Description

Technical Field

[0001] This utility model relates to a positioning mechanism for spring shot blasting, belonging to the field of spring processing technology. Background Technology

[0002] In the automotive industry, brake axle return springs require shot blasting to improve fatigue strength, corrosion resistance, and remove surface defects (rust, oxide layer, and burrs). However, shot blasting cannot be performed internally on the springs; they must be stretched to a certain length to ensure thorough treatment.

[0003] Chinese utility model patent CN215357999U discloses a "positioning mechanism for high-power shot blasting of springs," comprising two opposing annular mounting seats connected by multiple connecting rods evenly distributed on the circumference of the annulus. Through-hole mounting holes are spaced apart on the circumference between the connecting rods. The mounting holes on both sides of the mounting seats are symmetrically arranged. Nuts are fixed to the mounting seats on both sides of the mounting holes. The internal threads of each nut have the same direction of rotation. A screw rod extending from both ends is connected to the threaded hole of the nut. The inner end of the screw rod has a hook-fitting part adapted to the spring hook, and the outer end has a force-applying part for adjusting the extension and retraction of the screw rod. This utility model structure can connect multiple springs at once through the annular mounting seats. The screw rods on both sides open the springs, thereby achieving all-around shot blasting of the springs. Furthermore, the spacing can be adjusted by the screw rods, making it suitable for processing different types of springs and possessing versatility.

[0004] However, in the aforementioned patent, adjusting the opening of each spring requires sequentially adjusting the gap between the screws at both ends of each spring to stretch and open the spring, making the installation and opening of the springs cumbersome and time-consuming.
