Abstract

A rolling device and a measuring device are disclosed. A rolling assembly in the rolling device is movably mounted on a bracket in a first direction (a) parallel to a working surface, and when a member to be rolled is placed on the working surface, the rolling assembly provides a rolling pressure to the member to be rolled. In a rolling process, the rolling assembly moves in the first direction (a), so as to be capable of ensuring that the rolling pressure applied to the member to be rolled is constant and always perpendicular to the member to be rolled, that is, ensuring that the rolling pressure remains constant, thereby reducing the influence of external factors on the rolling process and improving the accuracy of a measurement result.

First claim

The invention claimed is:

1. A rolling device, comprising:
a base having a working surface for placing a member to be rolled;
a bracket arranged on the base; and
a rolling assembly movably mounted on the bracket in a first direction, the rolling assembly being used for providing a pressure to the member to be rolled on the working surface; wherein the first direction is parallel to the working surface; herein the rolling assembly comprises a connecting element and a rolling member, the connecting element is movably mounted on the bracket in the first direction, the rolling member is rotatably arranged on the connecting element around a rotating shaft, and an axial direction of the rotating shaft is parallel to the working surface; wherein the connecting element comprises a connecting main body as well as a first connecting beam and a second connecting beam respectively arranged on the connecting main body, the first connecting beam and the second connecting beam are respectively located on two opposite sides of the rolling member in the axial direction of the rotating shaft, and the first connecting beam and the second connecting beam are each provided with a through hole for accommodating the rotating shaft;
characterized in that the through hole is configured as a kidney-shaped hole extending in a third direction and the third direction is arranged to intersect the working surface.

2. The rolling device according to claim 1 , wherein the rolling device comprises a guiding member arranged on the bracket, and a matching portion that matches the guiding member is arranged on the connecting element, so that the connecting element is capable of moving in the first direction.

3. The rolling device according to claim 2 , wherein the guiding member is configured as a guide rail extending in the first direction, and the matching portion is configured as a slider that fits the guide rail.

4. The rolling device according to claim 3 , wherein the guide rail comprises a first sub-guide rail and a second sub-guide rail arranged at an interval in a second direction, the slider comprises a first sub-slider and a second sub-slider corresponding to the first sub-guide rail and the second sub-guide rail, respectively, and the connecting element is connected between the first sub-slider and the second sub-slider;
wherein the second direction intersects the first direction, and the second direction is parallel to the working surface.

5. The rolling device according to claim 1 , wherein the rolling device further comprises first position limiting members arranged at opposite ends of the bracket in the first direction, and the first position limiting members are used for limiting the rolling assembly on the bracket in the first direction.

6. The rolling device according to claim 1 , wherein an accommodating groove for placing at least a part of the member to be rolled is arranged on the working surface, and the depth of the accommodating groove is smaller than the thickness of the member to be rolled.

7. The rolling device according to claim 6 , wherein the accommodating groove has a closed end and an open end oppositely arranged in the first direction, and in a direction from the open end to the closed end, the closed end is capable of limiting the position of the member to be rolled in the accommodating groove.

8. The rolling device according to claim 7 , wherein a second position limiting member is arranged on the base, the second position limiting member is arranged corresponding to the open end at an interval, and in a direction from the closed end to the open end, the second position limiting member is capable of limiting the position of the member to be rolled placed in the accommodating groove.

9. The rolling device according to claim 1 , wherein the rolling device further comprises an operating member arranged on the rolling assembly, and the operating member is used for providing a force application position on the rolling assembly.

10. A measuring device, comprising the rolling device according to claim 1 .
