Description
Technical field
This utility model relates to the extracting tool of a kind of machinery industry, draws particularly to a kind of motor bearings dismounting
Pull out device.
Background technology
Bearing is to play parts that are fixing and that reduce load coefficient of friction in mechanical transmission course, is machinery in the present age
A kind of very important parts in equipment.Be arranged on inner edge or outer rim the most respectively wheel shaft or
On axle sleeve, owing to the assemblage gap of bearing is that tight fit is installed, hidden by housing or various Conjoint packing for wine again
Gear, the dismounting of bearing is in periodic maintenance, carries out during bearing replacing, and in unloading process, particularly mistake
Being full of during the bearing removal coordinated, for not damaging the parts of bearing, the operation easier of its dismounting is big.
The defect of prior art: at present, bearing removal process occurs when bearing sleeve is difficult to take off directly with hammer
The way dismounting that son taps, so easily causes the damage of bearing sleeve, increases the consumption of accessory, increase
Add production cost, reduce work efficiency；Device function singleness is drawn in tearing open that existing dismounting coordinates, and structure does not conforms to
Reason, tears open and draws the gripper of device messy in agitated state, brings inconvenience to dismantlement work, and original one
The workload of individual, also needs two people to cooperate, the most time-consuming, but also easily causes industrial accident.
Utility model content
For solving above technical problem, this utility model provides a kind of motor bearings dismounting drawbench, to solve
Bearing removal difficulty, puller unreasonable structure, it is impossible to the problems such as the bearing removal of adaptation sizes.
The technical solution adopted in the utility model is as follows: a kind of motor bearings dismounting drawbench, it is critical only that:
Including screw rod, described screw flight is socketed with axle sleeve, the outer surface of described axle sleeve just to being provided with two pieces of extension boards,
On two pieces of described extension boards, activity is inserted with the hanging part of two respectively；
Described hanging part include connecting plate, the rear end of described connecting plate be provided with adapt with described extension board insert
Connecing hole, the front end of described connecting plate is bent to form hanging plate towards described screw rod.
When above scheme provides the benefit that bearing removal, hanging part can move to adapt to difference on extension board
The bearing of bore and the bearing of different length can change the hanging part with corresponding length connecting plate, will hang
Fishplate bar tangles the front end of bearing, and screw rod withstands bearing, under the effect of external force, and rotary screw, make axle and axle
Holding generation relatively to slide, axle is relative bearing forward slip under the promotion of screw rod, and axle ejects bearing the most at last,
Complete the dismounting of bearing.
Preferably, two pieces of described extension boards are rectangle, and the length direction of two pieces of described extension boards is all and institute
Stating the axially vertical of screw rod, the width of two pieces of described extension boards is all parallel with described axle sleeve axis, two pieces
The width of described extension board is respectively less than and described axle sleeve axial length.
The effect of the program is can more easily to control extension board carry out rotary shaft bearing sleeve and will mount easily
Part is plugged on extension board；And increase the extension board intensity in axis direction stress.
Preferably, the rear end of described screw rod is provided with swivel joint.
The effect of the program is screw rod can be helped to rotate with external tool to eject bearing.
Preferably, described swivel joint is hexahedro prismatic.
The effect of the program is to form multiple card access surfaces can preferably make external tool rotary screw.
Preferably, the front end of described screw rod is provided with apical grafting part.
The effect of the program is that the screw rod being avoided that bearing puller contacts with the direct of workpiece wheel axle end surface.
Preferably, described apical grafting part includes footstock, this footstock be provided with cylinder top.
The effect of the program is in unloading process, when rotary screw exerts a force to part to be demolished, and top energy
Reduce the contact area between screw rod and bearing to be removed, to avoid the installation site impact on dismounting；For
End face has the wheel shaft of depression, in the top depression that can enter wheel axle end surface, is possible to prevent screw rod promoting wheel shaft
During move radially.
Preferably, described top axial line overlaps with the axial line of described screw rod.
The effect of the program is to can ensure that bearing removal drawbench normally and smoothly works.
Preferably, described swivel joint, screw rod, footstock and top one-body molded.
Beneficial effect: compared with prior art, motor bearings dismounting drawbench, the knot that this utility model provides
Structure is simple, simple to operate easy-to-use；Using hanging part to be mounted by bearing, rotary screw impeller-hub is within the bearing
Forward slip, it is possible to easy to do friction tight bearing is pulled down, and part will not be caused damage,
The hanging part of kink adapts to different bore and the bearing of length；Low cost, decreases disappearing of instrument parts
Consumption, substantially increases the service life of instrument.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model；
Fig. 2 is the structural representation of hanging part 4 in Fig. 1.
Detailed description of the invention
For making those skilled in the art be better understood from the technical solution of the utility model, below in conjunction with the accompanying drawings and
This utility model is elaborated by detailed description of the invention.
As shown in Fig. 12, a kind of motor bearings dismounting drawbench, including screw rod 1, described screw rod 1 thread bush
