Description

one

The invention relates to the field of mechanical engineering and can be widely used in other industries, in particular in instrument engineering and radio engineering, where it is necessary to ensure reliable operative fastening of rotary devices, removable blocks, etc., with simultaneous electrical connection of these mobile devices.

Known clamp on the main ed. St. No. 407095, in which the L-shaped tack is made with internal thread and screwed onto the screw with the possibility of axial stirring, when the screw is rotating, and the nut is mounted on the end of the screw from the side of the tack.

However, the impossibility of visual observation of the position of the nut-sticking reduces the reliability of fastening.

In order to increase the reliability of fixation by providing visual observation of the position of the fixing element of the gripper, the clamp is mounted on the screw and connected to the L-shaped clamping groove sleeve and placed between the housing and the screw head knob with the protrusions located in the sleeve grooves.

FIG. 1 is a perspective view of the clamp in the “fixed” position; in fig. 2- the same, disassembled, axonometrics.

The clamp (see Figs. 1 and 2) includes a housing 1, in which the screw 2 is located with a screwed nut-clamp 4. The latter includes a sleeve 5 with grooves 6 into which the projections 7 are inserted to the outside of the handle 8 and placed between the housing 1 and the head 3 of the screw 2. On the rim of the handle 8, an index-index 9 is installed. The protrusions 7 of the handle 8 are arranged coaxially with the sleeve 5 and inserted into

grooves 6 of the sleeve 5. Between the rim of the handle 8 and the housing 1 is placed the locking ball 10. At the end of the screw 2 inserted into the hole 11 of the handle 8, a ring 12 is fixed. The nut-clamp 4 is provided with a conical lock 13.

The housing 1 has surfaces 14 and 15 to limit the rotation of the nut-sticking 4. On the sleeve 5 and the knob 8 we put the springs 16 and washers 17. To the end of the nut-sticking 4

an insulating block 18 is attached with pin-cutting knives 19 and petals 20, to which the conductors 21 of the wiring diagram of the movable device 22 are attached. The device 22 is attached to the cabinet 23 that houses the insulating block 24 with slots 25. The block 24 has open slots 26.

The clamping operation is carried out as follows.

When screw 2 rotates in arrow A, the nut gripper 4 rotates with it up to the stop into surface 14, and then moves along the axis of the clamp along arrow B, compressing the spring 16 and securing the device 22 in the cabinet 23, at the same time cutting the contact blades 19 in the slots 25. the position of the grip nut 4 corresponds to the position of the indicator 9 of the knob 8 at the “Fixed.

When rotating in the opposite direction, spinning occurs, and the nut-clamp moves along the arrow B up to the stop into the ring 12 and rotates until it comes in contact with the surface 15, simultaneously through the groove 26 withdrawing (turning off) the knives 19 from the slots 25. This position of the nut-sticking corresponds to the position pointer 9 knob 8 at the mark “Cleared-Disabled.

Visual observation of the position of the nut-sticking eliminates possible deviations of the sticking from the normal position, thus ensuring quick and reliable fixing and connecting of movable devices. At the same time, the clamp provides mechanical interlocking of the electrical connection, performing the function of a mechanical interlock disconnector.
