Description
Technical field
The present invention relates to a kind of cutting tool and its application method, especially a kind of rear cover pivoted arm bilateral ball cutting tool
And its application method.
Background technique
Rear cover pivoted arm main operational principle is to unlock and lock, and moving rotary position is by oscillating bearing structure composition.Section
Bearing is mounted in the ball of rear cover pivoted arm, when installation very to the required precision of the verticality of bearing centre and part base solid end face
It is high: and the installation of bilateral oscillating bearing, with greater need for the concentricity requirement in two bearings hole in addition to above-mentioned requirements, otherwise, it may appear that
After bearing installation, matched pin shaft cannot be penetrated in two bearings hole；Or after penetrating pin shaft, bearing is unable to flexible rotating
The phenomenon that.Existing processing method is turning successively to be carried out to ball, but such method is it is difficult to ensure that two ball concentricities,
Machining accuracy is not high, and part quality is low after processing.
Summary of the invention
In order to solve the above-mentioned technical problems, the present invention provides a kind of rear cover pivoted arm bilateral ball cutting tool and its uses
Method.By being provided with positioning pin in main body, positioning plate is arranged in main body by support, and cylinder is provided on positioning plate
Bolt guarantees the concentricity of two ball of part, and pressure plates I and pressure plates II are provided on positioning plate and main body for retaining element
Position.Two ball concentricities for solving part existing in the prior art cannot ensure that machining accuracy is low, part quality
The technical problem of difference.
To achieve the goals above, the technical solution adopted by the present invention is that: rear cover pivoted arm bilateral ball cutting tool, it is special
Sign is: being provided with positioning pin at the central axis of main body, support is provided in main body, positioning plate is connected to the upper surface of support
It is stretched out to the upper horizontal of positioning pin, is provided with through-hole on positioning plate at position corresponding with positioning pin, the insertion of cylinder bolt is logical
Hole is coaxial with positioning pin, using being bolted pressure plates I on positioning plate；Pressure plates II, pressing plate have been bolted in main body
The front end II is in contact with the side of positioning pin.
The pressure plates II front end is provided with being capable of U-type groove of the clamping on the outside of positioning pin.
Adjustable supports are provided on the positioning plate.
Counterweight is installed in the main body.
The application method of rear cover pivoted arm bilateral ball cutting tool, the steps include:
1) part side inner hole, is passed through into positioning pin, adjustment bolt is pressed in pressure plates II on feature side-wall, with constant zero
The position of part；
2) positioning plate, is passed through using cylinder bolt, keeps cylinder bolt and positioning pin coaxial, and adjust adjustable supports and pressing plate
The another side of part is fixedly clamped by I；
3) cylinder bolt, is extracted, by the tool clamping on numerically-controlled machine tool, ball on the upside of turning；
4), by 180 ° of fitting turnover, the ball of turning is solid using positioning finger setting, repeat step 1) to 3), vehicle
Cut part other side ball.
The beneficial effects of the present invention are: by being provided with positioning pin in main body, positioning plate is arranged by support in master
On body, it is provided with cylinder bolt on positioning plate, guarantees the concentricity of two ball of part, is provided on positioning plate and main body
Pressure plates I and pressure plates II are used for retaining element position.The present invention using the above structure and method, provide it is a kind of it is easy to process, make
It with simple structure, while can guarantee the concentricity of part ball, ensure that processing quality and precision, solve existing skill
Two ball concentricities of part present in art cannot ensure that machining accuracy is low, the technical problem of part quality difference.

Specific embodiment
Rear cover pivoted arm bilateral ball cutting tool, structure are as follows: positioning pin 7, main body are provided at the central axis of main body 2
Be provided with support 3 on 2, the upper surface that positioning plate 4 is connected to support 3 is stretched out to the upper horizontal of positioning pin 7, on positioning plate 4 with
Through-hole is provided at the corresponding position of positioning pin 7, cylinder bolt 8 is inserted into through-hole and positioning pin 7 is coaxial, and spiral shell is used on positioning plate 4
It tethers and is connected to pressure plates I 6；It is bolted pressure plates II 1 on the body 2,1 front end of pressure plates II connects with the side of positioning pin 7
Touching.
1 front end of pressure plates II is provided with being capable of U-type groove of the clamping on the outside of positioning pin 7.
Adjustable supports 9 are provided on the positioning plate 4, adjustment adjustable supports 9 can prop up 10 upper side of part
Support, adjustable supports 9 are clamped fixation to 10 upper side of part together with pressure plates I 6.
Counterweight 5 is installed, main body 2 is a disc structure, is needed this equipment is whole in numerical control machine in the main body 2
On bed, process its rotation to part, since the structures such as L shape support 3, positioning plate 4, pressure plates I 6 in main body are all in main body
2 the same side, so gravity center instability can be led to the problem of when main body 2 rotates, so the master in the isostructural other side of support 3
