Mirror image thermal balance spindle box structure containing guide rails

The invention discloses a mirror image thermal balance spindle box structure containing guide rails, and relates to the technical field of machine tool fittings. The mirror image thermal balance spindle box structure containing the guide rails comprises a spindle box body, the guide rails are arranged on two sides of the spindle box body, and the spindle box body comprises mirror image parts. It is supposed that the width of the guide rails is Lb, the length is Hb, it is supposed that the width of the mirror image parts is Lc, the length is Hc, a central hole is formed in the center of the spindle box body, first circular holes and second circular holes are separately formed in the guide rails and the mirror image parts, and by penetrating through a center seat transverse axis the center hole, the circle center of the center hole turning 45 degrees clockwise along the transverse axis is taken as a reference line. According to the mirror image thermal balance spindle box structure containing the guide rails, b
