Abstract
Description
Technical Field
[0001] The utility model relates to an auxiliary clamping tool for grinding a working roller of a straightening machine, and belongs to the technical field of offline repair auxiliary equipment for straightening machines in the metallurgical industry. Background Art
[0002] During the rolling process, due to uneven temperature and deformation of the rolled piece, cooling after rolling and other factors, the rolled product often has defects such as bending. For example, the steel plate often has sickle bends, waves in the width direction of the steel plate, waves in the longitudinal and transverse directions of the steel plate, waves in the middle and waves on the edges. The straightening machine is used to straighten the rolled steel plate to eliminate the defects of the steel plate itself, so that it meets the specified standards and meets the needs of manufacturers and users.
[0003] When the working roll of the straightening machine has completed its full cycle or cracks or other quality abnormalities appear on the surface of the roll, the working roll needs to be taken offline and welded and ground offline in time. The ground roll is then put back online for operation. In the grinding process after welding, due to the large size of the roll, for example, a roll of Φ285 and a length of 5420mm, it is difficult to adjust its coaxiality after being fixed on the machine using the original chuck and top screw. Utility Model Content
[0004] The utility model aims to provide an auxiliary clamping tool for grinding the working roller of a straightening machine, which can quickly fix and level the working roller of the straightening machine during grinding on the machine tool, improve the grinding efficiency of the working roller, and solve the problems existing in the background technology.
[0005] The technical solution of the utility model is:
[0006] A straightening machine working roller machine tool grinding auxiliary clamping tool comprises a circular chuck and an adjusting bolt. A circular groove is provided on one side of the circular chuck, and a plurality of bolt holes are evenly arranged in the circumferential direction of the circular groove, and an adjusting bolt is provided in each bolt hole; a positioning hole is provided on the other side of the circular chuck which is concentric with and connected to the circular groove.
[0007] The positioning hole on the other side of the circular chuck which is concentric with and communicates with the circular groove is a tapered hole, and the size of the tapered hole matches the top pin of the lathe.
[0008] The size of the circular groove on one side of the circular chuck matches the size of the roller shaft at the passive end of the working roller of the straightening machine.
[0009] There are four bolt holes evenly arranged in the circumferential direction of the circular groove.
[0010] The beneficial effect of the utility model is that the fixing and leveling of the working roller of the straightening machine during the machine tool grinding can be quickly achieved through the circular chuck and the adjusting bolt, which greatly shortens the working efficiency of the machine tool leveling and grinding of the working roller.

[0016] The present invention will be further described below by way of examples with reference to the accompanying drawings.
[0017] Refer to the attached Figure 1-4 A straightening machine working roller grinding auxiliary clamping tool comprises a circular chuck 6 and an adjusting bolt 7. A circular groove 9 is provided on one side of the circular chuck 6. A plurality of bolt holes 1 are evenly arranged in the circumferential direction of the circular groove 9. An adjusting bolt 7 is provided in each bolt hole 1. A positioning hole 8 which is concentric with and connected to the circular groove 9 is provided on the other side of the circular chuck 6.
[0018] In this embodiment, refer to the attached Figure 1-4 The outer diameter of the circular chuck 6 is 195 mm. A groove 9 with a diameter of 150 mm and a depth of 40 mm is provided on one side of the circular chuck 6. Four bolt holes 1 with a hole diameter of 20 mm are evenly arranged in the circumferential direction of the groove 9. A tapered hole 8 with an outer diameter of 40 mm, an inner diameter of 15 mm and a depth of 20 mm is provided on the other side of the circular chuck 6 and is connected to the groove 9.
[0019] The adjusting bolt 7 is M20mm, X60 thread.
[0020] Refer to the attached Figure 4 To use this tool, follow these steps:
[0021] (1) First, insert the groove 9 of the circular chuck 6 into the passive end of the work roll 2, and then use the adjusting bolt 7 to initially fix it;
[0022] (2) Use a crane to lift the working roll 2 onto the lathe 4. The shaft neck without the circular chuck 6 is firmly fixed with the chuck 3 provided by the machine tool. The end of the circular chuck 6 is passed through the tapered hole 8 by the lathe ejector pin 5 to be combined with the positioning hole of the working roll 2 and firmly pushed.
[0023] (3) Place the magnetic dial indicator on the machine tool, align the indicator needle with the upper surface of the working roll 2, rotate the roll 2, and adjust the concentricity of the working roll 2 by tightening or loosening the adjusting bolt 7 until the concentricity reaches the range of ±0.05 mm.
[0024] (4) Grind the working roll 2 using a lathe.
[0025] The straightening machine working roll grinding clamp auxiliary tool can adjust the concentricity of the working roll on the machine tool through four adjusting bolts in conjunction with a dial indicator, which can greatly shorten the adjustment time of the working roll, reduce the labor intensity of workers and improve production efficiency.
