Description

Technical Field

[0001] This utility model relates to the field of iron bed welding robot technology, and in particular to a highly flexible iron bed welding robot. Background Technology

[0002] Welding robots are industrial robots that perform welding (including cutting and spraying). According to the definition of industrial robots belonging to the standard welding robots of the International Organization for Standardization (ISO), traditional welding robots have a clamping structure to fix the workpiece, which facilitates welding.

[0003] Common iron bed welding robots only include clamping functions, which can clamp workpieces, but lack the ability to freely switch between clamping and clamping functions. This cannot guarantee the flexibility of the welding robot, and the shape of the clamp is often fixed, resulting in the robot being able to clamp only workpieces with a single shape, which affects the flexibility of the welding robot.

[0004] Therefore, given that the aforementioned iron bed welding robot lacks a rapid switching function, which limits the types of workpieces it can be used for and severely restricts the flexibility of welding operations, there is an urgent need to design a new type of iron bed welding robot with high flexibility. Utility Model Content

[0005] To overcome the problem that common iron bed welding robots lack the ability to quickly switch between different types of workpieces, which limits their applicability and severely restricts the flexibility of welding operations.

[0006] The technical solution of this utility model is as follows: a highly flexible iron bed welding robot, including a supporting base plate; it also includes an mounting plate, a limiting frame, a clamping plate, a reset hole, an outlet hole, an L-shaped plate, a fixing plate, a cylinder, a connecting plate, and limiting pins. Two mounting plates are symmetrically arranged on the left and right sides of the top of the supporting base plate. A limiting frame is symmetrically arranged on the top of the two mounting plates. Four clamping plates are stacked inside the limiting frame. Two reset holes are opened through the front and rear sides of the top of the four clamping plates. Two outlet holes are opened through the front and rear sides of the top of the four clamping plates corresponding to the positions of the reset holes. An L-shaped plate is arranged on the rear side of the limiting frame. A fixing plate is connected to the top of the L-shaped plate. A cylinder is arranged on the top of the fixing plate. The output end of the cylinder at the bottom is connected to the connecting plate through the fixing plate. Two limiting pins are arranged on the front and rear sides of the bottom of the connecting plate.

[0007] Preferably, the clamping plate matching the workpiece shape is pushed outward of the limiting frame by slotting until the side of the clamping plate with the locking groove is completely moved outside the limiting frame, while the other three clamping plates remain inside the limiting frame. Then, the connecting plate is driven downward by a cylinder, and the connecting plate drives the limiting pin downward until the limiting pin is inserted into the reset hole of the clamping plate that has been moved out and the exit hole of the clamping plate that has not been moved out, thereby fixing the position of the clamping plate that has been moved out and the position that has not been moved out, realizing the function of free switching. This solves the problem that common iron bed welding robots only have the function of clamping, which can clamp the workpiece, but lack the function of free switching, which cannot guarantee the flexibility of the welding robot. The shape of the clamp is fixed, which can only clamp the workpiece with a single shape, thus affecting the flexibility of the welding robot.

[0008] Preferably, a slot is provided in the middle of one side of the limiting frame, and four different shaped slots are provided on the side of the four clamping plates away from the slot.

[0009] Preferably, two limiting plates are provided on the side of the slot at both ends of the clamping plate, and two sliders are provided on the front and back sides of the bottom of the mounting plate.

[0010] Preferably, two T-shaped slide rails are provided on the front and rear sides of the top of the support base plate, corresponding to the positions of the sliders, and the sliders are slidably connected to the T-shaped slide rails.

[0011] Preferably, a left side plate is provided on the left side of the top of the support base plate, and a right side plate is provided on the right side of the top of the support base plate.

[0012] Preferably, a motor is installed on the right side of the right side plate, and the output end of the motor on the left side is connected to a bidirectional lead screw through the right side plate.

[0013] Preferably, the left end of the bidirectional lead screw is rotatably connected to the right side of the left side plate, and a drive block is provided on the front side of both mounting plates, with the bidirectional lead screw threadedly connected to the two drive blocks.

[0014] The beneficial effects of this utility model are:

[0015] 1. By slotting, the clamping plate matching the shape of the workpiece is pushed outward from the limiting frame until the side of the clamping plate with the locking groove is completely separated from the limiting frame area, while the other three clamping plates remain in the positioning state inside the limiting frame. Then, the connecting plate is moved down vertically by the cylinder, and the linkage limiting pin moves down synchronously. Finally, the limiting pin accurately passes through the reset hole of the moved clamping plate and the exit hole of the non-moved clamping plate, forming a two-way position locking of the moved clamping plate and the fixed clamping plate, thereby completing the dynamic switching function of different clamping modes.

[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0023] Please see Figures 1-5This utility model provides an embodiment of a highly flexible iron bed welding robot, including a supporting base plate 1; it also includes a mounting plate 2, a limiting frame 3, a clamping plate 4, a reset hole 5, an outlet hole 6, an L-shaped plate 7, a fixing plate 8, a cylinder 9, a connecting plate 10, and a limiting pin 11. Two mounting plates 2 are symmetrically arranged on the left and right sides of the top of the supporting base plate 1. A limiting frame 3 is symmetrically arranged on the top of the two mounting plates 2. Four clamping plates 4 are stacked inside the limiting frame 3. Two reset holes 5 are opened through the front and rear sides of the top of each of the four clamping plates 4. Two outlet holes 6 are opened through the front and rear sides of the top of each of the four clamping plates 4, corresponding to the positions of the reset holes 5. An L-shaped plate 7 is arranged on the rear side of the limiting frame 3. A fixing plate 8 is connected to the top of the L-shaped plate 7. A cylinder 9 is arranged on the top of the fixing plate 8. The output end of the cylinder 9 passes through the fixing plate 8 and is connected to the connecting plate 10. The front and rear sides of the bottom of the connecting plate 10 are provided with… Two limiting pins 11 are provided. Through the slot 12, the clamping plate 4 matching the shape of the workpiece is pushed to the outside of the limiting frame 3 until the side of the clamping plate 4 with the locking groove 13 is completely moved to the outside of the limiting frame 3. The other three clamping plates 4 are left inside the limiting frame 3. Then, the connecting plate 10 is driven to move downward by the cylinder 9. The connecting plate 10 drives the limiting pins 11 to move downward until the limiting pins 11 are inserted into the reset hole 5 of the clamping plate 4 that has been moved out and the exit hole 6 of the clamping plate 4 that has not been moved out. This fixes the position of the clamping plate 4 that has been moved out and the position that has not been moved out, and realizes the function of free switching. This solves the problem that common iron bed welding robots only have the function of clamping and can clamp the workpiece, but lack the function of free switching. This cannot guarantee the flexibility of the welding robot and is prone to the fixed shape of the clamp, which can only clamp the workpiece with a single shape, thus affecting the flexibility of the welding robot.

[0024] Please see Figures 2-5 In this embodiment, a slot 12 is provided in the middle of one side of the limiting frame 3, and four different shaped slots 13 are provided on the side of the four clamping plates 4 away from the slot 12. The four different shaped slots 13 can be adapted to workpieces with different shapes. Two limiting plates 14 are provided on the side of the clamping plate 4 near the slot 12 at the front and rear ends. Two sliders 15 are provided on the front and rear sides of the bottom of the mounting plate 2. The position of the clamping plate 4 is limited by the two limiting plates 14 to prevent the clamping plate 4 from leaving the limiting frame 3 when moving. Two T-shaped slide rails 16 are provided on the front and rear sides of the top of the supporting base plate 1, corresponding to the position of the sliders 15. The sliders 15 are slidably connected to the T-shaped slide rails 16, and the sliders 15 slide along the trajectory of the T-shaped slide rails 16.

[0025] Please see Figures 1-5In this embodiment, a left side plate 17 is provided on the left side of the top of the support base plate 1, and a right side plate 18 is provided on the right side of the top of the support base plate 1. The left side plate 17 and the right side plate 18 limit the sliding position of the slider 15, thereby preventing the slider 15 from disengaging from the T-shaped slide rail 16. A motor 19 is provided on the right side of the right side plate 18. The output end of the left side of the motor 19 passes through the right side plate 18 and is connected to a bidirectional lead screw 20. The motor 19 drives the bidirectional lead screw 20 to rotate in the forward or reverse direction. The left end of the bidirectional lead screw 20 is rotatably connected to the right side of the left side plate 17. A drive block 21 is provided on the front side of both mounting plates 2. The bidirectional lead screw 20 is threadedly connected to the two drive blocks 21. The bidirectional lead screw 20 synchronously drives the two drive blocks 21 to move closer or further away from each other.

[0026] During operation, the clamping plate 4, which matches the shape of the workpiece, is pushed outward from the limiting frame 3 through the slot 12 until the side of the clamping plate 4 with the locking groove 13 is completely removed from the area of ​​the limiting frame 3, while the other three clamping plates 4 remain in the positioning state inside the limiting frame 3. Then, the connecting plate 10 is moved downward in the vertical direction by the cylinder 9, and the linkage limiting pin 11 moves downward in sync, so that the limiting pin 11 accurately passes through the reset hole 5 of the moved clamping plate 4 and the exit hole 6 of the non-moved clamping plate 4, forming a connection between the moved clamping plate 4 and the workpiece. With the bidirectional position locking of the fixed clamping plate 4, after the clamping plate 4 is adjusted, the workpiece is placed between the two outwardly moved clamping plates 4. Then, the bidirectional lead screw 20 is driven to rotate in the forward direction by the motor 19. The bidirectional lead screw 20 synchronously drives the two drive blocks 21 to move closer to each other. The two drive blocks 21 synchronously drive the two mounting plates 2 to move closer to each other. The two mounting plates 2 synchronously drive the two outwardly moved clamping plates 4 to move closer to each other until the workpiece is clamped by the two outwardly moved clamping plates 4. Then the workpiece can be welded, realizing the function of free switching.

[0027] Through the above steps, the clamping plate 4 matching the shape of the workpiece is pushed outward of the limiting frame 3 by the slot 12 until the side of the clamping plate 4 with the locking groove 13 is completely moved to the outside of the limiting frame 3, while the other three clamping plates 4 remain inside the limiting frame 3. Then, the connecting plate 10 is driven to move downward by the cylinder 9, and the connecting plate 10 drives the limiting pin 11 to move downward until the limiting pin 11 is inserted into the reset hole 5 of the clamping plate 4 that has been moved out and the exit hole 6 of the clamping plate 4 that has not been moved out, thereby fixing the position of the clamping plate 4 that has been moved out and the position that has not been moved out, realizing the function of free switching. This solves the problem that common iron bed welding robots only have the function of clamping and can clamp workpieces, but lack the function of free switching, which cannot guarantee the flexibility of the welding robot. The shape of the clamp is fixed, which can only clamp workpieces with a single shape, affecting the flexibility of the welding robot.
