Abstract
The utility model belongs to the technical field of the fastener is used in the mechanical engineering assembly, especially relate to an elasticity pin of adjustable length. By outer thread sleeve, the pin, the spring axle, the pull rod axle, limiting clamping plate, manual pull ring, compression spring and lock nut constitute, the serve as reasons shoulder hole of big footpath hole and path punch combination one -tenth of outer thread sleeve's hole, the junction in big footpath hole and path hole is the plane step, pin surface and outer thread sleeve's big footpath hole sliding connection, the surface of spring axle and outer thread sleeve's path hole sliding connection, compression spring lies in between the terminal surface and plane step of pin, outer thread sleeve's path nose end is equipped with vertical slot, this vertical slot is pegged graft with limiting clamping plate mutually. The utility model discloses can adjust the length of pinning according to the hole of connecting piece is long, the commonality is stronger, and positioning accuracy is higher relatively, and it is convenient, swift to dismantle moreover.
Description
Technical field
The utility model belongs to the technical field of mechanical engineering assembling fastening piece, particularly relates to a kind of length-adjustable Elastip pin.
Background technique
Normal pin connection is mainly used in assembling and positioning, also can be used as union piece, can also cut off element as the overload in safety installations.But most of pin syndeton length is fixed, and machining accuracy and positioning precision are also different.Although normal pin also can repeatedly be dismantled, if pin directly connects two connected compcnent, under the occasion having shock and vibration, pin hole is easy to wearing and tearing.May wear to a certain degree, during owing to can not ensure the positioning precision required, connected compcnent also must be changed.Especially, when there being a component costs higher in two connected pieces, selecting during pin and just needing to consider this connected piece of protection.Such as: certain factory's magnetic dewater cone driving mechanism is spline fitted, wherein inner spline sleeve bottom needs to connect a pull bar by pin.If select common pin to connect herein, under shock and vibration, the pin hole on sleeve and the pin hole on pull bar are easy to wearing and tearing, when wearing and tearing acquire a certain degree can not meet need of work time, sleeve and pull bar just need all to change.But inner spline sleeve processing difficulties, cost is higher, so when selecting pin, should lay special stress on protecting inner spline sleeve.
Summary of the invention
The purpose of this utility model is to provide that both positioning precisioies are higher, adjustable length, same specification versatility are comparatively strong and convenient disassembly, and is applicable to the length-adjustable Elastip pin of one of the assembling of all kinds of mechanical device and location.
The purpose of this utility model is realized by following technical proposals:
The length-adjustable Elastip pin of one of the present utility model, by external thread sleeve, the pin that is slidably connected of external thread sleeve endoporus therewith, the spring shaft that is fixedly connected with of pin therewith, the pull rod shaft that is connected of spring shaft therewith, the spacing clamp that is connected of pull rod shaft therewith, the manual draw ring that is connected of spacing clamp therewith, be enclosed within Compress Spring on described spring shaft and the locking nut be threaded with described external thread sleeve and setscrew nut formed, the endoporus of described external thread sleeve is the shoulder hole be made up of hole, large footpath and diameter holes, the joint of described hole, large footpath and diameter holes is land plateau, the hole, large footpath of described pin outer surface and described external thread sleeve is slidably connected, the outer surface of described spring shaft and the diameter holes of described external thread sleeve are slidably connected, described Compress Spring is between the end face and described land plateau of described pin, the path nose end of described external thread sleeve is provided with longitudinal socket, this longitudinal socket and described spacing clamp plug.
The longitudinal length of described spacing clamp is equal with the longitudinal socket length on described external thread sleeve, and the horizontal width of described spacing clamp is greater than the outer surface diameter 5mm-10mm of described external thread sleeve.
The utility model has the advantages that:
The utility model can regulate pin length according to the hole of link is long, and versatility is comparatively strong, and positioning precision is relatively high, and convenient disassembly, quick.
Accompanying drawing explanation
Fig. 1 is off working state structural representation of the present utility model.
Fig. 2 is working state structure schematic diagram of the present utility model.
Embodiment
Embodiment of the present utility model is further illustrated below in conjunction with accompanying drawing.
As Fig. 1, shown in 2, the length-adjustable Elastip pin of one of the present utility model, by external thread sleeve 4, the pin 9 that is slidably connected of external thread sleeve 4 endoporus therewith, the spring shaft 5 that is fixedly connected with of pin 9 therewith, the pull rod shaft 3 that is connected of spring shaft 5 therewith, the spacing clamp 2 that is connected of pull rod shaft 3 therewith, the manual draw ring 1 that is connected of spacing clamp 2 therewith, be enclosed within Compress Spring 7 on described spring shaft 5 and the locking nut 8 be threaded with described external thread sleeve and setscrew nut 11 formed, the endoporus of described external thread sleeve 4 is the shoulder hole be made up of hole, large footpath and diameter holes, the joint of described hole, large footpath and diameter holes is land plateau 6, the hole, large footpath of described pin outer surface and described external thread sleeve is slidably connected, the outer surface of described spring shaft and the diameter holes of described external thread sleeve are slidably connected, described Compress Spring 7 is between the end face and described land plateau 6 of described pin 9, the path nose end of described external thread sleeve is provided with longitudinal socket 10, this longitudinal socket 10 plugs with described spacing clamp 2.
The longitudinal length of described spacing clamp is equal with the longitudinal socket length on described external thread sleeve, and the horizontal width of described spacing clamp is greater than the outer surface diameter 5mm-10mm of described external thread sleeve.
Number in the figure 13, 12 is two to be connected, manual draw ring 1 is needed to pull out before using, spacing clamp 2 is stuck on the end face of external thread sleeve 4 by the axial force of Compress Spring 7, during use, first external thread sleeve 4 is threaded with link 12, be tightened with locking nut 8 after adjusting position, then by the longitudinal socket 10 that inserts after spacing clamp 2 90-degree rotation on external thread sleeve 4, the longitudinal length value of this longitudinal socket 10 is maximum functional strokes of pin 9, if need the maximum functional stroke distances being less than pin 9, the position of adjustable setscrew nut 11, then slowly decontrol, Compress Spring 7 is released, pin 9 is driven to insert in the hole to be installed of link 13, last spacing clamp 2 is stuck on longitudinal socket 10 bottom or is stuck on setscrew nut 11.
When needs dismounting pin, only need manually draw ring 1 to pull out spacing clamp 2, be again stuck on the end face of external thread sleeve 4 after rotary stopper clamp 90 degree.
