AI Technical Summary
The existing semi-automatic welding trolleys cannot realize the full process of welding of the cover of single-piece welds of low-speed diesel engine frames, especially when they cannot walk near the end, resulting in discontinuity of the welds and unreliable welding quality.
A single-chip semi-automatic welding car extension device for low-speed diesel engine frame is designed, and a right-angle frame is formed by combining the back plate, support plate, support rod and adjustment seat. The semi-automatic welding car holds the welding gun mechanically and travels along the frame guide slide plate and triangle plate to realize continuous welding of the welding gun.
The integrity of the weld cover surface and reliability of welding quality are achieved, ensuring the continuous weld seam and the stable welding process, and improving welding efficiency and quality.

Technical Field
[0001] The invention relates to a low-speed diesel engine frame single-piece semi-automatic welding trolley extension device. Background Art
[0002] The low-speed diesel engine frame single piece adopts semi-automatic welding trolley to carry out weld capping, but due to the characteristics of product structure, the existing semi-automatic welding trolley cannot realize the whole process of weld capping. Near the end, the semi-automatic welding trolley cannot move, and the remaining welds at the back can only be repaired manually. The welds are not welded continuously, the weld integrity is unreliable, and the weld quality is unstable.

[0004] The invention is a frame single-piece semi-automatic welding trolley extension device, which realizes the integrity of the weld seam cover and the reliability of the quality by utilizing the semi-automatic welding trolley.
[0005] The low-speed diesel engine frame single-piece semi-automatic welding trolley extension device of the present invention (see the attached drawings) is characterized in that: a back plate (8), a support plate (7), a support rod (9) and an adjustment seat (10) are provided, the upper surface of the back plate (8) and the upper surface of the frame guide plate (3) are coplanar and butt-jointed, the support plate (7) and the frame triangle plate (2) are coplanar and butt-jointed in a horizontal coplanar manner; the edges of the back plate (8) and the support plate (7) are butt-jointed to form a mutually perpendicular fixed connection, the support plate (7) is provided with arranged support rods (9) below, and the support rods (9) and the adjustment seat (10) are connected by a threaded pair. The height of the support plate (7) is adjusted by a threaded pair between a support rod (9) and an adjustment seat (10); the back plate (8) and the support plate (7) are welded to form a right-angle frame; the semi-automatic welding trolley (4) mechanically clamps the welding gun (5) from the left end of the frame triangle plate (2) along the frame guide plate (3) to the right to the support plate (7), thereby achieving full weld coverage of the welding gun (5).
[0006] The low-speed diesel engine frame monolithic semi-automatic welding trolley extension device of the present invention comprises a back plate (8), a support plate (7), a support rod (9) and an adjustment seat (10). The back plate (8) and the support plate (7) are welded to form a right-angled weld seam that is colinearly connected with the weld seams between the frame guide plate (3) and the frame triangle plate (2) of the frame monolithic; the height of the support plate (7) is adjusted by a threaded pair between the support rod (9) and the adjustment seat (10) to adapt to the continuous welding of the frame back plate monolithic with different specifications. The semi-automatic welding trolley (4) mechanically clamps the welding gun (5) from the left end of the frame triangle plate (2) along the guide plate (3) of the frame to the right to the support plate (7), keeps the weld seam on the right side between the guide plate (3) and the triangle plate (2) continuously welded, thereby realizing that all the welding guns (5) of the semi-automatic welding trolley realize continuous welding of the weld seams.

[0009] The embodiments of the present invention are further described below in conjunction with the accompanying drawings.
[0010] The low-speed diesel engine frame single-piece semi-automatic welding trolley extension device comprises a back plate (8), a support plate (7), a support rod (9) and an adjustment seat (10). The upper surface of the back plate (8) is coplanar with the upper surface of the guide plate (3) of the frame and is butted against each other. The support plate (7) and the frame triangle plate (2) are butted against each other in a horizontal coplanar manner. The edges of the back plate (8) and the support plate (7) are butted against each other to form a mutually vertical fixed connection. Arranged support rods (9) are arranged below the support plate (7). The support rods (9) and the adjustment seat (10) are connected through a threaded pair. The extension device is composed of the back plate (8), the support plate (7), the support rod (9) and the adjustment seat (10). The back plate (8) and the frame guide plate (3) are butted against each other (4) in a vertical direction and are in the same plane in front. The support plate (7) and the frame triangle plate (2) are butted against each other in a horizontal direction and are in the same plane in top. The height of the support plate (7) is adjusted through a threaded pair between the support rod (9) and the adjustment seat (10). After adjustment, the height of the support plate (7) is consistent with the height of the frame triangle plate (2) supported by the support seat (1). The back plate (8) and the support plate (7) form a right-angle frame by welding, so that the semi-automatic welding trolley (4) can continuously move on the frame triangle plate (2) and the support plate (7) to weld the entire weld. The semi-automatic welding trolley (4) clamps the welding gun (5) by mechanical means. The semi-automatic welding trolley (4) has guide wheels extending toward the back plate (8) and the frame guide slide plate (3), which play a role in maintaining the distance between the back plate (8) and the frame guide slide plate (3), so that it moves in a straight line in the horizontal direction, thereby ensuring that the welding gun can reliably and continuously weld along the weld, so that the semi-automatic welding trolley (4) can move from the left end of the frame triangle plate (2) along the frame guide slide plate (3) to the right to the support plate (7) to continuously weld the weld, thereby realizing that the welding gun (5) can completely cover the weld and work continuously and reliably and weld the weld continuously. The frame single-piece semi-automatic welding trolley extension device of the present invention realizes the integrity of the weld seam cover surface and the reliable stability of welding by utilizing the semi-automatic welding trolley.
