Description

In the proposed adaptation to a shelling machine, to stop the gearbox when approaching the supor to the spindles, a bar is used, located in the guide beds and provided with a stop bolt against which the finger of the carriage of the carriage rests in order to move the bar through the system of levers on the gearbox shift lever.

In FIG. Figure 1 shows a side view of the fixture and caliper in which it is attached; FIG. 2 - the same in cross section.

To one of the sliders of the supreme shearing machine, at which the proposed device is applied, a finger (which enters into a long notch of the bar 2 fixed in the machine guides of the machine) is screwed. At one end of the strap 2, facing the spring, there is a stop bolt 5, and at the other end there is a fist. The long notch of the bar 2 allows the finger 7 to move freely between the bolt J and the cam 4, while the caliper is moving, without hitting the bar 2. The bar 2 is protected from accidental movements by a spring placed in the cap 5 and pressing the bar through the friction mat gasket (247 )

rial To prevent the bar 2 from lifting upwards, brackets 5 and 7 are used.

A roller 5 passes through the side walls of the box of speeds over the bar 2. The lever P at one end and the handle / 2 at the other end (Fig. 2). Inside the speeding box on the roller 8, a lever 10 is mounted, supported by a spring 13 so that the lever 9 at this time presses the bar 2, which is not in contact with the notch lever P.

The speed box is turned off by moving the halves 14 of the clutch with the lever 11 rotating on the axis 75 and having the handle extended to the outside. The cam clutch 14 is held in the on position by the bolt 16, screwed into the lower end of the lever 77 and resting against the end of the internal lever 10 and a spring is placed between its halves (not shown in the drawing), which tends to turn off the clutch.

When the clutch 14 is turned on, the lever 77 presses a button that turns off both the forward and reverse travels of the accelerated supor feed motor, which rotates the connecting roller 77, transmitting the gears to simultaneously rotate both of the spindle sliders with the help of a gear wheel. When the clutch 14 is turned off, the lever 7 / automatically, under the action of the spring, goes to the left (according to the drawing of FIG. 2) and, by releasing the start button, enables the retraction button of the motor to accelerate the feeding of the supor, so that the suport at this moment, corresponding to the end of the turning of the block, returns to the starting position.

The operation of the device is carried out in the following order. When the supor knife approaches a distance close to the center of the spindles, finger /, press on the bolt 3, moves the bar until the fist 4 starts to lift the end of the lever 9, while turning the roller 8. While rotating the roller 8, the end of the internal lever JO lowers and releases the bolt 16 of the lever 7 /, which under

spring action turns off the cam gearbox clutch.

In order to randomly turn off the gearbox in the course of the machine, there is a handle 12 that turns the roller 8 in order to release the bolt 16 of the lever 77.

The subject matter of the invention.

Adjusting to a shelling machine to turn off the gearbox when the suporport approaches the spindles, characterized by using a guide bar 2 with a stop bolt 3 in the guide frame to act on it with a karak finger and a cam 4 acting by means of the levers 9, 10 on the gearbox transfer lever 77 .
