Flexible Positioning and Clamping Mechanism for Cylindrical Parts

Abstract

The invention discloses a flexible positioning and clamping mechanism for cylindrical parts. The flexible positioning and clamping mechanism comprises a main mounting plate, an axial compressing assembly, a radial positioning and clamping assembly and a camshaft assembly; the camshaft assembly comprises a main shaft, a push-out cam and a downward-pressing cam, wherein the main shaft rotates to drive the push-out cam and the downward-pressing cam to rotate together; the axial compressing assembly comprises a plurality of axial compressing units, wherein each axial compressing unit comprises a downward-pressing shaft, a downward-pressing ring, a downward-pressing arm and a first compression spring, and the downward-pressing cam rotates to drive the downward-pressing shafts to move up and down so that the downward-pressing shafts can compress workpieces; and the radial positioning and clamping assembly comprises a plurality of radial positioning and clamping units, wherein each radial positioning and clamping unit comprises a claw hook mounting plate, a claw hook, a contact wheel, a second compression spring and a retractable spring seat, and the push-out cam rotates to drive the clawhooks to move in the radial direction so that the radial positioning and clamping of the workpieces can be realized. The flexible positioning and clamping mechanism has the advantages that the workpieces can be positioned simultaneously in the process of clamping and grabbing the workpieces.

Description

technical field [0001] The invention relates to the technical field of mechanical equipment, in particular to a flexible positioning and clamping mechanism for cylindrical parts. Background technique [0002] In the dual-clutch automatic transmission intelligent assembly line, it is necessary to grab and carry the stacked friction plates and steel plates (which can be regarded as a cylindrical assembly formed by stacking thin sheets), and the stacked The friction plate and steel plate must be positioned to ensure the positional relationship between the friction plate and the steel plate without relative movement or relative rotation. [0003] In the prior art, most of the grasping mechanisms for cylindrical workpieces only have the functions of grasping and handling, but the positioning function cannot be guaranteed. The grabbing mechanism with the grabbing function often cannot meet the requirements of use, and cannot guarantee the relative positional relationship of the w...

[0003] In the prior art, most of the grasping mechanisms for cylindrical workpieces only have the functions of grasping and handling, but the positioning function cannot be guaranteed. The grabbing mechanism with the grabbing function often cannot meet the requirements of use, and cannot guarantee the relative positional relationship of the workpiece; moreover, the cylinder is often used as the clamping power source, and the clamping stability is easily affected by the change of the air source pressure, and the automatic clamping Clamping is often only aimed at clamping one or several similar workpieces, has poor compatibility, and is highly dependent on power sources (air source, power supply); when multiple simultaneous actions are required, multiple cylinders are often used action to achieve
