Abstract
The utility model discloses an integrated hole pressed positioning pin component, which aims at providing a positioning pin component which can be used for positioning and tightening. The positioning pin component comprises a positioning polished rod with a handle and a limit stop piece (7) is arranged in the middle part of the positioning polished rod. The positioning end of the limit stop piece is provided with screw threads connected with rectangular nuts. The rectangular nuts are assembled in a nut box (11) which limits the rotational freedom of the nuts. A positioning seat extending to two sides of the nut box (11) is provided with fastening thread holes connected with a fixed connector (3). Integrating positioning and fastening functions, the positioning pin component overcomes the defect of single purpose of a positioning system with positioning pin in the prior art so as to fully develop the functions of the positioning pin in the prior art. The integrated hole pressed positioning pin component not only increases the operable space of tooling and simplifies the structure of tooling, but also reduces the quantity of operating personnel and improves working efficiency, with use rate which can be improved by more than one time.
Description
Technical field
The utility model relates to that a kind of to be mainly used on the assembly tooling anchor clamps hole that the location compresses part simultaneously be alignment pin.
Background technology
The hole that is used for locating element in the prior art assembly tooling in a large number is a locator, is to lock with the alignment pin of many participations shown in Figure 2 location and a plurality of screw-nut to realize.This alignment pin is a kind of polished rod class locator with handle.During use, polished rod inserts in the hole in piece part of corresponding desire location, with the part location, also will part be compressed also fastening with the mounting screw nut simultaneously.In the use, usually need two operating personnel, operating personnel insert the locating hole of detachable part or adjustable locator with alignment pin, another operating personnel are mounting screw nut and tightening then, promptly needs two work steps just can finish the location of locating hole and being fixed part.
Summary of the invention
The purpose of this utility model is many at prior art alignment pin locating element quantity, and the weak point that operating efficiency is low provides a kind of pin assembly that can locate and can be fastening.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of integral type hole system compresses pin assembly, comprise, a location polished rod that has handle, it is characterized in that, polished rod middle part, location is provided with a positive stop, its termination, location is shaped on the screw thread that connects the rectangle nut, the length of the location polished rod on the alignment pin is slightly less than the thickness sum of detachable locator and fixed connector, the end of thread at described alignment pin is equipped with rectangle nut and the rectangle nut box that limits its rotational freedom, and this nut box is shaped on the positioning seat of both sides extension and is connected and fixed the fastening screw pit that connects device.
Beneficial effect than prior art of the present utility model is, the utility model is integrated in the trip bolt of fastenings on the alignment pin, to locate, fastening function is integrated in one, overcome the single deficiency of prior art alignment pin navigation system purposes, fully expanded the function of prior art alignment pin.But so not only can increase the operating space of frock, simplify tool structure, and reduce operating personnel's quantity, improve work efficiency.The location, fastening two procedures only operating personnel just can disposablely be finished, and uses speed to be enhanced about more than once, and has both reduced manufacturing cost, has improved production efficiency again and has shortened the production cycle.The assembling of one sortie aircraft just can be saved thousands of man-hours.
Description of drawings
The utility model integral type hole system compresses the organigram of pin assembly band part section on Fig. 1.
Fig. 2 is that the prior art hole is the composition schematic diagram of locator.
Among the figure: 1. alignment pin, 2. detachable locator, 3. fixed connector, 6. location polished rod, 7. positive stop, 8. screw thread, 9. conical head, 10. rectangle nut, 11. nut boxes, 12. gaps, 13. positioning seats.
The specific embodiment
In Fig. 1, there is not mutual interference for making things convenient for hand disassembly and a plurality of threaded to work together in narrow and small zone, on the end of the location polished rod 6 of middle alignment pin 1, have the movable handle of tightening usually.Be the accuracy and the reliability of convenient location, be shaped on a positive stop 7 at polished rod 6 middle parts, location.Being shaped on convenient introducing fast hole in the termination, location of location polished rod 6 is the conical head 9 of locating hole and the screw thread 8 that is connected the rectangle nut.The rectangle nut can be a square nut 10.Square nut 10 is assemblied in and can limits its rotational freedom in nut box 11.Square nut 10 is placed in the cavity of nut box 11.Because square nut 10 appearance and sizes are slightly less than nut box 11 inner cavity sizes, square nut 10 produces gap 12 with nut box 11 inner chamber walls.This gap 12 only can make square nut 10 that certain one-movement-freedom-degree is arranged in nut box 11, and can not rotate along the screwed hole axis of square nut 10.When off working state, since the existence in this gap, the locating hole disalignment on square nut 10 screwed hole axis and detachable locator 2 and the fixed connector 3., on the positioning seat 13 of both sides extension, be shaped on and be connected and fixed the fastening screw pit that connects device 3 at nut box 11.Nut box 11 with square nut 10 connects by screw, and is fixed on the fixed connector 3.Alignment pin 1, rectangle nut 10, nut box 11 are organic wholes that cooperatively interact.
Location polished rod 6 diameters on the alignment pin 1 are consistent with the locating hole diameter on detachable locator 2 and the fixed connector 3.The locating hole that location polished rod 6 passes on detachable locator 2 and the fixed connector 3 has limited 2 five frees degree of detachable locator, makes it only have unique free degree of location polished rod 6 axial directions not controlled in the space.The length of the location polished rod 6 on the alignment pin 1 is slightly less than the thickness sum of detachable locator 2 and fixed connector 3.When duty, rectangle nut 10 end faces and positive stop 7 end faces compress detachable locator 2 and fixed connector 3 respectively, rather than rectangle nut 10 end faces are pressed on the front end face of location polished rod 6, make tightening force limit the free degree of detachable locator 2 at location polished rod 6 axial directions.Detachable locator 2 is meant under work condition state, is connected with fixed connector with the attachment screw nut by alignment pin 1, has limited six-freedom degree, and unique position and state are only arranged in the space, removable locator under non-work condition state.Fixed connector 3 has been limited six-freedom degree in the space, and the connector of unique position and state is only arranged in the space, is shaped on the hole that is connected with detachable locator 2 on it to be.
During duty, location polished rod 6 front ends that play the alignment pin effect pass the locating hole on detachable or adjustable locator 2 and the fixed connector 3.The screw thread 8 that plays location polished rod 6 terminations of positioning action cooperates with square nut 10, rotation by nut box 11 restriction square nuts 10, location polished rod 6 can be rotated in the screwed hole of its square nut 10,10 on square nut can not servo-actuated, so that positive stop 7 and square nut 10 are tightly pushed down detachable or adjustable locator 2 and are fixed connector 3, play effect, location polished rod 6.
