Description
Technical field
The utility model belongs to clay gun machine field, and in particular to a kind of fixed big gun mouth cap structure.
Background technique
Big gun mouth cap is mounted on clay gun clay extruded mechanism front end, and when stifled iron notch, big gun mouth cap directly pushes down tapping hole, and stemming is logical
It crosses big gun mouth cap inner hole and enters tapping hole channel, so that molten iron blocking, realizes stifled iron notch function.Big gun mouth cap is during blocking up to pass
Important, the stability of installation directly affects whether can smoothly block Tie Kou.
Since the big gun mouth front end of bolt-type big gun mouth cap structure is mounted on big gun mouth with reference to Fig. 1 and Fig. 2 for groove structure form
On big gun mouth cap can arbitrarily be rotated around axis, after rotating to certain angle, bolt is easy to fall off, directly results in big gun mouth cap from big gun
It falls off on mouth, to influence to use.
When pin hole is processed on big gun mouth cap, due to processing on arc surface, and hole direction is not orthogonal to cambered surface, in order to accurately add
Work pin hole just needs first to process a heavy platform, then the vertical pin hole processing in the heavy platform on arc surface, due to the thickness of big gun mouth cap
(d) intensity of big gun mouth cap itself is directly affected, the wall thickness (d1) of heavy platform is its weak link at two, when stifled iron notch, big gun mouth cap
Inner wall is divided by upward to impact force, which weakens wall thickness, be often broken at heavy platform, influences the normal of big gun mouth cap
It uses.
Utility model content
To solve the above problems, the utility model provides a kind of fixed big gun mouth cap structure, the connection of big gun mouth cap and big gun mouth
Take fixed, axial, radial all fixed, big gun mouth cap will not fall off when normal work, solve problem of the prior art.
In order to achieve the above objectives, the technical solution adopted in the utility model is: a kind of fixed big gun mouth cap structure, including big gun
Mouth cap and big gun mouth, big gun mouth cap sleeve are loaded on the end of big gun mouth, and big gun mouth offers blind hole, the circle of big gun mouth cap on the cylindrical surface of proximal end face
Taper pin-hole is offered on cylinder, the position of taper pin-hole is overlapped with the axis of blind hole, and taper pin is provided in taper pin-hole.
There are two taper pin-hole and blind hole are respectively provided with, the angle that the axis of two taper pin-holes is formed is 120 °.
Diameter of blind hole is greater than the diameter of taper pin-hole.
The length that taper pin protrudes into blind hole is less than the depth of blind hole.
It is interference fitted between taper pin and taper pin-hole.
Taper pin is consistent with the cone angle of taper pin-hole mating surface.
Big gun mouth cap and big gun mouth transition fit or clearance fit.
Blind hole inner bottom surface and smooth-sided transition.
The end of taper pin is provided with taper pin cap.
Compared with prior art, it is fixed at least to have the advantages that big gun mouth cap is taken with big gun mouth for the utility model
Connection, axially and radially all relatively fixed, big gun mouth cap will not fall off when normal work；Radially fixed pin shaft will not loosen, together
When it is also easy to disassemble, the circumferencial direction of big gun mouth without processing heavy platform, entire big gun mouth cap block up be hit power when, will not break
The problem of splitting.
Further, the axis of two taper pin-holes is in 120 °, and taper pin is not easy to fall in the big gun mouth course of work.
Further, the total length of taper pin is greater than the sum of taper pin-hole and blind hole depth, is easily installed and dismantles.
Further, the diameter that diameter of blind hole is greater than taper pin-hole can overcome the disadvantages that scale error when processing and assembly, more square
Being packed into taper pin axis just is justified in blind hole.
Further, blind hole internal end surface and smooth-sided transition, avoid occurring the problems in stress collection in blind hole.
Further, taper pin cap is arranged in the end of taper pin, and fixture easy to disassemble blocks taper pin cap and dismantled, increased simultaneously
Taper pin terminus area, impact force is excessive to taper pin pressure when reducing installation.

Specific embodiment
The utility model is described in detail with reference to the accompanying drawings and detailed description.
As shown in figure 3, a kind of fixed big gun mouth cap structure, including big gun mouth cap 1 and big gun mouth 2, big gun mouth cap 1 are set in big gun mouth 2
End, big gun mouth 2 by proximal end face cylindrical surface on offer blind hole, offer taper pin-hole, taper pin-hole on the cylindrical surface of big gun mouth cap 1
Position be overlapped with the axis of blind hole, taper pin 3 is provided in taper pin-hole；Diameter of blind hole is greater than the diameter of taper pin-hole；Taper pin 3 is stretched
The length for entering blind hole is less than the depth of blind hole；It is interference fitted between taper pin 3 and taper pin-hole；The cone of taper pin 3 and taper pin-hole mating surface
Angle is consistent；Big gun mouth cap 1 and 2 transition fit of big gun mouth or clearance fit；Blind hole internal end surface and smooth-sided transition；The end of taper pin 3
End is provided with taper pin cap.
As shown in figure 4, the angle that the axis of two taper pin-holes is formed is 120 ° there are two taper pin-hole and blind hole be respectively provided with.
Taper pin-hole at two is opened up on 1 periphery of big gun mouth cap, big gun mouth opens blind hole at two on 2 front end cylindrical surface, big gun mouth cap 1 is pacified
Loaded on 2 front end of big gun mouth, taper pin-hole is to director circle blind hole position and compresses, then by taper pin axis 3 be packed into big gun mouth cap 1 on two at taper pin
Hole, and load taper pin axis 3, by taper pin axis 3 by big gun mouth cap 1 and 2 axial restraint of big gun mouth.
Blind hole is cylinder, and the aperture of blind hole is greater than the aperture of taper pin-hole.
Big gun mouth cap 1 is sleeved on big gun mouth 2, and is compressed, the taper pin-hole on big gun mouth cap 1 is made to be directed at the blind hole on big gun mouth 2, dress
After tight taper pin axis 3 is installed with big gun mouth cap 1, preset clearance between 1 outside of taper pin axle cap and big gun mouth cap, taper pin axis 3 easy to disassemble, cone
Preset clearance, blind hole diameter are greater than taper pin shaft diameter between circle blind hole on pin shaft 3 and big gun mouth 2, can make up ruler when processing and assembly
Taper pin axis 3 is more easily packed into blind hole by very little error, and the bottom of taper pin axis 3 and the blind via bottom preset clearance on big gun mouth are
In order to which taper pin axis 3 and big gun mouth cap 1 are fitted closer, big gun mouth cap 1 is axially and radially all fixed, and big gun mouth cap 1, which will not generate, to be turned
Dynamic, taper pin axis 3 is not easily to fall off, and stability is good during the work time for entire big gun mouth cap 1, while also facilitating installation, disassembly, meets existing
Field normal demand.
Using taper pin-hole at two is opened on big gun mouth cap 1, no heavy platform weakens wall thickness, and blind hole at two is opened in corresponding position on big gun mouth 2, then
By taper pin axis connection big gun mouth cap 1 and big gun mouth 2, to realize that big gun mouth cap 1 and big gun mouth 2 are radial and axial relatively fixed.
