Abstract
Two-wayly can be arranged on the reamer in Deflection drill, it relates to a kind of reamer, is specifically related to a kind of reamer that can two-wayly be arranged in Deflection drill.The utility model is that the short taper-shank reamer of the existing Mohs of solution is low with poor, the coaxial precision of the locating effect between Deflection drill, and can only unidirectionally install between the two, causes the problem that the range of work is narrow.A kind of reamer that can two-wayly be arranged in Deflection drill described in the utility model is made into integration from left to right by handle of a knife, boss and cutter head, boss protrudes from handle of a knife and cutter head is arranged, the cross section of boss is kidney-shaped, the center line of the length direction of boss and the central axis in shank length direction are arranged, left side and the right side of boss are plane, the left side of boss is arranged with two through holes along the length direction of boss, the left end portion of cutter head is made into integration by six cutters tooth, the anterior angle B of each cutter tooth is 4 °, and the relief angle C of each cutter tooth is 10 °.The utility model is for processing turbine blade root place locking hole.
Description
Technical field
The utility model relates to a kind of reamer, is specifically related to a kind of reamer that can two-wayly be arranged in Deflection drill.
Background technology
Turbine blade is assemblied on impeller of rotor, after assembling, needs to process locking pin-and-hole at blade root place, by alignment pin locking one, completes the installation of often enclosing blade.Because impeller spacing at different levels is very narrow, special Deflection drill must be used process, short for Mohs taper-shank reamer is arranged on pin hole processing on Deflection drill, but the short taper-shank reamer of Mohs is low with poor, the coaxial precision of the locating effect between Deflection drill, and unidirectionally can only install between the two, cause the range of work narrow.
Utility model content
The utility model is that the short taper-shank reamer of the existing Mohs of solution is low with poor, the coaxial precision of the locating effect between Deflection drill, and can only unidirectionally install between the two, causes the problem that the range of work is narrow, and then proposes a kind of reamer that can two-wayly be arranged in Deflection drill.
The utility model is the technical scheme taked that solves the problem: described in the utility model a kind of can the reamer be two-wayly arranged in Deflection drill be by handle of a knife, boss and cutter head are made into integration from left to right, boss protrudes from handle of a knife and cutter head is arranged, the cross section of boss is kidney-shaped, the center line of the length direction of boss and the central axis in shank length direction are arranged, left side and the right side of boss are plane, the left side of boss is arranged with two through holes along the length direction of boss, the left end portion of cutter head is made into integration by six cutters tooth, the anterior angle B of each cutter tooth is 4 °, the relief angle C of each cutter tooth is 10 °.
The beneficial effects of the utility model are: reamer handle of a knife is arranged in Deflection drill by the utility model, adopt and a boss is set between handle of a knife and cutter head, left side and the right side of boss are plane, can fit tightly with the end face of Deflection drill, and utilize holding screw by reamer tightly on Deflection drill, good positioning effect, coaxial precision is within 0.02mm, two end faces of Deflection drill all can install the utility model, thus realize the processing that a reamer and Deflection drill can complete left and right sides blade root locking hole, expand the range of work.
Accompanying drawing explanation
Fig. 1 is front view of the present utility model, and Fig. 2 is the A-A place sectional view of Fig. 1, and Fig. 3 is the partial top view of Fig. 1.
Detailed description of the invention
Detailed description of the invention one: composition graphs 1 to Fig. 3 illustrates present embodiment, a kind of described in present embodiment can the reamer be two-wayly arranged in Deflection drill be by handle of a knife 1, boss 3 and cutter head 2 are made into integration from left to right, boss 3 protrudes from handle of a knife 1 and cutter head 2 is arranged, the cross section of boss 3 is kidney-shaped, the center line of the length direction of boss 3 and the central axis of handle of a knife 1 length direction are arranged, left side and the right side of boss 3 are plane, the left side of boss 3 is arranged with two through hole 3-1 along the length direction of boss 3, the left end portion of cutter head 2 is made into integration by six cutter tooth 2-1, the anterior angle B of each cutter tooth 2-1 is 4 °, the relief angle C of each cutter tooth 2-1 is 10 °.
In present embodiment, the handle of a knife 1 of reamer is inserted in the hole of Deflection drill end face, in the flat groove be positioned on Deflection drill end face of boss 3.Be provided with a holding screw in each through hole 3-1 on boss 3, reamer is fixed together by holding screw and Deflection drill.
Detailed description of the invention two: composition graphs 1 to Fig. 3 illustrates present embodiment, the cross section of handle of a knife 1 described in present embodiment is circular, the lateral wall of handle of a knife 1 is provided with keyway 1-1.Setting like this, the diameter D of handle of a knife 1 is 12mm, can with the hole close fit of Deflection drill end face, the width W of keyway 1-1 is 3mm, is provided with driving key in keyway 1-1, is used for transmitting torque.Other compositions are identical with detailed description of the invention one with annexation.
Detailed description of the invention three: composition graphs 2 illustrates present embodiment, described in present embodiment, the tool cutting edge angle D of cutter head 2 is 15 °.Setting like this, the left end portion of cutter head 2, for slightly to cut with scissors part, first carries out rough cut processing, then utilizes the excircle part that the right end portion diameter of cutter head 2 is 12mm to carry out finish reaming processing.Other compositions are identical with detailed description of the invention one with annexation.
Operation principle
Operationally, handle of a knife 1 of the present utility model is inserted in the hole of Deflection drill end face, the end face of boss 3 and the end face of Deflection drill fit tightly, and be fixed together by holding screw, utilize the left end portion of cutter head 2 to carry out rough cut processing, then utilize the excircle part that the right end portion diameter of cutter head 2 is 12mm to carry out finish reaming processing.Two end faces of Deflection drill all can install the utility model, thus realize the processing that a reamer and Deflection drill can complete left and right sides blade root locking hole, expand the range of work.
