Description
Technical field
The utility model belongs to technical field of mechanical processing, and in particular to a kind of auxiliary device that turning conduction is stifled.
Background technology
It is blocked up in process in equipment conductions such as pumping plant, coal machines, since conduction is stifled complex-shaped, when turning need to use four paws
Certain machined surface is clamped to be fixed in chuck, then can carry out turning with top hold out against, but chuck centering is difficult,
The problems such as often causing to do over again because of guide pin position deviation, scrapping, moreover, the complete conductive stifled position of turning needs later
Again clamping, adjustment direction, centering carry out the turning at next position, can not one-pass molding, thus, developing one kind simply has
The stifled auxiliary device of the turning conduction of effect, solves the problem of conductive stifled centering it is difficult can not one-pass molding, reduce rework rate, report
Useless rate is highly important.
Utility model content
The purpose of this utility model is to provide a kind of auxiliary device that turning conduction is stifled, solves existing in the prior art
Four paws chuck is difficult to make conductive stifled blank centering, and can not one-pass molding, ineffective problem reduces scrappage, returns
Work rate.
The utility model is the technical scheme adopted is that a kind of stifled auxiliary device of turning conduction, including chuck and tooling.
Tooling includes tail portion positioning pin, pallet and workpiece positioning pin, and tail portion positioning pin is located at pallet lower surface, and pallet is positioned with tail portion
Overlapping fixes as one pin up and down.Workpiece positioning pin is located at tray upper surface, and workpiece positioning pin is be overlapped affixed up and down with pallet
It is integrated.Position in its center is clamped in tail portion positioning pin by chuck.
The utility model is also characterized by：
Chuck is scroll chuck.
Tail portion positioning pin is cylinder, and the axis of the center of circle of tail portion positioning pin and pallet is on the same line.
Pallet is cylinder.
There are two workpiece positioning pins, and is cylinder, and height is less than or equal to standard conductive and blocks up large hole in stepped hole
Highly, diameter is equal to the diameter that standard conductive blocks up large hole in stepped hole, and two workpiece positioning pins are at least the one of pallet
The distance of center circle of a symmetrical axial symmetry, two workpiece positioning pins is equal to the distance of center circle that standard conductive blocks up two stepped holes.
The utility model has the beneficial effects that：It is conduction that tooling in the utility model, which makes workpiece turning, can make when stifled
With scroll chuck, scroll chuck can self-centering therefore solve the problems, such as that by workpiece turning, centering is difficult when being conductive stifled,
To reduce rework rate and scrappage, also, when being conductive stifled by workpiece turning, scroll chuck clamping tooling need to be used, then
The cooperation of the stepped hole of workpiece is inserted into the workpiece positioning pin of tooling, then can turning with top hold out against of fixture, it is not necessary to be clamped one
Fixed machined surface, it is conductive stifled that can make workpiece one-time turning, in this way, improving work efficiency.

Part positioning pin.
Specific implementation mode
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in Figure 1, the auxiliary device that the utility model turning conduction is stifled, including chuck 1 and tooling 2, chuck 1 is can be certainly
The scroll chuck of dynamic centering.
As shown in Fig. 2, the tooling 2 of the stifled auxiliary device of the utility model turning conduction, including cylinder tail portion positioning pin
21, cylinder pallet 22 and two cylindrical workpiece positioning pins 23, the diameter of pallet 22 are more than the diameter of tail portion positioning pin 21, tail
The diameter of portion's positioning pin 21 is more than the diameter of workpiece positioning pin 23, and tail portion positioning pin 21 is located at the centre bit of 22 lower surface of pallet
It sets, the axis of axis and pallet 22 is on same straight line, and pallet 22 is Chong Die with about 21 tail portion positioning pin is welded as one
Body.Two workpiece positioning pins 23 are located at 22 upper surface of pallet, and it is Chong Die with about 22 pallet be welded as a whole, the positioning of two workpiece
Pin 23 is centrosymmetric with the center of circle of pallet 22.
As shown in figure 3, the conduction that the auxiliary device turning to be blocked up with the utility model turning conduction goes out blocks up finished product, including platform
Rank hole 5, the enlarged drawing of sectional view is as shown in figure 4, the height of workpiece positioning pin 23 is larger less than or equal in conductive stifled stepped hole 5
The height in hole, diameter is equal to the diameter of large hole in conductive stifled stepped hole 5, and the distance of center circle of two workpiece positioning pins 23 is equal to
Conduction blocks up the distance of center circle of two stepped holes 5.
The application method of the stifled auxiliary device of the utility model turning conduction is first to drill out workpiece 4 on bored machine
The stifled stepped hole 5 of conduction, then installs scroll chuck 1 on lathe, then uses the tail portion of 1 clamping tooling 2 of scroll chuck fixed
Position pin 21, because scroll chuck 1 can self-centering, therefore, the center of lathe, the center of scroll chuck 1 and tooling 2 center same
On one straight line, then the stepped hole 5 that conduction is blocked coordinates the workpiece positioning pin 23 for being inserted into tooling 2, then uses the top top of fixture 3
Clamping of workpieces 4, the face to be processed of last turner, until finished product conduction is stifled.
The distance of center circle of two tail portion positioning pins 21 of tooling 2 is standard in the stifled auxiliary device of the utility model turning conduction
Conduction blocks up the distance of center circle of two stepped holes 5, and therefore, tooling 2, which also functions to, examines whether the stepped hole 5 bored on workpiece 4 complies with standard
Effect, if stepped hole 5 can not coordinate be inserted into tooling 2 tail portion positioning pin 21, then, you can give up, it is not necessary to carry out following
Process, in this way, improving work efficiency.
