Description
Technical field
The utility model belongs to field of mechanical technique, relates to a kind of machine tool chuck special spanner.
Background technology
Along with constantly bringing forth new ideas of science and technology, Machining Technology has also obtained significant progress, and at present, most engineering shops all adopt Computerized Numerical Control processing technology.The machining accuracy of Computerized Numerical Control processing technology is very high, over nearly 10 years, the machining accuracy of regular grade Digit Control Machine Tool is brought up to 5 μ m by 10 μ m, the micron order machining center is then from 3～5 μ m, bring up to 1～1.5 μ m, and Precision of Super-finishing begun to enter nanoscale (0.01 μ m), meanwhile, balance to cutter is also had higher requirement, and the concentricity of cutter and cutter chuck is even more important for the impact of reliability, machining accuracy and the totle drilling cost effect of producing.Cutter chuck generally comprise clamper main body, jaw and with the nut of clamper main body bolt, one end of clamper main body offers a taper hole, jaw can insert in this taper hole, cutter is inserted in the jaw, then screw nut by the cutter chuck special spanner, make jaw firmly grasp cutter because of undergauge, finish processing by Tool in Cutting at last.
China patent CN03219340.8 discloses a kind of Novel milling chuck and spanner thereof, and this chuck comprises taper shank, is provided with the nut of longitudinal fluting, the spring dop, and the face of cylinder of taper shank bottom is provided with radial hole; This spanner comprises handle and tommy bar, described tommy bar semicircular in shape, the radius of semicircle tommy bar is slightly larger than nut, the inboard of tommy bar is evenly equipped with several plush coppers, and the position of plush copper is corresponding with longitudinal fluting, during use, embed plush copper in the groove and tommy bar is close to the face of cylinder of nut, firmly pull several times and just nut can be screwed, the tommy bar semicircular in shape of this spanner can slippage when pulling nut.
But, because nut is threaded connection on clamper main body, have larger gap in the helicitic texture, above-mentioned spanner is when screwing nut, and the operator only exerts oneself in one direction, when the angle of operator's application of force or size are held when bad, nut can be subject to larger power radially, thereby relative clamper main body generation radial disbalance swings cutter, reduce the concentricity of cutter and cutter chuck, directly affect the service life of mechanical processing quality and lathe.Simultaneously because the chuck clamping is tighter, semi-circular spanner is in unloading the cutter process, general both hands at same directional lever firmly, when the groove on the chuck skids because of wearing and tearing or chuck when relaxing suddenly, operating personnel's health can be tumbled or sliding steps easily because of the inertia disequilibrium, and operational danger is larger, and above-mentioned spanner whenever reverses half-turn and just need again overlap upper groove and repeat to reverse, and handling procedure is more loaded down with trivial details.
Summary of the invention
The purpose of this utility model is the problems referred to above that exist for existing technology, and a kind of special spanner of machine tool chuck is provided, the concentricity of cutter and cutter chuck when technical problem to be solved in the utility model is the raising Cutting tool installation manner.
The purpose of this utility model can realize by following technical proposal: a kind of special spanner of machine tool chuck, this spanner comprises spanner one, the spanner two that can mutually make up, can be socketed on the cutter chuck after described spanner one and spanner two combinations, and described spanner one and spanner two inboards are equipped with and can make spanner one, spanner two and the location structure that cutter chuck rotates synchronously, are fixed with respectively handle one, handle two on described spanner one, the spanner two.
With spanner one, spanner two is socketed on the cutter chuck, make spanner one, spanner two can rotate synchronously with cutter chuck, then distinguish control handle one about both hands, handle two turn cutter chucks, can finish evenly the fastening of cutter or dismounting, nut on the cutter chuck is difficult for occuring radial deflection, thereby avoid cutter to swing, improve the concentricity of cutter and cutter chuck, and because both hands are at handle one, application of force direction is different on the handle two, when the groove on the chuck skids because of wearing and tearing or chuck when relaxing suddenly, operating personnel's health can because of the inertia disequilibrium, not reduce operating personnel's operational danger.
In the special spanner of above-mentioned a kind of machine tool chuck, described spanner one and spanner 21 ends are hinged, and the other end is respectively arranged with one and has contact with and hasp, in described hasp can be buckled in and have contact with.By hasp and cooperatively interacting of having contact with, spanner one, spanner two are joined end to end mutually, and connect and dismantle all easily, tightness is strong.
In the special spanner of above-mentioned a kind of machine tool chuck, as another kind of scheme, described spanner one and spanner two two ends are respectively arranged with has contact with and hasp, and described hasp can be buckled in having contact with of another spanner.By hasp and cooperatively interacting of having contact with, spanner one and spanner two are removably connected, when damaging appearred in spanner one or spanner two, then a fast changeable wherein spanner reconfigured connection and gets final product, spanner easy to maintenance.
In the special spanner of above-mentioned a kind of machine tool chuck, described handle one, handle two inner ends are connected with spanner one, spanner two respectively, and the outer end of handle one, handle two is provided with a curve-like grip part.After being provided with the curve-like grip part, the handled easily personnel control spanner, prevent spanner landing in the operating process.
In the special spanner of above-mentioned a kind of machine tool chuck, be provided with a rocking arm on described handle one or the handle two.In dismounting during cutter, after spanner one, spanner two are socketed on the cutter chuck, can reverse consistently by rocking arm until unload bottom tool, and conventional spanner is whenever reversed half-turn and just need be unloaded lower ejector lever and again be socketed complex procedures always.
In the special spanner of above-mentioned a kind of machine tool chuck, described location structure comprises the projection that several are installed in spanner one, spanner two inboards and can match with the recess on the cutter chuck outer peripheral face.Projection on spanner one, the spanner two is plugged in the recess on the cutter chuck outer peripheral face, can spanner one, spanner two is circumferentially fixing with cutter chuck, the three can be rotated synchronously.
In the special spanner of above-mentioned a kind of machine tool chuck, as another kind of scheme, described location structure comprises the recess that several are installed in spanner one, spanner two inboards and can match with the protuberance on the cutter chuck outer peripheral face.The recess of spanner one, spanner two inboards is socketed on the protuberance on the cutter chuck outer peripheral face, spanner one, spanner two are rotated synchronously with cutter chuck.
Compared with prior art, the utlity model has following advantage:
1, this spanner is when the turn cutter chuck, and making a concerted effort that cutter chuck directly upwards is subject to is less, and the nut on the cutter chuck is difficult for radial deflection occurs, thereby avoids cutter to swing, and improves the concentricity of cutter and cutter chuck.
2, this spanner can prevent from operating personnel's operating process skidding or suddenly absent-mindedness of chuck causes falling because of the wearing and tearing of the groove on the chuck, reduces operating personnel's operational danger.
3, this spanner can reverse by rocking arm in unloading the cutter process until unload bottom tool always consistently, and is swift to operate simple.
