This practical theory of operation: this an anchor clamps structure for aluminium die-casting valve gap precision finishing, when using, at first the valve gap texture is even, and when the shape is even, overlaps the protruding part of valve gap downwards in the through-hole in support plate 4 middle part to make the downward surface of valve gap all mutually support with the end at thimble 505 top.
When the valve cover extrudes the thimble 505 due to its own gravity, the thimble 505 moves downward to drive the wedge 504 connected thereto to move downward, the inclined surface of the wedge 504 and the surface of the wedge 503 slide relatively to each other, so that the downward pressure is changed into a horizontal force application effect, and the positioning plate 501 is driven to generate a horizontal deviation action, so that the wedge 504 on the opposite side of the downward wedge 504 moves upward, the upward moving wedge 504 drives the thimble 505 connected thereto to move upward, and the upward moving thimble 505 abuts against the surface of the valve cover to drive the side of the valve cover to move upward, thereby causing the valve cover to be gradually leveled under the influence of its surface gravity.
The thimble 505 not only provides the holding power for the valve gap when loading, more can provide the quick leveling operation that relies on gravity to realize for the valve gap of the even shape symmetry of texture, has also realized the valve gap and has loaded the position and fix a position.
The contact area of thimble 505 and valve gap is less for the valve gap is difficult to receive dust and the impurity that the support contact surface adheres to influence its setting height, and the effectual assembly counterpoint that has ensured makes the machining precision of valve gap higher.
