Abstract
The invention discloses a machining process for symmetric key grooves of motor shaft extension and a fixture for the same. An alignment plate is locked on a screw hole, the bouncing distance between an upper plane and a lower plane of the alignment plate is controlled to be smaller than or equal to 0.03mm in tool setting, and then tools are set for milling the grooves. Without changing a product structure, an angle between the two symmetric key grooves of a motor shaft is indirectly detected by fixing the alignment plate onto an end face of the shaft and metering the upper plane of the alignment plate through a dial indicator, so that alignment accuracy and machining efficiency are improved, and the fixture is convenient in operation, high in precision and high in universality.
Description
Technical field
The present invention relates to a part processing technique field, especially motor shaft extension symmetry keyway processing technology and anchor clamps.
Background technology
In order to increase the transmission moment of torsion, part motor shaft extension place need adopt the symmetric double keyway, adds man-hour if two keyway symmetries are overproof, then can cause the both sides keyway can not be simultaneously stressed, thereby influence the transmission effect of moment of torsion, therefore needs the assurance machining accuracy.When motor shaft was heavier, it was uneconomic using special purpose machine tool to process symmetrical keyway, and on common boring and milling machine, adds man-hour; If carry out centering with a manufactured side switch groove; Because width of keyway is less, centering length is too short, causes the centering precision low; The symmetry requirement be can't satisfy, thereby machining accuracy and part quality influenced.
Summary of the invention
The applicant is to above-mentioned existing large-sized motor shaft extension symmetry keyway processing difficulties; The not high shortcoming of precision; A kind of motor shaft extension rational in infrastructure symmetry keyway processing technology and anchor clamps are provided, thus convenient, correct assurance the symmetry requirement of keyway, and improved working (machining) efficiency.
The technical scheme that the present invention adopted is following:
A kind of motor shaft extension symmetry keyway processing technology may further comprise the steps:
Step 1: process screw in axial end;
Step 2: utilize bolt to be locked at the centering plate on the screw, the last plane of centering plate and lower plane are through flat surface grinding, the depth of parallelism≤0.03mm on two planes up and down;
Step 3: by conventional clamping method with the axle clamping on common boring and milling machine;
Step 4: on boring bar, adorn dial gauge, on plane on the centering plate, play table, utilize the angle between bolt adjustment centering plate and the axle, making beats answers≤0.03mm, clamping screw then;
Step 5: by conventional presetting cutter method, find out the shaft centre line position, mill out a side switch groove;
Step 6: with axle together with the centering plate around shaft centre line Rotate 180 °, through the fine setting rotating shaft, on the lower plane of postrotational centering plate, play table with dial gauge, make to beat≤0.03mm;
Step 7: five same procedure mill out the symmetrical keyway of opposite side set by step.
The anchor clamps of motor shaft extension symmetry keyway being processed according to above-mentioned processing technology; Comprise the V shape iron of pad in the axle bottom; Also comprise the centering plate, the last plane of said centering plate and the depth of parallelism≤0.03mm between the lower plane are fixed on through securing member on the screw of axial end.
Beneficial effect of the present invention is following:
The present invention is under the prerequisite that does not change product structure; Through the centering plate is fixed on the axial end, with the dial gauge method that table is played on the plane on the centering plate, the angle between the indirect detection motor shaft two symmetrical keyways; Thereby centering precision and processing work efficiency have been improved; Easy to operate, precision is high, highly versatile.
Description of drawings
Fig. 1 adds the clamping sketch map in man-hour for a side switch groove of the present invention.
Fig. 2 adds the clamping sketch map in man-hour for opposite side keyway of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing, the specific embodiment of the present invention is described.
Referring to Fig. 1, Fig. 2, concrete processing step of the present invention is following:
Step 1: after axle 1 Vehicle Processing is accomplished, on boring and milling machine, process earlier axial end screw 2;
Step 2: utilize bolt 3 to be locked at centering plate 4 on the axial end screw 2 of shaft end, flat surface grinding is passed through with lower plane 8 in the last plane 5 of centering plate 4, guarantees the depth of parallelism≤0.03mm on two planes up and down;
Step 3: by conventional clamping method with axle 1 clamping on common boring and milling machine, promptly at axle 1 two ends downside pad V shape iron 9, upside compresses with pressing plate, during clamping, approximate horizontal is answered on the last plane 5 of centering plate 4;
Step 4: dress dial gauge 6 on boring bar 7, on plane 5 on the centering plate 4, play table, beat and answer≤0.03mm; Overproof if beat, then utilize the gap between bolt 3 and the screw 2, the angle between adjustment centering plate 4 and the axle 1; Making beats reaches requirement, and clamping screw 3 then;
Step 5: by conventional presetting cutter method, find out axle 1 position of center line, mill out a side switch groove 10;
Step 6: with axle 1 together with centering plate 4 around shaft centre line Rotate 180 °, on the lower plane 8 of postrotational centering plate 4, play table with dial gauge 6, and the method through the fine setting rotating shaft, make to beat≤0.03mm;
Step 7: five same procedure mill out the symmetrical keyway 11 of opposite side set by step.
