Specific embodiment
The present invention will be further described with reference to the embodiment in attached drawing below：
As shown in Figure 1, the invention mainly comprises baffle 1, bearing block 2, bearing 3, positioning pin 4, supporting support 8 and two rollings
Wheel 9.
Bearing 3 is equipped in bearing block 2, positioning pin 4 is rotatablely connected in bearing 3.2 rear end of bearing block is connected by screw 5 and kept off
Plate 1 is equipped with gap so that baffle 1 can be slided up and down along screw 5 between baffle 1 and screw 5.The bearing 3 and positioning pin
It is interference fit connection between 4.
Pocketed springs 7 on screw 5, spring 7 are located between 1 rear end face of 5 head of screw and baffle.5 head of screw and
Gasket 6 is equipped between 7 rear end of spring.
As shown in Fig. 2 ~ 3,4 front end of positioning pin is equipped with supporting support 8, and 8 upper end of supporting support is equipped with the supporting surface of V-arrangement.
When carrying out plunger assembly closing in, on the supporting surface for the V-arrangement that plunger 10 is placed on to supporting support 8, the rear end face of plunger 10 passes through
Positioning pin 4 is held out against.
8 front end of supporting support is set there are two idler wheel 9, and two idler wheels 9 are symmetrical arranged at left and right sides of 8 front end of supporting support.
When carrying out plunger assembly closing in, 11 bulb of piston shoes is put into 10 ball-and-socket of plunger, plunger 10 is clamped by two idler wheels 9, is passed through
Two idler wheels 9 drive plunger 10 to rotate on one side, on one side the bulb intracavitary direction feeding of the plunger 10 in supporting support 8, so as to
Realize the closing in work of plunger assembly.
The present invention operation principle be：Positioning pin is connected by bearing block and bearing interference fit.Baffle is fixed on rolled thread
On machine base, bearing block is connect by two screws and two springs with baffle, is to loosen between baffle and screw；It is fixed simultaneously
Mode is gap-matched with bearing block at the maximum outer circle of position pin, therefore is both loosening.Therefore pass through such connection mode, positioning
Pin can up and down direction it is rotatable without constraint.When being closed up, plunger and piston shoes are placed on support by Fig. 2 directions
On stent, wherein piston shoes bulb will be put into plunger ball-and-socket.By the self-centering action of the supporting surface of the V-arrangement of supporting support and
The rotatable function of positioning pin, makes plunger base that can be fitted closely with positioning pin, is fixed on a position.When starting idler wheel,
The mode of action of two idler wheels is：One side idler wheel is fixed, is rotated；Another side idler wheel is inwardly fed, and is rotated.Together
When ensure both sides idler wheel direction of rotation it is identical.Idler wheel will inwardly be compressed in rotation and inwardly feeding at plunger outer circle, reach column
The effect that piston shoes close up is filled in, while plunger can be driven to be rotated.Since plunger bottom surface is close on positioning pin, thus plunger into
Positioning pin is driven to be rotated while row rotation, prevent stuck phenomenon.Simultaneously by the active force of spring, make positioning pin
During entire close up the stability of closing in post gap is ensure that with plunger sticking jail always.
