Self-weight pressure maintaining mechanism

Abstract

The invention relates to a self-weight pressure maintaining mechanism. The self-weight pressure maintaining mechanism comprises a connecting seat and a pressing part; a limiting surface for bearing a workpiece is arranged at the top end of the connecting seat; the pressing part is positioned above the limiting surface, wherein the pressing part comprises a pressure head module and at least two groups of counterweight modules, and the counterweight modules are downwards pressed at the top end of the pressure head module, so that the pressure head module is downwards pressed on the workpiece, and the workpiece is driven to be adjusted from an inclined state to a balanced state. When the workpiece is in the inclined state, the counterweight modules press the pressure head module downwards to enable the pressure head module to press the inclined vertex of the workpiece downwards, and then the workpiece is driven to deflect to be in the balanced state; when the workpiece is in the balanced state, each group of counterweight module acts in a corresponding area where the pressure head module presses the workpiece, the position of the workpiece is adjusted through the self-weight pressure maintaining mechanism, pressure maintaining is carried out on the workpiece, and the mounting precision of the workpiece is guaranteed.

Description

technical field [0001] The invention relates to the field of non-standard automatic assembly, in particular to a self-weight and pressure-maintaining mechanism. Background technique [0002] In the field of non-standard automation, in the assembly process, when no less than two parts are pressed together to form a whole, it is well known to use a pressure maintaining mechanism to maintain pressure on the overall workpiece. The inventor found that the existing pressure maintaining The mechanism has at least the following problems in the process of holding the thin plate parts: [0003] First of all, some thin-plate parts are not flat surfaces, and their surfaces are curved, so it is difficult to ensure the accuracy of assembly during the assembly process; because the surface of the workpiece is curved, the contact area of ​​the surface is small during the assembly process, and the deflection of the thin-plate parts often occurs When the situation arises, for this reason, it ...
