Description

Technical Field

[0001] The utility model relates to a sand vibrating clamping tool for a fuse. Background Art

[0002] Low voltage fuses are widely used in low voltage distribution systems and control systems, mainly for short circuit protection, and are also one of the important protection components of a single electrical device. Low voltage fuses have simple structure, small size, light weight, low price, high breaking capacity and good current limiting characteristics. When used with other low voltage electrical appliances, they have good technical and economic effects.

[0003] The main production processes of low-voltage fuses include: melt punching, melt spot welding, fuse assembly, fuse vibration loading of quartz sand, liquid glue injection, drying and curing, and packaging. In the process of fuse vibration loading, the contact blade and cover plate coating of the fuse are often worn due to improper clamping, which affects the appearance quality of the product. This new type is designed to solve the problem of contact blade and cover plate coating wear encountered in the vibration process of a structural fuse of the NT series, and is a fuse vibration clamping tool. Utility Model Content

[0004] The utility model aims to provide a fuse vibrating sand clamping tool to solve the above technical problems.

[0005] To achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A fuse vibrating sand clamping tool comprises a vertical plate A, a vertical plate B, a reinforcing rod, a clamping nut, a clamping hexagon socket head screw, a convex edge support positioning plate A, a support positioning plate B, and a side positioning plate. Six reinforcing rods are equidistantly bolted between the vertical plate A and the vertical plate B, four of the clamping nuts are equidistantly fixedly connected to the upper front of the vertical plate A, the clamping hexagon socket head screw is bolted inside the clamping nut, four of the convex edge support positioning plates A are equidistantly bolted between the vertical plate A and the vertical plate B, and two of the side positioning plates are respectively bolted between two groups of convex edge support positioning plates A.

[0007] Based on the above technical solution, the vertical plate A and the vertical plate B include fuse workpieces and spacers, and multiple fuse workpieces are placed between the protruding edge support positioning plate A and the support positioning plate B, and the spacers are placed between each fuse workpiece.

[0008] On the basis of the above technical solution, the vertical plate A, vertical plate B, reinforcing rod, clamping nut and clamping hexagon socket head screw are made of steel, and other workpieces in contact with the fuse workpiece and spacers are made of epoxy resin; the clamping nut is fixed on the vertical plate A and has a non-continuous thread, and the clamping nut has a structure similar to a die.

[0009] Compared with the prior art, the utility model has the following advantages: the utility model is mainly used to clamp fuses, and the spacer is used to separate the fuses clamped on the fixture to ensure a certain gap between the easily worn surfaces, so that no hard friction or collision occurs when the fuses are vibrated, resulting in wear of the coating of the cover plate or the contact knife.

[0014] The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0015] like Figure 1-3 As shown, a fuse vibrating sand clamping tool comprises a vertical plate A1, a vertical plate B2, a reinforcing rod 3, a clamping nut 4, a clamping hexagon socket head screw 5, a convex edge support positioning plate A6, a support positioning plate B7, and a side positioning plate 8. Six reinforcing rods 3 are equidistantly bolted between the vertical plate A1 and the vertical plate B2, four of the clamping nuts 4 are equidistantly fixedly connected above the front face of the vertical plate A1, the clamping hexagon socket head screw 5 is bolted inside the clamping nut 4, four of the convex edge support positioning plates A6 are equidistantly bolted between the vertical plate A1 and the vertical plate B2, and two of the side positioning plates 8 are respectively bolted between two groups of convex edge support positioning plates A6.

[0016] The vertical plate A1 and the vertical plate B2 include fuse workpieces 9 and spacers 10 . A plurality of fuse workpieces 9 are placed between the convex support positioning plate A6 and the support positioning plate B7 , and the spacers are placed between the fuse workpieces 9 .

[0017] The vertical plate A1, the vertical plate B2, the reinforcing rod 3, the clamping nut 4 and the clamping hexagon socket head screw 5 are made of steel, and the other workpieces in contact with the fuse workpiece 9 and the spacer 10 are made of epoxy resin; the clamping nut 4 is fixed on the vertical plate A1 and has a discontinuous thread. The clamping nut 4 has a structure similar to a die.

[0018] Working principle of the utility model: the new type of fixture uses the non-marked porcelain tube surface and the screw head surface of the non-sand hole surface of the fuse as the positioning and clamping surface, and other easily worn surfaces are kept at a certain gap with the fixture, so that these easily worn surfaces are only in contact with quartz sand during sand vibration, and the floating quartz sand can ensure that the coating of the easily worn surface is not easily damaged during sand vibration, and the printed porcelain tube surface is used as the easily worn product identification of the clamping surface; both the vertical plate A and the vertical plate B have two φ10 holes for installing handles, which is convenient for the use of the fixture; the clamped workpiece has a certain gap with the fixture except for the positioning and support points, which can ensure that the easily worn surface of the workpiece does not rub against the fixture during vibration, resulting in coating wear. After the clamped fixture is installed in the sand vibration groove on the vibration table, add quartz sand and it can be used normally.

[0019] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
