A motor assembling axle high detection mechanism
Technical field
The utility model relates to motor mounting technology field, is specifically related to a kind of motor shaft high detection mechanism that uses in the motor automatic assembly line.
Background technology
In the prior art, in the group of motors process of assembling, adopt manual with electric machine casing, end cap, stator, rotor set install to together up and down, need not to detect the axle height of motor; And in the automatic assembly line of motor, owing to need not manually to assemble, just need employing equipment to detect the height of motor shaft, whether put in place with this installation of determining rotor.
Summary of the invention
At above-mentioned technical matters, the utility model provides an a kind of motor assembling high detection mechanism that uses in the motor production line for automatically assembling, and it is the height of detection rotor axle automatically, to determine the rigging position of rotor.
The realization the technical solution of the utility model is as follows:
A motor assembling axle high detection mechanism, comprise support, be set with substrate on the support, substrate is provided with lifter plate, described lifter plate bottom is set with dial gauge, and is arranged on the drive unit that drives the lifter plate rising on the substrate, descends, and drive unit comprises the motor that is fixedly installed on the substrate, and the drive screw that connects with motor output shaft, lifter plate is provided with the slave thread that cooperates with drive screw; At least be set with a guide rail of arranging up and down on the described substrate, be set with the slide block that is slidingly matched with guide rail at lifter plate.
Further, described substrate top is provided with upper stroke switch, and the bottom is provided with lower stroke switch, is set with the shake-up piece that touches upper stroke switch, lower stroke switch on the described lifter plate.Under the lifter plate/on move, touch piece also one to remove/up and touch down/upper stroke switch, quit work by controller control motor like this, lifter plate stops down/on move, play position-limiting action.Described upper stroke switch, lower stroke switch can be adjusted in the position on the lifter plate as required.
Further, described dial gauge is digital display centimeter.
Adopted such scheme, in the motor automatic assembly line, set in advance the position of lower stroke switch as required, when needs detection rotor axle (motor shaft) is high, rotate by motor, drive drive screw, driving screw thread on the drive screw cooperates with the slave thread on the lifter plate and carries out transmission, realize the decline of lifter plate, thereby dial gauge moves down thereupon also, the detection axle of dial gauge contacts with armature spindle and detects, the detection rotor axle highly just often, numeral on the dial gauge is zero, and when error occurring, dial gauge shows numeral; The utility model need not manually-operated, just can detect the height of armature spindle, to determine the installation site of armature spindle.
Description of drawings
Fig. 1 is perspective view of the present utility model;
Fig. 2 is side schematic view of the present utility model;
Among the figure, 1 is support, and 2 is substrate, and 3 is lifter plate, and 4 is digital display centimeter, and 5 is motor, and 6 is drive screw, and 7 is guide rail, and 8 is slide block, and 9 is upper stroke switch, and 10 is lower stroke switch, and 11 for touching piece, and 12 is armature spindle, and 13 for detecting axle.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is further specified.
Referring to Fig. 1,2, a motor assembling axle high detection mechanism, comprise support 1, be set with substrate 2 on the support, substrate 2 is provided with lifter plate 3, and lifter plate 3 bottoms are set with digital display centimeter 4, and the drive unit that is arranged on driving lifter plate rising on the substrate, descends, drive unit comprises the motor 5 that is fixedly installed on the substrate, and the drive screw 6 that connects with motor output shaft, and lifter plate is provided with the slave thread that cooperates with drive screw; Be set with the guide rail 7 that two above-below directions are arranged on the substrate, be set with the slide block 8 that is slidingly matched with guide rail 7 at lifter plate.Offer the gathering sill identical with the guide rail cross sectional shape on the slide block, stroke limit also can lead in the guide rail insertion gathering sill; In addition, substrate 2 tops are provided with upper stroke switch 9, and the bottom is provided with lower stroke switch 10, are set with the shake-up piece 11 that touches upper stroke switch, lower stroke switch on the lifter plate 3.
Principle of work of the present utility model: at needs detection rotor axle 12(motor shaft) when height, rotate by motor 5, drive drive screw 6, the driving screw thread on the drive screw cooperates with the slave thread on the lifter plate and carries out transmission, the decline of realization lifter plate 3, thereby digital display centimeter 4 also moves down thereupon, the detection axle 13 of digital display centimeter contacts with armature spindle and detects, the detection rotor axle highly just often, the numeral on the dial gauge is zero, when error occurring, dial gauge shows numeral.
