Abstract
Description
Technical Field
[0001] This utility model relates to the field of mechanical parts technology, and in particular to a multi-functional positioning frame for bushing positioning and welding. Background Technology
[0002] Currently, in the assembly process of products such as cranes and pump trucks, more and more welded parts need to ensure the coaxiality of the inner holes of two, three or more sleeve parts to ensure higher assembly accuracy.
[0003] In the existing technology, when welding bushing parts, it is also necessary to position the bushing and the workpiece to be welded. The existing auxiliary positioning method is simply to set a limiting plate on the long shaft to limit the bushing. It needs to be simple in structure, but it still has the following shortcomings: 1. The position of the bushing positioning is not adjustable, and the versatility is poor; 2. The limiting plate will block the welding position to a certain extent, which is not convenient for welding work. Utility Model Content
[0004] The present invention aims to at least partially solve one of the problems existing in the existing related technologies. To this end, the present invention proposes a multi-functional positioning frame for bushing positioning and welding.
[0005] To achieve the above objectives, this utility model provides the following technical solution:
[0006] A multi-functional positioning frame for bushing positioning and welding includes a positioning plate, the positioning plate having a central hole and an eccentric hole on one side of the central hole, a sleeve being fitted inside the central hole, and a threaded hole penetrating the outer wall of the sleeve.
[0007] In some embodiments, multiple eccentric holes are provided.
[0008] In some embodiments, the positioning plate includes a central annular plate and extension plates symmetrically disposed on the outer wall of the central annular plate, the central hole being disposed on the central annular plate and the eccentric hole being disposed on the extension plates.
[0009] In some embodiments, multiple threaded holes are provided.
[0010] In some embodiments, the sleeve is fixed to the central hole by welding.
[0011] Compared with the prior art, the beneficial effects of this utility model are:
[0012] A sleeve is fixedly installed in the center hole of the positioning plate, and a threaded hole is provided on the outer wall of the sleeve. During installation, the sleeve is fitted onto the long shaft, and the position of the sleeve can be adjusted according to the actual situation. After the position is determined, a bolt is directly screwed into the threaded hole, and the bolt is tightened onto the long shaft to fix it. This method has strong versatility and can fix the positioning plate to ensure the welding position of the bushing or other workpieces. In addition, an eccentric hole is also provided on the positioning plate. The eccentric hole can reduce the weight of the positioning plate and can also be used to weld the bushing or other workpieces, thus facilitating the welding work. Attached Figure Description

[0017] The following detailed description provides various embodiments or examples for implementing this utility model. Of course, these are merely embodiments or examples and are not intended to be limiting. Additionally, repeated reference numerals, such as repeated numbers and / or letters, may be used in different embodiments. These repetitions are for the purpose of simple and clear description of this utility model and do not represent a specific relationship between the different embodiments and / or structures discussed.
[0018] like Figures 1-4 The multi-functional positioning frame for bushing positioning and welding shown includes a positioning plate 1, a central hole 2 and an eccentric hole 3 on one side of the central hole 2, a sleeve 4 is fitted inside the central hole 2, and a threaded hole 5 is passed through the outer wall of the sleeve 4.
[0019] The multifunctional positioning frame of this utility model has a sleeve 4 fixedly installed in the center hole 2 of the positioning plate 1, and a threaded hole 5 provided on the outer wall of the sleeve 4. During installation, the sleeve 4 is sleeved on the long shaft (not shown in the attached figure). Then, the position of the sleeve 4 and the positioning plate 1 can be adjusted according to the actual situation. After the position is determined, the bolt is directly screwed into the threaded hole 5, and the bolt is tightened on the long shaft to fix it. It has strong versatility and thus fixes the positioning plate 1 to ensure the position of the bushing or other workpieces for welding. In addition, the positioning plate 1 is also provided with an eccentric hole 3. The eccentric hole 3 can reduce the weight of the positioning plate 1, and the bushing or other workpieces can be welded in the eccentric hole 3, which facilitates the welding work.
[0020] See Figures 1-2 The positioning plate 1 includes a central ring plate 31 and extension plates 32 symmetrically arranged on the outer wall of the central ring plate 31. Two eccentric holes 3 are symmetrically arranged, and the eccentric holes 3 are respectively arranged on the extension plates 32. The central ring plate 31 and the extension plates 32 on both sides are integrally formed of iron material.
[0021] The bushing or other welded workpieces can be positioned by the extension plate 32. Then, the upper and lower sides of the bushing or other welded workpieces can be pre-welded by the eccentric holes 3 on the upper and lower sides. At the same time, the central ring plate 31 will not block the bushing or other welded workpieces, so pre-welding can also be carried out on the left and right sides of the bushing or other welded workpieces. This increases the pre-welding area of the bushing or other welded workpieces, ensuring that they will not deform in subsequent welding and improving the overall accuracy.
[0022] Furthermore, the central hole 2 is located in the central annular plate 31, and the sleeve 4 is fixed in the central hole 2 within the central annular plate 31 by welding.
[0023] To ensure the stability of the sleeve 4 and the positioning plate 1 when positioned on the long axis, the threaded hole 5 is provided with multiple holes.
[0024] Based on the accompanying drawings and the foregoing display and description of 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 claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
