Abstract
Description
Technical field
The utility model belongs to the Machining of Connecting Rod apparatus field, relates in particular to a kind of crank pin end pore fixture for fine boring.
Background technology
Conventional linkage big end hole fixture for fine boring adopts the locate mode that alignment pin and block are set on base plate, and clamp mechanism adopts bolted, and connecting rod of every processing will fixture of dismounting, and working (machining) efficiency is low, and labour intensity is large, has reduced production efficiency.
The utility model content
Technical problem to be solved in the utility model 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 scheme that the utility model adopts is: a kind of crank pin end pore fixture for fine boring, comprise base plate, described base plate is provided with riser, described riser one side is provided with clamp base, described clamp base be provided with positioning linkage rod block and with the suitable alignment pin of connecting rod small end hole; Also be provided with clamp mechanism on described clamp base, described clamp mechanism comprises pressing plate, and described pressing plate near middle is provided with the pillar installing hole, and described clamp base is provided with pillar, and described pillar installing hole and pillar are suitable, and pressing plate can be swung around pillar; Described pressing plate one end is for compressing end, and the other end is provided with the jacking mechanism that holds out against this end.
Described jacking mechanism comprises screw mandrel, and described screw mandrel passes riser and clamp base, and is threaded with riser, and an end of screw mandrel contacts with an end of pressing plate, and the other end is provided with handwheel.
Be set with spring on described pillar, described spring one end contacts with clamp base, and the other end contacts with pressing plate.
Described riser is provided with the through hole corresponding with crank pin end pore with clamp base.
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 the clamp base bolt.
The utility model has the advantage of, 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, and to realize clamping, each clamping only needs rotary screw, and not needing whole remover-and-replacer, clamping efficiency is high, and production efficiency is provided greatly.
The accompanying drawing explanation
The structural representation that Fig. 1 is a kind of crank pin end pore fixture for fine boring of the utility model;
The structural representation that Fig. 2 is Fig. 1 crank pin end pore fixture for fine boring;
Mark in above-mentioned figure is: 1, base plate, 2, riser, 3, clamp base, 4, pressing plate, 5, pillar, 6, block, 7, alignment pin, 8, screw mandrel, 9, handwheel.
The specific embodiment
The structural representation that Fig. 1 and Fig. 2 are a kind of crank pin end pore fixture for fine boring of the utility model, comprise base plate 1, base plate 1 is provided with riser 2, and riser 2 one sides are provided with clamp base 3, clamp base 3 be provided with positioning linkage rod block 6 and with the suitable alignment pin 7 of connecting rod small end hole; Also be provided with clamp mechanism on clamp base 3, clamp mechanism comprises pressing plate 4, and pressing plate 4 near middles are provided with the pillar installing hole, and clamp base 3 is provided with pillar 5, and pillar installing hole and pillar 5 are suitable, and pressing plate 4 can be swung around pillar 5; Pressing plate 4 one ends are for compressing end, and the other end is provided with the jacking mechanism that holds out against this end.
Jacking mechanism comprises screw mandrel 8, and screw mandrel 8 passes riser 2 and clamp base 3, and is threaded with riser 2, and an end of screw mandrel 8 contacts with an end of pressing plate 4, and the other end is provided with handwheel 9.Be set with spring on pillar 5, spring one end contacts with clamp base 3, and the other end contacts with pressing plate 4, and because pillar 5 is matched in clearance with the pillar installing hole, 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 can pass through this through hole, and can play the chip removal effect.
Pillar installing hole on pressing plate 4 can arrange a plurality of, and to be suitable for the connecting rod of different size, versatility is high.
The pillar installing hole is oval, and the aperture of pillar installing hole is greater than the diameter of pillar 5, thereby pressing plate 4 can be swung around pillar 5.Riser 2 is connected with clamp base 3 bolts.
After adopting such structure, clamp mechanism utilizes the principle of seesaw, by holding out against pressing plate 4 one ends, and make pressing plate 4 other ends compress connecting rod, and to realize clamping, each clamping only needs rotary screw 8, and not needing whole remover-and-replacer, clamping efficiency is high, and production efficiency is provided greatly.
The above is exemplarily described the utility model by reference to the accompanying drawings; obviously the utility model specific implementation is not subject to the restrictions described above; as long as adopted the improvement of the various unsubstantialities that method of the present utility model design and technical scheme carry out; or without improving, design of the present utility model and technical scheme are directly applied to other occasion, all within protection domain of the present utility model.
