Abstract
Rotary index perforation clamp of the present invention is related to field of machining, more particularly to rotary index perforation clamp, rotary index perforation clamp, including two connected bases, a rotary shaft is provided between two base, one is provided with the middle part of the rotary shaft rotating shaft is connected with by bearing, the central axis of the rotating shaft intersects with the central axis upright of rotary shaft, described rotating shaft one end is provided with a pressing plate, the other end of the rotating shaft is provided with an equi-index plate and driving lever, the driving lever is connected with equi-index plate by equal dividing and positioning pin, once mounting positioning is only needed to be processed to the oilhole of diverse location and angle during workpieces processing of the present invention, electrode does not contact with workpiece when reducing position error and punch work, it not only ensure that machining accuracy, improve work efficiency, it is also greatly reduced percent defective.
Description
Technical field
The present invention relates to field of machining, and in particular to rotary index perforation clamp.
Background technology
A kind of bearing, its inner ring all have higher requirements to the dimensional accuracy and positional precision of oilhole, and vertical oilhole is with tilting
Oilhole is mutually corresponding, and simultaneously vertical oilhole oilhole vertical with another side is circumferentially interlaced, and oilhole size is small, interior loop material
Expect for M50 steel more difficult to process.Processed according to traditional pincers worker drill jig, the design and manufacture difficulty of drill jig is big, and is processing
During oilhole, because material hardness is big, processes careless drill bit and be very easy to fracture in workpiece, percent defective is higher.In addition, tilt oil
By oil duct, the oilhole after processing in heat treatment process is easily blocked, is difficult to clean up in hole, cost increase.
The content of the invention
In order to solve the above problems, the present invention provides one kind only needs once mounting positioning can be to difference in workpieces processing
The oilhole of position and angle is processed, and electrode does not contact with workpiece when reducing position error and punch work, not only
Machining accuracy is ensure that, improves work efficiency, is also greatly reduced the rotary index perforation clamp of percent defective.
Rotary index perforation clamp of the present invention, including two connected bases, a rotary shaft is provided between two base,
One is provided with the middle part of the rotary shaft rotating shaft, the central axis of the rotating shaft and the center of rotary shaft are connected with by bearing
Axis intersects vertically, and described rotating shaft one end is provided with a pressing plate, and the other end of the rotating shaft is provided with an equi-index plate and driving lever, institute
Driving lever is stated with equi-index plate by equal dividing and positioning pin to be connected.
Preferably, an alignment pin is provided between base and rotary shaft.
Preferably, some equidistant apertures are distributed with equi-index plate.
Preferably, rotating shaft is connected by deep groove ball bearing with rotary shaft.
Only need once mounting positioning to be processed to the oilhole of diverse location and angle during workpieces processing of the present invention, subtract
Electrode does not contact with workpiece when having lacked position error and punch work, not only ensure that machining accuracy, improves work efficiency, also
Greatly reduce percent defective.
Brief description of the drawings
Fig. 1 is the structural representation of rotary index perforation clamp.
Reference：1- bases, 2- alignment pins, 3- pressing plates, 4- rotating shafts, 5- workpiece, 6- rotary shafts, 7- equi-index plates, 8- are dialled
Bar, 9- equal dividing and positioning pins.
Embodiment
Rotary index perforation clamp of the present invention, including two connected bases 1, a rotation is provided between two base 1
Axle 6, the middle part of the rotary shaft 6 are provided with one and are connected with a rotating shaft 4, the central axis of the rotating shaft 6 and rotation by bearing
The central axis upright of axle 6 intersects, and described one end of rotating shaft 4 is provided with a pressing plate 3, and the other end of the rotating shaft 3 is provided with first-class
Divide disk 7 and driving lever 8, the driving lever 8 is connected with equi-index plate 7 by equal dividing and positioning pin 9.One is provided between base 1 and rotary shaft 6
Alignment pin 2.Some equidistant apertures are distributed with equi-index plate 7.Rotating shaft 4 is connected by deep groove ball bearing with rotary shaft 6.
When operating fixture, workpiece 5 is compressed in rotating shaft 4 with nut first, passes through rotation of the rotary shaft 6 on base 1
Turn, positioned with alignment pin 2, make the axis of workpiece 5 vertical with electrode；Then selected with driving lever 8 and alignment pin 2 on equi-index plate 7 etc.
Divide hole count, according to the difference of workpiece 5, correspondingly decile oilhole is selected on equi-index plate 7, while drive rotating shaft 4 to rotate, to workpiece
5 carry out the indexing of circumferential apertures；The axial distance of each oilhole is ensured by the accurate movement of lathe digital display grating coordinatometer, through the above
The vertical oilhole on the both sides of workpiece 5 can be processed after adjustment.When processing tilts oilhole, rotary shaft 6 need to only be made once respectively suitable
Hour hands and rotate counterclockwise to adaptation angle, insert alignment pin 2, it is accurate in digital display grating coordinatometer by size is calculated
Under mobile and equal dividing and positioning pin 9 indexing effect, electro-discharge machining can be carried out to tilting oilhole.
