Description
Technical field
The utility model relates to machining fixture, is specifically related to a kind of fixture, is arranged in plane bench and just can carries out processing keyway.
Background technology
The high efficiency processing method of gear inner hole key slot draws key exactly, although broaching machine cutter has processing endoporus to the function of key, but this processing does not have special tooling in the past, therefore broaching machine cutter can not ensure the precision of endoporus to key position, so most cases machining gears endoporus adopts slotting machine, Linear cut or numerical control broaching machine cutter to key, but the processing method efficiency of slotting machine, Linear cut is extremely low, and high with numerical control broaching machine tooling cost, and Repairing of Numerically Controlled Machine Tool cost is also very high.
Summary of the invention
The purpose of this utility model is to provide a kind of broaching machine cutter to key guide pin bushing, and this fixture just can processed on plane bench cutter keyway, be easy to operate and the constant product quality of processing, qualification rate is high, efficiency is high.
Broaching machine cutter of the present utility model is to key guide pin bushing, comprise broaching machine cutter, pad, fairlead main body and positioning key, it is characterized in that fairlead main body central diameter to be arranged in hole, broaching machine cutter positioning by pad, by workpiece hole through behind fairlead main body cylinder positioning spline position, in positioning spline, insert positioning key; By positioning spiro pit on screw, the large footpath of fairlead main body and pad, fairlead main body is adjusted level; Fairlead main body lacks reducing cylinder for circle, this column vertical in circle lack of water plane circle centre position has broaching tool keyway, being separated by 180 degree has positioning spline, two keyway through shafts to, in the middle part of cylinder, large footpath outer rim has the positioning spiro pit of symmetry.
The utility model compared with prior art has the following advantages: this covering device is without the need to line, and handling gear is convenient, fast, efficiency is high; This covering device lubrication is convenient, the life-span is longer; This covering device structure is simple, and manufacturing cost is lower.

Detailed description of the invention
To be further illustrated by detailed description of the invention below in conjunction with accompanying drawing.
The broaching machine cutter of the design is to key guide pin bushing, see accompanying drawing 1,2, it is characterized in that fairlead main body 4 central diameter to be arranged in broaching machine cutter 1 locating hole by pad 2, by workpiece 3 hole through behind fairlead main body 4 cylinder positioning spline 43 position, in positioning spline 43, insert positioning key 5; By positioning spiro pit 42 and pad on screw, the large footpath of fairlead main body 4, fairlead main body 4 is adjusted level.
Fairlead main body 4 shown in Fig. 3 a, Fig. 3 b is the scarce reducing cylinder of circle, this column vertical in circle lack of water plane circle centre position has broaching tool keyway 41, being separated by 180 degree has positioning spline 43, article two, keyway through shaft to, in the middle part of cylinder, large footpath outer rim has symmetrical positioning spiro pit.
The large cylindrical both sides, footpath of described fairlead main body 4 are at least provided with two positioning spiro pits 42, and described positioning spiro pit becomes 180 degree of horizontal distribution.
Described broaching tool keyway 41 keyway wide with broaching tool with wide.Described positioning spline 43 keyway wide with workpiece 3 keyway with wide.
Positioning key 5 key shown in Fig. 4 a, Fig. 4 b is wide wide with wide with workpiece 3 keyway.
Broaching machine cutter is installed the broaching machine cutter of the design to key guide pin bushing, operating procedure is:
Steps A, by fairlead main body 4 by being arranged in broaching machine cutter 1 locating hole after positioning spiro pit 42 and pad 2 adjustment level.Workpiece 3 is through in the fairlead main body 4 away from broaching machine cutter 1 one end.
Step B, broaching tool is carried out broaching first keyway through fairlead broach slot of FIG 41.
Step C, broaching first keyway after by workpiece 3 centrally axle revolve turnback, workpiece 3 keyway alignment guide cover positioning spline 43.Positioning key 5 is pierced in fairlead positioning spline 43.
Step D, broaching tool is carried out broaching second keyway through fairlead broach slot of FIG 41.
