Technical Field

[0001] This utility model relates to the field of welding tooling technology, and in particular to a spot welding platform tooling. Background Technology

[0002] Spot welding fixtures are a type of tooling equipment used for spot welding operations to improve welding efficiency and quality.

[0003] In the current field of spot welding fixture technology, traditional spot welding platform fixtures often face a series of problems and challenges. One of the more prominent issues is that the structure of some spot welding platform fixtures is too complex. This complex structure not only increases the difficulty of design and manufacturing, but also leads to cumbersome and inconvenient operation, requiring operators to spend a lot of time and effort to familiarize themselves with and master its operation methods.

[0004] Furthermore, the manufacturing cost of traditional spot welding platform tooling is relatively high, which undoubtedly increases the production investment of enterprises and has a certain adverse impact on economic benefits. More importantly, these traditional spot welding platform toolings are not good at adapting to the spot welding needs of pipe fittings of different diameters. They are often only suitable for welding pipe fittings of specific diameters and cannot flexibly cope with pipe fittings of various diameters, which greatly limits their application scope in actual production and makes them inadequate when facing diverse production needs. Summary of the Invention

[0005] In response to the problems mentioned in the background art, this utility model provides a spot welding platform tooling.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A spot welding platform fixture includes a horizontally arranged base plate, characterized in that two side support plates are symmetrically arranged at both ends of the base plate, and a plurality of horizontally parallel lead screws are arranged between the two side support plates. A middle support plate is arranged on the lead screws, and a lead screw nut is arranged on the middle support plate. The middle support plate slides with the lead screws through the lead screw nut and is parallel to the side support plates.

[0008] The upper surfaces of both the side support plate and the middle support plate are provided with multiple spaced, semi-cylindrical grooves for pipe positioning.

[0009] Furthermore, the central part of the positioning groove of the pipe on the middle support plate is recessed, forming a structure that is high on both sides and low in the middle;

[0010] Furthermore, the pipe positioning groove is detachable from the side support plate and the middle support plate. Both the side support plate and the middle support plate are provided with a slide block and a slider. The slide block is integrated with the side support plate and the middle support plate. The slider is slidably mounted on the slide block and is elastically positioned and locked by an elastic positioning pin. The pipe positioning groove is provided on the slider.

[0011] Furthermore, the sliding trajectory of the slide block and the slider located on the side support plate or the middle support plate is located in the plane of the side support plate or the middle support plate or parallel to the plane of the side support plate or the middle support plate. There are multiple pipe positioning grooves on the slider, and the diameters of the semi-cylindrical grooves formed by the multiple pipe positioning grooves are different.

[0012] Furthermore, the sliding trajectory of the slide block and slider located on the side support plate or the middle support plate is perpendicular to the plane where the side support plate or the middle support plate is located. The number of sliders on a single slide block is consistent with the number of pipe positioning slots. Each slider is provided with a pipe positioning slot, and the diameter of the semi-cylindrical grooves formed by the pipe positioning slots on multiple sliders on the same slide block is different.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Example 1

[0022] As shown in the figure, this embodiment proposes a spot welding platform fixture for spot welding of workpieces, especially suitable for spot welding of pipes. Specifically, the spot welding platform fixture includes a horizontally arranged base plate 1, with two side support plates 2 symmetrically arranged at both ends of the base plate 1 for supporting the workpiece to be welded. In addition, a plurality of horizontally parallel lead screws 3 are arranged between the two side support plates 2. A middle support plate 4 is arranged on the lead screw 3, and a lead screw nut 5 is arranged on the middle support plate 4. The middle support plate 4 slides with the lead screw 3 through the lead screw nut 5 and is parallel to the side support plates 2, so that the middle support plate 4 can move parallel between the two side support plates 2 to adapt to the welding requirements of workpieces of different lengths.

[0023] To better position welded workpieces, especially pipe fittings, this embodiment provides multiple spaced, semi-cylindrical pipe fitting positioning grooves 6 on the upper surfaces of the side support plate 2 and the middle support plate 4. These grooves have different diameters and can accommodate pipe fittings of multiple diameters.

[0024] In summary, the spot welding platform tooling of this embodiment has a simple structure, is easy to operate, and has low manufacturing cost, making it suitable for spot welding of most pipe fittings.

[0025] Example 2

[0026] This embodiment proposes a spot welding platform fixture, wherein the central part of the pipe positioning groove 6 located on the central support plate 4 is recessed, forming a structure that is high on both sides and low in the middle. When spot welding is performed, the welding end face of the pipe to be welded can be placed on both sides of the pipe positioning groove 6 on the central support plate 4, and the position to be welded is located in the central recess of the pipe positioning groove 6. As welding proceeds, the central recess can be used for slag removal, and the weld point can also fall here, thereby avoiding the influence of pipe rotation on pipe positioning during continuous welding and ensuring spot welding accuracy.

[0027] Example 3

[0028] This embodiment proposes a spot welding platform fixture, wherein the pipe positioning groove 6 is detachable from the side support plate 2 and the middle support plate 4 to replace the positioning groove 6 of pipes with different diameters. The side support plate 2 and the middle support plate 4 are provided with a slide seat 7 and a slider 8. The slide seat 7 is integrated with the side support plate 2 and the middle support plate 4. The slider 8 is slidably disposed on the slide seat 7 and is elastically positioned and locked by the elastic positioning pin 9 to achieve quick installation and removal. The pipe positioning groove 6 is disposed on the slider 8.

[0029] In addition, the sliding tracks of slide 7 and slider 8 are designed to prevent mistakes.

[0030] Example 4

[0031] Based on the technical solution of Embodiment 3, this embodiment proposes a spot welding platform fixture, wherein the sliding trajectory of the slide block 7 and the slider 8 located on the side support plate 2 or the middle support plate 4 is located in the plane of the side support plate 2 or the middle support plate 4 or parallel to the plane of the side support plate 2 or the middle support plate 4. The slider 8 can be replaced as a whole. There are multiple pipe positioning grooves 6 on the slider 8, and the diameters of the semi-cylindrical grooves formed by the multiple pipe positioning grooves 6 are different.

[0032] Example 5

[0033] Based on the technical solution of Embodiment 3, this embodiment proposes a spot welding platform fixture, wherein the sliding trajectory of the slide block 7 and the slider 8 located on the side support plate 2 or the middle support plate 4 is perpendicular to the plane where the side support plate 2 or the middle support plate 4 is located. The number of sliders 8 on a single slide block 7 is consistent with the number of pipe positioning grooves 6. Each slider 8 can be replaced individually, and each slider is provided with a pipe positioning groove 6. Moreover, the diameter of the semi-cylindrical grooves formed by the pipe positioning grooves 6 on multiple sliders 8 on the same slide block 7 is different. Of course, according to the pipe diameter requirements of the pipe to be welded, multiple sliders 8 with the same pipe diameter can also be replaced.
