Abstract
Description
Technical Field
[0001] The utility model relates to the field of production equipment maintenance, in particular to a magnetic powder brake disassembly device. Background Art
[0002] The wire rod is often compared to the "heart" of a generator because the reliability and lifespan of a large generator are largely determined by the quality of its insulation. Existing equipment features two cylindrical magnetic powder brakes installed on the taping head, measuring approximately 115 mm in base diameter and 48 mm in height. These brakes adjust the taping tension by sending signals from a controller to control the voltage, thereby automatically adjusting the tension during the wire rod wrapping process. However, routine maintenance of the equipment often requires removal of the magnetic powder brakes to facilitate repairs of other components. The compact assembly and limited space between the magnetic powder brake and the taping reel connection shaft can easily damage the brakes, leading to magnetic powder leakage and even unusability, making removal extremely difficult. Summary of the Invention
[0003] In view of this, the purpose of this utility model is to provide a magnetic powder brake disassembly device, which has the advantages of novel style, simple structure, low cost, safety and reliability, strong versatility and easy promotion.
[0004] The technical solution adopted by the utility model is: a magnetic powder brake disassembly device, which consists of a main body plate, a push rod, a positioning rod, a compression spring, a spring force adjustment nut, and a push ball. The push rod is an external thread structure and is threadedly connected to the inner hole of the main body plate; the positioning rod and the push rod are installed in the corresponding three position holes of the main body plate in the same direction, the compression springs are respectively sleeved on the three positioning rods of the main body plate, the positioning rod is threadedly connected to the spring force adjustment nut, and the push ball is embedded in the end of the push rod bolt.
[0005] As a further solution of the present invention: the main body plate adopts a three-point flying saucer-shaped structure, and has a processed stress relief hole, the inner hole is an internal thread structure, and the mounting hole of the positioning rod is a through hole.
[0006] Compared with the prior art, the beneficial effects of the present invention are:
[0007] The design has been fully considered. First, in order to ensure that the force is always balanced during the disassembly of the magnetic powder brake, the flying saucer-shaped main plate adopts a three-point positioning structure and is processed with three stress relief holes. The three positioning rods are installed with compression springs. Under the action of the spring force, the main plate can remain parallel to the bottom surface of the magnetic powder brake. Second, in order to prevent damage to the appearance of the bag disc connecting shaft during the disassembly process, a top bead is embedded at the end of the top rod bolt to achieve non-destructive disassembly. The utility model has a novel style, a simple and practical structure, and a low cost. It can also be used as a reference for other similar disassembly devices. It has strong versatility and is easy to promote. BRIEF DESCRIPTION OF THE DRAWINGS
[0008] Figure 1 This is a schematic diagram of the structure of the magnetic powder brake disassembly device. DETAILED DESCRIPTION
[0009] The technical solutions of the present application are further described in detail below in conjunction with specific embodiments. To make the purpose, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different structures.
[0010] like Figure 1 As shown, the utility model is a magnetic powder brake disassembly device, which consists of a main body plate 1, a push rod 2, a positioning rod 3, a compression spring 4, a spring force adjustment nut 5, and a top ball 6. The push rod 2 is an external thread structure and is threadedly connected to the inner hole of the main body plate 1. The positioning rod 3 is installed in the corresponding three position holes of the main body plate 1 in the same direction as the push rod 2. The compression springs 4 are respectively sleeved on the three positioning rods 3 installed on the main body plate 1. The positioning rod 3 is threadedly connected to the spring force adjustment nut 5, and the top ball 6 is embedded in the end of the bolt of the push rod 2.
[0011] In the magnetic powder brake disassembly device, the main body plate 1 adopts a three-point flying saucer-shaped structure and has a processed stress relief hole. The inner hole is an internal thread structure, and the mounting hole of the positioning rod 3 is a through hole.
[0012] When in use, first install the three positioning rods into the three original screw holes of the magnetic powder brake, adjust the appropriate height and adjust the position of the spring force adjustment nut so that the main plate and the bottom surface of the magnetic powder brake are as parallel as possible and the three compression springs have sufficient spring force to support the main plate, then rotate the top rod clockwise. When the top ball contacts the bag disc connecting shaft that is tightly matched with the magnetic powder brake, rotate it slowly, and the magnetic powder brake can slowly detach from the bag disc connecting shaft.
[0013] The above-described embodiments are merely preferred embodiments of the present invention. Those skilled in the art will appreciate that the present invention is not limited to the above-described embodiments and that various modifications and variations may be made to the present invention without departing from the scope and spirit of the present invention. These modifications and variations are intended to encompass such modifications and variations as long as they fall within the scope of the claims and their equivalents.
