Abstract
The utility model relates to a rolling unloading device for a machine tool, which belongs to the field of machine tools. The rolling unloading device is provided with a moving component, and is characterized in that a fixing nut is fixedly connected onto the moving component via a screw, combined butterfly springs which are paired are mounted between an adjusting screw stem and a positioning rod, the positioning rod and the combined butterfly springs can freely move in the adjusting screw stem at a certain distance, the moving component is mounted on a guide track of a fixed component, and a bearing block which is provided with a set of supporting type needle roller bearings is mounted at the lower end of the adjusting screw stem. The rolling unloading device effectively eliminates machine tool crawling, adjusts deformation of the butterfly springs manually by the aid of the screw stem, is simple and convenient, does not need operation media such as guide track oil and the like, and is economical and environment-friendly. Due to a part of gravity, two components are always attached by means of being abutted with the guide track, and movement precision keeps unchanged.
Description
Technical field
The utility model relates to machine tool field, especially a kind ofly eliminates the lathe rolling unloading device that lathe is creeped.
Background technology
As everyone knows, at present, in machine industry, particularly heavy slightly lathes, when mobile, because gravity is too big, load is too high, and frictional resistance is too big, very easily produces and creeps, and influences the machine tool motion precision.Current more common way: utilize the static pressure technology, produce crossing current hydraulic oil, produce and float oil film, thereby reduce moving resistance by multi-head pump.The shortcoming of this mechanism: increased multi-head pump and hydraulic part, cost improves greatly; Complex structure, relevant components and parts are too many, the fault rate height; The floatation volume of oil film changes, and is difficult for regulating control; The operation medium is a hydraulic oil, leaks easily, and contaminated environment increases cost.
Summary of the invention
In order to overcome the deficiencies in the prior art, the utility model provides a kind of lathe rolling unloading device, effectively eliminates lathe and creeps, and screw rod is regulated the butterfly spring deflection manually, and is simple and convenient; Do not need guide rail wet goods operation medium, economic environmental protection; Because sharing is a part of gravity, to fit by guide rail all the time between two parts, kinematic accuracy remains unchanged.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of lathe rolling unloading device, be provided with moving-member, it is characterized in that hold-down nut is fixed on the moving-member by screw attachment, the combination butterfly spring that pairing is good is installed between adjusting screw(rod) and the backstay, backstay and combination butterfly spring are free to move a part of distance in adjusting screw(rod), moving-member is installed on the guide rail of fixed part, and the bearing block that a cover support type needle roller roller bearing is housed is equipped with in the adjusting screw(rod) lower end.
The beneficial effects of the utility model are, effectively eliminate lathe and creep, and screw rod is regulated the butterfly spring deflection manually, and is simple and convenient; Do not need guide rail wet goods operation medium, economic environmental protection; Because sharing is a part of gravity, to fit by guide rail all the time between two parts, kinematic accuracy remains unchanged.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a structural representation of the present invention
1. moving-members among the figure, 2. adjusting screw(rod), 3. hold-down nut, 4. backstay, 5. combination butterfly spring, 6. bearing block, 7. support type needle roller roller bearing, 8. fixed part.
The specific embodiment
In Fig. 1, the utility model earlier with hold-down nut 3, was fixed on the moving-member 1 by screw attachment before moving-member 1 does not install to fixed part 8.The good combination butterfly spring 5 that will match is again packed between adjusting screw(rod) 2 and the backstay 4, and backstay 4 and combination butterfly spring 5 are free to move a part of distance in adjusting screw(rod) 2, but can not throw off.Moving-member 1 is installed on the guide rail of fixed part 8, be raised to adjusting screw(rod) 2 topmost after, pack into the bearing block 6 of a cover support type needle roller roller bearing 7 be housed.Because adjusting rod 2 is that sphere contacts with bearing block 6, so can eliminate stress and the motion torsional deflection.
Be exactly regulating action power size at last, adjusting screw(rod) 2 is turned towards the guide rail direction, the distortion of compression butterfly spring, make a part of gravity of moving-member affact on the support type needle roller roller bearing 7, allow sliding friction be converted into rolling friction, reduce frictional resistance, but strength can not be excessive, do not allow moving-member jack-up, the getaway contact influences machine tool accuracy.
Adopt this can effectively eliminate and creep, and only need turn just energy regulating action power size of adjusting screw(rod) with frame mode, easy to operate.Butterfly spring also has the effect of the sudden change of minimizing stress impact, does not need the medium of hydraulic oil, and is simple and practical.
