Description
Technical field
The present invention relates to clamp art, be especially a kind of knuckle shell drilling fixture。
Background technology
The blank of spindle housing needs multiple screwed holes at top are processed, at present it is generally required to first locating and machining hole, holes drilled through use tap tapping again。So namely three are needed to arrive operation；Adding man-hour at fixture, needing every one manufacturing procedure to prepare different fixture clamping, it is impossible to general, and adjust every time, calibration, time-consuming, finally affect working (machining) efficiency；And because passing through the clamping of different fixtures, every one procedure needs to select a datum level or hole, a location, such multiple clamping, affects final machining accuracy。
Summary of the invention
The knuckle shell drilling fixture that the technical problem to be solved in the present invention is to provide a kind of disposable clamping processing multiple working procedure, working (machining) efficiency is high, machining accuracy is high。
The technical scheme is that, thering is provided a kind of knuckle shell drilling fixture with following structure, it includes base plate, the riser that is located on base plate, have the positioning core axle of tension, screw rod, two locating pieces for spacing knuckle housing being fixed on base plate and be positioned at screw rod both sides and be each provided at the first positioning plate assembly and second positioning plate assembly of base plate；Described positioning core axle is fixed on the medial wall of riser, and one end of described screw rod and the inner core of positioning core axle are fixed, and the outer end of described screw rod is removable is connected to a block pressur plate。
First positioning plate assembly and the second positioning plate assembly all include location-plate and fixing plate, described location-plate is provided with hole, multiple location, being provided with drill bushing in hole, described location, the top of the side of described location-plate and fixing plate joins, and both are provided with the fixing device of stationary positioned plate。
Described fixing device refers to, the top of described fixing plate is provided with two the first grooves, it is provided with spherical pit in each groove, in each spherical pit, bulb is connected to a bolt, described location-plate also is provided with two the second grooves, and described bolt can be embedded in second groove of correspondence and head outer diameter is more than the width of the second groove。
After adopting said structure, the present invention is compared with prior art, when having the advantage that clamping, knuckle housing is put in fixture, and by the cross spacing of two pieces of locating pieces, endoporus is nested on positioning core axle simultaneously, again pressing plate is inserted on screw rod, compressing with nut, while pressing plate moves inward, the clamping block of positioning core axle is protruding until offseting with the hole inwall of knuckle housing, fixes knuckle housing so from inside to outside。It is put into drilling machine and adds man-hour, first location-plate is turned to the top of knuckle housing, namely vertical with fixing plate, fix device both to be fixed simultaneously, then add and additionally need not bore locating and machining hole by centralized positioning again man-hour, but directly with bit bore, it is drilled hole, unclamp fixing device, then overturn location-plate outward, change tap tapping being originally drilled in hole, it is finally completed the processing of screwed hole, so disposable clamping can process multiple working procedure, need not adjust every time, calibrates, saving of work and time, and working (machining) efficiency is high；And because of the clamping through same pair of fixture, only needing a benchmark, so disposable clamping, machining accuracy is high。
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of the knuckle shell drilling fixture of the present invention。
As shown in the figure: 1, base plate, 2, riser, 3, positioning core axle, 4, screw rod, 5, locating piece, 6, location-plate, 6.1, hole, location, the 6.2, second groove, 7, fixing plate, the 7.1, first groove, 8, drill bushing, 9, bolt。
Detailed description of the invention
Below in conjunction with accompanying drawing, the invention will be further described。
As shown in Figure 1, the knuckle shell drilling fixture of the present invention, it includes base plate 1, the riser 2 being located on base plate 1, the positioning core axle 3 with tension, screw rod 4, two locating pieces 5 for spacing knuckle housing being fixed on base plate 1 and be positioned at screw rod 4 both sides and be each provided at the first positioning plate assembly and second positioning plate assembly of base plate 1；Described positioning core axle 3 is fixed on the medial wall of riser 2, one end of described screw rod 4 and the inner core of positioning core axle 3 are fixed, the outer end of described screw rod 4 is removable is connected to a block pressur plate, pressing plate just uses when clamping, do not reside at ordinary times on screw rod, also needing matching nut and pad clamping platen in use, the length of pressing plate is more than the internal diameter of the interior outer end of hole of knuckle housing。
First positioning plate assembly and the second positioning plate assembly all include location-plate 6 and fixing plate 7, described location-plate 6 is provided with hole, multiple location 6.1, being provided with drill bushing 8 in hole, described location 6.1, the top of the side of described location-plate 6 and fixing plate 7 joins, and both are provided with the fixing device of stationary positioned plate 6。
Described fixing device refers to, the top of described fixing plate 7 is provided with two the first grooves 7.1, it is provided with spherical pit in each groove, in each spherical pit, bulb is connected to a bolt 9, described location-plate 6 also is provided with two the second grooves 6.2, and described bolt 9 can be embedded in second groove 6.2 of correspondence and head outer diameter is more than the width of the second groove 6.2。
During clamping, knuckle housing is put in fixture, cross spacing by two pieces of locating pieces, endoporus is nested on positioning core axle simultaneously, again pressing plate is inserted on screw rod, compressing with nut, while pressing plate moves inward, the clamping block of positioning core axle is protruding until offseting with the hole inwall of knuckle housing, fixes knuckle housing so from inside to outside。It is put into drilling machine and adds man-hour, first location-plate is turned to the top of knuckle housing, namely vertical with fixing plate, fix device both to be fixed simultaneously, then add and additionally need not bore locating and machining hole by centralized positioning again man-hour, but directly with bit bore, it is drilled hole, unclamp fixing device, then overturn location-plate outward, change tap tapping being originally drilled in hole, it is finally completed the processing of screwed hole, so disposable clamping can process multiple working procedure, need not adjust every time, calibrates, saving of work and time, and working (machining) efficiency is high；And because of the clamping through same pair of fixture, only needing a benchmark, so disposable clamping, machining accuracy is high。
