The internal screw thread of the external screw thread cooperation of the lateral surface of fixed column 13, by rotary measuring head base 14, adjustable measuring head base 14 and measuring rod
In the distance of vertical direction, the fine tuning of measuring mechanism 2 is realized.When such as rotating clockwise measuring head base 14, can reduce measuring head base 14 with
Measuring rod is in the distance of vertical direction；And counterclockwise rotary measuring head base 14 when, it is possible to increase measuring head base 14 and measuring rod are in vertical side
To distance.The lower end surface area of the measurement seat is greater than the cross-sectional area of measuring rod, convenient for measuring head base 14 in measurement motor
Its lower end surface is butted on machine shaft top when axis stretches size.
In the present embodiment, the guiding mechanism includes overall cylindrical guide cylinder 15, and the operating mechanism includes inserting
It is connected to the pull rod 16 of guide cylinder 15, the quill 7 is socketed on guide cylinder 15.16 outer peripheral surface of pull rod forms two outside water
The flat interconnecting piece 17 extended, as shown in Figure 8.The interconnecting piece 17 passes through the vertical slot of guide cylinder 15, for quill 7
Upward pulling force is provided.The quill 7 contains vertical slot, as shown in figure 3, when pulling up pull rod 16, interconnecting piece 17 to
Upper movement provides movable sleeve upward pulling force when interconnecting piece 17 is butted on the top of the vertical slot of quill 7.Measurement electricity
When arbor stretches size, pull rod 16 is pressed down on, during interconnecting piece 17 moves downward, and interconnecting piece 17 moves downward, measurement
Mechanism 2 is driven by self gravity to be moved down, until the pressure section 9 of motor front end cover block 4 is butted on the upper end of motor front end cover
Face.
When to avoid pressing down on pull rod 16, interconnecting piece 17 provides quill 7 downward driving force, leads to measuring machine
Structure 2, which hits motor, influences accuracy in detection, damage motor and motor-shaft extending size detecting device, the quill 7 it is vertical
The length of slot is preferably longer than or equal to pull rod 16 in the length of vertical direction motion profile.
When to avoid pressing pull rod 16, pull rod 16 generates greater impact power to pedestal 1 and damages motor-shaft extending size detection
Device, the operating mechanism further include elastic component 18.Referring to Fig. 1, the elastic component 18 is spring, when pull rod 16 moves downwardly to
When the back segment of its motion profile, the both ends of elastic component 18 are butted on pull rod 16, on pedestal 1 respectively.It should be appreciated that the elastic component is also
It can be other elastomers of resilient after elastic rubbery body or other removing external force.
Now returning to Fig. 1, Fig. 2, in the present embodiment, the motor-shaft extending size detecting device further includes electric machine spacing mechanism,
The electric machine spacing mechanism is connected with pedestal 1, for limiting the horizontal position of motor.The position-limit mechanism include limited block 19,
First adjusts screw (being not drawn into figure).The limited block 19 be used to be butted on when measuring motor-shaft extending size the side of motor into
And limit the horizontal position of motor.
Specifically, as shown in Figure 9, Figure 10, the limited block 19 includes " V " shape opening portion 20, by 20 two sides of opening portion
Edge extends back and the adjustment portion 21 that is formed, and adjustment portion 21 is containing horizontal strip slot.Described first adjusts the screw rod of screw
It is connected across slot with pedestal 1.When measuring motor-shaft extending size, the shell of motor is butted on the interior of the twenty percent an angle of 90 degrees of opening portion 20
Side, to limit the horizontal position of motor.The radial dimension of its motor housing of the motor of different model is had any different, thus is needed
Adjusted according to the radial dimension of motor housing limited block 19 extension elongation make the shaft of motor be located at gauge head component 5 just under
Side.
When the radial dimension of motor housing is less than normal, unclamps first and adjust screw, to the direction water of 3 side of dial gauge
Flat-pushing dynamic limited block, 1 visual angle of corresponding diagram are Level Promoting limited block to the left, with increase limited block 19 extension elongation until
It is located at the underface of gauge head component 5 with the machine shaft that limited block 19 offsets, then tightens the first adjusting screw, that is, completes limit
The adjusting of block 19；When the radial dimension of motor housing is bigger than normal, unclamps first and adjust screw, to the side of the opposite side of dial gauge 3
To Level Promoting limited block, 1 visual angle of corresponding diagram is Level Promoting limited block to the right, to reduce the extension elongation of limited block 19
Until being located at the underface of gauge head component 5 with the machine shaft that limited block 19 offsets, the first adjusting screw is then tightened, that is, is completed
The adjusting of limited block 19.
Now return to Fig. 1, Fig. 2, in the present embodiment, the pedestal 1 includes bottom plate 22, height adjustment column 23, fixing seat 24.Institute
Height adjustment column 23 is stated to be fixed on vertically on bottom plate 22, the fixing seat 24 is socketed in height adjustment column, fixing seat 24 contain with
Second adjusts the screw hole of screw (being not drawn into figure) cooperation, and the second adjusting screw is butted on height adjustment column 23 in vertical direction difference
Position when changeable fixing seat 24 height.The guide cylinder 15 is connected with fixing seat 24；The lower end of the quill 7 can
It is butted in fixing seat 24, the limited block 19 is connected with fixing seat 24.24 height of fixing seat is adjustable, makes the motor
Axis, which stretches size detecting device, can detecte the motor of different height.
When motor is higher, unclamps second and adjust screw, fixing seat 24 is pulled up, until motor front end cover block 4 is butted on
The upper surface of motor front end cover then tightens the second adjusting screw, that is, completes the adjusting of fixing seat 24.When motor is partially short, pine
The second adjusting screw is opened, fixing seat 24 is pushed and is then tightened until motor front end cover block 4 is butted on the upper surface of motor front end cover
Second adjusts screw, that is, completes the adjusting of fixing seat 24.
In the present embodiment, the fixing seat 24 is also containing the screw hole for adjusting screw (being not drawn into figure) cooperation with third, third
The opposite limit of motor front end cover block 4 can be changed in the lateral surface that adjusting screw is butted on guide cylinder 15 when horizontal direction different position
Position block 19 is in the relative position in horizontal direction.After i.e. third adjusts screw release, rotary steering cylinder 15, due to the company of pull rod 16
Socket part 17 thus when rotary steering cylinder 15, is drawn also cross the vertical slot of vertical slot, quill 7 on guide cylinder 15
Bar 16 and quill 7 can rotate simultaneously, thus can change 4 relative limit block 19 of motor front end cover block in horizontal direction
Relative position, which can reduce the machining accuracy of related components, to reduce motor-shaft extending size detecting device
Manufacturing cost.
