Description

Technical Field

[0001] This utility model relates to the field of cabinet manufacturing, and in particular to a welding equipment for reinforcing ribs on the top plate of a cabinet. Background Technology

[0002] Metal cabinets, also known as steel cabinets, are generally categorized by function, including filing cabinets, mobile shelving, blueprint cabinets, lockers, storage cabinets, key cabinets, shoe cabinets, and employee lockers. They are made of cold-rolled steel sheets (commonly known as sheet metal), and are characterized by being lighter than wooden cabinets, easier to move, and fireproof, moisture-proof, insect-proof, moth-proof, and corrosion-resistant. Because the sheet metal used in the cabinet is relatively thin, the overall weight is relatively light. However, the top panel of the thinner sheet metal cabinet has weaker structural strength, necessitating the welding of reinforcing ribs at the bottom. To improve the overall support strength, spot welding machines are generally used for welding such thin plates. However, during spot welding, the top plate needs to be held and the welding head needs to be aligned with the position where the reinforcing rib needs to be welded. Since the top plate is thin, there may be burrs at the edges and corners from the shearing process. Therefore, constantly moving the top plate being welded may cause hand injuries, which is very inconvenient. Furthermore, since the top plate does not have relative limits, the reinforcing rib may move inside the top plate when moving the welding position, resulting in defective products in the welding of the reinforcing rib. Utility Model Content

[0003] The purpose of this utility model is to provide a welding device for reinforcing ribs on the top plate of a cabinet in order to solve the above-mentioned problems.

[0004] This utility model achieves the above objectives through the following technical solutions:

[0005] A cabinet top plate reinforcing rib welding equipment includes a welding mechanism for connecting the top plate blank and the reinforcing rib, and a clamping mechanism for fixing the top plate blank and the reinforcing rib.

[0006] The clamping mechanism includes a first movable base, on the top of which are slidably connected two L-shaped sliding frames, which are arranged in a rotationally symmetrical manner. Each sliding frame has a fixed plate and a clamping seat at the end away from the first movable base. The fixed plate is fixed to the top of the sliding frame, and the lower end of the clamping seat is slidably connected inside the sliding frame. The clamping seat is provided with a first spring for pulling it closer to the fixed plate at the position inside the sliding frame. The two sliding frames have slots at the position where they fit together, and a second spring for driving the ends of the two sliding frames to move closer to each other is fixed in the slots of the two sliding frames. A pushing mechanism is provided on the rear side of the first movable base for pushing it forward.

[0007] Preferably, the welding mechanism includes a welding host, a second movable seat is provided on the front side of the welding host, a movable welding head is fixed on the front side of the second movable seat, a welding cylinder for driving it to move up and down is fixed on the upper side of the second movable seat, a welding head is fixed on the lower side of the movable welding head, and a guide seat is provided on the lower side of the first movable seat.

[0008] Preferably, the rear end of the second movable seat is fixed with a push arm for pushing the guide seat downward, and the front side of the welding host is provided with two opposing welding brackets.

[0009] Preferably, the bottom of the guide seat is fixed with four vertically arranged guide columns, and a reset spring is provided between the four guide columns to push the push arm to move upward. The welding bracket is provided with sliding holes for the four guide columns to slide.

[0010] Preferably, the sliding frame has a groove at a position away from the first movable seat for allowing the clamping seat to slide back and forth, and the first spring is located inside the groove.

[0011] Preferably, the pushing mechanism includes a lead screw, one end of which is threadedly connected to a push seat, and the other end of the lead screw is provided with a support plate fixed to one side of the guide seat. A pushing motor is fixedly installed at the input end of the lead screw, and a rotating sleeve is provided at the position of the first moving seat near the push seat.

[0012] The advantages compared with the existing technology are as follows: During spot welding, the push arm pushes the guide seat to move the clamping mechanism, reinforcing ribs and top plate blank downwards. At the same time, the second spring drives the ends of the two sliding frames to move closer to each other, and then the two fixed plates clamp the two sides of the top plate blank. Meanwhile, the two sets of clamping seats and the first spring are used to clamp and fix the diagonal positions of the top plate blank. This makes it convenient to weld multiple positions of the top plate blank. During this process, the entire top plate blank can be pushed forward horizontally, thereby avoiding the occurrence of reinforcing rib displacement. Attached Figure Description

[0028] The present invention will be further described below with reference to the accompanying drawings:

[0029] like Figures 1-11 As shown, a cabinet top plate reinforcing rib welding equipment includes a welding mechanism 2 for connecting the top plate blank 4 and the reinforcing rib 5, and a clamping mechanism 1 for fixing the top plate blank 4 and the reinforcing rib 5. The clamping mechanism 1 is provided with a pushing mechanism 3 on the rear side for pushing the top plate blank 4 and the reinforcing rib 5 forward.

[0030] In this embodiment: the clamping mechanism 1 includes a first movable base 15, and two L-shaped sliding frames 11 are slidably connected to the top of the first movable base 15. The two sliding frames 11 are arranged in a rotationally symmetrical manner. Each sliding frame 11 has a fixed plate 12 and a clamping seat 13 at the end away from the first movable base 15. The fixed plate 12 is fixed to the top of the sliding frame 11, and the lower end of the clamping seat 13 is slidably connected to the inside of the sliding frame 11. The clamping seat 13 is provided with a first spring 14 for pulling it closer to the fixed plate 12 at the position where the two sliding frames 11 are in contact with each other. The two sliding frames 11 are fixed with a spring for driving the two sliding frames 11 to move closer to the fixed plate 12. The two sliding frames 11 are positioned close to each other by a second spring 16. A groove is provided on the sliding frame 11 away from the first moving seat 15 to allow the clamping seat 13 to slide back and forth. The first spring 14 is located inside the groove. The second spring 16 drives the two sliding frames 11 to move closer together by one end of the fixed plate 12. At the same time, the first spring 14 on each sliding frame 11 drives the clamping seat 13 to move closer to the top plate blank 4, thereby clamping and fixing the top plate blank 4 to the top of the first moving seat 15 and contacting the bottom of the first moving seat 15. The two sliding frames 11 can be pushed to move along the first moving seat 15 to both sides, thereby adjusting the welding position of the reinforcing rib 5.

[0031] In this embodiment: the welding mechanism 2 includes a welding host 21, a second movable seat 23 is provided on the front side of the welding host 21, a movable welding head 24 is fixed on the front side of the second movable seat 23, a welding cylinder 22 for driving it to move up and down is fixed on the upper side of the second movable seat 23, a welding head 25 is fixed on the lower side of the movable welding head 24, a guide seat 7 is provided on the lower side of the first movable seat 15, a push arm 6 for pushing the guide seat 7 to move downward is fixed at the rear end of the second movable seat 23, two opposing welding brackets are provided on the front side of the welding host 21, and the bottom of the guide seat 7 is fixed There are four vertically arranged guide pillars, and a return spring is provided between the four guide pillars to push the push arm 6 to move upward. The welding bracket is provided with sliding holes for the four guide pillars to slide. The welding cylinder 22 on the front side of the welding host 21 pushes the second moving seat 23 to move downward. The downward movement of the second moving seat 23 drives the moving welding head 24 to abut against the position where the reinforcing rib 5 needs to be welded. At this time, the moving welding head 24 and the fixed welding head 25 are used to spot weld the reinforcing rib 5 and the top plate blank 4, thereby completing the entire welding process between the top plate blank 4 and the reinforcing rib 5.

[0032] In this embodiment: the pushing mechanism 3 includes a lead screw 32, one end of which is threadedly connected to a push seat 33, and the other end of the lead screw 32 is provided with a support plate fixed to one side of the guide seat 7. The input end of the lead screw 32 is fixedly provided with a push motor 31. The first moving seat 15 is provided with a rotating sleeve 34 near the push seat 33. The rotating part of the push motor 31 drives the lead screw 32 to rotate. The rotation of the lead screw 32 drives the push seat 33 to move towards the push motor 31. During this process, the push seat 33 pushes the rotating sleeve 34, thereby causing the first moving seat 15 to move forward step by step.

[0033] Working principle: When in use, the top plate blank 4 to be welded is first placed between the two fixed plates 12 and the two clamping seats 13. At this time, the top plate blank 4 will contact the top of the first moving seat 15. At this time, the second spring 16 inside the two sliding frames 11 will pull the two closer to each other, so that the fixed plates 12 on the two sliding frames 11 clamp and fix the two sides of the top plate blank 4. Then, the first spring 14 drives the clamping seats 13 to move towards the fixed plates 12, and then the two clamping seats 13 clamp and fix the diagonal position of the top plate blank 4.

[0034] Then, the reinforcing rib 5 to be welded is placed on the top plate blank 4. At this time, the two sliding frames 11 can be pushed to move to either side on the first moving seat 15 so that the required position of the reinforcing rib 5 is between the moving welding head 24 and the fixed welding head 25. Then, the welding cylinder 22 pushes the second moving seat 23 to move downward. During this process, the push arm 6 on the rear side of the second moving seat 23 pushes the guide seat 7 to move downward, and the guide column at the bottom of the guide seat 7 will move downward along the sliding hole of the welding bracket. Then, the upper end of the fixed welding head 25 is pressed against the position to be welded on the top plate blank 4. During the downward movement of the second moving seat 23, the moving welding head 24 is also driven to press the reinforcing rib 5 and the top plate blank 4 onto the upper end of the fixed welding head 25. Then, the reinforcing rib 5 and the top plate blank 4 are spot welded and fixed by the moving welding head 24 and the fixed welding head 25.

[0035] After a spot weld is completed, the welding cylinder 22 drives the second moving seat 23 to move the moving welding head 24 upward. At this time, the return spring at the bottom of the guide seat 7 pushes it upward, so that the bottom of the first moving seat 15 exceeds the upper end of the fixed welding head 25. Then, the rotating part of the push motor 31 drives the lead screw 32 to rotate. The rotation of the lead screw 32 drives the push seat 33 to move in the direction of the push motor 31. During this process, the push seat 33 pushes the rotating sleeve 34, and then moves the first moving seat 15 forward to the next welding position. Repeat the above steps to complete the welding process of the reinforcing rib 5 and the top plate blank 4.

[0036] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
