(54) УСТРОЙСТВО ДЛЯ ЗАЖИМА ДЕТАЛЕЙ(54) DEVICE FOR CLAMPING DETAILS

II

Изобретение относитс к области станкостроени .The invention relates to the field of machine tools.

Известно устройство дл зажима деталей , в корпусе которого размещен подвижный в осевом направлении зажимной механизм выполненный в виде втулки, несущий подпружиненные торцовые прихваты, и механизм. их перемещени i .A device for clamping parts is known, in the case of which there is an axially movable clamping mechanism made in the form of a sleeve, carrying spring-loaded end clamps, and a mechanism. their movements i.

Недостатком этого устройства вл ютс узкие его технологические возможности .The disadvantage of this device is its narrow technological capabilities.

Целью изобретени вл етс расширение технологических возможностей.The aim of the invention is the expansion of technological capabilities.

Указанна цель достигаетс тем, что механизм перемещени торцовых прихватов выполнен в виде съемной конусной оправки с ключом на торце и paaiyteuieHKpro в корпусе винта с отверстием под ключ.This goal is achieved by the fact that the mechanism for moving the end claws is made in the form of a detachable conical mandrel with a key on the end and a paaiyteuieHKpro in the housing of a screw with a key hole.

На чертеже изображено устройство дл зажима деталей, разрез. .The drawing shows a device for clamping parts, section. .

Устройство состоит из корпуса 1, в котором размещен подвижный в осевом направлении зажимной механизм, выполненный в виде втулки 2, несуишй подпру;жиненные пружиной 3 торцовые прихваты 4, направл ющие которых выполнены под углом к радиальной составл ющей, перемещаемые съемно.й конусной оправкой 5 с ключом 6 на ее торце, взаимодействую .щим с винтом 7, в котором выполнено отверстие под ключ 6, а между втулкой 2 и корпусом 1 размещена упруга шайба 8.The device consists of a housing 1 in which a clamping mechanism movable in the axial direction, made in the form of a sleeve 2, is not supported by a spring loaded spring 3 butts 4, the guides of which are made at an angle to the radial component, moved by a removable taper mandrel 5 with a key 6 at its end, interacting with a screw 7, in which a key hole 6 is made, and an elastic washer 8 is placed between the sleeve 2 and the housing 1.

Работает устройство следующим образом .The device works as follows.

Claims

Item 9 is mounted on the housing 1. Insert the mandrel 5, which with its tapered portion extends the end clamps 4 from the center, compressing the spring 3, and the key 6, made on the mandrel face, interacts with the screw 7. When screwing the screw 7, the housing 1 of the device together the end claws 4 are moved in the axial direction, squeezing the elastic ring 8 until the end clamps 4 press the part 9 to the end face. After that, the mandrel 5 is removed. When unclamping the part, the screw 7 is unscrewed, the device body t together with the end clamps 4 under the action of the elastic washer 8 moves in the eight direction, freeing the clamp. 4, which, under the action of the springs 3, retreat to the center. Item 9 is released. In connection with the fact that the end tacks are made by a detachable cone mandrel, the device can be used for clamping parts at the ends not on machines that are not equipped with pneumatic and hydraulic drives, as well as in cases when conditions of operation of the device. 1 2 8 6 Claims of invention for clamping parts c. the central hole, in Koptiyce of which there is a movable axially movable and mechanism, made in the form of a sleeve, carrying spring-loaded end clamps, and the mechanism of their movement, differs from the fact that, in order to expand the technological capabilities, the mechanism for moving the end clamps is made in the form of a removable cone mandrel with a key on the end and placed in the housing with a screw hole wrench.
