Description

Spring shot blasting clamping device Technical Field The invention belongs to the technical field of spring shot peening, and particularly relates to a spring shot peening clamping device. Background In order to meet the load stiffness requirement and to compensate the power problem generated by the increase of the mass of the whole vehicle, all parts, including the suspension spring, need to be subjected to weight reduction, so that the maximum working stress and the working stress of the spring are greatly increased, and great requirements are put on the manufacture of the spring. At present, the steel wire material strength of the spring is at a higher level, the increase of the material strength can obviously increase the cost of parts, which is contrary to the trend of industry cost reduction and efficiency improvement required by the whole market condition at present, so that the spring fatigue is reinforced on the basis of the prior art in a common mode of reinforcing the residual stress of the surface of the spring is a shot blasting process, and the most effective mode is fine blasting and stress shot blasting. The diameter of the small compression spring steel wire is phi 3, the whole shot blasting surface strengthening is required after coiling, the shot blasting strength is 0.25A-0.3A, because the operation process is to fix only one end of the spring, the shot blasting is alternately carried out on the two ends, two phenomena are easy to occur on the two end faces of the spring after shot blasting, namely, the phenomenon of outer edge convex edge can occur after shot blasting, the perpendicularity and normal use of the spring are affected, and the spring cannot be repaired after shot blasting. Secondly, the end-to-end ring opening phenomenon of the spring occurs after shot blasting, the spring elasticity and the size are affected, the spring cannot be repaired, and the part machining qualification rate is extremely low. In order to avoid the phenomenon, the method for realizing the fractional shot blasting is realized by manufacturing the special clamping device for the spring shot blasting, the special clamping device protrudes the clamping function of fixing the upper end face and the lower end face of the spring, the inner surface and the outer surface of the spring are subjected to shot blasting firstly, and then the end face of the spring is subjected to shot blasting. Disclosure of Invention Aiming at the defects of the prior art, the technical scheme adopted by the invention for solving the technical problems is that the spring shot blasting clamping device comprises a bottom supporting mechanism, a spring shot blasting clamping device and a spring shot blasting clamping device, wherein screw piles are symmetrically arranged in the bottom supporting mechanism; The spring to be processed is arranged at the top of the bottom supporting mechanism; The adjusting mechanism is arranged at the top of the stud; The long nut is arranged at the top of the stud, and the adjusting mechanism is fixed on the stud; The adjusting mechanism includes: The pressing plate is arranged at the top of the stud, a groove is formed in the bottom of the pressing plate, and a mounting hole is formed in the middle of the pressing plate; The folding assemblies are symmetrically arranged on two sides of the mounting hole and are mounted on the top of the pressing plate; and the clamping component is arranged at the bottom of the folding component. Further, the adjusting mechanism further includes: The telescopic rods are uniformly arranged at the top of the inner wall of the groove, are arranged around the mounting holes and are used for adjusting the height of the upper supporting ring and are suitable for springs to be processed with different lengths; The upper supporting ring is arranged at the bottom of the telescopic rod and is made of rubber, so that the top of the spring to be processed can be contacted with the upper supporting ring, friction force is increased, and scratches are reduced; the inner wall of the lantern ring is in sliding connection with the outer wall of the upper supporting ring, the downward moving length of the lantern ring is determined according to the circle combining positions of different springs to be processed, the circle combining positions are shielded, the end face of the springs to be processed is protected when shot blasting is carried out on the inner surface and the outer surface of the springs, the end face of the springs to be processed is directly physically isolated, the shot blasting only strengthens the inner surface and the outer surface, and the edge convex edge phenomenon of the end face is effectively avoided. Further, the bottom support mechanism includes: The ring groove, the base is installed at the top of ring groove, the inner wall of base cup joints mutually with the outer wall of stud, the bar hole has been seted up to the outer wall symmetry of ring groove, o
