Description

Technical Field

[0001] This utility model relates to the field of motor connection technology, and in particular to a motor rigid connection device. Background Technology

[0002] In industrial production and the operation of numerous mechanical equipment, motors serve as a critical power source, and the stability and reliability of their connection methods are of paramount importance. Traditional motor connection methods mainly include flexible connections and some simple rigid connections.

[0003] Flexible connections, such as those using belts and chains, while offering some protection against vibrations during motor startup and operation, have significant drawbacks. Belts and chains are prone to wear and elongation over time, leading to decreased transmission efficiency and requiring frequent adjustments and replacements, increasing maintenance costs and downtime. Furthermore, flexible connections exhibit elastic slippage during power transmission, hindering precise power delivery and making them unsuitable for equipment with high precision requirements. While some simple rigid connections offer more direct power transmission, their structural design is often flawed. For example, bolted connections can loosen under high-speed operation or heavy loads, causing gaps in the connection and resulting in vibration and noise, severely impacting the lifespan of the motor and equipment. Additionally, these simple rigid connections are cumbersome to install and disassemble, hindering equipment maintenance and repair.

[0004] Existing motor connection technologies have poor adaptability to complex operating conditions. For example, in high-precision machining equipment, even minute connection errors can lead to a decrease in machining accuracy and affect product quality. Furthermore, existing connection methods cannot guarantee a consistently high-precision connection under long-term operation and frequent load changes. Therefore, a rigid motor connection device is proposed to address these issues. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a motor rigid connection device, which aims to improve the problem that some devices in the prior art cannot be firmly fixed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A rigid connection device for an electric motor includes a rotating motor, a fixed clamping mechanism fixedly connected to the outside of the rotating motor, a rotating fixing mechanism fixedly connected to the outside of the rotating motor, and a supporting fixing plate fixedly connected to the outside of the rotating motor. The fixed clamping mechanism includes a telescopic cylinder, a fixing assembly for clamping and fixing fixedly connected to the outside of the telescopic cylinder, a fixing block, a connecting support rod fixedly connected to the outside of the fixing block, and a drive wheel fixedly connected to the outside of the connecting support rod.

[0008] As a further description of the above technical solution:

[0009] The rotating fixing mechanism includes a telescopic cylinder two, the output end of which is fixedly connected to a telescopic rod, and the outside of which is fixedly connected to a connecting support block;

[0010] As a further description of the above technical solution:

[0011] A connecting fixing rod is fixedly connected to the bottom of the connecting support rod, a clamping ring is fixedly connected to the bottom of the connecting fixing rod, and a fixing connecting block is fixedly connected to the outside of the drive wheel;

[0012] As a further description of the above technical solution:

[0013] The outer end of the connecting support rod, that is, the end away from the second fixed connecting block, is fixedly connected to the outside of the first fixed connecting block.

[0014] As a further description of the above technical solution:

[0015] The external of the connecting support block is rotatably connected to a rotating connecting ring, and the external of the rotating connecting ring is fixedly connected to a linkage rod.

[0016] As a further description of the above technical solution:

[0017] The linkage rod is rotatably connected to a rotating clamping block inside, and a supporting rotating shaft is rotatably connected to the outside of the rotating clamping block. A fixed supporting block is rotatably connected to the outside of the supporting rotating shaft.

[0018] As a further description of the above technical solution:

[0019] The external of the rotating clamping block is rotatably connected to the external of the rotating motor, and the external of the telescopic cylinder is fixedly connected to the external of the rotating motor.

[0020] As a further description of the above technical solution:

[0021] The rotating motor is externally fixedly connected to a second connecting rod, and the rotating motor is externally slidably connected to the outside of the first telescopic cylinder. The rotating motor is externally slidably connected to a clamping ring.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, when the telescopic cylinder one operates, it drives the connecting support rod to move. Since the fixed connecting block two fixes the connecting support rod to the outside of the telescopic cylinder one, the stability of the motion transmission is ensured. The movement of the connecting support rod then drives the two drive wheels to move. The fixed connecting block one firmly fixes the drive wheels to the connecting support rod, ultimately causing the clamping ring to move inward, ensuring accurate clamping and effectively improving the stability and reliability of the motor connection. Moreover, the use of a rigid connection method can enhance the overall rigidity of the device, reduce connection loosening and displacement, reduce the failure rate, extend the service life of the device, and provide a strong guarantee for the stable operation of the motor.

[0024] 2. In this utility model, when the telescopic cylinder 2 operates, it drives the telescopic rod to move. Since the telescopic rod is connected to the connecting support block, it in turn drives the connecting support block to move. The movement of the connecting support block, in turn, drives the rotating connecting ring and the linkage rod to move. The linkage rod causes the rotating clamping block to rotate on the supporting rotating shaft. The fixed support block provides stable support for the supporting rotating shaft, enabling the rotating clamping block to rotate and achieving reliable clamping of the motor components. The stable support structure enhances the overall stability and rigidity of the device, reduces the risk of loosening and failure, ensures the stability of the motor connection and the reliability of operation, improves work efficiency, and extends the service life of the device.

Detailed Implementation

[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0032] Reference Figure 1 , Figure 3This utility model provides an embodiment of a motor rigid connection device, including a rotating motor 1, a fixed clamping mechanism 2 fixedly connected to the outside of the rotating motor 1, a rotating fixing mechanism 3 fixedly connected to the outside of the rotating motor 1, and a supporting fixing plate 4 fixedly connected to the outside of the rotating motor 1. The fixed clamping mechanism 2 includes a telescopic cylinder 201 as a power driving component. When the telescopic cylinder 201 starts to run, it generates linear motion power. The telescopic cylinder 201 is fixedly connected to a fixing component for clamping and fixing. The fixing component includes a fixing connecting block 207, which plays a connecting and fixing role, and firmly connects the telescopic cylinder 201 and the connecting support rod 205 together. When the telescopic cylinder 201 moves, power is transmitted to the connecting support rod 205 via the fixed connecting block 207. The connecting support rod 205 is fixedly connected to the outside of the fixed connecting block 207, serving as an intermediate component for power transmission. It receives power from the telescopic cylinder 201 and transmits it to the drive wheel 203 and the connecting fixed rod 202. The drive wheel 203 is fixedly connected to the outside of the connecting support rod 205 and moves under its drive. The fixed connecting block 204 outside the drive wheel 203 fixes the drive wheel 203 to the connecting support rod 205, ensuring synchronous movement. The bottom of the connecting support rod 205 is fixedly connected to the connecting fixed rod 202, connecting the drive wheel 203 and the clamping ring 208. The movement of the drive wheel 203 is transmitted to the clamping ring 208, enabling the clamping ring 208 to move inward or outward. The bottom of the connecting fixed rod 202 is fixedly connected to the clamping ring 208. 8. Its inner side is slidably connected to the outside of the rotating motor 1. Under the drive of the connecting fixing rod 202, it can move inward toward the rotating motor 1 to clamp and fix the rotating motor 1, preventing the motor from shaking or shifting during operation. The outside of the drive wheel 203 is fixedly connected to the fixing connecting block 204, which firmly fixes the drive wheel 203 to the connecting support rod 205, ensuring that the drive wheel 203 will not loosen or shift during movement, thus ensuring the stability of power transmission. The outside of the connecting support rod 205, that is, the end away from the fixing connecting block 207, is fixedly connected to the outside of the fixing connecting block 204. The outside of the rotating motor 1 is fixedly connected to the connecting fixing rod 206, which strengthens the connection between the rotating motor 1 and the fixed clamping mechanism 2, improving the stability of the entire device. The outside of the rotating motor 1 is slidably connected to the outside of the telescopic cylinder 201. The outside of the rotating motor 1 is slidably connected to the inside of the clamping ring 208.

[0033] Reference Figure 1 , Figure 2 and Figure 4The rotating fixing mechanism 3 includes a second telescopic cylinder 301. A telescopic rod 302 at the output end can move linearly under the drive of the second telescopic cylinder 301. The output end of the second telescopic cylinder 301 is fixedly connected to the telescopic rod 302, transmitting the power of the second telescopic cylinder 301 to the connecting support block 303, causing the connecting support block 303 to move. The connecting support block 303 is fixedly connected to the outside of the telescopic rod 302, receiving the power of the telescopic rod 302 and transmitting it to the rotating connecting ring 304, enabling the rotating connecting ring 304 to rotate. The rotating connecting ring 304 is rotatably connected to the outside of the connecting support block 303, rotating under the drive of the connecting support block 303. The external linkage rod 305 moves with the rotation of the rotating connecting ring 304. The external linkage rod 305 is fixedly connected to the outside of the rotating connecting ring 304. A linkage 305 connects a rotating connecting ring 304 and a rotating clamping block 306, converting the rotational motion of the rotating connecting ring 304 into the rotational power of the rotating clamping block 306. The rotating clamping block 306 is rotatably connected inside the linkage 305 and rotates around a supporting rotating shaft 308 under the drive of the linkage 305. The supporting rotating shaft 308 is rotatably connected outside the rotating clamping block 306, providing rotational support for the rotating clamping block 306 and enabling it to rotate stably around it. A fixed support block 307 is rotatably connected outside the supporting rotating shaft 308, providing support and fixing for the supporting rotating shaft 308 and ensuring the stability of the rotation of the rotating clamping block 306. The external rotating clamping block 306 is rotatably connected to the outside of the rotating motor 1, and the telescopic cylinder 301 is fixedly connected to the outside of the rotating motor 1.

[0034] Working principle: When the telescopic cylinder 201 starts running, it drives the connecting support rod 205 to move, which in turn drives the two drive wheels 203 to move, which in turn drives the clamping ring 208 to move inward. Meanwhile, the fixed connecting block 204 fixes the drive wheel 203 to the connecting support rod 205, and the fixed connecting block 207 fixes the connecting support rod 205 to the outside of the telescopic cylinder 201.

[0035] When the external movement of the telescopic cylinder 301 begins, it drives the telescopic rod 302 to move, which in turn drives the connecting support block 303 to move, which in turn drives the rotating connecting ring 304 to move, and at the same time drives the linkage rod 305 to move, thereby causing the rotating clamping block 306 to rotate on the supporting rotating shaft 308, and the fixed support block 307 to provide support for the supporting rotating shaft 308.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model 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.
