Description
Technical field
It the utility model is related to a kind of pcb board milling cutter, and in particular to a kind of pcb board milling handle.
Background technology
At present, common dental drill drill（Drill bit）Usually handle of a knife and drill are formed in one the drill of structure, due to whole
Its production cost is larger for wolfram steel for body material, is not easy to save cost.In order to save cost, Some Enterprises are by handle of a knife and brill
Knife separately produces, and is welded as a whole afterwards by way of welding.However, the handle of a knife of prior art also needs to help in welding
Solder flux, operation when this is to welding requires more strict, not only bad for the efficiency for improving work, and to welding technique more
Strictly, it is necessary to be designed handle of a knife for this, to improve welding efficiency.
The content of the invention
The purpose of this utility model is overcome the deficiencies in the prior art and reasonable, the manufacturing cost that provides a kind of design structure
It is low, a kind of pcb board milling handle of convenient welding.
In order to realize the purpose of this utility model, what the technical solution of the utility model was realized in：A kind of PCB
Plate milling handle, including handle of a knife body, described handle of a knife bodies top is arranged at plumb joint and bottom is provided with connector, described
The tapered structure of plumb joint and the angle of plumb joint and handle of a knife body be 12 ° -25 °, be provided with cone at the top of described plumb joint
Shape joint, described taper joint is highly 0.1-0.2 ㎜ and taper joint apex angles are 120 ° -175 °.
The tapered structure of connector that described handle of a knife body bottom portion is set, described connector inclined-plane press from both sides with handle of a knife body
Angle is 30 ° and height is 0.8 ㎜.
The connector structure spherical in shape that described handle of a knife body bottom portion is set.
Beneficial effect is caused by the utility model：The utility model is by handle of a knife and drill bit separation, and handle of a knife is tied
Curve guide impeller on structure, because existing milling cutter is usually wolfram steel material, production cost is higher on the whole, and by only designing knife
Handle and material is stainless iron, greatly reduces production cost.On the other hand, set by the top of the plumb joint in handle of a knife body
The taper joint that one triangular pyramidal and height are 0.1 ㎜, facilitate and weld drill after being directly heated in welding
It is connected on plumb joint.
Generally, the utility model has design structure reasonable, and manufacturing cost is low, the advantages that convenient welding.
Brief description of the drawings
Fig. 1 is the utility model overall structure diagram.
Fig. 2 is the utility model another kind design structure schematic diagram.
In figure：1- handle of a knife body 2- plumb joint 3- connector 4- taper joints.
Embodiment
Below in conjunction with the accompanying drawings to embodiment further instruction of the present utility model.
Embodiment 1
As shown in figure 1, a kind of pcb board milling handle, including handle of a knife body 1, the described top of handle of a knife body 1 are arranged at weldering
Joint 2 and bottom are provided with connector 3, and the angle of described 2 tapered structure of plumb joint and plumb joint 2 and handle of a knife body 1 is
12 ° -25 °, the described top of plumb joint 2 is provided with taper joint 4, and the described height of taper joint 4 is 0.1-0.2 ㎜ and taper
The apex angles of joint 4 are 120 ° -175 °.
The 3 tapered structure of connector that the described bottom of handle of a knife body 1 is set, the described inclined-plane of connector 3 and handle of a knife sheet
The angle of body 1 is 30 ° and height is 0.8 ㎜.
The utility model is when in use：The plumb joint of tapered structure is provided with the top of handle of a knife body, plumb joint is oblique
Angle is 20 ° between face and handle of a knife body, is highly 1.2 ㎜, and one is set at the top of plumb joint in trigonal pyramidal structure
Taper joint, its height are 0.155 ㎜, and when welding drill, drill is directly welded in welding by G after directly heating taper joint
It is more convenient during welding on head, separately reduce production cost and time.By the design of butt joint, make its handle of a knife
The intensity of body in itself is higher, equally also increases the intensity of drill and handle of a knife entirety, and the cost service life after support is longer.
The 3 tapered structure of connector that the bottom of handle of a knife body 1 is set, the described inclined-plane of connector 3 and the angle of handle of a knife body 1 be 30 ° and
It is highly 0.8 ㎜, handle of a knife can be firmly withstood on rig.
Implement 2
A kind of pcb board milling handle, including handle of a knife body 1, the described top of handle of a knife body 1 are arranged at plumb joint 2 and bottom
The angle that portion is provided with connector 3, described 2 tapered structure of plumb joint and plumb joint 2 and handle of a knife body 1 is 12 ° -25 °, institute
The top of plumb joint 2 stated is provided with taper joint 4, and the described height of taper joint 4 is 0.1-0.2 ㎜ and the top of taper joint 4
Angle is 120 ° -175 °.
2 structure spherical in shape of connector that the described bottom of handle of a knife body 1 is set.
The utility model is when in use：The plumb joint of tapered structure is provided with the top of handle of a knife body, plumb joint is oblique
Angle is 20 ° between face and handle of a knife body, is highly 1.2 ㎜, and one is set at the top of plumb joint in trigonal pyramidal structure
Taper joint, its height are 0.155 ㎜, and when welding drill, drill is directly welded in welding by G after directly heating taper joint
It is more convenient during welding on head, separately reduce production cost and time.By the design of butt joint, make its handle of a knife
The intensity of body in itself is higher, equally also increases the intensity of drill and handle of a knife entirety, and the cost service life after support is longer.
2 structure spherical in shape of connector that the bottom of handle of a knife body 1 is set, reduces technical process and the time of processing, can also improve production
