Abstract
The utility model discloses a novel chuck. The novel chuck comprises a chuck body, a movable chuck jaw and a clamping jaw drive mechanism, wherein the movable chuck jaw is radiated outwards by taking the chuck body as a center; and a baffle block is fixed to the top end of the movable chuck jaw and fixed with an 'I'-shaped groove in the movable chuck jaw. A structure that the movable chuck jaw is radiated outwards by taking the chuck body as the center is adopted, and the baffle block is fixed to the top end of the movable chuck jaw at the same time and clamped in the 'I'-shaped groove in the movable chuck jaw through interference fit, so that the baffle block can be dismounted at will to restore the function of the original chuck. Moreover, to solve the problem that a processed workpiece drops in a cutting process due to separation of the movable chuck jaw from the baffle block during high-speed rotation of the chuck, the baffle block is fixed with the 'I'-shaped groove in the movable chuck jaw in a fastening way through a fastening screw. The novel chuck has the advantages of simple structure, convenience for cutting and high processing efficiency.
Description
Technical field
The utility model belongs to the machining tool field of lathe machinery, specifically is a kind of novel chuck.
Background technology
Chuck is to be used for the mechanical device of clamping work pieces on the lathe, is to utilize moving radially of the movable jaw that is distributed on the chuck body, clamps workpiece and the machine tool accessories of location.Chuck generally is made up of chuck body, movable chuck pawl and claw driving mechanism three parts.There is through hole in chuck body central authorities, so that through workpiece or bar; The back has cylindrical or the short taper profile structure, directly or through ring flange and machine tool chief axis end links.Chuck is installed in usually on lathe, cylindrical grinder and the internal grinder and uses, and also can cooperate with various indexing means, is used for milling machine and drilling machine.But during the sky of the chuck work in-process on present lathe workpiece, workpiece moves behind chuck with cutter in the process that is cut, the problem that causes workpiece to come off.
The utility model content
The utility model technical problem to be solved be for solve processing during hollow work-piece workpiece in the process that is cut with cutter move behind chuck that the problem that causes workpiece to come off provides a kind of simple in structure, cut convenient, the novel chuck that working (machining) efficiency is high.
For the technical problem that solves the utility model adopts following technical scheme:
A kind of novel chuck comprises chuck body, movable chuck pawl and claw driving mechanism, said movable chuck pawl with the chuck body be the center to external radiation, a fixing block on said movable chuck pawl top, ' worker ' type groove of said block and movable chuck pawl is fixed.
' U ' type that is shaped as of said block, said block is grabbed in ' worker ' type groove of movable chuck pawl through interference fit.
Fastening fixing in ' worker ' type groove of said block and movable chuck pawl through jackscrew.
The utility model adopt the movable chuck pawl with the chuck body be the center to extraradial structure, a fixing block on the top of movable chuck pawl simultaneously, block is grabbed in ' worker ' type groove of movable chuck pawl through interference fit.Can realize the random dismounting of block like this, recover the function of former chuck.And in order to solve separating of when chuck rotates at a high speed movable chuck pawl and block, make the problem that come off of processing work in working angles, fastening fixing through jackscrew in ' worker ' type groove of block and chuck jaw.The utility model is a kind of simple in structure, cut convenience, the novel chuck that working (machining) efficiency is high.
Description of drawings
Fig. 1 is the utility model structural representation.
Fig. 2 is the utility model block structural representation.
The specific embodiment
Below in conjunction with accompanying drawing the utility model is done further detailed description:
Like Fig. 1, shown in 2, a kind of novel chuck comprises chuck body 5, movable chuck pawl 3 and claw driving mechanism 4.Movable chuck pawl 3 with chuck body 5 be the center to external radiation, a fixing block 2 on movable chuck pawl 3 tops, ' U ' type that is shaped as of block 2.Block 2 is grabbed in ' worker ' type groove of movable chuck pawl 3 through interference fit.Can realize the random dismounting of block like this, recover the function of former chuck.And in order to solve separating of when chuck rotates at a high speed movable chuck pawl 3 and block 2, make the problem that come off of processing work in working angles, fixing in ' worker ' type groove of block 2 and movable chuck pawl 3 through jackscrew fastening 1.
The utility model is through after the simple transformation to common chuck jaws; Be when solving in machining the processing hollow work-piece; Workpiece moves to chuck body 5 back because cutting tool is followed in the effect of external force in the process that is cut together, causes processing work to come off.Adopt movable chuck pawl 3 is that the center is to extraradial structure with chuck body 5 for this reason; Utilize ' worker ' type groove of movable chuck pawl 3; Closely cooperate and go up ' U ' type retaining 2 that is fit to movable chuck pawl 3; And utilize the fastening jackscrew 1 of block 2 sides, tightly be fixed on block 2 top of movable chuck pawl 3.Because block 2 has exceeded the clamping face of movable chuck pawl 3, stopped the approach that workpiece moves to chuck body 5 backs in working angles, thereby made cutting smooth more that efficient is higher.If need not process hollow work-piece simultaneously, can dismantle block 2 at any time, recover other processing request of chuck.
Claims (3)
