Description

Technical Field

[0001] This application relates to the field of fuse manufacturing technology, specifically to a fuse assembly mechanism. Background Technology

[0002] As a short-circuit and overcurrent protector widely used in high and low voltage power distribution systems, control systems, and various electrical equipment, fuses are one of the key components ensuring circuit safety. The assembly process is particularly important in fuse manufacturing. In existing technologies, the fuse assembly process is quite cumbersome. First, a gasket is placed on the ceramic tube, then a contact blade is placed on the gasket, followed by tightening the cover plate screws. Then, the fusible element is welded to the middle step of the contact blade. After welding, the cover plate screws are removed, the cover plate is placed, the cover plate screws are pre-tightened, and finally, they are tightened. This process has several problems: on the one hand, the flatness of the cover plates at both ends after installation is significantly different, making it difficult to guarantee product consistency; on the other hand, the pre-tightening and then tightening operation of the cover plate during installation can easily cause tilting during tightening, affecting not only the product's appearance quality but also the positioning and installation of the indicator. Furthermore, there is a risk of the fusible element being pulled and broken when the product is flipped during assembly, and the entire assembly process is time-consuming, greatly impacting production efficiency. These problems seriously restrict fuse manufacturers from improving product quality and increasing production efficiency. Utility Model Content

[0003] The purpose of this application is to address the aforementioned problems in the prior art by providing a fuse assembly mechanism. Through the coordinated operation of a fixture positioning mechanism, a clamping mechanism, and a flipping limit block, the fuse assembly process is simplified, product consistency and assembly efficiency are improved, and the risk of fuse damage is reduced. This solves the defects of existing fuse assembly technologies, such as large differences in the flatness of the cover plate after assembly, easy tilting during installation, easy breakage of the fuse, and long assembly time.

[0004] To achieve the above-mentioned objectives, this application adopts the following technical solution: A fuse assembly mechanism includes:

[0005] The fixture positioning mechanism is provided with a positioning groove that mates with the cover plate of the fuse semi-finished product and a threaded hole for fixing the fuse semi-finished product.

[0006] The clamping mechanism, located on the fixture positioning mechanism, is used to clamp the fuse semi-finished product;

[0007] The fixture bottom fixing mechanism is rotatably connected to the fixture positioning mechanism.

[0008] Furthermore, the fixture bottom fixing mechanism is connected to the fixture positioning mechanism via a connecting plate.

[0009] Further, the jig bottom fixing mechanism top is provided with a rotating hole, the rotating hole is installed with a rotating shaft through a shaft sleeve, and the end face of the rotating shaft away from the jig positioning mechanism is connected with a connecting plate.

[0010] Further, the connecting plate is provided with a first turnover limiting block for limiting the rotation angle of the jig positioning mechanism, and the jig bottom fixing mechanism is provided with a second turnover limiting block matched with the first turnover limiting block.

[0011] Further, the rotating shaft is limited to move axially through a shaft limiting block.

[0012] Further, the pressing mechanism comprises a driving member installed on the connecting plate, a pressing block installed on the output end of the driving member, and a plurality of elastic pressing heads arranged on the pressing block.

[0013] Further, the driving member is a gas cylinder or an electric cylinder.

[0014] Further, the number of elastic pressing heads is four.

[0015] Further, the end face of the rotating shaft away from the jig positioning mechanism is connected with the connecting plate through a screw.

[0016] Compared with the prior art, the utility model has the advantages that:

[0017] 1. Precise and stable positioning: the jig positioning mechanism cooperates with the fuse semi-finished cover plate through the positioning groove, and is fixed in combination with the threaded hole, so that the position of the fuse semi-finished product is accurate during assembly, and deviation is avoided, thereby solving the problem of inaccurate assembly positioning in the prior art.

[0018] 2. Uniform and reliable pressing: the elastic pressing heads of the pressing mechanism can adapt to the surface of the fuse, cooperate with the driving member (gas cylinder or electric cylinder) to provide stable pressure, uniformly press the fuse, avoid the cover plate inclination problem in the traditional tightening process, and improve the product appearance quality and assembly consistency.

[0019] 3. Precise rotation control: the first turnover limiting block and the second turnover limiting block are matched to accurately limit the rotation angle of the jig positioning mechanism, and prevent the fuse from being broken due to excessive turnover; at the same time, the rotating shaft is limited to move axially through the shaft limiting block, so as to ensure the stability of the rotating structure and improve the reliability of the assembly process.

[0020] 4. Structure cooperation improves efficiency: the jig bottom fixing mechanism, the connecting plate, the rotating shaft and other components cooperatively constitute a rotating connection structure, simplify the assembly process, effectively shorten the assembly time compared with the traditional complicated assembly process, and improve the production efficiency.

When the jig positioning mechanism 1 rotates, the first overturning limiting block 8 and the second overturning limiting block 9 abut against each other, so as to accurately limit the rotation angle, such as 180°, and avoid excessive overturning.

[0033] The rotation shaft 7 is limited in axial movement by the shaft limiting block 10, so as to ensure the stability of the structure in the rotation process and prevent the axial deviation from affecting the assembly accuracy.
