Abstract
The utility model provides a portable magnetic force hydraulic pressure Brinell hardness meter which solves the problems that when an existing hydraulic pressure Brinell hardness meter is used for testing, a work-piece to be tested needs to be clamped between a base and a hardness measuring head, the larger work-piece can not be tested due to the limitation of the largest lifting height of the hardness measuring head, and a test force is small due to the fact that the magnetic force sucker Brinell hardness meter depends on a hand wheel and a spiral micrometer mechanism to apply force. The portable magnetic force hydraulic pressure Brinell hardness meter is characterized in that the two sides or one side of a hydraulic pressure integrated block is connected with a magnetic force sucker through a connecting plate. The portable magnetic force hydraulic pressure Brinell hardness meter has the advantages that as the magnetic force sucker structure is adopted, the hardness meter depends on the magnetic force sucker to be attracted to the surface of the tested work-piece, samples do not need to be supported, the work-piece does not need to be clamped, and test can be finished only by making contact with one side of the tested work-piece. Accordingly, Brinell hardness of steel type work-pieces of any large size can be tested. As a hydraulic pressure stress application system is adopted for stress application, the test force of 750kg-3000kg can be provided, and the requirement for testing the Brinell hardness of most large industrial parts can be met.

The application number that the applicant proposes is that 200820231921.9 patented claim discloses a kind of portable hardometer, this scleroscopic principal feature is in the supporting base both sides magnetic suction disc to be set, rely on magnetic force that sclerometer is adsorbed on the measured workpiece surface, do not need sample is carried out clamping, contact workpiece one side can realize the hardness test to large-scale workpiece, but, the problem that this sclerometer exists is, it is to rely on a handwheel and spiral micrometer mechanism to apply test power, so test power is less, maximum can only reach 187.5kg, can only use the bead pressure head of 2.5mm to measure, this small test power, the test condition that bead is measured can't satisfy the requirement of many large-scale workpiece Brinell hardness tests.
Summary of the invention
Technical problem to be solved in the utility model is, overcomes the deficiencies in the prior art and defective, and a kind of bigger test power that has is provided, and can be used for the portable magnetic hydraulic pressure Brinell tester that large-scale iron and steel class workpiece Brinell hardness detects.
The technical solution adopted in the utility model comprises magnetic suction disc, ball pressure head, hydraulic manifold block, is used for showing tensimeter, afterburning handle and the compression relief cock of test power value that described hydraulic manifold block is connected by web joint with magnetic suction disc.
Connect magnetic suction disc in the described hydraulic manifold block left and right sides by web joint.
Connect magnetic suction disc in described hydraulic manifold block one side by web joint.
Be processed with 2 integrated package attachment screw holes, 4 magnetic suction disc screw connecting holes, 2 magnetic suction disc straight pin connecting holes on the described web joint, bottom at web joint is processed with arc surface, during connection, the arc surface of the bottom processing of web joint is used for mating with integrated package lateral projections position, magnetic suction disc is connected with web joint with 2 magnetic suction disc straight pins with 4 magnetic suction disc screws, with 2 integrated package attachment screws integrated package is connected with web joint again, can forms portable magnetic hydraulic pressure Brinell tester.
Compared with prior art, the beneficial effects of the utility model are:
(1) the utility model is owing to adopt the magnetic suction disc structure, make sclerometer can rely on magnetic suction disc to be adsorbed on the measured workpiece surface, neither need workpiece is supported, do not need workpiece is carried out clamping yet, only contact measured workpiece one side and can finish test, the hardness of iron and steel class workpiece that can testing large, when test power hour, adopt one-sided magnetic suction disc sclerometer, when test power is big, adopt bilateral magnetic suction disc sclerometer, and, because magnetic suction disc is adsorbed on the measured workpiece surface securely, so can effectively improve the accuracy of hardness test.
(2) the utility model is owing to adopt the reinforcing of hydraulic amplifier system, so the test power of 750kg～3000kg can be provided, can use the big ball pressure head test of 5mm or 10mm, so just can satisfy the Brinell hardness test request of most of large scale industry parts.
