Abstract
The utility model discloses an extension carriage of a lathe. The extension carriage is rectangular; a U-shaped opening or a rectangular hole is formed on one side of the rectangular extension carriage and used for allowing a tool shank of a turning tool to be inserted in; a fastening part is arranged at the upper end of the U-shaped opening or the rectangular hole; a supporting part is arranged at the lower end of the U-shaped opening or the rectangular hole; and the extension carriage is clamped on a rotary carriage table of the lathe and extends out of the rotary carriage table of the lathe. The extension carriage adopts an independent part, is installed on the rotary carriage table of the lathe and extends out of the rotary carriage table of the lathe at a distance, thereby effectively suppressing the vibration of the extension carriage; by adopting the extension carriage, not only can the machining accuracy of the lathe be enhanced to the deep notch on the larger workpiece, but also the service life of the lathe is prolonged, and the potential safety hazards are eliminated at the same time. The extension carriage has the characteristics of simple structure, convenience in use, good turning effect of the deep notch, and the service life of the turning tool is greatly prolonged.
Description
Technical field
The utility model relates to a kind of lathe cutter saddle, is specifically related to a kind of prolongation knife rest that is installed on the lathe.
Background technology
Structure at existing lathe intermediate slide is all roughly similar, and lathe tool is installed on the knife rest of lathe, is used for surface and some more shallow grooves of turner.This structure is without a doubt for the processing of general workpiece, but in the time of need processing darker groove for the bigger workpiece of some physical dimensions, because the knife bar of lathe tool long (being equivalent to long cantilever beam), turning add man-hour knife bar be easy to generate distortion, the vibration, if be mingled with hard point etc. in the workpiece, be easy to lathe tool is fractureed.So both can have influence on the crudy of workpiece, also exist serious potential safety hazard simultaneously.Therefore, be necessary the cutter frame structure of existing lathe is improved.
The utility model content
The purpose of this utility model is to overcome defective of the prior art, and a kind of improvement structure of turning tool rest is provided, and when the deep trouth of turning large-scale workpiece, knife bar is not yielding, frangibility not in this structure, but also can improve the machining accuracy of workpiece.
For achieving the above object, the technical solution adopted in the utility model is that a kind of lathe prolongs knife rest, it is characterized in that, described prolongation knife rest is a rectangle, a side that prolongs knife rest at described rectangle is provided with U-shaped opening or rectangular opening, described U-shaped opening or rectangular opening be used to pack into the handle of a knife of lathe tool is provided with securing member in the upper end of described U-shaped opening or rectangular opening, is provided with support member in the lower end of described U-shaped opening or rectangular opening; Described prolongation knife rest is clamped on the rotatable knife rest platform of lathe, and stretches out the rotatable knife rest platform of described lathe.
Prolong on the knife rest for the ease of lathe tool is clamped in, wherein preferable technical scheme is, described securing member is a fastening bolt, and described fastening bolt has 2 at least.
For the structure of simplifying support member and the length of being convenient to regulate support member, so that this prolongation knife rest uses on the lathe of different model, preferable technical scheme can also be, described support member is a screw rod, one end of described screw rod is connected with the lower end of described U-shaped opening or rectangular opening, is connected with nut at the other end of described screw rod.
For the structure of simplifying support member and the length of being convenient to regulate support member, so that this prolongation knife rest uses on the lathe of different model, preferable technical scheme can comprise that also described nut is connected with leg, or described nut and leg are made an overall structure.
For the ease of described prolongation knife rest is installed, and when turner not and produce the movement interference problem between the workpiece, preferable technical scheme can comprise that also the width of described prolongation knife rest is slightly larger than the width of lathe tool knife bar.
Advantage of the present utility model and beneficial effect are: because this prolongation knife rest is independently parts, be installed in extended knife rest platform one segment distance on the knife rest platform of lathe, both be equivalent to talk about and driedly prolonged one section, be provided with support member in the lower end that prolongs frame simultaneously, effective like this trembling of slowing down knife rest, most of length in the cantilever beam is become be simply supported beam, make knife bar stressed more reasonable, this structure both can improve the machining accuracy of lathe to deep trouth on the big workpiece, can prolong the service life of lathe tool again, also can eliminate safe hidden trouble simultaneously.Owing to being connected on the screw rod that prolongs the knife rest lower end adjusting nut is housed again, under nut, be connected with leg, can regulate the prolongation knife rest to the distance between the lathe slip crate upper table surface by regulating this nut, this prolongation knife rest be used on the lathe of different model to be applicable to.This prolongation knife rest has simple in structure, easy to use, turning deep trouth effective, the characteristics such as service life that can prolong lathe tool.
Description of drawings
Fig. 1 is the structural representation that the utility model lathe prolongs knife rest.
Among the figure: 1, prolong knife rest; 2, U-shaped opening or rectangular opening; 3, rotatable knife rest platform; 4, fastening bolt; 5, screw rod; 6, nut; 7, leg; 8, lathe slip crate upper table surface.
The specific embodiment
Below in conjunction with drawings and Examples, the specific embodiment of the present utility model is further described.Following examples only are used for the technical solution of the utility model more clearly is described, and can not limit protection domain of the present utility model with this.
Embodiment 1
As described in Figure 1, the utility model is a kind of prolongation knife rest 1 of lathe, this prolongs knife rest 1 is rectangle, a side that prolongs knife rest 1 at described rectangle is provided with U-shaped opening or rectangular opening 2, described U-shaped opening or rectangular opening 2 be used to pack into the handle of a knife of lathe tool, upper end at described U opening or rectangular opening 2 is provided with securing member, is provided with support member in the lower end of described U-shaped opening or rectangular opening 2; Described prolongation knife rest 1 is clamped on the rotatable knife rest platform 3 of lathe, and stretches out the rotatable knife rest platform 3 of described lathe.
On the basis of embodiment 1, for the ease of being clamped in, lathe tool prolongs on the knife rest 1, and preferred embodiment is in the utility model, described securing member is a fastening bolt 4, described fastening bolt 4 has 2, and this fastening bolt 4 can be used for lathe tool is clamped, and the structure of all the other and embodiment 1 is identical.
