Abstract
The utility model relates to a honing wheel device for conducting finishing machining for the outer circular surface of a workpiece. The honing wheel device is characterized by comprising a honing wheel, a support, a cutter bar and a spring; the honing wheel is arranged on a wheel shaft; two ends of the wheel shaft are respectively connected with a guide bar; the spring is arranged between the guide bar and a sliding sleeve embedded onto the support; and the support is integrally connected with the cutter bar through a locknut. The outer diameter of the honing wheel has a pillow-shaped arc section contour, the diameter of the pillow-shaped arc section is larger than that of the workpiece, an included angle is arranged between a working shaft of the wheel shaft and a rotary axis of the workpiece, and the included angle ranges from 25 degrees to 60 degrees. The honing wheel device has the advantages that after the device is installed, lathes can simultaneously finish the process of rough turning, finish turning and fine grinding without mounting the workpiece onto grinders. Moreover, the surface roughness of the workpiece can reach more than Ra 0.4, the processing cycle of the workpiece is obviously shortened, and production cost is also reduced.
Description
Technical field
The utility model relates to field of machining, relates in particular to the honing wheel device that the excircle of workpiece face is carried out polishing processing.
Background technology
Honing is a kind of workpiece to be carried out one of polishing method for processing.Its principle and essence are to utilize the honing wheel of fine granularity abrasive material, under the state that floats, surface of the work are carried out the low speed grinding.It can improve workpiece size and geometrical precision and reduce workpiece surface roughness, circularity can reach 0.0005～0.005mm after the honing, dimensional accuracy can reach 0.005～0.025mm, and surface roughness can reach Ra0.4～0.05 μ m, and does not have burn, embedding sand and crackle; Honing at present is mainly used in the polishing processing of large aperture deep hole.
At mechanical processing industry, periphery polishing to workpiece mainly is to be undertaken by cylindrical grinder, but also to pass through the level of surface roughness that multiple working procedures such as corase grind, correct grinding, polishing just can reach Ra0.4～0.05 μ m, and cause the workpiece process-cycle long, production cost can fall yet.
Summary of the invention
The utility model provides a kind of honing wheel device that is applied on the lathe, realizes the purpose that not only reaches desirable surface roughness but also reduce manufacturing procedure.
The utility model is achieved through the following technical solutions:
The honing wheel device comprises honing wheel, support, knife bar, spring, and honing wheel is arranged on the wheel shaft, and each is connected the wheel shaft two ends with guide rod, is provided with spring between guide rod and the sliding sleeve, and sliding sleeve is embedded on the support, and support and knife bar link together by locking nut.
Described honing wheel external diameter has pincushion segmental arc profile.Described pincushion segmental arc diameter should be more than or equal to diameter of work.
Described wheel shaft working shaft and workpiece rotation have angle.Described angle is 25～60 °.
Compared with prior art, the beneficial effects of the utility model are: after this device is installed, lathe can be rough turn, finish turning, correct grinding machine together, do not need to go up again grinding machine, and surface roughness can reach more than the Ra0.4, the workpiece process-cycle obviously shortens, and production cost has also lowered.

The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
See Fig. 1, the honing wheel device, comprise honing wheel 1, support 2, knife bar 4, spring 5, honing wheel 1 is arranged on the wheel shaft 12, each is connected wheel shaft 12 two ends with guide rod 6, be provided with spring 5 between guide rod 6 and the sliding sleeve 7, sliding sleeve 7 is embedded on the support 2, and support 2 links together by locking nut 3 with knife bar 4.
In order to guarantee when the honing, honing wheel 1 cylindrical can workpiece pressing 10 cylindricals, improve honing efficient, and honing wheel 1 external diameter has pincushion segmental arc profile.Described pincushion segmental arc diameter should be more than or equal to workpiece 10 diameters.
See Fig. 2,, realize honing effect, also will apply 100-200N contact pressure workpiece 10 external diameters for making honing wheel 1 near workpiece 10 cylindricals.This device passes through the thrust of the compression realization of two springs 5 to workpiece.
See Fig. 3, wheel shaft 12 working shafts 9 have angle α with workpiece 10 rotations.Angle α is generally 25～60 °.Learn by diagram method: honing peripheral speed Vc=honing wheel speed Ve/cos α (m/min), lathe reciprocating speed Va=Vesin α (m/min), Vc is low for the honing peripheral speed, and reciprocating speed Va height can increase the α angle, makes honed surface become coarse.The α angle should be more greatly during the thick top gem of a girdle-pendant, and generally getting the α angle is 30 °～60 °; α wants at the angle littler during the essence top gem of a girdle-pendant, and generally getting α is 25 °～35 °.The technological parameter of common grinding equipment: honing surplus: 2ap=0.05～0.1mm; Workpiece 10 (or honing bistrique) speed Vc=50-80m/min: the amount of feeding: f=0.2～1mm/r; Contact pressure: 100-200N.When workpiece 10 diameters of same segmental arc size honing wheel 1 honing became big, angle also needed to increase; Otherwise angle also diminishes; But will be in angular range; If exceed angular range, just need to change the honing wheel 1 of another segmental arc size.When regulating angle, unclamp locking nut 3 earlier, after being aligned workpiece 10 cylindricals, honing wheel 1 cambered surface determines angle, tighten locking nut 3 then, fixed angle carries out honing.As on support 2, dial being installed, on knife bar 4, pointer is installed, the angle in the time of so just can knowing honing easily whether in prescribed limit, workpiece 10 external diameters of the honing wheel 1 of every kind of segmental arc size in can corresponding certain limit.
See Fig. 4, pincushion segmental arc diameter calculates: this pincushion segmental arc is an oval part, and this ellipse is consistent with 25 °～60 ° angle cross sectional shapes of workpiece 10 diameters.Knife bar 4 is clamped on the knife rest 11.
