The fixture bottom plate consists of a first bottom plate and a second bottom plate which are vertical to each other; the second bottom plate is provided with a bolt hole for being matched with a bolt to fix the fixture bottom plate on a lathe saddle; the connecting rod big bore log and the connecting rod small bore log are mounted at the same side of the first bottom plate; an included angle between the connecting line of the axle center of the connecting rod big bore log and the axle center of the connecting rod small bore log and the vertical line is alpha. The connecting rod fixture has the beneficial effect of overcoming the defects of high production cost, cumbersomeness and inconvenience for operation, easiness for deformation of a rod body of a connecting rod and the like in the prior art, which are caused by the case that a milling machine is used for machining an oil tank and a chamfer at the side of a connecting rod big hole head and a milling machine fixture is used for carrying out clamping.
Description
Technical field
The utility model relates to spare parts processing machinery field, specially refers to a kind of Clamping Apparatus of Connecting Rod.
Background technology
Connecting rod is that in linkage, two ends are hinged to transmit the rod member of motion and power with active and driven member respectively.It comprises eurypyloue macropore head and foraminate aperture head is set is set, and macropore head both sides are provided with oil groove and chamfering.Oil groove and the chamfer machining of prior art to connecting rod macropore head side, use be milling machine processing.This processing method mainly comprises following two steps, the first step: need the first oil groove processing to the first side of connecting rod macropore on a milling machine, then change the processing that rose reamer completes chamfering; Second step: change another milling machine the oil groove of connecting rod macropore head opposite side is processed, then change the processing that rose reamer completes chamfering.In process, use fraise jig to clamp.During due to milling machine processing and milling, cutting force is larger, is again interrupted cut, vibrate larger, so the connecting rod body of rod to bear torsional forces very large, easily cause occurring metaboly.
Obviously, prior art is used milling machine to the oil groove of connecting rod macropore head side and the processing of chamfering, needs at least two milling machines, and production cost is high; And in milling machine process, it is very large that connecting rod shank portion is born torsional forces, easily causes connection-rod body deformability.
Summary of the invention
In order to overcome prior art, use milling machine to the oil groove of connecting rod macropore head side and the processing of chamfering, use fraise jig to clamp, and the deficiency such as the production cost existing is high, complex operation is inconvenient, the connecting rod body of rod is yielding the utility model proposes a kind of Clamping Apparatus of Connecting Rod.
The utility model Clamping Apparatus of Connecting Rod comprises clamp bottom board, connecting rod macropore post and connecting rod small bore columns.Clamp bottom board is comprised of orthogonal the first base plate and the second base plate, is provided with bolt hole, for fitted bolt, clamp bottom board is fixed on to lathe saddle on the second base plate.Connecting rod macropore post and connecting rod small bore columns are arranged on the homonymy of the first base plate, and the angle of the connecting rod macropore axis of a cylinder heart and connecting rod small bore columns axial connecting line and vertical curve is α.
Further feature, α is 20 °.
Further feature, Clamping Apparatus of Connecting Rod also comprises connecting rod gland and screw rod.Screw rod is fixedly mounted on connecting rod macropore post front end, and connecting rod gland coordinates with screw flight, for the macropore head of connecting rod is pressed abd fixed on to the first base plate.
Further feature, is provided with circular-arc through hole on the first base plate of Clamping Apparatus of Connecting Rod, and fastening nut one and fastening nut two threaded engagement are at connecting rod small bore columns two ends, for the connecting rod small bore columns of inserting through hole is fixed on to the first base plate.
It is a kind of brand-new and more easy Clamping Apparatus of Connecting Rod of design that the utility model is created design, to realize, uses lathe to replace the processing of milling machine to the oil groove of connecting rod and chamfering.During concrete enforcement, the utility model Clamping Apparatus of Connecting Rod that has clamped connecting rod is fixed on lathe saddle, on lathe chuck, installs cutter hub assembly, then proofreaied and correct lathe and can start lathe and process.
Described cutter hub assembly comprises cutter hub bar, rose reamer, spacer sleeve, groove cutter and fastening nut three above.Cutter hub bar is comprised of integrated thick, thin two sections of straight-bars, and two sections of straight-bar connecting parts of thickness form the circular step face that is positioned at thick section of straight-bar.Rose reamer, spacer sleeve and groove cutter are run through by the thin segment straight-bar of cutter hub bar successively, and by being pressed abd fixed on the circular step face of thick section of straight-bar with the fastening nut three of thin segment straight-bar front end threaded engagement.
The beneficial effect of a kind of Clamping Apparatus of Connecting Rod of the utility model is to have been realized and used lathe to replace milling machine to process the oil groove of connecting rod and chamfering by this fixture.And use a chassis bed can realize the oil groove of connecting rod both sides and chamfer machining, reduced production cost; The angle of the connecting rod macropore axis of a cylinder heart and connecting rod small bore columns axial connecting line and vertical curve is α, and when α angle is 20 °, the torsional forces that in process, the connecting rod body of rod bears is minimum, and deformation least easily occurs the connecting rod body of rod.
