Service life.The process that valve face is strengthened is in air valve matrix conical surface built-up welding Ni-Cr alloy, by roll unit in valve face overlay cladding
If surface rolls the groove of arterial highway concentric circles with idler wheel, then removes valve face surplus with the method for machining, in this way after rolling
Valve face generate flow harden improve hardness, achieve the effect that valve face strengthen.
Rolling wheel for valve face rolling will also be controlled according to technological requirement and be rolled other than needing to apply big load pressure
The position of depth and each concentric circles.Otherwise for the air bleeding valve of different size, the initial position of rolling wheel also needs to adjust.Therefore
On exhasut valve stem circular cone valve face roll unit, the structure of rolling wheel and driving rolling wheel is particularly important.
Existing rolling device rolling path is fixed, and rolling size is fixed, and cannot meet the exhasut valve stem processing of plurality of specifications
It is required that cannot meet exhasut valve stem circular cone valve face carries out flow harden by rolling, the technological requirement of valve face intensity is improved.
Invention content
To solve the above-mentioned problems, the utility model provides a kind of valve rod circular conical surface multiple tracks ditch groove rolling device, can be effective
Flow harden is carried out to exhasut valve stem circular cone valve face, improves valve face intensity, and the utility model can meet plurality of specifications row
Air valve processing request.
Valve rod circular conical surface multiple tracks ditch groove rolling device described in the utility model include engine base, rolling wheel, rolling wheel slide and
Roll oil cylinder.Sliding block is installed, rolling wheel is fixedly mounted on the sliding block lower end, and rolling oil cylinder, which drives, to be slided in the rolling wheel slide
Block moves up and down in rolling wheel slide, to drive rolling wheel to move up and down.
The upper surface of the engine base is inclined-plane, and the stand bevel gradient is consistent with valve rod circular conical surface gradient, and rolling wheel is made to exist
When being processed to valve rod, with valve rod circular conical surface on same inclined-plane, if to process the groove of arterial highway concentric circles.The engine base
Installation translation slide, the translation slide are moved up and down by translation slide driving mechanism drives edge stand bevel on inclined-plane, the rolling
Pinch roller slide is fixedly mounted on the front of translation slide.It translates slide driving mechanism driving translation slide and rolling wheel slide moves
It is dynamic, to drive rolling wheel to move, to meet to valve rod process requirements.
The translation slide driving mechanism includes servo motor and ball-screw, the servo motor, ball-screw installation
In stand bevel.Servo motor drives ball screw turns, to drive translation slide movement.
Preferably, the sliding block is cylindrical slide, and the cross sectional shape of the cylindrical slide is rectangle.Sliding block is in rolling wheel slide
When interior drive rolling wheel moves up and down, it can prevent rolling wheel from occurring twisting phenomenon in rolling.
Rolling wheel slide top installation rolling cylinder installation seat, rolling oil cylinder are installed in rolling cylinder installation seat；
Piston thick stick one end of the rolling oil cylinder is connect with upper end of slide block, and the other end is connected with displacement sensor.When rolling oil cylinder stretches out
When band movable slider and rolling wheel move down, rolling wheel and the valve rod conical surface contact rotated and constantly downward pressurization carry out
Rolling, circular groove is formed on valve rod circular conical surface, after displacement sensor detects that gash depth reaches requirement, rolls oil cylinder
It retracts, rolling wheel lifts the rolling for completing the road groove.
Compressed oil cylinder is installed in the top of the translation slide, and compact heap is housed on the piston rod of compressed oil cylinder；Work as rolling wheel
When carrying out load rolling, the compact heap compresses translation slide, prevents translation slide from being jacked up.
Valve rod circular conical surface multiple tracks ditch groove rolling device described in the utility model, it is consistent with valve rod circular conical surface gradient by being arranged
Stand bevel, installation translation slide and rolling wheel rolls exhasut valve stem circular cone valve face so as to efficiently accomplish, improves valve face
Intensity；And the movement by translating slide and scroll wheel, plurality of specifications valve rod processing request can be met.

Specific implementation mode
As shown in Figure 1, valve rod circular conical surface multiple tracks ditch groove rolling device described in the utility model includes 1 He of engine base with inclined-plane
Slide 10 is translated, translation 10 integral installation of slide is on the inclined-plane of engine base 1.
As shown in Figure 1, the front installation rolling wheel slide 4 of translation slide 10；Column sliding block 3 can in rolling wheel slide 4
To slide up and down, rolling wheel 2 is mounted on 3 lower end of column sliding block and is rolled for groove；It rolls cylinder installation seat 5 and is mounted on rolling wheel
The piston thick stick one end on 4 top of slide, rolling oil cylinder 6 is connect with 3 upper end of column sliding block, and the other end is connect with displacement sensor 7.Pressure
Locking oil cylinder 8 is mounted on the top of translation slide, and compact heap 9 is housed on the piston rod of compressed oil cylinder.The movement of slide is translated by rolling
Ballscrew 11 and servo motor 12 drive.
Utility model works process is as follows：
When normal work, servo motor 12 drives ball-screw 11 to rotate, to drive translation slide 10 in stand bevel
On move up and down, make to be mounted on the position for needing to roll groove on the rolling wheel 2 to valve rod circular conical surface of translation slide 10 front；Pressure
Locking oil cylinder 8 stretches out, and compact heap 9 compresses translation slide 10, prevents translation slide 10 when rolling from being jacked up.Then, rolling oil cylinder 6 is stretched
Go out, column sliding block 3 and rolling wheel 2 driven to move down, the conical surface contact of rolling wheel 2 and the valve rod rotated and constantly to
Lower pressurization is rolled, and circular groove is formed on valve rod circular conical surface.When displacement sensor 7 detects that gash depth reaches requirement
