Description
Technical field
The present invention relates to clamp technology field, is specifically a kind of knuckle shell drilling fixture.
Background technology
The blank of spindle housing need to be processed a plurality of screwed holes at top, generally need to first process locating hole at present, drill through Kong Zaiyong tap tapping.So, need three to operation; At fixture, add man-hour, to every one manufacturing procedure, need to prepare different fixture clampings, cannot be general, and each adjustment, calibration, time-consuming, finally affect working (machining) efficiency; And because the clamping of the different fixtures of process, each procedure need to be selected a datum level or a locating hole, and multiple clamping, affects final machining accuracy like this.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of disposable clamping processing multiple working procedure, working (machining) efficiency is high, machining accuracy is high knuckle shell drilling fixture are provided.
Technical scheme of the present invention is, a kind of knuckle shell drilling fixture with following structure is provided, and it comprises base plate, is located at the riser on base plate, the positioning core axle with tensioning, screw rod, be fixed on two locating pieces for spacing knuckle housing on base plate and be positioned at screw rod both sides and be all located at the first positioning plate assembly and second positioning plate assembly of base plate; Described positioning core axle is fixed on the madial wall of riser, and one end of described screw rod and the inner core of positioning core axle are fixed, the removable block pressur plate that is connected with in outer end of described screw rod.
The first positioning plate assembly and the second positioning plate assembly include location-plate and fixed head, described location-plate is provided with a plurality of locating holes, in described locating hole, be provided with drill bushing, a side of described location-plate and the handing-over of the top of fixed head, and both are provided with the fixture of stationary positioned plate.
Described fixture refers to, the top of described fixed head is provided with two the first grooves, in each groove, be provided with spherical pit, in each spherical pit, bulb is connected with a bolt, described location-plate is also provided with two the second grooves, and described bolt can be embedded in corresponding second groove and head outer diameter is greater than the width of the second groove.
Adopt after said structure, the present invention compared with prior art, have the following advantages: during clamping, knuckle housing is put in fixture, and by the cross spacing of two locating pieces, endoporus is nested on positioning core axle simultaneously, again pressing plate is inserted on screw rod, with nut, compress, when pressing plate moves inward, the clamping block of positioning core axle is protruding until offset with the hole inwall of knuckle housing, fixes so from inside to outside knuckle housing.Be put into drilling machine and add man-hour, first location-plate is turned to the top of knuckle housing, vertical with fixed head, fixture is fixed both simultaneously, then add and need not additionally by centralized positioning, bore processing locating hole again man-hour, but directly use bit bore, bored hole, unclamp fixture, then the location-plate that overturns outward, in the good hole of former subdrilling, change tap tapping, finally complete the processing of screwed hole, disposable like this clamping can be processed multiple working procedure, need not adjust, calibration, saving of work and time at every turn, and working (machining) efficiency is high; And because the clamping of same pair of fixture of process only needs a benchmark, disposable like this clamping, machining accuracy is high.
Accompanying drawing explanation
Accompanying drawing 1 is the schematic diagram of 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, locating hole, the 6.2, second groove, 7, fixed head, the 7.1, first groove, 8, drill bushing, 9, bolt.
The specific embodiment
Below in conjunction with accompanying drawing, the invention will be further described.
As shown in Figure 1, knuckle shell drilling fixture of the present invention, it comprises base plate 1, is located at the riser 2 on base plate 1, the positioning core axle 3 with tensioning, screw rod 4, be fixed on two locating pieces 5 for spacing knuckle housing on base plate 1 and be positioned at screw rod 4 both sides and be all located at the first positioning plate assembly and second positioning plate assembly of base plate 1; Described positioning core axle 3 is fixed on the madial wall of riser 2, the inner core of one end of described screw rod 4 and positioning core axle 3 is fixed, the removable block pressur plate that is connected with in outer end of described screw rod 4, pressing plate just uses when clamping, be not arranged on screw rod at ordinary times, also need in use matching nut and pad clamping platen, the length of pressing plate is greater than the internal diameter of the interior outer end of hole of knuckle housing.
The first positioning plate assembly and the second positioning plate assembly include location-plate 6 and fixed head 7, described location-plate 6 is provided with a plurality of locating holes 6.1, in described locating hole 6.1, be provided with drill bushing 8, one side of described location-plate 6 and the handing-over of the top of fixed head 7, and both are provided with the fixture of stationary positioned plate 6.
Described fixture refers to, the top of described fixed head 7 is provided with two the first grooves 7.1, in each groove, be provided with spherical pit, in each spherical pit, bulb is connected with a bolt 9, described location-plate 6 is also provided with two the second grooves 6.2, and described bolt 9 can be embedded in corresponding second groove 6.2 and head outer diameter is greater than the width of the second groove 6.1.
