Both ends of the surface carry out high-precision processing；Here acute angle is all on the basis of horizontal plane.
It is further perfect, shaft is fixed on sleeve, briquetting is rotatably connected at shaft, is provided with circle on the contoured surface of shaft
Arc-shaped slot, screw thread is equipped with the positioning screw with the cooperation of arc-shaped card slot on briquetting, and the right side of briquetting angle at an acute angle is set
The inclined surface two set.Here the effect of shaft, arc-shaped card slot, positioning screw, inclined surface two is to enable briquetting in lathe
When supporting rod high speed rotation, generated centrifugal force be able to drive briquetting arc-shaped card slot it is rectangular rotation and press platen；This
In the effect of inclined surface two of right side setting at an acute angle of briquetting be that lathe supporting rod is in high speed rotation and drives briquetting high speed
When rotation, generated centrifugal force is very big, inclined surface two due to setting at an acute angle, so can generate on inclined surface two towards left and
Component outwardly presses to will drive briquetting towards platen direction, and then is able to drive and is further driven to pull rod movement and drives
Resilient sleeve is opened to be stretched at the axis hole of valve rocker workpiece, lives valve rocker workpiece so as to further clamping.
Further perfect, the outside of sleeve is equipped with the cover being fixed on lathe supporting rod.Here the effect of cover is to rise
To safer effect, component when avoiding lathe supporting rod high speed rotation, on sleeve and briquetting since centrifugal force is excessive and
It throws away, at this moment can be blocked with cover, avoid injuring worker.
The utility model has the advantages that: the utility model smart structural design, rationally, utilize resilient sleeve, pull rod, use
Valve rocker workpiece is lived in opening clamping；Using platen, inclined surface one, when platen is driven by high speed rotation, it is generated from
Mental and physical efforts can be generated by one force resolution of inclined surface towards the movement of compressed spring direction, to will pull pull rod, and then can make elasticity
Set is opened and is clamped at the axis hole of valve rocker workpiece, so that valve rocker workpiece is lived in clamping；Utilize the effect of compressed spring
It is that energy band dynamic pressure disk resets；Using briquetting, under the action of compressed spring elastic force, so that platen is not moved in specific position, from
And ensure that the position between pull rod and resilient sleeve is accurate, just it can be covered with subsequent resilient sleeve at the axis hole of valve rocker workpiece,
It is worthy of popularization.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing:
Referring to attached drawing: it is this to clamp clamp for machining, including lathe supporting rod 1 for workpiece centrifugal force, lathe supporting rod 1
Outer end is fixed with sleeve 2, and the mounting hole 2-1 being laterally arranged is provided on sleeve 2, and resilient sleeve 3 is fixed at mounting hole 2-1, elasticity
Pull rod 4 is installed, the outer end of pull rod 4 cooperates together in male cone (strobilus masculinus) and with the outer end inner conical surface of resilient sleeve 3, pull rod 4 in set 3
Inner end is fixed with platen 5, and the left side of platen 5 is one 5-1 of inclined surface of sharp angle setting, and one 5-1 of inclined surface and lathe press from both sides
It holds and compressed spring 6 is installed between the outer end face of bar 1, be equipped on sleeve 2 and push down the briquetting 7 that platen 5 moves outside, outside sleeve 2
The positioning column 8 of a pair of opposing is fixed on end face, the side of positioning column 8 is equipped with the gag lever post 9 being fixed on sleeve 2.
Shaft 2-2 is fixed on sleeve 2, briquetting 7 is rotatably connected at shaft 2-2, is provided with circle on the contoured surface of shaft 2-2
Arc-shaped slot 2-2a, screw thread is equipped with the positioning screw 10 with arc-shaped card slot 2-2a cooperation, the right side of briquetting 7 on briquetting 7
Two 7-1 of inclined surface of angle setting at an acute angle.
The outside of sleeve 2 is equipped with the cover 11 being fixed on lathe supporting rod 1.
Working principle of the utility model is: the axis hole 12-1 on valve rocker workpiece 12 is mounted at resilient sleeve 2 first,
It is defined by the depth that two positioning columns 8 are nested into resilient sleeve 2 to valve rocker workpiece 12, then, valve rocker workpiece 12
Outer end lean against on gag lever post 9, finally, lathe supporting rod 1 is mounted on lathe, then, lathe drives lathe supporting rod 1 high
Speed rotation, due to the effect of centrifugal force, platen 5 will drive pull rod 4 and press towards 6 side direction of compressed spring, thus, utilize pull rod 4
On male cone (strobilus masculinus) press the inner conical surface in resilient sleeve 3, so that resilient sleeve 3 be made constantly to be flared and be clamped at axis hole 12-1,
