Description

Известны загрузочные приспособлени  к бесцентрово-шлнфов льному станку, состо щие из двух параллельных валков, набранных из роликов , 0:си которых наклонены к общей оси валка в разные стороны.There are known loading devices for a centerless locking machine consisting of two parallel rolls, made up of rollers, 0: which are inclined to the common axis of the roll in different directions.

При цилиндрических роликах, как это имеет место на практике, лини ми контактов  вл ютс  дуги эллипсов, a следовательно, заготовка в общем случае контактирует с роликами в одной точке, что позвол ет ей колебатьс  в поперечном направлении: вследствие непрерывности и плотности потока заготовок эти колебани  передаютс  заготовкам, наход щимс  в зоне щлифовани , что преп тствует работе с высокой точностью. Указанный недостаток устран етс  тем, что ролики выполн ют в форме однополостного гиперболоида вращени , имеющего, как известно, пр молинейную образующую, наклоненную к его оси; в этом случае лини  контакта представл ет собой пр мую линию, обеспечивающую с пр молинейной образующей цилиндрической заготовки непрерывный контакт .With cylindrical rollers, as is the case in practice, the contact lines are arcs of ellipses, and therefore, the workpiece generally contacts the rollers at one point, which allows it to oscillate in the transverse direction: due to the continuity and density of the workpiece flux transferred to workpieces in the grinding area, which prevents work with high accuracy. This disadvantage is eliminated by the fact that the rollers are made in the form of a single-cavity hyperboloid of rotation, which, as is well known, has a rectilinear generatrix inclined to its axis; in this case, the contact line is a straight line providing continuous contact with the straight line forming the cylindrical billet.

На фиг. 1 схематически показан валок предлагаемого приспособлени ; на фиг. 2 - разрез вала по АА на фиг. 1; на фиг. 3 дан валок с повернутыми роликами.FIG. Figure 1 shows schematically the swath of the proposed device; in fig. 2 is a section through the shaft according to AA in FIG. one; in fig. 3 Dan roll with rotated rollers.

Рабочими (подающими) органа.ми приспособлени   вл ютс  ролики , выполненные по форме однополостного гиперболоида вращени ; они устанавливаютс  под некоторым углом а к оси заготовки, причем ролики смещены друг относительно друга.The working (feeding) organs of the device are the rollers, made in the form of a single-cavity hyperboloid of rotation; they are set at a certain angle a to the axis of the workpiece, with the rollers being offset from each other.

Как видно из фиг. I, точки 1, 2, 3, 4 пересечени  смещенных торцов всех роликов лежат на одной пр мой АА- Эта пр ма  и используетс  как лини  контакта с заготовками. Дл  получени  необходимого угла контакта ф с заготовкой (во избежание заклинивани  заготовки между роликами ) систему роликов можно повернуть вокруг оси О-О (см. на фиг. 3).As can be seen from FIG. I, the points 1, 2, 3, 4 of the intersection of the offset ends of all the rollers lie on the same straight line AA. This line is used as a line of contact with the workpieces. To obtain the required angle of contact f with the workpiece (to avoid jamming of the workpiece between the rollers), the system of rollers can be rotated around the O-O axis (see Fig. 3).

Один из роликов приводитс  во вращение вокруг его геометрической оси. Заготовка фрикционным путе.м получает вращение и перемещениеOne of the rollers is driven to rotate around its geometric axis. The workpiece friction path. M gets the rotation and displacement
