Abstract
The utility model relates to a cutting and positioning tool for a crank shaft. The cutting and positioning tool comprises a bottom board, wherein a U-shaped lug boss is arranged on the bottom board; mounting holes are formed in the bottom and the lateral walls of a U-shaped groove in the middle of the lug boss; steel sleeves are respectively mounted inside the mounting holes; adjustment nuts are mounted inside the mounting holes in the lateral walls; the crank shaft is mounted inside the mounting hole at the bottom; the tops of the adjustment nuts are abutted against a table face of the top of the crank shaft. The cutting and positioning tool has the advantages of simple structure, flexibility and convenience in use, high machining efficiency and easiness of guaranteeing the precision.
Description
Technical field
The utility model relates to technical field of tooling clamps, relates in particular to a kind ofly for crank axle, to 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 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.
Utility model content
The utility model, for above-mentioned shortcoming of the prior art, provides a kind of crank axis cutting positioning tool, and it is simple in structure, flexible and convenient to use, and working (machining) efficiency is high, and precision easily guarantees.
The technical scheme that the utility model adopts 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 copper sheathing are threaded engagement.
The utility model has the advantage of: U-shaped boss is set on base plate and forms U-lag, crank axle is fixed in U-lag by copper sheathing, by the precision-fit of the equal copper sheathing of simple nut, realize the clamping location to 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 utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present utility model is described.
As shown in Figure 1, the utility model comprises 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 utility model 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 to explanation of the present utility model, is not the restriction to utility model, and the utility model limited range, referring to claim, within protection domain of the present utility model, can be done any type of modification.
