Abstract

The invention provides a suction cup device which comprises a base, a cover plate and a plurality of air closing assemblies. A ventilation groove is formed in the top of the base, the cover plate fixedly covers the top of the ventilation groove in a closed mode, a ventilation cavity is formed between the ventilation groove and the bottom of the cover plate, and plurality of mounting grooves for mounting the air closing assemblies in a one-to-one correspondence manner are vertically and upwards formed in the bottom of the cover plate. The top of the cover plate is vertically and downwards provided with adsorption grooves right facing the upper portions of the mounting grooves in a one-to-one mode, and isolation layers are vertically provided with first ventilation holes and second ventilation holes. Each air closing assembly comprises a ventilation nozzle, a sealing valve body and an elastic piece, wherein the ventilation nozzle is fixedly installed in the corresponding mounting groove in a sealed mode, the sealing valve body is vertically and movably arranged at the top of the ventilation nozzle, the sealing valve body is located under the corresponding first ventilation hole, and the sealing valve body is provided with a ventilation position and an air closing position in the vertical direction. Elastic pieces abut against the positions between the sealing valve bodies and the ventilation nozzles, and the elastic pieces constantly drive the sealing valve bodies to move towards the ventilation positions.

Description

technical field [0001] The present application relates to the technical field of fixing devices for machine tool processing, in particular to a suction cup device. Background technique [0002] As we all know, in the process of processing workpieces by machine tools, it is often necessary to use suction cups to fix the workpieces to be processed. [0003] When the traditional adsorption suction cup fixes the workpiece, the workpiece is placed on the suction cup first, and the part of the suction cup that is not covered by the workpiece is sealed with a rubber strip to prevent the part of the suction cup that is not covered by the workpiece from being in the suction gas all the time. The state can also ensure that the suction cup has sufficient adsorption and fixing force on the workpiece. Therefore, when replacing or moving the workpiece, it is necessary to reciprocate the assembly and disassembly of the rubber strip many times, and the operation is very cumbersome and comp...
