Horizontal feeding device of numerical control vertical lathe with maximum machining diameter of 2.5m

Abstract

The invention relates to a horizontal feeding device of a numerical control vertical lathe with maximum machining diameter of 2.5m. The device comprises a cross beam, a cross beam end plate, a servo motor and a screw rod, wherein the cross beam end plate is mounted on the end face of the cross beam, and the servo motor and the screw rod are mounted on a same side of the cross beam end plate. The horizontal feeding device is characterized in that the cross beam end plate is provided with a distance adjusting slide seat and a shaft sleeve; the servo motor is fixedly mounted on the cross beam end plate through the distance adjusting slide seat; the screw rod is mounted in the shaft sleeve through a bearing and a driven belt wheel is fixedly arranged at the end part of the screw rod; the servo motor is fixedly connected with a driving belt wheel; the speed reducing ratio of the driving belt wheel to the driven belt wheel is 1: 4 and the central distance between the driving belt wheel and the driven belt wheel is 400-420mm; the driving belt wheel and the driven belt wheel are synchronously connected through a synchronous toothed belt; and at least seven teeth are arranged inside a corner covering region formed by the synchronous toothed belt on the driving belt wheel and are engaged with one another.

Description

technical field [0001] The invention relates to a horizontal feeding device, in particular to a horizontal feeding device of a numerical control vertical lathe with a maximum workpiece diameter of 2.5m. Background technique [0002] The horizontal feed device is the main component of the horizontal (X-axis) feed system of the CNC vertical lathe. As a power transmission unit, it transmits the rotary motion of the servo motor to the ball screw to realize the horizontal linear motion of the tool post. In the process of numerical control transformation of ordinary C5225 products, we found that they generally adopt the complex, inefficient and low-precision transmission chain of the old-fashioned structure of the feed box-T-type screw, and if the reducer such as ZF is used, although The performance is high, but there are problems such as high price and difficult maintenance. At present, the industry is eager to develop a new product that can not only meet the requirements of use,...

Problems solved by technology

In the process of CNC transformation of ordinary C5225 products, we found that they generally use the complex, inefficient, and low-precision transmission chain of the old-fashioned structure of the feed box-T-shaped screw, and if the ZF and other reducers are used, although The performance is high, but there are problems such as high price and difficult maintenance. At present, the industry is eager to develop a new product that can not only meet the requirements of use, but also reduce costs and maintenance costs, and the structure is simpler, clearer, and easier to maintain. more convenient

[0003] Although the synchronous toothed belt has reliable transmission and strong impact resistance in the transmission mechanism, because the teeth compounded on the transmission belt are easily damaged during the power transmission process, it is generally used for constant speed or small power transmission with relatively high speed accuracy requirements. In the transmission equipment, at present, this transmission method is used for the increase and decrease transmission system with a relatively large speed ratio, and at the same time, the occasion of a large output power, for example, the reduction ratio is 1:4, and the maximum processing diameter is 2.5 m CNC vertical lathe application, there is no report
