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 utility model is provided with at the end extracting bar 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 utility model 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 utility model compared with prior art, has following advantage and beneficial effect:
1, the utility model overall structure 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 utility model can be substantially increased;
2, the utility model 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;
3, the utility model 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.
