Magnetic core tube pressure test oil circuit docking device and turntable pressure test machine

Abstract

The invention discloses a pressure resisting detection oil route docking device for a magnetic core pipe and a rotary table type pressure resisting tester, and belongs to the technical field of electromagnet manufacturing equipment. The docking device comprises oil route blocks, each oil route block is provided with a baffle, and mobile oil pressure supplying devices are arranged near the move path of the oil route blocks; the mobile oil pressure supplying devices comprise guide rails which are arranged on guide rail front seats and guide rail back seats, holding oil cylinder connecting plates are slidably arranged on the guide rails, springs are arranged between holding oil cylinders and the guide rail front seats, cylinder rods of the holding oil cylinders are connected with striping blocks matched with the baffles, and the oil cylinder connecting plates are fixedly provided with pressure supplying oil nozzles which are connected to a hydraulic station. The pressure resisting tester is provided with the pressure resisting oil route docking devices in a matched mode. The detection efficiency of the rotary table type pressure resisting tester formed by adopting the docking devices is high.

Description

technical field [0001] The invention relates to a magnetic core tube pressure-resistant oil circuit docking device and a turntable type pressure-resistant testing machine, belonging to the technical field of electromagnet manufacturing equipment. Background technique [0002] In the process of electromagnet manufacturing and processing, the core tube of each electromagnet must be subjected to a pressure test before leaving the factory, and the quality inspection of the processed core tube is performed. Generally, the pressure test is performed in a large oil A plurality of magnetic core tubes are installed on the road block. After the installation, the high-pressure oil is passed through to reach the pressure to be detected, the high-pressure oil is stopped, and the pressure is maintained by the one-way valve. The pressure-holding time is at least one minute. After the pressure-holding time is up, check whether the pressure has dropped, and check the magnetic core tube by ha...

Problems solved by technology

In this process, if there is oil leakage or oil leakage in a pipe during the high-pressure holding process and the pressure drops, it is necessary to check all the core tubes on the large oil block and pick out the core tubes that leak or leak oil. , Remove and replace with a new magnetic core tube and re-press to ensure product quality. This detection method results in low efficiency of repeated work. If multiple oil circuit blocks are fixed on one turntable, one magnetic circuit block is fixed on one If the core tube is used, then multiple oil circuit blocks are required, and each oil circuit block must be equipped with a set of solenoid valves and a set of oil pipes. The rotary table type pressure-resistant machine also needs to solve the problem of oil pipe winding caused by the rotation of the turntable.
