Abstract
The utility model belongs to the technical field of tool design and particularly relates to the improvement on a quick-detachment locating pressing pin belonging to the field of assembly design. The pressing pin comprises a locating pin (1), a shaft pin (2), a handle (3), a nut (4), a fixed-end lining (5), a movable-end lining (6), movable expansible linings (7) and movable conical sleeves (8), wherein the locating pin is sleeved with the nut (4). The locating pin (1) is connected with the handle (3) through the shaft pin (2). The locating pin (1) is sleeved with the movable-end lining (6), the movable expansible linings (7), the movable conical sleeves (8), the fixed-end lining (5) and the nut (4) in sequence from the handle end. Each movable conical sleeve (8) is matched with the corresponding movable expansible linings (7) through the conical surfaces at the two ends. Expansion gaps are formed in the movable expansible linings (7). When the quick-detachment locating pressing pin is used for locating and pressing a product with a hole, operation is easy and convenient, the structure is compact, and needed space is small.
Description
Technical field
The utility model belongs to Fixture Design technical field, particularly relate to trim designs field the improvement of quick-release positioning compression pin.
Background technique
In the time of Fixture Design, as in the time that assembly jig designs, often need to position compression by positioning hole to product, generally position and compress the mode adopting and have two kinds by positioning hole: the one, be used in conjunction with and position compression by ladder screw thread locating stud and nut; The 2nd, use separately cylinder latch location, the compressing member that re-uses other modes coordinates compression.Former structure is simple, and action required space is little, but can not position compression to blind hole, and screw thread rotation is also relatively time-consuming; The latter is simple to operate, but action required space is larger, and structure is not compact, and blind hole is also differed and located surely, need to determine according to actual conditions.
Summary of the invention
The object of the invention is:
The utility model provides a kind of quick-release positioning compression pin, simple to operation, compact structure, and requisite space is little, and can carry out effective positioning compression to the various types of holes on product.
Technological scheme of the present invention is:
A kind of quick-release positioning compression pin, comprise: locating stud 1, pivot pin 2, handle 3 and be enclosed within nut 4, fixed end lining 5, movable end lining 6, movable inflatable lining 7 and the removable conical cover 8 on locating stud, wherein, locating stud 1 is connected by pivot pin 2 with handle 3, locating stud 1 is from handle end, cover has movable end lining 6, movable inflatable lining 7, removable conical cover 8, fixed end lining 5 and nut 4 successively, removable conical cover 8 coordinates by the conical surface at two ends and the expansion bushing at two ends 7, on expansion bushing 7, has dilatation joint.
At least two inflatable linings 7 of activity and at least one removable conical cover 8 are spaced between fixed end lining 5 and movable end lining 6.
Advantage of the present invention is:
While adopting the utility model to position compression to product with holes, simple to operation, compact structure, requisite space is little, can carry out effective positioning compression to the hole on product, and the utility model with time be to position compression from the one-sided hole that puts in hole, so also can well locate blind hole.

Embodiment
Below the utility model is described in further details.Referring to Fig. 1, a kind of quick-release positioning compression pin, comprise: locating stud 1, pivot pin 2, handle 3 and be enclosed within nut 4, fixed end lining 5, movable end lining 6, movable inflatable lining 7 and the removable conical cover 8 on locating stud, wherein, locating stud 1 is connected by pivot pin 2 with handle 3, locating stud 1 is from handle end, cover has movable end lining 6, movable inflatable lining 7, removable conical cover 8, fixed end lining 5 and nut 4 successively, removable conical cover 8 coordinates by the conical surface at two ends and the expansion bushing at two ends 7, on expansion bushing 7, has dilatation joint.
At least two inflatable linings 7 of activity and at least one removable conical cover 8 are spaced between fixed end lining 5 and movable end lining 6.
When workpiece with hole is positioned to compression, first quick-release positioning compression pin is placed in to the hole that needs location, referring to Fig. 3, it is maximum with movable end lining 6 point of contact to the distance of the rotatingshaft of handle 3 that handle 3 is turned to handle 3, in the process increasing gradually in distance, the eccentric wheel part of handle 3 presses to fixed end lining 5 what continue by movable end lining 6, oppress to middle removable conical cover 8 under the pressure of two ends lining with the fixed end lining 5 inflatable lining 7 adjacent with movable end lining 6, under the effect of the conical surface matching at inflatable lining 7 and removable conical cover 8, between the two, pressure can be decomposed into axial pressure and radial pressure, because removable conical cover 8 is rigidity, hardly can be compressed, now 7 of inflatable linings can radially be expanded under radial pressure, cause Outer Diameter of lining to become large, the Spielpassung between quick-release positioning compression pin and product orientation hole can change interference fit into, reach the positioning compression fast and effectively to product by interference fit, as shown in Figure 5.
Working principle of the present utility model is: inflatable lining 7 can be to radial expansion under the pressure of two ends conical surface, thereby will between quick-release positioning compression pin and product orientation hole, change interference fit into by Spielpassung, reach the object of positioning compression product fast and effectively.
Claims (2)
1. a quick-release positioning compression pin, it is characterized in that, this compression pin comprises: locating stud (1), pivot pin (2), handle (3), be enclosed within the nut (4) on locating stud, fixed end lining (5), movable end lining (6), movable inflatable lining (7) and removable conical cover (8), wherein, locating stud (1) is connected by pivot pin (2) with handle (3), locating stud (1) is from handle end, cover has movable end lining (6) successively, movable inflatable lining (7), removable conical cover (8), fixed end lining (5) and nut (4), removable conical cover (8) coordinates by the conical surface at two ends and the expansion bushing at two ends (7), expansion bushing has dilatation joint on (7).
