[0002] In the fields of mechanical manufacturing and construction engineering, ear plates (ear pieces), as important connecting components, are widely used in the connection of various structural members. They not only need to bear high-intensity loads but also ensure stability and accuracy during the connection process. Therefore, ear plates are usually riveted and welded together.
[0003] When splicing ear plates by riveting and welding, it is necessary to assemble and position two ear plates together. The traditional positioning method is manual positioning and fixing or clamping two ear plates together by a fixture. However, when using a fixture to splice and position two ear plates with different sizes and shapes, since the fixture can only apply a clamping force to the ear plates from the direction where the two ear plates are away from each other for positioning, if the ear plates are subjected to a force perpendicular to the clamping force, it is easy to produce an offset phenomenon.

[0022] In order to make the purpose and advantages of this utility model clearer, the following specifically describes this utility model in conjunction with embodiments. It should be understood that the following text is only used to describe one or several specific implementation manners of this utility model, and does not strictly limit the specific protection scope claimed by this utility model.
[0023] Such as Figures 1-4As shown in the figure, a positioning device for riveting and welding spliced ear plates includes a clamping member. The clamping member can be clamped and fixed at the edge position of the first ear plate 1. A vertically adjustable carriage 10 is assembled on the clamping member. A horizontally arranged second screw 11 is installed on the carriage 10, and the second screw 11 can move along the axis direction of the second screw 11 until one end of the second screw 11 abuts against the side of the second ear plate 2. At this time, by fixing the clamping member at the edge position of the first ear plate 1 and then adjusting the second screw 11 to position the side of the second ear plate 2 with the second screw 11, the second ear plate 2 can be positioned by the second screws 11 of multiple positioning devices, making the riveting holes 3 of the first ear plate 1 and the second ear plate 2 opposite, and reducing the relative displacement between the first ear plate 1 and the second ear plate 2. After positioning the first ear plate 1 and the second ear plate 2, riveting and welding treatment can be carried out.
[0024] Among them, the clamping member is a kind of fixture. Specifically, the clamping member includes a lower clamping plate 4. A vertical connecting plate 5 is fixedly connected to the rear end of the lower clamping plate 4. An upper clamping plate 6 is fixedly connected to the upper end of the vertical connecting plate 5. The lower clamping plate 4, the vertical connecting plate 5 and the upper clamping plate 6 are arranged in a C-shaped structure. A vertically arranged first screw 7 is threadedly connected to the upper clamping plate 6. A movable clamping plate 8 is installed at the lower end of the first screw 7, and the connection mode between the first screw 7 and the movable clamping plate 8 is preferably a rotational connection. When the first screw 7 rotates, the movable clamping plate 8 can be driven to move in the vertical direction until the lower end of the movable clamping plate 8 contacts the upper side of the first ear plate 1 and the upper end of the lower clamping plate 4 contacts the lower side of the first ear plate 1, and then the clamping member can be clamped on the outside of the first ear plate 1.
[0025] Among them, as Figure 1 and Figure 3 shown in the figure, a vertical sliding groove 9 is opened on the vertical connecting plate 5 and on one side of the movable clamping plate 8. A carriage 10 is vertically slidably connected inside the vertical sliding groove 9. The second screw 11 is threadedly connected to the carriage 10. At this time, when the second screw 11 rotates, the second screw 11 can move along its axis under the action of the thread between the vertical sliding groove 9 and the second screw 11 to adjust the position of the second screw 11, and the position of the second screw 11 can be locked by the thread between the vertical sliding groove 9 and the second screw 11 after the adjustment is completed.
[0026] Meanwhile, the material of at least the side wall of the carriage 10 is iron. Magnet plates 13 are fixedly connected to both side walls on both sides of the vertical sliding groove 9. The magnet plates 13 magnetically adsorb the carriage 10, so as to temporarily fix the height of the carriage 10 and the second screw rod 11. When the user clamps the clamping member on the outside of the first ear plate 1, slide the carriage 10 vertically to make the side of the second screw rod 11 opposite to the side of the second ear plate 2. Then, the carriage 10 can be magnetically adsorbed and positioned by the magnet plates 13. After the positioning is completed, by rotating the second screw rod 11, the side of the second screw rod 11 can be made to abut against the side of the second ear plate 2. Positioning the height of the carriage 10 by the magnet plates 13 can facilitate the user to operate the second screw rod 11.
[0027] Moreover, as Figures 1-3 shown, a support plate body 12 is rotatably connected to the front end of the second screw rod 11. The front end of the support plate body 12 is flat. By providing the support plate body 12, the contact area between the positioning device and the second ear plate 2 can be greatly increased, and the fixing stability can be improved.
[0028] Furthermore, as Figures 2-4 shown, the positioning device may further include a sleeve 14. Two symmetrically arranged threaded holes are formed inside the sleeve 14, and the spiral directions of the two threaded holes are opposite. Third screw rods 15 are threadedly connected to the interiors of the two threaded holes. When the sleeve 14 rotates clockwise, the two third screw rods 15 will be synchronously driven into the interiors of the threaded holes. When the sleeve 14 rotates counterclockwise, the two third screw rods 15 will be synchronously driven out of the interiors of the threaded holes.
[0029] Wherein, one ends of the two third screw rods 15 extending to the outside of the sleeve 14 are respectively detachably connected to the two lower clamping plates 4. The connection method may be that the third screw rod 15 is threadedly connected to the lower clamping plate 4, or as Figure 2 and Figure 4 shown, an L-shaped clamping seat 17 is fixedly connected to the lower side of the lower clamping plate 4. A hook 16 is fixedly connected to one end of the third screw rod 15 extending to the outside of the sleeve 14. The hook 16 can be clamped on the L-shaped clamping seat 17, so that the third screw rod 15 and the lower clamping plate 4 are connected together through the hook 16 and the L-shaped clamping seat 17.
[0030] The working principle of this utility model is as follows: Place the second ear plate 2 on the upper side of the first ear plate 1, and align the riveting and welding holes 3 of the first ear plate 1 and the second ear plate 2. Then move the clamping member so that the lower clamping plate 4 and the movable clamping plate 8 are respectively located on the upper side and the lower side of the first ear plate 1. Next, rotate the first screw rod 7 to drive the movable clamping plate 8 to move in the vertical direction, and clamp the clamping member on the outside of the first ear plate 1. After the clamping member is clamped on the outside of the first ear plate 1, slide the carriage 10 vertically so that the second screw rod 11 is opposite to the side of the second ear plate 2. Then the carriage 10 can be magnetically adsorbed and positioned by the magnetic stone plate 13. After the positioning is completed, rotate the second screw rod 11 so that the second screw rod 11 abuts against the side of the second ear plate 2, and the positioning of the first ear plate 1 and the second ear plate 2 in one direction is completed through a positioning device;
[0031] Repeat the above steps until the positioning of the first ear plate 1 and the second ear plate 2 in multiple directions is completed through multiple positioning devices, and then the riveting and welding treatment of the first ear plate 1 and the second ear plate 2 can be carried out;
[0032] In summary, this technical solution uses multiple positioning devices clamped on the first ear plate 1 to position multiple sides of the second ear plate 2, and can stably splice and position the first ear plate 1 and the second ear plate 2 with different sizes and shapes, reduce the offset phenomenon, and facilitate the user to carry out riveting and welding splicing of the first ear plate 1 and the second ear plate 2 with different sizes and shapes.
[0033] The above is only the preferred implementation manner of this utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of this utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of this utility model. The structures, devices, and operation methods not specifically described and explained in this utility model, unless otherwise specified and limited, are implemented according to the conventional means in the art.
