Description
Technical field：
The present invention relates to floating support, is especially a kind of floating support of bearing grinder.
Background technology：
Existing floating support is using two hard alloy poles according to bearing ring diameter into 120 ° or 150 ° of angles
It is and vertical with lasso axial line to be welded on brazing on supporting head.This structure has the following disadvantages, 1, supporting head is using letter
Branch girder construction, machining accuracy are not easy to ensure, and workpiece height hour, need to use the higher magnetic pole of height；2nd, workpiece and alloy
Be point contact when pole is initial, now because contact area is small, stock removal and feed speed can not all obtain it is excessive, otherwise easily
Lasso is produced pivot burn or fulcrum incised wound lasso causes product to degrade or scrap, and processing efficiency is low and percent defective is high, and
And finally need 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 in the lump and scrapped when needing to scrap to a certain extent, is caused to waste and is increased bearing and adds
Work cost.
The content of the invention：
The technical problem to be solved by the invention is to provide a kind of easy processing, production cost is low and improves production efficiency
The floating support of bearing grinder, the floating support machining accuracy are high.
The technical solution of the present invention is to provide a kind of floating support of bearing grinder, including supporting head and fulcrum bearing,
Supporting head is connected to form cantilever beam structure by bearing pin with fulcrum bearing, and supporting head and fulcrum bearing interference fit connect, supporting head with
Bearing pin gap coordinates, and the axial movement value of supporting head is 0.02-0.03；Cooling liquid flowing channel is machined with supporting head and bearing pin,
The coolant spout coordinated with cooling liquid flowing channel is also machined with bearing pin external diameter；Supporting head is ring sector structure, in supporting head
Cambered surface interference fit has more alloy poles, and alloy pole is disposed on the outer circumference surface of supporting head intrados and alloy pole
Supporting head intrados is protruded from, alloy pole and bearing ring axis parallel, alloy pole protrude from supporting head intrados
Outer circumference surface forms circular arc concave curved surface, the circular arc concave curved surface composition supporting of each alloy pole according to the bearing-surface pre-grinding of workpieces processing
Face contact surface.
Using compared with prior art, the present invention has advantages below after above structure：Cantilever beam structure is easy to process, branch
Thickness, the bearing pin length of taking the lead are easily guaranteed that, and are suitable for the big lasso of difference in height, and lasso height can reversely pacify when smaller
Dress；The circular arc concave curved surface composition bearing surface interface of each alloy pole pre-grinding shaping, length direction maximum can reach and workpiece branch
Bearing surface is identical, and grinding dosage can obtain more greatly, and processing efficiency can greatly improve, the bearing surface interface precision after pre-grinding
Height, adhered shape lasso, surface is smooth, hardly wears, and offset would not change, and the machining accuracy of lasso has guarantor
Barrier, and the work mounting s head adapted in larger size range can be processed according to workpiece size；Grinding machine cooling liquid can be by soft
Pipe accesses the runner of supporting head and bearing pin, and the coolant spout on bearing pin can guarantee that coolant reliably flows out, to contact site
Divide and cooled down and lubricated, bearing-surface is not produced fulcrum print, and external diameter reconditioning process can be cancelled, reduce production cost；
The workpiece accuracy that the present invention processes is high, because the workpiece of processing does not need external diameter reconditioning, reduces a procedure, processing efficiency
Height, present invention is mainly used for the centerless grinding of such part such as bearer ring.
Formed preferably, supporting head is cut by annulus.Save material and artificial.
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 ± 0.01, and D is the bearing-surface diameter of workpieces processing.
Further, the bearing pin is step pin axle.
Further, the alloy pole is 4.
Brief description of the drawings：
Fig. 1 is the structural representation of the present invention.
Fig. 2 is the sectional view of the present invention.
Embodiment：
The invention will be further described with reference to the accompanying drawings and detailed description：
As shown in Figure 1-2, a kind of floating support of bearing grinder, including fulcrum bearing 1 and supporting head 2, supporting head 2 pass through platform
Rank bearing pin 3 is connected to form cantilever beam structure with fulcrum bearing 1, i.e., supporting head is located at the side setting of fulcrum bearing, supporting head 2 and supporting
The interference fit connection of seat 1, supporting head 2 coordinates with the gap of bearing pin 3, and the axial movement value of supporting head is 0.02-0.03；Supporting head
2 and bearing pin 3 in be machined with cooling liquid flowing channel, be also machined with the external diameter of bearing pin 3 with cooling liquid flowing channel coordinate coolant spout,
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 and be formed
Multiple supporting heads, supporting head intrados interference fit have 4 alloy poles 5, and alloy pole 5 is disposed on supporting head intrados
And the outer circumference surface of alloy pole protrudes from supporting head intrados, alloy pole and bearing ring axis parallel, alloy pole
The outer circumference surface for protruding from supporting head intrados forms circular arc concave curved surface 4, each alloy circle according to the bearing-surface pre-grinding of workpieces processing
The circular arc concave curved surface 4 of rod forms bearing surface interface.Preferably, alloy pole 5 protrudes from the excircle of supporting head intrados
Face forms circular arc concave curved surface according to the bearing-surface pre-grinding of workpieces processing, and pre-grinding dimensional accuracy is D ± 0.01, and D is workpieces processing
Bearing-surface diameter, carried out in advance with green silicon carbide emery wheel or skive according to work mounting s face size on internal grinder
