New energy automobile torsion bar spring suspension surface laser thermal treatment device

Abstract

The invention discloses a new energy automobile torsion bar spring suspension surface laser thermal treatment device. The device comprises a reaction frame. A reaction chamber is formed in the reaction frame. The reaction chamber upwards communicates with the outside world. A clamping chamber and a constant pressure chamber are formed in the front end and the rear end of the reaction chamber respectively, and both the clamping chamber and the constant pressure chamber communicate with the reaction chamber. Two positioning plates are welded to the top of the reaction frame. One clamping grooveis formed in the end, close to the other positioning plate, of each positioning plate. The new energy automobile torsion bar spring suspension surface laser thermal treatment device has the advantagesthat because a movable baffle and a driven gear part structure are arranged, excellent centering clamping on a torsion bar is achieved; and when the torsion bar moves in the reaction chamber, a micromotor can be started to be used for driving a driving gear to rotate, the driving gear can drive a driven gear meshed with the driving gear rotate in the rotating process, the driven gear rotates todrive an inner round sleeve to rotate, a clamping jaw and the torsion bar are driven by the inner round sleeve to rotate, and it is guaranteed that lasers on a laser slab can evenly light on the torsion bar.

Description

technical field [0001] The invention relates to the technical field of suspension processing, in particular to a laser heat treatment device for the surface of a torsion bar spring suspension of a new energy vehicle. Background technique [0002] The torsion bar spring suspension is a rod-shaped spring that uses the torsional deformation of a rod (or rod, bar) to produce a spring effect. It is characterized by a rod-shaped spring that produces a spring effect per unit volume. It is characterized by a large average energy storage per unit volume. The structure is simple in shape and light in weight. It is generally used as a vehicle suspension spring and a stabilizing device, and sometimes it is also used as a valve spring for high-speed rotating machinery. The section of torsion bar spring suspension material usually has three types: round bar, hollow bar and rectangular cross-section strip. The most commonly used is torsion bar spring suspension made of round bar; the exist...
