Technical Field

A workbench surface is connected to the top of the base cabinet. A laser welding machine is installed at the rear side of the top of the workbench surface. Positioning blocks for positioning the frame of the drain rack are symmetrically connected to the front and back on both the left and right sides of the top of the workbench surface. Through the cooperation of the guide groove and the sliding rod A, this application can loosen the bars of the drain rack when the loading hopper moves backward, and the bars of the drain rack can be put into the receiving groove one by one to be对接 with the frame of the drain rack, quickly completing the loading of the bars, thereby improving the processing efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0027] In order to make the technical means, creative features, achieved objectives and effects realized by the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0028] As Figures 1 to 3 shown, a laser welding machine for hardware parts according to an embodiment of the present invention includes a welding machine base 1; one end of the welding machine base 1 is fixedly connected with an electric turntable 11; the output end of the electric turntable 11 is fixedly connected with a telescopic frame 12; a welding frame 13 is arranged outside the telescopic frame 12; a sliding frame 14 is slidably connected to the inner wall of the welding frame 13 through a first electric slider; a laser welding head 15 is fixedly connected to the end of the sliding frame 14; a connecting component is arranged between the telescopic frame 12 and the welding frame 13, and the connecting component is used to adjust the laser welding angle of the laser welding head 15; when laser welding a U-shaped special-shaped hardware part, first, the three hardware plates of the U-shaped hardware part are assembled into a U shape on the welding machine base 1, and the assembled hardware plates are fixed and limited. Subsequently, the output end of the electric turntable 11 drives the telescopic frame 12 to rotate the angle. The telescopic frame 12 can be telescoped up and down at the output end of the electric turntable 11, so that the laser welding head 15 installed by the connecting component can approach the inner joint seam formed by the hardware plates. Since the inner joint seam of the U-shaped hardware part is relatively deep, at this time, the first electric slider drives the sliding frame 14 to slide out on the inner wall of the welding frame 13, adjusting the distance between the laser welding head 15 and the inner joint seam, so that the laser welding head 15 can be attached to the inner joint seam of the U shape for welding. The laser welding head 15 starts welding from the top of the inner joint seam of the U-shaped hardware part. As the telescopic frame 12 shrinks and drives the laser welding head 15 installed by the connecting component to slide down slowly, the entire inner joint seam of the U-shaped hardware part can be laser welded, playing a role in laser welding the inner joint seam of the U-shaped hardware part, ensuring the laser welding efficiency of the special-shaped hardware part. At the same time, through the setting that the sliding frame 14 drives the laser welding head 15 to slide out, it can also adapt to the welding of other parts of special-shaped hardware parts.

[0029] The connection component includes a first servo motor 2, a connecting frame 21, a second servo motor 22 and a first wheel disc 23; the first servo motor 2 is fixedly connected to the outer wall of the telescopic frame 12; the connecting frame 21 is fixedly connected to the output end of the first servo motor 2; the second servo motor 22 is fixedly connected to the outer wall of one end of the connecting frame 21 away from the first servo motor 2; the first wheel disc 23 is fixedly connected to the output end of the second servo motor 22, the first wheel disc 23 is rotatably connected to the inner wall of the connecting frame 21, and the outer wall of the first wheel disc 23 is fixedly connected to the outer wall of the welding frame 13; when laser welding the inner joint of the C-shaped hardware, the connecting frame 21 is fixed to the output end of the first servo motor 2, and when the output end of the first servo motor 2 rotates, it can drive the laser welding head 15 to adjust the vertical angle of its welding. As the output end of the second servo motor 22 drives the first wheel disc 23 to rotate, the vertical angle of the welding frame 13 can be adjusted, so that the laser welding head 15 can fit the inner joint of the C-shaped hardware for welding, improving the welding effect of the inner joint of the C-shaped hardware.

[0030] A sensor 3 is fixedly connected to the top end of the welding frame 13; a plurality of contact points 31 are installed on the inner wall of the sensor 3; a sliding block 32 is slidably connected to the inner wall of the sensor 3 below the contact points 31; a first elastic member 33 is fixedly connected between the inner wall of the sensor 3 and the top end of the sliding block 32; a convex block 34 is fixedly connected to the upper surface of the sliding frame 14 close to the sliding block 32; when the first electric slider drives the laser welding head 15 at the front end of the sliding frame 14 to slide out and fit the inner joint of the C-shaped hardware, the convex block 34 squeezes the plurality of sliding blocks 32 respectively as the sliding frame 14 slides. The convex block 34 squeezes the sliding block 32 to slide upward, and the sliding block 32 simultaneously squeezes the first elastic member 33 to contract and be stressed, triggering the contact points 31 on the sensor 3. After the contact points 31 are triggered, the sensor 3 sends an electrical signal to the main controller, and the main controller adjusts the power of the laser welding machine. Each contact point 31 corresponds to a set welding machine power. The closer the contact point 31 is to the laser welding head 15, the greater the set welding power. As the length of the sliding frame 14 extending out of the welding frame 13 is longer, the power of the laser welding machine is also greater, ensuring the stability of the output power and welding effect of the laser welding machine.

[0031] The bottom ends of the plurality of sliding blocks 32 are arc-shaped; the top end of the convex block 34 is arc-shaped; during the process of the convex block 34 sliding with the sliding frame 14, relying on the arc at the top end of the convex block 34 to fit the arc at the bottom end of the sliding block 32, the convex block 34 can easily squeeze the sliding block 32 to slide upward. The sliding block 32 after sliding upward squeezes the first elastic member 33 to contract and triggers the contact points 31, and the sensor 3 sends an electrical signal to control the output power of the laser welding machine. After the convex block 34 passes over the sliding block 32, the first elastic member 33 squeezes the sliding block 32 to reset by its elastic force, playing a role in automatically adjusting the output power of the laser welding machine.

[0032] As Figure 1 , Figure 4 and Figure 5 As shown in Figure 4 and Figure 5 , a fixed seat 4 is fixedly connected to the top of the welding base 1 and on the side away from the electric turntable 11; a clamping plate 41 is arranged on the top of the fixed seat 4; a first clamping plate 42 is fixedly connected to the outer wall of the bottom of the clamping plate 41; a second clamping plate 43 is slidably connected to the outer wall of the clamping plate 41 and above the first clamping plate 42 through a second electric slider. When laser welding the C-shaped hardware parts, it is necessary to first assemble multiple hardware plates into a C-shape in advance. Place a vertical plate on the clamping plate 41 above the fixed seat 4 and on the upper surface of the first clamping plate 42. As the second electric slider drives the second clamping plate 43 to slide down until the second clamping plate 43 cooperates with the first clamping plate 42 to clamp the vertical plate, and then splice and fix the two horizontal plates to the two ends of the vertical plate, the inner seam of the C-shaped hardware parts can be laser welded, playing a role in assisting the splicing of the accessories of the C-shaped hardware parts.

[0033] Grooves are formed on the opposite surfaces of the first clamping plate 42 and the second clamping plate 43; an extrusion block 5 is slidably connected to the grooves; a second elastic member 51 is fixedly connected to the outer wall of the extrusion block 5. When splicing the accessories of the C-shaped hardware parts, place the vertical plate in the groove of the first clamping plate 42, push the vertical plate to squeeze the two extrusion blocks 5 on the first clamping plate 42 and the second clamping plate 43 to slide, and the two second elastic members 51 elastically contract. The second clamping plate 43 slides down to make the vertical plate snap into its groove. After releasing the push on the vertical plate, the two second elastic members 51 elastically reset to squeeze the extrusion block 5 to slide, and the two extrusion blocks 5 respectively cooperate with the inner walls of the first clamping plate 42 and the second clamping plate 43 to clamp the vertical plate, facilitating the splicing and welding of the accessories of the C-shaped hardware parts.

[0034] A turntable seat 6 is fixedly connected to the end of the fixed seat 4; a third servo motor 61 is fixedly connected to the outer wall of the turntable seat 6; the output end of the third servo motor 61 is fixedly connected to a second wheel disc 62, and the second wheel disc 62 is rotatably connected to the inner wall of the turntable seat 6, and the outer wall of the second wheel disc 62 is fixedly connected to the outer wall of the clamping plate 41. When laser welding the spliced C-shaped hardware part accessories, the spliced angle is difficult to cooperate with the laser welding head 15 for laser welding. Supported by the turntable seat 6 fixed to the end of the fixed seat 4, as the output end of the third servo motor 61 drives the second wheel disc 62 to rotate, the second wheel disc 62 synchronously drives the C-shaped hardware part accessories clamped on the clamping plate 41 to tilt upward, so that the inner seam of the C-shaped hardware part accessories can be easily laser welded by the laser welding head 15, playing a role in assisting the angle adjustment for facilitating the welding of the inner seam.

[0035] On both sides of the clamping plate 41, there is an adsorption frame 7 connected by relative sliding through a third electric slider; one end of the adsorption frame 7 away from the clamping plate 41 is fixedly connected with an adsorption disc 71; a vacuum pump is arranged inside the second disc 62; the output end of the vacuum pump is fixedly connected with a connecting pipe 72, and the connecting pipe 72 is communicated with the adsorption disc 71 through the adsorption frame 7; when splicing the two cross plates of the C-shaped hardware fitting, first fix the vertical plate between the first clamping plate 42 and the second clamping plate 43, and then place the two cross plates at the adsorption disc 71 respectively. The vacuum pump is communicated to the two adsorption discs 71 through the two connecting pipes 72 and the two adsorption frames 7. The vacuum pump works to vacuum suck the two cross plates from the two adsorption discs 71. As the two third electric sliders drive the two adsorption frames 7 to slide on the clamping plate 41 respectively, the two adsorbed cross plates are correspondingly close to both sides of the vertical plate for splicing, playing a role in adsorbing and splicing the two cross plates of the C-shaped hardware fitting.

[0036] On the outer walls of both sides of the first clamping plate 42, there are support seats 8 fixedly connected; the support seats 8 are located below the adsorption disc 71; when splicing the fittings of the C-shaped hardware, use the two support seats 8 to be fixed on both sides of the first clamping plate 42 respectively. The two support seats 8 cooperate with the first clamping plate 42 to support the bottom of the spliced C-shaped hardware fitting, improving the stability of the C-shaped hardware welding.

[0037] The cross-sectional shapes of the two support seats 8 are L-shaped; there are corner grooves 81 on the two support seats 8; when the fittings of the C-shaped hardware are spliced on the two support seats 8, the inner joints of the vertical plate and the two cross plates are easily blocked by the support seats 8, and it is easy to weld the support seats 8 and the inner joints together during the welding process. By opening the corner grooves 81 on the support seats 8 directly below the inner joints, it can be avoided that the support seats 8 are welded to the C-shaped hardware during laser welding. Using the L-shaped support seats 8, it can stably support the laser welding of the vertical plate and the two cross plates spliced together.

[0038] Working process: When laser welding the U-shaped special-shaped hardware parts, first, the three hardware plates of the U-shaped hardware parts are assembled into a U-shape on the welding machine base 1, and the assembled hardware plates are fixed and limited. Subsequently, the output end of the electric turntable 11 drives the telescopic frame 12 to rotate. The telescopic frame 12 can telescopically move up and down at the output end of the electric turntable 11, so that the laser welding head 15 installed on the connecting component can approach the inner joint formed by the hardware plates. Since the inner joint of the U-shaped hardware part is relatively deep, at this time, the first electric slider drives the sliding frame 14 to slide out on the inner wall of the welding frame 13, adjusting the distance between the laser welding head 15 and the inner joint, so that the laser welding head 15 can be attached to the inner joint of the U-shaped part for welding. The laser welding head 15 starts welding from the top of the inner joint of the U-shaped hardware part. As the telescopic frame 12 retracts, it drives the laser welding head 15 installed on the connecting component to slowly slide down, enabling laser welding of the entire inner joint of the U-shaped hardware part, playing a role in laser welding the inner joint of the U-shaped hardware part, ensuring the laser welding efficiency of the special-shaped hardware part. At the same time, through the setting of driving the laser welding head 15 to slide out by the sliding frame 14, it can also adapt to welding other parts of the special-shaped hardware parts; When laser welding the inner joint of the U-shaped hardware part, the connecting frame 21 is fixed to the output end of the first servo motor 2. When the output end of the first servo motor 2 rotates, it can drive the laser welding head 15 to adjust its welding up and down angles. As the output end of the second servo motor 22 drives the first wheel disc 23 to rotate, the up and down angles of the welding frame 13 can be adjusted, so that the laser welding head 15 can be attached to the inner joint of the U-shaped hardware part for welding, improving the welding effect of the inner joint of the U-shaped hardware part;

[0039] When the first electric slider drives the laser welding head 15 at the front end of the sliding frame 14 to slide out and attach to the inner joint of the U-shaped hardware part, the convex blocks 34 respectively squeeze a plurality of sliding blocks 32 as the sliding frame 14 slides. The convex blocks 34 squeeze the sliding blocks 32 to slide upward. The sliding blocks 32 simultaneously squeeze the first elastic member 33 to contract and apply force, triggering the contacts 31 on the sensor 3. After the contacts 31 are triggered, the sensor 3 sends an electrical signal to the total controller, and the total controller adjusts the power of the laser welding machine. Each contact 31 corresponds to a set welding machine power. The contact 31 closer to the laser welding head 15 has a larger set welding power. As the length of the sliding frame 14 extending out of the welding frame 13 becomes longer, the power of the laser welding machine also becomes larger, ensuring the stability of the output power and welding effect of the laser welding machine; During the process of the convex blocks 34 sliding with the sliding frame 14, relying on the arc at the top of the convex blocks 34 to fit the arc at the bottom of the sliding blocks 32, the convex blocks 34 can easily squeeze the sliding blocks 32 to slide upward. After the sliding blocks 32 slide upward, they squeeze the first elastic member 33 to contract and trigger the contacts 31, and the sensor 3 sends an electrical signal to control the output power of the laser welding machine. After the convex blocks 34 pass over the sliding blocks 32, the first elastic member 33 relies on its elastic force to squeeze the sliding blocks 32 to reset, playing a role in automatically adjusting the output power of the laser welding machine;

[0040] When laser welding the U-shaped hardware, it is necessary to first assemble multiple hardware plates into a U-shape. Place a vertical plate on the clamping plate 41 above the fixed seat 4 in advance and on the upper surface of the first clamping plate 42. As the second electric slider drives the second clamping plate 43 to slide down until the second clamping plate 43 cooperates with the first clamping plate 42 to clamp the vertical plate. Then, splice and fix the two horizontal plates to the two ends of the vertical plate, and then laser weld the inner joints of the U-shaped hardware, which plays a role in assisting the splicing of the accessories of the U-shaped hardware. When splicing the accessories of the U-shaped hardware, place the vertical plate in the groove of the first clamping plate 42, push the vertical plate to squeeze the two extrusion blocks 5 on the first clamping plate 42 and the second clamping plate 43 to slide. The two second elastic members 51 elastically contract. The second clamping plate 43 slides down so that the vertical plate is stuck in its groove. After releasing the push of the vertical plate, the two second elastic members 51 return to their original positions elastically and squeeze the extrusion blocks 5 to slide. The two extrusion blocks 5 respectively cooperate with the inner walls of the first clamping plate 42 and the second clamping plate 43 to clamp the vertical plate, which is convenient for splicing and welding the accessories of the U-shaped hardware.

[0041] When laser welding the assembled U-shaped hardware accessories, the spliced angle is difficult to cooperate with the laser welding head 15 for laser welding. Use the turntable seat 6 to be fixed at the end of the fixed seat 4 for support. As the output end of the third servo motor 61 drives the second wheel disc 62 to rotate, the second wheel disc 62 synchronously drives the U-shaped hardware accessories clamped on the clamping plate 41 to tilt upward, so that the inner joint of the U-shaped hardware accessories can be easily laser welded by the laser welding head 15, which plays a role in assisting the angle adjustment for welding the inner joint. When splicing the two horizontal plates of the U-shaped hardware accessories, first fix the vertical plate between the first clamping plate 42 and the second clamping plate 43. Then place the two horizontal plates at the suction discs 71 respectively. The vacuum pump is connected to the two suction discs 71 through two connecting pipes 72 and two suction brackets 7. The vacuum pump works to vacuum suction the two horizontal plates from the two suction discs 71. As the two third electric sliders drive the two suction brackets 7 to slide on the clamping plate 41 respectively, the two adsorbed horizontal plates are correspondingly close to the two sides of the vertical plate for splicing, which plays a role in adsorbing and splicing the two horizontal plates of the U-shaped hardware accessories. When splicing the accessories of the U-shaped hardware, use two support seats 8 to be fixed on both sides of the first clamping plate 42 respectively. The two support seats 8 and the first clamping plate 42 can support the bottom of the spliced U-shaped hardware accessories, improving the stability of the U-shaped hardware welding. When the accessories of the U-shaped hardware are spliced on the two support seats 8, the inner joints of the vertical plate and the two horizontal plates are easily blocked by the support seats 8, and it is easy to weld the support seats 8 to the inner joints during the welding process. By opening a corner groove 81 on the support seat 8 directly below the inner joint, it can avoid welding the support seat 8 to the U-shaped hardware during laser welding. Using the L-shaped support seat 8 can stably support the splicing and laser welding of the vertical plate and the two horizontal plates.
