Abstract
The utility model discloses a cold system of lead screw cavity oil, the ball screw who includes emptying aperture in being equipped with along the axial, ball screw's well emptying aperture one end is passed through the oil blanket and is formed sealedly, the other end supplies the coolant liquid pipe to insert, the outstanding ball screw of one end of coolant liquid pipe forms the coolant liquid inlet, emptying aperture and keep the clearance to form reverse mouthful with the oil blanket during the other end is deep, the cooling flow channel that the clearance formed the coolant liquid has between the outer wall of coolant liquid pipe and the inner wall of well emptying aperture, the liquid outlet that forms cooling flow channel between male one end and the coolant liquid outside of tubes wall is managed to well emptying aperture cooling but liquid, the coolant liquid enters into the coolant liquid intraduct through the inlet of coolant liquid pipe, and the reverse mouthful of entering cooling flow channel that flows who follows the coolant liquid pipe cools off the back to ball screw and flow from the liquid outlet. The utility model discloses it forms cooling flow channel to combine together the coolant liquid pipe with ball screw to by freezing liquid collecting vat carries out cyclic utilization, resources are saved to the coolant liquid.
Description
Technical field
This utility model relates to chiller, is specifically related to a kind of screw mandrel hollow oil cooling system.
Background technology
One of key element of lathe work, is there is required cutting thrust and cutting counter-force in processing.Motor makes ballscrew shaft rotate as power source, thus being converted into axially driving, ball-screw at this moment has two effects: one is driving effect；Two is producing processing required cutting thrust while, bears the effect of cutting counter-force even load.The pitch of ball-screw is different because of helical pitch (each revolution of displacement), by pitch, the rotation peripheral force of motor is converted to axial force, namely also playing a part reductor, make only small motor also can produce very big axial force, ball-screw is strictly a kind of very important mechanical part.Ball-screw-transmission system, traffic direction has higher rigidity, there is higher precision and relatively low noise simultaneously, having higher centripetal force, but speed and acceleration are relatively low, maintenance requirement is also of a relatively high, during ball screw temperature rise, thermal stress effects can make elongate screw, makes the length of screw rod become unstable, it is therefore necessary to adopt the mode of cooling to prevent temperature rise.
Summary of the invention
Goal of the invention: for the deficiencies in the prior art, this utility model provides a kind of screw mandrel hollow oil cooling system, can ball screw be cooled down effectively.
Technical scheme: screw mandrel hollow oil cooling system described in the utility model, including the ball screw being provided with hollow hole vertically, it is characterized in that: hollow hole one end of described ball screw is formed by oil sealing and seals, the other end inserts for coolant pipe, one end of described coolant pipe highlights described ball screw and forms coolant inlet, the other end gos deep into described hollow hole and keeps gap to form reverse mouth with described oil sealing, there is between outer wall and the inwall of described hollow hole of described coolant pipe gap and form the coolant flow channel of coolant, described hollow hole forms the liquid outlet of described coolant flow channel between one end and the described coolant pipe outer wall for the insertion of described coolant pipe；Coolant enters into inside described coolant pipe through the inlet of described coolant pipe, exits into from the reverse mouth of described coolant pipe and flows out from liquid outlet after described ball screw is cooled down by described coolant flow channel.
Further mature technology scheme, the inlet of described coolant pipe is connected with coolant input equipment, and the liquid outlet of described cooling liquid flowing channel is connected with coolant collecting tank, is connected with coolant input equipment after the cooled case of coolant collecting tank.
Further, coolant is inputted to inlet by described coolant input equipment by oil pump.
Further, described ball screw two ends diameter shrinks in staged boss-shaped, and described oil sealing and described ball screw port diameter match.
Beneficial effect: compared with prior art, advantage of the present utility model: this utility model designs cooling system by the construction features for ball screw, coolant pipe combines with ball screw formation coolant flow channel, and by coolant collecting tank, coolant is circulated utilization, economizes on resources.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Detailed description of the invention
Below by accompanying drawing, technical solutions of the utility model are described in detail.
Embodiment 1:Screw mandrel hollow oil cooling system as shown in Figure 1, including the ball screw being provided with hollow hole vertically, hollow hole one end of ball screw forms sealing by oil sealing 14, the other end inserts for coolant pipe 1, ball screw two ends diameter shrinks in staged boss-shaped, and oil sealing 14 and ball screw port diameter match；The prominent ball screw in one end of coolant pipe 1 forms coolant inlet 11, the other end gos deep into hollow hole and keeps gap to form reverse mouth 12 with oil sealing 14, having gap between outer wall and the inwall of hollow hole of coolant pipe 1 and form the coolant flow channel of coolant, hollow hole forms the liquid outlet 13 of coolant flow channel between one end and coolant pipe 1 outer wall for coolant pipe 1 insertion.The inlet 11 of coolant pipe 1 is connected with coolant input equipment, and the liquid outlet 13 of cooling liquid flowing channel is connected with coolant collecting tank, is connected with coolant input equipment after the cooled case of coolant collecting tank.Coolant is inputted to inlet 11 by coolant input equipment by oil pump, it is internal that the inlet 11 of the cooled liquid pipe 1 of coolant enters into coolant pipe 1, exit into from the reverse mouth 12 of coolant pipe 1 and flow out to coolant collecting tank from liquid outlet 13 after ball screw is cooled down by coolant flow channel, send coolant input equipment after the cooling of cooled case back to and be repeated utilizing.
Although as it has been described above, represented and described this utility model with reference to specific preferred embodiment, but it shall not be construed as the restriction to this utility model self.Under the spirit and scope premise of the present utility model defined without departing from claims, it can be made in the form and details various change.
