Description

Technical Field

[0001] This utility model relates to the field of welding path guidance technology, specifically a welding path guidance and positioning device. Background Technology

[0002] Welding, as a process with extremely high requirements for precision, consistency, and quality, relies heavily on precise workpiece positioning and accurate guidance of the welding path to ensure welding quality (such as weld formation and structural strength) and production efficiency. Currently, workpiece welding largely depends on manual marking for positioning or the use of specialized fixed fixtures. Manual marking is heavily influenced by the worker's experience and is prone to errors; while specialized fixed fixtures, although highly precise, typically only correspond to one specific workpiece, offering very low flexibility. Furthermore, the welding path needs to be determined based on pre-marked lines or the edge of the fixture, which not only demands a high level of skill from the welder but also makes it easy for fatigue to cause deviations during prolonged operation, making it difficult to guarantee consistent welding quality. Utility Model Content

[0003] To address the problem of difficulty in ensuring welding quality in the aforementioned technologies, this utility model provides a welding path guiding and positioning device.

[0004] The technical solution of this utility model is as follows: A welding path guiding and positioning device includes a positioning platform, a plurality of slide rails are provided above the positioning platform, a telescopic device is provided inside the slide rails, the telescopic device can move along the slide rails, a fixed seat is also provided above the positioning platform, a positioning plate is detachably provided at the end of the telescopic device facing the fixed seat, and the fixed seat is provided on the moving path of the positioning plate. A guiding device is also provided above the positioning platform. The guiding device includes a guide seat set on the positioning platform, and the guide seat is equipped with a movable laser device.

[0005] As a preferred technical solution, the laser device is provided in two sets, and the two sets of laser devices are parallel to each other.

[0006] To facilitate adjustment of the distance between the emitted beams of adjacent laser devices and to limit the width of the welding dimensions, the two sets of laser devices can move relative to each other in the same direction as the workpiece installation direction.

[0007] To ensure stability during the welding of the pipes to be welded, multiple slide rails set above the positioning platform are parallel to each other, and the slide rails located on both sides of the guide device are symmetrical about the guide device.

[0008] Furthermore, the welding path guiding and fixing device described above also includes a control device, which is disposed below one end of the positioning platform near the fixing seat.

[0009] To facilitate the fixing of the welded pipe, a strip groove is provided at one end of the fixing seat near the positioning plate, with the opening of the strip groove facing one side of the positioning plate.

[0010] As a preferred technical solution, the telescopic device is a telescopic cylinder, and the telescopic cylinder extends or retracts towards one end of the fixed base.

[0011] To facilitate adjustment of the laser beam emission angle, the guide seat includes a guide plate and a rotating plate. The guide plate is connected to the worktable, and the end away from the worktable is rotatably connected to the rotating plate.

[0012] Furthermore, in the welding path guiding and fixing device described above, the end of the rotating plate away from the guide plate is detachably connected to the laser equipment, and the moving direction of the laser equipment is perpendicular to the rotating plate.

[0013] As a preferred technical solution, the laser device is provided in two sets, and the two sets of laser devices are preset with an adjustable relative angle.

[0014] The beneficial effects of this utility model are as follows: This invention features multiple slide rails and guide devices arranged symmetrically about the guide devices above the positioning table. The slide rails have telescopic devices inside, and a positioning plate is installed at one end of each telescopic device. A fixed seat is provided on the surface of the positioning table to cooperate with the telescopic devices, which are aligned along the same straight line in their extension direction. This ensures that each time the workpiece is positioned, the multiple telescopic devices can push it to the same predetermined position, guaranteeing extremely high repeatability of workpiece positioning in mass production.

[0015] In addition, the guiding device includes a guide seat and at least one laser device. The laser device can move on the guide seat and can directly project a clear, accurate and position-adjustable laser line onto the workpiece surface, intuitively displaying the welding path. This greatly reduces the dependence on the welder's operating experience and technical level, and effectively improves the stability of welding quality. Attached Figure Description

[0019] Example 1 like Figure 1-4 The welding path guiding and fixing device shown is intended to solve the problems of easy deviation caused by traditional manual marking, low flexibility of special fixtures, and difficulty in ensuring quality stability during welding. This embodiment provides a welding path guiding and positioning device, which includes a positioning table 1, a slide rail 2, a telescopic device 3, a positioning plate 4, a fixing seat 5, a guiding device 6, and a control device 7.

[0020] Multiple slide rails 2 are arranged above the positioning platform 1, and the slide rails 2 are parallel to each other. In this embodiment, there are two slide rails 2. A telescopic device 3 is provided inside the slide rail 2. The telescopic device 3 can move along the length of the slide rail 2 to adjust its overall position. The telescopic device 3 is a telescopic cylinder, and its telescopic direction is consistent with the direction of movement of the telescopic device 3 inside the slide rail 2, which is towards the inside of the positioning platform 1.

[0021] A fixed seat 5 is also provided above the positioning table 1. The fixed seat 5 is detachably installed on the positioning table 1. A positioning plate 4 is provided at the end of the telescopic device 3 facing the fixed seat 5. The positioning plate 4 is detachably connected to the telescopic device 3. The fixed seat 5 is specifically located at the end of the movement path of the positioning plate 4 and works in conjunction with the positioning plate 4. In this embodiment, the positioning plate 4 is detachably connected to the telescopic device 3 by bolts. In addition, the positioning plate 4 in this embodiment can be replaced according to the specific shape of the workpiece to be welded and the clamping requirements, such as different shapes of positioning plates 4 such as arc, L-shaped or V-shaped. In this embodiment, the shape of the positioning plate 4 is arc-shaped. When used in conjunction with the positioning plate 4, the fixed seat 5 has a strip groove at the same height as the positioning plate 4. That is, the groove in the fixed seat 5 in this embodiment is arc-shaped. The opening of the strip groove faces the side of the positioning plate 4 and can serve as the final mechanical limit and calibration benchmark for the positioning plate 4 to push the workpiece to move. The strip groove has the same shape as the positioning plate 4, which can ensure that all workpieces are positioned to the same precise position every time.

[0022] Please refer to the appendix. Figure 1-4Above the positioning platform 1, a guiding device 6 is also provided. The guiding device 6 includes a guide seat 61 set on the positioning platform 1 and a laser device 62 mounted on the guide seat 61. The guide seat 61 consists of a guide plate 611 and a rotating plate 612. The lower end of the guide plate 611 is fixedly connected to the positioning platform 1, and the upper end is rotatably connected to the rotating plate 612. The rotating plate 612 can be adjusted in angle relative to the guide plate 611 in the vertical direction. At least one laser device 62 is mounted on the end of the rotating plate 612 away from the guide plate 611. To facilitate the maintenance and replacement of the laser device 62, the laser device 62 is detachably connected to the rotating plate 612.

[0023] In this embodiment, two sets of laser devices 62 are provided, parallel to each other. To facilitate adjustment of the distance between the emitted beams of the two sets of laser devices 62, allowing the welding process to occur between the laser beams, the two sets of laser devices 62 can move relative to each other. The direction of movement is consistent with the installation direction of the workpiece. In this embodiment, the relative movement between the laser devices 62 is achieved via a guide rail (not shown in the figure). The two sets of laser devices 62 can move independently or synchronously along the guide rail, or they can be fixed in any position by a locking mechanism. It is worth mentioning that the two sets of laser devices 62 in this embodiment can be used individually or in pairs.

[0024] A control device 7 is also installed below the end of the positioning platform 1 near the fixed base 5. The control device 7 integrates a controller and a power supply, and is electrically connected to each electric telescopic cylinder and laser equipment 62 via cables. The operator can control the synchronous movement or independent fine adjustment of all telescopic devices 3 through the control interface on the control device 7 or by receiving remote commands, thereby realizing the automated positioning and clamping of the workpiece.

[0025] See attached document Figure 1-4 When using this device, the specific operating steps are as follows: First, the operator selects the corresponding shape of the positioning plate 4 and the strip groove according to the shape of the workpiece to be welded (e.g., if the workpiece is a round tube, select the arc-shaped positioning plate 4; if the workpiece is a square tube, select the L-shaped positioning plate 4), and positions the moving device inside the slide rail 2; then, the outer side of the workpiece to be welded contacts the fixed seat 5 and the telescopic device 3 is activated through the control device 7, so that the telescopic device 3 moves toward the fixed seat 5, pushing the positioning plate 4 to contact the workpiece to the fixed seat 5, thereby achieving precise clamping of the workpiece.

[0026] The angle of the rotating plate 612 in the guide device 6 is manually adjusted to make it approximately perpendicular to the workpiece surface to be welded. According to the welding process requirements, the lateral position and spacing of the two sets of laser devices 62 on the rotating plate 612 are then adjusted so that the laser beams emitted by both form two clear and accurate guide lines on the workpiece surface. The welder or welding robot performs the welding operation between the two laser beams according to the path indicated by the laser lines. After welding is completed, all telescopic devices 3 are retracted via the control device 7, and the welded workpiece is removed. The device is then reset, ready for the next operation.

[0027] Example 2 This embodiment provides another welding path guiding and fixing device. The installation method of the laser device 62 differs from that in Embodiment 1, but the materials, specifications, and connection methods of the remaining components are the same as in Embodiment 1. The specific differences are: In order to enable the laser equipment 62 to meet the working conditions of wider welds and prevent welding from exceeding the restricted area, the two sets of laser equipment 62 in this embodiment are preset with an adjustable relative angle, that is, both sets of laser equipment 62 can rotate around the rotating plate 612 and can rotate relative to each other. The relative rotation angle is 0-120°. When the laser equipment 62 is manually adjusted, the light rays projected by the two sets of laser equipment 62 with the angle are still parallel on the workpiece.
