Description

A kind of long-armed cutterhead of CNC

Technical field

The utility model belongs to CNC process tool field, specifically designs a kind of long-armed cutterhead of CNC.

Background technique

In existing numerical control CNC processing, the bloom of converted products is commonly used to by the dise knife that cutterhead, knife handle and knife grain form Face.The design of cutterhead directly determines the performance of dise knife processing, when bigger due to common cutter diameter, the bigger line of cutterhead self gravity Speed is smaller, is difficult to cut the highlight surface of good luster in CNC spinning process, and it is uneven and black to be also easy to produce vibration knife mark, side The flaws such as line.Therefore, it is necessary to design a kind of long-armed cutterhead of small and big linear velocity CNC of being self-possessed.

Utility model content

It is difficult to the shortcomings that taking into account self weight and linear velocity with the cutterhead of processing highlight surface for existing CNC, the utility model It is designed to provide a kind of long-armed cutterhead of CNC, structure is simple, ingenious in design, guarantee while there capable of be small self weight Big linear velocity, firm and durable, so that it is guaranteed that the effect of highlight surface processing.

To achieve the above object, technical solution adopted in the utility model is as follows:

A kind of long-armed cutterhead of CNC, including knife handle set, long-armed knife rest and fixed block:

The knife handle set is cylinder, and the top surface of knife handle set is equipped with fixation hole, and knife handle is plugged in fixation hole and knife handle Set is fixedly connected；

The long-armed knife rest is strip, and long-armed knife rest is set on the bottom surface of knife handle set, and knife is stretched out at the both ends of long-armed knife rest The bottom surface of sleeve and it is respectively equipped with centrosymmetric knife grain fixed arm, knife grain fixed arm is equipped with knife grain fixation hole, and knife grain is fixed Hole is used for fixing cutter grain；

The fixed block is Irregular hexahedron, and fixed block is set to knife handle and covers between long-armed knife rest, the side of fixed block Shape matches with the side that knife handle covers and is fixedly connected with the side of knife handle set, the bottom shape of fixed block and long-armed knife rest Top surface shape matches and is fixedly connected with the top surface of long-armed knife rest.

Further, it is bolted to connection between the fixed block and long-armed knife rest.

Further, the number of the fixed block is two.

Further, it is fixedly connected by welding between the fixation hole and knife handle of the knife handle set, guarantees knife handle high speed rotation When can securely drive knife handle set rotation.

Further, it is fixedly connected by welding between the long-armed knife rest and the bottom surface of knife handle set, guarantees knife handle set high speed Long-armed knife rest can be securely driven to rotate when rotation.

The utility model has the following beneficial effects:

1, it is covered by knife handle and is fixedly connected with the long-armed knife rest of strip, it is long when knife handle drives knife handle set high speed rotation Fixed knife grain has biggish linear velocity compared to knife handle set on the knife grain fixed arm at arm knife rest both ends, can rapidly and efficiently will be high Smooth surface cutting forming guarantees the finish of highlight surface.

2, by the way that fixed block is arranged between knife handle set and long-armed knife rest, ensure that in high-speed cutting knife handle set with it is long-armed Being fixedly secured between knife rest, and then ensure the firm and durable of long-armed cutterhead entirety；The knife grain fixed arm of long-armed knife rest is symmetrically set The uniform force for setting long-armed cutterhead all directions when also ensuring High-speed machining avoids local pressure unevenness that long-armed knife rest is caused to deform And then highlight surface cutting effect is influenced, further ensure the firm and durable of the long-armed cutterhead of CNC of the utility model.

Detailed description of the invention

Fig. 2 is the top view of the utility model.

Specific embodiment

Explanation is further explained to the application with reference to the accompanying drawings and examples.

Embodiment

The technical scheme adopted by the utility model is

A kind of long-armed cutterhead of CNC, as depicted in figs. 1 and 2, including knife handle set 1, long-armed knife rest 4 and fixed block 3:

Knife handle set 1 is cylinder, and the top surface of knife handle set 1 is equipped with fixation hole 2, knife handle be plugged in fixation hole 2 with Knife handle set 1 is fixedly connected；The long-armed knife rest 4 is strip, and long-armed knife rest 4 is set on the bottom surface of knife handle set 1, long-armed knife rest 4 Both ends stretch out knife handle set 1 bottom surface and be respectively equipped with centrosymmetric knife grain fixed arm 5, knife grain fixed arm 5 be equipped with knife grain Fixation hole 6, knife grain fixation hole 6 are used for fixing cutter grain, are screwed between knife grain and knife grain fixation hole 6；The fixed block 3 is Irregular hexahedron, fixed block 3 are set between knife handle set 1 and long-armed knife rest 4, the side of side view and the knife handle set 1 of fixed block 3 Face matches and is fixedly connected with the side of knife handle set 1, the top surface shape phase of the bottom shape of fixed block 3 and long-armed knife rest 4 Match and is fixedly connected with the top surface of long-armed knife rest 4.Further, fixed by bolt 7 between the fixed block 3 and long-armed knife rest 4 Connection.Further, the number of the fixed block 3 is two.Further, lead between the fixation hole 2 and knife handle of the knife handle set 1 It crosses and connection is welded and fixed, guarantee securely drive 1 rotation of knife handle set when knife handle high speed rotation.Further, the long-armed knife It is fixedly connected by welding between frame 4 and the bottom surface of knife handle set 1, guarantees securely drive long-armed knife when knife handle covers 1 high speed rotation Frame 4 rotates.

When operator uses the present apparatus, knife handle is fixedly connected with knife handle set 1, then knife is installed on knife grain fixed arm 5 Grain is integrally formed the long-armed dise knife of CNC, then long-armed knife rest 4 is guaranteed knife handle frame by 7 fixation of bolt on fixed block 3 Long-armed knife rest 4 will not be covered on 1 from knife handle and be fallen off when 1 high speed rotation, enhance the firm and durable of long-armed dise knife.Simultaneously because long-armed 5 center symmetric setting of knife grain fixed arm at 4 both ends of knife rest, in the cutting of highlight surface, long-armed 4 all directions dynamic stress of knife rest is equal It is even, avoid the long-armed deformation of knife rest 4 to make knife grain positional shift scratching products surface influence finish.

Utility model device is easy to use, structure is reliable, production is simple, be difficult to combine in more existing dise knife it is small from The shortcomings that great linear velocity and firm and durable, has compared with much progress: passing through the fixed company of long-armed knife rest 4 of knife handle set 1 and strip It connects, when knife handle drives knife handle to cover 1 high speed rotation, fixed knife grain compares knife handle on the knife grain fixed arm 5 at long-armed 4 both ends of knife rest Set 1 has biggish linear velocity, can guarantee the finish of highlight surface rapidly and efficiently by highlight surface cutting forming.Furthermore in knife Fixed block 3 is set between sleeve 1 and long-armed knife rest 4, ensure that secured between knife handle set 1 and long-armed knife rest 4 in high-speed cutting It is fixed, and then ensure the firm and durable of long-armed cutterhead entirety；The knife grain fixed arm 5 of long-armed knife rest 4 is symmetrical arranged and also ensures The uniform force of long-armed cutterhead all directions when High-speed machining avoids local pressure unevenness that long-armed knife rest 4 is caused to deform and then influence Highlight surface cutting effect further ensures the firm and durable of the long-armed cutterhead of CNC of the utility model.
