Abstract
The invention relates to a special spanner for pressing in a rear-wheel hub bearing, which belongs to the field of special tools for automobile assembly. The invention aims to mainly solve the technical difficult problem of difficult pressing of a rear-wheel hub bearing unit in the car development process. In the invention, a sleeve is fixedly connected with an interface sleeve, a screw is connected with the sleeve through threads, the tail end is placed inside the interface sleeve, and a workpiece threaded sleeve is arranged at the top end of the screw. The invention effectively ensures that after the wheel hub bearing unit is sleeved on the sleeve, the radial position degree deviation, the verticality deviation of the axial line of the sleeve relative to the pressure action surface of a bearing inner ring and the position degree deviation of the wheel hub bearing unit on the radial direction of the sleeve can not be generated due to the gravity action of the sleeve and the wheel hub bearing unit. Meanwhile, the invention also can fully ensure that the pressure can be uniformly acted on the end surface of the bearing inner ring and the inside diameter and a shaft are not mutually damaged in the pressing-in process.
Description
Technical field
The invention belongs to automobile assembling specific purpose tool field.
Background technology
Owing in the dust blocking tray of A130 type car rear brake and the bottom surface of the hub-bearing unit distance 7mm is arranged.So, must with bolt dust blocking tray and hub spindle be fastened on the rear axle earlier in the assembling process; Again hub-bearing unit is pressed into hub spindle; Assemble other parts.
But be interference fit between hub spindle and bearing unit, and bearing inner race is positioned at wheelboss flange centre bore inside.Usually line production all adopts special purpose machine tool to press-fit.Trial-production exploitation and after-sales service then do not have such condition.The latter often adopts hammering method.But the employing hammering method, because bearing inner race is positioned at wheelboss flange centre bore inside, percussion power can't evenly pass to bearing inner race.Will certainly cause the bearing inner race and the generation of axle to tilt, cause the surface damage of bearing inner race or axle simultaneously, thereby the directly assembly precision and the service life of influence spool and bearing improve percent defective greatly.
Summary of the invention
Purpose of the present invention mainly solves the rear wheel hub bearing that the rear axle hub-bearing unit that runs in the car development process press-fits difficult technical barrier and is pressed into special spanner.
Sleeve of the present invention is fixedlyed connected with the interface sleeve, and screw rod is connected with sleeve by screw thread, and tail end places the interface sleeve inner, in screw tip the workpiece thread bush is arranged.
The present invention has interface on the interface sleeve.
The present invention has rim of a cup in the corresponding screw tip of sleeve.
The present invention is equipped with stop nut on the screw rod tail end.
The present invention with leading screw with nut, screw and sleeve is ingenious combines, utilize worm drive steadily strong characteristics finish the technical process that bearing is pressed into hub spindle.
The present invention has effectively guaranteed after hub-bearing unit is sleeved on the sleeve, the not reason gravity effect and produce radial position degree deviation of sleeve and hub-bearing unit, and the axis of sleeve with respect to the perpendicularity deviation of bearing inner race pressure acting surface and hub-bearing unit in position degree deviation that sleeve directly makes progress.Simultaneously, can also fully guarantee in process of press in pressure can stepless action on the end face of bearing inner race and internal diameter does not damage mutually with axle.
Description of drawings
Fig. 1 is a structure cutaway view of the present invention.
The specific embodiment
Sleeve 4 of the present invention is fixedlyed connected with interface sleeve 6, and screw rod 2 is connected with sleeve 4 by screw thread, and tail end places interface sleeve 6 inside, on screw rod 2 tops workpiece thread bush 1 is arranged.
The present invention has interface 7 on interface sleeve 6.
The present invention has rim of a cup 3 on sleeve 4 corresponding screw rods 2 tops.
The present invention is equipped with stop nut 5 on screw rod 2 tail ends.
The present invention is by leading screw, and sleeve, 1/2 " form by the interface sleeve.Described leading screw front end is processed into cylindrical place, the described sleeve of a nut top and processes symmetrical two planes.Center position processing internal thread in top forms nut sleeve and leading screw is assembled together, and after the leading screw end is with the double nut locking, sleeve top welding 1/2 " interface sleeve.
The length overall 200mm that corresponding A 130 cars of the present invention use; External diameter φ 50mm; Heavy 2kg; Leading screw screws out back total length 250mm fully.Have characteristics for profile is little, in light weight, efficient is high, handling safety is light.
Embodiment:
1, with hand screw out left leading screw to sleeve rim of a cup farthest.
2, the rear wheel hub bearing unit is enclosed within on this spanner.The leading screw front end nut is exposed to outside the bearing unit.
3, with hand the leading screw front end nut is revolved and on the screw thread of rear drum axle.
4, with pneumatic impact spanner or hand-operated tools sleeve is screwed, along with the displacement of sleeve on leading screw, hub-bearing unit Bei Zhun Que ﹑ Jun Yun ﹑ is pressed into hub spindle reposefully.
5, oppositely unscrew sleeve.Along with unscrewing of sleeve, the leading screw front end nut also gets loose from hub spindle thereupon.
6, check: bearing is pressed on the hub spindle reposefully, and bearing surface does not have any damage, and the bearing assembly precision is guaranteed.
