Detailed Description

The utility model is further illustrated and described below in conjunction with the specific embodiments and the accompanying drawings:

Example 1

Referring to fig. 1 and 2, an assembled machine tool cutter structure comprises a cutter handle 10 and a blade 20, wherein the cutter handle 10 and the blade 20 are detachably connected, one end of the cutter handle 10 is fixedly connected with a machine tool spindle, the other end of the cutter handle 10 is provided with a clamping groove 11, the blade 20 is fixed inside the clamping groove 11 through a fixing screw 30, one end of the blade 20 protrudes out of one side of the clamping groove 11, a convex rib 12 is arranged at the bottom of the clamping groove 11, the convex rib 12 is arranged around the fixing screw 30, a groove 21 is arranged below the blade 20, the groove 21 and the convex rib 12 are correspondingly formed, and the blade 20 is clamped with the convex rib 12 through the groove 21.

The blade 20 has a regular triangle structure, and the triangle of the blade 20 is correspondingly provided with the cutting edge 22, so that the cutting edge 22 can be used for processing by adjusting the orientation of the blade 20.

When the cutter handle 10 and the cutter handle 10 are fixedly connected, the groove 21 below the cutter blade 20 is aligned with the convex rib 12 on the clamping groove 11 of the cutter handle 10, so that the cutter blade 20 can be primarily limited in the clamping groove 11, the cutter blade 20 and the cutter handle 10 are fixedly connected by the aid of the fixing bolts, the convex rib 12 is arranged around the fixing bolts, the cutter blade 20 can be limited and fixed in multiple directions, deflection of the cutter blade 20 in the machining process is avoided, machining precision is influenced, and meanwhile, the cutter blade 20 is better and different machining types are adapted conveniently.

In the above scheme, the vertical section of protruding muscle 12 is isosceles trapezoid structure, and recess 21 and protruding muscle 12 shape looks adaptation, and when making things convenient for blade 20 to assemble draw-in groove 11 inside, recess 21 plays the guide effect with protruding muscle 12, because isosceles trapezoid is the structure of upper narrow lower wide to on recess 21 carries out the counterpoint with protruding muscle 12, can play the guide effect along the inclined plane of protruding muscle 12 both sides, thereby make things convenient for the counterpoint when people install.

The draw-in groove 11 one side is the opening form, and draw-in groove 11 is extended through the opening part to blade 20 one end to be convenient for blade 20 extends handle of a knife 10 and processes the work piece, avoids handle of a knife 10 to cause the interference when processing, and draw-in groove 11 is loudspeaker form structure towards the opening part for blade 20 is when processing, can the work piece contact, thereby has the effort to promote blade 20 towards the inside draw-in groove 11, and draw-in groove 11 opening part is loudspeaker form structure and is favorable to the screens of blade 20.
