Description
Technical field
The utility model belongs to screw thread cutting technical field, and in particular to a kind of device for clamping chasing cutter.
Background technique
Tapping machine is a kind of lathe with screw tap machining internal thread, it is a kind of most widely used internal thread machining machine
Bed.Existing most screw tap is directly to be clamped by the three-jaw of tapping machine drill chuck, and the main shaft rotation by tapping machine provides torque and carries out
Internal thread machining.Since the side of die hob fixing end is not bonded with the contact surface of three-jaw, not so as to cause three-jaw clamping force
Stablize.A kind of the most common situation is that the main shaft of tapping machine is also rotating, and screw tap has stopped rotating, 30 left sides of every processing
Right hole just needs again screw tap of clamping, and processing efficiency is low.
Utility model content
The utility model aims to solve at least one of the technical problems existing in the prior art.For this purpose, the utility model mentions
A kind of screw tap clamping device out, the screw tap clamping device, which has, prevents screw tap from skidding, and quickly positioning, clamping times are few etc. excellent
Point.
The screw tap clamping device of the embodiment of the utility model first aspect, including collet, the collet side and quick change
Screw tap connector is connected, and the other side of the collet has the mounting rod extended from collet axis direction, and the mounting rod is trigone
Rod structure is inserted into the three-jaw of drill chuck by means of the mounting rod, and three sides of the mounting rod are abutted with three-jaw.
The screw tap clamping device of embodiment according to the present utility model, screw tap are fixed on collet by quick change screw tap connector
On, stable connection between screw tap and quick change screw tap connector will not be loosened due to the operation vibration of tapping machine easily.In view of collet
On mounting rod be triangular prism structure, the side of triangular prism and the three-jaw of tapping machine drill chuck fit closely, effectively avoid skidding
Phenomenon.When screw tap needs replacing, it is only necessary to quick change screw tap connector is pushed, to realize that screw tap quickly positions and screw tap fills
Press from both sides the few advantage of number.
The additional aspect and advantage of the utility model will be set forth in part in the description, partially will be from following description
In become obvious, or recognized by the practice of the utility model.

Specific embodiment
The embodiments of the present invention are described below in detail, examples of the embodiments are shown in the accompanying drawings, wherein from beginning
Same or similar element or element with the same or similar functions are indicated to same or similar label eventually.Below by ginseng
The embodiment for examining attached drawing description is exemplary, and is only used for explaining the utility model, and should not be understood as to the utility model
Limitation.
Below with reference to Figure of description description according to the screw tap clamping device 10 of the utility model first aspect embodiment.
As shown in Figs 1-4, screw tap clamping device 10 according to the present utility model, including collet 100 and quick change screw tap connector
200。
Specifically, collet 100 is installed on the three-jaw of tapping machine drill chuck, screw tap 20 is installed on quick change screw tap connector 200,
It is connected between collet 100 and quick change screw tap connector 200.
The right side of the side of collet 100 as shown in figure 1 is connected with quick change screw tap connector 200, screw tap 20 and quick change screw tap connector
Stable connection between 200 will not be loosened due to the operation vibration of tapping machine easily.
The left side of the other side of collet 100 as shown in figure 1 has mounting rod 101, and mounting rod 101 is from the axis side of collet 100
Extend namely the length direction of collet 100, mounting rod 101 are stretched out from the side far from quick change screw tap connector 200.Mounting rod 101
For being sequentially connected with three-jaw.
Since the bearing surface of the three-jaw of drill chuck forms a bottom surface similar to the structure of triangle, by mounting rod 101
Be set as triangular prism structure, when mounting rod 101 be inserted into drill chuck three-jaw in, three sides 1011 of mounting rod just with three-jaw
Bearing surface abuts, and fixed form is secured, effectively avoids skidding.When screw tap needs replacing, it is only necessary to push quick change screw tap connector
, to realize that screw tap quickly positions and the few advantage of screw tap clamping times.
Optionally, when the bearing surface of the three-jaw of drill chuck forms the structure of a bottom surface equilateral triangle, mounting rod can be with
It is set as regular triangular prism structure, the bearing surface of the three-jaw of drill chuck and three sides 1011 of mounting rod fit closely, will not be easily
It skids.Moreover, collet 100 can be installed on the three-jaw of drill chuck, do not need often to unload.
Optionally, collet 100 is provided with mounting hole 102 in the side of installation quick change screw tap connector 200, and mounting hole 102 is certainly
The left side of collet 100 extends internally certain distance along the axis of collet 100, quick change screw tap connector 200 by mounting hole 102 with
Collet 100 is sequentially connected.Quick change screw tap connector 200 is existing standard component.
Optionally, quick change screw tap connector 200 has the first opening 201 of fixed screw tap 20 in the side far from collet 100,
Pass through 201 socket of the first opening between screw tap 20 and quick change screw tap connector 200.
It, can be in the opposite peace of collet 100 to further prevent relatively rotating between collet 100 and quick change screw tap connector 200
It fills and arranges multiple fixation holes 103 on the outer peripheral surface in hole 102, radial direction perforation of multiple fixation holes 103 along collet 100, multiple fixations
The inner orifice 1301 in hole 103 is communicated with the mounting hole 102.Multiple locking members 104 pass through multiple fixation holes 103 and are connected to quick change
On screw tap connector 200, to lock quick change screw tap connector 200.Fixation hole 103 can be arranged symmetrically can also be with unsymmetrical arrangement.
Screw tap clamping device 10 according to the present utility model is not needed frequently to be clamped screw tap 20, be improved indirectly
20 service life of screw tap.Consider simultaneously from quick orientation angle, screw tap clamping device 10 replaces drill point head clamping screw tap, replaces silk
It is simple to bore 20 processes.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Made any modifications, equivalent replacements, and improvements etc., should be included in the utility model within the spirit and principle of utility model
Protection scope within.
