Description
Technical field
The utility model relates to bearing parts manufacturing technology field, particularly relates to raceway position measurement mechanism in a kind of large-scale self-aligning roller bearing Vehicle Processing.
Background technology
In oversize self-aligning roller bearing Vehicle Processing at present, raceway position model is " reaping hook " shape, because being subject to the restriction of the wire cutting machine tool range of work, can only be made into and ride over the fixedly model of the interior raceway position of end surface measurement on one side, due to the inside and outside poor existence of inner ring end face, will affect the accuracy of measurement, such as FD-240/630/W33/HC, this inner ring raceway height is more than 3 times of end surface thickness, if end face is inside and outside poor is 0.05mm, with above-mentioned model, measure and will cause raceway two ends diameter phase mutual deviation 0.30mm so, make to grind processing difficulties and raceway depth of hardening zone is inconsistent, affect bearing serviceable life.
Utility model content
The technical problems to be solved in the utility model is, raceway position measurement mechanism in a kind of large-scale self-aligning roller bearing Vehicle Processing is provided, and this apparatus structure is simple, easy to make, and cost is low, can improve the machining precision of bearing inner race, improves bearing serviceable life.
The technical scheme adopting is:
A raceway position measurement mechanism in large-scale self-aligning roller bearing Vehicle Processing, comprises substrate, position model and connecting clamp.Described substrate is rectangular template, the measurement face of position model by with the circular arc that matches of survey bearing inner race, connecting clamp is provided with the slotted eye matching with substrate and the slotted eye matching with position model.Described connecting clamp is two, by the slotted eye matching with substrate, be sleeved on substrate upper end, and with the screw fastening of one end, position model packs in the slotted eye matching with position model of upper and lower connecting clamp, with its basal plane, be mounted on the vertical basal plane that substrate precision is higher, the connecting hole that passes connecting clamp and position model by screw is fastening, raceway position measurement mechanism in forming.
On the substrate body of aforesaid substrate, be milled with the strip hole of conveniently controlling with weight reduction.
The circular arc measurement face of above-mentioned position model is set as is convenient to 30 ° of chamferings that gap is observed.
The utility model leans against on the whole end face of inner ring because of substrate, can avoid the inside and outside poor impact that raceway position is measured of inner ring end face, improves bearing machining precision and bearing serviceable life.Substrate, connecting clamp are general part, and position model can be processed on small-sized wire cutting machine tool, and whole measurement mechanism is simple in structure, good manufacturability, and cost is low.

Embodiment
A raceway position measurement mechanism in large-scale self-aligning roller bearing Vehicle Processing, comprises substrate 1, position model 3 and connecting clamp 2.Described substrate 1 is rectangular template, can on rectangle plane grinding machine, grind processing, and precision is higher; On its substrate body, be milled with strip hole 5, conveniently control and weight reduction, substrate is general part, reduces production costs.The small-sized wire cutting machine tool cutting of position model 3 use, convenient processing, the measurement face 6 of position model 3 for the circular arc that matches of survey bearing inner race, its circular arc measurement face is set as 30 ° of chamferings being convenient to gap observation, near basal plane position, there are being two through holes, for connecting.Connecting clamp 2 is provided with the slotted eye 7 matching with substrate 1 and the slotted eye 8 matching with position model 3.Described connecting clamp 2 is two, by the slotted eye 7 matching with substrate, be sleeved on substrate 1 upper end, and with the screw fastening of one end, position model 3 packs in the slotted eye 8 matching with position model of upper and lower connecting clamp 2, with its basal plane, be mounted on the vertical basal plane that substrate precision is higher, the connecting hole that passes connecting clamp and position model by screw is fastening, raceway position measurement mechanism in forming.
During use, with two connecting clamps 2, be enclosed within substrate 1 one end, screw is through the connecting hole of connecting clamp 2 and position model 3 and tighten, then tightens connecting clamp 2 end screws it is fixed on substrate 1, is assembled into measurement mechanism.Substrate 1 reference field is attached on inner ring 4 end faces, and slowly sliding substrate makes position model contact with raceway, and the goodness of fit of observation place model and raceway can determine that whether raceway position is qualified.
