Description

Technical Field

[0001] The utility model relates to the field of welding and cutting tools, in particular to a multi-point positioning, clamping and rotating welding and cutting tool. Background Art

[0002] Traditional sheet metal processing, especially for curved sheet metal, often involves complex tooling design and operational processes to ensure precise welding and cutting. Existing welding and cutting tooling presents difficulties in clamping and positioning curved sheet metal, and may not be capable of rotary processing, resulting in low production efficiency and inconsistent processing quality.

[0003] In existing technology, some welding and cutting tooling designs use platform fixation or single-point clamping, which cannot flexibly adapt to the processing requirements of curved metal plates. At the same time, the alignment and fixation of positioning holes are also one of the challenges in traditional tooling design.

[0004] Therefore, in order to meet the clamping, positioning and rotation processing requirements during the processing of curved metal plates, there is an urgent need for a multi-point clamping rotary welding and cutting tool that can effectively solve the above problems. Utility Model Content

[0005] The technical problem to be solved by the utility model is: to solve the above-mentioned technical problems and provide a multi-point positioning clamping rotary welding and cutting tool that can perform multi-point positioning clamping on arc-shaped metal plates and realize rotary processing of arc-shaped metal plates.

[0021] Preferably, the welding and cutting mechanism further includes a clamping device, which includes a fixed portion, a movable portion, and an adjusting member connecting the fixed portion and the movable portion.

[0022] The technical effects that can be achieved by this utility model include the following:

DETAILED DESCRIPTION

[0029] The present invention will be further described below with reference to the accompanying drawings and examples, but these specific implementation schemes do not limit the protection scope of the present invention in any way.

[0030] Example 1

[0031] See attached Figure 1-3 A multi-point positioning, clamping, rotary welding and cutting tool comprises a hollow base 1, a circular platform 2 arranged on the hollow base 1, a driven mechanism connected to the circular platform 2, a driving mechanism 3 arranged in the hollow base 1 and connected to the driven mechanism, and a welding and cutting mechanism 4 arranged on one side of the hollow base 1; a plurality of positioning holes 5 distributed from the center to the circumference are provided on the circular platform 2, and positioning pins 6 are provided in at least three of the positioning holes 5.

[0032] In this embodiment, the hollow base 1 is a cubic structure with a circular platform 2 disposed on top. Multiple positioning holes 5 are provided on the circular platform 2 to align with the connection holes on the curved metal plate to be processed. In this embodiment, the curved metal plate has three connection holes, corresponding to the three positioning holes 5 on the circular platform 2. When the connection holes are aligned with the positioning holes 5, positioning pins 6 are inserted into the holes to achieve multi-point clamping and positioning.

[0033] In this embodiment, a servo motor 7 is mounted on the inner bottom of the hollow base 1. This servo motor 7 is connected to a driving gear 8 via an output shaft. A driven gear 9 is connected to the bottom of the circular platform 2 via a driven shaft. Driven gear 9 meshes with driving gear 8, and the servo motor 7 drives the circular platform 2 to rotate.

[0034] In this embodiment, a welding gun holder 10 is welded to one side of the top of the hollow base 1. The holder 10 comprises a rectangular tube holder. A transverse adjustment mechanism, which adjusts the horizontal position of the welding gun, is mounted on the transverse tube holder of the rectangular tube holder. The transverse adjustment mechanism is movably connected to a longitudinal adjustment mechanism. The transverse adjustment mechanism enables precise transverse positioning of the welding gun, while the longitudinal adjustment mechanism controls longitudinal movement of the welding gun, allowing the welding gun to be flexibly adjusted to the desired welding position. Furthermore, the rotating adjustment mechanism allows the welding gun to be flexibly rotated during welding, adapting to welding requirements at different angles and positions.

[0035] The above-mentioned lateral adjustment mechanism consists of a horizontally arranged sliding guide rail 11 and a sliding adjustment block 12 with a thread. The sliding adjustment block 12 moves left and right on the sliding guide rail 11 by adjusting the tension mechanism on one side, thereby driving the welding gun to be adjusted in the lateral direction.

[0036] The longitudinal adjustment mechanism includes a vertically arranged guide rod 13 and a sliding sleeve 14 matched therewith, and the sliding sleeve 14 moves up and down through the threaded sliding adjustment block 12. The surface of the guide rod 13 is provided with a scale to facilitate the operator to make precise adjustments.

[0037] The above-mentioned rotation adjustment mechanism consists of a rotation joint 15 installed at the end of the horizontal pipe rack and an adjustment handle 16 for locking the rotation joint 15. The rotation joint 15 allows the welding gun to rotate 360 ​​degrees around its axis, and the adjustment handle 16 is used to lock the rotation angle of the welding gun.

[0038] A gun clamp is installed at the rotary joint 15 . The gun clamp includes a fixed portion 17 , a movable portion 18 , and an adjusting bolt 19 connecting the fixed portion 17 and the movable portion 18 . A welding gun 20 is fixed between the fixed portion 17 and the movable portion 18 .

[0039] The working principle and method of the multi-point positioning clamping rotary welding and cutting tool in the above embodiment are:

[0040] Step 1: The operator first places the arc-shaped metal plate to be processed on the circular platform 2, aligns the three connecting holes on the arc-shaped metal plate with the corresponding three positioning holes 5 on the circular platform 2, and inserts the positioning pins 6 into the aligned holes to achieve multi-point clamping positioning to ensure that the arc-shaped metal plate is firmly fixed on the circular platform 2.

[0041] Step 2: The operator adjusts the horizontal position of the welding gun 20 through the lateral adjustment mechanism on the welding gun holder 10, adjusts the vertical position of the welding gun 20 using the longitudinal adjustment mechanism, and adjusts the angle of the welding gun 20 using the rotation adjustment mechanism; if necessary, the clamping force of the welding gun 20 between the fixed part 17 and the movable part 18 can be adjusted by adjusting the adjusting bolt 19 on the gun clamp.

[0042] In the third step, the operator starts the servo motor 7 arranged on the inner side of the bottom of the hollow base 1. The servo motor 7 drives the driving gear 8 to rotate through the output shaft. The driving gear 8 engages with the driven gear 9, driving the driven shaft connected to the circular platform 2 to rotate. The rotation of the driven shaft drives the circular platform 2 and the arc-shaped metal plate fixed thereon to rotate.

[0043] In the fourth step, as the circular platform 2 rotates, the operator can perform welding or cutting operations. During the processing, if the position of the welding gun 20 needs to be adjusted, the relevant steps in the second step can be repeated; the operator can adjust the speed of the servo motor 7 at any time according to the processing requirements to control the rotation speed of the circular platform 2.

[0044] In the fifth step, when the welding or cutting operation is completed, the operator stops the servo motor 7 to stop the rotation of the circular platform 2, removes the positioning pin 6, releases the fixation of the arc-shaped metal plate, and removes the processed arc-shaped metal plate from the circular platform 2.

[0045] In summary, the technical effects that can be achieved by a multi-point positioning clamping rotary welding and cutting tool are as follows:

[0046] 1. By providing a circular platform with multiple positioning holes distributed from the center toward the circumference and using locating pins aligned with the connection holes on the curved metal plate to be processed, a multi-point positioning and clamping system is formed. Combined with the driving and driven mechanisms within the hollow base, this system enables stable clamping and rotational processing of the curved metal plate. Compared to traditional platform-fixed or single-point clamping methods, this invention effectively solves the problems of difficult clamping and positioning of curved metal plates and the inability to perform rotational processing, significantly improving processing stability, precision, and efficiency.

[0047] 2. By incorporating lateral, longitudinal, and rotational adjustment mechanisms into the welding gun holder, a fully adjustable welding system is formed, enabling precise positioning and angle adjustment of the welding gun in three dimensions. Compared to the limitations of traditional welding and cutting tooling, which struggles to adapt to varying sizes of curved metal sheets, this invention effectively solves the problem of precise control of the welding gun's position and angle, significantly improving the tooling's flexibility and adaptability, ensuring high-quality processing of curved metal sheets of varying sizes and shapes.

At the same time, the various parameters, materials, and processes mentioned in the above embodiments are not exclusive. Without departing from the technical essence of the present invention, ordinary technicians in this field can make various alternatives, and these alternatives should also be considered to fall within the scope of protection of the present invention.
