Description

Male nut fastening tool suitable for clamp spring structure
Technical Field
The utility model belongs to the field of mechanical installation tools, and particularly relates to a male nut fastening tool suitable for a clamp spring structure.
Background
The male nut structure is similar to a set screw and is of a full external thread structure. Set screws are also known as standoff screws and set screws. Is a screw special for fixing the relative position of a machine part. The types mainly comprise square head flange end set bolts, GB/T821-1988 square head chamfer end set bolts, GB/T85-1988 square head long cylinder end set bolts, inner square head set bolts and the like.
The set screw is generally fastened by adopting an internal hexagonal wrench or a straight screwdriver, but part of the set screw is arranged in a specific screw hole, the end face of the male nut is required to be parallel to the screw hole, in order to realize smooth disassembly of the male nut, two symmetrical blind holes are usually required to be formed in the end part of the nut, and the nut is twisted by using a clamp spring pliers to realize disassembly (as shown in figure 1). If the male nut has a tightening torque requirement, the torque requirement of the male nut cannot be met by using the clamp spring pliers.
Disclosure of Invention
In view of the technical problems existing in the background art, the male nut fastening tool suitable for the clamp spring structure provided by the utility model not only can realize quick assembly and disassembly of the male nut, but also can realize functions of torque measurement, fixed moment installation and the like through torque transmission.
In order to solve the technical problems, the utility model adopts the following technical scheme:
The utility model provides a male nut fastening frock suitable for jump ring structure, includes the nut body and screws up the pin, and the through hole has been seted up to the axle center department of nut body, and the mounting hole has been seted up to the up end of nut body, the mounting hole is annular symmetric distribution around the through hole, screws up the one end grafting of pin in the mounting hole, screws up the other end grafting of pin in the blind hole on the male nut, the nut body passes through screw up pin transmission moment of torsion.
In the preferred scheme, tightening grooves are formed in the outer wall of the tightening pin at equal intervals, and rubber rings are sleeved in the tightening grooves.
In the preferred scheme, the outer wall department symmetry of nut body has offered and has been accomodate the groove, and the card is put in accomodating the inslot when tightening the pin idle.
The following beneficial effects can be achieved in this patent:
1. According to the tool, the nut body is combined with the male nut, the male nut can be quickly assembled and disassembled by matching with the spanner, and the end face of the male nut is parallel to the screw hole;
2. The tool can enable the torque wrench to replace the clamp spring pliers to realize nut dismounting work through torque transmission, and can realize torque measurement and torque fixing installation work through the torque wrench and the monitoring device;
3. the inside groove of accomodating that sets up of frock can avoid the pin to lose.
Drawings
The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
FIG. 1 is a prior art male nut mounting pattern of the present utility model;
FIG. 2 is a diagram of the connection of the male nut and the tool of the present utility model;
FIG. 3 is a schematic view of the structure of the nut body and the tightening pin (connected state) of the present utility model;
FIG. 4 is a schematic view of the structure of the nut body and the tightening pin (in the stored state) of the present utility model;
fig. 5 is an enlarged schematic view of the structure of the tightening pin of the present utility model.
In the figure: screw hole 1, male nut 2, blind hole 3, jump ring pincers 4, nut body 5, through-hole 6, screw up pin 7, mounting hole 8, storage tank 9, binding groove 10, rubber circle 11.
Detailed Description
As shown in fig. 2 and 3, a male nut fastening tool suitable for a snap spring structure comprises a nut body 5 and a tightening pin 7, wherein a through hole 6 is formed in the axis of the nut body 5, mounting holes 8 are formed in the upper end face of the nut body 5, the mounting holes 8 are symmetrically distributed annularly around the through hole 6, one end of the tightening pin 7 is inserted into the mounting holes 8, the other end of the tightening pin 7 is inserted into a blind hole 3 in the male nut 2, and the nut body 5 transmits torque through the tightening pin 7;
In order to ensure that the end face of the male nut 2 is parallel to the screw hole 1, as shown in fig. 1, the male nut 2 cannot be assembled or disassembled by using tools such as a wrench, and in order to solve the above problem, two symmetrical blind holes 3 are usually formed at the end face of the male nut 2, and then the blind holes 3 are clamped by a clamp spring clamp 4 and the male nut 2 is twisted to realize the assembly or disassembly;
When the scheme is adopted, when the male nut 2 is required to be disassembled and assembled, the male nut 2 and the nut body 5 can be connected into a whole only by inserting the tightening pin 7 into the nut body 5 and inserting the other end of the tightening pin 7 into the corresponding blind hole 3, then the nut body 5 is twisted by a torque wrench, the quick disassembly and assembly of the male nut 2 can be completed, and the torque measurement, the torque fixing installation and other works can be realized by twisting the nut body 5.
The preferable proposal is as shown in figure 5, the outer wall of the tightening pin 7 is provided with tightening grooves 10 at equal intervals, the tightening grooves 10 are sleeved with rubber rings 11,
Because the external diameter of the rubber ring 11 is slightly larger than the external diameter of the tightening pin 7, the rubber ring 11 is fixed in the tightening slot 10 and can avoid sliding up and down, and when the tightening pin 7 is inserted into the mounting hole 8 and the blind hole 3, the rubber ring 11 is internally contracted and extruded, so that the tightening pin 7 is prevented from sliding out of the mounting hole 8.
As shown in fig. 4, the outer wall of the nut body 5 is symmetrically provided with a storage groove 9, and the tightening pin 7 is blocked in the storage groove 9 when in idle;
When the frock is idle, can will screw up pin 7 and pull out in the mounting hole 8, will screw up pin 7 again and place in accomodating groove 9, screw up pin 7 and can fix in accomodating groove 9 and can not roll off through rubber circle 11, avoid screwing up pin 7 and lose, screw up pin 7 and adopt the nickel base alloy material generally, intensity is big, hardness is high, every 2 are a set of, can prepare the multiunit in the use, when screw up the pin damage, can in time change.
The above embodiments are only preferred embodiments of the present utility model, and should not be construed as limiting the present utility model, and the scope of the present utility model should be defined by the claims, including the equivalents of the technical features in the claims. I.e., equivalent replacement modifications within the scope of this utility model are also within the scope of the utility model.
