Summary of the invention
Object of the present invention is providing a kind of adjustable grinding tool, and this grinding tool may be used for the brearing bore attrition process of different size, and versatility is good.
For achieving the above object, base case of the present invention is as follows:
Adjustable grinding tool, comprise conic mandrel bar, grinding sleeve, the first compressing member and the second compressing member, be enclosed within outside conic mandrel bar outside described grinding sleeve, and grinding sleeve and conic mandrel bar cone match, described grinding sleeve is offered the breach running through grinding sleeve along grinding sleeve length direction; Described conic mandrel bar two ends are provided with thread segment, and described first compressing member comprises the first clamp nut and the first packing ring, and the first gasket sleeve is on the thread segment of plug one end and offset with grinding sleeve one end, and described first clamp nut compresses the first packing ring; Described second compressing member comprises the second clamp nut and the second packing ring, and the second gasket sleeve is on the thread segment of the plug other end and offset with the grinding sleeve other end, and described second clamp nut compresses the second packing ring.
The principle of this programme: according to the size of the endoporus of bearing to be ground, first clamp nut and the second clamp nut respectively, the adjustment position of grinding sleeve on conic mandrel bar, owing to grinding sleeve being offered the breach running through grinding sleeve along grinding sleeve length direction, so the diameter of grinding sleeve just can be regulated, after grinding sleeve diameter adjustment, by the first clamp nut and the locking of the second clamp nut, finally conic mandrel bar one end is arranged on lathe, coat grinding agent at grinding sleeve outer surface, namely can be used for the brearing bore grinding corresponding size.
The advantage of this programme is: in this programme, grinding sleeve is offered the breach running through grinding sleeve along grinding sleeve length direction, grinding sleeve is then outer to be enclosed within conic mandrel bar, so the external diameter of grinding sleeve can regulate according to the size of brearing bore to be ground, thus be suitable for carrying out attrition process to the brearing bore of the bearing of different size, versatility is high.
Prioritization scheme 1, to the further optimization of base case, described grinding sleeve outer wall is offered the bar-shaped trough that at least one is arranged along grinding sleeve length direction.In use procedure, need to coat grinding agent outside grinding sleeve, in this programme, in bar-shaped trough, can grinding agent be stored, so just do not need frequently on grinding sleeve, to be coated with grinding agent.
Prioritization scheme 2, to the further optimization of prioritization scheme 1, the degree of depth of described bar-shaped trough is less than 1/3rd of grinding sleeve wall thickness.When the degree of depth of bar-shaped trough is in above-mentioned scope, can ensure the intensity of grinding sleeve on the one hand, on the other hand, the grinding agent stored in bar-shaped trough can use long period of time.
Prioritization scheme 3, to the further optimization of base case, the outer rim bevelling at described grinding sleeve two ends, described first packing ring, the second packing ring are provided with the inclined-plane coordinated with described bevelling.After the first packing ring, the second packing ring compress by the first clamp nut, the second clamp nut respectively, the first packing ring, the second packing ring and grinding sleeve two ends contact of incline plane are also compressed, the mode seal face of above-mentioned contact of incline plane greatly, stressed evenly.
Prioritization scheme 4, to base case, the further optimization of any one of prioritization scheme 1-3, is provided with cooling chamber in described conic mandrel bar, the thread segment of conic mandrel bar one end is provided with the feed pathway be communicated with cooling chamber, and thread segment is communicated with outside cooling fluid by swivel joint.In the process of grinding, grinding sleeve can produce a large amount of heats, and heat persistent accumulation can cause brearing bore to expand with heat and contract with cold, thus affect machining accuracy, this programme passes into cooling fluid to the cooling chamber in conic mandrel bar, so just can absorb the heat produced in process of lapping, thus ensures machining accuracy.
Accompanying drawing explanation
Fig. 1 is the structural representation of the adjustable grinding tool embodiment 1 of the present invention;
Fig. 2 is the sectional view in A-A direction in Fig. 1.
Detailed description of the invention
Below by detailed description of the invention, the present invention is further detailed explanation:
