AI Technical Summary
Technical Problem
Existing blackening treatment tooling cannot effectively solve the problem of uneven blackening inside blind holes of automotive piston parts, resulting in a high product defect rate.
Method used
Design a clamping column with a pointed tip, and a tooling with the clamping column axes coinciding and able to slide relative to each other. Adjust the spacing of the clamping units through a sliding connection component to promote the flow and uniform coverage of the blackening liquid in the blind hole.
Benefits of technology
This ensures a uniform blackening effect in blind hole areas, solving the problems of insufficient contact of the blackening liquid and uneven blackening content caused by the sealing of blind holes in traditional tooling, thus improving product quality.

Abstract
The utility model discloses a kind of for blackening treatment of automobile piston parts tool, by being provided with the clamping column with sharp head, using its axis coincides and the characteristics of relatively slidable, it can be accurately inserted into the blind hole of automobile piston parts of clamping column, when adjacent clamping unit spacing is adjusted, sliding connection component can drive clamping column to move in blind hole moderately, promote the flow and uniform coverage of blackening liquid in blind hole, sharp head structure is more consistent with blind hole bottom, ensure that blind hole portion obtains suitable blackening effect;The distance between every two adjacent clamping columns on the same clamping unit is consistent with the design, so that clamping column forms uniform support and positioning layout when clamping automobile piston parts, uniform spacing provides regular channel for the flow of blackening liquid between adjacent clamping columns, promote liquid uniform penetration to part surface and blind hole area, ensure that the moving path of clamping column in blind hole is more stable, drive blackening liquid uniform coverage blind hole inner wall.
