[0022] Depend on Figure 1-Figure 7The present invention provides a semiconductor metal block plasma arc welding machine, comprising a fixed plate 1, a cylinder 11 being fixedly connected to one side of the fixed plate 1, a first telescopic rod 12 being extended from one end of the cylinder 11, a second telescopic rod 28 being slidably connected to the inner wall of the first telescopic rod 12, a third spring 35 being fixedly connected between the inner wall of the first telescopic rod 12 and the second telescopic rod 28, a fixed plate 13 being fixedly connected to one side of the second telescopic rod 28, a curved track frame 2 being fixedly connected to one side of the fixed plate 1, a first track frame 3 being fixedly connected to one side of the curved track frame 2 There is a second track frame 4, and the upper end of the arc-shaped track frame 2 is fixedly connected to the first blanking frame 5. The first blanking frame 5 is equipped with multiple groups of first workpieces 8. The arc-shaped track frame 2 is provided with a notched track groove 36. The arc-shaped track frame 2 is provided with a first workstation 37, a second workstation 38 and a third workstation 39 in clockwise order; when the cylinder 11 is started, it can drive the first telescopic rod 12 to retract, thereby driving the fixed plate 13 to move toward the cylinder 11 through the second telescopic rod 28. The third spring 35 can provide pulling force to the second telescopic rod 28. At the same time, when the fixed plate 13 cannot move, the third spring 35 can provide telescopic space.

[0023] A first push plate 14 is fixedly connected to one side of the fixed disk 13, and the first push plate 14 corresponds to the first track frame 3. The upper end of the first track frame 3 is fixedly connected to the second blanking frame 6, and multiple groups of second workpieces 9 are placed in the second blanking frame 6; a second push plate 15 is fixedly connected to one side of the fixed disk 13, and the second push plate 15 corresponds to the position of the second track frame 4. The upper end of the second track frame 4 is fixedly connected to the third blanking frame 7, and multiple groups of third workpieces 10 are placed in the third blanking frame 7; the fixed disk 13 can drive the first push plate 14 and the second push plate 15 when moving, so that the second workpiece 9 and the third workpiece 10 are inserted into the first workpiece 8.

[0024] The cylindrical outer surface of the cylinder 11 is fixedly connected with a rotating ring 17, a torsion spring 18 is fixedly connected between the rotating ring 17 and the fixed plate 1, a slider 29 is fixedly connected to the inner wall of the rotating ring 17, an arc groove 30 is provided on the cylindrical outer surface of the cylinder 11, and the slider 29 is slidably connected to the arc groove 30, the cylindrical outer surface of the rotating ring 17 is fixedly connected with a first fixed sleeve 19, a wedge block 20 is slidably connected in the first fixed sleeve 19, and the wedge block 20 slides with the notch track groove 36 The cylindrical outer surface of the rotating ring 17 is fixedly connected with a toggle rod 25, a first spring 21 is provided between the inner wall of the first fixed sleeve 19 and the wedge block 20, and the cylindrical outer surface of the first telescopic rod 12 is fixedly connected with an oblique insert 16; the first spring 21 can be retracted into the first fixed sleeve 19 when its inclined surface is blocked by the first workpiece 8 (when the rotating ring 17 rotates counterclockwise under the rebound force of the torsion spring 18); the cylindrical outer surface of the arc track frame 2 is fixedly connected with three sets of second The fixing sleeve 22 is connected with a sliding block 24 in a sliding manner in each group of the second fixing sleeve 22, and a second spring 23 is provided between the inner wall of the second fixing sleeve 22 and the sliding block 24; when the inclined surface of the oblique inserting plate 16 presses the toggle rod 25, the rotating ring 17 can be rotated through the inclined surface. At this time, the first fixing sleeve 19 slides in the arc groove 30. When the inclined surface of the oblique inserting plate 16 is separated from the toggle rod 25, the slider 29 just slides the entire distance in the arc groove 30 (the rotation angle of the rotating ring 17 is relatively large). The first workpiece 8 is just small enough to rotate by one station, and the oblique insert 16 will not block the first fixed sleeve 19). At this time, the rotating ring 17 drives the first workpiece 8 to rotate by one station through the first fixed sleeve 19 and the wedge block 20 (rotating from the first station 37 to the second station 38. During this process, the sliding block 24 is pressed and retracted into the second fixed sleeve 22. The width of the sliding block 24 is larger than the groove on the first workpiece 8. The groove on the first workpiece 8 will not jam the sliding block 24 during rotation).

[0025] A welding notch groove 31 is provided on the cylindrical outer surface of the arc-shaped track frame 2, and a mounting rod 26 is fixedly connected to one side of the fixed plate 13, and a plasma arc welding gun 27 is fixedly connected to one side of the mounting rod 26, and the position of the plasma arc welding gun 27 corresponds to the welding notch groove 31; the plasma arc welding gun 27 can weld the welding seam 34 at the third work station 39 (the second workpiece 9, the third workpiece 10, and the first workpiece 8 are welded together).

[0026] A first semicircular hole 32 is provided on the second workpiece 9, a second semicircular hole 33 is provided on the third workpiece 10, and a welding seam 34 is provided on the first workpiece 8; the first semicircular hole 32 and the second semicircular hole 33 can be combined into one hole, which solves the problem that the existing device is difficult to drill long holes (the existing drilling machine cannot process slender holes). On the one hand, the structure of the welding seam 34 on the first workpiece 8 facilitates the one-time welding of the first workpiece 8, the second workpiece 9 and the third workpiece 10, and on the other hand, the groove structure can prevent the high-temperature part from directly contacting the inner wall of the arc track frame 2 after welding.

[0027] by Figure 1 From the main perspective, during the specific operation, first, multiple groups of first workpieces 8 are added to the first blanking frame 5, multiple groups of second workpieces 9 are added to the second blanking frame 6, and multiple groups of third workpieces 10 are added to the third blanking frame 7. A first workpiece 8 falls into the arc track frame 2 (at the first station 37, the first workpiece 8 in the arc track frame 2 cannot slide under the obstruction of the sliding block 24), and a second workpiece 9 falls into the first track frame 3. The initial state is as follows. Figure 1 and Figure 2 As shown, the cylinder 11 is started, driving the first telescopic rod 12 to retract. At this time, the first push plate 14 pushes the second workpiece 9 in the first track frame 3 to insert into the first workpiece 8 at the first station 37. Similarly, the second push plate 15 pushes the third workpiece 10 to insert into the first workpiece 8 at the second station 38. When the second workpiece 9 is fully inserted into the first workpiece 8, the oblique insert plate 16 just contacts the toggle rod 25. At this time, the first push plate 14 cannot continue to push forward. As the first telescopic rod 12 continues to retract, the third spring 35 is stretched, and the inclined surface of the oblique insert plate 16 begins to press the toggle rod 25, causing the rotating ring 17 to rotate through the inclined surface. At this time, the first fixed sleeve 19 is in an arc shape. When the inclined surface of the oblique insert 16 separates from the toggle rod 25 (the rotation angle of the rotating ring 17 is small, which just drives the first workpiece 8 to rotate one station, and the oblique insert 16 will not block the first fixed sleeve 19), the slider 29 just slides the entire distance in the arc groove 30. At this time, the rotating ring 17 drives the first workpiece 8 to rotate one station through the first fixed sleeve 19 and the wedge block 20 (rotating from the first station 37 to the second station 38. During this process, the sliding block 24 is pressed and retracted into the second fixed sleeve 22. The width of the sliding block 24 is larger than the groove on the first workpiece 8. The groove on the first workpiece 8 will not get stuck with the sliding block 24 during rotation).

[0028] Then, the cylinder 11 controls the first telescopic rod 12 to extend and reset (the torsion spring 18 elastically drives the rotating ring 17 to rotate and reset, and the third spring 35 contracts to drive the fixed plate 13 to reset). When the plasma arc welding gun 27 passes through the welding notch 31, it is started to weld the welding seam 34 at the third work station 39. Repeating the above operation can continuously complete the assembly welding of the first workpiece 8, the second workpiece 9 and the third workpiece 10. The welded workpieces automatically slide out from under the arc track frame 2 and can be manually transferred.

[0029] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
