Description

Technical Field

[0001] The invention relates to the field of auxiliary tool design and manufacturing, and in particular to an auxiliary tool for testing oil guide plate parts. Background Art

[0002] The oil guide plate is an important component of the steering gear of the armored vehicle transmission. This part requires an oil pressure test after welding. The test oil pressure is required to be no less than 1.5MPa, and the pressure holding time is no less than 10min. No leakage is allowed during the test. Since the pressure test part of this part is difficult to seal, it is difficult to perform a sealing test using traditional test sealing aids. Therefore, how to design a set of oil guide plate pressure test sealing aids to solve the sealing performance of the oil guide plate is an urgent problem that oil guide plate manufacturers need to solve. The present invention can solve the problem of pressure test sealing of similar oil guide plates after welding, and facilitate the sealing detection of the weld of the oil guide plate. Summary of the invention

[0003] In view of the shortcomings of the above-mentioned existing pressure test sealing auxiliary tools, the present invention provides an oil guide plate part test auxiliary tool to solve the problems of similar oil guide plate weld sealing tests.

[0004] The technical solution adopted by the present invention is: An auxiliary tool for testing oil guide plate parts, comprising bolts, washers, cover plates, rubber plates, plugs, balancing pads, O-rings, sealing grooves, oil through grooves, bases, nuts and oil inlet joints. The O-rings are inserted into the sealing grooves of the bases, the bases are inserted into the inner holes of the oil guide plate, the bases and the O-rings and the oil guide plate parts to be pressure tested form an interference fit, the plugs are pressed into the holes of the oil guide plate, the balancing pads are evenly distributed on the upper end surface of the oil guide plate, the rubber plates cover the upper ends of the plugs and the balancing pads, the cover plates cover the rubber plates, the washers are inserted into the bolts, the bolts are tightened to the bases, the cover plates and the bases are locked, an oil through groove is provided on the bases, and the oil inlet joints are welded to the oil through grooves.

[0005] Furthermore, a nut is welded at the center of the bottom of the base, and is used to remove the base from the oil guide plate after the pressure test is completed.

[0006] Furthermore, the oil inlet joint is welded at the center hole position of the oil groove.

[0007] Furthermore, the oil passage groove is used to pass the pressure test oil into the oil guide plate to perform a pressure test.

[0008] Furthermore, a threaded hole is provided at the center of the upper end surface of the base for locking the cover plate, the rubber plate, the plug and the balance pad.

[0009] Furthermore, two sealing grooves are provided at the center of the outer circle of the base for installing O-rings for sealing.

[0010] Furthermore, the material of the rubber sheet is A7-8H5Hr1Tb2.

[0011] During operation, insert two O-rings into the two sealing grooves of the base, and then insert the base into the inner hole of the oil guide plate. The base, O-rings and the parts of the oil guide plate to be pressure tested form an interference fit. Then press the plug into the hole of the oil guide plate. According to the position and height of the plug, evenly distribute the balance pad on the upper end of the oil guide plate. Then cover the rubber plate on the plug and the upper end of the balance pad, and then cover the cover on the rubber plate. Then insert the gasket into the bolt, and tighten the bolt into the base, and lock the cover and the base together to achieve the locking effect. Finally, pass oil from the oil inlet interface to perform an oil pressure test on the weld of the oil guide plate. After the test is completed, remove the base from the inner hole of the oil guide plate through the nut.

[0012] The beneficial effects of the present invention are: (1) The present invention has a simple structure, is easy to manufacture and has low cost; (2) The present invention can use the pressure test seal auxiliary device to perform a sealing test on similar oil guide plates; (3) The present invention can effectively seal the welded oil guide plate, so that the detection result of the welded oil guide plate is accurate and reliable.
