Description
Technical field
It the utility model is related to a kind of machining fixture, and in particular to receipts formula fixture in one kind.
Background technology
In the process of engineering goods, it is often necessary to the product being not yet molded is processed with Digit Control Machine Tool,
, it is necessary to which product to be processed is positioned and clamped during Digit Control Machine Tool is processed.In actual processing pump cover（Such as figure
Pump cover shown in 1）During, current existing fixture is fixture as shown in Figures 2 and 3, and the fixture is by numerical control chuck a and three
Pawl b form, by numerically controlled lathe oil pressure drive three-jaw b pump cover c to be processed is loosened or clamped, but the fixture exist it is following
Deficiency：
1. because the irregular of profile of pump cover product results in adding man-hour requirement to be repeatedly processed.Three-jaw is on chuck
The fixture of 120 degree of deciles, External Shape irregularly can not normal holding parts, and the 1000- that run at high speed on lathe
1200 revs/min, come as the uneven high-speed rotation of part stress can cause part to fly out.
2. product bite gradient is larger to easily cause product loosening in processing, easily accidents happened.
It cannot be guaranteed 3. bite makes machined surface be easily deformed dimensional accuracy close to machined surface.
Utility model content
In order to solve the problems of the prior art, the purpose of this utility model is to provide receipts formula fixture in one kind so that should
Fixture conveniently reliably can be clamped or loosened to processing part, and make bite ensure to add away from machined surface
Dimensional accuracy during work.
To achieve the above object, the utility model uses following technical scheme：Receipts formula fixture in one kind, including cylinder
Chuck, be provided with through hole one among chuck, one end of chuck is fixedly connected with chuck fixed cover, and chuck fixed cover is provided with through hole
Two, in addition to the chuck supporting with chuck fixed cover, chuck is provided with screwed hole, in addition to one end is provided with screwed hole, in addition one
End sets threaded connecting rod, and chuck is connected by screw screwed hole and sequentially passes through through hole two, through hole one is connected to connecting rod,
One end of chuck connecting clip fixed cover is fixedly connected with the fixed plate of cylinder, and fixed plate is provided with through hole three in the axial direction, presss from both sides
Head fixed cover both passes through through hole three with chuck.
Using above structure, chuck is fixedly connected with chuck fixed cover, because fixed plate is provided with through hole three, chuck fixed cover
Through through hole three, the fixed plate for being used in fixed workpiece is also fixedly attached to chuck, and chuck is connected by screw screwed hole simultaneously
Sequentially pass through through hole two, through hole one is connected to connecting rod so that chuck is connected by screw with connecting rod, so as to which connecting rod drives
Chuck moves in chuck fixed cover, and to realize clamping of the chuck to workpiece with loosening, the process conveniently realizes
Clamping to workpiece, simultaneously because without three-jaw is adjusted manually, also ensure that the precision in process with loosening.
Chuck fixed cover is cylinder and is provided with open slot, and chuck fixed cover section is U-shaped, the chuck section of supporting setting
To be U-shaped, in the open slot of chuck insertion chuck fixed cover, and moved back and forth in open slot.The open slot of setting is to press from both sides
The insertion of head, it is U-shaped for section, it is pump cover to be primarily due to workpiece, in order to clamp the handling position of pump cover upper end, due to
Bite makes machined surface be not easy to be deformed, while workpiece is not easy loosening and causes lathe accident away from machined surface.
The open slot edge of chuck fixed cover is wedge shape, and the open slot edge contact position of chuck and chuck fixed cover is also supporting
For wedge shape.Disengaging of the setting in order to facilitate chuck in chuck fixed cover, it is easier to clamp and loosen workpiece.
Screwed hole on the screwed hole and chuck of connecting rod one end is in the same size, connecting rod by other end of screw thread with
Digit Control Machine Tool connects.Ensure that chuck can be attached with connecting rod using same root screw, so that it is guaranteed that connecting rod can drive folder
Head motion, wherein connecting rod connection Digit Control Machine Tool, using clamping of the oil pressure realization of Digit Control Machine Tool to workpiece with loosening.
One end setting of chuck connecting clip fixed cover is fluted, and fixed plate is positioned in groove and is fixedly connected with chuck.
Because the diameter of groove and the diameter of fixed plate are consistent, it is ensured that be positioned over fixed plate in groove in a circumferential direction not
It can move, make fixed plate more accurate with chuck in orientation.
Through hole one, the diameter of through hole two are more than the diameter of connecting rod.It ensure that connecting rod can be by through hole one, through hole
Two, so as to drive collet movement.
Chuck inwall opening has protrusion.
In the open slot of chuck insertion chuck fixed cover, there is gap between chuck and chuck fixed cover.It ensure that chuck can
To be moved in chuck fixed cover.
In summary, receipts formula fixture in one kind, the connecting rod by connecting Digit Control Machine Tool are driven in embedded chuck fixed cover
Collet movement, realize to the Quick-clamped of workpiece with loosening, simultaneously because bite is away from the machined surface of workpiece, from
And making machined surface be not easy to be deformed, workpiece is not easy loosening and causes lathe accident in processing, and machining accuracy and can ensures.
