Abstract
The invention discloses a connection structure of a connecting rod and a ball lead screw and with a guiding function. According to the connection structure, the fact that the axis of a ball head lead screw is concentric with the axis of the connection structure can be forcefully guaranteed due to a positioning flange and a guide sleeve, therefore the defects that threads are deformed even damaged and the accidents that threads between the connecting rod and the ball head lead screw are not prone to regulate or equipment damage occurs caused by local oversize stress of the threads due to stress unbalance loading between the connecting rod and the ball head lead screw are avoided, meanwhile, the guide sleeve can be freely replaced after abrasion, and the fact that other important components are unlikely to scrap due to abrasion is guaranteed.
Description
Technical field
The present invention relates to a kind of metal forming machinery technology, specifically the bindiny mechanism of a kind of connecting rod of guide function and ball screw rod.
Background technology
The controllability of the threaded engagement of connecting rod and ball screw realizes the adjusting to forcing press operating mechanism.Yet often fragile in construction, be difficult to regulate, so cause between screw thread stressed generation unbalance loading, local pressure is excessive, even damages thereby cause deforming between screw thread.
Summary of the invention
The invention provides a kind of bindiny mechanism of connecting rod and ball screw rod of guide function, overcome existing stressed easy generation unbalance loading due to screw thread between connecting rod and ball screw, local pressure is excessive, causes the defective that deforms between screw thread and even damage.And the connecting rod that causes therefrom and the difficult adjusting of the screw thread between ball screw, or the accident of device damage.
For achieving the above object, the technical solution adopted in the present invention is: this invention comprises connecting rod, ball screw, locating flange, bolt, fairlead, positioning table.This invention is provided with a connecting rod, connecting rod inside and is provided with from the top down ball screw and positioning table, and described positioning table periphery is covered with a fairlead, and described connecting rod two ends have been bolted respectively locating flange 3.
Beneficial effect: because locating flange, fairlead can guarantee forcibly that the axle center of ball screw is concentric with the axle center of himself, so avoided that the screw thread local pressure that causes due to stressed unbalance loading between connecting rod and ball screw is excessive to be caused: the defective that deforms between screw thread and even damage, and the connecting rod that causes thus and the difficult adjusting of the screw thread between ball screw, or the accident of device damage, simultaneously, fairlead is free to change after wearing and tearing, guarantees that other strength member is unlikely to scrap because of wearing and tearing.
Description of drawings
Accompanying drawing 1 is schematic diagram of the present invention.
Shown in figure: 1. connecting rod, 2. ball screw, 3. locating flange, 4. bolt, 5. fairlead, 6. positioning table.
The specific embodiment
In the drawings, this invention comprises connecting rod 1, ball screw 2, locating flange 3, bolt 4, fairlead 5, positioning table 6.This invention is provided with a connecting rod 1, connecting rod 1 inside and is provided with from the top down ball screw 2 and positioning table 6, and described positioning table 6 peripheries are covered with a fairlead 5, and described connecting rod 1 two ends are fixed with locating flange 3 by bolt 4 respectively.
Because locating flange 3, fairlead 5 can guarantee forcibly that the axle center of ball screw 2 is concentric with the axle center of himself, so avoided that the screw thread local pressure that causes due to stressed unbalance loading between connecting rod 1 and ball screw 2 is excessive to be caused: the defective that deforms between screw thread and even damage, and the connecting rod 1 that causes thus and the difficult adjusting of the screw thread between ball screw 2, or the accident of device damage, simultaneously, fairlead 5 is free to change after wearing and tearing, guarantees that other strength member is unlikely to scrap because of wearing and tearing.
