Description
Technical field
The present invention relates to a kind of frock clamp, and in particular to a kind of frock clamp of machining.
Background technology
Fixture, also known as fixture, is, for fixing processing object, to be allowed to occupy correct position during a kind of machine-building
And to receive the device of construction or detection.In a broad sense, any operation in technical process, for rapid, convenient, safety
The device of workpiece is installed on ground, all can be described as fixture.Such as weld jig, inspection jig, assembling jig, jig etc..
When the side wall of the part more long to axis such as column types drills, typically the two ends of the part are clamped, so
Its side wall is drilled afterwards.But this mode makes the position being located between the fixture of two ends on part be in vacant state, and
During drilling, cutter can produce larger stress to part from top to bottom, therefore quality to the part is impacted, particularly part
Side wall on.For some applicable situations and its important Rotating Shafts, such as alternator shaft of Three Gorges Dam, automobile engine
Bent axle etc., be required for carrying out side wall flaw detection after machining, it is to avoid there is quality to lack because hanging processing causes feature side-wall
Fall into；And the flaw detection that the general part of applicable situation is then seldom applied, but the mass defect produced to its Side wall drill hole is all the time
In the presence of.
The content of the invention
Present invention aim at a kind of frock clamp of machining is provided, solve traditional more long to axis such as column types
Part side wall drilled fixture when, due on part be located at two ends fixture between position be in vacant state,
Feature side-wall is easily set to produce the problem of mass defect.
The present invention is achieved through the following technical solutions：
A kind of frock clamp of machining, including installing plate, locating piece and stopping means, the locating piece are arranged on
On installing plate, the one end away from installing plate on locating piece is provided with stopper slot, and the stopper slot is groove, and its opening size
More than bottom land size, be provided with through hole on the cell wall of stopper slot, and through hole axis perpendicular to cell wall；
The stopping means includes spacing batten, bolt I and nut, and one end of the spacing batten is from the side of stopper slot
Through hole on cell wall is passed, and the through hole of the other end of spacing batten from the opposite side cell wall of stopper slot is passed, the bolt I
Screw rod end is connected after sequentially passing through installing plate and spacing batten with nut, and bolt I and nut have two, and along stopper slot
Axisymmetrical is arranged on the two ends of spacing batten；
Stopping device is provided with the end face vertical with the axis of stopper slot on the locating piece, the stopping device includes
Location-plate and screw rod, the location-plate set and are connected with the end face, and location-plate is parallel with the end face of stopper slot, the screw rod
One end is located in stopper slot after the location-plate, and screw rod is coordinated by screw thread with location-plate, and screw rod diameter parallel in spacing
The axis of groove.
During using the fixture, first cylindrical parts are put into stopper slot, the axis of the part is put down with the axis of stopper slot
OK, and make the part be located between spacing batten and stopper slot, and simultaneously be located at location-plate between；Then nut is tightened, makes limit
Near one end compressing component of bottom land on the batten of position, and then limit the movement of part；Rotary screw again, make on screw rod each other to
Opposite Clamp blocks, and then limit the movement of part；Then from the top of stopper slot to part Side wall drill hole；So not only
