Description

Technical Field

[0001] The invention relates to the technical field of welding fixtures, in particular to a welding fixture for processing hardware products. Background Art

[0002] Hardware refers to parts made of gold, silver, copper, iron, tin and other metals through processing and casting. They mainly play the role of fixing, supporting, processing and decoration. Hardware is widely used in various fields of our lives. However, in the production process of hardware steel support parts, accessories for fixing and assembly will be welded on both ends of the processed steel support, which requires the use of welding equipment, and then the welding fixture is needed to clamp the workpiece and cooperate with the welding equipment for welding.

[0003] The prior art discloses an automatic steel pipe welding device and method with publication number CN114918593A. The device drives the flexible fitting component to rotate around the steel pipe through an extension plate. At this time, a rubber damping wheel cooperates with a folding transmission component to drive the wire feeding component to continuously drive the electrode to feed. The feeding amount of the electrode corresponds to the linear stroke of the rubber damping wheel, thereby realizing automatic mechanical self-welding with high precision and without manual welding.

[0004] However, there are still some defects in the actual use process. Since the welding of the steel support is a simple and regular weld and needs to be mass-produced, the welding fixture still requires workers to release the clamp and then take out the workpiece after welding is completed.

DETAILED DESCRIPTION

[0027] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0028] like Figure 1-Figure 7 A welding fixture for processing hardware products shown in the figure comprises a welding table 1, and welding mechanical arms 2 arranged on both sides of the top of the welding table 1, both sides of the top of the welding table 1 are fixedly connected with L-shaped plates 3, a placing plate 4 is arranged on the side close to the L-shaped plate 3, the eccentric parts of both sides of the placing plate 4 are rotatably connected to the side walls of the L-shaped plate 3, the rotating parts of the placing plate 4 are fixedly connected with gears 5 through the L-shaped plate 3, both sides of the bottom of the welding table 1 are fixedly connected with a bottom plate 6, a through groove 7 is penetrated and opened on the top of the welding table 1 and below the gear 5, a clamping seat 8 is slidably connected with the top of the L-shaped plate 3, a rotating mechanism for rotating pipe welding is arranged on the top of the clamping seat 8, a plurality of placing seats 16 for placing pipes are fixedly connected to the top of the clamping seat 8, and a feeding mechanism for automatically releasing the clamping of the pipe and turning it over is arranged on the bottom plate 6;

[0029] The unloading mechanism includes an electric telescopic cylinder 9, a pair of which are provided, and the electric telescopic cylinders 9 are fixedly connected to the top of the bottom plate 6, a sliding rod 10 is slidably connected to the inner side of the L-shaped plate 3 and located next to the gear 5 and is arranged through the top of the L-shaped plate 3, the output end of the electric telescopic cylinder 9 is fixedly connected to the bottom of the sliding rod 10, a plurality of movable tooth blocks 11 meshing with the gear 5 are fixedly connected to the side wall of the sliding rod 10, a right-angle block 12 with an inclined surface is fixedly connected to the rear side of the side wall of the clamping seat 8, an inwardly recessed groove 41 is provided at the top of the sliding rod 10, a roller 13 for squeezing the right-angle block 12 is fixedly connected to the inner side of the groove 41, a side plate 14 is fixedly connected to the top of the L-shaped plate 3, a pair of return springs 15 are fixedly connected between the side plate 14 and the side wall of the clamping seat 8, and a limiting mechanism for limiting the rotation of the gear 5 is provided next to the sliding rod 10;

[0030] In the process of welding the hardware pipe fittings, the pipe fittings to be welded are placed in the placement seat 16, and then the electric telescopic cylinder 9 can be controlled to start and drive the sliding rod 10 to move upward. At this time, the sliding rod 10 is in the initial position, and the moving tooth block 11 is above the gear 5, so it will not drive the gear 5 to rotate, thereby driving the roller 13 to move upward to squeeze the inclined surface of the right-angle block 12, and then push the right-angle block 12 to move to the closer side, and gradually stretch the reset spring 15, thereby driving the clamping seat 8 to slide on the L-shaped plate 3, and at the same time driving the conical block 18 to insert into the inner hole at the end of the pipe fitting to achieve the effect of clamping the pipe fitting;

[0031] After the welding is completed, the electric telescopic cylinder 9 can be controlled to stop running, and the rotating mechanism and the welding robot arm 2 can be controlled to start the rotation welding of the pipe fitting. After the welding is completed, the electric telescopic cylinder 9 can be controlled to drive the sliding rod 10 to move downward, thereby driving the roller 13 to slide downward, releasing the squeezing of the right-angle block 12, thereby pulling the clamping seat 8 to slide under the elastic force of the reset spring 15, driving the conical block 18 to slide out of the inner hole of the pipe fitting, releasing the clamping of the pipe fitting, and then the sliding rod 10 continues to move downward, driving the moving tooth block 11 to move to the side of the gear 5. At this time, the limiting mechanism will be driven to move out of the side of the gear 5, releasing the rotation restriction of the gear 5, and then through the mutual meshing of the moving tooth block 11 and the gear 5, the gear 5 will be driven to rotate, thereby driving the placement plate 4 to rotate 90 degrees around the eccentric point, and the pipe fittings welded in the placement seat 16 will be discharged, thereby realizing automatic unloading of the device, and finally the electric telescopic cylinder 9 can be controlled to reset upward to the initial position.

[0032] In order to fully weld the pipe fittings, the rotating mechanism includes a rotating motor 17, which is fixedly connected to the top of the clamping seat 8. The adjacent side of the clamping seat 8 is rotatably connected to a conical block 18 for inserting the inner side of the pipe fitting. The output end of the rotating motor 17 passes through the side wall of the clamping seat 8 and is fixedly connected to the side wall of the conical block 18.

[0033] When the unloading mechanism drives the conical block 18 to clamp the two sides of the pipe fitting, the rotary motor 17 can be controlled to start driving the conical block 18 to rotate, and the comprehensive welding of the pipe fitting can be achieved through the cooperation with the welding robot arm 2.

[0034] In order to further improve the automation of the device, a travel switch 19 is fixedly connected to the top of one of the L-shaped plates 3, and a touch rod 20 for touching the travel switch 19 is fixedly connected to the side wall of the clamping seat 8. The travel switch 19 is electrically connected to the electric telescopic cylinder 9 through a controller;

[0035] When the unloading mechanism drives the clamping seat 8 to move and drives the conical block 18 to clamp the pipe fitting, it will drive the touch rod 20 to touch the touch end of the travel switch 19, and then the travel switch 19 will transmit the signal to the controller, and then the controller controls the electric telescopic cylinder 9 to close, and at the same time controls the rotation motor 17 to start and the welding robot arm 2 to start, so as to realize the function of clamping the pipe fitting and automatically rotating the pipe fitting for welding.

[0036] In order to further improve the stability of the device during operation, the limiting mechanism includes a limiting tooth block 21, a limiting groove 22 is provided on the side wall of the sliding rod 10, a limiting plate 23 is slidably connected to the inner side of the limiting groove 22, the limiting tooth block 21 is fixedly connected above the limiting plate 23 and located below the gear 5, and a limiting spring 24 is fixedly connected between the bottom of the limiting groove 22 and the bottom of the limiting plate 23;

[0037] When the sliding rod 10 drives the moving tooth block 11 to slide out of the meshing position with the gear 5, it will drive the limit plate 23 to move below the gear 5, so that the limit tooth block 21 meshes with the gear 5, thereby limiting the rotation position of the gear 5. Then, when the sliding rod 10 continues to slide upward, the limit plate 23 is restricted by the gear 5 to slide in the limit groove 22, thereby gradually compressing the limit spring 24, thereby limiting the rotation position of the gear 5 without hindering the continued movement of the sliding rod 10.

[0038] In order to place the pipes after welding in sequence, a support frame 25 is fixedly connected to the bottom of the welding table 1 and extends a part backward, a pair of material guide plates 26 are fixedly connected to the rear side of the top of the welding table 1, a material plate 27 is provided on the top of the support frame 25, and a plurality of placement grooves 28 for placing pipes are equidistantly provided on the top of the material plate 27, racks 29 meshing with gears 5 are slidably connected to both sides of the top of the welding table 1, and an intermittent mechanism for intermittently pushing out the material plate 27 is provided below the welding table 1;

[0039] The intermittent mechanism includes a push rod 30, an L-shaped connecting plate 31 is fixedly connected to the side wall of the rack 29, a top plate 32 is fixedly connected to the rear side of the connecting plate 31, a moving plate 33 is slidably connected to the inner side of the support frame 25, a material plate 27 is placed on the top of the moving plate 33, a positioning plate 34 for pushing the material plate 27 is fixedly connected to the front side of the top of the moving plate 33, a slide groove 35 is penetrated on both sides of the support frame 25, and the slide groove 35 is used to avoid hindering the back and forth sliding of the push plate 36, a push plate 36 is fixedly connected to both sides of the moving plate 33 and is arranged through the slide groove 35, a plurality of push blocks 37 are fixedly connected to the top of the push plate 36 at equal distances, the push rod 30 is hingedly connected to the bottom of the top plate 32, an extrusion rod 38 is fixedly connected to the side wall of the push rod 30 and is against the bottom of the top plate 32,

[0040] During the operation of the feeding mechanism, when the feeding mechanism pushes out the welded pipe fittings, the pipe fittings will roll onto the guide plate 26 and then fall into the placement groove 28 on the material plate 27. Then the electric telescopic cylinder 9 will drive the sliding rod 10 to slide upward to drive the gear 5 to rotate in the opposite direction, thereby driving the meshing rack 29 at the bottom to move, and then drive the top plate 32 to slide through the connecting plate 31, and then drive the push rod 30 to slide. At this time, the extrusion rod 38 is resisted by the bottom of the top plate 32, which will limit the push rod 30 from flipping upward, and then push the push block 37 to drive the push plate 36 and the moving plate 33 to move. At the same time, the positioning plate 34 will push the material plate 27 to move, and the placement groove 28 where the pipe fittings have just been placed will be pushed out from under the guide plate 26, and the new placement groove 28 will be pushed out at the same time, so as to ensure that the pipe fittings can fall into the new placement groove 28 after the next welding is completed.

[0041] In order to facilitate the resetting of the movable plate 33, the length of the push rod 30 is longer than the length of the extrusion rod 38. Since the length of the push rod 30 is longer than the length of the extrusion rod 38, the weight of the push rod 30 is also heavier than the weight of the extrusion rod 38. Therefore, when the unloading mechanism pushes out the pipe fitting, the electric telescopic cylinder 9 will drive the top plate 32 and the push rod 30 to move backward. At this time, the push rod 30 will first be squeezed by the push block 37 to drive the extrusion rod 38 to flip. Then, when the push rod 30 moves out of the push block 37, the push rod 30 will lose its restriction because it is heavier than the extrusion rod 38. 0 will flip and reset, so it will not drive the movable plate 33 to slide, and the side wall of the push rod 30 is fixedly connected to the rotating rod 39. When the material plate 27 is full, the material plate 27 is first pulled out, and then the rotating rod 39 is pushed to drive the push rod 30 to flip to a certain angle, thereby releasing the position restriction of the push block 37, and the movable plate 33 can be pushed to slide and reset in the support frame 25. After the sliding is completed, the rotating rod 39 is released and the push rod 30 can flip and reset under its own gravity. Finally, a new material plate 27 is placed on the movable plate 33 to complete the replacement of the material plate 27.

[0042] In order to facilitate the use of a forklift to take out the material plate 27 filled with materials, a pair of sockets 40 for the insertion of a forklift are opened on the side wall of the material plate 27. Through the setting of the sockets 40, when the material plate 27 is full of pipes, the material plate 27 can be inserted from the movable plate 33 by using a forklift, thereby improving the convenience of the device during use.
