Embodiment
[0012] Example: see figure 1 and figure 2 , in the figure, 1-positioning seat, 2-bolt, 3-automobile leaf spring seat.
[0013] The method and device for preventing the austempering deformation of the automobile leaf spring seat, the technical proposal of which is:
[0014] a, at first make positioning seat 1, set through hole on positioning seat 1, the size and the position of through hole are identical with the installation hole on the automobile leaf spring seat 3;
[0015] b. Before the isothermal quenching, screw the bolt 2 through the through hole and the installation hole, so that the positioning seat 1 and the automobile leaf spring seat 3 are tightly assembled together, and then the positioning seat 1 and the automobile leaf spring seat 3 are subjected to isothermal In the quenching process, after the isothermal quenching is completed, it is first cooled to room temperature, and then the bolt 2 is removed, and the automobile leaf spring seat 3 is taken out for subse...

The invention discloses a method and a device for preventing the isothermal quenching deformation of an automobile plate spring seat. First, a locating seat is manufactured, through holes are formed in the locating seat, and the sizes and positions of the through holes are identical to those of mounting holes in the automobile plate spring seat. Then, before isothermal quenching, bolts penetrate through the through holes and are connected in the mounting holes in a screwing manner, the locating seat is tightly assembled with the automobile plate spring seat, and then, an isothermal quenching technical process is simultaneously carried out on the locating seat and the automobile plate spring seat. After isothermal quenching is finished, first, the locating seat and the automobile plate spring seat are cooled to a room temperature, then, the bolts are removed, and the automobile plate spring seat is taken out for the next procedure of machining. The deformation of the automobile plate spring seat is limited by the locating seat, the deformation problem of the automobile steel plate spring seat in the isothermal quenching technical process is effectively solved, and the product quality requirement of a customer is met.
Description
Technical field: [0001] The invention relates to an automobile leaf spring seat isothermal quenching technology, in particular to a method and a device for preventing the automobile leaf spring seat from isothermal quenching deformation. Background technique: [0002] At present, the leaf spring seats of high-end heavy-duty trucks begin to use ADI materials. The production process is casting blank--mechanical rough machining--isothermal quenching--finishing. The isothermal quenching process generally causes the deformation of the automobile leaf spring seat. After measuring and analyzing the deformation of the automobile leaf spring seat after isothermal quenching, the main reason is that the center distance of the leaf spring seat installation hole is out of tolerance, and in severe cases, the product is unqualified. . Invention content: [0003] The technical problem to be solved by the present invention is to overcome the deficiencies of the prior art and provide a no...
