Description

Technical Field

[0001] This utility model relates to the field of resistance welding equipment technology, and in particular to a multi-station resistance welding equipment. Background Technology

[0002] Resistance welding machines are welding devices that use the principle of resistance heating for welding. Classified by welding method, they include spot welding machines, seam welding machines, projection welding machines, and butt welding machines.

[0003] Spot welding is a resistance welding method that assembles workpieces into lap joints and presses them between two electrodes, using resistance heat to melt the base metal to form weld points. Traditional multi-point spot welding between multiple metal layers is done manually on a single spot welding machine or with a handheld spot welding machine, with each weld point on the product being welded one by one. This results in poor welding consistency, inconsistent welding quality, low welding efficiency, and high labor intensity. Utility Model Content

[0004] The technical problem to be solved by this utility model is that spot welding is a resistance welding method that assembles the workpieces into a lap joint and presses them between two electrodes, using resistance heat to melt the base metal to form a weld point. Traditional multi-point spot welding between multiple layers of metal is done manually on a single spot welding machine or with a handheld spot welding machine, with poor welding consistency, inconsistent welding quality, low welding efficiency, and high labor intensity.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-station resistance welding equipment, including a resistance welding machine and a rotating frame. A driving device is provided between one side of the resistance welding machine and the rotating frame. A welding device is symmetrically and slidably installed on one side of the resistance welding machine. A material unloading device is provided on one side of the resistance welding machine. A clamping device is provided on one side of the resistance welding machine. Several fixed frames are installed through one side of the rotating frame. A tray rack is installed through the inner wall of the fixed frame. Several sliding holes are opened on one side of the tray rack. Several clamping blocks are rotatably installed on the inner wall of the fixed frame. The outer surface of one end of the clamping block is slidably installed in the inner wall of the sliding hole.

[0006] The aforementioned components achieve the following effect: When welding an object using a resistance welding machine, the object can be placed on the placement tray. Then, the drive device is activated, causing the rotating frame and several fixed frames to rotate. The fixed frames and placement tray containing the object to be welded rotate to a position below the welding device. During this revolution, the drive device also causes the placement tray to rotate within the inner wall of the fixed frames. Sliding on one side will cause the clamping block to slide on the outer surface of one end, squeezing the clamping block to rotate within the inner wall of the fixed frames, thus clamping and limiting the object placed on the placement tray. Once the object is rotated to a position below the welding device, it is locked, and then the welding device... The object is welded. After welding, the welded position is pressed by a clamping device to improve the weld's strength. Finally, the drive device is activated to rotate the rotating frame and rotate the welded object out. The objects on the next fixed frame and placement tray continue to rotate to the bottom of the welding device for welding. The welded object then rotates to the unloading device to be unloaded, making it easier to place the next object for welding. By alternately loading and unloading objects from several fixed frames and placement trays for welding, the consistency of welding quality can be effectively guaranteed, greatly improving production efficiency and reducing labor intensity.

[0007] Preferably, the driving device includes a first motor, wherein one side of the first motor is fixedly mounted on one side of the resistance welding machine, and the output end is fixedly connected to one side of the rotating frame via a coupling; a first hydraulic cylinder, wherein the outer surface of the first hydraulic cylinder is fixedly mounted on one side of the resistance welding machine; a second motor, wherein one side of the second motor is fixedly mounted on the output end side of the first hydraulic cylinder; a first gear, wherein one side of the first gear is fixedly mounted on the output end of the second motor via a coupling; and a second gear, wherein the inner wall of the second gear is sleeved on the outer surface of one end of the placement plate frame, and the outer surface meshes with the outer surface of the first gear.

[0008] The effect achieved by the above components is as follows: By setting up a drive device, after the object is placed, the first motor can be started to drive the rotating frame to rotate, thereby driving several fixed frames to revolve. Then, when the fixed frames and the placement tray frame rotate to a certain position, the first hydraulic cylinder is started to drive the second motor and the first gear to move upward to a certain position, so that the outer surface of the first gear meshes with the second gear on the placement tray frame. Then, the second motor is started to drive the first gear to rotate, thereby driving the second gear and the placement tray frame to rotate in the inner wall of the fixed frame. The sliding on one side will slide on the outer surface of one end of the clamping block, squeezing the clamping block to rotate in the inner wall of the fixed frame, clamping and limiting the object placed on the placement tray frame, so that it is not easy to shake during welding, thus improving the welding effect.

[0009] Preferably, both the first motor and the second motor are self-locking motors.

[0010] The effect achieved by the above components is that by setting the first motor and the second motor as self-locking motors, they can be self-locked and fixed after the rotating frame and the placement plate frame are rotated to a certain position. This makes it less likely for the welding to shake, thus improving the stability and effect of the welding.

[0011] Preferably, the welding device includes two mounting brackets, one side of which is slidably mounted on one side of the resistance welding machine, and the distance between the two mounting brackets is adjusted and fixed by a lead screw; a second hydraulic cylinder, one side of which is fixedly mounted on one side of the mounting bracket; and a resistance welding gun, one side of which is fixedly mounted on the output end of the second hydraulic cylinder.

[0012] The effect achieved by the above components is as follows: by setting up the welding device, during welding, the screw on the resistance welding machine can be rotated according to the welding requirements to adjust the distance between the two mounting brackets to the specified size, and then the second hydraulic cylinder is started to drive the resistance welding gun downward so that one end of the resistance welding gun abuts against one side of the object for welding.

[0013] Preferably, the clamping device includes a groove frame, wherein one side of the groove frame is fixedly mounted on one side of the resistance welding machine; a rotating rod, wherein both sides of the rotating rod are rotatably mounted on both sides of the inner wall of the groove frame; a pressure plate, wherein one end of the pressure plate is rotatably mounted in the inner wall of one end of the rotating rod; and a fifth hydraulic cylinder, wherein one side of the fifth hydraulic cylinder is fixedly mounted on one side of the resistance welding machine, and the output end is rotatably mounted in the inner wall of one end of the rotating rod.

[0014] The effect achieved by the above components is as follows: after the resistance welding gun welds the object, the output end of the fifth hydraulic cylinder can be activated to move upward, pushing one end of the rotating rod upward, causing it to rotate in the inner wall of the groove frame. Then the other end will drive the pressure plate to move downward to press the object tightly, making the weld joint more tightly joined and improving the welding effect.

[0015] Preferably, the unloading device includes an unloading frame, wherein one side of the unloading frame is fixedly installed on one side of the resistance welding machine, and a third hydraulic cylinder is rotatably installed on one side of the inner wall of the unloading frame; a guide plate, wherein one end of the guide plate is slidably installed in a slide rail on the unloading frame on both sides, and one side is rotatably installed on the output end of the third hydraulic cylinder; two fourth hydraulic cylinders, wherein one side of the two fourth hydraulic cylinders is symmetrically fixedly installed on one side of the unloading frame; and a top block, wherein one side of the top block is fixedly installed on the unloading frame on the output end of the fourth hydraulic cylinder located above the placement tray.

[0016] The effect achieved by the above components is as follows: By setting up the unloading device, when the fixed frame and the placement tray are rotated to the unloading frame, the output end of the fourth hydraulic cylinder located below the placement tray can be activated to penetrate the inner wall of the placement tray and lift the object. At the same time, the fourth hydraulic cylinder located above the placement tray drives the top block to move downward to clamp and fix the lifted object. Then, the third hydraulic cylinder is activated to drive the guide plate to slide to one end in the slide on the unloading frame until it is below the object. Then, the two fourth hydraulic cylinders are opened to place the object on the guide plate and unload it, thereby completing the welding process and facilitating subsequent processing. Finally, the fourth hydraulic cylinder is reset to allow the fixed frame and the placement tray to continue rotating and welding.

[0017] Preferably, a protective device is provided on one side of the resistance welding machine. The protective device includes a bracket, one side of which is fixedly installed on one side of the resistance welding machine; an electric telescopic rod, one side of which is fixedly installed on one side of the bracket; and a protective cover, one side of which is fixedly installed on the output end of the electric telescopic rod.

[0018] The effect achieved by the above-mentioned components is as follows: by setting up a protective device, when the welding device is welding an object, the electric telescopic rod on the bracket can be activated to drive the protective cover downward, thereby covering the outer surface of the fixed frame and the placement tray at the welding point, separating them from the two adjacent fixed frames. In this way, the welding slag generated during the welding process is less likely to splash onto the adjacent fixed frames and placement trays, avoiding affecting the welding of subsequent objects and improving the welding effect.

[0019] Preferably, a reinforcing rod is fixedly installed on the outer surface of the output end of the electric telescopic rod, and one side of the reinforcing rod is fixedly installed on one side of the protective cover.

[0020] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the output end of the electric telescopic rod and the protective cover can be increased, making the connection more secure and less prone to damage.

[0021] The beneficial effects of this utility model are:

[0022] When using a resistance welding machine to weld objects, the object is placed on the placement tray. The drive unit is then activated, rotating the rotating frame and several fixed frames. The fixed frames and placement tray containing the object are rotated to a position below the welding device. During this revolution, the drive unit also causes the placement tray to rotate within the inner wall of the fixed frames. A sliding contact on one side slides on the outer surface of one end of the clamping block, causing the clamping block to rotate within the inner wall of the fixed frames, thus clamping and limiting the object placed on the placement tray. Once the object is rotated to a position below the welding device, it is locked in place. The welding device then welds the object. After welding, the welding position is pressed by a clamping device to improve the weld's strength. Finally, the drive device is activated to rotate the rotating frame, rotating the welded object out. The objects on the next fixed frame and placement tray continue to rotate to the bottom of the welding device for welding. The welded object then rotates to the unloading device to be unloaded, making it easier to place the next object for welding. By alternating loading and unloading of several fixed frames and placement trays for welding, the consistency of welding quality can be effectively guaranteed, greatly improving production efficiency and reducing labor intensity.

A driving device 3 is provided between one side of the resistance welding machine 1 and the rotating frame 2. A welding device 4 is symmetrically and slidably installed on one side of the resistance welding machine 1. A material unloading device 5 is provided on one side of the resistance welding machine 1. A clamping device 6 is provided on one side of the resistance welding machine 1. Several fixed frames 8 are installed through one side of the rotating frame 2. A tray rack 9 is installed through the inner wall of the fixed frame 8. Several sliding holes 10 are opened on one side of the tray rack 9. Several clamping blocks 11 are rotatably installed on the inner wall of the fixed frame 8. One end of the clamping block 11 is slidably installed in the inner wall of the sliding hole 10. When using the resistance welding machine 1 to weld an object, the object can be placed on the placement tray 9. Then, the drive device 3 is started to drive the rotating frame 2 and several fixed frames 8 to rotate, rotating the fixed frames 8 and the placement tray 9 containing the object to be welded to the bottom of the welding device 4. During the revolution, the drive device 3 also drives the placement tray 9 to rotate on its own axis within the inner wall of the fixed frame 8. The sliding on one side will slide on the outer surface of one end of the clamping block 11, squeezing the clamping block 11 to rotate within the inner wall of the fixed frame 8, clamping and limiting the object placed on the placement tray 9. After it is rotated to the bottom of the welding device 4, it is locked, and then the welding device 4... The object is welded. After welding, the welding position is pressed by the clamping device 6 to improve the weld's strength. Finally, the drive device 3 is activated to rotate the rotating frame 2, rotating the welded object out. The object on the next fixed frame 8 and the placement tray 9 continues to rotate to the bottom of the welding device 4 for welding. The welded object then rotates to the unloading device 5 to be unloaded, making it easier to place the next object for welding. By alternately loading and unloading welding objects with several fixed frames 8 and placement trays 9, the consistency of welding quality can be effectively guaranteed, greatly improving production efficiency and reducing labor intensity.

[0036] Figure 1-8The drive device 3 shown includes a first motor 31, one side of which is fixedly mounted on one side of the resistance welding machine 1, and its output end is fixedly connected to one side of the rotating frame 2 via a coupling; a first hydraulic cylinder 32, the outer surface of which is fixedly mounted on one side of the resistance welding machine 1; a second motor 33, one side of which is fixedly mounted on one side of the output end of the first hydraulic cylinder 32; a first gear 34, one side of which is fixedly mounted on the output end of the second motor 33 via a coupling; and a second gear 35, the inner wall of which is sleeved on the outer surface of one end of the placement plate 9, and its outer surface meshes with the outer surface of the first gear 34. By setting the drive device 3, after the object is placed, the first motor 31 can be started to drive the rotating frame 2 to rotate, thereby driving several fixed frames 8 to revolve. Then, when the fixed frames 8 and the placement tray 9 rotate to a certain position, the first hydraulic cylinder 32 is started to drive the second motor 33 and the first gear 34 to move upward to a certain position, so that the outer surface of the first gear 34 meshes with the second gear 35 on the placement tray 9. Then, the second motor 33 is started to drive the first gear 34 to rotate, thereby driving the second gear 35 and the placement tray 9 to rotate in the inner wall of the fixed frame 8. The sliding on one side will slide on the outer surface of one end of the clamping block 11, squeezing the clamping block 11 to rotate in the inner wall of the fixed frame 8, clamping and limiting the object placed on the placement tray 9, so that it is not easy to shake during welding and improving the welding effect.

[0037] Figure 1-8 The first motor 31 and the second motor 33 shown are both self-locking motors. By setting the first motor 31 and the second motor 33 as self-locking motors, they can be self-locked and fixed after the rotating frame 2 and the placement plate frame 9 are rotated to a certain position. This prevents shaking during welding and improves the stability and effect of welding. The welding device 4 includes two mounting brackets 41, one side of which is slidably mounted on one side of the resistance welding machine 1, and the distance between the two mounting brackets 41 is adjusted and fixed by a screw; a second hydraulic cylinder 42, one side of which is fixedly mounted on one side of the mounting bracket 41; and a resistance welding gun, one side of which is fixedly mounted on the output end of the second hydraulic cylinder 42. By setting the welding device 4, during welding, the screw on the resistance welding machine 1 can be rotated to adjust the distance between the two mounting brackets 41 to the specified size according to the welding requirements. Then, the second hydraulic cylinder 42 is started to drive the resistance welding gun downward, so that one end of the resistance welding gun abuts against one side of the object for welding.

[0038] Figure 1-8The clamping device 6 shown includes a grooved frame 61, one side of which is fixedly mounted on one side of the resistance welding machine 1; a rotating rod 62, both sides of which are rotatably mounted on the inner wall of the grooved frame 61; a pressure plate 63, one end of which is rotatably mounted in the inner wall of one end of the rotating rod 62; and a fifth hydraulic cylinder 64, one side of which is fixedly mounted on one side of the resistance welding machine 1, and its output end is rotatably mounted in the inner wall of one end of the rotating rod 62. After the resistance welding gun has welded the object, the output end of the fifth hydraulic cylinder 64 can be activated to move upward, pushing one end of the rotating rod 62 upward, causing it to rotate within the inner wall of the grooved frame 61. Then, the other end will drive the pressure plate 63 downward to clamp the object, making the weld joint tighter and improving the welding effect. The unloading device 5 includes an unloading rack 51, one side of which is fixedly mounted on one side of the resistance welding machine 1, and a third hydraulic cylinder 52 is rotatably mounted on one side of the inner wall of the unloading rack 51; a guide plate 53, one end of which is slidably mounted on both sides in the slide rails on the unloading rack 51, and one side is rotatably mounted on the output end of the third hydraulic cylinder 52; two fourth hydraulic cylinders 54, one side of which is symmetrically fixedly mounted on one side of the unloading rack 51; and a top block 55, one side of which is fixedly mounted on the unloading rack 51 above the placement tray 9 on the output end of the fourth hydraulic cylinder 54. By setting up the unloading device 3, when the fixed frame 8 and the placement tray 9 are rotated to the unloading rack 51, the output end of the fourth hydraulic cylinder 54 located below the placement tray 9 can be activated to push the object through the inner wall of the placement tray 9. At the same time, the fourth hydraulic cylinder 54 located above the placement tray 9 drives the top block 55 to move downward to clamp and fix the lifted object. Then, the third hydraulic cylinder 52 is activated to drive the guide plate to slide to one end in the slide on the unloading rack 51 until it is below the object. Then, the two fourth hydraulic cylinders 54 are opened to place the object on the guide plate and then unload it, thereby completing the welding process and facilitating subsequent processing. Finally, the fourth hydraulic cylinder 54 is reset to allow the fixed frame 8 and the placement tray 9 to continue rotating and welding.

[0039] Figure 1-8The resistance welding machine 1 shown is equipped with a protective device 7 on one side. The protective device 7 includes a bracket 71, one side of which is fixedly installed on one side of the resistance welding machine 1; an electric telescopic rod 72, one side of which is fixedly installed on one side of the bracket 71; and a protective cover 73, one side of which is fixedly installed on the output end of the electric telescopic rod 72. By setting up the protective device 7, when the welding device 4 is welding an object, the electric telescopic rod 72 on the bracket 71 can be activated to drive the protective cover 73 downward, thereby covering the outer surface of the fixing frame 8 and the placement tray 9 at the welding point, separating them from the two adjacent fixing frames 8. In this way, the welding slag generated during the welding process is less likely to splash onto the adjacent fixing frames 8 and the placement tray 9, avoiding affecting the welding of subsequent objects and improving the welding effect. A reinforcing rod 74 is fixedly installed on the outer surface of the output end of the electric telescopic rod 72, one side of which is fixedly installed on one side of the protective cover 73. By setting up the reinforcing rod 74, the connection area between the output end of the electric telescopic rod 72 and the protective cover 73 can be increased, making the connection more secure and less prone to damage.

[0040] Working principle: When using the resistance welding machine 1 to weld an object, the object can be placed on the placement tray 9. Then, the drive device 3 is started to drive the rotating frame 2 and several fixed frames 8 to rotate, rotating the fixed frames 8 and the placement tray 9 containing the object to be welded to the bottom of the welding device 4. During the revolution, the drive device 3 also drives the placement tray 9 to rotate on its own axis within the inner wall of the fixed frame 8. The sliding on one side will slide on the outer surface of one end of the clamping block 11, squeezing the clamping block 11 to rotate within the inner wall of the fixed frame 8, clamping and limiting the object placed on the placement tray 9. After it is rotated to the bottom of the welding device 4, it is locked, and then the welding process begins. The welding device 4 is used to weld objects. After welding, the welding position is pressed by the clamping device 6 to improve the weld's strength. Finally, the drive device 3 is activated to rotate the rotating frame 2 and rotate the welded object out. The objects on the next fixed frame 8 and the placement tray 9 continue to rotate to the bottom of the welding device 4 for welding. The welded object is then rotated to the unloading device 5 to be unloaded, making it easier to place objects for welding later. By using several fixed frames 8 and placement trays 9 to alternately load and unload objects for welding, the consistency of welding quality can be effectively guaranteed, greatly improving production efficiency and reducing labor intensity.
