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
The present invention relates to a kind of method of attachment and device of displacement transducer, be adapted to adopt (SONY Digital Gauging Probe) displacement transducer DG of Sony ... BP, DG ... BN, DG ... BS, DG ... BL hydraulic servo control appliance field, particularly method of attachment and the jockey of the magnetic head of the tandem rolling tube machine displacement transducer expansion link of a kind of employing HGC (Hydraulic Roll Gap Control System) production seamless steel pipe.
Background technology
At present, the limiting mandrel tandem rolling pipe machine of producing seamless steel pipe has adopted HGC (Hydraulic Roll Gap Control System), the magnetic head 3 that is installed on the displacement transducer expansion link 5 is to link to each other by magnetic force with bolt 2 on the bolt mounting blocks 1 that links to each other with servo-cylinder, and its connected mode as shown in Figure 1.During work, the vibration during sometimes because of rolled steel tube, the magnetic force of magnet can reduce because of vibration, causes that the magnetic head 3 on the displacement transducer is thrown off with bolt 2; In addition, the residing environment of displacement transducer is poor, dirt in the turbid circulating water slowly increases the flexible resistance of the expansion link of displacement transducer, when the magnetic force of 2 on magnetic head 3 and bolt during less than the resistance of motion of displacement transducer expansion link, displacement transducer magnetic head 3 also can with bolt 2 disengagements.Once displacement transducer magnetic head 3 and bolt 2 are thrown off, will cause roll gap control undesired, roll-force is excessive, and tandem rolling tube machine rolls card, even the fracture of power transmission shaft safety collar, and impact is normally produced.
Summary of the invention
The objective of the invention is to overcome the above-mentioned deficiency of prior art and a kind of method and device that guarantees that the magnetic head on the displacement transducer expansion link and bolt reliably are connected is provided.
Technical scheme of the present invention is: a kind of method of attachment of displacement transducer, it be the magnetic head on the displacement transducer expansion link with and the bolt mounting blocks that links to each other of servo-cylinder on bolt between install one and be connected claw, open slot on the connecting plate of connection claw is stuck on the screw rod of bolt, and be bolted on the bolt mounting blocks two bottoms that claw hook hooks magnetic head on the connecting plate of connection claw.After connecting claw and installing, should guarantee to connect the gap that 0.2～0.3mm is arranged between the bottom of two symmetrical claw hooks of claw and magnetic head.
A kind of magnetic head connecting jaw of displacement sensor, it comprises a connecting plate, is provided with an open slot at connecting plate, is provided with the claw hook of two symmetries at the two ends of connecting plate.
Magnetic head connecting jaw of displacement sensor adopts the nonmagnetic substance manufacturing.
The present invention compared with prior art has following features:
The flexible resistance of vibration when 1, having solved because of rolled steel tube or the expansion link of displacement transducer is excessive, causes that displacement transducer upper magnetic head and bolt throw off, cause roll gap control undesired, roll-force is excessive, tandem rolling tube machine rolls the card problem.
2, tandem rolling tube machine rolls card and reduces, and can prolong tandem rolling tube machine roll and plug service life, reduces roll and plug consuming cost.
3, can reduce power transmission shaft safety collar breaks, and can reduce the cumulative damage to main frame and HGC system, thereby save cost of equipment maintenance.
Below in conjunction with the drawings and specific embodiments detailed construction of the present invention is further described.
