Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1 to 3, in an embodiment of the present invention, a thickness gauge transmission roller 20 includes a roller 20, the roller 20 rolls on a roller 10, and a center of gravity of the roller 20 and a center of gravity of the roller 10 lying horizontally are on the same vertical plane, so that a center of gravity shift of the roller 20 during a movement process can be avoided, and an increase in wear between the roller 20 and the roller 10 can be avoided.

The inside through-hole with the axle center of having seted up of gyro wheel 20, the through-hole both ends opening part is equipped with the internal thread, and bearing 21 passes through interference fit and installs the inside at gyro wheel 20. The circumferential surface of the outer ring of the bearing 21 is in contact with the inner wall surface of the through hole to form a smooth contact surface, and the contact surface and the internal thread are mutually avoided. The two ends of the roller 20 are screwed with positioning sleeves 23, a gasket 22 is arranged between the bearing 21 and the positioning sleeve 23, and the screwed end of the positioning sleeve 23 tightly presses the gasket 22 against the end surface of the outer ring of the bearing 21. The washer 22 can reduce the wear between the bearing 21 and the positioning sleeve 23, and can reduce the production cost.

The bearing 21 is firmly installed inside the roller 20 under the abutting action of the positioning sleeves 23 at the two ends. The same positioning sleeves 23 are adopted at both ends of the roller 20, and the structure can adjust the position of the bearing 21 in the axial direction in the roller 20 so as to ensure that the center of gravity of the whole roller 20 is always on the same vertical plane with the center of gravity of the roller 10, and reduce the abrasion between the roller 20 and the roller 10.

The end of the positioning sleeve 23 outside the roller 20 is provided with grooves 231 with the groove length direction along the axial direction of the roller 20, and the grooves 231 are evenly distributed along the circumferential direction of the positioning sleeve 23. The groove 231 can increase the contact friction force of the hand in the screwing process of the positioning sleeve 23, so that the screwing is more stable and sufficient.

To prevent the retainer 23 from loosening during movement of the roller 20, a clamping assembly is provided that cooperates with the recess 231. The clamping assembly comprises a baffle 24 and a guide plate which are arranged on the side surface of the roller 20, a guide groove is radially formed in the guide plate along the roller 20, and a sliding clamping plate 26 capable of sliding along the guide groove is arranged in the guide groove. A spring 25 is compressed between the catch plate 26 and the baffle 24, and the spring 25 abuts against the catch plate 26 to clamp the catch plate in the groove 231. The catch plate 26 is provided with a catch plate for sliding the catch plate 26 along the guide slot to disengage the recess 231. When the positioning sleeve 23 needs to be screwed into the roller 20, the catch plate 26 is separated from the groove 231 by lifting the pull tab, and the positioning sleeve 23 is screwed into the roller 20. When the positioning sleeve 23 is screwed in place, the shifting piece is loosened, and the clamping plate 26 is clamped back into the groove 231 again under the action of the spring 25, so that the positioning sleeve 23 is prevented from being loosened.
