Description
Technical field
The utility model relates to bevel gear shaft manufacture fields, and in particular to a kind of small coning gear shaft drills through hole tool.
Background technique
Bevel pinion needs to process through-hole, usually uses general 8 through-hole of wagon drill φ, logical for the axis class greater than 250mm long
Exist in the process in hole as following drawbacks: the first, lengthening drill bit consumes big (lengthening drill bit is costly)；The second, rejection rate
High (drill bit, which breaks into product, to be taken out)；Third, processing single products time are longer (about 25 minutes).That is, single-piece
Processing charges is higher, and production cost investment is big, and product quality is uncontrollable
Utility model content
The purpose of this utility model is in view of the deficiencies of the prior art, to provide a kind of small coning gear shaft and drill through hole tool, energy
Bit wear is enough reduced, production consumption is reduced.
The technical solution of the utility model is achieved in that a kind of small coning gear shaft drills through hole tool, including upper positioning
Plate, lower positioning plate, upper positioning plate, lower positioning plate are connected by support rod, and lower positioning plate is connected with top, and upper positioning plate side is set
There is side bolt hole, upper positioning plate side is additionally provided with V-type pawl and link bolt hole, and V-type pawl, pressing plate is bolted in movable cushion block
It is equipped with threaded hole and U-shaped hole, pressing plate is connected with upper positioning plate.
Two side angles of the V-type pawl are 90 °.
The top lower part is the pedestal connecting with lower positioning plate, and top is the cone that apex angle is 60 °.
Compared with prior art, the utility model, which has the advantage that, solves various axis products drilling deep hole techniques；Belong to
In the double positioning clamping designs of adjustable concentricity；Structure design is simple, versatile, at low cost, easy to operate.

Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are under that premise of not paying creative labor
Every other embodiment obtained, fall within the protection scope of the utility model.
As shown in Fig. 1~10, a kind of small coning gear shaft drills through hole tool, including upper positioning plate 1, lower positioning plate 3, upper positioning
Plate 1, lower positioning plate 3 are connected by support rod 2, and lower positioning plate 3 is connected with top 4, and upper 1 side of positioning plate is equipped with side bolt hole 1-
1, upper 1 side of positioning plate is additionally provided with V-type pawl 1-3 and link bolt hole 1-2, and V-type pawl 1-3 is bolted in movable cushion block 6, pressure
Plate 5 is equipped with threaded hole 5-1 and U-shaped hole 5-2, and pressing plate 5 is connected by screw rod, nut with upper positioning plate 1.
Preferably, described two side angles of V-type pawl 1-3 are 90 °.
Further, top 4 lower part is the pedestal 4-1 connecting with lower positioning plate 3, and top is the cone that apex angle is 60 °
Body 4-2.
The utility model is two end positioning device of axis products designed according to " six point location principle of tooling ", and one end uses
The positioning of top 4 pairs of axis classes centre bore (small coning gear shaft 7), it is top can be according to axial workpiece length self-changeable；The other end uses
The positioning of Atria point location, i.e. V-type pawl 1-3, two positioning surface of V-type pawl are all connected with movable cushion block 6, can be according to not coaxial class diameter
The thickness using movable cushion block is calculated, another freedom degree point is designed using revolving pressing plate 5, and pressing plate both ends standing screw makes
With design-adjustable, not coaxial class diameter can be met and used.
(i.e. two end positioning device of axis class) is carried out using four contour support rods 2 between upper positioning plate 1, lower positioning plate 3
Connection guarantees above and below flatness and symmetry.
It after the tooling of the application adjusts concentricity, can start to produce in batches, avoid one product of every clamping and require
Use dial gauge correction course；Clamping workpiece and convenient disassembly use convenient for batch production；Drilling can satisfy product requirement,
Chip removal is preferable in drilling process, and the single-piece drilling time kept in reserve improved 6 times more originally, and single-piece manufacturing expense is dropped compared to previous external coordination
Low 70% or more；Bit wear is smaller, and production consumption can be substantially reduced on having grasped depth drill operating procedure.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
