Therefore, other examples of exemplary embodiments may have different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so once a certain item is defined in one drawing, it does not need to be further discussed in subsequent drawings.

[0026] Reference below Figures 1 to 3 , the utility model is further described as follows:

[0027] The automobile rear shock absorber lifting ring double-gun servo welding machine is characterized by comprising: a fixed base plate 1; a slide part 2, fixedly connected to the fixed base plate 1; a fixed pressing part 3, fixedly connected to the slide part 2; a welding part 4, fixedly connected to the fixed base plate 1, and symmetrically distributed on both sides of the slide part 2.

[0028] In this embodiment, the slide part 2 includes: a guide rail slide 21, which is connected to the fixed base plate 1 and can slide relative to the fixed base plate 1 in the long side direction of the guide rail slide 21; and a bottom cover fixed base 22, which is fixedly connected above one end of the guide rail slide 21.

[0029] In this embodiment, the fixed pressing part 3 includes:

[0030] The fixed plate 31 is fixedly connected to the guide rail slide 21 and can slide with the guide rail slide 21; the lifting ring pressing cylinder 32 is fixedly connected to the upper end of the fixed plate; the lifting ring fixing pressing device 33 is fixedly connected to the lifting ring pressing cylinder 32.

[0031] In this embodiment, the welding part 4 includes: a welding gun guide rail 41, which is fixedly connected to the fixed base plate 1; an adjustment bracket 42, which is connected to the welding gun guide rail 41 and slides along the welding gun guide rail 41; a welding gun thrust cylinder 43, which is fixedly connected to the upper end of the adjustment bracket 42; a welding gun fixing fixture 44, which is fixedly connected to the welding gun thrust cylinder 43; and a welding gun 45, which is fixedly connected to the welding gun fixing fixture 44.

[0032] During the welding process, the welding part 4 is used to adjust the position of the welding gun 45. After the position adjustment is completed, welding is performed.

[0033] In this embodiment, the guide rail slide 21 is connected to a servo cylinder, and the servo cylinder can drive the guide rail slide 21 to move relative to the fixed base plate 1.

[0034] The use of servo cylinders can achieve high-precision control. By connecting with control systems such as host computers, high-precision motion control can be achieved, thereby achieving high-precision welding effects.

[0035] In this embodiment, a groove is provided on the bottom cover fixing base 22, which can tightly fix the welding workpiece and prevent relative movement with the bottom cover fixing base 22. A semicircular accommodation space is provided at the lower end of the lifting ring fixing pressing device 33, which can tightly clamp the workpiece to be welded.

[0036] By using the corresponding fixing devices provided on the bottom cover fixing base 22 and the lifting ring fixing pressing device 33, different parts of the welding assembly can be firmly fixed, and relative displacement does not occur during the welding process, thereby ensuring the welding effect.

[0037] In an optional embodiment, an air claw is provided at the lower end of the lifting ring fixing and pressing device 33. By providing the air claw, welding workpieces of different specifications can be clamped and fixed, so that the automobile rear shock absorber lifting ring double-gun servo welding machine of the present application has a wider application range and stronger adaptability.

[0038] In this embodiment, a rectangular frame with the same bottom length and width as the fixed bottom plate 1 is connected above the fixed bottom plate 1. The height of the rectangular frame is higher than the fixed pressing part 3. A welding slag protective cover 5 is installed on at least one surface of the rectangular frame. The welding slag protective cover 5 can effectively prevent the welding slag generated during the welding process from splashing everywhere, which not only improves the welding environment, but also enhances the safety of the operator.

[0039] After the welding workpiece is completed, all operations in the subsequent welding process are controlled by mechanical automation. The specific control principle is as follows: Figure 3 shown.

[0040] The specific welding process is as follows:

[0041] The bottom cover fixing base 22 puts the bottom cover, the lifting ring fixing pressing device 33 is put on the lifting ring and clamped, the automatic start button is pressed, the lifting ring pressing cylinder 32 descends, so that the lifting ring to be welded is pressed and fitted together with the bottom cover, and the left and right welding gun propulsion cylinders 43 drive the welding gun fixing fixture 44 and the welding gun 45 to advance inward at the same time, the guide rail slide 21 moves inward, and at the same time the welding gun 45 feeds the welding wire and starts the welding arc, moves to the welding set distance, and the welding gun 45 closes the arc and stops firing and stops feeding the welding wire. The left and right welding gun propulsion cylinders 43 are retracted together with the welding gun fixing fixture 44 and the welding gun 45 on both sides at the same time, the guide rail slide 21 returns to its initial position, the lifting ring pressing cylinder 32 rises, and the workpiece on the lifting ring fixing pressing device 33 is removed with a tool. The processing speed is significantly improved, the workpiece status and processing effect are observed, and the processing is completed.

[0042] The utility model adopts a servo module to digitally control the welding speed, welding length, etc., avoiding the quality risks caused by the old equipment relying on sensors to control the welding length. The transformation improves the overall performance of the equipment, while improving the accuracy of the equipment and reducing the equipment failure rate.

[0043] The use of standard linear guides avoids the problem of wear and tear of the old dovetail groove affecting welding quality. It saves procurement costs and improves the economic value of the enterprise while meeting product requirements.

[0044] In the description of the present utility model, it needs to be understood that the directions or positional relationships indicated by directional words such as "front, back, up, down, left, right", "lateral, vertical, perpendicular, horizontal" and "top, bottom" are usually based on the directions or positional relationships shown in the drawings, and are only for the convenience of describing the present utility model and simplifying the description. Unless otherwise specified, these directional words do not indicate or imply that the device or element referred to must have a specific direction or be constructed and operated in a specific direction, and therefore cannot be understood as limiting the scope of protection of the present utility model; the directional words "inside and outside" refer to the inside and outside relative to the contours of each component itself.

[0045] For ease of description, spatially relative terms such as "above", "above", "on the upper surface of", "above", etc. may be used here to describe the spatial positional relationship between a device or feature and other devices or features as shown in the figure. It should be understood that spatially relative terms are intended to include different orientations of the device in use or operation in addition to the orientation described in the figure. For example, if the device in the accompanying drawings is inverted, the device described as "above other devices or structures" or "above other devices or structures" will be positioned as "below other devices or structures" or "below other devices or structures". Thus, the exemplary term "above" can include both "above" and "below". The device can also be positioned in other different ways (rotated 90 degrees or in other orientations), and the spatially relative descriptions used here are interpreted accordingly.

[0046] In addition, it should be noted that the use of terms such as "first" and "second" to limit components is only for the convenience of distinguishing the corresponding components. If not otherwise stated, the above terms have no special meaning and therefore cannot be understood as limiting the scope of protection of the utility model.

[0047] The above description is only the preferred embodiment of the utility model, and is not intended to limit the utility model. For those skilled in the art, the utility model can have various modifications and changes. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
