The high-speed machining clamping device of the lathe is high in machining efficiency and low in machining cost.
Description
Technical field
The present invention relates to a kind of lathe High-speed machining clamping device.
Background technology
Lathe main is wanted working shaft-like, dish class and rotary part. Existing lathe is to process after using scroll chuck or chuck clamping workpiece. Existing three-jaw or four paws one are that chuck clamping point is few, the 2nd, and blade tooth moves radially clamping, and rotary speed is faster, and centrifugal force is larger, and clamping force is less, is difficult to carry out workpiece processing under High Rotation Speed state, or is also difficult to reach machining accuracy under higher speed. If processed under low speed rotation state, working (machining) efficiency is low, and processing cost is high.
Summary of the invention
The object of the invention is the weak point for existing clamping apparatus for lathe, a kind of lathe processing clamping device of processing under fast state and ensureing machining accuracy is provided.
The present invention is achieved in that packaging base, spring clamp, hydraulic thrust pull system, it is characterized in that base comprises clamp base 5, positioning support support set 4, gripping sleeve 3, positioning support support set 4 is located by connecting by seam and gripping sleeve 3 above, fastening with screw 2, the inwall of gripping sleeve 3 is conical surface B, the axle center of conical surface B just with the axis coinciding of main shaft 9, positioning support support set 4 is located by connecting below by seam and clamp base 5, fastening with screwing 11, clamp base 5 is located by connecting by seam and main shaft 9, fastening with lower screw 8, spring clamp system is housed in base, spring clamp system comprises spring clamp cover 6, pulling plate 13, spring clamp cover 6 is arranged in pulling plate 13, locate with spring collar 7, the blade tooth of spring clamp cover 6 is 4～18, the outer wall on blade tooth top is conical surface A, the axle center of conical surface A just with the axis coinciding of main shaft 9, conical surface A is identical with the tapering of conical surface B, hydraulic thrust pull system comprises hydraulic gyration oil cylinder 10, pull bar 14, hydraulic thrust pull system is installed on main shaft 9, pull bar 14 is connected with pulling plate 13 use central screws 12 through the centre bore of main shaft 9, pull bar 14 lower ends are connected with hydraulic gyration oil cylinder 10, hydraulic gyration oil cylinder 10 is arranged on the lower end of main shaft 9.
The present invention is before clamping workpiece 1, hydraulic gyration oil cylinder 10 pushing drawing rods 14 travel forward, make spring clamp cover 6 in natural open configuration, workpiece 1 is positioned on the locating surface of positioning support support set 4, then hydraulic gyration oil cylinder 10 pulls pull bar 14 to move backward, pulling plate 13 drives spring clamp cover 6 motion backward, spring clamp cover 6 is shunk by the inside power generation strain of gripping sleeve 3, workpiece 1 support set 4 restriction that is positioned cannot be moved simultaneously backward, thereby spring clamp cover 6 continues motion backward, workpiece 1 is clamped.
Clamping point of the present invention is many, chucking power is evenly distributed, workpiece is not easy distortion, the conical surface B axle center of gripping sleeve 3 of the present invention overlaps with spindle axis, the axle center of the conical surface of inboard wall B of gripping sleeve 3 and the axis coinciding of main shaft 9, conical surface A is identical with the tapering of conical surface B, spring clamp cover 6 is in gripping sleeve 3, under the state of High Rotation Speed, owing to being subject to hydraulic thrust pull system pull bar 14 pulling force and the inside power of gripping sleeve 3, the clamping force of spring clamp cover 6 is remained unchanged, thereby realize processing work under High Rotation Speed state. Can realize self-centering because of spring clamp cover 6 at High Rotation Speed state again and clamp, can effectively ensure machining accuracy. The present invention is applicable to the workpiece of processing clamping diameter from 50mm to 1000mm. Use invention working (machining) efficiency high, processing cost is low.
