mounted on the movable support plate;

[0012] A slider mounted on the bottom of the sliding seat.

[0013] Furthermore, in order to prevent the welding wire from shifting during the feeding process, the stabilizing clamp includes a clamp base and two clamping blocks, and the clamp base is mounted on the stabilizing base;

[0014] Two clamping blocks are disposed opposite to each other on the clamping platform, wherein one clamping block is fixedly installed on the clamping platform and the other clamping block is slidably installed on the clamping platform;

[0015] The two clamping blocks together form a clamping hole, which is coaxially arranged with the guide channel and is adapted to clamp the welding wire passing through the guide channel.

[0016] Furthermore, the stabilizing clamp also includes a locking bracket and a locking screw. The locking bracket is mounted on the clamp base, and the locking screw is mounted on the clamp base. The locking screw is connected to the clamping block that slides on the clamp base.

[0017] Furthermore, both clamping blocks are provided with V-shaped grooves.

[0018] Furthermore, in order to accommodate the diameter of the welding wire, the outer surface of the elastic sheet is provided with an external thread, and a tightening sleeve is provided on a plurality of elastic sheets. The tightening sleeve is provided with an internal thread, and the external thread is adapted to the internal thread. The tightening sleeve is adapted to compress the plurality of elastic sheets toward the center of the fixed body by tightening the threads, thereby reducing the diameter of the guide channel formed by the encirclement.

[0019] Furthermore, to improve efficiency, a welding wire feeding mechanism also includes a sliding drive assembly, which includes a drive bracket and a drive cylinder. The drive bracket is mounted on the mounting base, and the drive cylinder is mounted on the drive bracket. The movable end of the drive cylinder is connected to the guide base.

[0020] After adopting the above technical solution, this utility model has the following beneficial effects:

[0021] In this utility model, the tightening sleeve at the front end of the guide gun is loosened, the locking screw of the stabilizing clamp is released, and the sliding clamping block is moved to form a sufficiently large gap. The welding wire is then inserted from the fixed body at the rear end of the guide gun and passes through the guide channel formed by the elastic sheet and the clamping hole formed by the V-groove of the two clamping blocks of the stabilizing clamp in sequence.

[0022] The internal thread of the tightened sleeve engages with the external thread of the elastic plate. The conical surface inside the sleeve presses against the elastic plate, causing it to contract evenly toward the center until the diameter of the guide channel formed by the tightening is slightly greater than or equal to the diameter of the welding wire, providing a moderate and adjustable constraint force for the welding wire.

[0023] Tighten the locking screw of the stabilizing clamp to push the sliding clamping block to move towards the fixed clamping block, and use the V-groove to firmly and accurately clamp the welding wire, ensuring that the clamping hole is coaxial with the guide channel.

[0024] As needed, the guide base connected to it is moved by the drive cylinder, which in turn drives the entire sliding seat (including the guide assembly and the stabilizing assembly) to slide smoothly along the guide rail on the movable support plate to a new predetermined position, so that the outlet of the stabilizing clamp is as close as possible to the feeding point.

[0035] The stabilizing assembly includes a stabilizing base 41 and a stabilizing clamp. The stabilizing base 41 is mounted on a sliding seat 21, and the stabilizing clamp is mounted on the stabilizing base 41. The stabilizing clamp is adapted to hold the welding wire passing through the guide channel 331.

[0037] The guide rail slider pair includes:

[0038] Guide rail 22 is installed on movable support plate 2;

[0039] Slider 211 is installed at the bottom of sliding seat 21.

[0040] In this embodiment, the movable support plate 2 is provided with limiting blocks at both ends to restrict the movement of the slider 211.

[0041] Specifically, such as Figure 1-5 As shown, the stabilizing platform includes a platform base 42 and two clamping blocks 43, with the platform base 42 mounted on the stabilizing base 41.

[0042] Two clamping blocks 43 are arranged opposite to each other on the clamping platform 42. One clamping block 43 is fixedly installed on the clamping platform 42, and the other clamping block 43 is slidably installed on the clamping platform 42.

[0043] Two clamping blocks 43 together form a clamping hole 431. The clamping hole 431 is coaxially arranged with the guide channel 331. The clamping hole 431 is suitable for clamping the welding wire passing through the guide channel 331.

[0044] Specifically, such as Figure 1-5 As shown, the stabilizing clamp also includes a locking bracket 44 and a locking screw 45. The locking bracket 44 is mounted on the clamp base 42, and the locking screw 45 is mounted on the clamp base 42. The locking screw 45 is connected to the clamping block 43 that slides on the clamp base 42.

[0045] Specifically, such as Figure 1-5 As shown, both clamping blocks 43 are provided with V-shaped grooves 432.

[0046] Specifically, such as Figure 1-5 As shown, the outer surface of the elastic sheet 33 is provided with an external thread, and a tightening sleeve 332 is provided on multiple elastic sheets 33. The tightening sleeve 332 is provided with an internal thread, and the external thread is adapted to the internal thread.
