Description

Technical Field

[0001] The present invention belongs to the field related to welding processing technology, and more specifically relates to an intelligent positioning welding device for processing road safety guardrails. Background Art

[0002] The intelligent positioning welding device is a device used in the process of road safety guardrail processing to perform welding and fixing operations between the frame and mesh plate of the road safety guardrail. It can be used to quickly locate the weld position of the road safety guardrail, so that the welding gun can be moved accurately along the weld, thereby completing the welding and fixing of the road safety guardrail.

[0003] The application document with publication number CN115502628A records a welding device for a safety guardrail, including a base, a support arm is symmetrically and vertically fixedly connected to the top of the base, a fixed frame is rotatably connected between the two support arms through a rotating shaft, and a crossbeam placement seat is symmetrically and movably arranged on the front and rear sides inside the fixed frame, a vertical rib placement groove is opened in the middle position of the fixed frame, and a number of vertical rib placement grooves are opened side by side with equal intervals, and a vertical rib pushing assembly is movably arranged in the fixed frame on one side of each vertical rib placement groove, eliminating the need for personnel to manually overlap the safety guardrail structure, which is more labor-saving and efficient. At the same time, by adjusting the overlapped safety guardrail to a vertical state, it is also convenient for personnel to weld both sides of the safety guardrail, eliminating the need for personnel to manually flip the safety guardrail, which is more convenient.

[0004] The above-mentioned equipment has certain shortcomings when the welding device is used. The above-mentioned welding device can only use the welding operation of the conventional guardrail structure. The guardrail in the present application is mainly composed of two parts: a frame and a mesh plate. The mesh plate is smaller than the frame. During the welding operation, the mesh plate needs to be pressed against the frame, and the welding gun needs to be moved around the mesh plate and the frame, while keeping the same spacing around the mesh plate and the frame, so that the mesh plate and the frame can maintain the same welding strength around them during welding. When the spacing is small, it cannot meet the welding requirements, which reduces the welding strength of this part. Manual installation and positioning makes the mesh plate more prone to misalignment than the frame, and the mesh plate and the frame cannot maintain the same spacing around them, thereby affecting the welding effect around the mesh plate and the frame; secondly, the welding of the guardrail structure requires moving around the mesh plate and the frame, and the welding of its four sides requires the welding gun to move four times. The traditional welding device does not have a two-way welding structure, and cannot simultaneously complete the two-way welding operation of the mesh plate and the frame, reducing its welding efficiency. Summary of the invention

[0005] The purpose of the present invention is to provide an intelligent positioning welding device for processing road safety guardrails, which can solve the existing problems.

[0006] The problem to be solved by the present invention is:

[0007] 1. The above welding device can only be used for welding operations of conventional guardrail structures. The guardrail in this application is mainly composed of a frame and a mesh plate. The mesh plate is smaller than the frame. During the welding operation, the mesh plate needs to be pressed against the frame, and the welding gun needs to be moved around the mesh plate and the frame. At the same time, the mesh plate and the frame are kept at the same distance. Only in this way can the mesh plate and the frame be kept at the same welding strength during welding. When the distance is small, the welding requirements cannot be met, and the welding strength of this part is reduced. The manual installation and positioning makes the mesh plate more prone to misalignment than the frame, and the mesh plate and the frame cannot be kept at the same distance, thereby affecting the welding effect around the mesh plate and the frame.

[0008] 2. Secondly, the welding of the guardrail structure requires movement around the mesh and the frame. The welding of the four sides requires the welding gun to move four times. The traditional welding device does not have a bidirectional welding structure and cannot complete the bidirectional welding operation of the mesh and the frame at the same time, reducing its welding efficiency.

[0009] The purpose of the present invention can be achieved through the following technical solutions:

[0010] An intelligent positioning welding device for processing road safety guardrails comprises a fixed base and a sliding frame, wherein the sliding frame is movably mounted on the outer surface of the upper end of the fixed base, a connecting frame is movably mounted on the inner side of the sliding frame, and two groups of welding guns are slidably mounted on the bottom of the connecting frame, four groups of fixed clamps are movably mounted on the upper part of the fixed base, and the four groups of fixed clamps are distributed in a cross shape, the fixed clamps comprise vertical clamps for fixing the frame and horizontal top blocks for fixing the mesh plate, the horizontal top blocks are movably mounted on the inner side of the vertical clamps, a sliding base for cooperating with the connecting frame is movably mounted on the outer surface of the sliding frame, and the sliding base and the connecting frame are movably connected via a lifting rod.

The bottom of the vertical clamp is fixedly installed with a threaded slider used in conjunction with the bidirectional screw rod, and the two groups of bidirectional screw rods are staggered in an upper and lower cross shape. When the two groups of fixed clips are moved, the motor and gears are used to drive the bidirectional screw rod to rotate, so that the two groups of fixed clips on the bidirectional screw rod move toward each other, so that the vertical clamp abuts against the side of the frame, and one end of the horizontal top block abuts against the side of the mesh plate.

[0012] As a further technical solution of the present invention, the transverse top block and the vertical clamp are locked and fixed by a fastening bolt, and the outer surface of the transverse top block is movably sleeved with a lifting slide frame used in conjunction with the fastening bolt, and the lifting slide frame is movably sleeved on the inner side of the vertical clamp. The height of the transverse top block can be adjusted by moving the lifting slide frame up and down in the vertical clamp, and the position of one end of the transverse top block can be adjusted by moving the transverse top block in the lifting slide frame, so that the transverse top block can be adjusted arbitrarily according to the height and size of the mesh plate when in use.

[0013] As a further technical solution of the present invention, a fastening pad is provided at one end of the fastening bolt, and a sliding pad is provided at the other end of the fastening bolt, and a docking groove used in conjunction with the sliding pad is provided on the inner side of the transverse top block. When the user rotates the fastening bolt, it is locked between the fastening pad and the lifting slide frame through the vertical clamp, and the transverse top block is locked between the sliding pad and the lifting slide frame, thereby completing the bidirectional fixing operation of the transverse top block.

[0014] As a further technical solution of the present invention, the connecting frame and the welding gun are slidably connected by a movable slider. The inner side of the connecting frame is provided with a movable slide groove used in conjunction with the movable slider. The welding gun and the movable slider are locked and fixed by a bolt. In order to meet the two-way welding operation of road safety guardrails of different sizes, the positions of the two groups of welding guns can be moved arbitrarily by setting the movable slider. When the two groups of welding guns move, the welding operation of the two groups of gaps between the frame and the mesh plate can be met.

[0015] As a further technical solution of the present invention, two groups of limit slots are provided on the outer surface of the upper end of the connecting frame, and four groups of lifting rods are movably installed on the bottom of the sliding base. The lifting rods are connected to the limit slots, which can play an auxiliary fixing role when the connecting frame moves, and at the same time reinforce the rotating connecting frame. When the connecting frame rotates ninety degrees, the lifting rods can be inserted into the corresponding limit slots to play a fixing role.

[0016] As a further technical solution of the present invention, the upper end of the lifting rod and the sliding base are movably connected via a bearing, a gear ring is fixedly sleeved on the upper outer surface of the lifting rod, a gear wheel is movably installed on the lower part of the sliding base, the gear ring and the gear wheel are meshed with each other, the lifting rod itself is a telescopic structure, so that the lifting rod can move up and down, the lifting rod can be driven by a pneumatic structure, and the setting of the gear ring and the gear wheel, in conjunction with the setting of the bearing structure, the lifting rod can be rotated, the gear wheel is driven by a motor, so that the gear wheel drives the gear ring, thereby driving the lifting rod to rotate, and driving the connecting frame to adjust the angle, thereby adjusting the welding position of the two sets of welding guns.

[0017] As a further technical solution of the present invention, a driving wheel is movably installed on the inner side of the sliding base, and a rack is provided on the outer surface of the upper end of the sliding frame for cooperating with the driving wheel. The rack and the driving wheel are meshed with each other, and the driving wheel is driven to rotate by a motor, so that the driving wheel drives the sliding base to move under the action of the rack, thereby moving the welding gun.

[0018] As a further technical solution of the present invention, the lower end of the sliding frame and the fixed base are driven by two adjusting screw rods, and the two adjusting screw rods are connected by a chain transmission. A motor is used to drive one adjusting screw rod, and the two adjusting screw rods rotate synchronously under the action of the chain. The ends of the two adjusting screw rods are installed with tooth caps for use with the chain.

[0019] As a further technical solution of the present invention, a movable sleeve used in conjunction with the direction-adjusting screw rod is fixedly mounted on the outer surface of the lower end of the sliding frame, and a sliding groove used in conjunction with the sliding frame is provided on the upper end of the fixed base.

[0020] Beneficial effects of the present invention:

[0021] 1. By setting the fixing clamps, when the intelligent positioning welding device for road safety guardrail processing is used, it can meet the two-way fixing adjustment of the frame and the mesh plate, so that the frame and the mesh plate are kept at the same distance around, avoiding the tilting phenomenon and improving the welding effect;

[0022] During operation, the user stacks the screen plate and the frame on the upper end of the fixed base, and the two sets of bidirectional screw rods are staggered in an upper and lower cross shape. When the two sets of fixed clamps are moved, the motor and the gear are used to drive the bidirectional screw rod to rotate, so that the two sets of fixed clamps on the bidirectional screw rod move toward each other, so that the vertical clamps abut against the side of the frame, and one end of the horizontal top block abuts against the side of the screen plate, and the horizontal top block can be adjusted twice according to the height and size of the screen plate. The up and down movement of the lifting slide frame in the vertical clamp can meet the height adjustment of the horizontal top block, and the movement of the horizontal top block in the lifting slide frame can adjust the position of one end of the horizontal top block, so that the horizontal top block can be arbitrarily adjusted according to the height and size of the screen plate when in use. When the four sets of fixed clamps complete the positioning operation, the four sets of vertical clamps are clamped on the side of the frame, and the horizontal top block is synchronously clamped on the side of the screen plate, so that the screen plate and the frame are in a cross shape. Figure 7 As shown in the figure, the mesh plate is located in the middle position of the frame, and the mesh plate and the frame are kept at the same distance on all sides. When the welding gun is moving for welding, a reasonable welding position is reserved for the welding gun. When the user rotates the fastening bolt, it is locked between the fastening pad and the lifting slide frame through the vertical clamp, and the horizontal top block is locked between the sliding clamp pad and the lifting slide frame, thereby completing the two-way fixing operation of the horizontal top block.

[0023] 2. By setting up a connecting frame and a sliding frame, when the intelligent positioning welding device for processing road safety guardrail is used, it can simultaneously complete the mobile welding operation of two sets of welds, thereby improving the welding efficiency of the road safety guardrail;

[0024] When in use, in order to meet the two-way welding operation of road safety guardrails of different sizes, the positions of the two sets of welding guns can be moved arbitrarily by setting a movable slider, and the slider and the connecting frame are locked and fixed by using a bolt. When the two sets of welding guns move, the welding operation of the two sets of gaps between the frame and the mesh plate can be met. The lifting rod itself is a telescopic structure, so that the lifting rod can move up and down. The lifting rod can be driven by a pneumatic structure, and the setting of the gear ring and the gear wheel, in conjunction with the setting of the bearing structure, allows the lifting rod to rotate. The gear wheel is driven by a motor, so that the gear wheel drives the gear ring, thereby driving the lifting rod to rotate, and driving the connecting frame to adjust the angle, thereby adjusting the two sets of welding guns. The welding position is set, and the lifting rod is used to drive the connecting frame to move downward, so that the two groups of welding guns on the connecting frame are abutted against the upper part of the frame and the mesh plate. First, the motor is used to drive the driving wheel to rotate, so that the driving wheel drives the sliding base to move under the action of the rack, and the welding gun is moved to complete the unidirectional movement of the welding gun. After the welding gun completes the position adjustment by using the rotating structure, the motor is used to drive a direction adjustment screw rod, and the two direction adjustment screw rods are rotated synchronously under the action of the chain. Under the action of the moving sleeve, the sliding frame is driven to translate as a whole to complete the two-way position adjustment of the welding gun. The two groups of welding movements of the welding gun can make the two groups of welding guns complete the welding operation of four welds, thereby improving the welding efficiency.

[0025] 3. By setting a lifting rod, when the intelligent positioning welding device for road safety guardrail processing is used, the use of the connecting frame is optimized, the structural strength after rotation adjustment is improved, and the welding stability is improved;

[0026] During operation, the lifting rod is connected to the limit slot, which can assist in fixing the connecting frame when it moves, and at the same time reinforce the rotating connecting frame. When the connecting frame is rotated ninety degrees, the lifting rod can be inserted into the corresponding limit slot to fix it, thereby preventing the connecting frame from shaking during mobile welding operations.

When the connecting frame 5 is rotated ninety degrees, the lifting rods 23 can be inserted into the corresponding limit slots 19 to play a fixing role.

[0044] The upper end of the lifting rod 18 and the sliding base 6 are movably connected to each other through a bearing.

The toothed ring 28 and the toothed wheel 22 are meshed with each other. The lifting rod 18 itself is a telescopic structure, so that the lifting rod 18 can move up and down. The lifting rod 18 can be driven by a pneumatic structure, and the setting of the toothed ring 28 and the toothed wheel 22, in conjunction with the setting of the bearing structure, allows the lifting rod 18 to rotate.
