Content of the Utility Model

[0004] The purpose of the utility model is to provide a laser welding rotary indexing table to solve the problems raised in the background technique.

[0005] The embodiment of the present application provides a laser welding rotary indexing table, including a chassis. Above the chassis is provided a turntable.

An arc-shaped groove is opened at the top of the annular member. The lower end of the limiting shaft is located inside the arc-shaped groove, and the limiting shaft is adapted to the arc-shaped groove. The cross-section of the arc-shaped groove in a top view is in the shape of a major arc.

[0006] By adopting the above technical solution, the reduction motor and the rotating shaft can drive the turntable to rotate, so as to rotate the workpiece fixed on the workpiece placement plate to the laser welding processing position, and the limiting effect of the limiting shaft and the arc-shaped groove ensures that the rotation angle of the turntable is less than 360°, thereby preventing the power supply wires from getting entangled.

[0013] Optionally, a plurality of convex strips are fixedly connected to the adjacent sides of the two fixing members.

[0014] By adopting the above technical solution, the stability of clamping and fixing the workpiece is increased.

[0018] The technical solution of this application can drive the turntable to rotate through a reduction motor and a rotating shaft, so as to rotate the workpiece fixed on the workpiece placement plate to the laser welding processing position. And through the limiting effect of the limiting shaft and the arc groove, it is ensured that the rotation angle of the turntable is less than 360°, thereby preventing the power supply wire from being wound and increasing the safety of use.

[0019] The technical solution of this application sucks the dust generated during the laser welding process into the dust collection hood through a blower.

Detailed Embodiment

[0027] The following will clearly and completely describe the technical solutions in the embodiments of this application with reference to the accompanying drawings in the embodiments of this application. Obviously, the described embodiments are only a part of the embodiments of this application, rather than all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of this application. Embodiment 1

[0028] Please refer to Figure 1-2 For this utility model, a technical solution is provided: It includes a chassis 1. Above the chassis 1, there is a turntable 2. On the top of the turntable 2, several workpiece placement plates 3 are fixedly installed. At the bottom of the chassis 1, a reduction motor 4 is fixedly installed, and a rotating shaft 18 passes through the middle of the chassis 1. The lower end of the rotating shaft 18 is fixedly installed with the output end of the reduction motor 4, and the upper end of the rotating shaft 18 is fixedly installed with the bottom of the turntable 2. At the top of the chassis 1, an annular member 19 is fixedly installed. At the bottom of the turntable 2, a limiting shaft 20 is fixedly installed. An arc-shaped groove 21 is opened at the top of the annular member 19. The lower end of the limiting shaft 20 is inside the arc-shaped groove 21, and the limiting shaft 20 is adapted to the arc-shaped groove 21. The cross-section of the arc-shaped groove 21 in a top view is in the shape of a major arc;

[0029] In this technical solution, the turntable 2 can be driven to rotate through the reduction motor 4 and the rotating shaft 18, thereby driving the workpiece placement plate 3 to rotate, so as to rotate the workpiece fixed on the workpiece placement plate 3 to the laser welding processing position. And through the limiting effect of the limiting shaft 20 and the arc-shaped groove 21, it is ensured that the rotation angle of the turntable 2 is less than 360°, thereby preventing the power supply wires from getting entangled and increasing the safety of use.

[0030] In some technical solutions, as Figure 1 and Figure 3 shown, a dust removal box 5 is fixedly installed on the top of the turntable 2. A dust-proof cover 7 is fixedly connected to the top of the workpiece placement plate 3. Inside the dust-proof cover 7, a dust collection cover 12 is fixedly installed. And on one side of the dust-proof cover 7 close to the dust removal box 5, an air inlet pipe 8 passes through. One end of the air inlet pipe 8 is communicated with the dust collection cover 12, and the other end of the air inlet pipe 8 is communicated with the inside of the dust removal box 5. A matching box cover 6 is fixedly installed on the top of the dust removal box 5. A fan 9 is fixedly installed on the top of the box cover 6, and an exhaust pipe 10 passes through and is in interference fit connection with the box cover 6. The exhaust pipe 10 is pipe-connected to the air inlet end of the fan 9. A filter element plate 22 is fixedly installed at the bottom of the box cover 6, and the filter element plate 22 is adapted to the dust removal box 5.

[0031] During use, the dust generated during the laser welding process is sucked into the dust collection cover 12 through the fan 9. The dust then enters the dust removal box 5 through the air inlet pipe 8. The filter element plate 22 filters and blocks the dust. Finally, the air is discharged through the exhaust pipe 10 and the fan 9, playing a role in removing dust during the laser welding process and improving the working environment of workers.

[0032] In some technical solutions, as Figure 1 shown, an electromagnetic valve 11 is provided on the air inlet pipe 8.

[0033] During use, the electromagnetic valve 11 facilitates controlling whether the air inlet pipe 8 is a passage, thereby ensuring the dust removal operation at the position where laser welding is performed.

[0034] In some technical solutions, such as Figure 1 As shown, a double-headed hydraulic cylinder 13 is fixedly installed on the top of the workpiece placement plate 3, and fixing members 14 are symmetrically and slidably connected to both sides of the top of the workpiece placement plate 3. The output ends of both ends of the double-headed hydraulic cylinder 13 are fixedly installed with the two fixing members 14 respectively.

[0035] During use, the two fixing members 14 are driven by the double-headed hydraulic cylinder 13 to move towards each other, so as to clamp and fix the workpiece to be laser welded.

[0036] In some technical solutions, such as Figure 5 As shown, a plurality of ridges 25 are fixedly connected to the adjacent sides of the two fixing members 14.

[0037] During use, the stability of clamping and fixing the workpiece is increased by the ridges 25.

[0038] In some technical solutions, such as Figure 1 and Figure 4 As shown, four legs 15 are fixedly connected at equal intervals along the outer edge of the bottom of the chassis 1. Threaded grooves 23 are opened at the lower ends of the legs 15. Threaded shafts 16 that are matched are threadedly connected inside the threaded grooves 23. The lower ends of the threaded shafts 16 are fixedly connected with foot pads 17. Anti-slip patterns 24 are provided at the bottoms of the foot pads 17.

[0039] During use, the position of the threaded shaft 16 inside the threaded groove 23 is adjusted by rotating the threaded shaft 16, so as to adjust the height of each foot pad 17, so that the rotary indexing table is applicable to an uneven tabletop. Embodiment 2

[0040] Working principle: During use, place the rotary indexing table under the laser welding machine, rotate the threaded shaft 16 to adjust its position inside the threaded groove 23, so as to adjust the height of each foot pad 17, so that the rotary indexing table is applicable to an uneven tabletop. The two fixing members 14 are driven by the double-headed hydraulic cylinder 13 to move towards each other, so as to clamp and fix the workpiece to be laser welded. The turntable 2 can be driven to rotate by the reduction motor 4 and the rotating shaft 18, so as to drive the workpiece placement plate 3 to rotate, so as to rotate the workpiece fixed on the workpiece placement plate 3 to the laser welding processing position. And through the limiting effect of the limiting shaft 20 and the arc-shaped groove 21, it is ensured that the rotation angle of the turntable 2 is less than 360°, so as to prevent the power supply wires from being wound. The soot generated during the laser welding process is sucked into the dust collection hood 12 by the blower 9. The soot then enters the dust removal box 5 through the air inlet pipe 8. The filter element plate 22 filters and blocks the dust. Finally, the air is discharged through the exhaust pipe 10 and the blower 9, which plays a role in removing soot during the laser welding process and improves the working environment of the workers.
