Description

Technical Field

[0001] The utility model relates to the technical field of spring detection, and particularly relates to a strong pressure head recognition mechanism for a suspension spring. Background Art

[0002] For the spring head recognition mechanism of a suspension spring strong pressure automatic line, the failure rate is high, scratches are prone to appear on the end coils, and products with too large a bending degree cannot be used; the main reason is the defect of the congenital structure. It is necessary for the head recognition seat rings at both ends to extend into the spring end coils, and the spring is driven to rotate by rotating the seat rings to achieve the set torque of the rotating motor to complete the orientation; in order to facilitate the head recognition process of the spring end, a head recognition mechanism is required.

[0003] For the current traditional head recognition mechanism, when the spring comes out of the tempering furnace and shot blasting machine, the bending direction of the spring randomly appears at any position of 360 degrees. The end coil of the spring with a large eccentricity deviates from the left and right center lines of the head recognition seat ring, which makes the head recognition seat ring unable to extend into the spring end coil, resulting in situations such as unsuccessful orientation, spring extrusion deformation, and damage to the equipment tooling. Moreover, a special head recognition seat ring needs to be designed for each type of spring. Due to the rotational static friction, the head recognition seat ring wears seriously, and scratches are also prone to appear on the surface of the spring end coil. After the seat ring wears to a certain extent, a new seat ring must be replaced. Summary of the Utility Model

[0004] The embodiment of the present disclosure relates to a strong pressure head recognition mechanism for a suspension spring. This mechanism uses two roller bars to rotate and drive the spring to rotate, uses a laser infrared probe to detect the position of the spring end, controls the roller bars to stop rotating to complete the head recognition, and through the roller bars contacting the outer ring of the spring, the static friction is changed to rolling friction. The orientation is in place through non-contact detection by the infrared probe, and the orientation can be completed without reaching the originally designed torque. The reduced friction will not cause scratches on the spring surface. At the same time, the roller bars rotate by rubbing against the outer circle of the spring, and there is no need to use an orientation seat ring, thus avoiding the problem that the orientation seat ring cannot extend into the spring end coil due to too large a bending degree of the spring and the center deviation of the two end coils from the center of the orientation seat. Any eccentric spring with any bending degree can achieve automatic orientation.
