A kind of clamping tool for machine work of steady type band storage cotter way
Technical field
The utility model relates to a kind of mechanical clamping apparatus technical field, particularly a kind of clamping tool for machine work of steady type band storage cotter way.
Background technology
Fixture refers to and be used for fixing processing object in machine-building process, makes its clamping in the position of the best, allows workpiece accept construction or to detect.On lathe during processing work, the dimensions reaching drawing for making the surface of workpiece and specify, geometry and with the technical requirements such as the relative-position error on other surfaces, workpiece must be installed (location) before processing, clip (clamping).
Fixture of the prior art is when clamping workpiece to be machined, owing to clamping shakiness, easy generation is tilted or shift phenomenon, some hollow workpiece has iron filings and gets in the squeezing groove of chuck in the process of processing, damage squeezing groove, affect operating efficiency, improve maintenance probability, reduce the precision of converted products, at some ring-shaped work pieces of processing, particularly bearing, utilize general fixture or hanger to use inconvenient, positioning precision is not high, affects Workpiece Machining Accuracy, be easy to the end face of axle sleeve to be processed to weigh wounded, have impact on the quality of axle sleeve processing.
Utility model content
Goal of the invention of the present utility model is: for prior art Problems existing, provides a kind of steady type band to store up the clamping tool for machine work of cotter way.
To achieve these goals, the technical solution adopted in the utility model is: a kind of clamping tool for machine work of steady type band storage cotter way, comprise base and be arranged on the chuck on base, described chuck is bolted to connection on base, described chuck has elasticity, the head exterior surface of described chuck is provided with draw-in groove, the center of described chuck is provided with installation squeezing groove, described installation squeezing groove lower end is provided with storage cotter way, described installation squeezing groove inwall is provided with cushion, described cushion inwall is also provided with promptly stratum granulosum, is provided with cushion pad between described chuck and base.
As preferred version of the present utility model, described squeezing groove is radial slot or conical hole slot cylindrical hole groove or cuboid hole slot.
As preferred version of the present utility model, described draw-in groove is a cannelure or is two, three, four unit grooves.
As preferred version of the present utility model, the material of described cushion is for having flexible rubber.
As preferred version of the present utility model, described storage cotter way is circular or rectangle or ellipse.
As preferred version of the present utility model, the material of described chuck is iron or stainless steel.
Owing to have employed technique scheme, the beneficial effects of the utility model are: be provided with cushion pad between chuck and base, can well reduce the hard friction between chuck and base, reduce wear, and improve service life; When processing annular bearing, squeezing groove on collet provides enough spaces, only need by collet interior extruding mutually during use, ring-shaped work pieces just can be set in the draw-in groove on collet, and the elasticity of collet isomorphism self can restPose, now, part would not landing chuck, the round diameter that part is formed after being set on draw-in groove is greater than the maximum gauge of collet, is adding man-hour, and machine can be good at processing parts and can not damage chuck itself; When the annular workpieces that processing dimension is less, the squeezing groove if the iron filings produced are entered, can call in storage cotter way, need not stop lathe, processing can be continued, also can not defective work piece, cushion also can allow the clamping of workpiece firm, and promptly particle is more firm by the clamping of workpiece, this structure is simple, clamping is firm, easy to operate, substantially increases crudy and the working (machining) efficiency of part.
