Problems solved by technology

[0002] An important feature of the magnetic pole plate and fan-shaped plate is that one end surface is an outer arc surface, and the shape and position tolerance of the arc surface is relatively high. If the forged cylinder blank is used, the outer circle is turned and then cut to a single piece. The utilization rate of raw materials is low, the processing cost is high, and the larger the diameter of the outer arc of the workpiece, the more serious the material waste
If the process of CNC milling of forged square blanks is adopted, the processing time is longer, the cost is high, the efficiency is low, and the dimensional accuracy of the outer arc is difficult to control
This kind of product is often used in pairs or groups of four, and it is necessary to ensure that the outer arc surface of the same group of workpieces is assembled in the same size. If the processing method of arc milling is used, the consistency of the outer arc surface of the workpiece used in the same group is poor. And it is difficult to achieve high profile and roughness

Embodiment Construction

[0023] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0024] Such as figure 1 and figure 2 As shown, a slewing bracket includes a central piece 1, the central piece 1 is a seamless steel pipe, the two ends of the central piece 1 are provided with a circular cover plate 2, and the outer side of the circular cover plate 2 is provided with A plurality of triangular ribs 3 are used to improve the rigidity, and multiple sets of fixing parts are arranged on the outside of the central part 1, and the fixing parts include at least two trapezoidal reinforcing ribs 4 on the same straight line, and the trapezoidal reinforcing ribs 4 is provided with a vertical plate 5, which increases the strength of the trapezoidal rib 4, and the narrow side of the trapezoidal rib 4 is welded to the center piece. After welding, stress relief annealing is required to eliminate the welding stress. The width of the trapezoid...

Abstract

The invention discloses a technological method for processing an outer circular-arc surface and a rotary bracket used for the technological method. The rotary bracket comprises a central part which is a seamless steel pipe, wherein circular cover plates are arranged at the two ends of the central part; a plurality of triangular rib plates are arranged at the outer sides of the circular cover plates; and a plurality of groups of fixed parts are arranged at the outer side of the central part. In a processing process, the technological method is convenient in measuring the diameter of an outer circle of a workpiece, so that circular-arc-surface dimension tolerance can be effectively guaranteed; and a lathe is used for processing, so that the outer circle can be conveniently polished, and relatively large steps are prevented from being reserved in a circular arc surface processed by a milling machine; and the technological method is used for processing the circular arc surface of the workpiece, so that drawing requirements can be quickly and simply reached.

Description

technical field [0001] The invention relates to a process method and process equipment for processing the outer arc surfaces of workpieces such as generator shaft magnetic pole plates and sector plates. Background technique [0002] An important feature of the magnetic pole plate and fan-shaped plate is that one end surface is an outer arc surface, and the shape and position tolerance of the arc surface is relatively high. If the forged cylinder blank is used, the outer circle is turned and then cut to a single piece. The utilization rate of raw materials is low, the processing cost is high, and the larger the diameter of the outer arc of the workpiece, the more serious the material waste. If the process of CNC milling of forged square blanks is adopted, the processing time is longer, the cost is high, the efficiency is low, and the dimensional accuracy of the outer arc is difficult to control. This kind of product is often used in pairs or groups of four, and it is necessa...
