Abstract
The invention discloses a manufacturing method for a needle tube pen point and a dotting mechanism. The manufacturing method comprises the following steps of (1) extruding a needle tube to form a pen point portion; (2) drilling a hole in the pen point portion along the axial direction; (3) performing dotting on the pen point portion along the radial direction; (4) trimming projections; (5) precisely trimming an opening of the pen point portion; and (6) mounting a steel ball and clamping the steel ball. In the manufacturing method, dotting is carried out along the radial direction by the dotting mechanism so that the projections are obtained, and the pen point is tapered. Compared with a method of forming a tapered pen point in a cutting manner, the manufacturing method has the advantages that the time is saved during dotting, so that the production efficiency is improved. The dotting mechanism comprises a wedge and a mandrel, wherein the mandrel is used for supporting and positioning the needle tube; the wedge is provided with an inclined plane; and the inclined plane of the wedge is matched with an inclined plane of the needle tube. When the wedge moves along the axial direction of the mandrel, the inclined plane of the wedge squeezes an inclined plane of an inclined plane body, so that the inclined plane body drives an ejector pin to move along the radial direction of the mandrel; the dotting accuracy is improved; and the production efficiency is improved.

Concrete condition understands the concrete meaning of above-mentioned term.
As shown in Figure 1, 2, the respectively top view of present pre-ferred embodiments striking mechanism and voussoir 4 and clinohedral 3
Structural representation.Striking mechanism of the present invention is mainly by fixed body 7, thimble 2, plug 1, voussoir 4, trimming part and cylinder institute structure
Become.Fixed body 7 is circular metallic object.The center of fixed body 7 is provided with plug 1, and plug 1 can be pole shape, and with fixation
Body 7 is coaxially disposed, and plug 1 is used for supporting the needle tubing 10 of positioning pen core.Fixed body 7 is evenly arranged with three with identical interval angles
Individual holding tank 11,120 jiaos of each 11 one-tenth of holding tank.It is fixed with the thimble seat for installing thimble 2 in each holding tank 11
8, thimble seat 8 is realized thimble 2 is installed by the mounting groove that is arranged in thimble fixed seat, so can ensure that thimble 2 can only be
Perpendicular to the motion of plug 1 axial plane, and cannot move in the axial place face of plug 1.Fixed body 7 is additionally provided with for installing fine setting
The trimming part fixed mount 9 of part.
The afterbody of thimble 2 is provided with clinohedral 3.Voussoir 4 clinohedral 3 and voussoir 4 are respectively provided with an inclined-plane, this two inclined-planes
Cooperate, so can make voussoir 4 along described plug 1 axially-movable when can by its inclined-plane extrude clinohedral 3 inclined-plane
And make clinohedral 3 drive thimble 2 along the radial motion of plug 1.The inclined-plane of clinohedral 3 parallel with the inclined-plane of voussoir 4 and with hang down
The straight plane in plug 1 axial direction becomes 15 degree of inclination angles.It is provided with spring 5 between voussoir 4 and clinohedral 3.Spring 5 voussoir 4 with tiltedly
The effect in mutual motion process between face body 3 is specially：During voussoir 4 is along plug 1 axially-movable, when voussoir 4
Contact clinohedral 3 simultaneously drives thimble 2 to when moving in the close direction of plug 1, and spring 5 is produced by compression along plug 1 direction
Radial direction reset force；When voussoir 4 continues the position being moved out clinohedral 3, this reset force can drive thimble 2 to away from plug
1 position movement is to return to position originally.
Trimming part includes screw rod 62 and the screw seat 61 being fixed on fixed body 7, and the inside of screw seat 61 is provided with screw, spiral shell
Matched with the screw thread of screw rod 62 periphery in hole.Trimming part is used for adjusting wedge 4 along plug 1 radial motion, and its mechanism is：
By one end of turn screw rod 62 so that its precession in screw seat 61, another end in contact voussoir 4 of screw rod 62 simultaneously drives voussoir
4 along plug 1 radially adjacent to plug 1, thus realizing to voussoir 4 to the regulation near plug 1, in the process, spring 5 is pressed
Contracting.Conversely, screw rod 62 screws out in screw seat 61, away from voussoir 4, the elastic force of spring 5 drives voussoir 4 remote to the other end of screw rod 62
Off-chip rod 1 motion, it is achieved thereby that to voussoir 4 to the regulation away from plug 1.
Cylinder is used for driving voussoir 4 along the axially-movable of plug 1 and to be attached thereto.Concrete structure as cylinder and principle
It is well known to those skilled in the art, will not be described here.
The operation principle of in present invention striking mechanism is described below.
Before getting operation ready, the needle tubing 10 of pen core is enclosed within the outside of plug 1 and so that it is fixed.Will by turn screw rod 62
Voussoir 4 is good along the position adjustments of plug 1 radial direction.Then, start cylinder, voussoir 4 is made a certain along plug 1 radial direction by air cylinder driven
During the motion of direction, voussoir 4 contacts and drives clinohedral 3 along plug 1 radially adjacent to plug 1, and the syringe needle of thimble 2 impacts needle tubing 10,
Thus getting a little；Continue to be moved out the position of clinohedral 3 in voussoir 4 after, thimble 2 is under the compression of spring 5 away from plug 1
And return to initial position.Work as return hydraulic cylinder, voussoir 4 makees the counter motion along plug 1 radial direction, voussoir 4 contacts and drives inclined-plane again
Along plug 1 radially adjacent to plug 1, the syringe needle of thimble 2 impacts needle tubing 10 to body 3 again, gets a point again.So repeatedly.
The manufacture method of needle tubing 10 nib of the present invention, comprises the following steps：
(1) one end of needle tubing 10 is extruded by cold extrusion mode, form one and be used for the written portion of steel ball is installed；
(2) described nib portion is holed using boring vertically, obtain an installing hole；(3) the written portion through step (2) is used
Striking mechanism is radially got ready, obtains three salient points；(4) carry out end face to salient point to polish and chamfering；(5) according to be processed
Size refine is carried out to the opening through step (3) nib portion；(6) steel ball is loaded after described opening, with clamping device to this
Opening is clamped.
Although the above more term employing expression structure, such as " plug 1 ", " clinohedral 3 ", " voussoir 4 ", " thimble
2 " etc., but it is not precluded from the possibility using other terms.It is used for the purpose of more easily describing and explaining using these terms
The essence of the present invention；It is all contrary with spirit of the present invention for being construed as any additional restriction.
Describe the know-why of the present invention above in association with specific embodiment.These descriptions are intended merely to explain the present invention's
Principle, and limiting the scope of the invention can not be construed to by any way.Based on explanation herein, the technology of this area
