Abstract
The invention discloses a kind of method and device preventing plate spring seat for automobile isothermal hardening from deforming, first make positioning seat, arrange through hole on positioning seat, the size and location of through hole are identical with the installing hole on plate spring seat for automobile；Secondly before isothermal hardening, by bolt-through through hole and screw with installing hole, positioning seat is made to be assembled together closely with plate spring seat for automobile, then positioning seat is carried out together with plate spring seat for automobile isothermal quenching technique process, after isothermal hardening terminates, after being initially cooled to room temperature, then remove bolt, take out plate spring seat for automobile and carry out lower sequence processing again.The present invention limits the deformation of plate spring seat for automobile by positioning seat, effectively solves the problem on deformation of autobody sheet spring abutment isothermal quenching technique process, meets the product quality requirement of client.
Description
Technical field:
The present invention relates to a kind of plate spring seat for automobile isothermal hardening technology, particularly relate to one and prevent plate spring seat for automobile isothermal hardening
The method and device of deformation.
Background technology:
The spring block of current high-end heavy truck automobile begins with ADI material.Production technology is cast blank--machinery roughing--
Isothermal hardening--polish.And isothermal quenching technique process typically can cause the deformation of plate spring seat for automobile, through measuring and analyzing vapour
After sweep spring abutment isothermal hardening, the situation of deformation, the mainly dimension overproof of spring block installing hole centre-to-centre spacing, cause product time serious
Product are defective.
Summary of the invention:
The technical problem to be solved is: overcome the deficiencies in the prior art, it is provided that a kind of novel in design, simple to operate,
It is swift in motion and the method and device preventing plate spring seat for automobile isothermal hardening from deforming that anti-deformation is effective.
The technical scheme is that
It is the duplication of claim herein, after claim determines, then replicates in this place.
The invention has the beneficial effects as follows:
1, the present invention is before isothermal hardening, and bolt is assembled together through positioning seat closely with plate spring seat for automobile, carries out isothermal
Quenching technical process, isothermal hardening terminates, and after being cooled to room temperature, removes bolt, takes out plate spring seat for automobile and carries out lower sequence processing again,
Effectively solve the problem on deformation of autobody sheet spring abutment isothermal quenching technique process, meet the product quality requirement of client.
2, the present invention makes positioning seat and plate spring seat for automobile fasten by bolt, reduces the deflection of plate spring seat for automobile, and
Easy accessibility, efficiency is high.
3, the present invention is novel in design, simple to operate, be swift in motion and anti-deformation is effective, and it is applied widely, it is easy to push away
Wide enforcement, economic benefit is obvious.
Accompanying drawing illustrates:
Fig. 1 is the structural representation of the device preventing plate spring seat for automobile isothermal hardening from deforming；
Fig. 2 is the upward view of the device preventing plate spring seat for automobile isothermal hardening from deforming shown in Fig. 1.
Detailed description of the invention:
Embodiment: see Fig. 1 and Fig. 2, in figure, 1-positioning seat, 2-bolt, 3-plate spring seat for automobile.
Preventing the method and device that plate spring seat for automobile isothermal hardening deforms, its technical scheme is:
A, first making positioning seat 1, arrange through hole, in the size and location of through hole and plate spring seat for automobile 3 on positioning seat 1
Installing hole identical；
B, before isothermal hardening, bolt 2 run through through hole and screw with installing hole, making positioning seat 1 tight with plate spring seat for automobile 3
Be assembled together, then positioning seat 1 is carried out together with plate spring seat for automobile 3 isothermal quenching technique process, isothermal hardening terminates
After, after being initially cooled to room temperature, then remove bolt 2, take out plate spring seat for automobile 3 and carry out lower sequence processing again.
Between through hole, centre-to-centre spacing uses the intermediate value of plate spring seat for automobile 3 the corresponding mounting hole installing hole size.Bolt 4 has four
Individual and rectangularity is arranged, and is respectively positioned on rectangular four summits.
The above, be only presently preferred embodiments of the present invention, and the present invention not makees any pro forma restriction, all
It is based on any simple modification, equivalent variations and modification that above example is made by the technical spirit of the present invention, all still falls within
In the range of technical solution of the present invention.
