Problems solved by technology

Once the magnetic head 3 of the displacement sensor is disengaged from the bolt 2, the control of the roll gap will be abnormal, the rolling force will be too large, the continuous pipe mill will jam, and even the safety ring of the transmission shaft will break, which will affect the normal production

Embodiment Construction

[0017] as attached Figure 5 Shown: a connection method of a displacement sensor, which is to install a connecting claw 4 between the magnetic head 3 on the extension rod 5 of the displacement sensor and the bolt 2 on the bolt mounting block 1 connected to the servo cylinder, and connect the claw The opening slot 4-3 on the connecting plate 4-1 of 4 is stuck on the screw rod of the bolt 2, and is fixed on the bolt installation block 1 through the bolt 2, and the two claw hooks on the connecting plate 4-1 of the connecting claw 4 are connected. 4-2 Hook the bottom of the head 3. After the connecting claw 4 is installed, it should be ensured that there is a gap of 0.3 mm between the two symmetrical hooks 4 - 2 of the connecting claw 4 and the bottom of the magnetic head 3 .

[0018] as attached figure 2 , 3 , Shown in 4: a kind of displacement sensor magnetic head connects claw, and it comprises a connecting plate 4-1, is provided with an opening groove 4-3 on connecting pla...

Abstract

The invention relates to a connection method of magnetic heads of a displacement transducer expansion rod of a mandrel pipe mill by using a hydraulic gap control (HGC) system to produce seamless steel tubes and a connecting device. The connecting method comprises the following steps: a connecting jackcatch is arranged between the magnetic head of the displacement transducer expansion rod and a bolt on a bolt installation block connected with a servo cylinder; an opening slot on a connecting plate of the connecting jackcatch is stuck in the screw of the bolt and is fixed on the bolt installation block by the bolt; two grabbers on the connecting plate of the connecting jackcatch grab the bottom part of the magnetic head; and a gap of 0.2-0.3mm is left between the two symmetric grabbers and the bottom part of the magnetic head when the connecting jackcatch is mounted well. In the invention, the connecting jackcatch comprises a connecting plate provided with an opening slot, and two symmetric grabbers are arranged at two ends of the connecting plate.

Description

technical field [0001] The invention relates to a connection method and device of a displacement sensor, which is suitable for the field of hydraulic servo control equipment using (SONY Digital Gauging Probe) Sony displacement sensors DG...BP, DG...BN, DG...BS, DG...BL, especially a method using HGC (Hydraulic Roll Gap Control System) The connection method and connection device of the magnetic head of the displacement sensor of the continuous rolling mill for producing seamless steel pipes. Background technique [0002] At present, the limit-stop mandrel rolling mill for producing seamless steel pipes adopts HGC (Hydraulic Roll Gap Control System). Bolt 2 is connected by magnetic force, and its connection method is as follows figure 1 shown. When working, sometimes the magnetic force of the magnet will be reduced due to the vibration of rolling the steel pipe, causing the magnetic head 3 on the displacement sensor to disengage from the bolt 2; The telescopic resistance of...
