Abstract
The invention relates to a wire-cutting positioning tool of a crank shaft. The wire-cutting positioning tool of the crank shaft comprises a base plate, wherein the base plate is provided with a U-shaped boss, the bottom and the side walls of a U-shaped groove in the middle of the boss are respectively provided with a mounting hole, a steel bushing is mounted in one mounting hole, adjusting screw nuts are mounted in the mounting holes of the side walls of the U-shaped groove, the crank shaft is mounted in the bottom mounting hole, and the tops of the adjusting screw nuts abut against a table top on the top of the crank shaft. The wire-cutting positioning tool of the crank shaft is simple in structure, flexible and convenient to use, high in working efficiency, and capable of guaranteeing precision easily.
Description
Technical field
The present invention relates to technical field of tooling clamps, relate in particular to and a kind ofly for crank axle, carry out the positioner that mounting hole tangent line cuts.
Background technology
Although crank axle workpiece is relatively simple for structure, machine tool all can carry out various millings to it, the processing such as brill, but for the higher situation of required precision, also higher to the requirement of frock clamp, must use special-purpose its machining accuracy of frock guarantee, especially carrying out the special man-hour that adds, during as the line cutting processing of mounting hole, more to guarantee its precision, also will guarantee working (machining) efficiency simultaneously.
Summary of the invention
The present invention is directed to above-mentioned shortcoming of the prior art, a kind of crank axis cutting positioning tool is provided, it is simple in structure, flexible and convenient to use, and working (machining) efficiency is high, and precision easily guarantees.
The technical solution adopted in the present invention is as follows:
Crank axis cutting positioning tool, comprise base plate, on base plate with U-shaped boss, U-lag bottom in the middle of boss and sidewall are all with installing hole, steel bushing is housed respectively in described installing hole, in installing hole on described sidewall, adjusting nut is installed, crank axle is installed in the installing hole of described bottom, the table top at crank axle top is withstood at adjusting nut top;
Further technical scheme is as follows:
Described adjusting nut and steel bushing are threaded engagement.
The invention has the advantages that: U-shaped boss is set on base plate and forms U-lag, crank axle is fixed in U-lag by steel bushing, precision-fit realization by the equal steel bushing of simple nut is located the clamping of crank axle one end, and then its other end cylinder is carried out to line cutting processing, simple in structure, easy to setup, efficiency is high, and precision easily guarantees.
Accompanying drawing explanation
Fig. 1 is use state diagram of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
As shown in Figure 1, the present invention includes base plate 1, on base plate 1 with U-shaped boss 2, U-lag bottom in the middle of boss 2 and sidewall are all with installing hole, steel bushing 4 is housed respectively in described installing hole, adjusting nut 3 is installed in the installing hole on described sidewall, adjusting nut 3 adopts threaded engagement with steel bushing 4, be conducive to control its feeding adjusting precision, crank axle 5 is installed in the installing hole of described bottom, the table top at crank axle 5 tops is withstood at adjusting nut 3 tops, and steel bushing 4 adopts matched in clearance with crank axle 5, the dismounting after convenient processing;
Using method of the present invention is as follows:
The first step, is anchored on base plate 1 on workbench together with U-shaped boss 2;
Second step is put into respectively steel bushing 4 in the installing hole of U-lag bottom and sidewall;
The 3rd step, packs adjusting nut 3 in the steel bushing 4 in described U-lag sidewall installing hole into;
The 4th step, packs crank axle 5 in the steel bushing 4 in the installing hole of described U-lag bottom into;
The 5th step, adjusts adjusting nut 3, and its end is clamped it from crank axle 5 both sides;
The 6th step, detects crank axle 5 and stretches into one end end face and base plate 1 and the perpendicularity in described U-lag;
The 7th step, stretches out one end cylindrical line cutting mounting hole outside described U-lag to crank axle 5.
More than describing is explanation of the invention, is not the restriction to invention, and limited range of the present invention, referring to claim, within protection scope of the present invention, can be done any type of modification.
