Description
Technical field
The utility model relates to bearing extractor technical field, specially a kind of needle bearing front output shaft dismantles work
Tool.
Background technique
Bearing is one of components important in contemporary mechanical equipment, is mainly used for supporting mechanical rotary body, reduces machine
Coefficient of friction in tool rotary body motion process, and guarantee the convolution precision of mechanical rotary body in mechanical equipment, in order to ensure
Bearing can work normally, and need that periodically bearing is safeguarded and replaced, therefore inevitably need to dismantle bearing, mesh
Before, bearing is usually used La Mashi specific purpose tool and is dismantled, bearing is caught on by the drag hook on La Mashi specific purpose tool, and
Rotating handle, to drive pull rod to rise, so that bearing be extracted from workpiece, still, when the bearing for needing to dismantle outer ring with
When workpiece contacts, due to very close to each other between the outer ring and workpiece of bearing, cause drag hook that can not catch on bearing, so as to cause bearing
It is difficult to dismantle.
Existing needle bearing front output shaft extracting tool needs handle to carry out rotation loosening to it during use,
So that the tool is had limitation in use, while directly carrying out work on the tool with nut and being prone to wear the work
Tool shortens the tool life, and when dismantling bearing, since bearing is in different size, it is not easy to fixed.
Utility model content
The purpose of this utility model is to provide a kind of needle bearing front output shaft extracting tools, to solve above-mentioned background skill
The existing needle bearing front output shaft extracting tool proposed in art needs handle to carry out rotation pine to it during use
It is dynamic, so that the tool is had limitation in use, while directly carrying out work on the tool with nut and being prone to wear this
Tool shortens the tool life, and when dismantling bearing, since bearing is in different size, it is not easy to fixed problem.
To achieve the above object, the utility model provides the following technical solutions: a kind of needle bearing front output shaft disassembly work
Tool, including bracket, there are two pulling claw, two pulling claws tops to be welded with expansion-head, the bracket for the rack bore setting
Through screw rod is welded with, the screw tip is threaded with nut, and the nut right side wall is welded with connecting rod, the expansion
Overhead inner cavity is welded with fixed block, and the expansion-head outer surface is provided with screw hole, and the screw hole bottom is provided with screw seam, institute
It states rack bore and is socketed with spring shim, the spring shim central location is threaded with nut, the nut central location
It is threadedly coupled screw rod.
Preferably, the pulling claw is mutually welded with sleeve depending on side, and the sleeve is located at rack bore lower center position.
Preferably, the top of the screw rod welding and expansion-head.
Preferably, the nut is stainless steel nut.
Preferably, the fixed block central location is provided with through-hole, and screw thread is provided in through-hole, the hole size and spiral shell
Bar is in the same size.
Compared with prior art, the utility model has the beneficial effects that by needle bearing front output shaft extracting tool
The connecting rod that is connected to of nut weld, can use other tools and loosened or tightened, not by the limitation of spanner, using more
It is convenient, while the elastomeric pad being socketed by nut bottom can prevent nut from improving the tool to the abrasion of the tool
Service life, then different size of bearing can be fixed by the fixed block in expansion-head, it prevents in use
Bearing's looseness influences the working efficiency for dismantling bearing.
Detailed description of the invention
Fig. 1 is the utility model overall structure diagram；
Fig. 2 is the utility model expansion-head structural schematic diagram；
Fig. 3 is the utility model entirety overlooking structure diagram.
In figure: bracket 1, pulling claw 2, expansion-head 3, nut 4, connecting rod 5, fixed block 6, screw hole 7, screw stitch 8, spring pad
Piece 9, screw rod 10.
Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
The utility model provides the following technical solutions: a kind of needle bearing front output shaft extracting tool, for convenient to rolling
The tool that pearl bearing front output shaft is dismantled please refers to body 1, including bracket 1, and there are two pulling claws 2 for the setting of 1 inner cavity of bracket, lead to
Cross pulling claw 2 bearing to be fixed and disassembly, at the top of two pulling claws 2 be welded with expansion-head 3, be for convenience to bearing into
Row socket, 4 right side wall of nut are welded with connecting rod 5, can use other tools such as steel pipe with through-hole to 4 turns of nut
Dynamic, not by the limitation of spanner, bracket 1 facilitates installation nut, 10 screw top of screw rod is connected with spiral shell through screw rod 10 is welded with
Mother 4 is easy to use and is acted on using power by bearing removal, can be with referring to Fig. 2,3 top inner cavity of expansion-head is welded with fixed block 6
Bearing is fixed, 3 outer surface of expansion-head is provided with screw hole 7, bearing can be fixed by screw, 7 bottom of screw hole
Portion is provided with screw seam 8, is not influenced by screw when conveniently pulling to bearing, referring to Fig. 3,1 inner cavity of bracket is socketed with bullet
