Abstract
The invention belongs to a novel manufacture method of a curling automobile hub bearing unit, belonging to the manufacture method of automobile spare parts and solving the defect that a bearing of a traditional automobile hub bearing unit is uniformly axially fixed in a bearing seat. The manufacture method of the curling automobile hub bearing unit comprises the following steps: firstly, processing the bearing seat into a bearing mounting cavity and a coiling ring; secondly, mounting the bearing in the bearing mounting cavity; and thirdly, using a spiral riveting machine for coiling processing. The spiral riveting machine uses a die with a vertical cross section in a reversed Y shape to vertically axially place the bearing seat on a spiral riveting machine worktable, and the die moves downwards to roll the coiling ring towards an inner cavity of the bearing seat until the coiling ring is tightly stuck to the end surface of the bearing to form a coiling loop; the end surface of the bearing and the coiling loop axially position the bearing, and the inner wall of the bearing mounting cavity radially positions the bearing. The curling automobile hub bearing unit made by adopting the method has high reliability and stability.
Description
Technical field
The invention belongs to the auto parts and components manufacture method, especially relevant with a kind of manufacture method of curling automobile hub bearing unit.
Background technology
Automobile hub bearing mainly is made up of bearing and bearing block, bearing block is a sleeve that has ring flange, bearing is installed in the bearing block and to bearing and makes axial restraint, traditional bearing fixing mode adopts the bearing outside collar end face against cooperating with jump ring, such fixed form jump ring is installed difficulty, and bearing fixing is insecure, the feasible high reliability that can't satisfy car industry requirement with the fixing automobile hub bearing of this kind fixed form.For this reason, designed a kind of novel automobile hub bearing, as Fig. 1, shown in Figure 2, bearing 1 is installed in the bearing installation cavity of bearing block 2, bearing outside collar one end is resisted against the inner face of bearing installation cavity, crimping circle 3 is set on the end face of bearing block 2 bearing is carried out axial restraint, adopt the automobile hub bearing bearing fixing of such fixed form firm, bearing can not produce circular runout or move axially in bearing block, but when carrying out crimping, the automobile hub bearing of this form must guarantee that crimping circle and bearing block sleeve are connected as a single entity, the crimping circle can be pressed against bearing outer ring, guarantee that again the bearing block sleeve can not produce deformation, otherwise bearing can produce circular runout or move axially in bearing block, automobile hub bearing is damaged easily, and reliability and stability are poor.
Summary of the invention
The object of the invention just provides the manufacture method of the new automobile hub-bearing unit of a kind of high reliability and high stability.For this reason, the present invention is by the following technical solutions:
Manufacture method of curling automobile hub bearing unit, the first step is carried out bearing block processing, bearing installation cavity coaxial of processing in the bearing block blank with axis hole, bearing installation cavity diameter is formed for the location end face of bearing axial location greater than shaft hole diameter, and the length and the bearing width of bearing installation cavity are suitable; Second step was carried out the bearing assembling, and bearing is installed in the described bearing installation cavity, and bearing one end end face is resisted against the axial location that described location end face carries out a direction, and bearing outer ring and bearing installation cavity inwall closely cooperate; It is characterized in that: adding at first step bearing block also needs at thin-walled crimping ring of the bearing block end of bearing installation cavity one side processing man-hour, this crimping ring internal diameter is slightly larger than bearing installation cavity diameter, and the crimping ring length is less than 1/2nd of bearing outer ring external diameter and inner ring external diameter difference; The 3rd step used riveter to carry out crimping processing, riveter uses vertical cross-section to be the die of the shape of falling Y, the bearing block axis is vertically placed on the riveter workbench, die moves down described crimping hoop bearing block inner chamber is carried out spreading, form the crimping circle until the end face that makes crimping circle bending 90 degree be close to described bearing, in the spreading process, die rotation under the effect of riveter axis system, die axis and bearing block axis form an angle and move along the rounding conical surface that with the bearing block axis is center line, die and crimping ring are remained contact.Crimping machines back described location end face and the crimping circle carries out axial location to bearing in the bearing installation cavity, and bearing installation cavity inwall carries out radial location to bearing.
Use the present invention can reach following beneficial effect: to adopt riveter and fall the spreading of " Y " shape die, die and crimping ring remain and contact, can effectively avoid the deformation of spreading process bottom bracket, make bearing in the bearing installation cavity, reach axial closely and radial location, make hub-bearing unit reach the requirement of high reliability and high stability, and efficient is very high, can reach 3 seconds/.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present invention is described in detail.
As Fig. 1, Fig. 2, shown in Figure 3, manufacture method of curling automobile hub bearing unit of the present invention, the first step is carried out bearing block processing, bearing block as shown in Figure 3, bearing installation cavity 4 coaxial of processing in bearing block 2 with axis hole, bearing installation cavity 4 diameters are formed for the location end face 5 of bearing axial location greater than shaft hole diameter, the length and the bearing width of bearing installation cavity 4 are suitable, be processed into a thin-walled crimping ring 6 in bearing block 2 ends of bearing installation cavity 4 one sides, crimping ring 6 internal diameters are slightly larger than bearing installation cavity 4 diameters, and crimping ring 6 length are less than 1/2nd of bearing 1 outer ring external diameter and inner ring external diameter difference; Second step was carried out the bearing assembling, and bearing 1 is installed in the bearing installation cavity 4, and as shown in Figure 4, bearing 1 one end end faces are resisted against the axial location that location end face 5 carries out a direction, and bearing 1 outer ring and bearing installation cavity 4 inwalls closely cooperate; The 3rd step used riveter to carry out crimping processing, as Fig. 5, shown in Figure 6, riveter uses vertical cross-section to be the die 7 of the shape of falling Y, bearing block 2 axis are vertically placed on the riveter workbench, die 7 moves down crimping ring 6 is carried out spreading to the inner chamber of bearing block 2, form crimping circle 3 until the end face that makes crimping ring 6 bendings 90 degree be close to bearing 1, in the spreading process, die 7 rotation under the effect of riveter axis system, the axis of die 7 axis and bearing block 2 forms an angle and is that the rounding conical surface of center line moves along the axis with bearing block 2, die 7 and crimping ring 6 are remained to be contacted, crimping machines back location end face 5 and 3 pairs of bearings 1 of crimping circle carry out axial location in bearing installation cavity 4, and the inwall of bearing installation cavity 4 carries out radial location to bearing 1.
Adopt the inventive method, die and crimping circle remain and contact, can effectively avoid the deformation of spreading process bottom bracket, make bearing in the bearing installation cavity, reach axial closely and radial location, make hub-bearing unit reach the requirement of high reliability and high stability, and it is very high to make efficient, can reach 3 seconds/.
