Abstract
The invention relates to an angular contact ball bearing flexible assembly mold with a fore shaft on an inner ring. The angular contact ball bearing flexible assembly mold comprises a mandrel, a positioning block, springs and a base; the mandrel comprises a guide column, a guide surface is arranged on the upper edge of the guide column, and the lower end of the guide column is fixed on a limiting platform; the upper end surface of the positioning block comprises a positioning platform, and a positioning groove is arranged on an outer ring of the positioning platform; the base is a hollow cylinder with an open upper end, a middle hollow part of the base is an unthreaded hole, and the springs are arranged in the unthreaded hole; the mandrel is arranged on the upper part of the springs; the positioning block sleeves the mandrel; the outer side of the positioning block is connected to the base. The angular contact ball bearing flexible assembly mold is simple in structure and easy to machine; a remarkable effect for assembling an angular contact ball bearing with the fore shaft on the inner ring can be realized; in the assembling process, a step for mixing vaseline is canceled, so that the working procedure is reduced, a great amount of vaseline is saved, the cost is reduced, and the assembling efficiency is greatly improved.
Description
Technical field
The invention belongs to bearing machining, mounting technology field, especially relate to a kind of angular contact ball bearing elasticity assembling mould of inner ring band fore shaft.
Background technique
Known, for inner ring with fore shaft angular contact ball bearing, conventionally the method adopting at present in the time assembling is: first on heating plate, heat outer ring, in the process of waiting for outer ring intensification, the steel ball that scribbles vaseline is packed in the pocket hole of retainer, take off the outer ring after heating, be enclosed within the outside with the retainer of steel ball, finally pack inner ring into.
The problem of the appearance of the method has: first, must with vaseline, steel ball be fixed in the pocket hole of retainer, fall ball when preventing from assembling.But because the space of bearing is less, supporting surface is partially narrow, and vaseline will melt in the time running into the outer ring of higher temperature, is not enough to the steel ball of adhering, thus still there is ball phenomenon, thus efficiency of assembling is affected; And use vaseline not only to cause vaseline waste, and be unfavorable for the cost of the company of saving, and be difficult for cleaning up in the time that the bearing completed products in later stage cleans, have to repeatedly clean, thereby have a strong impact on the manufacturing efficiency of bearing;
Secondly, because vaseline melts in the time running into high temperature outer ring, will make like this outer ring that temperature is higher organize contraction suddenly, cause the outer ring that originally need to add thermal expansion to meet again cold contraction suddenly, do not have the effect of due amplification outer ring size, thereby pressing bearing is affected, even can make steel ball under the effect of the outer ring of up-sizing, not scratch completely, and then affect vibration and the noise of bearing and even the working life of bearing.
Summary of the invention
?in order to overcome the deficiency in background technique, the invention discloses a kind of angular contact ball bearing elasticity assembling mould of inner ring band fore shaft, can realize convenient, the assembling fast of the angular contact ball bearing of internal astragal fore shaft according to the present invention.
In order to realize described goal of the invention, the present invention adopts following technological scheme:
An angular contact ball bearing elasticity assembling mould for inner ring band fore shaft, described assembling mould comprises mandrel, positioning block, spring and base; Described mandrel comprises a guide post, and the upper end-face edge of guide post arranges guide surface, and the lower end of guide post is fixed on limit dais; The upper end of described positioning block comprises a positioning table, and the outer ring of positioning table arranges locating slot; Described base is the uncovered hollow cylinder in upper end, and middle hollow part is unthreaded hole, and spring is placed in unthreaded hole; Described mandrel is positioned at spring top; Positioning block is enclosed within mandrel outside; Outside and the base of positioning block are fixed.
Guide surface is used for guiding the steel ball in retainer to enter in the pocket hole of retainer, and limit dais is used for limiting mandrel motion upwards.
Positioning table is for placing retainer, and locating slot is that screw column is to be used for fixing base for placing bearing outer ring.
The outer ring of positioning block of the present invention arranges screw column, and the tapped hole matching with screw column is set on the inwall of base, and base and positioning block are fixed.
Guide surface of the present invention is intilted inclined-plane.
The material of assembling mould of the present invention can be selected 45 steel or aluminium.
Owing to having adopted technique scheme, the present invention has following beneficial effect: this invention is simple in structure, easily processing, internally the angular contact ball bearing of astragal fore shaft be equipped with significant positive role, in assembly process, remove and sneaked into vaseline operation, reduced working procedure, and saved a large amount of vaseline, thereby both provided cost savings, also increased substantially efficiency of assembling.
In addition, assembling initially,, assembling mould must be placed on heating plate and heat in the lump when heating the outer ring, in the process of assembling, due to the conduction of heat of outer ring, assembling mould without heating again, thereby saved the energy.

Embodiment
Explanation the present invention that can be detailed by the following examples, discloses object of the present invention and is intended to protect all technological improvements in the scope of the invention.
As shown in accompanying drawing 1 ~ 5:
The angular contact ball bearing elasticity assembling mould of inner ring band fore shaft of the present invention comprises mandrel 1, positioning block 2, spring 3, base 4; Described mandrel 1 comprises a guide post 1b, and the upper end-face edge of guide post 1b arranges guide surface 1a, and described guide surface 1a is intilted inclined-plane.The lower end of guide post 1b is fixed on limit dais 1c; The upper end of described positioning block 2 comprises a positioning table 2a, and the outer ring of positioning table 2a arranges locating slot 2b; Described base 4 is the uncovered hollow cylinder in upper end, and middle hollow part is unthreaded hole 4b, and spring 3 is placed in unthreaded hole 4b; Described mandrel 1 is positioned at spring 3 tops; Positioning block 2 is enclosed within mandrel 1 outside; The outside of positioning block 2 and base 4 are fixing.
