Abstract
The utility model discloses a detection device for crankshaft circular run-out test, which is provided with a benchmark inspection shaft, wherein the external diameter of the benchmark inspection shaft is consistent with the external diameter of an actual main journal, and the benchmark inspection shaft is also provided with a positioning bolt for fixing the angular benchmark in the circumferential direction; the left end and the right end of the reference detection shaft are provided with indexing plates for detecting jumping, a center hole is formed in the center of each indexing plate, and a quick-change bolt is arranged in each center hole; the both ends that the axle was examined to the benchmark set up a pair of top, the utility model has the advantages that: the two-end basic positioning reference of the process inspection shaft can be protected, the two-end processing reference of the main shaft is further ensured, and the index plate and the angular positioning reference are arranged for detecting the jumping quantity in a specific direction.
Description
Technical Field
The utility model relates to a machine-building field, a positioner of technology datum axis specifically says so.
Background
In the prior art, because the main shaft belongs to a precise part and needs to calibrate the positions of the central holes at the two ends of the main shaft, the two ends of the process inspection shaft need to be calibrated firstly, so that the precise position of the central hole is ensured, and the two ends of the process inspection shaft also need to have the function of detecting circular runout.
SUMMERY OF THE UTILITY MODEL
In order to solve the problem, the utility model discloses a detection device for bent axle circle is beated and is tested.
The specific technical scheme is as follows:
a detection device for testing circular run-out of a crankshaft is provided with a reference detection shaft, wherein the outer diameter of the reference detection shaft is consistent with the outer diameter of an actual main journal, and a positioning bolt for fixing an angular reference is further arranged on the reference detection shaft in the circumferential direction; the left end and the right end of the reference detection shaft are provided with indexing plates for detecting jumping, a center hole is formed in the center of each indexing plate, and a quick-change bolt is arranged in each center hole; and a pair of apexes are arranged at two ends of the reference detection shaft.
Positions with different sizes are arranged at the left and the right of the reference detection shaft and used for distinguishing the front and the back of the reference detection shaft.
The utility model has the advantages that: the two-end basic positioning reference of the process inspection shaft can be protected, the two-end processing reference of the main shaft is further ensured, and the index plate and the angular positioning reference are arranged for detecting the jumping amount in a specific direction.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a left side view of fig. 1.
Detailed Description
The utility model is described in detail with the following drawings, as shown in the figures, a detection device for crankshaft circular run-out test is provided with a benchmark detection shaft 1, the external diameter of the benchmark detection shaft is consistent with the external diameter of an actual main journal, and the benchmark detection shaft is also provided with a positioning bolt 2 for fixing an angular benchmark in the circumferential direction; the left end and the right end of the reference detection shaft are provided with indexing disks 3 for detecting jumping, the center of each indexing disk is provided with a center hole 4, and a quick-change bolt 5 is arranged in each center hole; and a pair of apexes 6 are arranged at two ends of the reference detection shaft.
The utility model discloses a theory of operation is: firstly, two quick-change bolts are screwed on a reference detection shaft, then the quick-change bolts are placed on a pair of centers, the centers punch the quick-change bolts on the reference detection shaft, meanwhile, the positioning bolts and the index plate are matched, the reference detection shaft is rotated to detect the jumping amount of the quick-change bolts, if the jumping amount does not meet the requirement, the quick-change bolts are replaced, a new group of quick-change bolts are assembled again and placed on the centers, and the jumping amount meets the requirement.
