Description
Technical field
The utility model relates to machine field, and the right alignment that relates in particular to a kind of electric motor end cap detects frock.
Background technology
The right alignment of electric motor end cap is meant the measurement of electric motor end cap iron core shelves inner headed face and bearing guard inner headed face right alignment, is the important essential items for inspection of electric motor end cap, and it is related to motor gas-gap, and motor gas-gap has determined the stability of motor quality.Electric motor end cap often adopts stamping parts at present; The bearing chamber of electric motor end cap is a blind hole structure; On lathe, can't carry out coaxality measurement, and thin-walled stretching end cap exists big ellipse and tapering with respect to metal processing end cap, carry out clamping with external diameter and measure with the endoporus clamping; Measuring error is bigger, and efficient is lower.Mostly adopt special-purpose receiver ga(u)ge to carry out the right alignment check at present, domestic indivedual strong enterprises adopt advanced three-coordinates measuring machine to measure; Measurement data is accurate, but the process of measuring is complicated, loaded down with trivial details, and efficient is low; Use inconvenience, because after electric motor end cap and the stator assembling, ovality can diminish; Therefore also exist measurement data qualified, the still underproof phenomenon of electric motor end cap occurs.
The utility model content
The utility model wants the technical solution problem to be: provide a kind of right alignment of electric motor end cap to detect frock, the right alignment of this kind electric motor end cap detects frock can not only guarantee that measurement result is accurate, and has improved detection efficiency.
Solve the problems of the technologies described above; The technical scheme of the utility model is: a kind of right alignment of electric motor end cap detects frock; It comprises the keeper of dial bore gage, measuring staff, gauge head, revolving part and solid of revolution; Described keeper has annular boss, first detection segment, second detection segment and revolving part mating holes, and described annular boss is between first detection segment and second detection segment, and the upper surface of described annular boss, the lower surface all center line with keeper are vertical; Described revolving part has the periphery that the revolving part mating holes with keeper adapts; Described measuring staff vertically passes revolving part, and described gauge head is positioned at the lower end of measuring staff, and described dial bore gage is positioned at the top of measuring staff.
Described revolving part cooperates section and keeper to cooperate the cylindrical section of section top to form by keeper; Described revolving part has plural measuring staff hole; The center line in each measuring staff hole is all parallel with the center line of revolving part; The cylindrical section of described revolving part is provided with the threaded hole that is communicated with respectively with each measuring staff hole, has holding screw in each threaded hole.
Described keeper is provided with the fabrication hole of being convenient to take.
The right alignment of the utility model electric motor end cap detects frock and adopts such structure, and is simple in structure, easy to operate, can guarantee that measurement result is accurate, improved detection efficiency.

Fig. 4 is that the right alignment of the utility model electric motor end cap detects frock user mode structural representation;
In Fig. 1, Fig. 2, Fig. 3, Fig. 4,1, keeper; 2, revolving part; 3, holding screw; 4, dial bore gage; 5, measuring staff; 6, side head; 7, first detection segment; 8, annular boss; 9, second detection segment; 10, revolving part mating holes; 11, measuring staff hole; 12, threaded hole; 13, cylindrical section; 14, keeper cooperates section; 15, electric motor end cap.
Embodiment
Like Fig. 1, Fig. 2, Fig. 3, shown in Figure 4; The right alignment of electric motor end cap detects the keeper 1 that frock comprises dial bore gage 4, measuring staff 5, gauge head 6, revolving part 2 and solid of revolution; Keeper 1 has annular boss 8, first detection segment 7, second detection segment 9 and revolving part mating holes 10; Annular boss 8 is between first detection segment 7 and second detection segment 9; The upper surface of annular boss 8, the lower surface all center line with keeper 1 are vertical, have the fabrication hole of being convenient to take on the keeper, and the diameter of fabrication hole answers handled easily worker finger to stretch into.
Revolving part 2 has the periphery that the revolving part mating holes with keeper 1 adapts, and measuring staff 5 vertically passes revolving part 2, and gauge head 6 is positioned at the lower end of measuring staff 5, and dial bore gage 4 is positioned at the top of measuring staff 5.Revolving part cooperates section 14 and keeper to cooperate the cylindrical section 13 of section 14 tops to form by keeper; Revolving part 2 has plural measuring staff hole 11; The center line in each measuring staff hole 11 is all parallel with the center line of revolving part 2; Have the threaded hole 12 that is communicated with respectively with each measuring staff hole 11 on the cylindrical section 13 of revolving part, have holding screw 3 in each threaded hole 12.
Keeper the upper and lower end face on be carved with the reference dimension and the tolerance of second detection segment, first detection segment respectively, according to the difference of circle tolerance in the electric motor end cap, select first detection segment or second detection segment of keeper during detection.Internal diameter according to the electric motor end cap bearing chamber; Select the measuring staff hole of revolving part, the measuring staff of dial bore gage is passed the measuring staff hole of rotating mechanism, install gauge head; Adjust dial bore gage, through threaded hole dial bore gage and revolving part are fixed as one perpendicular to the measuring staff hole with trip bolt.During use, rotate revolving part, the jerk value of dial bore gage just demonstrates electric motor end cap iron core shelves inner headed face and bearing guard inner headed face right alignment.
The right alignment of the utility model electric motor end cap detects frock and adopts such structure, and is simple in structure, easy to operate; Be applicable to and produce online detection, also can be used for batch detection, state is similar during with actual use the in electric motor end cap assembling back; Avoided measurement data qualified, the underproof phenomenon of electric motor end cap occurs, and can guarantee that measurement result is accurate; Improve detection efficiency, reduce cost of manufacture and detect cost.
