Abstract
The invention discloses a drawing device used for disassembly of a hole and shaft interference fit product, and belongs to the field of engineering machinery. The drawing device mainly comprises a drawing device body, a bolt, a pin, a claw, a stud and a pushing cover, wherein a central via hole is machined in the drawing device body, and a thread is formed in the central via hole; the claw is rotationally connected with the drawing device body through the pin and limited through the bolt; the stud is connected with the central via hole in the drawing device body through thread fitting; the pushing cover is an independent part and abuts against the lower end surface of the stud during use. The drawing device is simple in structure, reasonable in layout, and capable of successfully realizing disassembly of the hole and shaft interference fit product, and saves time and labor in the operation process.
Description
Technical field
The present invention relates to a kind of drawing, belong to engineering machinery field.
Background technology
Certain type fanjet is common hole axle interference fit products, and it is mainly by first turbine dish and two grades
The turbine disk is consisted of hole axle interference fit, and described first turbine dish is provided with internal channel structure；At its point
Solving in operation, owing to first turbine dish and two-stage turbine dish are hole axle interference fit, decomposing force is relatively big, inhuman
Power in one's power, can not use the methods such as percussion product, otherwise product can be caused damage.
Therefore, in order to realize the reliable decomposition of hole axle interference fit products, need to design special drawing frock.
Summary of the invention
In view of this, it is an object of the invention to provide a kind of drawing decomposed for hole axle interference fit products
Device, described drawing structure is simple, rationally distributed.
The purpose of the present invention is realized by techniques below scheme:
A kind of draw-off gear decomposed for hole axle interference fit products, described draw-off gear mainly includes drawing
Device main body, bolt, pin, claw, stud and top cover；Wherein, in described drawbench main body being machined with
Heart via, and described center via is provided with screw thread；
Described claw is connected with described drawbench body rotation by pin, and carries out spacing by bolt；Institute
State stud to be connected by threaded engagement with the center via in drawbench main body；Described top cover is separate piece, makes
Conflict in the lower surface of used time and stud.
Further, described bolt is M8X35 bolt.
Further, described pin is A8X50 pin.
Further, the number of described claw, bolt and pin is 3.
Beneficial effect
Draw-off gear simple in construction of the present invention, rationally distributed；By bolt and the cooperation of pin, it is ensured that
Claw can do a range of flexible expansion and adjust, it is achieved that with being reliably connected of product to be decomposed, and close
Reason uses the screw thread lift of stud, by the thrust of top cover, successfully achieves hole axle interference fit products and divides
Solve, and operating process is time saving and energy saving.
Accompanying drawing explanation
The structural representation of Fig. 1 draw-off gear of the present invention；
The graphics of Fig. 2 draw-off gear of the present invention；
Wherein, 1-drawbench main body, 2-bolt, 3-pin, 4-claw, 5-stud, 6 top covers.
Detailed description of the invention
The present invention is described in detail in detail with specific embodiment below in conjunction with the accompanying drawings, but is not limited to this.
Embodiment 1
As illustrated in fig. 1 and 2, a kind of draw-off gear decomposed for hole axle interference fit products, described drawing
Device mainly includes drawbench main body 1, bolt 2, pin 3, claw 4, stud 5 and top cover 6；Wherein,
It is machined with center via in described drawbench main body 1, and described center via is provided with screw thread；
Described claw 4 is rotationally connected with described drawbench main body 1 by pin 3, and is carried out by bolt 2
Spacing；Described stud 5 is connected by threaded engagement with the center via in drawbench main body 1；Described top cover 6
For separate piece, during use, conflict in the lower surface with stud 5.
Further, described bolt 2 is M8X35 bolt.
Further, described pin 3 is A8X50 pin.
Further, the number of described claw 4, bolt 2 and pin 3 is 3.
Work process is as follows: first by first turbine dish endoporus, part top cover 6 is positioned over two-stage turbine dish
Center, then unclamps bolt 2, is rotated along pin 3 by claw 4, receives in making claw 4 lower end,
Putting into first turbine dish, then tightened successively by three bolts 2, now, claw 4 lower end extends out and embedding
Enter in first turbine dish internal channel, stud 5 is rotated down, until conflicting with top cover 6 in stud 5 lower surface,
Then proceed to be rotated down stud 5, now embed the claw 4 of first turbine dish internal channel gradually by first turbine
Dish is extracted from two-stage turbine dish, until first turbine dish thoroughly separates with two-stage turbine dish.
The present invention includes but not limited to above example, every carry out under the principle of spirit of the present invention appoint
What equivalent or local improvement, all will be regarded as within protection scope of the present invention.
