Description

Technical Field

[0001] This utility model relates to the field of welding technology, and more specifically, to a positioning device for welding oil cups. Background Technology

[0002] As a core kitchen appliance, the range hood's oil cup is a crucial component for collecting condensed grease and fumes, directly impacting the appliance's cleanliness and lifespan. Range hood oil cups are mostly made of metal components, which must be seamlessly connected through welding. Therefore, the welding quality directly determines the oil cup's sealing performance (preventing oil leakage) and structural strength (avoiding long-term deformation under load). The positioning device used in the oil cup welding is the core equipment ensuring welding precision, and its performance plays a decisive role in the production efficiency and product quality of range hood oil cups.

[0003] Currently, the oil cup of a range hood is generally welded point by point using a single spot welding machine. The positioning of the metal plates during the welding process is done manually, with each metal plate being aligned and fixed by hand before welding.

[0004] However, the above-mentioned manual operation not only makes the oil cup assembly process complex, time-consuming, and labor-intensive, but also involves subjective judgment when aligning the various metal plates, which can lead to inaccurate alignment and a high error rate. This can result in quality defects such as gaps or incomplete welds in the oil cup after welding, affecting the product's sealing performance and structural strength, and may also cause oil leakage during use, seriously affecting the quality of the finished oil cup. Utility Model Content

[0005] The purpose of this invention is to overcome the shortcomings and deficiencies in the existing technology and provide a simple and practical positioning device for welding oil cups. This positioning device can replace manual operation and accurately fix and align the oil cups, thereby improving the welding accuracy and assembly efficiency of the oil cups, and further improving the efficiency of subsequent welding and the quality of the finished oil cups.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a positioning device for welding oil cups, characterized in that: it is used to press and position the bottom plate forming the oil cup, the side plate one and the side plate two forming the oil cup, and the end plate one and the end plate two forming the oil cup, so as to facilitate welding; the positioning device includes a worktable and at least one positioning unit installed on the worktable; each positioning unit includes two inner support blocks for supporting the bottom plate, a downward positioning mechanism for positioning the bottom plate and the side plate one, a side positioning mechanism for positioning the side plate two, and an end positioning mechanism for positioning the end plate one and the end plate two; Two inner support blocks are movably mounted on the worktable to adjust the spacing; the pressing positioning mechanism is detachably connected to the worktable and positions the bottom plate and side plate one on the inner support blocks; the side positioning mechanism is detachably connected to the worktable and positions side plate two on the inner support blocks; the end positioning mechanism is mounted on the worktable and positions end plate one and end plate two on the inner support blocks.

[0007] In the above scheme, the inner support block supports the bottom plate of the oil cup. The bottom plate, side plate one, side plate two, end plate one, and end plate two are pressed and positioned onto the inner support block by the pressing positioning mechanism, side positioning mechanism, and end positioning mechanism, facilitating subsequent welding. Therefore, this positioning device can replace manual labor for accurate positioning of the oil cup, thereby improving the welding accuracy and assembly efficiency, and consequently improving the efficiency of subsequent welding and the quality of the finished product. Furthermore, the two inner support blocks can be moved and mounted on the worktable to adjust the spacing, accommodating welding and positioning of oil cups of various lengths. The pressing positioning mechanism and side positioning mechanism can also be disassembled and adjusted accordingly.

This means that the positioning device also includes a sliding mechanism equal in number to the inner support blocks. Each sliding mechanism includes a sliding component, a sliding drive component, and a connecting block. The sliding component is mounted on the worktable and connected to the inner support blocks. The sliding drive component is connected to the worktable and to the inner support blocks through the connecting block, thereby driving the inner support blocks to move and adjust the spacing between the two inner support blocks.

[0009] The sliding assembly includes a guide rail and a slider; the guide rail is set on the worktable, and the slider is connected to the inner support block and slidably connected to the slider.

[0010] The workbench has a limiting groove, and the connecting block extends out of the limiting groove and connects with the inner support block.

[0011] The detachable connection between the pressing positioning mechanism and the worktable means that the positioning device also includes a mounting frame; the pressing positioning mechanism of each positioning unit is respectively set on the mounting frame, and the mounting frame is detachably connected to the worktable.

[0012] The pressing and positioning mechanism includes a pressing drive component and a pressing block; the pressing drive component is mounted on the mounting frame and located above the inner support block; the pressing block matches the bottom plate and the first side plate; the pressing drive component is connected to the pressing block to drive the pressing block to descend and press the bottom plate and the first side plate against the inner support block.

[0013] The side positioning mechanism includes a pad, a side driving component, and a side pressing block; the pad is detachably connected to the worktable; the side driving component is disposed on the pad and connected to the side pressing block, thereby driving the side pressing block to move and press the side plate to the inner support block.

[0014] The end positioning mechanism includes a mounting block, an end driving component, and an end pressing block; the mounting block is fixedly connected to or detachably connected to the worktable; the end driving component is disposed on the mounting block and connected to the end pressing block, thereby driving the end pressing block to move and press end plate one / end plate two to the inner support block.

[0015] The length of the limiting groove of this utility model can be determined according to the driving stroke of the end driving component. If the length of the limiting groove matches the driving stroke of the end driving component, the mounting block can be fixedly connected to the worktable.

[0016] In each positioning unit, at least one intermediate positioning block for supporting the middle part of the base plate is provided between the two inner support blocks; the intermediate positioning block is set on the worktable; the intermediate positioning block matches the inner wall of side plate one, side plate two and the base plate; Two internal support blocks are arranged in a mirror symmetrical manner; one internal support block matches the inner wall of side plate one, side plate two, bottom plate and end plate one; the other internal support block matches the inner wall of side plate one, side plate two, bottom plate and end plate two.

[0018] The workbench is equipped with support legs and casters for easy movement; the casters are equipped with foot brakes; and the support legs are height-adjustable. When the workbench needs to be moved, the height of the support legs can be adjusted to lift them off the ground, allowing the workbench to move via the casters to the welding station. When the workbench needs to be fixed, the casters can be secured using the foot brakes, and the height of the support legs can be adjusted to bring them into contact with the ground, thus ensuring the workbench is stable on the ground.
