Abstract

The utility model discloses an adjustable slant head lathe tool handle which can effectively prevent a shaft body workpiece in a high-speed revolution from entering a main shaft sleeve and scuffing a main shaft, and ensure machining precision of a workpiece. The adjustable slant head lathe tool handle comprises a knife handle body and a blade bearing, wherein the upper end face of the knife handle is provided with a horizontal sliding groove, the blade bearing is installed in the sliding groove through a lug at the bottom of the blade bearing, and the blade bearing can move along the direction of the sliding groove. A lathe tool is installed on the top of the blade bearing. When the adjustable slant head lathe tool handle is used, the knife handle body is installed on a fixed tool head, and the direction of the sliding groove is parallel to a centre line of a lathe main shaft. After a fitting seat slides in the sliding groove to a setting position, the fitting seat is fixed through stop screws. After the lathe tool is installed, the adjustable slant head lathe tool handle can adjust the position of the blade bearing to ensure that a certain distance L between the lathe tool and the end potion of the main shaft sleeve exists, and can ensure that a cutting portion of the workpiece to be cut is not enabled to turn back to the inner of the main shaft sleeve in the process of cutting.

Description

A kind of adjustable inclined to one side knife turning tool handle
Technical field
The utility model relates to a kind of handle of a knife, is specifically related to a kind of adjustable inclined to one side knife turning tool handle that is used in the rip cutting formula lathe, belongs to the Machining Technology field.
Background technology
At present, in rip cutting processing, normal operation straight tool handle mounting cutter carries out machining.But move because rip cutting formula lathe work in-process lathe spindle does not does not come and go, finish processing but make workpiece do back and forth movement by its inner collet mechanism.Adopt the straight tool handle in traditional rip cutting formula lathe, handle of a knife is installed on the fixing knife rest, and handle of a knife is vertical with spindle centerline, and lathe tool is installed in the end of handle of a knife, and lathe tool and rack sleeve end face are in same vertical plane.In the lathe grinding process, workpiece is done back and forth movement, the situation that workpiece carries out main shaft inside can occur.A problem can appear thus: when workpiece turns back to lathe spindle inside, the iron filings at workpiece step place can be brought in the rack sleeve, damage rack sleeve, thereby so that machine tool capability and precise decreasing, equally also can have influence on precision and the surface quality of workpiece to be machined.
In order to solve problems, must improve the structure of cutter or lathe, but the structure of change lathe is relatively difficult, and wastes time and energy, therefore need to improve cutter in the rip cutting formula lathe, to avoid processing iron filings to the impact of lathe and machining accuracy.
Summary of the invention
In view of this, the utility model provides a kind of adjustable inclined to one side knife turning tool handle, adopts this handle of a knife can be under the prerequisite that does not change machine tool structure, and iron filings are on the wearing and tearing of rack sleeve and on the impact of workpiece to be machined precision in effectively avoiding processing.
The adjustable inclined to one side knife turning tool handle that the utility model provides comprises handle of a knife body and blade bearing, and ancillary equipment is lathe spindle, knife rest and blade.Its annexation is: be processed with the chute of level in the upper surface of handle of a knife body, blade bearing is installed in the chute of handle of a knife body by the projection cooperation of its bottom, and blade bearing can move along the chute direction.Blade bearing is fixed by stop screw in chute.Blade is installed in the top of blade bearing.The handle of a knife body is installed on the fixing knife rest, makes the direction of chute parallel with the center line of lathe spindle.
The cross section of described handle of a knife body upper hopper chute is right-angled trapezium, and stop screw is positioned on the vertical plane of chute right angle end.Beneficial effect:
(1) the utility model makes in the process lathe tool end depart from the rack sleeve certain distance by the lathe tool mount pad, workpiece can not turn back to lathe spindle inside in working angles, avoid the work in-process iron filings on the impact of rack sleeve wearing and tearing, guarantee the machining accuracy of lathe.
(2) lathe tool mount pad and Connection Block are slidingly matched by chute, thereby can adjust distance between lathe tool end and the rack sleeve according to the length of workpiece to be cut, to satisfy the workpiece to be cut of different length, so that the scope of application of knife turning tool handle is wider partially.
Description of drawings
Fig. 1 is the structural representation of inclined to one side knife turning tool handle;
Fig. 2 is the scheme of installation of inclined to one side knife turning tool handle;
Fig. 3 is inclined to one side knife turning tool handle and the installation Comparison figure of straight tool handle in rip cutting formula lathe.
Wherein, 1-handle of a knife body, 2-workpiece to be cut, 3-rack sleeve, 4-knife rest, 5-straight tool handle, 6-lathe spindle, 7-blade, 8-blade bearing.
The specific embodiment
Below in conjunction with the accompanying drawing embodiment that develops simultaneously, the utility model is described in detail.
Present embodiment improves existing straight tool handle 5, a kind of inclined to one side knife turning tool handle is provided, make in process blade 7 ends depart from rack sleeve 3 certain distance L, thereby avoid that iron filings enter in the rack sleeve 3 in rip cutting formula lathe processing, wear spindle sleeve 3 and affect the machining accuracy of workpiece 2 to be cut.
The structure of the inclined to one side knife turning tool handle that present embodiment provides comprises handle of a knife body 1 and blade bearing 8 as shown in Figure 1, and ancillary equipment is lathe spindle 6, knife rest 4 and blade 7.Its annexation is: be processed with the chute of level in the upper surface of handle of a knife body 1, the cross section of chute is right-angled trapezium.Blade bearing 8 is installed in the chute of handle of a knife body 1 by the projection cooperation of its bottom, and blade bearing 8 can move along the chute direction.Blade bearing 8 is fixed by stop screw in chute.Blade 7 is installed in the top of blade bearing 8.
When using this handle of a knife handle of a knife body 1 is installed on the fixing knife rest 4, makes the direction of handle of a knife body 1 upper hopper chute parallel with the center line of lathe spindle.The length sliding blade seat 8 of foundation workpiece 2 cutting tips to be cut comes the distance L between adjustable blade 7 and rack sleeve 3 ends, as shown in Figure 2.Distance L should guarantee that the cutting tip of workpiece 2 to be cut in working angles can not turn back to the inside of lathe spindle 6.When the processing work, the iron filings that can effectively avoid workpiece to enter when back and forth movement causing in the rack sleeve scratch main shaft with the inclined to one side knife turning tool of this kind form.
Partially knife turning tool handle and the traditional installation Comparison of straight tool handle 5 in rip cutting formula lathe are as shown in Figure 3.
In sum, more than be preferred embodiment of the present invention only, be not for limiting protection scope of the present invention.Within the spirit and principles in the present invention all, any modification of doing, be equal to replacement, improvement etc., all should be included within protection scope of the present invention.
