Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. 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.

Referring to fig. 1-4, the present invention provides a technical solution: the utility model provides an alloy milling cutter for milling machine, includes main part 1, and main part 1 includes handle of a

knife

12, and 12 outside movable mounting of handle of a knife have last antislip strip 21 and antislip strip 22 down, go up antislip strip 21 and antislip strip 22 circumference down and set up in the handle of a knife 12 outside, and main part 1 includes tool bit 11, and tool bit 11 is fixed in the one end of handle of a knife 12.

The thickness and the length of going up antislip strip 21 and antislip strip 22 down equal, and the distance that 11 one end of tool bit was kept away from to lower antislip strip 22 and handle of a knife 12 is less than the distance that 11 one end of tool bit was kept away from to last antislip strip 21 and handle of a knife 12, goes up antislip strip 21 and lower antislip strip 22 interval and sets up in the handle of a knife 12 outside.

The inside annular of having seted up of main part 1 separates the chamber 31, it all wears to locate the annular and separates the chamber 31 inside with one side that lower antislip strip 22 is close to 1 centre of a circle department of main part 21 to go up antislip strip 21, one side that lower antislip strip 22 is close to 1 centre of a circle department of main part all is provided with limit baffle 32, limit baffle 32 installs inside the chamber 31 is separated to the annular, the annular separates the inside circumference of chamber 31 and installs a plurality of stock 34, the number of stock 34 equals with last antislip strip 21 and lower antislip strip 22 number sum, it all is connected with spring 33 with between the corresponding stock 34 with lower antislip strip 22 to go up antislip strip 21.

The working principle is as follows: when the milling cutter is used with the clamping device, the holder 12 of the main body 1 is clamped by the clamping device, at the moment, under the action of the upper anti-slip strips 21 and the lower anti-slip strips 22, when the clamping device drives the holder 12 to rotate, large friction force is generated between the holder and the upper anti-slip strips 21 and between the holder and the lower anti-slip strips 22, the upper anti-slip strips 21 and the lower anti-slip strips 22 are arranged in a staggered mode and in an interval mode, gaps exist between the upper anti-slip strips 21 and the lower anti-slip strips 22, the boundaries between the upper anti-slip strips and the lower anti-slip strips are in direct contact with the inside of the clamping device, the friction coefficient is high, and under the action of the limiting baffle 32, the upper anti-slip strips 21 and the lower anti-slip strips 22 cannot be completely pushed into the annular partition cavity 31 due to overlarge clamping force of the clamping device.

And because of last antislip strip 21 and lower antislip strip 22 lead to the clearance that handle of a knife 12 and centre gripping equipment spare produced, when the piece that produces in the cutting process got into in this clearance, when the piece passes through the neutral between the antislip strip 21, can be blockked by lower antislip strip 22 directly, can effectively prevent the piece that produces in the cutting process from getting into inside the centre gripping equipment from this clearance through the mode that last antislip strip 21 and lower antislip strip 22 interval set up, guarantee the inside clean and tidy degree of centre gripping equipment, avoid it to lead to the function limited because of blocking the piece.

When the clamping device drives the milling cutter to rotate at a high speed, under the action of centrifugal force, the upper anti-slip strip 21 and the lower anti-slip strip 22 are influenced by the centrifugal force, certain pressure is generated on the inner wall of the clamping device, the friction force between the clamping device and the main body 1 is increased due to the fact that the friction force is in direct proportion to the friction coefficient and the pressure in the vertical direction of the contact surface, and therefore when the milling cutter rotates at a high speed, the friction force generated between the milling cutter and the clamping device is larger, and the milling cutter is prevented from sliding to a greater extent.

Through the device, the milling cutter can be efficiently prevented from skidding, so that the phenomenon of skidding between the cutter handle and the clamping equipment due to overlarge acting force can be avoided when the milling cutter is subjected to violent cutting, rapid feeding or overlarge cutting force, and the cutting effect can reach an ideal state.
