Abstract
A chuck rotational insurance mechanism includes a pull rod which is connected with an oil cylinder, a cutting sleeve which is connected with the chuck and a bolt which connects the pull rod with the cutting sleeve. The utility model is characterized in that a slide bushing which is sleeved on the bolt is arranged between the pull rod and the cutting sleeve; the slide bushing is axially equipped with a spring and a steel ball and radially equipped with a tightly fixed bolt; the end face of the cutting sleeve and the corresponding position of the steel ball are provided with pits. The utility model is used for clamping and loosening the hydraulic pressure chuck of the machine tool; in case of appearing the phenomenon of inflexible rotation of the piston bearing or dead obstruction in the oil cylinder, the torque will be increased; the steel ball will slip and the pull rod will not rotate along with the chuck in order to avoid the accidents.
Description
Technical field
The utility model relates to a kind of oild chuck that is used for and clamps or unclamp, prevent stuck chuck rotation insurance institution.
Background technology
The oild chuck that is used for clamping workpiece in the machining apparatus is stirred by the claw of slip cutting ferrule and is realized clamping or unclamping, and the slip cutting ferrule then is connected with pull bar by screw usually, pull bar under the drawing cylinder driving to the right or be moved to the left.There is following defective in existing this mechanism: just in case the dumb or stuck phenomenon of piston bearing rotation appears in the drawing cylinder, and the slip cutting ferrule continues rotation with chuck, will cause damage of components, causes the accident.
The utility model content
The technical problems to be solved in the utility model provides a kind of chuck safe, reliable, accident prevention and rotates insurance institution.
The technical solution of the utility model is: chuck rotation insurance institution, the screw that comprises the pull bar that links to each other with drawing cylinder, the slip cutting ferrule that links to each other with oild chuck and cylinder lever connecting rod, cutting ferrule, improvements are to be provided with the sliding sleeve that is sleeved on the screw between pull bar and the slip cutting ferrule, the sliding sleeve upper edge is axially arranged with spring and steel ball, radially be provided with holding screw, the corresponding position of slip cutting ferrule end face and steel ball is provided with pit.
Above-mentioned pit is 3～6, is distributed on the same circumference of slip cutting ferrule end face.
Be provided with sliding sleeve in the utility model between pull bar and slip cutting ferrule, sliding sleeve and screw fix, and the steel ball on the sliding sleeve falls into the pit of cutting ferrule end face at spring pressure, during assembling, control the pretightning force of screw well, when piston bearing in the oil cylinder rotates when flexible, chuck drives pull bar and rotates smoothly, when the piston bearing rotation is dumb or stuck in the oil cylinder, moment of torsion increases, and then steel ball skids off pit and skids at the cutting ferrule end face, and pull bar is not rotated with chuck, try to avert accidents, play safety effect.
Description of drawings
Accompanying drawing is the utility model structural representation.
The specific embodiment
As figure, the pull bar 2 that links to each other with drawing cylinder 1, with slip cutting ferrule 8 that oild chuck 9 links to each other between be provided with sliding sleeve 4, connect by screw 3 jointly, the sliding sleeve upper edge is axially arranged with spring 5 and steel ball 7, radially be provided with spiral shell and decide screw 6, slip cutting ferrule 8 end faces and the corresponding position of steel ball are provided with 6 circumferential uniform pits.
Claims (2)
1, a kind of chuck rotates insurance institution, the screw that comprises the pull bar that links to each other with drawing cylinder, the slip cutting ferrule that links to each other with oild chuck and cylinder lever connecting rod, cutting ferrule, it is characterized in that being provided with the sliding sleeve that is sleeved on the screw between pull bar and the slip cutting ferrule, the sliding sleeve upper edge is axially arranged with spring and steel ball, radially be provided with holding screw, the corresponding position of slip cutting ferrule end face and steel ball is provided with pit.
2, by the described chuck rotation of claim 1 insurance institution, it is characterized in that described pit is 3～6, be distributed on the same circumference of slip cutting ferrule end face.
