Description of reference numerals: the valve body clamping device comprises a base 1, a valve body support 2, a fulcrum bolt 3, a rocker arm 4, a connecting rod 5, a first ejector rod 6, a second clamping arm 7, a second ejector rod 8, a first clamping arm 9, a positioning plate 10, a supporting block 11, a clamping block 81 and an arc-shaped groove 82.

Detailed Description

The utility model will be further described with reference to examples in the drawings to which:

as shown in the figure, a frock for exhausting tone tuning valve clearance test, includes the ascending frock base 1 of horizontal direction, the middle part of base 1 is provided with valve body support 2, and the three first tight arm 9 of clamp of equipartition around valve body support 2, the tip level of first tight arm 9 of clamp is provided with first ejector pin 6, and the side of valve body support 2 still is provided with supporting shoe 11, the top of supporting shoe 11 is provided with the tight arm 7 of second clamp, the vertical second ejector pin 8 that is provided with of the tip of the tight arm 7 of second clamp, first tight arm 9 of clamp is the same with the structure of the tight arm 7 of second clamp.

First clamp arm 9 includes locating plate 10, be provided with fulcrum bolt 3, rocking arm 4 and connecting rod 5 on the locating plate 10, rocking arm 4 is through the connecting rod 5 of round pin hub connection level setting, connecting rod 5 is connected with first ejector pin 6, and rocking arm 4 uses the fulcrum bolt 3 of level setting to move in the vertical plane as the axle setting, drives connecting rod 5 and first ejector pin 6 simultaneously and stretches out and draws back on the surface of water direction.
