Abstract
The utility model relates to a bearing press fitting device of a steering device housing, and belongs to the technical field of automobile steering devices. The bearing press fitting device is composed of a pressure head, a central spindle, a supporting seat and a bottom board, wherein the central spindle is fixedly arranged on the bottom board through an inner hexagon screw; the supporting seat is sleeved at the bottom of the central spindle through a supporting spring; and the pressure head is movably sleeved at the top of the central spindle. The bearing press fitting device is simple in structure and easy to process and manufacture, the press fitting precision can be ensured without special equipment investment, and the coaxiality requirement of bearings at two positions can be ensured, so that the device solves the problems that the existing press fitting auxiliary tool is difficult to ensure the coaxiality of bearings at two positions to cause bad assembling precision of a gearing device assembly so that the reject or repair rate of steering device products is relatively high and the enterprise benefit is influenced to a certain degree. The bearing press fitting device is quick in production rhythm and high in press fitting quality, so that unnecessary rework and quality loss are reduced, and one-time pass rate of the steering device products is improved.
Description
Technical field
The utility model relates to a kind of bearing press mounting device of steering gear housing, belongs to the automobile steering device technology field.
Background technology
Existing automobile gear rack-type steering gear is when assembling, and the steering gear housing domestic demand press-fits two place's bearings, i.e. housing middle (center) bearing and housing lower bearing.Because of steering gear belongs to the vehicle key parts, coaxial accuracy to two place's bearings in the steering gear housing is had relatively high expectations, can cause housing bearing position internal diameter and bearing outside diameter to cut edge as no guiding in the pressing bearing process, cause two place's bearing disalignments, influence the steering gear assembly precision.Because the reasons in structure of steering gear product, the special-purpose accessory that existing steering gear housing bearing press mounting is adopted, be difficult to guarantee the axiality of two place's bearings, cause the assembly precision of steering assembly poor, thereby cause scrapping or reprocessing higherly of steering gear product, occur not only wasting the dismounting cost of labor but also cause the product quality loss after this type of phenomenon.Affect the benefit of enterprise to a certain extent.
Summary of the invention
The purpose of this utility model is: provide a kind of simple in structure, easily processing and manufacturing, and can guarantee to press-fit precision, to solve the existing axiality that accessory is difficult to guarantee two place's bearings that press-fits, cause the assembly precision of steering assembly poor, thereby cause scrapping or reprocessing higherly of steering gear product, affect the bearing press mounting device of the steering gear housing of performance of enterprises problem to a certain extent.
The technical solution of the utility model is:
A kind of bearing press mounting device of steering gear housing, it is made of pressure head, mandrel, supporting seat and base plate, it is characterized in that: be installed with mandrel by soket head cap screw on the base plate, the mandrel bottom is set with supporting seat by support spring, the mandrel top movable is set with pressure head, described mandrel is stepped, and described pressure head is the T font.
The beneficial effects of the utility model are:
1, the bearing press mounting apparatus structure of this steering gear housing is simple, and easily processing and manufacturing need not the special equipment input and can guarantee to press-fit precision;
2, the bearing press mounting device of this steering gear housing can press-fit simultaneously to two place's bearings on the steering gear housing, and productive temp is faster;
3, the bearing press mounting device of this steering gear housing can effectively improve part and press-fits quality, reduces unnecessary doing over again and mass loss.
Description of drawings
Fig. 1 is an apparatus structure schematic diagram of the present utility model;
Fig. 2 is a working state schematic representation of the present utility model.
Among the figure: 1, pressure head, 2, mandrel, 3, supporting seat, 4, support spring, 5, base plate, 6, soket head cap screw, 7, steering gear housing (workpiece), 8, the housing middle (center) bearing, 9, the housing lower bearing.
The specific embodiment
The bearing press mounting device of this steering gear housing is made of pressure head 1, mandrel 2, supporting seat 3 and base plate 5.Be installed with stair-stepping mandrel 2 by soket head cap screw 6 on the base plate 5, mandrel 2 bottoms are set with supporting seat 3 by support spring 4, and mandrel 2 top movable are set with the pressure head 1(of pressure oral area band chamfering referring to accompanying drawing 1).
The bearing press mounting device of this steering gear housing is when press-fiting work, at first housing lower bearing 9 is sleeved on the mandrel 2 in the supporting seat 3, then steering gear housing 7 being the inversion shape is sleeved on the mandrel 2, and the cylindrical of housing lower bearing 9 is cooperated with the endoporus of steering gear housing 7,3 pairs of steering gear housings of supporting seat 7 are formed support.After above-mentioned steps is finished, housing middle (center) bearing 8 is sleeved on the mandrel 2 of steering gear housing 7 tops again, loads onto pressure head 1 then, can start aerostatic press and press-fit (referring to accompanying drawing 2).
Press-fit in the process, pressure head 1 is descending at the effect lower edge of aerostatic press mandrel 2, thereby housing middle (center) bearing 8 is press-fited to steering gear housing 7.Because pressure head 1 is the T font, after housing middle (center) bearing 8 is press-fit into place, steering gear housing 7 is descending at the effect lower edge of pressure head 1 mandrel 2, steering gear housing 7 is in descending process, progressively compress supporting seat 3, thereby make housing lower bearing 9 from supporting seat 3 interior emersions, and be assembled in the endoporus of steering gear housing 7, press-fit thereby finish along with the descending power of steering gear housing 7.
The bearing press mounting apparatus structure of this steering gear housing is simple, easily processing and manufacturing, need not the special equipment input and can guarantee to press-fit precision, and can guarantee the axiality requirement of two place's bearings, solved the existing axiality that accessory is difficult to guarantee two place's bearings that press-fits, cause the assembly precision of steering assembly poor, thereby cause scrapping or reprocessing higherly of steering gear product, affect the problem of the performance of enterprises to a certain extent.The productive temp of the bearing press mounting device of this steering gear housing is fast; Press-fit the quality height, reduced unnecessary doing over again and mass loss, effectively improved the disposable qualification rate of steering gear product.
