The utility model solves the technical scheme that its technical problem adopts: a kind of drum self-centering fixture of drum type lathe, comprise fluid pressure drive device and self-centering clamping device, self-centering clamping device comprises symmetrical two gripper clamps, symmetrical two clamp lever, straight pin, tie rod and mount pad, two gripper clamps are arranged on mount pad by track structure symmetrically, on gripper clamp, there is V-type jaws, two gripper clamps drive by clamp lever, slippage relatively, clamp, discharge workpiece, two clamp lever are arranged on mount pad by rotating shaft symmetrically, one end of clamp lever drives and coordinates with the gripper clamp of homonymy, on another swinging end of clamp lever, there is slotted eye, straight pin passes the slotted eye of two clamp lever simultaneously, tie rod is arranged on mount pad, one end of tie rod is connected with straight pin, the other end of tie rod is connected with fluid pressure drive device.
Further limit, on one end of clamp lever, have the shifting block of stirring gripper clamp slippage, shifting block top has curved working face, has the allocating slot matching with shifting block in the bottom of gripper clamp, shifting block embeds allocating slot, and clamping lever and gripper clamp are driven and coordinated by shifting block and allocating slot.
Further limit, straight pin middle part has screwed hole, and screwed hole is mutually vertical with the axis of straight pin, and tie rod is threaded by screwed hole with straight pin.
Further limit, self-centering clamping device has two, two self-centering clamping devices are separately positioned on the both sides of fluid pressure drive device, fluid pressure drive device comprises oil cylinder and bell crank lever, respectively there is a piston rod both sides of oil cylinder, and piston rod promotes the self-centering clamping device of the same side relative mount pad of tie rod by bell crank lever moves up and down.
The beneficial effects of the utility model are: adopt hydraulic clamp can obtain enough clamping forces, and the physical dimension of this fixture is relatively very little, and noise is little, is applicable to very much the processing of many specifications axial workpiece.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated;
Fig. 1 is the structural representation of self-centering clamping device of the present utility model;
Fig. 2 is overall structure schematic diagram of the present utility model;
Wherein, 1. gripper clamp, 2. clamp lever, 3. straight pin, 4. tie rod, 5. mount pad, 6. oil cylinder, 7. bell crank lever, 8. workpiece.
The specific embodiment
As illustrated in fig. 1 and 2, a kind of drum self-centering fixture of drum type lathe, comprise fluid pressure drive device and self-centering clamping device, self-centering clamping device comprises symmetrical two gripper clamps 1, symmetrical two clamp lever 2, straight pin 3, tie rod 4 and mount pad 5, two gripper clamps 1 are arranged on mount pad 5 symmetrically by track structure, on gripper clamp 1, there is V-type jaws, two gripper clamps 1 drive by clamp lever 2, slippage relatively, clamp, discharge workpiece 8, two clamp lever 2 are arranged on mount pad 5 symmetrically by rotating shaft, one end of clamp lever 2 drives and coordinates with the gripper clamp of homonymy 1, on another swinging end of clamp lever 2, there is slotted eye, straight pin 3 passes the slotted eye of two clamp lever 2 simultaneously, tie rod 4 is arranged on mount pad 5, one end of tie rod 4 is connected with straight pin 3, the other end of tie rod 4 is connected with fluid pressure drive device.
On one end of clamp lever 2, have the shifting block of stirring gripper clamp 1 slippage, shifting block top has curved working face, has the allocating slot matching with shifting block in the bottom of gripper clamp 1, and shifting block embeds allocating slot, and clamping lever and gripper clamp 1 are driven and coordinated by shifting block and allocating slot.
Self-centering clamping device has two, two self-centering clamping devices are separately positioned on the both sides of fluid pressure drive device, fluid pressure drive device comprises oil cylinder 6 and bell crank lever 7, respectively there is a piston rod both sides of oil cylinder 6, and the relative mount pad 5 of tie rod 4 that piston rod promotes the self-centering clamping device of the same side by bell crank lever 7 moves up and down.
Workpiece kind to be processed reaches 9 kinds, and diameter from 25.23mm to 28.65mm not etc., adopts self-centering location clamping mode can guarantee that the center that adds workpiece in man-hour remains unchanged, in addition, due to because working (machining) efficiency is high, to the wearing and tearing of fixture, can accelerate, self-centering form can guarantee that workpiece centre is constant.
The course of work is as follows:
Holding workpiece 8: the piston rod of oil cylinder promotes tie rod 4 by bell crank lever 7 and moves down, tie rod 4 drives clamp lever 2 to swing by straight pin 3 simultaneously, thereby drive the simultaneously inside move toward one another of two gripper clamps 1, because two jaws are V-structure, so can make during clamping work pieces 8 workpiece 8 realize centering; Because left and right two clamp lever 2 are measure-alike, and driven by straight pin 3 simultaneously, thereby can guarantee that the distance that two of left and right gripper clamp 1 moves equates, can guarantee that like this variation of workpiece 8 diameters can not change the position at workpiece 8 centers, thereby realize self centering function.
Discharge workpiece 8: the piston rod of oil cylinder promotes to move on tie rod 4 by bell crank lever 7, tie rod 4 drives clamp lever 2 to swing by straight pin 3 simultaneously, thereby drives the 1 outside opposing motion simultaneously of two gripper clamps, thereby discharges workpiece 8.
