Abstract
The utility model provides a novel hollow lead screw which comprises a cylindrical lead screw body. One end of the lead screw body protrudes to be provided with a connection portion, and a water inlet through groove and a water outlet through groove are formed in the connection portion. During utilization of the novel hollow lead screw, a cooling liquid is fed into a water tube from the position of the water inlet through groove of the connection portion, flows in the lead screw through the water tube, returns to the connection portion of the lead screw from the outside of the water tube after reaching the front end, flows out of the water outlet through groove of the connection portion and returns to a cutting liquid tank from a water outlet joint of a cutting liquid tank body. According to the novel hollow lead screw, a cooling function of the lead screw can be improved without changing an original structure too much and changing a lead screw motor, and production costs are greatly reduced.
Description
Technical field
The utility model relates to the member of machining center lathe, especially relates to a kind of novel hollow screw mandrel.
Background technique
Widespread is in the every field of mechanical industry for screw mandrel, and its major function is that rotation motion is converted into straight line motion.Screw mandrel is made up of body, nut and ball usually.Friction directly takes place for leading screw and ball can produce heat, leading screw can be out of shape because of heat, influence its transmission accuracy, therefore require strict machine generally to use the hollow leading screw for the leading screw temperature rise, owing to can lead to oil or water cools off leading screw, so leading screw itself is difficult for heating, can effectively control temperature, reaches the stable accuracy purpose.
Hollow ball screw has the advantage of weight saving, so leading screw relatively is difficult for because of deadweight sagging excessively, and because the inertia of leading screw reduces, makes the drivings torsion reduction of motor; On the other hand, reach the usefulness that reduces the leading screw temperature owing to the hollow of leading screw partly can make freezing mixture flow through, so the temperature of leading screw can obtain preferable control.
The cooling liquid that makes screw mandrel cooling at present all is the circulation from the screw mandrel tail end to lead screw motor, so motor also must use hollow, and cost is higher.
The model utility content
The purpose of this utility model provides a kind of novel hollow screw mandrel, reduces production costs under the identical prerequisite of cooling effect.
Novel hollow screw mandrel provided by the utility model comprises columniform body, is provided with a junction from a distal process of the body of described screw mandrel, offers entry groove and water outlet groove on the described joint.
Novel hollow screw mandrel provided by the utility model in use, cooling liquid enters water pipe from the entry groove of joint, enter screw mandrel inside by water pipe, got back to the joint of screw mandrel behind the arrival front end again by the water pipe outside, flow out from the water outlet groove of joint, get back in the cutting fluid case from the water output connector of cutting fluid casing.
The original structure of novel macaroni yarn pole pair provided by the utility model need not to do too big change, also need not change lead screw motor, just can increase the function of screw mandrel cooling, greatly reduces cost of production.
Description of drawings
Fig. 1 is the structural drawing of novel hollow screw mandrel provided by the utility model.
Fig. 2 is the use phase diagram of novel hollow screw mandrel provided by the utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is elaborated.
Fig. 1 is the structural drawing of novel hollow screw mandrel provided by the utility model.Novel hollow screw mandrel provided by the utility model comprises columniform body 1, and a distal process of screw mandrel body 1 is provided with a junction 2, offers entry groove 3 and water outlet groove 4 on the joint 2.
Fig. 2 is the use phase diagram of novel hollow screw mandrel provided by the utility model.Arrow among the figure is represented the flow direction of cooling liquid.This novel screw mandrel in use, gland 6 and the joint 2 of screw mandrel 1 tail end agree with, cooling liquid enters water pipe 5 by the entry groove place 3 of joint 2, enter screw mandrel 1 inside by water pipe 5, got back to the joint 2 of screw mandrel 1 behind the arrival front end again by water pipe 5 outsides, flow out from the water outlet groove 4 of joint 2, get back in the cutting fluid case from the water output connector 8 of cutting fluid casing 7.
The original structure of this novel macaroni yarn pole pair need not to do too big change, also need not change lead screw motor, just can increase the function of screw mandrel cooling, greatly reduces cost of production.
