Abstract

The invention discloses a machine tool drilling fixing device. The machine tool drilling fixing device comprises a bottom plate and a lead screw. The bottom plate is fixedly provided with a main supporting plate. The center position of the main supporting plate is fixedly provided with a positioning stud in a welded manner. The positioning stud is sleeved with a pressing plate. The main supportingplate is symmetrically provided with positioning pins. The main supporting plate is internally and rotationally connected with a lead screw. The bottoms of the positioning pins are integrally provided with nuts. The bottom of the bottom plate is fixedly connected with a top plate through bolts. The top plate is installed on an output shaft of a stepping motor through fixing pins. According to themachine tool drilling fixing device, the lead screw drives the positioning pins to do rectilinear motion and position a flange plate, positioning is accurate, the speed is large, and the drilling precision is advantageously improved; the pressing plate and the two positioning pins are distributed around the flange plate in a cross-shaped manner, the flange plate can be effectively fixed, and thestability of the flange plate is improved; and by means of the stepping motor, the bottom plate can be driven to drive the flange plate to rotate, and the flange plate is advantageously rotated so that drilling operation can be carried out on different positions.

Description

technical field [0001] The invention belongs to the technical field of machine tool fixing devices, and in particular relates to a machine tool drilling and fixing device. Background technique [0002] Drilling machine refers to a machine tool that mainly uses a drill bit to process holes in a workpiece. Usually the drill bit rotates as the main movement, and the axial movement of the drill bit is the feed movement, and the machining accuracy is relatively low. When drilling the flange, it is necessary to fix the flange. In order to save cost, the existing vertical drilling machine tool has a relatively simple structure, and its spindle box can only feed up and down along the column. When drilling, it is necessary to mark the center position of the drilling hole on the flange first. Drill holes one by one. After each hole is drilled, retract the tool, remove the flange from the fixture, align the next drilling position with the center of the drill bit, then clamp it, and c...
