Description
Technical field
The invention belongs to crankshaft production machine apparatus field, be specifically related to a kind of vuilt-up crankshaft right boring eccentric orfice flexible jig.
Background technology
Eccentric element is exactly that the cylindrical of part is parallel with the axis of endoporus with cylindrical or cylindrical and do not coincide, the part of deviation certain distance.Eccentric element is applied widely in plant equipment, and in machine driving, gyration becomes linear reciprocating motion or linear reciprocating motion becomes gyration, typically all utilizes eccentric element to complete.The lubricating pump driven with eccentric work piece such as headstock case, the bent axle in automobile engine, the bent axle etc. of lumbering equipment, but the processing technique of eccentric element compares check, and subject matter is the difficult eccentric throw of getting hold of of comparison, and precision is high, and difficulty reaches corresponding tolerance.
Eccentric crankshaft is typically all to be processed on lathe, and their process principle is essentially identical；Mainly take measures in terms of clamping, i.e. the axis centering of the eccentric part needing processing is coincided to lathe spindle rotation axis.In conventional art, the machining accuracy of bent axle is not high enough, does not adapts to high-accuracy mechanical equipment, furthermore, working (machining) efficiency is low.
In view of this, the present inventor provides a kind of vuilt-up crankshaft right boring eccentric orfice flexible jig, and this case thus produces.
Summary of the invention
It is an object of the invention to provide a kind of vuilt-up crankshaft right boring eccentric orfice flexible jig, to solve in conventional art, the precision of the processing of bent axle is not high enough, does not adapts to high-accuracy mechanical equipment.
For above-mentioned technical problem, the concrete technical scheme of the present invention is as follows: a kind of vuilt-up crankshaft right boring eccentric orfice flexible jig, this vuilt-up crankshaft right boring eccentric orfice flexible jig is fixedly installed on boring machine, including the back centre being installed on boring machine by tail block and before being installed on boring machine by front dead head top, described front top and back centre is positioned on same central shaft, and back centre can be along central shaft left and right displacement；Also including sliding axle, this sliding axle is installed on boring machine by sliding shaft base, and described sliding axle is between front top and back centre and near front top；Also including the left clamping plate that are installed on boring machine and right clamping plate, these left clamping plate and right clamping plate are positioned at sliding axle both sides.
Further, described left clamping plate and right clamping plate are fixedly installed on boring machine by left and right clamping plate seat, and clamping plate are movably connected on clamping plate seat by swinging shaft, and described left clamping plate and right clamping plate are in transmission connection by pull bar.
Further, being respectively provided with friction pad inside described left and right clamping plate, the friction pad on left and right clamping plate is symmetrical set.
Further, described pull bar passes through air cylinder driven, and one end of pull bar is connected to cylinder by air cylinder tie rod joint.
Beneficial effects of the present invention: described front top and back centre is positioned on same central shaft, can accurately fix workpiece, it is ensured that the machining accuracy of workpiece；Described left clamping plate and right clamping plate are in transmission connection by pull bar, and left clamping plate and right clamping plate are connected, and can make left clamping plate and right clamping plate synchronous clamping, prevent the asymmetric clamping of left clamping plate and right clamping plate from causing workpiece machining accuracy to reduce；It is respectively provided with friction pad inside described left and right clamping plate, the frictional force of left and right clamping plate can be improved, prevent workpiece from sliding, cause the machining accuracy adding labor cost；Sliding axle can be accurately positioned the position of eccentric orfice.
Below in conjunction with drawings and the specific embodiments, the present invention is described in further detail.
Accompanying drawing explanation
Fig. 1 is present configuration front view；Fig. 2 is present configuration left view.
Detailed description of the invention
As shown in Figure 1, 2, what the present invention disclosed is a kind of vuilt-up crankshaft right boring eccentric orfice flexible jig, this vuilt-up crankshaft right boring eccentric orfice flexible jig is fixedly installed on boring machine 1, including the back centre 3 being installed on boring machine 1 by tail block 2 and by front dead head 4 be installed on boring machine 1 before top 5, described front top 5 and back centre 3 be positioned on same central shaft, back centre 3 can be along central shaft left and right displacement；Also including sliding axle 6, this sliding axle 6 is installed on boring machine 1 by sliding shaft base 7, and described sliding axle 6 is between front top 5 and back centre 3 and near front top 5；Also including left clamping plate 81 and the right clamping plate 82 being installed on boring machine 1, these left clamping plate 81 and right clamping plate 82 are positioned at sliding axle 6 both sides.
Further, described left clamping plate 81 and right clamping plate 82 are fixedly installed on boring machine 1 by left and right clamping plate seat (91,92), and clamping plate 8 are movably connected on clamping plate seat 9 by swinging shaft 10, and described left clamping plate 81 and right clamping plate 82 are in transmission connection by pull bar 11；Described left and right clamping plate (81,82) inner side is respectively provided with friction pad 12, and the friction pad 12 on left and right clamping plate (81,82) is symmetrical set；Described pull bar 11 is driven by cylinder 13, and one end of pull bar 11 is connected to cylinder by air cylinder tie rod joint 14.
In conjunction with Fig. 1, shown in 2, the operation principle of the present invention: the eccentric nose end of workpiece 15 is peaked at front top 5, then move back centre 3 to be withstood by the other end of workpiece 15, in the eccentric orfice of the most mobile sliding axle 6 to workpiece 15, limiting workpiece 15 and rotate and be directed at by eccentric orfice boring cutter, last pull bar 11 drives the left clamping plate in sliding axle 6 both sides 81 and right clamping plate 82 to clamp workpiece 15, by horizontal and vertical for workpiece 15 fixing dead, sliding axle 6 leaves eccentric orfice, and workpiece 15 can be processed by boring cutter.
Shown in Fig. 1, the present invention feels relieved with workpiece 15 two centre bore, sliding axle 6 positioning floating is taked to clamp, can ensure that the requirement of workpiece 15 main shaft eccentric throw ± 0.01 with eccentric ratio axis hole and the depth of parallelism 100: 0.01 of main shaft, it is contained on double main axle machine tool within the time of 5-8 second, once can process two workpieces 15, there is efficiency high, the function that quality is steady.The ratio lathe of transmission, the efficiency of inner circle mill fine grinding endoporus improves yield 4-5 and accompanies, and dimensional stability reaches 99.8%.Significantly reduce production cost and artificial quantity.
Above-described embodiment and the product form of the graphic and non-limiting present invention and style, suitably change that it is done by any person of an ordinary skill in the technical field or modify, all should be regarded as the patent category without departing from the present invention.
