[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.
[0026] A precise positioning device for dislocation welding, such as Figure 1-Figure 7 As shown, the device comprises a bracket 1 and a welding head 2, which is fixed to the bottom of the bracket 1 via a support plate. The welding head 2 is used to weld the product. Specifically, the positioning device also includes a carrier 3, a first positioning plate 4, and a second positioning plate 5. The first positioning plate 4 and the second positioning plate 5 are mounted on the bracket 1. The first positioning plate 4 is provided with at least one first positioning groove 41, and the second positioning plate 5 is provided with at least one second positioning groove 51. The carrier 3 is provided with a workpiece position that mates with the product. A first positioning portion 31 and a second positioning portion 32 are provided on either side of the carrier 3, respectively, to mate with the first positioning groove 41 and the second positioning groove 51. The first positioning plate 4 and the second positioning plate 5 are provided with support edges 6 projecting oppositely, and the carrier 3 is supported on the support edges 6. The distance between the first positioning plate 4 and the second positioning plate 2 is greater than the width of the carrier 3. In this embodiment, there are three welding points. Therefore, the first positioning plate 4 has two first positioning grooves 41 spaced apart, and the second positioning plate 5 has a second positioning groove 51. By providing two first positioning grooves 41 and one second positioning groove 51, positioning in the X-axis and Y-axis directions is achieved. First, the first positioning portion 31 cooperates with a first positioning groove 41 on the left side. At this time, the welding head 2 corresponds to the first welding position of the product. After welding is completed, the carrier plate 3 is pushed to the right. At the same time, the second positioning portion 32 needs to cooperate with the second positioning groove 51. Therefore, the carrier plate 3 will move in the Y-axis direction while moving to the right, while the position of the welding head 2 is fixed. Therefore, the Y-axis position can be used to stagger the welding points. After the second welding point is completed, the carrier plate 3 continues to move to the right. At the same time, along the Y-axis position, the first positioning groove 41 on the right side cooperates with the first positioning portion 31 to weld the last welding point. Through the above-mentioned positioning device, the welding points are staggered to avoid the influence between the welding points caused by too close distance.
[0027] In the above embodiment, if Figure 1-Figure 7As shown, if there are four welding points, two first positioning grooves 41 and two second positioning grooves 51 are provided at intervals; staggered positioning of the four welding points can be achieved. If more welding points need to be positioned, the number of first positioning grooves 41 and second positioning grooves 51 can be increased alternately.
[0028] In one embodiment, if Figure 1-Figure 7 As shown, the first positioning groove 41 and the second positioning groove 51 are V-shaped structures. Preferably, the first positioning groove 41 has a first side 411 and a second side 412, and the second positioning groove 51 has a third side 511 and a fourth side 512; the first side 411 of the two first positioning grooves 41 is parallel to the fourth side 512, and the second side 412 of the two first positioning grooves 41 is parallel to the third side 511.
[0029] In one embodiment, if Figure 1-Figure 7 As shown, the distance from the intersection of the second side edges 412 of the two first positioning grooves 41 and the first side edges 411 to the bottom of the second positioning groove 51 is the distance between the endpoints of the first positioning portion 31 and the second positioning portion 32. Furthermore, the side walls of the first positioning groove 41 and the second positioning groove 51 cooperate with the first positioning portion 31 and the second positioning portion 32 to guide the movement of the carrier plate 3.
[0030] In one embodiment, if Figure 1-Figure 7 As shown, the first positioning plate 4 and the second positioning plate 5 are detachably mounted on the bracket 1. Different positioning plates can be selected according to different products and welding points to increase the adaptability of the positioning device.
[0031] In the above embodiment, if Figure 1-Figure 7 As shown, the first positioning plate 4 and the second positioning plate 5 are fixed to the bracket 1 by screws.
[0032] In one embodiment, if Figure 1-Figure 7 As shown, the bottom of the slide 3 is provided with a retaining groove 33. The first positioning plate 4 and the second positioning plate 5 are provided with retaining blocks 7 that cooperate with the retaining groove 33. The number and position of the retaining grooves 33 correspond to the welding points. In this embodiment, the product has three welding points, so there are three positioning grooves 33. The retaining grooves 33 and the retaining blocks 7 serve to assist in positioning.
[0033] In the above embodiment, if Figure 1-Figure 7As shown, the limiting groove 33 includes a first side wall 331 and a second side wall 332. The first side wall 331 is a vertical plane, and the second side wall 332 is an inclined surface. The shape of the limiting block 7 is the same as that of the limiting groove 33. The use of the inclined surface and the plane can achieve a one-way push effect and also serve as an auxiliary positioning function. After the first welding point is completed, the carrier plate 3 is pushed, and the second side wall 332 of the limiting groove 33 cooperates with the inclined surface of the limiting block 7. The carrier plate 3 moves horizontally and upward at the same time until the limiting block 7 corresponds to the next limiting groove 33.
[0034] In one embodiment, if Figure 1-Figure 7 As shown, the first positioning plate 4 and the second positioning plate 5 are transversely provided with slots, and the limiting block 7 is inserted into the slots. Preferably, the limiting block 7 is interference fit with the slots.
[0035] When the utility model is in use, Figures 1-10 As shown, the product is placed on the carrier 3, and the first positioning portion 31 of the carrier 3 cooperates with the first positioning groove 41 on the left side of the first positioning plate 4 to achieve positioning of the first welding point, as shown in FIG. Figure 8 After the welding is completed, the carrier 3 is pushed along the X axis to move so that it reaches the second welding point. During this process, the carrier 3 moves synchronously along the X axis and the Y axis so that the second positioning portion 32 cooperates with the second positioning groove 51. At this time, the second welding point is reached. Figure 9 After the welding is completed, it moves to the third welding point, and the carrier 3 moves synchronously along the X-axis and the Y-axis, so that the first positioning portion 31 cooperates with the first positioning groove 41 on the right side to position the carrier 3. At this time, it reaches the third welding point, and reaches the position shown in FIG. Figure 10 Status shown.
[0036] The above are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Without departing from the spirit and scope of the present invention, modifications or equivalent replacements of the present invention should be included in the scope of protection of the claims of the present invention.
