Description

Technical Field

[0001] This invention relates to the field of metal welding technology, and in particular to a metal display case processing and welding device. Background Technology

[0002] For stainless steel or iron metal display case panels with a thickness between 0.6mm and 1.2mm, handheld laser welding machines are generally used when splicing the back panel and side panel. The handheld laser welding machine is based on a handheld laser welding gun. The equipment is compact and flexible, and has the advantages of flexible operation, quick learning, beautiful and strong welds, low heat input, no need for welding wire, and energy saving and environmental protection.

[0003] Because the sheet metal of metal display cases is relatively thin, handheld laser welding guns can be used for spot welding or short-segment welding, taking advantage of the large aspect ratio to ensure connection strength while keeping deformation to a very low level and maintaining the flatness of the display case surface. However, modern display cases often use rounded corner designs with arc welds at the edges. This requires the operator to make curved movements when holding the welding gun, making it difficult to keep the welding gun speed constant. Furthermore, the welding angle of the welding gun needs to be adjusted in real time according to the curve, which makes it easy for heat to accumulate in areas with large weld curvature. At present, it is not possible to use auxiliary tools such as straightedges for arc welds, which increases the difficulty of welding operations and results in low welding efficiency and success rate. Therefore, this invention provides a metal display case processing and welding device to meet the requirements. Summary of the Invention

[0004] The technical problem to be solved by this invention is to provide a metal display case processing and welding device. By setting up a running track mechanism, the shape of the first guide rail and the second guide rail after being arranged and combined can be arbitrarily adjusted according to the installation holes reserved on the welding table. This allows the welding gun to weld straight and arc-shaped welds. The switching of the shape of the first guide rail and the second guide rail does not depend on any adjustment structure. The operator can arbitrarily adjust the shape formed by the splicing of the first guide rail and the second guide rail while installing the first guide rail and the second guide rail on the top of the welding table. The above setting can solve the problem of low welding efficiency and success rate when the operator holds the welding gun and moves it in a curved motion.

[0005] To solve the above-mentioned technical problems, the present invention provides the following technical solution: A metal display cabinet processing and welding device, comprising a welding table and a welding gun, wherein a first guide rail is installed on the top of the welding table, a sliding seat is slidably connected to the top of the first guide rail, a support rod is fixedly connected to the top of the sliding seat, the welding gun is installed at the end of the support rod, a positioning adjustment mechanism, the positioning adjustment mechanism is used for adjusting the relative position between the support rod and the welding gun, the positioning adjustment mechanism is respectively connected with the support rod and the welding gun, an operation guide rail mechanism, the operation guide rail mechanism is used for enabling the sliding seat to slide on the top of the first guide rail in different motion trajectories, and the operation guide rail mechanism is respectively connected with the first guide rail and the sliding seat.

[0006] Optionally, the positioning adjustment mechanism comprises a connector fixedly connected to the outer wall of the end part of the support rod, one end of the connector far away from the support rod is rotatably connected with a first adjustment clamping cylinder, a second adjustment clamping cylinder is slidably connected to the first adjustment clamping cylinder, and the welding gun is inserted and fixed in the second adjustment clamping cylinder.

[0007] Optionally, the connector and the first adjustment clamping cylinder are rotatably connected together through a rotating shaft and locked and fixed by a nut, the second adjustment clamping cylinder is of a T-shaped outline as a whole, and the first adjustment clamping cylinder is sleeved on the outer wall of the bottom of the second adjustment clamping cylinder.

[0008] Optionally, both the top of the second adjustment clamping cylinder and the first adjustment clamping cylinder are of a C-shaped outline, both ends of the top of the second adjustment clamping cylinder are in threaded connection with a first locking knob, and the top of the first adjustment clamping cylinder is in threaded connection with a second locking knob.

[0009] Optionally, a first rack and a second rack are fixedly connected to the outer wall of the welding gun and the outer wall of the bottom of the second adjustment clamping cylinder respectively, a first gear adjustment knob and a second gear adjustment knob are rotatably connected to the outer wall of the top of the second adjustment clamping cylinder and the outer wall of the first adjustment clamping cylinder respectively, each of the first gear adjustment knob and the second gear adjustment knob consists of two parts, a gear and a knob, the gear on the first gear adjustment knob is meshed with the first rack, and the gear on the second gear adjustment knob is meshed with the second rack.

[0010] Optionally, the operation guide rail mechanism comprises rollers fixedly connected to the inner walls on both sides of the sliding seat, both sides of the first guide rail are rotatably connected with second guide rails, the outlines of the first guide rail and the second guide rails are consistent, the sliding seat is of an n-shaped outline, and both the first guide rail and the second guide rails are of a pi-shaped outline.

[0011] Optionally, the rollers are divided into upper and lower groups, and there is a gap between the two groups of rollers. Limiting plates are fixedly connected to the outer walls of both ends of the first guide rail and the second guide rail. The limiting plates are located within the gap between the two groups of rollers. A third locking knob is screwed to one side of the slide, and the third locking knob passes through one side of the slide and is located within the gap between the two groups of rollers.

[0012] Optionally, a rotating plate is rotatably connected to the bottom of both sides of the slide. One end of the rotating plate is rotatably connected to the slide, and the other end is fixedly connected to the second guide rail. There is a gap between the first guide rail and the second guide rail.

[0013] Optionally, a first side plate and a second side plate are fixedly connected to both ends of the first guide rail and both ends of the second guide rail, respectively. The first side plate and the second side plate are both fixedly connected to the top of the welding table by screws, and a clamp is fixedly connected to the top of the second side plate.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects: In the above scheme, by setting up a running track mechanism, the shape of the first and second guide rails after being arranged can be arbitrarily adjusted according to the pre-reserved mounting holes on the welding table. This allows the welding torch to weld straight and arc-shaped welds. The switching of the shape of the first and second guide rails does not depend on any adjustment structure. The operator can arbitrarily adjust the shape formed after the first and second guide rails are spliced ​​together while installing them on the top of the welding table. At the same time, the limiting effect of the first and second guide rails on the slide ensures that the slide can slide on the first and second guide rails with different movement trajectories, improving the convenience and applicability of this welding device.

[0015] By setting up a positioning and adjustment mechanism, workers can not only manually adjust the relative position, height, and angle between the welding torch and the support rod, but also achieve higher controllability, better adjustment precision, and more convenient operation during the adjustment process. This allows the welding torch to be used at a reasonable angle and position before welding the metal display case panels, ensuring that the welding torch is always at a suitable distance and angle from the panel during movement, thereby improving the welding quality. Compared with the current manual holding method, this fixing method not only improves the stability of the welding torch during movement, but also ensures that the welding torch remains relatively stable with respect to the panel even when making curved movements.

[0025] like Figures 1 to 3 As shown, an embodiment of the present invention provides a metal display case processing and welding device, including a welding table 1 and a welding torch 10. A first guide rail 2 is installed on the top of the welding table 1, a slide block 5 is slidably connected to the top of the first guide rail 2, a support rod 6 is fixedly connected to the top of the slide block 5, and the welding torch 10 is installed at the end of the support rod 6.

[0026] In this technical solution, several first guide rails 2 are installed on the top of the welding table 1, and the slide block 5 is slidably set on the top of the first guide rails 2. By arranging the first guide rails 2 on the top of the welding table 1 in different contours, the movement trajectory of the slide block 5 can be adjusted. The welding gun 10 is a handheld laser welding machine. With the help of the support rod 6, the welding gun 10 is installed on the top of the slide block 5. Then the slide block 5 moves along the track formed by the arrangement of the first guide rails 2, so that the welding gun 10 can move according to the track shape of the first guide rails 2. This setting replaces the manual operation of the operator to hold and control the welding gun 10, reduces the difficulty of welding operation, improves the efficiency of welding operation, and ensures the accuracy of welding.

[0027] As one implementation method in this embodiment, such as Figures 1 to 5 As shown, the positioning adjustment mechanism is used to adjust the relative position between the support rod 6 and the welding torch 10. The positioning adjustment mechanism is connected to the support rod 6 and the welding torch 10 respectively. The positioning adjustment mechanism includes a connector 7 fixedly connected to the outer wall of the end of the support rod 6. The end of the connector 7 away from the support rod 6 is rotatably connected to a first adjusting clamp 8. A second adjusting clamp 9 is slidably connected to the first adjusting clamp 8. The welding torch 10 is inserted and fixed inside the second adjusting clamp 9. The connector 7 and the first adjusting clamp 8 are rotatably connected together by a rotating shaft and locked by a nut. The second adjusting clamp 9 has a "T" shaped outline. The first adjusting clamp 8 is sleeved on the bottom outer wall of the second adjusting clamp 9. The top of the second adjusting clamp 9 and the first adjusting clamp 8 have "C" shaped outlines. The top two ends of the second adjusting clamp 9 are screwed with a first locking knob 13, and the top of the first adjusting clamp 8 is screwed with a second locking knob 16.

[0028] As mentioned above, by setting up the slide block 5 and the support rod 6, the welding torch 10 can be manually held and controlled by the operator. Specifically, the welding torch 10 and the support rod 6 are connected by a positioning adjustment mechanism, which mainly consists of three parts: a connector 7, a first adjusting clamp 8, and a second adjusting clamp 9. The connector 7 and the first adjusting clamp 8 are rotatably connected together by a rotating shaft and fixed by a nut. The operator can first loosen the nut at the end of the rotating shaft, then rotate to adjust the relative angle between the connector 7 and the first adjusting clamp 8. Finally, after the angle is adjusted, tightening the nut will complete the fixing effect between the connector 7 and the first adjusting clamp 8. Furthermore, the bottom of the second adjusting clamp 9 is inserted into the first adjusting clamp 8. Since the first adjusting clamp 8 has a "C" shaped outline, and the opening of the "C" shaped outline of the first adjusting clamp 8 is screwed... With the second locking knob 16 connected, the operator can adjust the size of the "C"-shaped opening of the first adjusting clamp 8 by turning the second locking knob 16. After the operator inserts the bottom of the second adjusting clamp 9 into the first adjusting clamp 8 and tightens the second locking knob 16, the second adjusting clamp 9 can be fixed. Similarly, since the top of the second adjusting clamp 9 is "C"-shaped, after the operator inserts the welding torch 10 into the top of the second adjusting clamp 9 and tightens the first locking knob 13 at the "C"-shaped opening of the second adjusting clamp 9, the welding torch 10 can be fixed inside the second adjusting clamp 9. Through the above structure, the efficiency of the structural splicing and installation between the first adjusting clamp 8, the second adjusting clamp 9 and the welding torch 10 can be greatly improved, and the efficiency of the operator assembling the welding torch 10 onto the positioning and adjusting mechanism can be improved.

[0029] In this embodiment, as Figures 1 to 5 As shown, a first rack 11 and a second rack 14 are fixedly connected to the outer wall of the welding torch 10 and the bottom outer wall of the second adjusting clamp 9, respectively. A first gear adjusting knob 12 and a second gear adjusting knob 15 are rotatably connected to the top outer wall of the second adjusting clamp 9 and the outer wall of the first adjusting clamp 8, respectively. Both the first gear adjusting knob 12 and the second gear adjusting knob 15 are composed of two parts: a gear and a knob. The gear on the first gear adjusting knob 12 meshes with the first rack 11, and the gear on the second gear adjusting knob 15 meshes with the second rack 14.

[0030] As described above, the welding torch 10 is inserted into the top of the second adjusting clamp 9 and locked in place by the first locking knob 13 located at the "C"-shaped contour of the second adjusting clamp 9. Furthermore, by installing a first rack 11 on the outer wall of the welding torch 10, and having the rack 11 mesh with the gear on the first gear adjusting knob 12, the operator can adjust the relative position between the welding torch 10 and the second adjusting clamp 9 by turning the first gear adjusting knob 12. After the position is adjusted, tightening the first locking knob 13 locks the second adjusting clamp 9 and the welding torch 10 in place. This position adjustment method not only improves the stability of the second adjusting clamp... The precision and controllability of the position adjustment between the second adjusting clamp 9 and the welding torch 10 are ensured. Furthermore, the meshing effect between the first rack 11 and the first gear adjusting knob 12 further guarantees the firmness and stability of the fit between the second adjusting clamp 9 and the welding torch 10. Similarly, by setting the second rack 14 on the bottom outer wall of the second adjusting clamp 9, the operator can adjust the relative position between the second adjusting clamp 9 and the first adjusting clamp 8 by rotating the second gear adjusting knob 15. Since the operation and working principle of the adjustment between the second adjusting clamp 9 and the welding torch 10 are the same as those of the adjustment between the second adjusting clamp 9 and the first adjusting clamp 8, they will not be described in detail.

[0031] Furthermore, by setting up a positioning adjustment mechanism, workers can not only manually adjust the relative position, height, and angle between the welding torch 10 and the support rod 6, but also achieve higher controllability, better adjustment precision, and more convenient adjustment during the adjustment process. This allows the welding torch 10 to be reasonably adjusted in terms of its angle and position before welding the metal display case panel, ensuring that the welding torch 10 is always at a suitable distance and angle from the panel during its movement, thereby improving the welding quality. Compared with the current manual holding method, this fixing method not only improves the stability of the welding torch 10 during its movement, but also ensures that the welding torch 10 can maintain relative stability with the panel even when it is making curved movements.

[0032] As one implementation method in this embodiment, such as Figures 1 to 8As shown, the operating guide rail mechanism is configured to allow the sliding seat 5 to slide on the top of the first guide rail 2 along different motion trajectories. The operating guide rail mechanism is respectively connected to the first guide rail 2 and the sliding seat 5, and comprises rollers 17 fixedly connected to the inner walls on both sides of the sliding seat 5. Both sides of the first guide rail 2 are rotatably connected with second guide rails 3. The first guide rail 2 and the second guide rails 3 have the same contour, the sliding seat 5 has an "n"-shaped contour, and both the first guide rail 2 and the second guide rails 3 have a "几"-shaped contour. The rollers 17 are divided into an upper group and a lower group, and a spacing exists between the two groups of rollers 17. Limiting plates 19 are fixedly connected to the outer walls of both ends of the first guide rail 2 and the second guide rails 3, and the limiting plates 19 are located in the spacing between the two groups of rollers 17. A third locking knob 18 is screwed to one side of the sliding seat 5, and the third locking knob 18 passes through one side of the sliding seat 5 and is located in the gap between the two groups of rollers 17.

[0033] By providing the operating rail mechanism between the sliding seat 5 and the first guide rail 2, the sliding seat 5 can slide on the tops of the first guide rail 2 and the second guide rails 3. Specifically: since the limiting plates 19 on the outer walls of the first guide rail 2 and the second guide rails 3 are exactly located in the gap between the two groups of rollers 17 on the inner wall of the sliding seat 5, the sliding seat 5 is limited to slide on the tops of the first guide rail 2 and the second guide rails 3 by means of the limiting effect between the rollers 17 and the limiting plates 19. In the actual sliding process, the sliding seat 5 is in contact with and slides relative to the first guide rail 2 and the second guide rails 3 mainly through the rollers 17. The rotation of the rollers 17 reduces the frictional force between the sliding seat 5 and the first guide rail 2 as well as the second guide rails 3, so that the worker can easily push the sliding seat 5 to move. Moreover, the two groups of rollers 17 are respectively located at the top and bottom of the limiting plate 19, so that the rollers 17 and the limiting plate 19 limit each other during the sliding process, improving the stability of the structure.

[0034] Further, since the sliding seat 5 has an "n"-shaped contour and both the first guide rail 2 and the second guide rails 3 have a "几"-shaped contour, the overall contour of the sliding seat 5 is adapted to the contours of the tops of the first guide rail 2 and the second guide rails 3. Such a structural arrangement enables good adaptability between the overall structure of the sliding seat 5 and the first guide rail 2 as well as the second guide rails 3 during the movement process, with a higher fitting degree between the structures, no dislocation and deviation, and ensures the stability of the sliding seat 5 during the movement process.

[0035] Still further, by screwing and fixing the third locking knob 18 on one side of the sliding seat 5, when the sliding seat 5 slides to a proper position, the worker can turn the third locking knob 18 to make the end of the third locking knob 18 abut against the outer side of the limiting plate 19. At this time, the fixing effect on the sliding seat 5 is achieved by means of friction force. Such an arrangement allows the worker to manually lock and fix the sliding seat 5 after it stops sliding, preventing the sliding seat 5 from moving by its own inertia and affecting the judgment of the welding position.

[0036] In this embodiment, as Figures 1 to 8 As shown, rotating plates 20 are rotatably connected to the bottom of both sides of the slide 5. One end of the rotating plate 20 is rotatably connected to the slide 5, and the other end is fixedly connected to the second guide rail 3. There is a gap between the first guide rail 2 and the second guide rail 3. The two ends of the first guide rail 2 and the two ends of the second guide rail 3 are respectively fixedly connected to the first side plate 21 and the second side plate 22. The first side plate 21 and the second side plate 22 are both fixedly connected to the top of the welding table 1 by screws. The top of the second side plate 22 is fixedly connected to the clamp 4.

[0037] In the above structure, two second guide rails 3 are respectively installed on both sides of the first guide rail 2. Since there is a certain gap between the first guide rail 2 and the second guide rail 3, and the two are rotatably connected by the rotating plate 20, the operator can adjust the relative angle between the first guide rail 2 and the second guide rail 3 by rotating the second guide rail 3. It is worth mentioning that the gap between the first guide rail 2 and the second guide rail 3 is fixed. When the first guide rail 2 and the second guide rail 3 are rotated to the maximum extent, the rollers 17 on the inner walls of both sides of the slide 5 can still pass smoothly through the gap between the first guide rail 2 and the second guide rail 3. The slide 5 will not be unable to pass through the rotated first guide rail 2 and the second guide rail 3 due to the excessive gap between the first guide rail 2 and the second guide rail 3.

[0038] Furthermore, a first side plate 21 and a second side plate 22 are respectively installed at both ends of the first guide rail 2 and the second guide rail 3. The end of the first side plate 21 is designed with a chamfered structure that slopes inward. This design is to avoid the plate body of the second guide rail 3 after rotation, so that the plate body of the second guide rail 3 will not collide with the sides of the first side plate 21 during rotation. The top of the second side plate 22 has reserved holes for installing a clamp 4, so that the clamp 4 can be directly fixed to the top of the second side plate 22 by means of bolts and nuts. The clamp 4 is used to clamp and fix the plate. The working principle of the plate to be welded is disclosed as prior art in this application and will not be repeated here. In addition, bolt fixing holes are reserved on the first side plate 21 and the second side plate 22. These holes correspond to the holes reserved on the top of the welding table 1. Therefore, the workers can fix the first side plate 21 and the second side plate 22 to the top of the welding table 1 with bolts and nuts according to the reserved holes on the welding table 1. At the same time, the shape of the first guide rail 2 and the second guide rail 3 spliced ​​together can be adjusted according to the arrangement of the reserved holes on the top of the welding table 1.

[0039] Furthermore, by utilizing the rotational effect between the first guide rail 2 and the second guide rail 3, the first guide rail 2 and the second guide rail 3 can be arranged and combined into different shapes on the top of the welding table 1. Shape 1: The first guide rail 2 and the second guide rail 3 are in a relatively parallel state. At this time, several first guide rails 2 and second guide rails 3 are spliced ​​together on the top of the welding table 1 to form a straight outline. During the sliding process of the slide block 5 on the top of the first guide rail 2 and the second guide rail 3, its movement trajectory is a straight line. At this time, the welding gun 10 can perform welding treatment on the straight weld. Shape 2: The operator rotates and adjusts the relative position between the first guide rail 2 and the second guide rail 3, and adjusts the overall outline after several first guide rails 2 and the second guide rail 3 are spliced ​​together according to the reserved mounting holes on the welding table 1, so that the first guide rail 2 and the second guide rail 3 are spliced ​​together to form an arc-shaped outline. At this time, the movement trajectory of the slide block 5 is arc-shaped, and the welding gun 10 can perform welding treatment on the weld of the plate after the rounded corner.

[0040] Optionally, the outline formed by the arrangement of the first guide rail 2 and the second guide rail 3 in this application includes, but is not limited to, the above-mentioned shape one and shape two. Workers can open corresponding holes on the welding table 1 according to product requirements, so that the first guide rail 2 and the second guide rail 3 can be arranged to form different shapes.

[0041] With the above-mentioned structure, the shape of the first guide rail 2 and the second guide rail 3 after being arranged can be arbitrarily adjusted according to the pre-reserved mounting holes on the welding table 1, so that the welding torch 10 can weld straight and arc-shaped welds. The switching of the shape of the first guide rail 2 and the second guide rail 3 does not depend on any adjustment structure. The operator can arbitrarily adjust the shape formed after the first guide rail 2 and the second guide rail 3 are spliced ​​together during the process of installing the first guide rail 2 and the second guide rail 3 on the top of the welding table 1. At the same time, with the limiting effect of the first guide rail 2 and the second guide rail 3 on the slide block 5, it is ensured that the slide block 5 can slide on the first guide rail 2 and the second guide rail 3 with different movement trajectories, which improves the convenience and applicability of this welding device.

[0042] The working principle of the technical solution provided by this invention is as follows: In use, the staff first fixes several first guide rails 2 and second guide rails 3 on the top of the welding table 1 according to the shape of the weld seam of the metal display case plate, so that the outline formed by the arrangement of several first guide rails 2 and second guide rails 3 is consistent with the outline of the weld seam of the plate. After the first guide rails 2 and second guide rails 3 are fixed on the top of the welding table 1, the staff slides the slide block 5 to the end of the track formed by the combination of the first guide rails 2 and second guide rails 3, and then tightens the third locking knob 18 to fix the slide block 5 on the track.

[0043] After the slide block 5 is fixed, the plate to be welded is fixed on the top of the welding table 1 with the help of the clamp 4. Then, the worker inserts the welding torch 10 into the "C"-shaped contour at the top of the second adjusting clamp 9. After insertion, the angle and height of the welding torch 10 are adjusted according to the position of the weld. The specific adjustment operation is as follows: the worker turns the first gear adjusting knob 12 to make the gear on the first gear adjusting knob 12 drive the first rack 11 on the welding torch 10 to move, thereby adjusting the relative position between the welding torch 10 and the second adjusting clamp 9. After the position is adjusted, the second adjusting clamp 9 and the welding torch 10 can be locked and fixed by tightening the first locking knob 13. Similarly, the worker turns the second gear... Adjusting knob 15 adjusts the relative position between the second adjusting clamp 9 and the first adjusting clamp 8. Since the operation and working principle of adjusting the second adjusting clamp 9 and the welding torch 10 are the same as those of adjusting the second adjusting clamp 9 and the first adjusting clamp 8, they will not be described in detail. Finally, the operator first loosens the nut at the end of the shaft between the connector 7 and the first adjusting clamp 8, and then rotates to adjust the relative angle between the connector 7 and the first adjusting clamp 8. After the angle is adjusted, tightening the nut completes the fixing effect between the connector 7 and the first adjusting clamp 8. With the help of the upper adjustment structure, the welding torch 10 is at a suitable angle and height with the weld seam so that subsequent welding operations can be carried out.

[0044] After the position of the welding torch 10 is determined, the staff starts the welding torch 10 and manually pushes it, so that the slide 5 moves above the track formed by the arrangement of the first guide rail 2 and the second guide rail 3. At this time, the welding torch 10 will automatically move along the weld seam according to the shape of the track, thereby completing the welding operation on the plate.

[0045] This invention encompasses any substitutions, modifications, equivalent methods, and solutions made within the spirit and scope of this invention. To provide the public with a thorough understanding of this invention, specific details are described in detail in the following preferred embodiments; however, those skilled in the art will fully understand the invention even without these details. Furthermore, to avoid unnecessary misunderstanding of the essence of this invention, well-known methods, processes, procedures, components, and circuits are not described in detail.
