Description

Technical Field

[0001] This invention relates to the field of welding auxiliary equipment technology, specifically to an intelligent rocker arm for welding loader-coordinated jigs. Background Technology

[0002] The welding rocker arm is the core rotating clamping component of the workpiece welding fixture. It is mainly composed of the rocker arm body, rotating shaft, positioning fixture, and locking mechanism. The rocker arm can achieve multi-angle rotation by relying on the rotating shaft, which can flexibly rotate the welding surface of the workpiece to be welded without repeatedly disassembling and assembling the workpiece. It is suitable for continuous welding of multi-faceted welds. The rocker arm body is made of thickened steel and welded, which is rigid and resistant to welding heat deformation. The matching quick locking component can accurately lock any rotation angle to ensure welding positioning accuracy. It can be used with various profiles and sheet metal special positioning blocks. It is widely used in batch welding processes of vehicle frames, brackets, aluminum profiles, etc., effectively reducing the time spent clamping the workpiece, reducing the labor intensity of manual rotation, and steadily improving the consistency of weld formation and the overall welding processing efficiency.

[0003] In the prior art, such as the welding rocker arm for auxiliary welding with application number 202020757232.2, the technical solution is as follows: it includes a fixed base, a first fixed member and a second fixed member. The fixed base has a movable block in the middle. The movable block is hinged to the first fixed member through a first rotating rod. The first fixed member and the second fixed member are hinged to each other through a second rotating rod. The upper end of the fixed base has a motor and the lower end of the motor has a lead screw. The movable block is installed on the lead screw. The middle of the second fixed member has a sliding groove, and the sliding groove has a slider and a first fine adjustment plate.

[0004] As a core tooling for workpiece positioning and flipping, the welding rocker arm of the jig currently mostly adopts a purely manual rotation control structure. It relies on manual pushing and pulling and bolt tightening to complete the angle adjustment. The adjustment accuracy is poor, and the operation is time-consuming and labor-intensive. The existing rocker arms do not have matching multi-axis linkage drive components, and cannot be linked and matched with the welding robot program. It is difficult to automatically and flexibly switch between multiple angle positions according to different jig shapes. When the robot is welding, the workpiece posture adjustment is limited. Complex welds require multiple stops for manual fine-tuning, which interrupts the welding continuity, lengthens the processing cycle, and results in poor positioning consistency. It cannot meet the continuous high-precision operation requirements of automated intelligent welding production lines.

[0005] In view of this, in-depth research was conducted on the above issues, which led to the creation of this case.

[0006] To address the aforementioned issues, an innovative design was developed based on the existing welding rocker arm. Summary of the Invention

[0007] The purpose of this invention is to provide an intelligent rocker arm for welding loader-cooperative jigs, in order to solve the problems mentioned in the background art, such as difficulty in adapting to jigs of various shapes and low angular rotation accuracy.

[0008] To achieve the above objectives, the present invention provides the following technical solution: A smart rocker arm for welding loader-cooperative fixtures includes a fixed plate. A controller is fixedly installed on the front side of the fixed plate, and a welding robot is arranged on the left side of the fixed plate. A first motor is fixedly installed on the right side of the fixed plate, and the output end of the first motor is connected to a first rocker arm bracket. A second rocker arm bracket is fixedly installed on the lower left side of the first rocker arm bracket. A second motor is fixedly installed at the bottom of the second rocker arm bracket, and the output end of the second motor is connected to a rotating cylinder. A turntable is horizontally rotatably connected inside the rotating cylinder, and the turntable forms a rotating structure. A toothed column is penetrating through the turntable, and the toothed column is located at the center of the turntable, forming a lifting structure. A support frame is fixedly installed on the upper surface of the turntable, and a half gear is rotatably connected above the support frame and meshes with the toothed column. A connecting rod is connected to the outside of the half gear, and a support base plate is fixedly installed at the outer end of the connecting rod. Three sets of clamping assemblies are fixedly installed on the upper surface of the support base plate. Clamping plates are slidably connected to the left and right sides of the upper surface of the clamping assemblies, and a partition is fixedly installed between the clamping assemblies located on the front and rear sides of the support base plate.

[0009] Preferably, the rotating cylinder is rotatably connected above the second rocker arm bracket, and a heat dissipation vent is provided on the rear side of the second rocker arm bracket.

[0010] Using the above technical solution, the welding operation will continuously generate high temperature radiation. The heat dissipation port can quickly dissipate the heat generated by the operation of the third motor and the rotating cylinder, as well as the welding heat radiation, thereby reducing the working temperature of the transmission components, avoiding overheating and speed reduction of the motor, high temperature deformation and jamming of the gear assembly, extending the service life of the third motor and the rotating cylinder, and reducing the frequency of downtime maintenance.

[0011] Preferably, a third motor is fixedly installed on the right side of the rotating cylinder, and the output end of the third motor is connected to a bevel gear, and a bevel gear ring is meshed at the bottom of the bevel gear.

[0012] Using the above technical solution, the bevel gear reversing transmission occupies less internal space in the rotating cylinder, the tooth meshing transmission ratio is constant, there is no slippage, the rotation angle control of the turntable is highly accurate, the third motor independently drives the turntable to rotate, and does not interfere with the rotation of the rotating cylinder controlled by the second motor, realizing independent adjustment of the rotation and pitch axes, which can flexibly switch the circumferential position of the workpiece to meet the welding requirements of ring and multi-ring welds, and the transmission torque is sufficient, so that the rotation of the heavy-duty loader jig is smooth without jamming.

[0013] Preferably, the bevel gear ring is fixedly installed on the upper surface of the turntable, and when the bevel gear ring rotates, the turntable is driven to form a rotating structure through the meshing of the bevel gear ring.

[0014] Using the above technical solution, the bevel gear ring fully covers the outer edge of the turntable, ensuring uniform force distribution. Under heavy-duty fixture clamping conditions, rotation will not result in overload wear on one side of the tooth surface. After stopping the machine, the turntable will not rotate due to the weight of the workpiece, eliminating the need for an additional locking mechanism. Positioning is stable, and the rotation angle can be accurately recorded by the controller, ensuring that the welding posture of fixtures in the same batch is completely consistent, eliminating the angle error caused by manual rotation, and improving the uniformity of weld formation.

[0015] Preferably, a guide post is fixedly installed in the middle of the turntable, and a slide rod runs through the inside of the guide post, with a toothed post slidably connected to the outside of the slide rod.

[0016] Using the above technical solution, the slide rod and guide column form a dual axial limit on the toothed column, and there is no left or right deviation during the lifting process. This ensures that the meshing gap between the toothed column and the half gear is constant and there will be no tooth skipping or tooth dislodging failures. The slide rod constrains the linear movement of the toothed column throughout the entire process, the lifting stroke is controllable, and the pitch adjustment range is precise and stable.

[0017] Preferably, a fourth motor is fixedly installed on the inner side of the bottom of the rotating cylinder, and the output end of the fourth motor is connected to a transmission gear, which is meshed with the bottom of the toothed column.

[0018] Using the above technical solution, the fourth motor independently drives the toothed column lifting and controls the workpiece pitch angle separately. It is driven separately from the three axes of rotation and rocker arm swing, with clear adjustment logic. The controller can independently control the pitch angle in a closed loop. The toothed meshing transmission has a large lifting thrust, which can support the smooth lifting and lowering of heavy loader jigs. The threaded lifting mechanism is prone to jamming, while the gear drive has a faster response, sensitive angle fine adjustment, and can accurately control even small pitch angles, making it suitable for small-angle precision weld welding.

[0019] Preferably, an extension sleeve is fixedly installed on the top of the rotating cylinder, and a slide rod is fixedly installed on the top surface inside the extension sleeve. A slot is opened on the side of the rotating cylinder, and the slot provides space for the moving path of the connecting rod. A universal dust cover is installed on the outside of the slot.

[0020] By adopting the above technical solution, the installation length of the extended sleeve and slide rod is increased, which improves the stability of the toothed column lifting and guiding. The slot provides sufficient space for the connecting rod to swing up and down, avoiding deformation caused by the rod colliding with the cylinder. The universal dust cover bends synchronously with the connecting rod, completely sealing the slot gap and preventing welding sparks, welding slag, and dust from entering the cylinder, thus reducing the workload of cleaning and maintaining the transmission mechanism.

[0021] Preferably, a fifth motor is fixedly installed on the left side of the clamping assembly, and the output end of the fifth motor is connected to a threaded rod, which is rotatably connected to the inner cavity of the clamping assembly housing.

[0022] Using the above technical solution, each clamp is driven by an independent motor, and the clamping width of the three clamping components can be adjusted synchronously or individually to adapt to the segmented positioning of loader jigs of different sizes. The motor CNC drives the clamping, replacing manual tightening of bolts. The clamping force is uniform and controllable, and there will be no workpiece deformation caused by excessive clamping on one side.

[0023] Preferably, the threads on the left and right sides of the threaded rod are in opposite directions, and the clamping plate is threaded to the left and right sides of the outer side of the threaded rod, and sliders are provided on the bottom of the front and rear sides of the clamping plate.

[0024] Using the above technical solution, when the fifth motor drives the threaded rod to rotate, the left and right clamping plates move synchronously in opposite directions. A single drive can complete the centering and clamping without the need to adjust the clamping plates on both sides separately, which greatly improves the clamping efficiency. The slider shares the load of the clamping plates, resulting in low sliding resistance and smooth clamping and translation. There will be no jamming of one side of the clamping plate, ensuring accurate positioning of the jig center. Multiple sets of clamps work together to center, and there is no workpiece clamping deviation.

[0025] Preferably, the upper surface of the clamping assembly is provided with a sliding groove, and the slider is slidably connected inside the sliding groove. Furthermore, the edges of the sliding groove and the left and right sides of the clamping plate are all equipped with accordion dust covers.

[0026] Using the above technical solution, the slide rail limits the slider throughout its entire movement, the clamping plate moves horizontally without warping or deviation, and maintains positioning accuracy even after long-term repeated clamping. The accordion dust cover folds synchronously with the extension and retraction of the clamping plate, completely sealing the slide rail gaps. Welding slag and metal dust cannot enter the slide rail, avoiding slider jamming and wear, extending the service life of the clamping sliding parts, and continuously ensuring the stable operation of the automatic clamping mechanism.

[0027] Compared with the prior art, the beneficial effects of the present invention are: the intelligent rocker arm for loader cooperating with fixture welding, 1. Equipped with multi-axis linkage rotation and pitch composite angle adjustment, this intelligent rocker arm integrates multiple independent drive motors. The first motor controls the overall rocker arm swing, the second motor drives the rotating cylinder to pitch, the third motor drives the turntable to rotate circumferentially, and the fourth motor fine-tunes the pitch angle of the support base plate through toothed columns and half gears, forming a three-axis linkage angle adjustment mechanism. With the built-in angle detection and feedback module of the controller, the rotation data of each axis is collected in real time to form a closed-loop control. For the complex annular and multi-angle welds of loader jigs, the tilt and rotation posture of the workpiece can be switched at will, and even small angles can be precisely fine-tuned. Traditional tooling only has a single manual rotation, which has large angle errors and is cumbersome to adjust. This device adjusts in multiple dimensions simultaneously, and the welding robot can continuously complete multi-face welds without stopping and re-clamping in the middle. The angle control accuracy is greatly improved, perfectly adapting to the needs of complex welding path operations. 2. Equipped with multiple sets of synchronous reverse threaded clamps, fully automatic centering and clamping. Three independent clamping components are arranged on the support base plate. Each set is driven by a fifth motor to reverse threaded rod, which drives the clamping plates on both sides to synchronously center and clamp. With the help of sliding groove and slider limit structure, the clamping and centering accuracy is high. The three sets of clamps work together to position and can stably fix loader jigs of different specifications. The clamping force is CNC controllable, avoiding workpiece displacement and profile damage caused by uneven tightening force during manual tightening. The bellows dust cover isolates welding slag and protects the sliding structure, ensuring long-term stable operation of automatic clamping. The entire clamping process is started with one button by the controller, eliminating the need for manual bolt tightening and clamping plate adjustment, greatly shortening the workpiece loading and unloading time, realizing full automation of the robot welding process, reducing positioning deviation caused by manual operation, and improving the welding consistency of jigs in the same batch.

[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0031] Please see Figure 1-10 The present invention provides a technical solution: A smart rocker arm for loader-coordinated jig welding includes a fixed plate 1, a controller 2 fixedly mounted on the front side of the fixed plate 1, a welding robot mounted on the left side of the fixed plate 1, a first motor 3 fixedly mounted on the right side of the fixed plate 1, and a first rocker arm bracket 4 connected to the output end of the first motor 3. A second rocker arm bracket 5 is fixedly mounted on the lower left side of the first rocker arm bracket 4, a second motor 6 is fixedly mounted on the bottom of the second rocker arm bracket 5, and a rotating cylinder 7 is connected to the output end of the second motor 6. A turntable 8 is horizontally rotatably connected inside the rotating cylinder 7, and the turntable 8 forms a rotating structure. Teeth are formed through the interior of the turntable 8. The toothed column 14 is located at the center of the turntable 8 to form a lifting structure. A support frame 17 is fixedly installed on the upper surface of the turntable 8. A half gear 18 is rotatably connected above the support frame 17 and meshes with the toothed column 14. A connecting rod 19 is connected to the outside of the half gear 18, and a support base plate 21 is fixedly installed on the outer end of the connecting rod 19. Three sets of clamping assemblies 22 are fixedly installed on the upper surface of the support base plate 21. Clamping plates 25 are slidably connected to the left and right sides of the upper surface of the clamping assembly 22. A partition plate 26 is fixedly installed in the middle of the clamping assemblies 22 located on the front and rear sides of the support base plate 21.

[0032] The rotating cylinder 7 is rotatably connected above the second rocker arm bracket 5, and the second rocker arm bracket 5 has a heat dissipation vent 501 on its rear side. The welding operation will continuously generate high temperature radiation. The heat dissipation vent 501 can quickly dissipate the heat generated by the operation of the third motor 9 and the rotating cylinder 7, as well as the welding heat radiation, thereby reducing the working temperature of the transmission components, avoiding overheating and speed reduction of the motor, high temperature deformation and jamming of the gear assembly, extending the service life of the third motor 9 and the rotating cylinder 7, and reducing the frequency of downtime maintenance.

[0033] A third motor 9 is fixedly installed on the right side of the rotating cylinder 7, and the output end of the third motor 9 is connected to a bevel gear 10. A bevel gear ring 11 is meshed with the bottom of the bevel gear 10. The bevel gear ring 11 is fixedly installed on the upper surface of the turntable 8. When the bevel gear ring 11 rotates, it drives the turntable 8 to rotate through the meshing of the bevel gear ring 11. A guide post 12 is fixedly installed in the middle of the turntable 8, and a slide rod 13 passes through the guide post 12. A toothed post 14 is slidably connected to the outside of the slide rod 13. The bevel gear 10 reversing transmission occupies less internal space in the rotating cylinder 7, the toothed meshing transmission ratio is constant, there is no slippage, and the rotation angle control of the turntable 8 is highly accurate. The third motor 9 independently drives the rotation of the turntable 8, and does not interfere with the rotation of the rotating cylinder 7 controlled by the second motor 6. It realizes independent adjustment of the rotation and pitch axes, and can flexibly switch the circumferential position of the workpiece. It meets the welding requirements of ring and multi-ring welds, with sufficient transmission torque. The heavy-duty loader jig rotates without jamming. The bevel gear ring 11 fully covers the outer edge of the turntable 8, ensuring uniform force distribution. Under heavy-duty jig clamping conditions, rotation will not cause overload wear on one side of the tooth surface. After stopping, the turntable 8 will not rotate due to the weight of the workpiece, eliminating the need for an additional locking mechanism. The positioning is stable, and the rotation angle can be accurately recorded by the controller 2, ensuring that the welding posture of jigs in the same batch is completely consistent, eliminating the angle error caused by manual rotation, and improving the uniformity of weld formation. The slide rod 13 and the guide column 12 form a double axial limit on the toothed column 14, with no left or right deviation during the lifting process. It ensures that the meshing gap between the toothed column 14 and the half gear 18 is constant, preventing tooth skipping or tooth loss. The slide rod 13 constrains the linear movement of the toothed column 14 throughout the entire process, making the lifting stroke controllable and the pitch adjustment range precise and stable.

[0034] A fourth motor 15 is fixedly installed on the inner bottom of the rotating cylinder 7, and a transmission gear 16 is connected to the output end of the fourth motor 15. The transmission gear 16 is meshed with the bottom of the toothed column 14. An extension sleeve 701 is fixedly installed on the top of the rotating cylinder 7, and a slide rod 13 is fixedly installed on the inner top surface of the extension sleeve 701. A slot 702 is opened on the side of the rotating cylinder 7, and the slot 702 provides space for the movement path of the connecting rod 19. A universal dust cover 20 is installed on the outside of the slot 702. The fourth motor 15 independently drives the toothed column 14 to lift and lower, and independently controls the workpiece pitch angle. It is driven separately from the rotation and rocker arm swing axes, and the adjustment logic is clear. The controller 2 can independently control the pitch angle. The closed-loop control of the elevation angle and the high thrust of the toothed meshing transmission enable the smooth lifting and lowering of the loaders' jigs, which can withstand the impact of threaded lifting mechanisms. The gear drive offers a faster response and more sensitive angle fine-tuning, allowing for precise control of even small pitch angles. It is also suitable for welding small-angle precision welds. The extension sleeve 701 extends the installation length of the slide rod 13, improving the stability of the toothed column 14 in lifting and guiding. The slot 702 provides ample space for the pitch swing of the connecting rod 19, preventing the rod from colliding with the cylinder and causing deformation. The universal dust cover 20 bends synchronously with the connecting rod 19, completely sealing the gap of the slot 702 to prevent welding sparks, slag, and dust from entering the cylinder, thus reducing the workload of cleaning and maintaining the transmission mechanism.

[0035] A fifth motor 23 is fixedly installed on the left side of the clamp assembly 22, and the output end of the fifth motor 23 is connected to a threaded rod 24. The threaded rod 24 is rotatably connected to the inner cavity of the clamp assembly 22 housing. The threads on the left and right sides of the threaded rod 24 have opposite directions. The clamping plate 25 is threaded to the left and right sides of the threaded rod 24. Slider blocks 2501 are provided on the bottom of the front and rear sides of the clamping plate 25. The upper surface of the clamp assembly 22 is provided with a sliding groove 2201, and the slider 2501 is slidably connected to the inside of the sliding groove 2201. The edge of the sliding groove 2201 and the left and right sides of the clamping plate 25 are equipped with accordion dust covers 27. Each clamp is driven by an independent motor. The clamping width of the three clamp assemblies 22 can be adjusted synchronously or individually to adapt to the segmented positioning of different sized loader fixtures. The motor CNC drives the clamping, replacing manual tightening of bolts. The clamping force is uniform and controllable, and there will be no... Excessive clamping on one side can cause workpiece deformation. When the fifth motor 23 drives the threaded rod 24 to rotate, the left and right clamping plates 25 move synchronously in opposite directions. A single drive can complete the centering and clamping without the need to adjust the clamping plates separately, greatly improving clamping efficiency. The slider 2501 shares the load of the clamping plates, resulting in low sliding resistance and smooth clamping and translation. It will not cause one-sided clamping plate jamming, ensuring accurate center positioning of the fixture. Multiple sets of fixtures work together to center, and there is no workpiece clamping deviation. The slide groove 2201 limits the slider 2501 throughout its entire range, and the clamping plate 25 moves without warping or deviation. It maintains positioning accuracy even after long-term repeated clamping. The bellows dust cover 27 folds synchronously with the extension and retraction of the clamping plates, completely sealing the gap of the slide groove 2201. Welding slag and metal dust cannot enter the interior of the slide groove 2201, avoiding the slider 2501 from jamming and wear, extending the service life of the sliding parts of the fixture, and continuously ensuring the stable operation of the automatic clamping mechanism.

[0036] Working principle: When in use, the intelligent rocker arm for welding with a collaborative fixture relies on the controller 2 to achieve closed-loop linkage of multiple motors, integrates a multi-dimensional angle adjustment mechanism and a fully automatic centering and clamping mechanism, and works in conjunction with a welding robot to achieve fully automated high-precision welding, solving the defects of traditional tooling such as manual angle adjustment, manual clamping, poor accuracy and low efficiency. Before operation, the loader fixture is placed on the support base plate 21. The controller 2 issues a clamping command, and the fifth motor 23 of each group drives the reverse threaded rod 24 to rotate. The clamping plates 25 on both sides move synchronously towards each other along the slide groove 2201 to complete automatic centering and clamping. The slider 2501 and the bellows dust cover 27 ensure smooth sliding and prevent dust and slag. The partition 26 separates the positioning area to prevent the fixture from sliding laterally. After the welding robot starts, controller 2 performs multi-axis angle adjustment according to the preset welding path: the first motor 3 drives the first rocker arm support 4 and the second rocker arm support 5 to swing as a whole, coarsely adjusting the workpiece's distance from the workpiece; the second motor 6 drives the rotating cylinder 7 to achieve a wide range of pitch; the third motor 9 drives the turntable 8 to rotate circumferentially through bevel gear 10 and bevel ring 11; the fourth motor 15 drives the toothed column 14 to rise and fall, and the meshing half gear 18 drives the connecting rod 19 to finely adjust the pitch of the support base plate 21. Each axis is equipped with an angle detection feedback module, which transmits position signals in real time to form a closed-loop control, accurately matching any posture required for complex welding paths, and achieving multi-dimensional high-precision angle adjustment; The welding robot is programmed in conjunction with an intelligent rocker arm, eliminating the need for manual adjustments to the workpiece angle throughout the entire process. Automated multi-axis adjustment replaces manual pushing, pulling, and bolt tightening, significantly reducing auxiliary time and improving welding efficiency. Closed-loop precision angle control ensures consistent weld formation parameters for each weld, eliminating quality fluctuations caused by human intervention. The entire system intelligently plans the welding posture through a control system, achieving fully automated jig loading, positioning, multi-angle rotation, and continuous welding, reducing worker labor intensity and consistently improving the quality of welded products.
