The utility model discloses a mified head is outside the processing during disc, and its strong adaptability can adapt to the outer disc of different shapes, and this mified head structural design is ingenious, and manufacturing process is simple, simultaneously the utility model discloses mified head low cost, excellent in use effect can match with rolling machine, carries out rolling to the outer disc of multiple work piece. Its effect is obvious, and the effect is showing, has good economic benefits and market value, is worth popularizing and applying.
Description
Technical field
The utility model relates to a kind of milled head and knurling machine, belongs to rolling and processing technical field.
Background technology
Rolling and processing is the processing of a kind of chipless, applies certain pressure by the rolling tools of certain forms to surface of the work.Utilize the plastic deformation of metal at normal temperatures, the nao-and micro relief of surface of the work is planished thus reaches the object changing surface structure, mechanical property, shape and size.At present, rolling and processing has been widely used in machining, milled head is as the core component in rolling and processing, its version is also varied, such as outer surface of workpiece is carried out to the milled head of roll extrusion, the milled head carrying out roll extrusion to taper hole, roll extrusion through hole, blind hole being carried out to roll extrusion are first-class.
Chinese patent literature CN2119984U discloses a kind of Universal milled head, be made up of pressure head, supporting member, bearing, little axle and supporter, the utility model uses the radial support of pressure head instead radial antifriction bearing, and the advantage of this milled head is, can cylindrical rolling, endoporus, versatility is better.But this milled head structure relative complex, processing technology is also comparatively complicated, and during for processing excircles in enormous quantities, its financial cost is higher.
Utility model content
For the deficiencies in the prior art, the utility model provides a kind of milled head, and this milled head structure is simple, and practicality is good, can adapt to different peripheries.
The technical solution of the utility model is as follows:
A kind of milled head, comprise turning rolls, roller, roller shaft and bearing, described roller is arranged on turning rolls by roller shaft, is connected between roller with roller shaft by bearing.
Preferably, be connected by two taper roll bearings in parallel between roller with roller shaft, between two taper roll bearings, be provided with adjusting pad.Benefit of this design is, two bearings in parallel are symmetrical arranged, and can strengthen milled head axially and radial bearing capacity.
Preferably, described milled head also comprises locking nut, and one end of roller shaft is fixed by locking nut.The benefit of this design is, bearing can carry out pretension by locking nut, and the size of pretension amount is adjusted by the thickness match grinding of adjusting pad.
Preferably, described turning rolls is provided with flat key.The advantage of this design is, when milled head is installed, flat key can be used for the rotation preventing milled head, plays guide effect.
Preferably, described roller is symmetrical structure.
The use procedure of this milled head is as follows:
Be installed on the knife rest of knurling machine by turning rolls one end of milled head, contacted by the roller of milled head with the periphery normal direction of workpiece to be processed, start knurling machine, milled head carries out rolling and processing to workpiece to be processed.
A kind of knurling machine, is characterized in that, comprise above-described milled head.
The beneficial effects of the utility model are:
Milled head of the present utility model is when processing excircles face, and its strong adaptability, can adapt to difform periphery; And the bearing capacity of this milled head is stronger, this milled head smart structural design, manufacturing process is simple, and the utility model milled head is with low cost simultaneously, and result of use is good, can match with knurling machine, carries out rolling and processing to the periphery of various workpieces.Obviously, Be very effective, has good economic benefit and market value, is worthy of popularization in its effect.

Detailed description of the invention
Also by reference to the accompanying drawings the utility model is described further below by embodiment, but is not limited thereto.
Embodiment 1:
As shown in Figure 1 to Figure 3, a kind of milled head, comprises turning rolls 1, roller 2, roller shaft 6 and bearing 3, and roller 2 is arranged on turning rolls 1 by roller shaft 6, is connected between roller 2 with roller shaft 3 by bearing 3.
Be connected by two taper roll bearings in parallel between roller 2 with roller shaft 6, adjusting pad 4 is provided with between two taper roll bearings, one end of roller shaft 6 is fixed by locking nut 5, bearing 3 can carry out pretension by locking nut 5, and the size of pretension amount is adjusted by the thickness match grinding of adjusting pad 4.
This roller 2 is symmetrical structure, and both sides are the inclined-plane that symmetrical expression is arranged, and are connected smoothly, as shown in Figure 3 between two inclined-planes by one section of circular arc.
Embodiment 2:
A kind of milled head, as described in Example 1, its difference is structure: in order to meet different surface of the work shapes, roller 2 is asymmetric structural design, is namely partial to the side of roller with the peak of absorption surface.
Embodiment 3:
A kind of milled head, as described in Example 1, its difference is structure: on described turning rolls 1, be provided with flat key 7.When milled head is installed, flat key can be used for the rotation preventing milled head, plays guide effect.
Embodiment 4:
A kind of knurling machine, comprises the milled head described in embodiment 3.
