DETAILED DESCRIPTION

[0020] See also Figures 1 to 4In the embodiment of the utility model, the self-aligning round steel cone head turning tool comprises a tool holder 1 and a tool 5. The tool holder 1 is provided with an assembly hole 2 for installation, and a movable groove 6 is provided inside the tool holder 1. The tool 5 is assembled on a movable blade body 3. The movable blade body 3 is adjusted in the movable groove 6. The tool holder 1 is provided with a limit bolt 4 for limiting the forward and backward movement of the movable blade body 3. When the end face of the round steel enters the cutting edge of the tool 5 with a certain taper, the end face of the round steel will push the movable blade body 3 to move and automatically find the center for turning. The tool holder 1 and the movable blade body 3 have free movement. There is a certain gap for movement, and free movement is limited to the X / Y coordinates. Under the fixation of the limit bolt 4, the Z coordinate movement direction of the movable blade body 3 is limited to fix it in the movable groove 6. The movable blade body 3 and the tool 5 are both replaceable parts, which are replaced according to the size of the processed round steel. There is a gap between the movable groove 6 and the movable blade body 3, and the gap distance is the movable tolerance of the movable blade body 3. During the processing, the automatic movable tolerance is used to make it unnecessary to align the tool, saving the tool aligning process, and processing is carried out within the error range of the workpiece clamping, thereby improving the efficiency of batch processing.

[0021] In a preferred embodiment, the back of the movable blade body 3 is installed with an intermediate clamp 10 via a transverse sliding connection 8, and the back of the intermediate clamp 10 is installed with a fixed clamp 11 via a longitudinal sliding connection 9. Through the sliding connection structure, the position of the movable blade body 3 is maintained without tilting, and the cutter head and the workpiece are kept at a cutting angle. The coordination of transverse sliding and longitudinal sliding enables the movable blade body 3 to achieve free movement of the X / Y coordinates.

[0022] In a preferred embodiment, the structure of the transverse sliding connector 8 is the same as that of the longitudinal sliding connector 9. The transverse sliding connector 8 is composed of a slide groove and a slider. The slide groove is opened on the connected structure, and the slider is set on the middle clamp plate 10, so that the middle clamp plate 10 and the movable blade body 3 can slide. The sliding structure of the slide groove and the slider is only a sliding installation method. The sliding connection method of the slide groove and the slider is low in cost. Adding lubricant to reduce the friction between them can improve the smoothness of sliding and reduce wear to extend its service life.

[0023] In a preferred embodiment, at least two movable positioning holes 12 are provided on the movable blade body 3, the middle clamp plate 10 and the fixed clamp plate 11, and a detachable movable positioning bolt 7 is installed in the movable positioning hole 12. The movable blade body 3 has two operation modes, one is a free movable turning mode, and the other is to fix the movable blade body 3, the middle clamp plate 10 and the fixed clamp plate 11 to each other through the movable positioning bolt 7 so that they no longer move, thereby improving the processing accuracy and being suitable for different processing requirements.

[0024] In a preferred embodiment, half of the movable positioning bolt 7 is provided with a thread and the other half is a pin. The threaded portion is threadedly connected to the movable blade body 3, and the pin portion passes through the middle clamp plate 10 and the fixed clamp plate 11. The pin end of the movable positioning bolt 7 can be set to be conical, which provides convenience during the calibration and positioning process. The design of half thread and half pin can avoid the problem of the inability or difficulty of entering the holes when the thread enters the middle clamp plate 10 and the fixed clamp plate 11.

[0025] In a preferred embodiment, half of the limiting bolt 4 is provided with a thread and the other half is a pin. The threaded portion is threadedly connected to the tool holder 1. A pin hole is provided on the fixed clamping plate 11. The pin portion extends into the pin hole to limit the fixed clamping plate 11. The number of the limiting bolts 4 is at least two, and the fixed clamping plate 11 is not movable, so the limiting bolts 4 are required to fix the fixed clamping plate 11.

[0026] It should be noted that the above embodiments all belong to the same utility model concept, and the description of each embodiment has its own focus. For matters that are not described in detail in some embodiments, reference can be made to the description in other embodiments.

[0027] The above-mentioned embodiments only express the implementation methods of the utility model, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, and these all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
