Abstract

The utility model discloses a flat head sleeve for a roll lathe, which comprises a cylindrical body; the outer wall of the rear section of the cylinder body is provided with a clamping platform which is matched with the clamping claw of a lathe; a through hole which is matched with a roller head on a transmission end of a roller is axially arranged in the cylinder body; and the front section of the through hole is a clamping hole which comprises two planes and two outer convex arc-shaped surfaces which are alternatively connected. The flat head sleeve for the roll lathe has simple structure, is convenient to use, can improve the stability of the roller lathe in a roller process so as to improve the roller processing precision.

Description

Roll lathe homalocephalus cover

Technical field

The utility model relates to the Roller Machining technical field, refers to a kind of roll lathe homalocephalus cover particularly.

Background technology

Roll lathe is the visual plant of processing large-tonnage roll.Existing roll lathe is to clamp roll driving end homalocephalus by the lathe claw when processing roll.Yet in the roll pass process, this clamping mode is easy to cause roll loosening, makes that the precision of Roller Machining is not high, and is easy to generate useless groove.Therefore, need badly a kind of improved roll lathe with the homalocephalus cover to overcome aforementioned disadvantages.

Summary of the invention

The purpose of this utility model is exactly that a kind of roll lathe simple in structure, easy to use homalocephalus cover will be provided, and uses it can improve the stability of roll lathe in the processing roll process, thereby improves the precision of Roller Machining.

For achieving the above object, the designed roll lathe of the utility model comprises columnar body with the homalocephalus cover, described columnar body one end the back segment outer wall be formed with and be used for the chucking platform that matches with the lathe claw, axially offer in the described columnar body and be used for the through hole that matches with roll driving end roller head, the holes for clamping of the leading portion of described through hole for alternately being formed by connecting by two planes and two outer convex globoidals.

Advantage of the present utility model is: the ccontaining roll driving end of the through hole roller head that designed roll lathe overlaps with homalocephalus, the outer contour shape of the shape of its holes for clamping and roll driving end homalocephalus is complementary, thereby can carry-over moment, the claw of roll lathe clamps by the clamping platform on its outer wall, makes roll lathe that stability preferably be arranged when processing roll.In addition, increase this roll lathe homalocephalus cover, need not destroy the original structure of roll lathe, economical and effective, and this homalocephalus cover can reuse, and can save spare parts consumption.

Preferably, the sidewall of the columnar body at described holes for clamping place is provided with the screw of perforation, and the axis normal of described screw is in the axis of described columnar body.Bolt passes screw and overlaps interior roll driving end roller head with further fixing described roll lathe with homalocephalus.

Preferably, the axis normal of described screw is in described two planes, and bolt contacts with the plane of roll driving end roller head, thereby can further be fixed.

Preferably, the back segment shaft section area of described through hole is greater than the shaft section area of described holes for clamping, thereby can alleviate the weight of described roll lathe with the homalocephalus cover, is convenient to operation.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is described in further detail.For embodiment of the present utility model being described better, the structure of first simple declaration roll driving end roller head.As depicted in figs. 1 and 2, roll driving end roller head 5 has a homalocephalus running part, and this homalocephalus running part has two arcwall 5a and two planar wall 5b, in the Roller Machining process, promptly by this homalocephalus running part carry-over moment.

Shown in Fig. 3～4, the roll lathe of present embodiment comprises columnar body 1 with the homalocephalus cover, the back segment outer wall of described columnar body 1 is formed with chucking platform 2, axially offer through hole 3 in the described columnar body 1, the holes for clamping of the leading portion of described through hole 3 for alternately being formed by connecting by two plane 3a and two outer convex globoidal 3b.Described columnar body 1 can be for cylindrical, but not as limit, can be for the column arbitrarily that is fit to make, as polygon cylinder, elliptic cylindrical etc.In conjunction with Fig. 5 as can be seen, described chucking platform 2 is used for matching with the claw 6 of roll lathe, and described through hole 3 matches with described roll driving end roller head 5, and the outer profile size at the homalocephalus transmission position of the size of its holes for clamping and described roll driving end roller head 5 is complementary.

Further, the sidewall of the columnar body 1 at described holes for clamping place is provided with the screw 4 of perforation, and the axis normal of described screw 4 can further be fixed described roll driving end roller head 5 by bolt (figure does not show) like this in the axis of described columnar body 1.Further, the axis normal of described screw 4 that is to say that in described two plane 3a the axis normal of described screw 4 is in the planar wall 5b at the homalocephalus transmission position of described roll driving end roller head 5, bolt and planar wall 5b offset, and can fix described roll driving end roller head 5 better.

The back segment shaft section area of described through hole 3 is greater than the shaft section area of described holes for clamping, if the intensity that can satisfy the demand, thus can alleviate the weight of described roll lathe with the homalocephalus cover, be convenient to operation.In the present embodiment, the part of this through hole 3 except that described holes for clamping is and coaxial cylindrical of described columnar body 1.

Introduce the using method of the special-purpose homalocephalus cover of roll of the present utility model below with reference to Fig. 5.At first, the special-purpose homalocephalus cover of described roll is enclosed within on the roll driving end roller head 5, uses bolting,, thereby be fixed on the roll lathe chuck 7 then by the chucking platform 2 on the described columnar body 1 of roll lathe claw 6 chuckings.The thimble at described roll lathe chuck 7 middle parts (figure does not show) stretches out, withstand the outermost end of roll driving end roller head 5, with further with stationary roll, like this, make roll lathe that stability preferably be arranged when processing roll, the probability that produces useless groove in the roll pass process has been reduced by 10%, thereby can effectively improve the machining accuracy of roll and the quality of product.
