Specific embodiment
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is carried out clear, complete
Site preparation is described, it is clear that described embodiment is only a part of embodiment of the invention, rather than whole embodiments.It is based on
Embodiment in the present invention, it is every other that those of ordinary skill in the art are obtained under the premise of creative work is not made
Embodiment, belongs to the scope of protection of the invention.
As shown in Figure 1, Figure 2 and Figure 3, the embodiment of the present invention provides a kind of elbow fixture, including:Pedestal 1, pedestal 1 includes
Mutually form the lower support structure 11 and back-supported structure 12 of default angle, lower support structure 11 and back-supported structure
12 are provided with groove 13, and groove 13 is respectively used to support the two ends of elbow 2 to be clamped;Pressing plate 3, the quantity of pressing plate 3 is at least
It is 2, is movably connected with pedestal 1, and is respectively used to push down the two ends of elbow 2, make elbow 2 be fixed on pressing plate 3 and groove
Between 13;Pedestal 1 also includes mounting structure 14, and mounting structure 14 is used for the part of clamping workpiece in connecting machine tool.
Wherein, the default angle for being formed between lower support structure 11 and back-supported structure 12 is curved equal to what is clamped
First 2 angle, the groove 13 of lower support structure 11 and the groove 13 of back-supported structure 12 support to be clamped curved respectively
First 2 two ends, groove 13 make elbow 2 be difficult roll, pressing plate 3 be used for the fixed clamp of elbow 2 that will be clamped pressing plate 3 with it is recessed
Between groove 13.
Wherein, pressing plate 3 is movably connected on pedestal 1, can be designed as pressing plate and is removably connected to pedestal, or pressing plate is slided
Pedestal 1 is connected to, or press plate rotary is connected to pedestal, when elbow fixture will clamp elbow 2, is first placed in conveniently pressing plate 3
The two ends of elbow 2 are contacted the position of the groove 13 of lower support structure 11 and the groove 13 of back-supported structure 12 respectively, will be curved
After first 2 place, then pressing plate 3 is adjusted the position of the tight elbow 2 of back pressure, the position at the two ends of elbow 2 is respectively arranged with pressing plate 3, tightly
Elbow 2 is pushed down, so that elbow fixture handles the geometrical clamp of elbow 2.
The mounting structure 14 of elbow fixture can carry out respective design according to the part of clamping machine tool workpiece, so that clamping machine tool
The part of workpiece can be fixedly connected mounting structure 14, so that elbow 2 is arranged on lathe by elbow fixture, so just may be used
Elbow 2 is machined out;Generally processing screw thread is to use lathe process, the part of lathe clamping workpiece for scroll chuck or its
His fixture, by taking scroll chuck as an example, then can be made body by mounting structure 14, clamping on scroll chuck, to realize that elbow 2 leads to
Cross elbow fixture and be fixedly installed in scroll chuck, wherein make body coaxial with one end of elbow 2, just using lathe to elbow 2
One end carry out cutting thread operation, the position that the two ends of elbow 2 are clamped in elbow fixture is then exchanged again, make the other end of elbow 2
It is coaxial with body, cutting thread operation is just carried out to the other end of elbow 2 using lathe, the two ends of elbow 2 carry out screw thread respectively
After processing, just can realize that pipeline is threadedly coupled by elbow 2, it is to avoid high temperature inner tube coating when elbow 2 is with pipeline welding,
To ensure that tube body performance is unaffected.
A kind of elbow fixture provided in an embodiment of the present invention, by the groove of lower support structure, back-supported structure
Elbow fixed clamp on elbow fixture, and is fixedly connected on lathe and filled by groove and pressing plate by the mounting structure of elbow fixture
The part of workpiece is pressed from both sides, so that elbow passes through elbow fixture clamping on lathe, screw thread process is carried out to elbow two ends using lathe,
So as to realize that pipeline is threadedly coupled by elbow, it is ensured that tube body performance is unaffected.
Specifically, the open top area of groove 13 is more than bottom area, and the side wall of groove 13 is tapered plane, and tapered plane is used
In support elbow 2.Wherein, groove can be designed as deep-slotted chip breaker, but in order that elbow 2 is difficult play, need to be designed as deep-slotted chip breaker
The phase concentric of elbow 2 with clamping is more suitable, and such elbow fixture is clamped just for a kind of elbow 2 of size model number;
And groove 13, when being designed as the form in the present embodiment, groove 13 can support the elbow 2 of different size model, when groove 13 is supported
During elbow 2, the side wall of groove 13 is tangent with the outer wall of elbow 2, supports elbow 2, elbow 2 is difficult play.
Pressing plate 3 is designed as to be removably connected to pedestal 1, concrete mode is:Pedestal 1 also includes connecting pole 15, bottom branch
The both sides of support structure 11 are respectively arranged with connecting pole 15, and the both sides of back-supported structure 12 are respectively arranged with connecting pole 15,
The end of connecting pole 15 is provided with external screw thread, and through hole is provided with pressing plate 3, and through hole is used for through the end of connecting pole 15, outer spiral shell
Line is used for threaded coupling nut 4, by screw on nut 4 so that pressing plate 3 compresses elbow 2 to the direction of groove 13.When clamping elbow 2
When, pressing plate 3 is enclosed within connecting pole 15, tightens nut 4 so that the compression elbow 2 of pressing plate 3, when needing to pull down elbow 2, backs out nut
4, then pressing plate 3 can be pulled down from connecting pole 15, facilitate the dismounting of elbow 2.
Specifically, the surface for being used to push down elbow 2 in pressing plate 3 is plane.Pressing plate 3 compress elbow 2 when, the table of pressing plate 3
Face is tangent with the outer wall of elbow 2, and the surface of pressing plate 3 is plane, can compress the elbow 2 of different size model.
For the elbow 2 clamped by more preferable centering, pedestal 1 also includes two relative side plates 16, lower support structure
11st, back-supported structure 12 and two side plates 16 surround grasping part, and centering structure 161 is respectively arranged with two side plates 16;
When the elbow 2 to be clamped is placed in grasping part, and the two ends of elbow 2 are clamped in when between pressing plate 3 and groove 13 respectively, right
Middle structure 161 is used to adjust distance of the elbow 2 relative to side plate 16.Wherein, centering structure 161 can be designed as relative side plate 16
To the structure promoted in grasping part, when elbow 2 is clamped, the centering structure 161 of biside plate 16 can be towards mutually drawing close
Direction promotes elbow 2, elbow 2 is clamped between two side plates 16, more improves the clamping fastener of elbow 2.
Specifically, centering structure 161 includes screwed hole, and screwed hole internal thread attachment screw promotes curved by screwing screw
First 2 with adjust elbow 2 with respect to side plate 16 distance.Hole is threaded on side plate 16, in the screwed hole on biside plate 16 respectively
Screw is screwed in clamp clamped elbow 2, simple structure is easily realized.
Elbow fixture can be designed as it is fixed or adjustable, wherein fixed is lower support structure 11 and back
The angle of supporting construction 12 is fixed, and the adjustable angle for lower support structure 11 and back-supported structure 12 can adjust, tool
Body design is as follows:
When elbow fixture is designed as fixed, referring to Fig. 2, lower support structure 11 includes base plate and is arranged on base plate
