Abstract
The utility model discloses a machine presss from both sides formula combination broach, including the cutter body that is equipped with mounting hole, cutting tooth and calibration tooth include the cylindrical blade that many circles were equipped with circular cone installation face, install the holding screw that is used for adjusting the flexible volume of cylindrical blade in the mounting hole, cylindrical blade one end be located the mounting hole and with the holding screw contact, be equipped with the set screw that is used for restricting the cylindrical blade degree of freedom on the circular cone installation face. The utility model discloses by integral structure in the past change split type package assembly into, the cutting tooth of damage is removable, has avoided scrapping of whole broach.
Description
Technical field
The utility model relates to Machining Technology field, is specially a kind of clip type built-up broach.
Background technology
In machine driving numerous parts need process spline, and process spline need use broaching tool, broaching tool is in use often because indivedual cutting teeth tipping or wearing and tearing cause scrapping of whole broaching tool.Because the material manufacturing broaching tool is very expensive, so existing broaching tool greatly wastes raw material, substantially increase heat treatment expense.
Utility model content
Therefore, in order to overcome the deficiency that prior art exists, the utility model provides a kind of and can save material greatly and the clip type built-up broach of heat treatment expense.
The utility model clip type built-up broach comprises the cutter hub being provided with installing hole, cutting teeth and finishing teeth, described cutting teeth and finishing teeth comprise the cylinder blade that multi-turn is provided with circular cone installed surface, screw for adjusting cylinder blade stroke is installed in described installing hole, described cylinder blade one end is positioned at installing hole and contacts with screw, and described circular cone installed surface is provided with the hold-down screw for limiting the cylinder blade free degree.
The utility model changes split type package assembly into by monolithic construction in the past, and the cutting teeth of damage is replaceable, avoids scrapping of whole broaching tool.According to the different optional different anterior angle of broaching material, simultaneously because the rake face of cylinder blade was the center line of self therefore had certain angle, rear flank to make cutting more brisk, cutting force is less, and the reduction of cutting force just can regulate larger rise per tooth to reduce the distribution of the number of teeth.For improving the service life of cylinder blade and reducing cutter and can easily use the method for coating to realize with the friction of workpiece, monoblock type broaching tool restriction with coating apparatus space too huge due to cutter hub and cannot apply and apply costs rather expensive.Use, reconditioning are namely replaceable afterwards several times, body portion can continue to use cylinder blade.This broaching tool leaves interface in front end can carry out preprocessing to product hole for installing fairlead, circular broach sheet and chamfering blade etc.The head of broaching tool and afterbody leave band square thread pull bar interface section, for install pull bar and griffe bar thus decrease broaching tool overall length and be more conducive to processing.This broaching tool can greatly save material and heat treatment expense, really embodies " using the best steel to make the knife's edge ".Especially more obvious in large-scale broaching tool effect.
After reading the detailed description of the utility model embodiment by reference to the accompanying drawings, other features of the present utility model and advantage will become clearly.

Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention of the present utility model, the utility model clip type built-up broach is made the following instructions.
Embodiment: a kind of clip type built-up broach, comprise the cutter hub 1 being provided with installing hole 9, cutting teeth 10 and finishing teeth 11, described cutting teeth 10 and finishing teeth 11 comprise the cylinder blade 6 that multi-turn is provided with circular cone installed surface 12, screw 8 for adjusting cylinder blade 6 stroke is installed in described installing hole 9, described cylinder blade 6 one end is positioned at installing hole 9 and contacts with screw 8, and described circular cone installed surface 12 is provided with the hold-down screw 7 for limiting cylinder blade 6DOF.As embodiment one, between bottom the installing hole 9 that same circle is adjacent, be provided with partition 13.As embodiment two, mutually run through between bottom the installing hole 9 that same circle is adjacent, the spaced installing hole 9 of adjacent cylinder blade 6.The shape of described cylinder blade 6 is rectangular blade or involute shape.Described cutter hub 1 front end is provided with the draw rod attachment part 14 for installing pull bar, described cutter hub 1 tail end be provided with for install griffe bar griffe bar connecting portion 15, described draw rod attachment part 14 and griffe bar connecting portion 15 and be provided with square thread.Be provided with between described draw rod attachment part 14 and cutter hub 1 and draw front assisted parts 16, described in draw the front end of front assisted parts 16 to be provided with fairlead 4, described in draw the rear end of front assisted parts 16 to be provided with circular broach sheet 3 and chamfering blade 2.Described cutting teeth 10 comprises roughing tooth 17 and finishing tooth 18.
During use, first highly consistent cylinder blade 6 is arranged in installing hole 9, and is pressed on circular cone installed surface 12 by hold-down screw 7, thus limit all frees degree of cylinder blade 6.Then on deflection instrument, detect beating and diameter of the rear blade external diameter of assembling, underproof words detachably descend cylinder blade 6 to carry out adjustment to requiring by screw 8.The effect one of screw 8 is the high-precision requirement making up equipment drilling depth, and another is exactly realize rise per tooth adjustable.Require to need screw 8 if equipment can reach higher drilling depth, thus greatly reduce the regulation time of cylinder blade 6, but lose the performance-adjustable of rise per tooth.Because the number of product spline is different, clip type built-up broach divides embodiment one and embodiment two, embodiment one is unlikely to the occasion run through for having enough spaces to hole at adjacent two between cog of circumferencial direction, the installing hole 9 that cylinder blade 6 is housed because adjacent runs through cylinder blade 6 can be caused mutually to interfere when mounted.It is more that embodiment two is mainly used in product spline number, in the occasion of broaching tool cutter hub circumferencial direction adjacent teeth close together.Now cylinder blade 6 needs all to need side set all around, and side set broaching tool is at unit length scope internal broaching power more I reduction broaching machine tonnage demand.Cylinder blade 6 can make rectangular blade and involute shape according to product, because the impact of anterior angle can cause the profile errors of involute when making involute shape, therefore essence cut part to adopt less anterior angle, correction portion adopt zero degree hook carry out modified tooth profile error.Fairlead 4, circular broach sheet 3 and chamfering blade 2 are installed in and draw front assisted parts 16 and be fixed by clamp nut 5, all replaceable after these component wears.
Above-described embodiment is the utility model preferably embodiment; but embodiment of the present utility model is not restricted to the described embodiments; change, the modification done under other any does not deviate from Spirit Essence of the present utility model and principle, substitute, combine, simplify; all should be the substitute mode of equivalence, be included within protection domain of the present utility model.
