Abstract

The utility model relates to a milling cutter which comprises a cutter shank, a cutter body, and cutter edges, wherein the cutter body is shaped as a round platform, one end of the cutter body is connected with the cutter shank, four inclines and corresponding grooves are formed on the end face at the other end part along the radial direction of the circumference at 90 degrees intervals, a central groove is formed at the center of the end face of the cutter body, the four inclines are respectively provided with an edge, and each edge comprises an upper end face positioned at the end face of the cutter body and a side end face extending to the side of the cutter body along the end face of the cutter body. The side end face of each edge and the radial direction of the end face of the cutter body angle an angle Alpha. The upper end face of each edge and the axial direction of the cutter body angle an angle Beta of 70 degrees, and the upper end face of each edge and the radial direction of the end face of the cutter body angle an angle Gamma. The utility model ensures the size precision and the surface smooth finish, shortens the cutting time, especially the clamping complexity and the clamping time, and improves the production efficiency.

Description

A kind of milling cutter

Technical field

The utility model relates to a kind of milling cutter.

Background technology

BMW lattice bearing is the hand of engineering machinery road roller equipment, form one of vital part of road roller, road roller part carrier annual production more than 2000 covers, it is 70 ° inclined-plane that a boss is arranged in process, because the bigger on the whole and shape of part is comparatively complicated, moreover the thickness of part is thinner relatively, processing the less inclined-plane of area on the part like this, the big planar central in present position, inclined-plane position in addition, use plain-milling machine, the not enough or very difficult clamping of angle of machine tool chief axis size just occurs, work in-process is processed in the heart, if oversize when processing milli with the mode of scanning, position and angle are had higher requirement to the processing economic benefit of this product.

Summary of the invention

The purpose of this utility model is a kind of milling cutter of design, when guaranteeing dimensional accuracy and surface smoothness, shortens cutting time, especially clamping complexity and clamping time, enhances productivity.

For achieving the above object, the technical solution of the utility model is,

A kind of milling cutter, it comprises, handle of a knife; Cutter hub is round table-like, and the one end is connected in handle of a knife, and the other end end face forms four inclined-planes and corresponding grooves along circumference spaced radial 90 degree, and cutter hub end face central authorities form central recess; Establish blade respectively on four inclined-planes, this blade comprises upper surface that is positioned at the cutter hub end face and the side end face that extends to the cutter hub side along the cutter hub end face.

Further, described blade side end face and cutter hub end face radial axle α at angle.

Again, described blade upper surface axially becomes 70 degree angle β with cutter hub.

In addition, described blade upper surface and cutter hub end face radial axle γ at angle.

Described cutter hub and handle of a knife are welded into a whole.

The beneficial effects of the utility model

The utility model is for shortening the cutting time, avoid work in-process to use the method for stepping multitool excision material in the heart, can use the method for strickling by the design cutter, once can or twice feed just can remove surplus, and can protect dimensional accuracy and surface smoothness, shortened the cutting time greatly, especially clamping complexity and clamping time.Shortened to 3 minute 50 second by original 25 minutes and 10 seconds process time.

Description of drawings

Fig. 1 is the structural representation of the utility model one embodiment;

Fig. 2 is the side view of Fig. 1;

Fig. 3 is the vertical view of Fig. 1.

The specific embodiment

Referring to Fig. 1～Fig. 3, a kind of milling cutter of the present utility model, it comprises, handle of a knife 1, cutter hub 2; Wherein, cutter hub 2 is round table-like, and the one end is connected in handle of a knife 1, and the other end end face 21 forms four inclined-planes 22 and corresponding grooves 23 along circumference spaced radial 90 degree, and cutter hub end face 21 central authorities form central recess 24; Establish blade 3 respectively on four inclined-planes 22, this blade 3 comprises upper surface 31 that is positioned at cutter hub end face 21 and the side end face 32 that extends to cutter hub side 25 along cutter hub end face 21.

Described blade 3 side end faces 32 and cutter hub end face 21 radial axles are α at angle; Described blade upper surface 31 axially becomes 70 degree angle β with cutter hub 2; Described blade upper surface 31 and cutter hub end face 21 radial axles are γ at angle.

Described cutter hub 2 is welded into a whole with handle of a knife 1.

The utility model is by the architecture advances of cutter hub, makes cutter can use the method for strickling, once can or twice feed just can remove surplus, and can protect dimensional accuracy and surface smoothness, shortened the cutting time greatly.
