Изобретение относитс к машиностроению и может быть использовано при чистовой обработке винтовых и кольцевых поверхностей, профиль которых образован дугой окружности, например шариковых винтов и подшипниковых колец.The invention relates to mechanical engineering and can be used in the finishing machining of screw and ring surfaces, the profile of which is formed by an arc of a circle, for example ball screws and bearing rings.

Известно устройство дл выглаживани канавок полукруглого профил , содержащее корпус, несущий инструментодержатель , св занный передаточным механизмом с приводом lj.A device for smoothing grooves of a semicircular profile is known, comprising a housing carrying an instrumental holder associated by a gear mechanism with an actuator lj.

Одним из основных недостатков указанного устройства вл етс низка производительность при обработке канавок , профиль которых образован дугой окружности. На оптимальной скорости выглаживани при обработке деталей с канавкой полукруглого профил холостой пробег инструмента без контакта с деталью составл ет половину времени обработки. Холостой пробег инструмента еще более увеличиваетс пои обработке канавок сOne of the main disadvantages of this device is the low productivity in the processing of grooves whose profile is formed by an arc of a circle. At the optimal smoothing speed when machining parts with a groove of a semicircular profile, idle mileage of the tool without contact with the part is half the machining time. The idle mileage of the tool is further increased by grooving

профилем, образованным дугой менее поле-вины окружности, что отрицательно сказываетс на производительности обработки.the profile formed by the arc is less than the margin of the circle, which adversely affects the processing performance.

.Цель изобретени - повышение производительности выглаживани .The purpose of the invention is to improve the performance of smoothing.

Цель достигаетс тем, что устройство снабжено регулировочным винтом и подпружиненными башмаками, установленными на направл ющих, выполненных The goal is achieved by the fact that the device is equipped with an adjusting screw and spring-loaded shoes mounted on guides made

to в корпусе и соединенных между собой введенным в устройство валом, на котором размещен привод, при этом из башмаков установлен с возможностью контакта с регулировочным вин15 том, а передаточный механизм снабжен рычагом с кареткой, имеющей паз и установленной с возможностью взаимодействи с введенным в устройство ку лачком, закрепленным на валу, прохого д щим сквозь паз.to in the housing and interconnected by the shaft inserted into the device, on which the drive is placed, while of the shoes is installed with the possibility of contact with the adjusting screw 15, and the transmission mechanism is equipped with a lever with a carriage having a groove and installed with the possibility of interaction with the input screw a piece attached to a shaft that passes through the groove.

Claims

The drawing shows a diagram of the device. The device comprises a housing 1 with translational guides, on which the shoes 2 are installed, in contact with the springs 3. An adjusting screw i serves to move the shoes 2 together with an actuator 5 attached to them. On the output shaft 6 of the actuator 5, a cam 7 is mounted. On the case 1, a transmission mechanism 8 is also fixed, on one output shaft of which a tool holder 9 is mounted and on the other - a lever 10 with a slider carrying a carriage 11 with a groove through which the shaft 6 passes. contact with the cam 7. The profile of the cam 7 is chosen in such a way as to ensure uniform movement of the tool in the working section of the profile and a smooth change in its speed in the areas of the reverse, rigid closure of the elements in contact with the cam the carriage and the maximum swing angle in the absence of distortion of the law of motion of the tool. The device operates as follows. The required swing angle is set, for which, by rotating the adjusting screw 4, the output shaft 6 pressed by the elastic element 3 with the cam 7 is moved along the body guide 1. The guide carriages 11 move along the swinging arm 10, Drive 5 rotate the cam 7, which moves the carriage 9 14 ku 11 relative to the support of the output shaft 6; The carriage 11 rotates the lever 10, which through the transmission mechanism 8 communicates the movement to the tool holder 9 with the tool. The use of the device makes it possible to increase the machining productivity by more than 2 times, increase tool life by 25-30 and improve the quality of the surface layer of the part. Claims I A device for smoothing out the grooves of a semicircular profile, comprising a housing carrying an instrumental carrier associated with a transmission mechanism with a drive, which means that, in order to improve the performance of smoothing, the device is equipped with an adjusting screw, spring-loaded shoes mounted on guides made in the housing and connected between themselves by a shaft connected to the device connected to a drive, a slider carrying a carriage with a groove and a cam, while one of the shoes is mounted flax with the possibility of contact with the adjusting screw, and the cam is located on the shaft passing through the slot of the carriage.
