Description

Multi-section assembly tool structure

The invention relates to a multi-section assembly tool structure, in particular to a machining tool which can determine the length through assembly.

With the advancement of industrial processing technology, the application of automated multi-function processing tools (such as CNC lathes) to process objects such as cutting, drilling, etc., to replace the traditional processing of manpower control tools is becoming more and more popular. The processing type, and the various types of tools and various sizes of tools can be selectively switched to the characteristics of automatic multi-function processing tools in response to various processing operations.

However, most of the tools used in the conventional multi-function processing tool include a set of joints and a cutter head, and the main structure is an integrated structure, and the cutter set is joined to the processing tool by the assembly. In the groove, the tool head extending outside can process the object, but since the tool is a single type, it is fixed on the length of the tool, and thus it is desirable to use the same tool head but different When the length of the blade is to be processed, if the length of the boring cutter is to be extended to perform deeper hole cutting work, it is inevitable that only tool pieces of different lengths can be purchased, and the tool workpieces are often very expensive, such a It is undoubtedly a burden on production costs.

Therefore, the inventors of the present invention have conceived and designed a multi-section assembly tool structure in order to improve the lack of the prior art, thereby enhancing the industrial use and utilization.

In view of the above-mentioned shortcomings of the prior art, the present invention designs a multi-section tooling structure having patents such as novelty, advancement and industrial utilization, in order to overcome the difficulties of the prior art.

In order to achieve the above object, the technical means adopted by the present invention is to design a multi-section assembly tool structure, which comprises: a tool base corresponding to a rear end corresponding to a set of joints, which can be correspondingly connected to one a cutter groove is arranged in the groove of the multi-function machining tool, and an engagement groove is recessed inwardly at a front end of the tool base, and at least one lock hole is formed through a wall surface of at least one side of the engagement groove. The locking hole is connected to the set of connecting grooves; and a cutter member is provided with a machining blade at a front end, and a first connection extension extending at a rear end of the cutter member, outside the first connection extension The type is matched with the engaging groove and can be selectively inserted into the engaging groove, and then the rear end of the cutter member abuts against the front end of the tool base, so that a fastener can be inserted through the lock hole. It is fixed against the first connecting extension.

The multi-section assembly tool structure further includes at least one connecting seat, and a second connecting extending portion extending from a rear end is selectively disposed in the engaging groove, and the connecting seat is at a front end The recessed portion is provided with a fixed engaging groove, and the fixed engaging groove has an outer shape corresponding to the first connecting extending portion and the second connecting extending portion, and at least one string is respectively penetrated through the wall surface of at least one side of the fixed engaging groove The locking hole is further fixed from the serial locking hole through the locking member when the fixing engaging groove is sleeved on the second connecting extension of the first connecting extension or the other connecting seat.

Wherein the engaging groove is an annular groove.

The lock hole is a screw hole, and the lock is a screw lock.

Wherein the outer shape of the first connecting extension is matched to the engaging groove.

Wherein the shape of the second connecting extension is matched to the engaging groove.

Wherein the outer shape of the fixed engagement groove is matched to the first connection extension.

Wherein the outer shape of the fixed engagement groove is matched to the second connection extension.

The multi-section tool-type tool structure of the invention is designed to divide the traditional one-piece tool into two parts, a tool base and a tool piece, and is selectively bridged with a connecting seat therebetween. Or a plurality of connectors can be connected in series according to the change of the length, so as to provide a function of increasing or decreasing the connector to change the overall length according to the use requirement, and eliminating the need to separately use the tools of different lengths in the prior art. The problem of excessive cost burden is caused by the purchase, and the connection between the tool base, the tool member and the connecting seat is matched through the wall surface, so that the stabilizing effect after the assembly is stabilized to avoid the cutting of the tool. Unexpected sloshing and the like.

In order to make the above-mentioned objects, technical features, and gains after actual implementation more obvious, a more detailed description will be given below with reference to the corresponding drawings in the preferred embodiments.
