Description

Combined cutter

Technical Field

The utility model relates to a cutter, especially a gang tool.

Background

The steering column shell has various machining sizes, most of the steering column shell comprises arrangement sizes which are in a step-shaped state and are positioned on the same axis and have different apertures, the steering column shell also comprises chamfer sizes of an orifice end face and a connecting part of each hole, particularly the requirement on the precision of the diameter size tolerance of each hole is high, and meanwhile, the form and position tolerance of the machining part and the position size relative to a reference are also ensured. At present, particularly in the stage of developing and debugging new products, the general method is that multiple processes are processed in multiple steps, each process is divided into rough machining and finish machining, the rough machining of a general cutter mostly adopts a drill bit or an alloy reamer with an integral or welded blade, and the finish machining mostly adopts a fine-adjustable general boring cutter, so that the process beat, the cutter changing and feeding time and the cutter cost consumption expense are increased in the processing process, and the quality of processed products is difficult to ensure and is not suitable for batch production.

SUMMERY OF THE UTILITY MODEL

In order to solve the problem of bringing in the aspect of long, the cutter cost of processing beat time and the quality, satisfy the batch production demand, the utility model provides a non-standard gang tool of practical.

A gang tool, including rough machining cutter and finish machining cutter, its characterized in that: the rough machining cutter comprises a first cutter handle and a first cutter body, the first cutter body is distributed in a step shape from the top to the bottom, the diameters of the first cutter body are sequentially increased, and a first blade is arranged on the outer edge of a step surface; the finish machining cutter comprises a second cutter handle and a second cutter body, the second cutter body is distributed in a step shape from the top to the bottom, the diameter of the second cutter body is increased in sequence, and a second blade is arranged on the outer side of the outer edge of the step face.

In some embodiments, the first insert is a mechanically clamped cemented carbide insert.

In some embodiments, the first insert is fixedly clamped to the first cutter body by screws.

In some embodiments, the second blade is a PCD welding blade.

The beneficial effects of the utility model are that, when this nonstandard gang tool can increase substantially production efficiency, bigger reduction purchasing cost guarantees product geometric tolerances size, is the very effectual measure of better assurance product quality. The utility model discloses make the volume of scrapping greatly reduced of cutter, only need change the blade at every turn, and the cutter body can use for a long time, has practiced thrift the cost greatly, and economic benefits is showing and is improving.

Detailed Description

It should be noted that, in the present invention, the embodiments and features of the embodiments may be combined with each other without conflict.

The technical solution of the present invention will be described more clearly and completely with reference to the accompanying drawings, in which embodiments of the invention are shown and described. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

The combination tool of an embodiment of the present invention is described below with reference to fig. 1-2 in conjunction with an embodiment.

A gang tool, including rough machining cutter and finish machining cutter, its characterized in that: the rough machining cutter comprises a first cutter handle 2 and a first cutter body 1, the first cutter body 1 is distributed in a step shape from the top to the bottom, the diameters of the first cutter body 1 are sequentially increased, and a first blade 3 is arranged on the outer edge of a step surface; the finish machining cutter comprises a second cutter handle 5 and a second cutter body 4, the second cutter body is distributed in a step shape from the top to the bottom, the diameter of the second cutter body is increased in sequence, and a second blade 6 is arranged on the outer side of the outer edge of the step surface.

In some embodiments, the first blade 3 is a mechanically clamped cemented carbide blade.

In some embodiments, the first insert 3 is fixedly clamped to the first cutter body 1 by screws.

In some embodiments, the second blade 6 is a PCD welding blade.

When the tool is actually used, the first blade 3 is fixedly clamped on the first tool body 1 through screws, then the rough machining tool is installed on the first tool shank 2 through a spring sleeve, finally the rough machining tool is assembled on a main shaft of a machine tool to start rough machining, and after the rough machining is finished, the finish machining tool is used for finish machining, and the machining of the working procedure is finished. A plurality of kinds of cutters and tool handles processed in multiple holes in different processes are combined into a set of nonstandard combined cutter to be installed on one set of tool handles to be subjected to rough machining and finish machining, all processes such as end face milling, chamfering and reaming are completed at one time, the cutter installation mode adopts a screw machine clamping type blade clamping mode, a debugging worker only needs to replace the blade during tool changing, the operation is simple, the cutter body and the tool handles do not need to be replaced, the long-term use can be realized, and the cost is very low.

Compared with the prior art, the beneficial effects of the utility model are that, when this gang tool can increase substantially production efficiency, bigger reduction purchasing cost guarantees product geometric tolerances size, is the very effectual measure of better assurance product quality. The utility model discloses make the volume of scrapping greatly reduced of cutter, only need change the blade at every turn, and the cutter body can use for a long time, has practiced thrift the cost greatly, and economic benefits is showing and is improving.
