Abstract
The utility model discloses a lever-type floating claw chuck mechanism, which belongs to the technical field of machine tools, and comprises a slide block capable of sliding in a chuck, a lever hinged on a machine tool, and a movable pulling plate, wherein one end of the lever is movably connected with the slide block in a clamping way; and a movable shaft is arranged on the other end of the lever in an inserting way, and is hinged with the pulling plate.
Description
Technical field
The utility model relates to the unsteady dog chuck mechanism of a kind of lever, belongs to the machine tool technology field.
Background technology
At present, what mostly use on the lathe is self-centering chuck, and self-centering chuck needs slide block to move simultaneously, is unfavorable for clamping eccentric work piece and irregular workpiece, and can the power of radially oppressing be arranged to thimble during the self-centering chuck clamping work pieces, causes deviations.
Summary of the invention
The purpose of this utility model is the defective that overcomes prior art, provide a kind of simple in structure, do not need slide block to operate simultaneously and the lever of the accurate positioning dog chuck mechanism of floating.
The technical scheme that realizes the utility model purpose is: a kind of lever dog chuck mechanism of floating, comprise the slide block that can in chuck, slide, also comprise the lever that is hinged on the lathe and arm-tie movably, one end of lever and slide block activity clamping, the other end of lever is fitted with shifting axle, and this shifting axle and arm-tie are hinged.
Further, an end of described lever has shifting block, is provided with the slot of joining with the shifting block cunning on the described slide block.
After having adopted technique scheme, when arm-tie stressed during to left movement, shifting axle will force lever to do clockwise rotation, the lever other end will move downward, thereby so that slide block moves downward, so that slide block clamping work pieces, in like manner, when arm-tie is stressed when moving right, shifting axle will force lever to be done and be rotated counterclockwise motion, the lever other end will move upward, thereby so that slide block moves upward, so that slide block unclamps workpiece, realize whole clamping and the operation of unclamping workpiece, used chuck of the present utility model need to not operate simultaneously by the slide block on chuck, can single slide block movement, as long as the independent to the left or to the right motion of each arm-tie can be realized, clamp easily eccentric work piece, and the utility model do not promote arm-tie with radial load, avoided to a certain extent the position error that radially the oppressing power of thimble caused.
Description of drawings
Fig. 1 is the structural representation of the unsteady dog chuck mechanism of lever of the present utility model.
The specific embodiment
Content of the present utility model is easier to be expressly understood in order to make, and the below is described in further detail the utility model according to specific embodiment also by reference to the accompanying drawings,
As shown in Figure 1, a kind of lever dog chuck mechanism of floating, comprise the slide block 1 that can in chuck, slide, also comprise the lever 2 that is hinged on the lathe and arm-tie 3 movably, one end of lever 2 and slide block 1 activity clamping, the other end of lever 2 is fitted with shifting axle 4, this shifting axle 4 by ship and resell on another market 6 with arm-tie 3 hinged.One end of lever 2 has shifting block 2-1, is provided with the sliding slot 1-1 that joins with shifting block 2-1 on the slide block 1.
Lever 2 can be shipped and resell on another market with lever and 5 is connected on the lathe, makes itself and lathe hinged.
Operation principle of the present utility model is as follows:
When arm-tie 3 stressed during to left movement, shifting axle 4 will force lever 2 to do clockwise rotation, lever 2 other ends will move downward, thereby so that slide block 1 moves downward, so that slide block 1 clamping work pieces, in like manner, when arm-tie 3 stressed moving right, shifting axle 4 will force lever 2 to be done and be rotated counterclockwise motion, and lever 2 other ends will move upward, thereby so that slide block 1 move upward, so that slide block 1 unclamps workpiece, realize whole clamping and the operation of unclamping workpiece, used chuck of the present utility model need to not operate simultaneously by the slide block 1 on chuck, can move by single slide block 1, as long as each arm-tie 3 independent to the left or to the right motion can be realized, clamp easily eccentric work piece, and the utility model has been avoided the position error that radially the oppressing power of thimble caused to a certain extent with radial load promotion arm-tie 3.
Above-described specific embodiment; the purpose of this utility model, technical scheme and beneficial effect are further described; institute is understood that; the above only is specific embodiment of the utility model; be not limited to the utility model; all within spirit of the present utility model and principle, any modification of making, be equal to replacement, improvement etc., all should be included within the protection domain of the present utility model.
