Embodiment Construction

[0039] The present invention will be further described below in conjunction with accompanying drawing:

[0040] like Figure 1 to Figure 9 As shown, a stator core coil space half-mortise and tenon rotary drying tooling, including a lower tooling 1 and an upper tooling 2;

[0041]The lower tooling 1 includes two protective rings 3, and four rotating disks 4 are evenly distributed between the two protective rings 3. Both the protective rings 3 and the rotating disks 4 are designed as arc-shaped plates and arranged in parallel and coaxially. The radius of the inner arc of the protective ring 3 is equal to that of the rotating disk 4, and the radius of the outer arc of the protective ring 3 is smaller than the radius of the outer arc of the rotating disk 4; two positioning plates 14 are evenly distributed between the first and second rotating disks 4 , each positioning plate 14 is covered and fixed with a mounting plate 5, two positioning plates 14 are evenly distributed between ...

Abstract

The invention is a semi-mortise and tenon rotary drying tool for stator core coil space, which solves the problems of difficult installation and disassembly, long installation time, easy loss of insulating paint and the like in the existing rotary drying tool. The tooling of the present invention is composed of the lower tooling and the upper tooling with the same structure butt joint fastening, and the upper and lower tooling are composed of a protective ring, a rotating disc, a positioning plate, a mounting plate, a longitudinal beam, a tightening plate, bolts and the like. Each matching part of the tooling of the present invention is a non-complete mortise and tenon structure, which is convenient for cleaning the retained insulating paint, but after the overall combination, the structural rigidity of the tooling is used to form an open mortise and tenon structure, so that the positioning of the tooling is accurate and reliable . The efficiency of the tooling of the present invention is more than 5 times higher than that of the original tooling, because it shortens the time for the product to be rotated from the paint tank to the oven, reduces the loss of insulating varnish, greatly improves the product quality, and solves the urgent need for production. The labor intensity of the operator is reduced.

Description

technical field [0001] The invention relates to the technical field of motor stator manufacturing, in particular to a semi-mortise and tenon rotary drying tool for stator iron core coil space. Background technique [0002] With the breakthrough of frequency conversion technology, AC motors have developed rapidly. A large number of stator armatures of motors have adopted the process of dipping the iron core coils into the wires, and then shrinking the frame. In order to improve the quality of dipping paint and reduce insulation The loss of lacquer is wasted, and the baking process mainly adopts the rotary baking method. In order to meet this requirement, a rotary baking tool must be designed. In order to ensure product quality and reduce the cost of tooling, it is necessary to design a rotary baking tool that is easy to install and suitable for a variety of products. [0003] The existing baking equipment includes: 1) Install the equipment at both ends of the iron core coil,...
