[0003] At present, most automatic flipping mechanisms use a rotating shaft to drive the clamping parts to flip. For example, Chinese patent publication number CN220592122U discloses an automatic flipping device for workpieces used in welding lathe processing, including a base, two sets of legs are provided at the bottom end of the base, and a protective frame is provided on one side of the top of the base. The above-mentioned public document not only achieves the purpose of flexible clamping of the workpiece, thereby reducing the phenomenon of clamping damage to the workpiece by the chuck, but also can slowly flip the workpiece to ensure the flipping accuracy of the workpiece, and can clamp and fix the workpiece by two sets of chucks, thereby reducing the phenomenon of the workpiece falling during the flipping process. However, when using this patent, it is impossible to adjust the angle of the workpiece in all directions, and thus the operation is not flexible enough during welding processing, and the processing effect is low. To this end, those skilled in the art provide a kind of automatic flipping mechanism for workpieces used in welding lathe processing to solve the problems raised in the above-mentioned background technology.

[0007] A rotating motor for driving the connecting rod to rotate is provided on the outer side wall of one group of the straight plates.

[0008] As a further technical solution of the present invention, the drive assembly includes a dual-axis motor fixedly installed between the two groups of slides and located in the middle position of the outer top of the base, and the output ends on both sides of the dual-axis motor are fixedly connected to a screw rod, and fixed blocks are threadedly sleeved on the outer circumferential surfaces of the two groups of screw rods, the outer tops of the two groups of fixed blocks are fixedly connected to the outer bottoms of the two groups of movable plates, and the two groups of fixed blocks are slidably connected to the outer top of the base.

[0009] As a further technical solution of the present invention, the limit assembly includes a fixing sleeve fixedly installed at one end corresponding to each other of the two groups of connecting rods, the outer tops of the two groups of fixing sleeves are symmetrically provided with through-type openings, and the inner side walls on both sides of the two groups of fixing sleeves are rotatably connected with a bidirectional threaded rod, one end of the bidirectional threaded rod extends to the outside of the fixing sleeve, and a knob is also fixedly installed on the outer peripheral surface of the bidirectional threaded rod.

[0010] As a further technical solution of the present invention, a clamping plate is threadedly sleeved inside the two groups of fixing sleeves and on the outer circumferential surfaces of both ends of the bidirectional threaded rod, and one end of the clamping plate extends along the opening to above the outer top of the fixing sleeve.

[0013] The utility model provides an automatic workpiece turning mechanism for welding lathe processing, which has the following beneficial effects compared with the prior art:

[0014] 1. An automatic workpiece flipping mechanism for welding lathe processing uses a rotating motor as a power source during processing. With the cooperation of a connecting rod, it drives the fixed sleeve to rotate, allowing the workpiece to be flipped 360 degrees. This solves the problem of being unable to adjust the workpiece 360 ​​degrees in all directions, facilitates welding processing at different positions of the workpiece, makes welding operations flexible and changeable, and is conducive to improving the work efficiency of welding processing.

[0015] 2. An automatic workpiece flipping mechanism for welding lathe processing drives the bidirectional threaded rod to rotate by turning the knob, which drives the clamping plates to move closer or farther away from each other, thereby limiting the clamping of workpieces of different sizes. This not only reduces the risk of workpieces falling during the flipping process, but also meets the clamping requirements of various workpieces, thereby improving the applicability of the mechanism.

[0021] See also Figure 1-3As shown, a workpiece automatic flipping mechanism for welding lathe processing includes a base 1, with slides 2 fixedly installed on both ends of the outer top of the base 1, and two sets of slides 2 are connected to movable plates 3 at both ends of the outer top through sliders 19. A driving assembly capable of synchronously driving the movable plates 3 to move back and forth is provided between the two sets of slides 2 and located in the middle position of the outer top of the base 1. The driving assembly includes a dual-axis motor 9 fixedly installed between the two sets of slides 2 and located in the middle position of the outer top of the base 1, and both output ends of the dual-axis motor 9 are fixedly connected to screw rods 10. Fixed blocks 11 are threadedly sleeved on the outer peripheral surfaces of the two sets of screw rods 10. The outer tops of the two sets of fixed blocks 11 are fixedly connected to the outer bottoms of the two sets of movable plates 3, and the two sets of fixed blocks 11 are slidably connected to the outer top of the base 1. Starting the dual-axis motor 9 drives the screw rod 10 to rotate, thereby causing the fixed block 11 to drive the movable plates 3 to move back and forth towards or away from each other, thereby being able to limit and clamp workpieces of different lengths.

[0022] The outer tops of the two groups of movable plates 3 are fixedly installed with limit seats 4, and the outer tops of the limit seats 4 are slidably connected to the straight plates 6 through the guide rods 5. The outer side walls of the two groups of straight plates 6 corresponding to each other are rotatably connected with connecting rods 7. One end of the two groups of connecting rods 7 is provided with a limit assembly for clamping the workpiece, and the limit assembly includes a fixed sleeve 12 fixedly installed at one end corresponding to each other of the two groups of connecting rods 7. The outer tops of the two groups of fixing sleeves 12 are symmetrically provided with through-type openings 13, and the inner side walls on both sides of the two groups of fixing sleeves 12 are rotatably connected with a two-way threaded rod 14, one end of the two-way threaded rod 14 extends to the outside of the fixing sleeve 12, and the outer peripheral surface of the two-way threaded rod 14 is also fixedly installed with a knob 15. A splint 16 is threadedly sleeved on the inner part of the fixed sleeve 12 and on the outer circumferential surface of both ends of the bidirectional threaded rod 14. One end of the splint 16 extends along the opening 13 to the top of the outer top of the fixed sleeve 12. A rotating motor 8 for driving the connecting rod 7 to rotate is provided on the outer side wall of one group of straight plates 6.

Secondly, by starting the automatic push rod 17, the straight plate 6 is driven to slide up and down along the guide rod 5 on the limit seat 4, and then the vertical precision adjustment of the workpiece is performed, thereby further improving the applicability of the mechanism.

[0023] The working principle of the utility model is as follows: by starting the automatic push rod 17, the straight plate 6 moves upward along the guide rod 5 and away from the limit seat 4, and then the dual-axis motor 9 is driven to drive the screw rod 10 to rotate, driving the movable plate 3 to move back and forth on the slide 2, which can not only perform horizontal and vertical precision adjustment on workpieces of different sizes, but also meet the clamping requirements of various workpieces.

[0024] Then place the workpiece to be welded on the clamping plate 16, and turn the knob 15 to rotate the bidirectional threaded rod 14, driving the clamping plate 16 to squeeze and limit the workpiece.

[0025] After clamping is completed, the rotating motor 8 is started to drive the connecting rod 7 to drive the fixed sleeve 12 to rotate, thereby driving the workpiece to perform 360-degree flip adjustment. At the same time, under the effect of mutual fit, the fixed sleeve 12 on the other side can also be driven to rotate synchronously, which is convenient for welding at different positions of the workpiece, making the welding operation flexible and changeable, which is conducive to improving the work efficiency of the welding process.
