Oilhole A, the B(at small end of connecting rod end are shown in Fig. 1), lubrication channel mainly is provided for the lubrication of piston pin, guarantees to start
The linkage component of machine operates normally.Now by taking the connecting rod of two oilhole forms as an example, two oilholes are along the big aperture line of centres of connecting rod
Angle at 45 ° is distributed in small end of connecting rod end, and oilhole diameter is 5mm, aperture band chamfering.When processing the two oilholes in the past,
Using the hand-operated clamping fixture of fixed single-piece clamping, hole A drilling processing is carried out after the completion of clamping workpiece, after processing is completed
Workpiece is removed in release, is reloaded into hole B progress drilling processing.In this way, clamping workpiece is twice, small end of connecting rod end oilhole could be completed
A, B processing.Clamping is repeated, increases the labor intensity of operator, repeated clamping increases position error, reduces
Production efficiency, is unfavorable for connecting rod large-scale production.
Utility model content
The main technical problems to be solved in the utility model and purpose are: being existed according to current small end of connecting rod end machining of oil hole
Deficiency, a kind of new air-actuated jaw for small end of connecting rod machining of oil hole is designed, to replace original single-piece clamping to press from both sides manually
Tight fixture fundamentally overcomes the phenomenon that labor intensity of workers is big, workpiece positioning accuracy is poor and production efficiency is relatively low, and reaching has
Effect ground improves production efficiency, ensures workpiece quality, adapts to the demand produced in enormous quantities.
Main technical schemes of the invention: the fixture include comprising bottom plate, vertical plate, positioning seat, positioning plate, screw, strut,
Attachment base, pin, bolt, connecting screw, cylinder, cylinder connector, opening pressing plate, locating core, nut, washer, reinforcing rib, it is specific to tie
Structure is, on bottom plate, by pin and the vertical fixed board of bolt, behind bottom plate and vertical plate, vertical welding reinforcing rib, bottom plate and
Before vertical plate, attachment base is installed by screw；On the top of fixture, locating core is installed to vertical plate by washer and nut
In hole and tighten；At the middle part of fixture, cylinder is fixed on attachment base by screw, cylinder connector screws in cylinder and solid
Fixed, the axle sleeve of cylinder is threadedly coupled with connecting screw, and an opening pressing plate, opening pressing plate front end and positioning are inserted on connecting screw
Core is drawn close；In the lower part of fixture, strut is screwed in into attachment base nut and tight, by two positioning seats, passes through pin and bolt difference
It is fixed on the bottom plate on attachment base both sides, then positioning plate is separately fixed on positioning seat by pin and bolt, at this time opening pressure
Plate rear end and strut movable contact.
The utility model passes through probationary certificate: purpose of design is fully achieved, fixture positioning, reliable clamping overcome original
Carry out multiple clamping bring position error, significantly improve small end of connecting rod machining of oil hole precision, quality is stablized；Multiple connecting rods are primary
The labor intensity of clamping simultaneous processing, operator significantly declines, and improves ten times of production efficiency or more；It ensure that production meter
That draws smoothly completes, and meets the needs of large-scale production.

Specific embodiment
Referring to Fig. 2,3,4, be illustrated to the main technical schemes of the utility model: the utility model includes bottom plate 1, stands
Plate 2, positioning seat (see Figure 13,14) 3, positioning plate 4, screw 5, strut 6(are shown in Fig. 7,8), attachment base 7, pin 8, bolt 9, connection spiral shell
Bar (see Figure 11,12) 10, cylinder 11, cylinder connector 12, opening pressing plate 13, locating core 14, nut 15, washer 16, reinforcing rib 17,
Specific structure is, on bottom plate 1, by pin 8 and the vertical fixed board 2 of bolt 9, and behind bottom plate 1 and vertical plate 2, vertical welding
Before reinforcing rib 17, bottom plate 1 and vertical plate 2, attachment base 7 is installed by screw 5；On the top of fixture, locating core 14 is passed through
Washer 16 and nut 15 are installed in the hole of vertical plate 2 and tighten；At the middle part of fixture, by screw 5 by 11 company of being fixed on of cylinder
On joint chair 7, cylinder connector 12 screws in cylinder 11 and fixes, and the axle sleeve of cylinder is threadedly coupled with connecting screw 10, inserts on connecting screw
There is an opening pressing plate 13, opening pressing plate front end is drawn close with locating core 14；In the lower part of fixture, the screw-in attachment base 7 of strut 6 is used
Nut is simultaneously tight, and two positioning seats 3 are separately fixed on the bottom plate 1 on 7 both sides of attachment base by pin and bolt 9, then by pin and
Positioning plate 4 is separately fixed on positioning seat 3 by bolt, and be open 13 rear end of pressing plate and 6 movable contact of strut at this time.
Referring to Fig. 2,3,4, to guarantee air-actuated jaw requirement, accordance tune should be carried out to the fixture after being installed
Examination, it is desirable that the axle sleeve of cylinder is capable of expansion and contraction, does not allow clamping stagnation；Connecting rod aperture can flexible rotating after being packed into locating core 14；Fixture is vertical
The verticality of plate positioning surface and fixture bottom surface allows in the range of 0.02mm；Aperture locating core 14 and fixture vertical plate positioning surface
Verticality allows in the range of 0.02mm；Fit dimension in fixture is given by requirement is typically designed.
Referring to Fig.1,2,3,4, utility model works principle:, air-actuated jaw is mounted on numerically-controlled machine tool, and carry out
Accordance debugging；, remove opening pressing plate 13, four connecting rod E to be processed are fitted into the locating core 14 of fixture, connecting rod weighing
It is rotated under power effect around mandrel, the face connecting rod C is bonded with positioning plate 4, and (the big aperture line of centres of connecting rod and positioning plate are flat at this time
Row), the corresponding station of hole A is gone to, the insertion opening pressing plate 13 on connecting screw 10 and strut 6；, starting device program refers to
It enables, 11 axle sleeve of cylinder, which is shunk, drives opening 13 clamp linkage of pressing plate, has constrained the freedom degree of connecting rod；, equipment compound drilling
Row device to hole A drilling processing, cutter passes through four apertures on locating core 14 one by one, and (locating core opens the knife there are four diameter for 7mm
Have relief hole), four hole A are completed the process, and program, which issues, unclamps instruction, and 11 axle sleeve of cylinder, which stretches drive opening pressing plate 13 and unclamps, to be connected
Then bar rotates four connecting rod E together clockwise, the face D of connecting rod is bonded with positioning plate, goes to the corresponding station of hole B, together
Reason, according to program instruction, 11 axle sleeve of cylinder, which is shunk, drives opening 13 clamp linkage of pressing plate, has constrained the freedom degree of connecting rod again,
