Description
Technical Field
The utility model relates to a stress relief device belongs to vibratory stress relief device technical field.
Background
The vibration ageing treatment is a method for eliminating the internal residual stress of engineering materials, and the essence of the vibration ageing is that a dynamic stress is applied to a workpiece in a vibration mode, when the dynamic stress is superposed with the residual stress of the workpiece and reaches or exceeds the microscopic yield limit of the materials, the workpiece can generate microscopic or macroscopic local and integral elastic plastic deformation, and simultaneously, the residual stress in the workpiece is reduced and homogenized, and finally, the purposes of preventing the deformation and cracking of the workpiece and stabilizing the size and geometric accuracy of the workpiece are achieved.
Most of the prior vibration aging methods are to mount a motor system (called an exciter) having an eccentric weight on a member, support the member by an elastic body such as a rubber pad, and start the motor and adjust the rotation speed of the motor by a controller so that the member is in a resonance state. But has certain limitation or unsatisfactory aging effect on small and medium-sized workpieces.

Detailed Description
The present invention will be further described, but not limited to, by the following examples in conjunction with the accompanying drawings.
Example 1:
as shown in fig. 1 to 2, the present embodiment provides a stress relief apparatus, which includes a base 2, a crankshaft 5, a vibration table 4, and a motor 1; shaking table 4 sets up in base 2 top, and motor 1 sets up in base 2 bottom, and motor 1 passes through bent axle 5 and connects shaking table 4. Four springs 3 are arranged between the vibration table 4 and the base 2.
Wherein, base 2 is the rectangle and center department has seted up the through-hole, and motor 1 passes through bolt fixed mounting and puts at the central point of base 2 bottom, and the output shaft of motor 1 passes the through-hole.
The shaking table 4 is rectangular, nine parallel T-shaped grooves 41 are formed in the upper surface of the shaking table 4, a groove is formed in the center of the bottom of the shaking table 4, and a bearing 6 is installed in the groove.
The top end of the crankshaft 5 is connected with the vibrating table 4 through a bearing 6, and the bottom end of the crankshaft 5 is connected with the output shaft of the motor through a key 7.
Four 3 equipartitions of spring set up, spring one end and base fixed connection other end and shaking table fixed connection can play the effect of stable support shaking table 4.
The working process is as follows: a workpiece is clamped on a vibrating table, a motor is started to drive a crankshaft to rotate, and the other rotating shaft of the crankshaft rotates around a motor shaft, so that the other rotating shaft drives the vibrating table to do circular vibration around the motor shaft, the vibration frequency is the rotating speed of the motor, and the amplitude is the distance between two rotating shafts of the crankshaft.
Example 2:
a stress relief device constructed as described in embodiment 1, except that: the spring is replaced by a balloon.
Example 3:
a stress relief device constructed as described in embodiment 1, except that: the spring is replaced by a silicone body.
Example 4:
a stress relief device constructed as described in embodiment 1, except that: the electric machine is replaced by a hydraulic motor, and the same function is achieved.
Example 5:
a stress relief device constructed as described in embodiment 1, except that: the crankshaft is replaced by an eccentric shaft.
