Description
Technical Field
The utility model belongs to the technical field of motor measuring tool, concretely relates to motor end cover keeps off measuring device for ring groove.
Background
In the field of motor manufacturing, for a motor without a bearing inner cover, in order to solve the problem of axial movement, a retainer ring groove for a hole is added in an end cover bearing chamber, a bearing retainer ring is installed during assembly, and in the actual production process, because the groove of the retainer ring groove is narrow and small, a special measuring tool is not provided, and when the traditional measuring tool is used for measuring, the error is large, the size of the machined retainer ring groove cannot meet the requirement, and inconvenience is caused for production and inspection.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide a measuring device is used in motor end cover retainer ring groove, solve the inconvenient, big scheduling technical problem of measuring error of operation that current measuring tool exists.
In order to solve the above problem, the technical scheme of the utility model is that: a measuring device for a retaining ring groove of a motor end cover is characterized in that the retaining ring groove is arranged in the circumferential direction of the upper part of the side wall of a bearing chamber of the motor end cover, and comprises a measuring circular table and a handheld rod vertically arranged in the middle of the top surface of the circular table;
the measuring circular table is of a cylindrical structure, and the diameter of the measuring circular table is the same as that of the inner cavity of the bearing chamber; the height dimension of the measuring circular truncated cone is the same as the distance dimension between the top edge of the retainer ring groove and the bottom surface of the bearing chamber;
one side of the top surface of the measuring round platform is recessed downwards to form a step surface, and the distance between the top surface of the measuring round platform and the step surface is the same as the width of the retainer ring groove.
The utility model adopts the above technical scheme, it utilizes the measuring tool of different size of a dimension to measure corresponding specification and dimension's fender ring groove, can realize keeping off ring groove size rapid survey to the motor end cover, has overcome the defect that current measuring method speed is slow and the error is big. Compared with the prior art, the utility model has the advantages of overall structure is simple reasonable, preparation simple process, installation and convenient operation, detection range are wide, detection speed is fast, the accuracy is high, productivity ratio is high.
Drawings
Fig. 1 is a schematic structural view of the present invention;
FIG. 2 is a top view of FIG. 1;
fig. 3 is a schematic view of the working state of the present invention.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples.
As shown in fig. 1 to 3, the measuring device for the motor end cover retainer groove is characterized in that the retainer groove 3 is arranged in the circumferential direction of the upper part of the side wall of the motor end cover bearing chamber, wherein: comprises a measuring circular truncated cone 1 and a hand-held rod 2 vertically arranged in the middle of the top surface 1 of the circular truncated cone;
the measuring circular table 1 is of a cylindrical structure, and the diameter of the measuring circular table 1 is the same as that of the inner cavity of the bearing chamber; the height dimension of the measuring circular truncated cone 1 is the same as the distance dimension between the top edge of the retainer ring groove 3 and the bottom surface of the bearing chamber;
one side of the top surface of the measuring round platform 1 is provided with a step surface 4 in a downward concave mode, and the distance between the top surface of the measuring round platform 1 and the step surface 4 is the same as the width of the retainer ring groove 3.
The utility model discloses a working process and principle:
manufacturing measuring tools with corresponding specifications according to the size of the end cover bearing chamber, such as phi 80,
Etc.; when the measuring device is used, the hand-held rod 2 is held by hand, the measuring circular truncated cone 1 is placed into a motor end cover bearing chamber to be measured, the motor end cover bearing chamber slowly rotates for a circle, whether the step surface 4 is parallel and level with the bottom edge of the retainer groove 3 or not and whether the top surface of the measuring circular truncated cone 1 is parallel and level with the top edge of the retainer groove 3 or not are checked, and therefore whether the measured retainer groove 3 meets the drawing requirements or not is judged.
