In same horizontal line.
The working principle and beneficial effect of this base case are: mostly using cantilever beam structure greatly in the prior art to install
Lead screw mould group, and two groups of positioning units are provided in this programme, and two the first locating pieces in two groups of positioning units are in
Same level, two the second locating pieces are also in same level, when the mounting base of lead screw mould group is mounted on two positioning units
After upper, two positioning units can play the role of support to mounting base, so screw rod is not after lead screw mould group installs
It can deviate radially, also with regard to the adjusting without carrying out concentricity to it.
Further, the bed piece is equipped with the inclined surface for installing lead screw mould group, and the positioning unit setting exists
On inclined surface.Using this programme, when lead screw mould group is mounted on positioning unit, the mounting base of lead screw mould group can be directly born against
It on baffle and does not fall off, is easily installed and positions.
Further, horizontal on the bed piece to be equipped with the first groove body and the second groove body, first groove body and second
It is opened up on the upside of the inner wall of groove body there are two mounting groove, is equipped with spring on the upside of the inner wall of the mounting groove, the first spring is close to the
One end of one groove body is connected with push plate；The bottom of first locating piece and the second locating piece is equipped with mounting blocks, the installation
The width of block is greater than or equal to mounting groove, and mounting blocks can be threadedly coupled with push plate.Since the effect of positioning unit is to give lead screw mould
Group carry out origin reference location, guarantee the precision of its concentricity, thus this programme have to the position precision of positioning unit itself it is high
It is required that if only only the first locating piece and the second locating piece are installed according to common installation method, then not can guarantee two
Person is in same horizontal line.In the present solution, the first groove body and the second groove body are processed by the way of knife processing,
Its precision is able to satisfy requirement.Two mounting grooves are provided on the upside of the inner wall of the first groove body, the second groove body, and since bed piece inclines
Tiltedly setting, so mounting blocks can slide into the first groove body, the second slot automatically after mounting blocks are placed into the first groove body, the second groove body
On the downside of the inner wall of body, it is now placed in intracorporal two mounting blocks of the first slot and keeps in the same horizontal line.Meanwhile it being set in this programme
There are spring and push plate, mounting blocks can be pushed against on the downside of the inner wall of the first groove body, the second groove body by push plate under the action of the spring,
Mounting blocks are avoided to shake.
Further, the arcwall face being recessed inwardly is equipped with towards the side of the first locating piece on the baffle.Using this programme,
The mounting blocks of lead screw mould group easy to support.
Further, the arcwall face is embedded in equipped with magnet.When the mounting blocks of lead screw mould group lean against on arcwall face, magnet
It can have been attracted, it is prevented to be subjected to displacement.
