Description

Spacing type taper reamer

Technical Field

The utility model relates to a spacing formula tapering reamer belongs to the technical field of tapering reamer.

Background

The taper reamer is used for reaming the positioning pin holes with the same taper. The reamer is used for reaming drilled (or reamed) holes on workpieces, mainly for improving the machining precision of the holes and reducing the roughness of the surfaces of the holes, and is a tool for finish machining and semi-finish machining of the holes.

However, when some parts with deep holes and tapered sealing surfaces need to be machined at the bottoms of the deep holes, due to the strict size requirement of the conical surface section, for non-numerical control machines, the feeding amount is difficult to accurately control by using a common tapered reamer, the tool setting process is complicated, and the machining efficiency is extremely low.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a spacing formula tapering reamer has the effect of accurate adjustment tapering reamer feed volume.

In order to realize the purpose, the utility model discloses a technical scheme is:

the utility model provides a spacing formula tapering reamer, includes the cutter body, the one end of cutter body is the tool bit, the centre of cutter body sets up spacing platform, spacing bench is provided with the stopper that can adjust at spacing bench.

The utility model discloses technical scheme's further improvement lies in: the surface of the limiting table is provided with threads, and the limiting block comprises a limiting nut which can rotate on the limiting table.

The utility model discloses technical scheme's further improvement lies in: the limiting block further comprises a locking nut which can rotate on the limiting table and is used for fixing the limiting nut.

Since the technical scheme is used, the utility model discloses the technological effect who gains has:

the product of the utility model is simple in structure, easy to adjust and install, and strong in specificity. Through adjusting stop nut, adaptation part that can be better, accurate control to solve the low conical surface size problem that needs processing sealed conical surface part in deep hole.

When an ordinary reamer is machined, the feeding amount cannot be accurately controlled, so that the size of a conical surface to be machined cannot be accurately controlled. And this patent application can set for the size of feeding through adjusting limit nut, and limit nut removes on spacing bench, adjusts the size of feeding, belongs to infinitely variable control, can the accurate control volume of feeding to the assurance is treated the machining dimension.

Detailed Description

The present invention will be described in further detail with reference to the following drawings and specific embodiments:

the utility model discloses a limiting taper reamer, which is shown by referring to fig. 1 and fig. 2 and comprises a cutter body 1, wherein the cutter body 1 is cylindrical, a cutter head 2 is fixedly arranged at one end of the cutter body 1, the other end of the cutter body 1 is sleeved with a cutter handle sleeve, a limiting table 3 is fixedly arranged at the middle position of the cutter body 1, the limiting table 3 is a circular table concentrically arranged with the cutter body 1, a thread is arranged on the surface of the limiting table 3 along the circumference of the limiting table 3, and a limiting nut 4 and a locking nut 5 are connected through the thread; and the limiting nut 4 is arranged between the tool bit 2 and the locking nut 5, and the limiting nut 4 is fixed by screwing the locking nut 5.

Referring to fig. 3 and 4, in the workpiece with the conical surface to be machined, a is the conical surface to be machined, the conical surface to be machined has a sealing function, the dimension b to be machined has strict dimensional requirements, and when a common reamer is machined, the feeding amount cannot be accurately controlled, so that the dimension b to be machined cannot be accurately controlled. A required feeding size a is calculated by a limiting type taper reamer through a known size b to be machined, then a limiting nut 4 is adjusted to set the feeding size a, and a cutter head 2 corresponding to the size b to be machined is replaced for machining, so that the size b to be machined is guaranteed.

The embodiments of the present invention are preferred embodiments of the present invention, and the scope of the present invention is not limited by these embodiments, so: all equivalent changes made according to the structure, shape, principle and the like of the invention are covered by the protection scope of the invention.
