Abstract
The utility model discloses a kind of assembly type roll flute plug, comprise: plug body, axle head block, round nut stop washer, round nut, gland and nut, adopt interference fit between axle head block and plug body, axle head block left end adopts round nut and round nut stop washer to realize axial location; Treat that the workpiece of roll flute is enclosed within plug body, treat that one end axle head block of the workpiece of roll flute blocks, treat that the other end of the workpiece of roll flute is pushed down by gland and adopts fastening nuts.After the utility model uses this roll flute plug, internal spline and the exigent part of external gear axiality can be processed, improve operating efficiency, reduce the disqualification rate of part, reduce production cost.
Description
Technical field
The utility model relates to a kind of assembly type roll flute plug.
Background technology
At present, in some engineering machinery, mostly numerous parts is to connect to come transmitting torque with involute spline, and cylindrical hole was felt relieved with coordinating of axle, ensured mechanically operated precision and stationarity.Some parts are wherein because reasons in structure can only come transmitting torque and centering with spline joint, in machine driving, spline joint is mainly used for torsion pass, want to realize centering requirement, just must improve the machining accuracy of internal spline, also will improve the form and position tolerance between spline and pitch circle simultaneously.But, due to the deficiency of machining accuracy, fit clearance between spline is excessive, internal spline and gear form and position tolerance overproof, thus reduce mechanically operated precision, cause the contact surface between gear teeth face bad, stand under load is uneven, vibration in gear operation process and the generation of noise, greatly reduce product quality and service life.
Utility model content
The purpose of this utility model is to provide a kind of assembly type roll flute plug.
For achieving the above object, the utility model by the following technical solutions:
A kind of assembly type roll flute of the utility model plug, comprise: plug body, axle head block, round nut stop washer, round nut, gland and nut, adopt interference fit between axle head block and plug body, axle head block left end adopts round nut and round nut stop washer to realize axial location; Treat that the workpiece of roll flute is enclosed within plug body, treat that one end axle head block of the workpiece of roll flute blocks, treat that the other end of the workpiece of roll flute is pushed down by gland and adopts fastening nuts.
Location spline grinding accuracy on described plug body reaches 4H GB/T 3478.1-2008, and described location spline is with tapering and pitch circle and plug body two ends centre bore axiality.
After the utility model uses this roll flute plug, internal spline and the exigent part of external gear axiality can be processed, improve operating efficiency, reduce the disqualification rate of part, reduce production cost.
Accompanying drawing explanation
Fig. 1 is the utility model general frame figure.
General frame figure when Fig. 2 is utility model works.
Detailed description of the invention
Details are as follows in conjunction with legend for a specific embodiment of the present utility model:
As depicted in figs. 1 and 2, a kind of assembly type roll flute plug, comprise: plug body 1, axle head block 2, round nut stop washer 3, round nut 4, gland 6 and nut 7, adopt interference fit between axle head block 2 and plug body 1, axle head block 2 left end adopts round nut 4 and round nut stop washer 3 to realize axial location; Treat that the workpiece 5 of roll flute is enclosed within plug body 1, treat that the location end face 9 of one end axle head block 2 of the workpiece 5 of roll flute blocks, treat that the other end of the workpiece 5 of roll flute is pushed down by gland 6 and adopts nut 7 fastening.
8 location splines,
Workpiece with internal spline and external gear is commonplace, and the workpiece internal spline of the type and the processing sequence of external gear are generally:
1, with endoporus and end face for benchmark grinds external gear;
2, be that benchmark inserts internal spline with endoporus with end face.
From process route, processing external tooth is all unified with the technological datum of processing internal spline, but still there is clamping error and correction error between two procedures, adopt general process route to be difficult to meet the designing requirement of drawing for the workpiece that requirement on machining accuracy is high.Now just need a kind of new operation route to meet the designing requirement of drawing.
A kind of assembly type roll flute of the present invention plug ensure that the manufacture requirements of drawing from technique, use this roll flute plug aft-loaded airfoil order to become:
1, be that benchmark inserts internal spline with endoporus with end face;
2, serial core rod with the internal spline processed and end face for benchmark removes roll flute.
Being a little of this process route, the processing of external gear is directly relevant to internal spline, does not need using endoporus as a transition baseline, directly avoids the mismachining tolerance adopting transition baseline to cause.
Implementation procedure of the present invention and result:
A kind of assembly type roll flute of the present invention plug is made up of 6 basic parts: plug body 1, axle head block 2, round nut stop washer 3, round nut 4, gland 6, nut 7, adopt interference fit between axle head block 2 and plug 1, axle head block 2 left end adopts round nut 4 and round nut stop washer 3 realize axial location and have anti-loosing effect.Before plug assembling, the spline on plug body 1 is through grinding, and precision reaches 4H GB/T 3478.1-2008 and locates spline 8 with tapering, and grinding ensure that location spline 8 pitch circle and plug body two ends centre bore axiality.In order to the rigging error produced when eliminating assembling, after plug assembling, upper grinding machine is by the location end face 8 of core grinding rod.During use, only need will treat that the workpiece of roll flute is enclosed within the spline 8 of location, internal spline now on workpiece is located automatically with the location spline 8 of band tapering, because namely external splines locates the spline that spline 8 is band taperings on plug body, so the cooperation of interior external splines can reach without sideshake, workpiece right-hand member just can carry out roll flute processing to workpiece after joining gland 6, nut 7.
It is more than a specific embodiment of the present utility model; detailed elaboration has been carried out to general principle of the present utility model and principal character; do not departing under scope of the present utility model and real situation, the change do the utility model and change still belong to protection domain of the present utility model.
