Abstract

The invention provides an inner arc surface ultrasonic rolling tool head. The inner arc surface ultrasonic rolling tool head comprises an ultrasonic generation device, a rolling tool head, a shank, a swing rod, a connecting shaft, a fastening bolt and a fastening nut. The ultrasonic rolling tool head is mounted on a milling machine main shaft through the shank; the other end of the shank is connected with the swing rod; the ultrasonic generation device is mounted at the lower end of the swing rod; and the rolling tool head is directly controlled to finish the machining process. The spherical surface revolving motion of the rolling tool head in a space in the ultrasonic machining process can be realized by using adjustment of a hinged angle between the shank and the swing rod and rotation of the milling machine main shaft, so that the ultrasonic rolling surface treatment can be performed for an arc inner wall workpiece. An ultrasonic surface treatment device is normally used for machining an outer circular surface, a plane and an end surface; and an ultrasonic machining device controls a composite trajectory of a main shaft revolving trajectory and a tool head swing trajectory to treat inner arc surfaces of workpieces with different revolving radius so as to widen the ultrasonic machining process range.

Description

A kind of inner arc surface ultrasonic burnishing tool heads

Technical field

The present invention relates to a kind of inner arc surface ultrasonic burnishing tool heads, belong to circular arc inner wall surface process field.

Background technology

The surface quality of part is the important component part of machining accuracy, and when usual slewing parts surfaceness requires lower, the general employing mode such as grinding machine or polishing is processed. But some special occasions and high precise equipment, what can the surfaceness of part be limited is more strict, though now adopting the technique such as grinding machine or polishing can reach surfaceness requirement reluctantly, but process-cycle length, cost of investment height, and usually need to use a large amount of cutting fluid, environmental pollution is serious, and efficiency is low and labor strength is big.

By workpiece surface is carried out ultrasonic burnishing processing, it is possible to obtain low roughness and high manufacturing accuracy, this point has application on lathe and milling machine. Ultrasonic surface processing unit (plant) is loaded on lathe, drives horn to rotate by lathe, or with lathe spindle operation, can not process instrument as one separately and independently use. Grinding machine precision work after traditional circular arc inwall processing mode milling machine roughing, this method efficiency is lower and part performance does not have bigger lifting. Ultrasonic burnishing device is directly installed on milling machine or lathe more, and by the restriction of tradition milling machine and lathe main shaft, ultrasonic burnishing device is comparatively applicable to periphery, plane and end face processing.

Summary of the invention

The present invention is directed to the deficiency of existing ultrasonic burnishing processing units, it is provided that a kind of ultrasonic machining device that can process walled workpieces in circular arc.

The object of the present invention completes by following technical solution, and a kind of inner arc surface ultrasonic burnishing tool heads, comprises ultrasonic generator, rolling tools head, handle of a knife, swings bar, coupling shaft, fitting nut, holding bolt, it is characterised in that, handle of a knife is connected by coupling shaft with swing bar, ultrasonic generator is arranged on and swings the lower end of bar, and handle of a knife is arranged on the main shaft of milling machine.

Coupling shaft one end is connected by fitting nut, and the handle of a knife lower end section of having is slotted, and has a through hole, through hole holding bolt connects, swinging and have a screw thread through hole on bar, for installing holding bolt, adjustable ultrasonic generator is at the stroke swung in bar and plays fastening effect.

The inwall of different radii can be carried out ultrasonic machining by changing ultrasonic generator in the swing angle of the position swung in bar and swing bar.

The present invention can process the bigger workpiece of diameter of bore, and work range is big, is easy to process the bigger workpiece of bore depth, and can convenient and simple regulate for different radiuses, expands work range.

The description of symbols of Fig. 1: 1 handle of a knife, 2 fitting nuts, 3 swing bars, 4 ultrasonic generators, 5 rolling tools heads, 6 holding bolts, 7 coupling shafts.

Embodiment

Below in conjunction with accompanying drawing, the present invention doing detailed introduction: as shown in Figure 1, 2, a kind of inner arc surface ultrasonic burnishing tool heads, its structure comprises 1 handle of a knife, 2 fitting nuts, 3 swing bars, 4 ultrasonic generators, 5 rolling tools heads, 6 holding bolts, 7 coupling shafts. 4 ultrasonic generators are arranged in 3 swing bars, and 3 swing bars have screw thread through hole, and available holding bolt is fixed and adjustment stroke. 1 handle of a knife is connected by 7 coupling shafts with 3 swing bars, the 3 swing swingable certain angles of bar, and 6 holding bolts are used for fastening 7 coupling shafts makes it fix.

The working process of the present invention is as follows, and 5 rolling tools heads are arranged on milling machine main shaft by handle of a knife, and the other end of 1 handle of a knife is connected with 3 swing bars, and 4 ultrasonic generators are arranged on the lower end of 3 swing bars, and directly control 5 rolling tools heads complete the course of processing. Utilize the adjustment of 1 handle of a knife and 3 swing bar hinge angles and the rotation of milling machine main shaft, it may be achieved in ultrasonic machining process, 5 rolling tools heads are in space Internal Spherical Surface turning motion, walled workpieces in circular arc can be carried out ultrasonic burnishing surface treatment.

The present invention is not limited to above-described embodiment; on the basis of technical scheme disclosed by the invention; the technician of this area is according to disclosed technology contents; not needing creative skilled labour that some technology features wherein just can be made some to replace and distortion, these are replaced and are out of shape all in protection scope of the present invention.
