Embodiment Construction
[0017] Such as figure 1 with figure 2 As shown, a new type of device for turning an inner spherical surface includes a supporting shaft 1, a driven shaft 2, a driving shaft 3, a turning tool 4 and a driving mechanism. The drive shaft 3 and the driven shaft 2 have the same structure and are parallel to each other and are all perpendicular to the support shaft 1. The left part of the support shaft 1 is provided with a mounting groove 5, and the connecting end of the tool bar of the turning tool 4 is vertically fixedly connected with the driven shaft 2. The turning tool 4 is the prior art, which is composed of a tool bar and a blade, and its specific structure will not be described too much. The turning tool 4 is detachably connected to the driven shaft 2, and different diameters can be processed by replacing the turning tool 4 of different lengths. Deep hole 6, the connecting end of turning tool 4 cutter bar is positioned at installation groove 5, and the blade portion of turn...

A novel device for turning an inner spherical surface comprises a supporting shaft, a driven shaft, a driving shaft, a turning tool and a drive mechanism. The driven shaft is arranged on the left portion of the supporting shaft and is connected with the supporting shaft in a rotating manner. An installation groove is formed in the left portion of the supporting shaft. The connection end of a cutter bar of the turning tool is perpendicularly and fixedly connected with the driven shaft. The connection end of the cutter bar of the turning tool is located in the installation groove. The blade part of the turning tool is arranged at the free end of the cutter bar. The distance between the blade part of the turning tool and the axis of the driven shaft is larger than the radius of a to-be-machined deep hole. When the blade part of the turning tool rotates to the left limitation, the cutter bar of the turning tool is parallel to the supporting shaft, and the blade part of the turning tool is located on the exterior of the supporting shaft. When the blade part of the turning tool is rotated to the right limitation from the left limitation, the rotation angle of the blade part is larger than 90 degrees, and when the blade part of the turning tool rotates by 90 degrees in at least one of the clockwise direction or the anticlockwise direction from the left limitation position, the blade part of the turning tool is located on the exterior of the supporting shaft.
Description
technical field [0001] The invention relates to a cutting tool, in particular to an inner spherical cutting device for a small deep hole. Background technique [0002] Under the current manufacturing technology, the turning of the spherical surface is mainly completed by the lathe turning tool, and the hemispherical surface or part of the spherical surface can be completed independently by the lathe, and the larger-sized inner spherical surface, whose shape is close to the complete spherical surface, can also be easily cut out . However, for the small deep hole with a size of about 10 cm and the inner spherical surface in the deep hole, the cutting technology is relatively difficult, and the cost of the related cutting device is relatively high. Contents of the invention [0003] Aiming at the defects in the prior art, the object of the present invention is to provide a novel device for turning inner spherical surfaces, which can cut inner spherical surfaces in small deep...
