Description
Technical field
This utility model relate to chipping allowance less bevel gear machining, more specifically one be easy to processing,
Reduce mismachining tolerance, the clamp for machining of suitable machining high-precision bevel gear.
Background technology
Having many uses of bevel gear, is the strength member in various plant equipment, such as lathe, aircraft, steamer and daily life
Automobile in work, electric motor car etc. will use various bevel gear.Currently along with the development of technology, the Production requirement of bevel gear is more
Coming the biggest, required precision is more and more higher, and the control to its cost simultaneously also improves, and how can obtain in the case of reducing cost
To high-precision product, have become as the productive target that factory is current.
The machining of bevel gear always affects the final precision of product and the key factor of cost, and traditional bevel gear machine adds
Work the most first drill centers on drilling machine, then withstands centre bore processing end face, boss external diameter etc. with thimble, finally grabs with three
Promptly end face car endoporus, chamfering.The defect of this technique is it is obvious that be exactly that operation is many, and beat is slow, and end face, boss external diameter and
Endoporus is not to complete in one procedure, and repeated clamping error strengthens, and affects Product Precision.
Utility model content
This utility model is for the deficiencies in the prior art, it is provided that a kind of bevel gear machining fixture, reduces manufacturing procedure, carries
High workload efficiency, increases the final precision of product, reduces production cost.
In order to solve above-mentioned technical problem, the technical solution adopted in the utility model is:
A kind of bevel gear machining fixture, including first operation fixture and second operation work fixture, first operation is pressed from both sides
Tool includes determining core tooth mould one and movable thimble, determines core tooth mould one and is provided with draw-in groove, and one end of workpiece is stuck in draw-in groove, movable thimble top
Live the other end of workpiece；Second operation work fixture includes determining core tooth mould two, pressing plate, hydraulic mandril, pole, installing plate, determines core tooth
Mould two is arranged in the middle of installing plate, and pole is installed on a mounting board, and pole is provided with 2 and symmetrical centered by determining core tooth mould two,
Pressing plate is arranged on pole, and one end of pressing plate is arranged on hydraulic mandril upper end, the other end of pressing plate be provided with trimming and with workpiece
Back cone matches, and one end of hydraulic mandril is arranged in installing plate.
Preferably, determining core Chi Mo bis-center and be provided with through hole, through hole is taper, and tapered distal end is provided with inclination angle, inclination angle and workpiece
Coupling.
Preferably, pole is hinged with pressing plate.
The beneficial effects of the utility model are:
1, this utility model simple in construction, reasonable in design, uses two procedures to complete the machining of bevel gear, decreases work
Sequence, reduces production cost.
2, this utility model uses first operation fixture, positions with determining workpiece faced by core tooth mould one, and movable thimble completes
Workpiece is held out against, it is not necessary to get out endoporus, reduce operation, cost-effective.
3, this utility model uses second operation work fixture, positions workpiece with determining core tooth mould, provides power by lathe
Making hydraulic strut hold out against pressing plate, pressing plate middle part has a mobilizable pole to be connected with fixture, forms a lever, finally
The pressure of hydraulic strut transmission makes to be completed the compression of workpiece by pressing plate by lever principle, and compressing position is first operation folder
Tool clamping workpiece rear car goes out back cone.Rear car goes out overall dimension.Without endoporus, cylindrical equidimension are divided into two procedures and complete,
Decrease the error that multiple clamping causes, improve product quality.
Accompanying drawing explanation
With detailed description of the invention, this utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is this utility model first operation clamp structure schematic diagram.
Fig. 2 is this utility model second operation work clamp structure schematic diagram.
Detailed description of the invention
Below in conjunction with accompanying drawing, embodiment of the present utility model is described in detail, but this utility model can be by right
Require that the multitude of different ways limiting and covering is implemented.
As it can be seen, the open a kind of bevel gear machining fixture of this utility model, including first operation fixture and second
Procedure fixture, first operation fixture includes determining core tooth mould 1 and movable thimble 2, determines core tooth mould 1 and is provided with draw-in groove, workpiece 3
One end be stuck in draw-in groove, then movable thimble 2 withstands the other end of workpiece, it is not necessary to get out endoporus, reduce operation, save into
This；Second operation work fixture includes determining core tooth mould 24, pressing plate 3, hydraulic mandril 4, pole 8, installing plate 7, determines core tooth mould 24 peace
Being contained in the middle of installing plate 7, pole 8 is arranged on installing plate 7, and pole 8 is provided with 2 and symmetrical centered by determining core tooth mould 24, pressure
Plate 3 is arranged on pole 8, and one end of pressing plate 3 is arranged on hydraulic mandril 4 upper end, and the other end of pressing plate 3 is provided with trimming and workpiece
Back cone 9 match, one end of hydraulic mandril 4 is arranged in installing plate 7.
In the present embodiment, determining core tooth mould 24 center and be provided with through hole, through hole is taper, and tapered distal end is provided with inclination angle, inclination angle
Mate with workpiece 3.Pole 8 is hinged with pressing plate 3.In use, pole works as fulcrum, hydraulic mandril, jack-up pressing plate, pressing plate
Workpiece pressing, it is that first operation clamp workpiece rear car goes out back cone that this utility model compresses position.Rear car goes out whole chi
Very little.Without endoporus, cylindrical equidimension are divided into two procedures and complete, decrease the error that multiple clamping causes, improve product
Quality.
Above-described this utility model embodiment, is not intended that the restriction to this utility model protection domain, any
Amendment, equivalent and the improvement etc. made within spirit of the present utility model and principle, should be included in this utility model
Claims within.
