Description

Technical Field

[0001] This utility model relates to the field of welding wire feeding, and in particular to a novel welding wire feeding device. Background Technology

[0002] An existing patent (publication number: CN203209871U) discloses a novel welding wire feeding device. It includes a frame with a worktable on the frame. The worktable has a through hole, and a welding wire feeding motor is fixed to the bottom of the worktable. The power shaft of the welding wire feeding motor is connected to a rotating shaft, which extends upward through the through hole. A welding wire spool is fixed on the rotating shaft, and a welding wire guide device is provided on one side of the welding wire spool, which is fixed to the worktable. However, this device relies on the welding wire spool on the upper part of the worktable to feed the welding wire. Because the welding wire spool is fixed to the upper part of the rotating shaft, it may not be possible to quickly replace the welding wire spool after it is used up, which has certain limitations. Summary of the Invention

[0003] This utility model addresses the aforementioned shortcomings of existing technologies by providing a novel wire feeding device that uses a wire feed roller on the upper part of the worktable to feed the welding wire. When the wire feed roller needs to be replaced, the threaded cylinder positioning seat on the upper part of the rotating crossbeam is rotated, causing the inner threaded cylinder to lift the threaded cylinder positioning seat and simultaneously causing the wire feed roller clamp at the lower end of the support to disengage from the upper part of the wire feed roller. This releases the upper wire feed roller clamp from locking the wire feed roller, allowing the equipment to quickly replace the wire feed roller and thus increasing the adaptability of the equipment.

[0004] The objective of this utility model is achieved through the following technical solution:

[0005] A novel welding wire feeding device includes a base, a worktable, rollers, a lower tray, a crossbeam, a lead screw base, a guide rod, a bearing seat, and roller bearings. The upper part of the base is fixedly connected to the worktable. The worktable has a central shaft groove that is adapted to a central shaft and connects to it. The central shaft rotates within the central shaft groove. The lower part of the worktable is fixedly connected to a drive box, which is adapted to a worm gear and connects to it. The worm gear rotates within the drive box. The upper part is fixedly connected to the central shaft. The side of the drive box has a worm groove, which is adapted to the worm. The worm groove connects to the worm, and the worm rotates inside the worm groove. The worm meshes with the worm wheel on the side. The front of the drive box is fixedly connected to the worm motor. The output shaft of the worm motor is fixedly connected to the worm. The surface of the worktable has a roller groove, which is fixedly connected to the roller shaft. The roller shaft is adapted to the roller and connects to the roller. The roller rotates inside the roller shaft. The upper part of the central shaft is fixedly connected to the lower tray.

[0006] The support rollers rotate on the side of the lower tray, the front of the workbench is fixedly connected to the guide frame, the guide wheels rotate on the upper part of the guide frame, the rear of the workbench is fixedly connected to the column base, the upper part of the column base is fixedly connected to the equipment column, and the front of the equipment column is fixedly connected to the crossbeam.

[0007] The upper part of the crossbeam is fixedly connected to the lead screw base, the inside of the lead screw base is rotatably connected to the lead screw, the upper part of the lead screw is fixedly connected to the lead screw handle, the inside of the upper bracket is fixedly connected to the threaded cylinder positioning seat, the inside of the threaded cylinder positioning seat is fixedly connected to the internal threaded cylinder, the side of the upper bracket is fixedly connected to the guide rod, and the side of the crossbeam has a wire groove. Beneficial effects

[0008] 1. During the use of this utility model welding wire feeding device, the welding wire is fed through the welding wire roller on the upper part of the worktable. When it is necessary to replace the welding wire roller, the threaded cylinder positioning seat on the upper part of the rotating crossbeam is rotated. At the same time, the inner threaded cylinder drives the threaded cylinder positioning seat to rise, and at the same time, it drives the welding wire roller clamp at the lower part of the lower support to disengage from the upper part of the welding wire roller. This releases the upper welding wire roller clamp from locking the welding wire roller, so that the equipment can quickly replace the welding wire roller, thereby increasing the adaptability of the equipment.

[0009] 2. During the use of this utility model welding wire feeding device, the worm motor inside the worktable drives the worm gear to rotate. Because the transmission principle of the worm and worm gear has a self-locking function, the welding wire roller maintains the angle of rotation during the operation, thereby enhancing the stability of the equipment.

[0010] 3. During the use of the welding wire feeding device of this utility model, the welding wire roller is locked and stabilized by the welding wire roller clamp at the upper part of the lower tray and the lower part of the upper support shaft. The surface of the welding wire roller clamp has a stepped tooth structure, which allows the welding wire roller clamp to lock welding wire rollers of different inner diameters within a certain range, thereby further increasing the adaptability of the equipment.
