Description

Technical Field

[0001] The invention belongs to the technical field of switch cabinet production, and particularly relates to a welding device for switch cabinet production. Background Art

[0002] Switchgear is a common type of power distribution equipment in power systems. Its primary function is to open and close, control, and protect electrical equipment during power generation, transmission, distribution, and conversion. Switchgear production requires the assembly and welding of multiple metal plates.

[0003] In the prior art, the welding of switch cabinets is generally performed by an operator holding a welding gun to bring two metal plates together and weld them. In this process, single-person operation is relatively difficult, and generally two operators are required to cooperate with each other, which has low production efficiency. The operator is required to weld one side of the steel plate before welding the other side. In addition, during manual welding, due to unstable manual support, the two metal plates are prone to misalignment and offset, which causes great trouble for the subsequent assembly and welding of the metal plates. In addition, for some switches with special protection requirements, the thickness of the top plate and the side plates may be different during design, which is relatively inconvenient when supporting and fixing the metal plates. Summary of the Invention

[0004] In view of the above situation, in order to overcome the defects of the prior art, the present invention provides a welding device for switch cabinet production, which can firmly clamp multiple metal plates while automatically aligning the anti-deflection welding mechanism with the gap between the two metal plates. In addition, for switch cabinets of different sizes and design requirements, the plates can be automatically supported and positioned from the inside and outside at the same time during welding to avoid misalignment.

[0019] The beneficial effects achieved by the present invention using the above structure are as follows:

[0020] 1. Through two sets of symmetrically arranged transverse clamping and sliding mechanisms and two sets of symmetrically arranged longitudinal clamping and sliding mechanisms, the four metal plates of the switch cabinet can be clamped and fixed at the same time, which facilitates the rapid splicing and assembly of the four metal plates into a rectangular cabinet. The transverse clamping and sliding mechanisms and the longitudinal clamping and sliding mechanisms are moved and adjusted respectively to facilitate clamping and welding of switch cabinets of different sizes.

[0021] 2. When the horizontal clamping sliding mechanism and the vertical clamping sliding mechanism are moved and adjusted, the diagonal slide is driven to move by the horizontal guide rod and the vertical guide rod respectively, so that the diagonal slide is always located at the cabinet corner of the cabinet. The diagonal slide drives the L-shaped self-separating diagonal positioning component to adjust, so that the L-shaped self-separating diagonal positioning component is pressed against the outer sides of the cabinet corner to clamp and correct the weld of the cabinet corner.

[0022] 3. A follow-up inner support mechanism is provided. When the transverse clamping sliding mechanism and the longitudinal clamping sliding mechanism are clamping, the sliding splint drives the inner support triangular column to slide through the transverse follow-up multi-stage telescopic rod and the longitudinal follow-up multi-stage telescopic rod, and the inner support triangular column drives the transverse follow-up multi-stage telescopic rod to extend and retract. When the sliding splints on both sides of the inner support triangular column are in contact with the side walls of the metal plate, the two side walls of the inner support triangular column are also aligned with the side walls of the sliding splints on both sides thereof, supporting and fixing the joint of the two metal plates from the inside, clamping and correcting the welds at the cabinet corners, avoiding uneven welding gap widths and bending of the workpiece edges, thereby ensuring welding quality.

[0023] 4. Connect the anti-deflection welding mechanism to the diagonal slide together, so that when the diagonal slide is automatically adjusted, the anti-deflection welding mechanism will also move accordingly, ensuring that the end of the anti-deflection welding mechanism is always aligned with the cabinet corner, making it convenient to weld the splicing gap.

[0024] 5. A V-shaped bracket is set between the anti-deflection welding mechanism and the two side walls of the self-separating diagonal positioning assembly. When clamping, the oblique edges of the horizontal positioning plate and the longitudinal positioning plate remain in contact. At this time, the horizontal positioning plate and the longitudinal positioning plate are convenient for automatic positioning and adjustment of the two connected plates. When the adjustment is completed and welding is required, the electric push rod contracts and drives the anti-deflection welding mechanism to approach the diagonal slide seat along the diagonal line. The anti-deflection welding mechanism pushes the horizontal positioning plate to slide along the horizontal guide rod away from the longitudinal positioning plate through the first hinge rod. The anti-deflection welding mechanism pushes the longitudinal positioning plate to slide along the longitudinal guide rod away from the longitudinal positioning plate through the second hinge rod, thereby ensuring that the metal plates are supported and fixed while facilitating the exposure of the butt joint gap between the two plates for welding.

[0025] 6. A line laser is set up to detect whether the joints of two metal plates are aligned to avoid offset and misalignment. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] When in use, first place the four metal plates that make up the switch cabinet on the two sets of transverse clamping and sliding mechanisms 2 and the two sets of longitudinal clamping and sliding mechanisms 3 in turn and clamp them firmly. In the initial state, the electric push rod 13 is in an extended state. At this time, the anti-deflection welding mechanism 14 pulls the oblique edges of the transverse positioning plate 15 and the longitudinal positioning plate 16 through the hinge rod 1 17 and the hinge rod 2 18 to keep them in contact. At this time, the transverse positioning plate 15 and the longitudinal positioning plate 16 are convenient for positioning and adjusting the two connected plates. When clamping, place the metal plate between the fixed clamping plate 33 and the sliding clamping plate 34, and ensure that the bottom edge of the metal plate is in contact with the upper wall of the diagonal slide 8. Then start the transverse clamping and sliding mechanism 2 or the longitudinal clamping and sliding mechanism 3. If the metal plate is placed on the transverse clamping and sliding mechanism 2, The longitudinal drive assembly 53 is started, and vice versa, the transverse drive assembly 52 is started. When the metal plate is placed on the transverse clamping sliding mechanism 2, the longitudinal drive motor 60 is started, and the longitudinal drive motor 60 drives the longitudinal transmission gear ring 59 to rotate through the longitudinal drive gear 61, and the longitudinal transmission gear ring 59 drives the drive shaft 55 to rotate, and the drive shaft 55 drives the longitudinal drive bevel gear 51 to rotate, and the longitudinal drive bevel gear 51 drives the two longitudinal bevel gears 48 to rotate, and the two longitudinal bevel gears 48 drive the sliding screws 43 of the two sets of longitudinal clamping sliding mechanisms 3 to rotate synchronously, and the sliding screws 43 drive the sliding thread slide 44 to slide along the sliding groove 45, and the sliding thread slide 44 drives the clamping device 30 to move, and the sliding screws 43 of the two sets of longitudinal clamping sliding mechanisms 3 rotate synchronously. The clamping devices 30 of the two sets of longitudinal clamping sliding mechanisms 3 are driven to move synchronously toward each other, thereby adjusting the distance between the clamping bases 31 of the two sets of longitudinal clamping sliding mechanisms 3, the clamping base 31 drives the longitudinal guide rod 7 to move, the longitudinal guide rod 7 drives the diagonal slide 8 to slide along the transverse guide rod 6, and the diagonal slide 8 drives the L-shaped self-separating diagonal positioning component 10 to approach the side of the metal plate clamped by the transverse clamping sliding mechanism 2. When both sides of the metal plate clamped by the transverse clamping sliding mechanism 2 are in contact with the side wall of the self-separating diagonal positioning component 10, the longitudinal drive motor 60 is turned off, and then the clamping motor 42 of the transverse clamping sliding mechanism 2 is started, the clamping motor 42 drives the clamping screw 40 to rotate, and the clamping screw 40 drives the clamping slide 39 along the clamping The slide groove 41 slides, so that the sliding clamping plate 34 moves close to the fixed clamping plate 33, clamping the metal plate between the sliding clamping plate 34 and the fixed clamping plate 33, so as to clamp and fix switch cabinet plates of different thicknesses. When the sliding clamping plate 34 of the horizontal clamping sliding mechanism 2 moves, the horizontal follower multi-stage telescopic rod 37 drives the inner supporting triangular column 36 to slide along the direction of the longitudinal guide rod 7, and the inner supporting triangular column 36 drives the longitudinal follower multi-stage telescopic rod 38 to retract. When the metal plate is placed on the longitudinal clamping sliding mechanism 3, the horizontal drive motor 57 is started, and the horizontal drive motor 57 drives the horizontal transmission gear ring 56 to rotate through the horizontal drive gear 58. The horizontal transmission gear ring 56 drives the drive sleeve 54 to rotate, and the drive sleeve 54 drives the horizontal drive bevel gear 50 to rotate.The transverse driving bevel gear 50 drives the two transverse bevel gears 47 to rotate, and the two transverse bevel gears 47 drive the sliding screws 43 of the two sets of transverse clamping sliding mechanisms 2 to rotate synchronously, and the sliding screws 43 of the two sets of transverse clamping sliding mechanisms 2 rotate synchronously to drive the clamping devices 30 of the two sets of transverse clamping sliding mechanisms 2 to move toward each other synchronously, thereby adjusting the distance between the clamping bases 31 of the two sets of transverse clamping sliding mechanisms 2, and the clamping base 31 drives the transverse guide rod 6 to move, and the transverse guide rod 6 drives the diagonal slide 8 to slide along the longitudinal guide rod 7, and the diagonal slide 8 drives the L-shaped self-separating diagonal positioning assembly 10 to approach the side of the metal plate clamped by the longitudinal clamping sliding mechanism 3. When both sides of the metal plate clamped by the longitudinal clamping sliding mechanism 3 are aligned with the self-separating diagonal positioning assembly 10 When the side walls are fitted together, the transverse drive motor 57 is turned off, and then the clamping motor 42 of the longitudinal clamping sliding mechanism 3 is started to drive the sliding clamping plate 34 to move and clamp and fix the metal plate on the longitudinal clamping sliding mechanism 3. When the sliding clamping plate 34 of the longitudinal clamping sliding mechanism 3 moves, the sliding clamping plate 34 drives the inner supporting triangular column 36 to slide along the direction of the transverse guide rod 6 through the longitudinal follow-up multi-stage telescopic rod 38, and the inner supporting triangular column 36 drives the transverse follow-up multi-stage telescopic rod 37 to extend and retract. The longitudinal follow-up multi-stage telescopic rod 38 and the transverse follow-up multi-stage telescopic rod 37 ensure that the two side walls of the inner supporting triangular column 36 are always aligned with the side walls of the sliding clamping plate 34 on both sides thereof, so that when the sliding clamping plates 34 on both sides of the inner supporting triangular column 36 are tightly fitted with the two metal plates. , the two side walls of the inner supporting triangular column 36 are respectively fitted with the two metal plates, and the above operation is repeated to fix the four metal plates in turn on the two sets of horizontal clamping sliding mechanisms 2 and the two sets of longitudinal clamping sliding mechanisms 3. After the clamping and fixing are completed, the side edges of the four metal plates are spliced ​​together, and the horizontal clamping sliding mechanism 2 and the longitudinal clamping sliding mechanism 3 are moved and adjusted so as to clamp and weld switch cabinets of different sizes. The diagonal slide 8 can be driven by the horizontal guide rod 6 and the longitudinal guide rod 7 to automatically adjust to the corner of the switch cabinet. When the diagonal slide 8 moves, it drives the self-separating diagonal positioning assembly 10 and the anti-bias welding mechanism 14 to move synchronously. When the sides of the four metal plates are spliced ​​together, the diagonal slide 8 drives the L-shaped self-separating diagonal positioning assembly 10 to align with the outer corner of the cabinet. The two sides are pressed tightly, and the two side walls of the inner supporting triangular column 36 are pressed against the inner two sides of the cabinet corner from the inside to clamp and correct the gap of the cabinet corner to avoid uneven welding gap width and bending of the workpiece edge to ensure welding quality. Then start the line laser 28, which emits laser along the diagonal line of the diagonal slide 8. If the gap is not offset or misaligned, the laser line coincides with the splicing gap of the two metal plates. The line laser 28 is used to easily detect whether the cabinet corner gap is corrected in place. If it is not corrected in place, the sliding assembly 29 of the horizontal clamping sliding mechanism 2 and the sliding assembly 29 of the longitudinal clamping sliding mechanism 3 are used to fine-tune again so that the gap is aligned with the laser emitted by the line laser 28. When the adjustment is completed and welding is required,The electric push rod 13 is controlled to retract and drive the anti-deflection welding mechanism 14 to approach the gap. The electric push rod 13 drives the anti-deflection welding mechanism 14 to approach the diagonal slide 8 along the diagonal line. The anti-deflection welding mechanism 14 pushes the horizontal positioning plate 15 along the horizontal guide rod 6 to slide away from the longitudinal positioning plate 16 through the hinge rod 1 17. The anti-deflection welding mechanism 14 pushes the longitudinal positioning plate 16 along the longitudinal guide rod 7 to slide away from the longitudinal positioning plate 16 through the hinge rod 2 18, thereby ensuring that the metal plates are supported and fixed while facilitating the exposure of the gap between the two metal plates. When the end of the welding gun body 27 is fitted into the splicing gap of the two metal plates, the electric push rod 13 is controlled to stop retracting, and then the lifting motor 25 and the welding gun body 27 are started. The lifting motor 25 drives the lifting screw The rod 23 rotates, and the lifting screw 23 drives the lifting slide 24 to move vertically along the lifting screw 23 and the guide rod 22. The lifting slide 24 drives the welding gun body 27 to move vertically, thereby welding the splicing gap between the two metal plates. The four sets of anti-deflection welding mechanisms 14 can be controlled to weld simultaneously, improving work efficiency, so that the four metal plates are quickly welded to form a preliminary switch cabinet. After welding is completed, the lifting motor 25 and the welding gun body 27 are controlled to stop working, and then the electric push rod 13 is controlled to extend and reset. The electric push rod 13 drives the anti-deflection welding mechanism 14 away from the formed cabinet. Then the sliding clamps 34 of the horizontal clamping sliding mechanism 2 and the longitudinal clamping sliding mechanism 3 are controlled to slide away from the metal plates, and the pre-formed cabinet can be removed.
