Description

Technical Field

[0001] The utility model belongs to the technical field of milling machine fixtures, in particular to a milling machine fixture for processing large bridge pads. Background Art

[0002] A milling machine primarily uses a milling cutter to mill various workpiece surfaces. The primary motion is usually the rotation of the cutter, while the movement of the workpiece and cutter is the feed motion. In addition to milling planes, grooves, gear teeth, threads, and spline shafts, milling machines can also process more complex surfaces. Their efficiency is higher than that of planers, and they are widely used in machinery manufacturing and repair.

[0003] Milling machines are versatile machine tools that can produce flat surfaces (horizontal and vertical), grooves (keyways, T-slots, dovetail slots, etc.), toothed parts (gears, spline shafts, sprockets), helical surfaces (threads, spiral grooves), and various curved surfaces. They can also be used for machining the surfaces of rotating objects, machining internal holes, and performing cut-off operations. During operation, a workpiece is mounted on a worktable or an accessory such as an indexing head. The milling cutter rotates as the primary motion, supplemented by the feed motion of the worktable or milling head, to achieve the desired surface finish. Because of the multi-edge interrupted cutting, milling machines offer high productivity.

[0004] Milling machines require fixtures when machining workpieces. Traditional milling machines use fixed fixtures, limiting milling to a single horizontal surface and preventing adjustments to angles and positions based on actual working conditions. Pads of varying thicknesses are commonly used in bridge construction. Due to their irregular shapes and varying thicknesses, these pads are difficult and inefficient to manufacture using traditional milling machine fixtures. Utility Model Content

[0008] The fixture base includes a base plate provided at the end of the support column, and four base panels provided around the base plate and connected end to end. The base plate is perpendicular to the longitudinal axis of the support column.

[0009] Each base plate is provided with a pair of bolts A, and eight bolts A together form the clamping assembly;

[0010] The angle adjustment assembly includes eight bolts B provided on the base plate, with two bolts B distributed on each corner of the base plate.

[0011] Furthermore, a nut A that matches the bolt A is welded on the base plate, and the bolt A is threadedly connected to the nut A.

[0012] Furthermore, the ends of the screw rods of the eight bolts A are arranged opposite each other in pairs, and the axis of the screw rods of the bolts A is perpendicular to the axis in the length direction of the support column.

[0013] Furthermore, the bolt A is a hexagonal bolt, and the nut A is a hexagonal nut.

[0014] Furthermore, a threaded hole B that is compatible with the bolt B is provided on the base plate, and a nut B that is compatible with the bolt B and is coaxially distributed with the threaded hole B is welded on the base plate.
