Abstract

(57) [Problem] To improve the necessity of attaching and detaching a nut to be attached to a thread portion of a bolt or a shaft from a tip portion of the thread. SOLUTION: An exploded nut which can be detached from an arbitrary portion of a bolt or a thread portion of a shaft is used.

Description

[Detailed description of the device]

[0001]

[Technical field to which the device belongs]

  The present invention relates to a tightening nut used for a bolt or a shaft. It is a thing.

[0002]

[Prior art]

  Conventionally, hexagonal nuts made of metal have been widely used. Assemble the machine by mounting it on the table and tightening it with a tightening tool such as a spanner. Is used as a fixture.

[0003]

[Problems to be solved by the device]

  Conventional nuts have short screw threads on the bolt or shaft and can be easily installed and removed. Suitable for one, but a single long bolt or bolt with long threads. In a chaft, a variety of nuts are used to fix various things at certain intervals. In the case of complicated precision machinery or equipment, The nut cannot be removed, and all nuts should be removed once for overhauling or inspection and adjustment. If you do not remove it, you may not be able to perform it and you may have to completely disassemble. Labor is required.

[0004]   Also, depending on the machine, there may not be enough space for the nut to be removed or Nuts and bolts threaded parts due to excessive tightening with attachments or rusting May be damaged and cannot be reused, and in the worst case, cannot be repaired and a total replacement is required. Has occurred.

[0005]

[Problems to be solved by the device]

  If the nut cannot be disassembled, be sure to remove the bolt or shaft when attaching or detaching. If it requires a great deal of work as it must be carried out from the tip of the thread, However, by using the disassembled and assembled nut, you can It is not necessary to remove the nut from the screw thread tip of the It can be detached from the middle of the process, and complicated machinery and equipment can be disassembled, repaired or adjusted. The time is greatly reduced.

[0006]   Also, by disassembling and assembling nuts, you can If there is a risk of damage if the nut is forcibly turned due to rust on the thread portion of the , The nut can be easily disassembled and removed at any point, so the bolt It is possible to protect the shaft thread portion.

[0007]

[Means for Solving the Problems]

  This invention is a bolt or shaft by disassembling the nut. The purpose is to allow the nut to be attached and removed at any point along the thread. The shape varies depending on the strength required for the nut body in.

[0008]   If the strength of the nut body is not required, the split nut is made of resin and the Adopts a method that can be easily assembled with adhesive etc., but resin screw threads If there is a risk of damage to the parts, make the outside of the holder barrel made of resin and only the thread It is desirable to use a metal sleeve system and assemble and use both together. Yes.

[0009]   When general nut strength is required, the metal is divided into 2 or 3 parts. Uses nuts that are assembled with connecting auxiliary bolts etc. To do.

[0010]   Alternatively, the outer metal holder and the inner threaded sleeve part Use nuts that are assembled with auxiliary connecting bolts.

[0011]   The strength of the above nuts depends on the thickness of the nut, the material or the strength of the connection auxiliary bolt, Adjust by number.

[0012]   For the high-speed rotating body, the assembled nut is heavy to prevent vibration. The structure should be left-right symmetrical so that there is no segregation.

[0013]

[Embodiment of device]

  Figure 1 shows a resin two-piece assembly outside when the strength of the nut body is not required. Consists of a side holder and a two-piece assembly sleeve part with metal threads It is a disassembled and assembled nut, and the connection between the holder part and the sleeve part is a hexagonal joint surface and And holder projections and sleeve connection holes. Holder protrusion and The connection method of the sleeve connection hole is for simplification, and it is recommended to use the connection auxiliary bolt. desirable.

[0014]   Fig. 2 shows that when the strength of a general nut body is required, the nut divided into two is The convex joint surfaces are aligned and fixedly connected by connecting auxiliary bolts.

[0015]   Fig. 3 shows a two-piece metal assembly when the strength of a general nut body is required. The outer holder and the two-part assembly sleeve part with metal threads It is a disassembled and assembled nut that has a hexagonal connection between the holder and sleeve. The surface and the connection auxiliary bolt are used.

[0016]   The selection of the above disassembled and assembled nut is decided according to the intended use. Also, the shape is not limited to hexagon. If the number of divisions is two, the threads will get in the way It may be difficult to assemble and disassemble, but it may be desirable to divide it into 3 parts. I don't care about the number.

[0017]

[Effect of device]

  The present invention allows the nut to be freely installed from any location on the bolt or shaft thread. It can be put on and taken off, and the labor for disassembly, repair and adjustment is greatly reduced.

[0018]   Also, by using the middle of the ceiling hanging bolts used for other purposes, Can be additionally fixed and can be used without disassembling the currently used part at the bottom. In addition, it is possible to add optional fixing members, forget to put in the required number of nuts, etc. It

[0019]   It is possible to reduce the weight of each member by making the heavy nut a split assembly type. The handling is improved.
