Abstract
The utility model provides a center positioner of a three-high mill and belongs to the field of rolling seamless steel pipes. The center positioner comprises measure plates, a measure sleeve and a positioning center pin, wherein the centers of the measure plates are provided with screw holes, three measuring scales being same in length are distributed outwardly from the center, the included angle between two adjacent measuring scales is 120 degrees, a pinhole is respectively arranged at the same position on the end portions of the three measuring scales, and front and rear measure plates are fixed on the front and rear frames of the three-high mill via the pin holes on the end portion of the measuring scales. The positioning center pin penetrates through the screw holes of the front and rear measure plates, and the tubular measure sleeve is sleeved over the positioning center pin. The positions of three rollers are adjusted according to the position sleeve, and the axis direction of the positioning center pin is the central shaft of the three-high mill. The center positioned is simple in structure, convenient for measuring and high in efficiency and accuracy.
Description
Technical field
The utility model belongs to seamless rolling technical field, especially relates to a kind of three-high mill center positioning device.
Background technology
At present, the center main of three-high mill will rely on laser or tape measuring, and high but laser measurement requires environment and machining accuracy etc., the tape measuring precision is lower.The technical problems such as therefore, the measurement difficulty is confirmed to exist in the center of three-high mill, and certainty of measurement is inadequate.
Summary of the invention
Problem to be solved in the utility model provides a kind of three-high mill center positioning device, is particularly useful for three-high mill and determines the center and regulate the roller distance.
For solving the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of three-high mill center positioning device, comprise and measure plate, measuring unit and centre of location axle, the center of described measurement plate is provided with screw, dip stick by outside three equal length that distribute in center, angle between two adjacent dip sticks is 120 degree, and the same position place, end of three dip sticks respectively is provided with a pin-and-hole; The fore-and-aft survey plate is fixed on the front and back frame of three-high mill by the pin-and-hole of dip stick end; Centre of location axle is fixed in the center screw of fore-and-aft survey plate; String has the tubulose measuring unit on the centre of location axle.
The pipe thickness of described measuring unit is determined by producing required roll spacing.
Advantage and the good effect that the utlity model has are: owing to adopt technique scheme, determine that the center of three-high mill is convenient; And the three-high mill center positioning device that the utility model provides has simple in structure, easy to maintenance, and processing cost is low, the production efficiency advantages of higher.

The specific embodiment
As shown in Figure 1 and Figure 2, the utility model provides a kind of three-high mill center positioning device, comprise measurement 1, measuring unit 2 and centre of location axle 3, the center of described measurement plate 1 is provided with screw 11, dip stick 12 by outside three equal length that distribute in center, angle between two adjacent dip sticks 12 is 120 degree, and the same position place, end of three dip sticks 12 respectively is provided with a pin-and-hole 13; Fore-and-aft survey plate 1 is fixed on the front and back frame of three-high mill by the pin-and-hole 13 of dip stick 12 ends; Centre of location axle 3 is fixed in the center screw 11 of fore-and-aft survey plate 1; String has tubulose measuring unit 2 on the centre of location axle 3.
The pipe thickness of described measuring unit 2 is determined by producing required roll spacing.
The course of work of this example: at first, according to the dimensional characteristic of three-high mill frame itself, according to the position of roll, each makes a call to 3 pin-and-holes on the frame of front and back, and dip stick 12 ends that a side is measured on the plate 1 are fixed in the pin-and-hole on the side rolling-mill housing with pin.Then, cover there is the centre of location axle 3 of measuring unit 2 be installed in the center screw 11 of rack-mounted measurement plate 1.The 3rd step was fixed by a pin to the measurement plate 1 of the other end on the opposite side frame, and in the center screw 11 of the measurement plate 1 installed on the frame before and after being individually fixed in of the two ends of guaranteeing centre of location axle 3.The 4th step, adjust three rolls, make roll mutually circumscribed with measuring unit 2.The axis direction of centre of location axle 3 is the central shaft of three-high mill, and the size by measuring unit 2 calculates roll spacing.
More than an embodiment of the present utility model is had been described in detail, but described content only is preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., all should still belong within the patent covering scope of the present utility model.
