Abstract
The utility model discloses a kind of 620kW coal-winning machine rotor cage bar and end ring medium frequency welding induction coil structure, and comprise induction coil, described induction coil is coated by mica tape, and described induction coil is that 3 circles are spiral-shaped; Often there is gap between circle; Also comprise 2 gusset pieces in one plane, one of them gusset piece one is fixed on the end of induction coil, and another one gusset piece is fixed on U-shaped support plate, described U-shaped support plate is fixed on the another one end of induction coil; Described gusset piece connects with intermediate-frequency welding machine; Described induction coil is hollow structure, and the end of induction coil arranges water inlet and delivery port.The utility model has the advantages that: solve end ring thicker, end ring is heated uneven problem, improves product quality and production work efficiency.
Description
Technical field
The utility model patent relates to field of motor manufacturing, specifically the design of 620kW coal-winning machine rotor cage bar and end ring medium frequency welding induction coil.
Background technology
Rotor is the quality of the critical component in motor, rotor workmanship, directly has influence on quality and the life-span of motor manufacturing.As shown in Figure 1, end ring height about 70mm, prior art is segmentation welding to the end ring structure of 620kW coal-winning machine, and end ring is heated uneven, in order to ensure welding quality, needs to design a set of induction coil.
Utility model content
The purpose of this utility model is to provide a kind of medium frequency welding induction coil, to adapt to 620kW coal-winning machine rotor cage bar and end ring medium frequency welding technological requirement.Concrete technical scheme is as follows:
A kind of 620kW coal-winning machine rotor cage bar and end ring medium frequency welding induction coil structure, comprise induction coil, described induction coil is coated by mica tape, and described induction coil is that 3 circles are spiral-shaped; Often there is gap between circle; Also comprise 2 gusset pieces in one plane, one of them gusset piece one is fixed on the end of induction coil, and another one gusset piece is fixed on U-shaped support plate, described U-shaped support plate is fixed on the another one end of induction coil; Described gusset piece connects with intermediate-frequency welding machine; Described induction coil is hollow structure, and the end of induction coil arranges water inlet and delivery port.
Feature of the present utility model is: induction coil mica tape, with the characteristic of insulation high-temperature-resistant, in order to prevent being short-circuited between end ring and induction coil and between three circle induction coils, is wrapped by mica; The induction coil of the application is three circles, and head end and end have certain altitude, in order to ensure two gusset pieces in one plane, connects with medium frequency welding function, the supporting of one of them gusset piece U type support plate is got up, makes two gusset pieces in one plane.Because the end ring of 620kW coal-winning machine is thicker than normal end ring, individual pen heating is slow, so adopt three circles.
The utility model has the advantages that: solve end ring thicker, end ring is heated uneven problem, improves product quality and production work efficiency.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
In figure, 1 is the end ring of 620kW motor, and 2 is induction coils, and 3 is gusset pieces, and 4 is U-shaped support plates, and 5 is water inlets.
Embodiment
Illustrate the utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model comprises induction coil, and described induction coil is coated by mica tape, and described induction coil is that 3 circles are spiral-shaped; Often there is gap between circle; Also comprise 2 gusset pieces in one plane, one of them gusset piece one is fixed on the end of induction coil, and another one gusset piece is fixed on U-shaped support plate, described U-shaped support plate is fixed on the another one end of induction coil; Described gusset piece connects with intermediate-frequency welding machine; Described induction coil is hollow structure, and the end of induction coil arranges water inlet and delivery port.
