Description
Technical field
The present invention relates to LL type oil sealing, specifically refer to that one pulls out cover machine.
Background technology
LL type oil sealing is used for the sealing of 353130B compact bearings, can reach the minor axis of 353130B compact bearings not flexible, increase the object in service life, the use of LL type oil sealing simultaneously reduces the friction torque of bearing integral, not only avoid micro-abrasive particle that shakes and invade bearing, also make bearing have good sealing property, improve grease service life within the bearing.
But in the long-play process of locomotive, for ensureing the stable operation of locomotive, need regularly in time to carry out detections replacing to LL type oil sealing, normally the oil sealing of temporarily sealing is moved back in the Renewal process of LL type oil sealing and unload groove and open, then utilize the instruments such as pliers that oil sealing is pulled out bearing, because press-fiting of LL type oil sealing is realized by hydraulic pressure press mounting die, therefore oil sealing is close on bearing, need during manual operation to expend the larger amount of labour, add the live load of workman, and inefficiency; Another kind of settling mode extracts equipment by large-scale exact automatic, but this kind of mode cost is higher, and ordinary enterprise is difficult to accept.
Summary of the invention
The object of the present invention is to provide one to pull out cover machine, facilitate extracting fast of LL type oil sealing, and then reach and reduce workload, improve and extract the object of efficiency.
Object of the present invention is achieved through the following technical solutions:
One pulls out cover machine, comprise the base for supporting that bottom offers U-lag, the through hole and hole of giving up the throne that are interconnected is had in described base for supporting upper end, extract bar to run through through hole and be placed in U-lag, and be arranged with hollow at the middle part of extracting bar and connecting cylinder in the form of a ring, connecting cylinder contacts with through-hole wall, the described outer wall extracting bar is also provided with external screw thread, and the inwall epimere threaded engagement of described external screw thread and connecting cylinder, the described end extracting bar rotates and is provided with clamping dish, the excircle of described clamping dish is symmetrically arranged with two arc-shaped recess along its center of circle, and the external diameter of described clamping dish is greater than the external diameter extracting bar, also comprise screw, described screw and connecting cylinder threaded engagement, described in the give up the throne aperture in hole be greater than the external diameter of connecting cylinder, after oil sealing is extracted completely, connecting cylinder is configured to the position in hole of giving up the throne, and connecting cylinder slides until connecting cylinder shifts out U-lag completely along the inwall in hole of giving up the throne.For extracting the low and problem that workload is large of oil sealing efficiency in prior art manually, the present invention designs one and can simplify manually-operated instrument to improve and extract efficiency, during work, manually moving back of temporarily sealing on oil sealing sidewall is unloaded reamer and opened, then the U-lag of base for supporting is placed on the end face of bearing, according to moving back the distance of unloading groove and U-lag bottom land, move extracting bar in the connecting cylinder of hollow, make to be positioned at the clamping dish of extracting bar end and unload groove directly and oil sealing contact internal walls through moving back, then will extract bar by the threaded engagement between external screw thread and connecting cylinder inwall is fixed in connecting cylinder, then spanner is used or other pneumatic equipments start to rotate the screw on connecting cylinder by artificial, connecting cylinder is moved up after threaded engagement with it in through hole, until oil sealing is pulled out completely, overall structure of the present invention is small and exquisite, and the dismounting that can realize between each parts connects, convenient artificial use, and for the bearing that all kinds of model is different, the position of extracting bar is adjustable, even if the oil sealing sidewall of each bearing is different from the spacing between U-lag bottom land, extracts bar and still accurately through moving back the contact internal walls unloading groove and oil sealing, applicability of the present invention can be substantially increased, the hole of giving up the throne be connected with through hole meets, and the aperture in hole of giving up the throne is greater than the external diameter of connecting cylinder, after oil sealing is extracted completely, connecting cylinder slides along the inwall in hole of giving up the throne, until connecting cylinder shifts out U-lag completely, to complete base for supporting with connecting cylinder and extract being separated of bar, conveniently store, and clamping dish with extract bar and be rotationally connected, namely clamping dish is not with connecting cylinder and extract bar and rotate, and then the friction reduced between clamping dish outer surface and oil sealing inwall, reduce power consumption when rotating screw, on the excircle of clamping dish, be symmetrically arranged with two arc-shaped recess with its center of circle simultaneously, while guarantee clamping dish supports oil sealing inwall good contact, effectively prevent oil sealing from coming off in withdrawal process, improve the operating efficiency that oil sealing pulls out cover.
Further, be fixed with in the bottom of described clamping dish and compel into cone.Before oil sealing is extracted, normally manually use sharp instrument that moving back of temporarily sealing is unloaded groove and broken, and then through move back unload that groove carries out oil sealing extract operation, the present invention is provided with at the end extracting bar and compels into cone, to extract between bar and oil sealing sidewall while spacing in adjustment, compel directly will move back into cone to unload groove and break, eliminate manually must first break to move back and unload groove the step that puller pulls out to carry out oil sealing is installed again, shorten the working time that oil sealing is pulled out, indirectly improve operating efficiency.
Further, clamping platform is had at the notch place, two ends of described U-lag.Extract bar on move past in journey, base for supporting there will be certain displacement due to stressed, easily make the contact between clamping dish with oil sealing inwall be connected to come off, and then cause oil sealing to extract operation repeatedly carrying out, the present invention offers clamping platform at the notch place, two ends of U-lag, during installation, one side of clamping platform directly contacts with bearing outer rim, the another side of clamping platform respectively with bearing inner wall, wall contacts, base for supporting body is made to be held on bearing, ensure the stability of extracting when bar moves, and then efficiency is extracted in raising.
The present invention compared with prior art, has following advantage and beneficial effect:
1, overall structure of the present invention is small and exquisite, and the dismounting that can realize between each parts connects, convenient artificial use, and for the bearing that all kinds of model is different, the position of extracting bar is adjustable, even if the oil sealing sidewall of each bearing is different from the spacing between U-lag bottom land, extracts bar and still accurately through moving back the contact internal walls unloading groove and oil sealing, applicability of the present invention can be substantially increased;
2, the present invention is provided with at the end extracting bar and compels into cone, to extract between bar and oil sealing sidewall while spacing in adjustment, compel directly will move back into cone to unload groove and break, eliminate manually must first break to move back and unload groove the step that puller pulls out to carry out oil sealing is installed again, shorten the working time that oil sealing is pulled out, indirectly improve operating efficiency;
