Description

Technical Field

[0001] The utility model relates to the technical field of workpiece processing, in particular to a vacuum adsorption jig for processing non-magnetic workpieces. Background Art

[0002] When processing non-magnetic workpieces (non-magnetic stainless steel, nylon, PET, engineering plastics, etc.), they cannot be held on the suction disk and can only be clamped with pliers or pressed with a pressure plate. However, these methods will cause deformation of the workpiece. The vacuum adsorption fixture mainly fixes the workpiece on the fixture through the effect of vacuum adsorption, replacing the traditional clamping and top fixing methods, and plays a certain protective role for the workpiece.

[0003] After searching, the Chinese patent publication number is CN211332865U, which discloses a vacuum adsorption fixture. Through the waste chip filtering mechanism, the workpiece can be placed on the waste chip filtering mechanism for processing. When the vacuum pump is adsorbed through the vacuum connection hole, a certain suction force can be generated in the ventilation shaft to adsorb the workpiece, and it is filtered through the filter element in the ventilation shaft to prevent the vacuum pump from being blocked. Through the buffer mechanism, when the workpiece is processed, the rocker on the buffer mechanism can be shaken, so that the push rod in the buffer mechanism pushes the fastening rod forward, and the workpiece in the adsorption fixture body is tightened by the buffer spring, which can play a buffering role.

[0004] During use of the above patent, after the filter element filters the waste chips, the waste chips will accumulate in the ventilation shaft. Although the waste chips can be isolated, part of the suction force of the vacuum pump will be cut off, thereby reducing the suction force of the vacuum pump on the workpiece, and then when the workpiece is processed, it will cause the workpiece to deviate, and the waste chips stored in the ventilation shaft are not easy to clean.
