Description

TECHNICAL FIELD

[0001] The utility model relates to tool technical field, concretely relates to a lathe fixing device of adjustable. BACKGROUND

[0002] In the maintenance process of large motor, often need to turn some parts, therefore commonly use lathe to process. But due to the large size of large motor, and the size difference is very big, this kind of main shaft generally length exceeds 5m, and the weight exceeds 10t, for this, the conventional lathe is difficult to bear and adapt to part of the rotor and main shaft of large motor, for this, the repair factory generally will be for the parts to be repaired temporarily build a kind of lathe structure to process these parts.

[0003] The lathe commonly used at present has been fixedly installed on the specific position of factory area, for this, the lathe has been taught, and can guarantee its installation level and precision. And the tool holder is generally used on the lathe to fix the tool, due to the base of the lathe has been adjusted horizontally, for this, the precision of the tool holder can be guaranteed. The temporarily built lathe structure generally includes support structure, driving mechanism and tool fixing structure, the support structure, driving mechanism and tool fixing structure are fixed on the hardened ground, so as to replace the base of traditional lathe with hardened ground, so that the flexibility of the whole processing structure is strong, and the adaptability is high, which can adapt to the main shaft and rotor structure of large motor. The support structure can not only support the parts, but also ensure the rotation of the parts relative to the support structure. The driving mechanism is used to drive the rotation of the parts, and the tool fixing structure is generally a conventional tool holder structure. In the normal processing process, the driving mechanism drives the rotation of the parts on the support structure, and then the displacement of the tool relative to the tool on the tool fixing structure occurs, and finally the displacement of the tool relative to the parts occurs to turn. Since the support structure and the tool fixing structure are installed on the hardened ground, the initial installation precision between the two is very low. Even if the relative installation position of the support structure and the tool fixing structure is adjusted subsequently, due to the structural limitation of the support structure and the tool fixing structure, the adjustment difficulty is great, the adjustment range is small, and the relative installation position of the support structure and the tool fixing structure cannot be fixed by re-punching. Therefore, the processing precision of the temporarily built lathe structure is difficult to meet the required processing precision requirement. Therefore, this kind of temporarily built lathe structure generally solves such problems by increasing the adjustment freedom of the tool fixing structure. The conventional tool fixing structure can only realize the adjustment in two directions of longitudinal and transverse directions in the horizontal plane, and the overall precision is guaranteed by the base of the lathe. The tool fixing structure of the conventional lathe is difficult to adapt to such processing site due to the unguaranteed level of the base. SUMMARY
