Description

Technical Field

[0001] This invention relates to the field of welding equipment technology, and specifically to a molybdenum wire laser cladding welding device. Background Technology

[0002] The molybdenum wire laser cladding welding device is a device that uses laser technology to perform cladding welding with molybdenum wire as the filler material. The laser beam generated by the laser generator is focused by the optical system and irradiates the surface of the workpiece to be welded. At the same time, the wire feeding system feeds the molybdenum wire into the laser action area. The high energy density laser beam causes the molybdenum wire and the base material on the workpiece surface to melt rapidly and form a molten pool. As the welding worktable moves or the workpiece rotates, the molten pool gradually cools and solidifies, thereby realizing the cladding welding between the molybdenum wire and the workpiece and forming a strong weld.

[0003] However, the existing technology has the following problems: In existing technologies, when performing large-area cladding welding on sheet metal, workers usually need to operate the welding machine in a zigzag back-and-forth motion to form a large cladding layer.

[0022] Further, please refer to Figure 9 -Figure 10 The clamping assembly 4 is used for clamping materials, and the clamping assembly 4 comprises two clamping rods 41, both of which are slidingly installed on the upper sliding table 33 and are mirror-imaged and located on the front and rear sides of the placement table 34 respectively. Two connecting rods 44 are hinged to the side of the clamping rod 41 away from the placement table 34, and a sliding rod 43 is hinged to the end of the two connecting rods 44 away from the clamping rod 41. The sliding rod 43 is slidingly connected with the upper sliding table 33, and a push rod 45 is connected to the side of the sliding rod 43 away from the placement table 34. Two push shafts 46 are connected to the operating table 1 and are located on the movement track of the two push rods 45 respectively. When the upper sliding table 33 moves to the left and is about to move to the initial position, the two push rods 45 can contact the two push shafts 46, the two push shafts 46 abut against the two push rods 45, the two push rods 45 are driven to stop moving respectively by the two push shafts 46, and the two connecting rods 44 drive the clamping rod 41 to move towards the sliding rod 43. When the upper sliding table 33 is located at the initial position, the two clamping rods 41 are away from the placement table 34 respectively. Two rebound seats 42 are connected to the side of the clamping rod 41 away from the placement table 34 through damping springs. The rebound seats 42 are connected with the upper sliding table 33. When the welding starts, the two push rods 45 gradually move away from the two push shafts 46, and the two clamping rods 41 move towards the placement table 34 respectively through the elastic force of the damping springs on the four rebound seats 42. A plurality of sliding shafts 47 are slidingly connected to the side of the clamping rod 41 close to the placement table 34, and springs are arranged between the sliding shafts 47 and the inner wall of the clamping rod 41. The clamping rod 41 is connected with a clamping block 48 at the end close to the placement table 34. When the clamping rod 41 is close to the placement table 34, the plurality of clamping blocks 48 contact the side wall of the plate. When the side wall of the plate is irregular, the protruding part of the side wall of the plate will extrude the contacted clamping block 48. The spring between the clamping rod 41 and the sliding shaft 47 enables the clamping block 48 to keep a certain pressure on the plate. The plurality of clamping blocks 48 adapt to the shape of the side wall of the plate and keep the adhesion to the side wall of the plate. Meanwhile, the plurality of clamping blocks 48 can also exert a certain pressure on the side wall of the plate, so that the plurality of clamping blocks 48 on both sides of the plate realize clamping of the plate through cooperation. Through the arrangement of the clamping assembly 4, the plurality of clamping blocks 48 on the two clamping rods 41 can cooperate to clamp plates of various specifications and shapes, improve the stability of the plate, avoid displacement of the plate during movement due to inertia, and thus affect the welding quality. Through the arrangement of the two sliding rods 43 and the four connecting rods 44, the two clamping rods 41 automatically approach the plate to realize clamping when the welding starts, and the two clamping rods 41 automatically move away from the plate to release the clamping after the welding is completed, so that the effect of automatic clamping is realized, and the automation level is further improved.

[0023] Further, please refer to Figure 11 - Figure 14The top-mounting assembly 5 is used to lift the material after welding is completed. The top-mounting assembly 5 includes a sector-shaped block 51, which is rotatably mounted on the inner wall of the platform 34. A portal-shaped rod 53 is slidably connected to the top surface of the upper slide 33. An abutment rod 52 is connected to the right side of the portal-shaped rod 53, and the abutment rod 52 slides in contact with the left side of the sector-shaped block 51. The portal-shaped rod 53 has two left ends. Two push rods 54 are connected to the operating table 1. The two push rods 54 are located on the movement trajectory of the two left ends of the portal-shaped rod 53. The width of the right end of the push rod 54 is greater than the width of the left end of the portal-shaped rod 53. When the upper slide 33 moves to the left and is about to reach the initial position, the two push rods 54... A push rod 54 abuts against the two left ends of the portal rod 53, stopping the portal rod 53 and the abutting rod 52 from moving. When the sector block 51 on the shelf 34 moves to the left, it is abutted by the abutting rod 52 and flips upward, causing the sector block 51 to protrude upward from the top surface of the upper slide table 33. The sector block 51 lifts the left half of the board, creating a gap between the board and the shelf 34, making it easier for staff to place and retrieve the board. Two centering frames 55 are rotatably mounted on the shelf 34. The two centering frames 55 are mirror images of each other. Two protrusions 56 are connected to the outer wall of the sector block 51. A fixing block 57 is connected to the left side of the centering frame 55. The left end of the fixing block 57 is hinged. A lever 58 is attached, with a limit rod between the bottom of the lever 58 and the bottom of the fixed block 57. A spring is installed between the lever 58 and the fixed block 57. The lever 58 can only rotate upwards on the fixed block 57, not downwards. After rotating upwards, the lever 58 can be reset by the spring force. When moving, the two protrusions 56 slide in contact with the two levers 58 respectively. When the two protrusions 56 move downwards, they contact the two levers 58 and drive the two fixed blocks 57 downwards. The two fixed blocks 57 cause the two centering brackets 55 to tilt away from each other on the side furthest from each other. After the two protrusions 56 disengage from the two levers 58, the two... The centering frame 55 is reset by gravity, allowing the two centering frames 55 to tilt upwards from the front and rear sides of the plate. The two centering frames 55 move synchronously in a clamping motion, so that the bottom edges of the front and rear sides of the material are subjected to the same pushing force at the same time. When the material tilts, the two centering frames 55 can center and straighten the material through the above movement, so as to avoid the material tilting and affecting the welding operation. By setting the two centering frames 55, the two centering frames 55 tilt upwards at the same time when the plate begins to move to the right. By moving the front and rear edges of the plate, a certain centering and straightening effect is achieved, so as to avoid the plate being placed crookedly and affecting the welding operation.

[0024] Using the above structure, the working principle of this case is as follows: the welding head of welding machine 2 can be adjusted in three axes, that is, in six directions: forward, backward, left, right, up, and down. Before welding, the operator adjusts the position of the welding head according to the actual welding requirements. When welding the plate, the plate is placed on the platform 34. The anti-slip strip on the platform 34 can provide a certain degree of anti-slip effect. After adjusting the welding head to the left side of the welding position, welding machine 2 and hydraulic cylinder 31 are started. Hydraulic cylinder 31 drives the lower slide 32 to move to the right. The lower slide 32 drives the upper slide 33 to move to the right. The upper slide 33 can only move forward and backward on the lower slide 32. When moving to the right, the ball nut seat 36 moves to the right. As the ball nut seat 36 moves on the ball screw 35, it rotates via the ball thread connection. During its rotation, the ball nut seat 36 drives the rotating wheel 38 to rotate through the meshing of the first gear ring 37 and the second gear ring 39. The rotating wheel 38 drives the roller 311 to revolve around the roller 38. As the roller 311 revolves, it drives the slide frame 314 to reciprocate back and forth via the slide groove on the slide frame 314. The slide frame 314 drives the upper slide table 33 and the shelf 34 above it to reciprocate back and forth. Therefore, the shelf 34 and the plate above it can... While moving to the right, the upper slide 33 moves back and forth, while the welding head remains stationary. Therefore, during the movement of the plate, the weld seam at the welding point forms a large area of ​​cladding layer in a back-and-forth zigzag pattern, achieving automatic welding. The operation is simple, and the movement trajectory of the welding area maintains a high degree of regularity, resulting in high welding precision and preventing missed welds. The length of the welding area is the distance the upper slide 33 moves to the right. After welding is completed, the hydraulic cylinder 31 drives the lower slide 32 to reset to the left. After the lower slide 32 returns to its initial position, the welded plate is removed. Adjustment of the welding area is required. When the width is adjusted, an electric screwdriver is used to rotate the worm 313 through the cross groove on the worm 313. When the worm 313 rotates, it drives the first adjusting screw 310 to rotate through the worm wheel 312. When the first adjusting screw 310 rotates, it drives the roller 311 to move on the axis of the first adjusting screw 310 through the threaded connection, thereby adjusting the distance between the roller 311 and the center of the rotating wheel 38. Adjusting the distance between the roller 311 and the center of the rotating wheel 38 can adjust the distance of the slide frame 314 to move back and forth, thereby adjusting the amplitude of the back and forth movement of the platform 34 to achieve the adjustment of the width of the welding area of ​​the plate.When welding pipes is required, the welding path is typically threaded. The worker places the left end of the pipe against the first cone 315 and rotates the second adjusting screw 319 via handwheel. This causes the mounting block 317 to slide to the left on the slide block 316 via its threaded connection. The mounting block 317 then moves the second cone 318 to the left, pressing the right end of the pipe against it. The first and second cones 315 and 318 clamp the pipe in place. After the lower platform 32 begins to move to the right, the rotating wheel 38 rotates, causing the first cone 315 to rotate. The first cone 315 then rotates the pipe and the second cone 318, causing the pipe to rotate while moving to the right. The welding head forms a tightly connected spiral weld on the pipe, resulting in a large-area cladding layer. The displacement component 3 allows the platform 34 to... While moving the plate to the right, it can also reciprocate back and forth, causing the weld to form a large-area cladding layer in a zigzag pattern. Before welding, the operator only needs to adjust the welding head position of welding machine 2. The welding operation is completed automatically, making it simple and convenient to operate, with high welding precision, avoiding missed welds that can occur with manual operation. The first adjusting screw 310 allows the operator to adjust the distance between the roller 311 and the center of the rotating wheel 38, thereby adjusting the amplitude of the reciprocating movement of the platform 34 and thus adjusting the width of the welding area to meet different welding requirements. The first and second cones 315 and 318 can clamp the pipe, achieving cladding welding by rotating the pipe, thus meeting the operator's welding needs and expanding the processing range.

[0025] The clamping rod 41 can only slide back and forth on the upper slide table 33. The length of the two levers 45 is greater than the length of the upper slide table 33's back and forth movement. When the upper slide table 33 moves to the left and is about to reach the initial position, the two levers 45 can contact the two lever shafts 46. The two lever shafts 46 abut against the two levers 45, causing the two levers 45 to drive the two slide rods 43 to stop moving. Meanwhile, the two clamping rods 41 continue to move to the left with the upper slide table 33. Taking the front clamping rod 41 as an example, when the clamping rod 41 continues to move to the left, the two connecting rods 44 tilt because their front ends remain stationary while their rear ends move to the left, causing the two connecting rods 44 to drive the clamping rod 41 to stop moving. The upper slide 33 moves towards the slide bar 43, thus achieving the effect of moving the two clamping rods 41 away from each other. When the upper slide 33 is in the initial position, the two clamping rods 41 are away from the platform 34. When welding begins, the upper slide 33 moves to the right, and the two levers 45 gradually disengage from the two lever shafts 46. The two clamping rods 41 move towards the platform 34 through the elastic force of the damping springs on the four return seats 42. The two slide bars 43 and the four connecting rods 44 also return to their original positions, thus achieving the effect that the two clamping rods 41 are away from the platform 34 in the initial position and move closer to the platform 34 after welding begins. When the clamping rod 41 approaches the shelf 34, multiple clamping blocks 48 contact the side wall of the board. When the side wall of the board is irregular, the protruding part of the side wall will squeeze the contacting clamping block 48, causing the clamping block 48 to drive the sliding shaft 47 to retract inward towards the clamping rod 41. The spring between the clamping rod 41 and the sliding shaft 47 keeps the clamping block 48 under a certain pressure on the board. The multiple clamping blocks 48 adapt to the shape of the side wall of the board, maintaining a close fit with the side wall of the board. At the same time, the multiple clamping blocks 48 can also apply a certain pressure to the side wall of the board, so that the multiple clamping blocks 48 on both sides of the board achieve clamping of the board through cooperation. The four damping springs can also... The clamping mechanism undergoes a certain degree of deformation during clamping to accommodate plates of various specifications. The clamping assembly 4 allows multiple clamping blocks 48 on the two clamping rods 41 to cooperate in clamping plates of various specifications and shapes, improving plate stability and preventing displacement due to inertia during movement, which could affect welding quality. The two sliding rods 43 and four connecting rods 44 automatically bring the two clamping rods 41 closer to the plate for clamping when welding begins, and automatically release the clamps after welding, achieving automatic clamping and further enhancing automation.

[0026] As the upper slide 33 moves to the left and is about to reach its initial position, the width of the right end of the push rod 54 is greater than the width of the left end of the portal rod 53. The two push rods 54 abut against the two left ends of the portal rod 53, stopping the portal rod 53 and the abutting rod 52 from moving. The upper slide 33 and the shelf 34 continue to move to the left. When the sector block 51 on the shelf 34 moves to the left, it is abutted by the abutting rod 52 and flips upward, causing the sector block 51 to protrude upward from the top surface of the upper slide 33. Therefore, when the upper slide 33 is in its initial position, the sector block 51 protrudes from the top surface of the shelf 34. When placing the board, the worker places the left half of the board on the sector block 51. Because the sector block 51 lifts the left half of the board, the board and the shelf 34 are separated. A gap is formed to facilitate placement by workers. After welding, when the platform 34 returns to its leftward position, the sector block 51 lifts the left half of the plate, making it easier for workers to pick up. When the platform 34 and the upper slide 33 move to the right, the gate rod 53 gradually disengages from the two push rods 54. The sector block 51 returns to its downward position by gravity, simultaneously driving the abutment rod 52 and the gate rod 53 to return to their leftward position. After returning to its downward position, the sector block 51 does not protrude from the top surface of the platform 34, allowing the plate to be placed flat on the platform 34. When the sector block 51 returns to its downward position, it drives the two protrusions 56 to move downward. Due to the limitation of the lower limit rod, the lever 58 can only rotate upward on the fixed block 57 and cannot rotate downward. After rotation, the spring force allows it to return to its original position. When the sector block 51 moves the two protrusions 56 upward, the protrusions 56 push the lever 58 upward. The lever 58 does not move the fixed block 57. Therefore, when the two protrusions 56 move downward, they contact the two levers 58 and drive the two fixed blocks 57 downward. The two fixed blocks 57 cause the two centering frames 55 to tilt away from each other on one side. After the two protrusions 56 disengage from the two levers 58, the two centering frames 55 return to their original position by gravity, allowing them to tilt upward from the front and rear sides of the material. The two centering frames 55 move in a synchronous clamping motion, so that the bottom edges of the front and rear sides of the material are simultaneously subjected to the same pushing force. When the material tilts... The two centering frames 55, through the aforementioned movements, can center and straighten the material, preventing it from tilting and affecting the welding operation. The movements of the fan-shaped block 51 and the two centering frames 55 all occur before the multiple clamping blocks 48 come into contact with the material, without affecting the clamping of the material. Through the setting of the top material component 5, the fan-shaped block 51 can lift the plate upward after welding, creating a gap between the plate and the platform 34, making it easier for workers to pick up and place the next plate. Through the setting of the two centering frames 55, the two centering frames 55 tilt upward simultaneously once when the plate begins to move to the right. By moving the front and rear edges of the plate, a certain centering and straightening effect is achieved, preventing the plate from being placed crookedly and affecting the welding operation.
