Abstract
The utility model belongs to locating pin design field, in particular to locating pin auxiliary device, including locating pin, key seat, the coaxial core of locating pin is arranged at the column pipe intracavity of key seat, still includes the handle, being provided with the drive mechanism that can turn into the rotation of handle the axial displacement of locating pin between locating pin and the handle, during the operation, only needing the twist grip, through drive mechanism's conversion, the rotation of handle turns into the axial displacement of locating pin, and the locating pin only receives the push -and -pull effect of axial force and removes to no moment of flexure effect is on it, when also having avoided the locating pin to remove with the key seat on the pinhole between the friction, can keep the axial displacement of locating pin and then the positioning accuracy of assurance locating pin.
Description
Technical field
The utility model belongs to alignment pin design field, particularly a kind of alignment pin servicing unit.
Background technology
Alignment pin is widely used in mechanical field, can play the effect of location to part, is usually fixed in the key seat of hole class formation, promotes alignment pin afterwards, alignment pin is moved to specific station by servicing unit during alignment pin work.As alignment pin servicing unit old-fashioned in Fig. 1, alignment pin a does axial limiting motion in key seat b, the side connecting handle c of alignment pin a, handle c freely overhangs outside through the spacing hole d of the L shape that key seat b offers, one section of spacing hole d axial arranged, another section circumferentially, axial direction part moving handle c along spacing hole d drives alignment pin a to move axially, after arriving ad-hoc location, rotate in a circumferential direction the circumferential section of handle c to spacing hole d, the axially-movable of alignment pin a is just limited, the drawback of this kind of alignment pin servicing unit existence is, the power of running fix pin a acts on handle c, because handle c is the side being connected to alignment pin a, moment of flexure can be produced during artificial driving handle c, alignment pin a off-axis is produced to the hole wall with key seat b rub, time one is long, alignment pin a is caused to wear and tear, cause locate failure.
Utility model content
Content of the present utility model is to provide a kind of alignment pin servicing unit that can maintain positioning precision.
For realizing above object, the technical solution adopted in the utility model is: a kind of alignment pin servicing unit, comprise alignment pin, key seat, alignment pin coaxial core is arranged in the cylindricality tube chamber of key seat, also comprise handle, between described alignment pin and handle, be provided with the transmission mechanism moved axially that the rotation of handle can be converted into alignment pin.
Compared with prior art, there is following technique effect in the utility model: during operation, only need rotary handle, through the conversion of transmission mechanism, the rotation of handle is converted into moving axially of alignment pin, and alignment pin is only subject to the push-and-pull action of axial force and moves, there is no Moment on it, it also avoid the friction between pin-and-hole when alignment pin moves and on key seat, moving axially of alignment pin can be kept, and then ensure the positioning precision of alignment pin.

Detailed description of the invention
Below in conjunction with Fig. 1 to Fig. 5, the utility model is described in further detail.
A kind of alignment pin servicing unit, comprise alignment pin 10, key seat 20, alignment pin 10 coaxial core is arranged in the cylindricality tube chamber of key seat 20, also comprise handle 30, the transmission mechanism 40 moved axially that the rotation of handle 30 can be converted into alignment pin 10 is provided with between described alignment pin 10 and handle 30, when needing running fix pin 10, only need rotary handle 30, through the effect of transmission mechanism 40, the rotation of handle 30 can be converted into moving axially of alignment pin 10, when pin 10 to be positioned moves to specific station, positioning function can be realized, alignment pin 10 does not have the effect of moment of flexure in the process of movement, alignment pin 10 can keep moving axially always, thus positioning precision and operating efficiency can be maintained.
Described transmission mechanism 40 comprises movable push bar 41, and transmission mechanism 40 is connected by the rear end of movable push bar 41 with alignment pin 10, realizes being connected of transmission mechanism 40 and alignment pin 10.
Described transmission mechanism 40 comprises fixed block 42, the shaft of movable push bar 41 is through the through hole that fixed block 42 is offered, fixed block 42 is fixing on the table, described handle 30 is L shape pole, one end of pole freely overhangs, and the rear end of the other end and movable push bar 41 is hinged and connected, and the bending place of pole and one end of Rocker arm 43 are hinged and connected; the other end of Rocker arm 43 is hinged on the outside of fixed block 42, are arranged in parallel all between two between the jointed shaft of all hinged places.During use, first the free projecting end of operating personnel's gripping handle 30 rotates; Rocker arm 43 with the jointed shaft in fixed block 42 for rotating shaft rotates; handle 30 with the jointed shaft of bending place and movable push bar 41 rear end for rotating shaft rotates; because one end of handle 30 and the rear end of movable push bar 41 are hinged and connected; and movable push bar 41 is fixed block 42 limit and can only do axially-movable; so can axial sliding active push rod 41 when handle 30 rotates, and then drive moving axially of alignment pin 10.
Composition graphs 2-Fig. 4, described handle 30 comprises straight-bar 31, it is the dihedral first that splayed is arranged symmetrically with that one end of straight-bar 31 is extended with line centered by straight-bar 31, second pole 32, first, the end away from straight-bar 31 of the second pole 32 is hinged on the both sides of the rear end of movable push bar 41, first, the bending place respectively with the first of the second pole 32, one end of second Rocker arm 43 is hinged and connected, first, the other end of the second Rocker arm 43 is hinged on the both sides of fixed block 42, be arranged in parallel all between two between the jointed shaft of described all hinged places, first, second pole 32 is positioned at first, between second Rocker arm 43, by handle 30 and first, second Rocker arm 43 is designed to symmetrical structure, the power acted on when handle 30 is rotated on movable push bar 41 is also symmetrical, further ensure alignment pin 10 movement can not off-axis to, maintain the positioning precision of alignment pin 10.
Be threaded connection between described movable push bar 32 and alignment pin 10 and realize detachable cooperation, be convenient to the assembling of the two, dismounting.
