Abstract
The utility model provides a high symmetry keyway graduation milling fixture. Its technical scheme is: a high symmetry keyway graduation milling fixture, the on -line screen storage device comprises a base, T type bolt, the square key, the graduation seat, a spring, the graduation round pin, the bolt, pressing plates, V type piece, graduation tooth axle, press from both sides tight piece and cramp bar, the base passes through T type bolt and the square key is fixed on the milling machine table, the upper left end of base is equipped with the graduation seat, the graduation round pin that it lives with it to be equipped with in the graduation seat hole joins in marriage, the spring pressure equipment is between the boss of graduation seat hole bottom surface and graduation round pin, graduation tooth axle lower extreme is lived with the base hole and is joined in marriage and compress tightly the location by pressing from both sides tight piece, press from both sides tight piece and cramp bar loose joint, the base right side is equipped with the cramp bar with the thread to match mode, the graduation tooth is epaxial to be equipped with V type piece and to be fixed a position by square key and bolt -up, be equipped with the work piece on the V type piece and pass through the bolt -up location by the clamp plate. The beneficial effects are that: a clamping, positioning accuracy is high, and work piece and cutter all do not have displacement and high symmetry on the axis, and the work efficiency is high, and is of high quality.
Description
Technical field
The utility model relates to a kind of high symmetry keyway indexing milling fixture, belongs to clamping tool for machine work technical field.
Background technology
In machining; usually can run into process on axle symmetry requirement reach 0.01mm within keyway; this processes on general milling machine is be beyond one's reach; because keyway milling generally point both sides carries out, after a side milling is good, when moving cutting tool or workpiece milling opposite side; its positioning datum has just become; positioning datum there will be larger mismachining tolerance once becoming, so the positioning datum that neither one is constant, just cannot reach higher machining accuracy.
Summary of the invention
The purpose of this utility model is just to provide a kind of high symmetry keyway indexing milling fixture, for solving the problem.
The technical solution of the utility model is: a kind of high symmetry keyway indexing milling fixture, comprise base, T-shaped bolt, square key, indexing base, spring, index pin, bolt, pressing plate, V-block, calibration tooth axle, clamp and clamping bar, base is fixed on milling machine table by T-shaped bolt and square key, base left upper end is provided with indexing base, the index pin that work is with it joined is provided with in indexing base endoporus, pressure mounting of the spring is between indexing base endoporus bottom surface and the boss of index pin, calibration tooth axle lower end and base endoporus are lived in joining and compressed by clamp and are located, clamp and clamping bar loose joint, clamping bar is provided with screw thread coordinating fashion on the right side of base, calibration tooth axle is provided with V-block and is located by square key and bolted, V-block is provided with workpiece and is fastened by bolts location by pressing plate.
The beneficial effects of the utility model are: clamped one time, and positioning precision is high, and workpiece and cutter all do not have displacement and high degree of symmetry on axis, and work efficiency is high, and quality is good.
Accompanying drawing explanation
Fig. 1 is the utility model structural representation.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described in further detail, known with reference to accompanying drawing 1, a kind of high symmetry keyway indexing milling fixture, comprise base 1, T-shaped bolt 2, square key 3, indexing base 4, spring 5, index pin 6, bolt 7, pressing plate 9, V-block 10, calibration tooth axle 11, clamp 12 and clamping bar 13, base 1 is fixed on milling machine table 14 by T-shaped bolt 2 and square key 3, base 1 left upper end is provided with indexing base 4, the index pin 6 that work is with it joined is provided with in indexing base 4 endoporus, spring 5 is fitted between the boss of indexing base 4 endoporus bottom surface and index pin 6, calibration tooth axle 11 lower end and base 1 endoporus are lived and are joined and compress location by clamp 12, clamp 12 and clamping bar 13 loose joint, clamping bar 13 is provided with screw thread coordinating fashion on the right side of base 1, calibration tooth axle 11 is provided with V-block 10 and by square key and the fastening location of bolt 7, V-block 10 is provided with workpiece 8 and is fastened by bolts location by pressing plate 9.When using the utility model milling high accuracy height symmetry keyway, first install this fixture and workpiece 8 by above-mentioned requirements, then index pin 6 is aimed at the zero graduation of calibration tooth axle 11, tighten clamping bar 13, the side of keyway can be processed, after milling 2/3rds of institute's made allowance, now cut feeding motionless, only allow to lift milling cutter up and down and unclamp clamping bar 13, calibration tooth axle 11 is rotated 180 °, tighten clamping bar 13 again, mill out opposite side, finally, repeat above-mentioned steps, mill surplus, be machined to figure paper size, so namely process qualified high symmetry keyway.
