Description
Technical field
The present invention relates to a kind of fixture, especially relate to a kind of for the fixture on slow wire feeding lathe.
Background technology
In the use procedure of slow wire feeding lathe, sometimes need the workpiece of processing circle or similar circle, so just need to there is the fixture that can clamp this workpiece.At present, on market, general fixture is all to adopt the directly mode of docking of two V-blocks, the frictional force and the centering force clamping work pieces that utilize the clamping force between V-block and workpiece to produce, this fixture can be used for clamping most of circle or be similar to circular workpiece, but while running into the larger workpiece of large-scale workpiece or quality, because of required frictional force larger, in clamping process, just require V-block to apply very large clamping force to workpiece, easily cause excessive deformation or the surface damage of workpiece, affect line cutting processing precision.Meanwhile, owing to being that line contacts between V-block and workpiece, contact area is little, and between V-block and workpiece, frictional force only depends on increase chucking power to provide, and so also can shorten the life-span of fixture.
Chinese patent CN202398915U has announced a kind of fixture for slow feeding linear cutting, comprising: a side component of the fixture being connected with platen; Two locating holes are set on a described side component; Also comprise the opposite side parts of the fixture of workpiece placement platform; On four angles of opposite side parts of described fixture, settle 4 fasteners; At the other hexagon socket head cap screw of settling of side of described each fastener; The fastening described workpiece of described hexagon socket head cap screw.This patent has solved a clamping difficult problem, but this clamp structure is comparatively complicated, and the scope of application is narrower.
Summary of the invention
Object of the present invention be exactly provide in order to overcome the defect that above-mentioned prior art exists a kind of simple in structure, easy to use, the scope of application is wide for the fixture on slow wire feeding lathe.
Object of the present invention can be achieved through the following technical solutions:
A kind of for the fixture on slow wire feeding lathe, comprise fixed claw and movable claw, described fixed claw comprises the gripper shoe for supporting workpiece, be located at the first clamping limb in gripper shoe, and the fixed arm being wholely set with the first clamping limb, described fixed arm is provided with gathering sill, the rear side of this gathering sill is provided with through hole, in this through hole, be provided with bolt, the travelling arm that described movable claw comprises the second clamping limb and is connected with the second clamping limb, this travelling arm is inserted in gathering sill, and be connected with the bolt being located in through hole, pass through swivel bolt, travelling arm is slided in gathering sill, make the second clamping limb to the close also clamping work pieces of the first clamping limb.Gathering sill plays and supports and guide effect for travelling arm.
In described travelling arm, offer the bolt hole being connected with bolt thread.
Vertical connection between the first described clamping limb and fixed arm, vertical connection between the second described clamping limb and travelling arm.
The first described clamping limb and the inner side of the second clamping limb are screwed flexible gasket, and flexible gasket plays increasing friction force and reduces the effect of workpiece damage.
Described flexible gasket is rubber sheet gasket.
The first described clamping limb is all offered two planes for being connected with the inner side of the second clamping limb, and the angle of two planes is between 90～180 °.
Offer as circular arc for one jiao of described gripper shoe.
Described fixed arm is provided with for fixed claw being fixed on to the installing hole on slow wire feeding platen.
During by this fixture holding workpiece, first workpiece is placed in the gripper shoe of fixed claw, then slow circumvolve bolt makes the second clamping limb move to the first clamping limb, until the second clamping limb and the first clamping limb clamp and centering workpiece.This fixture can clamping work pieces scope be diameter 100～135mm.
Compared with prior art, the present invention has the following advantages and beneficial effect:
(1), while clamping the larger workpiece of quality, because there is the holding power of gripper shoe, so do not need very large clamping force to carry out clamping work pieces, this has reduced unnecessary workpiece surface damage and excessive deformation to a certain extent.
(2) because the inner side of the first clamping limb and the second clamping limb is provided with flexible gasket, contacting between the first clamping limb and the second clamping limb and workpiece is face contact, less chucking power just can produce larger frictional force, workpiece deformation is less, in addition, owing to not being rigidity contact, the surface damage of workpiece is also less.
(3) clamp structure of the present invention is simple, easy to use, applicable to the clamping of diameter 100～135mm workpiece.
