Detailed Description
The technical solution in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, rather than all embodiments, and all other embodiments obtained by a person of ordinary skill in the art without creative work belong to the protection scope of the present invention based on the embodiments of the present invention.
In the description of the present invention, it should be understood that the terms "front", "back", "left", "right", "up", "down", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of the description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention.
As shown in figure 1, a central deviation measuring apparatu is used in roller assembly, including locating rule 1 and fix at the left dipperstick 3 of locating rule 1 through mount 2, locating rule 1 and dipperstick 3 set up relatively and the axis between them is on same straight line. Two positioning claws 4 are symmetrically arranged on the left side of the positioning ruler 1, and a driving mechanism for driving the two positioning claws 4 to synchronously approach or keep away from is arranged in the positioning ruler 1.
The driving mechanism is shown in fig. 2 and comprises a bidirectional threaded rod 5, a motor 6 for driving the bidirectional threaded rod 5 to rotate and two sliding blocks 7 symmetrically arranged on the bidirectional threaded rod 5. The bidirectional threaded rod 5 is fixed in the positioning ruler 1 through a bearing 8, and one end of the bidirectional threaded rod 5 is fixedly connected with an output shaft of the motor 6. The side wall of the positioning ruler 1 is provided with a sliding groove 9, the two positioning claws 4 respectively penetrate through the sliding groove 9 to be fixedly connected with corresponding sliding blocks 7, and the sliding blocks 7 are respectively in threaded connection with the bidirectional threaded rods 5. When the motor 6 is operated, the bidirectional threaded rod 5 rotates along with the bidirectional threaded rod, and the sliding block 7 slides under the transmission of the bidirectional threaded rod 5, so that the distance between the two positioning claws 4 is adjusted, and the positioning claws 4 can clamp and position the roller 10 from two sides. Because two positioning claws 4 symmetry sets up and synchronous reverse motion all the time, when positioning claw 4 hugs closely roller 10 and presss from both sides it tightly, the axis of location chi 1 and dipperstick 3 can coincide with the axis of roller 10 to the realization is to the location of dipperstick 3.
The sliding sleeve is equipped with two vernier scales 11 on the dipperstick 3, and threaded connection has the locking bolt 12 that is used for restricting its slip on the vernier scale 11. The left sides of the two vernier scales 11 are both fixed with a measuring claw 13, scales are arranged on the measuring scale 3 and the vernier scales 11, and the scales on the measuring scale 3 are symmetrically arranged by taking the central axis of the scale as a starting point. After the center axis of the measuring scale 3 is aligned with the center axis of the roller 10, the two vernier scales 11 are moved so that the measuring claws 13 are respectively brought into close contact with the roller shaft 14 from both sides. And then the vernier scale 11 is locked and fixed through the locking bolt 12 to obtain the corresponding measured values of the two measuring claws 13, and the two measured values are subtracted and then divided by two to obtain the central deviation value (coaxiality tolerance value) of the roller shaft 14 and the roller 10.
Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention.
