Description
Technical field
The utility model belongs to gasoline engine technology field, more particularly to a kind of bolt suitable for different model connecting rod
Hole processing clamp.
Background technology
It is well known that the connecting rod of piston of automobile engine is operated under very complicated working environment, when engine exists
When working under higher speed, the reciprocating motion of piston and the friction of Inner Wall of Combustion Chamber can produce very big heat so that piston is located all the time
Force to work in hot environment in one kind, connecting rod is connected with piston, reciprocating motion of the pistons is promoted, therebetween it has to be ensured that very
Small friction.Therefore, connecting rod is one of critical component for ensureing engine normal operation.
In connecting rod production process, traditional connecting-rod bolts hole processing clamp can only process the connecting-rod bolts of same model
Hole, must re-replace connecting-rod bolts hole processing clamp if replacing model, so not only add cost, but also reduce work
Efficiency, and for connecting-rod bolts hole processing clamp structure it is larger when, the also dangerous hidden danger in hoisting process, easily occur
Security incident, damages the safety of operator, while stone tongs repeatedly, can reduce clamp precision, while influence machine
The precision of bed workbench.In real work can there are two kinds even a variety of connecting rods, when size difference is smaller, it may be considered that pass through
Clamp structure is transformed to adapt to the processing of different model connecting rod.
The content of the invention
Problem to be solved in the utility model is overcome the deficiencies in the prior art part and defect, there is provided a kind of center
Away from the adjustable bolt hole processing clamp suitable for different model connecting rod, avoid replacing the difficulty that integral clamp is brought, improve
Work efficiency.
The technical solution adopted in the utility model includes bottom plate, big end clamp plate, big end positioning pin, big end supporting block and oil
Cylinder, riser and centre-to-centre spacing bolt are fixedly mounted on the bottom plate, locking nut is set with centre-to-centre spacing bolt, add on riser
Work centre-to-centre spacing slideway, locking sliding block is provided with centre-to-centre spacing slideway, the left lower of riser be provided with small end positioning pin and
Small end supporting block, small end positioning pin and small end supporting block are threadedly coupled by clamping screw with locking sliding block, locking sliding block
It can be moved up and down under the drive of small end supporting block in centre-to-centre spacing slideway.
Reinforcing rib is installed on the right side of orthogonal riser and bottom plate.
4 centre-to-centre spacing slideways are machined with the riser, locking sliding block is mounted in each centre-to-centre spacing slideway.
The big end positioning pin is interference fit with big end supporting block.
Integral demounting is needed to replace different connecting rod spiral shells from the processing in the prior art for different centre-to-centre spacing connecting rod bolt holes
The technology of keyhole clamp for machining compares, and the beneficial effects of the utility model are, by the improvement to clamp structure, to be suitable for not
With the processing of model connecting rod difference centre-to-centre spacing connecting rod bolt holes, remodeling for fixture only needs to adjust central distance micro regulating mechanism, you can
Completion is remodeled, and the adjustment of the centre-to-centre spacing is coordinated using sliding block and slideway, is finely adjusted simultaneously by the centre-to-centre spacing bolt on bottom plate
It is fixed with locking nut, centre-to-centre spacing is adjusted with the screwing length of centre-to-centre spacing bolt, the locking that is moved through of positioning pin slides
Block coordinates with centre-to-centre spacing slideway to realize, by the adjustment of centre-to-centre spacing bolt, ensure that the precision for operation of remodeling, improves work
Efficiency.
