Pressing and holding mechanism for leak detection of crankcase and leak detection device for crankcase

Abstract

The invention discloses a pressing and holding mechanism for leak detection of a crankcase and a leak detection device for the crankcase. The crankcase is provided with a pressing and holding point position, the pressing and holding mechanism comprises a fixing seat, a pressing block and a rotating piece; the pressing block is movably connected with the fixing seat, and the pressing block is provided with a pressing and holding part; the rotating piece is provided with a first hinge part and a second hinge part, the first hinge part is hinged to the pressing block, and the second hinge part is hinged to the fixing seat; the pressing block is provided with a first position and a second position, and the rotating piece is rotated so that the pressing block can be freely switched between the first position and the second position; when the pressing block is located at the first position, the pressing and holding part is located above the pressing and holding point position; and when the pressing block is located at the second position, the pressing and holding part is located in the side direction of the pressing and holding point position. According to the pressing and holding mechanism for leak detection of the crankcase and the leak detection device for the crankcase, through switching of the pressing block between the first position and the second position, the problem that pressing and holding cannot be carried out due to the fact that the space above the pressing and holding point position is occupied is solved.

Description

technical field [0001] The invention relates to the technical field of leak detection devices, in particular to a pressing and holding mechanism for leak detection of a crankcase and a leak detection device for a crankcase. Background technique [0002] The crankcase needs to be inspected before leaving the factory, including the inspection of leak detection items. Before the crankcase is leak tested, the crankcase needs to be pressed and held, and then the leak test is performed. [0003] However, due to the shape design of the crankcase, the space directly above the pressing point of the crankcase is occupied, and it is impossible to directly use the pressing rod to press the holding point, and thus the crankcase cannot be tested for leaks. Contents of the invention [0004] In view of the above-mentioned deficiencies of the prior art, the technical problem to be solved by the present invention is to propose a clamping mechanism for crankcase leak detection and a crankca...
