Description

Technical Field

[0001] This utility model belongs to the field of pipe fitting docking technology, specifically, it relates to a support device for automotive pipe fitting welding clamping docking equipment. Background Technology

[0002] Depending on the processing technology, automotive pipe fittings are divided into butt-welded pipe fittings (which are further divided into those with welds and those without welds), socket-welded and threaded pipe fittings, and flanged pipe fittings. One type of butt-welded automotive pipe fitting is pipe end to pipe end butt welding. Application No.: CN202322294256.5 (Announcement No.: CN220698739U) relates to the field of pipe welding and butt welding technology, and in particular to a welding clamping and butt welding device for automotive pipe fittings. The device includes a bracket and a push rod. The output shaft ends of the push rods are rotatably connected to a friction transmission machine through hinged seats. The inner ends of the front and rear limit frames are fixedly connected to the motor frame of a double-headed motor. The lower outer wall of the left rack is fixedly connected to the upper clamping seat, and the lower outer wall of the right rack is fixedly connected to the lower clamping seat. The two pipe fittings to be welded are respectively inserted between the front and rear clamping seats and clamping seat two. The double-headed motor is started, and the output shaft of the double-headed motor can drive the gears on both sides to rotate synchronously. The gears can then move through the rack and rack two. The rollers on the inner wall of the clamping seat and clamping seat two can stably clamp the pipe fittings, allowing the pipe fittings to rotate. However, pipes come in various lengths. The aforementioned patent uses rollers to clamp the pipes, but the distance between the rollers on both sides of the clamp is not adjustable. For longer pipes, there may be situations where the length of the pipe between the two clamps is less than the length of the pipe outside the two clamps. When the length of the pipe outside the two clamps is too long, the pipe will not be supported and will become unbalanced, causing the pipe to "droop" at one end due to its own weight. Utility Model Content

[0003] In view of this, the present invention provides a support device for automotive pipe welding clamping and docking equipment, which is used to solve the technical problem that the pipe will be unbalanced when it is not supported, resulting in the pipe "drooping" at the opposite end under its own weight.

[0004] This utility model is implemented as follows: This utility model provides a support device for welding clamping and docking equipment for automotive pipe fittings, which has a bracket. An extension plate is fixedly installed on the front and rear walls of the left side of the bracket, and a set of support components is provided on each of the two extension plates. Each set of support components includes two longitudinally arranged adjustment components, and each set of adjustment components includes two inclined plates arranged in an "X" shape. The top of each inclined plate is rotatably connected to a side roller, and the side roller contacts the outer wall of the cylindrical tube.

[0005] Based on the above technical solution, the support device of the automotive pipe welding clamping and butt welding equipment of this utility model can be further improved as follows: Furthermore, each of the inclined plates has a guide groove along its central axis, and a vertically moving guide rod is slidably connected in both guide grooves. A sliding rod is rotatably connected to the lower end of each inclined plate.

[0006] Furthermore, each set of adjustment components also includes two longitudinally arranged horizontal plates, with a vertical plate fixedly installed in the middle of the top wall of the horizontal plate. The vertical plate has a vertical groove, and the guide rod is slidably connected in the corresponding vertical groove.

[0007] Furthermore, each of the horizontal plates has two symmetrically arranged sliding grooves, and each sliding groove is slidably connected to a sliding rod.

[0008] Furthermore, telescopic rods are fixedly installed on the opposite end faces of the sliding rods, and a moving block is fixedly installed between two horizontally corresponding telescopic rods. The two moving blocks on each set of support components move synchronously in the longitudinal direction.

[0009] Furthermore, each of the horizontal plates has a through threaded hole in its transverse middle section, and a longitudinally arranged threaded rod is rotatably connected to each threaded hole, with one end of the threaded rod rotatably connected to the bearing seat.

[0010] Compared with the prior art, the beneficial effects of the support device of the automotive pipe welding clamping and docking equipment provided by this utility model are: by setting the support components, it can adapt to pipes of various lengths and diameters, and play a supporting role in the process of docking the pipes; it avoids the situation where the two pipes "droop" at one end due to insufficient support points under their own weight.

[0018] Example 1 like Figure 1-4 As shown, this utility model provides a support device for welding clamping and docking equipment for automotive pipe fittings, which has a bracket 1. An extension plate 11 is fixedly installed on the front and rear walls of the left side of the bracket 1, and a set of support components is provided on each of the two extension plates 11. Each set of support components includes two longitudinally arranged adjustment components. Each set of adjustment components includes two inclined plates 31 arranged in an "X" shape. The top of each inclined plate 31 is rotatably connected to a side roller 30, which contacts the outer wall of the cylindrical tube.

[0019] Optionally, in the above technical solution, each inclined plate 31 is provided with a guide groove 32 along its central axis, and a vertically moving guide rod 33 is slidably connected in both guide grooves 32. The lower end of each inclined plate 31 is rotatably connected with a sliding rod 23.

[0020] Optionally, in the above technical solution, each set of adjustment components also includes two longitudinally arranged horizontal plates 21. A vertical plate 34 is fixedly installed in the middle of the top wall of the horizontal plate 21. A vertical groove 35 is provided on the vertical plate 34, and the guide rod 33 is slidably connected in the corresponding vertical groove 35.

[0021] Optionally, in the above technical solution, each horizontal plate 21 has two symmetrically arranged sliding grooves 22, and each sliding groove 22 is slidably connected to a sliding rod 23.

[0022] Optionally, in the above technical solution, telescopic rods 24 are fixedly installed on the opposite end faces of the slide rods 23, and moving blocks 25 are fixedly installed between the two horizontally corresponding telescopic rods 24. The two moving blocks 25 on each set of support components move synchronously in the longitudinal direction.

[0023] Optionally, in the above technical solution, each horizontal plate 21 has a through threaded hole 41 in the middle of its transverse direction, and each threaded hole 41 is rotatably connected to a longitudinally arranged threaded rod 42, one end of which is rotatably connected to a bearing seat 43.

[0024] When the side roller 30 is at the highest position, the distance between the two side rollers 30 corresponding to each other in the lateral direction is the smallest, which can support the pipe fitting with the smallest outer diameter. When the side roller 30 is at the lowest position, the distance between the two side rollers 30 corresponding to each other in the lateral direction is the largest, which can support the pipe fitting with the largest outer diameter.

[0025] The two pipe fittings may have different lengths, so the positions of the two horizontal plates 21 on each support assembly can be adjusted individually through the threaded rod 42 and the threaded hole 41 to accommodate pipe fittings of different lengths. The threaded hole 41 and the threaded rod 42 do not occupy longitudinal space, and the side rollers 30 can be placed as close as possible.

[0026] Furthermore, a double-acting cylinder 12 is fixedly installed on each extension plate 11. The two movable ends of the double-acting cylinder 12 are arranged laterally and are fixedly connected to the movable block 25 on the same side. When the movable end of the double-acting cylinder 12 extends, the two movable blocks 25 move in opposite directions at the same time. When the movable end of the double-acting cylinder 12 retracts, the two movable blocks 25 move towards each other at the same time. The double-acting cylinder 12 adopts an existing product and is connected to an external air source.

[0027] Furthermore, two bearing seats 43 are fixedly installed on the extension plate 11. The bearing seats 43 are longitudinally symmetrically distributed about the double-acting cylinder 12. One end of the threaded rod 42 is rotatably connected to the bearing seat 43 through the bearing. The ends of the two threaded rods 42 located inside the bearing seat 43 are close to each other.

[0028] Among them, there are two inclined plates 31 that are intersected in an "X" shape. The intersection of the "X" is the guide rod 33, and the position of the intersection point will move up and down.

[0029] When the side roller 30 is at the lowest point of its stroke, the top wall of the side roller 30 is higher than the top wall of the vertical plate 34, so as to avoid the vertical plate 34 affecting the support of the side roller 30 for the pipe fitting.

[0030] After the pipe fitting is stably clamped by the rollers on the inner wall of the clamping seat and the clamping seat, the distance between the adjustment components on the two extension plates 11 is adjusted according to the length of the pipe fitting so that the inclined plates 31 of the two adjustment components are both below the pipe fitting. Then the side rollers 30 are moved up until the side rollers 30 abut against the pipe fitting. The upward movement of the side roller 30 is as follows: the double-acting cylinder 12 is activated to bring the two moving blocks 25 closer to each other, which drives the corresponding slide rod 23 to slide in the slide groove 22. Under the restriction of the guide rod 33 sliding vertically along the vertical slide groove 35, the lower ends of the inclined plates 31 of the same adjustment component are brought closer to each other. According to the characteristic of the "X" shaped cross arrangement, the upper ends of the inclined plates 31 are also brought closer to each other. Then the distance between the side rollers 30 becomes smaller and the side rollers 30 move upward until they abut against the lower half circle of the circumference of the pipe fitting. The length of the support component is adjusted as follows: by turning the threaded rod 42 to rotate it in place, the horizontal plate 21 moves forward or backward, and the length of the telescopic rod 24 is adjusted accordingly, so that the distance between the two corresponding vertical side rollers 30 changes.

[0031] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
