Description
Technical field
The utility model belongs to field of mechanical technique, particularly a kind of locating shaft.
Background technology
Locating shaft is orientation tool conventional in machining, apply widely in machining, common locating shaft is generally adopt to plug mode and be installed on part of appliance, be fastened on part of appliance by securing members such as corresponding nut or clips again, this not only installs trouble, and installer easily forgets to locating shaft mounting nuts or clip in heavy installation exercise, thus there is potential safety hazard, easily security incident occurs.
Summary of the invention
The purpose of this utility model there are the problems referred to above for existing technology, proposes the locating shaft that a kind of structure is simple, practical.
The purpose of this utility model realizes by following technical proposal: a kind of locating shaft, comprise the head and shank that are connected as a single entity, the external diameter of head is greater than the external diameter of shank, it is characterized in that, on the lateral wall that shank two is relative, circumferentially direction all offers symmetrically arranged deep-slotted chip breaker, radially through hole is offered and through hole two ends are connected with corresponding deep-slotted chip breaker respectively at shank, latch segment is equipped with in two deep-slotted chip breakers, latch segment is made up of the tight lock part of the connecting portion be connected as a single entity and curved shape, the connecting portion of two latch segments to be all inserted in through hole and to be connected by spring between the inner of two connecting portions, a tight lock part part also and between deep-slotted chip breaker bottom land has gap in deep-slotted chip breaker, tight lock part another part stretches out deep-slotted chip breaker and have approaching face on the tight lock part sidewall of this part, the complete retraction of tight lock part can be made in deep-slotted chip breaker when tight lock part is stressed.
Compared with prior art, the utility model by offering deep-slotted chip breaker on shank, and correspondingly in deep-slotted chip breaker be configured with latch segment, when locating shaft is being inserted in part of appliance axis hole process, latch segment is squeezed and moves inward until complete retraction is in deep-slotted chip breaker, now locating shaft can pass through axis hole smoothly, at latch segment by after axis hole, under the effect of spring force, latch segment returns to initial position and is resisted against on box end, thus coordinate together with head and make locating shaft firm can be inserted in pin-and-hole, without the need to by other fastenings, locating shaft only need be inserted in pin-and-hole and this locating shaft and part of appliance can be made to be fastenedly connected by assembler, easy to use, assembling is simple.

In figure, 1, head; 2, shank; 21, deep-slotted chip breaker; 22, through hole; 3, latch segment; 31, connecting portion; 32, tight lock part; 33, approaching face; 4, spring.
Detailed description of the invention
Be below specific embodiment of the utility model and by reference to the accompanying drawings, the technical solution of the utility model is further described, but the utility model be not limited to these embodiments.
As depicted in figs. 1 and 2, this locating shaft comprises the head 1 and shank 2 that are connected as a single entity, the external diameter of head 1 is greater than the external diameter of shank 2, on the lateral wall that shank 2 liang is relative, circumferentially direction all offers symmetrically arranged deep-slotted chip breaker 21, through hole 22 is radially offered and through hole 22 two ends are connected with corresponding deep-slotted chip breaker 21 respectively at shank 2, latch segment 3 is equipped with in two deep-slotted chip breakers 21, latch segment 3 is made up of the tight lock part 32 of the connecting portion 31 be connected as a single entity and curved shape, the connecting portion 31 of two latch segments 3 to be all inserted in through hole 22 and to be connected by spring 4 between the inner of two connecting portions 31, tight lock part 32 part also and between deep-slotted chip breaker 21 bottom land has gap in deep-slotted chip breaker 21, tight lock part 32 another part stretches out deep-slotted chip breaker 21 and have approaching face 33 on tight lock part 32 sidewall of this part, the complete retraction of tight lock part 32 can be made in deep-slotted chip breaker 21 when tight lock part 32 is stressed.
By offering deep-slotted chip breaker 21 on shank 2, and correspondingly in deep-slotted chip breaker 21 be configured with latch segment 3, when locating shaft is being inserted in part of appliance axis hole process, latch segment 3 is squeezed and moves inward until complete retraction is in deep-slotted chip breaker 21, now locating shaft can pass through axis hole smoothly, at latch segment 3 by after axis hole, under the effect of spring 4 elastic force, latch segment 3 returns to initial position and is resisted against on box end, thus coordinate together with head 1 and make locating shaft firm can be inserted in pin-and-hole, without the need to by other fastenings, locating shaft only need be inserted in pin-and-hole and this locating shaft and part of appliance can be made to be fastenedly connected by assembler, easy to use, assembling is simple.
The curved shape of tight lock part 32 simultaneously, when one of them latch segment 3 radially outward moves, another latch segment 3 radially-inwardly can move and be resisted against on deep-slotted chip breaker 21, puts structure and two tight lock parts 32 are restricted mutually, ensure that latch segment 3 can not fall down from locating shaft, good stability.
Specific embodiment described herein is only to the explanation for example of the utility model spirit.The utility model person of ordinary skill in the field can make various amendment or supplements or adopt similar mode to substitute to described specific embodiment, but can't depart from spirit of the present utility model or surmount the scope that appended claims defines.
