Description

Technical Field

[0001] The utility model relates to the field of cladding, in particular to an adjustable tooling for cladding of composite elbow pipe fittings. Background Art

[0002] At present, in the cladding industry, cladding of composite elbow pipes at different angles faces the following problems:

[0003] 1. Difficulty in angle placement: In the cladding industry, the production and processing of composite elbow pipe fittings has always been an important challenge faced by technicians. Especially on compact welding machines, these pipe fittings need to be accurately placed at different angles to complete the welding process. For small-sized elbow pipe fittings, workers can adjust their angles by manual operation to meet the needs of welding. However, when it comes to large-sized elbows, this simple method is no longer applicable. Due to the large size, it is difficult to achieve accurate angle placement by manpower alone.

[0004] 2. Difficulty in moving and calibrating the center of the circle: The process of moving and calibrating the center of the pipe fitting is often full of difficulties. Once the center of the pipe fitting is not accurately located after it falls to the ground, it needs to be lifted and moved or the center of the pipe needs to be adjusted by hitting the workpiece. Such operations are not only inefficient, but also accompanied by high labor costs and potential safety risks.

[0005] 3. Difficulty in fixing elbows: During the cladding process of the compact welding machine, the welding gun remains stationary, while the rotating disk at the bottom drives the workpiece to rotate. The elbow is fixed on the turntable. During the rotation process, the elbow may shift due to the rotation of the turntable, which may cause a difference in the thickness of the cladding on both sides.

[0006] Therefore, it is necessary to develop adjustable tooling for cladding welding of composite elbow pipe fittings in a targeted manner to solve the problems of difficulty in placing composite elbow pipe fittings at different angles, difficulty in moving and calibrating the center of the circle, and difficulty in fixing the elbow.

DETAILED DESCRIPTION

[0022] The technical solution of the utility model is further described below in conjunction with the accompanying drawings and specific implementation methods.

[0023] The utility model discloses an adjustable tool for surfacing welding of composite elbow pipe fittings, comprising a base part, a plane moving part, a workpiece fixing part and an angle adjustment part, wherein the base part comprises a compact welding machine optional platform 1 and a rectangular frame 2; the plane moving part comprises a slide rail 3 and a plane moving slider 8, two plane moving sliders 8 are nested on each slide rail 3, and the plane moving sliders 8 of different slide rails 3 are connected by a crossbeam 11; the workpiece fixing part comprises an L-shaped tool composed of a transverse beam 4 and a vertical beam 5, the L-shaped tool is fixed to the left and right positions in the middle of the crossbeam 11 by a hinge 13, and both sides of the upper end of the vertical beam 5 are provided with support blocks 7 for positioning the composite elbow pipe fitting 6; the angle adjustment part comprises a hinge 13 located at the front end of the L-shaped tool and a hinge 13 on the crossbeam 11, support rods 12 are provided at both ends of the crossbeam 11, and the angle adjustment part makes the support angle of the L-shaped tool be 30°.

[0024] Among them, the rectangular frame 2 is made of 4 square steels, and a pair of cylinders are provided below the two short sides of the rectangular frame 2, and the cylinders are inserted into the connection holes of the compact welding machine optional platform 1. The plane moving part is provided with 2 slide rails 3 and 4 plane moving sliders 8. The slide rail 3 is fixedly connected to the rectangular frame 2 by screws. The angle adjustment part rotates with the hinge 13 at the front end of the L-shaped tooling as the center of the circle, and the rear end of the L-shaped tooling is lifted by the support rods 12 at both ends of the crossbeam 11, so that the support angle of the L-shaped tooling is 30°. The support rod 12 is also connected to the crossbeam 11 by a hinge 13, and a positioning block 9 is provided at the bottom of the L-shaped tooling with the support rod 12. A stopper 10 for positioning the composite elbow pipe fitting 6 is provided at the end of the transverse beam 4. The plane moving slider 8 is connected to the external control system. An angle ruler 14 is provided at the end of the L-shaped tooling.

[0025] The method for using the adjustable tooling for composite elbow pipe cladding of the utility model comprises the following steps:

[0026] 1) Through an external control system, the L-shaped tooling consisting of the horizontal beam 4 and the vertical beam 5 is rotated to a horizontal angle using the hinge 13 at the front end of the L-shaped tooling as the center of the circle; and the angle ruler 14 is used to confirm whether the L-shaped tooling is level;

[0027] 2) hoist the composite elbow pipe fitting 6 into the L-shaped fixture, and automatically correct and level the composite elbow pipe fitting 6 through the support blocks 7 on both sides of the upper end of the vertical beam 5;

[0028] 3) When the composite elbow pipe fitting 6 is stable, the composite elbow pipe fitting 6 is fixed to the L-shaped fixture using a fastening belt, and the angle is adjusted through the hinge 13 at the front end of the L-shaped fixture until the support angle of the L-shaped fixture is 30°;

[0029] 4) The support rod 12 is rotated and erected through the hinge 13 at the bottom, so that the L-shaped tooling maintains a support angle of 30°, and the L-shaped tooling is stabilized through the hinge 13 and the support rod 12.

[0030] In the plane moving part of the utility model, the plane moving slider 8 in each group and the crossbeam 11 connected thereto jointly carry the workpiece above to realize the plane movement of the workpiece. The design of the plane moving part ensures the stable movement and precise positioning of the workpiece. The screws fix the plane moving slide rail 3 on the rectangular frame 2 to ensure the stability and accuracy of the slide rail 3. The plane moving slider 8 is nested on the slide rail 3, and the smooth movement of the workpiece is realized through the precise sliding mechanism. Each group of plane moving parts includes two plane moving sliders 8, which are connected by the crossbeam 11, thereby enhancing the stability and rigidity of the overall structure. This design enables each group of plane moving parts to carry the workpiece above, and through the synergistic effect of the two plane moving sliders 8, the stable movement of the workpiece on the plane is guaranteed. There are a total of two groups of such plane moving parts, which are respectively located on both sides of the workpiece, and through the connection of the crossbeam 11, they jointly carry the workpiece, so that the workpiece can be accurately moved and positioned on the plane.

[0031] The angle adjustment part of the utility model is the core part. The front end of the L-shaped tooling composed of the horizontal beam 4 and the vertical beam 5 uses a hinge 13 and a horizontal beam 11 to realize the rotation of the L-shaped tooling with the hinge 13 as the center of the circle, thereby adjusting the angle of the workpiece. At the same time, support rods 12 are provided at both ends of another group of horizontal beams 11, and the connection method with the horizontal beam 11 is a hinge structure. The length design of the support rod 12 enables the tooling to support 30° and achieve accurate angle adjustment. The combination of the L-shaped tooling and the horizontal beam 11 is cleverly used, and the flexible adjustment of the workpiece angle is achieved through a precise hinge connection. Specifically, the L-shaped tooling consists of two parts, the horizontal beam 4 and the vertical beam 5, and the front end thereof is cleverly connected to the horizontal beam 11 by using a hinge 13. This connection method not only ensures the stability of the tooling, but also enables the L-shaped tooling to realize free rotation with the hinge 13 as the center of the circle, thereby achieving the purpose of adjusting the angle of the workpiece. In order to enhance the accuracy and stability of the angle adjustment, the designer installed support rods 12 at both ends of the other group of horizontal beams 11. The connection between these support rods 12 and the crossbeam 11 also adopts a hinge structure, which ensures that the support rods 12 can flexibly adjust their positions as the crossbeam 11 moves, and ensures that the connection between the support rods 12 and the crossbeam 11 is sufficiently stable. The length of the support rods 12 is carefully calculated to ensure that the tooling can support an angle of 30°. This design not only makes the angle adjustment more precise, but also greatly improves the practicality and ease of operation of the tooling. In actual applications, the staff can easily achieve precise adjustment of the workpiece angle through simple operations to meet different production needs.

[0032] After precise angle adjustment, the composite elbow pipe fitting 6 is firmly mounted on the L-shaped tooling formed by the transverse beam 4 and the vertical beam 5. Next, in order to ensure that the center position of the pipe fitting is accurate, the operator can manually control the plane moving slider 8 to move back and forth to align the center. In addition, the operator can also input the corresponding distance on the operation panel, and the plane moving slider 8 will automatically move accurately according to the preset distance. Once the center position is confirmed and correct, the operator can lock the slider through the remote control to prevent the pipe fitting from sliding out of position due to the rotation of the bottom turntable during the surfacing process. The stability and accuracy of pipe processing are ensured.
