Description
Technical field
The present invention relates to a kind of axial pin conveying mechanism, particularly a kind of axial pin conveying mechanism under the liquid nitrogen cryogenics environment.
Background technology
When pivot pin and hole assembling, need tighter interference fit under a lot of situation.Often adopt and earlier pivot pin is put into the freezing contraction of liquid nitrogen, assemble again.This work is now accomplished by manual work mostly.Here relate to a kind of can be under the liquid nitrogen cryogenics environment conveying mechanism of smooth operation, it is fully freezing automatically pivot pin to be put into liquid nitrogen, and proposes the liquid nitrogen bucket in freezing back.
Summary of the invention
The purpose of this invention is to provide a kind of axial pin conveying mechanism under liquid nitrogen cryogenics, it can be automatically that pivot pin is put into liquid nitrogen is fully freezing and pivot pin proposed, can be under the liquid nitrogen cryogenics environment the ability smooth operation.
For achieving the above object, the present invention adopts following proposal:
A kind of axial pin conveying mechanism under the liquid nitrogen cryogenics environment; The liquid nitrogen lid that comprises liquid nitrogen container and coupling thereof; It is characterized in that having a pivot pin storage rotation mechanism, a pivot pin to transfer to mechanism and a pivot pin to propose mechanism all is installed in the liquid nitrogen container; The corrosion-resistant steel optical axis that said pivot pin storage rotation mechanism has a central vertical stretches out and through the direct servomotor of transmission device from liquid nitrogen cover centre hole; Said pivot pin extraction mechanism is connected with the bottom of said corrosion-resistant steel optical axis, and said pivot pin proposes mechanism has the pull bar of joining with the feather key cunning to stretch out and is connected with servo cylinder from liquid nitrogen cover rectangular slot, and liquid nitrogen container has covered pivot pin and imported and overlap; Pivot pin imports cover through the pivot pin that is installed in liquid nitrogen container and covers and falls into pivot pin storage rotation mechanism, and pivot pin storage rotation mechanism can store a plurality of pivot pins simultaneously and pivot pin delivered to pivot pin after freezing and transfer to mechanism; Pivot pin transfers to mechanism to carry the bucket place with what pivot pin was allocated to that pivot pin proposes mechanism, proposes mechanism by pivot pin it is proposed liquid nitrogen container.
The physical construction of above-mentioned pivot pin storage rotation mechanism is: have two back plates and liquid nitrogen cover to be connected through screw, 8 joint sales at reduced prices are connected through screw and two sides.Put a storage pin rotating disk between per two joint sales at reduced prices, totally 8 storage pin rotating disks, the corrosion-resistant steel optical axis is connected through screw and these 8 storage pin rotating disks, and sky overlaps between corrosion-resistant steel optical axis and the joint sale at reduced prices.Servomotor MSMD 012 P1U is through planetary reduction gear, and the Zero clearance cross coupler is connected with the corrosion-resistant steel optical axis, and power is provided.Totally 6 kinds connect sale at reduced prices, and each joint sale at reduced prices respectively has a joint discharge hole, and just the hole site is different, is 60 ° of six five equilibrium, is installed on back plate successively from top to bottom.Servomotor drives corrosion-resistant steel optical axis and 8 storage pin rotating disks, per 60 ° of stepper drive.Pivot pin imports cover through the pivot pin that is installed in liquid nitrogen container and covers and falls into the joint sale at reduced prices, and in one step of motor revolution, the sale at reduced prices of one deck joint falls into a pivot pin, and storage pin rotating disk transfers to a pivot pin to fall into down one deck simultaneously.Can avoid the damage that bumps between the pivot pin like this, and enough freezing times are arranged.The joint discharge hole of preceding 4 layers of joint sale at reduced prices is the conter clockwise discharging, and servomotor cw stepping rotation is so the sale at reduced prices of one deck joint can be put 5 pivot pins simultaneously.The joint discharge hole of the 4 layers of joint sale at reduced prices in back is the cw discharging, so the sale at reduced prices of one deck joint can only store 1 pivot pin.This is in order rationally to arrange freezing time and quantity that simultaneously can freezing pivot pin.
Above-mentioned pivot pin transfers to the physical construction of mechanism to be: have one to go up positioning disk and a following positioning disk, following positioning disk and two sides are connected through screw.The corrosion-resistant steel optical axis is connected through screw and dial, and overlaps with positioning disk off-centre is empty up and down.Because up and down positioning disk is eccentric with the hole of the empty cover of corrosion-resistant steel optical axis, and positioning disk has guide groove up and down, can arrive the proposition position so that dial is transferred to the pivot pin peace when rotating according to guide groove.
The physical construction that above-mentioned pivot pin proposes mechanism is: one on pull bar is connected with rack-mount servo cylinder QGW N232X400SDD, by servo cylinder power is provided, and the other end is connected with carrying struggling against.Carry the bucket position be in transfer to mechanism to transfer to pivot pin the position in order to catch pivot pin.Feather key is installed on the back plate through screw.To carry bucket through servo cylinder mentions along feather key.
The smooth operation scheme is under the above-mentioned assurance low temperature environment: the material choosing of whole conveying mechanism then will meet the liquid nitrogen cryogenics environment requirement; The part that contacts with pivot pin---joint sale at reduced prices, storage pin rotating disk, positioning disk and dial material all adopt polychlorotrifluoroethylene up and down; Motor; Cylinder is installed in outside the liquid nitrogen, avoids in liquid nitrogen, using spring, the uncertain part of low-temperature propertiess such as bearing.
