Description

Изобретение относитс к грузоподъемным механизмам, а именно к передвижным монтажным кареткам дл монтажа различных частей автомашин.The invention relates to lifting mechanisms, namely to mobile mounting carriages for mounting various parts of motor vehicles.

Известна перед:(вижна монтажна каретка, содержаща установленную на раму шасси платформу, привод пе-. ремещени платфоркщ, включанмций в себ направл к цие, на которых установлены ползуны с вмонтированными в них гайками, имеющими разнонаправленную резьбу, с которыми св зан винт вертикального перемещени платформы , полый вал с приводной руко ткой , посредством шаровой опоры установленный в раме шасси, размешенный в указанном валу полый шток, в котором смонтирован винт горизонталь Ного перемещени платформы с приводной руко ткой 1.Known before: (a visually mounted carriage containing a platform mounted on the chassis frame, a drive for moving the platforms, inclination to the engine, on which sliders with nuts mounted in them are mounted, with differently directed threads, with which the vertical movement screw is connected a platform, a hollow shaft with a drive handle, through a ball bearing mounted in the chassis frame, a hollow rod displaced in the indicated shaft, in which a screw is mounted. A horizontal movement of the platform with a drive handle 1.

Однако монтажна каретка характеризуетс сравнительно сложной конструкцией и недостаточной надежностью работы.However, the mounting carriage is characterized by a relatively complex structure and insufficient reliability of operation.

Цель изобретени - упрощение конструкции каретки и повьоиение надежности работы.The purpose of the invention is to simplify the carriage design and improve operation reliability.

Дп достижени поставленной цели полый вал снабжен прикрепленной к нему шпонкой, а полый шток одним кон-.Dp achievement of the goal, the hollow shaft is provided with a key attached to it, and the hollow rod with one cone.

дом взаимосв зан с винтом вертикального перемещени платформы, на внут-. ренней. его поверхности выполнена резьба, контактирующа с нарезкой винта горизонтального перемещени , а на наружной поверхности выполнен паз, взаимодействующий со шпонкой полого вала.the house is interconnected with the screw of the vertical movement of the platform, to the inside. Rennie. its surface is threaded in contact with the cutting screw horizontal movement, and on the outer surface of the groove, interacting with the key of the hollow shaft.

Передвижна каретка содержит полый вал 1, встроенный своей шаровой опо15 рой в корпус 2 шасси с помощью конусных шайб 3 и крышек 4, размещенный во внутренней полости вала 1 шток 5, зафиксированный от вращени относительно вала 1 шпонкой 6, винт 7 The movable carriage contains a hollow shaft 1, which is integrated with its ball joint into the chassis body 2 by means of conical washers 3 and caps 4, placed in the inner cavity of the shaft 1 rod 5, fixed from rotation relative to shaft 1 by key 6, screw 7

20 горизонтального перемещени , руко тки 8 и 9, шарнирную муфту 10, соедин ющую шток 5 с винтом 11 вертикального перемещени , гайки 12 и 13, ползуны 14 и платформу 15.20 horizontal movement, handles 8 and 9, a hinge coupling 10 connecting the rod 5 with the vertical movement screw 11, nuts 12 and 13, sliders 14 and platform 15.

Механизм управлени работает следующим образом.The control mechanism works as follows.

Claims

The lifting of the slide is made by using the handle 8, horizontal movements are performed by turning the handle 30 (9.). With a large carrying capacity of the handwheel assembly carriage, it is possible to replace it with ratchets with force handles). When the handle 8 rotates, the control mechanism rotates as a whole in the ball bearing and through the rod 5 and the coupling 10 transmits rotation to the vertical movement screw 11, which, tightening or unscrewing the nut 12 and 13, through the sliders 14 moves the plates | 15 in the vertical plane. In this case, the axial force on the shaft 1 is absent and the frictional forces in the ball bearing are minimal. The rotation of the rod 5 together with the shaft 1 does not affect the horizontal screw support. When the handle 9 is inserted, and together with it the screw 7, the rod 5 is axially moved relative to the shaft 1. This force is transmitted through the clutch 10 to the screw 11 and through it to the platform 15, moving it in the horizontal plane Screw 7, resting five the protrusion of the shaft 1 transfers the axial force to the ball shaft support, reliably pinching it from turning in the cone washer 3, thereby eliminating the effect of the screw pair of horizontal movement on the screw of the vertical motion, since the forces of friction in the ball bearing are much greater than the forces of the screw pair rod 5 and screw 7. The hinge coupling 10, which connects screw 11 with rod 5, allows the screw relative freedom of movement in the vertical plane during carriage deformations occurring under load, especially with large carriage dimensions, when it is relatively difficult to secure the system. Thus, due to the fact that the propeller pair of the transverse tube is located inside the hollow shaft. pivotally connected to the screw, and the shaft with its ball bearing is placed between two conical washers installed in the chassis housing, it became possible to eliminate the mutual influence of the screws of the vertical and horizontal movement of the platform, as well as to simplify the design and increase the reliability of its operation. Claims of the invention A movable assembly carriage comprising a platform mounted on a chassis frame, a platform movement actuator, including guides on which sliders are installed with nuts mounted in them, with multidirectional threads, with which the platform vertical screw is connected, a hollow shaft with a drive handle by means of a ball bearing mounted in the chassis frame, a hollow rod is placed in the shaft, in which a screw of horizontal movement of the platform with a driving handle is mounted In order to simplify the design and increase reliability, the hollow shaft is provided with a magazine attached to it, and the hollow rod is interconnected with the vertical movement screw of the platform with one end, on its inner surface there is a thread, in contact with the threading of the horizontal movement screw; and on the outer surface there is a groove interacting with the key of the hollow shaft.
