The utility model is described in further detail below in conjunction with attached drawing.
This specific embodiment is only the explanation to the utility model, is not limitations of the present invention, ability
Field technique personnel can according to need the modification that not creative contribution is made to the present embodiment after reading this specification, but
As long as all by the protection of Patent Law in the scope of the claims of the utility model.
As shown in Fig. 2, a kind of servo piston repairs roundness measuring equipment, including workbench 1,2 and of the pedestal being fixed on workbench 1
Driving mechanism 3, wherein pedestal 2 is for placing servo piston, and driving mechanism 3 is for driving servo piston to rotate.
As shown in figure 3, pedestal 2 be it is cylindric, the axis of pedestal 2 along the vertical direction, is offered on the top surface of pedestal 2 and is used for
Place matching hole 21, the observation slot 22 for observation of cylindrical end 10.The aperture of matching hole 21 and the outer diameter of cylindrical end 10 match,
Abutting state is able to maintain when the two grafting.The aperture of matching hole 21 is provided with chamfering 211, and cylindrical end 10 is being packed into matching hole 21
During, chamfering 211 can play guiding role, facilitate the installation of servo piston.
The quantity for observing slot 22 is two, and two observation slots 22 are located at the circumferential two sides of matching hole 21.Observe slot 22
Matching hole 21 and 2 outer wall of pedestal are penetrated through, the depth for observing slot 22 is identical as the depth of matching hole 21.It is packed by cylindrical end 10
After matching hole 21, worker can by observe slot 22 intuitively observe whether cylindrical end 10 is installed in place, do not arrive installation site then after
Continuous to push servo piston until being installed in place, after cavetto degree process, the circularity that can improve servo piston to a certain extent reaches
Mark rate.
As shown in Figure 4 and Figure 5, driving mechanism 3 is driven including rack 31, the motor 32 being fixed in rack 31, by motor 32
The dynamic drive block 4 of turn.The output end of motor 32 is coaxially fixed with transmission shaft 33, transmission shaft 33 be located at the surface of pedestal 2 and
Coaxial with pedestal 2, transmission shaft 33 is rotatably dispose in rack 31.The bottom end of transmission shaft 33 offers sliding eye along its axis direction
331, the pass of sliding eye 331 is regular hexagon.The bottom end of transmission shaft 33 has been bolted gland 34, the center of gland 34
Connecting hole 341 is offered, the aperture of connecting hole 341 is less than sliding eye 331.
Multiple driver slots 41 are offered on the bottom surface of drive block 4, arrangement mode, shape and the convex ribs 11 of driver slot 41 are one by one
Corresponding, whole convex ribs 11 can enter in corresponding driver slot 41, produce relative rotation to limit drive block 4 with servo piston.
