[0001] The utility model relates to the technical field of metal parts processing equipment, in particular to a device for eliminating internal stress of metal parts. Background Art

[0002] Internal stress refers to the stress that remains inside an object after the external load is removed. It is caused by uneven volume changes in the macroscopic or microscopic structure of the material. In order to ensure the strength of metal parts, people usually need to eliminate the internal stress of processed metal parts, so special internal stress elimination devices are used.

[0003] Existing metal parts internal stress elimination devices generally directly clamp the metal parts on the device and then vibrate to eliminate the internal stress. For example, a metal internal stress elimination device with a prior patent announcement number of CN220468084U is difficult to adjust because the excitation point of the device is fixed and the effect of eliminating the internal stress of the metal parts depends on the position of the excitation point. As a result, the device's ability to eliminate the internal stress of the metal parts is relatively limited, thereby reducing the device's effect of eliminating the internal stress of the metal parts. For this reason, we provide a metal part internal stress elimination device. Utility Model Content

[0025] The chassis 1 is provided with a placement plate 2 of a circular structure above the chassis 1, and a telescopic rod 3 is fixedly connected circumferentially at an equidistant position near the edge between the placement plate 2 and the chassis 1, and a spring 4 is sleeved on the outside of the telescopic rod 3, and the two ends of the spring 4 are respectively fixedly connected to the chassis 1 and the placement plate 2, and the top center of the chassis 1 is vertically rotated and connected to a rotating shaft 5, and a rotating rod 6 passes through the upper part of the rotating shaft 5 and the rotating rod 6 is rotatably connected to the rotating shaft 5, and eccentric wheels 7 are fixedly sleeved on the outside of both sides of the rotating rod 6, and one end of the rotating rod 6 is coaxially fixedly connected to a motor, and the motor is fixedly connected to the rotating shaft 5 through a bracket;

[0026] The adjusting component includes a gear ring 101 fixedly sleeved on the outside of the rotating shaft 5, a gear disc 102 is rotatably connected to the top of the chassis 1, and the gear disc 102 is meshed with the gear ring 101, a worm wheel 103 is coaxially fixedly connected to the bottom of the gear disc 102, a worm 104 is rotatably connected to the top of the chassis 1, and the worm 104 is meshed with the worm wheel 103, one end of the worm 104 is movably connected to a hand wheel 105, the top of the chassis 1 is slidably connected to a limit rod 106 through a guide frame, one end of the limit rod 106 is fixedly connected to a connecting plate 107, and the lower part of the connecting plate 107 is rotatably connected to the hand wheel 105, a spring 2 108 is sleeved on the outside of one side of the limit rod 106, and the two ends of the spring 2 108 are respectively fixedly connected to the guide frame and the connecting plate 107 Next, limiting holes 109 are equidistantly provided on the outside of the rotating shaft 5, the cross-sectional size of the limiting rod 106 matches the size of the limiting hole 109, the number of the limiting holes 109 is six groups, and the angle between two adjacent groups of limiting holes 109 is 60 degrees. A cavity is provided inside one side of the worm 104 and one end of the handwheel 105 extends into the cavity, one end of the handwheel 105 is fixedly connected to the limiting plate 110, and the outside of the handwheel 105 is equidistantly fixedly connected to the limiting strip 111, and a limiting groove is provided at the movable connection between the worm 104 and the handwheel 105 corresponding to the position of the limiting strip 111 and is slidably connected to the limiting strip 111, which can not only enable the handwheel 105 to extend and contract, but also ensure the normal transmission between the handwheel 105 and the worm 104.

[0027] The implementation principle of a metal part internal stress elimination device in the embodiment of the present application is as follows: first, the metal part is placed on the top of the placement plate 2, and then the motor is started. The motor drives the rotating rod 6 to rotate, so that the two sets of eccentric wheels 7 can be driven to rotate together. The rotation of the eccentric wheel 7 can regularly push the placement plate 2, and under the cooperation between the telescopic rod 3 and the spring 1 4, the placement plate 2 can be vertically vibrated, thereby driving the metal part to vibrate to eliminate the internal stress inside it. When it is necessary to change the position of the device for the metal part excitation point, the sliding cooperation between the limit bar 111 and the limit groove is used to pull the hand wheel 105 outward, and in the process of pulling the hand wheel 105, the limit rod 106 will also be driven to move together. At this time, the limit rod 106 will disengage from the limit hole 109 and stretch the spring 108. Then, the hand wheel 105 is rotated to utilize the limiting effect between the limit bar 111 and the limit groove, so that the worm 104 can be driven to rotate. The worm 10 The rotation of the worm wheel 103 will drive the worm wheel 103 meshing with it to rotate, and the rotation of the worm wheel 103 will drive the toothed disc 102 to rotate. The meshing action between the toothed disc 102 and the gear ring 101 can drive the rotating shaft 5 to rotate, and the rotation of the rotating shaft 5 drives the rotating rod 6 to rotate, thereby driving the eccentric wheel 7 to make a circular motion, thereby realizing the change of the exciting point of the device and ensuring the effect of removing the internal stress of the metal part. When the limiting rod 106 is aligned with the next limiting hole 109, the hand wheel 105 is released, and the limiting rod 106 is reinserted into the limiting hole 109 by the rebound effect of the spring 108. At this time, the hand wheel 105 will also automatically reset, thereby realizing the change of the fixed angle of the exciting point, and further ensuring the thoroughness of the removal of the internal stress of the metal part. The self-locking property between the worm 104 and the worm wheel 103 can ensure the stability of the exciting point position after adjustment. Finally, the metal part can be removed after the internal stress is eliminated. Example

[0028] Based on Example 1, this embodiment is further improved in that: the top of the placement plate 2 is fixedly connected with a cylinder 8 at equal intervals in the circumferential direction, and the telescopic end of the cylinder 8 is fixedly connected with a clamping plate 9. The clamping plate 9 is pushed by the cylinder 8 to approach the metal part and make it contact with the metal part, so that the metal part can be clamped, thereby ensuring the stability of the metal part when the device vibrates.
