(54.) DEVICE FOR THE IMPLEMENTATION OF KETTING

one

This invention relates to a weight measuring technique.

According to the main author. St. No. 588473 a device for imposing weights is known, comprising a frame, a weight holder with a set of weights and a loading mechanism with a rod. In the device, the gyreder holder is made in the form of successively connected and connected movably relative to each other along the vertical axis and connected to the loading mechanism of the detachable links of known mass, each of which contains a hollow cylinder with a conical hole in the bottom 1.

However, when removing weights from the prism of a balance or a calibrated instrument to ensure guaranteed pressing of the links of the grip holder to each other and to the tapered hole of the upper base of the loading mechanism, the piston of the rod in its extreme upper position does not reach the stop in the ram. The axial force from the pressure beneath the piston closes through the links of the giraeder to the upper base. In case of exceeding the permissible value for this material of the links of the giperderzhitel, for example, when leaving the pressure reducer, the links of the hyderderm are disturbed, resulting in distortion of the geometrical dimensions of the links, jamming, etc., which leads to weights The ability to see the links of the hyperer is increased in the range of small weights when the links of the gyreder are satisfied with a minimum weight. In this case, the links are made of thin-walled and made of a material with a minimum specific gravity, for example, from aluminum alloys, which have lower strength characteristics compared to steel.

The purpose of the invention is to increase the reliability of the device by eliminating see

J5 links giraderzhatel.

The goal is achieved by the fact that in it the loading mechanism rod is provided with a rod mounted coaxially with it, on which is placed a sleeve, which interacts with its upper surface with the surface of the lower link of the hyperer, and with an elastic element located between the end of the rod and the sleeve, and the upper part of the rod is made emphasis for the sleeve.

The drawing shows the proposed device, the overall appearance.

The device for overlaying weights contains an upper base 1, a lower base 2, a gidrederzhatel 3, a hydraulic loading mechanism mounted on the lower base 2 and consisting of a power cylinder 4, inside which the compacted brush 5 is fitted, with a lever 6 interacting with a displacement sensor 7 ,, and coaxial rod 8 with an emphasis 9 in the upper part, for example in the form of a collar. A hub 10 is mounted on the rod 8, the upper surface of which interacts with the mating surface of the lower link of the bearer 3. An elastic element, such as a spring 11, is installed between the end of the rod 5 and the sleeve 10 and is centered relative to the rod 5 by the clip 12. The upper link of the rod 4 has a link 13 interacting with the imposition of goods with a prism 14 of the loaded device (not shown), the vertex of which is exposed along the axis of the gyroholder 3. On each link of the gyroderm 3 impose interchangeable ring or C-shaped weights 15 known mass. The stop 9 limits the movement of the sleeve 10 up under the action of the spring 11. By varying the height of the rod 8, the force of preloading the spring 11 is controlled and at the same time the gap between the mating surfaces of the sleeve 10 and the lower link of the bearing support 3 at the extreme lower position of the rod. The washer 12 is used simultaneously to lock the rod 8.

The device for imposing weights works as follows.

Under the action of force on the piston 16 of the shaft 5, for example, from the hydraulic pressure supplied to the loading mechanism clamp 17, the pinch 16 of the rod 5 in the extreme upper position abuts against the end of the power cylinder 4, which senses the fully named force. In this position, the stem 5 of the linkage 13 of the upper link of the bearing support 3 is disengaged from the prism 14, the links of the support link 3 are pressed by the sleeve 10 to each other and the tapered hole of the upper base along the mating surface by the force of the spring 11, the sleeve 10 is pressed by the support rod 3 from the stop 9 by certain clearance. When pressure is applied, for example, hydraulic, to the clamper 18 of the loading mechanism (the cavity under the piston is drained through the clamper 17), the rod 5 with the rod 8 starts to move downwards. The gap between the stop 9 and the sleeve 10 is reduced. The spring 11 presses the sleeve 10 and the links of the giperderder to each other and to the tapered hole of the upper base to

pressing the sleeve 10 into the support 9, after which the sleeve 10 with the gi-retainer starts to move downwards together with the rod 5 of the loading mechanism. Top link girederzha. tel engages with a prism 14,

it is also stopped by its mass (with or without weights) loading the prism. The movement of the slider is detected by the sensor 7, which outputs a signal proportional to the magnitude of the movement. When the loading mechanism's slide 5 moves down, the next link engages with the upper link and adds its weight (with or without 15 weights) to the weight of the upper link, etc. When the loading mechanism of the loading mechanism 5 reaches its lowest position, The lower link surfaces of the giver holder 3 and the bushings 10 form a gap, for example 5 + 7 mm, the giraderder 3 with the weight of its links (with or without 15 weights) loads the prism 14. After loading the prism 14 with the weight of each link, the readings of the calibrated instrument are recorded. (not showing n) for example a force sensor. The unloading of the prism 14 occurs in reverse order, when fluid pressure is applied to the clamper 17 of the loading mechanism (through the clamper 17, the cavity is drained above the rim 16), and the clamps 5 with the hub 10 begin to move upwards. The lower link rests on the mating surface of the sleeve 10 and is disengaged from the previous link of the gyroholder 3, unloading the prism 14, etc. to the upper link. After the upper link reaches the stop at the upper base 1, the rod 8 with the rod 5 continues to move upward until the piston 16 of the rod 15 stops at the end of the power cylinder 4, while the force from the hydraulic pressure under force 16 closes on the power cylinder 4, spring 11 squeezes and, with its force, presses the sleeve 10 and the hub holder link to the upper base

by mating surfaces.

The use of the proposed device for imposing weights makes it possible to increase its reliability by eliminating the seeming of the parts of the bearer by the force of the hydraulic pressure under the mechanism.
