Specific embodiment
With reference to the accompanying drawing, it elaborates to the utility model:
As shown in Figure 1 and Figure 2, a kind of nozzle ring of the utility model core setting machine structure, for by mounting disc 7, spacing pin 8
And the assembled combination workpiece of bushing 9 is gripped.
The utility model core setting machine structure, including determine core expander 4, collet chuck 5, ring flange 2 and movable expander 6.Determine core
Expander 4 is fixed in ring flange 2, and 6 sets of movable expander is being determined in core expander 4 and can be along the inner hole for determining core expander 4
Lower movement.
It is machined with a tapered squeezing face 61 on movable expander 6, is machined with the first guiding conical surface determining core expander 4
41, referring to Fig. 3 and Fig. 5.Taper compression face 51 and one that one cooperates with tapered squeezing face 61 is machined on collet chuck 5 to expand with core is determined
The second guiding conical surface 52 that the first guiding conical surface 41 of device 4 cooperates is opened up, sees Fig. 4.Tapered squeezing face 41 and the first guiding conical surface 41
Taper it is identical.5 sets of collet chuck on the outer ring of movable expander 6, the upper end of collet chuck 5 is extended by taper compression face 51 and activity
The tapered squeezing face 61 of device 6 is in close contact, and the lower end of collet chuck 5 first is led by the second guiding conical surface 52 with determine core expander 4
It is in close contact to the conical surface 41.When movable expander 6 moves downward, collet chuck 5 is moved out along horizontal direction.
What collet chuck 5 cooperated with the first cylindrical surface 53 cooperated with bushing 9 to be processed and with mounting disc 7 to be processed
Second cylindrical surface 54.9 sets of bushing the first cylindrical surface 53 position and contacted with the first cylindrical surface 53,7 sets of mounting disc second
The position on cylindrical surface 54 is simultaneously contacted with the second cylindrical surface 54.
The supporting block for being used to support spacing pin 8 to be processed is fixed on ring flange 2.Hard alloy can be selected in supporting block
Block 10.
Ring flange 2 is fixed on pedestal 1, and pedestal 1 can be fixed with ring flange 2 by fasteners such as bolts.It is set on pedestal 1
It is equipped with the cylinder attachment base 3 for installing cylinder, by the mountable cylinder being connect with movable expander 6 of cylinder attachment base 3, from
And it can be moved up and down by cylinder drive activity expander 6.
The working principle that the utility model determines cored structure is as follows:
5 outer diameter of collet chuck respectively with 7 inner hole of 9 inner hole of bushing and mounting disc above.
Determine core expander 4 and be together by a threaded connection with ring flange 2 and be bolted on the tooling of pedestal 1 to fix
On plate.
5 sets of collet chuck on determining core expander 4, movable expander 6 passes through collet chuck 5 and determines the inner hole of core expander 4, then with
Cylinder axis connection.
Combination workpiece (mounting disc 7 and spacing pin 8 and bushing 9) combines rear enclosure on collet chuck 5, workpiece stress surface with
The hard alloy blocks 10 being embedded in ring flange 2 contact, and guarantee that base position is consistent.
Cylinder drive activity expander 6 moves downward when work, passes through the cooperation conical surface of movable expander 6 and collet chuck 5, cylinder
Folder 5 extends to the outside in parallel, two workpiece (mounting disc 7 and bushing 9) up and down is clamped, while also generating a lower pulling force, by two
A workpiece, which is securely seated between, to carry out welding or riveting processing on flange face, completes the process exhaust hood and unclamps, collet chuck elastic shrinkage,
Workpiece can be easily taken out, since collet chuck is upper and lower synchronous parallel spreading, is surface contact state with workpiece inner wall, is not commonly to rise
The line contact condition of core can control the concentricity of upper and lower two parts well, and the aid power of face contact is very big, can have
Effect resists the reaction force in process, guarantees processing stability and consistency.
