Description

The instrument that shakes that a kind of centering milling train verticality is used

Technical field

The utility model relates to a kind of centering instrument, relates in particular to the instrument that shakes that a kind of centering milling train verticality is used.

Background technology

The centering of milling train base plate, memorial archway is a critical process in the milling train installation process, especially when carrying out base plate, memorial archway and the adjustment of roll line verticality, the method of being taked in the past, mainly be to utilize transit to emit a machine row reference center line perpendicular with roll line, utilize suspension piano wire and line to weigh down alignment machine row reference center line again, utilize micrometer inside caliper to look for the depth of parallelism of milling train base plate, memorial archway and this piano wire again, thereby guarantee the verticality of milling train base plate, memorial archway and roll line.There is following deficiency in this aligning method: 1. be not direct measuring vertical degree may cause to survey data not accurate enough.2. all there is error in each step, causes cumulative errors excessive.3. cause the increase of human and material resources, time.4. in rolling a cold rolling mill base plate, memorial archway and the adjustment of roll line verticality, can't guarantee precision.

Summary of the invention

The purpose of this utility model is to overcome the deficiency of prior art, and a kind of centering milling train base plate, memorial archway and roll line verticality are provided, and guarantees the accuracy of measurement data, and then guarantees the instrument that shakes that a kind of centering milling train verticality of the installation accuracy of milling train is used.

The instrument that shakes that a kind of centering milling train verticality of the present utility model is used, it comprises axle, every end at the two ends of described axle clamps respectively in the hole that is arranged on a sliding bearing, the sidewall of each described sliding bearing and a base are fixedly linked, each described base and a locating support are fixedly linked, each described locating support is provided with the protruding arm that has pilot hole on it, two bolts pass pilot hole and two ends holding out against described axle, its end on the protruding arm separately and are provided with, one end of a rocking arm and described axis clamping setting and its other end and anchor clamps connector clamp and are provided with, and anchor clamps and anchor clamps connector are fixedly linked.

This structure is compared with present existing technology and is had following advantage:

1. adopt the utility model structure can directly measure the verticality of milling train base plate, memorial archway and roll line.

2. reduce the derivation step of datum line, dwindled the influence that cumulative errors causes, guaranteed the accuracy of measuring.

3. saved and installed used human and material resources and the time of centering.

4. be applicable to various types of milling trains.

Embodiment

Below in conjunction with the drawings and specific embodiments the utility model is done to describe in detail.

The instrument that shakes 12 that a kind of centering milling train verticality of the present utility model is used shown in Fig. 1-14, it comprises axle 3, every end at the two ends of described axle 3 clamps respectively in the hole that is arranged on a sliding bearing 2, each described sliding bearing 2 and a base 1 are fixedly linked, each described base 1 and a locating support 4 are fixedly linked, each described locating support 4 is provided with the protruding arm that has pilot hole on it, two bolts 5 pass pilot hole and two ends holding out against described axle 3, its end on the protruding arm separately and are provided with, one end of a rocking arm 6 clamps setting with described axle 3 and its other end is connected setting with 7 clampings of clamping connector, and anchor clamps 8 can be fixedly linked by welding and anchor clamps connector 7.In use micrometer inside caliper 10 is positioned over anchor clamps 8 internal fixation, and dial gauge 9 is fixed in the rolling-mill housing base by the magnetic force gauge stand, detects shaft run-out and axial displacement when shakeing.

Originally the using method of instrument of shakeing is as follows:

1. the squareness measurement between milling train base plate and roll line is (as Figure 15,16, shown in 17): second base of the instrument 12 that will shake is fixed on the rolling-mill housing base plate 13, dial gauge 9 is fixed on the rolling-mill housing base plate 13 by the magnetic force gauge stand, the test rod measurement axis surface of dial gauge 9, rotating shakes instrument rocking arm 6 and adjust sliding bearing 2 remains unchanged two dial gauges, 9 readings substantially, axle head is placed a dial gauge 9 again, the test rod measurement axis end face of dial gauge 9, the shake axial displacement of process axis of detection, one milscale 10 is installed in anchor clamps 8, cooperate the earphone listening, shake two precalculated positions of rocking arm 6 to the piano wire of instrument 12 of rotation, read the reading of milscale 10 and 11 distances of rolling center piano wire, and further calculate verticality between milling train base plate and roll line, be respectively A as two precalculated position micrometer inside caliper 10 measurement results of piano wire, B, distance is L between two precalculated positions of piano wire, then just can draw verticality according to formula (A-B)/L.

2. the squareness measurement between memorial archway benchmark window and roll line (shown in Figure 18,19,20): utilize lifting jack 16 and support member 17 that steel leveling ruler 14 is fixed on the upright plane of rolling-mill housing two memorial archways 15 benchmark windows, make leveling ruler 14 maintenance levels with the square level measurement, first base of the instrument of shakeing 12 is fixed on the leveling ruler 14, then 1 verticality of measuring between rolling-mill housing memorial archway benchmark window and roll line according to the method described above.
