Description
Technical field
The utility model relates to a kind of frock for processing TS140 bull-dozer boss interior key, belongs to metal working technical area.
Background technology
Boss is one of critical piece of TS140 bull-dozer, these parts are the structural members (referring to Fig. 1) be welded by end large-flange, the little flange of axle head and tube connector therebetween, its centre bore is taper hole and the inwall of taper hole is provided with six for installing the axial keyway of adapter sleeve, and the positional precision of each keyway and dimension precision requirement are very high.Because six keyways are in inside cavity, directly add the positional precision and relation size that cannot ensure keyway man-hour with broaching machine, process before welding, be not only difficult to the positional precision ensureing keyway, and during welding, the location of axle head size flange is also very inconvenient.Therefore, six keyways how processing TS140 bull-dozer boss inside are quickly and accurately puzzlement relevant technologies personnel's difficult problems always.
Utility model content
The purpose of this utility model is the drawback for prior art, provides a kind of bull-dozer boss interior key processing tool of simple to operate, accurate positioning, to improve working (machining) efficiency and the crudy of boss.
Problem described in the utility model realizes with following technical proposals:
A kind of bull-dozer boss interior key processing tool, formation comprises supporting disk, axle, circular cone positioning body and keyway locating clamp plate, and described axle is parallel with the direction of motion of broaching machine cutter, and its one end is fixed on broaching machine by supporting disk; Described circular cone positioning body passes through its centre bore coaxial package in axle, the inwall of its conical surface and bull-dozer boss matches and is provided with multiple axial Card trough, described keyway locating clamp plate is positioned at a Card trough of circular cone positioning body, and its one end is inserted in the locating hole on supporting disk.
Above-mentioned bull-dozer boss interior key processing tool, described axle is provided with positioning body anticreep baffle plate away from one end of supporting disk, and described positioning body anticreep baffle plate is pressed in the end of circular cone positioning body and is fixedly connected with axle.
Above-mentioned bull-dozer boss interior key processing tool, the butt end of described circular cone positioning body and the conical surface of taper end are equipped with slipmat.
Above-mentioned bull-dozer boss interior key processing tool, is provided with alignment pin between described slipmat and circular cone positioning body.
Above-mentioned bull-dozer boss interior key processing tool, the Card trough on described circular cone positioning body arranges six, and they are uniformly distributed around circular cone positioning body.
The utility model, using the taper hole inwall of bull-dozer boss as positioning datum, utilizes the self-locking property clamping work pieces of circular cone positioning body, utilizes keyway locating clamp plate to realize the accurate location of each keyway simultaneously.The advantages such as this frock has simple to operate, and positioning precision is high, speed is fast, solve the difficult problem that boss six keyway is not easily processed well, drastically increase working (machining) efficiency and the crudy of boss.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail.
Fig. 1 is the structural representation of boss.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is internal structure schematic diagram of the present utility model.
Fig. 4 is the clamping schematic diagram of workpiece.
In figure, each label is: 1, supporting disk; 2, butt end slipmat; 3, taper end slipmat; 4, axle; 5, set bolt; 6, positioning body anticreep baffle plate; 7, alignment pin; 8, workpiece; 9, keyway; 10, supporting disk and broaching machine connecting hole; 11, keyway locating clamp plate; 12, circular cone positioning body; 13, large flange; 14, little flange.
Detailed description of the invention
Referring to Fig. 2 ~ Fig. 4, the utility model is primarily of parts compositions such as supporting disk 1, alignment pin 7, slipmat (comprising butt end slipmat 2 and taper end slipmat 3), axle 4, positioning body anticreep baffle plate 6, keyway locating clamp plate 11, circular cone positioning body 12, set bolts 5.Wherein butt end slipmat 2 and taper end slipmat 3 are arranged on the butt end of circular cone positioning body 12 and the conical surface of taper end by bolt and alignment pin 7 respectively, the effect of slipmat increases the frictional force between workpiece and circular cone positioning body 12, make the fixing more firm of workpiece, the conical surface due to circular cone positioning body 12 there are six Card troughs, therefore butt end slipmat 2 and taper end slipmat 3 are six, each butt end slipmat 2 and taper end slipmat 3 are arranged between two adjacent Card troughs, the thickness of butt end slipmat 2 and taper end slipmat 3 is 45mm, after installing slipmat, the butt end radius of the assembly that circular cone positioning body 12 and slipmat are formed is 143mm, taper end radius is 136.25mm, just coordinate the workpiece that will process.Supporting disk 1 is fixed on broaching machine one end by its connecting hole.Axle 4 is fixed on supporting disk 1 by interior hexagonal cylindrical hook bolt.Circular cone positioning body 12 is sleeved in axle 4, for fixed axis end flanges (workpiece).Positioning body anticreep baffle plate 6 is fixed on axle 4 end by set bolt 5, and its effect prevents circular cone positioning body 12 from coming off with workpiece when workpiece loading and unloading.Keyway locating clamp plate 11 is for realizing the location of circular cone positioning body 12 at circumferencial direction.
When using this frock to process six keyways of TS140 bull-dozer boss, first this frock assembled and be arranged on broaching machine, then workpiece is sleeved on circular cone positioning body 12, keyway locating clamp plate 11 inserts in the locating hole of supporting disk 1 and a Card trough of circular cone positioning body 12, process first keyway, after first keyway completion of processing, simultaneously in rotational workpieces and the whole process of circular cone positioning body 12(between workpiece and circular cone positioning body 12 without relative motion), keyway locating clamp plate 11 is made to insert in the locating hole of supporting disk 1 and another Card trough of circular cone positioning body 12, process second keyway, so repeatedly, until process all keyways, finally unload workpiece.
