Description
Technical field
The utility model belongs to snow Neil machine technical field, and in particular to a kind of snow Neil machine spindle bearing puller.
Background technique
Ring spinner spindle is a component very crucial in production in snow Neil machine, since its revolving speed exists substantially
5000r/min or so, load-bearing are in 500~1000g, and its revolving speed and load-carrying are born by spindle bearing, so to spindle
The quality requirement of bearing is very high, even if in this way, spindle bearing abrasion loss is also very greatly, to need to frequently replace.
It is tight fit between spindle bearing and bolster (as shown in fig. 6, spindle bearing 100 includes in ring spinner spindle
With the load segment 101 of 200 tight fit of bolster and extend to the extended segment 102 outside bolster 200,102 periphery wall of extended segment and assembly
The first tapered surface 103 is formed between 101 periphery walls of section；200 periphery wall of bolster then has annular convex platform 201), so replacing
Difficulty is very big when spindle bearing.The method of spindle bearing is removed in traditional technology typically first by entire ring spinner spindle
It is disassembled from equipment, clips bolster with bench vice, then the spindle bearing that hits with a hammer can make spindle bearing be detached from ingot
Foot, beating position during percussion is it occur frequently that deviate, so that causing to damage to entire bolster；Also certain enterprises are taking ingot
When sub- bearing, first spindle bearing is welded on some discarded parts with electric welding, then taps discarded parts thus by spindle axis
It holds and is taken out on bolster, bolster is caused to damage to avoid tapping.
Above etc. operating method is multifarious, but workload is very when replacing spindle bearing for the prior art in general
Greatly, it operates also cumbersome, and since bolster is also removed or is damaged, by spindle bearing that is new or having repaired
After being installed on bolster, it is also necessary to be positioned to spindle center.
The workload that disassembly spindle bearing can be greatly reduced using bearing puller, avoids bolster by unnecessary damage
Wound.Such as application No. is the Chinese utility model patents of CN201621126083.X to disclose a kind of bearing puller, the bearing puller
Including mounting plate, through being equipped with for installing screw flight hole on the mounting plate, the top of screw rod is integrally provided with turning
Wheel, one end that screw rod passes through mounting plate are then equipped with plane bearing；It is slidably fitted on the mounting plate in screw rod two sides
Two sliding blocks, sliding block is fixedly installed with pull rod backwards to the side of mounting plate, and is then equipped on pull rod and is fixedly installed with and draws
The pulling plate of the L-shaped setting of bar.
The bearing puller is disadvantageous in that (1) is using dynamics when pull rod and the progress drawing of pulling plate banding spindle bearing
Excessively thin, the pressure that when drawing generates can damage the relationship that is fixedly connected between pull rod and pulling plate, at any time may between the two
It is broken, influences the disassembly of spindle bearing；(2) screw rod is in the center of mounting plate to resist wheel shaft, but resists in ingot
Sub- bearing centre, the lesser shaft of area with drawing be in shaft periphery, the biggish spindle bearing of area be still very
Laborious, although and be mounted with plane bearing in screw rod end to reduce the friction between screw rod and wheel shaft, screw rod is to wheel
The damage of axis is inevitable.
Utility model content
Present invention purpose is to provide a kind of easy to operate, small and exquisite quick and will not cause damage to important component
Avenge Neil machine spindle bearing puller.
For achieving the above object, the technical solution of the application is as follows:
A kind of snow Neil machine spindle bearing puller, including two banding bodies being fixedly connected, two banding bodies are oppositely arranged
And surround the banding hole being adapted with spindle bearing periphery wall；
Offered on banding hole periphery, the banding body with banding hole the first threaded hole disposed in parallel, it is described
Jacking bolt is installed in the first threaded hole, the jacking bolt be used for squeeze bolster periphery annular convex platform so that spindle bearing with
Position lifting occurs for banding body.
The banding body that the application is oppositely arranged first with two surrounds and holds tightly spindle bearing, by into the first threaded hole
It is gradually screwed into jacking bolt, drives banding body reversely to move along jacking bolt the squeezing action of annular convex platform using jacking bolt
It is dynamic, while spindle bearing being driven to be detached from bolster, realize the fast quick-detach of spindle bearing, the operation of whole dismounting process is very easy.
The application is that the annular convex platform having designs above-mentioned snow Neil machine spindle bearing puller using bolster itself, is utilized
Bolt and the annular convex platform mutual extrusion on the outside of spindle bearing are jacked, this, which allows for banding body, more easily to drive

Bolt is to the pressure of annular convex platform and guarantees that pressure is uniform, spindle bearing is promoted to be rapidly separated bolster and will not cause to damage to bolster
Wound.
Surrounding two banding bodies in banding hole, to can be shape identical, is also possible to variform.But as excellent
First, Malaysia and China are born in above-mentioned snow Neil machine spindle axis, the banding body is domed, offers on each banding body recessed
Slot, the groove have the section of semicircular in shape, and the banding hole is enclosed by two grooves.The identical banding of shape
The service performance of body is stronger, and the banding body of arch can reduce the area of banding body, so that banding body is more compact.
Malaysia and China are born in above-mentioned snow Neil machine spindle axis, the banding body includes the banding sheet for being provided with the groove
Body, and it is symmetrically disposed in the linking arm of banding ontology two sides, the linking arm is wholely set with banding ontology；In hoop
Positioning mechanism is equipped between two linking arms of tieholen the same side.A pair of of linking arm of banding hole two sides is consolidated using positioning mechanism
Fixed connection, banding body can hold spindle bearing tightly.
Malaysia and China are born in above-mentioned snow Neil machine spindle axis, first threaded hole is arranged on banding ontology.
Malaysia and China are born in above-mentioned snow Neil machine spindle axis, the positioning mechanism includes being separately positioned on two linking arms
On the second internal thread hole, be equipped with fastening bolt between two the second internal thread holes.
Malaysia and China are born in above-mentioned snow Neil machine spindle axis, the head of the fastening bolt offsets with the linking arm
It leans on, the screw rod of the fastening bolt is pierced by the second internal thread hole and the spiral shell to lean with the linking arm that is screwed
It is female.
Compared with prior art, the utility model has the following beneficial effects:
(1) the banding body that the application is oppositely arranged first with two surrounds and holds tightly spindle bearing, by the first screw thread
It is gradually screwed into jacking bolt in hole, drives banding body anti-along jacking bolt the squeezing action of annular convex platform using jacking bolt
To movement, while spindle bearing being driven to be detached from bolster, realize the fast quick-detach of spindle bearing, the operation of whole dismounting process is very simple
Just.
(2) the application is that the annular convex platform having designs above-mentioned snow Neil machine spindle bearing puller using bolster itself,
Using jacking bolt and the annular convex platform mutual extrusion on the outside of spindle bearing, this allows for banding body can be more easily
