The invention aims to solve the problems that the milling cutter head cannot be designed by self, the flexibility is poor, the cutter head needs to be integrally replaced when being damaged, and the use cost is improved.

The invention achieves the purpose through the following technical scheme, and the reverse milling cutter structure comprises a cutter handle connected to the driving end of a machine tool and a cutter head used for machining a mold, wherein a plurality of detachable blade sets are annularly distributed on the outer wall of the cutter head, each detachable blade set comprises a blade support frame welded on the side wall of the cutter head and a milling blade attached to the blade support frame, and the milling blade is fixed through a mounting screw.

Preferably, the side wall of the blade supporting frame is provided with an inverted L-shaped groove, the milling blade is attached inside the groove, and the contact surfaces of the milling blade and the blade supporting frame are smooth surfaces.

Preferably, the connecting end of the handle and the tool bit is provided with a square joint, the center of the tool bit penetrates through a square hole, and the tool bit is fixed on the square joint of the handle through the square hole.

Preferably, the handle of a knife is hollow structure, inside cartridge screw post, and the screw post includes the pole seat and the body of rod, and wherein the inside that the pole seat inserted the handle of a knife is fixed by the spacing bolt of handle of a knife lateral wall installation, and the outer wall installation limit nut of the body of rod restricts the tool bit and removes.

Preferably, the limiting nut is fixed with the rod body through a fixing screw arranged on the side face.

Compared with the prior art, the invention has the beneficial effects that:

1. through with milling cutter piece movable mounting on the cutter head, carry out the side milling processing, consequently milling cutter piece can select some tool bits to scrap in the selection, and the better blade of cutting edge has improved waste utilization, practices thrift milling cutter's cost, and milling cutter piece can be dismantled also convenience of customers and when processing different moulds, changes the type of blade by oneself, adapts to different moulds, makes this milling cutter use more nimble.

2. Through with tool bit movable assembly to the handle of a knife, make things convenient for the change of tool bit and user's design by oneself, the tool bit is earlier through the quad slit suit on the square joint of handle of a knife, send relative rotation with the handle of a knife when preventing that the tool bit from rotating, pass the tool bit and to the built-in screw rod post of packing into of handle of a knife, the rod seat end of screw rod post is fixed through the spacing bolt of handle of a knife lateral wall, the body of rod end is through cup jointing limit nut and is cliied the tool bit, prevent that the tool bit from droing and shifting up in.

3. Prevent that the body of rod of limit nut and screw rod post from taking place to rotate through nailing set screw on limit nut, can prevent that limit nut from rotating from the body of rod and droing when milling cutter reverse work, use safelyr.

Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Example 1

Referring to fig. 1 and 3, a reverse milling cutter structure includes a handle 1 connected to a driving end of a machine tool and a cutter head 2 for processing a mold, a plurality of detachable blade sets 3 are annularly distributed on an outer wall of the cutter head 2, each detachable blade set 3 includes a blade support 11 welded on a side wall of the cutter head 2 and a milling blade 12 attached to the blade support 11, the milling blade 12 is fixed by a mounting screw 13, a groove with an inverted L-shaped structure is formed in a side wall of the blade support 11, the milling blade 12 is attached to the inside of the groove, contact surfaces of the milling blade 12 and the blade support 11 are both smooth surfaces, the detachable blade set 3 on the cutter head 2 is composed of the blade support 11 attached to the milling blade 12, the milling blade 12 can be selected according to requirements of the processing mold, and since the cutter head 2 is used for side milling, the milling blade 12 can also be selected to have a complete cutting edge, the milling cutter blade 12 with the scrapped cutter tip utilizes the waste, the processing cost is saved, the contact surfaces of the milling cutter blade 12 and the blade supporting frame 11 are both processed into smooth surfaces, thus the milling cutter blade 12 can be prevented from shaking caused by gaps when the milling cutter blade 12 is mounted, and the milling cutter blade 12 is fixed by mounting 13 screws to form a complete cutter head 2.

Example 2

According to the drawings of fig. 2 and 4, a square joint 7 is arranged at the connecting end of a knife handle 1 and a knife head 2, a square hole 14 is arranged in the center of the knife head 2 in a penetrating mode, the knife head 2 is fixed on the square joint 7 of the knife handle 1 through the square hole 14, the square hole 14 is clamped on the square joint 7, when the knife head 2 rotates, the knife head 2 and the knife handle 1 can be prevented from rotating relatively to affect work, the knife handle 1 is of a hollow structure, a screw column 6 is inserted inside the knife handle 1, the screw column 6 comprises a rod seat 8 and a rod body 9, wherein the rod seat 8 is inserted inside the knife handle 1 and is fixed through a limiting bolt 4 arranged on the side wall of the knife handle 1, a limiting nut 5 is arranged on the outer wall of the rod body 9 to limit the movement of the knife head 2, the knife head 2 is also of a detachable structure, the screw column 6 is inserted into the knife handle 1 firstly, the rod seat 8 of the screw column, and then the limiting nut 4 is screwed on the rod body 9 extending out of the knife handle 1 to clamp the knife head 2, so that the knife head 2 cannot move up and down and cannot fall off in the rotating process, and the use is safer.

Example 3

Stop nut 5 is fixed with the body of rod 9 by side-mounted's set screw 10, and some milling cutters need reverse rotation processing, because stop nut 5 is twisted clockwise on the body of rod 9, twists when the tool bit 2 drops very easily to the rotation, can prevent that stop nut 5 from dropping from the body of rod 9 through nailing set screw 10 to stop nut 5's side.
