Description
Technical field:
The present invention relates to Machining Technology field, relate to a kind of steering screw anti-percolator particularly.
Background technology:
Motor vehicle bears larger surging force under steam, so some Axle Parts of motor vehicle adopt 20CrMnTi carburizing and quenching to obtain good mechanical property usually, in order to improve the surface abrasion resistance, fatigue strength, heart portion obdurability etc. of motor vehicle Axle Parts, usual employing carburizing and quenching, and screw thread and splined section control hardness again, guaranteeing can not more than 38HRC, to ensure the toughness of screw thread, avoids breaking and the fracture at thread place of thread.Steering screw is a key part in automobile steering system, and the quality of its quality product directly decides motor turning reliability and security.
Be typically employed in screw thread place and be coated with after permeability-reducing admixture in order to control thread hardness and anneal at thread segment intermediate frequency after carburizing and quenching or carburizing and quenching in prior art.Adopt carburizing and quenching after screw thread place is coated with permeability-reducing admixture, add labor capacity, and permeability-reducing admixture belongs to fluidity material, the deviation in antiseepage region may be occurred, the consistence of product can not be realized, and product appearance has obvious antiseepage vestige; Medium frequency quenching after employing carburizing and quenching, adds operation equally, also needs to drop into intermediate frequency equipment, all high to the requirement of equipment and personnel, and intermediate frequency annealing wastes the energy again.Namely in prior art for the anti-percolator complex structure of motor turning screw rod, batch production expends time in, energy consumption is large.
Summary of the invention:
For this reason, technical problem to be solved by this invention is the anti-percolator complex structure for motor turning screw rod in prior art, and batch production expends time in, and energy consumption is large, thus proposes a kind of steering screw anti-percolator.
For solving the problems of the technologies described above, technical scheme of the present invention is as follows:
A kind of steering screw anti-percolator, comprising:
Antiseepage body, described antiseepage body fits tightly the first end outside surface at workpiece;
Bolt, described bolt is arranged on the second end side surface of described workpiece;
Nut, described nut is arranged on the first end side of described workpiece;
Packing ring, described packing ring is arranged between described nut and described antiseepage body.
Preferred as technique scheme, described antiseepage body is right cylinder.
Preferred as technique scheme, one end of described antiseepage body is provided with the first through hole, and the diameter of described first through hole is identical with the screw diameter of described bolt.
Preferred as technique scheme, described antiseepage body is made up of high-temperature resistance plastice.
Preferred as technique scheme, the axial centre of described workpiece is provided with threaded hole, and described bolt is fitted tightly by described threaded hole and described workpiece.
Preferred as technique scheme, the centre of described packing ring is provided with the second through hole, and the diameter of described second through hole is identical with the screw diameter of described bolt.
Beneficial effect of the present invention is: it can protect antiseepage position effectively when quenching, and structure is simple, easy for installation, with low cost, can produce in batches, have good practicality and economy.In addition, antiseepage body of the present invention is made up of high-temperature resistance plastice.Antiseepage part can be reused, saved resource, reduce further production cost.
Accompanying drawing illustrates:
The following drawings is only intended to schematically illustrate the present invention and explain, not delimit the scope of the invention.Wherein:
Fig. 1 is a kind of steering screw anti-percolator schematic diagram of the present invention.
Nomenclature in figure:
1 – antiseepage body, 2 – workpiece, 3 – bolts, 4 – nuts, 5 – packing rings, 6 – antiseepage positions.
Embodiment:
As shown in Figure 1, a kind of steering screw anti-percolator of the present invention, comprising:
Antiseepage body 1, described antiseepage body 1 is right cylinder, and described antiseepage body 1 is the middle right cylinder having through hole, and described antiseepage body 1 fits tightly on the first end outside surface of workpiece 2.The cylinder length of described antiseepage body 1 can need the antiseepage position of protection to design according to reality when quenching.In the present embodiment, workpiece 2 is steering screw, and steering screw is a key part in automobile steering system, and the quality of its quality product directly decides motor turning reliability and security.Draw bore is joined after the first end of steering screw and the tail end of steering screw require quenching; antiseepage position 6 needs antiseepage when whole Component quench; the cylinder length choosing antiseepage body 1 can fully closely entangle antiseepage position 6, and antiseepage position 6 can be protected when quenching.
Described antiseepage body 1 is made up of high-temperature resistance plastice, and described antiseepage body 1 adopts material that is high temperature resistant, that do not peel that antiseepage part can be made can to reuse when quenching, and has saved resource, has reduced production cost.
Bolt 3, described bolt 3 is locking thru-bolt.Described bolt 3 is arranged on the second end side surface of described workpiece 2, namely bolt 3 is arranged on the second end side surface of described workpiece 2 with one end of head, the axial center portion of described workpiece 2 is provided with threaded hole, the diameter of described threaded hole is identical with the screw diameter of described bolt 3, the spiro rod length of described bolt 3 is greater than the length of described workpiece 2, and described bolt 3 is fitted tightly by described threaded hole and described workpiece 2.
