Description

Technical Field

[0001] This utility model relates to the technical field of single-piece electromagnetic brakes for printing presses, specifically a single-piece electromagnetic brake for printing presses. Background Technology

[0002] An electromagnetic brake is a connector that transmits torque from the active side to the passive side. It can be freely engaged, disengaged, or braked as needed. Because it uses electromagnetic force for actuation, it is also called an electromagnetic clutch or brake. It has advantages such as fast response speed and simple structure. Electromagnetic brakes can be divided into various forms, including electromagnetic powder brakes, electromagnetic eddy current brakes, and electromagnetic friction brakes. They are further subdivided into dry single-plate electromagnetic brakes, dry multi-plate electromagnetic brakes, wet multi-plate electromagnetic brakes, and so on.

[0003] When using electromagnetic brakes in existing technologies, the friction pads are tightly sealed, making it difficult to manually disassemble them for replacement, which leads to inconvenience in maintaining the electromagnetic brakes. Utility Model Content

[0004] The purpose of this invention is to provide a single-chip electromagnetic brake for a printing press to solve the problems mentioned in the background art.

[0005] To solve the above-mentioned technical problems, this utility model provides a single-piece electromagnetic brake for a printing press, comprising a housing, a top cover fixedly sleeved on the top of the housing, a rotating shaft movably sleeved inside the housing, a brake disc fixedly sleeved outside the rotating shaft, an electromagnetic coil fixedly installed inside the housing, a push post movably sleeved on the side of the electromagnetic coil, a locking block fixedly connected to one end of the push post, a friction plate movably sleeved inside the housing, a limit sleeve fixedly connected to the side of the friction plate, a sliding ball movably sleeved on the side of the inner wall of the limit sleeve, a sealing ring fixedly sleeved on the top of the housing, and a closing mechanism provided on the front of the housing.

[0006] Preferably, the locking block is movably sleeved inside the limiting sleeve, and there are three locking blocks, which are evenly distributed around the rotation axis on the side of the electromagnetic coil.

[0007] Preferably, the number of sliding balls is several, and the several sliding balls are evenly distributed on the side of the inner wall of the limiting sleeve.

[0008] Preferably, the sealing ring is made of rubber and is in close contact with the bottom of the top cover.

[0009] Preferably, the closing mechanism includes a first positioning block, which is fixedly connected to the front of the top cover, and a second positioning block is fixedly connected to the front of the housing. The first positioning block has a bolt threaded into its internal thread.

[0010] Compared with the prior art, the beneficial effects of this utility model are as follows: This single-piece electromagnetic brake for printing machines, by setting a locking block, when the internal friction plate of the brake is severely worn due to long-term use and needs to be replaced, the top cover is removed, and the friction plate is lifted so that it can be moved out of the inside of the housing, thereby achieving the effect of disassembling the friction plate. Then, the intact friction plate is sleeved on one end of the push column, so that the friction plate is limited and fixed inside the housing, thereby achieving the effect of replacing the friction plate, thus bringing convenience to the maintenance of the brake; In addition, the single-piece electromagnetic brake of this printing press is equipped with a closed mechanism. When the friction plate needs to be disassembled and replaced, the bolt is rotated so that the bolt can be moved out from inside the second positioning block. At this time, the top cover is lifted so that the top cover can be separated from the housing, thereby separating the housing and achieving the disassembly effect of the brake, thus bringing convenience to the disassembly and maintenance of the brake.

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0017] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0018] Please see Figure 1-3 An embodiment of this utility model provides a single-piece electromagnetic brake for a printing machine, comprising a housing 1, a top cover 2 fixedly sleeved on the top of the housing 1, a rotating shaft 3 movably sleeved inside the housing 1, a brake disc 4 fixedly sleeved outside the rotating shaft 3, an electromagnetic coil 5 fixedly installed inside the housing 1, a push post 6 movably sleeved on the side of the electromagnetic coil 5, a locking block 7 fixedly connected to one end of the push post 6, a friction plate 8 movably sleeved inside the housing 1, a limiting sleeve 9 fixedly connected to the side of the friction plate 8, a sliding ball 10 movably sleeved on the side of the inner wall of the limiting sleeve 9, a sealing ring 11 fixedly sleeved on the top of the housing 1, and a sealing mechanism 12 provided on the front of the housing 1.

[0019] The locking block 7 is movably sleeved inside the limiting sleeve 9, and there are three locking blocks 7. The three locking blocks 7 are evenly distributed around the rotating shaft 3 on the side of the electromagnetic coil 5. By setting the locking blocks 7, when the brake has been used for a long time and the internal friction plate 8 is severely worn and needs to be replaced, the top cover 2 is removed. At this time, the friction plate 8 is lifted, so that the friction plate 8 can be moved out from the inside of the housing 1, thereby achieving the disassembly effect of the friction plate 8. Then, the intact friction plate 8 is sleeved on one end of the push column 6, so that the friction plate 8 can be limited and fixed inside the housing 1, thereby achieving the replacement effect of the friction plate 8, thus bringing convenience to the maintenance of the brake.

[0020] The number of sliding balls 10 is several, and the several sliding balls 10 are evenly distributed on the side of the inner wall of the limiting sleeve 9. By setting the sliding balls 10, when the friction plate 8 is disassembled or assembled, the sliding balls 10 can limit the limiting sleeve 9, thereby avoiding the problem of frequent friction between the limiting sleeve 9 and the locking block 7 during disassembly and assembly, which would make it difficult to disassemble or assemble the friction plate 8, thus improving the smoothness of disassembling the friction plate 8.

[0021] The sealing ring 11 is made of rubber and is in close contact with the bottom of the top cover 2. By setting the sealing ring 11, when the brake is assembled and fixed, the sealing ring 11 can fill the gap between the housing 1 and the top cover 2, thereby improving the sealing effect inside the housing 1, that is, improving the internal sealing performance of the brake after assembly.

[0022] The closing mechanism 12 includes a first positioning block 121, which is fixedly connected to the front of the top cover 2. A second positioning block 122 is fixedly connected to the front of the housing 1. A bolt 123 is threaded into the inside of the first positioning block 121. By setting the closing mechanism 12, when the friction pad 8 needs to be disassembled and replaced, the bolt 123 is rotated so that the bolt 123 can be moved out from the inside of the second positioning block 122. At this time, the top cover 2 is lifted so that the top cover 2 can be separated from the housing 1, thereby separating the housing 1 and achieving the disassembly effect of the brake, thus bringing convenience to the disassembly and maintenance of the brake.

[0023] Working principle: When the brake requires replacement due to severe wear of the internal friction pad 8 after prolonged use, the top cover 2 is removed. This allows the friction pad 8 to be lifted and removed from the housing 1, thus achieving disassembly. The intact friction pad 8 is then fitted onto one end of the push post 6, securing it within the housing 1 and facilitating replacement. This simplifies brake maintenance. During friction pad 8 installation and removal, the sliding ball 10 limits the position of the limiting sleeve 9, preventing frequent friction between the limiting sleeve 9 and the locking block 7, which could hinder friction pad 8 installation and removal, thereby improving friction efficiency. The smoothness of disassembling the friction pad 8 is achieved by filling the gap between the housing 1 and the top cover 2 during brake assembly and fixing, thereby improving the sealing effect inside the housing 1, which in turn improves the internal sealing performance of the brake after assembly. When the friction pad 8 needs to be disassembled and replaced, the bolt 123 is rotated so that the bolt 123 can be moved out from inside the second positioning block 122. At this time, the top cover 2 is lifted so that the top cover 2 can be separated from the housing 1, thereby separating the housing 1 and achieving the disassembly effect of the brake. This brings convenience to the disassembly and maintenance of the brake. The contents not described in detail in this specification are existing technologies known to those skilled in the art.

[0024] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
