Description
Technical field
The utility model relates to machine tooling technical fields, and in particular to a kind of screw mandrel support seat mechanism.
Background technique
With the fast development of numerically-controlled machine tool, demand of the market to large-size numerical control machine is continuously increased, 5 meters or more of numerical control
Lathe emerges one after another, and traditional machine tool pedestal is bigger, and drive lead screw is longer, and being affected by gravity influences with screw rod processing factors, and screw rod is got over
Long running precision is more difficult to guarantee, to affect the machining accuracy of whole numerically-controlled machine tool.In consideration of it, it is necessary to study a kind of screw rods
Support seat mechanism.
Summary of the invention
To solve the deficiencies in the prior art, the purpose of this utility model is to provide one kind to run smoothly, easy for installation, can
The screw mandrel support seat mechanism high by property.
In order to achieve the above objectives, the utility model adopts the following technical solutions:
A kind of screw mandrel support seat mechanism, including screw rod lip block, the bottom end of screw rod lip block are provided with sliding block combination,
Top middle portion is provided with screw mandrel support seat, and top two sides are provided with anticollision seat, and the front-end and back-end of anticollision seat are provided with anti-
Collision block, the outside vertical of anticollision seat are provided with connecting rod fixed block, and via hole is provided in the middle part of connecting rod fixed block, is fixed in via hole
There is connecting rod.
Preferably, it is connected between aforementioned screw rod lip block and sliding block combination by bolt.
More preferably, it is provided with semi-circular recesses at the top of aforementioned screw mandrel support seat, is provided with screw rod in groove.
It is highly preferred that aforementioned screw mandrel support seat is made of POM material, lead between screw mandrel support seat and screw rod lip block
Bolt is crossed to be connected.
It is further preferred that aforementioned anticollison block is made of excellent power glue material, cylindrical end face is equipped with counter sink, runs to
Extreme position contacts with equipment and plays buffer function.
The screw mandrel support seat mechanism for having the beneficial effect that the utility model of the utility model is transported using ball screw itself
Row drives the operation of screw mandrel support seat mechanism, and screw mandrel support seat uses POM material, with that coefficient of friction is small, wearability is good is excellent
Point, screw mandrel support seat mechanism are installed to linear slider combination above, increase the stability and fluency of overall operation, are longer
Lead screw increases the fulcrum of respective numbers, to reduce the influence compared with long screw because of gravity sag to numerically-controlled machine tool running precision.

POM material is made, and is connected between screw mandrel support seat 2 and screw rod lip block 1 by bolt.
Anticollison block 5 is made of excellent power glue material, and cylindrical end face is equipped with counter sink, is run to extreme position and is connect with equipment
Buffer function is played in touching.
In Fig. 3,2 mechanism of screw mandrel support seat can be driven by ball-screw 8 while operation is to realize multi-point support, two groups
2 mechanism of screw mandrel support seat can be achieved to support the two o'clock of lead screw 7 by the connection of connecting rod 6.
2 mechanism of screw mandrel support seat of the utility model drives 2 mechanism of screw mandrel support seat to transport using ball screw operation itself
Row, and screw mandrel support seat 2 uses POM material, has the advantages that coefficient of friction is small, wearability is good, the installation of 2 mechanism of screw mandrel support seat
To above linear slider combination 9, the stability and fluency of overall operation are increased, for the branch for increasing respective numbers compared with long lead screw
Point, to reduce the influence compared with long screw because of gravity sag to numerically-controlled machine tool running precision.
The basic principles and main features and advantage of the utility model have been shown and described above.The technical staff of the industry
It should be appreciated that above-described embodiment does not limit the utility model in any form, it is all by the way of equivalent substitution or equivalent transformation
Technical solution obtained, all falls in the protection scope of the utility model.
