Description

Technical Field

[0001] This utility model belongs to the technical field of laser welding auxiliary devices, specifically relating to a robot laser welding intersection line welding fixing device. Background Technology

[0002] Intersection welding refers to welding two objects together. The shape of the intersection line depends on the shape, size, and relative position of the two solids. If the surfaces of both spatial objects are curved, the intersection line is a spatial curve; if the surfaces of both spatial objects are planar, the intersection line is a spatial broken line; if the surfaces of the two spatial objects are planar and curved respectively, the intersection line is a line enclosed by several planar curves.

[0003] Before a robot can weld two objects, the two components need to be fixed in place. Then, the machine can perform laser welding on the components. However, in the current technology, fixing the two components is complicated and takes a long time, which affects work efficiency. Utility Model Content

[0004] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a robotic laser welding intersection welding fixing device to solve the problems mentioned in the background art.

[0005] To achieve the above technical objectives, the technical solution adopted by this utility model is as follows:

[0006] A robotic laser welding intersecting line welding fixing device includes a mounting plate. A first positioning component and a second positioning component are mounted and connected to the upper side of the mounting plate, and a translation mechanism is mounted and connected between the first positioning component and the mounting plate. The second positioning component is fixedly connected to the mounting plate. The translation mechanism is used to adjust the distance between the first positioning component and the second positioning component. A support plate, fixedly connected to the mounting plate, is provided on the side near the second positioning component. The support plate has several evenly spaced arc-shaped slots on its upper side. The first positioning component and the second positioning component each include a first vertical positioning plate and a second vertical positioning plate, and multiple first positioning elements and second positioning elements that limit the upper side of the welded parts. A first assembly plate is mounted and connected to the lower side of the first vertical positioning plate and the second vertical positioning plate. A second assembly plate is mounted and connected to the lower side of the first positioning elements and the second positioning elements.

[0007] Further specifying, the first positioning component and the second positioning component have the same structure. The first positioning component includes a mounting base fixedly connected to the first assembly plate. A telescopic cylinder is mounted and connected to the upper side of the mounting base. A connecting block is mounted and connected to the output shaft of the telescopic cylinder. A vertical positioning pin is fixedly connected to the other end of the connecting block.

[0008] Further specifying, the translation mechanism includes a cylinder that is assembled and connected to the mounting plate, the output shaft of the cylinder is assembled and connected to one side of the mounting plate of the second positioning component, and the mounting plate has a limit strip fixedly connected to the other side of the mounting plate.

[0009] Furthermore, both the first assembly plate and the second assembly plate are provided with right-angled limiting plates on one side.

[0010] Furthermore, the first assembly plate has a pad connected to it by screws on the underside of the positioning pin.

[0011] Further, the mounting plate has locking components on both sides that are aligned on the same straight line. The locking components have the same structure as the first positioning component. A horizontal plate is placed on the lower side of the locking components, and the horizontal plate is located on the upper side of the welded component.

[0012] Compared with the prior art, the present invention has the following advantages:

[0013] This utility model has a simple structure, which facilitates the fixing of the welded parts. By setting the first positioning component and the second positioning component, the two outer sides of the welded parts are fixed. At the same time, by setting multiple first positioning components and second positioning components, the upper side of the vertical rod is fixed, ensuring the stability of the welded parts during the welding process.

[0014] This invention achieves positioning of the upper middle part of the welded part through a simple structure by setting positioning components on both sides of the mounting plate and installing a horizontal plate on the lower side of the positioning components, thus preventing the welded part from moving up and down when the robot is performing laser welding.

[0015] This invention, by setting a translation component, allows the distance between the second positioning component and the first positioning component to be adjusted, thereby enabling the fixing of welded parts of different sizes. Attached Figure Description

[0026] To enable those skilled in the art to better understand this utility model, the technical solution of this utility model will be further described below in conjunction with the accompanying drawings and embodiments.

[0027] like Figure 1-4 As shown, the robotic laser welding intersection welding fixing device includes a mounting plate 1. A first positioning component 2 and a second positioning component 3 are mounted and connected to the upper side of the mounting plate 1. A translation mechanism 4 is mounted and connected between the first positioning component 2 and the mounting plate 1. The second positioning component 3 is fixedly connected to the mounting plate 1. The translation mechanism 4 is used to adjust the distance between the first positioning component 2 and the second positioning component 3. A support plate 5 is fixedly connected to the mounting plate 1 on the side closer to the second positioning component 3. Several arc-shaped slots are evenly opened on the upper side of the support plate 5. The first positioning component 2 and the second positioning component 3 respectively include a first vertical positioning plate 21 and a second vertical positioning plate 31, and multiple first positioning elements 22 and second positioning elements 32 that limit the upper side of the welded parts. A first assembly plate 23 is mounted and connected to the lower side of the first vertical positioning plate 21 and the second vertical positioning plate 31. A second assembly plate 33 is mounted and connected to the lower side of the first positioning elements 22 and the second positioning elements 32.

[0028] In this embodiment, a first positioning component 2 and a second positioning component 3 for fixing the welded parts are installed on the upper side of the mounting plate 1. A translation mechanism 4 is used to move the second positioning component 3, thereby adjusting the distance between the second positioning component 3 and the first positioning component 2 according to the size of the welded parts, thus fixing the welded parts. The welded parts are composed of multiple arc-shaped plates, and the ends of the multiple arc-shaped plates are welded to a vertical rod. A robot welds the arc-shaped plates to the vertical rod. A support plate 5 is used to place the arc-shaped plates of the welded parts. The lower side of the arc-shaped plates is located in the arc-shaped groove opened in the support plate 5. The first vertical positioning plate 21 and the second vertical positioning plate 31 are used to abut against the side of the vertical rod, so that the two ends of the arc-shaped plates are in close contact with the vertical plate. The first positioning component 22 and the second positioning component 32 are used to abut against the upper side of the vertical rod, such as... Figure 4 As shown, the welded part has a different shape. When the size of the arc plate in the middle of the welded part changes, the welded part can be fixed by adjusting the distance between the first positioning component 2 and the second positioning component 3.

[0029] Reference Figure 3 The first positioning component 22 and the second positioning component 32 have the same structure. The first positioning component 22 includes a mounting base 221 fixedly connected to the first assembly plate 23. A telescopic cylinder 222 is mounted and connected to the upper side of the mounting base 221. A connecting block 223 is mounted and connected to the output shaft of the telescopic cylinder 222. A vertical positioning pin 224 is fixedly connected to the other end of the connecting block 223. In this embodiment, the telescopic rod 222 controls the raising and lowering of the connecting block 223 in the first positioning component 22, so that the positioning pin 224 abuts against the vertical rod. The connecting block 223 is used to position the positioning pin 224 above the vertical rod, and to contact the vertical rod when it moves down.

[0030] Reference Figure 1-2 The translation mechanism 4 includes a cylinder 41 that is assembled and connected to the mounting plate 1. The output shaft of the cylinder 41 is assembled and connected to one side of the mounting plate 33 of the second positioning component 3. A limit strip 11 is fixedly connected to the other side of the mounting plate 33. In this embodiment, the translation mechanism 4 is used to move the second component 3, thereby positioning both sides of the welded part according to the size of the welded part. The limit strip 11 is used to restrict the movement direction of the mounting plate 33.

[0031] Reference Figure 3 The first assembly plate 23 and the second assembly plate 33 are each provided with a right-angled limiting plate 6 on one side. In this embodiment, the limiting plate 6 positions one side of the welded part.

[0032] Reference Figure 3 The first assembly plate 23 has a pad 24 connected to its underside by screws on the locating pin 224. In this embodiment, the pad 24 is used to support the welded parts and prevent the underside of the welded parts from directly contacting the mounting plate.

[0033] Reference Figure 2 The mounting plate 1 has locking members 7 on both sides, which are aligned on the same straight line. The locking members 7 have the same structure as the positioning members 22. A horizontal plate is placed under the locking members 7, and the horizontal plate is located on the upper side of the welded part. In this embodiment, by placing the horizontal plate under the locking members 7 and then controlling the positioning pins in the positioning members 22 to move downward, the two ends of the horizontal plate are fixed, so that the horizontal plate contacts the upper side of the welded part, thereby preventing the welded part from moving in the vertical direction.

[0034] The control method of this utility model is automatic control through a controller. The control circuit of the controller can be implemented by simple programming by those skilled in the art. The power supply is also common knowledge in the field. Since this utility model is mainly used to protect mechanical devices, the control method and circuit connection will not be explained in detail.

[0035] The above embodiments are merely illustrative of the principles and effects of this utility model and are not intended to limit the scope of this utility model. Any person skilled in the art can modify or alter the above embodiments without departing from the spirit and scope of this utility model. Therefore, all equivalent modifications or alterations made by those skilled in the art without departing from the spirit and technical concept disclosed in this utility model should still be covered by the claims of this utility model.
