SU130368A1 - Clamp for fastening cylindrical parts - Google Patents

Description

Known grippers for fastening cylindrical parts, made in the form of a yoke consisting of two half sleeves, rotatably worn at one end on two axes, mounted on a common bracket, and pulled using a hook, worn on the handle axis, mounted on the free end of one the half-clamp is eccentric relative to the axis of its rotation, and interacting with the neck of the pin mounted on the free end of the second half-clamp. However, in such grippers it is impossible to adjust the tension of the clamp.

In the described grip, this drawback is eliminated by the fact that the pin is mounted pivotally on two axles located eccentrically relative to its neck, and is equipped with a device that prevents it from spontaneously turning and made in the form of a multifaceted head, rigidly fastened to the neck of the pin and interacting with the stopper on the half-hitch . To fix the semi-bolts in the open position, a through-axis is mounted in the bracket, rotated by a handle with a stopper and equipped with two levers attached to it, interacting with the respective semi-bolts.

FIG. 1 shows the capture; in fig. 2 is a section along AA in FIG. one; in fig. 3 is a section through BB in FIG. 2; in fig. 4 - part of the locking device.

The grip for fastening the cylindrical parts consists of a bracket /, two half-sleeves 2, a device 5 for closing the grip and a locking device 4 for fixing the half-sleeves 2 in the opened position. In bracket 1, axles 5 are fixed, on which half-sleeves 2, which are fitted with rubber pads 6, are rotatably mounted with their ends.

Co. 130368-2. The device 3 for closing the grip consists of a handle 7 mounted on axles 5 mounted on the free end of one of the floor. Clamps 2, hook 9 mounted on axle 10 fixed in the handle 7, and pin // mounted on the free The end of the other half-clamp 2. To create the possibility of adjusting the tension of the clamp, the pin 11 has two pins 12, which are located eccentrically relative to the neck 13, with which the hook 9 engages. From spontaneous rotation the pin 11 is protected by a multi-faceted head 14, which with its two faces 15 interacts It is located at the edges of stopper 16 located on the half-wheel 2.

The device 4 for locking the gripper in the open position consists of two levers 11, worn on the axis 18 and wedging the side planes of the half sleeves 2, and a handle 19 with a stopper 20 serving to rotate the axis 18 with the levers 11.
