Description

TECHNICAL FIELD

[0001] The utility model relates to the field of rolling tool design, specifically refers to a roll center calibration tool. BACKGROUND

[0002] Rolling needs to replace the roll regularly, and the roll can continue to be rolled after grinding off the fatigue layer and reaching the required accuracy. The roll is ground on a special roll grinder, and a bracket is used to hold the roll during grinding. The driving disc drives rotation, and the grinding head reciprocates to grind. The roll rotation center needs to coincide with the center of the driving disc as much as possible to achieve the required grinding accuracy.

[0003] The roll center can be generally aligned by the measuring system of the grinder. When the system is not normal, the related mechanical parts are worn out, or the related spare parts are replaced, etc., it needs to be recalibrated. Re-calibration requires the installation of a specially designed calibration roll and many special tools, which is quite cumbersome and requires high professional skills. UTILITY MODEL CONTENT

[0004] The utility model mainly solves the problem of multiple and cumbersome roll center calibration tools.

[0005] To solve the above problems, the technical scheme adopted by the utility model is as follows: the utility model is a roll center calibration tool, which comprises a mounting plate, the mounting plate is provided with mounting holes, the mounting holes are symmetrically provided with multiple groups, the mounting plate is provided with a positioning device, the positioning device is provided with a measuring device, the positioning device comprises a sliding sleeve and a sliding rod, the sliding sleeve is arranged on the mounting plate, and the sliding rod is clamped and slides on the sliding sleeve.

[0006] Further, the mounting plate is provided with a through opening.

[0007] Further, the mounting plate and the sliding sleeve are provided with a rib plate.

[0008] Further, the sliding sleeve is provided with multiple groups of adjusting screw holes.

[0009] Further, the measuring device comprises a connecting seat and a fixing bolt, the connecting seat is arranged on the sliding rod, the connecting seat is provided with a measuring opening, the fixing bolt is provided with two groups, and the fixing bolt is threadedly connected to the connecting seat and located on both sides of the measuring opening.

[0010] Further, the connecting seat is made of steel.

[0011] The utility model adopts the above structure and achieves the following beneficial effects:

[0012] The structure is very simple, the cost is low, and an ordinary operator can adjust and calibrate the roll center by using normal rolls and some common tools, which is simple, convenient and high in precision. BRIEF DESCRIPTION OF DRAWINGS

[0017] As shown in the description accompanying drawings Figs. 1-2 The utility model provides a roll center calibration tool, including mounting plate 1, being equipped with mounting hole 2 on mounting plate 1, mounting hole 2 is equipped with multiple groups symmetrically, being equipped with aligner 3 on mounting plate 1, being equipped with measurer 4 on aligner 3, aligner 3 includes sliding sleeve 5 and sliding rod 6, sliding sleeve 5 is located on mounting plate 1, and sliding rod 6 is clamped and slides on sliding sleeve 5. Through opening 7 is equipped on mounting plate 1. Rib plate 8 is equipped between mounting plate 1 and sliding sleeve 5. Multiple groups adjusting screw hole 9 are equipped on sliding sleeve 5, and using fixing bolt is inserted into screw hole 9 for fixing the position between sliding sleeve 5 and sliding rod 6.

[0018] As shown in the description accompanying drawings Figs. 1-3 Measurer 4 includes connecting seat 10 and fixing bolt 11, connecting seat 10 is located on sliding rod 6, and measuring port 12 is penetrated on connecting seat 10, and fixing bolt 11 is equipped with two groups, and fixing bolt 11 is screw-connected on connecting seat 10 and is located on both sides of measuring port 12, and connecting seat 10 uses steel material, and can attract dial magnetic base plate.

[0019] Specific use: the depth vernier caliper is installed on the connecting seat 10, the bottom probe is out of the measuring port 12, the extension length of the sliding rod 6 is adjusted according to the position of the roller, the adjusting bolt is turned into the adjusting screw hole 9, the sliding sleeve 5 and the sliding rod 6 are fixed, the depth vernier caliper is used to measure the distance from the roller to the connecting seat 10. Rotate the grinder rotating disc in turn, and measure the data of four points of up, down, left and right. According to the measured data analysis, adjust the grinder supporting tile. Repeat the above steps, so that the center of the roller and the machine tool are basically coincided. Replace the depth vernier caliper with a dial gauge, the magnetic base is attracted to the connecting seat 10, the rotating disc is rotated, and the dial gauge reading is found to be correct, which can be accurate to 0.01mm.
