Abstract
The utility model discloses a spring tip installed on a tailstock of a machine tool. Several spiral grooves are correspondingly arranged on the surface of a center and a circular conical surface of a 60 degrees cone with the centre is installed on the circular conical surface. An oil sink and an oil hole communicating with the top of the tip are arranged on the cylinder of the spring tip and an oil bottle is arranged at the oil entry of the oil sink or the oil hole. The helicoids of the spiral grooves on the surface of the centre and circular conical surface of the utility model maintains a good contact with a small ellipticity of the manufacturing workpieces. An oil sink and an oil hole are equipped on the cylinder of the tip and communicate with the centre and oil bottles at the oil entry of the oil sink and oil hole to lubricate automatically and manufacture workpieces with high efficiency, high accuracy and a high rotating speed.
Description
Technical field
The utility model relates to the parts of lathe, especially a kind of lathe center that is installed on the tailstock tool.
Background technology
Be installed on that passive thimble is that indispensable parts are processed in metal cutting on the tailstock tool.Currently used fixed thimble is directly to be installed in the apical axis, it is by the Morse's cone body that contacts with apical axis, top, 60 ° of top cones are installed, cylinder is formed between Morse's cone body and 60 ° of cones, has the positioning accuracy height, the advantage that bearing capacity is strong, but be sliding friction between the thimble of this kind structure and the centre bore of workpiece to be machined, poor lubrication easily produces high temperature, thereby scaling loss workpiece, therefore this thimble can not carry out high-speed cutting, and increases the non-cutting time that refuel in the workpiece centre hole, and efficiency is low.
Summary of the invention
Can only hang down quick-action commentaries on classics processing in order to overcome existing fixedly thimble, poor lubrication, the deficiency that efficiency is low, the utility model provides a kind of lathe center, and processing is changeed in the not only suitable high quick-action of this lathe center, and energy self-lubricate, the workpiece ovality of processing is little, adapt to current machining high accuracy, high rotating speed, high efficiency processing request.
The technical scheme that the utility model technical solution problem is adopted is: on top surface and install that correspondence is provided with some helicla flutes on the taper seat of 60 ° of top cones, be provided with angle between helicla flute and the thimble axis, the thimble cylinder is provided with and is communicated with top oil groove or oilhole, and oil-feed place of oil groove or oilhole is provided with lubricating cup.The spiral fluted helicoid that is provided with on the taper seat of the top surface of the utility model and 60 ° of cones has good the contact with the processing work centre bore, and the workpiece ovality of processing is little.The thimble cylinder is provided with the lubricating cup that oil-feed place that is communicated with top oil groove or oilhole and oil groove or oilhole is provided with, and can realize self-lubricate.
The beneficial effects of the utility model are: the utlity model has the positioning accuracy height, bearing capacity is strong, suitable high-speed cutting, and self-lubricate reduces the non-cutting time that refuel in the workpiece centre hole, the advantage that efficiency is high.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further specified.
Fig. 1 is a front view of the present utility model.
Fig. 2 is the right view of Fig. 1.
1. Morse's cone bodies are 2. top among the figure, 3.60 ° of cones, 4. cylinder, 5. helicla flute, 6. oilhole, 7. lubricating cup.
The specific embodiment
At Fig. 1, among Fig. 2, lathe center is by the Morse's cone body (1) that contacts with apical axis, top (2), 60 ° of cones (3) of top (2) are installed, be positioned at cylinder (4) composition between Morse's cone body (1) and the 60 ° of cones (3), the utility model embodiment is on top (2) surface and branch such as correspondence is installed on the taper seat of 60 ° of cones (3) of top (2) 3 helicla flutes (5) are set, angle α between helicla flute and the thimble axis is 29 °, can be provided with the oil groove that is communicated with top oil on the thimble cylinder through the conical surface of 60 ° of cones, also can be provided with through needle body inside and be communicated with top oilhole by the thimble cylinder, the utility model is preferential to be adopted to go up at thimble cylinder (4) and is provided with the oilhole (6) that is communicated with top (2) through needle body inside, is provided with lubricating cup (7) in oil-feed place of the lip-deep oilhole of thimble cylinder (4) (6).The helicla flute (5) that is provided with on the taper seat of top (2) surface and 60 ° of cones (3) is because of its helicoid contacts no gap with the processing work centre bore, so the workpiece ovality of processing is little.Lubricating oil in the lubricating cup (7) reaches to top (2) through oilhole (6), can realize self-lubricate to top (2) and processing work.The utility model can adapt to current machining high accuracy, high rotating speed, high efficiency processing request.
Claims (3)
1, a kind of lathe center, by the Morse's cone body that contacts with apical axis, top, 60 ° of top cones are installed, cylinder is formed between Morse's cone body and 60 ° of cones, it is characterized in that: on top surface and install that correspondence is provided with some helicla flutes on the taper seat of 60 ° of top cones, be provided with angle between helicla flute and the thimble axis, the thimble cylinder is provided with and is communicated with top oil groove or oilhole, and oil-feed place of oil groove or oilhole is provided with lubricating cup.
2, a kind of lathe center according to claim 1 is characterized in that: described on top surface and correspondence is installed on the taper seat of 60 ° of top cones to be provided with some helicla flutes be the 2-6 bar.
3, a kind of lathe center according to claim 1 and 2 is characterized in that: the angle α angle that is provided with between described helicla flute and the thimble axis is 28-30 °.
