Description

Technical Field

[0001] This utility model relates to the field of encoder installation technology, specifically to an alignment clamp that facilitates encoder installation. Background Technology

[0002] An encoder is a sensor that converts angular or linear displacement into electrical signals (such as pulse signals). It is widely used in industrial automation, robotics, CNC machine tools, and other fields. As a sensor, the encoder converts mechanical parameters such as the rotation angle and speed of the motor shaft into electrical signals (such as pulses or digital codes), which are then fed back to the controller. The motor then outputs power according to the controller's instructions, driving the load to move. The encoder is not a component of the motor itself, but it is typically mounted on the motor shaft. By monitoring position and speed in real time, the system can correct errors and dynamically adjust the output to ensure precise motor operation.

[0003] Encoders are often installed manually by hand. This installation method is not stable enough and requires the operator to have a very steady hand. It is not convenient for operators without much experience, which reduces the quality and efficiency of encoder installation. Utility Model Content

[0018] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein.

[0020] Secondly, this utility model is described in detail with reference to the schematic diagrams. When describing the embodiments of this utility model, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not adhering to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of this utility model. In addition, actual manufacturing should include the three-dimensional spatial dimensions of length, width, and depth.

[0021] Example 1 Reference Figure 1-4 This is the first embodiment of the present invention, which provides a worktable 1, an adjustment groove 2 on the top of the worktable 1, a motor 3 placed on top of the worktable 1, an encoder 4 arranged on the left side of the motor 3, a connecting block 5 arranged on the left side of the encoder 4, a square groove 6 on the right side of the connecting block 5, and a clamping mechanism and an adjustment mechanism arranged on top of the worktable 1. The clamping mechanism is used to clamp and fix the encoder 4 and the motor 3; The adjustment mechanism is used to adjust the height and left and right position of encoder 4.

[0022] Specifically, it achieves the effect of clamping and fixing the encoder 4 during installation, making it easier for staff to install the encoder 4, and also making it easy to adjust the height of the encoder 4 to accommodate motors 3 of different sizes.

[0023] Furthermore, the clamping mechanism fixes both the encoder 4 and the motor 3, further improving the stability and accuracy of the encoder 4 installation. Considering that the central shaft height of motors 3 of different sizes is also different, the adjustment mechanism makes it easy to adjust the height of the encoder 4 to adapt to motors 3 of different sizes, thus improving the practicality and functionality of the device.

[0024] The bottom of the workbench 1 is fixedly equipped with anti-slip support legs 19. The support legs provide stable support for the workbench 1 and prevent external forces from causing the workbench 1 to slide, ensuring stability during operation.

[0025] Example 2 The second embodiment of this utility model provides a clamping mechanism including a bidirectional lead screw 7, a connecting plate 8, a clamping block 9, a sliding plate 10, a fixing plate 11, a spring 12, and a clamping plate 13. The bidirectional lead screw 7 is rotatably connected to the inner wall of the square groove 6 via a bearing. The front end of the bidirectional lead screw 7 passes through the square groove 6 and extends to the front side of the connecting block 5. The surface of the bidirectional lead screw 7 is rotatably connected to the inner wall of the connecting block 5 via a bearing. The left end of the connecting plate 8 extends to the inner wall of the square groove 6 and is slidably connected to the square groove 6. The top of the connecting plate 8 is fixedly connected to the clamping block 9. The inner side of the clamping block 9 abuts against the encoder 4. The connecting plate 8 is throttle connected to the surface of the bidirectional lead screw 7. One end of the sliding plate 10 is slidably connected to one side of the connecting plate 8 via a T-shaped slider and a T-shaped groove. The right side of the sliding plate 10 is fixedly connected to the fixing plate 11. One side of the fixing plate 11 is fixedly connected to the spring 12. The other end of the spring 12 is fixedly connected to the clamping plate 13. One side of the clamping plate 13 abuts against the surface of the motor 3.

[0026] Specifically, the clamping mechanism fixes both the encoder 4 and the motor 3, further improving the stability and accuracy of the encoder 4 installation.

[0027] Furthermore, the operator rotates the bidirectional lead screw 7 via knob 18, thereby causing the two connecting plates 8 to slide along the inside of the square groove 6 and move closer to each other. The connecting plates 8 drive the clamping block 9 to move synchronously. The clamping block 9 contacts the encoder 4 and applies pressure to the encoder 4, achieving initial clamping of the encoder 4. When the connecting plates 8 move, they will drive the sliding plate 10 to move synchronously. The sliding plate 10 drives the fixed plate 11, spring 12 and clamping plate 13 to move synchronously, so that the clamping plate 13 contacts and abuts against the surface of the motor 3. After the clamping plate 13 contacts the motor 3, the fixed plate 11 will drive the spring 12 to continue to move. At this time, the spring 12 will be compressed. The spring 12 uses its elasticity to cooperate with the clamping plate 13 to fix the motor 3. The sliding plate 10 slides and cooperates with the T-shaped sliding groove connecting plate 8 through the T-shaped slider, which can stabilize the motor 3 without delaying the left and right movement of the encoder 4.

[0028] The connecting block 5 is slidably fitted onto the surface of the support plate 17. When the connecting block 5 moves up and down, it will move along the surface of the support plate 17. The support plate 17 provides guidance for the connecting block 5 to prevent it from deflecting during movement, which would cause the encoder 4 to shift position.

[0029] Example 3 The third embodiment of this utility model provides an adjustment mechanism including a first screw 14, a moving block 15, and a second screw 16. The bottom of the first screw 14 is rotatably connected to the moving block 15 via a bearing. A connecting block 5 is throttle-connected to the surface of the first screw 14. The moving block 15 is slidably connected to the inner wall of the adjustment groove 2. The right end of the second screw 16 is rotatably connected to the inner wall of the adjustment groove 2 via a bearing. The left end of the second screw 16 passes through the adjustment groove 2 and extends to the left side of the worktable 1. The surface of the second screw 16 is rotatably connected to the inner wall of the worktable 1 via a bearing.

[0030] Specifically, the height of the encoder 4 is easily adjustable to accommodate motors 3 of different sizes, thus improving the practicality and functionality of the device.

[0031] Furthermore, considering that the central shaft heights of motors 3 vary depending on their size, the operator rotates the first screw 14 using the knob 18. The first screw 14 drives the connecting block 5 to move up and down, thereby moving the clamping mechanism up and down and adjusting the height of the encoder 4 so that the center of the encoder 4 can be aligned with the central shaft of the motor 3. The operator then rotates the second screw 16 using the knob 18. The second screw 16 drives the moving block 15 to slide left and right in the adjusting groove 2, thereby adjusting the left and right position of the encoder 4 through the connecting block 5. The encoder 4 is moved to the right to connect with the motor 3, and then the operator fixes the encoder 4 to the motor 3 using the adapter screws.

[0032] The surface of the first screw 14 is rotatably connected to a support plate 17 via a bearing, and the bottom of the support plate 17 is fixedly connected to the movable block 15. The support plate 17 provides a second support point for the first screw 14, making the rotation of the first screw 14 more stable and smooth.

[0033] A knob 18 is fixedly connected to the front end of the bidirectional lead screw 7, the top of the first screw 14, and the left end of the second screw 16. The knob 18 facilitates the operation of the bidirectional lead screw 7, the first screw 14, and the second screw 16 by the operator, improving ease of operation and work efficiency.

[0034] Working principle: The operator rotates the bidirectional lead screw 7 via knob 18, causing the two connecting plates 8 to slide along the inside of the square groove 6 and move closer to each other. The connecting plates 8 drive the clamping block 9 to move synchronously, contacting the encoder 4 and applying pressure to it, thus initially clamping the encoder 4. As the connecting plates 8 move, they drive the sliding plate 10 to move synchronously. The sliding plate 10 then drives the fixed plate 11, spring 12, and clamping plate 13 to move synchronously, bringing the clamping plate 13 into contact with the surface of the motor 3. After the clamping plate 13 contacts the motor 3, the fixed plate 11 drives the spring 12 to continue moving, compressing it. The spring 12, using its elasticity, cooperates with the clamping plate 13 to fix the motor 3. The sliding plate 10 slides with the T-shaped sliding groove connecting plate 8 via a T-shaped slider, allowing the encoder 4 to move left and right while stabilizing the motor 3. The clamping mechanism fixes both the encoder 4 and the motor 3, further improving the stability and accuracy of the encoder 4 installation. Considering that the central shaft height of motors 3 varies with size, this... The operator rotates the first screw 14 using knob 18, which drives the connecting block 5 to move up and down, thereby moving the clamping mechanism up and down and adjusting the height of the encoder 4 so that the center of the encoder 4 can be aligned with the central shaft of the motor 3. The operator then rotates the second screw 16 using knob 18, which drives the moving block 15 to slide left and right in the adjustment groove 2, thereby adjusting the left and right position of the encoder 4 through the connecting block 5. The encoder 4 is moved to the right to connect with the motor 3, and then the operator fixes the encoder 4 to the motor 3 using the adapter screw. This allows for easy adjustment of the height of the encoder 4 to accommodate motors 3 of different sizes, improving the practicality and functionality of the device. The support plate 17 provides a second support point for the first screw 14, making the rotation of the first screw 14 more stable and smooth. The connecting block 5 moves along the surface of the support plate 17 when moving up and down, and the support plate 17 provides guidance for the connecting block 5 to prevent deflection during the movement of the connecting block 5, which would cause the encoder 4 to shift position.

[0035] In summary, the combination of the clamping mechanism and the adjustment mechanism enables the encoder to be clamped and fixed during installation, facilitating the installation process and allowing for easy adjustment of the encoder's height to accommodate motors of different sizes.
