Abstract
A kind of rotation bolt of steering column is done over again with tooling, including sleeve, steering column is inserted into one end of sleeve, and the other end of sleeve then offers a sleeve pedestal, the diameter of sleeve pedestal be more than steering column internal diameter, the sleeve pedestal as a step-shaped top steering column opening；Sleeve is provided with a rotary type mandrel inside it, and the opening that one end of the rotary type mandrel is inserted into one end of steering column from sleeve is stretched out, and is connected with a threaded rod, the just right rotation bolt to be done over again of the threaded rod；One end of the close sleeve pedestal of rotary type mandrel is provided with rotating handles 3a, and rotary type mandrel and sleeve pedestal are fixed connection.Threaded rod is screwed in the threaded hole of rotation bolt to be done over again by rotation rotating handles, and as threaded rod is transferred to going deep into for threaded hole by rotary type mandrel, since rotary type mandrel and sleeve pedestal are fixed connection, sleeve pedestal withstands steering column and generates reaction force, and rotation bolt is extracted.
Description
Technical field
The utility model is related to parts assembly fields more particularly to a kind of rotation bolt applied to steering column to do over again
Use tooling.
Background technology
Currently, in the steering column assembling process of automobile steering device, because the concentricity of numerically-controlled machine tool has error, raw material
The many factors such as the problem of difference, product itself can cause the position of the rotation bolt of steering column that cannot meet on drawing and want
It asks, as substandard product.
For example, certain tubing string is connected together bottom plate with cast tube by rotating bolt.It wants position after rotation bolt indentation
Entire tubing string small assembly can be led to for 2.4 ± 0.25mm if the indentation distance of rotation bolt exceeds error criterion by asking when serious
Scrap, generate the waste of larger raw materials for production, improve production cost, it is therefore necessary to rotation bolt compression distance it is wrong
The tubing string of difference carries out reworked processing.
Due to being all interference fit between the rotation connection workpiece such as bolt and bottom plate, cast tube, and the power being pressed into is bigger.
Traditional reworking method is to use general utility tool such as vice etc. by manpower, by force extracts rotation bolt, does so not only
It is time-consuming and laborious, and tubing string can be made because being generated hidden danger of quality by impact force in process of rework, cause the matter of turning machine finished product
Amount declines.
Utility model content
To solve the above-mentioned problems, the utility model provides a kind of rotation bolt of steering column and does over again with tooling,
Simple in structure, service efficiency is high, and impact force is not generated during use, can effectively eliminate tubing string hidden danger of quality, improves and turns to
Machine final product quality.
A kind of rotation bolt of steering column of the utility model is done over again with tooling, and concrete structure is as described below：
A kind of rotation bolt of steering column is done over again with tooling, including sleeve, it is characterised in that：
Steering column is inserted into one end of the sleeve, and the other end of sleeve then offers a sleeve pedestal, sleeve pedestal
Diameter be more than steering column internal diameter, the sleeve pedestal as a step-shaped top steering column opening；
The sleeve is provided with a rotary type mandrel inside it, and one end of the rotary type mandrel is inserted into from sleeve
The opening of one end of steering column is stretched out, and is connected with a threaded rod, the just right rotation spiral shell to be done over again of the threaded rod
Bolt；
One end of the close sleeve pedestal of the rotary type mandrel is provided with rotating handles, and rotary type mandrel with
Sleeve pedestal is fixed connection.
A kind of rotation bolt of steering column according to the present utility model is done over again with tooling, which is characterized in that described can
Threaded rod is screwed in the threaded hole of rotation bolt to be done over again by rotary mandrel by rotating its rotating handles, and with can revolve
Threaded rod is transferred to going deep into for threaded hole by rotatable mandrel, since rotary type mandrel and sleeve pedestal are fixed connection, sleeve
Pedestal withstands steering column and generates reaction force, and rotation bolt is extracted.
Threaded rod is main stressed member, be can be changed quickly.
It is done over again using a kind of rotation bolt of steering column of the utility model and obtains following advantageous effect with tooling：
A kind of rotation bolt of steering column of the utility model is done over again with tooling, simple in structure, and service efficiency is high, makes
With impact force is not generated in the process, tubing string hidden danger of quality can be effectively eliminated, improves turning machine final product quality.
Description of the drawings
Fig. 1 is the concrete structure schematic diagram that a kind of rotation bolt of steering column of the utility model is done over again with tooling.
In figure：1- threaded rods, the rotary shaft cores of 2-, 3- sleeves, 3a- rotating handles, 4- sleeve pedestals.
Specific implementation mode
It does over again to a kind of rotation bolt of steering column of the utility model and is made of tooling with reference to the accompanying drawings and examples
Further description.
Embodiment
A kind of rotation bolt of steering column is done over again with tooling, including sleeve 1, and steering column, set are inserted into one end of sleeve
The other end of cylinder then offers a sleeve pedestal 2, and the diameter of sleeve pedestal is more than the internal diameter of steering column, the sleeve pedestal conduct
Opening of one step-shaped top in steering column；
Sleeve 1 is provided with a rotary type mandrel 3 inside it, and one end of the rotary type mandrel is turned to from sleeve insertion
The opening of one end of tubing string is stretched out, and is connected with a threaded rod 4, the just right rotation bolt to be done over again of the threaded rod；
One end of the close sleeve pedestal 2 of rotary type mandrel 3 is provided with rotating handles 3a, and rotary type mandrel and set
Cylinder pedestal is fixed connection.
Threaded rod 4 is screwed in the screw thread of rotation bolt to be done over again by rotary type mandrel 3 by rotating its rotating handles 3a
Hole, and as threaded rod is transferred to going deep into for threaded hole by rotary type mandrel, since rotary type mandrel and sleeve pedestal are solid
Fixed pattern connects, and sleeve pedestal withstands steering column and generates reaction force, and rotation bolt is extracted.
A kind of rotation bolt of steering column of the utility model is done over again with tooling, simple in structure, and service efficiency is high, makes
With impact force is not generated in the process, tubing string hidden danger of quality can be effectively eliminated, improves turning machine final product quality.
