Cooperation schematic diagram, 200 one end connecting chainring 300 of mandrel, (the i.e. hole of matched hole on flat end insertion fluted disc 300
Section is identical with flat end cross-sectional shape).Centrifuge arm 400 is rotatably arranged on fluted disc 300, and 400 one end of centrifuge arm is equipped with
Slot 401 is stirred, the other end passes through hook spring (not shown) connecting mandrel 200.500 one end of driving lever is inserted and secured on driving lever jack
In 102, other end insertion is stirred in slot 401, and centrifuge arm 400 carrys out back rotation under the action of mandrel 200 and tension spring, to drive
Pressure reducing valve 100 carrys out back rotation.
It processes the pressure reducing valve 100 and usually first processes flat 101, then boring driving lever jack 102, traditional manufacturing technique
In, be all by being manually cut to flat 101, the flat being manually cut into, length is inconsistent, the fore-and-aft plane cut out from
The distance of axis is inconsistent, and processing efficiency is low, can only once cut a pressure reducing valve.
Utility model content
The utility model proposes a kind of pressure reducing valve flat cutting jig, solves pressure reducing valve in the prior art and manually cut effect
Rate is low and the length of flat is inconsistent, the inconsistent problem of the distance of the off-axis line of the fore-and-aft plane cut out.
A kind of pressure reducing valve flat cutting jig of the utility model, comprising: pedestal, it is uniform along base axis on the pedestal
Distribution ground is equipped at least two fixture blocks, and gap is equipped between two neighboring fixture block, and each fixture block bottom and the pedestal connect
It connects, top is formed with protrusion, and all fixture blocks form one using base axis as the circular clamp portion of axis, the protrusion side
Wall and top surface form ring-shaped step, and two fixture block side walls of each gap two sides, which are each formed with, extends into protrusion
Arc receiving hole, two opposite arc receiving holes are collectively formed round receiving hole, the axis of the circle receiving hole with it is described
The radial direction in circular clamp portion is consistent, and is generally aligned in the same plane, which is parallel to circular clamp portion top surface, the circle
Shape receiving hole is formed with the axial gap of the axis direction along round receiving hole at ring-shaped step.
Wherein, the fixture block and pedestal are integrally formed.
Wherein, the circular clamp portion is hollow ring.
The pressure reducing valve flat cutting jig of the utility model can improve processing with the more than two pressure reducing valves of time processing
Efficiency, and it is each it is round accommodate that hole depth is consistent, and be formed at ring-shaped step axis direction along round receiving hole
The axis of axial gap, all circle receiving holes is respectively positioned on same plane, which is parallel to circular clamp portion top surface, from
And flat length is consistent after ensure that cutting, the distance of the off-axis line of the fore-and-aft plane cut out is consistent.
Detailed description of the invention
In order to illustrate the embodiment of the utility model or the technical proposal in the existing technology more clearly, below will be to embodiment

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without creative efforts
Every other embodiment obtained, fall within the protection scope of the utility model.
The pressure reducing valve flat cutting jig of the present embodiment is as seen in figures 3-5, comprising: pedestal 1, along pedestal on the pedestal 1
1 axis is evenly distributedly equipped at least two fixture blocks 21, is equipped with gap 3, each fixture block 21 between two neighboring fixture block
Bottom is connect with the pedestal 1, and top is formed with protrusion 22, and all fixture blocks 21 form one using the axis of pedestal 1 as axis
Circular clamp portion 2,22 side wall of protrusion and top surface form ring-shaped step, two fixture blocks of each 3 two sides of gap
21 side walls are each formed with the arc receiving hole for extending into protrusion 22, and round receiving is collectively formed in two opposite arc receiving holes
Hole 4, the axis of round receiving hole 4 is consistent with the radial direction in the circular clamp portion 2, and is generally aligned in the same plane, and the plane is flat
For row in 2 top surface of circular clamp portion, round receiving hole 4 is formed with the axis direction along round receiving hole at ring-shaped step
Axial gap.
In Fig. 3~5, fixture block 21 is two, can once process two pressure reducing valves, certain fixture block 21 can be two with
On, such as: 3,4 or 8, fixture block more than 21, i.e., round receiving hole more than 4, the pressure reducing valve that can disposably process is more, adds
Work efficiency rate is higher.
Before processing, cylinder to be processed is inserted into round receiving hole 4, circular clamp portion 2 is clamped using lathe dog, i.e.,
Gap 3 reduces, so that cylinder to be processed is fastened in round receiving hole 4,2 top of circular clamp portion is lived on the lathe top crown, opens
Motor-car bed rotates circular clamp portion 2, cutter is stretched at ring-shaped step, since round receiving hole 4 is formed at ring-shaped step
There is the axial gap of the axis direction along round receiving hole, a part of side wall of cylinder to be processed is cut away outside being exposed to by cutter
Form flat.In the present embodiment, each circle 4 depth of receiving hole is consistent, and is formed at ring-shaped step along round receiving hole 4
Axis direction axial gap, it is all circle receiving holes 4 axis be respectively positioned on same plane, which is parallel to circular clamp
2 top surface of portion, so that flat length is consistent after ensure that cutting, the distance of the off-axis line of the fore-and-aft plane cut out is consistent.
In the present embodiment, fixture block 21 and pedestal 1 are integrally formed, and globality is strong, and structure is firmer.
In the present embodiment, circular clamp portion 2 is hollow ring, materials is saved when making the tooling, weight is lighter.
The above is only the preferred embodiment of the present invention, is not intended to limit the utility model, all practical at this
Within novel spirit and principle, any modification, equivalent replacement, improvement and so on should be included in the guarantor of the utility model
