Description

Staight shank path endoporus fine adjustment fine boring cutter

Technical field

The utility model is related to parts manufacture field, particularly a kind of staight shank path endoporus fine adjustment fine boring cutter.

Background technology

At present, path inner hole refined boring cutter is widely used in machining and production process usually.But it is existing small The degree of regulation of footpath inner hole refined boring cutter is relatively low, while blade bearing uses weldment, the maximum load that can be carried is low, and the depth of bore hole Degree is also smaller.Therefore the precision of processing is relatively low and can not accurately process high depth small size pores as needed.

Because in consideration of it, special propose this utility model.

Utility model content

The purpose of this utility model be to provide it is a kind of can be with the fine boring cutter for path endoporus of fine adjustment.

To achieve these goals, a kind of staight shank path endoporus fine adjustment fine boring cutter that the utility model is provided, its feature exists In the fine boring cutter includes right boring body, adjusting means and blade bearing；The right boring body includes boring head and handle of a knife；Handle of a knife quilt It is configured in boring head afterbody and boring head and handle of a knife is integrated；The blade bearing uses casting；The bore hole of the fine boring cutter adds Work precision is ± 0.01mm.

It is preferred that, boring head one end of the right boring body is configured with a through hole.

It is preferred that, the adjusting means includes dial, dish-like shell fragment, clamp nut, copper nut and movable axis, the quarter Scale, dish-like shell fragment, clamp nut, copper nut and movable axis are sequentially connected and pass through the through hole of the right boring body.

It is preferred that, the adjusting means is connected by lock screw with blade bearing.

It is preferred that, the tooth of the dial is away from for 0.25mm.

It is preferred that, the right boring body, the machining accuracy of adjusting means are ± 0.01-0.02mm.

What the utility model was provided, have the advantages that：

Blade bearing uses cast member, and intensity is higher, and the maximum load that can be carried is bigger, and operating efficiency is higher, and precision is more It is high.

The machining accuracy of fine boring cutter part reaches ± 0.01-0.02mm, and scale is molar away from for 0.25mm, makes the processing of boring cutter Precision can reach ± 0.01mm.

In figure：

1. the blade bearing of 2. dial of right boring body, 3. 5. copper nut of dish-like 4. clamp nut of shell fragment, 6. movable axis 7. 8. lock screw

Embodiment

In order that those skilled in the art more fully understand the utility model scheme, below in conjunction with the accompanying drawings and specific implementation The utility model is described in further detail for mode.

Fig. 1-2 is refer to, a kind of staight shank path endoporus fine adjustment fine boring cutter, including right boring body 1, tune is present embodiments provided Regulating device and blade bearing 7.

Right boring body 1 includes boring head and handle of a knife, and boring head and handle of a knife are integrated, and handle of a knife is built in the tail of boring head Portion.Handle of a knife is connected with boring machine.Long straight handle of a knife is processed to the small size pores of long depth.

Boring head one end of right boring body 1, which is configured with one, is used for the through hole of device for installing and adjusting.

Adjusting means includes dial 2, dish-like shell fragment 3, clamp nut 4, copper nut 5 and movable axis 6.Dial 2 includes Card, the centrally disposed screw rod of card, screw rod passes through dish-like shell fragment 3, clamp nut 4 and copper nut 5.Movable axis 6 is configured with Mounting hole, copper nut 5 is embedded into mounting hole, the outer wall of copper nut 5 is brought into close contact with mounting hole inwall, can also be in movable axis 6 sides open up waist-shaped hole, and are screwed (not shown), to prevent movable axis from being rotated with threaded.

Blade bearing 7 is connected by lock screw 8 with one end of movable axis 6 of adjusting means, another by adjusting adjusting means The dial 2 at end, movable axis 6 can stretch, and change the radius of bore hole.

The base of tool 7 uses cast member, and intensity is higher, can bear bigger load, improve production efficiency and precision.

The tooth of dial 2 makes Boring error away from for 0.25mm, making the variable quantities of each lattice of regulation scale be 0.005mm Reach ± 0.01mm.

Each parts such as right boring body 1, adjusting means, the base of tool 7 dimensional tolerance in processing is controlled in ± 0.01- 0.02mm, each part, which coordinates, makes boring cutter precision reach ± 0.01mm.

Staight shank path endoporus fine adjustment fine boring cutter provided by the utility model is described in detail above.Herein should Principle of the present utility model and embodiment are set forth with specific case, the explanation of above example is only intended to side Assistant solves core concept of the present utility model.It should be pointed out that for those skilled in the art, not departing from On the premise of the utility model principle, some improvement and modification can also be carried out to the utility model, these improve and modified Fall into the utility model scope of the claims.
