Description

The invention relates to hand-held devices for assembling-disassembling components, in particular for mounting-dismounting calibrating or profiling rollers, which can be mounted on parallel shafts with axial threaded holes.

The peculiarity of mounting-dismounting calibrating or profiling rollers is that the profile of one roller enters the counterpart of the profile of another roller, therefore their installation-disassembly is possible only together.

The purpose of the invention is to increase productivity and expand the technological capabilities of the device.

FIG. 1 shows the device, the cut; figure 2 - section aa in figure 1; fig. 3 - working in a pair of devices, a general view.

The device consists of a guide cylinder 1 located inside the thrust cup 2, coaxial to them with the mounting screw 3 with the shank, the spindle nut 4 and the handle 5.

The device is provided with a lead screw rigidly connected to the handle 5 at one end with a running screw 6 mounted rotatably relative to the longitudinal axis on the shank of the mounting screw 3, a pressure ring 7 having radial pins 8 located on the running nut 4 interacting with the ends of the pressure ring 7 cup springs 9.

The pressure ring 7 and cup springs 9 are mounted on the suspension nut 4 with intermediate washers 10 and Nuts 11.

The guide cylinder 1 has a guide pin 12 at one end and a central hole through which the threaded end of the mounting screw 3 passes, which has a turnkey 13 at the end of the shank, and at the other end the guide cylinder 1 has a cover 14, in the central hole of which the lead screw 6 can rotate freely; moreover, the longitudinal grooves 15 are made under the studs 8 on the lateral surface of the guide cylinder 1.

An annular groove 16 is made on the inner cylindrical surface of the thrust cup 2 to accommodate the free ends of the pins 8, and on the outer surface the thrust cup 2 has lugs in which the hinges 17 are hinged.

The device works as follows.

For mounting two rollers 18 simultaneously on parallel shafts 19, two identical devices are used (Fig. 3). The roller 18 is mounted on the guide cylinder 1 of the device, using the mounting screw 3, the device is fixed together with the roller 18 to the end of the shaft 19.

In this case, the key 12 enters the keyway of the shaft 19. Similarly, a second same device is mounted on the other shaft 19, and the profile of one roller 18 enters the counterpart of the profile of another roller 18.

By alternately rotating the knobs 5 of this and other devices, the rollers 18 are mounted on the shafts 19. In this case, the rollers 18 are guided along the shafts by 19 shanks 12.

When the lead screw 6 rotates, the nut 4 moves along the screw 6 and moves the pressure ring 7 (in Fig.1 to the right), which with the pins 8 moves the stop cup 2 also to the right, and the latter pushes the roller 18 onto the shaft 19 with its end face.

When the rollers 18 run without jamming, the springs 9 are not deformed and transmit force from the nut 4 to the pressure ring 7. In the event of a roller skew

0 18 its movement along the shaft 19 and the anvil 2 relative to the guide cylinder 1 is stopped, and with further rotation of the screw 5, the nut 4 begins to move relative to the ring 7, compressing the disk spring 9 (left in Fig. 1).

5 This moment is determined by the increasing force on the handle 5 and the stop of the movement of the roller 18 on the shaft 19.

Since both rollers 18 interact with each other by profiling surfaces, rotating the handle 5 of another device, the second roller 18 starts moving and eliminates the skew of the first roller 18. At this time, the spring 9 of the first device is compressed, straightening, moves the pressure ring 7, which pins 8 moves the stop cup 2 and the roller 18, due to which both rollers 18 move synchronously along the shafts 19. Thus, alternately rotating the handle 5, continue mounting until it is completely finished.

The dismantling process is similar to the installation. In this case, the clamps 17 are hooked onto the rollers 18, the handle 5 is rotated in the other direction, the nut 4 is moved along the screw 6 to the left, and the pressure ring 7 with its pins 8 moves the stop

cup 2 to the left, and grippers 17 are stacked with roller 18 from shaft 19.

In the case of skewing and sticking of the roller 18, the spring 9 is compressed (right in FIG. 1), and then the process is similar to the installation process. The rollers 18 are removed along with the attachments.

When using a device for mounting and dismounting a roller with a single shaft, it works in the same way, while in case of jamming of the mounted part, the alignment is tapped on the mounted part.
