Description
Technical Field
The utility model belongs to the technical field of the measurement of machine-building, concretely relates to measuring device of spiral bevel gear crown distance, the online high-efficient detection of specially adapted spiral bevel gear crown distance.
Background
The crown pitch is the distance from the positioning surface of the spiral bevel gear to the intersection point of the crown surface cone and the axial bevel, is the reference for measuring the chord tooth height and the chord tooth thickness, and is an important item for control in the bevel gear machining process. However, the distance between the crown and the related surface and the distance between the crown and the related point are difficult to detect in actual processing, the existing detection adopts a three-coordinate detection device under a large molded line, the detection time is long, secondary clamping errors exist, and the processing efficiency and the product quality of the product are seriously influenced.
SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a measuring device of spiral bevel gear crown distance has improved detection efficiency greatly, has reduced latency and secondary clamping error.
The technical scheme of the utility model is that a measuring device for the crown pitch of a spiral bevel gear comprises a base body 1, a positioning block 3, an opening sleeve 4 and a locking bolt 2;
The deviation of the included angle of the two ends of the substrate 1 is plus or minus 15 degrees.
The utility model has the advantages that the utility model adopts the standard part dial indicator to realize the detection of the wheel crown distance, the structure is simple and reasonable, and the manufacturing cost is low; the operation is convenient, the online detection can be realized, and the secondary clamping error is reduced; the comparison and detection with the standard component are realized, and whether the processed product is qualified or not is more intuitive.
Drawings
Fig. 1 is a schematic structural view of a device for measuring a crown pitch of a helical bevel gear according to the present invention;
fig. 2 is a schematic structural diagram of the present invention in a measuring state.
Detailed Description
The technical solution of the present invention is described in detail below with reference to the drawings and examples of the specification.
As shown in fig. 1 and fig. 2, the device for measuring the crown pitch of the helical bevel gear of the present invention includes a base 1, a positioning block 3, an opening sleeve 4 and a locking bolt 2.
The base body 1 is of a bending structure, one end of the base body 1 is in a horizontal position, an included angle formed by two ends of the base body 1 is complementary with a bevel angle of a bevel gear to be measured, and deviation of the included angle is positive and negative 15 degrees. The positioning block 3 is a V-shaped positioning block, and a V-shaped groove and an upper surface A of the V-shaped positioning block are detection positioning surfaces. One end of the positioning block 3 is fixed on the horizontal end of the base body 1. The other end of the base body 1 is provided with a detection meter mounting hole, the opening sleeve 4 is arranged in the detection meter mounting hole, the locking bolt 2 is screwed on the end face of the other end of the base body 1, and the end face of the locking bolt 2 is propped against the periphery of the opening sleeve 4.
The base body 1 and the positioning block 3 can be connected by welding, the included angle of the V-shaped groove of the V-shaped positioning block is 90 degrees, the V-shaped groove is of an open structure, the length of the side edge of the V-shaped groove is not more than the diameter of the positioning circle, the bottom surface of the other end of the base body 1 is parallel to the surface cone of the part to be measured, the inclined plane is provided with a hole for fixing the gauge outfit, and the gauge needle is perpendicular to the surface of the part. The head of the locking bolt 2 is of a four-petal knurling structure, so that the manual locking is convenient and reliable.
The working principle of the utility model is that the base body 1 is mainly used for connecting the standard component, the dial indicator and the locking bolt 2, and the locking bolt 2 is mainly used for locking the dial indicator; in the practical use embodiment, the included angle of the V-shaped positioning block of the positioning block 3 is 90 degrees, the V-shaped groove and the upper surface A of the V-shaped positioning block are respectively matched with the positioning excircle and the positioning surface of the standard part, the standard part is rotated, the numerical value is read from the dial indicator, the measurement of the standard part is completed, the measurement of the measured part is completed in the same way, and the two groups of numerical values are compared to determine whether the measured part is qualified;
the utility model discloses utilize contrast method principle, detect the standard part earlier and detect the quilt again and surveyed the piece, confirm through gauge outfit reading contrast whether qualified by the quilt. And the online detection is realized by adopting an open structure.
