[0027] 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.

[0028] Example:

[0029] Please see Figure 1 - Figure 7 In this embodiment, a front bulkhead and wheel cover positioning welding fixture includes a welding table 1 and a welding part 2 installed on the welding table 1. The welding part 2 is composed of two wheel covers and a middle front bulkhead.

[0030] The welding table 1 is equipped with a side positioning mechanism 101 and a side positioning mechanism 102 for positioning and supporting the wheel covers on both sides. The welding table 1 is also equipped with a central positioning mechanism 103 for positioning and supporting the central front panel. The side positioning mechanism 101 and the side positioning mechanism 102 are connected in the same way.

[0031] Side positioning mechanism 101 and side positioning mechanism 2 102 are located on opposite sides of the central positioning mechanism 103, and side positioning mechanism 101 and side positioning mechanism 2 102 are symmetrically distributed.

[0032] Furthermore, the positioning stroke of side positioning mechanism 101 is before the positioning stroke of side positioning mechanism 2 102, and the positioning stroke of side positioning mechanism 2 102 is before the positioning stroke of the central positioning mechanism 103.

[0033] First, the welding part 2 is placed and supported by the welding table 1, and the two wheel covers on both sides and the front panel in the middle of the welding part 2 are positioned and placed by the side positioning mechanism 101, the side positioning mechanism 2 102 and the middle positioning mechanism 103 respectively, so that they are placed stably and accurately. Then, the welding part 2 is clamped in sequence to make the connection point achieve a precise positioning connection effect.

[0034] After the welding part 2 is placed as a whole, the side positioning mechanism 101 is activated to first position and tighten one side wheel cover. Only then can the side positioning mechanism 102 position the wheel cover on one side. After the side wheel cover is accurately positioned, the middle positioning mechanism 103 is activated to position and tighten the middle front panel. This ensures that the positioning stroke of the device is sequentially positioned, which guarantees the fixation of the positioning process, prevents accidental operation of the positioning mechanism, and ensures the accurate positioning of the welding part 2 as a whole, thereby improving the subsequent welding effect.

[0035] The side positioning mechanism 101 consists of a drive cylinder 1011 for driving the support, a clamping arm 1017 for pressing the support, and a clamping seat 1018. A transmission rod 1013 is installed at the output end of the drive cylinder 1011, the clamping arm 1017 is rotatably installed on the upper end of the transmission rod 1013, and the clamping seat 1018 is located below the clamping arm 1017.

[0036] A side clamping seat 1019, an auxiliary clamping seat 1020, and a support base 1021 are provided on the lower side of the clamping seat 1018. The auxiliary clamping seat 1020, the side clamping seat 1019, the clamping seat 1018, and the clamping arm 1017 form an inclined positioning specification. The support base 1021 is used for sliding guide support of the second side positioning mechanism 102 and the first side positioning mechanism 101.

[0037] Both the side positioning mechanism 101 and the side positioning mechanism 2 102 are equipped with pneumatic control components. The pneumatic control components include a pneumatic control component 1016 for pneumatic transmission support, a pressing plate 1015 for pressing control, and a fastening bolt 1014 for connecting support.

[0038] The fastening bolt 1014 is fixedly inserted with a fixing plate, which passes through the transmission rod 1013. The transmission rod 1013 slides through and is provided with a fixing seat 1012. The pneumatic control component 1016 is installed on the side of the fixing seat 1012, and the pressing plate 1015 is installed at the lower end of the fastening bolt 1014.

[0039] Driven by the drive cylinder 1011, the pneumatic control component 1016 is pressed, and with the assistance of the clamping seat 1018, the welding part 2 is clamped and positioned. With the side clamping seat 1019 and the auxiliary clamping seat 1020 clamping simultaneously, it is positioned with the same arc as the wheel cover, ensuring the accuracy of its positioning and connection, while ensuring the safety of the welding part 2 itself.

[0040] While the drive cylinder 1011 is running, the fixed base 1012 is fixed to the upper end of the drive cylinder 1011, and under the fixed support of the pneumatic control component 1016, the transmission rod 1013 drives the fixed plate and fastening bolt 1014 to move down synchronously, pushing the pressing piece 1015 to press the control switch on the pneumatic control component 1016, so that the side positioning mechanism 101 controls the pneumatic control component 1016 to run synchronously when clamping and positioning. At this time, the side positioning mechanism 2 102 is in a connected running state. Since the control of the pneumatic control component 1016 to run the side positioning mechanism 101, the side positioning mechanism 2 102 and the middle positioning mechanism 103 by pneumatics is the prior art, it is not described in detail in this embodiment.

[0041] By adjusting the nut on the fastening bolt 1014, the position of the fastening bolt 1014 can be adjusted synchronously, thereby adjusting the height of the pressing plate 1015. When the side positioning mechanism 101 and the side positioning mechanism 2 102 clamp and position the welded parts 2 of different thicknesses, the distance between the pressing plate 1015 and the pneumatic control component 1016 can be set according to their clamping and moving stroke. The operation of the pneumatic control component 1016 is synchronized and accurate with the clamping and positioning of the side positioning mechanism 101. By operating the side positioning mechanism 2 102 in the same way, the side positioning mechanism 101, the side positioning mechanism 2 102, and the central positioning mechanism 103 can operate stably and accurately respectively.

[0042] The central positioning mechanism 103 includes a control cylinder 1031 for driving support, a positioning support plate 1032 for fixing support, a clamping member 1033 for pressing and positioning, and a slide rail 1034 for guiding support. The positioning support plate 1032 is installed at the output end of the control cylinder 1031, the clamping member 1033 is installed at the upper end of the positioning support plate 1032, and there are at least two slide rails 1034, which are symmetrically installed at the lower end of the positioning support plate 1032 and are slidably connected to the lower end of the positioning support plate 1032.

[0043] Several hook cylinders 3 are provided on the welding table 1. The hook cylinders 3 are used for positioning and fastening of the welding parts 2.

[0044] When the pressing piece 1015 in the side positioning mechanism 102 presses the pneumatic control component 1016, the middle positioning mechanism 103 can operate with air supply. Under the synchronous operation of multiple clamping components 1033, the upper cylinder is activated, controlling the clamping part to position and clamp the welding part 2, ensuring that the middle front panel is accurately positioned, and finally making the device achieve an accurate positioning effect. Based on the insertion positioning of the hook cylinder 3 itself, the accurate and reliable positioning and clamping of the welding part 2 is further guaranteed. Since the specific clamping part on the clamping component 1033 and the automatic positioning part operation mode of the hook cylinder 3 are existing technologies, they are not described in detail in the embodiment.

[0045] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. Any method that can achieve its beneficial effect can be implemented. In addition, the electrical components in this embodiment are all electrically connected to the main controller and the power supply. The main controller can be a conventional known device such as a computer that plays a control role. Those skilled in the art can control the electrical components through simple programming. Moreover, the existing disclosed power connection technology is also common knowledge in the field. Therefore, the specific structural composition and working principle will not be described in detail in this embodiment.
