Abstract

The invention relates to metal working. The aim of the invention is the expansion of technological capabilities by providing grinding of incomplete cylindrical predominantly concave surfaces of large-sized parts. The workpiece 17 is mounted on a table 16, having the ability to move in a vertical plane so that the axis of swing of the shaft 3 is the center of a circle of radius R of the work surface 18. The grinding head with a circle 11 through the shaft 3, the rocker arm 5 and the lever 7 perform the swing - telnaya movement at an angle equal to the angle of the incomplete cylindrical surface 18 of the workpiece 17. Circle 11, rotated from the engine 12 by means of a three-step belt drive with pulleys, is supplied by a hydraulic cylinder 9 to the surface to be treated. In this case, the carriage 15 performs reciprocating movements by an amount equal to the length of the workpiece to be machined. 2 Il. SO yu with 4:00 F (/ g.

Description

eleven

The invention relates to metal-working and can be used in grinding incomplete cylindrical, predominantly all-bend surfaces of large-sized parts.

The aim of the invention is the expansion of technological capabilities by providing grinding of incomplete cylindrical surfaces.

Kah FIG. 1 shows the device, front view; in fig. 2 shows section A-A in FIG. one.

The proposed device includes a housing 1 fixed on a bed 2, in which a pulley 4 is mounted with the possibility of swinging at an angle 3. At the output end of the shaft 3 the pulley 4 is mounted for free rotation and the rocker arm 5 is rigidly fixed. Axis 6 is fixed on one arm of the rocker arms 5 , carries a double-shouldered lever 7 and a pulley 8 installed with the possibility of free rotation, and the second shoulder of the rocker arm 5 is pivotally connected to the core

using the hydraulic cylinder 9. On one surface - 25 grinding head, installed 30

A grinding arm 10 with a spindle of circle 11 is fixed to the two shoulders of the lever 7, and the second arm is hingedly connected to the rod of the hydraulic cylinder 9.

The rotation of the grinding wheel 11 is carried out from the electric motor 12 mounted on the housing 1 using a three-stage belt drive through the pulleys 13, 4, B and 14. The carriage 15 with the table 16 is installed on the bed 2 guides and is able to move along them.

The workpiece 17 is mounted on the table 16 in such a way that the axis of swing of the shaft 3 is the center of a circle with a radius R of the work surface 1B.

The proposed device works as follows.

35

Parallel to the axis of rotation of the spindle circle, the swing axis of the two-arm lever, the rotational drive of the circle spindle containing the electric motor, as well as the belt transmission and hydraulic cylinder for moving the head, characterized in that in order to expand the technological capabilities by providing grinding of incomplete cylindrical surfaces, the device is equipped with mounted in the housing with the possibility of swinging the shaft with a rocker attached to it, on one shoulder of which, parallel to the axis of the shaft, the axis of swing of the two-armed lever n, and a second arm pivotally connected to the housing of the hydraulic cylinder, the rod of which is pivotally connected to one arm a two-armed lever.

The grinding head 10 with a circle 11 through the shaft 3, the rocker 5 and the lever 7 makes swinging movements at an angle about equal to the angle of the incomplete cylindrical surface 18 of the workpiece 17. The circle .11, rotated from the engine 12, using a pulley belt with a pulley 13, 4, 8 and 14, is supplied by hydraulic cylinder-9 to the surface to be treated.

At the same time, the carriage 15 reciprocates by an amount equal to the length of the surface 18 to be treated.

F. formula

A device for typing, which contains a double-arm lever placed on the body, on one shoulder of which a grinding head with a spindle of a circle is fixed, and the second shoulder is hingedly connected to a gear

Parallel to the axis of rotation of the spindle circle, the swing axis of the two-arm lever, the rotational drive of the circle spindle containing the electric motor, as well as the belt transmission and the hydraulic cylinder for moving the head, characterized in that, in order to expand the technological capabilities by providing grinding of incomplete cylindrical surfaces in the housing with the possibility of swinging the shaft with a rocker fixed on it, on one shoulder of which, parallel to the axis of the shaft, the axis of swing of the two shoulders is set n, and a second arm pivotally connected to the housing of the hydraulic cylinder, the rod of which is pivotally connected to one arm a two-armed lever.
