Abstract
A kind of numerically controlled lathe boring grab, it is that the centre for including clamp body clamp body is formed with round taper hole, it is formed with and round taper hole axis identical internal thread hole in the big clamp body through one end of circular cone body opening, two clamping devices are set in round taper hole, clamping device is had by an outer surface to be formed with round taper hole taper identical cone from axial location subdivision, V-shaped groove is formed with the plane axis line position of described clamping device, a binding nut is installed in a manner of screw thread coordinates in internal thread hole, the centre of binding nut has clear opening, it is preferable with versatility, the advantages of easy to use, also have simultaneously simple in construction, parts are less, manufacture easy for installation, lower-cost advantage.
Description
Technical field
The present invention relates to a kind of automation field, and in particular to numerically controlled lathe field, more particularly to a kind of numerically controlled lathe
Drilling clamps.
Background technology
At processing center of numerical-control machine tool hole typically or using traditional processing method, fluted drill is mounted in drill chuck
On, then by drill chuck on tail stock, the rocking handle by shaking tail stock carries out the drilling of centre bore, this method
Not only cumbersome laborious, efficiency is low, and the machining accuracy in the hole processed is very poor, and existing one kind will be bored by frock clamp
Processing mode of the head on knife rest, but the drill bit of this fixture clamping can only clamp one kind, and also fixation is very insecure,
It is easy to generation to circumferentially rotate, influences crudy, therefore, Chinese utility model patent number is 201,620,788,922 8,
Authorization Notice No. is the U of CN 206047159, entitled " a kind of numerically controlled lathe series boring grab " disclose can clamp compared with
More specification drill bits, the technology in drilling different size aperture is realized, still, the technology is to need to use end due to the defects of protruding
Special fluted drill provided with spline structure, described special fluted drill is fixedly mounted in drill bushing, and the diameter of bore of drill bushing is big
Small different, the fluted drill of different size uses the different drill bushing of diameter of bore, causes parts more, it has not been convenient to manage,
It is poor to be particularly present versatility, it has not been convenient to the use of production.
The content of the invention
It is an object of the invention to：For the drawbacks described above in the presence of prior art, the present invention provides a kind of new
Numerically controlled lathe boring grab, overcome the drawbacks described above in the presence of prior art.
Technical scheme is used by the present invention realizes above-mentioned purpose：A kind of described numerically controlled lathe boring grab, it is
By clamp body（1）, clamping device（2）, binding nut（3）Formed, described clamp body（1）Centre be formed with round taper hole
（4）, in circular cone body opening（4）Clamp body through one end greatly（1）It is formed with and round taper hole axis identical internal thread hole（5）, institute
The round taper hole stated（4）Two clamping devices of interior setting（2）, described clamping device（2）It is to be had and circle by an outer surface
Bellmouth（4）Taper identical cone forms from axial location subdivision, in described clamping device（2）Plane axis
V-shaped groove is formed with position（7）, in described internal thread hole（5）It is interior that a binding nut is installed in a manner of screw thread coordinates（3）,
Described binding nut（3）Centre there is clear opening（6）.
The present invention so works, and unclamps binding nut during beginning（3）, by drill bit（8）Retained part be placed on two
Individual clamping device（2）Relative V-shaped groove（7）It is interior, now tighten binding nut（3）, two clamping devices（2）Just simultaneously to center
Axial location is shunk, so as to which drill bit be clamped.
Beneficial effect：The present invention without doing special manufacture or transformation to drill bit, and can clamp not when clamping drill bit
The drill bit of same specification, have versatility it is preferable, it is easy to use the advantages of, while also have it is simple in construction, parts are less, manufacture
Easy for installation, lower-cost advantage.
Brief description of the drawings
Fig. 1 is the front view of the present invention；
Fig. 2 is Fig. 1 Section A-A figure.
Shown in figure：1 it is clamp body, 2 be grip device, 3 be binding nut, 4 be round taper hole, 5 is internal thread hole, 6
It is clear opening, 7 be V-shaped groove, 8 is drill bit.
Embodiment
With reference to Fig. 1, Fig. 2, embodiment of the invention is：
A kind of described numerically controlled lathe boring grab, it is by clamp body（1）, clamping device（2）, binding nut（3）Formed,
Described clamp body（1）Centre be formed with round taper hole（4）, in circular cone body opening（4）Clamp body through one end greatly（1）It is formed with and circle
Taper axially bored line identical internal thread hole（5）, in described round taper hole（4）Two clamping devices of interior setting（2）, described folder
Tight device（2）It is to be had by an outer surface and round taper hole（4）Taper identical cone forms from axial location subdivision,
In described clamping device（2）Plane axis line position on be formed with V-shaped groove（7）, in described internal thread hole（5）It is interior with screw thread
The mode of cooperation installs a binding nut（3）, described binding nut（3）Centre there is clear opening（6）.
Claims (2)
1. a kind of numerically controlled lathe boring grab, it is by clamp body（1）, it is characterised in that：It also includes clamping device（2）, folder
Tight nut（3）, clamp body（1）Centre be formed with round taper hole（4）, in circular cone body opening（4）Clamp body through one end greatly（1）It is formed with
With round taper hole axis identical internal thread hole（5）, in described round taper hole（4）Two clamping devices of interior setting（2）, institute
The internal thread hole stated（5）It is interior that a binding nut is installed in a manner of screw thread coordinates（3）, described binding nut（3）Centre
With clear opening（6）.
