It is that each automotive expert has to consider the problems of.A kind of transmission output shaft need to process three oilholes and one group blind
Hole, as shown in Figure 1.Traditional axis class Drilling operation technique is that substep carries out.Oilhole on subdrilling shaft, then drill out zero
Part Blind locating holes.Blind locating holes also need manual clamping completion twice because there is symmetry requirement.Entire Drilling operation work efficiency is low,
And multiple clamping, machining accuracy are bad；Manual clamping labor intensity is big.
The content of the invention
The purpose of this utility model is to provide a kind of axis class double-station boring grabs, overcome primitive axis class Drilling operation multiple
The shortcomings that clamping machining accuracy is high, manual clamping labor intensity is big.
A kind of axis class double-station boring grab, it is characterised in that：Including bottom plate, V-block, bearing, compression spring assembly, turn
Angle oil cylinder, pressing plate, shop bolt component, V-block are mounted on by soket head cap screw on bottom plate, play radial positioning；Compression
Spring assembly includes mandril, thread bush, compression spring, plug, and installation in the holder, plays axial pretightening；Bearing passes through interior
Hex screw and straight pin are fixed on bottom plate；Pressing plate is connected by bolts to be fitted together with corner oil cylinder, and workpiece is carried out
It compresses and unclamps, corner oil cylinder is bolted on bottom plate；Shop bolt component includes minor thread set, shop bolt, bullet
Spring, small plug in the V-block of lower-left, when second station is processed, position blind hole, Baoding blind hole it is symmetrical
Degree；Vent line is processed in bottom plate, with corner oil cylinder and machine tool hydraulic system unicom, forms hydraulic circuit.
A kind of axis class double-station boring grab, it is characterised in that：To ensure that fixture is durable, the position portion of V-block is all pacified
It equipped with cushion block, is mounted on screw on V-block, when also ensureing that fixture makes, convenient for calibrating the centre-height of two stations, workpiece pressure
It is tight steady.
The utility model has the advantages that：The work that the utility model will originally need two procedures to complete, is merged into together
It is processed in process, improves work efficiency；It in second station, is positioned using shop bolt, ensures the symmetry requirement of blind hole；Profit
With the hydraulic system and steering cylinder of lathe, clamping by hand is become into hydraulic clamp, alleviates the intensity of labourer, work is high
Effect, registration, rapid operation.Axially position is close to V-block end face by the pretightning force for compressing spring, parts to be processed, protects
Demonstrate,prove axial dimension precision；Shop bolt is close to blind hole, ensures the symmetry requirement in hole, and pass through by the pretightning force of spring
Change the outer diameter and length positioning of shop bolt, different size, the axis class blind hole boring requirement of different depth can be applicable in.

Specific embodiment
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
A kind of axis class double-station boring grab, it is characterised in that：Including bottom plate 1, V-block, bearing, compression spring assembly,
Corner oil cylinder 20, pressing plate, shop bolt component, V-block are mounted on by soket head cap screw 5 on bottom plate 1, are played radial positioning and are made
With；Compression spring assembly includes mandril 14, thread bush 15, compression spring 16, plug 17, and installation in the holder, plays axial pretightening
Effect；Bearing is fixed on by soket head cap screw 5 and straight pin 6 on bottom plate 1；Pressing plate is connected by bolts 7 and corner oil cylinder 20
It fits together, workpiece is compressed and is unclamped, corner oil cylinder 20 is fixed on by bolt 26 on bottom plate 1；Shop bolt group
Part includes minor thread set 22, shop bolt 23, spring 24, small plug 25, in lower-left V-block 3, adds in second station
Man-hour positions blind hole, the symmetry of Baoding blind hole；The processing vent line in bottom plate 1, with corner oil cylinder 20 and lathe liquid
System communication is pressed, forms hydraulic circuit.Compression spring assembly is threaded in undersetting 2 and upper bracket 21, root
