Technical Field

[0001] The present invention relates to the field of welding technology, and more particularly to a laser welding device for potato processing metal parts. Background Art

[0002] Laser welding is an efficient and precise welding method that uses a high-energy-density laser beam as a heat source. Laser welding is one of the important aspects of the application of laser material processing technology. The existing laser welding devices for processing metal parts can only play a welding role, but cannot realize the automatic conversion of workstations, spray welding oil on the welds, and polish the welds after welding. Summary of the invention

[0003] In order to overcome the above-mentioned defects of the prior art, an embodiment of the present invention provides a laser welding device for potato-processed metal parts. The technical problem to be solved by the present invention is that the existing laser welding device for potato-processed metal parts can only play a welding role, but cannot realize automatic conversion of workstations, spray welding oil on welds, and polish welds after welding.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a laser welding device for potato processing metal parts, comprising a base plate, the upper end of the base plate is rotatably connected to a rotating ring, a workpiece is placed on the upper end of the rotating ring, the middle part of the workpiece is an arc-shaped protrusion, and multiple groups of welds are arranged on the workpiece, the upper end of the base plate is fixedly connected to a support plate, one side of the support plate is provided with a movable mechanism, and the upper end of the base plate is fixedly connected to a preheating machine;

[0005] The movable mechanism includes a collar, and the collar is fixedly connected to the support plate, a circular fixed frame is slidably connected inside the collar, a plurality of through-hole grooves are arranged on the circular fixed frame, a limiting rod is penetrated and connected with the circular fixed frame, a first motor is fixedly connected to one side of the support plate, a fixed shaft is extended to one end of the first motor, a rotating block is fixedly connected to one end of the fixed shaft, and the rotating block is located in the circular fixed frame, two groups of limiting grooves are arranged on the rotating block, and the limiting rod is slidably connected to the limiting groove, a fixing strip is fixedly connected to the cylindrical outer surface of the collar, an extension block is fixedly connected to one side of the fixing strip, a limiting track is arranged between the extension block and the collar, the limiting track is divided into abcd sections, and the limiting rod is slidably connected to the limiting track.

[0006] In a preferred embodiment, a telescopic rod is fixedly connected to the lower end of the circular fixed frame, a second rack is provided at the lower end of the telescopic rod, a second motor is fixedly connected to the cylindrical outer surface of the telescopic rod, a motor shaft is extended at one end of the second motor, a grinding head is fixedly connected to one end of the motor shaft, a welding gun is fixedly connected to the cylindrical outer surface of the telescopic rod, a small pump is fixedly connected to the upper end of the welding gun, and an oil supply pipe is connected to one end of the small pump.

[0007] In a preferred embodiment, a first rack is provided on the inner wall of the rotating ring, and the first rack is meshed with the second rack. A plurality of groups of first magnets are fixedly connected to the cylindrical outer surface of the rotating ring. A strong magnet is fixedly connected to the upper end of the base plate, and the strong magnet corresponds to the position of the first magnet.

[0008] Technical effects and advantages of the present invention:

[0009] After the first motor is started, it can drive the rotating block to rotate through the fixed shaft, thereby driving the limiting rod to move through the limiting groove. Due to the limitation of the limiting track, the limiting rod can only slide in the limiting track;

[0010] When the limit rod slides in the ab section, the circular fixed frame descends, and the small pump starts to spray welding oil on the weld. When the welding gun reaches point b, the circular fixed frame descends to the limit, the second rack meshes with the first rack, and the second motor starts at the same time, so that the grinding head grinds the welds of the previous group of welds;

[0011] When the limit rod slides in the bc section, the circular fixed frame rotates clockwise, and the second rack cooperates with the first rack to drive the rotating ring to rotate one station. At this time, since the small pump is also rotating, the small pump is still facing the weld sprayed with welding oil;

[0012] When the limit rod slides in the cd section, the circular fixed frame slides upward, the second rack is separated from the first rack, the welding gun is started, and the weld seam sprayed with welding oil is welded;

[0013] When the limit rod slides in section da, the circular fixed frame rotates counterclockwise, and the grinding head rotates toward the welded weld, and the small pump rotates toward the next set of welds.

[0014] Since the movement of the circular fixed frame is driven by the rotation of the rotating block, the circular fixed frame moves slowly in the middle and quickly at both ends in the four processes of ab, bc, cd, and da. During the welding process, the middle part of the weld can have a longer welding time and better weld the middle part of the weld (since the middle part of the workpiece is fatter, the depth of the weld from bottom to top is from shallow to deep and then to shallow, and the middle part requires more welding time). The entire device completes automatic welding oil spraying of the workpiece weld, automatic station switching, automatic welding, and automatic grinding and deburring.

[0026] The movable mechanism 5 includes a collar 11, and the collar 11 is fixedly connected to the support plate 8, a circular fixed frame 10 is slidably connected in the collar 11, and a plurality of through-hole grooves 23 are arranged on the circular fixed frame 10 (the through-hole grooves 23 can provide space for the relative movement of the fixed shaft 24 when the circular fixed frame 10 rotates), and a limiting rod 19 is connected through the circular fixed frame 10, a first motor 9 is fixedly connected to one side of the support plate 8, a fixed shaft 24 is extended to one end of the first motor 9, a rotating block 25 is fixedly connected to one end of the fixed shaft 24, and the rotating block 25 is located in the circular fixed frame 10, and two groups of limiting grooves 26 are arranged on the rotating block 25, and the limiting rod 19 is slidably connected with the limiting groove 26, the cylindrical outer surface of the ring 11 is fixedly connected with a fixing bar 20, one side of the fixing bar 20 is fixedly connected with an extension block 21, a limiting track 22 is arranged between the extension block 21 and the ring 11, the limiting track 22 is divided into abcd sections, and the limiting rod 19 is slidably connected with the limiting track 22; after the first motor 9 is started, it can drive the rotating block 25 to rotate through the fixed shaft 24, thereby driving the limiting rod 19 to move through the limiting groove 26, and due to the limitation of the limiting track 22, the limiting rod 19 can only slide in the limiting track 22; when the limiting rod 19 slides in the ab section, the circular fixed frame 10 descends, so as to Figure 6 As a reference, when the limit rod 19 slides in the bc section, the circular fixed frame 10 rotates clockwise (with Figure 1 As a reference), when the limiting rod 19 slides in the cd section, the circular fixed frame 10 slides upward, and when the limiting rod 19 slides in the da section, the circular fixed frame 10 rotates counterclockwise.

[0027] A telescopic rod 13 is fixedly connected to the lower end of the circular fixed frame 10, a second rack 14 is provided at the lower end of the telescopic rod 13, a second motor 15 is fixedly connected to the cylindrical outer surface of the telescopic rod 13, a motor shaft is extended at one end of the second motor 15, a grinding head 16 is fixedly connected to one end of the motor shaft, a welding gun 17 is fixedly connected to the cylindrical outer surface of the telescopic rod 13, a small pump 18 is fixedly connected to the upper end of the welding gun 17, and an oil supply pipe (not shown in the figure, used to provide welding oil) is connected to one end of the small pump 18.

[0028] A first rack 12 is provided on the inner wall of the swivel 2, and the first rack 12 is meshed with the second rack 14. A plurality of groups of first magnets 3 are fixedly connected to the cylindrical outer surface of the swivel 2. A strong magnet 4 (should be a strong magnet 4) is fixedly connected to the upper end of the base plate 1, and the position of the strong magnet 4 corresponds to that of the first magnet 3. The strong magnet 4 can absorb the first magnet 3 to prevent the swivel 2 from rotating autonomously due to interference from other external reasons.

[0029] During the specific operation, firstly, the workpiece 6 is mounted on the rotating ring 2, and the first motor 9 is started. The first motor 9 can drive the rotating block 25 to rotate through the fixed shaft 24, thereby driving the limiting rod 19 to move through the limiting groove 26. When the limiting rod 19 slides in the ab section, the circular fixed frame 10 descends. At this time, the small pump 18 is started to spray welding oil on the weld 7. When the welding gun 17 reaches point b, the circular fixed frame 10 descends to the limit, the second rack 14 is meshed with the first rack 12, and the second motor 15 is started at the same time, so that the grinding head 16 grinds the weld 7 of the previous group of welds. When the limiting rod 19 slides in the ab section, the circular fixed frame 10 descends. At this time, the small pump 18 is started to spray welding oil on the weld 7. When the welding gun 17 reaches point b, the circular fixed frame 10 descends to the limit, and the second rack 14 is meshed with the first rack 12. At the same time, the second motor 15 is started to make the grinding head 16 grind the weld 7 of the previous group of welds. When 19 slides in the bc section, the circular fixed frame 10 rotates clockwise, and the second rack 14 cooperates with the first rack 12 to drive the rotating ring 2 to rotate one station. At this time, since the small pump 18 is also rotating, the small pump 18 still faces the weld 7 sprayed with welding oil. When the limit rod 19 slides in the cd section, the circular fixed frame 10 slides upward, the second rack 14 is separated from the first rack 12 (at this time, the strong magnet 4 absorbs the first magnet 3 to achieve the station positioning of the rotating ring 2, and the position of the weld 7 corresponds to the position of the first magnet 3), and the welding gun 17 is started to weld the weld 7 sprayed with welding oil. When the limit rod 19 slides in the da section, the circular fixed frame 10 rotates counterclockwise, and the grinding head 16 rotates to face the welded weld 7, and the small pump 18 rotates to face the next group of welds 7, so as to complete the welding of multiple groups of welds 7 on the workpiece 6 in a cycle, change the station, spray welding oil and grind the weld 7. It should be noted that: when the limit rod 19 slides between the ab segment and the cd segment, the limit rod 19 performs a circular motion with a radius change around the axis of the fixed shaft 24, and the radius length specifically changes from large to small and then to large, the minimum radius length is when the limit rod 19 is at the midpoint of the ab segment and the cd segment, and the maximum radius length is when the limit rod 19 is at both ends of the ab segment and the cd segment. During normal welding, since the first motor 9 rotates at a uniform speed, when the limit rod 19 slides between the ab segment and the cd segment, its sliding speed changes from fast to slow and then to fast, and the slowest sliding speed is located at the midpoint of the ab segment and the cd segment. Since the movement of the welding gun 17 and the small pump 18 are synchronized with the movement of the limit rod 19, the welding gun 17 and the small pump 18 can realize multi-time slow welding of the arc-shaped convex part in the middle of the workpiece 6 (since the middle part of the workpiece 6 is an arc-shaped convex, the welding depth is large, and the welding time required is more), thereby ensuring the welding quality, and the circular fixed frame 10 is made of alloy steel.

[0030] Finally: The above description is only a preferred embodiment of the present invention and is 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 protection scope of the present invention.
