Description
Technical field
The utility model is related to the pulling chuck structure that a kind of vertical broaching machine is used.
Background technology
Broaching tool is the forming tool for broaching, and broaching tool can be used to process through hole, straight line or the song of various cross sectional shapes
Line outer surface.Broaching tool is generally made up of head, neck, transition portion, front pilot, cutting portion, calibration portion, rear pilot, afterbody.Head
Portion is the coupling part of broaching tool and lathe, for clamping broaching tool, transmits power.The effect of chuck is connection broaching tool head and drawing
Bed.The monoblock type special fixture that uses is wasted time and energy when product is remodeled at present, broaching machine main shaft orientation hole for a long time with broaching tool handle of a knife
Friction, causes loss of significance fast.Frequently changing chuck causes machine body fragile with chuck connection place, and machine tool accuracy declines,
The circular runout of mode fixture broaching tool is difficult.And processed during part using broaching machine, the claw for changing pulling chuck is very numb
It is tired.Claw is generally divided into upper clipping claw and lower claw two parts.Replacing claw is typically a collet body and is unloaded from main cargo chute, removes
Broaching machine outer cover, spring, sleeve, could change claw.Single monoblock type chuck weighs 26.8 kilograms, in general, changes once
Claw needs more than 70 minutes.
The content of the invention
The purpose of this utility model is to provide a kind of split type pulling chuck of vertical broaching machine, overcomes monoblock type pulling chuck
When product is remodeled, process is cumbersome and influences the shortcoming of part processing progress and broaching machine precision.
A kind of split type pulling chuck of vertical broaching machine, it is characterised in that：Including chuck main shaft, grip slide, guide pin bushing, square
Broaching tool pawl, keyway, screw, chuck main shaft connection lathe grip slide, set keyway on chuck main shaft, and guide pin bushing is solid by screw
Chuck front-end of spindle is scheduled on, open pore is provided with chuck main shaft and is convenient for changing square broach pawl, clamped by the way that design is rotary
Sliding block and square broach pawl structure, split mechanism is made by vertical broaching machine pulling chuck, realizes that a sleeve clamp processes multiclass product,
Square broach pawl and guide pin bushing are changed according to broaching tool handle of a knife external diameter, realizes that product is quickly remodeled.Instead of product and remodel need to change folder
Head, the complicated processes of correction debugging chuck.
A kind of split type pulling chuck of vertical broaching machine, it is characterised in that：The key of width 10mm depths 8mm on increasing on chuck main shaft
Groove, increases the width 40mm square through slots of 65mm long in grip slide, and square broach pawl planform is box-shaped, in chuck
Guide pin bushing is designed at main shaft and broaching tool handle of a knife cooperation, original card slot type connection is changed.Guide pin bushing can be realized according to different drawings
Knife handle of a knife is changed, and is not required to change chuck, improves chuck service life.
The utility model has the advantages that：The utility model uses Split type structure, designs rotary sliding block and square broach pawl,
Product is remodeled need not change chuck, and grip slide is rotatable, and square broach pawl is removed and installed conveniently.Change this novel separated knot
Structure, changes a claw and only needs to 40 minutes.With lathe connection place without often dismounting, reduce disassembly process causes pulling chuck
Fixture assembling hole precision damage.The square configuration of square broach pawl increases contact surface, and clamping rigidity is greatly improved.Lead
Set can be changed according to different broaching tool handle of a knifes, change monoblock type broaching tool location hole because being rubbed with broaching tool handle, fragile, be made
With the shortcoming that the life-span is low.Guide pin bushing has protective effect to chuck simultaneously, only just needs to change after guide pin bushing and broaching tool handle friction damage
Guide pin bushing, is not required to change chuck, improves chuck service life.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；Fig. 2 is open pore position view of the present utility model；
In figure：Chuck main shaft 1, grip slide 2, open pore 3, guide pin bushing 4, square broach pawl 5, keyway 6, screw 7.
Specific embodiment
Describe the implementation method of the utility model structure in detail in conjunction with accompanying drawing：
A kind of split type pulling chuck of vertical broaching machine, it is characterised in that：Including chuck main shaft 1, grip slide 2, guide pin bushing 4,
Square broach pawl 5, keyway 6, screw 7, the connection lathe of chuck main shaft 1 grip slide 2, increase width 10mm depths on chuck main shaft 1
The keyway 6 of 8mm, guide pin bushing 4 is fixed on the front end of chuck main shaft 1 by screw 7, open pore 3 is provided with chuck main shaft 1 and is convenient for changing
Square broach pawl 5, increases the width 40mm square through slots of 65mm long, according to different product and different broaching tool knives in grip slide 2
Handle, is changed at rotation grip slide 2 to open pore 3, and unclamping screw 7 according to different product and different broaching tool handle of a knifes rotates to
Guide pin bushing 4 is changed in macropore.Chuck main shaft 1 is only needed by that on broaching machine, chuck main shaft 1 need not be dismantled when product is remodeled
Change square broach pawl 5, guide pin bushing 4.When changing square broach pawl 5, side screw is unclamped, grip slide 2 turns clockwise 45 degree,
4 square broach pawls 5 are changed, then counterclockwise to 45 degree of twisting side screws again.When changing guide pin bushing 4, unclamp screw 7 and rotate to
In macropore, the guide pin bushing 4 matched with handle of a knife is changed, then tighten screw 7.After the completion of remodeling, the keyway 6 on chuck main shaft 1 passes through
Screw is spacing, fixes to clamp sliding block 2, prevents grip slide 2 from rotating.
By such mode of remodeling, pulling chuck, without often dismounting, reduces disassembly process and leads with lathe connection place
The fixture assembling hole precision of cause is damaged.The square configuration of square broach pawl 5 increases contact surface, clamping is greatly improved firm
Property.Product is remodeled need not change chuck, and grip slide 2 is rotatable, and square broach pawl 5 is removed and installed conveniently.Guide pin bushing 4 can be with root
Changed according to different broaching tool handle of a knifes, changed monoblock type broaching tool location hole because being rubbed with broaching tool handle, fragile, service life is low
Shortcoming.Guide pin bushing 4 has protective effect to chuck simultaneously, and only guide pin bushing 4 rubs with broaching tool handle, as long as changing guide pin bushing 4 after damage,
It is not required to change chuck, improves chuck service life.
Above content is to combine specific preferred embodiment further detailed description of the utility model, it is impossible to
Assert that specific implementation of the present utility model is confined to these explanations.For the ordinary skill of the utility model art
For personnel, make some equivalent substitutes or obvious modification without departing from the concept of the premise utility, and performance or
Purposes is identical, then should be considered as belonging to the protection domain of claims determination that the utility model is submitted to.
