Description
Technical field
The utility model is related to field of fixtures, more particularly to a kind of fixture of dish type thin wall component.
Background technology
Fixture refers to that machine-building is used for fixing processing object in the process, is allowed to occupy correct position, to receive construction
Or the device of detection.Scroll chuck is fixture common in the market, is made of chuck body, movable jaw and claw driving mechanism,
Driving mechanism includes dish-shaped bevel gear and is set to the flat thread at the dish-shaped bevel gear back side, three claws and dish on scroll chuck
The flat thread at the shape bevel gear back side matches, when rotating cone pinion by square hole with spanner, dish-shaped gear rotation, and the back of the body
The flat thread in face drives three claws close or exit to center simultaneously, to clamp different-diameter part side wall.But
When the part of dish type thin wall is clamped, since the feature side-wall area of dish type thin wall is smaller, lead to three of scroll chuck
The contact area of claw and part is smaller, causes part in process to be easy to be detached from claw, makes part that can not continue to process.
The Chinese utility model patent that notification number is CN201988970U disclosed a kind of for disk on the 28th in September in 2011
The fixture of type thin wall component processing.Including ring flange and negative pressure sucker；Negative pressure sucker is fastened by chassis and sucker, the bottom of at
It is equipped with cavity between disk and sucker, multiple through-holes being connected to cavity are offered on sucker；On chassis with ring flange center
The corresponding position in hole is provided with the air entry being connected with ring flange center hole；Ring flange and the lateral surface on chassis, which are fixed, to be joined
It connects.The cavity of external pumped vacuum systems and negative pressure sucker is connected to form vacuum loop, the one side of part when vacuum loop is connected
It fits with sucker face, forms negative pressure of vacuum among part and sucker face, atmospheric pressure will be pressed in part on sucker face.
But when needing that the part of small volume or surface irregularity is clamped, through-hole is possible to meeting and atmosphere, causes
Negative pressure of vacuum among part and sucker face weakens, and the stability of part is made to reduce.Therefore there is a problem of that stability is poor.
