Description
Technical field
The present invention relates to the field of metal processing, especially a kind of machine tooling scrap clamp device.
Background technique
Present machine tooling becomes very universal, and mostly uses numerically-controlled machine tool to be processed greatly, and numerically-controlled machine tool has
Precision it is fast at high speed the advantages that, during processing, under the rotation of process tool, work piece can generate a large amount of useless
Bits.
When processing to automatic steel steel grade, scrap can become powder, Bu Huihua under high-frequency vibration
Hurt workpiece outer surface.But when being processed to toughness material, using hilted broadsword carry out cutting or turn hole when it is useless
Bits can become band, and as the increase of process time is increasingly longer, increases and scratch machined good piece surface
Possibility be easy to cause scrapping for workpiece.And it is also possible that band-like scrap is wound on process tool, shadow is caused to processing
It rings.
So need one can by band-like scrap to recycling device, recyclable device recycling when firstly the need of will
Band-like scrap, which is given to fix, can just take other means by band-like scrap to recycling.Way of recycling can have stretching recycling also to have rotation
Turn winding recycling, but rotation winding recycling is just needed for band-like scrap to be fixed in shaft.
Summary of the invention
In view of the above drawbacks of the prior art, it is an object of the invention to provide a kind of fastenings of machine tooling scrap item to fill
It sets, band-like scrap can be fixed in the shaft of rotation winding recyclable device, be given band-like scrap by rotating to realize

Corresponding band outlet 51；The inner peripheral surface of tape drum 5 is equipped with the strip gab of annular；
One end of restraint zone 2 passes through and drive after several circles of tape drum 5 from another band outlet 51 from a band outlet 51
Dynamic motor 3 connects, and the other end of restraint zone 2 is connect with recyclable device 4；The width at the middle part of restraint zone 2 becomes narrow gradually；Restraint zone
The width at 2 middle part is no more than the width of strip gab；The width of 2 head of restraint zone and tail portion is greater than the width of strip gab.
Fastening tape scrap may be implemented by flexible fixation by using restraint zone 2, by 5 inner peripheral surface of tape drum
Equipped with strip gab, while constriction will be set as in the middle part of restraint zone, thus realize need 2 shape scrap of restraint zone when
It waits, pulls restraint zone 2 that can realize that restraint zone 2 is wound into the shaft 10 for recycling band-like scrap from disengaging in tape drum 5.Simultaneously
Setting recyclable device 4 may be implemented when not needing fastening, and restraint zone can not be in the shaft of the band-like scrap of winding recycling
10。
In the present embodiment, recyclable device 4 includes wind spring 41, reel 42 and U-shaped seat 43；U-shaped seat 43 is mounted on mounting base 1
On；42 housing of reel is in U-shaped seat 43；The both ends of wind spring 41 are connect with U-shaped seat 43 and wind spring 41 respectively；Restraint zone and reel 42
It is affixed.
The function that automatic recycling restraint zone is realized by wind spring 41, conveniently reuses.

10。
In the present embodiment, recyclable device 4 is servo motor 9；One end of restraint zone 2 is connect with servo motor 9.
Quickly restraint zone can be recycled by servo motor 9, and can control restraint zone during recycling
Tightness realization is at the uniform velocity recycled, and the case where restraint zone and strip gab are stuck in recycling can be effectively reduced.
In the present embodiment, restraint zone 2 includes internal layer 21, outer layer 22 and structure sheaf；Structure sheaf is located at internal layer 21 and outer layer
Between 22；Structure sheaf includes several thin bars 23；Several thin bars 23 are uniformly wrapped up by internal layer 21 and outer layer 22；Several thin bars 23
Both ends are flushed with two sides of restraint zone 2 respectively.
Setting structure layer and the both ends of thin bar 23 is made to flush and can have with two sides of restraint zone 2 respectively in restraint zone
The head for preventing restraint zone and tail portion of effect around tape drum 5 when rotating due under tension to be recessed into a shaped opening
In 52, and restraint zone is preferably wound into band again when the middle part of restraint zone setting thin bar 23 also facilitates in recycling
On box 5.
In the present embodiment, the two sides that the width of restraint zone 2 becomes narrow gradually region are respectively equipped with bound edge frame 6.
Setting bound edge frame 6 is effectively prevented fixation and is stuck in strip gab, so that the recycling of restraint zone goes wrong.
In the present embodiment, bound edge frame 6 is flexible plastic material.
So that the recycling of restraint zone is more smoothly.
In the present embodiment, the inner surface of restraint zone 2 is equipped with rubber layer 7；If the surface of rubber layer 7 is equipped with and is uniformly provided with
Dry rubber substance protrusion 71.
Effectively band-like scrap can be fixed in shaft 10.
In the present embodiment, the angle when tangent line and restraint zone 2 of restraint zone 2 and the winding of tape drum 5 point 8 are tightened is positive and negative 5 degree.
Winding point 8 is wound into the contact point of tape drum 5 for restraint zone.
The efficiency that winding and the recycling of restraint zone can effectively be improved prevents restraint zone and the band outlet 51 of tape drum 5 from rubbing
It wipes.
The present embodiment works in this way, after band-like scrap is drawn near shaft 10 by other devices, opens
Dynamic driving motor 3, under the rotation of driving motor 3, the restraint zone being wrapped on servo motor 9 starts to slide, with restraint zone
It is wound by driving motor 3, tape drum 5 is wound into the middle part of restraint zone and is existed, since the middle part width of restraint zone is less than circle on the inside of tape drum 5
Strip gab on circumferential surface contacts to directly pull out from strip gab with 10 surface of shaft, finally when in tape drum 5 entirely
When in the middle part of restraint zone, restraint zone, which has twined shaft 10, at this time extremely realizes the purpose that band-like scrap is fixed to shaft 10.
When no longer needing that shaft 10 is fixed, driving motor 3 is turned round, while servo motor 9 rotates, fastening
Band is recovered, during recycling, when fixed head is contacted with strip gab, since the effect of bound edge frame 6 makes
Restraint zone disengaging shaft 10 is obtained to return on tape drum 5.
Finally, it is stated that the above examples are only used to illustrate the technical scheme of the present invention and are not limiting, although referring to compared with
Good embodiment describes the invention in detail, those skilled in the art should understand that, it can be to skill of the invention
Art scheme is modified or replaced equivalently, and without departing from the objective and range of the technical program, should all be covered in the present invention
