The coupling is characterized in that the spline shaft I (1) is a cover. The spline shaft II (2) is a shaft. A thread (7) is arranged in the middle of the gear shaft cavity I (1). A cone pin hole I (6) is arranged in front of the gear shaft cavity. A cone pin hole II (8) is arranged at the back end of the vertical direction. The adjusted pad (5) is arranged between the connection of the spline shaft I (1) and spline shaft II (2).
Description
Technical field
The utility model relates to the connection of special axial workpiece in a kind of field of machining, more specifically to the connection of the driving-rod between a kind of crank connecting rod journal lathe left side headstock and the right headstock.
Background technique
Crank connecting rod journal lathe is a special purpose machine tool, be mainly used in various eccentric shafts, rod journal turning processing, finish the processing of operations such as the filleted corner of the inner side surface of inner side surface, crank of crank-shaft link neck, crank and connecting rod neck intersection and the outer rounded corner of bent axle, thus crank connecting rod journal lathe require assembling and setting after left and right headstock spindle rotate synchronously.This shows that it is this lathe important component part that transmission shaft between the left and right headstock of crank connecting rod journal lathe connects, it requires transmitting torque big, and relative rotation is easy to adjust, and is not yielding.Placement between the left and right headstock of crank connecting rod journal lathe is more at present, and the employing tooth that has is to dental structure, and labor strength is big during this structure assembling, and is difficult to guarantee precision.But main now lead screw shaft, the splined shaft of adopting connects, but these special axial workpieces cause processing, transportation all inconvenient, and have problems such as assembly precision is not high owing to long.
The model utility content
The technical problems to be solved in the utility model is: overcome special axial workpieces such as lead screw shaft, splined shaft because long, cause processing, transportation is inconvenient and mechanical assembly process in precision not high, problems such as assembly technology complexity provide a kind of adjustable shaft coupling that can improve the crank connecting rod journal lathe precision.
The utility model comprises splined shaft I, splined shaft II, taper pin I, taper pin II, spacer, be characterized in: splined shaft I is cover, splined shaft II is an axle, in the middle of splined shaft I inner chamber, be provided with screw thread, the inner chamber front end is provided with circular cone pin-and-hole I, and intracavity posterior end and circular cone pin-and-hole I Vertical direction are provided with circular cone pin-and-hole II.Spacer is equipped with in splined shaft I and splined shaft II joint.Be respectively equipped with spiral chute on the front and back ends axle of splined shaft II and splined shaft I inner chamber mating part, be provided with screw thread in the middle of it.
The utility model has the advantages that: simple in structure, easy to operate, cost is low.Improved the crank connecting rod journal lathe transmission accuracy, made its stable performance, long service life, thus realization improves the machining accuracy of crank connecting rod journal lathe.Adjustable shaft coupling not only can be used for the connection of the driving-rod between the left and right headstock of crank connecting rod journal lathe, also can be widely used in the connection of special axial workpieces such as leading screw, splined shaft.
Description of drawings
Below in conjunction with accompanying drawing the utility model is described in further detail.
Fig. 1 is the structural representation of a kind of adjustable shaft coupling of the utility model;
Fig. 2 is the structural representation of splined shaft I1;
Fig. 3 be among Fig. 2 A-A to sectional view;
Fig. 4 is the plan view of splined shaft II2;
Fig. 5 is the plan view of Fig. 4.
Embodiment
In Fig. 1,2,3,4,5: splined shaft I1 is cover, and splined shaft II2 is an axle.Be provided with the ladder blind hole in splined shaft I1 inner chamber, be provided with screw thread 7 in the middle of it, the inner chamber front end is provided with circular cone pin-and-hole I6, and intracavity posterior end and circular cone pin-and-hole I6 Vertical direction are provided with circular cone pin-and-hole II8, its objective is to add strong fix.Spacer 5 is equipped with in splined shaft I1 and splined shaft II2 joint, and its effect is: realize the relative rotation of two coupling shafts by the thickness of match grinding spacer 5, crank connecting rod journal lathe is reached adjust the left and right headstock spindle in back and rotate synchronously.Splined shaft II2 and splined shaft I1 inner chamber mating part are set as multidiameter shaft, are respectively equipped with spiral chute 9,11 on its front and back ends axle, and effect is: deaeration.The centre is provided with screw thread 10, and effect is: be threaded with the screw thread 7 of splined shaft I1 inner chamber, be convenient to adjust.
The utility model is assembling like this: the splined shaft I1 inner chamber of at first splined shaft II2 being packed into, make the diaxon of its connection concentric, screw in the intermediate thread part again, after the left and right headstock spindle of crank connecting rod journal lathe satisfies requirement synchronously, accurately measure the distance of (debuging whole pad position) between two coupling shafts, the intermediate thread of outwarding winding then part makes splined shaft II2 separate with splined shaft I1.Again the spacer behind the match grinding 5 is packed on the splined shaft II2, with the splined shaft II2 splined shaft I1 inner chamber of packing into, tighten two coupling shaft helical thread portions, circular cone pin-and-hole I6 on the splined shaft I1 and the direction of circular cone pin-and-hole II8 respectively then, by splined shaft II2, bore the circular cone pin-and-hole, in circular cone pin-and-hole I6 and circular cone pin-and-hole II8, be respectively charged into taper pin I3 and taper pin II4 then, it is fixed in Vertical direction.
In sum, the utility model is to adopt the taper pin location, be threaded, realize the relative rotation of two coupling shafts by the thickness of match grinding spacer, synchronous to reach the main shaft of adjusting the left and right headstock in back, after satisfying the relative rotation requirement, fix in the relevant position with different taper pins, thus the machining accuracy of realization crank connecting rod journal lathe.
