Clamping device of blade type precision forging part

Abstract

The invention provides a clamping device of a blade type precision forging part. The device comprises a guide rail base, a fixing clamping end component and a mobile clamping end component, wherein the fixing clamping end component comprises a fixing end sliding block, a fixing end cover, a fixing end body and a plurality of positioning claws, and the mobile clamping end component comprises a main mobile end sliding block, a mobile end pushing component, a mobile end cover, a mobile end body and a plurality of positioning claws. According to the device, a plurality of positioning claws with pressure springs forms needle field type flexible clamping, when a complex part is clamped, a positioning claw at the position of the part moves towards a groove of the fixing end cover or the mobile end cover along a through-hole on a gasket, positioning claws at other positions can be formed along the geometrical shape of the outline of a part, a fixing end kidney-shaped pressing plate and a mobile end kidney-shaped pressing plate are fixed tightly through a fixing end kidney-shaped pressing plate pressing device and a mobile end kidney-shaped pressing plate pressing device, and the kidney-shaped pressing plates at two ends press the positioning claws on two ends respectively, so that the outline of the part can be maintained, and the part can be clamped.

Description

technical field [0001] The invention relates to the mechanical field of mechanical clamping devices, in particular to a clamping device for blade precision forging parts. Background technique [0002] Before the inspection of fine forged blade wool, it is necessary to allow the same batch of blades to have a definite position to be inspected relative to the white light scanning inspection equipment, so that the inspection conclusions of the same batch of wool have similar consistency. In the past, small flat-mouth vises were used to clamp parts for positioning. Since the jaws of the flat-mouth vise do not have the function of determining the unique position of the blade, each time a blade is inspected, the blade must be manually adjusted to an almost position that cannot be accurately measured. Due to the large batch of fine forging wool for blades, the labor intensity very big. Moreover, the white light scanning detection equipment belongs to non-contact measurement, and ...

Problems solved by technology

Since the jaws of the flat-mouth vise do not have the function of determining the unique position of the blade, each time a blade is inspected, the blade must be manually adjusted to an almost position that cannot be accurately measured. Due to the large batch of fine forging wool for blades, the labor intensity very big

Moreover, the white light scanning detection equipment belongs to non-contact measurement, and the measurement accuracy is greatly affected by the initial position of the parts. The same batch of blade wool is random due to the manual adjustment of the initial position deviation of the parts, which increases the interference factor. The white light scanning detection equipment itself cannot compensate and correct this. The initial position error, so the randomness of the initial position deviation of the parts affects the judgment of the inspection conclusion, resulting in poor consistency of the inspection conclusions of the same batch of blade wool, and the quality of the blade inspection is unstable

In short, the existing detection clamping scheme is time-consuming and laborious to operate, the detection efficiency is extremely low, and it is easy to cause false detection

The above problems have brought great difficulties to the detection of fine forging blade blanks. It is necessary to design a special clamping device for such blade parts with complex geometric shapes that are difficult to locate to solve the above problems.
