Description
Technical Field
The utility model relates to a measuring tool, especially a measuring tool of flat head and flat head cover belong to the measurement field.
Background
The roll changing operation of the hot continuous rolling finishing mill for the strip steel is divided into two parts of pulling and installing, the positions of an upper connecting shaft head and a lower connecting shaft head are required to be clamped and loosened, and the flat heads of the rolls are separated and propped in place. In the operation process, the working roll can not be drawn out and can not be installed in place, so that the roll changing time of a single frame is prolonged by at least 10 minutes. The reason is as follows: the flat head and the flat head sleeve are in or exceed the extreme limit, no detection means is provided for the flat head and the flat head sleeve all the time, whether the size meets the requirement cannot be known, and in addition, objective factors such as the shape, the working position and the like also bring difficulty to measurement. Therefore, it is necessary to design a suitable set of gauge blocks to measure flatheads and flathead sleeves.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem, the measurement of the flat head and the flat head sleeve is realized. The utility model provides a measuring tool of flat head and flat head cover, the technical scheme of the utility model specifically as follows:
the utility model provides a measuring tool of flat head and flat head cover which characterized in that: including the frame, the frame includes upper end arc, lower extreme arc and upper end arc and the connecting portion between the lower extreme arc both ends, and connecting portion are arc or linear type.
Further, when the connecting portion is in the shape of a circular arc, the following parameters are provided: outer diameter of arc
Inner diameter of arc
Distance between the connecting parts
Further, when the connecting part is linear, the following parameters are provided: outer diameter
Distance between the connecting parts
Further, when the connecting part is in the shape of an arc, the thickness of the measuring tool is 32 mm; when the connecting part is linear, the thickness of the measuring tool is 80mm, and the width of the measuring tool is 32 mm; 45 steel is used.
Further, the flathead walk-down deviation has the following parameters: inner diameter of arc
Distance between the connecting parts
Further, the cuff upturn deviation, with the following parameters: inner diameter of arc
Distance between the connecting parts
Compared with the prior art, the beneficial effects of the utility model are as follows:
(1) whether the tolerance of the flat head and the flat head sleeve is qualified or not has a relatively intuitive detection basis, the design of the measuring tool is scientific and applicable, and the detection method is simple and easy to operate. The problem of flat head and flat head cover do not have the detection means, whether the size meets the requirements can't follow and learn, influence the operation is solved.
(2) And a large amount of data collected in the design process provides reference basis for the maintenance of the universal spindle, and the maintenance work of a finish rolling area is perfected.
(3) The operation rate is effectively improved, and the downtime is reduced.
