Description

Изобретение относитс к области клепки, в частности, к ручным инстру ментам дл клепки.The invention relates to the field of riveting, in particular, to hand tools for riveting.

Известен клепальный молоток, содержащий размещенный в корпусе ствол с расположенным в нем с возможностью возвратно-поступательного перемодени ступенчатым ударным бойком, а также спусковой механизм, смонтированный в корпусе.Known riveting hammer containing placed in the body of the barrel located in it with the possibility of reciprocating re-modeled stepped percussion striker, as well as the trigger mechanism, mounted in the housing.

Однако известный клепальный молоток не обеспечивает центрирова1ше по оси заклепки при расклепывании.However, the known riveting hammer does not provide a centering point along the rivet axis during riveting.

Цель изобретени - повышение качества клепки.The purpose of the invention is to improve the quality of riveting.

Предлагаемый молоток отличаетс от известного тем, что он снабжен механизмом центрировани его по оси заклепки, установленным на свободном конце ствола, и подпружиненными штыр ми дл фиксации бойка в исходном положении, установленньти в отверсти х , предусмотренных в стволе, и вхоДЯПР1МИ в кольцевую канавку, выполненичто на бойке; а также установленным между стволом и корпусом молотка амортизатора.The proposed hammer differs from the known one in that it is provided with a rivet axis centering mechanism mounted on the free end of the barrel and spring-loaded pins for fixing the striker in the initial position, installed in the holes provided in the barrel, and into the annular groove, on peen; as well as installed between the barrel and the shock absorber hammer housing.

Механизм центрировани выполнен в виде втулки, сид щей на конце ствола охватывакицей ее обоймы, установленной с возможностью относительного поворота; и поворотных двуплечих рычагов, воздейств тощих на заготовку , закрегшен1шх на равном рассто нии один от другого во втулке и про ход щих каждый концом через радиальные пазы, выполненные во втулке и в обойме.The centering mechanism is made in the form of a sleeve, which, at the end of the barrel, surrounds its casing, which is installed with the possibility of relative rotation; and two-arm swivel arms, which lean on the workpiece, fasten at equal distance from each other in the sleeve and pass each end through radial grooves made in the sleeve and in the cage.

На фиг. 1 показан клепальный молоток , общий вид; на фиг. 2 - разрез по А-А фиг. 1 ; на фиг. 3 - обгций вид центрирующего механизма; на фиг. 4 положение рычагов центрирующего механизма в исходном положении; на фиг. 5 - то же, в рабочем положении.FIG. 1 shows a riveting hammer, a general view; in fig. 2 is a section along A-A of FIG. one ; in fig. 3 - obgciya view centering mechanism; in fig. 4 position of the levers of the centering mechanism in the initial position; in fig. 5 - the same in the working position.

Claims

The proposed riveting hammer consists of a handle i with a MOM 2 trigger and a hammer 3 mounted inside it. The handle 1 is pivotally connected to the chamber 4, inside of which is located a cartridge 5, for example, from a building and assembly gun. The barrel 6, in which the hollow stepped hammer head 7 is moved, is connected via a shock absorber 8 to the housing 9 and the chamber 4. To secure the hammer 7 in the initial position, the pins 10 are included in the ring groove of the hammer, which are covered by a spring ring 11.; To the free end the barrel 6 is fixed to the hub 12 of the centering mechanism, which due to the key 13 does not have the ability to rotate relative to the barrel 6. Inside the sleeve 12 are mounted the axles 14, on which the levers 15 that can rotate the two shoulders, acting on; rivet bar 16. The outer ring 17 can be turned relative to the barrel 6 and bushings i 2 along the balls 18. The balls 18 are poured into the corresponding annular grooves through the holes during the assembly of the hammer, which are then plugged with plugs 19. The cage 17 is returned to its original position It is spring 20. Riveting hammer works as follows. The cartridge chamber 4 is placed in the cartridge 5, which is equipped with the necessary attachment of gunpowder. The hammer is brought to the rivet, the riveter holds the hammer with his right hand, and with his left hand turns the holder 7, which has a knurling on the outer surface clockwise. arrow (see Fig. 4). The yoke 17, when rotated, acts on one of the arms of the levers 15, causing them to rotate about the axes 14. In this case, the levers 15 act on the rod of the rivet 16, ensuring the centering of the hammer relative to the axis of the rivet. The hammer is pressed tightly against the bag. The riveter lets go of the 17, which is returned to its original position by the spring 20, and the levers 15 are carried away. In the initial position, the levers 15 occupy a position that is not obstructed by the movement of the striker 7 (Fig. 4). Then the riveter presses the trigger of mechanism 2, and the hit 3 pushes the cartridge cap 5. The powder ignites and the powder gases formed during combustion accelerate the firing pin 7, which is held in the initial position by the pins 10. By the end of the acceleration, the firing pin 7 acquires the required speed ( up to 140 m / s), and consequently also kinetic energy, sufficient for high-quality riveting-. Nin rod rivet. The striker 7 does not leave the bore 6 due to the braking force of deformation of the rivet, and after termination of the draft, with a collar on the trunk, which is connected via shock absorber B to the body 9. This prevents the barrel from collapsing in the presence of excess energy. Using a special ramrod, the striker is returned to its original position. Claim 1. A rivet hammer containing a barrel placed in the body with a stepped percussion head biased with the possibility of reciprocating movement, as well as a trigger mechanism mounted in the body, characterized in that, in order to increase the quality of riveting, it is equipped with a centering mechanism the rivet axis, mounted on the free end of the barrel, and spring-loaded pins for fixing the striker in the initial position, mounted in the holes provided in the barrel and entering the annular groove, made on the striker, as well as installed between the barrel and the shock absorber hammer housing.

2. Hammer according to claim 1, which is also distinguished by the fact that the mechanism for centering the hammer along the rivet axis is made in the form of a sleeve sitting at the end of the barrel, holding it with a clip installed with the possibility of relative rotation, and two-arm swivel arms acting on the workpiece fixed at equal distance from each other in the sleeve and passing each at one end through radial grooves made in the sleeve and in the cage.
