Description
Technical field
The utility model belongs to Gear Processing field, and in particular to a kind of gear compound graduation hole machined installs fixture.
Background technology
At present, the useful coordinate boring correction endoporus of the method for processing and the line at tooth socket center process 8 index holes and by
The line at hole and tooth socket center is manually crossed, and drilling machine processes 8 index holes to the layout line, both modes process in gear
The index hole that hole center and the angle position of the tooth socket line of centres require.
Coordinate boring is to find bore centre coordinate with amesdial, then the seat at a tooth socket center is found with amesdial
Mark, according to the line of two centre coordinates, processes 8 index holes of gear, ensures one of tooth of gear and the center in hole
The angle requirement of line and 8 index holes.Which processing efficiency is low, can not meet requirements of mass production.
Hatched manner is the line that two centre coordinates are marked by artificial crossed, and 8 index holes are drawn further according to center line
Center line processes 8 index holes with drilling machine, and which machining accuracy is low, can not meet drawing requirement.
Utility model content
Technical problem to be solved in the utility model is in view of the above shortcomings of the prior art, to provide a kind of gear point
Hole machined installs fixture is spent, simple in structure, part installation is quick, reliable, and gear is installed on fixture after positioning, can directly be added
Work 8 index holes, significant increase processing efficiency.
Technical solution is used by the utility model：A kind of gear compound graduation hole machined installs fixture, including cuboid
The pedestal of shape, the pedestal wherein one side are equipped with datum level, and the base upper surface is equipped at a wherein short side edge
Inside is provided with the dead head of endoporus, and axially bored line is parallel with pedestal datum level in the dead head, is slided in the dead head endoporus
It is connected with top, the top axis is parallel with pedestal datum level, and the base upper surface is equipped at another short side edge
Mandrel, the mandrel axis is vertical with pedestal, and the mandrel includes being vertically installed in matching with bore for base upper surface
Fixing axle and with fixing axle be integrally formed and far from pedestal connecting shaft, the fixed shaft diameter be more than connection shaft diameter, institute
It states and lower gasket is socketed in fixing axle, Upper gasket is socketed in the connecting shaft, is located above Upper gasket in the connecting shaft
Position is additionally provided with locking nut.
In one embodiment, the dead head is set to base upper surface by screw.
In one embodiment, the dead head upper surface is equipped with the fastening nail connected with dead head endoporus.
The beneficial effects of the utility model are：8 index holes of gear part are processed by fixed coordinate points, and
Ensure gear compound graduation hole center and bore center and the angle requirement of the tooth socket line of centres；Compared with prior art, this reality
Simpler with structure, high precision machining is efficient, and reliability is high, at low cost.

Specific embodiment
The utility model is described in further detail below in conjunction with the accompanying drawings and the specific embodiments.
As shown in Figure 1, Figure 2 and Figure 3, a kind of gear compound graduation hole machined installs fixture, the pedestal 1 including cuboid,
The pedestal 1 wherein one side is equipped with datum level 10, and 1 upper surface of pedestal is opened at a wherein short side edge equipped with inside
There is a dead head 3 of endoporus, axially bored line is parallel with 1 datum level 10 of pedestal in the dead head 3, is slided in 3 endoporus of dead head
Top 2 are connected with, top 2 axis is parallel with 1 datum level 10 of pedestal, and 1 upper surface of pedestal is close to another short side edge
Place is equipped with mandrel 6, and 6 axis of mandrel is vertical with pedestal 1, and the mandrel 6 includes be vertically installed in 1 upper surface of pedestal and tooth
It takes turns the matched fixing axle 61 of 7 endoporus and is integrally formed with fixing axle 61 and the connecting shaft 62 far from pedestal 1, the fixing axle 61 are straight
Diameter is more than 62 diameter of connecting shaft, is socketed with lower gasket 8 in the fixing axle 61, Upper gasket 4, institute are socketed in the connecting shaft 62
It states the position being located in connecting shaft 62 above Upper gasket 4 and is additionally provided with locking nut 5.
In the present embodiment, the dead head 3 is set to 1 upper surface of pedestal by screw 11.
In the present embodiment, 3 upper surface of dead head is equipped with the fastening nail 9 connected with 3 endoporus of dead head.
When this installs fixture is processed, this fixture is installed on boring machine.It is top by gear 7 to be processed on mandrel 6
2 are inserted into tooth socket, and buckling nut locks gear 7.By correcting 1 datum level 10 of pedestal and mandrel 6, you can pass through fixed seat
Punctuate processes 8 index holes of 7 part of gear, and ensures 7 index hole center of gear and 7 endoporus center of gear and tooth socket center
The angle requirement of line.
