Abstract
The utility model relates to a device for press mounting by using hydraulic pressure, which comprises a screw, a gland nut, a backing ring, a hollow hydraulic oil cylinder, a small pressing sleeve, a lock nut, a small connecting sleeve, a big pressing sleeve, a locking ring, a big connecting sleeve, a hydraulic hose and a hydraulic pump station. The screw is connected on the small connecting sleeve and is locked by the lock nut. The small connecting sleeve is connected on the big connecting sleeve and is locked by the locking ring. The big pressing sleeve is arranged outside the big connecting sleeve. The small pressing sleeve is arranged outside the small connecting sleeve and is in contact with the big pressing sleeve. The hollow hydraulic oil cylinder is sleeved on the screw and is in contact with the small pressing sleeve. The hydraulic hose is connected between the hollow hydraulic oil cylinder and the hydraulic pump station. The backing ring and the gland nut are arranged on the screw and are pressed on the hollow hydraulic oil cylinder. Due to the adoption of the device, the pressing force can be accurately controlled, the assembly quality is improved, the productivity can be improved, the labor intensity can be reduced, the safety can be improved, the work of prepressing and disassembling by an oil press can be canceled, and the logistics transshipment processes are reduced.
Description
Technical field
The utility model belongs to the bull-dozer field, and the press-loading apparatus when relating to the assembling of a kind of bull-dozer relates in particular to a kind of device that uses hydraulic coupling to press-fit.
Background technology
At present, in the bulldozer in China manufacturing industry, during the final transmission system of assembling bull-dozer, for circular cone cooperates, requirement has the bigger power that is pressed into during assembling between its gear hub and the chain wheel hub.But be subjected to the restriction of bull-dozer semiaxial position, be difficult on assembly line, press-fit.Usually the assembly method that adopts is a preloading method: earlier the part that cooperates is fitted together separately, with taking apart after the hydraulic press precompressed, and then assembles with general tool to assembly line again.This method makes operation complicated, has increased the transhipment link simultaneously, has increased working strength of workers, and production efficiency is low, also has certain potential safety hazard.
The utility model content
The purpose of this utility model be to provide a kind of rational in infrastructure, press-fit the device that performance is good, production efficiency is high use hydraulic coupling press-fits.
The technical solution of the utility model is: a kind of device that uses hydraulic coupling to press-fit comprises screw rod, clamp nut, gasket ring, hollow hydraulic jack, little clamping sleeve, locking nut, little adapter sleeve, big clamping sleeve, retaining ring, big adapter sleeve, hydraulic hose, hydraulic power unit; Screw rod is connected on the little adapter sleeve and with locking nut locking, little adapter sleeve is connected that big connection puts and with retaining ring locking, big clamping sleeve is contained in big adapter sleeve outside, little clamping sleeve be contained in little adapter sleeve outside and and big clamping sleeve contact; Hollow hydraulic jack is enclosed within on the screw rod and with little clamping sleeve and contacts, and hydraulic hose is connected between hollow hydraulic jack and the hydraulic power unit; Gasket ring and clamp nut are contained on the screw rod and are pressed on the hollow hydraulic jack.
Little adapter sleeve and screw rod are provided with interconnective internal and external screw thread, on big adapter sleeve and the little adapter sleeve interconnective internal and external screw thread are arranged, and big connection puts and has the internal thread that externally threaded gear hub is connected.
The beneficial effects of the utility model are: can accurately control thrust, improve assembly quality; Can boost productivity, reduce labour intensity, improve security; Can cancel the precompressed carried out with hydraulic press and the work of dismounting, reduce logistics transhipment flow process.
Description of drawings
Accompanying drawing is a kind of cross-sectional view of using the device that hydraulic coupling press-fits of the utility model.
The specific embodiment
The utility model will be further described below in conjunction with accompanying drawing.As shown in drawings, big adapter sleeve 10 is installed in by being threaded on the gear hub 13, little adapter sleeve 7 and big adapter sleeve 10 interconnect by the screw thread of self, and lock with retaining ring 9; Screw rod 1 and little adapter sleeve 7 interconnect by the screw thread of self, and lock with locking nut 6; Big clamping sleeve 8 is sleeved on the outside of big adapter sleeve 10, little clamping sleeve 5 be sleeved on little adapter sleeve 7 outsides and and big clamping sleeve 8 contact; Hollow hydraulic jack 4 be sleeved on the screw rod 1 and and little clamping sleeve 5 contact; Hydraulic hose 11 is connected between hollow hydraulic jack 4 and the hydraulic power unit 12; Gasket ring 3 and clamp nut 2 are contained on the screw rod 1 and are pressed on the hollow hydraulic jack 4.
During work, big clamping sleeve 8 is pressed on the chain wheel hub 14, adjust the operating pressure of hydraulic power unit 12 by thrust requirements of chain wheel hub 14 assembling, operating hydraulically operated pumping plant 12 stretches out the piston of hollow hydraulic jack 4, piston promptly promote little clamping sleeve 5 and greatly clamping sleeve 8 chain wheel hub 14 is compressed; Press-fit finish after, operating hydraulically operated pumping plant 12 makes the piston-retraction of hollow hydraulic jack 4, press-loading apparatus can be pulled down.
In the utility model, the middle part of little adapter sleeve 7, big adapter sleeve 10, little clamping sleeve 5, big clamping sleeve 8 all is empty, can hold the semiaxis 15 of bull-dozer, the virtual condition when adapting to assembling.The utility model also can be made and be used like this: screw rod 1, locking nut 6, little adapter sleeve 7, retaining ring 9, big adapter sleeve 10 combination systems cause a part; Little clamping sleeve 5, big clamping sleeve 8 combination systems cause a part; Clamp nut 2, gasket ring 3 combination systems cause a part.The press-loading apparatus of making by such scheme falls among the claim of the present utility model equally.
