Milled composite ram apparatus

Abstract

The invention discloses a turn-milling compound ram device which comprises a motor, a gear box, an output shaft, and mechanisms and pipelines which are connected with an accessory head. The turn-milling compound ram device is characterized in that the parts are integrated in the casing of the ram. The motor and a speed reducer are arranged in the upper end of the casing. The external gear of the output shaft is connected with the gear box. The lower opening of the gear box is connected with a comparatively short power output shaft. The maximum output power reaches 52KW; torque moment reaches 2400Nm; and rotary speed reaches 3150r / min. the power output shaft is connected with a connecting structure. A connector is provided with a centering short taper, two wedge-shaped bonding transmission torque moments and four mechanical autolocking tightening mechanisms. The ram is provided with liquid, gas and electric pipe lines on the wall of the casing. The end connector of the ram is provided with line clutches thereof. The pipe lines and mechanical parts are connected automatically with the accessory head of operating parts. The turn-milling compound ram device has a compact internal structure in the ram device, has a comparatively short output shaft, improves power output ability, and has a small volume of the ram device with the section size of 280mm long and 240mm wide. The connections between the ram and the operating equipment such as a cutter, a core milling head and so on can realize the purposes of general use and automatic connection.

Description

technical field [0001] The utility model relates to the manufacture of mechanical equipment, in particular to a composite ram device used for a large vertical turning and milling center and a gantry boring and milling machine. Background technique [0002] The ram is a very critical part of the turning and milling center. It drives the tool to move and provides operating power for boring, drilling and milling functions. The structure and performance of the ram are directly related to the performance of the machine tool. At present, the power rams of domestic large-scale vertical turning and milling centers and gantry machining centers mostly adopt the structure of external power motor and reducer, that is, the power motor and reducer are installed on the top of the ram, and then pass through the ram The long slender transmission shaft transmits to the lower part of the ram, and then to the fixed tool attachment head. Since the power is transmitted through the slender transm...

AI Technical Summary

Problems solved by technology

The power motor and reducer of this kind of ram structure occupy a relatively large space outside the ram shell, and there are pipelines such as lubrication, cooling, and power transmission between the ram and the accessory head, which must be connected manually or semi-automatically, with a low degree of automation. Restricts the working ability of the machine tool
