Description

Quick clamping device for cutter

Technical Field

The utility model relates to the technical field of tool clamping of numerically controlled lathes, in particular to a tool rapid clamping device.

Background

In the field of numerical control lathe machining, a clamping technology of a cutter is one of key factors for improving production efficiency and machining quality, and quick replacement of the cutter is important for improving production efficiency and machining quality. The traditional numerical control lathe tool clamping mode has a plurality of inconveniences, such as low machining efficiency, in the machining process, if the tool needs to be replaced, the tool needs to be re-aligned, which is time-consuming, the consistency of the sizes of parts cannot be ensured, and sometimes even the machine tool needs to be replaced for secondary clamping and machining. The tool change time is long, and most of the machine tool time is not used for producing parts in a machining production workshop, but is consumed in equipment failure, workpiece and tool change and equipment maintenance. The time for tool change and adjustment is often long, resulting in low machine tool utilization. The time for replacing the cutter is long, the cutter is required to be used, and damage to the cutter or reduction of machining precision are easily caused in the replacing process. In addition, frequent tool replacement also increases the labor intensity of workers, affecting production efficiency. Therefore, developing a clamping device capable of rapidly replacing a cutter has important significance for improving production efficiency and processing quality.

Disclosure of utility model

The utility model aims to provide a quick clamping device for a cutter of a numerical control lathe, which aims to solve the problems of inconvenient replacement and low efficiency of the cutter of the numerical control lathe in the prior art.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

The quick clamping device for the cutter comprises a connecting column, a rotary cutter rest and a cutter holder, wherein the connecting column penetrates through the center of the rotary cutter rest, the rotary cutter rest can rotate 90 degrees around the center line of the connecting column, the rotary cutter rest is provided with four vertical faces, each vertical face is provided with a cutter holder positioning groove, and a raised cutter holder positioning block is arranged on the cutter holder and is matched with the cutter holder positioning groove.

Further, the upper side and the lower side of the rotary knife rest are respectively provided with a knife rest upper seat and a knife rest base, and the knife rest upper seat is provided with a protective cover for protecting the connecting column.

The bottom of the tool rest base is provided with a supporting seat, and one side of the supporting seat is provided with a driving assembly.

The vertical surface of the rotating tool rest is higher than the tool rest, and the tool rest can be adjusted along the upper and lower positions of the tool rest positioning groove.

The axis of the tool apron is provided with a clamping hole.

Compared with the prior art, the utility model has the advantages that the rotary knife rest is designed, the knife rest is arranged on the vertical face part of the rotary knife rest, and the grinding straight shank drill bit and the grinding milling cutter are arranged on the knife rest so as to realize the clamping of multiple knives. The rotary tool rest can rotate 90 degrees around the central line of the connecting column so as to realize quick replacement of different tools. A mounting assembly is designed for securing a straight shank drill bit and a milling cutter to a rotating tool holder to ensure stability of the cutter during machining. The utility model can be used for quickly replacing the cutter without using any tool, and the design of the utility model allows the cutter to be quickly replaced without using any tool, thereby improving the working efficiency. The utility model has the advantages of simple design structure, convenient operation and good practicability, and reduces the labor intensity of workers.
