Description

Technical Field

[0001] The present invention relates to the technical field of positioning jigs, and specifically to a welding positioning jig for metal hinge joints. Background Art

[0002] In modern manufacturing, metal hinge joints, as key components for connecting various parts and achieving rotational functions, are widely used in many fields such as furniture, doors and windows, automobiles, machinery, etc. The quality and performance of metal hinge joints directly affect the user experience, safety, and reliability of related products.

[0003] The patent with the publication number CN222429779U relates to a new type of hinge joint welding positioning jig, which includes a copper rod, a brass plate installed on the copper rod, and a copper plate arranged on the brass plate. The execution commands include a lifting cylinder and a cylindrical rod fixed on the lifting cylinder and its cylinder top plate, which are vertically arranged. During use, the to-be-welded plate and the hinge joint positioning holes are combined and placed on the plane of the copper plate. The lifting cylinder is controlled to execute actions through the air circuit of the throttle valve, and the concentricity of the spatial positions of the hinge joint and the plate is restricted and fixed by lifting from the bottom surface of the copper plate. This device can perform plate welding through a welding robot or other manual welding machines. After welding is completed, the lifting cylinder returns to the zero position. After loosening the cylindrical rod, the material taking action is completed manually. Moreover, the lifting cylinder can be extended, retracted, or lifted according to the actual situation, and there is no need to replace the welding jig due to product replacement, achieving the technical effect of welding plate parts for various situations and realizing efficient and rapid plate welding operations. However, before fixing the hinge joint, this device is prone to incorrect positions of the fixed hinge joint due to mechanical vibration or incorrect placement of the hinge joint by workers, which may easily lead to welding errors. Therefore, a welding positioning jig for metal hinge joints is proposed to solve the above problems. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a welding positioning jig for metal hinge joints in view of the deficiencies in the above-mentioned prior art.

[0005] To solve the above technical problems, the technical solution adopted by the present invention is: a metal hinge welding positioning tooling, including a workbench, on the top of the workbench is provided a welding arm, the top of the workbench is fixedly connected with a welding table, on the top of the welding table is fixedly connected with a U-shaped plate I, the top of the workbench is fixedly connected with a motor, the output end of the motor is fixedly connected with a lead screw, the circumferential surface of the lead screw is movably connected with a sliding plate, the surface of the sliding plate is fixedly connected with an inclined plate I, the front part of the U-shaped plate I is fixedly connected with a sliding rod, the circumferential surface of the sliding rod is slidably connected with a lifting plate, the inner wall of the U-shaped plate I is fixedly connected with an L-shaped plate, the inner wall of the L-shaped plate is fixedly connected with a pressing plate, the left side of the L-shaped plate is fixedly connected with an inclined strip plate, the inner wall of the lifting plate is fixedly connected with a fixed rod through a spring, the circumferential surface of the fixed rod is slidably connected with a push plate I, the front part of the push plate I is fixedly connected with a U-shaped plate II, the top of the U-shaped plate II is fixedly connected with an inclined plate II, the bottom of the lifting plate is fixedly connected with a triangular plate, on the top of the U-shaped plate I is provided a slag removal device for cleaning welding slag, the inner wall of the workbench is provided with an anti-jamming device for avoiding jamming during use, the inner wall of the welding table is rotationally connected with the circumferential surface of the lead screw, the top of the workbench is in contact with the bottom of the inclined plate I, the surface of the lifting plate is in contact with the inner wall of the welding table, the top of the lifting plate is in contact with the bottom of the U-shaped plate II, the bottom of the triangular plate is in contact with the top of the workbench. When starting to weld the hinge, place the hinge in the welding area. After placement, the hinge contacts the pressing plate, so as to fix the hinge, making the hinge not shake or shift during welding, thereby improving the quality and aesthetics of the weld seam. At the same time, the backward movement of the U-shaped plate II drives the backward movement of the push plate I and drives the spring to stretch, so that the hinge can be adjusted before being fixed, and the hinge placed on the lifting plate is pushed towards the middle, thus avoiding the deviation of the placement position of the hinge, and improving the welding accuracy of the hinge.

[0006] Preferably, the slag removal device includes a fixed block fixedly connected to the top of the lifting plate. A first rotating rod is rotatably connected to the inner wall of the fixed block through a torsion spring. A straight plate is fixedly connected to the circumferential surface of the first rotating rod. A second rotating rod is fixedly connected to the side of the straight plate away from the fixed block. A slag pushing plate is fixedly connected to the circumferential surface of the second rotating rod. A U-shaped frame is fixedly connected to the top of the sliding plate. An elastic telescopic plate is fixedly connected to the inner wall of the U-shaped frame. A roller is rotatably connected to the telescopic end of the elastic telescopic plate. A conduction plate is fixedly connected to the bottom of the welding table. A convex block is fixedly connected to the bottom of the conduction plate. The top of the welding table is in contact with the bottom of the slag pushing plate. The circumferential surface of the roller is in contact with the bottom of the conduction plate. During the welding process, the second rotating rod rotates to drive the slag pushing plate to move, so that the welding slag generated during the welding process can be cleaned to avoid excessive accumulation of welding slag, which requires manual cleaning by workers, resulting in more cumbersome work. At the same time, when the roller passes over the convex block, the elastic telescopic plate will reset and retract, driving the roller to move upward, so that vibration can be generated on the conduction plate. When the vibration is transmitted to the welding table, the welding slag attached to it can be loosened and dropped, thereby reducing the labor intensity of workers and improving the work efficiency of workers.

[0007] Preferably, the anti-jamming device includes a collection box slidably connected to the inner wall of the workbench. A rotating plate is rotatably connected to the inner wall of the collection box through a torsion spring. An H-shaped frame is fixedly connected to the rear of the U-shaped frame.

A connecting block is fixedly connected to the front of the connecting plate. A slag removing ring is fixedly connected to the front of the connecting block. The surface of the collection box is in contact with the inner wall of the second pushing plate. The front of the rotating plate is in contact with the rear of the second pushing plate. The circumferential surface of the lead screw is in contact with the inner wall of the slag removing ring. During the process of cleaning the welding slag, the connecting plate moves to drive the second pushing plate to move, so that the welding slag falling into the collection box can be pushed and scattered, avoiding the waste of the internal space of the collection box due to the accumulation of welding slag in the same place. If the welding slag accumulates too high in the same place, it will cause the welding slag to contact the operating components of the device, which is very likely to cause problems such as device jamming, thus affecting normal welding. At the same time, the connecting block moves to drive the slag removing ring to move, so that the welding slag falling on the surface of the lead screw can be scraped off, avoiding excessive accumulation of welding slag on the surface of the lead screw, which affects the normal operation of the device, and further causing the welding to be unable to proceed normally, resulting in unnecessary losses caused by the waste of time and resources.

[0008] The present invention adopts the above technical solutions and can bring the following beneficial effects:

[0009] 1. The welding positioning tooling for the metal hinge leaf, through the cooperation of the workbench, welding arm, welding table, U-shaped plate 1, motor, lead screw, sliding plate, inclined plate 1, sliding rod, lifting plate, L-shaped plate, pressing plate, inclined strip plate, fixed rod, pushing plate 1, U-shaped plate 2, inclined plate 2, and triangular plate, when starting the welding of the hinge leaf, place the hinge leaf in the welding area. After placement, the hinge leaf contacts the pressing plate, so as to fix the hinge leaf, making the hinge leaf not shake or shift during welding, thereby improving the quality and aesthetics of the weld seam. At the same time, when U-shaped plate 2 moves backward, it drives pushing plate 1 to move backward and drives the spring to stretch, so that the hinge leaf can be adjusted before being fixed, and the hinge leaf placed on the lifting plate is pushed towards the middle, thus avoiding the deviation of the placement position of the hinge leaf and improving the welding accuracy of the hinge leaf.

[0010] 2. The welding positioning tooling for the metal hinge leaf, through the cooperation of the fixed block, rotating rod 1, straight plate, rotating rod 2, slag pushing plate, U-shaped frame, elastic telescopic plate, roller, conduction plate, and convex block, during the welding process, the rotation of rotating rod 2 drives the slag pushing plate to move, so that the welding slag generated during the welding process can be cleaned to avoid excessive accumulation of welding slag, which requires manual cleaning by workers and makes the work more cumbersome. At the same time, when the roller crosses the convex block, the elastic telescopic plate will reset and retract, driving the roller to move upward, so that vibration can be generated on the conduction plate. When the vibration is transmitted to the welding table, the welding slag attached to it can be loosened and fall off, thereby reducing the labor intensity of workers and improving the work efficiency of workers.

[0011] 3. The welding positioning tooling for the metal hinge leaf, through the cooperation of the collection box, rotating plate, H-shaped frame, connecting plate, pushing plate 2, connecting block, and slag removing ring, during the process of cleaning the welding slag, the movement of the connecting plate drives the pushing plate 2 to move, so that the welding slag falling into the interior of the collection box can be pushed and dispersed, avoiding the accumulation of welding slag in the same place in the collection box, resulting in waste of the internal space of the collection box. If the welding slag accumulates too high in the same place, it will cause the welding slag to contact the operating components of the device, which is extremely likely to cause problems such as device jamming, thereby affecting normal welding. At the same time, the movement of the connecting block drives the slag removing ring to move, so that the welding slag falling on the surface of the lead screw can be scraped off, avoiding excessive accumulation of welding slag on the surface of the lead screw and affecting the normal operation of the device, and further causing the welding to be unable to proceed normally, resulting in waste of time and resources and unnecessary losses.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0022] Please refer to Figures 1 - 8, an embodiment of the present invention is: a welding positioning tooling for a metal hinge, including a workbench 1. A welding arm 2 is arranged on the top of the workbench 1. A welding table 3 is fixedly connected to the top of the workbench 1. A U-shaped plate one 4 is fixedly connected to the top of the welding table 3. A motor 5 is fixedly connected to the top of the workbench 1. The output end of the motor 5 is fixedly connected to a lead screw 6. A sliding plate 7 is movably connected to the circumferential surface of the lead screw 6. An inclined plate one 8 is fixedly connected to the surface of the sliding plate 7. A sliding rod 9 is fixedly connected to the front part of the U-shaped plate one 4. A lifting plate 10 is slidably connected to the circumferential surface of the sliding rod 9. When starting to weld the hinge, place the hinge in the welding area. After placing it, start the motor 5. The motor 5 drives the lead screw 6 to rotate. The rotation of the lead screw 6 will contact the thread on the surface of the lead screw 6 through the slider arranged inside the sliding plate 7, so that the sliding plate 7 can move left and right. The movement of the sliding plate 7 drives the inclined plate one 8 to move. During the movement of the inclined plate one 8, it will contact the inclined surface on the surface of the triangular plate 20, so as to generate an upward extrusion force on the triangular plate 20, and then make the triangular plate 20 move upward. The upward movement of the triangular plate 20 drives the lifting plate 10 to move, and then can drive the hinge on the lifting plate 10 to move together, so that the hinge contacts the pressing plate 12, thereby being able to fix the hinge, so that the hinge will not shake or shift during welding, thereby improving the quality and aesthetics of the weld seam. An L-shaped plate 11 is fixedly connected to the inner wall of the U-shaped plate one 4. A pressing plate 12 is fixedly connected to the inner wall of the L-shaped plate 11. An inclined strip plate 13 is fixedly connected to the left side of the L-shaped plate 11. A fixing rod 14 is fixedly connected to the inner wall of the lifting plate 10 through a spring. A push plate one 15 is slidably connected to the circumferential surface of the fixing rod 14. A U-shaped plate two 16 is fixedly connected to the front part of the push plate one 15. An inclined plate two 17 is fixedly connected to the top of the U-shaped plate two 16. A triangular plate 20 is fixedly connected to the bottom of the lifting plate 10. A slag removal device 18 for cleaning welding slag is arranged on the top of the U-shaped plate one 4. An anti-jamming device 19 for avoiding jamming during use is arranged inside the workbench 1. The inner wall of the welding table 3 is rotatably connected to the circumferential surface of the lead screw 6. The top of the workbench 1 contacts the bottom of the inclined plate one 8. The surface of the lifting plate 10 contacts the inner wall of the welding table 3. The top of the lifting plate 10 contacts the bottom of the U-shaped plate two 16. The bottom of the triangular plate 20 contacts the top of the workbench 1. At the same time, the upward movement of the lifting plate 10 drives the fixing rod 14 to move upward. The movement of the fixing rod 14 drives the push plate one 15 to move upward. The movement of the push plate one 15 drives the U-shaped plate two 16 to move upward. The movement of the U-shaped plate two 16 drives the inclined plate two 17 to move upward. During the upward movement of the inclined plate two 17, the inclined plate two 17 will contact the inclined strip plate 13, so that the inclined strip plate 13 generates a backward extrusion force on the inclined plate two 17 through the inclined surface, forcing the inclined plate two 17 to move backward. The backward movement of the inclined plate two 17 drives the U-shaped plate two 16 to move backward. The backward movement of the U-shaped plate two 16 drives the push plate one 15 to move backward and drives the spring to stretch.Thus, the hinge can be adjusted before being fixed, and the hinge placed on the lifting plate 10 can be pushed towards the middle, thereby avoiding the deviation of the placement position of the hinge and improving the welding accuracy of the hinge.

[0023] The slag removal device 18 includes a fixed block 181 which is fixedly connected to the top of the lifting plate 10. A rotating rod 182 is rotatably connected to the inner wall of the fixed block 181 through a torsion spring. A straight plate 183 is fixedly connected to the circumferential surface of the rotating rod 182. A rotating rod 184 is fixedly connected to the side of the straight plate 183 away from the fixed block 181. A slag pushing plate 185 is fixedly connected to the circumferential surface of the rotating rod 184. During the welding process, the upward movement of the lifting plate 10 drives the fixed block 181 to move upward. The upward movement of the fixed block 181 drives the rotating rod 182 to move upward. The upward movement of the rotating rod 182 drives the straight plate 183 to move upward. During the upward movement of the straight plate 183, it rotates counterclockwise through the torsion spring. The rotation of the straight plate 183 drives the rotating rod 184 to rotate. The rotation of the rotating rod 184 drives the slag pushing plate 185 to move, so that the welding slag generated during the welding process can be cleaned to avoid excessive accumulation of welding slag, which requires manual cleaning by workers and makes the work more cumbersome. A U-shaped frame 186 is fixedly connected to the top of the sliding plate 7. An elastic telescopic plate 187 is fixedly connected to the inner wall of the U-shaped frame 186. A roller 188 is rotatably connected to the telescopic end of the elastic telescopic plate 187. A conduction plate 189 is fixedly connected to the bottom of the welding table 3. A convex block 1810 is fixedly connected to the bottom of the conduction plate 189. The top of the welding table 3 is in contact with the bottom of the slag pushing plate 185. The circumferential surface of the roller 188 is in contact with the bottom of the conduction plate 189. At the same time, the movement of the sliding plate 7 drives the U-shaped frame 186 to move. The movement of the U-shaped frame 186 drives the elastic telescopic plate 187 to move. The movement of the elastic telescopic plate 187 drives the roller 188 to move. The movement of the roller 188 will contact the conduction plate 189 and generate friction force to make the roller 188 rotate. During the movement of the roller 188, it will contact the convex block 1810 and generate an extrusion force on the roller 188 to make the roller 188 move downward. The downward movement of the roller 188 will stretch the elastic telescopic plate 187. When the roller 188 passes over the convex block 1810, the elastic telescopic plate 187 will reset and retract, driving the roller 188 to move upward, so as to vibrate the conduction plate 189. When the vibration is transmitted to the welding table 3, the welding slag attached to it can be loosened and dropped, thereby reducing the labor intensity of workers and improving the work efficiency of workers.

[0024] Working principle: When starting the welding of the hinge, place the hinge in the welding area. After placement, the motor 5 is started. The start of the motor 5 drives the lead screw 6 to rotate. The rotation of the lead screw 6 will contact the thread on the surface of the lead screw 6 through the slider arranged inside the sliding plate 7, so that the sliding plate 7 can move left and right. The movement of the sliding plate 7 drives the first inclined plate 8 to move. During the movement of the first inclined plate 8, it will contact the inclined surface on the surface of the triangular plate 20, so that an upward extrusion force can be generated on the triangular plate 20, and then the triangular plate 20 moves upward. The upward movement of the triangular plate 20 drives the lifting plate 10 to move, and then the hinge on the lifting plate 10 can be driven to move together, so that the hinge contacts the pressing plate 12, thereby fixing the hinge, so that the hinge will not shake or shift during welding, thus improving the quality and aesthetics of the weld. At the same time, the upward movement of the lifting plate 10 drives the fixed rod 14 to move upward. The movement of the fixed rod 14 drives the first push plate 15 to move upward. The movement of the first push plate 15 drives the second U-shaped plate 16 to move upward. The movement of the second U-shaped plate 16 drives the second inclined plate 17 to move upward. During the upward movement of the second inclined plate 17, the second inclined plate 17 will contact the inclined strip plate 13, so that the inclined strip plate 13 generates a backward extrusion force on the second inclined plate 17 through the inclined surface, forcing the second inclined plate 17 to move backward. The backward movement of the second inclined plate 17 drives the second U-shaped plate 16 to move backward. The backward movement of the second U-shaped plate 16 drives the first push plate 15 to move backward and drives the spring to stretch. Thus, the hinge can be adjusted before fixing the hinge, and the hinge placed on the lifting plate 10 can be pushed towards the middle, thereby avoiding the deviation of the placement position of the hinge, so that the welding accuracy of the hinge can be improved.

[0025] During the welding process, the lifting plate 10 moves upward to drive the fixed block 181 to move upward. The upward movement of the fixed block 181 drives the first rotating rod 182 to move upward. The upward movement of the first rotating rod 182 drives the straight plate 183 to move upward. During the upward movement of the straight plate 183, it rotates counterclockwise through the torsion spring. The rotation of the straight plate 183 drives the second rotating rod 184 to rotate. The rotation of the second rotating rod 184 drives the slag pushing plate 185 to move, so that the welding slag generated during the welding process can be cleaned to avoid excessive accumulation of welding slag, which requires manual cleaning by workers, resulting in more cumbersome work. At the same time, the sliding plate 7 moves to drive the U-shaped frame 186 to move. The movement of the U-shaped frame 186 drives the elastic telescopic plate 187 to move. The movement of the elastic telescopic plate 187 drives the roller 188 to move. The movement of the roller 188 will come into contact with the conduction plate 189 and generate frictional force to make the roller 188 rotate. During the movement of the roller 188, it will come into contact with the convex block 1810 and generate an extrusion force on the roller 188 to make the roller 188 move downward. The downward movement of the roller 188 will stretch the elastic telescopic plate 187. When the roller 188 passes over the convex block 1810, the elastic telescopic plate 187 will reset and retract, driving the roller 188 to move upward, so as to vibrate the conduction plate 189. When the vibration is transmitted to the welding table 3, the welding slag attached to it can be loosened and dropped, thereby reducing the labor intensity of workers and improving the work efficiency of workers.

[0026] Please refer to Figures 1 - 8, on the basis of the above embodiments, in another embodiment of the present invention, the anti-jamming device 19 includes a collection box 191. The collection box 191 is slidably connected to the inner wall of the workbench 1. A rotating plate 192 is rotatably connected to the inner wall of the collection box 191 through a torsion spring. A H-shaped frame 193 is fixedly connected to the rear part of the U-shaped frame 186. A connecting plate 194 is fixedly connected to the bottom of the H-shaped frame 193. A second push plate 195 is fixedly connected to the inner wall of the connecting plate 194. During the process of cleaning the welding slag, the movement of the U-shaped frame 186 drives the movement of the H-shaped frame 193. The movement of the H-shaped frame 193 drives the movement of the connecting plate 194. The movement of the connecting plate 194 drives the movement of the second push plate 195, so that the welding slag falling into the interior of the collection box 191 can be pushed and dispersed, avoiding the accumulation of welding slag in the same place in the collection box 191, resulting in waste of the space inside the collection box 191. If the welding slag accumulates too high in the same place, it will cause the welding slag to contact the operating components of the device, which is extremely likely to cause problems such as device jamming, thereby affecting normal welding. When pouring out the welding slag in the collection box 191, the movement of the collection box 191 drives the movement of the rotating plate 192. The movement of the rotating plate 192 will contact the rear part of the second push plate 195, and then generate a squeezing force on the second push plate 195 to make the rotating plate 192 rotate. Only at this time can the collection box 191 be normally pulled out. A connecting block 196 is fixedly connected to the front part of the connecting plate 194. A slag-removing ring 197 is fixedly connected to the front part of the connecting block 196. The surface of the collection box 191 is in contact with the inner wall of the second push plate 195. The front part of the rotating plate 192 is in contact with the rear part of the second push plate 195. The circumferential surface of the lead screw 6 is in contact with the inner wall of the slag-removing ring 197. At the same time, the movement of the connecting plate 194 drives the movement of the connecting block 196. The movement of the connecting block 196 drives the movement of the slag-removing ring 197, so that the welding slag falling on the surface of the lead screw 6 can be scraped off, avoiding excessive accumulation of welding slag on the surface of the lead screw 6 from affecting the normal operation of the device, and further causing the welding to be unable to proceed normally, resulting in waste of time and resources and unnecessary losses.

[0027] Working principle: During the process of cleaning the welding slag, the movement of the U-shaped frame 186 drives the movement of the H-shaped frame 193, the movement of the H-shaped frame 193 drives the movement of the connecting plate 194, and the movement of the connecting plate 194 drives the movement of the second push plate 195. As a result, the welding slag that has fallen inside the collection box 191 can be pushed and scattered, preventing the welding slag from accumulating in the same place inside the collection box 191, which would otherwise waste the space inside the collection box 191. If the welding slag accumulates too high in the same place, it will cause the welding slag to come into contact with the operating components of the device, which is very likely to cause problems such as device jamming, thereby affecting normal welding. When pouring out the welding slag in the collection box 191, the movement of the collection box 191 drives the movement of the rotating plate 192. The movement of the rotating plate 192 will contact the rear part of the second push plate 195, and then exert a squeezing force on the second push plate 195 to make the rotating plate 192 rotate. Only then can the collection box 191 be normally pulled out. At the same time, the movement of the connecting plate 194 drives the movement of the connecting block 196, and the movement of the connecting block 196 drives the movement of the slag-removing ring 197, so as to scrape off the welding slag that has fallen on the surface of the lead screw 6, preventing excessive accumulation of welding slag on the surface of the lead screw 6 from affecting the normal operation of the device, and further causing the welding to be unable to proceed normally, resulting in unnecessary losses caused by waste of time and resources.
