Description

A kind of simple and easy spiral pin removal
Technical field
The utility model relates to a kind of pin removal.
Background technology
On technological equipments such as all kinds of anchor clamps, mould or equipment, in order to guarantee the positioning accuracy between zero parts, need to adopt alignment pin to position, but be mounted in the blind hole at some spots localization pin, alignment pin need be taken out when considering maintenance, the general internal thread alignment pin that adopts utilizes internal thread that alignment pin is taken out.Present stage mainly adopts the ram type pin removal that the internal thread alignment pin is taken out, this kind mode is knocked by the artificial application of force and is operated, use cumbersome, labour intensity is big, very easily pound in one's hands, have certain potential safety hazard, and its impact is easy to damage alignment pin, finally causes alignment pin to take out.
Summary of the invention
The purpose of this utility model is to provide a kind of efficient height of pulling pin, simple and easy spiral pin removal that security is good.
To achieve these goals, the technical solution of the utility model is: a kind of simple and easy spiral pin removal, it is characterized in that it comprises handle nut 1, feather key 3, sleeve 4, pull bar 5, screw rod 6, internal thread in the inner bolt hole of the external screw thread of the bottom of screw rod 6 and alignment pin to be pulled out 7 matches, when pulling pin, the bottom of screw rod 6 screws in the internal thread hole of alignment pin 7; The bottom thread connection of the upper end of screw rod 6 and pull bar 5; Sleeve 4 is enclosed within on the pull bar 5, and pull bar 5 has gathering sill vertically, and sleeve 4 is provided with the guiding keyhole along the vertical axis direction, and an end of feather key 3 is positioned at the gathering sill of pull bar 5, and the other end of feather key 3 is positioned at the guiding keyhole of sleeve 4; Constitute screw pair in the internal thread hole of the upper end screw-in handle nut 1 of pull bar 5, handle nut 1 is positioned at the top of sleeve 4.
Be with packing ring 2 on the described pull bar 5, packing ring 2 is between handle nut 1 and sleeve 4.
The utility model has been abandoned traditional ram type principle of pulling pin, increase the mode of feather key by nut (handle nut 1), screw rod, rotatablely moving of nut changed into the rectilinear motion of screw rod, apply less pulling force and can extract alignment pin, effectively improve the efficient of pulling pin, simple to operate, it is laborsaving to pull pin, and has solved the problem of security hidden danger; Simultaneously, the utility model only need be changed pull bar and screw rod (zinc-plated screw rod), can realize the taking-up function of the internal thread alignment pin of different size specification.Pull bar can all be designed to the interface that is connected with screw rod at two ends, reduces variety classification.
