[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.

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 and Figure 6 The non-standard automated welding machine positioning mechanism shown in this embodiment includes: a hollow shell 1; a long groove 2 is formed on the top of the hollow shell 1 near the rear side; a connecting block 6 is slidably connected to the inner cavity of the long groove 2; a clamping plate 7 is fixedly connected to the top of the connecting block 6; and a movable block 5 is fixedly connected to the bottom of the connecting block 6. An electric push rod 3 is fixedly connected between the outer wall of the movable block 5 and the inner wall of the hollow shell 1. Two long grooves 8 are formed on the top of the hollow shell 1 near the front side; connecting blocks 11 are slidably connected to the inner cavities of both long grooves 8. 1. A clamping plate 2 9 is fixedly connected to the top of each of the two connecting blocks 2 11, and a threaded sleeve 12 is fixedly connected to the bottom of each of the two connecting blocks 2 11. A servo motor 14 is fixedly connected to the outer wall of the shell 1. A screw 13 is fixedly connected to the output end of the servo motor 14. One end of the screw 13 passes through the outer wall of the shell 1 and the two threaded sleeves 12, and is threadedly connected to the inner wall of the two threaded sleeves 12. The screw 13 is rotatably connected to the outer wall of the shell 1. A top frame 16 is also fixedly connected to the top of the shell 1 near the edge. A through groove 17 is opened at the bottom of the top frame 16. A baffle 19 is slidably connected to the inner cavity of the through groove 17.

[0030] Specifically, the workpiece to be processed is first placed on top of the empty shell 1, and the electric push rod 3 and servo motor 14 are driven simultaneously. The electric push rod 3 pushes the movable block 5 to move, the movable block 5 drives the connecting block 6 to move, the connecting block 6 drives the clamping plate 7 to move, and at the same time the servo motor 14 drives the screw 13 to rotate. The screw 13 drives the two threaded sleeves 12 to move relative to each other, the two threaded sleeves 12 drive the two connecting blocks 11 to move, and the two connecting blocks 11 drive the corresponding clamping plates 9 to move respectively. The clamping plates 7 and 9 are used to position the workpiece against each other and cooperate with the baffle 19 so that the workpiece can be more stably installed on the empty shell 1. After the subsequent welding operation is completed, the baffle 19 is moved and the servo motor 14 drives the two clamping plates 9 to move in the opposite direction. Then the electric push rod 3 is driven to push the workpiece through the through groove 17 to realize the unloading operation.

[0031] In this embodiment, as Figures 1-6 As shown; a positioning block 21 is fixedly connected to the outer wall of the baffle 19, and a positioning shaft 23 is movably connected through the positioning block 21. Multiple positioning holes 25 are opened on the outer wall of the shell 1. One end of the positioning shaft 23 is inserted into the inner cavity of the corresponding positioning hole 25, and the other end of the positioning shaft 23 is fitted with an anti-slip sleeve 24.

[0032] Specifically, by inserting the positioning shaft 23 on the baffle 19 into the positioning hole 25 on the empty shell 1, the positioning between the baffle 19 and the empty shell 1 is achieved, and the positioning operation of the baffle 19 is further realized, so that the baffle 19 can provide a stable limiting effect on the workpiece. Subsequently, the positioning shaft 23 can be pulled out to release the fixation of the baffle 19, so that the position of the baffle 19 can be changed, making it convenient to remove the workpiece.

[0033] In this embodiment, as Figure 6 As shown; a handle 22 is also fixedly connected to the outer wall of the positioning block 21, and the handle 22 is cylindrical.

[0034] Specifically, the handle 22 allows for easy application of force to the baffle 19, thus controlling the baffle 19 to change position.

[0035] In this embodiment, as Figure 6 As shown; a limiting groove 20 is provided at the top of the baffle 19, and a limiting strip 18 is slidably connected to the inner cavity of the limiting groove 20. The limiting strip 18 is fixedly connected to the top of the inner wall of the through groove 17.

[0036] Specifically, the combination of the limiting groove 20 and the limiting strip 18 can limit the horizontal movement trajectory of the baffle 19 and improve the stability of the baffle 19 during movement.

[0037] In this embodiment, as Figures 1-4 As shown, anti-slip pads 10 are fixedly connected to the outer walls of the first clamp 7 and the two second clamps 9.

[0038] Specifically, by using the anti-slip pad 10, the friction between clamping plate 7 and clamping plate 9 and the outer wall of the workpiece can be increased, thereby improving the positioning effect.

[0039] In this embodiment, as Figures 2-5 As shown; two fixing rings 4 are fixedly installed on the electric actuator 3, and the two fixing rings 4 are fixedly connected to the inner wall of the empty shell 1 and the outer wall of the movable block 5 respectively.

[0040] Specifically, the installation strength between the electric actuator 3 and the movable block 5 and the inner wall of the hollow shell 1 is improved by the cooperation of the two fixed rings 4, thereby improving the stability of the electric actuator 3.

[0041] In this embodiment, as Figures 1-3 As shown; a fixing bracket 15 is fixedly connected to the outer wall of the servo motor 14, and the fixing bracket 15 is fixedly connected to the outer wall of the shell 1.

[0042] Specifically, by setting the fixing bracket 15, the installation strength between the servo motor 14 and the outer wall of the shell 1 can be improved, ensuring the stable performance of the servo motor 14 during subsequent operation.
