The utility model content
Technical problem to be solved in the utility model just provides a kind of motor rear end cover detection tool, and the screw hole of back end cover for motor is detected fast and accurately.
For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of motor rear end cover detection tool, it is characterized in that: comprise base, in-plane is provided with a circular end cap groove of placing back end cover for motor on the described base, the last plane of described base also is provided with the register pin of a level in the end cap groove outside, also intersect with the center line of end cap groove at the center of the screw hole of the axial line of described register pin by one of them standard of back end cover for motor, the plane is provided with several circular columns in end cap groove outer on the described base, and the line at the center, back end cover for motor standard screws hole that the center, upper surface of described column is corresponding with it and the center line of end cap groove intersect.
As preferably, described base is circular, and the center of described base overlaps with the center of end cap groove, described several columns to be centered close to the end cap groove center be on the concentric circles in the center of circle.
As preferably, the upper end of described column is that central shaft is provided with two symmetrical inclined-planes with the end face center line, and the center line of the extension line of described end face center line and described end cap groove intersects.Be convenient to the position of visual detection screw hole fast and accurately.
As preferably, described base sidepiece is fixed a riser, and described register pin passes riser and fastening by a screw.Described riser is anchored on described base sidepiece by a screw, and described register pin rear end is also by the fastening balanced handle of screw.Process and assemble is convenient.
As preferably, the upper edge of described end cap groove is provided with chamfering.Be convenient to place circular back end cover for motor.
As preferably, the center of described end cap groove is provided with a center pit.Be provided with a mark post in the described center pit, described mark post upper end is a taper, and the awl point of described mark post is concordant with the axial line of described register pin.Be convenient to range estimation.
The utility model is positioned over back end cover for motor in the end cap groove owing to adopted technique scheme, just can estimate the position of screw hole, and it is simple to operate that this detects frock, and only need use range estimation, fast and accurately.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is further described:
Fig. 1 is the back end cover for motor end view;
Fig. 2 is vertical view of the present utility model (a placement back end cover for motor);
Fig. 3 is the A-A cut-open view (not Electrical Discharge Machine rear end cap) of Fig. 2;
Fig. 4 is a kind of side view of column;
Fig. 5 is the side view of another kind of column.
Embodiment
Extremely shown in Figure 4 as Fig. 2, embodiment for a kind of motor rear end cover detection tool of the utility model, comprise base 1, in-plane is provided with a circular end cap groove 7 of placing back end cover for motor on the described base, the last plane of described base also is provided with the register pin 4 of a level in the end cap groove outside, also intersect with the center line of end cap groove at the center of the screw hole of the axial line of described register pin by one of them standard of back end cover for motor, the plane is provided with several circular columns 2 in end cap groove outer on the described base, and the line at the center, back end cover for motor standard screws hole that the center, upper surface of described column is corresponding with it and the center line of end cap groove intersect.Described base 1 is circular, and the center of described base overlaps with the center of end cap groove 7, described several columns to be centered close to the end cap groove center be on the concentric circles in the center of circle.The center of described end cap groove is provided with a center pit 10.Be provided with a mark post 11 in the described center pit, described mark post upper end is a taper, and the awl point of described mark post is concordant with the axial line of described register pin.The upper end of described column 2 is that central shaft is provided with two symmetrical inclined-planes 8 with end face center line 9, and the center line of the extension line of described end face center line and described end cap groove intersects.Described base 1 sidepiece is fixed a riser 3, and described register pin passes riser and fastening by a screw 6.Described riser is anchored on described base sidepiece by a screw, and described register pin rear end is also by the fastening balanced handle 5 of screw.The upper edge of described end cap groove 7 is provided with chamfering.
