Abstract
The present invention provides a kind of interchangeable handle of a knife for race broach, and it is by handle of a knife body, screw, drift, alignment pin composition.One end that handle of a knife body is connected with broaching tool cutter hub is provided with clamping slot, and clamping slot is provided with through hole, to be inserted for the alignment pin of connection broaching tool cutter hub and handle of a knife body.When broaching tool cutter hub clamping is entered into the clamping slot in handle of a knife body, dead slot is left between broaching tool cutter hub and handle of a knife body so that drift loads and strikes tight drift.Broaching tool cutter hub carries consistent taper with drift.Handle of a knife body is provided with screwed hole, for use in mounting screw to compress drift.
Description
Technical field
The present invention provides a kind of interchangeable race broach handle of a knife.A kind of more particularly to processing turbine rotor wheel disc race
With the interchangeable handle of a knife in shank type race broach.
Background technology
In turbine making, turbine rotor is the power section of steam turbine, and the quality of crudy will directly affect
To the performance of whole steam turbine, multistage wheel disc is the chief component of rotor.The quality of wheel disc side entry machining will directly affect
The output and Vibration Condition of steam turbine, the processing of race is link the most key, the most difficult in rotor machining.Wheel disc race
Processing Broaching Technology is gradually changed to by traditional special plane Milling Process.And in Broaching Technology using to be a kind of high accuracy, it is high
Efficiency, low cost, the race broach group of long-life, the race broach group is by rough race deep-draw knife, the rough wide drawing of race tooth form
Knife, finish draw race crest top land broaching tool, finish draw race omoplate surface broach, finish draw race tooth form broaching tool combine.These broaching tools
Broaching tool handle of a knife is carried, but lacks good interchangeability between these broaching tool handle of a knifes.
The content of the invention
The technical problems to be solved by the invention are the race broach handle of a knife for providing a kind of rapid interchangeable.
In order to solve the above technical problems, the interchangeable handle of a knife of the present invention is by handle of a knife body, screw, drift, alignment pin composition.
One end that handle of a knife body is connected with broaching tool cutter hub is provided with clamping slot, and clamping slot is provided with through hole, so as to for connection broaching tool cutter hub and knife
The alignment pin insertion of handle body.When broaching tool cutter hub clamping is entered into the clamping slot in handle of a knife body, broaching tool cutter hub and handle of a knife body
Between leave dead slot so that drift loads and strikes tight drift.Broaching tool cutter hub carries consistent gradient with drift.Handle of a knife body is provided with
Screwed hole, drift is compressed for use in installation fixing screws.The handle of a knife bulk material of the present invention uses common alloy steel, is heat-treated
Hardness is between HRC38-43 so that handle of a knife body has certain toughness and wearability, and broaching tool cutter hub uses high-speed steel.Due to
Existing race broach is assembled set broaching tool, so using split type handle of a knife all broaching tools in complete broaching tool can use
Mutually isostructural handle of a knife, so that handle of a knife can be produced in batches, manufacturing cost is reduced, improves processing efficiency, also causes handle of a knife
Interchangeability with height.
As a further improvement on the present invention, eccentric semicircle has been done among alignment pin.
As a further improvement on the present invention, fixing screws setting height(from bottom) is not above the tooth height of broaching tool blade first.

Embodiment：
As shown in Figures 1 to 5, interchangeable handle of a knife of the invention is made up of handle of a knife body 1, screw 2, drift 3, alignment pin 4, handle of a knife
One end that body 1 is connected with broaching tool cutter hub 5 is provided with clamping slot 7, and clamping slot 7 is provided with through hole 6, so as to for connection broaching tool cutter hub 5 with
The alignment pin 4 of handle of a knife body 1 inserts.When the clamping of broaching tool cutter hub 5 is entered into the clamping slot 7 in handle of a knife body 1, broaching tool cutter hub 5 with
Dead slot is left between handle of a knife body 1 so that drift 3 loads and strikes tight drift 3.Broaching tool cutter hub 5 carries consistent gradient with drift 3.Knife
Handle body 1 is provided with screwed hole 8, for use in mounting screw 2 to compress drift 3.The material of handle of a knife body 1 of the present invention is using general
Logical steel alloy, heat treatment hardness is between HRC38-43 so that handle of a knife body 1 has certain toughness and wearability, broaching tool knife
Body 5 uses high-speed steel.Eccentric semicircle is provided among alignment pin 4, so as to when tapping drift 3, due to drift 3 and broaching tool cutter hub 5
With gradient, therefore a tension force can be produced during drift 3 sinks, the eccentric semicircle of alignment pin 4 will be in the active force
Down so that broaching tool cutter hub 5 moves with handle of a knife body 1 toward opposite direction, broaching tool cutter hub 5 and handle of a knife when drift 3 sinks to certain position
Body 1 will be closely joined together.Broaching tool cutter hub 5 and the process that handle of a knife body 1 assembles are simple, easy to operation, and can improve mutually
It is transsexual.The interchangeable race broach handle of a knife monoblock type handle of a knife that compares is cheaper, economical and practical, and its structure is also suitable in other
Cutter.
