at present, industrial and mining enterprises are large-scale, split type bearing shell with bearing shell, and dimensions is generally between Φ 2100 ~ 2500mm, and the weight of a secondary bearing shell is generally 2 ~ 4 tons of left and right.This bearing shell, before casting tungsten gold, is called a watt body; Watt body, before upper vertical Vehicle Processing, can be processed after need to returning circle to close with connector handle.And existing method is exactly outside and beats with sledgehammer, inner hole is supported with jack, adjusts very heavyly, wastes time and energy, very inconvenient.
Summary of the invention
the utility model is exactly for the problems referred to above, makes up the deficiencies in the prior art, provide a kind of time saving and energy saving, adjust that precision is high, watt body, closing tension device, has solved current watt of body the problem of closing centering difficulty very easily.
for realizing above-mentioned purpose of the present utility model, the utility model adopts following technical scheme.
the utility model is by adjusting sleeve, adjusting lever, leading screw, and left gripping mechanism and right gripping mechanism formation, its structural feature is: left gripping mechanism and right gripping mechanism are separately fixed on the adjusting lever of adjusting sleeve both sides, and with respect to the setting that is centrosymmetric of the center of adjusting sleeve; Adjusting sleeve is a cylindrical tubular body, at the two ends of adjusting sleeve, is fixedly installed respectively plug, and the rotation direction of two plugs is contrary; Described leading screw has two, and one end is corresponding with two plugs respectively, and the other end of two leading screws is fixedly linked with the adjusting lever at left gripping mechanism and right gripping mechanism place respectively; Left gripping mechanism and right gripping mechanism are all to consist of interior claw and outer claw, and interior claw is relative with outer claw and be vertically arranged on adjusting lever, and the side of interior claw and outer claw is provided with joint hole, has bolt in joint hole; In described adjusting sleeve, be also provided with handle.
described plug is trapezoidal thread plug, and described leading screw is trapezoidal threaded lead screw.
the beneficial effects of the utility model compared with prior art.
of the present utility model watt of body is the special device of adjusting watt body mutual alignment closing tension device, is applicable to adjust the large axle bush that central angle is 120 degree.It is a kind of mechanical driving device, by leading screw, screw, carry out transmission, leading screw, screw adopt trapezium structure, utilize the advantages such as its driving torque is large, self-locking property is good, realizing watt body shrinks and expands, according to physical dimension, adjust arbitrarily, but also can realize fine setting, make watt body more accurate closing.
facts have proved, by adopting device of the present utility model, alleviated workman's labour intensity, improved operating efficiency; Originally secondary watt of body of unification needed to 3 hours, only needs 1 hour now, time shorten twice; Adjustment precision improves, and originally alignment error is 1.0 ~ 1.5mm, uses tension device adjustment, and error is 0.3 ~ 0.5mm, and the handle that has improved watt body closes precision, has played important function for improving the quality of products.
Accompanying drawing explanation
