Description
Technical field
The utility model is related to Clamping Device of Injection Moulding Machine component, more particularly to a kind of crank connecting rod clamp for machining.
Background technology
Crank connecting rod is an important composition part in Clamping Device of Injection Moulding Machine, and its integral cast is molded, and two ends are provided with
Two hinged sets, two end faces of hinged set axial direction have certain planarity requirements, it is necessary to carry out Milling Process.
When traditionally, to the end face processing of crank connecting rod hinged set, single toggle can be fixed on milling machine, Ran Houzai
Carry out Milling Process.Now in order to improve the processing efficiency to crank connecting rod, numerous toggles are installed on large-scale milling machine together enterprising
Row processing.As shown in Figure 1, some crank connecting rods 100 are fixed with side by side on the workpiece mounting platform 1 of large-scale milling machine, it is fixed
Mode is as follows：Baffle plate 3 is first fixed with one end of workpiece mounting platform 1, with two crank connecting rods 100 for one group, wherein first
The side of individual crank connecting rod 100 props up the side of baffle plate 3, makes the length direction of crank connecting rod 100 and the length of workpiece mounting platform 1
Direction keeps vertical, and then again by second crank connecting rod 100 close to first crank connecting rod 100, workpiece mounting platform 1 is upper
Locking post 4 is fixed between first crank connecting rod 100 and second crank connecting rod 100, the upper end of locking post 4, which is provided with, to be used to
Compress the pressing plate 6 of two upper surfaces of crank connecting rod 100；When installing second group of crank connecting rod 100, just with previous suite elbow connecting rod
100 side is as resistance surface, by the side of one of crank connecting rod 100 and its laminating, it is ensured that first in second group
The position balance of crank connecting rod 100, installs numerous groups, during processing, the milling cutter of large-scale milling machine is disposable to institute a group by a group like this
The end face for having the hinged set of crank connecting rod 100 is processed, and greatly improves processing efficiency.
But, on the excircle that locking post 4 is against due to the side of second crank connecting rod 100 in every group, in every group
The depth of parallelism of second crank connecting rod 100 and the side of the first crank connecting rod 100 be difficult adjustment, and be difficult ensure, so under the influence of one
The position degree of group crank connecting rod 100, can substantially reduce machining accuracy of the large-scale milling machine to crank connecting rod 100.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of crank connecting rod clamp for machining.
Above-mentioned technical purpose of the present utility model technical scheme is that：A kind of crank connecting rod processing
Fixture, including workpiece mounting platform, are provided with T-shaped chute, one end of T-shaped chute is fixed with along the direction of feed of workpiece mounting platform
It is connected with the locking post that can be slid along T-shaped chute, locking post and is arranged between two crank connecting rods in baffle plate, T-shaped chute

By above-mentioned technical proposal, baffle plate is as an initial benchmark, it is necessary to artificial when it is fixed in T-shaped chute
The perpendicularity gone between regulating fender and workpiece mounting platform；Herein, in fixed dam, perpendicularity is difficult to ensure, therefore,
Can occur after baffle plate fixes, its perpendicularity situation devious, but retighten baffle plate and comparatively bother；Therefore, can be with
By rotating adjusting screw, adjusted by the adjusting screw of baffle plate both sides between first crank connecting rod and workpiece mounting platform
Perpendicularity, it is easy to operate.
It is preferred that, one end that adjusting screw rod contradicts crank connecting rod is rotatably connected to abutting set, and baffle plate presses close to crank connecting rod
The counterbore worn for abutting set is simultaneously provided with, guiding rib is axially arranged with along counterbore, pushes against and puts provided with being oriented to rib cooperation
Guide groove.
By above-mentioned technical proposal, push against and cover in extended or retraction counterbore, but push against to be enclosed on and be oriented to rib and guide groove
It will not produce and circumferentially rotate under coordinating, the side of crank connecting rod is pushed against by pushing against set, adjusting screw rod end on the one hand can be reduced
Damage of the portion to crank connecting rod side；On the other hand promotion of the adjusting screw rod to crank connecting rod can be made more steady.
It is preferred that, the lower end of pressing plate is provided with rubber blanket.
Pass through above-mentioned technical proposal, the setting of rubber blanket, it is possible to reduce damage of the pressing plate to crank connecting rod upper surface；Together
When, can make that pressing plate and crank connecting rod upper surface press is even closer.
It is preferred that, the upper surface of locking cap is deviateed at locking cap axle center provided with the rotating bar for being easy to rotation lock cap.
, can be without can easily realize locking cap by extra instrument by rotating bar by above-mentioned technical proposal
Rotate, it is easy to operate.
It is preferred that, the top of rotating bar is hinged with extension rod that can be downward or upward.
By above-mentioned technical proposal, because the space between workpiece mounting platform and large-scale milling machine top is limited, therefore turn
Lever is difficult long, and still, rotating bar is short, then does not change hands by operation；Therefore, it is hinged what can be rotated upwardly and downwardly on the top of rotating bar
Extension rod, when needing rotation lock cap, can be rotated up extension rod, hand grabs extension rod and turning set is rotated；When not
When needing rotation lock cap, extension rod is bent downwards, you can avoid extension rod and lathe from interfering.
