Description
Technical field
The utility model belongs to machinery positioning interconnection technique field, relates generally to a kind of locking circular cone latch structure.
Background technology
When four-point contact ball, intersection circular cone or crossing cylinder etc. structure are using overall lasso in current revolving support, lasso
It is upper to need the plug hole of a filling rolling element, and plug is connected by taper bolt and lasso, taper bolt is only relied on certainly
Body taper self-locking anti-loosing is fastened, and its locking fastening ability is poor, and when taper bolt is by impact shock load, the loosening of taper bolt is very
Happened occasionally to obscission；The attachment structure of existing taper bolt is as shown in Figure 1.
Utility model content
In order to solve the above technical problems, the purpose of this utility model is to propose a kind of locking circular cone pin joint structure.
The utility model adopts the following technical scheme that to complete its utility model task：
A kind of locking circular cone latch structure, described locking circular cone latch structure has locking taper bolt；Described locking circular cone
Sell for up big and down small circular cone stage body；The small end of the locking taper bolt has cross recess；The center of the cross recess has spiral shell
Pit；Described locking circular cone latch structure also includes the screw that the screwed hole having with locking taper bolt small end coordinates；Institute
The screw stated is up-small and down-big taper；Described screw cooperatively forms two ends with the screwed hole that locking taper bolt small end has
Tapered locking circular cone latch structure.
The utility model proposes a kind of locking circular cone pin joint structure, in circular cone latch structure small end thread mill drilling, and will
Taper pin small end is cut with cross recess, when being screwed into locking taper bolt small end screwed hole with conical external screw thread, can be by locking taper bolt
Small end spreading is tapered, is formed the big circular cone latch structure in a two ends, reaches locking purpose.
Brief description of the drawings
Fig. 1 general taper pin attachment structure schematic diagrams.
Fig. 2 is structural representation of the present utility model.
Fig. 3 is the structural representation of locking taper bolt in the utility model.
Fig. 4 is Fig. 3 side view.
Fig. 5 is the profile of locking taper bolt in the utility model.
Fig. 6 is the structural representation of screw in the utility model.
In figure；1st, taper bolt, 2, lasso, 3, plug, 4, screw, 5, locking taper bolt.
Embodiment
The utility model is illustrated with embodiment with reference to accompanying drawing：
As shown in Fig. 2 a kind of locking circular cone latch structure, described locking circular cone latch structure has locking taper bolt 5；As schemed
3rd, shown in Fig. 4, Fig. 5, described locking taper bolt 5 is up big and down small circular cone stage body；The small end of the locking taper bolt 5 has
Cross recess；The center of the cross recess has screwed hole；Described locking circular cone latch structure also includes small with locking taper bolt
The screw 4 that the had screwed hole in end coordinates；With reference to Fig. 6, described screw 4 is up-small and down-big taper；Described screw 4 with
The screwed hole that locking taper bolt small end has cooperatively forms the tapered locking circular cone latch structure in two ends；When with conical external screw thread
, can be tapered by the locking small end spreading of taper bolt 5 when screw 4 is screwed into locking 5 small end screwed hole of taper bolt, it is close to in lasso 2
On the reverse bellmouth of upper taper hole small end processing, the big circular cone latch structure in a two ends is formed（As shown in Figure 2）, reach anti-
Pinales.
