Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of ball joint railing welding, in particular to a ball joint railing side plate double-station welding equipment. BACKGROUND

[0002] The ball joint railing (inclined column type) is a protective railing with a spherical connector as the core. The column is installed at an inclined angle. The structure is composed of a ball joint, an inclined column, a horizontal rod, a handrail, etc. The ball precisely connects each component to form a stable frame. The railing has both protective and aesthetic properties. The inclined column design enhances lateral stress stability. It is suitable for platforms, staircases, and boardwalks. The material is usually carbon steel (zinc-plated / sprayed) or stainless steel, which is corrosion-resistant, easy to maintain, easy to install, and can be adjusted as needed. It is widely used in industrial, municipal, and landscape fields.

[0003] The welding quality directly affects safety and durability. Traditional ball joint railing welding mainly relies on manual operation, which has low efficiency, high labor intensity, and poor consistency. Therefore, the existing technology uses automated equipment to position and lock the steel pipe and steel ball using a tool clamp, and then uses a welding robot to weld the steel ball and steel pipe together.

[0004] Traditional welding equipment needs to lock the steel pipe and steel ball using a clamp after loading, and then weld them. After welding, the welded ball joint railing needs to be removed and a new steel pipe and steel ball need to be fixed, which makes the welding efficiency very low. Therefore, we propose a ball joint railing side plate double-station welding equipment. SUMMARY

[0005] The purpose of the present application is to provide a ball joint railing side plate double-station welding equipment. By setting the first and second moving plates for installing tool clamps, the steel pipe and steel ball can be aligned and fixed, and a welding robot can be used for welding. The first moving plate can move forward and backward, and the second moving plate can move forward and backward and vertically. This allows one of the moving plates to lock the steel pipe and steel ball and be placed at the front end for welding, while the other moves to the rear end for removing the ball joint railing and fixing the new steel pipe and steel ball.

DETAILED DESCRIPTION

[0038] Please refer to Figures 1-4 The application provides a technical scheme: a ball jointed railing side plate double-station welding device, which comprises a workbench 1 and a welding mechanical arm arranged at the front end of the workbench 1, and supporting legs 13 are arranged at the bottom of the four corners of the workbench 1, the four supporting legs 13 have the same height, and the horizontal support of the workbench 1 in the transverse direction is realized, and at least one welding mechanical arm is arranged at the front end of the workbench 1, so that the steel pipe fixed above the workbench 1 and the steel ball aligned with the steel pipe can be welded to produce a ball jointed railing.

[0039] An opening 11 penetrating through the upper and lower surfaces of the workbench 1 is arranged on the surface of the workbench 1, first side plates 5 are vertically welded and fixed at the front and rear ends of the workbench 1 below the opening 11, first screw rods 51 are longitudinally and rotatably arranged between the first side plates 5 at the front and rear ends, the two first screw rods 51 are parallel to each other, the two screw rods are arranged below the workbench 1 at the two sides of the opening 11, the first screw rod 51 is in transmission connection with a first stepping motor 52 arranged on the surface of the first side plate 5 at the front end of the workbench 1, and the first stepping motors 52 at the two sides are connected to the same industrial computer, so that the two first stepping motors 52 can be synchronously controlled and the screw rods can be synchronously driven to rotate.

[0040] The front end of the opening 11 is internally transversely provided with a first moving plate 2, the lower sides of the first moving plate 2 are fixed with first screw sleeves 211 through connecting plates 21, the first screw sleeves 211 are sleeved on the outer rings of first lead screws 51 through screwing, the surfaces of the first moving plate 2 are provided with mounting screw holes 4, a plurality of mounting screw holes 4 are uniformly arranged, in use, tool clamps can be mounted on the surface of the first moving plate 2 through the mounting screw holes 4, the steel pipes and the steel balls can be fixed, the ends of the steel pipes are aligned with the steel balls, the first moving plate 2 can be driven to the front end by the two synchronously rotating first lead screws 51, then the steel pipes and the steel balls are welded by the welding mechanical arm, and the ball-shaped railings are processed, after welding, the two first lead screws 51 are synchronously rotated again to drive the first moving plate 2 to the rear end, then the workers can unload the welded ball-shaped railings at the rear end, and new steel pipes and steel balls are fixed on the upper surface of the first moving plate 2 by tool clamps, and the first moving plate 2 can drive the steel pipes and the steel balls to the front end for welding processing again.

[0041] Because the first moving plate 2 is moved to the rear end for unloading and reloading, the welding mechanical arm is always in a shutdown state, a lot of time is wasted, and the efficiency is low, therefore, the application also makes the following improvements:

[0042] A second moving plate 3 is also transversely arranged inside the rear end of the opening 11, the size of the second moving plate 3 is the same as that of the first moving plate 2, and similarly, the surfaces of the second moving plate 3 are provided with mounting screw holes 4, a plurality of mounting screw holes 4 are uniformly arranged, in use, tool clamps of the same specification can be mounted on the surface of the second moving plate 3 through the mounting screw holes 4, and the steel pipes and the steel balls can be fixed, and the ends of the steel pipes are aligned with the steel balls.

[0043] A transmission plate 6 parallel to the second moving plate 3 is transversely arranged below the second moving plate 3, second side plates 7 are vertically fixed to the bottom of the workbench 1 at the front end and the rear end below the middle position of the transmission plate 6, a second lead screw 71 is longitudinally rotatably arranged between the second side plates 7, the second lead screw 71 is in transmission connection with a second stepping motor 72 arranged on the surface of the front end second side plate 7, a second screw sleeve 63 is fixed below the middle position of the transmission plate 6, the second screw sleeve 63 is sleeved on the outer ring of the second lead screw 71 through screwing, a first electric push rod 61 is vertically arranged above the middle position of the transmission plate 6, and the top of the extending end of the first electric push rod 61 is fixed to the bottom of the second moving plate 3.

[0044] Through the additional setting of the above structure, when the first moving plate 2 is placed at the front end to perform the welding work of the ball jointed rail, the second moving plate 3 is located at the rear end, the steel pipe and the steel ball can be fixed above the second moving plate 3 by using the tool clamp during welding, and the steel pipe and the steel ball are aligned. When the welding of the ball jointed rail on the surface of the first moving plate 2 is completed, the first moving plate 2 drives the ball jointed rail to move backward. At this time, the first electric push rod 61 first drives the second moving plate 3 and the steel pipe and the steel ball fixed on the surface of the second moving plate 3 to lower the height, and then the second step motor 72 drives the second lead screw 71 to rotate, so that the second moving plate 3 driven by the second lead screw 71 moves to the front end, and then the first electric push rod 61 drives the second moving plate 3 and the steel pipe and the steel ball on the surface of the second moving plate 3 to rise in height. Subsequently, the welding work can be performed on the surface of the second moving plate 3 at the same time, and the unloading and loading work can be performed above the first moving plate 2. When the welding of the ball jointed rail on the surface of the second moving plate 3 is completed, the second moving plate 3 drives the ball jointed rail to lower the height and move backward. The second moving plate 3 drives the steel pipe and the steel ball to move forward, and then the second moving plate 3 rises in height to unload the ball jointed rail and fix the steel pipe and the steel ball, and simultaneously performs the welding work on the steel pipe and the steel ball on the surface of the first moving plate 2. Thus, the welding mechanical arm does not need to stop and wait for unloading and loading, and the welding efficiency is greatly improved.

[0045] The guide cylinder 62 is vertically fixed above the transmission plate 6 on both sides of the first electric push rod 61, and the guide rod 31 is vertically fixed below the second moving plate 3 above the guide cylinder 62. The guide rod 31 can only slide into the inside of the guide cylinder 62 above. When the first electric push rod 61 drives the second moving plate 3 to rise or lower in height, the guide rod 31 below rises or lowers in height in the guide cylinder 62, thereby playing a stable guiding role when the second moving plate 3 rises or lowers.

[0046] In addition, the third side plate 8 is vertically welded and fixed at the front end and the rear end of the workbench 1 on both sides of the second lead screw 71, the front and rear third side plates 8 are parallel to each other, and the longitudinal slide rod 81 is fixed below the transmission plate 6 on both sides of the second lead screw 71 through the third side plate 8. The height of the slide rod 81 is the same as the height of the second lead screw 71, and the slide rod 81 is parallel to the second lead screw 71. The slide sleeve 64 is welded and fixed at the bottom of the transmission plate 6 on both sides, and the slide rod 81 on both sides can slide through the slide sleeve 64 fixed below the transmission plate 6 on both sides. When the transmission plate 6 moves forward and backward, the slide sleeve 64 slides forward and backward outside the slide rod 81, thereby playing a stable guiding role when the transmission plate 6 slides forward and backward.

[0047] Since the welding work and the unloading / loading work are carried out simultaneously, the light during welding can cause damage to the glasses of the operator, therefore, the application is provided with a light shielding plate 9 above the rear end of the workbench 1, the light shielding plate 9 is perpendicular to the surface of the workbench 1, a through opening 91 is formed in the middle of the light shielding plate 9, the width of the opening 91 is equal to the width of the opening 11, in addition, the front end of the light shielding plate 9 on both sides is welded with a mounting plate 92 below, the mounting plate 92 is perpendicular to the surface of the light shielding plate 9, the surface of the workbench 1 below the mounting plate 92 is provided with two connecting screw holes 12, then the bolt is penetrated through the mounting plate 92 and screwed into the connecting screw hole 12, so that the mounting plate 92 can be detachably mounted on the surface of the workbench 1, thereby realizing the mounting and fixing of the light shielding plate 9.

[0048] In use, the light shielding plate 9 blocks the light during welding to avoid damage to the eyes of the workers, and the opening 91 is used to make the tool clamp mounted on the surface of the first moving plate 2 and the fixed steel pipe and steel ball pass through, which will not be blocked by the light shielding plate 9.

[0049] Embodiment two

[0050] After the light shielding plate 9 of embodiment one is set, the opening 91 is convenient for the tool clamp and the steel pipe and steel ball on the surface of the first moving plate 2 to pass through, but there is a light leakage at the opening 91, which is not enough for the protection of the workers, therefore, another embodiment is provided, please refer to Figure 5 The difference between the embodiment one and the embodiment two is only that:

[0051] The mounting plate 92 below both sides of the light shielding plate 9 is replaced by a support plate 93 which is fixed perpendicularly to the light shielding plate 9, the support plate 93 is supported on the surface of the workbench 1, and the second electric push rod 94 is vertically installed on the bottom of the workbench 1 below the support plate 93, the extension end of the second electric push rod 94 is fixed to the bottom of the support plate 93, and the second electric push rods 94 on both sides are connected to the same industrial computer, so that the two second electric push rods 94 can be controlled synchronously and drive the light shielding plate 9 to rise and fall, when the welding work and the unloading / loading work are carried out, the light shielding plate 9 can have a better light shielding effect, when the first moving plate 2 and the second moving plate 3 are alternately positioned, the second electric push rod 94 drives the support plate 93 and the light shielding plate 9 to rise in height, so that the first moving plate 2 and the tool clamp, the steel pipe and the steel ball above the first moving plate 2 can pass through, after the position is alternated, the second electric push rod 94 drives the light shielding plate 9 to fall in height again.
