Abstract
The utility model aims to overcome the defects that the prior machining process of oil grooves and chamfers on large-bore ends of connecting rods causes low production cost, inconvenience in operation, time and labor consumption and the like, and provides a tool unit for machining of connecting rods. The tool unit is characterized in that a grooving tool and a chamfering tool are integrated to the tool unit; accordingly, oil grooves and chamfers can be machined without changing tools.
Description
Technical field
The utility model relates to Machining of Connecting Rod field, specially refers to a kind of cutter hub assembly.
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 first on a milling machine, use groove cutter to process the oil groove of the first side of connecting rod macropore, then change rose reamer and complete the processing of homonymy chamfering; Second step: change another milling machine the oil groove of connecting rod macropore head opposite side is processed, then change rose reamer and complete the processing of chamfering.
Obviously, prior art is used the oil groove of milling machine to connecting rod macropore head side and the processing of chamfering, needs at least two milling machines, and production cost is high; And in process, need to change cutter, complex operation inconvenience, wastes time and energy.
Summary of the invention
In order to overcome in the process of the oil groove of prior art to connecting rod macropore head side and chamfering, the deficiency such as the production cost of existence is high, complex operation is inconvenient, waste time and energy, the utility model proposes a kind of Machining of Connecting Rod cutter hub assembly.
A kind of Machining of Connecting Rod of the utility model comprises cutter hub bar, rose reamer, spacer sleeve, groove cutter, fastening nut three with cutter hub assembly.Cutter hub bar is made up 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.
Further feature, rose reamer and groove cutter position exchange.
It is that groove cutter and rose reamer are incorporated on a toolbox that the utility model is created design, to realize the processing of not changing cutter and just realize respectively oil groove and chamfering.When the utility model is implemented, the Machining of Connecting Rod assembling is held on to the bare terminal end of lathe chuck with cutter hub assembly, knife rest place at lathe installs the Clamping Apparatus of Connecting Rod that has clamped connecting rod to be processed, after proofreading and correct well, can start lathe and carry out the processing of connecting rod groove and chamfering.
Aforementioned Clamping Apparatus of Connecting Rod comprises clamp bottom board, connecting rod macropore post and connecting rod small bore columns.Clamp bottom board is made up 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 angle α of the connecting rod macropore axis of a cylinder heart and connecting rod small bore columns axial connecting line and vertical curve is 20 °.
The beneficial effects of the utility model are, groove cutter and rose reamer are incorporated on a cutter hub assembly, in process, needn't change cutter, operate more easy, time saving and energy saving; Use a lathe that installs Machining of Connecting Rod cutter can realize oil groove and the chamfer machining to connecting rod both sides, reduced production cost.
