Description

Technical Field

[0001] The invention relates to the technical field of metal product processing, in particular to a metal product processing spot welding device with an anti-drift function. Background Art

[0002] With the vigorous development of the manufacturing industry, metal products are widely used in many fields such as construction, automobiles, electronics, aerospace, etc. From everyday metal furniture and kitchen utensils to high-end automobile bodies and aircraft parts, the types of metal products are becoming increasingly rich and the production scale is constantly expanding. This puts higher demands on the processing accuracy, production efficiency and quality stability of metal products.

[0003] Spot welding, as an efficient and commonly used metal connection process, plays a key role in the processing of metal products. It applies pressure through electrodes and uses the resistance heat generated by the current passing through the contact points of the welds to weld two or more metal parts together. Compared with other welding methods, spot welding has the advantages of fast welding speed, small deformation, and easy automation. It is especially suitable for connecting thin metal sheets and can meet the diverse welding needs of different metal products.

[0004] During the spot welding process, factors such as the pressure applied by the electrode, the electromagnetic force generated by the welding current, and the thermal deformation of the weldment itself may cause the weldment to shift during the welding process. Even if the initial positioning is accurate, these external forces may cause the position of the weldment to change, thereby affecting the position accuracy of the weld and the welding quality. For example, when welding some thin and less rigid metal products, a small external force may cause the weldment to shift significantly.

[0005] In conjunction with the above content, it should be noted that: Chinese patent application number CN2017101152611 discloses a spot welding device for riveting with a positioning function, which is provided with a longitudinal fixing rod and a transverse fixing rod. The longitudinal fixing rod and the transverse fixing rod can fix the welded workpiece to prevent the welded workpiece from shifting during the spot welding process;

[0006] In fact, when spot welding metal products, the same type of metal products are usually processed continuously over a period of time. However, the device mentioned in the above document has certain defects. On the one hand, it lacks an effective conveying and positioning mechanism for the metal products; on the other hand, during the spot welding process, the electrode and the weldment frequently contact and rub, causing the electrode material to gradually wear and produce metal debris; when the degree of wear reaches a certain level, these debris may fall off and mix into the spot welding area, thereby interfering with the spot welding placement of the subsequently fed metal products and affecting the processing accuracy.

DETAILED DESCRIPTION

[0032] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0033] Example 1: Please refer to Figure 1 - Figure 7 As shown, this embodiment is a metal product processing spot welding device with an anti-drift function, including a rotating wheel frame 1, a plurality of material delivery and matching frames 2 are arranged on the outer peripheral wall of the rotating wheel frame 1, a limiting frame sleeve 4 is arranged on the top of the material delivery and matching frame 2, and an adjustable docking clamping mechanism 5 is sleeved on the top of the limiting frame sleeve 4. The adjustable docking clamping mechanism 5 includes a connecting arm 501 and a limiting middle cylinder 504. A plurality of groups of limiting claws 503 are arranged in a circular array on the outer wall of the connecting arm 501, and an internal pressure rod 507 is slidably sleeved inside the limiting middle cylinder 504.

[0034] The bottom of the material delivery and coordination frame 2 is provided with multiple groups of positioning cylinder frames 202 that pass through the reinforcing rib frame 101, and the top center of the material delivery and coordination frame 2 is provided with a middle adjustment cylinder frame 201, and the top of the middle adjustment cylinder frame 201 is sleeved with a sliding sleeve frame 203, and the sliding sleeve frame 203 is clamped with the clamping sleeve 401; when the rod-shaped metal product waiting to be processed is transported close to the loading area of the spot welding device, the positioning cylinder frame 202 drives the material delivery and coordination frame 2 to extend outward as a whole until the material delivery and coordination frame 2 is close to the rod-shaped metal product, and waits for the limit frame sleeve 4 to cooperate with the adjustable docking clamping mechanism 5 to clamp the rod-shaped metal product to a limited position, and then the positioning cylinder frame 202 is reset, thereby driving the clamped rod-shaped metal product into the spot welding device.

[0035] When the limiting frame sleeve 4 carries the adjustable docking clamping mechanism 5 close to the two ends of the rod-shaped metal product, the center adjustment cylinder frame 201 drives multiple groups of limiting frame sleeves 4 to slide toward the center, causing the adjustable docking clamping mechanism 5 to connect the two ends of the rod-shaped metal product and press and clamp it to achieve the loading and clamping of the rod-shaped metal product. Then the adjusting cylinder frame 202 drives the material delivery and coordination frame 2 to reset, and the rotating wheel frame 1 drives the group of material delivery and coordination frames 2 to rotate, and finally stops below the spot welding robot arm 307.

[0036] A plurality of reinforcing rib frames 101 are provided on the outer peripheral wall of the rotating wheel frame 1, a plate cylinder cover 106 is sleeved on the outer wall of the central axis 103, and a partition plate 102 fixedly connected to the inner wall of the rotating wheel frame 1 is provided on the outer wall of the plate cylinder cover 106, and a servo motor 104 is provided at one end of the central axis 103; the rotating wheel frame 1 is connected to the servo motor 104 through the central axis 103, and the servo motor 104 is connected to the central axis 103 through a coupling, and drives the rotating wheel frame 1 to rotate clockwise, rotating the material delivery and matching frame 2 holding the rod-shaped metal product on one side of the spot welding device upward until the material delivery and matching frame 2 is located at the twelve o'clock direction and stops.

[0037] Each two groups of partition plates 102 are symmetrically positioned on both sides of a group of reinforcing ribs 101, and a flip plate 105 is provided on the edge of the panel surface of a group of partition plates 102 on the same side of the reinforcing ribs 101, and a micro-rotating motor is provided at the hinge of the flip plate 105 and the partition plate 102; after waiting for the spot welding processing of the rod-shaped metal products on the single group of material delivery and matching racks 2 to be completed, the rotating wheel rack 1 drives the group of material delivery and matching racks 2 to rotate clockwise again, and when it rotates to the four o'clock direction, the debris generated by the spot welding processing is affected by the material delivery and matching racks. Under the influence of the synchronous rotation and tilting of the combining frame 2 and the partition plate 102, the debris gathered on the material delivery and matching frame 2 falls onto the inner wall of the partition plate 102, and is affected by the downward rotation of the partition plate 102, causing all of them to gather between the partition plate 102 and the flip plate 105, waiting for the rotating wheel frame 1 to complete unloading and then rotate further until the group of material delivery and matching frames is located at the six o'clock direction, at which time the micro-rotating motor drives the flip plate 105 to rotate, causing the debris accumulated between the partition plate 102 and the flip plate 105 to fall.

[0038] When the material delivery and coordination rack 2 approaches, the positioning cylinder rack 202 drives the material delivery and coordination rack 2 to extend outward, so that it is close to the external unloading equipment. During the regional coordination and connection, the center adjustment cylinder rack 201 drives the limit rack sleeve 4 and the adjustable docking clamping mechanism 5 to reset synchronously, and releases the clamping of the rod-shaped metal product, thereby realizing the continuous steps of loading, spot welding and unloading of the rod-shaped metal product. When this group of material delivery and coordination racks 2 rotates toward the spot welding robot arm 307 area, another group of material delivery and coordination racks 2 connected to it takes over and approaches the loading area, thereby forming a rotary continuous spot welding processing process. Holes facing the partition plate 102 are opened through the bottom of both sides of the material delivery and coordination rack 2.

[0039] A clamping sleeve 401 is provided at one end of the limiting sleeve 4 facing the welding support frame 3, and a grabbing plate rotating cylinder 402 is provided at one end of the limiting sleeve 4 away from the welding support frame 3. The end face of the grabbing plate rotating cylinder 402 is provided with a docking sleeve 403 connected to the adjustable docking clamping mechanism 5.

[0040] When the limiting sleeve is adjusted to be close to the rod-shaped metal product, the limiting middle cylinder 504 is aligned with the two ends of the rod-shaped metal product, and under the coordinated operation of the limiting sleeve and the material delivery coordination frame 2, the limiting middle cylinder 504 is close to the rod-shaped metal product, and the two ends of the rod-shaped metal product first contact the inner pressure rod 507, and push the inner pressure rod 507 to compress the spring rod, causing the inner pressure rod 507 to slide along the inside of the limiting middle cylinder 504.

[0041] One end of the connecting arm 501 is inserted into the docking sleeve 403, and a plurality of claw shafts 502 are arranged in a circular array on the end face of the connecting arm 501. The limiting claw 503 is sleeved inside the claw shaft 502, and an annular tooth groove is provided on the outer wall of one end of the limiting claw 503 facing the connecting arm 501.

[0042] A plurality of inflatable airbag cushions 505 are arranged in a circular array on the inner wall of the limiting middle tube 504, and a spring rod is provided in the inner center of the limiting middle tube 504 and is sleeved with the inner pressure rod 507. One end of the limiting middle tube 504 is inserted into the inner center of the connecting arm rod 501, and a plurality of rectangular tooth grooves are recessed on the outer wall of the middle rod body of the inner pressure rod 507. A connecting shaft 506 is sleeved through the inside of the connecting arm rod 501, and matching teeth are provided on the upper and lower shaft bodies of the connecting shaft 506 for meshing and transmitting with the rectangular tooth grooves and annular tooth grooves.

[0043] During the period when the rod-shaped metal product contacts and squeezes the inner pressure rod 507, the inflatable airbag cushion 505 continues to inflate, and the process is proportional to the speed at which the rod-shaped metal product enters the limiting middle cylinder 504. Therefore, when the rod-shaped metal product pushes the inner pressure rod 507 to compress the spring rod to the maximum limit, the inflatable airbag cushion 505 clamps and locks the rod-shaped metal product.

[0044] When the inner pressure rod 507 is pushed and moved, the inner pressure rod 507 is meshed with the connecting shaft 506 through the rectangular tooth groove and the adapter tooth part, causing the connecting shaft 506 to rotate. The connecting shaft 506 is meshed with the annular tooth groove through the adapter tooth part, thus forming a worm gear transmission structure, which is adjusted according to actual needs and is not limited to the graphic display. The limiting claw 503 is driven to run, and the hinge point of the limiting claw 503 and the claw shaft 502 rotates, causing multiple groups of limiting claws 503 to move toward the center synchronously, pushing the rod-shaped metal product toward the center, so that it remains in the middle of the two groups of limiting middle cylinders 504. Accordingly, when the limiting sleeve is loose and reset, under the influence of the phase extrusion pressure of the two groups of adjustable docking clamping mechanisms 5 and the peripheral pushing force of the rod-shaped metal product, the position displacement of the rod-shaped metal product caused by spot welding is eliminated.

[0045] During the spot welding process of the rod-shaped metal product, the grab plate rotary cylinder 402 drives the adjustable docking clamping mechanism 5 to rotate, thereby cooperating with the spot welding equipment on the spot welding robot arm 307 to perform spot welding processing on the rod-shaped metal product. The electric welding equipment is replaced according to the processing needs and connected and installed with the spot welding robot arm 307.

[0046] Embodiment 2: This embodiment is a metal product processing spot welding device with anti-drift function, including a central axis 103 provided in the middle of a rotating wheel frame 1, welding support frames 3 are sleeved on the outer walls of the shaft bodies at both ends of the central axis 103, a sliding beam 305 is provided on the top of the welding support frame 3, and a spot welding robot arm 307 facing the material delivery and coordination frame 2 is provided at the bottom of the sliding beam 305.

[0047] A support kit 302 is provided at the bottom of both ends of the welding support frame 3, an inclined support frame 301 is provided on the middle frame on the same side of the welding support frame 3, and an arc guide frame 303 is provided on the top of the welding support frame 3; the top of the arc guide frame 303 is slidably sleeved with a drive motor 1 304, the two ends of the sliding beam 305 are connected to the bottom of the drive motor, the top of the sliding beam 305 is slidably sleeved with a drive motor 2 306, and the bottom of the drive motor 2 306 is connected to the spot welding robot arm 307.

[0048] The welding support frame 3 is connected to the outer wall of the shaft body at both ends of the central axis 103 through the support kit 302, and the bottom of the support kit 302 is provided with a matching piece connected to the external mounting bracket, and then connected to the external unloading equipment through the inclined support frame 301, which can be used to assist the spot welding device and the external unloading equipment to connect and cooperate with each other, and can constitute a multi-point support installation for the welding support frame 3.

[0049] A roller 1 connected to the arc guide frame 303 is provided at the bottom of the driving motor 304, and fasteners connected to the sliding beam 305 are provided on both sides of the bottom of the driving motor 304, thereby driving the sliding beam 305 to move axially along the arc guide frame 303, so as to adjust the positional relationship between the welding machine and the rod-shaped metal product.

[0050] A roller 2 connected to the sliding beam 305 is provided at the bottom of the driving motor 2 306, and metal parts connected to the spot welding robot arm 307 are provided at both ends of the bottom of the driving motor 2 306, thereby driving the spot welding robot arm 307 to move axially below the sliding beam 305. The spot welding robot arm 307 is not limited to what is shown in the accompanying drawings. Accordingly, the appropriate spot welding robot arm 307 can be replaced according to the needs of spot welding processing, and is used for multi-angle spot welding processing of rod-shaped metal products.

[0051] Combining Examples 1 and 2, when a rod-shaped metal product awaiting processing approaches the loading area of the spot welding device, the positioning cylinder frame 202 drives the material delivery and coordination frame 2 closer. After the limiting frame sleeve 4 cooperates with the adjustable docking clamping mechanism 5 to clamp the product, the positioning cylinder frame 202 resets and feeds the product into the spot welding device. The intermediate adjustment cylinder frame 201 brings the limiting frame sleeve 4 closer, further stabilizing the clamping.

[0052] The rotating wheel frame 1 is driven by the servo motor 104, which drives the material delivery and coordination frame 2 to rotate, completing the continuous process of loading, processing and unloading; during processing, the grabbing plate rotary cylinder 402 drives the clamping mechanism to rotate to cooperate with spot welding. The device can also automatically clean up debris, and adjust the position of the electric welder and spot welding robot arm 307 by driving the motor to achieve multi-angle spot welding. The welding support frame 3 ensures stable operation of the equipment.
