Description

Technical Field

[0001] The present invention belongs to the technical field of motor protection devices, and specifically refers to a protection device for a mechatronic motor. Background Art

[0002] The motor casing is usually made of metal material and is a part of the motor. The motor casing is often also called the motor housing or motor casing cover. It can protect the internal components of the motor and also plays an important role in the motor structure. The motor casing generally consists of two parts, namely the motor base and the upper cover. The motor casing can isolate the internal components of the motor from the external environment and prevent external impurities such as dust, water vapor, and media from entering the motor, thereby protecting the internal electronic components of the motor from the influence of the external environment.

[0003] Existing motor protection devices can provide clamping and lifting effects for motor casings, but motor casings have a variety of sizes and the stiffness of motor casings has a certain limit. The strength of the casing materials of some motors is uneven and they are prone to deformation during assembly or processing. Especially when processing motor casings with damaged appearance, they need to be protected to prevent them from deformation. However, the existing technology cannot support the inside of the motor casing according to the different sizes of the motor casing. Therefore, it is necessary to propose a mechatronic motor protection device. Summary of the invention

The directional internal support assembly controls the bidirectional internal support assembly to tighten the side walls and top walls of the motor housing respectively, and the rotating assembly drives the bidirectional internal support assembly to rotate.

[0006] Furthermore, the directional inner support assembly includes a sliding plate, a connecting plate, an electrostrictive graft elastomer, and a limiting block.

[0012] The beneficial effects obtained by the present invention with the above structure are as follows: This solution provides a protection device for mechatronic motors, effectively solving the problem that the interior of the motor cannot be supported according to different sizes of the motor during motor assembly in the current market. This method brings the following advantages: (1) The vertical connecting rod and the horizontal connecting rod are respectively hinged on the connecting plates of the two sets of sliding plates. When the sliding plates move, they can drive the vertical web and the horizontal web to expand outwards, and then drive the horizontal support plate and the vertical support plate to expand outwards, tightly pressing against the motor housing, avoiding the problem that the motor housing is deformed and scrapped during the assembly and processing of the motor housing. Moreover, the vertical support plate and the horizontal support plate are not arranged along the entire length of the vertical web and the horizontal web, reducing the risk of accidentally touching the vertical support plate and the horizontal support plate during subsequent processing and preventing damage to the device; (2) A control switch is arranged on the horizontal support plate, and the control switch is electrically connected to the inner support motor, so that when the vertical support plate and the horizontal support plate tightly press against the motor housing, the inner support motor automatically stops working, preventing damage to the motor housing and increasing the safety of the device; (3) The electrostrictive grafted elastomer away from the inner support motor is electrified, causing the corresponding limit block to be snapped into the sliding tooth, so that the threaded cylinder can drive the slide plate away from the inner support motor to move, and then the vertical support plate expands outward, adjusting the distance between the vertical support plate and the top wall of the motor housing, achieving the effect of initially adjusting the vertical support plate according to the size of the motor housing, and then achieving the effect of the synchronous outward expansion of the horizontal support plate and the vertical support plate and the synchronous tightening of the two side walls and the top wall of the motor housing; (4) The limit strip is provided, the rotating ring is rotatably arranged on the threaded shaft, and the threaded cylinder is slidably arranged on the limit strip, so that the threaded cylinder can only slide along the direction of the threaded shaft, avoiding the rotation of the threaded cylinder with the threaded shaft and failing to play the role of tightening the motor housing; (5) The threaded shaft passes through the rotating hollow rod and the rotating main cone wheel, and the rotating hollow rod and the rotating main cone wheel do not rotate with the rotation of the threaded shaft, so that the rotation of the rotating hollow rod and the rotation of the threaded shaft do not affect each other. When the rotating hollow rod rotates, it drives the horizontal support plate and the vertical support plate to rotate, so that the motor housing rotates, facilitating the assembly and other work of the motor housing. While rotating, the vertical web and the horizontal web drive the vertical connecting rod and the horizontal connecting rod to rotate, thereby driving the two slide plates to rotate. And the two slide plates are rotatably arranged on the threaded shaft, providing the possibility for the rotation of the motor housing. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] During specific use, the electrostrictive graft elastomer 10 in the slide plate 8 far from the inner support motor 28 is electrified. The electrostrictive graft elastomer 10 in the slide plate 8 far from the inner support motor 28 elongates when electrified, driving the corresponding limit block 11 to move. The corresponding limit block 11 is inserted into the sliding tooth 16. According to the size of the motor housing, the inner support motor 28 is turned on. The inner support motor 28 drives the inner support output shaft 29 to rotate. The inner support output shaft 29 drives the inner support main cone wheel 31 to rotate. The inner support main cone wheel 31 drives the inner support secondary cone wheel 32 to rotate. The inner support secondary cone wheel 32 drives the threaded shaft 30 to rotate.
