A kind of fixture that bores bent axle shoulder inclined oil hole of air, it is characterized in that, comprise workpiece erecting bed, this workpiece erecting bed upper surface is provided with the first back-up block, the second back-up block, the 3rd back-up block and support pin, described the first back-up block is provided with tapped through hole, by this tapped through hole threaded engagement, screw rod is installed, on described the second back-up block, be provided with the first circle arc support face, on described the 3rd back-up block, be provided with the second circle arc support face, described the first circle arc support face and the second circle arc support face are all positioned on same arc-plane, on described the second back-up block, be provided with the through hole that fluted drill passes, this through hole runs through the lateral surface of described the first circle arc support face and the second back-up block, between described the second back-up block and the 3rd back-up block, described support pin is set, this support pin is positioned under described screw front end.
Described spiro rod rear end is provided with turning handle, and described screw front end is provided with to the inclined-plane of described turning handle direction inclination.
The beneficial effects of the utility model:
Brill of the present utility model bores the fixture of bent axle shoulder inclined oil hole of air, relies on the second back-up block, the 3rd back-up block and support pin to form three fulcrums, and clamping screw compresses bent axle, realizes the fixing of bent axle.The simple cost of this clamp structure is low, and mechanical breakdown is few and to take, put crankshaft workpiece all simple and efficient.
Clamping screw front end is provided with to the inclined-plane of described turning handle direction inclination, and bent axle is subject to being applied to the extruding force under deflection, is convenient to bent axle and is fixed on fixture.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.
As shown in Figure 1, a kind of fixture that bores bent axle shoulder inclined oil hole of air, comprise workpiece erecting bed 1, this workpiece erecting bed 1 upper surface is provided with the first back-up block 2, the second back-up block 3, the 3rd back-up block 4 and support pin 5, described the first back-up block 2 is provided with tapped through hole, by this tapped through hole threaded engagement, screw rod 6 is installed, on described the second back-up block 3, be provided with the first circle arc support face 7, on described the 3rd back-up block 4, be provided with the second circle arc support face 9, described the first circle arc support face 7 and the second circle arc support face 9 are all positioned on same arc-plane, on described the second back-up block 3, be provided with the through hole that fluted drill passes, this through hole runs through the lateral surface of described the first circle arc support face 7 and the second back-up block 3, between described the second back-up block 3 and the 3rd back-up block 4, described support pin 5 is set, this support pin 5 is positioned under described screw rod 6 front ends.
Described screw rod 6 rear ends are provided with turning handle 10, and described screw rod 6 front ends are provided with to the inclined-plane of described turning handle 10 directions inclinations.
On workpiece erecting bed 1, there are three back-up blocks, on the first back-up block 2, there is tapped through hole, by this tapped through hole threaded engagement, clamping screw 6 is installed, on the second back-up block 3, be provided with the first circle arc support face 7, on the 3rd back-up block 3, be provided with the second circle arc support face 9, the first circle arc support face and the second circle arc support face are positioned on same arc-plane, on erecting bed, being also provided with support pin 5 is positioned under described screw front end, bent axle is positioned on the first circle arc support face 7 and the second circle arc support face 9 and support pin 5 of the second back-up block 2 and the 3rd back-up block 3, form the support of stable triangular.Clamping screw 6 rear ends are provided with turning handle 10, front end is provided with to the inclined-plane of described turning handle 10 directions inclinations, turning handle advances clamping screw 6, the inclined-plane of clamping screw 6 front ends can better fit bent axle arc surface and be fixed, finally by the fluted drill through hole on the second back-up block 3, bent axle is punched.
Brill of the present utility model bores the fixture of bent axle shoulder inclined oil hole of air, relies on the second back-up block 3, the 3rd back-up block 4 and support pin 5 to form three fulcrums, and clamping screw 5 compresses bent axle, realizes the fixing of bent axle.The simple cost of this clamp structure is low, and mechanical breakdown is few and to take, put crankshaft workpiece all simple and efficient.
