Abstract
The utility model discloses a conical nail jacket spinning necking-down device in order to solve the problems that in the prior art, a conical nail jacket spinning necking-down method is low in efficiency and long in consumed time, and the quality can not be guaranteed easily. The conical nail jacket spinning necking-down device comprises a pressing block and a spinning assembly, wherein the diameter of the cylindrical pressing block is matched with the maximum diameter of a conical jacket, and a conical hole matched with a lathe centre is formed in the end face of the cylindrical pressing block; the spinning assembly comprises a spinning rod, a step shaft pin, a roller, a bearing, a bearing end cover, a bush and a nut, wherein a fork opening is formed in the front end of the spinning rod, and the bearing is pressed in the inner step of the roller and arranged on the step shaft pin in a sleeved mode; the bearing end cover is fixed to the end face of the roller through screws so that the roller, the bearing and the bearing end cover can be integrated. The conical nail jacket spinning necking-down device has the technical advantages of being accurate and reliable in compression positioning, high in efficiency and good in quality. The necking-down outer diameter and the necking-down angle can be freely adjusted, and the conical nail jacket spinning necking-down device is applicable to various specifications of conical nail jacket spinning neck-down parts. Besides, the conical nail jacket spinning necking-down device is simple in structure, convenient to operate and low in cost.
Description
Technical field
The utility model relates to a kind of cone-shaped nail overcoat spinning reducing technology, specially refers to a kind of cone-shaped nail overcoat spinning reducing device.
Background technology
In some large-sized mechanical components, need to follow closely the taper sheath that increases another kind of metal material on bar at metal conic, to meet the particular/special requirement of its use.And, require the size and shape of taper sheath to mate completely with cone-shaped nail, and taper sheath inner surface can be fitted with cone-shaped nail intimate.Because the demand of this type component is less, and specification is more, prior art adopts artificial mode to carry out the reducing of cone-shaped nail overcoat spinning, place the big or small cylindrical metal sleeve matching with cone-shaped nail maximum outside diameter at cone-shaped nail bar, by the mode of manually beaing, make cylindrical metal sleeve be deformed into taper shape, and ensure that size and shape and the cone-shaped nail of taper sheath match, taper sheath inner surface can be fitted with cone-shaped nail intimate.The quality of the taper sheath of this method manufacture all relies on operator's experience and sensation.The problems such as obviously, it is low that prior art cone-shaped nail overcoat spinning reducing method exists efficiency, many and difficult quality guarantee consuming time.
Summary of the invention
Low for solving the efficiency that prior art cone-shaped nail overcoat spinning reducing method exists, the problems such as many and difficult quality guarantee consuming time, the utility model proposes a kind of cone-shaped nail overcoat spinning reducing device.The utility model cone-shaped nail overcoat spinning reducing device comprises compact heap and spinning assembly; The diameter of cylindrical compact heap and taper sheath maximum gauge match, and are provided with the bellmouth matching with lathe thimble at its end face; Spinning assembly comprises spinning rod, step pivot pin, roller, bearing, bearing (ball) cover, lining and nut, and spinning nose is provided with prong, is horizontally arranged with step pivot pin at prong; Bearing press mounting is in the interior step of roller and be sleeved on step pivot pin; Bearing (ball) cover is fixed by screws in roller end face becomes one roller, bearing and bearing (ball) cover; Nut spinning is in step pivot pin termination and by lining, roller is fixed in prong.
The useful technique effect of the utility model cone-shaped nail overcoat spinning reducing device be compression set accurately and reliably, efficiency is higher, quality is better.Reducing external diameter and angle can regulate arbitrarily, adapt to the cone-shaped nail overcoat spinning reducing of many specifications.And, simple in structure, easy to operate, with low cost.
Brief description of the drawings
Accompanying drawing 1 is the structural representation of the utility model cone-shaped nail overcoat spinning reducing device.
Below in conjunction with the drawings and specific embodiments, the utility model cone-shaped nail overcoat spinning reducing device is further described.
Detailed description of the invention
Accompanying drawing 1 is the structural representation of the utility model cone-shaped nail overcoat spinning reducing device, and in figure, l is compact heap, 2 is spinning assembly, and 3 is cone-shaped nail, and 4 is lathe dog, 5 is lathe thimble, and 6 is taper sheath, and 21 is spinning rod, 22 is step pivot pin, 23 is roller, and 24 is bearing, and 25 is bearing (ball) cover, 26 is lining, and 27 is nut.As seen from the figure, the utility model cone-shaped nail overcoat spinning reducing device comprises compact heap 1 and spinning assembly 2; The diameter of cylindrical compact heap 1 and taper sheath maximum gauge match, and are provided with the bellmouth matching with lathe thimble at its end face; Spinning assembly 2 comprises spinning rod 21, step pivot pin 22, roller 23, bearing 24, bearing (ball) cover 25, lining 26 and nut 27, and spinning rod 21 front ends are provided with prong, is horizontally arranged with step pivot pin 22 at prong; Bearing 24 is fitted in the interior step of roller 23 and is sleeved on step pivot pin 22; Bearing (ball) cover 25 is fixed by screws in roller 23 end faces becomes one roller 23, bearing 24 and bearing (ball) cover 25; Nut 27 spinnings are in step pivot pin 23 terminations and by lining 26, roller 23 is fixed in prong.In the specific implementation, cone-shaped nail is clamped on lathe dog, the cylindrical jacket for the treatment of rotary press modelling is sleeved on to the cone-shaped end place of cone-shaped nail, place after the utility model cone-shaped nail overcoat spinning reducing device compact heap, hold out against with lathe thimble.Because diameter and the taper sheath maximum gauge of the cylindrical compact heap of the utility model cone-shaped nail overcoat spinning reducing device match, be provided with the bellmouth matching with lathe thimble at its end face, therefore,, after lathe thimble compresses, can ensure accurate location and the firm laminating of cylindrical jacket.The utility model cone-shaped nail overcoat spinning reducing device spinning assembly is fixed on lathe saddle, adjust the periphery of roller and the angle on cone-shaped nail inclined-plane, two faces are parallel to each other, open lathe spindle, cone-shaped nail rotates under the drive of lathe dog, manipulation lathe saddle, makes the cylindrical of spinning component roller wheel contact gradually cylindrical jacket outer surface.Under the effect of frictional force, roller will together rotate with cylindrical jacket, because the periphery of roller is identical with the angle of inclination on cone-shaped nail inclined-plane, cylindrical jacket will be out of shape gradually.Because lathe saddle can be in horizontal and vertical both direction motion, can adjust easily the amount of feeding of roller cylindrical and overcoat outer surface contact position and roller, make cylindrical jacket be deformed into uniformly taper shape, and, the size and shape and the cone-shaped nail that effectively ensure taper sheath match, and taper sheath inner surface can be fitted with cone-shaped nail intimate.Can adjust arbitrarily due to the periphery of roller and the angle on cone-shaped nail inclined-plane, the amount of feeding of roller also can be adjusted arbitrarily, and the external diameter of its reducing and angle can regulate arbitrarily, adapt to the cone-shaped nail overcoat spinning reducing of many specifications.
Obviously, the useful technique effect of the utility model cone-shaped nail overcoat spinning reducing device be compression set accurately and reliably, efficiency is higher, quality is better.Reducing external diameter and angle can regulate arbitrarily, adapt to the cone-shaped nail overcoat spinning reducing of many specifications.And, simple in structure, easy to operate, with low cost.
