Abstract
The utility model relates to a kind of milling machine tailstock, comprise tailstock body, to be installed in tailstock body cavity interconnective screw mandrel and top, tailstock body is stretched out in rear end and the top front end of screw mandrel, screw mandrel rear end is connected with clip, the chamber inner bottom part of tailstock body is provided with the thrust bearing around screw mandrel, be provided with packing ring between the rear end of screw mandrel and the bottom outside of tailstock body, wrap up screw mandrel in the chamber of tailstock body and be toply provided with sleeve, top leading section is connected with workpiece.The beneficial effects of the utility model are: screw mandrel does not bend; Screw mandrel facing is not easy to wear; The factor that screw mandrel does not fracture; Large cutting force can be born; Sleeve screw is not easy to wear, destruction; The tailstock life-span strengthens greatly.
Description
Technical field
The utility model relates to a kind of milling machine tailstock.
Background technology
Milling machine is mainly used in milling spiral groove, and batch is large, requires that the single-piece work time is short.Small workpiece needs 2 ~ 3min; Larger workpiece needs about lOmin; Large workpiece about 20min.Original tailstock clamping force is inadequate, and Workpiece clamping comparatively bothers with unclamping, and the minor leading screw of use is very fast because bearing the wearing and tearing of comprehensive power, even fractures.
We are in daily milling machine operation, the blade of a cutter blank generally wants milling 2 ~ 64-helicla flute, dividing head is utilized to carry out repeatedly calibration work, and speed is fast, so the tailstock of milling machine is without locking device, the axial thrust load of cutting force is above the top screw mandrel passing to tailstock, and thus screw mandrel wearing and tearing are very fast.
There is following problem in existing tailstock: 1. screw mandrel easily bends; 2. screw mandrel facing is easy to wear; If 3. have impact in milling process, screw mandrel frangibility; 4. can not bear larger power, larger workpiece is just difficult to ensure processing; 5. the screwed hole installing screw mandrel is easily worn, destroys; 6. the tailstock life-span is poor.
Utility model content
The technical problems to be solved in the utility model is: based on the problems referred to above, provides a kind of milling machine tailstock.
The utility model solves the technical scheme that its technical problem adopts: a kind of milling machine tailstock, comprise tailstock body, be installed on screw mandrel interconnective in tailstock body cavity and top, tailstock body is stretched out in rear end and the top front end of screw mandrel, screw mandrel rear end is connected with clip, the chamber inner bottom part of tailstock body is provided with the thrust bearing around screw mandrel, between the rear end of screw mandrel and the bottom outside of tailstock body, packing ring is installed, wrap up screw mandrel in the chamber of tailstock body and be toply provided with sleeve, top leading section is connected with workpiece.
The beneficial effects of the utility model are: screw mandrel does not bend; Screw mandrel facing is not easy to wear; The factor that screw mandrel does not fracture; Large cutting force can be born; Sleeve screw is not easy to wear, destruction; The tailstock life-span strengthens greatly.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
Wherein: 1. clip, 2. screw mandrel, 3. packing ring, 4. thrust bearing, 5. tailstock body, 6. sleeve, 7. top.
Detailed description of the invention
By reference to the accompanying drawings the utility model is further described now.The schematic diagram that these accompanying drawings are simplification only illustrates basic structure of the present utility model in a schematic way, and therefore it only shows the formation relevant with the utility model.
A kind of milling machine tailstock as shown in Figure 1, comprise tailstock body 5, be installed on screw mandrel 2 interconnective in tailstock body 5 chamber and top 7, tailstock body 5 is stretched out in the rear end of screw mandrel 2 and the front end of top 7, screw mandrel 2 rear end is connected with clip 1, the chamber inner bottom part of tailstock body 5 is provided with the thrust bearing 4 around screw mandrel 2, be provided with packing ring 3 between the rear end of screw mandrel 2 and the bottom outside of tailstock body 5, wrap up screw mandrel 2 and top 7 in the chamber of tailstock body 5 and be provided with sleeve 6, the leading section of top 7 is connected with workpiece.
Clockwise shake clip 1, clamping work pieces; Counterclockwise shake clip 1, unclamps workpiece.
The stressing conditions of new screw mandrel greatly takes on a new look, and there are not other effects such as torque, and whole tailstock stressing conditions is good, and intensity ensures more.
Screw mandrel does not bend; Screw mandrel facing is not easy to wear; The factor that screw mandrel does not fracture; Large cutting force can be born; Sleeve screw is not easy to wear, destruction; The tailstock life-span strengthens greatly.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
