Description
Technical Field
[0001] The present invention relates to the technical field of motors, and specifically to a general grating pasting device for an inner rotor DD motor. Background Art
[0002] A motor is a device that converts other forms of energy into mechanical energy to generate rotational or linear motion. Common types include electric motors, hydraulic motors, pneumatic motors, and heat engines. A DD motor is a motor that directly transmits power to a load without passing through intermediate transmission devices such as speed reducers, belts, and chains. Without the friction and vibration of intermediate transmission components, a DD motor runs with low noise and small vibration, and is suitable for fields such as medical equipment and optical instruments that have strict requirements for noise and vibration. When detecting a DD motor, it is often coordinated with a grating and related devices.
[0003] In the existing high-speed test of a DD motor, after installing a grating on the DD motor, the grating accurately monitors the rotational speed of the DD motor, facilitating the precise adjustment of the rotational speed by the control system to meet the requirements of different application scenarios for speed accuracy. However, the existing grating pasting fixtures are relatively bulky and not very versatile, basically dedicated to specific models of the same series, resulting in the inability to operate products of different models. Summary of the Invention
[0004] In view of the deficiencies of the prior art, the present invention provides a general grating pasting device for an inner rotor DD motor, which solves the problem that products of different models cannot be operated due to the relatively bulky and not very versatile existing grating pasting fixtures.
[0005] To achieve the above objectives, the present invention is realized through the following technical solutions: A general grating pasting device for an inner rotor DD motor includes a bottom plate.

[0014] Preferably, the structural layer is made of aluminum alloy.
[0015] Working principle: By pushing the first carriage to drive the first column to move, then the slider slides under the drive of the first column. At the same time, an anti-collision block is provided at the end of the guide rail, which can prevent the slider from detaching from the surface of the guide rail. Then, the second column is used to limit the height and position of the second carriage, and the product limiting block remains stable under the fixation of the second carriage.

[0028] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.
[0029] Please refer to the attached Figure 1 - attached Figure 3 , the embodiment of the present invention provides a general grating pasting device for an inner rotor DD motor, including a base plate 1. A sliding assembly is arranged on the upper surface of the middle part of the base plate 1. The sliding assembly is connected with a first column 5. The upper surface of the first column 5 is fixedly connected with a first carriage 6. A clamping assembly 10 is arranged on the upper surface of the first carriage 6. A second column 7 is fixedly connected to the upper surface of the front side of the base plate 1. The sliding assembly is connected with the second column 7. A limiting assembly is arranged on the upper surface of the second column 7. An anti-collision block 2 is fixedly connected to the upper surface of the rear side of the base plate 1;
[0030] Specifically, by pushing the first carriage 6, the clamping assembly 10 is driven to move synchronously. Since the first column 5 is fixedly connected to the first carriage 6, the first column 5 moves synchronously under the drive of the first carriage 6. Since the sliding assembly is connected to the first column 5, the first column 5 moves along a specified trajectory under the restriction of the sliding assembly. The sliding assembly is used to prevent the movement of the first column 5 from deviating from the expectation, while the anti-collision block 2 is used to prevent the sliding assembly from detaching from above the bottom plate 1. Then, the position and height of the limiting assembly are fixed by the second column 7. At this time, the product is fixed above the bottom plate 1 under the clamping of the clamping assembly 10 and the limiting assembly. Since the position of the first carriage 6 is flexible and adjustable, the clamping assembly 10 and the limiting assembly can fix products of different sizes, so as to facilitate the user to clamp and fix products of different sizes and shapes to maintain stability during processing and enhance the versatility effect.
[0031] Refer to the appendix Figure 1 and the appendix Figure 2 As shown, the sliding assembly includes a guide rail 3. The lower surface of the guide rail 3 is fixedly connected to the middle upper surface of the bottom plate 1. The outer wall of the guide rail 3 is slidably connected with a slider 4. The lower surface of the first column 5 is fixedly connected to the upper surface of the slider 4;
[0032] Specifically, since the slider 4 is fixedly connected to the first column 5, the slider 4 slides along the surface of the guide rail 3 under the drive of the first column 5. At the same time, an anti-collision block 2 is provided at the end of the guide rail 3. The anti-collision block 2 limits the sliding distance of the slider 4 and prevents the slider 4 from detaching from the surface of the guide rail 3.
[0033] Refer to the appendix Figure 1 and the appendix Figure 3 As shown, the clamping assembly 10 includes a guide block 103. The lower surface of the guide block 103 is fixedly connected to the upper surface of the first carriage 6. The outer wall of the guide block 103 is fixedly connected with a fixing plate 104. The inner wall of the fixing plate 104 is threadedly connected with a clamping screw 105. The outer wall of the clamping screw 105 is threadedly connected with a second push block 102. The outer wall of the second push block 102 is fixedly connected with a first push block 101; The side wall of the second push block 102 is slidably connected to the inner wall of the guide block 103. The lower surface of the second push block 102 is slidably connected to the upper surface of the first carriage 6. The lower surface of the first push block 101 is slidably connected to the upper surface of the first carriage 6;
[0034] Specifically, by rotating the nut connected to the clamping screw 105, the clamping screw 105 rotates inside the fixing plate 104. Then, the clamping screw 105 drives the second push block 102 to slide along the inner wall of the guide block 103. Since the first push block 101 is fixedly connected to the second push block 102, the first push block 101 slides on the surface of the first carriage 6 under the drive of the second push block 102. The first push block 101 fits on the surface of the product to further fix the product.
[0035] Refer to the appendix Figure 1 and the appendixFigure 2 , a weight-reducing groove 11 is formed inside the bottom plate 1;
[0036] Specifically, by forming a large-area weight-reducing groove 11 inside the bottom plate 1, while ensuring the stability of the bottom plate 1, space is provided for placing the product. The device reduces weight by using lightweight materials while forming large-area grooves, and the components of the device are tightly connected to further reduce the volume. Finally, the overall lightweight and miniaturization of the device are achieved, thus achieving the effect of facilitating the user to quickly transfer and deploy the device.
[0037] Refer to the appendix Figure 2 , the limiting component includes a second drag plate 8. The lower surface of the second drag plate 8 is fixedly connected to the upper surface of the second column 7, and a product limiting block 9 is fixedly connected to the upper surface of the second drag plate 8;
[0038] Specifically, the second column 7 is used to limit the height and position of the second drag plate 8, and then the product limiting block 9 remains stable under the fixation of the second drag plate 8 to facilitate clamping the product.
[0039] Refer to the appendix Figure 4 and the appendix Figure 5 , the inside of the guide rail 3 includes a structural layer 14. The outer wall of the structural layer 14 is fixedly connected with a damping layer 13, and the outer wall of the damping layer 13 is fixedly connected with a wear-resistant layer 12;
[0040] Specifically, the guide rail 3 is composed of multiple materials in combination. The guide rail 3 includes a wear-resistant layer 12, a damping layer 13, and a structural layer 14, so as to reduce the friction between the slider 4 and the guide rail 3, reduce wear, improve the movement efficiency and accuracy, reduce the influence of vibration on the grating accuracy and the motor operation, absorb noise, and ensure the structural stability and reliability of the guide rail 3.
[0041] Refer to the appendix Figure 5 , the wear-resistant layer 12 is made of polytetrafluoroethylene;
[0042] Specifically, polytetrafluoroethylene is a high molecular polymer obtained by polymerizing tetrafluoroethylene as a monomer. It has a low friction coefficient and can effectively reduce the frictional force between the slider 4 and the guide rail 3. This enables the wear-resistant layer 12 to reduce energy loss, improve movement efficiency, and at the same time has good self-lubricity and chemical stability, can maintain stable performance in different working environments, reduce wear, and extend the service life of the guide rail 3.
[0043] Refer to the appendix Figure 5 , the damping layer 13 is made of butyl rubber;
[0044] Specifically, butyl rubber is a synthetic rubber with good damping characteristics, which enables the damping layer 13 to absorb the vibrations and noises generated during the movement of the guide rail 3, reduce the impact of vibrations on the grating accuracy and motor operation, improve the stability and reliability of the device, and also play a buffering role to protect the guide rail 3 and other components from impacts.
[0045] Refer to the appendix Figure 5 , and the structural layer 14 is made of aluminum alloy;
[0046] Specifically, aluminum alloy is an alloy based on aluminum with a certain amount of other alloying elements added. It is one of the light metal materials, characterized by a small density and light weight, which enables the structural layer 14 to reduce the weight of the entire device while ensuring the structural strength, facilitating installation and movement.
