Specific implementation mode
Explanation and specific implementation mode further illustrate the utility model below in conjunction with the accompanying drawings.
As shown in Figures 1 to 12, a kind of drilling tool spear-head clamping device comprising shaft 1 and ratchet drive mechanism 2,
Cam ball mechanism 3, the ratchet drive mechanism 2, Cam ball mechanism 3 are sheathed on respectively in shaft 1, inside the shaft 1
Equipped with the blind hole 11 for accommodating spear-head, spear-head 4 is placed in blind hole 11,2 driving cam ball of the ratchet drive mechanism
Mechanism 3 locks or unclamps spear-head 4.
Specifically, as shown in Figures 1 to 12,1 lower part of the shaft is equipped with base frame 12, and the shaft 1 is at base frame 12
Equipped with the conical through-hole 13 for accommodating ball, the aperture at the addendum cone of the conical through-hole 13 is less than the diameter of ball, in this way
Ball is unlikely to fall into blind hole 11, and the addendum cone hole of the conical through-hole 13 is connected to blind hole 11;The Cam ball mechanism 3 is wrapped
Ball 31, ball 32, elastic element 33, axis pin 34 are included, is equipped in bigger than hole size in 32 hole of the ball
Collar aperture 321,32 side wall of the ball are equipped with guide groove 322, and the inner ring hole 321 and the endoporus of ball 32 use song
Face or conical surface connection, 32 top of the ball are equipped with cam 323, and the ball 31 is positioned in conical through-hole 13, described
The loosening of ball 32 is sheathed on outside shaft 1, and the loosening of the elastic element 33 is sheathed on outside ball 32 and elasticity presses on
Between 323 bottom of cam and base frame 12, the axis pin 34 is fixedly installed in shaft 1 and is in axial sliding connection with guide groove 322,
The axis pin 34 and guide groove 322 limit ball 32 and can only slide axially along about 1 shaft;The ball 32 is downward
Movement, the endoporus of the ball 32 force 31 fraction of ball to protrude taper with the connection curved surface of inner ring hole 321 or the conical surface
Through-hole 13 is to block spear-head 4;Otherwise ball 32 moves upwards, endoporus and the inner ring hole 321 of ball 32
Curved surface or the conical surface are connected far from ball 31, then ball 31 downwardly and outwardly moves away from out along conical through-hole 13 under gravity
Spear-head 4, to unclamp spear-head 4.The elastic element 33 is spring.The quantity of the ball 31 and conical through-hole 13
Identical is all 2 to 12.The ball 31 of the utility model and the quantity of conical through-hole 13 are all 6.
Specifically, as shown in Figures 1 to 12,1 top of the shaft is equipped with guide part 14, and the ratchet drive mechanism 2 wraps
Actuating sleeve 21, driven set 22, driving wheel 23, driven wheel 24 are included, the actuating sleeve 21 is internally provided with pilot hole 211, the driving
It covers 21 lower parts and is equipped with drive pin 212,22 lower parts of the driven set are equipped with skewed slot 221, the skewed slot 221 and 22 outer wall shapes of driven set
Angled, 23 bottom of the driving wheel is equipped with many serrations 231, and 24 top of the driven wheel also is provided with many serrations
231,24 bottom of the driven wheel sets the double wedge 241 there are two symmetric design, and the double wedge 241 is contacted with 323 circumferential surface of cam;Institute
It states the loosening of driven wheel 24 and is sheathed on that shaft 1 is outer and two symmetrical double wedges 241 are placed on cam 323,22 loosenings of driven set
It is sheathed on outside driven wheel 24 and cam 323, the loosening of the driving wheel 23 is sheathed on outside shaft 1 and is fixedly connected as with driven set 22
Integral structure, the loosening of the actuating sleeve 21 are sheathed on outside driven set 22, and the drive pin 212 coordinates with the driving of skewed slot 221, described
Guide part 14 and 211 axially directed cooperation of pilot hole, the serration 231 of 23 bottom of the driving wheel with it is thin at the top of driven wheel 24
Sawtooth 231 can be engaged;When the actuating sleeve 21 moves downward, the drive pin 212 act on skewed slot 221 power can be analyzed to
Lower axial force makes driving wheel 23 and driven wheel 24 tightly engage and be integrally formed with rotation peripheral force, axially downwards power, revolves simultaneously
Turning peripheral force drives driving wheel 23 and driven wheel 24 to rotate together with, and drives two symmetrical double wedges 241 of driven wheel 24 in cam
It is circumferentially slided on 323 faces, to make ball 32 be moved downward along shaft 1;When otherwise actuating sleeve 21 moves upwards, the drive
The power that dynamic pin 212 acts on skewed slot 221 can be analyzed to axially upwardly power and the circumferential counter-force of rotation, and axially upwardly power makes driving wheel
23 and driven wheel 24 unclamp, circumferential counter-force do not work to driven wheel 24, under the effect of spring force to ball 32
It is moved upwards along shaft 1.Jig saw at the top of actuating sleeve 21, driven set 22, the serration 231 of 23 bottom of driving wheel and driven wheel 24
Tooth 231 constitutes a kind of ratchet mechanism.Cam 323, driven wheel 24 two symmetrical double wedges 241, elastic elements 33 constitute
A kind of cam mechanism.Since the hole size of ball 32 is smaller than the size of inner ring hole 321, it is radial that ball 31 can be generated in this way
It is elastic, relative to the installation site of ball 31, when ball 31 slides into the small position in aperture of ball 32, ball
Ball 31 is pressed into the conical through-hole 13 of ball 32 by 32 hole inner walls, because ball 31 protrudes the endoporus of shaft 1 so that shaft
1 internal diameter becomes smaller, and blocks spear-head 4 in this way, prevents it from exiting；When the aperture that ball 31 slides into ball 32 is big
When position, ball 31 can exit 13 certain size of conical through-hole, i.e., do not influence the diameter of 1 endoporus of shaft, such spear-head 4 can
Freely to stretch into and exit.21 head of actuating sleeve is additionally provided with draw ring, because actuating sleeve 21 uses rope traction, when spear-head 4
When fixed, the power of ball 32 is ultimately derived from the dead weight of actuating sleeve 21.
The operation principle of the utility model：When the actuating sleeve 21 moves downward, the drive pin 212 acts on skewed slot
221 power can be analyzed to power axially downwards and rotation peripheral force, and power makes driving wheel 23 and driven wheel 24 closely nibble axially downwards
Synthesis is integrated, while rotating peripheral force and driving wheel 23 and driven wheel 24 is driven to rotate together with, and drives two of driven wheel 24 right
The double wedge 241 of title circumferentially slides on 323 face of cam, to make ball 32 be moved downward along shaft 1, the ball
32 endoporus forces 31 fraction of ball to protrude conical through-hole 13 and is salvaged to block with the connection curved surface of inner ring hole 321 or the conical surface
Spearhead 4;When otherwise actuating sleeve 21 moves upwards, the power that the drive pin 212 acts on skewed slot 221 can be analyzed to axially upwardly power
With the circumferential counter-force of rotation, axially upwardly power driving wheel 23 and driven wheel 24 are unclamped, circumferential counter-force does not act as driven wheel 24
With, to which ball 32 is moved upwards along shaft 1 under the effect of spring force, the endoporus and inner ring hole of ball 32
321 connection curved surface or the conical surface are downwardly and outwardly moved along conical through-hole 13 under gravity far from ball 31, then ball 31
Spear-head 4 is kept away from, to unclamp spear-head 4.
The utility model has the advantage of the utility model is locked using 3 driving cam ball bearing mechanism 2 of ratchet drive mechanism
Or unclamp spear-head 4.The utility model is simple in structure, at low cost, underwater operation is convenient, clamp, unclamp it is easy to operate, can
It leans on.
It, cannot the above content is specific preferred embodiment further detailed description of the utility model is combined
Assert that the specific implementation of the utility model is confined to these explanations.For the ordinary skill of the utility model technical field
For personnel, without departing from the concept of the premise utility, a number of simple deductions or replacements can also be made, should all regard
To belong to the scope of protection of the utility model.
