The invention discloses a cutter holder clamping mechanism of a vertical milling machine. The technical scheme is as follows: a clamping body is mounted at the lower part of a ram; oil cylinders are arranged at the positions of four corners of the ram and the clamping body respectively; and a clamping and loosing oil inlet pipeline of each oil cylinder is connected with the same oil supply pipeline. The clamping mechanism between the oil cylinders and a conical body is a clamping piston; and the conical body is connected with a turning cutter holder through a bolt. A loosening in-place control mechanism of the clamping mechanism is composed of an inductive block and an inductive switch; a hydraulic system also comprises a hydraulic lock and a pressure relay of a collection device of clamping in-place pressure signals. The cutter holder clamping mechanism of the vertical milling machine, provided by the invention, has the advantages that: the connection rigidity between the ram and the cutter holder of the vertical milling machine is greatly improved by the cutter holder clamping mechanism, and the loading and turning capability of a machine tool is improved. The high-rigidity cutter holder clamping mechanism is utilized to enable the turning capability of the ram to reach 120kN; and meanwhile, the manufacturing cost of the cutter holder clamping mechanism is only 1 / 3 that of the traditional structure and the economic benefit is remarkable.
Description
technical field [0001] The invention relates to a tool holder clamping mechanism of a vertical turning and milling machine. Background technique [0002] In today's machine tool industry, there are many types of connection structures between the turning and milling machine ram and the turning tool holder. The structure generally adopts the combination of the end tooth plate and the Berg cylinder. This structure has high cost and low connection stiffness, which cannot meet the needs of machine tools. Heavy duty turning requirements. Contents of the invention [0003] The new object of the present invention is to provide a tool holder clamping mechanism for a vertical turning and milling machine, which can solve the problem of low rigidity of the connection between the ram and the tool holder, and at the same time greatly reduce the manufacturing cost. [0004] The technical scheme adopted by the present invention is: the clamping body is installed on the lower part of the ...
