Branch girder construction, machining accuracy be not easy to ensure, and when workpiece height is small, need to use higher-height magnetic pole；2nd, workpiece and alloy
For point contact when pole is initial, at this time since contact area is small, stock removal and feed speed cannot all obtain it is excessive, otherwise easily
Lasso is made, which to generate pivot burn or fulcrum incised wound lasso, causes product to degrade or scrap, and processing efficiency is low and high rejection rate, and
And it finally needs to remove fulcrum print；3rd, contact point with processing number of packages increase gradually wear out into a circular arc camber, cause work
The offset of part changes, if adjusted not in time, the raceway groove of lasso or the circularity of raceway or external radius wall thickness will be made poor
It is deteriorated；4th, the abrasion of alloy pole is needed chord to take the lead together and scrapped when needing to scrap to a certain extent, is caused to waste and is increased bearing and adds
Work cost.
Utility model content：
Technical problem to be solved in the utility model be to provide a kind of easy processing, production cost it is low and improve production effect
The floating support of the bearing grinder of rate, the floating support high precision machining.
The technical solution of the utility model is to provide a kind of floating support of bearing grinder, including supporting head and branch
Bearing, supporting head are connected to form cantilever beam structure with fulcrum bearing by axis pin, and supporting head is connected with fulcrum bearing interference fit, supporting
Head and axis pin clearance fit, and the axial movement value of supporting head is 0.02-0.03mm；Coolant is machined in supporting head and axis pin
Runner is also machined with the coolant spout with cooling liquid flowing channel cooperation on axis pin outer diameter；Supporting head is ring sector structure, is supported
Head intrados interference fit has more alloy poles, and alloy pole is disposed on the outer circle of supporting head intrados and alloy pole
Circumferential surface protrudes from supporting head intrados, and alloy pole and bearing ring axis parallel, alloy pole protrude from supporting head inner arc
The outer circumference surface in face forms circular arc concave curved surface, the circular arc concave curved surface composition of each alloy pole according to the bearing-surface pre-grinding of workpieces processing
Bearing surface interface.
Using compared with prior art, the utility model has the following advantages after more than structure：Cantilever beam structure is easy to add
Work, supporting head thickness, axis pin length are easily guaranteed that, and are suitable for the big lasso of difference in height, can be anti-when lasso height is smaller
To installation；Each molding circular arc concave curved surface composition bearing surface interface of alloy pole pre-grinding, length direction maximum can reach and work
Part bearing-surface is identical, and grinding dosage can obtain bigger, and processing efficiency can greatly improve, the bearing surface interface essence after pre-grinding
Degree is high, and adhered shape lasso, surface is smooth, hardly wears, and offset would not change, and the machining accuracy of lasso has
It ensures, and the work mounting s head adapted in larger size range can be processed according to workpiece size；Grinding machine cooling liquid can pass through
Hose accesses the runner of supporting head and axis pin, and the coolant spout on axis pin can guarantee that coolant reliably flows out, to contact
Part is cooled down and is lubricated, and bearing-surface is made not generate fulcrum print, and can cancel outer diameter reconditioning process, and reduction is produced into
This；The workpiece accuracy of the utility model processing is high, since outer diameter reconditioning is not required in the workpiece of processing, reduces a procedure, adds
Work is efficient, and the utility model is mainly used for the centerless grinding of such part such as bearer ring.
It is formed preferably, supporting head is cut by annulus.Save material and manually.
Preferably, alloy pole protrudes from the outer circumference surface of supporting head intrados according to the bearing-surface pre-grinding of workpieces processing
Circular arc concave curved surface is formed, pre-grinding dimensional accuracy is D ± 0.01mm, and D is the bearing-surface diameter of workpieces processing.
Further, the axis pin is step pin axle.
Further, the alloy pole is 4.
Description of the drawings：
Fig. 1 is the structure diagram of the utility model.
Fig. 2 is the sectional view of the utility model.
Specific embodiment：
The utility model is described in further detail with reference to the accompanying drawings and detailed description：
As shown in Figs. 1-2, a kind of floating support of bearing grinder, including fulcrum bearing 1 and supporting head 2, supporting head 2 passes through platform
Rank axis pin 3 is connected to form cantilever beam structure with fulcrum bearing 1, i.e., supporting head is located at the one side setting of fulcrum bearing, supporting head 2 and supporting
1 interference fit connection of seat, supporting head 2 and 3 clearance fit of axis pin, and the axial movement value of supporting head is 0.02-0.03mm；Supporting
First 2 and axis pin 3 in be machined with cooling liquid flowing channel, be also machined on 3 outer diameter of axis pin with cooling liquid flowing channel cooperation coolant flow out
Slot, to ensure that coolant reliably flows out；Supporting head 2 is ring sector structure, and for convenience of processing, supporting head 2 can be cut by annulus
Multiple supporting heads are formed, supporting head intrados interference fit there are 4 alloy poles 5, and alloy pole 5 is disposed in supporting head
The outer circumference surface of cambered surface and alloy pole protrudes from supporting head intrados, alloy pole and bearing ring axis parallel, alloy
The outer circumference surface that pole protrudes from supporting head intrados forms circular arc concave curved surface 4 according to the bearing-surface pre-grinding of workpieces processing, each to close
