Background

A lathe is a machining apparatus which occupies the largest amount of equipment in machining, and a turning tool, which is a tool having a cutting portion for turning, is often used in lathe machining. Turning tools are one of the most widely used tools in cutting machining.

The traditional turning tool is directly arranged on a tool rest and is compressed by a tool pressing screw after adjustment and positioning, but when heavy cutting with large cutting force is carried out, the cutting resistance can cause the tool to generate displacement, and the cutting quality can be influenced or even accidents can be caused under the condition.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cutter closing device can tightly fix the cutter on the knife rest, makes the cutter when bearing great cutting force, and the cutter can not remove, can keep in the exact cutting position all the time.

The utility model provides a cutter closing device, including knife rest, clamp plate and cutter, be equipped with the cutter mounting groove on the knife rest, the cutter sets up in the cutter mounting groove, be equipped with housing screw on the knife rest, knife rest one side sets up the clamp plate, the knife rest with the connection can be dismantled to the clamp plate.

Further, the compression screw is provided in plurality. The tool holder and the tool are pressed tightly by a pressing screw. Preferably 2-4. The compression screws are uniformly distributed, so that the fastening effect is better.

Further, the central axis of the compression screw is perpendicular to the upper surface of the cutter. The compression screw can better play a role in compressing the tool rest and the tool.

Further, the tool rest is connected with the pressure plate through a detachable screw. The detachable screw is screwed down to tightly press the pressing plate and the tool rest, so that the tool is tightly pressed on the tool rest, and the tool cannot move and can be always kept at a correct cutting position when the cutting depth is large or large cutting force is borne by the tool.

Furthermore, the detachable screws are provided with at least two detachable screws and are respectively an upper detachable screw and a lower detachable screw, and the upper detachable screw and the lower detachable screw are respectively arranged on two sides of the cutter mounting groove. The cutter is more stable on the cutter frame.

Furthermore, the upper detachable screws are provided with two, the lower detachable screws are provided with two, the upper detachable screws and the lower detachable screws are respectively arranged at four corners of the pressing plate, and the tool rest is provided with threads corresponding to the tool rest. By means of the arrangement, the pressing plate is fastened with the tool rest, and therefore the tool is stable on the tool rest.

Furthermore, a fastening screw is arranged on the pressure plate corresponding to the position of the cutter in the cutter mounting groove. By tightening the fastening screw, the tool is compressed in the tool-mounting slot, thereby making the tool more stable on the tool holder.

Further, the central axis of the fastening screw is perpendicular to the upper surface of the cutter. The effect of pressing the pressing plate and the cutter can be better achieved.

Further, the fastening screw is provided in plurality. Preferably set up threely, three fastening screw equipartition sets up, and fastening effect is better.

Compared with the prior art, the utility model discloses following effect has:

the utility model discloses on the basis that housing screw compresses tightly the cutter, compress tightly clamp plate and knife rest through fastening screw and detachable screw to tightly fix the cutter on the knife rest, make the cutter when depth of cut is great or bear great cutting force, the cutter can not remove, can keep in the exact cutting position all the time.
