Description

Technical Field

[0001] This utility model relates to a positioning device, and more particularly to an auxiliary positioning device suitable for welding U-shaped clamps. Background Technology

[0002] In the construction of existing communication base stations, U-shaped clamps are often used to assist in the positioning of antenna equipment in order to meet the installation requirements. They are one of the most widely used components of antenna equipment.

[0003] To ensure overall deformation resistance, U-shaped clamps have reinforcing plates welded to their middle section during production. Currently, two reinforcing plates are conventionally used, welded together manually by hand. However, due to variations in manual operation, the reinforcing plates can shift, leading to inaccurate positioning and potentially reduced deformation resistance due to skewness, thus lowering the overall product quality. Furthermore, manual welding is slow and poses certain safety hazards.

[0004] In view of the above-mentioned shortcomings, the designer has actively researched and innovated in order to create an auxiliary positioning device suitable for the welding and processing of U-shaped clamps, so as to make it more valuable for industrial use. Utility Model Content

[0005] To solve the above-mentioned technical problems, the purpose of this utility model is to provide an auxiliary positioning device suitable for welding U-shaped clamps.

[0007] Furthermore, in the aforementioned auxiliary positioning device for welding U-shaped clamps, the limiting component consists of paired limiting side plates, which are connected to the upright plate by positioning screws.

[0008] Furthermore, in the aforementioned auxiliary positioning device for welding U-shaped clamps, the upper positioning component includes a connecting frame with side wings extending from both ends of the connecting frame.

[0011] Furthermore, in the aforementioned auxiliary positioning device for welding U-shaped clamps, the mounting mechanism includes oblong adjustment grooves mirror-distributed on the mounting plate, and a fixing hole is provided at the corresponding position of the bearing base plate. Fixing screws are connected to the adjustment grooves and fixing holes.

[0012] Furthermore, in the aforementioned auxiliary positioning device for welding U-shaped clamps, the lower positioning plate has rounded chamfers distributed on its edges.

[0013] Furthermore, in the aforementioned auxiliary positioning device for welding U-shaped clamps, the limiting mechanism is a limiting post.

[0014] Furthermore, in the aforementioned auxiliary positioning device for welding U-shaped clamps, the limiting post has a contact plane facing the upright plate, and the top of the limiting post has a rounded chamfer.

[0036] 15 U-shaped clamps with 16 reinforcing plates Detailed Implementation

[0037] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0038] like Figures 1 to 5 An auxiliary positioning device for welding U-shaped clamps includes a supporting base plate 1. Its unique feature is that vertically distributed upright plates 2 are mounted on the supporting base plate 1, and limiting components are installed on the upright plates 2 to limit the U-shaped clamp 15, facilitating temporary positioning during subsequent welding. Simultaneously, an upper positioning component 3 is movably connected to the upper end of the limiting component, and a lower positioning component 4 is connected to the lower end of the limiting component. Thus, relying on the upper positioning component 3 and the existence of the limiting components, the temporary positioning needs during the welding of the two reinforcing pieces 16 can be met. Furthermore, to prevent unnecessary displacement of the reinforcing pieces 16 and improve welding accuracy, both the upper positioning component 3 and the lower positioning component 4 are equipped with independent limiting mechanisms 5. Moreover, to facilitate the downward insertion and positioning of the U-shaped clamp 15 during subsequent processing, the ends of the upper positioning component 3 and the lower positioning component 4 facing the upright plate 2 do not contact the upright plate 2, forming an insertion space. This insertion space allows for limiting and temporarily guiding the U-shaped clamp 15.

[0039] In a preferred embodiment of this invention, the limiting components are paired limiting side plates 6. The spacing between the limiting side plates 6 corresponds to the width of the U-shaped clamp 15, and can be slightly larger than the width of the U-shaped clamp 15, facilitating smooth insertion and removal without causing jamming. Furthermore, the limiting side plates 6 are connected to the upright plate 2 via positioning screws, achieving convenient positioning. Other connection methods can also be used during implementation, which will not be elaborated here.

[0040] Furthermore, the upper positioning component 3 includes a connecting frame with side wings 7 extending from both ends. The side wings 7 are connected to the limiting component via a rotating shaft 8. This allows the upper positioning component 3 to rotate appropriately, allowing the reinforcing piece 16 to be moved aside after welding, facilitating the smooth removal of the welded U-shaped clamp 15 from the limiting component. Simultaneously, to temporarily limit the placement of subsequent upper reinforcing pieces 16, an upper limiting plate 9 extends from the connecting frame towards the vertical plate 2, with limiting mechanisms 5 distributed on the upper limiting plate 9. The edges of the upper limiting plate 9 are rounded to prevent scratching the U-shaped clamp 15. Moreover, the upper limiting plate 9 does not contact the vertical plate 2, forming a contact gap larger than the thickness of the U-shaped clamp 15, facilitating smooth insertion and removal of the U-shaped clamp 15 during processing.

[0041] In practical implementation, the lower positioning component 4 is a Z-shaped folding plate, presenting a stepped structure to facilitate subsequent lower-end positioning. The upper end of the Z-shaped folding plate forms the lower positioning plate 10, on which a limiting mechanism 5 is distributed. Simultaneously, the lower positioning plate 10 does not contact the upright plate 2, thus forming a contact gap. Furthermore, the lower end of the Z-shaped folding plate forms the mounting plate 11, which is connected to the supporting base plate 1 via a mounting mechanism. Specifically, the mounting mechanism includes oblong adjustment grooves 12 mirror-distributed on the mounting plate 11, with corresponding fixing holes on the supporting base plate 1. Fixing screws 13 are connected to the adjustment grooves 12 and fixing holes. Thus, during actual installation, the width of the contact gap can be adjusted to accommodate the thickness of the U-shaped clamp 15, meeting the needs of fine-tuning the connection. Moreover, the edges of the lower positioning plate 10 have rounded chamfers, preventing scratches on the U-shaped clamp 15.

[0042] Furthermore, to provide appropriate temporary restraint for the reinforcing plate 16, the restraining mechanism 5 is a restraining post. Its height exceeds the thickness of the reinforcing plate 16, achieving adequate blocking. Additionally, the restraining post has a contact surface facing the upright plate 2, allowing it to conform to one side of the reinforcing plate 16. During implementation, a rounded chamfer can be provided at the top of the restraining post to prevent sharp parts from scratching operators.

[0043] Meanwhile, to ensure effective levelness and prevent unnecessary skewing during welding of the reinforcing plate 16, several adjustable feet 14 are installed at the lower end of the supporting base plate 1. Specifically, each adjustable foot 14 includes guide posts distributed at the lower end of the supporting base plate 1 and extending downwards. The guide posts have threaded holes, and threaded rods are connected to the guide posts. A pad is threaded to the end of the threaded rod. Thus, after placement, the actual height difference can be adjusted via the threaded rods to ensure an effective level working surface.

[0044] The working principle of this utility model is as follows:

[0045] Insert the U-shaped clamp 15 into the limiting assembly with the inner side facing outwards. The outer edge of the U-shaped clamp 15 should contact the upright plate 2, inserted into the preset position. Finally, bring one end of the U-shaped clamp 15 into contact with the supporting base plate 1. At this point, the user can check the upper positioning assembly 3 to ensure that the upper limiting plate 9 is in a horizontal position.

[0046] Then, the two reinforcing plates 16 are placed on the upper limiting plate 9 and the lower positioning plate 10 respectively, and are temporarily limited by the corresponding limiting mechanism 5.

[0047] Subsequently, the reinforcing plate 16 is joined to the U-shaped clamp 15 by welding. During this process, the user does not need to use a positioning tool such as a clamp to temporarily limit the position of the reinforcing plate 16 with one hand, making the welding operation more convenient.

[0048] After welding is complete, simply pull the U-shaped clamp 15 upwards to achieve smooth separation. During this process, the reinforcing plate 16 at the lower end will abut against the upper positioning component 3, causing it to rotate and flip along the pivot 8 to make way. Afterwards, the user can manually flip it back to its original position.

[0049] As can be seen from the above textual description and the accompanying drawings, the present invention has the following advantages:

[0050] 1. The upper and lower positioning components can be used to temporarily position the two reinforcing plates during welding, ensuring accurate welding and preventing skewing, which facilitates the subsequent reinforcement of the U-shaped clamp.

[0051] 2. The U-shaped clamp can be placed and positioned by plugging and unplugging through the limiting component, which is convenient to use and does not affect the placement accuracy.

[0052] 3. The upper positioning component adopts a flip-and-joint method, which can meet the requirement of removal and repositioning after welding is completed without the need for user operation.

[0053] 4. Equipped with adjustable feet, it can achieve horizontal calibration after placement, ensuring the positional accuracy of the reinforcing plate welding and achieving effective load-bearing capacity.

[0054] 5. The overall structure is simple, easy to manufacture and use, and has low implementation cost.

They are only for the purpose of facilitating the description of this utility model and simplifying the description, and are not intended to indicate or imply that the device or structure referred to must have a specific orientation, or to operate in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0056] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
