Detailed Description
The technical solution of the present invention is further specifically described below by way of specific embodiments and with reference to the accompanying drawings.
Example 1
As shown in fig. 1 and 2, the tool for inspecting a double-ended bevel gear includes:
the base 1 is a disc-shaped flat plate, a mounting hole is formed in the middle of the base, an arc groove is concentrically formed along the mounting hole, the radius of an inner ring of the arc groove is smaller than that of the mandrel 2, and the radius of an outer ring of the arc groove is larger than that of the mandrel 2;
the mandrel 2 is cylindrical and is divided into two parts: the outer diameter of the upper side part is matched with that of the detection gear, the upper edge is provided with a lead-in groove, the lead-in groove and the top surface are in fillet transition, the lower side part and the upper side part are integrally formed, the inner diameters of the lower side part and the upper side part are the same, and the outer diameter of the lower side part is matched with the size of the mounting hole;
and the upper cover 4 is formed by rotating a T-shaped top edge as a shaft and is divided into three parts, the outer diameter of the lower part is matched with the inner diameter of the mandrel 2, the outer diameter of the middle part is larger than that of the detection gear, and the upper part and the lower part are symmetrical about the radial plane of the middle part.
The diameter of the end part and the tail part of the lower side part of the upper cover 4 is reduced during processing, the lower side part is matched with the inner diameter of the mandrel 2 through the middle section, the abrasion of the lower side part during the insertion of the mandrel 2 can be effectively reduced, and the lower side part is easier to process into a conical surface due to the segmented processing, so that the manufacturing is convenient.
The lower side part and the upper side part of the mandrel 2 are intersected and provided with matching grooves for reducing friction between the mandrel 2 and the base 1, and the corresponding position of the base 1 adopts a fillet to be excessive.
As shown in figure 1, the part 3 to be detected is a double-end-face gear with 3-degree taper angles on both end faces and a nominal size of 45.8 distance between the two taper angles at the diameter phi 70.
The cone height is detected using three coordinates as shown in fig. 2. The base 1 detects the distance from the nominal point (3-degree taper angle, phi 70 diameter intersection point) to the measuring reference surface, and the upper cover 4 detects the distance from the nominal point to the measuring surface, so that H1 and H2 numerical values are obtained. The value obtained by subtracting H2 from H1 is imprinted on the gauge as the base value. After the part 3 to be detected is placed in the mandrel 2, the upper cover 4 is covered, and after the part is aligned, the digital display height gauge can be used, the measuring head moves to the measuring surface by taking the measuring reference surface as a '0' point, and the numerical value H3 is read. And subtracting the basic value on the checking fixture from the H3 value to obtain the distance between the nominal points of the double-end-face cone.
The lower side surface of the middle part of the upper cover 4 is also provided with an arc groove, the outer diameter is matched with the outer diameter of the arc groove, and the inner diameter of the arc groove is smaller than the outer diameter of the arc groove, so that the degree of abrasion of two sides of the detected part 3 is reduced.
