Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of gantry machining centers, and particularly relates to a spindle power adjusting device for grinding of a gantry machining center. BACKGROUND

[0002] In the field of modern mechanical processing, gantry machining centers have become one of the core devices for processing various parts due to their high efficiency and precision, and are widely used in grinding of parts with complex shapes and high precision requirements.

[0003] Traditional spindle power adjusting devices for grinding of gantry machining centers are usually composed of a machine table, a gantry support, a moving seat, a spindle and other basic structures. The gantry support is used to support the moving seat, the moving seat can move horizontally on the gantry support to expand the processing range, and the spindle is installed on the moving seat to perform grinding tasks.

[0004] However, the existing spindle power adjusting device for grinding of gantry machining centers has a single adjusting mode, and mostly can only realize simple movement of the spindle in the horizontal or vertical direction, which is difficult to meet the diversified processing needs of workpieces of different shapes and positions. When facing workpieces with complex curved surfaces or irregular shapes, the angle and position of the spindle cannot be flexibly adjusted, resulting in decreased processing precision and reduced processing efficiency.

[0005] On the other hand, due to the limited adjusting mode, the workpiece surface can only be ground in a fixed manner during processing, which often requires multiple grinding processes to achieve the flatness of the ground surface, resulting in low processing efficiency. SUMMARY

[0006] The present application solves the problems in the related art and proposes a spindle power adjusting device for grinding of a gantry machining center, which solves the problem of limited spindle adjusting mode for grinding of existing gantry machining centers and the difficulty in quickly grinding the surface flat.

[0007] In order to solve the above technical problems, the present application is realized by the following technical scheme: a main shaft power adjusting device for gantry machining center grinding, comprising a machine table, a gantry support is vertically installed above the machine table, a moving seat is slidingly installed on the upper end surface of the gantry support, and a driving part one for driving the horizontal movement of the moving seat is arranged on the gantry support, an adjustable support is slidingly installed on the front end surface of the moving seat, and a driving part two for driving the lifting of the adjustable support is arranged on the moving seat, an isolation seat is rotatably installed on the front end surface of the adjustable support, and a horizontal motor for driving the rotation of the isolation seat is installed on the adjustable support, a main shaft box is fixedly installed on the front end surface of the isolation seat, a rotating shaft shell is vertically fixedly installed on the main shaft box, an adjustable main shaft is rotatably installed in the rotating shaft shell, a vertical motor for driving the rotation of the adjustable main shaft is fixedly installed on the main shaft box, and a hydraulic cylinder one for driving the downward movement of the adjustable main shaft is also fixedly installed on the main shaft box.
