Clamping device for numerical control machine tool machining

Abstract

The invention discloses a clamping device for numerical control machine tool machining. The clamping device comprises a plurality of sets of supporting columns, a rotating shaft, a rotating disc, first mounting plates, two sets of top plates and a second mounting plate, wherein the plurality of sets of supporting columns are connected with a base and a plurality of sets of assembling plates respectively; the rotating shaft is rotationally connected with the base, and is in transmission connection with a first driving device; a moving assembly for driving the two sets of first mounting plates to move is arranged on the rotating disc connected with the rotating shaft; two sets of lower clamping parts are arranged on the end face of each set of first mounting plates in a sliding manner; two sets of first telescopic devices for driving the two sets of lower clamping parts to move are arranged on the first mounting plates; the first mounting plates are connected with the top plates throughconnecting rods; a plurality of sets of lifting devices for driving the two sets of second mounting plates to move are respectively arranged on the two sets of top plates; two sets of upper clamping parts are arranged on the end face of each set of second mounting plates in a sliding manner; and two sets of second telescopic devices for driving the two sets of upper clamping parts to move are arranged on the second mounting plates. By means of the clamping device, workpieces with square or circular cross sections can be rapidly clamped.

Description

technical field [0001] The invention relates to the technical field of numerical control machine tools, in particular to a clamping device for numerical control machine tool processing. Background technique [0002] CNC machine tool is the abbreviation of numerical control machine tool, which is an automatic machine tool equipped with a program control system. The control system can logically process programs with control codes or other symbolic instructions, decode them, express them in coded numbers, and input them into the numerical control device through the information carrier. After calculation and processing, the numerical control device sends out various control signals to control the movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing; when using the numerical control machine tool to process cuboid or cylindrical workpieces, it is necessary to use The clamping device clamps and fixes the above-me...

Problems solved by technology

After calculation and processing, the numerical control device sends out various control signals to control the movement of the machine tool, and automatically process the parts according to the shape and size required by the drawing; when using the numerical control machine tool to process cuboid or cylindrical workpieces, it is necessary to use The clamping device clamps and fixes the above-mentioned workpieces to facilitate CNC machine tools to process them. However, the existing clamping devices are inconvenient to use. When clamping workpieces with different cross-sections, it is necessary to constantly replace the parts of the clamping device. , time-consuming and labor-intensive, greatly reducing the production efficiency of workpieces; for this reason, this application proposes a clamping device for CNC machine tool processing
