Embodiment Construction
[0022] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.
[0023] Such as figure 1 As shown, a structure of an oil distribution plate 1 is shown. The oil distribution plate 1 has seven flow channels and four central axis vent holes 1.1, and each flow channel corresponds to a side vent hole 1.2 and an upper vent hole 1.3 or A lower air hole 1.4, these air holes need to be blocked when doing the air tightness test before testing.
[0024] Such as figure 2 As shown, an air tightness detection device for an oil distrib...

The invention discloses an air tightness detection device for an oil distribution disc. The device comprises a bottom plate, the bottom plate is provided with a fixing assembly for positioning the oildistribution disc, a plugging assembly for plugging a vent hole of the oil distribution disc, and a pull-down assembly, and an upper pressing assembly for pressing the oil distribution disc is disposed above the bottom plate. During detection, the oil distribution disc is positioned on the bottom plate through the fixing assembly, the upper pressing assembly is used for pressing and fixing the oil distribution disc, the plugging assembly and the pull-down assembly are used for plugging all the vent holes of the oil distribution disc, finally, testing is performed, a result is compared with anumerical value measured by a standard qualified product, and a conclusion is made by comparing a test result. The detection device can be used after the oil distribution disc is qualified, the safetyis ensured, the detection is convenient, and the efficiency is high.
Description
technical field [0001] The invention relates to the technical field of auto parts, in particular to an air tightness detection device for an oil distribution plate. Background technique [0002] The oil distribution plate, in the hydraulic motor or pump, plays the role of high and low oil circuit distribution, so that when the high pressure oil in the motor or pump acts on the output torque, when the low pressure oil (oil return) discharges the high pressure oil in the plunger chamber that stops the output torque . [0003] The existing oil distribution plate is a casting. Due to its many internal flow channels and complex structure, it is prone to casting defects such as leaks and adjacent oil passages. It needs to be tested for air tightness to ensure that the oil distribution plate is qualified. products can be used. Contents of the invention [0004] In view of the above-mentioned problems existing in the prior art, it is intended to provide an airtightness detection...
