Background technology
During smart car, seal groove and cylindrical axiality are intended to for the sleeve of multi-stage oil cylinder, piston cylinder and cylinder body
Ask and reach within 0.05mm.Conventional process technique, often change a three-jaw, can only clamping one-level sleeve, and every time
Again to correct claw ensures axiality requirement, and operation is loaded down with trivial details, and efficiency is low, so not only significantly influences production efficiency
And increase worker produces intensity, during using customer demand as the small serial production being oriented to, people's multi-machine operation can not be realized,
Serious waste human resources.
Utility model content
The purpose of this utility model is to provide a kind of three-jaw that can quickly change the mold, and different model is switched fast to realize
The number car auxiliary mould of the smart car requirement of multi-stage oil cylinder, can quickly be realized not at the same level by the hard alloy blocks changed on three-jaw
Other sleeve is switched fast.Compared with traditional handicraft, reduce and change more than three-jaw body time 10min, and eliminate switching
During change amendment three-jaw process.Several car auxiliary moulds provided by the utility model not only improve production efficiency, Er Qieyou
Effect ensure that the axiality of groove is shown in cylindrical and sealing.Concrete scheme is as follows：
A kind of number car auxiliary mould quickly changed the mold, for the processing of steel pipe workpieces, includes pawl disk, in the pawl disk
Outer face and its center of circle is provided with some movable jaws, each claw have extended axially forward along pawl disk it is step-like
Extension；
The step-like extension of each claw includes a positioning step, each positioning step and the pawl dish axle heart
Distance it is identical, dismountable fixed block is installed, the outer rim of the fixed block is song on the positioning step of each claw
Face；
The internal diameter of the steel pipe workpieces is set on the fixed block on the claw, by the fixed block for changing different size
To be adapted to the steel pipe workpieces of installation different inner diameters.
Further, 3 movable jaws are provided with the outer face of the pawl disk and around its center of circle.
Further, the fixed block is arranged on by screw on the positioning step of claw.
Compared with prior art, the beneficial effects of the utility model are：
The utility model is simple in construction, easy to operate, practical, both improves efficiency, alleviates labor intensity again, by this
When frock changes different sleeves, cylinder body, piston cylinder, it can ensure machining accuracy with fast positioning, can easily realize that a people is more
The operation of machine.
Brief description of the drawings
, below will be to embodiment or prior art in order to illustrate more clearly of the technical scheme in the embodiment of the utility model
The required accompanying drawing used is briefly described in description, it should be apparent that, drawings in the following description are only that this practicality is new
Some embodiments of type, for those of ordinary skill in the art, without having to pay creative labor, can be with
Other accompanying drawings are obtained according to these accompanying drawings.
Fig. 1 is a kind of schematic diagram of the number car auxiliary mould end face quickly changed the mold provided by the utility model；
Fig. 2 is the side view of number car auxiliary mould；
Fig. 3 is the sectional view of the utility model fixed block in one embodiment.
Embodiment
In the following description, a large amount of concrete details are given more thoroughly to manage the utility model to provide
Solution.It is, however, obvious to a person skilled in the art that the utility model can be without one or more of these thin
Save and be carried out.In other examples, in order to avoid obscuring with the utility model, for more well known in the art
Technical characteristic is not described.
In order to thoroughly understand the utility model, detailed step and detailed structure will be proposed in following description,
To explain the technical solution of the utility model.Preferred embodiment of the present utility model is described in detail as follows, but except these
Outside being described in detail, the utility model can also have other embodiment.
The utility model provides a kind of number car auxiliary mould quickly changed the mold, for the processing of steel pipe workpieces, includes
Pawl disk, as Figure 1-3, some movable jaws 1, each claw are provided with the outer face of the pawl disk and around its center of circle
1 has the step-like extension extended axially forward along pawl disk；The step-like extension of each claw 1 includes necessarily
Position step, each positioning step is identical with the distance of the pawl dish axle heart, is provided with the step of each claw 1 dismountable
Fixed block 3, the outer rim of the fixed block 3 is curved surface；
The internal diameter of the steel pipe workpieces is set on the fixed block 3 on the claw 1, by the fixation for changing different size
Block 3 installs the steel pipe workpieces of different inner diameters to be adapted to.Optionally, fixed block 3 is hard alloy blocks.As shown in Fig. 2 claw 1 has
There is the step-like extension extended axially forward along pawl disk, the step-like extension has 3 steps, and we are fixed for the step at middle part
Justice is positioning step, for installing fixed block 3.
