Description

Изобретение относитс к ленточному шлифованию и может найти применение при шлифовании стальных, алюминиевых и графитных стержней.The invention relates to belt grinding and can be used for grinding steel, aluminum and graphite rods.

Известно устройство дл шлифовани цилиндрических стержней, выполненное в виде ленты и привода перемещени обрабатываемого издели , которое установлено на 6a3OBoJ приспособлении , имеющем горизонтальную базовую поверхность ij .A device for grinding cylindrical rods, made in the form of a tape and driving a movement of a workpiece, is installed on a 6a3OBoJ device with a horizontal base surface ij.

Недостатком известного приспособлени вл етс неравномерный износ ленты вследствие врезани абрайивного элемента в обрабатываемый стержень, A disadvantage of the prior art is the uneven wear of the belt due to the embedding of the abrasive element in the rod being machined,

Цель изобретени - обеспечение , равномерного износа ленты и упрощение привода перемещени .The purpose of the invention is to ensure uniform tape wear and to simplify the drive movement.

Дл этого в предлагаемом устройстве базовое приспособление расположено под углом к вектору перемещени ленты, а его базова поверхност выполнена в виде трех участков, при этом образующие первого и третьего участков параллельны одна другой, а угол наклона промежуточного второго участка определ етс из услови сн ти припуска.To do this, in the proposed device, the base fixture is located at an angle to the belt displacement vector, and its base surface is made in three sections, while forming the first and third sections are parallel to each other, and the angle of inclination of the intermediate second section is determined from the condition of removal of the allowance.

На фиг. 1 приведено устройство, продольный разрез; на фиг.2 - то же, вид сверху; на фиг. 3 - ступенчатый паз нижнего элемента и стержень в процессе обработки.FIG. 1 shows a device, a longitudinal section; figure 2 is the same, top view; in fig. 3 - step groove of the lower element and the rod during processing.

Claims

The device comprises a base 1, provided with a vertical axis 2 and an angular slot 3, On the axis 2 with one end rotatably mounted a basic device 4, made in the form of an elongated prism, the other end of which has a threaded rod 5, passing through a slot 3 equipped with a nut. lamb 6 fixing various positions of the element. On the base 1, the supports 7 are mounted, on which the pulleys 8 are mounted, covering the endless abrasive belt 9, which is the top element. The lower branch of the belt is clamped to the prism with a roller 10. To install the processing rods, the prism has a longitudinal groove 11, made in the form of a vertical stupa, consisting of three straight line segments — I, II, and 111, the first and third of which are spaced apart. processing allowances are parallel to each other and tilted at an angle oJ to the working surface of the abrasive belt, and the second segment connecting them is tilted to the surface of the specified belt on the goal 2 of the op amp, the rod is installed on the first step of the groove of the prism 4, and since the first Upenu in a vertical plane inclined at an angle to the work surface s of the belt 9, and the axis of the rod is set under the same angle. This makes it possible to consistently across the entire width of the belt 9 to remove the allowance for processing. The abrasive belt 9 is set in motion and under & along the groove 11 the rod 12 before interacting with the abrasive belt that grips the rod, makes its rotation and translational movement along the groove 11. In the process of processing, when part of the length of the rod is already processed, part of is in processing, some of it is not processed, the surface of the entire rod consists of three surfaces, the first and third of which form coaxial cylinders located outside the belt (outside the processing zone), the difference in the length of radius is equal to The second side, which is under the abrasive belt (in the working zone), is transitional from one cylindrical surface to another, forming a truncated cone with an angle of taper 2 degrees; the second step of the groove, which is About the RF of this conical surface, the same is inclined at an angle of 2 cL to the working surface of the abrasive belt forming this surface. At the exit from the treatment zone, a cylindrical rod, whose axis is inclined at an angle cxi to the working surface of the belt, requires a support surface that has the same inclination as the axis of the rod. This bearing surface is the third step of the groove, when the entire rod leaves the machining zone, it is completely in the third step of the groove. The invention of the device for grinding shch-shindricheskimi rods, made in the form of a tape and drive movement of the workpiece, which is installed on the base device, which is designed to ensure uniform wear of the tape and simplify the drive the movement of the product, the basic device is at an angle to the vector of movement of the tape, and its base surface is made in the form of three sections, while forming the first and third sections are parallel to each other, and the angle of inclination is the exact second section is determined from the condition of the removal allowance.
