Description

Draw nest fixture in a kind of aperture

Technical field

The utility model is related to clamping tool for machine work technical field, and nest fixture is drawn in specially a kind of aperture, can be achieved accurate Control aperture to draw nest depth and draw nest diameter.

Background technology

In mechanical processing process, often after plane or circumference drilling, aperture needs to draw a nest a × α ° chamfering. The conventional processing mode used is to draw socket drill head by bench drill clamping to be processed, and the depth of chamfering and restricted diameter add in bench drill Work mode, it is difficult in the margin of tolerance for being accurately controlled in design data requirement.

The content of the invention

The purpose of this utility model is exactly to solve to draw in nest process at present, draws nest depth and diameter is difficult to accurate control Problem.Based on this, a kind of simple in construction, adjustment stroke work holdup tool easy to control, available for when drawing nest, according to design money is proposed The positioner for drawing nest depth or diameter adjustment stroke nest cutter needed for expecting, the accurate processing to complete stroke nest, with fixed Position precision is high, the reliable and stable advantage of crudy.

The technical solution of the utility model is：

Nest fixture is drawn in a kind of aperture, including draws nest cutter 1, it is characterised in that：Also include axial sleeve 2；

The axial sleeve 2 is axially engaged with drawing nest cutter 1, and drawing nest cutter 1 can move axially in axial sleeve 2, And nest cutter 1 and the secure fit of axial sleeve 2 can will be drawn by adjusting screw 4；Axial sleeve 2 is close to stroke cutter head of nest cutter 1 One end side be provided with chip removal window 3.

Draw nest fixture in a kind of further preferred scheme, aperture, it is characterised in that：Axial sleeve 2 is close to a stroke nest knife It is positioning end face 6 to have the end face of 1 cutter head, and the positioning end face 6 can be brought into close contact with drawing work holdup part 5.

Draw nest fixture in a kind of further preferred scheme, aperture, it is characterised in that：Draw and marked on the knife bar of nest cutter 1 There is scale.

Draw nest fixture in a kind of further preferred scheme, aperture, it is characterised in that：Adjusting screw 4 is arranged on axially Sleeve 2 is away from the end face side wall for drawing the cutter head of nest cutter 1.

Draw nest fixture in a kind of further preferred scheme, aperture, it is characterised in that：The central shaft hole of axial sleeve 2 is With drawing the ladder hole that the cutter head of nest cutter 1 and knife bar coordinate.

Beneficial effect

The beneficial effects of the utility model are：By increasing the side of positioning sleeve 2 in first 1 diametric(al) of existing stroke of socket drill Method, solves to draw nest depth and diameter accuracy control problem.By changing the diameter of bore of sleeve 2, the diameter of bore model can be solved Enclose interior all processing contents that need to control to draw nest diameter or depth.The utility model is simple to manufacture, and can solve various apertures Eat dishes without rice or wine draw a nest problem, the scope of application is wide.

Additional aspect and advantage of the present utility model will be set forth in part in the description, partly by from following description In become obvious, or by it is of the present utility model practice recognize.

Brief description of the drawings

Of the present utility model above-mentioned and/or additional aspect and advantage will from description of the accompanying drawings below to embodiment is combined Become substantially and be readily appreciated that, wherein：

Fig. 4：Tube-in-tube structure sectional view.

Wherein：1st, nest cutter is drawn；2nd, sleeve；3rd, chip removal window；4th, adjusting screw；5th, work holdup part is drawn；6th, end face is positioned.

Embodiment

Embodiment of the present utility model is described below in detail, the example of the embodiment is shown in the drawings, wherein from beginning Same or similar element or element with same or like function are represented to same or similar label eventually.Below by ginseng The embodiment for examining accompanying drawing description is exemplary, it is intended to for explaining the utility model, and it is not intended that to the utility model Limitation.

In description of the present utility model, it is to be understood that term " " center ", " longitudinal direction ", " transverse direction ", " length ", " width Degree ", " thickness ", " on ", " under ", "front", "rear", "left", "right", " vertical ", " level ", " top ", " bottom ", " interior ", " outer ", The orientation or position relationship of the instructions such as " clockwise ", " counterclockwise " be based on orientation shown in the drawings or position relationship, be only for It is easy to description the utility model and simplifies describe, rather than to indicate or imply that signified device or element must have specific Orientation, with specific azimuth configuration and operation, therefore it is not intended that to limitation of the present utility model.

As shown in figure 1, the utility model proposes aperture draw nest fixture and include drawing a nest cutter 1, in addition to for axial essence It is determined that the axial sleeve 2 of position.

The axial sleeve 2 with draw a nest cutter 1 axially engage, the central shaft hole of axial sleeve 2 be with draw the cutter head of nest cutter 1 and The ladder hole that knife bar coordinates.Drawing nest cutter 1 can move axially in axial sleeve 2, and axial sleeve 2 is close to a stroke nest cutter 1 The one end side of cutter head is provided with chip removal window 3, it is ensured that draw the smooth chip removal of nest cutter 1 on the premise of, by adjust axial sleeve 2 with The relative axial position of nest cutter 1 is drawn, and nest cutter 1 and the secure fit of axial sleeve 2 will be drawn by adjusting screw 4, makes axial direction The end face axial of sleeve 2 is accurately positioned, so that drawing nest cutter 1 and axial sleeve 2 end face one controllable diameter of formation and depth The effective workspace of cutter, the nest of drawing that can then complete controllable diameter and depth is processed.

Further, it is described as shown in Fig. 2 axial sleeve 2 is positioning end face 6 close to the end face of the cutter head of nest cutter 1 is drawn Positioning end face 6 has best bright finish, can be brought into close contact with drawing work holdup part 5, so as to be further ensured that axially position precision.

Further, determine to draw nest depth and diameter for convenience, drawing to mark on the knife bar of nest cutter 1 has.

The utility model is especially able to the control problem that nest depth and diameter are drawn after forging and casting end face or excircle drilling Although thoroughly solving that embodiment of the present utility model has been shown and described above, it is to be understood that above-described embodiment is Exemplary, it is impossible to it is interpreted as to limitation of the present utility model, one of ordinary skill in the art is not departing from the utility model Principle and objective in the case of above-described embodiment can be changed in the range of the utility model, change, replace and Modification.
