Description
Technical field
The utility model relates to a kind of bearing press mounting equipment, particularly a kind of propons hub bearing inner ring pressing machine.
Background technology
The assembly technology of propons hub bearing inner ring has two kinds of methods at present, respectively to adopt heating assembling method and the double end hydraulic pressure of the technique of expanding with heat and contract with cold to press-fit method, below will discuss in detail this two kinds of existing defectives of method and deficiency: one, the heating assembling method is before pressing bearing, must be first bearing heating, make it to expand, and then knock by hand assembling with the bearing pressure cylinder; This kind method needs to heat bearing before assembling, and this need to consume a large amount of electric energy; And need before assembling bearing is packed in the heating cabinet, waste time and energy, be unfavorable for the raising of production efficiency; In the process of running in bearings, knock bearing, bearing is damaged.Two, double end hydraulic pressure press-fits method: although this kind method needn't heat bearing before press-fiting, but because front axle steering knuckle has an inclination angle, the inclination angle of different propons kind knuckles is different, and two pressure cylinders 6 of double end propons hydraulic press (referring to Fig. 2) are on the axis by force direction, therefore just caused being subjected to the inconsistent problem of force direction in the process that press-fits, this will cause bearing press mounting not in place; And this method is inconvenient to locate, and needs the double pressing machine that operates together, and making pressure cylinder aim at universal joint can press-fit; And the floor space of machine is larger, operates also not too convenient and swift.Application publication number is: CN102069373 discloses a kind of hydraulic compressing device, the operation principle of this device is: by fixedly guide pin bushing and compressed oil cylinder in the somewhere, hold-down head is installed on the termination of compressed oil cylinder, clamp jaw is fixed on the Connection Block, gripping sleeve is connected guide pillar and is connected with oil cylinder with holder, axle is put into the positioning sleeve of Connection Block, the bearing that press-fits is placed on the axle head, move downward by cylinder piston rod, the drive gripping sleeve moves downward, and then the cooperation inclined-plane by clamp jaw and gripping sleeve produces the other end of a clamping force clamp shaft, then is pressed into bearing; This apparatus structure is comparatively complicated, be not easy to maintenance, and must be fixed in a certain position to fixed cover and can work, be only applicable to all is the axle of naked body, versatility is not strong, for flanged coiled hair or the complicated and diversified front axle steering knuckle of end construction and inapplicable, can't clamp this type of axis products, be not suitable for the pipelining of propons assembling yet.
Summary of the invention
The technical problems to be solved in the utility model is: provide a kind of and can eliminate little, the easy to operate propons hub bearing inner ring pressing machine of impact, floor space that the knuckle inclination angle produces.
The technical scheme that solves the problems of the technologies described above is: a kind of propons hub bearing inner ring pressing machine, this pressing machine is the single head pressing machine, only comprise a cover oil hydraulic cylinder assembly, bearing head, guide pin bushing and stop nut assembly, described oil hydraulic cylinder assembly comprises oil hydraulic cylinder, is positioned at the piston of oil hydraulic cylinder, described stop nut assembly front end is fixedly connected with the propons hub axle tube, and the rear end is passed the piston inner hole of oil hydraulic cylinder assembly and is stuck on this piston end surface; Described bearing head is installed in the front end of oil hydraulic cylinder assembly, and guide pin bushing is installed on the endoporus bottom and the propons hub axle tube between the stop nut assembly of bearing head.
Further technical scheme of the present utility model is: described piston is made of the piston head that is positioned at the middle part and the piston rod integral body that lays respectively at the piston head rear and front end, and wherein the piston rod of front end stretches in the bearing head and between the outer round surface of the inner hole wall of bearing head and guide pin bushing.
Of the present utility model more further technical scheme be: described stop nut assembly comprises all with holding greatly and the attaching nut of small end, stop nut and intermediate casing that attaching nut and stop nut are linked together, attaching nut's large end endoporus and propons hub axle tube are threaded connection, and attaching nut's small end stretches in the intermediate casing and with intermediate casing and is threaded connection; The small end endoporus of stop nut and the other end of intermediate casing are threaded connection, and the large end of stop nut is stuck on the piston end surface of oil hydraulic cylinder assembly.
Owing to adopting said structure, bridge hub bearing inner ring pressing machine compared with prior art has following beneficial effect before the utility model:
1. can eliminate the impact that the knuckle inclination angle produces:
Because the equipment that the utility model adopts is the single head pressing machine, only include a cover oil hydraulic cylinder assembly, bearing head, guide pin bushing and stop nut assembly, the pressing method that adopts is that single head press-fits method, adopt this pressing machine respectively the hub bearing inner ring at propons two ends to be press-fited respectively when namely being pressing bearing, therefore, the impact that the knuckle inclination angle produced when the utility model can avoid double end to press-fit can accurately put bearing press mounting in place.
Simple in structure, floor space is little, easy to operate:
Because the pressing machine that the utility model adopts is the single head pressing machine, need not middle coupling and the hanger bracket of double end propons hydraulic press, and is not only simple in structure, and small volume, floor space is also less; In addition, the single single-set operation of this pressing machine, very convenient quick.
In addition, owing to only needing during the utility model work bearing head is fixed on the oil hydraulic cylinder end face, again the end of thread of stop nut assembly with the propons hub axle tube is connected, the oil hydraulic cylinder of oil hydraulic cylinder assembly and piston produce bidirectional-movement during work, but the limited nut assembly of piston withstands and restraint, oil hydraulic cylinder then drives bearing head bearing inner race is pressed on the hub bearing position, therefore the utility model need not its any parts are fixed in the somewhere, can slinging, it is aerial to place, do not take up room, operate more simple and efficiently, more be applicable to the continuous productive process of assembling, structure is more simple compact, the maintenance of being more convenient for.
3. highly versatile:
The utility model is for the not threaded axle in termination, only need to install additional a location hold-down support, oil hydraulic cylinder is fixed, axle is placed on the bearing, aim at oil hydraulic cylinder axle center horizontal positioned, change corresponding bearing head and get final product pressing bearing, therefore, the utility model is applicable to different axis products, and versatility is stronger.
4. because the utility model adopts is the hydraulic pressure pressing method, do not need to heat bearing, can reduce energy consumption, the power consumption of each assembling only is about 10kw/h; And do not need manual knocking, and not only reduce the spoilage of bearing, also can reduce labour intensity, enhance productivity, assemble consuming time only is about 40 seconds, to be easy to promote the use of at every turn.
Below, in conjunction with the accompanying drawings and embodiments the technical characterictic of bridge hub bearing inner ring pressing machine before the utility model is further described.
