Description

Technical Field

[0001] This utility model relates to the technical field of barbecue grill frame welding equipment, specifically an automatic welding machine. Background Technology

[0002] A barbecue grill is a type of grilling equipment that can be used to grill lamb skewers, meat, vegetables, and other grilled foods. The essence of a barbecue grill is to heat and cook food using a heat source. In a narrow sense, a barbecue grill refers to a common barbecue grill, while in a broader sense, it can encompass different forms such as teppanyaki.

[0003] A barbecue grill mainly consists of the grill body, grill frame, and support corners. The grill frame is used to place the food for grilling, separating the food from the charcoal fire. The grill frame is mostly grid-like and is made by welding multiple steel bars together. An automatic welding machine is required during the manufacturing process.

[0004] However, the existing barbecue grill frame is grid-shaped, and a lot of time is required to position the steel bars during welding, which reduces the welding efficiency of the barbecue grill frame; therefore, it does not meet the current needs, so we propose an automatic welding machine. Utility Model Content

[0005] The purpose of this invention is to provide an automatic welding machine to solve the problems mentioned in the background art, such as the fact that when the barbecue grill frame is grid-shaped, a lot of time needs to be spent positioning the steel bars during welding, which leads to a decrease in the welding efficiency of the barbecue grill frame.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an automatic butt welding machine, including a fixed base, the upper surface of which is provided with a square groove, and multiple parallel lifting bars are slidably installed on the inner side of the square groove. Multiple equally spaced lifting plates are fixed on both sides of the lifting bars, and electric lifting telescopic rods are fixed at both ends of the lifting bars. The electric lifting telescopic rods are fixed inside the fixed base. A filling block is also installed inside the square groove. The filling block includes corner blocks, side blocks, and middle blocks. The corner blocks, side blocks, and middle blocks are arranged in a rectangular array and are located on both sides of the lifting plates or lifting bars.

[0007] The corner block, two of the side blocks, and the four corners of the middle block are all provided with sliding grooves, and the arc angle of the sliding grooves is ninety degrees.

[0008] Preferably, the fixed base also has a plurality of adjustable electric telescopic rods arranged in a rectangular array inside, an adjusting block is fixed at the top of the adjustable electric telescopic rod, and four lifting columns are fixed on the upper surface of the adjusting block.

[0009] Preferably, the lifting column is slidably engaged in the sliding groove of the corner block, side block, or middle block, and the lifting column is spliced ​​with the corner block, side block, and middle block to form a square block.

[0010] Preferably, the upper surface of the adjusting block is provided with a cross-shaped groove, and the depth of the cross-shaped groove is consistent with the height of the lifting bar.

[0011] Preferably, the height of the lifting plate is twice the height of the lifting bar, and the width of the adjusting block and the width of the lifting plate are consistent with the width of the lifting bar.

[0012] This invention uses lifting bars, half the thickness of the lifting plates, installed between the lifting plates to evenly distribute the steel bars of the barbecue grill frame. The lifting bars then descend, causing the lifting plates to drop by the thickness of one steel bar. The remaining steel bars are then placed on top of the lifting plates, ensuring that the upper and lower layers of steel bars are perpendicularly distributed. This allows for rapid positioning and assembly of the barbecue grill frame steel bars, shortening welding time and improving the welding efficiency of the barbecue grill frame.

[0013] After the steel bars used for welding the barbecue grill frame are positioned and assembled, the lifting column descends under the action of the adjusting block, allowing the welding torch to directly weld the joints between the steel bars, ensuring that the operation of the welding torch is not interfered with.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] like Figures 1 to 4 As shown, the present invention provides an automatic welding machine, including a fixed base 1. The upper surface of the fixed base 1 is provided with a square groove. Multiple lifting bars 5 are slidably installed on the inner side of the square groove. Multiple lifting plates 3 are fixed on both sides of the lifting bars 5 at equal intervals. Lifting electric telescopic rods 9 are fixed at both ends of the lifting bars 5. The lifting electric telescopic rods 9 are fixed inside the fixed base 1.

[0021] The square groove is also equipped with a filling block 2, which includes corner blocks 21, side blocks 22 and middle blocks 23. The corner blocks 21, side blocks 22 and middle blocks 23 are arranged in a rectangular array and are located on both sides of the lifting plate 3 or the lifting bar 5. A sliding groove 24 is provided at one corner of the corner block 21, two corners of the side blocks 22 and four corners of the middle block 23. The arc angle of the sliding groove 24 is ninety degrees. The lifting plate 3 and the lifting bar 5 can be used to make the steel bars used for welding the barbecue grill frame layered and vertically separated, saving the positioning time of the steel bars and improving the welding efficiency.

[0022] The fixed base 1 also has multiple rectangular arrays of adjustable electric telescopic rods 6 fixed inside. The top of the adjustable electric telescopic rod 6 is fixed with an adjusting block 7. The upper surface of the adjusting block 7 is fixed with four lifting columns 4. The lifting columns 4 are slidably engaged in the sliding groove 24 at the corner of the corner block 21, the side block 22, or the middle block 23. The lifting columns 4 are spliced ​​with the corner block 21, the side block 22, and the middle block 23 to form a square block. The lifting columns 4 can move up and down at the corner of the corner block 21, the side block 22, and the middle block 23, so that a sufficiently large gap can be left between the corner block 21, the side block 22, and the middle block 23 to ensure that the welding torch tip can smoothly weld the steel bar connection.

[0023] The upper surface of the adjusting block 7 is provided with a cross groove 8. The depth of the cross groove 8 is consistent with the height of the lifting bar 5. The height of the lifting plate 3 is twice the height of the lifting bar 5. The width of the adjusting block 7 and the width of the lifting plate 3 are consistent with the width of the lifting bar 5. The lowering height of the lifting bar 5 is controlled by the adjusting block 7 to ensure that the height of the lifting bar 5 after lowering is exactly equal to the thickness or diameter of the steel bar.

[0024] Working principle: First, connect the power supply to the device. After the power is connected, the operator places the steel bar along the length of the lifting bar 5 on the surface of the filling block 2. Then, push the steel bar to roll on the surface of the filling block 2. The rolling steel bar gets stuck in the gap between the lifting plates 3 and is located on the surface of the lifting bar 5. After all the lifting bars 5 have steel bars on their surfaces, remove the excess steel bars. Then, the electric telescopic lifting rod 9 is powered on and starts to drive the lifting bar 5 down, so that the bottom surface of the lifting bar 5 enters the adjusting block 7. At this time, the lifting plate 3 drops by one steel bar thickness or diameter.

[0025] After the lifting plate 3 descends, the workers place the remaining steel bars along the length of the lifting plate 3 and push the steel bars to roll on the surface of the filling block 2, so that the rolled steel bars fall on the upper surface of the lifting plate 3. At this time, the steel bars are layered, and the steel bars of each layer are perpendicular to each other. Next, the electric telescopic rod 6 is energized and driven to lower the adjusting block 7 and the lifting column 4 until there is a certain gap between the lifting column 4 and the bottom layer of steel bars. At this time, gaps appear between the corner block 21, the side block 22, and the middle block 23. The welding gun is used to enter this gap to weld and fix the connection of the steel bars, quickly completing the positioning and assembly of the barbecue grill frame steel bars, shortening the welding operation time, and improving the welding processing efficiency of the barbecue grill frame.

[0026] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.
