Description

Изобретение относитс к испытательной технике, а именно, к ма тниковым копрам дл испытаний изделий на ударные нагрузки.The invention relates to a test apparatus, namely, an assembly copra for testing products for impact loads.

Известен ма тниковый копер дл испытаний образцов на скручивающий удар, содержащий два ма тника с грузами , поочередно взаимодействующие с подвижным захватом образца через двуплечий нагружающий рычаг, неподвижный захват и привод подъема ма тников 1J. .A rotor beam is known for testing specimens for a twisting shock, which contains two masters with weights, which in turn interact with the movable gripper of the specimen through the two shoulders loading lever, the fixed gripper and the lifting gear of the pendulum 1J. .

Наиболее близким к изобретению вл етс ма тниковый копер, содержащий станину, подвешенный к ней ма тник с грузом, взаимодействующий с испытуемым изделием через толкатель, фиксатор ма тника и устройство дл закреплени испытуемрго издели .Устройство дл закреплени испытуемого издели выполнено в виде регулируемого по высоте стола и прижима, а толкатель - в виде рычага, взаимодействующего с элементом сферической формы, установленным на прижиме 2jiThe closest to the invention is an ejector pile containing a frame, a pendulum suspended from it, interacting with the product under test through a pusher, a pendulum lock and a device for fixing the test article. The device for fixing the tested product is in the form of a table height adjustable and a clamp, and a pusher - in the form of a lever interacting with a spherical element mounted on the clamp 2ji

Недостатком известных ма тниковых копров вл етс то, что они не приспособлены дл испытаний механиз мое свободного хода (МСХ), по услови м испытаний которых необходимо нанести скручивающий удар в сторону расклинивани МСХ, а затем мгновенно приложить усилие в сторону его A disadvantage of the known pendulous copra is that they are not adapted for testing the free wheeling mechanism (MA), under the test conditions of which it is necessary to inflict a twisting blow in the direction of wedging the MAA, and then immediately make an effort towards it.

10 заклинивани .10 jamming.

Цель изобретени - расширение функциональных возможнрстей путем проведени испытаний механизмов свободного хода.The purpose of the invention is to expand the functional possibilities by testing the free-wheeling mechanisms.

Claims

This goal is achieved by the fact that in an antenna maker containing a frame, a bearing with a weight suspended from it, interacting with the product under test through a pusher, an attachment lock and a device for sealing the product under test, the pusher is made spring-loaded, the device for fixing the subject from 393 Delhi is made in the form of a clip installed with the possibility of rotation, with the surface of which the pusher interacts, and the pile driver is equipped with a calibrated spring installed parallel to the pusher, one end of which the second is attached to the holder, and the other - on the frame. The drawing schematically depicts the described miniar head in section. A rotary pile-driver contains statiin 1, a tiller 2 suspended with a weight 3, interacting with a spring-loaded pusher C, and the trajectory of the tandem is perpendicular to the plane of the drawing, a device for fixing the test article 5 made as a rotatable holder b, c the surface of which interacts the plunger k and the calibrated spring 7, mounted parallel to the plunger, one end of which is fixed on the holder 6 and the other end on the base 1 using the bolt 8, which also serves to regulate ovki value calibrated tension springs 7 on the frame are also provided two retainer 9 for eliminating repetitive blows pendulum 2 .. Koper operates as follows. The tested article 5 is a free-wheeling mechanism — it is mounted in the holder 6. The bolt 8 of the calibrated spring 7 is extended by a certain force, which presses the holder 6 to the pusher. The load 3 of the tambour 2, the pad from a certain height, interacts with the pusher t, which transmits the impact force to the holder 6, which turns the spring 7. After the end of the impact, the spring-7 instantly affects the holder 6c with the test piece for 5 seconds for4 by the force that determines the magnitude of the loads. In order to avoid a second strike, the symbol 2 stops with one of the fixators. To carry out the next test cycle, the symbol 2 deviates to the other side and, having made a shock, stops with the other lock 9M the keyboard of the described structure allows to expand the field of use of the satellite commands when testing, as it gives the opportunity to conduct testing of the mechanisms of free motion for shock loading,. Claims of the Inventory Copier comprising a frame, a bearing with a weight, which interacts with the test product through a pusher, a lock and a device for fixing the test product, in order to expand its functionality by testing of the freewheel, the plunger is spring-loaded, the device for fixing the tested product is made in the form of a clip installed with the possibility of rotation, with the surface of which interact A pusher is mounted, and the pile driver is equipped with a calibrated spring mounted parallel to the pusher, one end of which is fixed on the holder and the other end on the frame.
