Technical Field
The utility model relates to the technical field of machining, specifically be brush roller shell and rubber roll cover surface grinding or coping's auxiliary fixtures device.
Background
The sleeve type part is a part with a hole in the middle, and is generally applied to the mechanical industry. However, the sleeve part needs to be ground on a common cylindrical grinding machine, so that the clamping of the sleeve part is an essential link for grinding, and the grinding of the grinding machine usually adopts a three-melon chuck to clamp a workpiece or adopts two centers to tension the workpiece by means of a tensioning center sleeve at present. Although the clamping mode can fix the workpiece, the clamping is inconvenient, the machining efficiency is low, and the workpiece is easy to deform in the machining process, so that the product percent of pass is reduced, and the smooth machining is difficult to ensure.
In particular, in a copper and copper alloy strip production line, after a rubber roller sleeve and a brush roller sleeve used in the production line are used for a period of time, the surface of the roller sleeve in contact with the strip is uneven, low in the middle and high on two sides, and the surface quality of the strip is adversely affected, so that the surface of the roller sleeve used for a period of time needs to be polished and leveled.
Disclosure of Invention
The utility model discloses a solve present rubber roll cover and brush roll cover the surface unevenness back of appearing, lack the technical problem that can the centre gripping and assist the device that revises, provide an auxiliary device of cover type part excircle grinding.
The utility model discloses an adopt following technical scheme to realize: an auxiliary device for cylindrical grinding of sleeve parts comprises a mandrel, wherein a frustum is fixedly sleeved at one end of the mandrel, a taper sleeve is movably sleeved at the other end of the mandrel, at least one adjusting spacer sleeve is further sleeved on the outer side of the taper sleeve, external threads are formed in the other end of the mandrel, and a locking nut is screwed on the external threads; the frustum surface of the frustum is opposite to the frustum surface of the taper sleeve; and (4) processing tip holes on two end surfaces of the mandrel.
The utility model is designed for grinding the surfaces of the roller sleeve and the rubber roller sleeve. The adjustable taper sleeve is composed of a mandrel with a frustum, a movable taper sleeve, an adjusting spacer bush and double locking nuts. The brush roller sleeve and the rubber roller sleeve which need to be polished are firstly sleeved on the mandrel, the taper sleeve is arranged on the top, then the adjusting spacer sleeve is arranged, the number of the mounting spacer sleeve is selected or rejected according to the length of a workpiece, finally, the double nuts are used for locking, the frustum and the taper sleeve on the mandrel have the automatic adjusting and centering function when the mandrel and the taper sleeve are clamped, the number of the adjusting spacer sleeve can meet the grinding requirements of the roller sleeves with different lengths, and then the tool can grind on an external grinding machine after a drive plate is arranged, and the tool can meet the external grinding requirements of the roller sleeves with certain external diameters and lengths.
The utility model discloses simple structure, convenient to use, the practicality can extensively be applicable to grinding cover class part on ordinary cylindrical grinder.

Detailed Description
An auxiliary device for cylindrical grinding of sleeve parts comprises a mandrel 1, wherein one end of the mandrel 1 is fixedly sleeved with a frustum 5, the mandrel 1 is movably sleeved with a taper sleeve 2 from the other end, the outer side of the taper sleeve 2 is also at least sleeved with an adjusting spacer 3, the other end of the mandrel 1 is provided with an external thread, and a locking nut 4 is screwed on the external thread; the cone table surface of the cone table 5 is opposite to the cone table surface of the cone sleeve 2; and (4) processing tip holes 6 on two end surfaces of the mandrel 1.
The lock nuts 4 are a pair.
The inner hole of the taper sleeve 2 is in transition fit with the mandrel 1; the inner hole of the adjusting spacer bush 3 is in clearance fit with the mandrel 1.
FIG. 1 shows a mandrel with a frustum, wherein two end faces of the mandrel are provided with tip holes, one end face of the mandrel is provided with two threaded holes for fixing a driving plate, the whole mandrel requires good concentricity and cylindricity, the frustum is welded at one end of the mandrel, the frustum is required to be perpendicular to the mandrel, and the other end of the mandrel is provided with an external thread with a certain length.
Fig. 2 is a diagram of a taper sleeve, which is composed of a frustum and a shaft sleeve, and an inner hole of the taper sleeve is in transition fit with a mandrel.
Fig. 3 shows an adjusting spacer bush, the inner hole of which is in clearance fit with the mandrel.
