Description
Technical field
The invention belongs to Machining of Connecting Rod apparatus field, particularly relate to a kind of crank pin end pore fixture for fine boring.
Background technology
Conventional linkage big end hole fixture for fine boring adopts on base plate, arranges the locate mode of alignment pin and block, and clamp system adopts bolted, and often processing a connecting rod will dismounting fixture, and working (machining) efficiency is low, and labour intensity is large, reduces production efficiency.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of convenient mounting and clamping, crank pin end pore fixture for fine boring that working (machining) efficiency is high.
In order to solve the problems of the technologies described above, the technical solution adopted in the present invention is: a kind of crank pin end pore fixture for fine boring, comprise base plate, described base plate is provided with riser, described riser side is provided with clamp base, and described clamp base is provided with the block of positioning linkage rod and the alignment pin suitable with connecting rod small end hole; Described clamp base is also provided with clamp system, and described clamp system comprises pressing plate, and described pressing plate near middle is provided with pillar installing hole, and described clamp base is provided with pillar, described pillar installing hole and pillar suitable, and pressing plate is swung around pillar; Described pressing plate one end is for compressing end, and the other end is provided with the jacking mechanism holding out against this end.
Described jacking mechanism comprises screw mandrel, and described screw mandrel through riser and clamp base, and is threaded with riser, and one end of screw mandrel contacts with one end of pressing plate, and the other end is provided with handwheel.
Described pillar is set with spring, and described spring one end contacts with clamp base, and the other end contacts with pressing plate.
Described riser and clamp base are provided with the through hole corresponding with crank pin end pore.
Pillar installing hole quantity on described pressing plate is no less than two.
Described pillar installing hole is oval, and the aperture of pillar installing hole is greater than the diameter of pillar.
Described riser is connected with clamp base bolt.
The invention has the advantages that, clamp mechanism utilizes the principle of seesaw, by holding out against pressing plate one end, and make the pressing plate other end compress connecting rod, realize clamping, each clamping only needs rotary screw, and not needing whole remover-and-replacer, clamping efficiency is high, greatly provides production efficiency.
Accompanying drawing explanation

Mark in above-mentioned figure is: 1, base plate, and 2, riser, 3, clamp base, 4, pressing plate, 5, pillar, 6, block, 7, alignment pin, 8, screw mandrel, 9, handwheel.
Detailed description of the invention
Fig. 1 and Fig. 2 is the structural representation of a kind of crank pin end pore fixture for fine boring of the present invention, comprise base plate 1, base plate 1 is provided with riser 2, and riser 2 side is provided with clamp base 3, and clamp base 3 is provided with the block 6 of positioning linkage rod and the alignment pin 7 suitable with connecting rod small end hole; Clamp base 3 is also provided with clamp system, and clamp system comprises pressing plate 4, and pressing plate 4 near middle is provided with pillar installing hole, and clamp base 3 is provided with pillar 5, pillar installing hole and pillar 5 suitable, and pressing plate 4 can be swung around pillar 5; Pressing plate 4 one end is for compressing end, and the other end is provided with the jacking mechanism holding out against this end.
Jacking mechanism comprises screw mandrel 8, and screw mandrel 8 through riser 2 and clamp base 3, and is threaded with riser 2, and one end of screw mandrel 8 contacts with one end of pressing plate 4, and the other end is provided with handwheel 9.Pillar 5 is set with spring, and spring one end contacts with clamp base 3, and the other end contacts with pressing plate 4, and because pillar 5 and pillar installing hole are matched in clearance, spring can hold out against pressing plate 4, makes that pressing plate 4 is unlikely to be rocked on pillar 5.Riser 2 is provided with the through hole corresponding with crank pin end pore with clamp base 3, and boring cutter by this through hole, and can play chip removal effect.
Pillar installing hole on pressing plate 4 can arrange multiple, and to be suitable for the connecting rod of different size, versatility is high.
Pillar installing hole is oval, and the aperture of pillar installing hole is greater than the diameter of pillar 5, thus pressing plate 4 can be swung around pillar 5.Riser 2 is connected with clamp base 3 bolt.
After adopting such structure, clamp mechanism utilizes the principle of seesaw, by holding out against pressing plate 4 one end, and make pressing plate 4 other end compress connecting rod, realize clamping, each clamping only needs rotary screw 8, and not needing whole remover-and-replacer, clamping efficiency is high, greatly provides production efficiency.
Above by reference to the accompanying drawings to invention has been exemplary description; obvious specific implementation of the present invention is not subject to the restrictions described above; as long as have employed the improvement of the various unsubstantialities that method of the present invention is conceived and technical scheme is carried out; or design of the present invention and technical scheme directly applied to other occasion, all within protection scope of the present invention without to improve.
