It is processing to be fixed by folder excircle of workpiece, but this processing method causes the verticality of each slot and hole and lower planes cannot get
Guarantee.
Utility model content
It, can be with the main purpose of the utility model is to provide a kind of multiple workpieces Throttle valve device in center easy to process
Effectively solve the problems in background technique.
To achieve the above object, the technical solution that the utility model is taken are as follows:
A kind of multiple workpieces Throttle valve device in center easy to process, including bottom plate, the bottom plate are fixed on machining center
Table top is processed in recessed stepped hole certainly, and the upper end of the bottom plate is equipped with pedestal, and the pedestal is equipped with multiple from processing step hole, institute
It states from processing step hole and workpiece to be processed outer circle slide fit, the pedestal upper end is equipped with pressing plate, and the pressing plate is equipped with multiple second
Stepped hole and the die hole being arranged in above second step hole, and second step hole also with workpiece to be processed outer circle clearance fit,
Concentric mandrel is equipped among the pressing plate and pedestal, the bottom of the mandrel is connect with bottom plate, on the mandrel of the pressing plate lower end
It is cased with spring.
Further, the pedestal from the sum of second step hole depth of processing step hole depth and pressing plate be less than it is to be added
Work thickness of workpiece.
Further, the slide fit gap width is 0.01-0.02mm, clearance fit gap width are as follows: 0.05-0.10mm.
Further, the mandrel upper end is adjusted by nut and is fixed.
Further, described identical with the number in second step hole from processing step hole, and be 3.
Compared with prior art, the utility model has the following beneficial effects:
By the implementation of the present apparatus, solves the processing of each hole in throttling valve body end face and slot, ensure that throttling valve body
The position precision of end-face hole and slot and end face is avoided and is scrapped because verticality is overproof, while disposable clamping three, is improved
If necessary multiple present apparatus can also be arranged in working efficiency, not only ensure that precision, but also improve efficiency.

Specific embodiment
To be easy to understand the technical means, creative features, achievement of purpose, and effectiveness of the utility model, below
In conjunction with specific embodiment, the utility model is further described.
As shown in Figs. 1-2, a kind of multiple workpieces Throttle valve device in center easy to process, including bottom plate 1, the bottom plate 1
It is fixed on processing in recessed stepped hole certainly for machining center table top, the upper end of the bottom plate 1 is equipped with pedestal 2, and the pedestal 2 is equipped with more
It is a that from processing step hole 3, described from processing step hole 3 and workpiece to be processed outer circle slide fit, 2 upper end of pedestal is equipped with pressing plate 4,
The pressing plate 4 is equipped with multiple second step holes 5 and the die hole 6 of 5 top of second step hole is arranged in, and second step hole 5
With workpiece to be processed outer circle clearance fit, be equipped with concentric mandrel 7 among the pressing plate 4 and pedestal 2, the bottom of the mandrel 7 with
Bottom plate 1 connects, and is cased with spring 8 on the mandrel 7 of 4 lower end of pressing plate.
Wherein, the pedestal 2 from the sum of 3 depth of processing step hole and 5 depth of second step hole of pressing plate 4 be less than it is to be added
