Description

Изобретение относитс к области машиностроени и может быть использовано в различных устройствах и механизмах дл креплени деталей, например втулокj осей, штоков, и других элементов в труднодоступных местах .The invention relates to the field of mechanical engineering and can be used in various devices and mechanisms for fastening parts, for example bushings, axles, rods, and other elements in hard-to-reach places.

Известно устройство дл измерени деталей, содержащее двуплечий . рычаг, установленный с- возможностью поворота вокруг оси винта. При воздействии усилий на одно плечо, другое плечо зажимает деталь C JНедостатком данного устройства вл етс то, что оно не обеспечивает надежного креплени в результате незначительных усилий, возникающих при воздействии на деталь. Кроме того , оно не обеспечивает креплени в труднодоступных местах, что сужает .технологические возможности устрой ства.A device for measuring parts containing two shoulders is known. lever installed with the possibility of rotation around the axis of the screw. When acting on one shoulder, the other shoulder clamps the part C. The disadvantage of this device is that it does not securely fasten as a result of the slight force that occurs when the part is exposed. In addition, it does not provide fastening in hard-to-reach places, which limits the technological capabilities of the device.

Указанна цель достигаетс тем, что в разъемном зажимном соединении двух деталей, содержащем установленный в отверстии одной из соедин емых This goal is achieved by the fact that in a detachable clamping connection of two parts, which is installed in the hole of one of the connected

25 of this friend, the connected part is made with a groove, interacting with the end of the clamping element, and on the bolt the size | on the threaded sleeve with a convex end on the side of the clamping element 30. In addition, the sleeve is installed with the possibility of locking the restrictive element rigidly mounted on the bolt. Fig, 1 shows the device, a general view; in fig. 2 shows section A-A in FIG. one; in FIG. 3 is a section b-B in FIG. one; in fig. 4 shows a section B-B in FIG. 1. The device contains a part 1, in the hole of which a bolt is installed. In the cavity of part 1 a clamping element 3 is installed, made in the form of a lever, one arm of which is fixed on the bolt 2 with the possibility of limited rotation around the axis of the latter. To limit the rotation of the clamping element 3, a groove 4 is made in the part 1. The other lever arm is adapted to enter the ave. provided on part 5 notch b. In order to insert the end of the lever into the groove b, lead-in facets 7 and 8 are made on it. The clamping element 3 is installed with a possibility of swinging relative to the line of contact K with the body 1 (Fig. 1). The bolt 2 is screwed on the sleeve 9, which fits into the corresponding groove of the clamping element 3. The end of the nut for linear contact with the fixed element is made in the form of a convex surface, for example, cylindrical. The sleeve 9 is installed with; the locking ability is limited by the limiting element 10 fixed to the bolt, for example, with a crown nut fixed with a cotter pin 11. The device works as follows. During installation, the bolt 2 is turned counterclockwise until the sleeve 9 is screwed with the restriction element 10 and tightened. After that, the bolt 2 is rotated clockwise, while the clamping element 3 is rotated together with the sleeve 9 and is inserted into the groove of the part 5. sleeve 9 moves upwards and transfers the force to clamping element 3, as a result of which clamping element is tightened to the bracket 1. The clamping force is fixed, part 5 is proportional to the tightening torque of the bolt 2. Dismantling is performed by rotating 2 is the counter-clockwise until it stops. The proposed device makes it possible to fix round parts of a practically unlimited range of diameters and details of other configurations, which greatly enhances its technological capabilities. Claim 1. A detachable clamping connection of two parts comprising a bolt installed in the hole of one of the joined parts and a clamping element fixed at the end of the bolt with the ability to swing and interact with co-i with the same parts, characterized in that In order to expand technological capabilities, the outer surface of the clamping element from the side of one of the parts to be joined is made in the form of mating inclined surfaces, forming a protrusion in the interface area, offset from the axis The bolt with this other connecting part is made with a groove that interacts with the end of the clamping element, and the bolt houses a threaded sleeve with a convex end on the side of the clamping element. 2. The device according to claim 1, which differs from I in that the sleeve is installed with the possibility of locking the restrictive element rigidly fixed on the bolt.
