Embodiment Construction

[0040] Below in conjunction with the drawings, preferred embodiments of the present invention are given and described in detail.

[0041] It should be noted that the "upper" and "lower" in the present invention refer to figure 1 as the base direction.

[0042] Such as figure 1 As shown, the embodiment of the present invention provides a stable output gap-adjustable ultrasonic rolling device, which includes a hollow inner pressure cap 3 connected in sequence along the axial direction, an adjustment ring 10, a fixed cover 11 and a sliding sleeve 6 and The tool seat 7 is sheathed on the outside of the sliding sleeve 6 , and the sliding sleeve 6 is slidably matched with the tool seat 7 so that the sliding sleeve 6 slides inside the tool seat 7 . The inner cavities of the pressure cap 3, the fixed cover 11 and the sliding sleeve 6 communicate with each other and form an installation room, in which the balls 1, the top cap 2, the horn 4 and the changer are arranged sequentially fr...

Abstract

The invention relates to a gap-adjustable ultrasonic rolling device capable of stably outputting. The gap-adjustable ultrasonic rolling device capable of stably outputting comprises a pressing cap, anadjusting ring, a fixing cover, a sliding sleeve and a tool seat, wherein the pressing cap, the adjusting ring, the fixing cover and the sliding sleeve are hollow and sequentially connected in the axial direction, the tool seat is arranged on the outer side of the sliding sleeve in a sleeving mode, and the sliding sleeve is in sliding fit with the tool seat; inner cavities of the pressing cap, the fixing cover and the sliding sleeve are communicated with each other to form an installation chamber, the installation chamber is internally provided with a ball, a top cap, an amplitude-change lever and a transducer which are sequentially connected, the ball partially extends out of the outer wall of the pressing cap, and the amplitude-change lever is connected with the fixing cover; and the adjusting ring is arranged between the pressing cap and the fixing cover. According to the ultrasonic rolling device, the adjusting ring is additionally arranged between the pressing cap and the fixingcover, so that the ball clearance is controllable, the amplitude-change lever with a flange is adopted, the flange is arranged at the node position of the amplitude-change lever, the output effect ofthe amplitude-change lever is not influenced, and the amplitude-change lever is fixed at the same time, so that the output of the amplitude-change lever is more stable; and a spring is arranged at thelower end of the device to play a buffering and protecting role.

Description

technical field [0001] The invention relates to the technical field of material strengthening, in particular to an ultrasonic rolling device with adjustable gap and stable output. Background technique [0002] With the continuous development of science and technology, the quality requirements for various mechanical equipment are also continuously improved. Traditional surface strengthening technologies mainly include rolling, shot peening and rolling, etc., but these traditional technologies still have shortcomings, for example, traditional rolling is easy to cause scratches on the surface of parts. Shot peening has limited impact kinetic energy, is inefficient, and increases the surface roughness of the part. The ultrasonic rolling technology adds ultrasonic vibration on the basis of traditional rolling, which can not only effectively reduce the surface roughness, but also refine the surface grains of the workpiece and improve the wear resistance and fatigue resistance of ...
