Abstract
A kind of bolt mounting auxiliary, including operating head, guide portion, to vent stem and tractive unit, tractive unit is located at the tail portion of the utility model bolt mounting auxiliary, for a tapped hole, internal screw thread with to hold the external screw thread of cutting bolt mating, for auxiliary tool to be bolted with holding to cut, device to hole shank diameter is consistent with the polished rod diameter of cutting bolt is held, the usual polished rod diameter of the bolt feature bigger than screw thread nominal diameter is cut using holding, guide portion is in conical structure, for the dismounting convenient for auxiliary tool, auxiliary tool leading portion also designs a turret head boss, for dismounting auxiliary tool by tool.
Description
Technical field
The utility model relates to mechanical engineering assembly field more particularly to a kind of bolt mounting auxiliaries.
Background technique
Very widely used in mechanical engineering field bolt, the connector of screw bolt and nut composition is led usually as machinery
The connection type that domain designer considers first, this most common problem of connection type are device to hole difficulties, are generally required carefully
Device to hole rear can be inserted into bolt, commonly holds particularly with mechanical engineering field and cuts bolt, cut bolt there are one needing to holding
The problem of paying attention to is, while being inserted into bolt, it should be noted that trying not to scratch interlayer hole face and bolt light rod part, this is practical
The novel one kind that provides can assist device to hole, facilitate insertion bolt and can effectively protect the bolt peace of interlayer hole face and bolt light rod part
Fill auxiliary tool.
Summary of the invention
The technical issues of the utility model is solved is to provide a kind of bolt mounting assembly, to solve above-mentioned background technique
Described in the shortcomings that.
The technical problem solved by the utility model is implemented by the following technical solutions:
A kind of bolt mounting auxiliary, including operating head, guide portion, to vent stem and tractive unit, tractive unit is located at this reality
Be a tapped hole with the tail portion of Novel bolt mounting auxiliary, internal screw thread with to hold the external screw thread of cutting bolt mating,
For auxiliary tool to be bolted with holding to cut, device to hole shank diameter is consistent with the polished rod diameter of cutting bolt is held, and cuts bolt using holding
The usual polished rod diameter feature bigger than screw thread nominal diameter, guide portion are in conical structure, and preferably 45 ° ~ 70 ° of coning angle, be just
In the dismounting of auxiliary tool, auxiliary tool leading portion also designs a turret head boss, for dismounting auxiliary tool by tool.
In use, auxiliary tool is first loaded onto bolt, the tool of can be used is tightened in operating head, in interlayer without complete
In the case where just, bolt of the insertion with auxiliary tool simultaneously pushes away inward, by the guide portion of auxiliary tool by interlayer to just, with
Afterwards, auxiliary tool to vent stem enters interlayer hole, at this point, interlayer is being to just, then when bolt light rod part is pushed into interlayer hole just
Can more smoothly interlayer hole face or bolt light rod surface will not be damaged, after bolt is installed in place, is removed in the other side of interlayer
Auxiliary tool can install nut.The utility model can auxiliary bolt installation, and interlayer and bolt can be protected.
Detailed description of the invention
Fig. 1 is the schematic diagram of the utility model.
Fig. 2 is the operation schematic diagram of the utility model.
Specific embodiment
In order to be apparent to the utility model, below with reference to being specifically illustrating, the utility model is further described.
Referring to Fig. 1, bolt mounting auxiliary shown in Fig. 2, auxiliary tool 1 includes operating head 11, guide portion 12, device to hole
Bar 13 and tractive unit 14, tractive unit 14 are located at the tail portion of auxiliary tool 1, are threaded hole, internal screw thread and hold the external screw thread for cutting bolt 2
It is mating, consistent with the polished rod diameter of cutting bolt 2 is held to 13 diameter of vent stem for cutting bolt 2 and connecting auxiliary tool 1 with holding, benefit
The usual polished rod diameter of the bolt feature bigger than screw thread nominal diameter is cut with holding, makes that 13 tail portion of vent stem can be outputed nominal diameter and be held
The external screw thread for cutting bolt 2 is matched compared with minor thread hole, and guide portion 12 is in conical structure, preferably 45 ° ~ 70 ° of coning angle, for convenient for
The dismounting of auxiliary tool 1,1 leading portion of auxiliary tool also design an operating head 11, are turret head boss, can be convenient for tearing open by tool
Fill auxiliary tool.
In use, auxiliary tool 1 is first loaded onto bolt 2, the tool of can be used is tightened in operating head 11, is not necessarily in interlayer
Completely in the case where just, bolt of the insertion with auxiliary tool simultaneously pushes away inward, by the guide portion 12 of auxiliary tool 1 by interlayer pair
Just, then, auxiliary tool 1 to vent stem 13 enters interlayer hole, at this point, interlayer is being to just, then 2 smooth bar part of bolt is pushed into and is pressed from both sides
More smoothly 2 polished rod surface of interlayer hole face or bolt will not can be damaged, after bolt 2 is installed in place, in interlayer when layer hole
Auxiliary tool 1 is removed in the other side can install nut, realize connection.Not only interlayer hole can have been assisted to just, but also the installation of bootable bolt,
Interlayer and bolt can also be protected.
